The effect of force requirements on response effort was examined using outbred (CD-1) mice trained to press a disk with their snout. Lateral peak forces greater than 2 g were defined as threshold responses (i.e., all measured responses). Different force requirements were used to define criterion responses (a subclass of threshold responses) that…

TWO SERIES OF STUDIES WHOSE SUBJECTS WERE EITHER HOODED AND ALBINO RATS OR YOUNG CHILDREN INVESTIGATED THE INFLUENCE OF EARLY EXPERIENCES ON LATER BEHAVIOR. IN THE FIRST, BOTH SUBSPECIES OF RATS WERE EXPOSED TO EITHER ENRICHED OR RESTRICTED ENVIRONMENTS TO ASSESS THEIR PROBLEM-SOLVING ABILITIES UNDER VARIOUS LEARNING CONDITIONS. THE RESULTS…

Four research papers discuss the influence of social cues on children's behavior. Specifically, the focus of this program of research was to systematically investigate the impact of two classes of social cues: (1) implicit or explicit instructional cues inherent in social interactions, and (2) inferred or actual evaluative cues present in…

A description is provided of a computer-based simulation of an instructional system which adapts the learning environment to the individual's unique attributes for processing information and for being motivated. The main purposes of the simulation are: 1) to introduce, as attributes for individualizing instruction, information processing variables…

A study was done to investigate the relationship between a selected set of personality dimensions and the propensities of supervisors to use varying levels of both positive and negative reinforcements. Data were collected during exercises involving 129 male undergraduate business students carried out in a behavioral laboratory wherein a…
