Recent advances in molecular genetics and epigenetics are reviewed that have major implications for the bio-behavioral sciences and for understanding how organisms adapt to their environments at both phylogenetic and ontogenic levels. From a post-genomics perspective, the environment is as crucial as the DNA sequence for constructing the…

Compared to skilled adult readers, children typically make more fixations that are longer in duration, shorter saccades, and more regressions, thus reading more slowly (Blythe & Joseph, 2011). Recent attempts to understand the reasons for these differences have discovered some similarities (e.g., children and adults target their saccades…

The extreme parenting experiences encountered by children who are physically abused or neglected place them at increased risk for impaired socio-emotional development. There is growing evidence that maltreated children may apprehend interpersonal encounters in different ways from children without such traumatic histories. This systematic review…

The purpose of this paper is to review major statistical and psychometric issues impacting the study of psychophysiological reactivity and discuss their implications for applied developmental researchers. We first cover traditional approaches such as the observed difference score (DS) and the observed residual score (RS), including a review of…

Though often discussed as a discrete event, puberty comprises one segment of a larger developmental continuum and is notable for rapid transformation across a multitude of domains. While an earlier timing of puberty relative to peers stands as one of the most well-replicated antecedents of adolescent difficulties for girls, findings have been less…

Updating a previous systematic review of the literature, this review summarizes the literature over the last 5 years on the relationship between school-based extracurricular activity participation and academic achievement, substance use, sexual activity, psychological adjustment, and delinquency. The review also considers mediators and moderators…

When a witness gives evidence in an adversarial criminal trial, there are two main questioning phases: direct examination and cross-examination. Special provisions are sometimes made for children to give direct evidence, but the majority of child witnesses are still cross-examined. While several decades of research have demonstrated how to elicit…

This is a review of two bodies of research conducted by myself and my colleagues that is relevant to child witness issues, namely childhood amnesia and children's eyewitness memory for stressful events. Although considerable research over the years has investigated the phenomenon of childhood amnesia in adults, only recently has it begun to be…

Young children are often called as witnesses to crimes they were victims of or observed. Because of their immaturity, child witnesses are sometimes more heavily scrutinized than adult witnesses before being allowed to testify in court, for example, through competency screening. This review discusses the psychology and US law relevant to decisions…

There is a long-held assumption that objects help bridge the gap between what children know and what they can (or are willing to) explain. In this review, we present research on the extent to which two types of objects used as props in investigative interviews of children, anatomical dolls and body (human figure) diagrams, actually help children…

Research on factors that can affect the accuracy of children's autobiographical remembering has important implications for understanding the abilities of young witnesses to provide legal testimony. In this article, we review our own recent research on one factor that has much potential to induce errors in children's event recall, namely natural…

Authors have argued that various forms of interventions may be more effective in younger children. Is cognitive training also more effective, the earlier the training is applied? We review evidence suggesting that functional neural networks, including those subserving attentional control, may be more unspecialised and undifferentiated earlier in…

Dual-process theories have become increasingly influential in the psychology of reasoning. Though the distinction they introduced between intuitive and reflective thinking should have strong developmental implications, the developmental approach has rarely been used to refine or test these theories. In this article, I review several contemporary…

Research on the development of planning is reviewed in the context of a framework that considers the role of three types of cognitive flexibility in planning development: event-independent temporal representation, executive function, and self-projection. It is argued that the emergence of planning abilities in the preschool period is dependent…

Overgeneral memory (OGM) is a phenomenon that refers to difficulty retrieving specific autobiographical memories. The tendency to be overgeneral in autobiographical memory recall has been commonly observed among individuals with emotional disorders compared to those without emotional disorders. Despite significant advances in identifying…
