Brief report: Validation of a reinforcer survey for use with geriatric patients

This paper describes a Geriatric Reinforcer Survey (GRS) which expands upon a previous Reinforcement Survey Schedule (RSS) developed by Cautela and Kastenbaum (1967). The GRS, an instrument designed to quickly assess reinforcer preference in geriatric populations, has two formats, one for individuals over 65 years of age who are still able to comprehend and write, and one designed to be filled out by relatives and staff familiar with an individual over 65 years of age who can no longer comprehend or write well. Reinforcer preference was determined by giving the GRS to a total of 107 geriatric persons in both home and institutional settings. Test-retest reliability was assessed on a subsample of 71 individuals over a 10-14-day period and was found to be r_s = 0.608, p <0.01 using the Spearman Rank-Order Correlation Coefficient. This indicated that the GRS had reasonable test-retest reliability. The validity of having a relative or familiar staff person fill out the GRS for a specific individual was also tested. Results of 43 administrations of the GRS to relatives of a geriatric person, using the Spearman Rank-Order Correlation Coefficient, showed a correlation of r_s = 0.488, p <0.01 when the responses of that person were compared to those of the individual. Results of 17 administrations of the GRS to staff familiar with a particular patient were r_s = 0.436, p < 0.05 when compared to responses made by the individual. This indicates that the GRS might be useful in structuring interventions for individuals who are incapacitated, and groups of geriatric persons. The GRS also has the potential to be a valuable research tool.     

Immobilization Stress Elevates GTP Cyclohydrolase I mRNA Levels in Rat Adrenals Predominantly by Hormonally Mediated Mechanisms

GTP cyclohydrolase I (GTPCH) is the rate-limiting enzyme in the biosynthesis of tetrahydrobiopterin, the cofactor for catecholamine, indolamine and nitric oxide biosynthesis. In this study we examined the effect of immobilization stress on GTPCH mRNA levels and the mechanism(s) of stress-induced changes in adrenomedullary GTPCH mRNA levels. We used reverse-polymerase chain reaction to isolate and clone a cDNA corresponding to nucleotides 269 to 570 of rat GTPCH. Northern blot analysis with a cRNA probe revealed two species of GTPCH mRNA (about 3.6 and 1.2 kb) in rat adrenal medulla and cortex, and in PC12 cells. The levels of both forms of GTPCH mRNA were significantly increased 3-5 fold in adrenal medulla by a single 2 hour immobilization and by repeated immobilizations (2 hours a day for 2 days). Hypophysectomy had little effect on their basal levels but prevented the stress elicited rise in both GTPCH mRNAs. In contrast, unilateral transection of the splanchnic nerve did not affect induction of the 3.6 kb GTPCH mRNA by stress. Combined denervation with hypophysectomy completely blocked the induction of both GTPCH mRNA species by immobilization stress. Thus, stress elicits elevation of both forms of GTPCH mRNA by a mechanism requiring an intact pituitary-adrenocortical axis.     

Retrospective reports of dream characteristics and preferences for organic vs. junk foods

The authors investigated correlations between retrospective dream characteristics, food preferences, and eating attitudes. Graduate students (7 men, 42 women) at Santa Clara University were administered the MEGA food scale and the KJP Dream Inventory. High intake of organic food was positively correlated with reports of multiple dream factors. Conversely, high scores on preferences for fast food, potato chips, and carbohydrates were negatively correlated with several factors. Findings are discussed in terms of the hypothesis that certain foods may influence dreaming.     

Psychological essentialism and the differential attribution of uniquely human emotions to ingroups and outgroups

According to the psychological essentialism perspective, people tend to explain differences between groups by attributing them different essences. Given a pervasive ethnocentrism, this tendency implies that the human essence will be restricted to the ingroup whereas outgroups will receive a lesser degree of humanity. Therefore, it is argued that people attribute more uniquely human characteristics to the ingroup than to the outgroup. The present article focuses on secondary emotions that constitute such characteristics. Study 1 showed that members of high‐ and low‐status groups attribute more positive secondary emotions to the ingroup than to the outgroup. Study 2 verified that the differential attribution extended also to negative secondary emotions. No exemplars of emotions were provided in Study 3. Instead, participants had to estimate the means of two distributions of numbers that supposedly represented characteristics of the ingroup and of the outgroup. The results of this third experiment illustrated the reluctance to attribute secondary emotions to the outgroup. The findings are discussed from the perspective of psychological essentialism.

Anger and social appraisal: a "spicy" sex difference?

The central objective of this study was to investigate the role of social appraisal in sex differences in anger expression. Anger expression was inferred from the amount of hot sauce given to the person who induced anger. Participants were randomly assigned to a social condition, in which they expected to meet this person, or to a nonsocial condition, in which they had no such expectation. Men and women differed in their anger expressions, despite the fact that they did not differ in anger experience. Women expressed anger to a lesser extent than men, but only in the social condition. Social appraisal partly mediated the relation between sex and anger expression. The role of social appraisal in emotion and appraisal theory is discussed.     

Flank transparency: transparent filters seen in dynamic two-color displays

Flank transparency is the perception of a colored transparent filter evoked by apparent-motion displays containing as few as two colors. Displays of flank transparency contain a random array of line segments placed on a uniform background. Small flanks are added to the line segments if the segments fall in the interior of a moving virtual shape, such as a virtual disk. This leads to the perception of a colored transparent disk with well-defined boundaries moving over the array of lines. Current qualitative and quantitative models of luminance and color conditions for perceptual transparency do not account for flank transparency as they require displays containing at least three different colors.     

Inclusiveness of identification among farmers in The Netherlands and Galicia (Spain)

In this paper we discuss inclusiveness of identification among farmers in Galicia (Spain) and The Netherlands. Identification with three nested categories—farmers in the local community, farmers in the country, and farmers in Europe was assessed among 167 Dutch and 248 Galician farmers at three points in time: winter of 1993/94, winter 1995 and fall 1995. Our findings suggest that inclusiveness reduces the level of identification. However, the observed patterns of identification were more complex than inclusiveness per se can account for. Borrowing from the common ingroup‐identity model, functional and socialization models of identity formation, and a model of politicized collective identity we formulated hypotheses about patterns of identification that were to be expected. On the whole our findings supported our theoretical reasoning. Galician farmers appear to identify much less with farmers in their country and Europe than Dutch farmers do. Inclusiveness of identification appears to be linked to experience with national and supranational political institutions. More political knowledge and involvement appear to generate more inclusive patterns of identification. Among Galician farmers evaluation of the agricultural policy of the European Union is negatively related to identification with farmers in Europe, among Dutch farmers the two are positively related. Finally, more inclusive identities seem to be more politicized. Copyright © 2004 John Wiley & Sons, Ltd.
