Effects of inadmissible Evidence on the Decisions of Simulated Jurors: A Moral Dilemma

In a 2 × 3 design, simulated jurors received either weak or strong evidence against a defendant in a murder case. Within each evidence condition, subjects were given either additional evidence ruled admissible, additional evidence ruled inadmissible, or no additional evidence. Results indicated that ( a ) jurors were biased by inadmissible evidcnce in the weak-evidence but not in the strong-evidence condition, ( b ) strong evidence resulted in more guilty verdicts than did weak evidence, ( c ) confidence in verdict was influenced by strength of evidence, and ( d ) confidence of guilt was positively correlated with severity of punishment. Implications of the results are discussed within the context of the judicial process.     

Hypermnesia for pictures: Incremental memory for pictures but not words in multiple recall trials

Two studies are reported on multiple forced recall following a single visual presentation of a sequence of pictures or words. In both experiments, a hypermnesic memory function (in which performance improved with repeated recall) was obtained for pictures, while a flat, nonincremental function was obtained for words. Interpolation of intervals of thinking between recall trials further enhanced hypermnesia for pictorial items. Retrieval, whether overt (recall trials) or covert (thinking), apparently produces increased net recovery of pictures but not words.     

TRAINING GENERALIZED RECEPTIVE PREPOSITIONS IN RETARDED CHILDREN1

Three retarded children were trained, using prompting and reinforcement procedures, to respond correctly to three categories of prepositional requests: “put the___ next to the___”, “put the___under the___”, and “put the___on top of the___”. Training sessions were alternated with probe sessions throughout the study. During training, a child was trained to respond to one request (e.g., “put the doll next to the cup”); during probing, the child was tested for generalization of this training to untrained requests. Responses to untrained requests were never prompted nor reinforced. The results showed that, as requests from one category were trained, the children's responses to the untrained requests of that category became increasingly correct. As discriminations among two or more categories were trained, the children's responses to the untrained requests of those categories also became increasingly correct. Thus, the methods employed appear to be successful in training generalized receptive discrimination among prepositional categories and possibly can be utilized in training other generalized receptive language skills.     

The effects of retention interval on preschool children's short-term memory of verbal items

The short-term recall of word-triads was tested, comparing retention over three types of intervals within 24 preschoolers. Retention was significantly lower in the 16 sec unfilled interval condition than in the immediate test condition. This result, predicted from preschoolers' rehearsal deficiency, differs from those obtained in previous adult and child studies. A filled interval condition, requiring irrelevant verbal activity during the 16 sec period, significantly reduced recall from that of the unfilled interval condition. Recognition of the word items on a subsequent recognition test was greater than chance and was not affected by interval condition. This suggests that the condition effects in short-term recall did not disrupt the long-term storage of the items.     

The dimensions of career and work orientation in college women

The purpose of this study was to clarify the meaning of the construct, career orientation. Fourteen presumed measures of career orientation as well as Super's Work Values Inventory were administered to college women. Analysis of the relationships among these variables identified two relatively independent clusters. The first cluster most closely approximated the usual definition of career orientation. Career-oriented women were found to be highly career motivated and perceived the career role as primary in their adult lives. The second cluster was called work orientation. This orientation characterized women with well-defined occupational aspirations who placed a high value on both the career role and marriage-family responsibilities in their future. Work-oriented women tended to choose traditionally feminine occupations in contrast to the career-oriented women whose aspirations included higher level and less traditional occupations.     

Are the fruits of research available to all? The effects of sex and academic rank on reprint-sending behavior

There is considerable evidence in the psychological literature that perceived status often has a major effect on behavior. The primary purpose of the present study was to examine the effects of two status variables in an academic setting by monitoring reprint-sending behavior. Reprints were requested from 1,200 authors of psychological articles by men and women of varying academic rank. Neither sex nor academic rank of requester had any significant effect on the total number of responses returned. However, male requesters received responses significantly faster than did female requesters. In addition, subsequent analyses indicated that reprint requests were more likely to be honored by male authors than by female authors.     

Talking about unemployment with school-leavers

Research is reported concerning the views of a variety of professionals as to appropriate ways of talking about unemployment with 16-year-old school-leavers. Preparation in schools for the possibility of unemployment is discussed, as well as issues for those in contact with young people without a job after they leave school. The ways in which professionals talk to young people about unemployment appear to vary substantially. The findings suggest that in adopting a particular approach a professional will be influenced by his beliefs about the labour economy, by his perceptions of young people's wants and needs, and by his own capacity to cope with the feelings involved in re-examining his role in relation to unemployed young people.     

ACQUISITION OF EXPRESSIVE SIGNING BY AUTISTIC CHILDREN: AN EVALUATION OF THE RELATIVE EFFECTS OF SIMULTANEOUS COMMUNICATION AND SIGN-ALONE TRAINING

Two methods of training autistic children to use manual signs were compared. Two children, one mute and one capable of some verbal imitation, were taught to use signs as expressive labels for pictures of objects. Using an alternating treatments design, speed of sign acquisition was compared across two training conditions in which signs were presented either accompanied by, or without, the corresponding verbal label. In both conditions, the training procedure incorporated reinforcement, modeling, prompting, fading, and stimulus rotation. The efficacy of training in both treatment conditions was demonstrated by the use of a multiple baseline control across signs, but no clear differences in acquisition speed across conditions were apparent. Posttests conducted to assess stimulus control of signing, and learning of verbal labels when these were present in training, showed that the behavior of the imitative, but not the mute, child was controlled by the verbal stimuli. The implications of the results both for understanding deficits characteristic of autistic children and for developing appropriate language training procedures are discussed.
