All in this together? Group representations and policy support

The present research explored the relationship between how Canadians perceived the quality of intergroup contact with Americans and their support for different antiterrorism policies, considering the potential mediating role of intergroup representations specified in the Common Ingroup Identity Model. Canadian students (n = 360) completed questionnaires that assessed their perceptions of the quality of intergroup contact with Americans, group representations, and reactions to various policies tied to the war against terror. Specifically, we tested a model of how perceptions of the quality of intergroup contact, along the dimensions specified by the Contact Hypothesis, predict different representations of the two groups (Canadians and Americans), and then how these different representations predict reactions to antiterrorist policies. Structural equation modeling analysis supported the predictions, revealing the pivotal role of group representations for policy views.     

The effects of stimulus numerosity,retinal location,and rod contrast on perceived duration of brief visual stimuli

The effects of manipulating three stimulus parameters were determined on a standard perceived duration task using 40- and 70-msec visual stimuli. In Experiment 1, it was found that perceived duration increased with increasing number of target dots but decreased as the area that contained the dots also increased. Experiment 2 examined the effect of varying the retinal location (0, 2, or 4 deg from fovea) of the target dot and found perceived target duration to increase with increasing eccentricity. In Experiment 3, the background luminance for a constant red target was varied so as to alter the scotopic contrast of the target. Perceived duration was minimal for the scotopically matched target and background conditions. The results of all three experiments were discussed in terms of important retinal—and even rod—contributions to tasks of perceived duration.     

Neosexism Among Male Managers: Is It a Matter of Numbers?1

In the last 2 decades, the number of women entering the managerial field has increased. However, this increase has not been equally distributed at all levels. The interest of this study lies in understanding how this sudden surge of women in managerial fields and their unequal distribution across levels are associated with men's reactions toward women. Do men feel threatened by the introduction of women as their coworkers, and if so does this change trigger prejudicial views of women? In all, 123 male managers employed in a Canadian federal agency participated in this study. According to the final path model, as the estimate of the representation of female managers increases, so does male managers' feeling of threat. Feeling threatened along with the estimate of an increase of new female recruits is linked to heightened neosexist views. In turn, neosexism is related to a pro-male bias in the evaluation of women's and men's competence. Additionally, neosexism is negatively associated with men's willingness to support women. Theoretical as well as practical implications of results are discussed.     

Occupational Stressors, Stress Responses, and Alcohol Consumption Among Professional Firefighters: A Prospective, Longitudinal Analysis

This dual-site longitudinal prospective study monitored and measured change in self-reported occupational stressors, emotional trauma, symptoms of stress, and alcohol consumption in urban firefighters. Study participants were 188 firefighters employed by two urban fire departments. The results showed that of 19 occupational stressors examined, only 5 (26%) changed significantly over time, and of those 5, only two—job skill concerns and concerns regarding reduction in force and benefits—decreased, reflecting less bothersome subjective ratings. Of the 12 measures of posttraumatic and other symptoms of stress, 9 (75%) increased significantly over time and none decreased significantly, whereas alcohol consumption was stable over time. Job stressors, trauma caseness, and stress response symptoms at baseline were strongly and significantly associated with the same measures at the two-year follow-up. The implications of the findings for prevention and remediation of stress disorders in fire service personnel are considered. It can be concluded that the stressful nature of urban firefighting is significantly associated with negative health outcomes, including the potential overreliance on alcohol use.     

Duration of the motion aftereffect as a function of retinal locus and visual field.

The duration of the aftereffect induced by viewing a rotating disc was recorded separately for the four hemiretinae of the left and right eyes using a new method of measurement. The results showed duration of aftereffect to differ between nasal and temporal hemiretinae of the right eye and between left and right cerebral hemispheres.     

Personal Relative Deprivation: A Look at the Grievous Consequences of Grievance

Stouffer et al. (1949) have first coined the term ‘relative deprivation’ to account for unexpected grievance expressed by members of a fortunate group. Many researchers have built on this work and have concluded that a person's feeling of deprivation is relative rather than absolute. In other words, deprivation stems from a social comparison with better‐off persons. In this chapter, a brief summary of the ground‐breaking research on relative deprivation is presented followed by an overview of research on overt and covert responses to personal relative deprivation. In accounting for the silent reactions of the underprivileged, we mainly focus on recent research linking personal relative deprivation to psychological disengagement. Turning to the responses of members of privileged groups, we take into account personal relative deprivation and gratification. Our concluding remarks suggest that responses of both the underprivileged and the privileged concur to the maintenance of the status quo.     

First record: a methodological approach to counter sampling bias

One goal of survey research is to optimize sampling procedures so that the collected data will produce accurate population estimates. In this context, sampling bias is a primary threat to a study's validity. If individuals who do not respond are a random sample of the population, then the estimates obtained from such a subsample are unbiased. However, as the percentage of nonrespondents increases, the assumption of unbiased estimation becomes increasingly tenuous. At this point an investigator has two choices: delete all subjects who have not provided data as part of the first data collection, or allow a respondent's point of entry to define his baseline measures for the study. No previous discussion of the latter option has been noted in the methods literature. Therefore the authors have termed this approach to baseline the "first record". Conditions under which the "first record" technique would be appropriate or inappropriate are discussed.     

Sampling Bias and Other Methodological Threats to the Validity of Health Survey Research

Data from a longitudinal occupational health survey of professional fire fighters were used to explore the potential impact of two types of methodological bias: sample selection and reactivity. No significant differences on demographic variables were observed between the group who first responded after a within-study change in survey administration format (Delayed) and respondents who had completed surveys since the study's inception (Initial). However, statistically significant differences in the study's 26 outcome measures provided some evidence that between-group differences did exist and that an administration format type of response bias was also potentially present. The effect sizes associated with the 37 observed significant differences ranged from small to medium. These results provide a context for a reexamination of standard techniques for the identification and interpretation of survey research biases. Methods are suggested to strengthen tests for selection bias and to minimize the impact of response biases.
