Body language and facial gesture provide sufficient visual information to support high-level social inferences from "thin slices" of behavior. Given short movies of nonverbal behavior, adults make reliable judgments in a large number of tasks. Here we find that the high precision of adults' nonverbal social perception depends on the slow…

Developmental studies have provided mixed evidence with regard to the question of whether children consider sample size and sample diversity in their inductive generalizations. Results from four experiments with 105 undergraduates, 105 school-age children (M = 7.2 years), and 105 preschoolers (M = 4.9 years) showed that preschoolers made a higher…

Two experiments examined developmental patterns in children's conditional reasoning with everyday causal conditionals. In Experiment 1, a group of pre-, early, young, and late adolescents generated counterexamples for a set of conditionals to validate developmental claims about the counterexample retrieval capacity. In Experiment 2, participants…

Two studies examined developmental patterns in understanding physical and social transitivity in 6- to 11-year olds. Findings revealed no significant correlations between social judgments and judgments concerning length. Results suggested that children possess two distinct strategies for making transitive judgments that correspond to the logical…

Examined whether developmental differences exist in availability of inferences during listening comprehension. Presented child and adult subjects with consistent and inconsistent passages to determine outcome of expected and unexpected messages on memory. Found that children were more likely than adults to retain incorrect information in active…

Used single-subject analyses to examine the developmental difficulty of the ulterior motive question (the backward inverse inference) in five- and seven-year-olds. Results suggest that children's difficulties with ulterior motive information result both from the abstract nature and the logical form of the task. (Author/SKC)

Four studies examined the tendency of preschoolers to use verbal labels versus appearance information in making novel inductive inferences. Results revealed that preschoolers tended to use trait labels of "shy" or "outgoing" rather than superficial resemblance in making psychological inferences. These results could not be attributed to biases on…

Five experiments were used to determine whether and why second graders, fourth graders, and college students differ in modifying causal inferences about a surprising event in a story. Illustrated how encoding and retrieval factors contribute to inference modification. Results showed small developmental increases in inference modification in…

Describes three experiments that examined how children (4- to 11-year-olds) use their knowledge of the attributes of living things to infer whether particular objects are alive. (HOD)

Used the confirmability model a method for assessing individuals' perceptions of other persons, to study developmental differences in the amount of information children and adults require to infer various traits. Found differences in the amount of information required to infer different traits and evidence of subjects' negativity and egocentric…

Four experiments examined the possibility that second and fourth graders and college students are sensitive to inference constraint when they make causal inferences and assess their understanding of a story. Inference likelihood and understanding ratings varied with constraint for all ages. Results suggest that comprehension monitoring and text…
