Upper-left gaze bias reveals competing search strategies in a reverse Stroop task

Three experiments with a total of 87 human observers revealed an upper-left spatial bias in the initial movement of gaze during visual search. The bias was present whether or not the explicit control of gaze was required for the task. This bias may be part of a search strategy that competed with the fixed-gaze parallel search strategy hypothesized by Durgin [Durgin, F. H. (2003). Translation and competition among internal representations in a reverse Stroop effect. Perception &Psychophysics, 65, 367-378.] for this task. When the spatial probabilities of the search target were manipulated either in accord with or in opposition to the existing upper-left bias, two orthogonal factors of interference in the latency data were differentially affected. The two factors corresponded to two different forms of representation and search. Target probabilities consistent with the gaze bias encouraged opportunistic serial search (including gaze shifts), while symmetrically opposing target probabilities produced latency patterns more consistent with parallel search based on a sensory code.     

Parenting Behavior and Cognitions in a Community Sample of Mothers with and without Symptoms of Attention-deficit/Hyperactivity Disorder

Although attention-deficit/hyperactivity disorder (ADHD) in adults has recently emerged as an important area of research, little attention has been given to the family functioning of women with ADHD, particularly in their role as mothers. We examined parenting self-esteem, locus of control, and disciplinary styles in a community sample of mothers with varying levels of ADHD symptoms. Women with high levels of ADHD symptoms reported more occupational and psychiatric problems than women with lower levels of ADHD symptoms. They also reported lower parenting self-esteem, a more external parenting locus of control, and less effective disciplinary styles. The findings suggest that women with ADHD symptoms may face a number of difficulties within the parenting domain.

Selective Exposure in the Internet Age: The Interaction between Anxiety and Information Utility

The rise of the Internet forces scholars to reevaluate the frequency and nature of political information seeking in the contemporary period. The functionality of the Internet makes passive exposure more difficult, and selective information seeking easier, than in the past. However, people may also use the Internet in a new and directed way—to arm themselves with information to express and defend their views either online or in the real world. The central question we explore in this paper is what explains balanced versus biased information seeking in the era of the Internet? We combine insights from Sears and Freedman (1967 ) with newer work on emotion to predict motivated selectivity: focusing specifically on the interaction between anxiety and information utility. Our central theoretical claim is that anxiety does not simply boost any information seeking; it triggers information seeking that is useful for addressing the problem at hand. Anxiety alone, therefore, does not guarantee a balanced information search. When counterattitudinal information is useful for some reason—for example, to defend their own opinions to others who may disagree—anxious citizens should seek it out. As a consequence, these subjects should learn more specific information about where each candidate stands on the issues. In an experiment we find support for these hypotheses. We conclude that while today's flexible Internet environment may permit selectivity, balanced seeking should still occur under a fairly common set of circumstances.     

Behavioral and physiological correlates of aggressive dominance in male brown lemmings (Lemmus sibiricus)

Naive male brown lemmings were paired with the same opponent for 10 min/day for 11 consecutive days. Males of a control group were placed in an empty arena for the same period. There was no decrement in the incidence of attack and chase by dominant males in pairs showing stable dominant-subordinate relations. Subsequently, seminal vesicles of dominant animals were heavier than those of subordinate, control and “no rank” (pairs in which no clear-cut dominance relations were established) animals. Dominant animals also had greater mean testis weights and higher plasma testosterone levels than subordinates. Adrenal weights did not differ significantly between the various groups. Among dominant males there were significant positive correlations between plasma testosterone levels, testis and seminal vesicle weights, and attack and chase scores. These results suggest that many of the physiological correlates of dominance status reported in previous studies in which subjects were group housed are also observed when contact between naive individuals is limited to brief encounters.     

Promoting positive body image among university students: A collaborative pilot study

The purpose of the present study was to pilot a prevention program designed to promote positive body image among university students. Thirty-seven undergraduate students from three Canadian universities were recruited to participate in the study. They were selected from a pool of students enrolled in a peer health education program facilitated by the university-based health promotion staff. Borrowing from the tenets of the non-specific vulnerability stressor model and the disease-specific social cognitive theory, the intervention focused on media literacy, self-esteem enhancement strategies, stress management skills and ways to recognize healthy versus unhealthy relationships. Separate ANOVAs revealed that participants reported significant improvements in body satisfaction and reductions in the internalization of media stereotypes between the baseline and post-program period. The program received a favorable response from the participating students, who appreciated the face-to-face format of the intervention, and from the university staff who expressed interest in embedding the strategies into their routine peer mentoring training activities. Limitations of the study and suggestions for future research are discussed.     

A role for clinical psychology in health care and policy concerning the physical environment

Some persons adversely react to specific environments, while others are impervious or actually thrive. Medical attention often overlooks such sensitivities to the physical environment. Such sensitivities, including phobias and seasonal affectivity, fall within clinical psychology's purview. A theoretical/clinical approach called the Synchronous Systems Model, which defines and uses individual differences in people and in settings, could serve medical health care and policy. When specific people are matched appropriately with specific treatments within the most propitious settings, cost effectiveness and medical efficacy rise. Such documented accountability could make clinical psychologists central to triage of medical services as well as health care policy in these days of the shrinking health care dollar. The Synchronous Systems Model provides theory, supportive data, and clinical assessment devices to strengthen clinical psychology's role in medical settings.     

A meta‐analytic review of tipping compensation practices: An agency theory perspective

Tipping represents a form of compensation valued at over $50 billion a year in the United States alone. Tipping can be used as an incentive mechanism to reduce a principal–agent problem. An agency problem occurs when the interests of a principal and agent are misaligned, and it is challenging for the principal to monitor or control the activities of the agent. However, past research has been limited in the investigation of the extent to which tipping is effective at addressing this problem. Following an examination of 74 independent studies with 12,271 individuals, meta‐analytic results indicate that there is a small, positive relation between service quality and percentage of a bill tipped ( = .15 without outliers). Yet, in support of the idea behind tipping, relative weights analyses illustrate that service quality was a stronger predictor of percentage of the bill tipped than food quality, frequency of patronage, and dining party size. Evidence also suggests that racial minority servers tend to be tipped less than White servers (Cohen's d = .17), and women tend to be tipped more than men (Cohen's d = .15). Still, given the magnitude of the effect, one might question if tipping is an effective compensation practice to reduce the principal–agent problem. We discuss theoretical and practical implications for future research.
