Mentally retarded individuals outperform college graduates in judging the nonconservation of space and perimeter

Most adults of average and superior intelligence incorrectly assume that in a two dimensional figure two attributes, area, and perimeter, are locked in a fixed relationship such that if one remains unchanged so does the other. Consequently, when they correctly conserve one attribute during shape transformation, they incorrectly conserve the other. Mentally retarded individuals assume no such fixed relationship but depend exclusively on perceptual information. Although this dependence adversely effects their judgment of conservation, it allows them to correctly judge the changed state of the nonconserved attribute.     

Strategies in the recall of clusterable lists

The present study assessed the effectiveness of a multi-session training aproach intended to teach mildly retarded adolescents to discover and utilize categorical list structure. The performance of a group of trained retarded individuals was compared with that of another group of retarded individuals who had simply received practice with the training materials. The performance of both retarded groups was evaluated relative to that of a group of equivalent-CA normal adolescents. Recall transfer with a new word list was indicated by the finding that trained retarded subjects achieved a criterion of perfect recall in fewer trials than untrained retarded subjects. Differences in the use of categorization strategies by normal and retarded subjects were interpreted in the light of the automatic-controlled processing distinction of Schneider and Shiffrin (1977).     

Parental defense style and child competence: A match-mismatch hypothesis

This study sought to explore the possible relationship between parental style of psychological defense and children's social competence in 50 families in which one parent had been hospitalized for a psychiatric disorder. Based upon a formal analysis of the logical transformations inherent in various defense mechanisms, three levels of complexity of defenses were identified, along with a counterpart set of cognitive operations necessary for decoding these defense levels. It was hypothesized that children lacking the requisite cognitive skills to grasp the logical complexities of their disturbed parent's primary mode of psychological defense would be less socially adjusted and judged less competent than children who could understand the defensive transformations of their parent. The results suggested that children who, due to their cognitive immaturity, are potentially     

Influence of a televised model's vocalization pattern on infants

To assess the influence of a televised model's vocalizations on the vocal patterns of infant viewers, 32 infants at 6 months of age were presented either a televised adult model repeating a novel phoneme pattern (/ba/ba/ba/ba) or a control televised presentation of adult conversation selected from typical daytime programming. Sequential analyses of infant vocalizations revealed that infants exposed to the televised model altered their vocalization pattern, as indicated by a significant increase over base line levels in their production of a patterned series of discrete vocalizations. Infants exposed to the televised conversation showned no increase in this pattern of vocalization, and none of the infants in the study produced the novel phoneme (/ba/). The results indicate that televised presentation of discrete, repeated vocalizations can have an influence on the vocalization pattern of infants. The potential role of television in infant development is discussed.     

Measuring rationality independent of social desirability

The development of a test to measure Elli's concept of rationality is described. In the first study discussed, a 58-item test is developed to measure rationality, and the reliability and convergent validity of the test is described. In a second study, the discriminant validity of the test is examined. An attempt is also made to reduce social-desirability content in the test by eliminating items most highly correlated with a Social Desirability Scale. The final 44-item test is found to be high in both reliability and validity. The factor structure of the test is also examined.     

The good,the bad and the mad: Response bias in self-report measures

This study set out to examine the susceptibility of five extensively used, self-report measures to response set bias. Subjects were requested either to fake good, (give a good impression), fake bad, (give a bad impression), fake mad, (give an impression of mental instability) or respond honestly. Subjects who faked good had significantly higher Extraversion, Lie and Social Desirability scores but lowest Neuroticism, Psychoticism and Social Anxiety scores. Subjects who faked bad had significantly lower Extraversion and higher Psychoticism and Social Anxiety scores. Fake mad subjects scored higher on Self-Monitoring and Locus of Control. Four of the eight scales showed significant differences between subjects faking bad and those faking mad. The results are discussed in terms of questionnaire design and respondent's motivation.     

Interpersonal problem solving: An intervention program for preschool children

The purpose of the present study was to evaluate the effectiveness of an intervention program designed to train preschool children in interpersonal problem solving skills. Forty preschool age children were randomly assigned to an experimental or control group. Experimental subjects were trained in interpersonal problem solving skills for ten weeks, four days per week, for a total of 10–13 hours. Problem-solving skills were assessed at pretest, posttest, and three months after training was completed. Seventy-eight percent of the children who participated in pretest and posttest were tested at follow-up. Results indicated that the experimental group, compared to the control group, showed a significant increase in both cognitive—verbal and behavioral interpersonal problem-solving skills from pretest to posttest and that these changes were maintained at follow-up testing. Discussion focuses on suggestions for future research and implications for applied settings.     

Response-contingent stimulation as a treatment for developmental failure in infancy

An 8-month-old infant with a developmental quotient of $\text{1}\text{1}\text{2}$ months was given response-contingent stimulation using a pressure-sensitive pillow which turned an overhead mobile. The subject learned to control the mobile by kicking the pillow, and concurrently began smiling at both the mobile and her mother for the first time. After mastering three contingencies on arm, head, and leg movement, she displayed what appeared to be a Piagetian coordinated secondary circular reaction, in which one response provided 4 seconds of access to another contingency. Although the subject remains severely retarded, the results suggest that some forms of developmental delay may be treated at least in part as a failure to develop contingency awareness.     

Psychometric characteristics of Chicano and non-Hispanic White children's performance on the preschool inventory

Two studies are reported that independently examined the psychometric characteristics of children's performance on the Preschool Inventory. The sample in Study I consisted of 100 Chicano children tested longitudinally at ages $\text{3}\text{1}\text{2}$ and 4 years. The sample in Study II consisted of 200 Chicano and non-Hispanic White children matched on mothers' schooling level in a cross-sectional design involving two age levels—prekindergarten-age children and children enrolled in kindergarten. Comparisons were made by ethnic group, sex, and age level with regard to item characteristics, internal-consistency reliabilities, test—retest stability, standard errors of measurement, validity, and performance level. Comparisons also were made between the psychometric characteristics of the Chicano children's performance on the Preschool Inventory and the psychometric characteristics reportedly by other investigators for the same instrument administered to children of other ethnic, socioeconomic, and sociolinguistic backgrounds. The results provide impressive evidence of the Preschool Inventory's psychometric strengths and demonstrate that the examined psychometric characteristics of the Preschool Inventory are as exemplary when the test is administered to Chicano children as they are exemplary when it is administered to children of other ethnic backgrounds. Certain limitations of the Preschool Inventory are identified. Recommendations are made regarding possible avenues for future test development efforts.
