Spiritual Coping, Family History, and Perceived Risk for Breast Cancer—Can We Make Sense of it?

Differences in spiritual beliefs and practices could influence perceptions of the role of genetic risk factors on personal cancer risk. We explored spiritual coping and breast cancer risk perceptions among women with and without a reported family history of breast cancer. Analyses were conducted on data from 899 women in primary care clinics who did not have breast cancer. Structural equation modeling (SEM), linear, and logistic modeling tested an interaction of family history of breast cancer on the relationship between spiritual coping and risk perceptions. Overall analyses demonstrated an inverse relationship between spiritual coping and breast cancer risk perceptions and a modifying effect of family history. More frequent spiritual coping was associated with lower risk perceptions for women with positive family histories, but not for those with negative family histories. Results support further research in this area that could influence communication of risk information to cancer genetic counseling patients.     

The development of area discrimination and its implications for number representation in infancy

This paper investigates the ability of infants to attend to continuous stimulus variables and how this capacity relates to the representation of number. We examined the change in area needed by 6-month-old infants to detect a difference in the size of a single element (Elmo face). Infants successfully discriminated a 1:4, 1:3 and 1:2 change in the area of the Elmo face but failed to discriminate a 2:3 change. In addition, the novelty preference was linearly related to the ratio difference between the novel and familiar area. Results suggest that Weber's Law holds for area discriminations in infancy and also reveal that at 6 months of age infants are equally sensitive to number, time and area.     

Dissonance and importance: attitude change effects of personal relevance and race of the beneficiary of a counterattitudinal advocacy

The authors asked or instructed White college students to write an essay advocating a large tuition hike to increase scholarships for either students in general or Black students (yielding low or high racial symbolism, respectively) that would take effect in the near or far future (yielding high or low personal relevance, respectively). Especially when high-choice participants wrote highly compliant (i.e., unqualified) essays, attitude change was greater when the advocacy had either high (vs. low) personal relevance or high (vs. low) racial symbolism. Yet there was no attitude change when both symbolism and relevance were high. They may increase dissonance by making the dissonant elements more important and numerous. The coupling of relevance and symbolism, however, may link the attitude so strongly to personal values and self-concept that attitude change becomes untenable as a mode of dissonance reduction.     

The influence of provocateurs' emotion displays on the social information processing of children varying in social adjustment and age

This study examined the effect of provocateurs' emotion displays on first through fourth graders' social information processing (SIP). Rating and nomination sociometric techniques were used to identify rejected-aggressive, rejected-nonaggressive, average-nonaggressive, and popular-nonaggressive groups. Children viewed videotaped ambiguous provocation situations in which provocateurs' emotion displays were varied systematically. After each vignette, children's recall of story details, attribution of intent, and problem-solving responses were obtained. Half of the children were randomly assigned to a condition where they were asked directly about provocateurs' emotions, and the remaining children were not asked about provocateurs' feelings. Results revealed both developmental and social adjustment differences in SIP. In addition, provocateurs' emotion displays and asking versus not asking about those displays influenced multiple aspects of SIP.     

College students, tattoos, and sexual activity

This research examined the association of having a tattoo and engaging in premarital sexual intercourse. Data gathered from a convenience sample of 450 college students indicated that tattooed respondents were substantively and significantly more likely to be sexually active than nontattooed college students. Tattooed men became sexually active at a significantly earlier age than nontattooed men but no such difference was found between tattooed and nontattooed college women.     

The role of the GABA(A) agonist muscimol on memory performance: reward contingencies determine the nature of the deficit

A matching-to-position (MTP) paradigm was altered to influence the type of associations a rat would use to solve the task. Our main behavioral manipulation was the application of the differential outcomes procedure (DOP). The DOP involves correlating each to-be-remembered event with a distinct reward condition. This procedure results in the development of unique reward expectancies that enhance and guide choice behavior. Such distinct reward expectancies are not formed when either a common or random assignment of reward is used (a non-differential outcomes procedure [NOP]). Intracerebroventricular infusions of the amnestic agent muscimol (GABA(A) agonist) or aCSF were delivered to male rats trained on a delayed MTP task that implemented either the DOP or the NOP. Muscimol impaired performance in a dose dependent fashion in both groups--but the nature of the deficit differed as a function of reinforcement contingencies. Rats trained with the DOP displayed a non-mnemonic delay-independent impairment: performance at all delay intervals was disrupted. In contrast, NOP-trained rats displayed a delay-dependent impairment demonstrating that muscimol can also have memory-disrupting effects. The difference in pattern of impairment appears to be a function of the associations formed during training and the type of cognitive strategies involved in maintaining behavior on a conditional delayed discrimination task when reinforcement contingencies are varied. Thus, these results demonstrate that increasing GABA(A) receptor activation impairs a range of associative and memory functions.     

Instant of chair-rise lift-off can be predicted by foot-floor reaction forces

OBJECTIVE: To develop a predictive model of the lift-off event during chair rise in healthy subjects, using foot-floor reaction forces. BACKGROUND: An important event during chair rise is lift-off from the seat: the transition from the inherently stable three-point contact to the unstable two-point contact. There is no consistent or generally agreed upon method for estimating the time of lift-off when an instrumented seat is unavailable. METHODS: Twenty healthy volunteers were divided into a testing set and training set. Each subject performed repeated chair rise trials at different speeds. Seat-floor and foot-floor forces, recorded with two force platforms, were used to develop a model of the lift-off event. RESULTS: The magnitude of the vertical foot-floor reaction at lift-off (F0VF) was linearly related (R2 = 0.71, P < 0.001) to the peak vertical foot-floor reaction force (FMVF). A linear model was developed for the training group, which enabled prediction of lift-off time for the testing group with an absolute average error of 6 ms (about 1 data frame at 150 Hz). The linear model derived for the entire sample was: F0VF = 28.14 + FMVF * (0.6434). CONCLUSIONS: The lift-off event for healthy subjects performing chair rise can be accurately predicted from foot-floor reaction forces, without requiring an instrumented seat.     

Religious Coping, Psychological Distress and Disability Among Patients with End-Stage Pulmonary Disease

A growing body of literature suggests that individuals who face life-threatening situations turn to religion to help them cope. Religion has been cited as the most frequently used resource to cope with stressful events (K. I. Pargament, 1997). The present study was the first to investigate the religious coping methods of patients with lung disease who are awaiting transplant and to identify which coping methods are associated with distress and disability. The study was an exploratory, cross-sectional analysis of 90 patients with end-stage pulmonary disease who were being evaluated for transplant. Results indicated that religiosity was highly prevalent. Patients employed a combination of religious coping efforts, but mostly used coping methods considered positive. Patients with late-onset pulmonary diseases used religious coping strategies more frequently than patients with cystic fibrosis. Hierarchical regression analyses identified a subset of religious coping strategies that predicted 27%, 14%, and 34% of the unique variance in depression, overall disability, and psychosocial disability, respectively.     

The effects of hippocampal lesions on learning, memory, and reward expectancies

The hippocampus appears to be critical for the formation of certain types of memories. Hippocampal-lesioned animals fail to exhibit some spatial, contextual, and relational associations. After aspiration lesions of the hippocampus and/or cortex, male rats were allowed to recover for three weeks before being trained on a matching-to-position task. The matching-to-position task was altered to influence the type of cognitive strategies a subject would use to solve the task. The main behavioral manipulation was the reinforcement contingency assignment: Use of a differential outcomes procedure (DOP) or a nondifferential outcomes procedure (NOP). The DOP involves correlating each to-be-remembered event with a distinct reward condition via Pavlovian trace conditioning, whereas the NOP results in random reward contingency. We found that hippocampal lesions did retard learning the matching rule, regardless of the reinforcement contingency assignment. However, when delay intervals were added to the task memory performance of subjects with hippocampal lesions was dramatically impaired--if subjects were not trained with the DOP. When subjects were trained with the DOP, the hippocampal lesion had a marginal effect on delayed memory performance. These findings demonstrate two important points regarding lesions of the hippocampus: (1) hippocampal lesions have a minimal effect on the on the ability of rats to use reward information to solve a delayed discrimination task; (2) rats with hippocampal lesions have the ability to learn about reward information using Pavlovian trace conditioning procedures.
