The behavioural treatment of sexual inadequacy: A comparative study

Thirty-six couples complaining of sexual difficulties were treated with one of three methods: (1) systematic desensitisation plus counselling. (2) directed practice—based on that of Masters and Johnson—plus counselling. (3) directed practice with minimal contact. Both members of each couple were seen together, but half in each treatment group were treated by a single therapist and half by a therapist pair. Differences in outcome among the groups were not highly significant, but consistent trends were found which suggested that the combination of directed practice and counselling was associated with most change, particularly when two therapists were involved.     

The discrimination of brief temporal intervals

The discrimination of brief durations (0.25 to 3.75 sec) defined by the presentation of a visual stimulus was examined. The results indicate that the Weber fraction is invariant over this range of temporal intervals, and that the value of the fraction is about 0.05. The relation of these results to the literature on temporal discriminability was discussed.     

Delayed one-trial extinction of the McCollough effect

Initial tests of the McCollough effect were made on separate groups at delays of 4, 24 or 96 h after induction, with little apparent decrement. Subsequent tests were made at 4, 24 and 96 h after each initial test delay, again using separate subject groups in order to avoid test-induced extinction. All tests consisted of magentagreen nulling of the aftereffect. A single test session, whenever administered, seems to initiate a decay or extinction process lasting several days, resembling the time course shown by repeated testing. These results are difficult to reconcile with a perceptual conditioning model of the McCollough effect.     

The perceptual similarity of mirror-image acoustic patterns in speech

Prevocalic and postvocalic (unreleased) occurrences of a stop consonant differ in acoustic shape, but are not unrelated. In particular, the formant transitions taking place at release of a stop consonant approximately mirror in time the formant transitions occurring during closure, assuming that the vowel is the ~same. Several experiments have been performed using brief two-component tone burst approximations to the second and third formant transitions’ that occur in prevocalic and postvocalic allophones of/b, d, g/in order to determine whether such mirror-image acoustic patterns are perceptually related. Listener judgments of similarity within triads of these stimuli indicate that mirror-image patterrts representing the same place of articulation are less similar to each other than to patterns representing different places of articulation. Implications for the child who is acquiring language of the fact that mirror-image patterns in speech do not have inherent perceptual similarity are discussed.     

Women as authority figures: The use and nonuse of authority

This paper reports the results of two experiments designed to investigate the effect of sex-role stereotypes on evaluations of authority figures. Female and male subjects read short accounts of various situations in which an authority figure confronted a subordinate who had transgressed in some way and then evaluated the authority figure on a variety of dimensions. Sex of the authority figure and of the subordinate were varied factorially. In Experiment 1, where the authority figure took a hard line with the transgressing subordinate, it was found that a female authority figure being firm with a male subordinate was evaluated most negatively. In Experiment 2, where the authority figure was lenient with the subordinate, it was found that a female authority figure being lenient with a female subordinate was evaluated most negatively. Implications of the results are discussed.     

The perception of dichotic chords by hemispherectomized subjects

Hemispherectomized subjects display a strong ear dominance in their perception of dichotically presented two-tone chords. The frequency of the tone presented to the ear contralateral to the remaining hemisphere dominated the pitch mixture of the chord. The described effect does not vary with the age at which the hemispherectomy was performed. These results are consistent with the hypothesis, developed to account for findings in normal subjects, that the pitch mixture of a dichotic chord is determined by a subcortical pitch processor. The effects observed in hemispherectomized subjects may result from an interruption of an efferent pathway from the cortex to the subcortical pitch processor or from an asymmetrical degeneration of the processor which may be located in the thalamus (medial geniculate).     

The role of converging lines on the perception of vertical lines: A Ponzo illusion variant

An experiment was performed to examine the effect of the angle of converging contours on the subjective midpoints of vertical lines. According to the inappropriate size-constancy scaling theory of Gregory (1963) increasing the angle of converging contours should increase the apparent depth of the figure and therefore exert a measureable influence on the subjective midpoints of vertical lines enclosed by the contours. However, this manipulation was not found to affect the subjective midpoints of test lines indicating that an explanation of the Ponzo illusion based on the operation of inappropriate size-constancy scaling must be restricted to certain test configurations.
