The beneficial and detrimental effects of major depression on intuitive decision-making

Intuitions play a central role in everyday life decision-making but little is known regarding this capacity during depression. Thus, in Study 1, N?=?39 depressed in-patients completed two well-established tasks, assessing intuitions of visual and semantic coherence. In the semantic coherence task, patients judged whether presented words triads were coherent (e.g. SALT DEEP FOAM, related to SEA) or not (e.g. DREAM BALL BOOK, no denominator). In the visual coherence task, patients judged whether blurred pictures depicted real-life objects (coherent) or not (incoherent). Results showed that higher depressive symptomatology was associated with impaired intuitions of semantic coherence but with enhanced intuitions of visual coherence. In Study 2, visual coherence intuitions of depressed patients (n?=?27) were compared to healthy control participants (n?=?30). Depressed patients outperformed the healthy control subjects in the visual coherence task. This pattern of findings shows both detrimental and beneficial decisional consequences of depression.     

Parental and school effects on students' occupational exploration: A longitudinal and multilevel analysis

The study examines school and parental influences on adolescents' occupational exploration. Analyses of data from 859 6th, 8th, and 10th graders attending high- and lower-track high schools in the German federal state of Thuringia suggested more extensive exploration among students closer to the school-to-work transition. Besides cross-sectional effects of parenting and achievement orientation at school, acceptance and openness students experienced in class predicted increases of their exploratory behaviors. Multilevel analyses showed, however, that school effects operated on the level of subjective perceptions (individual level), but not on the level of intersubjective reality (classroom level). Implications for attempts to foster and facilitate exploration are discussed.     

Infant's perception of goal-directed actions performed by a mechanical device

The present work investigated whether by the end of the first year, infants interpret actions performed by a mechanical device as goal-directed and why they would do so. Using a modified version of the Woodward (1998) habituation paradigm, 9- and 12-month-old infants were tested in a condition in which they saw a mechanical claw performing an action (Study 1). When infants viewed the claw grasping and transporting objects to the back of a stage, 12-month-old but not 9-month-old infants interpreted the action as goal-directed. In Study 2, 9-month-olds received prior to habituation an information phase showing infants how a human held and operated the claw. This enrichment of infants’ knowledge enabled 9-month-old infants to interpret the action display as goal-directed. The role of the developing means-end understanding and tool-use for infants’ interpretation of actions performed by a mechanical device is discussed.     

Multiple citizenship and naturalization: An evaluation of German and Dutch policies

In many countries the trend has been toward greater acceptance of multiple citizenship and more naturalizations of immigrants. This article analyses and compares developments in Germany and the Netherlands. Central questions are how policies toward dual citizenship have developed and to what extent these policies have influenced naturalization rates. The far-reaching toleration of dual citizenship in the Netherlands in the 1990s resulted in high naturalization rates. However, there were large differences between immigrant groups. Similar differences are found in Germany. Multiple citizenship carries little importance for European Union (EU) citizens, who feel no need to naturalize, and for refugees, who have no desire to retain the citizenship of their country of origin.     

The link between infant attention to goal‐directed action and later theory of mind abilities

Various studies have shown that infants in their first year of life are able to interpret human actions as goal‐directed. It is argued that this understanding is a precondition for understanding intentional actions and attributing mental states. Moreover, some authors claim that this early action understanding is a precursor of later Theory of Mind (ToM) development. To test this, we related 6‐month‐olds’ performance in an action interpretation task to their performance in ToM tasks at the age of 4 years. Action understanding was assessed using a modified version of the Woodward‐paradigm ( Woodward, 1999 ). At the age of 4 years, the same children were tested with the German version of the ToM scale developed by Wellman and Liu (2004 ). Results revealed a correlation between infants’ decrement of attention to goal‐directed action and their ability to solve a false belief task at the age of 4 years with no modulation by language abilities. Our results indicate a link between infant attention to goal‐directed action and later theory of mind abilities.     

Twin-singleton differences in intelligence: a meta-analysis

Since the emergence of twin studies in the 1920s, time and again the question of possible twin-singleton differences in intelligence has been posed. This study addressed the issue through a meta-analysis of published studies on this theme. Twins on the average seem to have lower IQs than singletons. The best estimate for this group difference is 4.2 IQ points (less than one-third of a standard deviation), with a great divide between study outcomes of less vs more recent birth cohorts (5.1 vs 0.5 IQ points, respectively). The evidence is based on studies from six countries (including population-based ones of entire birth cohorts), a massive database (comparisons of more than 30,000 twins with nearly 1.6 million singletons), a variety of intelligence tests, and birth cohorts spanning most of the 20th century, but, for the most part, on an age range limited to children and adolescents. The effect shows considerable between-study heterogeneity but appears robust (fail-safe N calculations), not due to influential individual studies (sensitivity analysis) or publication bias, was present since the very first published studies (cumulative meta-analysis), and appears generalizable across sex, zygosity, and other intelligence domains beyond the verbal. There are insufficient data as to whether the effect persists over the lifespan, exists as well within families, or has ceased in recent birth cohorts of highly developed countries (Denmark and The Netherlands). Likely causes of the effect appear to be prenatal and perinatal factors (reduced fetal growth and shorter gestation for twins).     

Who's to blame? Narcissism and self‐serving attributions following feedback

The study examined the relationship between narcissism, performance attributions, and negative emotions following success or failure. As expected, narcissistic individuals showed more self‐serving attributions for their performance in an intelligence test than less narcissistic individuals: compared with less narcissistic individuals, narcissists revealed a stronger tendency to attribute success to ability and failure to task difficulty. In contrast to this, less narcissistic participants tended to show the opposite pattern by ascribing failure, but not success, to their ability. Additionally, anger and depression could be predicted by an interaction of performance feedback and performance attributions. Mediation analyses revealed that the attribution dimensions ‘task difficulty’ and ‘ability’ mediated the effect of narcissism on anger and depression following failure feedback. The results provide support for the theoretical assumption that attributional processes might, at least to some extent, explain the often reported relation between narcissism and negative emotions following failure.

The Salvational Process in Relationships: A View from Projective–Introjective Identification and Repetition Compulsion

On the basis of mechanisms such as projective–introjective identification, basic affect, affect regulation, and repetition compulsion, we shall try to explain the essence of intrapsychic, interpersonal, and relational family dynamics. We will also try to explain how relational connections mutually intertwine in the family system, what sustains them, and why they are created and recreated again and again. It is in this regard that we will also be able to consider the essential salvational process, which occurs precisely on the basis of these mechanisms, that is, those that represent fundamental purification and salvation. Some basic biblical theological concepts are applied. These provide the basis for integrating the psychological and theological domains of family systems.     

Explanatory pluralism in cognitive science

This brief commentary has three goals. The first is to argue that "framework debate" in cognitive science is unresolvable. The idea that one theory or framework can singly account for the vast complexity and variety of cognitive processes seems unlikely if not impossible. The second goal is a consequence of this: We should consider how the various theories on offer work together in diverse contexts of investigation. A final goal is to supply a brief review for readers who are compelled by these points to explore existing literature on the topic. Despite this literature, pluralism has garnered very little attention from broader cognitive science. We end by briefly considering what it might mean for theoretical cognitive science.
