We present an exact replication of Experiment 2 from Kovács and Mehler's 2009 study, which showed that 7-month-old infants who are raised bilingually exhibit a cognitive advantage. In the experiment, a sound cue, following an AAB or ABB pattern, predicted the appearance of a visual stimulus on the screen. The stimulus appeared on one side of the…

The study of children's prospective memory has gained new momentum over the past 20 years and is now an active area of research in cognitive development. Yet, this resurgence has been accompanied by significant challenges that offer important lessons and insights for other areas of developmental science. In this article, I provide an overview and…

These studies investigate the influence of adults' explicit attention to commonalities of appearance on children's preference for individuals resembling themselves. Three findings emerged: (1) An adult's identification of two dolls' respective similarity to and difference from the child led 3-year-olds to prefer the similar doll (study 1, n = 32).…

Remembering to carry out intended actions in the future, known as prospective memory (PM), is an important cognitive ability. In daily life, individuals remember to perform future tasks that might rely on effortful processes (monitoring) but also habitual tasks that might rely on more automatic processes. The development of PM across childhood in…

We investigated the kinds of biological properties that children aged 3-6 years attribute to animals, plants, and artifacts by administering a property attribution task and eliciting explanations for the resulting property attributions. Findings indicated that, from the age of 3 years, children more frequently attribute properties to animals than…

The quality of early caregiving and educational environments has a significant effect on children's later cognitive outcomes. Early childhood teachers are an important determining factor in the quality of these environments and therefore they need appropriate professional preparation. The purpose of this study was to describe the ways in which…

Being able to see a talking face confers a considerable advantage for speech perception in adulthood. However, behavioural data currently suggest that children fail to make full use of these available visual speech cues until age 8 or 9. This is particularly surprising given the potential utility of multiple informational cues during language…

The field of developmental psychology has produced abundant theory and research about the physical, cognitive, social, and emotional development of children; however, to date there has been limited use of this wealth of knowledge by developers creating games for children. This chapter provides an overview of key theoretical observations and…

The present study aims to investigate the interplay of verbal and nonverbal communication with respect to infants' perception of pointing gestures. Infants were presented with still images of pointing hands (cue) in combination with an acoustic stimulus. The communicative content of this acoustic stimulus was varied from being human and…

Human adults will sometimes help without being asked to help, including in situations in which the helpee is oblivious to the problem and thus provides no communicative or behavioral cues that intervention is necessary. Some theoretical models argue that these acts of "proactive helping" are an important and possibly human-specific form of…

It is well established that 2-year-olds attribute a novel label to an object's global shape rather than local features (i.e., parts). Although recent studies have found that younger infants also attend to global rather than local features when given a label, the test stimuli in these experiments confounded parts and shape by varying both or…

Children growing up in a dual-language environment have to constantly monitor the dynamic communicative context to determine what the speaker is trying to say and how to respond appropriately. Such self-generated efforts to monitor speakers' communicative needs may heighten children's sensitivity to, and allow them to make better use of,…

Two studies examined how children between ages 4 and 6 use body shape (i.e., the waist-to-hip-ratio [WHR]) for sex categorization. In Study 1 (N = 73), 5- and 6-year-olds, but not 4-year-olds, selected bodies with increasingly discrepant WHRs to be "most like a man" and "most like a woman." Similarly, sex category judgments made by 5- and…

Body language and facial gesture provide sufficient visual information to support high-level social inferences from "thin slices" of behavior. Given short movies of nonverbal behavior, adults make reliable judgments in a large number of tasks. Here we find that the high precision of adults' nonverbal social perception depends on the slow…

This study explored the criteria that children and adults use when evaluating the niceness of a character who is distributing resources. Four- and five-year-olds played the "Giving Game", in which two puppets with different amounts of chips each gave some portion of these chips to the children. Adults played an analogous task that mimicked the…
