We investigated the properties of the distribution of human solution times for Traveling Salesperson Problems (TSPs) with increasing numbers of nodes. New experimental data are presented that measure solution times for carefully chosen representative problems with 10, 20, . . . 120 nodes. We compared the solution times predicted by the convex hull…

We tested human performance on the Euclidean Traveling Salesman Problem using problems with 6-50 cities. Results confirmed our earlier findings that: (a) the time of solving a problem is proportional to the number of cities, and (b) the solution error grows very slowly with the number of cities. We formulated a new version of a pyramid model. The…

The purpose of this article is to outline some of the characteristics of children's notions of physical causality and to relate this to how one might expect the typical five-year-old, eight-year-old, and twelve-year-old to approach a problem in science. (Author)

In the present study, and attempt was made to clarify whether right visual field superiority, in terms of shorter latencies to verbal material, transcends the directional scanning tendencies associated with the stimuli. (Author)

Directions are given for student learning activities on illusions, shadows, the spectrum, and colors. (DT)

Reactions to several kinds of deviant behavior were measured by a questionnaire administered to 79 students at the University of Rome (Italy), in which descriptions of acts were varied to show "good", "bad", or "unspecified" actors. (Author/NQ)

Outlines how classification systems or codes, operating in a variety of contexts, regulate the interaction between man and the built environment. Views the ritual forms of the built environment as transmitters of culture. Suggests that this framework might provide a new starting point for investigations into the built environment in use and the…
