The Acquisition and Function of Religious Beliefs: A Review and Synthesis of Proximate and Ultimate Perspectives

ABSTRACT

Two main scientific approaches have renewed in the last decade the scientific study of religion: the cognitive and the adaptationist. The former is focused on proximate causes, the latter is looking for ultimate causes of religious beliefs and behaviours. Both approaches are useful and promising. However, in both cases, various important aspects and contexts associated with the origin, acquisition, and transmission of religious beliefs have been neglected. The present paper offers an approach that conjoins both models after reviewing several critical issues, to highlight a distinction between cognitive conditions and structures, on one side; and developments or applications, on the other. As a result greater attention needs to be paid to religious functions and their cultural framework to better understand religion and to explain some current processes, like massive secularization in several areas.     

Positivity bias in employees' self-ratings of performance relative to supervisor ratings: The roles of performance type,performance-approach goal orientation,and perceived influence

As hypothesized, data from two field studies among employees and their supervisors showed that employees are more likely to positively bias their self-ratings relative to supervisor ratings when creative performance rather than inrole performance is being evaluated. In addition, employees' performance-approach goal orientation and perceived influence were found to enhance positivity bias in self-ratings of creative performance. Moreover, performance-approach goal orientation and perceived influence appeared to combine and interact in their effects, such that the impact of perceived influence on positivity bias in self-ratings was larger when performance-approach goal orientation was weaker rather than stronger.     

Exercise type relates to inhibitory and error processing functions in older adults

ABSTRACT

This study investigated the association between exercise type and inhibition of prepotent responses and error detection. Totally, 75 adults (M = 68.88 years) were classified into one of three exercise groups: those who were regular participants in open- or closed-skill forms of exercise, and those who exercised only irregularly. The participants completed a Stroop and task-switching tasks with event-related brain potentials (ERPs) recorded. The results revealed that regular exercisers displayed faster reaction times (RTs) in the Stroop task compared with irregular exercisers. The open-skill exercisers exhibited smaller N200 and larger P300a amplitudes in the Stroop task compared with irregular exercisers. Furthermore, the open-skill exercisers showed a tendency of shorter error-related negativity latencies at the task-witching test. The findings suggest that older adults may gain extra cognitive benefits in areas such as inhibition functioning and error processing from participating in open-skill forms of physical exercises.     

Saccadic eye movements as indicators of cognitive function in older adults

Older adults appear to have greater difficulty ignoring distractions during day-to-day activities than younger adults. To assess these effects of age, the ability of adults aged between 50 and 80 years to ignore distracting stimuli was measured using the antisaccade and oculomotor capture tasks. In the antisaccade task, observers are instructed to look away from a visual cue, whereas in the oculomotor capture task, observers are instructed to look toward a colored singleton in the presence of a concurrent onset distractor. Index scores of the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) were compared with capture errors, and with prosaccade errors on the antisaccade task. A higher percentage of capture errors were made on the oculomotor capture tasks by the older members of the cohort compared to the younger members. There was a weak relationship between the attention index and capture errors, but the visuospatial/constructional index was the strongest predictor of prosaccade error rate in the antisaccade task. The saccade reaction times (SRTs) of correct initial saccades in the oculomotor capture task were poorly correlated with age, and with the neurospsychological tests, but prosaccade SRTs in both tasks moderately correlated with antisaccade error rate. These results were interpreted in terms of a competitive integration (or race) model. Any variable that reduces the strength of the top-down neural signal to produce a voluntary saccade, or that increases saccade speed, will enhance the likelihood that a reflexive saccade to a stimulus with an abrupt onset will occur.     

Episodic future thinking: Linking neuropsychological performance with episodic detail in young and old adults

Episodic future thinking (EFT) has been linked with our ability to remember past events. However, its specific neurocognitive subprocesses have remained elusive. In Experiment 1, a study of healthy older adults was conducted to investigate the candidate subprocesses of EFT. Participants completed a standard EFT cue word task, two memory measures (Verbal Paired Associates I, Source Memory), and two measures of executive function (Trail Making Test, Tower Test). In Experiment 2, healthy young adults also completed an EFT task and neuropsychological measures. The link between neurocognitive measures and five characteristics of EFT was investigated. Specifically, it was found that Source Memory and Trail Making Test performance predicted the episodic specificity of future events in older but not younger adults. Replicating previous findings, older adults produced future events with greater semantic but fewer episodic details than did young adults. These results extend the data and emphasize the importance of the multiple subprocesses underlying EFT.     

The impact of working memory load on task execution and online plan adjustment during multitasking in a virtual environment

Three experiments investigated the impact of working memory load on online plan adjustment during a test of multitasking in young, nonexpert, adult participants. Multitasking was assessed using the Edinburgh Virtual Errands Test (EVET). Participants were asked to memorize either good or poor plans for performing multiple errands and were assessed both on task completion and on the extent to which they modified their plans during EVET performance. EVET was performed twice, with and without a secondary task loading a component of working memory. In Experiment 1, articulatory suppression was used to load the phonological loop. In Experiment 2, oral random generation was used to load executive functions. In Experiment 3, spatial working memory was loaded with an auditory spatial localization task. EVET performance for both good- and poor-planning groups was disrupted by random generation and sound localization, but not by articulatory suppression. Additionally, people given a poor plan were able to overcome this initial disadvantage by modifying their plans online. It was concluded that, in addition to executive functions, multiple errands performance draws heavily on spatial, but not verbal, working memory resources but can be successfully completed on the basis of modifying plans online, despite a secondary task load.     

Influence analysis of structural equation models with polytomous variables

The estimation of model parameters in structural equation models with polytomous variables can be handled by several computationally efficient procedures. However, sensitivity or influence analysis of the model is not well studied. We demonstrate that the existing influence analysis methods for contingency tables or for normal theory structural equation models cannot be applied directly to structural equation models with polytomous variables; and we develop appropriate procedures based on the local influence approach of Cook (1986). The proposed procedures are computationally efficient, the necessary bits of the proposed diagnostic measures are readily available following an usual fit of the model. We consider the influence of an individual cell frequency with respect to three cases: when all parameters in an unstructured model are of interest, when the unstructured polychoric correlations are of interest, and when the structural parameters are of interest. We also consider the sensitivity of the parameters estimates. Two examples based on real data are presented for illustration.The work described in this paper was partially supported by a Chinese University of Hong Kong Postdoctoral Fellows Scheme and a grant from the Research Grants Council of the Hong Kong Special Administrative Region, China (RGC Ref.

Bentler and M.D. Newcomb for providing the data set, Michael Leung for his assistance, and the Editor and the referees for some very valuable comments.     

Certainty and Uncertainty: The Two Faces of the Hindsight Bias

“Hindsight Bias” is a person's tendency, after learning about the actual outcome of a situation or the correct answer to a question, to distort a previous judgment in the direction of this new information. In the literature, hindsight bias has been mostly discussed as an inevitable result of a “judgment under uncertainty.” We think that the hindsight bias is due to memorial as well as inferential processes: Whereas certainty about the recollection is memorial and concerns the recollective experience, certainty at the time of the judgment is inferential and concerns the individual's metaknowledge (“I know that I knew that”). In two experiments participants' feelings of certainty were measured indirectly (Koriat & Goldsmith, 1996) by giving participants the option of leaving those questions unanswered about which they felt uncertain. This free-report option was offered to half of the participants in the first estimate phase (concerning time of judgment) and to the second half in the memory phase (concerning the recollective experience). At the end of the session, participants were presented again with the questions they had skipped and were now required to answer them. This procedure allowed us to compare the amount of hindsight bias for the skipped, uncertain items to the spontaneously answered, certain ones. Both experiments demonstrated that the hindsight bias is a result of the interaction of both uncertainty and certainty.
