Children witnessed the hiding of a small toy in a scale model of a room and were then required to search for an analogous larger toy that had been surreptitiously hidden in the actual room. At issue was whether children succeed by attending to the target location (object strategy), to the spatial location of the target location (spatial strategy), or to both types of information. It has been suggested that at three years of age (the age at which children first succeed on the task) children succeed by recognizing the correspondence between analogous objects in the two spaces (Bence & Presson, 1997; Blades & Cooke, 1994; Perner, 1991; Lillard, 1993) but that an understanding of the model as a whole as a representation of the room necessitates also attending to the spatial relations between the objects (Perner, 1991; Lillard, 1993). In five Experiments, children partici...

Its development in the preschool years is rapid and also malleable. Thus, preschool curricula that promote the development of self-regulation may help set children on a more positive developmental trajectory. We conducted a cluster-randomized controlled trial of the Tools of the Mind preschool curriculum, a program that targets self-regulation through imaginative play and self-regulatory language (Tools; clinical trials identifier NCT02462733). Previous research with Tools is limited, with mixed evidence of its effectiveness. Moreover, it is unclear whether it would benefit all preschoolers or primarily those with poorly developed cognitive capacities (e.g., language, executive function, attention). The study goals were to ascertain whether the Tools program leads to greater gains in self-regulation compared to Playing to Learn (YMCA PTL), another play based program that does not tar...

In 3 studies, we investigated the challenges underlying this difficulty in kindergarten and second grade by comparing performance on different versions of a linear measurement task. Children measured crayons that were either aligned or shifted relative to the left edge of either a continuous ruler or a row of discrete units. The alignment (aligned, shifted) and the measuring tool (ruler, discrete units) were crossed to form 4 types of problems. Study 1 showed good performance in both grades on both types of aligned problems as well as on the shifted problems with discrete units. In contrast, performance was at chance on the shifted ruler problems. Study 2 showed that performance on shifted discrete unit problems declined when numbers were placed on the units, particularly for kindergarteners, suggesting that on the shifted ruler problems, the pres...

Alliance was rated near the end of the first month of treatment. At pre-, mid- and posttreatment, maternal depression and adolescents' externalizing behavior were assessed via mother reports, and by clinicians at pre- and posttreatment only. Mediational analyses showed that therapist-rated alliance was related to improvements in maternal depression, which, in turn, was associated with reductions in adolescent externalizing behavior as rated by mothers. There was no association between mothers' and therapists' perceptions of the therapeutic alliance.
