Prenatal Representations of Family in Parents and Coparental Interactions as Predictors of Triadic Interactions During Infancy

In this study, we explored the predictive role of family interactions and family representations in mothers and fathers during pregnancy for postnatal mother–father–infant interactions during the first 2 years after birth. Families (N = 42) were seen at the fifth month of pregnancy and at 3 and 18 months after birth. During pregnancy, parents were asked to play with their baby at the first meeting by using a doll in accordance with the procedure of the prenatal Lausanne Trilogue Play (LTP; A. Corboz‐Warnery & E. Fivaz‐Depeursinge, 2001; E. Fivaz‐Depeursinge, F. Frascarolo‐Moutinot, & A. Corboz‐Warnery, 2010). Family representations were assessed by administering the Family System Test (T. Gehring, 1998). Marital satisfaction and the history of the couple were assessed through self‐reported questionnaires. At 3 and 18 months, family interactions were assessed in the postnatal LTP. Infant temperament was assessed through parent reports. Results show that (a) prenatal interactions and child temperament are the most important predictors of family interactions and (b) paternal representations are predictive of family interactions at 3 months. These results show that observational assessment of “nascent” family interactions is possible during pregnancy, which would allow early screening of family maladjustment. The findings also highlight the necessity of taking into account paternal representations as a significant variable in the development of family interactions.     

REFEREES' DECISION MAKING ABOUT TRANSGRESSIONS: THE INFLUENCE OF PLAYER GENDER AT THE HIGHEST NATIONAL LEVEL

Prior research has found that referees are harsher toward sporting offenses in regional-level matches between women than in regional-level matches between men. We tested whether this bias also occurs at a higher, national level of competition, despite the greater pressures for objectivity and fairness at this level. Referees' decisions were examined in 15 national-level handball matches between women and 15 national-level handball matches between men after transgressions that varied in severity. The results suggest that referees made harsher decisions in female than in male matches. Although more research is needed, this study supported the hypothesis that referees may use the gender of players as a powerful judgmental heuristic for deciding how to respond to aggression.     

Role of L-type Ca2+ channel isoforms in the extinction of conditioned fear

Dihydropyridine (DHP) L-type Ca(2+) channel (LTCC) antagonists, such as nifedipine, have been reported to impair the extinction of conditioned fear without interfering with its acquisition. Identification of the LTCC isoforms mediating this DHP effect is an essential basis to reveal their role as potential drug targets for the treatment of specific anxiety disorders. Ca(V)1.2 and Ca(V)1.3 are the predominant LTCCs in the mammalian brain. However, since no isoform-selective DHP blockers are available, their individual contribution to fear memory extinction is unknown. We used a novel mouse model expressing DHP-insensitive Ca(V)1.2 LTCCs (Ca(V)1.2DHP(-/-) mice) to address this question. In line with previous studies, wild-type (WT) mice treated with systemic nifedipine displayed markedly impaired fear extinction. This DHP effect was completely abolished in Ca(V)1.2DHP(-/-) mice, indicating that it is mediated by Ca(V)1.2, but not by Ca(V)1.3 LTCCs. Supporting this conclusion, Ca(V)1.3-deficient mice (Ca(V)1.3(-/-)) showed extinction identical to the respective WT mice. The inhibition of fear extinction was not observed after intracerebroventricular (i.c.v.) application of different doses of nifedipine, suggesting that this effect is secondary to inhibition of peripheral Ca(V)1.2 channels. The LTCC activator BayK, which lacks neurotoxic effects in Ca(V)1.2DHP(-/-) mice, did not influence the extinction time course. In summary, we demonstrate that LTCC signaling through the Ca(V)1.2 isoform of LTCCs interferes with fear memory extinction, presumably via a peripherally mediated mechanism. Activation of other LTCC isoforms (predominantly Ca(V)1.3) is not sufficient to accelerate extinction of conditioned fear in mice.     

First came the trees, then the forest: developmental changes during childhood in the processing of visual local-global patterns according to the meaningfulness of the stimuli

This study investigated how global and local perceptual processes evolve during childhood according to the meaningfulness of the stimuli. Children had to decide whether visually presented pairs of items were identical or not. Items consisted of global forms made up of local forms. Both global and local forms could represent either objects or nonobjects. In dissimilar pairs, items differed at one level (target level), while the other level included similar forms on both sides (irrelevant level). The results indicate an evolution from local preference at 4 years of age to adult-like global preference at 9 years of age. Moreover, as previously reported in adults, regardless of age, identification impaired performance when the irrelevant level was made of objects and the target level was made of nonobjects (interference). However, in younger children, this interference existed even when objects were present at all levels, suggesting that the strategy used to perform the comparison task also varied according to age.     

Eye color as an indicator of behavior: revisiting Worthy and Scott

Phenotypic eye color has been suggested as an indicator of genetic predisposition toward certain behaviors both in humans and in animals. Previous research has yielded mixed results. Phototaxic and ethological behaviors were examined in 14 different strains of Drosophila melanogaster. No significant correlation between phenotypic eye coloration and behavior was found, although significant genotypical behavioral differences were noted even among subjects with similar eye colors. An analysis of cellular defects associated with eye color in D. melanogaster pointed to significant behavioral differences among cell-defect groups, indicating that the cell defect which causes eye color, rather than eye color itself, may serve as a crude indicator of behavior.     

Compensation versus halo: the unique relations between the fundamental dimensions of social judgment

Recent work on the relations between the two dimensions of social judgment, that is, warmth and competence, evidenced compensation such that a group seen more positively than another group on one dimension is seen less positively on the second. The authors examine the status of this compensatory relation by introducing a third dimension in the judgment context. Experiment 1 extends earlier work in a different population, comparing compensation as a function of whether warmth or competence is manipulated and competence or warmth is the unmanipulated dimension. Experiments 2 and 3 use healthiness as the unmanipulated dimension and reveal the presence of halo rather than compensation between warmth or competence on one hand and healthiness on the other. These findings suggest that compensation may not only stem from a concern for distributive justice but may also derive from the unique structural and functional relations between the two fundamental dimensions of social judgment.     

I Will Put My Law in Their Minds: Social Control and Cheating Behavior Among Catholics and Protestants

Catholics and Protestants differ in terms of social autonomy versus heteronomy. We propose that the regulation of behavior in accordance with social norms depends on the social control exercised by an authority for Catholics more than it does for Protestants. Two experiments measured cheating behavior (the transgression of a social norm) as a function of the religious group (Protestant vs. Catholic) and social control (with vs. without). Catholics were found to be more responsive to social control, that is, to cheat less when social control was salient, whereas Protestants' behavior did not depend on this dimension. In Study 2, intrinsic‐extrinsic religiousness was found to mediate this difference. Results are discussed in the context of the effects of public policies based on social control.     

Secondary distinctiveness effects: Orthographic distinctiveness and bizarreness effects make independent contributions to memory performance

The secondary distinctiveness effect means that items that are unusual compared to one's general knowledge stored in permanent memory are remembered better than common items. This research studied two forms of secondary‐distinctiveness‐based effects in conjunction: the bizarreness effect and the orthographic distinctiveness (OD) effect. More specifically, an experiment investigated in young adults a possible additive effect of bizarreness and OD effects in free recall performance. Results revealed that in young adults these two secondary‐distinctiveness‐based effects appear to be largely independent and can complement each other to enhance performance. Findings are discussed in light of current distinctiveness theory.     

With a Little Help From Adults: Positive Emotion as an Excuse for Underage Drinking

This study provides an empirical demonstration that people’s reaction to youth drinking are influenced by the alleged motive for drinking and that regulations can easily be violated as soon as the perceived motive for underage liquor drinking is a positive emotion. The study solicited 432 passersby (50% men) to buy hard liquor for a female confederate allegedly younger than the minimum legal drinking age in France. Results showed that participants complied more frequently with the request when the motive for drinking was related with positive emotion.
