The phenomenology of minority–majority status: Effects on innovation in argument generation

In three experiments, we manipulated participants' perceived numerical status and compared the originality and creativity of arguments generated by members of numerical minorities and majorities. Independent judges, blind to experimental conditions, rated participants' written arguments. In Studies 1 and 2, we found that participants assigned to a numerical minority generated more original arguments when advocating their own position than did numerical majorities. In Study 3, an equal‐factions control group was included in the design, and all participants were instructed to argue for a counter‐attitudinal position. Those in the numerical minority generated more creative arguments than those in both the majority and equal‐factions conditions, but not stronger arguments. We propose cognitive and social processes that may underlie our obtained effects and discuss implications for minority influence research. Copyright © 2008 John Wiley & Sons, Ltd.     

Social perceptions of individuals missing upper front teeth

Although it is assumed that there are negative social consequences for individuals missing visible front teeth, no study of the way in which edentulous individuals were perceived in a social context and the potential social repercussions could be located. This initial study concerned college students' perceptions of individuals missing visible upper front teeth. 200 volunteers, 19 to 50 years of age (M = 20.6, SD = 4.4), rated five photographs depicting tooth presence or absence, from a full dentition to missing as many as four upper front teeth, on social traits including attractiveness, health status, educational attainment, satisfaction with life, active social life, aggressiveness, intelligence, trustworthiness, amount of caring, friendship, dating, and likelihood to live as a neighbor. Analysis suggested a person missing visible teeth was more negatively perceived on all social traits than a person with full dentition. Results were strongest when students were proposed to be linked to the edentulous individual in a personal way, i.e., dating or living as neighbor. Men and women agreed on perceptions of social traits and dentition condition. These results suggest the presence of strong Western cultural values, whereby those who are missing teeth may experience significant barriers to personal and social success.     

Expressed emotion and familial interaction: a study with agoraphobic and obsessive-compulsive patients and their relatives

Patients with panic disorder with agoraphobia (n = 40) or obsessive- compulsive disorder (n = 61) participated in a 10-min problem-solving interaction with their primary relative. Relatives were categorized as hostile or nonhostile toward the patient on the basis of a measure of expressed emotion (EE). Observed interactions between patients and their hostile relatives, relative to those of dyads with a nonhostile relative, were marked by higher rates of relatives' criticism and of patients' negativity but not by higher rates of negative reciprocity. Analyses of sequences indicated that the dyads with a hostile relative had a higher rate of sequences in which the relative was first critical and the patient then negative than was the case for dyads with nonhostile relatives. Moreover, hostile relatives were more frequently critical than nonhostile relatives whether patients' preceding behavior was positive, negative, or neutral. The findings are consistent with the stress-vulnerability model of the effect of EE on mental health, in that patients living with a high EE relative appear to be exposed to higher levels of interpersonal stress.     

Predictors of online information seeking by international students when disaster strikes their countries.

This study explores factors influencing international students' likelihood of using the Internet to seek disaster-related information should a disaster affect their countries. A cross-sectional survey was conducted in two universities in America between August 1 and September 30, 2005. Two hundred twenty-nine (n = 229) students completed the self-administered questionnaires. ANOVA analyses found that respondents' Internet self-efficacy had no significant impact on their intentions to seek disaster-related information on the Internet. However, respondents' Internet dependency and attitude toward seeking information online were found to have a significant effect on such intentions.     

Mindfulness Meditation for Symptom Reduction in Fibromyalgia: Psychophysiological Correlates

Objectives Fibromyalgia, a chronic pain syndrome, is often accompanied by psychological distress and increased basal sympathetic tone. In a previous report it was shown that mindfulness-based stress-reduction (MBSR) reduced depressive symptoms in patients with fibromyalgia with gains maintained at two months follow-up (Sephton et al., Arthr Rheum 57:77–85, 2007). This second study explores the effects of MBSR on basal sympathetic (SNS) activation among women with fibromyalgia. Methods Participants (n = 24) responded to a television news appearance, newspaper, and radio advertisements. Effects on anxiety, depressive symptoms, and SNS activation measures were tested before and after MBSR using a within-subjects design. Results The MBSR treatment significantly reduced basal electrodermal (skin conductance level; SCL) activity (t = 3.298, p = .005) and SCL activity during meditation (t = 4.389, p = .001), consistent with reduced SNS activation. Conclusions In this small sample, basal SNS activity was reduced following MBSR treatment. Future studies should assess how MBSR may help reduce negative psychological symptoms and attenuate SNS activation in fibromyalgia. Further clarification of psychological and physiological responses associated with fibromyalgia may lead to more beneficial treatment.     

The Mysterious Silence of Mother Earth in Laudato Si'

Laudato si' attempts simultaneously to disrupt prevailing global environmental discourse and to reorient central concepts in Catholic moral tradition by requalifying the meaning of dominion and by ecologically expanding human dignity. The image of Earth crying out to humans from within a kinship relation plays a central role in both arguments. However, the political consequences of those shifts remain vague because the “voice” of Earth remains silent in crucial loci of the encyclical's argument.     

The anencephalic as organ donor: Whose baby is it anyway?

Should an anencephalic newborn, lacking cerebral hemispheres but possessing a functional brain stem, be eligible for organ donation? The dialectical method is used here to envision how a protagonist and an antagonist might debate the ethics of the issue.     

CHILDREN'S THINKING IN BOTSWANA: PIAGET TASKS EXAMINED*

This Piaget replication study was done in Botswana. Six tasks were completed by 554 primary school children from urban, rural, and traditional village environments. Conservation of number, length, mass and weight, seriation and classification exercises were carried out using materials commonly found in the culture. Previous studies by other investigators have compared schooled and unschooled subjects in other African countries, but often unschooled subjects were from rural areas, so the environmental effects could not be isolated. In this study comparisons were made between students in the three environments, between age groups, and between male and female subjects. Urban children completed tasks at an earlier age than those from other environments. In general, the results are similar to findings from other African countries.     

Motivation in concurrent variable-interval schedules with food and water reinforcers

The lever pressing of four food- and water-deprived rats was reinforced on concurrent variable-interval schedules. Food reinforced one response, and water reinforced the other. Response rates in baseline were higher in the food component than in the water component. After response patterns and body weights had stabilized, the animals were given access to either food only, water only, both food and water, or neither food nor water (baseline) before daily sessions. Giving food before a session decreased per cent time in the food component, decreased overall response rates for food, and increased overall response rates for water. Giving water before a session increased per cent time in the food component, increased overall response rates for food, and decreased overall response rates for water. Giving both food and water before a session resulted in a combination of prefeeding and prewatering effects. More food and more water were consumed when both were available than when only one was available before a session.
