Sunk Cost and Commitment to Dates Arranged Online

The influence of prior, irretrievable, investment (sunk cost) on commitment to a date arranged online was investigated. Participants were recruited from an undergraduate population. There were 145 participants (86 female) with a mean age of 19.42 years. Participants took part in a computer simulation of the process of arranging a date online. Participants invested one of five amounts of sunk cost into this process. Participants were then presented with the choice of attending the date arranged online or attending a (superior) blind date. Participants chose how much time that they wanted to commit to the (inferior) date arranged online. Results revealed a significant sunk cost effect (p = 0.003). The implications of the sunk cost effect having an influence over human relationships are discussed.     

Rebuilding from the vacuum: A qualitative study of people with a recent history of incarceration

Thirty-four adults recently released from incarceration and living in transitional homes were interviewed in this qualitative study. An open-ended approach to interviewing was used to allow participants’ main concerns to emerge. Participants were primarily focused on rebuilding relationships to achieve stability post-incarceration. Participants who rebuilt stable relationships were able to work on internal goals (e.g., sobriety). Participants who did not rebuild stable relationships returned to existing social networks of unstable connections characterized by drug addiction, abuse, or criminal activity.     

Medical Resource Allocation as a Function of Selected Patient Characteristics

This study assessed how changes in the characteristics of parental status, intelligence level, and mental health of hypothetical patients suffering from a kidney disease altered participants' decisions about allocating access to a life-supporting artificial-kidney machine. Participants were given a list of hypothetical prospective patients who were described as having a kidney disease, yet varied with respect to the three aforementioned characteristics. Participants rank-ordered patients on the basis of priority for treatment. Participants clearly favored hypothetical patients who (a) had children, (b) were of high intelligence, and (c) were mentally healthy.     

AN EXPERIMENTAL COMPARISON OF THREE DIFFERENT SCHEDULES OF REINFORCEMENT OF DRUG ABSTINENCE USING CIGARETTE SMOKING AS AN EXEMPLAR

The efficacy of three different schedules of reinforcement for promoting and sustaining drug abstinence was compared in this study. Cigarette smoking was studied as an exemplar of stimulant drug self-administration. Sixty cigarette smokers were assigned to one of three groups (progressive rate of reinforcement, fixed rate of reinforcement, and yoked control). Participants in all three groups were asked to refrain from smoking for 1 week. Participants in the progressive and fixed groups achieved greater mean levels of abstinence than those in the control group. Participants in the progressive group were significantly less likely to resume smoking when they became abstinent than participants in the other groups.     

Memory for target height is scaled to observer height

According to the embodied approach to visual perception, individuals scale the environment to their bodies. This approach highlights the central role of the body for immediate, situated action. The present experiments addressed whether body scaling—specifically, eye-height scaling—occurs in memory when action is not immediate. Participants viewed standard targets that were either the same height as, taller than, or shorter than themselves. Participants then viewed a comparison target and judged whether the comparison was taller or shorter than the standard target. Participants were most accurate when the standard target height matched their own heights, taking into account postural changes. Participants were biased to underestimate standard target height, in general, and to push standard target height away from their own heights. These results are consistent with the literature on eye-height scaling in visual perception and suggest that body scaling is not only a useful metric for perception and action, but is also preserved in memory.     

The Effects of Media Bias

The current research investigated whether bias exists in newspapers that are considered liberal or conservative, and whether this bias influences public opinion of events. Participants were college students ( N  = 67) who were enrolled in a 4-year university ( n  = 33) or a community college ( n  = 34). Participants were shown photographs and short articles relating to a presidential debate between President George W. Bush and Senator John Kerry. Participants completed questionnaires relating to their opinions of the candidates. Results showed statistical significance within groups before and after exposure to the newspaper clippings.     

An Attitude Functions Approach to Increasing Organ‐Donation Participation1

This research tests a tenet of attitude function theory–the motivational matching hypothesis–by using a functional approach to increase organ donation. Pilot studies validated experimental manipulations and persuasive messages. An experiment tested the hypothesis that persuasive messages that match an aroused function would be more effective than messages that do not match a manipulated function. Participants were exposed to situational manipulations designed to arouse or make salient value‐expressive or knowledge needs, then read an organ‐donation message designed to meet one of these needs. Participants’ organ‐donation attitudes and behaviors were assessed. Participants presented with matching messages were most persuaded and took more action to become donors. Those who experienced stronger motivational arousal exhibited the most change.     

Local and global reference frames for environmental spaces

Two experiments examined how locations in environmental spaces, which cannot be overseen from one location, are represented in memory: by global reference frames, multiple local reference frames, or orientation-free representations. After learning an immersive virtual environment by repeatedly walking a closed multisegment route, participants pointed to seven previously learned targets from different locations. Contrary to many conceptions of survey knowledge, local reference frames played an important role: Participants performed better when their body or pointing targets were aligned with the local reference frame (corridor). Moreover, most participants turned their head to align it with local reference frames. However, indications for global reference frames were also found: Participants performed better when their body or current corridor was parallel/orthogonal to a global reference frame instead of oblique. Participants showing this pattern performed comparatively better. We conclude that survey tasks can be solved based on interconnected local reference frames. Participants who pointed more accurately or quickly additionally used global reference frames.     

Control and Anticipation of Social Interruptions: Reduced Stress and Improved Task Performance1

Social interruptions are frequent occurrences that often have distressing consequences for employees, yet little research has gauged their effect on individuals. Participants were exposed to 2 social interruptions as they engaged in a computer task with an accepted performance goal. Participants who were able to anticipate social interruptions performed significantly better than did those who could not anticipate them. Participants who had the opportunity to prevent interruptions reported significantly less stress than those who did not have this opportunity. This reduction in stress resulted even when participants did not take advantage of this opportunity. Implications for job performance and job satisfaction are discussed. Organizational strategies for how leaders can help employees manage social interruptions are suggested.     

Why are some people with neurological illness more resilient than others?

The current qualitative study was designed to evaluate the coping strategies of people living with a chronic progressive neurological illness and their carers. The neurological illnesses were Huntington's disease, motor neurone disease, multiple sclerosis and Parkinson's disease. Participants included 15 people who showed high levels of adjustment and 15 who showed low levels of adjustment. Participants were selected from an earlier study, to ensure that they satisfied the inclusion criteria for the current study. Interviews were completed to determine the strategies used to cope with the demands of the illness. Participants who demonstrated good adjustment were more likely to draw on social support to provide them with the resources to deal with the illness. In contrast, those who evidenced poor adjustment were more likely to draw on external supports to complete tasks for them. The implications of these findings for people with chronic neurological illnesses and their families are discussed.     

Natural scene stimuli and lapses of sustained attention

We conducted two experiments using naturalistic scene stimuli to test the resource theory and mindlessness theory of sustained attention. In experiment 1, 28 participants completed a traditional formatted vigilance task consisting of non-repeating forest or urban picture stimuli as target stimuli. Participants filled out pre- and post-task assessments of arousal and conscious thoughts. There was still a vigilance decrement, despite non-repetitive, natural target stimuli. Participants found the task demanding and were actively engaged in the task. In experiment 2, 25 participants completed a Sustained Attention to Response Task (SART) using the stimuli from experiment 1. Participants performed significantly worse on this SART than either brain injury patients or controls performing equivalent numeric stimuli SARTs have in previous studies. Participants thought the task was demanding and they were actively engaged with the task. Overall, the results of both studies support a resource theory of sustained attention lapses, not a mindlessness theory.     

SEXUAL HARASSMENT ON CAMPUS

Attitudes about sexual harassment were assessed in a group of 224 undergraduate students. Participants responded to scenarios in which a male professor made inappropriate sexual advances to a female student. Participants then completed rating scales and questions concerning attributions of blame for harassment, educational and emotional effects, and strategies for coping with harassment. The students were divided into high and low groups on the basis of their scores on the Performance Self-Esteem Scale (PSES) and Attitudes toward Women Scale (AWS). The subject groups most tolerant of harassment and least aware of potential harm to its victims were high self-esteem women with traditional sex-role attitudes. Participants also provided information as to their own harassment experiences. Women's reported reactions to actual harassment were consistent with their responses to scenarios. Results are discussed in the context of prevailing sex-role standards.     

Social support from a friend,perceived support,and social problem solving

This research combined experimental and correlational methods to investigate the effects of social support on social problem-solving effectiveness and perceived stress. During a wait period, college students were given the opportunity to work on practice items from a mildly stressful social problem-solving task, either alone or in the company of a close friend. Participants and friends were allowed to talk about the practice items but were not required to do so, and supportive transactions were tape recorded and content analyzed. All students then completed social problem-solving and perceived stress items alone. Participants who waited with friends did not show superior problem-solving effectiveness unless companions provided particular supportive behaviors. Participants with high perceived support scores rated the experiment as less stressful than those with low scores, but perceived support was not related to companions' actual supportive behaviors. The results were discussed in terms of implications for understanding the mechanisms of social support.     

Vulnerability Beliefs, Symptom Experiences, and the Processing of Health Threat Information: A Self-Regulatory Perspective

This study used a self-regulation model of health behavior to explore the impact of risk perceptions and disease-risk symptoms on responses to health messages. Undergraduates with beliefs of high or low vulnerability to heart disease participated in a task that either did or did not induce disease-risk symptoms. Participants were then given a threatening or reassuring message about heart disease prevention, or no message. Participants with high-vulnerability beliefs reported higher exercise intentions only after the reassuring message, and then only in the absence of risk symptoms. However, their exercise rates were increased by both messages and by the symptoms. Participants with preexisting beliefs of low vulnerability reported higher risk perceptions after experiencing the symptoms; only the threat message enhanced their exercise rates.     

How do people evaluate social sexual conduct at work? A psycholegal model

The authors tested a psycholegal model of how people evaluate social sexual conduct at work with videotaped reenactments of interviews with alleged complainants, perpetrators, and other workers. Participants (200 full-time male and female workers) were randomly assigned to evaluate the complaints with either the reasonable person or reasonable woman legal standard. Participants answered questions about sexual harassment law and completed the Ambivalent Sexism Inventory. Participants who took the reasonable woman perspective, as compared with those who took the reasonable person perspective, were more likely to find the conduct harassing; this was especially the case among participants high in hostile sexism. Medium-sized gender effects were found in the severe case but were absent in the weaker, more ambiguous case. The implications of these findings for hostile work environment law are discussed.     

The Use of Environmental Clues During Incubation

ABSTRACT: Three experiments tested the prediction that incubation effects are caused by interactions between activation and environmental clues. Participants worked on 20 experimental problems and then were informed that they would have a second chance to work on the problems. Half were told they might see clues before returning to the problems and were instructed to try to use such clues. Participants then had an incubation period during which they generated words from the letters of test words. The test words were either semantically related to experimental problem answers, the actual answers, or unrelated words. Finally, all participants again tried to solve the experimental problems. Resolution, calculated as the number of items solved during the second trial that were not solved initially, was measured. Participants who saw answers during incubation resolved more items than those who saw related words. In Experiment 3, participants receiving no instructions did not differ across clue conditions, whereas instructed participants who saw answers resolved more problems than those who received related words. Participants in the instructed and unrelated condition performed significantly worse than those in the instructed and answer condition. Incubation effects occurred only when participants who were shown answers were also given instructions. No support was found for the theory that incubation effects are caused solely by environmental clues and activation.     

Group membership influences social control of perpetrators of uncivil behaviors

The present research examined bystanders' reactions to uncivil behaviors. We tested a proposed mediator of the effect by which bystanders are more likely to exert social control over in‐group compared to out‐group members. Participants were asked to report their likely reaction if they were to witness a woman throwing a plastic bottle into a flowerbed. Participants reported that they were more likely to express their disapproval to the woman if she was an in‐group rather than an out‐group member. This effect was mediated by the moral emotions that participants expected the woman to feel if they were to intervene: Participants expected the woman to feel more embarrassment and shame when she was an in‐group member, and this explained why they were more likely to exert social control toward an in‐group member than an out‐group member.

Perceptions of Youth Obesity among Physical Educators

The purposes of this study were to examine (a) antifat attitudes among physical education teachers, (b) performance and ability expectations for normal and overweight youth, and (c) perceptions of the problem of youth obesity and the role of schools and physical education. Participants, 105 physical educators, completed a demographic and background questionnaire, the Antifat Attitudes Scale (AFAS; Morrison & O’Connor), an expectations questionnaire, and Perceptions of Youth Obesity and Physical Education Questionnaire (Price, Desmond, & Ruppert). Participants endorsed moderate antifat attitudes and strong personal weight control beliefs. Participants reported higher expectations for youth they considered normal weight, versus overweight, across a variety of performance and ability areas. Participants overwhelmingly agreed that youth obesity is a concern and that schools are not doing enough to help overweight youth.     

Effects of trainer reputation and trainees' need for cognition on training outcomes

The authors examined the effects of trainer reputation and trainees' need for cognition on training outcomes. Participants (N = 75) read a sheet describing a trainer as either effective or ineffective or they were given no information. Participants then viewed a videotaped lecture, evaluated the lecture, and completed a self-efficacy scale and knowledge test. The authors did not find an interaction of trainer reputation and need for cognition on clarity ratings. Participants with low need for cognition were influenced by the trainer reputation, whereas participants with high need for cognition were not. Self-efficacy mediated the relationship between the interaction of trainer reputation and need for cognition on declarative knowledge.     

Effect of regulating anger and sadness on decision-making

The aim of the current study was to investigate the effects of reappraisal, acceptance, and rumination for regulating anger and sadness on decision-making. Participants (N = 165) were asked to recall two autobiographical events in which they felt intense anger and sadness, respectively. Participants were then instructed to reappraise, accept, ruminate, or not use any strategies to regulate their feelings of anger and sadness. Following this manipulation, risk aversion, and decision-making strategies were measured using a computer-based measure of risk-taking and a simulated real-life decision-making task. Participants who were instructed to reappraise their emotions showed the least anger and sadness, the most adaptive decision-making strategies, but the least risk aversion as compared to the participants in the other conditions. These findings suggest that emotion regulation strategies of negative affective states have an immediate effect on decision-making and risk-taking behaviors.
