Upon learning the outcome to a problem, people tend to believe that they knew it all along ("hindsight bias"). Here, we report the first study to trace the development of hindsight bias across the life span. One hundred ninety-four participants aged 3 to 95 years completed 3 tasks designed to measure visual and verbal hindsight bias. All age…

Intervention to enhance Interpersonal Cognitive Problem Solving (ICPS) skills has been shown to significantly reduce observable negative, impulsive and inhibited behaviors and increase positive qualities in young, low socioeconomic status (SES) children. An ICPS model for older children was implemented with 202 low SES fifth graders to test…

The role of verbalization in children's mental operations was studied by comparing the mental operations children used in spatial perspective tasks (indicating another's view) and rotation tasks (imagining an object's rotation and one's own subsequent view). Each of 96 children (equal numbers of boys and girls, kindergarten and second grade…

W. M. Gray's "How is Your Logic?" a Piagetian-based, group-administered written test of cognitive development, and B. Leadbeater's Livian Wars Task, a formal operations-based, written, social-cognition problem were given to 348 college undergraduate and graduate students to investigate the impact of chronological age and amount of formal…

Discussion of spatial skills focuses on a quasi-experimental field study that was designed to test the possibility that elementary and secondary school library users' success in stack searches could be related to a particular spatial skill, i.e., the ability to solve large-scale mental-rotation and perspective-taking problems.
