Thought suppression,intelligence, and working memory capacity

The importance of individual differences in intelligence and working memory capacity in predicting the ability to intentionally suppress thoughts was investigated. Sixty participants completed a thought suppression task, and measures of working memory capacity (OSPAN), fluid intelligence (Raven's Matrices), and crystallised intelligence (the National Adult Reading Test). As predicted, the results indicated that more effective thought suppression was independently related to higher working memory capacity and greater fluid intelligence, but was unrelated to crystallised intelligence. The findings have theoretical implications for understanding the mechanisms underlying a failure to inhibit unwanted intrusions and clinical implications for disorders involving high levels of intrusive thoughts and memories.     

Love It or Leave It: A Look at Women in Clerical Occupations1

This study was conducted among female clerical workers to examine factors associated with attitudes toward bridging programs. These programs facilitate women's transition from traditional to nontraditional careers. In a proposed model, 2 paths linking masculine and feminine traits of the self‐concept to personal relative deprivation were tested. Whereas feminine traits were expected to correlate with masculine traits, the former was predicted to yield feelings of relative satisfaction and the latter to evoke relative deprivation. Relative deprivation was predicted to increase intention to endorse bridging program activities. Results support the model, albeit analyses suggested an additional path from masculine traits to bridging program activities. Implications of this reality test of the relations between self‐concept, relative deprivation, and career mobility are discussed.     

Coping in Caregivers of Youth with Spinal Cord Injury

This study examined coping among caregivers of youth with spinal cord injuries (SCI). Using a cross-sectional survey study design, 164 caregivers completed a demographics questionnaire and the Brief COPE. Their children, youth with SCI ages 7–18, completed the Kidcope. T-tests were conducted to examine differences in caregiver coping by demographic and injury-related factors. Further, logistic regression models were evaluated to examine predictive relationships between caregiver coping and youth coping. Several demographic and injury-related factors were related to caregiver coping, including caregiver gender, race, and education, as well as youth gender, age at injury, and time since injury. In the logistic regressions, two caregiver coping strategies were related to youth coping: caregiver self-blame coping was related to youth self-criticism, and caregiver behavioral disengagement coping (giving up attempts to cope) was related to youth blaming others coping. The findings suggest that caregiver coping may play a role in the coping of their children, and should be considered when addressing coping among youth with SCI.     

A functional analysis and treatment of the irrational and rational statements of an elderly woman with Alzheimer's disease

Speech problems are a hallmark of Alzheimer's disease. Although often attributed to neurological damage common to the disease speech problems have been successfully treated through the use of behavior analytic techniques. This study was a replication and extension of that line of research. The participant in this study was an elderly woman diagnosed with Alzheimer's who was referred for services due to frequent irrational statements and infrequent rational statements. Both standard functional analysis and modified functional analysis conditions were conducted. It appeared the irrational statements were controlled by social reinforcement. Several treatment packages consisting of differential reinforcement of incompatible behaviors and extinction components were implemented in an ABCDEAE treatment design. Results of the study suggest the intervention successfully increased rational statements but had no effect on irrational statements. These results indicate the need for further research on the conditions under which behavior analysis techniques will be most effective. Copyright © 2006 John Wiley & Sons, Ltd.     

Helping the Less Fortunate: A Predictive Model of Collective Action

A model of factors that lead members of an advantaged group to perform collective action intended to help a disadvantaged out-group is tested. A distinction is made between easy and demanding collective activities. Two different routes are expected to lead to collective action. First, an indirect link is proposed between a common in-group identity and collective action. This link is believed to be mediated by perceived mobilization resources. Second, the link between relative deprivation on behalf of others (RDBO) and collective action will vary according to the type of behavior considered. While, RDBO is expected to be directly associated with easy collective behavior, the link between RDBO and demanding collective activities is mediated through perceived mobilization resources. In turn, perceived resources are linked to both forms of collective behaviors. The predicted model is tested among 273 undergraduate respondents. Findings point to the relevance of all factors considered and the pivotal role of perceived mobilization resources on collective action.     

Effects of interval duration on temporal processing in schizophrenia

INTRODUCTION: Temporal processing has received scant attention in the literature pertaining to cognitive deficits in patients with schizophrenia. Previous research suggests that patients with schizophrenia exhibit temporal perception deficits on both auditory and visual stimuli. The current study investigated the effects of interval manipulation to (1) replicate the original findings with a larger sample and an increased number of trials (2) assess the degree to which both patients and controls can differentiate temporal changes in a range of experimental interstimulus intervals, and (3) explore whether different interstimulus interval durations pose different levels of difficulty for the patients with schizophrenia. METHODS: Participants were asked to decide whether temporal intervals were shorter or longer than standard intervals on a computer-based auditory temporal perception task. The standard interval remained the same duration throughout the various tasks. The interstimulus interval separating the standard and experimental intervals varied in the range of 500, 1000, or 3000 ms. Data are presented for a sample of 16 patients with schizophrenia and 15 controls. RESULTS: Data suggest that patients with schizophrenia exhibit deficits in differentiating interval durations across all paradigms compared to their control-group peers on a range of auditory tasks (p<.001). CONCLUSIONS: These results are consistent with a general temporal deficit in schizophrenia. However, the roles of medication and localization are also addressed.     

Work and nonwork stressors,negative affective states,and pain complaints among firefighters and paramedics

Prior research has suggested that occupational stressors may contribute to the etiology, progression, and chronicity of pain problems in workers. This study used anonymous survey methods to assess the prevalence and frequency of self-reported pain symptoms and their relationships to demographic variables, sources of occupational stressors, nonwork stressors and affective distress in a large sample (N2000) of employed career public sector firefighters and paramedics. The findings were consistent with those of previous studies of high strain workers. More than 95% of the firefighter/paramedic sample reported at least one pain complaint (using a 1 week assessment time frame). A hierarchical multiple regression analysis entering demographic, occupational, and nonwork stressors, as well as measures of negative affective states targeting total pain scores, yielded significant relationships. Five occupational stressors were associated with respondent pain complaints. The results also suggest that negative affective states mediated the relationships between work and nonwork variables, and pain complaint outcomes. The implications of these findings for the development of preventive interventions for firefighters and paramedics as well as other emergency service workers are considered.     

Why Women Approve of Affirmative Action: The Study of a Predictive Model

The self-interest model has often been used to predict the reactions of advantaged groups to affirmative action. It is argued that self-interest also plays a role in the genesis of attitudes of disadvantaged groups, such as women. More precisely, it is hypothesised that considerations of personal interest have an impact on considerations of collective interest which in turn have an impact on the sense of collective relative deprivation (CRD). In the past, it was shown that women who felt collectively deprived approved of strategies designed to eliminate systemic barriers. No link was found, however, between CRD and preferential treatment. Women, in majority, were opposed to this strategy. On the basis of a model introduced by Taylor and McKirnan (1984), it is argued that women who have experienced discrimination on the basis of sex in spite of the introduction of affirmative action strategies may support preferential treatment. The hypotheses were integrated in a model and tested using LISREL causal modelling. In total, 197 female francophone workers participated in the study. They were all employed in a large firm where in the last five years attempts were made to reduce sex asymmetries. These efforts however were not successful; the percentage of women in non-traditional jobs increased by only 2%. The proposed model was tested successfully. The results are discussed in light of previous paradigms and practical implications.     

Hemispheric emotional asymmetry in a dichotic listening task.

In a dichotic listening experiment white noise was played to one ear and either music or poetry to the other ear. Subjects rated the stimuli on each of three dimensions. The results showed that both music poetry were judged as more pleasant when heard at the left than the right ear. In addition the music, but not the poetry, was perceived as more soothing at the left ear. The findings are discussed in relation to other indications in the literature that left and right cerebral hemispheres differ in their emotional make-up.     

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.
