Religious authority and the transmission of abstract god concepts

According to the Standard Model account of religion, religious concepts tend to conform to “minimally counterintuitive” schemas. Laypeople may, to varying degrees, verbally endorse the abstract doctrines taught by professional theologians. But, outside the Sunday school exam room, the implicit representations that tend to guide people’s everyday thinking, feeling, and behavior are about minimally counterintuitive entities. According to the Standard Model, these implicit representations are the essential thing to be explained by the cognitive science of religion (CSR). It is argued here that this theoretical orientation of mainstream CSR misses a whole dimension of religiosity—the acceptance of certain religious authorities, that is, the acceptance of other people’s superior expertise. Average believers (especially in doctrinal traditions) tend to accept the authority of religious experts who espouse highly counterintuitive ideas that they (the laypeople) understand in a distorted form, if at all. These highly counterintuitive ideas are culturally successful because laypeople see them as being justified by people they have reason to regard as epistemic authorities. The tendency for people to endorse (without fully understanding) highly counterintuitive religious ideas espoused by intellectuals may explain parallels in the development of separate traditions (e.g., Judaism and Hinduism), as religious philosophers follow parallel lines of reasoning.     

Clinical and functional correlates of processing speed in pediatric Attention-Deficit/Hyperactivity Disorder: a systematic review and meta-analysis

It is well established that processing speed is negatively impacted in children and adolescents with Attention-Deficit/Hyperactivity Disorder (ADHD). Unfortunately, exactly how processing speed vulnerabilities manifest in daily functioning has not been well established. To support clinical care of youth with ADHD, it is important to better understand the functional consequences and relevant outcomes associated with processing speed deficits. This systematic review and meta-analysis sought to identify the association between processing speed and clinical or functional correlates among children or adolescents diagnosed with ADHD. A total of 409 abstracts were screened, of which, 60 full-text articles were identified as potentially relevant, and 8 of these studies met inclusion criteria. Domains evaluated across these studies included reading skills, mathematics skills, written expression, anxiety, self-appraisals of competence, and adaptive functioning. Six studies reported an association between processing speed and reading skills, allowing for meta-analysis. Processing speed difficulties among youth with ADHD appear strongly associated with several clinical and functional correlates including weaker academic skills, poorer adaptive skills, increased self-reported anxiety, and overestimates of social competence. Meta-analytic results for studies reporting the association between processing speed and reading skills indicate a medium overall weighted mean effect size (r = 0.33, 95% CI = 0.28 –0.39) with minimal heterogeneity (I² = 0.17). Clinical implications of these findings, limitations in the current knowledge base, and suggestions for future research are discussed.     

Aggression is associated with greater subsequent alcohol consumption: A shared neural basis in the ventral striatum

Alcohol use and abuse (e.g., binge drinking) are among the most reliable causes of aggressive behavior. Conversely, people with aggressive dispositions (e.g., intermittent explosive disorder) are at greater risk for subsequent substance abuse. Yet it remains unknown why aggression might promote subsequent alcohol use. Both aggressive acts and alcohol use are rewarding and linked to greater activity in neural reward circuitry. Through this shared instantiation of reward, aggression may then increase subsequent alcohol consumption. Supporting this mechanistic hypothesis, participants’ aggressive behavior directed at someone who had recently rejected them, was associated with more subsequent beer consumption on an ad‐lib drinking task. Using functional MRI, both aggressive behavior and beer consumption were associated with greater activity in the bilateral ventral striatum during acts of retaliatory aggression. These results imply that aggression is linked to subsequent alcohol abuse, and that a mechanism underlying this effect is likely to be the activation of the brain's reward circuitry during aggressive acts.

     

Human Chances for Happiness: A Review of Freud’s Civilization and Its Discontents

Sigmund Freud referred to his Civilization and Its Discontents (Freud 1930/1961) as an “inquiry concerning happiness.” In this article we discuss what he has to say about happiness. We focus on the reasons he gives for why lasting happiness is impossible to realize; his view that human beings tend to give precedence to the reduction of suffering over the desire for happiness; his suggestion that the best path to follow for what degrees of happiness are realizable depends on the individual; his view that pleasurable experiences are the basis for happiness and that no pleasures are comparable to that which occurs when one’s love is reciprocated by the other; the importance he places on the conflict between genital love and aim-inhibited forms of libidinal connection; his view that civilization plays a doubtful role as far as the realization of personal happiness is concerned; and his view of the role that human aggression and the sense of guilt play in promoting the unhappiness of civilized people. We conclude by offering seven comments on Freud’s views on the chance for human happiness.     

Path analysis of exercise treatment-induced changes in psychological factors leading to weight loss

Physical activity may affect weight loss largely through psychological pathways associated with eating changes, especially in obese individuals whose caloric expenditure through exercise is typically small. Direct testing of this is, however, lacking. Previously sedentary adults (N?=?114; 77% female; M _age?=?43.3 years), with a minimum body mass index (BMI) of 35?kg/m² (M _BMI?=?42.0?kg/m²), participated in a 24-week treatment of cognitive-behavioural exercise support and nutrition information. A path model based on tenets of social cognitive and self-efficacy theory was constructed. It was expected that improvements in self-efficacy, physical self-concept, body satisfaction and mood associated with the exercise treatment would predict changes in self-regulation and increased physical activity. It was also hypothesised that improvements in self-efficacy and self-regulation for appropriate eating would transfer from these relationships and predict weight loss. After three theoretically viable paths were added based on modification indices, structural equation modelling indicated a good fit with the data, χ ²(16)?=?20.53, p?=?0.20; RMSEA?=?0.05; SRMR?=?0.06; CFI?=?0.97; TLI?=?0.95. Associations of psychological effects linked to exercise programme participation with predictors of appropriate eating and weight loss were found, and may inform theory, research and treatments.
