Children prenatally exposed to opioids exhibit impairments in cognitive functioning and have an increased likelihood of experiencing other forms of adversity. Given that these other forms of early life adversity are linked to lower levels of cognitive functioning, it is important to determine whether the association between opioid exposure and…

Given the substantial increase in children attending center-based childcare over the past decades, the consequences of center-based childcare for children's development have gained more attention in developmental research. However, the relation between center-based childcare and children's neurocognitive development remains relatively…

When presented with a claim that contradicts their intuitions, do children seize opportunities to empirically verify such claims or do they simply acquiesce to what they have been told? To answer this question, we conducted a replication of Ronfard et al. (conducted in the People's Republic of China) in two countries with distinct religious and…

This study establishes a sequence of developing mental state understandings in infants. We used three violation-of-expectation paradigms to assess fifty-seven 16-month-olds' ability to (a) infer an actress's intention from her prior repeated approaches to an object, (b) recognize her emotion by watching her facial-emotional display, and (c) deduce…

Two studies are presented to examine whether and why 3-5-year-olds in Pakistan display limited social understanding. Study 1 tested 71 preschoolers on Lillard and Flavell's (1992) test of desires, pretence and beliefs, plus two false belief tasks, and showed very limited understanding across these measures even though almost half were over 5 years…

The development of emotion understanding in young Chinese preschoolers was examined. The overall developmental trend, as measured by the Test of Emotion Comprehension (TEC), proved similar to that found among preschoolers in Western Europe. However, Chinese children performed better at understanding the distinction between real and apparent…

We investigated the role of mothers' references to mental states and behaviors and children's emotion situation knowledge (ESK) in a prospective, cross-cultural context. European American mothers (n = 71) and Chinese immigrant mothers (n = 60) and their children participated in the study. Maternal references to mental states and behaviors were…

There are few studies of behavior problems in preterm children prior to 2 years old and the changes that occur over time. The aims of this study were to examine the patterns and prediction of behavior problems and the effects of gender and socioeconomic status (SES) on behavior problems in preterm children at the toddler and preschool periods.…

We investigated the ability to detect a face among other visual objects in a complex visual array in 3-, 4-, and 5-year-old children, as well as in adults. To this end, we used a visual search paradigm implemented on a touch-tablet device. Subjects (N = 100) saw up to eighty 3 × 3 visual search arrays and had to find and tap upon a target--a face…

This study investigated cross-cultural variation in the development of executive functioning (EF) across the preschool period for United States and Chinese children from low and high socioeconomic families using a longitudinal design. Participants included 216 preschool children (n = 125 from the US; n = 91 from Shanghai and Jiangxi, China). On…

This article documents differences in cognitive development, as measured by the Peabody Picture Vocabulary Test (PPVT), between children from households with high and low socioeconomic status (SES) in two different phases of early childhood in four developing countries. A large number of potential mediators, such as urban residence, preschool…

Two experiments were conducted to compare the false belief understanding of children who have no siblings, but have classmates of different ages in kindergarten. In Experiment 1, 4- and 5-year-olds completed two unexpected location tasks. We found that 4-year-olds with classmates of different ages performed significantly better than those with…

There are many postulates of a relation between quality of attachment with theory of mind and language functions (e.g., de Rosnay & Hughes, 2006). The current study examined in longitudinal design how different patterns of attachment are associated with usage of internal state language at ages 17, 23, 30 and 36 months. Transcripts of mother-child…

Longitudinal data gathered on 24 children at 51 months of age and at earlier ages suggest that children currently characterized as faster habituators, in terms of first fixation data, may be somewhat advanced cognitively compared to slower habituators. (Author/DB)

Describes research on memory in preschool children. Each child was studied for scene and list memory. Domain-specific and general knowledge were not found to be strongly related to memory performance. Object typicality did not have a strong effect on memory, but size did. (GH)
