Pilot study of light therapy and neurocognitive performance of attention and memory in healthy subjects

The aim of this pilot study was to investigate whether light therapy improves healthy subjects' neurocognitive performance of attention, memory, and language. Ten subjects were treated with white bright light for 5 days and a control group of 10 with no treatment were assessed with a battery of neurocognitive tests which included the Stroop Colour Word Interference Test, the Verbal Fluency Test, the Story Recall Test, and the Word Pairs Recall Test. Analysis showed improvements in cognitive scores in both groups, although on all the cognitive tests the mean difference scores between baseline and endpoint were significantly larger in the light-treated group. These preliminary results suggest that short-term bright light may exert beneficial effects on cognitive functions.     

Interference risk and the function of dynamic shifts in calling in the gray treefrog (Hyla versicolor)

Male gray treefrogs call to attract females under challenging acoustic conditions. At higher chorus densities, there is considerable background noise and a good chance that a male's calls will often be overlapped by calls of other individuals. Call overlap may reduce the probability of mating because females prefer calls with internal pulse structure that is not obscured. With increases in acoustic stimulation, males lengthen call duration while simultaneously reducing call rate such that "pulse effort" changes little. In our study, we tested the "interference risk hypothesis." This proposes that males change call duration so that, on average, there will be a sufficient number of pulses and interpulse intervals clear of acoustic interference per call to attract a female. However, female choice experiments employing call alternatives of different durations, rates, intensity levels, and degrees of call overlap refuted this hypothesis. Our results leave open the possibilities that the dynamic shift in the two components of pulse effort are related to the problem of call detection in a noisy environment or are responses by males to the perceived threat of competition for females.     

We are one and I like it: The impact of ingroup entitativity on ingroup identification

It is argued that the entitativity of the ingroup moderates the level of identification with the ingroup. Specifically, that high levels of entitativity are conducive to strong identification, whereas low levels of entitativity reduce identification with the ingroup. These hypotheses were tested across four studies using the European Union (EU) as the reference group. The four studies manipulated four different factors that, according to Campbell (1958), impact on group entitativity: common fate (Study 1), similarity (Study 2), salience (Study 3), and boundedness (Study 4). Across the four studies, we found evidence for the impact of these factors on the level of identification with the EU among European citizens holding moderate attitudes toward the EU but not (or much less) for citizens holding more extreme attitudes towards the EU. Mediational analyses further confirmed the viability of an entitativity‐based interpretation of the impact of the manipulations on the level of identification. The findings are discussed in light of the current debate on the concept of entitativity, the motives for social identification, and the reduction of ingroup bias.

The Perception of the Other in International Relations: Evidence for the Polarizing Effect of Entitativity

In an international relations context, the mutual images held by actors affect their mutual expectations about the Other's behavior and guide the interpretation of the Other's actions. Here it is argued that the effect of these images is moderated by the degree of entitativity of the Other—that is, the extent to which it is perceived as a real entity. Two studies tested this hypothesis by manipulating the entitativity of the European Union (EU) among U.S. citizens whose images of the EU varied along the enemy/ally dimension. Results of these studies yielded converging evidence in support of the hypothesized moderating effect of entitativity. Specifically, entitativity showed a polarizing effect on the relationship between the image of the EU and judgments of harmfulness of actions carried out by the EU.     

To do or not to do? Prospective memory versus response inhibition in autism spectrum disorder and attention-deficit/hyperactivity disorder

In the present research, event-based prospective memory and response inhibition (RI) abilities were investigated in children with ASD (Study 1), with ADHD (Study 2), and their matched neurotypical controls. Children engaged in a categorisation (ongoing) task and, concurrently, in either an event-based prospective memory (PM) or a Go/No-Go secondary task. Results showed that, as compared to their matched controls, ASD children's performance was more impaired in the PM task than in the Go/No-Go task, while the performance pattern of ADHD children was reversed. In the ongoing task, ASD children were as accurate as, but significantly slower than, controls, independently of conditions. ADHD children did not differ from controls in the presence of a concurrent PM task, while they were less accurate than controls in the presence of the go/no-go task. Overall, the two patterns of findings suggest important differences in the way ASD and ADHD children remember and realise intentions requiring opposite behaviours (acting vs stopping).     

Exploring the Link Between Mind Wandering,Mindfulness, and Creativity: A Multidimensional Approach

Even if mind wandering (MW) and mindfulness have traditionally been intended as separate and antithetical constructs, the roles of these 2 mental states on creative behavior were jointly explored in this article. In particular, MW was analyzed in light of a recent approach suggesting a differentiation between deliberate and spontaneous MW, whereas mindfulness was analyzed by distinguishing its 5 different constitutional dimensions: observing, acting with awareness, describing, nonreactivity, and nonjudging. The influence on creativity of these 2 mental states was analyzed using a sample of 77 undergraduate students both on a performance index (i.e., originality) and on a self-report index (i.e., creative achievement). Results showed that MW and mindfulness dimensions predicted creative behavior both alone and in combination, suggesting a complex interdependence between these 2 mental states within the creative thinking process. In particular, the critical importance of distinguishing between deliberate and spontaneous MW was revealed by a final path analysis, which revealed the opposite effects of these 2 dimensions on originality and creative achievement. That is, deliberate MW positively predicted creative performance, whereas spontaneous MW was negatively associated with such performance. Moreover, the nonreactivity and awareness dimensions of mindfulness, the latter in interaction with deliberate MW, emerged as main predictors of response originality. Finally, the describing facet of mindfulness predicted creative achievement both directly and indirectly through an interaction with deliberate MW. The implications emerging from the adoption of a multi-dimensional approach to the analysis of MW and mindfulness in the study of creativity are discussed herein.     

THE COUNTERTRANSFERENCE: EROTIC,EROTISED AND PERVERSE3

The author begins by drawing attention to the dearth of psychoanalytic theory on the sexual countertransference, which he attributes largely to embarrassment associated with the personal superego and to fear of censure by the psychoanalytic community. After a review of the relevant literature, he points out that the term ‘countertransference’ arose in the context of misbehaviour by the early analysts and that the countertransference was originally seen as something to be controlled and suppressed, partly for the sake of the reputation of psychoanalysis. Theoretical and normative reasons are adduced for the disappearance of sexuality from psychoanalytic scenarios, and the wish for sexual contact with patients is discussed. While it may be deemed perfectly normal for an analyst to have erotic feelings towards patients of either sex, psychopathology is, in the author's view, involved only if he acts out. Clinical illustrations are given of manifestations of the sexual countertransference in its erotic, erotised and perverse forms, which the author considers it important to distinguish. He concludes that the relative absence of theory on the subject means that not enough clinical use is made of the sexual countertransference, which he sees as of great potential value to therapist and patient alike.     

The role of visuo-spatial working memory in map learning: new findings from a map drawing paradigm

Recently, increasing attention has been devoted to the study of the role of visuo-spatial working memory (VSWM) in environmental learning and spatial navigation. The present research was aimed at investigating the role of VSWM in map learning using a map drawing paradigm. In the first study, a dual task methodology was used. Results showed that map drawing was selectively impaired by a spatial tapping task that was executed during the map learning phase, hence supporting the hypothesis that VSWM plays an essential role in learning from maps. In the second study, using a correlational methodology, it was shown that performance in simultaneous VSWM tasks, but not in sequential VSWM tasks, predicted map drawing skills. These skills “in turn” correlated with map learning abilities. Finally, in the third study, we replicated the results of the second study, by using a different map. To our knowledge, the present study is the first to find evidence that the simultaneous aspects of VSWM play a fundamental role in learning from maps.     

Sedative effects of intergroup contact on support for ethnic activism among Kosovo Albanians in Switzerland: The interplay of ethnic,national, and dual identification

A large body of research has demonstrated that intergroup contact is a powerful tool for reducing prejudice among majority group members. Yet, research among minority group members has revealed a more complex picture. The present contribution advances recent research on sedative effects of intergroup contact on support for ethnic activism, by investigating how identity dynamics undermine ethnic minorities' claims for better conditions and equal rights. More precisely, we disentangled the mediating roles played by reduced ethnic and increased national identification as a consequence of intergroup contact, while considering the moderating role of dual identification. Results from a cross-sectional study among an understudied immigrant minority, Kosovo Albanians in Switzerland, indicate that dual identification moderated the sedative effect of intergroup contact on support for ethnic activism via decreased ethnic identification, while no support for conditional processes of intergroup contact via increased national identification were found. Intergroup contact was linked to reduced ethnic identification, which in turn related to increased support for ethnic activism, but only when dual identification was low. Conversely, when dual identification was high, ethnic identification was unrelated to support for ethnic activism, and intergroup contact reduced ethnic activism directly. To conclude, we discuss the mobilizing role of dual identification, and reflect on how ethnic and national components of dual identities affect the politicization of stigmatized minorities.
