Pavlovian extinction,phobias, and the limits of the cognitive paradigm

The slow or total lack of decrease in some autonomic responses during extinction in aversive conditioning and concomitant verbalizations of fear have remained a problem for learning theories and psychophysiology. Removal of the aversive stimulus should result in a rapid decrement in responding, as it does in cognitive and somatic systems. In laboratory analogues of phobia and clinical neurosis, however, such decreases do not occur in some autonomic responses and reported fear. In this article three areas of research are presented in which dissociations occur between cognitive and autonomie responses: 1) relational learning, 2) phobia, and 3) incubation. The data indicate that there are some important distinctions to be made concerning the properties of different psychological and physiological systems. These distinctions pertain to the differences between cognitive and noncognitive systems, between the two branches of the ANS, and between acquisition and extinction processes. These distinctions lead to a number of hypotheses concerning dissociations between response systems and have important implications for the understanding and treatment of neurosis.     

Cooperative education,career exploration,and occupational concepts for community college students

Super's self-concept theory of career development and Jordaan's construct of vocational exploratory behavior were used to investigate the outcomes of a college cooperative education program. The effects of an internship were compared with those of a classroom experience with regard to change in similarity between self- and occupational pictures (incorporation scores). A measure of incorporation was administered to 85 students who worked during one quarter, and 99 students who were enrolled in classes during the same period. Both groups increased in incorporation for prospective occupation (t = .01, p > .10). For the internship group no difference was found between increase in incorporation for first- and second-choice occupation (t = .24, p > .10), while for the classroom group the increase in incorporation for prospective occupation was significantly greater than for second-choice (t = 2.80, p < .01). This result was discussed in light of the implication that the internship stimulated vocational exploratory behavior. Roe's system of occupational classification revealed an unexpected lack of relationship between first- and second-choice occupations. These findings were discussed in relation to the career development of the working-class community college sample.     

A comparison of female and male adolescents' social behaviors and cognitions: A challenge to the assertiveness literature

Sex differences were investigated in the thoughts and behaviors of adolescents in simulated social situations. The pattern of sex differences indicated females to be more appropriately assertive in their overt behaviors than males. Males were more aggressive. In their cognitions females were more likely to deny their impact on others, while males were more likely to deny the impact of others on themselves. Potency training was suggested for females, assertiveness training for males. Cluster analyses of correlations among behaviors and thoughts revealed four clusters for females: external locus of control, internal locus of control, active expressiveness, and social isolation or denial. The three male clusters were a negative impotent one, a positive active cluster, and an aggressive hostile cluster.The research reported is based on a dissertation submitted in partial fulfillment of the requirements for a Ph.D., University of Toronto (OISE). The research was partially funded by OISE Research and Development Grant No. 3478, awarded to the second author.     

Reactivation-induced interference in a short-term retention paradigm

In Experiment 1 it was demonstrated that interference with a rat's retention of a target spatial cue decreases as the interval between prior conflicting cues and the target increases. Experiment 2 showed that interference can occur even when the interstimulus interval is long, if the memory of a conflicting cue is reactivated just prior to exposing an animal to the target cue. A third experiment suggested that these findings could not be easily interpreted in terms of a stimulus satiation effect. The implications of these findings for a trace decay model of short-term retention were discussed.     

ASSESS: Adjustment Scales for Sociometric Evaluation of Secondary-School Students

The Adjustment Scales for Sociometric Evaluation of Secondary-School Students (ASSESS) was designed to assess peer ratings of the behavior of male and female adolescents. Five scales were developed and crossvalidated: Aggression-Disruptiveness, Withdrawal, Anxiety, Social Competence, and Academic Difficulty. Evidence of adequate internal consistency and testretest reliability was presented. Evaluations by male and female classmates were highly correlated. Sex and age differences accounted for only a small proportion of the total variance.This research was supported by Grant MH-21145 from the National Institute of Mental Health and funds from W. T. Grant Foundation. We wish to acknowledge the assistance of Ronda Brooks, Lina Jandorf, and Jean Sullivan in conducting the data collection, as well as the many school districts that have cooperated.     

The lady spaceman: Children's perceptions of sex-stereotyped occupations

In a study of perceptions of sex-sterotyping in occupations, children from first, fourth, and sixth grades in single-sex schools and a coeducational school were asked to name male and female occupants of traditionally male and traditionally female roles. Use of linguistic markers (e.g., lady doctor) or stereotypically inappropriate responses (e.g., naming a female doctor nurse, while correctly naming the male occupant of this role doctor) was associated with labeling female occupants of traditionally male roles and male occupants of traditionally female roles. The results from this study indicate that language subtly reflects children's perceptions of sex roles.This study was supported by a grant from the Melbourne State College Standing Committee on Research and Development.     

Task-hemispheric integrity in dual task performance

A condition of task hemispheric integrity is predicted to result in a dual task situation when the central processing and response components of each task are associated exclusively with a given cerebral hemisphere. The prediction that this condition will generate more efficient time-sharing is tested in a series of four experiments. In experiment 1 the prediction is confirmed when a spatial (tracking) and verbal (letter memory search) task are time-shared, and the hand assignment to task responses is manipulated. In experiment 2 a spatial variant of the memory search is used instead of the verbal letter search, and hand assignment effects are not obtained, since when two spatial tasks are time-shared an integrity assignment is impossible. Experiment 3 validates the hemispheric lateralization of the two single task variants of the memory search task, while experiment 4 establishes the separate “spatial’ and “verbal” resource demands of the two variants by observing their differential interference with concurrent spatial and verbal tasks.     

The costs of selecting power bases or messages associated with the opposite sex

A study was conducted to examine the interpersonal costs of using power bases associated with the opposite sex. The study also tested two hypotheses regarding influence differences associated with two statistical interactions: (1) the sex of the source by the sex-type of the message, and (2) the sex of the subject by the sex-type of the message. Subjects (N=387) viewed a videotype containing one of six speakers (three males, three females) delivering one of two speeches (about gun control or child care centers) and using one of two power bases (helplessness or expertise). The results indicated that speakers using power bases associated with the opposite sex were liked less and regarded as less competent and qualified than their counterparts. The results also indicated that female speakers aroused more belief in the child care message and male speakers aroused more belief in the gun control message than did the other speaker-message combinations. No significant effects were associated with the interaction between subjects' sex and message. Among other findings, female subjects generally rated the messages and the speakers more positively than did male subjects.
