The current study examines associations between self- and teacher-rated temperament traits (activity, inhibition, negative emotionality, persistence, distractibility, and mood) and mathematics grades. The sample includes 310 ninth grade students (mean age 15.0) from several schools in Finland. Analyses were conducted
with multilevel modeling. Except for mood, all temperament traits were associated with math grades independent of motivation and standardized cognitive ability test performance (intelligence). However, some relations were found only for teacher-reports and some only for student-reports. The rater dependent
differences are of interest and emphasize a need for data from multiple raters before drawing conclusions
on how temperament relates to school grades. The results suggest that temperament should be taken into account in schooling and in teacher education.

1. Introduction
Academic achievement is an early milestone in developmental
pathways leading to adult psychological and social outcomes. For example, it predicts factors related to social adjustment, such as social
competence and peer acceptance (Chen, Rubin, & Li, 1997). Moreover,
school performance is associated with adjustment problems, health,
and well-being later in life. Lower academic achievement has been
shown to predict somatic health risks (Alatupa et al., 2010; Bryant,
Schulenberg, Bachman, O'Malley, & Johnston, 2000; Huurre et al.,
2010) and depression (Chen, Rubin, & Li, 1995). Academic achievement is also predictive of future educational attainment
(Marjoribanks, 2005), socioeconomic position (Guglielmi, 2008;
Judge & Hurst, 2007), and the risk of unemployment in adulthood
(Caspi, Wright, Moffitt, & Silva, 1998). In the future, especially the importance of education related to science, technology, engineering and
math is increasing rapidly as the occupations related to these fields
demand more and more employees (Carnevale, Smith, & Melton,

2011). For this reason, skills in mathematics and related subjects
have special importance for the individual as well as for the society.
It is important to identify factors that predict mathematics
achievement in order to be able to intervene and help students to
perform better. Adjustment to school and school performance can
be seen to be dependent on the goodness of fit between an individual's cognitive and socio-emotional capacity and an individual's environment (Thomas & Chess, 1977, 1980). A poor fit, resulting from
disparity between individual characteristics and environmental demands, may lead to negative outcomes (Thomas & Chess, 1980). In
the school setting, a poor fit may result in reduced motivation, distractions in the learning process and diminished learning capacity.
In this context, temperament traits play an especially important role.
Temperament describes the how of behavior in contrast to the
what and why of behavior that are related to ability and motivation,
respectively (Thomas & Chess, 1977). Temperament traits are comparatively stable biologically based behavioral tendencies that appear
early in life (Goldsmith et al., 1987) and have heritable underpinnings
(Keller, Coventry, Heath, & Martin, 2005). Furthermore, temperament
is thought to form a basis for personality development. According to
an extensive review by Strelau (1998), temperament is more closely
related to biology and it is postulated to be present already in early
childhood, whereas personality is more strongly affected by social
factors, and emerges later as a result of socialization and learning.
These kinds of differences separate temperament traits from most
personality traits (Strelau, 1998). Although most temperament research has focused on children, temperament remains relevant also
in adolescence and adulthood (Thomas & Chess, 1977).
M. Hintsanen et al. / Learning and Individual Differences 22 (2012) 490–497
Temperament traits predict attention (Curtindale, Laurie-Rose,
Bennett-Murphy, & Hull, 2007), interests, motivation (Elliot &
Thrash, 2002), cognitive strategies (Davis & Carr, 2002), and therefore
also working styles (Kristal, 2005). Some studies have shown that associations of temperament and factors related to working styles are
moderate or large in magnitude (Davis & Carr, 2002). Temperament
traits may contribute to adjustment to the requirements of school environment or create extra challenges to it.
In the school context, a combination of traits forming a factor
called task orientation, has been shown to be of particular relevance
(Oliver, Guerin, & Gottfried, 2007). Task orientation is one of the
three temperament factors describing an ideal student who is, in a
teacher's view, easy to teach (Keogh, 1994). Students with high task
orientation can engage in and finish tasks despite disruptions, and
they are able to moderate and direct their activity according to the
task at hand (Keogh, 1983). Therefore, task orientation can be seen
as having close connections with working styles. High task orientation is formed by a temperament trait combination of high persistence, low activity and low distractibility (Keogh, 1983). Activity
refers to a tendency to show high motor activity, whereas persistence
refers to the ability to concentrate and engage in tasks for long periods of time (Martin & Bridger, 1999). Characteristic to distractibility
is the tendency to easily shift attention to surrounding stimuli instead
of being able to concentrate on the task at hand (Windle, 1992;
Windle & Lerner, 1986).
Another two temperament constellations related to a teachers'
view of an ideal, teachable student are personal–social flexibility
and reactivity, the first of which includes temperament traits high
adaptability, tendency to approach rather than withdraw and positive mood, whereas the latter constellation includes negative mood
and tendency to respond to slightest cues with intensity (Keogh,
1983). Traits related to personal–social flexibility and reactivity
may be associated to working styles but they are more likely to be
related to social interaction and emotional adjustment, which may
then be reflected in motivation and teacher's evaluations. We assess
personal–social flexibility with two traits: low inhibition and high
mood. Inhibition is a tendency to be careful and to hesitate in unknown and social situations (Martin & Bridger, 1999), whereas
mood refers to a tendency to experience and show positive affect
(Windle, 1992; Windle & Lerner, 1986). We assess reactivity with
one trait: negative emotionality refers to a tendency to easily experience negative feelings such as anger and irritation (Martin &
Bridger, 1999).
Empirical evidence of the association between temperament and
academic achievement is limited (Martin & Holbrook, 1985; Zhou,
Main, & Wang, 2010). Previous research on mathematics achievement, has shown most support (in general, with moderate to strong
associations) for better math achievement being associated with
traits forming high task orientation, i.e. high persistence, low distractibility and low activity (Bramlett, Scott, & Rowell, 2000; Guerin,
Gottfried, Oliver, & Thomas, 1994; Martin, 1989; Martin & Holbrook,
1985; Mullola et al., 2010). Few studies and findings on negative
emotionality, mood, and inhibition exist. Higher negative emotionality, lower mood, and higher inhibition have been found to correlate
with lower math grades although the correlations have been only
small in size (Mullola et al., 2010).
While previous studies suggest that temperament traits may be
related to mathematics achievement, there are some important limitations in existing research. The majority of studies on temperament
and math achievement have included small samples of approximately
100 participants or less (Bramlett et al., 2000; Checa, RodríguezBailón, & Rueda, 2008; Guerin et al., 1994; Martin & Holbrook, 1985;
Martin, Nagle, & Paget, 1983; Mevarech, 1985). Data have often
been collected from one (Checa et al., 2008; Martin & Holbrook,
1985) or only few schools (Martin et al., 1983; Mevarech, 1985) and
few classes, which may limit the generalizability of the findings.

Furthermore, most previous publications on temperament and
mathematics achievement have focused on age groups between the
ages of four and 10 (Bramlett et al., 2000; Martin & Holbrook, 1985;
Martin et al., 1983; Mevarech, 1985; Rudasill, Gallagher, & White,
2010). However, the associations of temperament with mathematics
achievement might be expected to become stronger with age. In
mathematics, one topic is practiced for a long time, after which, it is
expected to be mastered. Furthermore, learning new things is based
on skills learned before. If one lags behind, it might be difficult to
catch up, and these difficulties are likely to accumulate over time.
Consequently, the strongest associations with temperament may be
seen most clearly in the final school years. Although only few studies
have examined this issue, it has been reported that the association
between temperament traits and math performance seem to get
somewhat stronger with increasing age (Guerin et al., 1994;
Maziade, Cote, Boutin, Boudreault, & Thivierge, 1986).
A recent large-scale study reported associations between
teacher-rated temperament traits and mathematics grades (Mullola
et al., 2010) but this study did not take into account student's selfrated temperament and cognitive ability assessed with standardized
test. In the current study, we examine associations of self- and
teacher-rated temperament with math grades in a sample of 310
ninth graders from several schools and classes in Finland. Self- and
teacher-ratings of temperament are included in order to improve
the validity and to examine whether the findings are dependent
on the rater. Very few previous studies have included self- or
parent-ratings alongside with teacher-ratings (Bramlett et al.,
2000). Temperament measures that are used are based on the temperament theory by Thomas and Chess (1977) that describes nine
temperament traits. Our study included fewer traits for instance
leaving out rhythmicity that was considered somewhat difficult to
assess in school setting where curricular activities largely define
the daily rhythms. We use Martin's temperament inventory that
has been especially developed for the school setting (Martin &
Bridger, 1999). Measures were complemented with two relevant
scales from another inventory (Windle, 1992) as these traits were
not included in Martin's measure. We include student motivation
and standardized math-related cognitive test performance as they
may be explaining factors in the association between temperament
and math grades. We aim to examine which temperament traits
are associated with math grades, and whether these associations
are independent of motivation and cognitive ability test performance. Based on previous research we hypothesized that higher
persistence and mood and lower distractibility, activity, negative
emotionality and inhibition would be associated with higher
math grade.
The Finnish school system is very homogenous which has been
demonstrated for example as the lowest between-school variance in
science performance among 54 countries in PISA study in 2006
(OECD, 2009). Finnish schools show little quality differences and little
selection related to age, gender, motivation or ability of the students.
Residential areas are not highly segregated and the vast majority of
students are enrolled to the nearest school. Private schools are virtually non-existent. In all schools, teaching is organized according to the
same national curriculum. Furthermore, all teachers receive university education reducing the differences between teachers. This comparatively homogenous environment reduces school and teacher
related variance and therefore offers a good setting for examining
individual variance in academic achievement.
2. Material and methods
2.1. Participants
The subjects were 354 ninth graders who participated in a sub-study
of the research project “The Finnish Study on Temperament and School
492
M. Hintsanen et al. / Learning and Individual Differences 22 (2012) 490–497
Achievement” (Alatupa, Karppinen, Keltikangas-Järvinen, & Savioja,
2007). Finnish school system consists of 9 years of compulsory schooling
starting when the children are seven-year-olds. Lower-comprehensive
school (grades 1–6) encompasses the first 6 years and uppercomprehensive school (grades 7–9) the last 3 years. Therefore, ninth
grade is the final year of compulsory schooling during which the students
are aged 15 or 16 years. In upper-comprehensive schools, teachers are
subject teachers and every subject is, therefore, taught by a different
teacher. The data were collected in 2005–2006 in upper-comprehensive
schools in the areas of Lahti and Kirkkonummi in southern Finland. All
schools in these areas were first listed and then randomly selected for
the current study. In case a school refused to participate, the next school
on the list was selected. As a result, the sample consisted of 354 students
in 11 schools. Swedish-speaking and special schools were not sampled.
All students voluntarily completed a test battery during regular class sessions. The participants with information on all study variables formed the
final sample (N=309). The mean age of the participants was 15.0 years
(S.D.=0.34). The sample included 144 girls (46.6%) and 165 boys
(53.4%). In the final sample, the students were from 11 different schools
and from 18 classes. In addition to the students, their teachers were
asked to participate as additional raters. Teacher-ratings were obtained
in 5 months time period between October and February. There were 18
teachers in the final data of the current study. The same teacher is responsible for teaching a certain group of students throughout the whole
upper-comprehensive school, i.e. through grades 7–9. Therefore, the
teachers had been teaching these students more than two school years.
A majority of the teachers were women (n=16). The mean age of the
teachers was 43.2 years. The teachers were not paid for their contribution.
2.2. Measures
2.2.1. Mathematics grades
In a written sheet, the students were asked to report their math
grade in their latest school report (report from the autumn term or
from the preceding spring term). The final grades from ninth school
year had not been assigned during the data collection (lasting from
October to end of February). The grades range between 4 and 10
(4 = fail, 5–6 = poor, 7–8 = good, and 9–10 = excellent).
2.2.2. Temperament
Self- and teacher-reports were used to assess students' temperament. Scale meanings and the numbers of items are presented in
Table 1. Information on temperament was collected using two different measures. First, four scales of the Temperament Assessment
Battery for Children Revised (TABC-R) (Martin & Bridger, 1999)
were used: inhibition (see Table 1 for the items), persistence, negative emotionality, and activity. Some of the items of TABC-R were
slightly modified to be more age appropriate for the current participants. Secondly, two scales from the Revised Dimensions of Temperament Survey (DOTS-R) (Windle, 1992) were applied: mood
and distractibility. All items were answered on a five-point scale,
ranging from 1 (strongly disagree) to 5 (strongly agree). Temperament scores were calculated only for those participants who had
answered to at least 50% of the items of a scale. Others were excluded from the analyses. In The Finnish Study on Temperament
and School Achievement data (i.e. the data of the current study),
the following internal reliabilities (Cronbach's α) have been previously reported for inhibition, persistence, negative emotionality, activity, mood and distractibility, respectively: 0.83, 0.60, 0.65, 0.51,
0.91 and 0.72, for self-reported temperament (Hintsanen, Alatupa,
Pullmann, Hirstiö-Snellman, & Keltikangas-Järvinen, 2010) and
0.90, 0.93, 0.81, 0.86, 0.96, and 0.91 for teacher-rated temperament
(Mullola et al., 2010).
2.2.3. Motivation
General school motivation was self-reported with six-items
(α = 0.69), e.g. “My school work is very important to me” and “If I
want, I can improve my results”. Answers were rated on a five-point
scale, ranging from 1 (strongly disagree) to 5 (strongly agree). The
motivation scale was developed for this particular study.
2.2.4. Cognitive ability test performance
Cognitive ability was assessed with three standardized tests (R1,
R3, and V3) developed for assessing components of cognitive performance in vocational guidance in the age group of the current study
(Pulliainen, 1994). Tests R1 and R3 assess inference skills. R1 is a
task of code language and R3 is a task of analogies. Test V3 includes
tasks where complicated instructions have to be followed. There are
various kinds of V3 tasks including inference tasks and math problems (Pulliainen, 1994). The test scores were standardized so that a
mean of 0 and standard deviation of 1 were achieved. After that, the
mean of these three test scores was calculated and the formed variable (α = 0.74) was used in the analyses.
2.2.5. Non-attendance
The amount of days absent from school during the last semester
was self-reported by the students on a following scale: 1—none
(n = 51), 2—a few days (n = 201), 3—a few weeks (n = 53), 4—several
months (n = 5).
2.3. Statistical analyses
The associations between independent variables (teacher-rated
and self-rated temperament) and dependent variable (math grade)
were assessed with random-intercept multilevel modeling using restricted maximum-likelihood estimation (REML). Separate models
were fitted for teacher-rated and self-rated temperament with students being nested within teachers and school classes (the sample included only one teacher for each class).
Multilevel modeling calculates the standard errors of regression
coefficients by taking into account the clustered nature of the
data, i.e., the non-independence of the first-level observations
(students) nested within second-level groups (teachers/classes).
Intra-class correlation was 0.09 (i.e. the second-level, i.e. teacher
or class, explained 9% in math grade). All student-level continuous
independent variables were standardized before conducting the
analyses. First, a random intercept model was calculated. Second,
a random coefficient model was calculated. Model and covariance
structure (diagonal, unstructured) was chosen by considering
changes in Akaike's information criteria along with maximizing
the amount of significant covariance parameters (p b 0.1 as a criterion). Chosen models and covariance structures are reported in
Tables 4 and 5.
Each teacher-rated temperament trait was examined separately
with the following variables included as first-level variables in addition to the temperament trait in question: model 1) student's age
and gender, model 2) student's age, gender, motivation, ability test
score and amount of non-attendance by the student. The same procedure was followed in examining self-rated temperament. Estimates of effect sizes for the whole model (Adjusted R 2) and for the
temperament traits (R 2 change) were calculated with linear regression analyses as there are still not well-established methods for calculating effect sizes in multilevel modeling (Hox, 2010).
Gender interactions predicting math achievement were in general
not significant except for interaction with self-rated inhibition
(p = 0.043) which we considered to be a chance finding due to the
number of interaction analyses performed. Therefore, all analyses
were performed for a combined sample of girls and boys. All analyses
were conducted with a mixed procedure in SPSS 15.0 software.

3. Results
3.1. Bivariate correlations
Table 2 presents study characteristics and Table 3 presents bivariate correlations between study variables. Higher teacher-rated persistence and mood and lower activity, inhibition, negative
emotionality, and distractibility were correlated with higher math
grade. Of the student-rated temperament traits only higher persistence and inhibition and lower distractibility were correlated with
higher math grade. Higher motivation and especially higher ability
test score were also correlated with higher math grade. Correlations
between self- and teacher-ratings of a given temperament trait were
the following: activity r = .120, p b .05; inhibition r = .371, p b .01;
negative emotionality r = .109, p = ns; persistence r = .219, p b .01;
distractibility r = .231, p b .01; mood r = .317, p b .01. All teacherrated temperaments correlated with ability test score, whereas of
the student-rated temperament traits, only persistence correlated
with it.
3.2. Associations between temperament and math grade
Table 4 presents the results of multilevel modeling analyses for
teacher-rated temperament traits. In multilevel modeling, a random
intercept model was chosen for all analyses on self-rated temperament and for a majority of analyses on teacher-rated temperament
as can be seen in Tables 4 and 5. High teacher-rated persistence and

4. Discussion
Our findings demonstrate that temperament is associated with
math grades even when motivation and cognitive ability are taken
into account. Thus, the relation between temperament and math
grade is independent of motivation and standardized cognitive ability
test performance. This is an important observation because cognitive
ability is a strong predictor of academic achievement (Deary, Strand,
Smith, & Fernandes, 2007). Our results imply that in addition to cognitive ability, math grades reflect other factors.
Self- and teacher-rated temperaments were associated with
math-related cognitive ability test performance but associations to
math grades were, in general, stronger. All temperament traits were
related with math grades but associations for negative emotionality
and mood were only found in teacher-reports, whereas associations
for inhibition were only found in self-reports.
There are at least four possible mechanisms that may explain the
associations between temperament and math grades. First, temperament may be associated with math grades via cognitive working
styles (e.g. tendency to use verbalization or visualization). There is
evidence on associations between temperament traits and preferences to use certain strategies (Davis & Carr, 2002).

Second, temperament may be associated with math grades
through the ability to adapt to the many demands the school environment sets to the students. For instance, one has to be able to sit still
and concentrate despite of the noisy environment.
Third, the teacher's perceptions of student temperament may
bias their grading of a student's school performance (the so-called
halo effect). Teachers may, for instance, anticipate better performance from students with certain temperament traits. Some of the
differences between teacher-rated and student-rated temperament
trait associations are in line with such an interpretation, although
this remains speculative, as we did not directly assess how teacher's
opinion on student temperament affects grading. High teacher-rated
activity and negative emotionality were consistently associated with
lower math grades, which is in line with some (Martin, 1989;
Mullola et al., 2010) but not all (Rudasill et al., 2010) previous studies.
By contrast, self-rated negative emotionality, or activity were not
related to math grades, when adjusted for cognitive ability and
motivation. In agreement with these findings, high activity and
high negative emotionality have been related to more negative
teacher-evaluations of student's educational competence, motivation and maturity (Mullola et al., in press). Furthermore, students'
temperament has been shown to be reflected in the attitudes of
the teachers, high activity and distractibility being related to
more negative attitude (Martin et al., 1983).
It should, however, be noted that in Finland, teachers are instructed to evaluate how the student works and regulates his/her
working (which is highly dependent on temperament) and to take
that into account in grade giving. If following these instructions
leads to evaluating temperament instead of evaluating actual learning, the temperament-related bias in grade giving is built in the
evaluation instructions. It may therefore not reflect teachers' own
tendency to confuse evaluations of temperament to that of performance. It should be deliberated whether it is appropriate to include
heritable temperament in criteria for school grades.
Fourth, it is also possible that the direction between temperament assessment and school grades flows the other way around,
so that high-ability students are evaluated more positively by the
teachers. This interpretation is in line with our finding that when
rated by the teachers, all temperament traits were correlated with
cognitive ability test score, whereas when temperament traits
were rated by student these associations were not found, with the
exception of trait persistence. However, we controlled for cognitive
ability, which makes it unlikely that this kind of halo effect would
explain our results.
Self-rated inhibition was positively associated with math grades,
whereas the association was negative, albeit non-significant, for
teacher-assessed inhibition. High inhibition could have a positive
effect on school work because more inhibited children are probably
not as likely to engage in task-irrelevant social activity during
495
lessons as less inhibited children. Moreover, a layman's view of a
mathematically talented person is often characterized by high inhibition. It may be that those good in math form a self-concept
reflecting this view.
High persistence and low distractibility (components of task orientation constellation) were associated with higher grades (similarly as the third component of task orientation, namely low activity
that is discussed above). As mentioned, these relations were independent of the rater of temperament. These results are in line
with previous research that has found consistent associations for
these traits with math performance (Guerin et al., 1994; Martin,
1989; Martin & Holbrook, 1985; Mullola et al., 2010) and between
task orientation and math performance in Scholastic Achievement
Test (Oliver et al., 2007).
In teacher-ratings, a single temperament trait could explain as
much as 7–8% of a math grade even after taking intelligence and
motivation into account. In practice, temperament explains even a
larger proportion because temperament is associated to motivation
(Elliot & Thrash, 2002) which in turn may affect the math grade.
It seems that especially teachers might mix cognitive ability in
their evaluations of temperament, which is visible in the correlations presented in Table 3. Indeed, in teacher-ratings, when motivation and intelligence were not included in the model, temperament
trait explained up to 33% of math grade. The possibility of temperament biasing grade giving should be paid attention to. Student
characteristics may be related to an interaction between a student
and a teacher in many ways: for instance, better learning opportunities may be offered to those with certain characteristics and assessment may be affected as well (Morgan, 2000). It has been
suggested that if reasons for inequitable treatment would be better
understood, it could be more easily avoided (Morgan, 2000). The
possibility that grades are associated with a teacher's subjective
opinion of student temperament unrelated to performance should
be examined.
Moreover, increasing goodness of fit between student temperament and the demands set by school environment is important and
there are many ways for achieving this. For instance, giving students
with high activity possibilities to move might make it easier for
them to adjust. Furthermore, increasing emotional support may be
useful, as classroom emotional support may buffer possible negative
effects of lower temperamental attention on academic performance
(Rudasill et al., 2010). The quality of a teacher–student relationship
may be related to student coping (Ruus et al., 2007) and improvements in it may help all students. Possible ways to improve temperamental fit in schooling has been discussed in detail previously
(Kristal, 2005).
4.1. Limitations and methodological considerations
An important limitation of the current study is the cross-sectional
design, which prevents examining temporal relations. It seems more
likely that temperament would predict math grades than that math
grades would predict temperament: math grades form only a
small part of a person's experiences and temperament has been
shown to be rather stable (Hintsanen et al., 2009; Josefsson et al.,
in press). However, temperament and math grades could be
explained by an unmeasured third factor not included in the current
study. For example, negative life events could be one such factor.
Another limitation is that we could not control for the socioeconomic position of the students. However, taking motivation and ability
test performance into account is likely to compensate for this omission to a large extent, as socioeconomic position is likely to influence school performance through these factors.
TABS-R was originally designed for significantly younger children.
Although the items were altered as more age appropriate for the
current sample, some items may still not be as well suited for
496
M. Hintsanen et al. / Learning and Individual Differences 22 (2012) 490–497
adolescents. In general, the reliabilities of the temperament trait
measures that were used in the current study have been acceptable
expect for self-reported activity. The reliabilities for self-rated persistence and negative emotionality are also in the lower range of acceptable. Therefore, results calculated with self-ratings of these
traits should be viewed cautiously.
It should also be noted that the mathematics grades were selfreported by the students. It has been shown that although selfreported grades reflect actual grades they also include some bias
(Kuncel, Credé, & Thomas, 2005). Therefore, the current results
should be replicated with grades taken from school records.
We are not aware of any other study that would have examined both teacher-ratings and self-ratings of temperament in relation to math grades. Differences in results based on self-ratings
and teacher-ratings were notable and correlations between selfand teacher-ratings of temperament were small to moderate in
size. It is yet unclear, which ratings are the more accurate ones,
or whether there are situational differences in self- and teacherratings. For example, an inhibited student might give a more inhibited impression at school than in more familiar surroundings. Furthermore, teacher-ratings may reflect school achievement whereas
students' self-ratings may to a larger extent reflect views held by
their peers.
TABC-R includes a separate school relevant set of items for
teacher-reports. Therefore, self-ratings and teacher-ratings were
assessed with different items. This could be one explaining factor
for the low correlations between self- and teacher-reported temperaments. However, traits assessed with DOTS-R (mood and distractibility) were assessed with the same items in self- and teacher-reports
and the correlations were not higher than in TABC-R indicating that
differences between self- and teacher-reports are not likely to be
caused by item differences. Furthermore, student–teacher agreement seems to be of similar magnitude in several other areas of
study, such as student social status (Hintsanen et al., 2010), somatic
complaints, delinquent behavior (Grigorenko, Geiser, Slobodskaya, &
Francis, 2010) and internalizing and externalizing problems
(Tompkins, Hockett, Abraibesh, & Witt, 2011).
A strength of the current study is the sample that includes older
participants than those usually examined. The final school years are
especially important as the student's future educational possibilities
depend on them. Furthermore, the sample is larger than in most
previous studies and includes students from several schools and
classes. Furthermore, the analyses were performed with multilevel
modeling, which gives a possibility to take a higher level variance
properly into account unlike more traditional methods which may
lead to biased findings in examining multilevel data.
4.2. Conclusions
The current study shows that high persistence and inhibition
as well as low activity, negative emotionality and distractibility
are associated with better math grades independent of motivation
and cognitive ability. This implies that temperament plays an important role in math grades. This is apparently the first study that
examines both teacher-rated and self-rated temperament in association to math grades taking cognitive ability into account. The raterdependent differences we found are of interest and emphasize the
need for data from multiple raters. Longitudinal research is called
for to clarify the temporal directions of the associations found.
