Individual differences in 10‐month‐olds' performance on the A‐not‐B task

This study used the classical A‐not‐B task (Piaget, 1954 ) to explore individual differences in cognitive flexibility in 10‐month‐old infants by: (1) examining how differences in search performance during A trials relate to search performance during B trials; (2) studying the relation between temperamental dimensions and A‐not‐B performance; and (3) investigating differences in search performance between looking and reaching responses within the same task. Forty infants were tested on a fixed‐design‐version of the A‐not‐B task, not allowing for training or individual adjustment, but instead eliciting additional search behaviors than the common correct responses in A trials and perseverative errors in B trials. Infants were also rated by their parents on the temperamental scales Activity level and Attention span. The main findings were: (1) performance on A trials affected B trial performance, with infants being more correct on A trials having more incorrect and less ‘no search’ responses on B trials; (2) activity level, but not attention span, was related to performance on the A‐not‐B task, with infants performing better on A trials having a lower activity level; and (3) there were a few differences in performance with regard to modality, indicating that responding correctly by looking may be less cognitively demanding than doing so by reaching. This study demonstrated that 10‐month‐olds show a wide variation of search behaviors on this A‐not‐B task, resulting in individual differences in performance. These differences are suggested to reflect variation in temperamental activity level as well as maturity of short term/working memory, inhibition and cognitive flexibility.     

An atypical anxious‐impulsive pattern of social anxiety disorder in an adult clinical population

An atypical subgroup of Social Anxiety Disorder (SAD) with impulsive rather than inhibited traits has recently been reported. The current study examined whether such an atypical subgroup could be identified in a clinical population of 84 adults with SAD. The temperament dimensions harm avoidance and novelty seeking of the Temperament and Character Inventory, and the Liebowitz Social Anxiety Scale were used in cluster analyses. The identified clusters were compared on depressive symptoms, the character dimension self‐directedness, and treatment outcome. Among the six identified clusters, 24% of the sample had atypical characteristics, demonstrating mainly generalized SAD in combination with coexisting traits of inhibition and impulsivity. As additional signs of severity, this group showed low self‐directedness and high levels of depressive symptoms. We also identified a typically inhibited subgroup comprising generalized SAD with high levels of harm avoidance and low levels of novelty seeking, with a similar clinical severity as the atypical subgroup. Thus, higher levels of harm avoidance and social anxiety in combination with higher or lower levels of novelty seeking and low self‐directedness seem to contribute to a more severe clinical picture. Post hoc examination of the treatment outcome in these subgroups showed that only 20 to 30% achieved clinically significant change.     

Beliefs and environmental behavior: The moderating effect of emotional intelligence

Recent decades have seen a proliferation of studies aiming to explain how pro‐environmental behavior is shaped by attitudes, values and beliefs. In this study, we have included an aspect in our analysis that has been rarely touched upon until now, that is, the intelligent use of emotions as a possible component of pro‐environmental behavior. We applied the Trait Meta Mood Scale‐24 (TMMS‐24) and the New Environmental Paradigm scale to a sample of 184 male and female undergraduate students. We also carried out correlation and hierarchical regression analyses of blocks. The results show the interaction effects of the system of environmental beliefs and the dimensions of emotional intelligence on glass recycling attitudes, intentions and behavior. The results are discussed from the perspective of research on how the management of emotions guides thought and behavior.     

When in Rome… Identification and acculturation strategies among minority members moderate the dehumanisation of the majority outgroup

The study of humanness as a dimension of social judgment has received extensive attention over the past decade. Although the common reported finding is that people attribute more human characteristics to their ingroup than to the outgroup, similar tendencies are expected to be tempered for minority groups when judging the host society. In Study 1, carried out with Gypsy minority members, we tested the hypothesis that those group members who adopt an assimilative strategy identifying more with the host compared with the heritage culture will display the lowest levels of dehumanisation. In Studies 2 and 3, conducted with immigrants in Italy and in Portugal, respectively, the hypothesis was extended from an identification conceptualisation to an acculturation one. Despite significant variability in intergroup settings and measures, results confirmed our hypothesis that immigrants who choose to assimilate with the host culture dehumanise the outgroup less compared with those who adopt any of the other acculturation strategies. Implications for the ethnocentric nature of dehumanisation biases and for intergroup relations in general are discussed. Copyright © 2014 John Wiley & Sons, Ltd.     

Immobility reaction at birth in newborn infant

Objective

To describe an immobility reaction (IR) that was not previously reported at or immediately after birth in human newborns.

Method

We analyzed 31 videos of normal term vaginal deliveries recorded from Time 0 of birth defined as the as the moment that lies between the birth of the thorax and the pelvis of the infant. We searched for perinatal factors associated with newborn's IR.

Results

IR at birth was observed in 8 of the 31 newborns. The main features of their behavior were immobilization, frozen face, shallow breathing and bradycardia. One of the 8 newborns had sudden collapse 2 h after birth. We found significant relationships between maternal prenatal stress (PS) and IR (p = .037), and a close to significant one between infants’ lividness at Time 0 and IR (p = .053). The first breath of the 31 newborns occurred before and was not associated with the first cry (p < .001).

Discussion

The main features of IR at birth are similar to those of the universal most severe response to severe stress or danger. The relationship with PS suggests that children who had IR at birth might be at risk for similar disorders as those associated with PS. Sudden neonatal collapse of one of the IR newborns needs further research to determine if they are at risk for sudden infant death syndrome.

Conclusion

This first report of an IR reaction at birth in human infants could open up new paths for improving early neonatal care. Further research is needed for maternal PS, stress hormones, umbilical cord blood pH measurements in IR newborns. The challenge of education and support for parents of IR newborns is outlined.     

The subjective effort of everyday mental tasks: Attending,assessing, and choosing

Why are some mental tasks experienced as more effortful than others? Answers to this question about subjective effort have begun to be addressed by researchers investigating why some mental tasks are associated with more ‘elbow grease’ or ‘depletion’ than other tasks. It has been proposed that tasks such as sustained attention should be accompanied by more subjective effort than other tasks, such as assessing (e.g., counting a handful of items) or choosing randomly between two alternatives. In general, these proposals coincide with people’s intuitions regarding how effort should vary by mental task. However, little laboratory data have corroborated these conclusions. In two studies, we cataloged the relative amount of subjective effort associated with some basic and ubiquitous mental activities: attending (most subjective effort), assessing, and choosing (least subjective effort). Results support hypotheses about subjective effort. Because subjective effort is perceived to be experienced by a subject, we explored also the relationship between effort and the involvement of the ‘psychological self.’     

The notion of happiness in early Wittgenstein: towards a non-contentful account of happiness

This paper examines the notion of ‘happiness’ in the writings of the early Wittgenstein as a notion that does not involve any particular content or states of mind. The main question that the paper addresses is how we can retain a non-contentful account of happiness without turning happiness into an abstract notion, isolated from our concrete lives in language. The paper examines two pivotal components of the Wittgensteinian account of happiness: the ‘good exercise of the will’ and the ‘artistic way of seeing’. In both cases, I try to stress their non-contentful dimension, while simultaneously trying to understand them through language. The central concept for such a non-contentful aspect of language is the notion of ‘meaningfulness’. Thus the paper examines the pivotal components of the Wittgensteinian account of happiness in relation to the notion of ‘meaningfulness’: happiness is then explained as seeing a world against the background of possibilities of meaning.     

BDNF serum levels in subjects developing or not post-traumatic stress disorder after trauma exposure

Post-traumatic stress disorder (PTSD) is a syndrome resulting from exposure to a severe traumatic event that poses threatened death or injury and produces intense fear and helplessness. The neural structures implicated in PTSD development belong to the limbic system, an important region for emotional processing. Brain-derived neurotrophic factor (BDNF) is a neurotrophin that serves as survival factor for selected populations of central nervous system (CNS) neurons and plays a role in the limbic system by regulating synaptic plasticity, memory processes and behavior. Impaired BDNF production in the brain can lead to a variety of CNS dysfunctions including symptoms associated with PTSD. However, so far fewer studies have investigated this neurotrophin in patients with PTSD. Furthermore, given the multiple role of BDNF in various CNS disorders, it cannot be excluded that traumatic events per se may influence neurotrophin levels, without a direct association to the PTSD syndrome.     

Children Use Temporal Cues to Learn Causal Directionality

The ability to learn the direction of causal relations is critical for understanding and acting in the world. We investigated how children learn causal directionality in situations in which the states of variables are temporally dependent (i.e., autocorrelated). In Experiment 1, children learned about causal direction by comparing the states of one variable before versus after an intervention on another variable. In Experiment 2, children reliably inferred causal directionality merely from observing how two variables change over time; they interpreted Y changing without a change in X as evidence that Y does not influence X. Both of these strategies make sense if one believes the variables to be temporally dependent. We discuss the implications of these results for interpreting previous findings. More broadly, given that many real‐world environments are characterized by temporal dependency, these results suggest strategies that children may use to learn the causal structure of their environments.
