Case study: Research with brain-dead children

The esophageal obturator airway (EOA) is a device used throughout the United States to facilitate artificial respiration of critically ill patients who are not hospitalized. Its use is restricted to persons who are over 15 years old because obturators for children are not available. A protocol submitted to an institutional review board (IRB) intended to develop EOAs suitable for use in children. The investigators proposed to perform preliminary testing of these devices on children who had sustained irreversible loss of brain function (“brain death”). In its review of this protocol, the IRB had to confront several vexing questions.     

Black College Women's Career Values: A Preliminary Investigation

We identified nine values that guided the career decisions of a sample of Black college women, then explored whether these values were predicted by racial and feminist identify stage sentiments Findings from this study suggest the need for further research on the career development of women of color.     

Mentors' perceptions of negative mentoring experiences: scale development and nomological validation

Three studies were conducted to develop a psychometrically sound, multidimensional measure of mentors' perceptions of negative experiences with their protégés. In Study 1, items were developed, and content-related validity was established. In Study 2, CFA was used to establish the dimensionality of the new measure. Construct-related (convergent and discriminant) and criterion-related validity evidence were also obtained by using data from matched mentor-protégé dyads. Study 3 replicated the factor structure of the instrument and provided additional validity evidence by using a sample of female academic mentors. The findings are discussed in terms of broadening the scope of mentoring research to consider the mentor's perspective of relationship problems and dyadic processes in mentoring relationships.     

Why are conservatives happier than liberals?

In this research, we drew on system-justification theory and the notion that conservative ideology serves a palliative function to explain why conservatives are happier than liberals. Specifically, in three studies using nationally representative data from the United States and nine additional countries, we found that right-wing (vs. left-wing) orientation is indeed associated with greater subjective well-being and that the relation between political orientation and subjective well-being is mediated by the rationalization of inequality. In our third study, we found that increasing economic inequality (as measured by the Gini index) from 1974 to 2004 has exacerbated the happiness gap between liberals and conservatives, apparently because conservatives (more than liberals) possess an ideological buffer against the negative hedonic effects of economic inequality.     

Affective ratings of sound stimuli

This article present the Spanish assessments of the 111 sounds included in the International Affective Digitized Sounds (IADS; Bradley &; Lang, 1999b). The sounds were evaluated by 159 participants in the dimensions of valence, arousal, and dominance, using a computer version of the Self-Assessment Manikin (Bradley &; Lang, 1994). Results are compared with those obtained in the American version of the IADS, as well as in the Spanish adaptations of the International Affective Picture System (P. J. Lang, Bradley, &; Cuthbert, 1999; Moltó et al., 1999) and the Affective Norms for English Words (Bradley &; Lang, 1999a; Redondo, Fraga, Padrón, &; Comesaña, 2007).     

Predictive Factors of Ethnic Prejudice Toward Immigrants in a Representative Subsample of Spanish Young People1

This research aimed to study those factors that predict different types of ethnic prejudice in a representative subsample of Spanish young people. The instrument we used was Pettigrew & Meertens' (1995 ) blatant/subtle prejudice scale. Results show that although there is a similar underlying pattern in both types of ethnic prejudice, subtle prejudice is based more on cultural differences, whereas blatant prejudice also stresses the racial, economic, and labor effects of immigration. Moreover, blatant prejudice is also influenced by the formal level of education and political position. The results are interpreted within the Spanish context; and the implications for identity formation and maintenance, and practical programs directed toward ethnic prejudice awareness are discussed.     

Are needs to manage uncertainty and threat associated with political conservatism or ideological extremity?

Three studies are conducted to assess the uncertainty- threat model of political conservatism, which posits that psychological needs to manage uncertainty and threat are associated with political orientation. Results from structural equation models provide consistent support for the hypothesis that uncertainty avoidance (e.g., need for order, intolerance of ambiguity, and lack of openness to experience) and threat management (e.g., death anxiety, system threat, and perceptions of a dangerous world) each contributes independently to conservatism (vs. liberalism). No support is obtained for alternative models, which predict that uncertainty and threat management are associated with ideological extremism or extreme forms of conservatism only. Study 3 also reveals that resistance to change fully mediates the association between uncertainty avoidance and conservatism, whereas opposition to equality partially mediates the association between threat and conservatism. Implications for understanding the epistemic and existential bases of political orientation are discussed.     

Recognition memory for pictorial stimuli: biasing effects of stimulus emotionality

The possibility that stimulus emotionality might influence recognition bias in a long-term memory task was studied with respect to both the valence and arousal dimensions of emotion. For this purpose, we used 108 International Affective Picture System pictures that were representative of all regions of this two-dimensional space. Signal detection theory analysis was applied using A'and B' D as discrimination and bias measures, respectively. In general, the results showed that greater discrimination was accompanied by a response bias that was more conservative for pleasant and for unarousing pictures than for unpleasant and for arousing ones. These results provide new evidence in connection with the emotion-induced recognition bias in long-term memory performance.     

Negative Affectivity,Political Contention,and Turnout: A Genopolitics Field Experiment

Recent genopolitics and political psychology research suggests individuals' biological differences influence political participation. The interaction between individual differences and environments has received less attention, not least because of the confound of self‐selection into environments. To test the interaction between innate predispositions and an exogenous environmental influence, we conducted a field experiment during the 2010 California midterm elections. We randomly assigned subjects to receive a postcard mobilization treatment designed to induce an emotional response to the degree of political contention in the election. We tested the possibility that subjects who are genetically predisposed toward negative affectivity will be less likely to vote after treatment exposure. To our knowledge, this is the first field experiment in political science to measure genetic moderation of a treatment, and it suggests experimental approaches can benefit from the inclusion of genetically and other biologically informative covariates.
