An investigation of persuasion and sentencing severity with mock juries

The extent to which the personal characteristics of individual mock jurors affect participation and influence with other jurors within the deliberation process was the focus of this investigation. A predeliberation locus of control measure, along with two conditions of jury composition (heterogenous vs homogenous with respect to the locus of control measure) were used to investigate interactions among sentencing severity, persuasiveness in deliberation, and demographic characteristics among 96 jurors. Results indicated that group sentences were significantly more severe than predeliberation sentences and that postdeliberation shifts were significantly more pronounced for the heterogenous juries than for the homogeneous juries.     

An examination of the assumptions in the demand characteristics thesis: With special reference to the Velten mood induction procedure

We examine the assumptions that are generally made when it is argued that a set of experimental findings is due to the subjects' compliance to demand characteristics. There is little evidence supporting many of these assumptions: that many experimental subjects disbelieve the cover story given them, that they are eager to search for clues revealing the study's actual purpose, that they are highly sophisticated in making inferences on the basis of any cues they detect, and that they are motivated to confirm the experimenter's hypothesis, whether to aid science or to make their participation meaningful. Our argument is applied to studies contending that results obtained with the Velten mood induction procedure are substantially affected by demand compliance. In particular, we question an assumption often made by these studies and point out the following: A demonstration that subjects can accurately mimic the reactions of participants given the Velten statements when they are explicitly asked to do so, or when they are instructed how to simulate these reactions, does not necessarily mean that subjects will voluntarily engage in such accurate play-acting when they are not asked to engage in this make-believe. Research has also noted that a number of Velten-induced reactions are probably too subtle to have been deliberately faked.     

Validating a brief pupil evaluation inventory

A shortened version of the Pupil Evaluation Inventory (PEI) was evaluated. The shortened version consists of nine items and was administered to 381 third-, fourth-, and fifth-graders in Chicago area Catholic schools. A factor analysis revealed the same factor structure as the original measure. Correlations with other sociometric ratings and the Achenbach Teacher Report Form were moderate to strong. A series of ANOVAs was used to compare the factors of the PEI to the five social status groups calculated from a peer nominations measure, and significant differences were found. Rejected children received higher scores on Aggression and Withdrawal than any other group, and popular children scored significantly higher on Likability.Special thanks to Loisa Bennetto for reading the many drafts of this paper and to Jay Johnson, who helped with some of the initial analyses.

The dilemma of primary prevention in mental health services: Rationalize the status quo or bite the hand that feeds you

That primary prevention has been ‘inappropriately marginalised’ is seen to be an inevitable outcome of reliance on government support. Policy makers and service providers can never be expected to give prevention a higher priority than direct service. Preventionists have developed two strategies for doing their work. One, based on the logical positivist ideal, seeks specific causal models for specific disorders. This sort of prevention research, while it will always remain less well funded than direct services, tends not to challenge the status quo belief in individual responsibility, or the acceptable methods of mainstream science, and thus will tend to be more acceptable than other forms of prevention research and services. An alternative, based on a social constructivist paradigm engages in social action research through collaboration with a variety of grass roots organizations and people outside the mainstream of power. This latter approach, brings to preventionists ideas from feminists, ethnic minority leaders, neighborhood organizers, and self and mutual help group leaders. It is a sensible way to use the resources available to those professionals interested in social change oriented prevention.     

Selective processing of food,weight, and body-shape words in nonpatient women with bulimia nervosa: Interference on the Stroop task

The study investigated whether the Stroop interference effect could be found in nonpatients with a self-report consistent with a diagnosis of bulimia nervosa. The nonpatient bulimic group showed significantly more interference to disorder-specific words (food, weight, and body shape) than to control words. The two nonpatient comparison groups, a depressed-nonbulimic group and a nonbulimic-nondepressed group, showed no interference. These results indicate that nonpatients with bulimia nervosa can be used to test various models of the cognitive and emotional processes involved in bulimia nervosa with the modified Stroop task. Methodological issues in the use of the computerized Stroop task with clinical populations are also noted.     

Spare the rod and spoil the child?

The four papers which follow were originally presented at a research conference at the University of North Carolina, Chapel Hill, on the use of discipline by primary caregivers. The use of corporal punishment in child discipline was discussed extensively. There was no consistent opinion among the authors about whether corporal punishment should be totally discouraged or whether such discipline had its place in the array of practices used by parents. Data supporting both points of view were presented and it was recommended that classification schemes of disciplinary practices include, in addition to a typology, some indications of the harshness of the punishment, the way in which it is administered and important contextual aspects.     

Pastoral care and AIDS: Assessing the stress and satisfaction from caring for persons with AIDS

Members from religious communities in New York City (17 men, 8 women) who volunteer pastoral care to persons with AIDS completed and returned through the mail the (AIDS) Caregiver Scale and the Attitudes toward AIDS Scale. Results indicated that satisfaction from providing care was related to pastoral training, an understanding of the spiritual nature of death, and a positive attitude toward persons with AIDS. Self-reported stress from providing care was inversely related to pastoral training to deal with death. The pastoral volunteers also reported greater satisfaction and lower stress from caregiving than volunteer buddies from upstate New York.     

Light and dark adaptation of visually perceived eye level controlled by visual pitch

The pitch of a visual field systematically influences the elevation at which a monocularly viewing subject sets a target so as to appear at visually perceived eye level (VPEL). The deviation of the setting from true eye level averages approximately 0.6 times the angle of pitch while viewing a fully illuminated complexly structured visual field and is only slightly less with one or two pitched-from-vertical lines in a dark field (Matin & Li, 1994a). The deviation of VPEL from baseline following 20 min of dark adaptation reaches its full value less than 1 min after the onset of illumination of the pitched visual field and decays exponentially in darkness following 5 min of exposure to visual pitch, either 30° topbackward or 20° topforward. The magnitude of the VPEL deviation measured with the dark-adapted right eye following left-eye exposure to pitch was 85% of the deviation that followed pitch exposure of the right eye itself. Time constants for VPEL decay to the dark baseline were the same for same-eye and cross-adaptation conditions and averaged about 4 min. The time constants for decay during dark adaptation were somewhat smaller, and the change during dark adaptation extended over a 16% smaller range following the viewing of the dim two-line pitched-from-vertical stimulus than following the viewing of the complex field. The temporal course of light and dark adaptation of VPEL is virtually identical to the course of light and dark adaptation of the scotopic luminance threshold following exposure to the same luminance. We suggest that, following rod stimulation along particular retinal orientations by portions of the pitched visual field, the storage of the adaptation process resides in the retinogeniculate system and is manifested in the focal system as a change in luminance threshold and in the ambient system as a change in VPEL. The linear model previously developed to account for VPEL, which was based on the interaction of influences from the pitched visual field and extraretinal influences from the body-referenced mechanism, was employed to incorporate the effects of adaptation. Connections between VPEL adaptation and other cases of perceptual adaptation of visual direction are described.
