Sharing behavior and racial preference in children

Three groups of white children, 43 preschoolers and first-graders, 46 third-graders, and 44 fifth-graders, were asked to choose either a white child or a black child as a recipient of sharing and also as a companion for several social interaction situations ordered for social distance. The preschoolers and first-graders preferred to share and interact socially with the white child. The third-graders and the fifth-graders displayed a weaker preference for the white child over the black child on the sharing task, no preference in situations of high social distance, and a preference for the white child in situations of low social distance. The results from ancillary measures suggested that the choices of the younger children were motivated by a generalized color preference but that the choices of the older children were guided by an awareness of the social meaning of racial categories.The investigation was supported by the Research Advisory Council of East Tennessee State University.     

A longitudinal study of high scorers on the hypomanic personality scale

Former college students (n = 36) identified by high scores on the Hypomanic Personality Scale (HYP; Eckblad & Chapman, 1986) were compared with control participants (n = 31) at a 13-year follow-up assessment. As hypothesized, the HYP group reported more bipolar disorders and major depressive episodes than the control group. The HYP group also exceeded the control group on the severity of psychotic-like experiences, symptoms of borderline personality disorder, and rates of substance use disorders. HYP group members with elevated scores on the Impulsive-Nonconformity Scale (Chapman et al., 1984) experienced greater rates of bipolar mood disorders, poorer overall adjustment, and higher rates of arrest than the remaining HYP or control participants.     

Manipulating smoking motivation: impact on an electrophysiological index of approach motivation.

A chief goal of this research was to determine whether stimuli and events known to enhance smoking motivation also influence a physiological variable with the potential to index approach motivation. Asymmetry of electroencephalographic (EEG) activity across the frontal regions of the 2 hemispheres (left minus right hemisphere activation) was used to index approach motivation. In theory, if EEG asymmetry sensitively indexes approach dispositions, it should be influenced by manipulations known to affect smoking motivation, that is, exposure to smoking cues and tobacco deprivation. Seventy-two smokers participated in this research and were selectively exposed to a smoking-anticipation condition (cigarettes plus expectation of imminent smoking) following either 24 hr of tobacco withdrawal or ad libitum smoking. Results indicated that EEG asymmetry was increased by smoking anticipation and that smoking itself reduced EEG asymmetry. Results also suggested that smoking anticipation increased overall (bihemispheric) EEG activation. Results were interpreted in terms of major theories of drug motivation.     

Reward Allocation by Impartial Allocators to Friend or Stranger Co-workers under Equal and Unequal Ability and Performance

The effects of a relationship variable (friends, strangers), an ability variable (equal, unequal), and a performance variable (equal, unequal) were studied in 40 male and 40 female university students. Eight versions of a hypothetical vignette were prepared to manipulate the eight treatment combinations. After reading an assigned vignette, subjects were asked to allocate $90 between two stranger or friend co-workers. Among other effects, the Relationship by Ability by Performance interaction was significant. The stranger, unequal ability, unequal performance allocations to the lower ability co-worker were significantly higher than the stranger, equal ability, unequal performance allocations, and the stranger, unequal ability, unequal performance allocations were higher than the friends, unequal ability, unequal performance allocations; this difference approached significance (p < .06). The questionnaire data revealed that, despite having favored strangers, the impartial allocators expected strangers to be less satisfied with their distribution than friends with their distribution. In this study, impartial allocators tended to compensate strangers to a greater extent for low performance or ability than friends or, alternatively, were more likely to ignore performance and ability differences between strangers than between friends.     

The effect of organismic disadvantage on allocation behavior in children

Equity theory (Adams, 1965) suggests that when persons are asked to divide a given amount of reward between two other persons, one relatively more disadvantaged than the other at performing a task, they will make allocations that are disproportionate to the two persons' performance levels, giving the disadvantaged person a disproportionately larger share and the advantaged person a disproportionately smaller share of the reward. The theory attributes this effect to the allocator's perception that the disadvantaged individual expended a disproportionately greater amount of effort. A group of third- and fourth-graders and a group of seventh-graders were asked to divide rewards between pairs of children that were described to vary in age (“younger” vs. older) or ability (“unskilled” vs. skilled) or that were the “same” in age and ability and that were described to vary (5 vs. 15, or 0 vs. 20 baskets) or to be equal (10 vs. 10 baskets) in performance on a basketball-shooting task. Unlike the group of third- and fourth-graders, the seventh-graders generally made significantly larger allocations to the disadvantaged individuals (“younger” and “unskilled”) than to the “same” individuals, making the largest allocations under the most discrepant performance condition (0 vs. 20). Overall, the results suggested that the equity principle becomes more salient in children as age increases.     

Examining adversarial growth in illness: The factor structure of the silver lining questionnaire (SLQ-38)

The Silver Lining Questionnaire (SLQ-38) is purported to measure 10 aspects of adversarial growth in illness. To date however, no empirical evidence exists to support this claim. Hence the aim of this study was to investigate the factor structure of the SLQ-38 in a sample of 560 individuals with multiple sclerosis (MS), cancer, cardiac, and renal disease. The results demonstrate that 24 SLQ-38 items can be factored into five subscales: improved personal relationships, greater appreciation for life, positive influence on others, personal inner strength and changes in life philosophy, all of which are in accordance with the literature on adversarial growth. Individuals with MS experienced lower adversarial growth compared to other illness groups. Gender, age and time since diagnosis were unrelated to adversarial growth in illness. The utility of the revised SLQ-38 is discussed along with suggestions for future research on the convergent and divergent validity of this revised instrument.
