Do “mudsplashes” induce tactile change blindness?

The phenomenon of change blindness (the surprising inability of people to correctly perceive changes between consecutively presented displays), primarily reported in vision, has recently been shown to occur for positional changes presented in tactile displays as well. Here, we studied people’s ability to detect changes in the number of tactile stimuli in successively presented displays composed of one to three stimuli distributed over the body surface. In Experiment 1, a tactile mask consisting of the simultaneous activation of all seven possible tactile stimulators was sometimes presented between the two to-be-discriminated tactile displays. In Experiment 2, a “mudsplash” paradigm was used, with a brief irrelevant tactile distractor presented at the moment of change of the tactile display. Change blindness was demonstrated in both experiments, thus showing that the failure to detect tactile change is not necessarily related to (1) the physical disruption between consecutive events, (2) the effect of masking covering the location of the change, or (3) the erasure or resetting of the information contained within an internal representation of the tactile display. These results are interpreted in terms of a limitation in the number of spatial locations/events that can be consciously accessed at any one time. This limitation appears to constrain change-detection performance, no matter the sensory modality in which the stimuli are presented.     

Attention and memory in children with brain tumors.

The Rey Auditory Verbal Learning Test was utilized to examine attention, learning, and memory abilities in 42 children with cerebellar (N = 18) and third ventricle tumors (N = 24). Children with cerebellar tumors exhibited significant auditory attentional impairments and displayed adequate encoding and retrieval across subsequent learning and memory trials. In contrast, children with third ventricle tumors exhibited average auditory attentional abilities, but they displayed mild encoding deficits across trials 2-5. Furthermore, the third ventricle group's compromised performance on the delayed recall trial and average performance on the delayed recognition trial is suggestive of underlying retrieval deficits.     

Migration and psychological status of adolescents in Turkey

The aim of this study was to investigate the influence of involuntary migration on an adolescent population that had moved with their families to either one of two culturally different locations in Turkey. One of these groups had moved from a village in Eastern Turkey to a nearby town, while the other had moved a considerable distance to a large city in Western Turkey. Comparison groups included adolescents from both regions who had never migrated. Measures of self-esteem, satisfaction with life, and social support networks were used with 305 adolescents who were between the ages of 12 and 15. Adolescents who had migrated scored lower on self-esteem and life satisfaction, and had fewer people in their social support networks than those who had not. It was also found that those who had migrated tended to be more dependent on peers than family for social support. This was probably the case because school attendance was lower for migrants, particularly for males, and the probability of full time work on the street away from their families was considerably higher.     

Religion and the Paradox of Racial Inequality Attitudes

There appears to be an interesting paradox in American attitudes toward racial inequality: while Americans almost universally see inequality as a social evil, they also consistently oppose government programs to remedy it. This discrepancy appears to result from accounts for the causes of inequality: if inequality is caused by individual failures, rather than structural conditions, then government solutions to racial inequality are unlikely. We examine the role of religion in the formation of attitudes concerning racial inequality for both blacks and whites. Using logistic regression on data from the 1996 General Social Survey, we find that the inclusion of African Americans and multiple religious traditions further complicates the story behind contemporary debates over attitudes pertaining to racial inequality.     

Wrestling with American values: an exploratory investigation of World Wrestling EntertainmentTM as a product‐based subculture

Described as the ‘face of American culture’, World Wrestling Entertainment^TM (WWE) events are broadcast in over 162 countries and draw more than 500 million regular viewers. This paper explores the proposition that the WWE fan base represents a product‐based subculture in American society. Using a value laddering methodology, shared values of WWE fans are exposed and the proposition of core and unique cultural values is supported. Practitioner and theoretical implications of the results are discussed. Copyright © 2004 Henry Stewart Publications.

Music as a Therapeutic Medium for Occupational Engagement: Implications for Occupational Therapy

Music is a meaningful occupation; a summary of current literature and the authors’ experiences regarding health and wellness benefits and potential for music as a therapeutic medium in occupational therapy practice is presented. An interview and a summary of the authors’ experiences illustrate the role for music and its benefits for occupational therapy. These benefits are described through three themes which emerged: (a) music as a means of increasing group cohesion toward common goals, (b) music as a means of increasing socialization, and (c) music as a meaningful occupation can empower individuals to enhance and embrace wellness and recovery.     

Evolutionary Constraints on Human Object Perception

Language and culture endow humans with access to conceptual information that far exceeds any which could be accessed by a non‐human animal. Yet, it is possible that, even without language or specific experiences, non‐human animals represent and infer some aspects of similarity relations between objects in the same way as humans. Here, we show that monkeys’ discrimination sensitivity when identifying images of animals is predicted by established measures of semantic similarity derived from human conceptual judgments. We used metrics from computer vision and computational neuroscience to show that monkeys’ and humans’ performance cannot be explained by low‐level visual similarity alone. The results demonstrate that at least some of the underlying structure of object representations in humans is shared with non‐human primates, at an abstract level that extends beyond low‐level visual similarity. Because the monkeys had no experience with the objects we tested, the results suggest that monkeys and humans share a primitive representation of object similarity that is independent of formal knowledge and cultural experience, and likely derived from common evolutionary constraints on object representation.
