The insistence of vision: Why do people look at a salient stimulus when it signals target absence?

Researchers and practitioners across many fields would benefit from the ability to predict human search time in complex visual displays. However, a missing element in our ability to predict search time is our ability to quantify the exogenous attraction of visual objects in terms of their impact on search time. The current work represents an initial step in this direction. We present two experiments using a quadrant search task to investigate how exogenous and endogenous factors influence human visual search. In Experiment 1, we measure the oculomotor capture—or the tendency of a stimulus to elicit a saccade—of a salient quadrant under conditions in which the salient quadrant does not predict target location. Despite the irrelevance of quadrant salience, we find that subjects persist in making saccades towards the salient quadrant at above-chance levels. We then present a Bayesian-based ideal performer model that predicts search time and oculomotor capture when the salient quadrant never contains the search target. Experiment 2 tested the predictions of the ideal performer model and revealed human performance to be in close correspondence with the model. We conclude that, in our speeded search task, the influence of an exogenous attractor on saccades can be quantified in terms of search time costs and, when these costs are considered, both search time and search behaviour reflect a boundedly optimal adaptation to the cost structure of the environment.     

Differential central resource demands of memory scanning and visual search: The role of consistent and varied mapping

In this paper we compare the effect of mapping on the central resource requirements of two search processes. With consistent mapping of items to the role of either target or distractor, search becomes very efficient; with varied mapping (each item serves as both a target and a distractor in the same experiment), search is less efficient. One interpretation of this effect of manipulating the consistency of mapping is that search under varied mapping requires limited capacity central resources but the requirement for these resources is reduced with consistent mapping. We tested this interpretation by varying the consistency of mapping in memory scanning (Experiments 1 and 2) and in visual search (Experiments 3 and 4) as the second of two tasks in the psychological refractory period (PRP) paradigm. Responses were location based, rather than present/absent judgements, and a target was present on every trial. The results indicated that there was less of a requirement for central resources with consistent mapping than with varied mapping in both memory scanning and in visual search; however, the effect of the mapping manipulation on central resource requirements was different for memory scanning than for visual search. Memory scanning was not done in parallel with a resource-demanding stage of a second task under varied mapping, but was done in parallel with this stage under consistent mapping. Part of visual search under both types of mapping was done in parallel with a resource-demanding stage of a second task and part was not; consistent mapping reduced the duration of the stage of processing that could not be carried out in parallel. We conclude that under consistent mapping, switching among items in memory becomes less controlled and therefore has less of a requirement for central resources than under varied mapping. In visual search, however, consistent mapping improves performance by facilitating the comparison of the target item to items in the search array.     

European developments

The British National Health Service is 50 years old. The provision of many services has changed considerably through this time in ways that reflect shifts in organization and philosophy. The provision of psychotherapy has been particularly sensitive to these changes in ways that have made it more widely available but also shaped its content. As the pace of change continues to accelerate, some implications of the most recent shifts in philosophy for clinical practice are considered.     

Religious experience,religious orientation and schizotypy

The present study examined the relationship between religious orientation and schizotypy, with the prediction that intrinsic religiosity would be negatively associated with schizotypy, and religious experience and extrinsic religiosity would be positively associated with schizotypy. A total of 308 UK adults (132 men; 176 women) completed measures of religious experience, intrinsic orientation towards religion, extrinsic orientation towards religion, schizotypal personality traits and borderline personality. Though the present findings also suggest that the significant relationships between religiosity and schizotypy traits are fragmented, particularly by sex, the findings are consistent with theory that an intrinsic orientation towards religion is associated with lower levels of schizotypy, and religious experience and an extrinsic orientation towards religion is associated with higher levels of schizotypy.     

When 2–3% really matters: The (un)importance of religiosity in psychotherapy

Previous research suggests that clients’ religious beliefs are commonly excluded from therapeutic practice. Often, this exclusion is attributed to practitioners’ lack of knowledge or appropriate skills. Such analyses, however, have little regard for the interactional aspects of the therapist/client encounter. Drawing upon work within discursive social psychology, we argue that the exclusion of religious beliefs does not reflect therapists’ lack of knowledge or awareness but can more usefully be seen as the discursive accomplishment of marginalizing clients’ beliefs. Six practising psychotherapists were interviewed about religious beliefs within the therapeutic process. Participants construct religious beliefs as important but relevant only to restricted categories of clients. They rework religious beliefs as compatible with accepted practice, or construct particular groups of clients as incompatible with the process. Training and other requirements are reformulated in terms of spiritual beliefs rather than religious beliefs. These constructions display awareness of religious beliefs while marginalizing their relevance in practice. Inclusion of clients’ religious beliefs to best effect will require more psychotherapy to engage more constructively with religion than it does at present.     

Knowing What You Cannot Recognise: Further Evidence for Intact Metacognition in Alzheimer's Disease

Previous research has examined whether Alzheimer's disease (AD) patients can proficiently monitor their memory processing. In the present study we extended the scope of this research to consider confidence in recognition in an episodic memory task, using a forced-choice recognition paradigm to avoid floor effects. AD patients and age-matched controls studied 32 words, followed immediately by a recognition test requiring participants to select the target from pairs of items. Participants rated confidence in their choice on a 3-point scale. Despite significantly poorer memory performance and less confidence overall, gamma correlations indicated that the AD group accurately assigned confidence judgements to their responses. This adds support to the claim that metacognitive monitoring remains intact in AD.     

The impact of religious behaviours on the health and well-being of emerging adults

Emerging adulthood is a life stage in which the frequency of religious behaviours often wanes while the risk of mental illness, substance abuse, and risky sexual behaviour increases. The current study explores the role that religious behaviours might play in mitigating these risks among college-attending emerging adults. Survey data were collected on religious service attendance, prayer and meditation, substance use, sexual activity, and life satisfaction. Results revealed a significant effect for religious service attendance on substance use and sexual behaviour and for the frequency of prayer/meditation on life satisfaction, marijuana use, and sexual intercourse. Group comparisons revealed that emerging adults who participated in religious activities reported lower rates of substance use, less sexual behaviour, and greater satisfaction with life. Limitations and suggestions for future research are discussed.     

The Coping Strategies Questionnaire – Swedish Version: Evidence of Reliability and Validity in Patients with Fibromyalgia

Abstract

The aim of this study was to evaluate the reliability and validity of a Swedish version of the Coping Strategies Questionnaire in patients with fibromyalgia. A total of 275 patients from 4 sites in Sweden filled out the questionnaire and other health status and quality of life instruments at the beginning of treatment programs. A total of 28 subjects at 1 site served as wait-listed controls for 12 weeks. Cronbach's Alpha for the subscales ranged from 0.3 3 to 0.86. Coping Strategies Questionnaire subscales correlated significantly with other scales. The treated group had significant positive changes on several Coping Strategies Questionnaire subscales. Principal components analysis found a 3-factor solution consisting of cognitive coping/suppression, pain control/rational thinking and behavioral activity. Analysis by item replicated 4 of the 8 subscales. A further principal components analysis using 27 items replicated an earlier 6-factor solution. The Swedish version of the Coping Strategies Questionnaire has subscales that are reliable, valid and sensitive to change in patients with fibromyalgia.     

Necessity of origins and multi-origin art

The Necessity of Origins is the thesis that, necessarily, if a material object wholly originates from some particular material, then it could not have wholly originated from any significantly non-overlapping material. Several philosophers have argued for this thesis using as a premise a principle that we call ‘Single Origin Necessity’. However, we argue that Single Origin Necessity is false. So any arguments for The Necessity of Origins that rely on Single Origin Necessity are unsound. We also argue that the Necessity of Origins itself is false. Our arguments rely on a thesis in the ontology of art that we find plausible: Multi-Work Materialism. It is the thesis that works of art that have multiple concrete manifestations are co-located with those manifestations.
