Quiet eye duration,expertise, and task complexity in near and far aiming tasks

. Skilled (n = 12) and less skilled (n = 12) billiards players participated in 2 experiments in which the relationship between quiet eye duration, expertise, and task complexity was examined in a near and a far aiming task. Quiet eye was defined as the final fixation on the target prior to the initiation of movement. In Experiment 1, skilled performers exhibited longer fixations on the target (quiet eye) during the preparation phase of the action than their less skilled counterparts did. Quiet eye duration increased as a function of shot difficulty and was proportionally longer on successful than on unsuccessful shots for both groups of participants. In Experiment 2, participants executed shots under 3 different time-constrained conditions in which quiet eye periods were experimentally manipulated. Shorter quiet eye periods resulted in poorer performance, irrespective of participant skill level. The authors argue that quiet eye duration represents a critical period for movement programming in the aiming response.     

The perception and discrimination of local 3-D surface structure from deforming and disparate boundary contours

In a series of four experiments, we evaluated observers' abilities to perceive and discriminate ordinal depth relationships between separated local surface regions for objects depicted by static, deforming, and disparate boundary contours or silhouettes. Comparisons were also made between judgments made for silhouettes and for objects defined by surface texture, which permits judgment based on conventional static texture gradients, conventional stereopsis, and conventional structure-from-motion. In all the experiments, the observers were able to detect, with relatively high precision, ordinal depth relationships, an aspect of local three-dimensional (3-D) structure, from boundary contours or silhouettes. The results of the experiments clearly demonstrate that the static, disparate, and deforming boundary contours of solid objects are perceptually important optical sources of information about 3-D shape. Other factors that were found to affect performance were the amount of separation between the local surface regions, the proximity or closeness of the regions to the boundary contour itself, and for the conditions with deforming contours, the overall magnitude of the boundary deformation.     

Exercise Dependence: Diagnostic and Therapeutic Issues for Patients in Psychotherapy

Health promotion and exercise is recognized as an important ingredient in health maintenance. Within the diagnostic category of obsessive-compulsive disorders has been the increased recognition by clinicians of a phenomena best described as exercise dependence. Reviewed herein is its definition, theoretical framework and a spectrum of factors often associated with exercise. Realizing that exercise dependence as a clinical entity is not yet recognized in either the International Classification of Disorders (ICD-9) or the Diagnostic and Statistical Manual (DSM-IV-R), proposed criteria for its inclusion are offered. Where a pattern of behavior shows the presence of symptoms consistent with exercise dependence, clinical diagnosis should be made to assure that appropriate treatment might be offered to manage the condition and continue to make exercise an important part of a healthy lifestyle. Diagnostic and therapeutic considerations are offered for the contemporary psychotherapist.     

Sibling Hostility and Externalized Symptoms of Psychological Distress

Sibling verbal and physical abuse has been underrepresented in childhood maltreatment research as a potential contributor to lifetime aggression. This study investigated associations between sibling hostility (physical abuse, threats of violence, heated verbal conflict) and conduct disorder symptoms, trait hostility, and lifetime aggression after control for variance attributable to physical and sexual abuse, exposure to domestic violence, and peer bullying. Over 20% of the respondents from this university sample (N = 1,331) recalled high levels of sibling hostility from the ages of 5 to 16. The frequency of these acts served as a significant predictor in regression models for all of the criterion measures among the women. Relationships between sibling hostility and these externalized symptom indicators were more limited among the men. Acts of sibling hostility as infrequent as once a year were associated in the total sample with higher conduct disorder symptoms, reactive aggression, lifetime acts of physical aggression, and Buss-Perry Aggression Questionnaire subscale scores. These findings suggested that even low frequencies of sibling abuse may have a deleterious impact on temper management. Sibling hostility warrants systematic attention in the childhood maltreatment literature.     

“Let the heavens be glad,and the earth rejoice”: religion and life satisfaction among emerging adults in the United States

Although previous research suggests that religion contributes to greater life satisfaction, there is still disagreement about what aspects of religion predict greater life satisfaction. Despite a growing body of theory and research on emerging adulthood as a life stage that is distinct from adolescence and young adulthood, there has also been limited research on the relationship between religion and life satisfaction among emerging adults. Based on the third wave of the National Study of Youth and Religion, our results suggest that two measures of private religiosity, private devotion and religious efficacy, are significantly related to greater life satisfaction among emerging adults. In contrast, other dimensions of private and public religiosity, such as participation in organised religion, religious salience, otherworldly beliefs, and number of religious friends, are not related to greater life satisfaction. Finally, among emerging adults, being spiritual but not religious is not significantly related to life satisfaction.     

Differentiating corporal punishment from physical abuse in the prediction of lifetime aggression

Corporal punishment and parental physical abuse often co‐occur during upbringing, making it difficult to differentiate their selective impacts on psychological functioning. Associations between corporal punishment and a number of lifetime aggression indicators were examined in this study after efforts to control the potential influence of various forms of co‐occurring maltreatment (parental physical abuse, childhood sexual abuse, sibling abuse, peer bullying, and observed parental violence). College students (N = 1,136) provided retrospective self‐reports regarding their history of aggression and levels of exposure to childhood corporal punishment and maltreatment experiences. Analyses focused on three hypotheses: 1) The odds of experiencing childhood physical abuse would be higher among respondents reporting frequent corporal punishment during upbringing; 2) Corporal punishment scores would predict the criterion aggression indices after control of variance associated with childhood maltreatment; 3) Aggression scores would be higher among respondents classified in the moderate and elevated corporal punishment risk groups. Strong support was found for the first hypothesis since the odds of childhood physical abuse recollections were higher (OR = 65.3) among respondents who experienced frequent (>60 total disciplinary acts) corporal punishment during upbringing. Partial support was found for the second and third hypotheses. Dimensional and categorical corporal punishment scores were associated significantly with half of the criterion measures. These findings support efforts to dissuade reliance on corporal punishment to manage child behavior.

     

A Discussion of “Disorders of Temporality and The Subjective Experience of Time: Unresponsive Objects and the Vacuity of the Future” by Stephen Seligman

In this review of Stephen Seligman’s contribution to the literature on disorders of temporality, the patient’s ordinary and extraordinary experiences of time in the clinical situation, the reviewer provides both theoretical confirmation and clinical illustration in support of the author’s arguments. Infant research, nonlinear dynamic systems theory, and especially a brain-based psychoanalytic perspective taken from the work of Gerald Edelman are introduced to facilitate understanding of memory in general and the second of Seligman’s disorders of temporality in particular. Edelman’s formulation on the biological evolution of consciousness affords a means to comprehend how the phenomenon of dissociation emerges spontaneously in the clinical situation that matches and offers an explanation Seligman’s own understanding.     

Interpersonal Trauma,Posttraumatic Stress Disorder Symptoms,and the Interpersonal Theory of Suicide in Women Seeking Shelter from Intimate Partner Violence

This study examined how trauma exposure and posttraumatic stress disorder symptoms of reexperiencing, avoidance, numbing, dysphoric arousal, and anxious arousal relate to the major components of the interpersonal theory of suicide; namely, thwarted belongingness, perceived burdensomeness, and the acquired capability for suicide. A sample of 137 women seeking shelter from intimate partner violence completed self-report assessments. Symptoms of dysphoric arousal and numbing were uniquely and positively associated with thwarted belongingness. Numbing symptoms were uniquely and positively associated with perceived burdensomeness. Reexperiencing and anxious arousal symptoms were uniquely but negatively associated with the acquired capability for suicide. Interpersonal trauma was also positively associated with acquired capability, but only when examined independently. Posttraumatic stress disorder symptoms of dysphoric arousal and numbing symptoms might complement brief screenings for acute suicide risk and can help inform in-shelter activities as well as postshelter treatment recommendations to decrease suicide risk for shelter-seeking women.     

A Comparison of the Effects of Ethics Training on International and US Students

As scientific and engineering efforts become increasingly global in nature, the need to understand differences in perceptions of research ethics issues across countries and cultures is imperative. However, investigations into the connection between nationality and ethical decision-making in the sciences have largely generated mixed results. In Study 1 of this paper, a measure of biases and compensatory strategies that could influence ethical decisions was administered. Results from this study indicated that graduate students from the United States and international graduate students studying in the US are prone to different biases. Based on these findings, recommendations are made for developing ethics education interventions to target these decision-making biases. In Study 2, we employed an ethics training intervention based on ethical sensemaking and used a well-established measure of ethical decision-making that more fully captures the content of ethical judgment. Similar to Study 1, the results obtained in this study suggest differences do exist between graduate students from the US and international graduate students in ethical decision-making prior to taking the research ethics training. However, similar effects were observed for both groups following the completion of the ethics training intervention.     

A Different Trolley Problem: The Limits of Environmental Justice and the Promise of Complex Moral Assessments for Transportation Infrastructure

Transportation infrastructure tremendously affects the quality of life for urban residents, influences public and mental health, and shapes social relations. Historically, the topic is rich with social and political controversy and the resultant transit systems in the United States cause problems for minority residents and issues for the public. Environmental justice frameworks provide a means to identify and address harms that affect marginalized groups, but environmental justice has limits that cannot account for the mainstream population. To account for this condition, I employ a complex moral assessment measure that provides a way to talk about harms that affect the public.
