Longitudinal study of quality of life in acquired brain injury: A self- and proxy-report evaluation

Background/ObjectiveAfter an acquired brain injury (ABI), the person remains with several impairments and disabilities that cause a decrease in his/her quality of life (QoL), which could change over time. The objective of the study was to analyse the evolution patterns of QoL in a sample of persons with ABI for one-year as well as the differences in proxy- and self-report versions of a QoL instrument. Method: The sample comprised 402 persons with ABI with ages ranging between 18 and 91 years, whom 36.20% had had the accident recently (i.e., three years or less). Patients, professionals and relatives responded at three evaluation points to the CAVIDACE scale, an ABI-specific QoL tool. Results: ANOVAs showed an improvement in QoL in the two follow-ups; the improvement was especially significant in the period between baseline and six months. The respondent factor did not interact with the evaluation time, but significant differences were found between respondents, with scores of patients higher than that for proxies. Finally, the QoL’s evolution interacts with the time elapsed since injury, showing significant improvements in the most recent group (i.e., three years or less). Conclusions: QoL must be considered from the earliest moments after ABI to obtain more significant improvements.

Loving-kindness meditation: a field study

Surveys were conducted at two metta meditation retreats in order to examine the psychological effects of metta meditation. Participants were invited to complete the survey at the beginning of the retreat, at the end of the retreat, and two weeks after the end of the retreat. Participants completed the same scales at each time phase, which included measures of happiness, compassionate love, revenge and avoidance motivation, gratitude, and a depression, anxiety and stress scale. Significant increases were found in happiness and compassionate love, reductions in avoidance and revenge, and reductions on the depression, anxiety and stress subscales.     

Envy and us

Within emotion theory, envy is generally portrayed as an antisocial emotion because the relation between the envier and the rival is thought to be purely antagonistic. This paper resists this view by arguing that envy presupposes a sense of us. First, we claim that hostile envy is triggered by the envier's sense of impotence combined with her perception that an equality principle has been violated. Second, we introduce the notion of “hetero‐induced self‐conscious emotions” by focusing on the paradigmatic cases of being ashamed or proud of somebody else. We describe envy as a hetero‐induced self‐conscious emotion by arguing (a) that the impotence felt by the subject grounds the emotion's self‐reflexivity and (b) that the rival impacts the subject's self‐assessment because the rival is framed by the subject as an in‐group member. Finally, we elaborate on the asset at stake in envy. We contend that this is esteem recognition: The envier covets the esteem that her reference group accords to the rival. Because, in envy, the subject conceives of herself as member of a group to which the other is also understood to belong, we conclude that envy is a social emotion insofar as it presupposes a sense of us.     

Successive negative contrast after partial reinforcement in the consummatory behavior of rats

Rats given access to a 32% sucrose solution later reject a 4% solution significantly more than controls that have only received the 4% solution. In Experiment 1, this consummatory successive negative contrast (cSNC) effect was attenuated by previous exposure to 50% partial reinforcement. Furthermore, recovery from cSNC was also facilitated by partial reinforcement. In Experiment 2, the attenuating effects of partial reinforcement on cSNC were eliminated by administration of the benzodiazepine anxiolytic chlordiazepoxide (5 mg/kg) before nonreinforced trials. In Experiment 3, the attenuating effect of partial reinforcement was greater after a shift from 32 to 6% solution, than after a shift from 32 to 2% solution. The parallels between the effects of partial reinforcement on consummatory and instrumental behavior are discussed.     

AIDS and condom-related knowledge,beliefs, and behaviors in Mexican migrant laborers

A survey of 87 Mexican migrants (55 males and 32 females) who have lived and worked in the US since 1982 assessed AIDS and condom-related knowledge, beliefs, and sexual practices. Although respondents were highly knowledgeable about major modes of HIV transmission, one-third to one-half believed that HIV could be contracted from mosquito bites, public bathrooms, kissing, and the HIV test. Only 15% knew someone with AIDS. Ever-use of condoms was reported by 70.9% of men and 41.9% of women. Of the 68 subjects who had been sexually active in the year preceding the survey, 20 reported two or more partners. Among sexually active respondents, 16.2% always used condoms with their primary partner, while 43.0% used condoms consistently with occasional partners. 48.9% of men and 57.1% of women never used condoms with their primary partner; with casual partners, these rates were 30.8% and 44.4%, respectively. Worry about contracting AIDS, self-rated on a scale from 1 (very often) to 4 (never), averaged 2.84, with higher worry scores among those 18-31 years of age and with multiple partners. Respondents did not anticipate negative consequences of condom use (e.g., reduced sexual pleasure), but females expressed concern that carrying condoms would cause them to be viewed as promiscuous.     

The Importance of Social Context in Cross-Cultural Comparisons: First Graders in Colombia and the United States

The authors explored the cultural constructs of individualism and collectivism by investigating the prosocial behavior of 1st graders (N = 202; 110 girls, 92 boys) in countries typically classified as collectivist (Colombia, South America) and individualist (United States). Contrary to expectations. U.S. children shared more than Colombian children did. However, U.S. children were more likely to take candy from another child without permission (demonstrating individualism). Results indicated that in both countries sharing was greater with friends than with other fellow classmates, and children frequently reported friendship as the reason they shared. Findings support the importance of the social context, such as the relationship between participants, in cross-cultural research and suggest that simple dichotomies of culture often overlook complex associations between culture and behavioral differences.     

The effect of preview eccentricity in a lexical decision task

We report lexical decision experiments in which eye movements and lexical decision time were analysed. The results show that nonwords produced more fixation than words, and that the time to make a lexical decision was also greater for nonwords. Further, a preview of the stimulus was presented on some occasions either at fixation or peripherally. When the presentation was peripheral the number of refixations and lexical decision times were reduced. Parafoveal previews of words also reduced word length effects on refixations and lexical decision time. These effects decreased (for nonwords) when the case of the letters was changed in the preview. These results are compatible with the idea that the peripheral preview benefit derives from word visual structure in addition to information about word length, word envelope, and single letter identities.

Tuning in emotionally: Associations of cultural exposure with distal and proximal emotional fit in acculturating youth

The more immigrant minorities are exposed to the majority culture, the more their emotional pattern fits that of majority culture members—a phenomenon termed emotional acculturation. To assess emotional fit, earlier studies compared minorities’ emotional experience with that of separate samples of “distant” majority members in their country of residence. We added “proximal” fit with the emotional experience of majority members in their social environment. Drawing on large random samples of immigrant minority and majority youth in Belgian high schools (N = 2,543), our study aimed (i) to test majority culture exposure and contact as predictors of emotional fit and (ii) to distinguish emotional fit with distal and proximal variants of majority culture. Minorities’ majority culture exposure predicted both distal and proximal emotional fit. In addition, contact with majority peers better predicted proximal fit. Our findings suggest that emotional acculturation is socially grounded in interactions with proximal majority members.
