Reading with a filtered fovea: The influence of visual quality at the point of fixation during reading

Reading relies critically on processing text in foveal vision during brief fixational pauses, and high-quality visual input from foveal text is fundamental to theories of reading. However, the quality of visual input from foveal text that is actually functional for reading and the effects of this input on reading performance are unclear. To investigate these issues, a moving, gaze-contingent foveal filtering technique was developed to display areas of text within foveal vision that provided only coarse, medium, or fine scale visual input during each fixational pause during reading. Normal reading times were unaffected when foveal text up to three characters wide at the point of fixation provided any one visual input (coarse, medium, or fine). Wider areas of coarse visual input lengthened reading times, but reading still occurred, and normal reading times were completely unaffected when only medium or fine visual input extended across the entire fovea. Further analyses revealed that each visual input had no effect on the number of fixations made when normal text was read, that adjusting fixation durations helped preserve reading efficiency for different visual inputs, and that each visual input had virtually no effect on normal saccades. These findings indicate that, despite the resolving power of foveal vision and the emphasis placed on high-quality foveal visual input by theories of reading, normal reading functions with similar success using a range of restricted visual inputs from foveal text, even at the point of fixation. Some implications of these findings for theories of reading are discussed.     

Acceptance-Enhanced Behavior Therapy for Trichotillomania in Adolescents

Although several studies have examined the efficacy of Acceptance Enhanced Behavior Therapy (AEBT) for the treatment of trichotillomania (TTM) in adults, data are limited with respect to the treatment of adolescents. Our case series illustrates the use of AEBT for TTM in the treatment of two adolescents. The AEBT protocol (Woods & Twohig, 2008) is a structured treatment manual that was adapted to the individual clients’ needs and clinical progress. Both clients reported clinically significant gains in treatment as determined by at least 2 weeks of abstinence from pulling, and subjective reports of decreased distress and impairment, although one required a booster session due to relapse. AEBT is worth further exploration as a treatment for adolescents with TTM.     

Organizational Citizenship Behavior,Job Attitudes,and the Psychological Contract

Previous research has shown a positive relationship between job satisfaction and various dimensions of organizational citizenship behavior. These studies, however, have focused almost exclusively on civilian sector organizations. While insight gained from these studies is instructive, it remains to be seen if these relationships also exist in the context of military organizations. The relationships between job satisfaction as well as cynicism (as moderated by psychological contracts) with organizational citizenship behavior (OCB) are explored. Data were collected from military officers (n = 151) attending a 10-month professional military education school. As an improvement over other similar studies, control measures were incorporated to address potential confounds associated with self-reported attitudes. Results showed job satisfaction was a strong predictor of OCB, cynicism was negatively related to the altruism dimension of OCB, and the relationship between cynicism and the altruism dimension of organizational citizenship behavior was moderated such that the relationship was stronger when there were high levels of perceived psychological contract support than when there were low levels of support.     

Cognitive Abilities Involved in Insight Problem Solving: An Individual Differences Model

This study investigated individual differences in cognitive abilities that contribute to solving insight problems. A model is proposed describing three types of cognitive ability that contribute independently to insight: convergent thinking, divergent thinking, and breaking frame. The model was tested in a large sample (N = 108) by regressing insight problem solving performance on measures of these three abilities. This analysis demonstrated that all three abilities predicted insight independently. Convergent thinking was further broken down into verbal intelligence and working memory, which also predicted insight independently of each other and of divergent thinking and breaking frame. Finally, when pitted against noninsight problem solving as a predictor in regression, only insight problem solving was uniquely associated with divergent thinking and breaking frame. The model is suggested as a potentially useful taxonomy for the study of ill-defined problems and cognitive abilities.     

On Being Moved by Art: How Reading Fiction Transforms the Self

An experiment tested the hypothesis that art can cause significant changes in the experience of one's own personality traits under laboratory conditions. After completing a set of questionnaires, including the Big-Five Inventory (BFI) and an emotion checklist, the experimental group read the short story The Lady With the Toy Dog by Chekhov, while the control group read a comparison text that had the same content as the story, but was documentary in form. The comparison text was controlled for length, readability, complexity, and interest level. Participants then completed again the BFI and emotion checklist, randomly placed within a larger set of questionnaires. The results show the experimental group experienced significantly greater change in self-reported experience of personality traits than the control group, and that emotion change mediated the effect of art on traits. Further consideration should be given to the role of art in the facilitation of processes of personality growth and maturation.     

Responsible Conduct of Research Training and Trust Between Research Postgraduate Students and Supervisors

The federal regulations of human research were written to permit the use of discretion so that research can fit the circumstances under which it is conducted. For example, the researcher and institutional review board (IRB) could waive or alter some informed consent elements if they deem this the morally and scientifically best way to conduct the research. To do so, however, researchers and IRBs would first have to use mature moral and scientific judgment. They might also have to rely on empirical research to discover the most effective way to act on their moral sense (e.g., to discover how best to approach potential research participants and explain the nature and purpose of the research participation for which they are being recruited, to ensure comprehension and competent decision making). On discovering the most ethical way to proceed, they would then need to look to the federal regulations of human research to discover how to document their decision and justify it within that somewhat flexible regulatory structure. Unfortunately, many IRBs and researchers fail to take these sensible steps to solve ethical problems and proceed immediately to a default requirement of the regulations that places science at odds with the regulations and, ostensibly, with ethics. The following articles in this special issue are about the process of learning to engage in ethical problem solving and using the flexibility permitted by the federal regulations. These articles extricate researchers from the mindset that has gotten them into trouble, and, ideally, provoke them to use mature common sense and moral judgment.     

Projective Drawings in a Cerebellar Disorder Due to Chicken Pox Encephalitis

Projective drawings may be more sensitive to cerebellar disorders than the Rorschach or the geometric designs of the Bender. Drawings of a nine-year-old whose “bad case of chicken pox” was later diagnosed as varicella encephalitis are presented, with suggestions as to why this sensitivity may occur.
