The effect of enactment upon sentence imitation in preschool children

Preschool children imitated two matched lists of sentences varying in length, in syntactic complexity, and in semantic complexity. Sentences on one list were acted out with toys prior to imitating them. For 3-year-olds, enactment increased retention of all sentential variables: number of words, number of frames, number of propositions, and syntax. For children younger than 3 years, enactment increased only the number of words retained, while for children older than 4 years, enactment had a minimal effect on all sentential variables. In a second experiment, prior enactment had long-term effects on the degree to which children's spontaneous stories about the toys resembled the previous sentences that they had been given to imitate. Long-term effects, however, did not extend to retention of syntax. Enactment appears to increase both young children's interest in a sentence imitation task and the amount of semantic encoding in which they engage. Its effect, however, is mediated by the degree of mastery of relevant linguistic rules.Some of these data were presented at the Biennial Meeting of the Society for Research in Child Development, Detroit, April 1983. The authors would like to thank Lorraine Chiasson, Judith Codd, and Susan Saba for their assistance with the data analysis.     

Protecting Sexual Minority Youth from Research Risks: Conflicting Perspectives

We describe the dilemmas we encountered in the informed consent process for an HIV prevention project targeting Black gay, bisexual, and non-gay identified young men. We highlight the complexities of applying informed parental consent procedures to sexual minority youth and identify some of the challenges that researchers who work with sexual minority youth face when they must balance the needs and rights of this population against the needs and rights accorded to parents by federal guidelines for protecting minor participants in research.     

The effects of a seatbelt-gearshift delay prompt on the seatbelt use of motorists who do not regularly wear seatbelts

A seatbelt-gearshift delay was evaluated in two U.S. and three Canadian vehicles using a reversal design. The seatbelt-gearshift delay required unbelted drivers either to buckle their seatbelts or to wait a specified time before they could put the vehicle in gear. After collecting behavioral prebaseline data, a data logger was installed in all five vehicles to collect automated data on seatbelt use. Next the seatbelt-gearshift delay was introduced. The results showed that the delay increased all 5 drivers' seatbelt use, and that the duration of the delay that produced relatively consistent seatbelt use varied across drivers from 5 to 20 s. When the device was deactivated in four of the five vehicles, behavior returned to baseline levels.     

Dissociating mental transformations and visuo-spatial storage in working memory: evidence from representational neglect

A study is reported of visuo-spatial working memory in two individuals suffering from a cognitive deficit known as unilateral spatial neglect, and seven healthy control participants. Both patients have difficulties reporting details on the left side of imaged representations, and one has an additional difficulty with perceptual input to the left of his body midline. All participants were asked to report the location and identity of objects presented in novel 2 x 2 arrays that were either present throughout or were described orally by the experimenter, with no visual input. On half of the trials, the report was to be made from the opposite perspective, requiring 180 degree mental rotation of the mentally represented array. The patients show an impaired ability to report details from the presented or the imagined left, but had no difficulty with mental rotation. Results point to a clear separation between the processes of perception and those of visuo-spatial working memory. Results also suggest that the patients might be suffering from damage to the system used for holding visuo-spatial representations rather than a difficulty with attending to elements of that representation.     

Sociocultural expectations of attractiveness for males

Sociocultural expectations of attractiveness for women have been studied extensively, but little research has focused on this topic with males. Using the two most popular men's fashion magazines (GQand Esquire), this study examined article and advertisement content as well as male models' body sizes to determine the extent to which men have received messages from the media on how to behave (e.g., diet, exercise) and look over a 32 year period (i.e., 1960–1992). Linear trend analyses revealed that the number of messages concerning physical fitness and health have increased as has the general popularity of health and fitness activities. Messages concerning weight and beauty, however, have declined since the late 1970s. In spite of these changes, measures of male models' body sizes have not changed significantly since the 1960s. These findings are discussed in the context of the sociocultural approach to eating disorders and recommendations for future research are provided.     

Increasing recycling in office environments: The effects of specific, informative cues

We investigated the effects of prompts on the recycling behavior of approximately 217 faculty, staff, and graduate students in two academic departments of a large university. During the intervention, two signs were posted in each department. One sign prompted recycling (posted above the recycling receptacle), and the other sign prompted proper disposal of trash (posted above the trash receptacle). Results of a multiple baseline design across the two departments indicated that the sign prompt increased recycling behavior. Installation of the sign prompts in close proximity to receptacles in Department A resulted in a 54% improvement over baseline. Posting of sign prompts over containers 4 m apart in Department B resulted in a 17% improvement, whereas positioning the signs and receptacles in close proximity resulted in a 29% improvement over baseline.     

Personality characteristics and profiles of employed and outplaced executives using the 16PF

This article examines the psychological profiles of recently terminated executives. The 16PF was used to explore the personality characteristics of outplaced executives. It hypothesizes that recently terminated executives have fundamentally different personality profiles than those of employed executives. The personality profiles of recently terminated executives were compared to personality profiles of a normative group of employed business executives and the personality profiles of a group of executives terminated in 1982. Results indicated that recently terminated executives are identifiable as statistically different from employed executives on 4 of the 16 personality factors. There was no statistical difference between recently terminated executives and the 1982 sample, however, recently terminated executives demonstrated fewer discrepancies from employed executives. Outplacement firms and psychologists working with recently terminated executives need to assist their clients in exploring and modifying these personality profile differences.     

Group-as-a-whole concepts and the therapeutic milieu on the inpatient psychiatric unit

This paper focuses on large group process on the inpatient psychiatric unit. General systems theory and group-as-a-whole concepts are used to understand the dynamics of the therapeutic milieu. Using this information as a tool, the therapist can make various interventions on an individual and group level that will help patients understand and deal with their own psychopathology. Another benefit of this process is that it will develop a community on the psychiatric unit where patients help each other to get well. Three clinical examples are used to illustrate the relevance of this concept. With the advent of short-term psychiatric hospitalization, the therapeutic milieu has shown a drastic decline. Emphasis has been placed on the individual as opposed to the group and a valuable therapeutic tool has been lost. Using a group-as-a-whole concept can help reverse this trend and make the milieu on the inpatient psychiatric unit instrumental in the recovery of the patient.
