Terrorist threat,dehumanization, and right‐wing authoritarianism as predictors of discrimination

This study analyzed the relationship between terrorist threat and discrimination, operationalized by support for retributive justice against Islamic groups suspect of terrorist crimes. Two experimental studies were performed. Study 1 (N = 215) showed that the terrorist threat against the ingroup raises the support for the retributive procedures through the dehumanization of the outgroup. Study 2 (N = 304) analyzed how the mediating role of dehumanization in the relationship between terrorist threat and support for retributive justice is moderated by right‐wing authoritarianism (RWA). In addition, the study aimed to verify if the dehumanization of outgroup and RWA could explain the relationship between terrorist threat and discrimination of Muslim immigrants. The results indicated that adherence to RWA favors dehumanization of the outgroup and, consecutively, the discrimination, operationalized as support for the use of retributive justice. The adherence to RWA has been identified as the mechanism that explains the discrimination against Muslim immigrants.     

Problematic Facebook Use in Adolescents: Associations with Parental Attachment and Alienation to Peers

Facebook is, nowadays, the most used social networking site worldwide and adolescents are increasingly engaging in this form of communication. Despite increasing attention of researchers to computer-mediated communication, there are few studies using an interpersonal and family relationships perspective on how adolescents relate to the Internet, and particularly to Facebook use. The aim of the present study was to test whether peer alienation mediates the link between parental attachment and problematic Facebook use. To this purpose we used a sample of 761 adolescents (53.7% boys, mean age?=?15.8), from the North region of Portugal. We also tested if the mediational model was invariant for boys and girls. The results showed that peer alienation plays a mediating role in the relationship between parental attachment and problematic Facebook use. The mediational models were, however, not invariant for boys and girls. Considering parental attachment, quality of emotional bond directly predicted problematic Facebook use only for boys. These results provide relevant clues for understanding predictors of problematic Facebook use in adolescents and also enlighten psychological intervention, particularly in parental education and school intervention programs.     

Do Critical Thinkers Drink Too Much Alcohol,Forget to Do Class Assignments,or Cheat on Exams? Using a Critical Thinking Measure to Predict College Students’ Real-World Outcomes

Critical thinking is a higher-order way of reasoning composed of the skill and will to use cognitive abilities and knowledge on a daily basis. It is identified as essential by higher education institutions, corporations, and society in general. To analyze whether college students are critical thinkers in their daily lives, the Halpern Critical Thinking Assessment (HCTA; Halpern in Halpern Critical Thinking Assessment (Measurement instrument), Schuhfried, Mödling, 2012) and the real-world outcomes inventory (RWO; Butler in Appl Cogn Psychol 26(5):721–729, 2012) were administered to 238 students. We performed a cluster analysis (K-means-constrained clustering method), and ANOVAs for each cluster solution tested to identify the most suitable clustering solution, taking the RWO inventory dimensions as dependent variables and cluster membership as an independent variable. Four separate clusters emerged, each representing a different profile related to students’ everyday negative outcomes resulting from a lack of critical thinking. We performed multinomial logistic regression to examine which dimensions of the HCTA test, as well as gender, age, and disciplinary area, predicted the four singular groups of students that emerged: “Mature,” “Risk-taking,” “Lost in translation,” and “Reflective.” Results indicate that: (1) age is a relevant predictor of slackness, rashness, and health neglect, all characteristics of “Mature” students; (2) students who are particularly skilled in hypothesis testing tend to be “Risk-taking,” while it is less likely that students who are specifically competent in argument analysis will be in this group; (3) gender is relevant to predict “Lost in translation” students, while argument analysis is negatively related to the chances of being in this group. Our study supports the relevance of critical thinking in daily decisions and everyday outcomes.     

Age differences in personality traits across cultures: self‐report and observer perspectives

Using self‐report measures, longitudinal studies in the US and cross‐sectional studies from many cultures suggest that the broad factors of Neuroticism, Extraversion, and Openness to Experience decline from adolescence to adulthood, whereas Agreeableness and Conscientiousness increase. Data are inconsistent on the rate of change during adulthood, and on the generalizability of self‐report findings to informant ratings. We analysed cross‐sectional data from self‐reports and informant ratings on the Revised NEO Personality Inventory in Czech (N = 705) and Russian (N = 800) samples. Some curvilinear effects were found, chiefly in the Czech sample; informant data generally replicated self‐reports, although the effects were weaker. Although many of the details are not yet clear, there appear to be pan‐cultural trends in personality development that are consistent with the hypothesis of intrinsic maturation.

Basolateral amygdala inactivation impairs learned (but not innate) fear response in rats

Numerous studies have suggested that the amygdala is involved in the formation of aversive memories, but the possibility that this structure is merely related to any kind of fear sensation or response could not be ruled out in previous studies. The present study investigated the effects of bilateral inactivation of the amygdaloid complex in rats tested in the plus-maze discriminative avoidance task. This task concomitantly evaluates aversive memory (by discrimination of the two enclosed arms) and innate fear (by open-arm exploration). Wistar rats (3-5 months-old) were implanted with bilateral guide cannulae into basolateral amygdala. After surgery, all subjects were given 1 week to recover before behavioral experiments. Afterwards, in experiment 1, 15 min prior to training, 0.5 μl of saline or muscimol (1 mg/ml) was infused in each side via microinjection needles. In experiment 2 the animals received injections immediately after the training session and in experiment 3 rats were injected prior to testing session (24 h after training). The main results showed that (1) pre-training muscimol prevented memory retention (evaluated by aversive arm exploration in the test session), but did not alter innate fear (evaluated by percent time in open arms); (2) post-training muscimol impaired consolidation, inducing increased percent in aversive arm exploration in the test session and (3) pre-testing muscimol did not affect retrieval (evaluated by aversive enclosed arm exploration in the test session). The results suggest that amygdala inactivation specifically modulated the learning of the aversive task, excluding a possible secondary effect of amygdala inactivation on general fear responses. Additionally, our data corroborate the hypothesis that basolateral amygdala is not the specific site of storage of aversive memories, since retention of the previously learned task was not affected by pre-testing inactivation.     

Brazelton Neonatal Behavioral Assessment Scale: A psychometric study in a Portuguese sample

BackgroundThe Neonatal Behavioral Assessment Scale (NBAS, Brazelton &; Nugent, 1995) is an instrument conceived to observe the neonatal neurobehavior. Data analysis is usually performed by organizing items into groups. The most widely used data reduction for the NBAS was developed by Lester, Als, and Brazelton (1982).ObjectiveExamine the psychometric properties of the NBAS items in a sample of 213 Portuguese infants.MethodThe NBAS was performed in the first week of infant life (3 days ± 2) and in the seventh week of life (52 days ± 5).ResultsPrincipal component analyses yielded a solution of four components explaining 55.13% of total variance. Construct validity was supported by better neurobehavioral performance of 7-week-old infants compared with 1-week-old infants.ConclusionChanges in the NBAS structure for the Portuguese sample are suggested compared to Lester factors in order to reach better internal consistency of the scale.     

Grammatical and nongrammatical contributions to closed-class word selection

Closed-class word selection was investigated by focusing on determiner production. Native speakers from three different languages named pictures of objects using determiner plus noun phrases (e.g., in French "la table" [the-sub(feminineA) table], while ignoring distractor determiners printed on the pictures (e.g., "le" [the-sub(masculine)]. The target and distractor expressed either shared or different grammatical and nongrammatical features (gender, number, and definiteness). A gender-facilitation effect was observed and attributed to noun processing. Crucially, across five experiments, distractors that shared a feature with the target determiner never resulted in longer naming latencies than distractors that were more different. These results indicate that activating related candidates is not detrimental for determiner retrieval, suggesting a noncompetitive mechanism of closed-class word selection.     

Does bilingualism hamper lexical access in speech production?

In the present study, we tested the hypothesis that bilingualism may cause a linguistic disadvantage in lexical access even for bilinguals' first and dominant language. To this purpose, we conducted a picture naming experiment comparing the performance of monolinguals and highly-proficient, L1-dominant bilinguals. The results revealed that monolinguals name pictures faster than bilinguals, both when bilinguals perform picture naming in their first and dominant language and when they do so in their weaker second language. This is the first time it has been demonstrated that bilinguals show a naming disadvantage in their L1 in comparison to monolingual speakers.     

Personality trait similarity between spouses in four cultures

We examined patterns of trait similarity (assortative mating) in married couples in four cultures, using both self-reports and spouse ratings on versions of the Revised NEO Personality Inventory. There was evidence of a subtle but pervasive perceived contrast bias in the spouse-rating data. However, there was strong agreement across methods of assessment and moderate agreement across cultures in the pattern of results. Most assortment effects were small, but correlations exceeding .40 were seen for a subset of traits, chiefly from the Openness and Agreeableness domains. Except in Russia, where more positive assortment was seen for younger couples, comparisons of younger and older cohorts showed little systematic difference. This suggested that mate selection, rather than convergence over time, accounted for similarity. Future research on personality similarity in dyads can utilize different designs but should assess personality at both domain and the facet levels.
