Symptoms of PTSD Among Adolescents and Young Adult Survivors Six Years after the 2010 Haiti Earthquake

This study investigates the long-term consequences for adolescents and young adults who experienced the January 12, 2010, earthquake that struck Haiti. It aims to evaluate the consequences of the earthquake in adolescents and young adults six years after the disaster. During May and June 2016, in Port-au-Prince, 723 adolescents and young adults (364 girls and young women) aged 14 to 24 were assessed by means the Impact of Event Scale–Revised (IES-R) in addition to social demographic characteristics. In our sample, 35.82% reported clinically significant symptoms of PTSD, with a higher prevalence for girls and young women. They also had consistently higher scores than boys and young men on every subscale. Participants with working parents had consistently higher scores across all the subscales than participants whose parents did not work. This study showed that, more than six years after the earthquake, more than one third of the participants assessed had severe PTSD symptoms. Our results may prove useful for setting up mental health programs and devising tools appropriate for the youth population in Haiti.     

Some Aspects of Polyadic Inductive Logic

We give a brief account of some de Finetti style representation theorems for probability functions satisfying Spectrum Exchangeability in Polyadic Inductive Logic, together with applications to Non-splitting, Language Invariance, extensions with Equality and Instantial Relevance.     

Is happiness having what you want, wanting what you have, or both?

Rabbi Hyman Schachtel (1954) proposed that "happiness is not having what you want, but wanting what you have" (p. 37). In two studies, we tested Schachtel's maxim by asking participants whether or not they had and the extent to which they wanted each of 52 material items. To quantify how much people wanted what they had, we identified what they had and the extent to which they wanted those things. To quantify how much people had what they wanted, we identified how much they wanted and whether or not they had each item. Both variables accounted for unique variance in happiness. Moreover, the extent to which people wanted what they had partially mediated effects of gratitude and maximization on happiness, and the extent to which they had what they wanted partially mediated the effect of maximization. Results indicate that happiness is both wanting what you have and having what you want.     

Interpersonal politics: the role of terror management and attachment processes in shaping political preferences

Research on terror management theory (TMT) indicates that reminders of death affect political attitudes, but political orientation only sometimes moderates these effects. We propose that secure relationships are associated with values of tolerance and compassion, thus orienting people toward liberalism; insecure attachments are associated with more rigid and absolutist values that orient people toward conservatism. Given that attachment relationships become especially active when security needs are heightened, we predicted that mortality salience would be an important factor in understanding the relationship between attachment processes and political orientation. Supporting these ideas, Study 1 showed that after a mortality-salience manipulation, securely attached participants increased their support for a liberal presidential candidate, and less securely attached participants increased their support for a conservative presidential candidate. In Study 2, a secure-relationship prime following a mortality-salience manipulation engendered a less violent approach to the problem of terrorism than did a neutral-relationship prime. We discuss the interaction of TMT processes and individual differences in attachment in shaping political preferences.     

Constant versus variable response signal delays in speed—accuracy trade-offs: Effects of advance preparation for processing time

In two experiments, we used response signals (RSs) to control processing time and trace out speed—accuracy trade-off (SAT) functions in a difficult perceptual discrimination task. Each experiment compared performance in blocks of trials with constant and, hence, temporally predictable RS lags against performance in blocks with variable, unpredictable RS lags. In both experiments, essentially equivalent SAT functions were observed with constant and variable RS lags. We conclude that there is little effect of advance preparation for a given processing time, suggesting that the discrimination mechanisms underlying SAT functions are driven solely by bottom-up information processing in perceptual discrimination tasks.
