The authors evaluated evidence from existing spontaneous production, elicited production, and grammaticality judgment studies of finiteness in child Spanish. They measured the relationship of 7 spontaneous speech measures with previous receptive and expressive measures of finiteness and performed a discriminant function analysis, using tense as the target variable, to classify monolingual child Spanish (n = 55) as representing SLI or as typically developing (TD). Spontaneous speech measures correlated with the results of previous receptive and expressive measures of child Spanish that show a tense deficit. The SLI group was shown to have statistically lower scores than the TD group on 6 of 7 spontaneous speech measures. Multiple discriminant functions, including tense measures by themselves and in combination with spontaneous speech measures, were shown to provide fair to good sensitivity and specificity in the classification of children as having SLI vs. TD. The findings support the contention that the tense-marking deficit is a plausible clinical marker of SLI for Spanish-speaking children.

Twenty-two patients attending with antecedent of thinner abuse only, and twenty two controls without alcohol, smoking, and drug abuse in the same age range and gender were studied. EEG recording were compared by means of the analyses of peak of frequency (POF), frequency of disorganization, and asymmetry of the background activity in patients and controls at rest eyes-closed condition in electrodes P3, P4, O1, and O2. Significant differences in POF among groups was observed in P3 and P4 location showing lower values in thinner abusers, but not in O1 and O2 locations. Frequencies of disorganization and asymmetry showed significantly higher proportions in thinner abusers. Bivariate correlations among POF at the four electrode location and time of thinner abuse showed significant values. However after partial correlation calculation correcting for age, significant values disappeared. Thus thinner abuse relates with slowing of POF in the EEG of patients with thinner abuse associated with disorganization, and asymmetry depending on time of abuse.
