Preferences for Life-Prolonging Medical Treatments and Deference to the Will of God

We defined and measured a dimension of religiosity frequently invoked in end-of-life (EOL) research—deference to God’s Will (GW)—and examined its relationship to preferences for life-prolonging treatments. In a 35-min telephone interview, 304 older men and women (60 +) were administered the 5-item GW scale, sociodemographic questions, three attitude items regarding length of life, and measures of two health indices, depression, and life-prolonging treatment preferences. The GW scale demonstrated internal consistency (Cronbach’s alpha = .94) and predictive and discriminant validity. Higher scores indicative of greater deference to GW were associated with stronger life-prolonging treatment preferences in poor-prognosis scenarios. Implications for the role of religiosity in medical decision-making are discussed.     

Met expectations: The effects of expected and delivered inducements on employee satisfaction

Interpretation of existing theory and research on met expectations is problematic due to ambiguous conceptualization of the met expectations hypothesis and limitations imposed by the measurement strategies typically employed in this domain (i.e. difference scores and direct retrospective measures). In this longitudinal study, we sought to overcome these problems by using an alternative methodology to conduct a more comprehensive test of the met expectations hypothesis based on Warr's (1987) Vitamin Model and on research in related fields (e.g. person–environment fit). Polynomial regression and response surface analyses were used to examine how employee satisfaction is related to unmet, met, and exceeded expectations concerning two distinct types of inducements analogous to vitamins A (skill development opportunities) and E (support, compensation). Respondents included 342 limited term employees. Consistent with previous research, our results indicated that unmet expectations of any sort were associated with decreased satisfaction. However, contrary to common interpretations of the extant literature, our results also indicated that met expectations were not always associated with high levels of satisfaction and that exceeded expectations were, in the case of skill development, negatively associated with satisfaction. These findings suggest a need to broaden existing met expectations theory and to refine common organizational practices.     

Televised sexual content and parental mediation: Influences on adolescent sexuality

Little research has been conducted to examine the influence of exposure to televised sexual content on adolescent sexuality or how parental intervention may reduce negative effects of viewing such content. This study uses self-report data from 1,012 adolescents to investigate the relations among exposure to sexually suggestive programming, parental mediation strategies, and three types of adolescent sexuality outcomes: participation in oral sex and sexual intercourse, future intentions to engage in these behaviors, and sex expectancies. As predicted, exposure to sexual content was associated with an increased likelihood of engaging in sexual behaviors, increased intentions to do so in the future, and more positive sex expectancies. Often, parental mediation strategies were a significant factor in moderating these potential media influences.     

Beyond cognition: predicting health risk behaviors from instrumental and affective beliefs.

OBJECTIVE: Two studies assessed the relative contribution of affective and instrumental beliefs to the prediction of 2 risk behaviors: driving above the speed limit and smoking. DESIGN: Both studies took the form of large-scale questionnaire surveys (Study 1, N=292; Study 2, N=500) measuring instrumental and affective beliefs and self-reported behavior. In both cases, behavior was also measured objectively. OUTCOME MEASURES: In Study 1, speeding behavior was measured via infrared camera along sections of road with 30 mph, 40 mph, and 60 mph speed limits. Self-reports of speeding in these same contexts represented a 2nd dependent variable. In Study 2, level of smoking was measured via a carbon monoxide monitor, and participants were asked to indicate the number of cigarettes they smoked in a week. RESULTS: In Study 1, positive and negative instrumental and affective beliefs were significant predictors of self-reported speed. The most powerful predictor was negative affective beliefs. Observed speed was predicted by negative affective beliefs only. In Study 2, the significant predictors of self-reported smoking and objective measures of smoking were positive and negative affective beliefs. CONCLUSION: The findings indicate the importance of affective beliefs across 2 health risk behaviors. Implications for social cognition models and interventions are discussed.     

Identity as a moderator of gender differences in the emotional closeness of emerging adults' same- and cross-sex friendships

Closeness is an integral aspect of friendships, and males and females differ in their closeness experiences within these relationships. However, identity development and friendship type (e.g., same-sex versus cross-sex friendships) may moderate these gender differences. In an attempt to clarify the relationships among gender, identity, and friendship closeness, the current study examined gender and identity associations with reported emotional closeness in emerging adults' same- and cross-sex friendships. Responses from 181 college undergraduates (89 males and 92 females) indicated similar levels of emotional closeness reported for same- and cross-sex friendships. Results also indicated overall identity commitment and friendship identity commitment associations with same-sex friendship closeness. Examination of closeness reports for cross-sex friends revealed a significant association with overall identity commitment for emerging adult males. A significant association was not indicated for emerging adult females. The associations between identity and emotional closeness in same-sex friendships and male cross-sex friendships support previous studies that report differences in the role of these relationships for emerging adult males and females. Findings are discussed in terms of understanding the gender and identity differences in emerging adults' reports of friendship closeness.     

"John thinks that Mary feels. . ." False belief in children across affective and physical domains

Children aged 5-8 years (N = 64) were given 3 first- and 3 second-order tasks testing their ability to represent false beliefs about physical facts, positive emotions, and negative emotions. The children were also asked to justify their responses to the test questions. Older children were more successful than younger children at both answering the test questions correctly and justifying their responses. On the first-order problems, performance was better on the physical fact task than on the emotions tasks; the reverse was true for the second-order problems. Children primarily used situational explanations to explain correct judgments on the physical problems, whereas mentalistic explanations were more common than situational explanations on 3 of the 4 emotions tasks. The results extend knowledge of false belief beyond the simple forms studied at the preschool level.     

Useful effect size interpretations for single case research

An obstacle to broader acceptability of effect sizes in single case research is their lack of intuitive and useful interpretations. Interpreting Cohen's d as "standard deviation units difference" and R2 as "percent of variance accounted for" do not resound with most visual analysts. In fact, the only comparative analysis widely supported in single case research (SCR) is "percent of nonoverlapping data." This article explores five alternative interpretations of Cohen's d and R2 effect sizes that may be more acceptable to the SCR field. They are: (a) Cohen's (Cohen, J. (1988). Statistical power analysis for the behavioral sciences (2nd ed.). Hillsdale, NJ: Lawrence Erlbaum) "Percent of Nonoverlapping Data" (CPND), (b) Parker et al.'s (Parker, R.I., Cryer, J., Byrns, G., 2006. Controlling trend in single case research. School Psychology Quarterly, 21, 418-440, Parker, R.I., Hagan-Burke, S., Vannest, K., in press. Percent of all non-overlapping data (PAND): An alternative to PND. Journal of Special Education) "Percent of All Nonoverlapping Data" (PAND), (c) Rosenthal et al. (Rosenthal, R., Rosnow, R., & Rubin, D. (2000). Contrasts and effect sizes in behavioral research: A correlational approach. Cambridge: Cambridge University Press.) "Binomial Effect Size Display" (BESD), (d) "Percentile Rank in Control Group" (PR), and (e) McGraw and Wong's (McGraw, K. O., & Wong, S. P. (1992). A common language effect-size statistic. Psychological Bulletin, 111, 361-365) "Common Language Effect Size" (CLES). Each of the five interpretation schemes are applied to a published data set and are evaluated according to (a) intuitive appeal, (b) relevance to visual analysis, (c) ease of calculation, and (d) technical adequacy. Three of the five appear to be improvements over prevailing practice.     

Morningness/eveningness, morning-to-afternoon cortisol ratio, and antisocial behavior problems during puberty

The relationship between morningness/eveningness (M/E) and morning-to-afternoon cortisol ratio, pubertal timing, and antisocial behavior was examined in 111 girls and boys ages 8 to 13 years. Cortisol levels showed a significant increase after awakening and declined thereafter (p<.05). Eveningness was related to a composite measure of antisocial behavior and rule-breaking and attention behavior problems and conduct disorder (CD) symptoms in boys and relational aggression in girls. In boys only, lower a.m. to p.m. cortisol ratio, indicating less circadian decrease in cortisol, was related to attention problems. Early pubertal timing was associated with boys' rule-breaking and attention behavior problems and CD symptoms and girls' relational aggression. The findings indicate that evening activity preference; extreme a.m. to p.m. cortisol ratios, in one case; and early pubertal timing were associated with antisocial behavior even in young adolescents, but the findings were stronger for boys than for girls.     

Effects of bilateral eye movements on gist based false recognition in the DRM paradigm

The effects of saccadic bilateral (horizontal) eye movements on gist based false recognition was investigated. Following exposure to lists of words related to a critical but non-studied word participants were asked to engage in 30s of bilateral vs. vertical vs. no eye movements. Subsequent testing of recognition memory revealed that those who undertook bilateral eye movement were more likely to correctly recognise previously presented words and less likely to falsely recognise critical non-studied associates. This result joins other research in demonstrating the conditions in which false memory effects can be attenuated.     

Pre-training to find a hidden platform in the Morris water maze can compensate for a deficit to find a cued platform in a rat model of Parkinson's disease

The bilateral intranigral infusion of 1 micromol 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) in adult male Wistar rats caused a specific and partial loss of substantia nigra pars compacta (SNc) dopamine neurons, a partial depletion of striatal dopamine, and a deficit to learn the intra-maze cued version of the Morris water maze. Pre-training the SNc rats in the spatial version of the water maze or simply maintaining the animals on the water maze platform reversed this deficit. This improvement was even observed when the order of the extra-maze cues presented to the rats during pre-training of the spatial version was changed during training of the intra-maze cued version. However, this deficit was not reversed either by maintaining the animals on the platform if the spatial cues were surrounded and covered with a curtain or by swimming sessions in the maze without the escape platform and the curtain. These findings suggest that none of the following elements alone, learned during the spatial task pre-training, could help SNc rats learn the intra-maze cued task: improvement of swimming skills or knowledge of the existence of the escape platform; distance between the platform and the border of the pool; location of a particular extra-maze cue; relations among extra-maze cues. However, the simultaneous presence of the escape platform and extra-maze cues (irrespective of their relational configuration) during the pre-training sessions proved to be necessary for this improving effect to occur.
