Computer vision algorithms have made tremendous advances in recent years. We now have algorithms that can detect and recognize objects, faces, and even facial actions in still images and video sequences. This is wonderful news for researchers that need to code facial articulations in large data sets of images and videos, because this task is time…

A focal goal of development science in recent years has been to document and understand the psychological processes that underlie inequality toward the goal of promoting equity and justice (e.g., Killen, Rutland, & Yip, 2016). This timely special section on economic inequality broadens the empirical conversation, which has centered mostly on…

I argue that emotion research needs formal (mathematical) theory to address two central questions. How does evolution shape mechanisms of emotion development across generations, depending on environmental conditions? How do these mechanisms generate emotions, based on lifetime experience and current context? Formal modeling enables researchers to…

Future advances in identity research will depend on integration across major theoretical traditions. Developmental-contextualism has established essential criteria to guide this effort, including specifying the context of identity development, its timing over the life course, and its content. This article assesses 4 major traditions of identity…

Despite much research and progress in understanding the development of emotion regulation over the past 3 decades, there is still much to be understood about how developing individuals modulate their affect as they go about their daily life. The papers in this special issue highlight context and dynamics as 2 important intersecting foci for future…

Identity research largely emerged from clinical observations. Decades of empirical work advanced the field in refining existing approaches and adding new approaches. Furthermore, the existence of linkages of identity with psychopathology is now well established. Unfortunately, both the directionality of effects between identity aspects and…

Historically, identity researchers have placed greater emphasis on processes of identity development ("how" people develop their identities) and less on the content of identity ("what" the identity is). The relative neglect of identity content may reflect the lack of a comprehensive framework to guide research. In this article,…

In reviewing this impressive series of articles, I was struck by 2 points in particular: (a) the fact that the empirically oriented articles focused on analyses of data from very large samples, with the articles by Friedman, Kern, Hampson, and Duckworth (2014) and Kern, Hampson, Goldbert, and Friedman (2014) highlighting an approach to merging…

In the present meta-analysis the effects of developmental level on the correlation between simple and complex span tasks were investigated. Simple span-complex span correlation coefficients presented in 52 independent samples (7,060 participants) were regressed on a variable representing mean age of sample (range: 4.96-22.80 years), using analyses…

Dual-process theories have been proposed to explain normative and heuristic responses to reasoning and decision-making problems. Standard unitary and dual-process theories predict that normative responses should increase with age. However, research has focused recently on exceptions to this standard pattern, including developmental increases in…

The transition from general education (e.g., high school) to vocational and tertiary education (e.g., college, vocational school) or to the labor market presents a number of developmental challenges. These challenges include making career choices and, more broadly, managing the transition. Coping with these challenges depends on the individual,…

This commentary traces discussions of psychological differences and deficits from the mid-1950s to the current day, positioning the disciplinary discussions in the social-historical context in which they took place. The challenges of assessing diagnoses of deficit and the potential harms that result when misdiagnosis is implemented as social…

Finding hidden objects in space is a fundamental ability that has received considerable research attention from both a developmental and a comparative perspective. Tracking the rotational displacements of containers and hidden objects is a particularly challenging task. This study investigated the ability of 3-, 5-, 7-, and 9-year-old children and…

Three experiments investigated the ability of seven-month-olds to categorize the facial expressions of happiness, fear, and surprise, which were depicted by degrees of intensity. Happiness could be distinguished in mild and extreme forms, but fear was difficult to discriminate from happiness or surprise. (SKC)

Preverbal infants can represent the causal structure of events, including distinguishing the agentive and receptive roles and categorizing entities according to stable causal dispositions. This study investigated how infants combine these 2 kinds of causal inference. In Experiments 1 and 2, 9.5-month-olds used the position of a human hand or a…
