Examines two conceptualizations of guilt and tests the hypothesis that high guilt women would experience more affective guilt following their exposure to sexual stimuli, while both low and high guilt women would experience more anxiety in a nonanonymous condition, e.g., in the presence of an experimenter. (Author/RK)

In three experiments the location of pigeons was monitored during 20-second illuminations of a right or left key presented in various temporal relationships with food delivery. In general, subjects approached a signal positively correlated with food and withdrew from a signal negatively correlated with food. (Editor)

Subjects responded to pairs of test items from learned linear orderings (e.g., Tom is taller than Dick; Dick is taller than Sam, etc.). Results are compared with previous studies of ordered linguistic, perceptual, and numerical information. (Editor/RK)

Criticism of the study relating effects of therapist warmth to desensitization include: the use of surrogate, student subjects; nonstandard desensitization procedures; and no control group. Morris and Suckerman respond that the first two criticisms rely on selective reading of the literature and the third is irrelevant. (NG)

Two experiments were conducted to examine the input-order effect reported by Birnbaum (1975); he demonstrated that free recall of two-digit numbers presented in natural ascending order is superior to free recall of the same numbers presented in random order. (Author/RK)

Attempts to determine whether intentional forgetting instructions influence memory when the opportunity for rehearsal is restricted and whether the intentional forgetting phenomenon could be accounted for by a selective-search hypothesis which states that memory improvement is due to a smaller search set in the cued condition relative to the…

The frequency with which values on any stimulus dimension occur within the positive (and/or negative) category of a concept is a potential cue to which dimensions are relevant. Seven experiments, using a two-stimulus (one positive and one negative) simultaneous presentation paradigm, designed to explore frequency effects systematically, are…

Separation thresholds for groups of 26 dyslexic and normal children attending the first year of secondary school were obtained with pairs of identically-oriented and spatially-overlapping straight lines presented at orientations varying from zero to 90 degrees. (Editor)

The effects of the outcomes "right" and "wrong" upon subsequent correct responding in paired-associate learning have recently been interpreted as a function of subject's memory of previous responses and their outcomes. Tests that interpretation in two experiments of recall procedures. (Editor/RK)

It is much easier to look for an unfamiliar character (such as an upside down A) embedded among familiar ones than to look for a familiar character (A) among unfamiliar ones. Furthermore, the nature of the background seems more important toperformance than the nature of the target. (Editor)

Presents the views of a prominent molecular biologist regarding recombinant DNA research. Contained are arguments for continuing research and a reassurance that the potential hazards from this type of research are overstressed. (CS)

Describes a DNA fingerprinting simulation that uses vegetable food coloring and plastic food containers instead of DNA and expensive gel electrophoresis chambers. Allows students to decipher unknown combinations of dyes in a method similar to that used to decipher samples of DNA in DNA fingerprint techniques. (JRH)

Describes the use of recently constructed stormwater detention ponds to conduct a set of field and laboratory exercises in an undergraduate limnology course. Provides a number of logistical advantages that can benefit those teaching aquatic sciences. (JRH)

Describes an exercise designed to be used in an Advanced Placement (AP) chemistry course to accompany the study of thermodynamics. Uses Differential Scanning Calorimetry in teaching the concepts of thermochemistry and thermodynamics. (JRH)

Presents an experiment that provides students with an opportunity to investigate folk medicine and herbal cures and their accompanying claims. Involves isolating some active compounds from plant materials and demonstrating their antibacterial activity. (JRH)
