Toward an alternative evolutionary theory of religion: looking past computational evolutionary psychology to a wider field of possibilities

Cognitive science of the last half-century has been dominated by the computational theory of mind and its picture of thought as information processing. Taking this picture for granted, the most prominent evolutionary theories of religion of the last fifteen years have sought to understand human religiosity as the product or by-product of universal information processing mechanisms that were adaptive in our ancestral environment. The rigidity of such explanations is at odds with the highly context-sensitive nature of historical studies of religion, and thus contributes to the apparent tug-of-war between scientific and humanistic perspectives. This essay argues that this antagonism stems in part from a deep flaw of computational theory, namely its notion of information as pre-given and context-free. In contrast, non-computational theories that picture mind as an adaptive, interactive process in which information is jointly constructed by organism and environment offer an alternative approach to an evolutionary understanding of human religiosity, one that is compatible with historical studies and amenable to a wide range of inquiries, including some limited kinds of theological inquiry.     

The exponential learning equation as a function of successful trials results in sigmoid performance

While the exponential learning equation, indicating a gradually diminishing improvement, is one of the standard equations to describe learning, a sigmoid behavior with initially increasing then decreasing improvement has also been suggested. Here we show that the sigmoid behavior is mathematically derived from the standard exponential equation when the independent variable of the equation is restricted to the successful trials alone. It is suggested that for tasks promoting success-based learning, performance is better described by the derived sigmoid curve.     

Distinctiveness in flashbulb memory: Comparative analysis of five terrorist attacks

The purpose of the present study was to find out whether a series of terrorist attacks, which share some common features, elicit flashbulb memories (of the personal circumstances in which the person first learned about these events) that are usually elicited by a single, unexpected, surprising, and personally important event. A total of 131 participants answered questions regarding details of five terrorist attacks that had taken place in Israel during the years 1995–1997. In addition, they assessed, for each of the five events, the number of overt rehearsals, and the degrees of emotional intensity, surprise, novelty, personal importance, and distinctiveness. Data analyses showed that most variables that are usually associated with the formation of flashbulb memories were also found in memories of the terrorist attacks that were judged by the participants as being distinctive. Distinctiveness may therefore be considered an important factor in the formation of flashbulb memories.     

Benevolently bowing out: the influence of self-construals and leadership performance on the willful relinquishing of power

Sometimes a group's best interest is served when powerful people relinquish power, but little theory or empirical research has investigated when and by whom power is willingly given-up. Using a simulated, online team competition, two studies demonstrated that people who were dispositionally high in interdependent self-construals were more likely to relinquish their position of leadership within a group when they perceived that their leadership performance on the task was unambiguously poor versus good. However, when given the ability to attribute performance to others rather than the self, leader's level of interdependent self-construal did not significantly influence their decisions to relinquish power. Overall, these findings suggest that factors such as perceived leadership performance, interdependent self-construals, and ability to defer blame all converge when making decisions in regards to how much power should be relinquished.     

Behavioral Skills Training With Teachers: Booster Training for Improved Maintenance

Behavioral skills training (BST) has been employed within many different populations for the reduction of problem behaviors and acquisition of new skills; however, these changes have not always maintained over time. This study evaluated the effects of a booster training for re-establishing the classroom management proficiencies that teachers had acquired previously, but had declined over a 12-month period. The single-subject experimental results showed the booster training to be effective in re-establishing teacher performance of skills as measured by both analogue role-play and in situ postassessments within the classroom. These findings suggest that a booster training utilizing BST may be an important strategy for maintaining skill performance over time.     

The Relationships Among Differing Loss Experiences,Adjustment, Beliefs,and Coping

Abstract

Losses are often equated for conceptual purposes, and it is often assumed that different types of losses result in similar grief reactions and exert similar effects on cognitive structures and coping patterns. This article examines the expectancies, beliefs, coping patterns, and psychological adjustment associated with loss due to death, parental. divorce, or illness and disability in a college student population. Loss groups did not differ from each other or from a no-loss group on cognitive variables, coping, or psychological adjustment. In instances in which associations between the cognitive measures and either coping or adjustment were indicated, the typical pattern was for loss groups to differ from the no-loss condition but not from each other.     

Friendly drug-dealers and terrifying puppies: Affective primacy can attenuate the N400 effect in emotional discourse contexts

Words that are semantically congruous with their preceding discourse context are easier to process than words that are semantically incongruous with their context. This facilitation of semantic processing is reflected by an attenuation of the N400 event-related potential (ERP). We asked whether this was true of emotional words in emotional contexts where discourse congruity was conferred through emotional valence. ERPs were measured as 24 participants read two-sentence scenarios with critical words that varied by emotion (pleasant, unpleasant, or neutral) and congruity (congruous or incongruous). Semantic predictability, constraint, and plausibility were comparable across the neutral and emotional scenarios. As expected, the N400 was smaller to neutral words that were semantically congruous (vs. incongruous) with their neutral discourse context. No such N400 congruity effect was observed on emotional words following emotional discourse contexts. Rather, the amplitude of the N400 was small to all emotional words (pleasant and unpleasant), regardless of whether their emotional valence was congruous with the valence of their emotional discourse context. However, consistent with previous studies, the emotional words produced a larger late positivity than did the neutral words. These data suggest that comprehenders bypassed deep semantic processing of valence-incongruous emotional words within the N400 time window, moving rapidly on to evaluate the words’ motivational significance.
