Sexual arousal,situational restrictiveness,and aggressive behavior

Eighty male college freshmen participated in an experiment designed to investigate the hypotheses that enhanced arousal will facilitate subsequent aggressive behavior and that an increase in aggressive behavior will be more likely to occur in a setting of situational permissiveness rather than situational restrictiveness. Subjects were either angered or not angered by a same-sex confederate, then told to imagine either a sexually arousing or a nonarousing situation during relaxation, and finally provided with an opportunity to aggress against this person by means of electric shocks. For half of the subjects, a setting of permissiveness was created, while for the other half the setting was one of situational restrictiveness. The results indicated that, even in a permissive setting, sexual arousal may inhibit aggressive behavior mediated by self-consciousness or anxiety. For nonaroused men, however, situational permissiveness tended to facilitate subsequent aggression. The investigation was considered a replication and an extension of the Baron (1974) study on the aggression-inhibiting influence of heightened sexual arousal.     

Recall of semantic clusters in primary memory

An experiment is reported which investigated the use of semantic relatedness as a retrieval cue in the primary memory component in a free recall task. Six-word semantically related clusters were placed in the middle and end positions of free recall lists. Retention was measured immediately after the list presentation and after a filled retention interval of 15 sec. Pure primary memory functions were calculated. The results indicated that semantic cues are useful in retrieval from secondary memory but played no part in recall from primary memory.     

Visual resolution in the periphery

Visual acuity thresholds were determined for two Os with a 3-deg square grating target presented for 0.2 sec within a steadily illuminated surround field matched in luminance to the test field. Measurements were made in the fovea, and at 10, 20, and 30 deg along the horizontal meridian of the temporal retina, at luminances between ?3.5 and 3.0 log mL. The foveal acuity-luminance functions showed a large increase in acuity up to 1 or 2 log mL, but at peripheral locations very little increase occurred above 0 log mL. The maximum acuity reached at photopic luminances dropped sharply with increasing eccentricity. Visual acuities were two to four times higher than those previously reported for the periphery; methodological and target differences are presented to account for this result.     

The effects of a variety of instructions on human fixed-interval performance

College students were instructed to press a button for points under a single reinforcement schedule or under a variety of reinforcement schedules. Instructions for a single schedule were either specific or minimal. Instructions on a variety of schedules involved specific instructions on eight different schedules of reinforcement. Subsequent to the varied training, responding under a fixed-interval schedule occurred at a low rate. Both the minimal and specific instruction training led to fixed-interval responding that was similar to the responding exhibited during training. These findings suggest that under certain conditions instructed behavior is sensitive to changes in contingencies.     

Some deleterious consequences of the act of recollection

Two experiments investigated the impact of responding to recognition test items that do not include a correct alternative. In Experiment 1, subjects who were given exclusively incorrect response alternatives were less likely than control subjects to favor the correct alternatives on a second recognition test. Analysis of subjects’ responses indicated that commitments, rather than distractor familiarity, was the main source of this effect. In Experiment 2, an impairing effect of committing to an incorrect alternative was observed even when the initial distractors were excluded from the final test. Thus, this decreased performance cannot simply be attributed to a bias toward remaining consistent. One interpretation of these results is that committing to a distractor causes subjects to remember a false detail that can interfere with their later ability to access the original information. Other potential theoretical and applied implications of these results are explored.     

Brief crisis group psychotherapy versus the initial sessions of long-term group psychotherapy: An exploratory comparison

An attempt was made to specify the therapist behaviors characteristic of the brief crisis group (BCG) approach, to assess how patients experience BCG on dimensions of session impact and group climat, and to describe the changes possible from BCG on measures of outcome by contrasting this modality with the initial sessions of traditional long-term therapy groups in a preexperimental design. Data obtained from four eight-session BCGs and three beginning long-term groups (LTG) were used for analyses. Patients were administered the Session Evaluation (SEQ) and Group Climate (GCQ) Questionnaires at the end of each group session. Two judges sat in on each session and coded the types of therapist interventions using the Therapist Behavior Categories (TBC) system. Aspects of self-esteem and symptomatology were assessed as indices of change over the 8-week period in a pre-post fashion. Therapists in BCG evidenced a distinct pattern of interventions during midpoint group sessions (sessions 3–6), placing a greater emphasis on challenging patient perceptions and providing information than their LTG counterparts. The therapists' use of self as an issue in BCG increased as termination approached and apparently served a more limited function than in LTG. Patients in BCG reported a more rapid development of a working group and experienced greater session benefit. Patients in BCG also reported lower levels of conflict and avoidance and a greater decrease in these resistance behaviors. As expected, BCG patients reported substantially greater improvement on most outcome dimensions at the end of the 8-week period. Results are considered as clarifying the approach to and impact of BCG psychotherapy.An earlier version of this paper was presented at the 15th Annual Meeting of the Society for Psychotherapy Research, Lake Louise, Alberta, June 19–23, 1984.     

Dominance bonding through the good old boys sociability group

Informed and illustrated by observational and interview data on two sample groups, a model of one particular form of male social groups was elaborated. Because of the characteristics of its members and its operating principle, the ideal type was labeled the Good Old Boys Sociability (GOBS) group. Members of GOBS groups share successful class and gender histories, and plan and engage in events that reflect dimensions of masculine play learned in boyhood. The GOBS group was found to perpetuate masculine identity and male privilege through dominance bonding, i.e., a process of collective alliance in which members affirm and reaffirm their superiority.     

The effects of linguistic experience on cerebral lateralization for speech production in normal hearing and deaf adolescents

The cerebral lateralization patterns for speech production in 57 normal hearing and deaf adolescents were studied using the dual-task paradigm. Normal hearing subjects showed left hemispheric dominance for speech production, whereas both the congenitally deaf and those with early acquired deafness showed atypical cerebral representation for speech production. Deaf subjects whose hearing loss occurred after 2 years of age displayed a pattern of mixed cerebral dominance related to complexity of speech production or task difficulty. These results are interpreted as evidence for a relationship between linguistic/cognitive stage of development and the ontogenesis of cerebral lateralization. A parallel lateralization hypothesis of left cerebral dominance for speech production is offered.     

An observational study of emotionally disturbed and learning-disabled children in school settings

It has been alleged that populations of learning-disabled (LD) and emotionally disturbed (ED) children are essentially indistinguishable on important intervention-related symptoms. To examine this claim, a direct observation study of social interactions during class, lunch, and recess settings in two public schools was conducted. Teacher ratings of school behavior were also collected. The results indicated that the ED boys exhibited significantly more nonphysical aggression and noncompliance than the LD boys across settings, and that the LD boys had significantly higher rates of physical and non-physical aggression and immature behavior than the LD girls. The correlations between the observations and teachers' ratings were modest but consistent with previous studies. The results are discussed with regard to their assessment and treatment implications.This study was supported, in part, by a grant from the National Institute of Mental Health (MH30058).
