Observers experience complex patterns of visual motion in daily life due to their own movements through space, the movement of objects, and the geometry of surfaces in the visible world. Motion information shapes behavior and brain activity beginning in infancy. And yet most prior behavioral research has focused on how children process only one…

Previous research has shown that when learning categories, adults and young children allocate attention differently. Adults tend to attend selectively, focusing primarily on the most relevant information, whereas young children tend to distribute their attention broadly. Although selective attention is useful in many situations, it also has costs.…

There is general consensus that the representation of the human face becomes functionally specialized within the first few months of an infant's life. The literature is divided, however, on the question whether the specialized representation of the remainder of the human body form follows a similarly rapid trajectory or emerges more slowly and in…

Younger children have more difficulty in sharing attention between two concurrent tasks than do older participants, but in addition to this developmental change, we documented changes in the nature of attention sharing. We studied children 6-8 and 10-14 years old and college students (in all, 104 women and 76 men; 3% Hispanic, 3% Black or African…

Understanding gender differences in human cognitive development may contribute to understanding the gender differences in outcomes in cognitive ageing. However, evaluation of this topic has been hindered by a lack of representative, longitudinal data from different aged cohorts measured on the same cognitive tests. Gender differences in cognitive…

Developmental delays in cognitive flexibility early in elementary school can potentially increase vulnerability for subsequent externalizing and internalizing psychopathology. The first goal of the current study was to identify latent subgroups of children characterized by different developmental trajectories of cognitive flexibility throughout…

This research examined how 5-, 8-, and 11-month-olds with female primary caregivers mentally represented faces using a familiarization procedure similar to real-world experience in which infants have greater exposure to female faces aged 21-39 years than other face types. We predicted infants would form weighted representations of faces (i.e.,…

Categories are fundamental to everyday life and the ability to learn new categories is relevant across the lifespan. Categories are ubiquitous across modalities, supporting complex processes such as object recognition and speech perception. Prior work has proposed that different categories may engage learning systems with unique developmental…

Children's early environmental experiences are often considered highly influential for later life development. Yet, environmental contexts, such as the home and early care and education (ECE) setting, and multiple aspects of each setting, are not typically examined concurrently. In this study, we examined associations between cognitive stimulation…

The ability to bind, or link, different aspects of an experience in memory undergoes protracted development across childhood. Most studies of memory binding development have assessed extraobject binding between an object and some external element such as another object, whereas little work has examined the development of intraobject binding, such…

We examined the developmental trajectories and cognitive predictors of first language Chinese reading, second language English reading, and mathematics skills in Hong Kong children in Grades 1-5. We used longitudinal data of 1,000 children (M[subscript age] = 7.59 years) assessed on phonological awareness, rapid naming, and morphological awareness…

The age-related positivity effect--a preference for processing positive stimuli over negative stimuli--is posited by socioemotional selectivity theory to reflect a focus on emotional gratification in older age. Yet, the positivity effect has been investigated with stimuli, such as photographs of faces and visual scenes, that have little (to no)…

Infants' ability to perform visual short-term memory (VSTM) tasks develops rapidly between 6 and 8 months. Here we tested the hypothesis that infants' VSTM performance is influenced by their ability to individuate simultaneously presented objects. We used a "one-shot change detection task" to ask whether 6-month-old infants (N = 47)…

It is often argued that metacognition includes 2 components: monitoring and control. However, it is unclear whether these components can operate independently, or whether they always operate as part of a hierarchy. The current study attempts to address this issue. In Experiment 1 (N = 90), age-related differences were assessed to examine the…

Recent research found no evidence that children aged 7-10 years are able to direct their attention to more valuable information in working memory. The current experiments examined whether children demonstrate this ability when the reward system used to motivate participants is engaging and age-appropriate. This was explored across different memory…
