A critical issue for developmental psychology is how to obtain accurate and complete eyewitness memory reports from preschoolers without offering suggestions that might result in false allegations. We examined effects of two interviewing strategies (police/verbal interviews and clinician/prop-assisted interviews) on young children's reports about…

Investigates effects of age and instructions on temporal regulations of behavior in two experiments. Results of two experiments suggest that for 4 1/2- and 7-year-olds trained with DRL (differential reinforcement of low rates), age and timing performance are related, and that instructions to wait between operant responses enhance DRL performance…

A new method is introduced for assessing children's component selection--i.e., the disposition to attend to a single feature of multifaceted stimuli. (Authors)

Investigated what makes young children acknowledge a false belief held by another person. Showed movies in which a stereotypical item in a familiar box was replaced by one character with an atypical item. Found highly significant improvement in preschoolers' acknowledgment of second character's false belief when preschoolers saw stereotypical…

Monitored the processing activity in the storage and retrieval stages of the information processing sequence. Storage was evaluated by analyses of overt rehearsal; correct responding and order of recall provided data relevant to the retrieval phase. Subjects were third, fifth and seventh graders. (SDH)

Focused on the developmental acquisition of the conditional implication interpretation of "if-then." Knowledge of three aspects of this interpretation was assessed for adults and 3rd-, 5th- and 8th-graders. Results showed the older three groups were significantly more likely to understand conditional implication, with improvement…

It is urged that investigators lay aside demonstrations of the existence of mediation in young children as focus of research, substituting a search for the conditions of its occurrence. (Authors)

The possibility of an age-related increase in the capacity of the short-term store was examined in two experiments, and an "M-operator" model was proposed to account for the data. Together, the two experiments show that an important part of short-term memory development can be explained as growth in short-term store capacity. (Author/MP)

Data indicate that the developmental level of an individual is a significant factor in trace conditioning performance. (Authors)

Investigates the development of evaluative and taxonomic encoding in 7-, to 8-, and 11-year-old children's memories, and related experimental findings to recent work on the development of encoding in memory. (Author/ED)

An investigation of memory development using nonmetric multidimensional scaling. Judgments of similarities between complex objects were obtained from 5-year-olds and adults under two conditions: (1) when objects were simultaneously present at the time of comparison, and (2) when the objects were not simultaneously present and had to be compared on…

Presents evidence supporting claim that sex and gender are important to the explanatory as well as the descriptive goals of developmental psychology. Maintains that studying psychosocial and biological components of gender and sex helps one to develop hypotheses about causal mechanisms for developmental outcomes more generally. Introduces the…
