The aim of the present study was to explore how maternal reminiscing relates to socioemotional development during middle childhood. Specifically, analyses explored the link between maternal reminiscing and children's internalizing (emotional problems and peer problems), externalizing (hyperactivity and conduct problems) and prosocial behavior…

Scientific reasoning refers to the thinking skills involved in conceiving and conducting an investigation. This study examined how proficiency in performing these skills develops during the upper-elementary school years. A sample of 157 children (age 7-10) took a performance-based scientific reasoning test in three consecutive years. Four distinct…

Research suggests that individual differences in math abilities correlate with approximate representations of quantity that are supported by a primitive Approximate Number System (ANS). However, relatively little research has addressed the direction of this association in early childhood. Here we examined the development of the ANS and math…

The study of executive function (EF) has become increasingly popular in multiple areas of research. A wealth of evidence has supported the value of EF in shaping notable outcomes across typical and atypical development; however, little evidence has supported the cognitive contributors to early EF development. The current study used data from a…

Data from a large-scale, longitudinal research study with an ethnically and socioeconomically diverse sample were utilized to explore linkages between maternal elaborative conversational style and the development of children's autobiographical and deliberate memory. Assessments were made when the children were aged 3, 5, and 6 years old, and the…

Longitudinal data analysis has long played a significant role in empirical research within the developmental sciences. The past decade has given rise to a host of new and exciting analytic methods for studying between-person differences in within-person change. These methods are broadly organized under the term "growth curve models." The…

We examined how maternal strategic behaviors during a mother-child collaborative sort-recall task of categorically similar items related to children's recall and children's strategic behavior in a sort-recall task that they completed independently. Mother-child dyads participated in the collaborative sort-recall task when children were 40 months…

We longitudinally investigated the development of endogenous control of attention in 2 types of tasks that involve competition for attentional focus at 7, 9, and 31 months of age. At all 3 sessions, children participated in a multiple object free play task and a distractibility task. The results revealed both developmental differences and…

As children develop, they process information more rapidly. The primary aim of this study was to determine whether processing speed in the language domain develops at the same rate as global processing speed. A second aim was to determine the stability of processing speed throughout childhood and adolescence. Children (N = 116) were tested on 10…
