This study examined 6- to 8-year-old Slovenian children's acquisition of matrix completion proficiency and compared microgenetic and age-related changes on the task. Microgenetic analyses indicated that: variability of children's errors increased before they discovered the correct strategy, the correct strategy became dominant shortly after…

Two studies examined 6- to 11-year-olds' gender-related interpretations of occupational titles. Findings indicated that children were sensitive to linguistic forms of job titles, and that these sensitivities differed in relation to participant variables such as attitude. Gender-specific interpretations occurred more frequently for marked…

Four experiments studied effects of difficulty of word identification on optional conceptual processing by second, third, and fifth graders, and college students in a cued recall task. Results indicated that contrastive processing facilitates recall, and that difficulty of word identification may limit the extent of optional contrastive…

Five studies examined the contributions of syllable-ordering and rhythmic properties of syllable strings to 6- and 9-month-old infants' speech segmentation. Results indicate that the capacity for integrating multiple sources of information in speech perception emerges between 6 and 9 months, in rough synchrony with the emergence of integration in…

Examines the use of tasks with backward false belief explanation as an effective technique in gaining a complete picture of the development of understanding of the representational mind. Argues that traditional prediction tests of false belief cannot tell whether children's wrong answers show misunderstanding about false belief or seduction by the…

Six-month-old African-American infants' expectation of a visual stimulus was related to developmental measures. Reaction time was related to eye fixation in tests that measured visual recognition memory (VRM) and presented objects of different shapes to the infant. Reaction time and infants' stimulus expectation predicted VRM novelty preference.…

Examined degree to which analytic and holistic modes of processing play a role in children's and adults' categorization of faces. Found a developmental trend from analytic to holistic processing and an effect of face inversion with increasing age. Seven-year-olds processed faces comparably to nonfacial visual stimuli, whereas a growing proportion…

Two studies were conducted to investigate the specificity of the relationship between preschoolers' emerging executive functioning skills and false belief understanding. Study 1 (N=44) showed that 3- to 5-year-olds' performance on an executive functioning task that required selective suppression of actions predicted performance on false belief…

This study assessed the relation between mother mental state language and child desire language and emotion understanding in 15--24-month-olds. At both times point, mothers described pictures to their infants and mother talk was coded for mental and nonmental state language. Children were administered 2 emotion understanding tasks and their mental…

The hypothesized central role of cognitive development in resolving moral dilemmas was examined in sixth grade and college-age females. Results indicated that sophisticated cognitive operations are a prerequisite to advanced moral judgments. (ST)

First, second, third, sixth, and ninth graders and college students were presented with 4 different tasks of surface-volume dissociation in order to see whether or not the conservation of one of these properties would wrongly induce a belief in the conservation of the other. (Author/JMB)

Concerns the development of children's understanding of representational change and its relation to other cognitive developments. Two experiments involve day care children, aged three, four, and five years. Results suggest that children begin to consider alternative representations of the same object at about age four.

Investigates ability of nine-month-old infants to imitate simple actions with novel objects. Looks at both immediate and deferred imitation. Findings show that imitation in early infancy can span wide enough delays to be of potential service in social development. (Author/RWB)

Tests two hypotheses concerning developmental change in the speed of cognitive processes: (1) age differences in processing time reflect changes that are specific to particular tasks, and (2) age differences in processing speed do not reflect task-specific change but are due instead to more general developmental change. (HOD)

Reports the use of a memory load-interference paradigm and the easy-to-hard paradigm as converging operations to study capacity limitations in five- to six-year-old's reasoning. Concludes that transitive inference ability in children is capacity limited. (HOD)
