The research reported here was directed at evaluating whether or not the effectiveness of a Pavlovian unconditioned stimulus (US) in promoting associative learning is reduced if the US is shortly preceded by another occurrence of the same US. (Author)

Discusses a teaching program for introductory chemistry laboratories that allows for differences in student background and ability. The flexible program involves self-pacing and a classification of experiments; this permits slower students to proceed through remedial loops while advanced students proceed to more difficult experiments. (MLH)

Describes an interpretative experiment involving the application of symmetry and temperature-dependent proton and fluorine nmr spectroscopy to the solution of structural and kinetic problems in coordination chemistry. (MLH)

Investigates the effects of medium, task, and instruction on the child's representation of the human figure, the origins and course of development of the child's representational effort, and the effects of socioeconomic status (SES), intelligence, age, sex, and mental retardation on the representation of the human figure. (Author/RK)

Recent data indicate that the form of the conditioned response (CR) may often be substantially influenced by the characteristics of the conditioned stimulus (CS) as well as by those of the unconditioned stimulus (US). Here five experiments examine the influence of CS characteristics on the form of the Pavlovian CR anticipatory to a food US in…

Sought to elucidate the nature of odor memory by applying paradigms from verbal learning and semantic memory and to investigate two processes affecting paired-associate performance. (Author/RK)

Sequences of seven tones were presented, and recognition memory for individual tones of each sequence was tested under varying degrees of context. (Editor)

Investigates the effects of verbal labels on the short-term retention of a simple motor skill. (Author/RK)

Examines Lerner's work on the justice motive. Central to this view of justice is the notion that people are motivated to eliminate the innocent suffering of others and will do so providing the act of help does not jeopardize the individual's ability to maintain deserved outcomes. (Author/RK)

A field study and a laboratory experiment were conducted to test the hypothesis that the method by which an attitude was formed is a crucial variable affecting attitude-behavior consistency. (Editor)

Discusses methods for observing oscillations in a chemical reaction about a steady state en route to equilibrium. (MLH)

Discusses advantages of radial diffusion assay in determining presence of enzyme and/or rough approximation of amount of enzyme activities. Procedures are included for the preparation of starch-agar plates, and the application and determination of enzyme. Techniques using plant materials (homogenates, tissues, ungerminated embryos, and seedlings)…

Demonstrates that categorization of speech sounds can be influenced by the phonetic structure of connected speech. (Editor/RK)

The central question in these experiments concerns the effect of unattended printed words upon a picture-naming task to determine whether print can be read even when it is not being attended to. (Author/RK)

Discusses two propositions about the preliminary stages of acoustic analysis and encoding in the absence of focal attention. (Editor/RK)
