Sticks, string and observation start children off on the bare bones of human biology. (Editor)

The experiments reported here are aimed at exploring in more detail the possibility that context can improve perception itself. In particular, they are concerned with clarifying the conditions under which context might aid perception and with localizing the stage of processing at which context would have its effects.

These experiments were designed to assess the linguistic performance of the right hemisphere by using reaction time (RT) to measure the flow of information in the normal brain. RT to lateralized stimuli has proved to be a powerful tool for detecting functional differences between the hemispheres on a variety of cognitive tasks. (Author/RK)

Two free-recall experiments were performed in which the subjects were required to rehearse items an equal number of times, but the number of items presented at a given time was varied. The main hypothesis was that increasing the number of items presented at once would increase processing demands and decrease performance. (Editor)

The generalizability of the Fishbein model for behavior prediction was extended to a new field of behavior, alcohol drinking by adolescents. This research investigated the predictive importance of the model's two components, attitudes and normative beliefs. (Editor/RK)

An introductory biophysics course for science students who have previously taken two quarters of noncalculus physics is described. Material covered emphasizes the physical principles of sound, light, electricity, energy, and information. (Author/CP)

The authors give directions for comparing the rates of zero and first order chemical reactions to the rate of flowing water in simple physical systems. They also show how to compare chemical equilibrium to the level of water in a u-shaped tube. (AJ)

Describes a method of calculating the power applied to an electric lamp by using a calorimeter to measure the energy radiated by the lamp. (SL)

These experiments are addressed specifically to the question of whether transituational transfer of immunizing and therapeutic effects will occur when these procedures involve responses and settings which are very different from those used in final testing. (Author/RK)

This research studied the relation between mastery of the words "and" and "or" and performance on the conjunctive and disjunctive tasks. A definition test was used to measure level of mastery of the linguistic terms and a traditional logical test to measure logical task performance. Results are related with ability to solve logical tasks.…

A broader approach to research in human development is proposed that focuses on the progressive accommodation, throughout the life span, between the growing human organism and the changing environments in which it actually lives and grows. The approach emphasizes the use of rigorously designed experiments, both naturalistic and contrived,…

Subjects learned lists of words under conditions of high, medium, or low expectations concerning test-phase cheating and were then tested for recall with cheating precluded. Test performance of subjects expecting to be able to cheat was unexpectedly better, rather than worse, than subjects with low expectations, even when cheating was precluded.…

It has been demonstrated that instructions to learn have no effect on immediate recall in the incidental learning paradigm used by Jenkins (1974). This research further investigated this finding by factorially manipulating recall instructions (incidental vs. intentional learning), presentation rate of materials, retention interval, and type of…

Studies the processing of pictures and words as symbols. Shows that the superiority of pictures results from the fact that pictures are interpreted more quickly than words, but that after the interpretation is made, processing is the same. Also gives evidence that pictures and words are both processed in terms of linguistic codes rather than…

Three experiments were conducted to evaluate the P300 component of the human evoked response as an index of bisensory information processing. Data shows that the P300 promises to be a valuable tool for assessing brain processes during complex decision making. (Editor/RK)
