Over the past decade there has been a dramatic increase in referrals to specialty clinics, craniofacial centers, plastic surgeons, and neurosurgeons for assessment and treatment of deformational plagiocephaly (DP). Though considered a medically benign condition, preliminary reports suggest that DP may be associated with developmental problems. However, mechanisms to account for this association...

Evolutionary developmental biology (evo-devo) offers both an account of developmental processes and also new integrative frameworks for analyzing interactions between development and evolution. Biologists and philosophers are keen on evo-devo in part because it appears to offer a comfort zone between, on the one hand, what some take to be the relative inability of mainstream evolutionary biolog...

A developmental-evolutionary perspective is used to synthesize basic research from the neurosciences, ethology, genetics, and developmental psychology into a unified framework for understanding the nature and origins of social anxiety and avoidant personality disorder. Evidence is presented that social anxiety disorder (social phobia) and avoidant personality disorder may be alternate conceptua...

Every year, millions of pounds of toxic chemicals thought to be linked to developmental problems in fetuses and young children are released into the air. In this paper we estimate the effect of these releases on the health of newborns. Using data from the Toxic Release Inventory Program and Vital Statistics Natality and Mortality files, we find significant negative effects of prenatal exposure ...

Numerous studies have established that visual working memory has a limited capacity, and that capacity increases during childhood. However, debate continues over the source of capacity limits and its developmental increase. Simmering (2008) adapted a computational model of spatial cognitive development, the Dynamic Field Theory, to explain not only the source of capacity limitations but also th...

We demonstrate that Drosophila melanogaster provides a rich model system for studying behavioral development. Two additions to the many well-known advantages of this species are exploited here. First, as in mammals and higher vertebrates, early experience affects behavioral development of Drosophila. Second, the affected behaviors are complex and yet readily studied in the laboratory. Thus, Dro...

One of the most replicable findings in psychology is the positive manifold: the observation that individual differences in cognitive abilities are universally positively correlated. Investigating the developmental origin of the positive manifold is crucial to understanding it. In a large longitudinal cohort of adolescents and young adults ( N = 785; n = 566 across two waves, mean interval betwe...

Recent work by Amso and Johnson (Developmental Psychology, 42(6), 1236–1245, 2006) implicates the role of visual selective attention in the development of perceptual completion during early infancy. In the current article, we extend this finding by simulating the performance of 3-month-old infants on a visual search task, using a multi-channel, image-filtering model of early visual processing. ...
