RESUMEN

Facial cues of threat such as anger and other race membership are detected preferentially in visual search tasks. However, it remains unclear whether these facial cues interact in visual search. If both cues equally facilitate search, a symmetrical interaction would be predicted; anger cues should facilitate detection of other race faces and cues of other race membership should facilitate detection of anger. Past research investigating this race by emotional expression interaction in categorisation tasks revealed an asymmetrical interaction. This suggests that cues of other race membership may facilitate the detection of angry faces but not vice versa. Utilising the same stimuli and procedures across two search tasks, participants were asked to search for targets defined by either race or emotional expression. Contrary to the results revealed in the categorisation paradigm, cues of anger facilitated detection of other race faces whereas differences in race did not differentially influence detection of emotion targets.

RESUMEN

Using the belief basis of the theory of planned behavior (TPB), the current study explored the rate of mild reactions reported by donors in relation to their first donation and the intention and beliefs of those donors with regard to returning to donate again. A high proportion of first-time donors indicated that they had experienced a reaction to blood donation. Further, donors who reacted were less likely to intend to return to donate. Regression analyses suggested that targeting different beliefs for those donors who had and had not reacted would yield most benefit in bolstering donors' intentions to remain donating. The findings provide insight into those messages that could be communicated via the mass media or in targeted communications to retain first-time donors who have experienced a mild vasovagal reaction.

RESUMEN

A randomized controlled trial evaluated the effectiveness of a 4-wk extended theory of planned behavior (TPB) intervention to promote regular physical activity and healthy eating among older adults diagnosed with Type 2 diabetes or cardiovascular disease (N = 183). Participants completed TPB measures of attitude, subjective norm, perceived behavioral control, and intention, as well as planning and behavior, at preintervention and 1 wk and 6 wk postintervention for each behavior. No significant time-by-condition effects emerged for healthy eating. For physical activity, significant time-by-condition effects were found for behavior, intention, planning, perceived behavioral control, and subjective norm. In particular, compared with control participants, the intervention group showed short-term improvements in physical activity and planning, with further analyses indicating that the effect of the intervention on behavior was mediated by planning. The results indicate that TPB-based interventions including planning strategies may encourage physical activity among older people with diabetes and cardiovascular disease.

RESUMEN

Earlier research found evidence for electro-cortical race bias towards black target faces in white American participants irrespective of the task relevance of race. The present study investigated whether an implicit race bias generalizes across cultural contexts and racial in- and out-groups. An Australian sample of 56 Chinese and Caucasian males and females completed four oddball tasks that required sex judgements for pictures of male and female Chinese and Caucasian posers. The nature of the background (across task) and of the deviant stimuli (within task) was fully counterbalanced. Event-related potentials (ERPs) to deviant stimuli recorded from three midline sites were quantified in terms of mean amplitude for four components: N1, P2, N2 and a late positive complex (LPC; 350-700 ms). Deviants that differed from the backgrounds in sex or race elicited enhanced LPC activity. These differences were not modulated by participant race or sex. The current results replicate earlier reports of effects of poser race relative to background race on the LPC component of the ERP waveform. In addition, they indicate that an implicit race bias occurs regardless of participant's or poser's race and is not confined to a particular cultural context.

RESUMEN

The present study tested the utility of an extended version of the theory of planned behaviour that included a measure of planning, in the prediction of eating foods low in saturated fats among adults diagnosed with Type 2 diabetes and/or cardiovascular disease. Participants (N=184) completed questionnaires assessing standard theory of planned behaviour measures (attitude, subjective norm, and perceived behavioural control) and the additional volitional variable of planning in relation to eating foods low in saturated fats. Self-report consumption of foods low insaturated fats was assessed 1 month later. In partial support of the theory of planned behaviour, results indicated that attitude and subjective norm predicted intentions to eat foods low in saturated fats and intentions and perceived behavioural control predicted the consumption of foods low in saturated fats. As an additional variable, planning predicted the consumption of foods low in saturated fats directly and also mediated the intention-behaviour and perceived behavioural control-behaviour relationships, suggesting an important role for planning as a post-intentional construct determining healthy eating choices. Suggestions are offered for interventions designed to improve adherence to healthy eating recommendations for people diagnosed with these chronic conditions with a specific emphasis on the steps and activities that are required to promote a healthier lifestyle.

RESUMEN

The present studies investigated the processes by which group members integrate a new social identity. Based on a newly developed theoretical model, we anticipated that social factors (social support and need satisfaction) would be facilitators of this change process and should have an impact on the coping and adaptation strategies group members use to deal with the membership in a new group. These strategies, in turn, should predict intra-individual changes in level of identification with the new group, which should then predict enhanced psychological adjustment over time. The proposed associations were tested among university students over the course of their first academic year (Study 1) and among on-line gamers joining a newly established on-line community (Study 2). Path analyses provided support for the hypothesized associations. The results are discussed in light of recent theoretical developments pertaining to intra-individual changes in social identities.

RESUMEN

Previous research has suggested that like animal and social fear-relevant stimuli, other-race faces (African American) are detected preferentially in visual search. Three experiments using Chinese or Indonesian faces as other-race faces yielded the opposite pattern of results: faster detection of same-race faces among other-race faces. This apparently inconsistent pattern of results was resolved by showing that Asian and African American faces are detected preferentially in tasks that have small stimulus sets and employ fixed target searches. Asian and African American other-race faces are found slower among Caucasian face backgrounds if larger stimulus sets are used in tasks with a variable mapping of stimulus to background or target. Thus, preferential detection of other-race faces was not found under task conditions in which preferential detection of animal and social fear-relevant stimuli is evident. Although consistent with the view that same-race faces are processed in more detail than other-race faces, the current findings suggest that other-race faces do not draw attention preferentially.

RESUMEN

The present research investigated three approaches to the role of norms in the theory of planned behaviour (TPB). Two studies examined the proposed predictors of intentions to engage in household recycling (Studies 1 and 2) and reported recycling behaviour (Study 1). Study 1 tested the impact of descriptive and injunctive norms (personal and social) and the moderating role of self-monitoring on norm-intention relations. Study 2 examined the role of group norms and group identification and the moderating role of collective self on norm-intention relations. Both studies demonstrated support for the TPB and the inclusion of additional normative variables: attitudes; perceived behavioural control; descriptive; and personal injunctive norms (but not social injunctive norm) emerged as significant independent predictors of intentions. There was no evidence that the impact of norms on intentions varied as a function of the dispositional variables of self-monitoring (Study 1) or the collective self (Study 2). There was support, however, for the social identity approach to attitude-behaviour relations in that group norms predicted recycling intentions, particularly for individuals who identified strongly with the group. The results of these two studies highlight the critical role of social influence processes within the TPB and the attitude-behaviour context.

RESUMEN

BACKGROUND: Donor retention poses a significant problem to blood collection agencies around the world. Previous research using an augmented theory of planned behavior (TPB) approach has demonstrated that attitude, subjective norm, self-efficacy, moral norm, anticipated regret, donation anxiety from prior blood donations, and self-identity as a blood donor predicts experienced donors' intentions and that intentions, self efficacy, moral norm, and anticipated regret may impact upon people's actual blood donation behavior. STUDY DESIGN AND METHODS: Established blood donors (n = 263) completed questionnaires assessing standard TPB constructs, anticipated regret, moral norm, donation anxiety, and self-identity as a blood donor. Three months later, a second questionnaire assessing blood donation behavior in the intervening 3 months was mailed and returned by 182 donors. RESULTS: With structural equation modeling, the final augmented TPB model provided an excellent fit to the data and included a direct path from intention to behavior and indirect paths to behavior through intention for attitude, self-efficacy, and anticipated regret. Moral norm, donation anxiety, and donor identity indirectly predicted intention through attitude. In total, 51 percent of the variance in donors' attitudes, 86 percent of variance in donors' intentions, and 70 percent of the variance in donors' behavior were accounted for in the final model. CONCLUSION: An augmented TPB framework proved efficacious in determining the predictors of the intentions and behavior of established blood donors. Further, this framework highlighted the importance of considering in the future how donors' motivations for donating blood may evolve as a function of the number of prior donations.

RESUMEN

BACKGROUND: With an increasing demand for blood and blood products in Australia, there is a continual need to recruit blood donors. As such, it is important to investigate the factors that impact on nondonors' decision-making processes with regard to donating blood for the first time. Previous research has established the efficacy of the theory of planned behavior (TPB) in predicting blood donor intentions. The current research aimed to test a TPB model augmented with constructs implicated in previous blood donor research; specifically descriptive norm, moral norm, anticipated regret, and donation anxiety. STUDY DESIGN AND METHODS: Participants completed measures assessing the standard TPB variables of attitude, subjective norm, and perceived behavioral control (PBC) as well as descriptive norm, moral norm, donation anxiety, and anticipated regret. Path analysis examined the utility of the augmented TPB model to predict 195 non-blood donors' intentions to donate blood. RESULTS: A final revised model provided a very good fit to the data and included attitude, PBC, moral norm, descriptive norm, anticipated regret, and donation anxiety as direct predictors of intention, with these factors accounting for 70 percent of the variance in intentions to donate blood. CONCLUSION: A revised TPB model provided a more efficacious predictor of nondonors' intentions to donate than the standard TPB model and highlights the role that norm-based factors and affective-laden constructs play in predicting non-blood donors' intentions to donate.

RESUMEN

The authors used a revised planned behavior model in the consumer domain. The revised model incorporated separate measures of descriptive and injunctive/ prescriptive norms, self-identity, and past behavior in an effort to improve the predictive power of the theory of planned behavior (TPB; I. Ajzen, 1985) in relation to a self-reported consumer behavior: purchasing one's preferred soft drink. At Time 1, respondents (N = 112) completed self-report measures of (a) attitudes, (b) perceived behavioral control, (c) descriptive and injunctive/prescriptive norms, (d) self-identity, (e) past behavior, and (f) intentions. The authors assessed self-reported behavior 1 week later (Time 2). Attitudes, injunctive/prescriptive norms, descriptive norms, past behavior, and self-identity were all positively related to purchase intentions, and intentions were predictive of self-reported behavior at Time 2. These findings highlight the utility of the TPB in the consumer domain.

RESUMEN

Coping efforts have been recognised as an important aspect of resilience following traumatic brain injury, but little is known about what constitutes effective coping in this population. This longitudinal research examined the usefulness of the Goodness-of-Fit hypothesis, drawn from the Lazarus and Folkman [(1984). Stress, appraisal and coping. NY: Springer.] theory of stress and coping, as a way of understanding coping effectiveness. The hypothesis suggests that the nature and success of specific coping strategies will be associated with the controllability of the event. If an event is relatively uncontrollable, then emotion-focused or perception-focused coping may be more effective than problem-focused coping. In contrast, a controllable event may be best managed through problem-focused coping. Ninety people with traumatic brain injury, drawn from the inpatient rehabilitation unit of a major metropolitan hospital in Australia, and their relatives participated in this longitudinal study. No support was found for the Goodness-of-Fit model, either in the short term or the long term. Although the use of problem-focused coping strategies was positively associated with short-term and long-term role functioning, it was not associated with long-term emotional well-being if the situation was perceived to be controllable. The findings suggest that the persistent use of problem-focused coping in response to the difficulties created by traumatic brain injury can be associated with emotional distress in the long term. Reasons for this finding are explored and its implications are discussed.

RESUMEN

With an ever-increasing demand on blood supplies worldwide, there is an immense need to ensure a safe and sufficient supply of blood products. However, recruiting and retaining blood donors remain key challenges for blood agencies. In an attempt to address these problems, researchers have identified a range of sociodemographic, organizational, physiological, and psychological factors that influence people's willingness to donate blood. Although past research has largely focused on donor recruitment, in particular, demographic variables associated with blood donation behavior, the issue of donor retention has become increasingly important. A growing number of studies have also highlighted the role of psychological factors in explaining, predicting, and promoting blood donation behavior. In line with recent trends in blood donation research, the present article reviews the contributions of, and current directions in, psychological research on blood donation attitudes and behavior, with special emphasis on donor return and repeat blood donation behavior. Although there is overlap between factors that predict the initiation and the maintenance of blood donation behavior, it is suggested that changes in motivation and the development of self-identity as a blood donor are crucial for understanding the processes whereby first-time donors become repeat donors.

RESUMEN

The present research integrates core aspects of social identity theory with the theory of planned behaviour to investigate factors influencing engagement in sustainable agricultural practices. Using a two-wave prospective design, two studies were conducted with samples of farmers (N = 609 and N = 259, respectively). At Time 1, a questionnaire survey assessed theory of planned behaviour variables in relation to engaging in riparian zone management (a sustainable agricultural practice). In addition, intergroup perceptions (i.e. relations between rural and urban groups), group norms and group identification were assessed. At Time 2, self-reported behaviour was measured. There was support for the integrated model across both studies. As predicted, past behaviour, attitudes and perceived behavioural control were significant predictors of intentions, and intentions significantly predicted self-reported behaviour. Group norms and intergroup perceptions were also significant predictors of intentions providing support for the inclusion of social identity concepts in the theory of planned behaviour. More supportive group norms were associated with higher intentions, especially for high-group identifiers. In contrast, more negative intergroup perceptions were associated with lower intentions and, unexpectedly, this effect only emerged for low-group identifiers. This suggests that in the context of decisions to engage in riparian zone management, an important sustainable agricultural practice, high identifiers are influenced predominantly by in-group rather than out-group considerations, whereas low identifiers may attend to cues from both the in-group and the out-group when making their decisions.

RESUMEN

An experiment tested the hypothesis that individuals high in negative affectivity (NA) show increased stress reactivity to stressors. There were three predictor variables: NA (measured 1 week prior to experimental participation), and two manipulated variables--demand (high/low) and behavioral control (high/low). First-year psychology students (n = 256) were randomly allocated to one of the four experimental conditions. Measures obtained were initial and post-task negative mood, coping strategies, task satisfaction, and performance (subjective and objective). Participants with high levels of NA reported more post-task negative mood in response to high demand conditions, compared to participants with low NA. A similar pattern of results emerged for task satisfaction, particularly in response to high demand-low behavioral control situations. Mediation analyses suggested this was because participants with high NA used more emotion-focused coping strategies. The study provides support for the stress reactivity role of NA in the stressor-strain process.

RESUMEN

Two studies were conducted to examine the impact of subjective uncertainty on conformity to group norms in the attitude-behaviour context. In both studies, subjective uncertainty was manipulated using a deliberative mindset manipulation (McGregor, Zanna, Holmes, & Spencer, 2001). In Study 1 (N=106), participants were exposed to either an attitude-congruent or an attitude-incongruent in-group norm. In Study 2 (N=83), participants were exposed to either a congruent, incongruent, or an ambiguous in-group norm. Ranges of attitude-behaviour outcomes, including attitude-intention consistency and change in attitude-certainty, were assessed. In both studies, levels of group-normative behaviour varied as a function of uncertainty condition. In Study 1, conformity to group norms, as evidenced by variations in the level of attitude-intention consistency, was observed only in the high uncertainty condition. In Study 2, exposure to an ambiguous norm had different effects for those in the low and the high uncertainty conditions. In the low uncertainty condition, greatest conformity was observed in the attitude-congruent norm condition compared with an attitude-congruent or ambiguous norm. In contrast, individuals in the high uncertainty condition displayed greatest conformity when exposed to either an attitude-congruent or an ambiguous in-group norm. The implications of these results for the role of subjective uncertainty in social influence processes are discussed.

RESUMEN

Using an intergroup perspective, this longitudinal study (N=215) examined the adjustment patterns of employees from low vs. high status pre-merger organizations. The first questionnaire was distributed 3 months after the implementation of the merger, whereas the second was completed 2 years later. As predicted, members of the low status group perceived the merger to be implemented in a less fair manner at the start of the merger and reported a decreased adjustment to the merger over time. Members of the high status group showed an increase in adjustment over time, lower in-group bias and a stronger identification with the new merged organization. Path analyses further confirmed that identification with the new merged organization mediated the associations between perceptions of fairness and in-group bias as well as changes in adjustment over time. With its longitudinal design, this study replicates and extends past results by revealing the predictors of adjustment for members of low vs. high status groups involved in an intergroup merger.

RESUMEN

Promoting healthy lifestyle behaviors is an important aspect of interventions designed to improve the management of chronic diseases such as Type 2 diabetes and cardiovascular disease. The present study used Ajzen's (1991) theory of planned behavior as a framework to examine beliefs amongst adults diagnosed with these conditions who do and do not engage in low-fat dietary and regular physical activity behaviors. Participants (N = 192) completed a questionnaire assessing their behavioral, normative and control beliefs in relation to regular, moderate physical activity and eating foods low in saturated fats. Measures of self-reported behavior were also examined. The findings revealed that, in general, it is the underlying behavioral beliefs that are important determinants for both physical activity and low-fat food consumption with some evidence to suggest that pressure from significant others is an important consideration for low-fat food consumption. Laziness, as a barrier to engaging in physical activity, also emerged as an important factor. To encourage a healthy lifestyle amongst this population, interventions should address the perceived costs associated with behavioral performance and encourage people to maintain healthy behaviors in light of these costs.

RESUMEN

This article presents a model of social identity development and integration in the self. Classic intergroup theories (e.g., social identity theory, self-categorization theory) address the situational, short-term changes in social identities. Although these theories identify the contextual and environmental factors that explain situational changes in social identification, the intraindividual processes underlying developmental changes in social identities and their integration within the self remain to be identified. Relying on recent intergroup models as well as on developmental (i.e., neo-Piagetian) and social cognitive frameworks, this article proposes a four-stage model that explains the specific processes by which multiple social identities develop intraindividually and become integrated within the self over time. The factors that facilitate versus impede these identity change processes and the consequences associated with social identity integration are also presented.

RESUMEN

Employees of merging organizations often show resistance to the merger. The employees' support depends on the companies' premerger status and on the merger pattern. Based on an intergroup perspective, three studies were conducted to investigate the influence of premerger status (high, low) and merger pattern (assimilation, integration-equality, integration-proportionality, transformation) on participants' support for a pending organizational merger. Students (Study 1) and employees (Study 2) had to take the perspective of employees of a fictitious merging organization. Study 3 investigated students' perceptions of a potentially pending university merger using a 2 (status) x 3 (merger pattern: assimilation, integration-equality, integration-proportionality) design. Across all studies, the low-status group favored integration-equality and transformation whereas the high-status group preferred integration-proportionality and assimilation. Perceived threat mediated the effects. Legitimacy was a stronger mediator for effects of the low-status group.
