Parental correlates of Rorschach human movement responses in children.

The meaning of the human movement response (M) to inkblot stimuli was explored in terms of correlations between children's M productions and the attributes of their parents in 119 familes. M scores were available for the family members; and for each parent there were also measures of personality, values, and childrearing attitudes. A number of the parent-child correlational patterns were congruent with Rorschach's theories concerning the significance of M.     

Fusion frequency as a function of number and phase of binocular stimuli

The relation of fusion hertz to the number of pulses in a train was explored under three conditions: monoptically, dichoptically inphase, and dichoptically antiphase. All three conditions show an increase in fusion hertz as the number of pulses in the stimulating train increases. Over the range of pulse numbers investigated, fusion hertz varies principally with the number of pulses delivered to one eye regardless of the stimulating condition of the other eye.     

Influence and Selection In the Friend-adolescent Relationship: Findings from Studies of Adolescent Smoking and Drinking1

The importance of friend influence as a determinant of adolescent behavior has primarily been inferred from research that has repeatedly demonstrated the behavior of friends to be similar. Homogeneity among peers, however, could also be due to a selection process whereby adolescents choose and keep friends whose behavior is similar to their own. Most previous studies have used cross-sectional designs that cannot delineate the source of peer homogeneity; this study employed sociometric data from longitudinal research on adolescent smoking and drinking to separate and examine the selection and influence processes. Although the findings indicate some support for the friend influence model, the acquisition hypothesis from the selection model accounts for substantially more of the adolescent-friend relationship. The implications of these results for past and future research concerning the role of peers in adolescence are discussed.     

Field independence and simultaneous processing in preschool children

The present study examined the relations between field independence and simultaneous processing of preschool children as measured by the Preschool Embedded Figures Test (PEFT) and subtests from the Kaufman Assessment Battery for Children (K-ABC), respectively. Data partially supported the assumption that field-independent children would perform significantly better on simultaneous processing tasks in general. Significant age and sex differences on field-independence/field-dependence and simultaneous-processing abilities were found among the embedded figures task and selected portions of the K-ABC. Analysis of embedded figures further indicated age differences, but no significant sex differences.     

Field test of the Cognitive Interview: enhancing the recollection of actual victims and witnesses of crime

The Cognitive Interview was tested in the field to enhance the recollection of actual victims and witnesses of crime. The technique is based on laboratory-tested principles of memory retrieval, knowledge representation, and communication. Seven experienced detectives from the Metro-Dade Police Department were trained to use the technique and were compared with 9 untrained detectives. Before and after training, all detectives tape-recorded interviews with victims and witnesses of crime. The trained detectives elicited 47% more information after than before training, and 63% more information than did the untrained detectives. Overall collaboration rates (94%) were extremely high and were equivalent for pre- and posttrained interviews. Because the Cognitive Interview reliably enhances memory and is easily learned and administered, it should be useful for a variety of investigative interviews.
