Imagination inflation: Imagining a childhood event inflates confidence that it occurred

Counterfactual imaginings are known to have far-reaching implications. In the present experiment, we ask if imagining events from one’s past can affect memory for childhood events. We draw on the social psychology literature showing that imagining a future event increases the subjective likelihood that the event will occur. The concepts of cognitive availability and the source-monitoring framework provide reasons to expect that imagination may inflate confidence that a childhood event occurred. However, people routinely produce myriad counterfactual imaginings (i.e., daydreams and fantasies) but usually do not confuse them with past experiences. To determine the effects of imagining a childhood event, we pretested subjects on how confident they were that a number of childhood events had happened, asked them to imagine some of those events, and then gathered new confidence measures. For each of the target items, imagination inflated confidence that the event had occurred in childhood. We discuss implications for situations in which imagination is used as an aid in searching for presumably lost memories.     

Word association and the acquisition of reading

Two studies relating reading ability to word association responses were carried out. The first involved early readers and matched control children from pre-first-grade classes. There were 29 early readers and 29 nonreading controls matched for age, sex, and IQ. The early readers were found to give significantly more paradigmatic, or same-form-class, responses than the controls. The second study related reading ability, mental age, and word association responses in developmentally delayed teen-agers and young adults, and pre-first-grade children who varied in reading ability. With partial correlation reading ability was found to be related to paradigmatic responding, while mental age was not significantly related. These results indicate that reading acquisition may change word association responses in children through a reorganizing process in the lexicon.The authors would like to thank the Halifax and Dartmouth School Boards for their cooperation. We would also like to thank Paul Cable of Special Education, and the principals and teachers: Beth Conrad, Karen Duerdan, Elaine Fram, Peter Montgomery, Wayne Serebrin, and Bill Schipilow. Their help was greatly appreciated. An earlier version of study 1 was presented at the American Psychological Association meeting in Los Angeles, August 1981.     

The Kitty Genovese murder and the social psychology of helping: the parable of the 38 witnesses

This article argues that an iconic event in the history of helping research -- the story of the 38 witnesses who remained inactive during the murder of Kitty Genovese -- is not supported by the available evidence. Using archive material, the authors show that there is no evidence for the presence of 38 witnesses, or that witnesses observed the murder, or that witnesses remained inactive. Drawing a distinction between the robust bystander research tradition and the story of the 38 witnesses, the authors explore the consequences of the story for the discipline of psychology. They argue that the story itself plays a key role in psychology textbooks. They also suggest that the story marks a new way of conceptualizing the dangers of immersion in social groups. Finally, they suggest that the story itself has become a modern parable, the telling of which has served to limit the scope of inquiry into emergency helping.     

A Novel Approach to Enhancing Upper Extremity Coordination in Children with Autism Spectrum Disorder

Abstract

Recent studies examining children diagnosed with Autism Spectrum Disorder (ASD) have revealed kinematic markers highlighting deficits in the preparatory and online phases of upper extremity movements. In the following study, 12 children with high functioning ASD were first assessed (pre-test) on 15 trials of a reciprocal upper extremity Fitts Law target task by flexing and extending their right arm in the horizontal plane between two targets as fast and accurately as possible. Following the initial assessment, the children either continued with 30 additional trials of the target task (control) or were asked to track a sine wave template (experimental). All participants were then assessed on 15 trials of the target test (post-test). Results reveal that tracking the sine wave template during training not only produced faster movements compared to the control but also produced these movements in a more harmonic way.     

Reflex eyeblinks and visual suppression

Voluntary blinks are known to be accompanied by visual suppression that arises, at least in part, through nonretinal processes. We wanted to test the hypothesis that this suppression must arise as a corollary to the voluntary command to blink. We therefore examined visual sensitivity at the time of a blink that does not involve a voluntary command, namely the corneal reflex elicited by a puff of air. We found that sensitivity was reduced during these reflex blinks; the magnitude and time course of suppression were similar to those of voluntary blinks. We therefore adopt the view that visual suppression stems from signals from the common, efferent, blink pathway.     

Interparental violence, maternal emotional unavailability and children's cortisol functioning in family contexts

Our goal in the present study was to examine the specificity of pathways among interparental violence, maternal emotional unavailability, and children's cortisol reactivity to emotional stressors within interparental and parent-child relationships. The study also tested whether detrimental family contexts were associated, on average, with hypocortisolism or hypercortisolism responses to stressful family interactions in young children. Participants included 201 toddlers and their mothers who were from impoverished backgrounds and who experienced disproportionate levels of family violence. Assessments of interparental violence were derived from maternal surveys and interviews, whereas maternal emotional unavailability was assessed through maternal reports and observer ratings of caregiving. Salivary cortisol levels were sampled at 3 time points before and after laboratory paradigms designed to elicit children's reactivity to stressful interparental and parent-child contexts. Results indicated that interparental violence and the mother's emotional unavailability were differentially associated with children's adrenocorticol stress reactivity. Furthermore, these family risk contexts predicted lower cortisol change in response to distress. The results are interpreted in the context of risky family and emotional security theory conceptualizations that underscore how family contexts differentially impact children's physiological regulatory capacities.
