Facial asymmetry in posed and spontaneous expressions of emotion

Patterns of facial asymmetry (i.e., extent of movement) as a function of elicitation condition, emotional valence, and sex of subjects are examined. Thirty-seven right-handed adult males and females were videotaped making positive and negative expressions of emotion under posed (verbal, visual) and spontaneous conditions. There were no differences in facial asymmetry as a function of condition. Overall, expressions were significantly left-sided, a finding implicating the right hemisphere. When sex and valence were considered, negative expressions were left-sided for all subjects, while positive expressions were left-sided for males only. Further, positive expressions were significantly less lateralized than negative ones for females. Measures of hemiface mobility and ocular dominance did not mediate these patterns of facial lateralization.     

Profiles of symbol-reading skills in organic patients

One (unitary) school of thought views all symbolic competences as closely related, while a rival (pluralistic) approach underscores the relative differences among modes of symbolic processing. To secure information on the plausibility of these competing hypotheses, matched groups of left- and right-hemisphere patients were given a visual symbol-recognition test. Subjects were required to choose the correctly depicted symbol among a set of four. The results challenge a strong version of the “unitary” hypothesis. What emerges instead is a view of symbol systems as a continuum: relatively linguistic symbol systems prove challenging for left-hemisphere patients, relatively nonlinguistic systems pose comparable difficulties for right-hemisphere patients. Contrary to hypothesis, the processing of numerical symbols poses special difficulty for right-hemisphere patients. Performance on trademarks—items which can be processed by linguistic or nonlinguistic strategies—suggests that organic patients with contrasting pathologies may adopt different processing strategies when confronting identical physical stimuli.     

An experimental analysis of exposure to “explicit” heterosexual stimuli as an effective variable in changing arousal patterns of homosexuals

The effect of exposure to explicit heterosexual stimuli on heterosexual arousal was experimentally analyzed in four homosexuals in a series of single case experimental designs. Each subject was sequentially exposed to films of female or male sexual content under positive therapeutic instructions. Penile response to female slides in separate measurement sessions increased during exposure to the female film, decreased during exposure to the male film, and increased once again when the female film was reinstated. The increase in penile response to female stimuli was paralleled in many instances by changes in masturbatory fantasy, reports of arousal and heterosexual behavior outside the laboratory. Increasing heterosexual arousal had little effect on homosexual responsivity. Results are discussed in terms of exposure facilitating extinction of avoidance responses toward females and providing new sexual fantasy content.     

Comparison of vocational school graduates and dropouts

Graduates and dropouts from six vocational training programs were compared on data taken from school records and from their responses to a questionnaire. Results revealed that age, level of education, high school completion, marital status, physical or health disabilities, and GATB scores were not significant factors in distinguishing between graduates and dropouts in vocational training programs. Two significant factors were: (1) whether the vocational school offered the student's first choice of a vocational program, and (2) whether a student transferred from a college academic program to a vocational program or directly entered a vocational program without prior college academic work.     

Listener preferences for stuttered and syllable-timed speech production

The purpose of this study was to determine how “naive” listeners react to syllable-timed speech production. Three stutterers were videotape recorded while speaking in their usual manner and pacing their speech at 100 words per minute (wpm) and 70 wpm. Twenty-three listeners rated the speech samples as to which they preferred to hear. The results indicated generally that listeners preferred paced speech to stuttering.     

Invasions of personal space and helping: Mediating effects of invader's apparent need

A field experiment was conducted to examine the influence of invasions of personal space and invader's apparent need upon subsequent helping. On the basis of previous research, it was predicted that helping would be inhibited by invasions of personal space when the invader's apparent need for assistance was low, but would actually be facilitated by such intrusions when his/her apparent need for assistance was high. Results offered support for both of these predictions. Additional findings suggested that these differential effects of invasions of personal space may have stemmed, at least in part, from the induction of contrasting affective reactions among subjects under conditions of low and high apparent need.     

Vocal control therapy for stutterers: A trial program

A problem-solving approach to the treatment of stuttering, called vocal control therapy, has been shaped over a 4-year period. The program includes behavioral desensitization techniques as well as retraining vocal, respiratory, and other speech functions for fluency. Data from pre- and posttherapy video tapes of 12 out of 34 cases are given. Theoretical and clinical implications are discussed.
