Nature of intellectual development of Punjabi children

This research was planned to probe into the nature of cognitive development of four groups of Punjabi children. Children aged 10 to 11 years, belonging to four sub-cultural groups (mainly based on caste) were randomly selected from six primary schools. Following our previous research in this field (Ghuman, 1975) two major hypotheses were set up: (1) The professional group (mainly based on high castes) would be significantly better on a range of cognitive tasks than the other three groups; (2) The Harijans (the lowest caste) would be the most field-dependent group. All the children were tested on a battery of Piagetian tests, a Number test, WISC Block Design and the Coloured Progressive Matrices. The data were analysed by the analysis of variance and t-test techniques. Both the hypotheses were supported. Children's responses on the Piagetian tests were analysed in greater detail and an attempt is made to relate the performance of the children to their social and educational experiences.     

Sexual arousal and interpersonal evaluations

In an attempt to reconcile conflicting results concerning the effects of sexual arousal on interpersonal evaluations, hypotheses based on adaptation level, arousal-need gratification, and labeling of arousal explanations were tested. The variables of sexual arousal, technique of stimulus material presentation, physical attractiveness of the original stimulus female, and physical attractiveness of the final target person being judged were manipulated in a 2 × 2 × 2 × 2 design. A significant three-way interaction (Arousal × Stimulus Attractiveness × Target Attractiveness) obtained on all measures of interpersonal evaluation was interpreted as supporting a labeling of arousal explanation. It is suggested that subjects first interpret their arousal as being caused by their attraction toward the stimulus person. The characteristics of the stimulus person then become a factor used by subjects when they subsequently make judgments of target females. The adaptation-level and arousal-need gratification hypotheses were not supported.     

The effect of punishment and reinforcement procedures on a stutterer's factor II avoidance response

The purpose of this clinical experiment was to investigate the manipulability of a Factor II avoidance response (arm movement). The substantive hypothesis under test was that its suppression would be enhanced by repeated punishment sessions. During the first of nine therapy sessions response-contingent negative stimulation was not delivered. In the next five, after a base-rate period, “wrong” was made consequent upon the target response. In each of these sessions the suppression of arm movement was apparent. However, the magnitude of the suppression decreased from session to session. Evidently, the continued use of punishment did not enhance suppression. Because of this finding procedural changes were introduced in the next three therapy sessions. Verbal praise was added as a consequence of increasingly stringent omission criteria and three consecutive units of praise led to time-out from the reportedly fatiguing task of continuous speech. A marked reduction and then complete extinction resulted. Moreover, learning was evidenced since the frequency of arm movement lessened in the base-rate period of each session.     

A method for the preparation of audio tapes for dichotic listening research

A simple method for producing audio tapes with temporally synchronized messages is described. The duration and spacing of words can be precisely controlled. This method requires a minimum of elaborate equipment, yet synchronization is very accurate with highly intelligible speech.     

Treatment of obsessive-compulsive patients: The contribution of self-instructional training to the effectiveness of exposure

Fifteen obsessive-compulsive patients were given treatment consisting of ten sessions of gradual exposure in vivo. For half of the patients gradual exposure in vivo was preceded by self-instructional training.Treatment resulted in significant improvement on anxiety and avoidance scales, Leyton Obsessional Inventory, Self-rating Depression Scale and on ratings for anxious mood and depression. Neither the post-test nor the follow-ups 1 month and 6 months later indicated a difference between the effects of the two conditions. Self-instructional training did not enhance the effectiveness of gradual exposure in vivo.     

APPLICATION OF A SOCIAL SKILLS TRAINING PROGRAM IN THE MODIFICATION OF INTERPERSONAL DEFICITS AMONG RETARDED ADULTS: A CLINICAL REPLICATION

Six mentally retarded adults, equally divided into two treatment groups, were provided with individualized social skills training programs. Treatment, evaluated via a multiple-baseline design strategy, was sequentially and cumulatively applied across target behaviors over a four-week intervention period. Behavioral observation probes and social validation measures served as the primary dependent variables. Results indicated that (a) treatment was effective for virtually all behaviors across all subjects, (b) improvements occurred for both training and generalization scenes, and (c) behavioral performance was maintained one month following the termination of treatment.     

THE EFFECTIVENESS OF INTERPERSONAL SKILLS TRAINING ON THE SOCIAL SKILL ACQUISITION OF MODERATELY AND MILDLY RETARDED ADULTS

Sixteen moderately and mildly retarded adults were selected from a group residential facility and randomly assigned to experimental and control groups. The experimental group received a 12-session interpersonal skills training program consisting of instruction in the following areas: (1) Introductions and Small Talk, (2) Asking for Help, (3) Differing with Others, and (4) Handling Criticism. The social skills instructional package included verbal instruction, modeling, role playing, feedback, contingent incentives, and homework. As a result of this training program, moderately and mildly retarded adults acquired new social skills as evidenced by performance on a situation role play assessment. These gains generalized to untrained role play situations but did not result in significant group differences when assessed in a more natural setting (i.e., local grocery store).     

The location of superfactors P, E and N within an unexplored personality factor space

Two questionnaires designed by Howarth (HPQ, APF2) whose factor space in unexplored and the EPQ (Eysenck) were jointly scale factored on 79 subjects, under the hypothesis that Eysenck's superfactors of P, E, and N should be represented as major influences in the resultant factor structure. A prinicipal component analysis yielded 7 factors from 24 by the Kaiser-Guttman and Scree Test, these 7 being rotated to a maximum simple structure by the Direct Oblimin procedure. Although failing to satisfy Bargmann's test of simple structure, this solution was accepted as adequate, noting the deficiencies og Bargmann's test and the efficiencies of the rotation method used. Within the 7 factor solution, P, E, and N were seen to be located as factor numbers 2, 3 and 1, respectively. One interesting detail is that a sociability primary loaded with an impulsivity primary on the Extraversion factor contrary to Guilford's (1977) arguments for the independence of these primaries. It is concluded that Eysenck's assertion of the enduring stability and breadth of the PEN factor triad has been upheld.     

Television viewing and the learning of sex-role stereotypes

This study was designed to determine the relationship between the amount of time children spend watching television and their knowledge of adult sex-role stereotypes. Males and females in grades 1, 3, 5, and 7 who were classified as heavy television viewers (25 or more hours per week) or light viewers (10 or less hours per week) both at the time of the study and 15 months previously were administered the Sex Stereotype Measure, an instrument designed to determine children's awareness of stereotyped sex-role perceptions held by adults. Heavy viewers were found to have more stereotyped perceptions than light viewers. A significant interaction effect indicated that among low viewers the perception of male stereotypes steadily declines with increasing age; among heavy viewers, stereotypic responses to male items are maintained with increasing age. No comparable interaction effect was obtained for perception of female stereotypes. The role of interaction with live models in breaking down stereotypic perceptions of males is discussed.A modified version of this paper was presented at the meeting of the Society for Research in Child Development, Denver, April 1975.
