Three experiments examined 5- to 8-year-olds' ability to make tentative interpretations of ambiguous messages. It was concluded that although 5- and 6-year-olds' interpretations of ambiguous messages were not tentative at the outset, they were able to use source monitoring skills to treat them as tentative retrospectively, at least over short time…

Two experiments were conducted to investigate age-related differences in visual search for targets defined by the conjunction of two features. In the experiments, 7- and 10-year-old children and young adults searched visual displays for a black circle among distractors consisting of gray circles and black squares. In Experiment 1 (N=60), we…

To examine the development of look duration as a function of age and stimulus type, 14- to 52-week-old infants were shown static and dynamic versions of faces, Sesame Street material, and achromatic patterns for 20 s of accumulated looking. Heart rate was recorded during looking and parsed into stimulus orienting, sustained attention, and…

This article addresses a question that was a topic of debate in the middle decades of the 20th century but was then abandoned as interest in children's learning declined. The question is, does learning develop? In other words, does the learning process itself undergo age-related change, or does it remain invariant ontogenetically and…

Relational similarity connects superficially dissimilar objects and events. In 2 experiments, the ability to recognize and respond to similar relations was studied in children ages 3 to 5 with 2 comparison tasks. Children interpreted illustrated pictures that shared perceptual or relational aspects and then made 2 comparison choices and…

What lies behind the lack of theorizing about content in history in contrast to much greater attention given to theorizing about children's developing understanding of historical skills and processes? Egan's model of the characteristic ways in which children of different ages engage with the world is used to raise the question of what content to…

In the standard Iowa Gambling Task (IGT), participants have to choose repeatedly from four options. Each option is characterized by a constant gain, and by the frequency and amount of a probabilistic loss. Crone and van der Molen (2004) reported that school-aged children and even adolescents show marked deficits in IGT performance. In this study,…

Learning names for parts of objects can be challenging for children, as it requires overcoming their tendency to name whole objects. We test whether comparing items can facilitate learning names for their parts. Applying the structure-mapping theory of comparison leads to two predictions: (a) young children will find it easier to identify a common…

This study explored the impact of infant-directed speech (IDS) versus adult-directed speech (ADS) on neural activity to familiar and unfamiliar words in 6- and 13-month-old infants. Event-related potentials were recorded while infants listened to familiar words in IDS, familiar words in ADS, unfamiliar words in IDS, and unfamiliar words in ADS.…

Three experiments investigated whether children in grades K, 2, and 4 (n = 144) view emotional comprehension as important in solving moral dilemmas. The experiments asked whether a human or an artificially intelligent machine would be best at solving different types of problems, ranging from moral and emotional to nonmoral and pragmatic. In…

It has been suggested that older adults are more variable in their performance because they are more prone to lapses of either attention or intention. In the present experiment, 9 young and 9 older adults each performed nearly 2,000 trials of a same-different judgment task. As expected, older adults were slower and more variable than young adults.…

Objective: Past investigations indicate facial emotion-processing abnormalities in pediatric bipolar disorder (PBD) subjects. However, the extent to which these deficits represent state- and trait-related factors is unclear. We investigated facial affect processing in acutely ill and clinically stabilized children with PBD and matched healthy…

Over the past decade, a number of well-controlled studies have supported the validity of a cognitive model of generalized anxiety disorder (GAD) that has four main components: intolerance of uncertainty, positive beliefs about worry, negative problem orientation, and cognitive avoidance. Although these studies have shown that the model components…

The research study investigated the memory and metamemory abilities of four severely to profoundly deaf students with bilateral sensory-neural loss, between the ages of 9 and 20 years. Metamemory was investigated with four modified subtests identified as "story list,""study plan,""retrieval event," and "opposites-arbitrary." Encoding was…

Investigates whether age differences in memory span are affected by type of material, with the aim of making inferences about capacity. Subjects were 30 boys and girls from each of three elementary school grade levels (first, third and sixth). (Author/MP)
