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)

Two experiments investigated the relationship between social influence and the number of persons attempting influence. Findings suggest that the manner in which persons are initially organized into groups and aggregates of individuals affects their persuasive impact on observers. (Editor/RK)

Three experiments investigated the influence of positive and negative affect manipulations on children's preferences for small immediate versus large delayed rewards. (Editor)

Students are challenged to investigate a simple electric motor and to build their own model from a battery, wood block, clips, enameled copper wire, bare wire, and sandpaper. Through trial and error, several discoveries are made, including a substitute commutator and use of a radio to detect motor armature contact changes. (DH)

Presents activities and experiments that can be performed with mirrors to illustrate the nature and behavior of light. Includes diagrams, directives and investigative questions. (ML)
