Electromyographic indications of laryngeal-area activity during stuttering expectancy

Using surface electrodes, mean microvolt values of laryngeal-area muscle activity were determined for 13 male and 6 female stutterers during 10-sec periods in which single words were silently read and stuttering expectancy was indicated. No significant differences in levels of laryngeal-area muscle activity were found between periods of fluency expectancy and stuttering expectancy preceding both fluent and stuttered speech. The results were interpreted as being nonsupportive of the hypothesis that a breakdown in stutterers' laryngeal-area muscle activity occurs during moments of stuttering expectancy. In addition, the results suggest that the most common rationale for the utilization of laryngeal biofeedback procedures to enhance fluency should be questioned.     

Young adults' perceptions of social sex roles across the life span

Fifty male and 50 female undergraduates rated 10 age-sex targets (Boy, Girl, Adolescent Boy, Adolescent Girl, Young Man, Young Woman, Middle-aged Man, Middle-Aged Woman, Old Man and Old Woman) on 12 semantic differential scales. Compared with female targets, male targets were rated higher on potency and activity scales and lower on evaluative scales. Semantic distance between male and female targets showed a curvilinear relationship with target age. Results suggested that young adult subjects perceive that sex-role differences first increase and then decrease across the life span.An earlier version of this article was presented at the convention of the Western Psychological Association in Los Angeles, California, April 1976.     

Communicative stress and stuttering frequency during normal,whispered, and articulation-without-phonation speech modes

The effect of communicative stress on the frequency of stuttered syllables in 12 adult stutterers reading six different but equivalent passages using normal voicing, whispering, and articulation-without-phonation speech under a stress and a non-stress condition was studied. Although the frequency of stuttering was significantly greater in the normal voicing mode than in the whispering mode and greater in the whispering mode than in the articulation-without-phonation mode, no differences were found between the stress and the nonstress conditions with respect to stuttering.     

An investigation of the perceptual basis of redundancy gain and orthogonal interference for integral dimensions

Redundancy gain and orthogonal interference for height and width were demonstrated in two experiments using a relative coding task with number of intertrial repetitions controlled. Orthogonal interference was shown to be perceptually based rather than simply an intertrial repetitions effect as suggested by Felfoldy (1974). These results from a relative coding task were discussed in terms of the previous multidimensional processing literature. It was concluded that Lockhead’s (1972t model has been applied too generally. An alternative model (a parallel, dimensional analysis stage followed by a stage in which dimensional information is integrated) was suggested.     

Role perceptions: Variations by sex and roles

A Role Perception Scale utilizing a combined projective-objective methodology was developed to assess female and male perceptions of each of three single roles — work, marriage, and parent — and two combined roles — work-marriage and work-parent. Research participants were 134 college students, 88 females and 46 males. Factor analysis of the objective scale, the only part to be scored, resulted in two major orthogonal factors labeled role engagement and competition factors. Sex and role differences for each factor were analyzed using 2×5 split block analysis of variance design with repeated measures. On three out of the five single and combined roles women perceived more engagement than men. In general males perceived roles as more competitive. These sex differences and patterns identified in within-sex analyses across roles are discussed.Parts of this paper were presented at the American Psychological Association Convention, Washington, D.C., September 1976.

The effects of Familial Sinistrality and preferred hand on dichaptic and dichotic tasks

Processing asymmetries for tactile-spatial and auditory-verbal processing were investigated in two studies using the S. F. Witelson (1974, Cortex, 10, 3–17) dichaptic procedure. Experiment 1 used eight right-handed males in a free recall procedure. More shapes were correctly detected by the left hand but only with a right hand response. In Experiment 2, right and left handers with no Familial Sinistrality (FS) were compared with left handers with various types of FS, looking at pre- and postcued order of report and precuing the response hand. No group showed hand asymmetry with pre- or postcuing for either responding hand. Right handers showed no difference with order of report; however, left handers made fewer correct detections for items to be reported second. There were differences between the Parental FS and the Sibling FS groups both on the dichotic listening and the haptic tasks.     

Efficacy of self-instructional training for reducing children''s anxiety in an evaluative situation

Fifty-six fourth-grade children were categorized as either high or low in trait anxiety and then assigned to a self-instruction treatment, minimal-treatment, or no-treatment control condition. At both pretest and posttest, the subjects recited a memorized poem while being videotaped with the expectation that they would be judged on their performance. State anxiety measures, a behavior rating of anxiety, a measure of performance accuracy and the time involved in reciting a poem were obtained at both pretest and posttest. Contrary to expectation, the self-instructional training resulted in subjects' exhibiting greater signs of behavioral anxiety, subjects' hurrying through the task (taking less time to recite the poem) and high trait-anxiety subjects' reporting more state anxiety while anticipating reciting the poem. Correlational analyses indicated that trait anxiety was significantly related to the measures of state anxiety and the behavior rating of anxiety but not to performance accuracy.     

Reasoning in the personal and moral domains: Adolescent and young adult women's decision-making regarding abortion

The present investigation of adolescent and young adult women's reasoning, and decision-making about abortion was conducted to determine whether reasoning about abortion could be described by moral, social-conventional, and personal concepts and to examine relationships between domain of reasoning and action choices. Seventy single women, ranging in age from 13 to 31 and divided between 25 women having abortions, 23 women continuing their pregnancies, and 22 never-pregnant women, were administered a semi-structured clinical interview about abortion and two hypothetical moral judgement dilemmas. A classification task was developed to provide an additional measure of reasoning in different domains. Another 29 single, first-pregnant women provided a comparison of the effects of these procedures on decision-making. Content analysis of the protocols revealed that responses to the abortion interview could be reliably distinguished between concepts of morality and personal issues and their coordination or lack of coordination. Subjects treating abortion as a moral issue were more likely to continue their pregnancies while subjects treating abortion as a personal issue were more likely to obtain an abortion. Differences in reasoning between pregnant and nonpregnant subjects were not observed. Moral responses to the abortion interview were found to be highly related to hypothetical moral judgments.     

Recognition and treatment of incestuous families

Incest is a major mental health problem, in terms of both prevalence and morbidity. Father-daughter incest constitutes the majority of reported cases. The possibility of incest should be considered in a family which includes a violent father, a disabled mother, a child in an adult maternal role, or an acting out adolescent girl. Intervention requires recognition of the criminal and addictive aspects of the father's behavior. Active cooperation between mental health professionals and mandated child protective and law enforcement agencies is necessary for effective treatment. Group therapy and affiliated self-help programs appear to be the treatment modality of choice. Rehabilitation of the family is based upon restoration of the mother-daughter bond as a guarantee of safety for the child.     

Two logit models for external analysis of preferences

A logit vector model and a logit ideal point model are presented for external analysis of paired comparison preference judgments aggregated over a homogeneous group. The logit vector model is hierarchically nested within the logit ideal point model so that statistical tests are available to distinguish between these two models. Generalized least squares estimation procedures are developed to account for heteroscedastic sampling error variances and specification error variances. Two numerical illustrations deal with judgments concerning employee compensation plans and preferences for salt and sugar in the brine of canned green beans.
