Event perception as a control process for visual awareness

ABSTRACT

We present evidence demonstrating that the structure of everyday events guides attention to and representation of visual properties. Incidental change detection increases dramatically at the boundaries between events, whereas individuals are largely unaware of the sequence of actions within a single event. Observers demonstrate a limited capacity for representing events, and inducing cognitive load by presenting two simultaneous events decreases detection of sequence errors. These studies support emerging evidence that the event perception network operates as a control process that guides attention and awareness in real-world settings.     

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.     

RESILIENCE,AGENCY, AND EVERYDAY LOJONG IN THE TIBETAN DIASPORA

ABSTRACT

Despite exposure to political violence, many Tibetans in the diaspora avoid framing past experience in terms of trauma. Instead, they deploy shared cultural understandings often infused with Buddhist doctrine, to reframe loss, violence and displacement. Drawing on 14 months of ethnographic research in Dharamsala, India conducted in the Tibetan language, this article investigates how Tibetans utilise everyday cultural wisdom framed by lojong (mind-training) teachings to cope with adversity. Here, compassion practices serve to orient members of the diaspora towards recovery even, and perhaps, especially, when they are struggling. In this article, I argue that this cultural form of resilience is better conceived of as a practice of agency than a mental health practice, despite a global interest in adapting meditation and mindfulness for use in clinical settings. This study also challenges theory on structural violence and social suffering, which tends to overemphasise victimhood, bypassing the ordinary (and extraordinary) ways that people find agency.     

Editorial

Abstract

After outlining its geographical horizons, this article goes on to survey the history of Islam, in Europe and the different profiles of the Muslim communities today in western Europe, the USA and the Balkans. It suggests that there are usually four phases in the development of these communities. The three main Western approaches to managing diversity are outlined, alongside the three most common models for the relationship between religion and the state. The politics of identity is discussed, addressing the question, ‘How can religious diversity be reconciled with shared citizenship?’, along with the crisis of leadership among Muslims in the West and the radicalisation of some Muslims. Muslim attitudes towards Christianity are described, as are church responses at both national and international level. Finally two further questions are addressed: ‘Can the churches act as an antidote to religious nationalism?’ and ‘Can Christians and Muslims together shape civic space for the common good?’     

Strength of a Secondary Reinforcement as a Function of the Quality of Food Reward

Thirty-two children were presented 18 stories containing either a good, neutral, or negative act which was followed by either a reward or punishment. It was predicted that Ss' responses would be influenced by the sanctions. It was also predicted that the type of story (good, neutral, or bad) would influence the extent to which a child judged the act independent of the effects of the sanction (reward or punishment).

These predictions were supported. Ss made more positive responses to acts followed by reward than to those followed by punishment. However, an examination of a Content × Sanction interaction found the sanction of reward relatively ineffective for the stones with negative content.     

The Relationship Between Leadership Behaviors and Group Cohesion in Team Sports

The relationship between leadership behaviors and team cohesion among baseball and softball players at two school levels was analyzed in relation to predictions based on Chelladurai and Carron's (1978) Multidimensional Model of Leadership (MML). Athletes (n = 307) completed the perceived and preferred versions of the Leadership Scale for Sports (LSS) and the Group Environment Questionnaire (GEQ). Athletes' coaches (n = 23) completed the self-perceived version of the LSS. Task and social cohesion were assessed in relation to the scales of the three individual versions of the LSS and in relation to two types of discrepancy scores: value and perceptual. Although the concept of discrepancy is prominent in MML theory, the perceptual discrepancy score represents an innovation. Results indicated that, in general, team cohesion was most strongly related to the perceived LSS version and the perceptual discrepancy scores.     

Oral Pessimism and Depressive Symptoms

I examined the relation of oral optimistic and oral pessimistic personality traits to depressive symptoms to assess the psychoanalytic claim that fixation at the early phase of the oral stage of psychosexual development is related to depression. College students (N = 140) were administered the Oral Optimism Questionnaire (OOQ; Kline, 1978) and Oral Pessimism Questionnaire (OPQ; Kline, 1978) and the Beck Depression Inventory (BDI; Beck, Ward, Mendelsohn, Mock, & Erbaugh, 1961). Oral pessimism and levels of depressive symptoms were positively correlated, and a subsample of subjects with clinical levels of depressive symptoms also scored significantly higher on the Oral Pessimism Questionnaire than the rest of the sample. For the whole sample, 10 BDI items correlated significantly with the OPQ scores, and 5 OPQ items correlated significantly with the total BDI scores. The psychoanalytic claim relating fixation at the oral pessimism stage to depressive symptoms was supported.     

Lesion analysis of the brain areas involved in language comprehension

The cortical regions of the brain traditionally associated with the comprehension of language are Wernicke's area and Broca's area. However, recent evidence suggests that other brain regions might also be involved in this complex process. This paper describes the opportunity to evaluate a large number of brain-injured patients to determine which lesioned brain areas might affect language comprehension. Sixty-four chronic left hemisphere stroke patients were evaluated on 11 subtests of the Curtiss-Yamada Comprehensive Language Evaluation - Receptive (CYCLE-R; Curtiss, S., & Yamada, J. (1988). Curtiss-Yamada Comprehensive Language Evaluation. Unpublished test, UCLA). Eight right hemisphere stroke patients and 15 neurologically normal older controls also participated. Patients were required to select a single line drawing from an array of three or four choices that best depicted the content of an auditorily-presented sentence. Patients' lesions obtained from structural neuroimaging were reconstructed onto templates and entered into a voxel-based lesion-symptom mapping (VLSM; Bates, E., Wilson, S., Saygin, A. P., Dick, F., Sereno, M., Knight, R. T., & Dronkers, N. F. (2003). Voxel-based lesion-symptom mapping. Nature Neuroscience, 6(5), 448-450.) analysis along with the behavioral data. VLSM is a brain-behavior mapping technique that evaluates the relationships between areas of injury and behavioral performance in all patients on a voxel-by-voxel basis, similar to the analysis of functional neuroimaging data. Results indicated that lesions to five left hemisphere brain regions affected performance on the CYCLE-R, including the posterior middle temporal gyrus and underlying white matter, the anterior superior temporal gyrus, the superior temporal sulcus and angular gyrus, mid-frontal cortex in Brodmann's area 46, and Brodmann's area 47 of the inferior frontal gyrus. Lesions to Broca's and Wernicke's areas were not found to significantly alter language comprehension on this particular measure. Further analysis suggested that the middle temporal gyrus may be more important for comprehension at the word level, while the other regions may play a greater role at the level of the sentence. These results are consistent with those seen in recent functional neuroimaging studies and offer complementary data in the effort to understand the brain areas underlying language comprehension.
