Professional computer programmers' mental representations of computer programs were studied. In two experiments, subjects were tested on comprehension and recognition, or asked to modify a program. The influence of procedural relations (control flow) was more dominant than the influence of functional relations (goal hierarchy). (GDC)

Five experiments investigated how completely and accurately adults remember the visual details of the common United States penny. Subjects had to draw a penny from unaided recall and select the correct representation of a penny. Performance was poor on all tasks. Implications for long-term memory models were discussed.

In 5 experiments involving 306 adults, the mechanisms underlying semantic priming in the domain of face recognition, particularly famous faces, and the plausibility of modularity were assessed. Results suggest that sensitivity changes that occur when direct associative connections within the module can be ruled out pose a problem for modularity.…

Four experiments examined the flexibility and stability with which children and adults organize locations into categories based on their spatiotemporal experience with locations. Seven-, 9-, 11-year-olds, and adults learned the locations of 20 objects in an open, square box. During learning, participants experienced the locations in four…
