Validity of the Sex-Role Egalitarianism Scale: Two replication studies

To enhance the construct validity of the Sex-Role Egalitarianism Scale (SRES), two replications of earlier validity studies were undertaken. Samples were from several college campuses and primarily Caucasian. In Study 1, multiple regression analyses confirmed a hypothesized curvilinear relationship between scores on the SRES and scores on the MacDonald Sex Role Survey, a measure of gender role ideology regarding women. In Study 2, the expectation that SRES would share a relatively small amount of total variance with both the Femininity/Expressiveness and Masculinity/Instrumentality trait subscales of the Personal Attributes Questionnaire was supported. Both sets of results are consistent with earlier validity research using different measures.Lynda King would like to express her appreciation to the Central Michigan University Research Professorship Award program for its support of the studies reported here. The authors would also like to thank the anonymous reviewers for their thoughtful guidance and suggestions.

Computer use in psychology instruction: A survey of individual and institutional characteristics

This paper reports the results of a national survey of psychology faculty regarding their instructional use of computers. The survey was designed to answer three general questions: (1) In what ways and to what extent are psychologists using computers in their instruction? (2) What individual characteristics differentiate among levels of users? (3) What institutional characteristics appear to promote or inhibit the instructional use of computers? The results reveal that, although there appears to be extensive use of computers to support instruction, there are both institutional and individual characteristics that differentiate among levels and types of use. Several factors are identified that could lead to increased instructional use of computers, but their impact will largely be determined by the characteristics of the individual and the institution.     

Self-control in hyperactive boys in anger-inducing situations: Effects of cognitive-behavioral training and of methylphenidate

The effects of cognitive-behavioral intervention and methylphenidate on anger control in hyperactive boys were investigated in two studies. The anger-inducing stimuli in both studies involved verbal provocation from peers. Study 1 assessed a brief intervention using self-control strategies, while Study 2 employed a longer training period and a control intervention that focused on enhancement of empathy. Both studies included methylphenidate versus placebo comparisons. Methylphenidate reduced the intensity of the hyperactive boys' behavior but did not significantly increase either global or specific measures of self-control. Cognitive-behavioral treatment, when compared to control training, was more successful in enhancing both general self-control and the use of specific coping strategies. There was no advantage for the combination of methylphenidate plus cognitive-behavioral intervention. Implications for intervention to ameliorate the social and interpersonal difficulties of hyperactive children are discussed.Major support for this study was provided by NIDA grant 01070. This research was also facilitated by a grant from the Spencer Foundation. The many training staff and raters, too numerous to mention individually here, are deserving of our special thanks. We also appreciate the cooperation of Marion Jacobs and the staff of the UCLA Psychology Clinic, where the first study was held, and of Howard Adelman and the staff of Fernald School, where the second study was housed; the clinical and administrative skills of Stephen Alkus, who organized the intervention program for the first study; the talents and diligence of David Neswald, who coordinated much of the videotape scoring; and the ever-present contributions of Doris Finck, who also edited and dubbed the video segments. Medication and placebos were supplied by CIBA-Geigy.     

A SOCIAL ECOLOGY OF HYPERACTIVE BOYS: MEDICATION EFFECTS IN STRUCTURED CLASSROOM ENVIRONMENTS

Hyperactive boys on methlyphenidate (Ritalin), hyperactive boys on placebo, and comparison boys were observed in quasi-naturalistic classroom settings. Ambient stimulation (quiet versus noisy conditions) and source of regulation (self-paced versus other-paced activities) were varied in a 2 × 2 design. Compared to their peers, hyperactive boys on placebo showed lower rates of task attention and higher rates of gross motor movement, regular and negative verbalization, noise-making, physical contact, social initiation, disruption, and acts that were perceived as energetic, inappropriate, or unexpected. Self-paced activities resulted in increased rates of verbalization, social initiation, and high-energy episodes. High ambient noise levels reduced task attention and increased the rates of many other behaviors including verbalization, physical contact, gross motor movement, and high-energy acts. Medication-by-situation interactions emerged for both classroom dimensions, with hyperactive boys on placebo being readily distinguishable from their peers under some classroom conditions and indistinguishable under other conditions. Moderate relationships were found between teacher ratings and many individual behavior categories. Discussion focused on (a) the merits and limitations of a social ecological research perspective, and (b) the implications of these findings for the design of intervention strategies.     

Interference in memory for pictorial information

Subjects studied either faces composed from visual features or verbal facts composed from concepts. Recognition times were increased for both faces and facts when they were composed of elements that occurred in multiple study items. In Experiment 1 the interfering effect of other study items was much larger for verbal facts than for faces. This difference was largely eliminated in Experiment 2 where care was taken to control the features by which the faces were encoded. Experiment 2 also showed that verbal information could interfere with pictorial information and vice versa. However, this cross-modality interference was much weaker than within-modality interference. The data are consistent with the ACT theory in which pictorial material and verbal material are stored together in an abstract propositional network. The subnode model (Anderson, Language, memory, and thought, Hillsdale, N. J.: Lawrence Erlbaum, 1976) can account for the greater within- than cross-modality interference.     

Intrusiveness and Persuasive Impact of Three Communication Media1

Two field experiments compared the persuasive impact of communications delivered face-to-face, by telephone, or by letter. In both studies, letters did not differ from faccto-face contacts but telephone calls were less effective. In the second experiment, personalness interacted with communication medium such that addressing subjects by name reduced the impact of face-to-face encounters, increased that of letters, and had no effect on phone calls. A third sample of subjects rated the appropriateness of name usage by salespeople, indicating a salesperson should give his own name but was inappropriately personal when calling the subject by name. The findings support the notion that varying media and name usage varies the psychological distance between communicator and recipient. At appropriate psychological distances, communicators and communications have optimum effectiveness; at too great or too little distance, they lose impact. Thus, not only is selection of proper medium important to communicators but how the medium is used can affect impact.     

Married women's work status: The influence of parents and husbands

The working or nonworking status of married women free of the financial need to work was studied in relation to the balance between their instrumental and expressive needs and in relation to their own and their husbands' attitudes towards women's roles. Also studied were women's needs and attitudes towards women's roles in relation to their parents' child-rearing practices, needs, and attitudes towards women's roles. These variables were rated by 67 working and 48 nonworking women on three sets of scales, each set composed of items reflecting instrumental (I) and expressive (E) orientations. A single score for each set of scales reflected the balance between the sum of the I and E ratings, or (I-E). In 10 of 13 possible correlations, the subjects' I-E needs and attitudes towards women's roles were significantly related to their parents' I-E child-rearing practices, needs, and attitudes towards women's roles. The work status of the subjects was significantly related to their own I-E needs, to their own and their husbands' attitudes towards women's roles, and to whether their mothers worked.
