The social phobia and anxiety inventory: Construct validity

The Social Phobia and Anxiety Inventory (SPAI) is a new instrument composed of social phobia and agoraphobia subscales. The latter scale is used to detect social anxiety that may result from agoraphobia. The SPAI's construct validity was assessed through several procedures. First, confirmatory factor analyses were conducted to validate the existence of the two subscales. Second, exploratory factor analyses examined the underlying structure of the social phobia subscale. Third, a Q factor procedure determined if different anxiety diagnostic groups could be differentiated by their SPAI response pattern. The results confirmed the utility of the two SPAI subscales and identified a number of dimensions contained within the social phobia subscale which differed depending upon the specific subject sample. In addition, the complaints of social phobies appeared more homogeneous than those of an agoraphobic comparison group. The results are discussed in terms of construct validity and the sensitivity of the SPAI to various dimensions of social phobia fears.This study was supported in part by NIMH Grants 41852, 30915, 18269, and 16884.     

Differential visual field-interhemispheric transfer: can it explain sex and handedness differences in lateralization?

104 men and women were tested for visual field-hemispheric transfer of spatial information on a dot-localization task. Right-handed subjects showed significant improvement when stimuli were presented to the left visual field of the right hemisphere (LVF-RH) after practice on the same task presented to the right visual field of the left hemisphere (RVF-LH) first. No improvement was found when the task was presented in the reverse order (LVF-RH first followed by RVF-LH). It was concluded that, for right-handers, transfer of spatial information to the right hemisphere is facilitated while transfer to the left hemisphere is inhibited. Left-handed subjects demonstrated no significant improvement in either condition, suggesting inhibition or lack of transfer of spatial information in either direction. No sex differences were found in either right-handed or left-handed subjects. The findings suggest that there may be different mechanisms underlying the similarities in functional lateralization of women and left-handers.     

Mental representation from the bottom up

Commonsense psychology and cognitive science both regularly assume the existence of representational states. I propose a naturalistic theory of representation sufficient to meet the pretheoretical constraints of a folk theory of representation, constraints including the capacities for accuracy and inaccuracy, selectivity of proper objects of representation, perspective, articulation, and efficacy or content-determined functionality. The proposed model states that a representing device is a device which changes state when information is received over multiple information channels originating at a single source. The changed state of a representing device is a representation. The unitary information source which would give rise to the information impinging on the representing device, and hence, give rise to the representation, is the content of the representation. The model meets the pretheoretic constraints, and also conforms to available neurobiological data for two invertebrate species.     

Vocal frequency and person perception: Effects of perceptual salience and nonverbal sensitivity

Previous research has demonstrated that changes in vocal frequency (pitch) influence judgments made about a speaker, although there is some question as to the relative importance of frequency to message content in person perception. Moreover, these studies have failed to examine the possible joint effect of frequency and individual differences in nonverbal sensitivity on person perception. The purpose of the present investigation was to examine the independent and joint effects of vocal frequency, perceptual salience, and nonverbal sensitivity (assessed by the Profile of Nonverbal Sensitivity) on person perception. Participants were assigned to one of nine experimental conditions and were asked to rate two male and two female speakers on seven unipolar adjective scales. The nine conditions were produced by factorially combining three levels each of salience (content, voice, control) and vocal frequency (decreased, increased, unmanipulated). The results of hierarchical multiple regression analyses indicated that variations in frequency did influence evaluative judgments of the speakers (competent, honest, persuasive), but that the magnitude of the influence varied as a function of the participants' levels of nonverbal sensitivity. The analyses, however, yielded no significant effects for participants' affective judgments, nor any significant effects involving perceptual salience.     

Incidental learning,distraction, and sustained attention in hyperactive and control subjects

Thirty-two children designated as hyperactive (ADD) were compared with an equal number of control subjects who were matched for age, sex, and verbal IQ. The subjects were tested on (1) a component selection task, measuring serial memory and incidental learning and (2) a cancellation task, assessing attentional variables and distractibility. No straightforward group differences were found on the component selection task, whereas hyperactive subjects made more omission and commission errors than controls on the cancellation task. It was concluded that a deficit in sustained attention and impulsivity best described the group differences. Age was also found to influence performance on a number of variables, including incidental learning on the component selection task and response rate and omission errors on the cancellation task. Because subjects in the hyperactive group were rated as extreme on a number of subscales not necessarily related to hyperactivity, the data were reexamined by multiple regression analyses. Subscales considered to be related both to hyperactivity and to conduct disorder were associated with different performance variables, indicating that each of these subscales provided some unique information.This study was supported by a grant from the Medical Research Council of New Zeland to the first author.

Effects of body size and body mass on the swimming performance of preschool children

This research examined the relationship between body size and mass and the performance of 3- to 6-year-old children (n=117) on two categories of swimming tasks: Locomotion: Front and Locomotion: Back. The major hypothesis was that body size and mass measurements would be good predictors of children's swimming performance. The function of age/gender also was examined. Stepwise multiple regression was used to select the best predictors of swimming performance after controlling for amount of aquatic training and child's apprehensiveness about water. Body weight was the best predictor of children's swimming performance on each category of tasks (p<0.01). It accounted for at least 16% of performance variation when entered alone, and it accounted for 5% given age. Age was of little importance after body size and mass were taken into account. The major conclusion was that future research should incorporate more complex research designs to account for the network of influencing factors.     

Sex role stereotyping in the sunday comics: Ten years later

The present research replicates Brabant's (Sex role stereotyping in the Sunday comics. Sex Roles, 1976, 2(4), 331–337) analysis of sex role stereotyping in family-oriented Sunday comics. Cartoons were collected for the same six-month period and compared to the 1974 data. Females continue to appear less frequently and to remain in the home more often than males. They also continue to be protrayed in stereotypical roles.     

THE PASSIONATE MIND: BRAIN, DREAMS, MEMORY, AND SOCIAL CATEGORIES

Abstract. The intellectualist position held by structuralists does not explain the extremes of emotional reaction to the disruption of social categories. An approach from neuroscience based on the functions of the limbic system in the creation of long-term memory through the role of the hippocampus and REM sleep is proposed to account for the emotive loading of cognitive categories.     

An address-mode modification method for self-report questionnaires

A technique comparing first-person singular and first-person plural address modes (based on the Tennessee Self-concept Scale and modifications) was applied. Self-report and sociometric-like techniques were blended into a single method, providing a compound profile of the individual's interaction with his small, cohesive reference group. One hundred and sixteen males aged 18–22 yr participated in this study. The results vary significantly in accordance with the characteristics of the subgroup, and follow trends that may be seen as confirming the rules governing the interpretation of the profile. A set of rules is evolved (in the Discussion) by which the profile can be interpreted. The results distinguish significantly between people with marked leadership and instructional skills, and provide significant correlations with sociometric data concerning leadership propensities. The present technique suggests possible further elaborations for clinical diagnostic purposes and for assessment in personal and social psychological settings.
