Effects of warm and neutral models on the attention of observational learners

The study was conducted to examine observers' attention to adults following warm and neutral interactions with them. Forty-two preschool and 36 third grade girls interacted with a pair of female models in one of three treatment conditions in which models were, respectively, warm and neutral, neutral and neutral, or warm and warm. Subiects then witnessed the models play a picture-preference game and were asked to recall the models' responses. Analyses of the children's overt attention to the models' responses revealed a greater attention to a warm model when in the presence of both a warm and neutral model and less distraction by nonsocial stimuli when at least one warm model was present. A significant positive correlation was obtained between attention to and recall of the models' responses.     

A theoretical comparison of list scanning models

Eight specific list scanning models are developed and relationships between predictions of contrasting models (serial versus parallel search, self-terminating versus exhaustive processing) are investigated. All models assume that items contained in a list are uniquely defined by specific features, and that the only process by which two items may be tested for equality is to compare corresponding features. All models predict RT to be linearly related with list length when no subject errors occur. With errors, some models predict theoretical nonlinearity but sample calculations indicate that deviation from linearity is slight in many cases. The importance of coding strategy is also discussed.     

An examination of disciplinary procedures with children

In Experiment I the effect of the contingent application of negative attention (a verbal reprimand plus a brief period in which the authority person glares intently at the child) and repeated commands on the noncompliant behavior of children was examined. Thirty-two mother-child pairs served as subjects. The results indicated that negative attention decreased noncompliance whereas repeated commands did not. In Experiment II the effectiveness of negative attention, isolation, ignoring, and a combination of procedures (the alternate use of isolation, ignoring, and negative attention with the same subject) in reducing noncompliance and maintaining it at a low level during a recovery period was examined. Twenty-eight mother-child pairs served as subjects. The results indicated that each of the four disciplinary procedures reduced noncompliance. However, negative attention was associated with less off-task behavior than the isolation and combination procedures when discipline was being imposed and a lower level of noncompliance than ignoring during recovery, whereas the combination condiiton was the only procedure that maintained noncompliance during recovery at the treatment level.     

An examination of methods for producing relaxation during short-term laboratory sessions

Reductions in psychological and physiological correlates of tension produced by various muscle relaxation training techniques were examined during a short-term laboratory session. Two studies are described involving a combined total of one hundred subjects receiving either abbreviated progressive relaxation, visual, auditory, or tactile electromyographic (EMG) biofeedback procedures. The Anxiety Differential was administered before and after the laboratory session. Heart rate, respiratory rate, skin conductance, systolic blood pressure, and frontalis and dominant forearm extensor EMG measures were obtained before, during, and after administration of relaxation training. Results indicated feedback in the tactile modality to produce overall reductions in tension comparable to those produced by progressive relaxation. Overall reductions in tension displayed by both progressive relaxation and tactile feedback were generally greater than reductions shown by visual or auditory feedback procedures. Interpretations suggest that certain forms of EMG feedback may offer an alternative to progressive relaxation techniques for producing short-term reductions in tension. Feedback modality is further indicated as a potentially important variable during relaxation training using the EMG feedback technique.     

THE EFFECTS OF SOCIAL PUNISHMENT ON NONCOMPLIANCE: A COMPARISON WITH TIMEOUT AND POSITIVE PRACTICE

The effects of social punishment, positive practice, and timeout on the noncompliant behavior of four mentally retarded children were assessed in a multitreatment withdrawal design. When programmed, the experimental procedure occurred contingent on noncompliance to experimenter-issued commands. Commands were given at 55-sec intervals throughout each experimental session. The results showed (1) lower levels of noncompliance with social punishment than with the positive-practice or timeout conditions, and (2) that relatively few applications of social punishment were required to obtain this effect. The advantages of social punishment over other punishment procedures, considerations to be made before using it, and the various aspects of the procedure that contribute to its effectiveness were discussed.     

Clause structure of sentences and speech processing

Listeners heard narrative stories in segments 20-60 sec long, and wrote their immediate recall for the most recent speech in each segment. Segments ended in four ways: there was a main clause alone, a subordinate clause alone, a main clause preceding a subordinate clause, or a subordinate clause preceding a main clause. Only these final sentences were well recalled. Of these, single-clause sentences were recalled best and two-clause sentences with main-subordinate clause order were recalled worst. An interaction obtained between clause position and function suggests that processing may be delayed when sentences fall to begin with main clauses.     

Social communication patterns of attention-deficit-disordered boys

This study was designed to compare the social communication patterns of attention-deficit-disordered (ADD) and normal boys. This was accomplished by employing a TV Talk Show social role-playing procedure in which the task required different strategies for the roles of host and guest. Groups of ADD and normal elementary-age boys were formed, and each boy was paired with a normal classmate. Measures of communication competence were coded from videotapes made of subject and partner social interactions while performing both roles. Results indicated that the ADD boys, in contrast to the control group, failed to modulate their social communication behaviors as task demands shifted. Additionally, the behavior of the ADD boys resulted in their normal partners' altering their response patterns in order to maintain the equilibrium in the dyadic interaction. These results suggest that the social behavior of ADD children is relatively independent of environmental requirements and may contribute to the inappropriate responding of others.
