We tested whether changes in attribution processes could account for the developmental differences observed in how children's use fluency to guide their memory decisions. Children ranging in age from 4 to 9 years studied a list of familiar or unfamiliar cartoon characters. In Experiment 1 (n = 84), participants completed a recognition test during…

Children rely on both evidence and prior knowledge to make physical causal inferences; this study explores whether they make attributions about others' behavior in the same manner. A total of one hundred and fifty-nine 4- and 6-year-olds saw 2 dolls interacting with 2 activities, and explained the dolls' actions. In the person condition, each doll…

To what extent do children understand that biological processes fall into 1 coherent domain unified by distinct causal principles? In Experiments 1 and 2 (N = 125) kindergartners are given triads of biological and psychological processes and asked to identify which 2 members of the triad belong together. Results show that 5-year-olds correctly…

This longitudinal study tested the veracity of one candidate multiple-deficits account of autism by assessing 37 children with autism (M age = 67.9 months) and 31 typical children (M age = 65.2 months) on tasks tapping components of theory of mind (ToM), executive function (EF), and central coherence (CC) at intake and again 3 years later. As a…

Recent research has shown that infants as young as 13 months can attribute false beliefs to agents, suggesting that the psychological-reasoning subsystem necessary for attributing reality-incongruent informational states (Subsystem-2, SS2) is operational in infancy. The present research asked whether 18-month-olds' false-belief reasoning extends…

The study was to determine when the patterns of causal evidence proposed by Orvis, Cunningham and Kelly (1975) begin to function as schemata in the attributional process. One hundred forty-four subjects took part in the study. (RH)

This study examined the general importance of similarity in children's causal reasoning and the relation between similarity and the other principles of causal inference. Participants were 16 boys and 16 girls at each of four grade levels: K, 2, 4, and 6. (Author/JMB)

Investigated children's causal-explanatory conceptions of the workings of a labeling strategy. The 72 children of four-six years showed two types of conceptions, both of which increased with age. (RJC)

The hypothesis that, when trying to decide whether the person, stimulus, or circumstance is the cause of an event, individuals increasingly select schema-consistent information with increasing age was tested in 106 Turkish 9-, 12-, and 17-year-old subjects. (Author/RH)

A study showed that 5- to 15-year-old children first employed Heider's commission rule, then his intentionality rule, and finally the foreseeability rule at about 11 years of age. Results suggest that both the Heider and Piaget attribution research traditions were correct in part. (RH)

Examines developmental change in 4- 7- and 10-month-old infants' perceptions of correlations among attributes to determine whether relational information plays a role in abilities ranging from the perception and recognition of a simple pattern to the formation of a category. (HOD)

Examined whether aggressive boys' hostile attribution bias extends to processing incoming information. Subjects were asked to segment videotaped actions based on information conditions about the two boys playing in the film. Aggressiveness predicted change in segmentation after the critical event only in the neutral prior-information condition,…

Examines the implications of temporal separation for children's developmental differences in inferences drawn about an individual's characteristics after observing multiple instances of that individual's behavior. Also tests two competing hypotheses about how young children process information separated in time. (HOD)

Children's magical explanations and beliefs were investigated in two studies. Found that many four-year olds view magic as a plausible mechanism, yet reserve magical explanations for certain real world events that violate their causal expectations. Parents and culture at large may at first actively support magical beliefs whereas peers and schools…
