Atheism is only skin deep: Geertz and Markússon rely mistakenly on sociodemographic data as meaningful indicators of underlying cognition

Cognitive scientists of religion and evolutionary theorists alike have been increasingly arguing in recent years that religion is “natural” in the sense of being motivated by core, evolved psychological intuitions. Atheism, and irreligion more generally, appear to pose problems for the naturalness hypothesis, especially considering the significant proportion of people in contemporary societies who reject supernatural beliefs. Although Geertz and Markússon clarify why the naturalness hypothesis does not imply religious determinism, they fail to weigh adequately the more conservative prediction, that of religious probabilism. Furthermore, unlike cognitive scientific accounts favoring the naturalness hypothesis, the authors base their arguments for the cultural scaffolding of atheistic cognition on sociodemographic data alone—a source that is unlikely to be a meaningful reflection of “natural” underlying cognitive processes.     

Contribution de la motricité graphique à la reconnaissance visuelle des lettres

The ability to recognize single letters, an important step in reading, is traditionally assumed to depend only on visual processes. However, as many of the objects surrounding us, letters are learnt through a matching between a visual configuration and movements. We review arguments suggesting that the characteristics of writing movements impact visual recognition of letters, at both a behavioral and neural levels. This impact might be especially strong when the orientation of letters has to be processed.     

Neurocognitive correlates of white matter quality in adolescent substance users

Background

Progressive myelination during adolescence implicates an increased vulnerability to neurotoxic substances and enduring neurocognitive consequences. This study examined the cognitive manifestations of altered white matter microstructure in chronic marijuana and alcohol-using (MJ + ALC) adolescents.

Methods

Thirty-six MJ + ALC adolescents (ages 16–19) and 36 demographically similar controls were evaluated with diffusion tensor imaging (Bava et al., 2009) and neurocognitive tests. Regions of group difference in fractional anisotropy (FA) and mean diffusivity (MD) were analyzed in relation to cognitive performance.

Results

In users, lower FA in temporal areas related to poorer performance on attention, working memory, and speeded processing tasks. Among regions where users had higher FA than controls, occipital FA was positively associated with working memory and complex visuomotor sequencing, whereas FA in anterior regions was negatively associated with verbal memory performance.

Conclusions

Findings suggest differential influences of white matter development on cognition in MJ + ALC using adolescents than in non-using peers. Neuroadaptation may reflect additive and subtractive responses to substance use that are complicated by competing maturational processes.     

White matter development during adolescence as shown by diffusion MRI

Previous volumetric developmental MRI studies of the brain have shown white matter development continuing through adolescence and into adulthood. This review presents current findings regarding white matter development and organization from diffusion MRI studies. The general trend during adolescence (age 12–18 years) is towards increasing fractional anisotropy (FA) with age and decreasing mean diffusivity (MD) with age, findings primarily due to decreasing radial diffusivity with age. However, results of studies vary as to the regional specificity of such age-related changes, likely due in part to methodological issues. Another general trend is for FA to positively correlate and MD to negatively correlate with cognitive function. This trend is however region-specific, task-specific, and population-specific; some studies have in fact found negative correlations of FA and positive correlations of MD in specific regions with specific measures of cognitive performance. There are also published reports of sexual dimorphism in white matter development, indicating differing developmental trajectories between males and females as well as differing relationships developmentally between white matter architecture and cognitive function. There is a need for more research to further elucidate the development of white matter and its relation to cognitive function during this critical developmental period.     

Perfectionism, Cognition, and Affect in Response to Performance Failure vs. Success

The current paper describes the results of an experiment in which 200 students who varied in levels of trait perfectionism performed a laboratory task of varying levels of difficulty. Participants received either negative or positive performance feedback, independent of their actual level of performance. Analyses of pre-task and post-task measures of negative and positive affect showed that individuals with high self-oriented perfectionism experienced a general increase in negative affect after performing the task, and self-oriented perfectionists who received negative performance feedback were especially likely to report decreases in positive affect. Additional analyses showed that self-oriented perfectionists who received negative feedback responded with a cognitive orientation characterized by performance dissatisfaction, cognitive rumination, and irrational task importance. In contrast, there were relatively few significant differences involving other-oriented and socially prescribed perfectionism. Collectively, our findings support the view that self-oriented perfectionism is a vulnerability factor involving negative cognitive and affective reactions following failure experiences that reflect poorly on the self.     

Cognitive reactivity to sad mood: structure and validity of a new measure.

Cognitive reactivity to the experimental induction of sad mood has been found to predict relapse in recovered depressed patients. The present report describes the development and test of a questionnaire that aims to measure cognitive reactivity independently from a mood induction procedure. The Leiden Index of Depression Sensitivity (LEIDS) was filled out by 198 participants. After Principal Components Analysis, 26 items were retained, which comprised four factors with good psychometric properties: Negative Self-Evaluation; Acceptance/Coping; Indifference; and Harm Avoidance. In a sample of 48 college students, LEIDS scores--particularly Negative Self-Evaluation and Harm Avoidance--were rather strong predictors of cognitive reactivity in a mood induction procedure. In contrast, baseline depression and baseline cognitive dysfunction did not predict cognitive reactivity. It is concluded that the LEIDS is a promising measure of cognitive reactivity, and that clinical studies need to be carried out to test its ability to predict relapse of depression.     

情绪的神经心理学理论概述

本文主要论述了情绪神经心理学的有关理论。过去,人们认为情绪和认知分别由皮层下和皮层结构所控制,认知系统控制着情绪系统。现在,人们认为认知和情绪两个机能系统是相互联系的。情绪系统能快速、自动地加工有限数量的信息,认知系统则能有意识和有控制地分析信息。情绪是一个非同质的、多成分的、有等级组织的适应系统。大脑左、右半球在情绪表征和控制中具有不对称性,右半球主要控制自动的、自发的情绪,而左半球在概念水平上调节控制情绪。     

Rigidity of the far‐right? Motivated social cognition in a nationally representative sample of Hungarians on the eve of the far‐right breakthrough in the 2010 elections

We investigated the “rigidity of the right” hypothesis in the context of the far‐right breakthrough in the 2010 Hungarian parliamentary elections. This hypothesis suggests that psychological characteristics having to do with need for security and certainty attract people to a broad‐based right‐wing ideology. A nationally representative sample (N = 1000) in terms of age, gender and place of residence was collected by means of the random walking method and face‐to‐face interviews. Voters of JOBBIK (n = 124), the radically nationalist conservative far‐right party, scored lower on System Justifying Belief, Belief in a Just World (Global) and higher on Need for Cognition than other voters. Our results contradict the “rigidity of the right” hypothesis: JOBBIK voters scored, on many measures, opposite to what the hypothesis would predict.     

Psychologie du frisson esthétique

This study concerns the problem of aesthetic emotions and that of aesthetic chills in particular. We asked thirty subjects to describe a narrative structure (film, play, book) eliciting chills and the phenomenology of the aesthetic experience. A number of non-random redundancies are observable. The stimuli eliciting positive aesthetic chills in our population have a sensorial dimension and their particular properties are often the selfless actions, existential considerations of a very general nature (e.g., the meaning of life), moments of inner recollection or quiet reflection, situations of solidarity and communion (family, couple, friends) or, on the contrary, situations of violent separation (family, couple, friends). In general, when real events are at stake (and not fictional scenes as in a film or a novel), subjects describe situations where they are safe, where they trust the environment.
