Superstition predicts perception of illusory control

Superstitions are common, yet we have little understanding of the cognitive mechanisms that bring them about. This study used a laboratory‐based analogue for superstitious beliefs that involved people monitoring the relationship between undertaking an action (pressing a button) and an outcome occurring (a light illuminating). The task was arranged such that there was no objective contingency between pressing the button and the light illuminating – the light was just as likely to illuminate whether the button was pressed or not. Nevertheless, most people rated the causal relationship between the button press and the light illuminating to be moderately positive, demonstrating an illusion of causality. This study found that the magnitude of this illusion was predicted by people's level of endorsement of common superstitious beliefs (measured using a novel Superstitious Beliefs Questionnaire), but was not associated with mood variables or their self‐rated locus of control. This observation is consistent with a more general individual difference or bias to overweight conjunctive events over disjunctive events during causal reasoning in those with a propensity for superstitious beliefs.     

Low self‐esteem,entrapment, and reason for living: A moderated mediation model of suicidal ideation

Adolescent suicidal ideation has become a top public health concern. It is thus significant to explore both risk and protective factors of adolescent suicidal ideation. The present study tested a moderated mediation model of suicidal ideation in a sample of Chinese adolescents. Chinese adolescents of 1074 (54.2% females, aged between 11 and 18 years) completed questionnaires assessing self‐esteem, entrapment, reason for living, and suicidal ideation. We found that entrapment mediated the association between low self‐esteem and suicidal ideation. The association between entrapment and suicidal ideation was moderated by reason for living. Findings of this study may expand our understanding of the development of suicidal ideation, and facilitate future research exploring the interplay of risk and protective factors of suicidality. Clinical implications of these findings were also discussed.     

When Core Self-Evaluation Leads to Career Adaptability: Effects of Ethical Leadership and Implications for Citizenship Behavior

Drawing upon the career construction theory and the trait activation theory, the present study first aims to uncover the interactive effect of core self-evaluation (CSE) and ethical leadership on career adaptability. In addition, the authors examined how career adaptability mediates the interaction effect of CSE and ethical leadership on organizational citizenship behavior (OCB). Two-wave data from 156 employees were collected in a manufacturing company over a one-month interval. Results showed that ethical leadership moderated the relationship between CSE and career adaptability. Specifically, the positive relationship between CSE and career adaptability was stronger when ethical leadership was low. Moreover, career adaptability mediated the relationship between CSE and OCB, and ethical leadership moderated this indirect relationship. We discuss implications for career adaptation and organizational effectiveness.     

Dynamique des processus de développement de carrière en contexte contre-stéréotypique : modélisation de la réussite des femmes militaires aux formations professionnelles

Careers in the French Navy are determined by successive certifications allowed military to have more and more managerial responsibilities. Women are unequally represented in the hierarchy. Military identity is deeply associated with male characteristics (Sorin, 2003). Women encounter difficulties to be perceived as military in their own right (Héritier, 2011), but also to articulate their identity as women with their professional identity, de facto in opposition (Toulgoat, 2002). On the one hand women's family life is seen as incompatible with service life (Caraire & Léger, 2000), on the other hand, within the crews of warships, their skills are underestimated (Matthews, Ender, Laurence, & Rohall, 2009). The objective of this study is to model the effects of professional identifications and self-assessment of competences on the success of military women in professional certifications. We interviewed 154 students in training to become “experienced operators” (including 73 women) with an average of 3.32 years of duty (SD = 2.11) and 61 students in training to become “team leader” (including 20 women) with an average of 9.28 years of duty (SD = 3.30). The questionnaire measures self-efficacy (Bandura, 1977), performance expectations compared to their colleagues (Rosenthal, Crisp, & Suen, 2007), identification to the professional group (Laplante & Tougas, 2011) and identification to the organization (Tougas, Rinfret, Beaton, & de la Sablonniere, 2005). The final score at the end of the training is considered as an indicator of success. While women are as successful as men in the certification “operator”, they are less successful in the certification “team leader”. The structural equation model (path analysis) (χ²(15, n = 215) = 21.32, p = .13; CFI = .982, GFI = .976, RMSEA = .044) emphasizes the centrality of professional identifications to succeed in training. Women are less identified with sailor than men and feel less able to succeed, they develop lower performance expectations and they underestimate their performance compared to their colleagues, which has a negative effect on their success in training. In parallel, changes in family life are associated with reduced professional identifications, but this effect is independent of the sex of the individuals. Women are therefore exposed to two independent sources of influence limiting their career development: gender, which leads to less professional identifications and to compare unfavorably with their colleagues, and family status. These results highlight the importance of the dynamic of self-realization processes throughout the career.

A model of (often mixed) stereotype content: competence and warmth respectively follow from perceived status and competition

Stereotype research emphasizes systematic processes over seemingly arbitrary contents, but content also may prove systematic. On the basis of stereotypes' intergroup functions, the stereotype content model hypothesizes that (a) 2 primary dimensions are competence and warmth, (b) frequent mixed clusters combine high warmth with low competence (paternalistic) or high competence with low warmth (envious), and (c) distinct emotions (pity, envy, admiration, contempt) differentiate the 4 competence-warmth combinations. Stereotypically, (d) status predicts high competence, and competition predicts low warmth. Nine varied samples rated gender, ethnicity, race, class, age, and disability out-groups. Contrary to antipathy models, 2 dimensions mattered, and many stereotypes were mixed, either pitying (low competence, high warmth subordinates) or envying (high competence, low warmth competitors). Stereotypically, status predicted competence, and competition predicted low warmth.     

Learned suppression of photopositive tendencies in Drosophila melanogaster

A task was designed to teach individual flies to avoid a lighted area after they had displayed an initial preference for it. The flies walked in a T-maze and chose between a lighted and a darkened alley leading, respectively, to a lighted and a darkened vial. Flies that were photopositive on a first trial were subjected to an aversive stimulus (a filter paper inserted into the lighted vial and wetted with a quinine solution), and they performed 16 training trials; they learned to avoid the lighted vial. The flies trained with water instead of quinine in the lighted vial still display avoidance of the lighted vial, but to a lesser extent. The flies trained with a dry filter paper in the lighted vial did not show any increase in avoidance during training. Like the flies trained with no quinine at all, those trained to avoid the lighted vial under a partial reinforcement condition (one half of the trials with quinine, the other half with a dry vial) did not master the task. Finally, removal of the quinine after an avoidance acquisition criterion was reached resulted in an extinction process.     

Involvement of the medial prefrontal cortex in two alternation tasks using different environments

Spatial alternation performance in rats is usually evaluated with the T-Maze. The first aim of this study was to analyze the effect of a selective lesion of medial prefrontal cortex (mPFC) on performance in a T-maze. Second, we wanted to validate a new test using alternation in a water maze (AWM). The mPFC of 21 male Sprague-Dawley rats was lesioned bilaterally using in situ microinjection of ibotenic acid. Thirteen control rats received injections of the vehicle only. Results show that mPFC lesioned rats were significantly impaired in the T-Maze as well as in the AWM compared to controls. These results validate the AWM as a frontal cortex dependent task probing working memory and/or behavioral flexibility. We suggest that the AWM may be more powerful than the T-maze as an investigational tool, given that is can be easily compared to other water maze tasks that evaluate other (nonfrontal) cognitive modules.     

Letter binding and invariant recognition of masked words: behavioral and neuroimaging evidence

Abstract— Fluent readers recognize visual words across changes in case and retinal location, while maintaining a high sensitivity to the arrangement of letters. To evaluate the automaticity and functional anatomy of invariant word recognition, we measured brain activity during subliminal masked priming. By preceding target words with an unrelated prime, a repeated prime, or an anagram made of the same letters, we separated letter-level and whole-word codes. By changing the case and theretinal location of primes and targets, we evaluated the invariance of those codes. Our results indicate that an invariant binding of letters into words is achieved unconsciously through aseries of increasingly invariant stages in the left occipito-temporal pathway.
