Put your money where your mouth is! Explaining collective action tendencies through group-based anger and group efficacy 总被引:1,自引:0,他引:1

Insights from appraisal theories of emotion are used to integrate elements of theories on collective action. Three experiments with disadvantaged groups systematically manipulated procedural fairness (Study 1), emotional social support (Study 2), and instrumental social support (Study 3) to examine their effects on collective action tendencies through group-based anger and group efficacy. Results of structural equation modeling showed that procedural fairness and emotional social support affected the group-based anger pathway (reflecting emotion-focused coping), whereas instrumental social support affected the group efficacy pathway (reflecting problem-focused coping), constituting 2 distinct pathways to collective action tendencies. Analyses of the means suggest that collective action tendencies become stronger the more fellow group members "put their money where their mouth is." The authors discuss how their dual pathway model integrates and extends elements of current approaches to collective action. 相似文献

The authors investigated the impact of different motor demands on space- and object-based attention allocation. Responses to targets were either lifting a finger, or pointing to the target, or grasping a clay object placed on the target location. Reaction times and movement times were recorded to assess covert and overt attention, respectively. Both reaction times and movement times showed more space-based attention for pointing than for finger lifting and more object-based attention for grasping than for pointing. That result supports the view that visual selectivity is tuned to specific motor intentions (H. Bekkering & F. W. Neggers, 2002) and illustrates the tight coupling of perception and action. 相似文献

Some well-known geometrical illusions disappear when the eyes are fixating and saccades are suppressed for a period of time. This disappearance is not accompanied by fading due to stabilisation of the retinal image. Any saccade made on purpose restores the illusion immediately. The fixation time after which some illusions disappeared was measured for four illusions and four subjects each. Effects of practice have been observed after measurements were repeated on successive days. Present theories of vision cannot readily explain the effect. 相似文献

Two studies on political hindsight bias were conducted on the occasions of the German parliament election in 1998 and the Nordrhein-Westfalen state parliament election in 2000. In both studies, participants predicted the percentage of votes for several political parties and recalled these predictions after the election. The observed hindsight effects were stronger than those found in any prior study on political elections (using percentage of votes as the dependent variable). We argue that the length of the retention interval between original judgement and recollection is mainly responsible for this difference. In our second study, we investigated possible artifacts in political hindsight biases using a control-group design where half of the participants recalled their predictions shortly before or after the election. Hindsight bias was preserved, reinforcing the results of earlier studies with non-control-group designs. Finally, we discuss the possibility that the hindsight experience (in political judgement and in general) actually consists of three different, partly independent components. 相似文献

For graduate students to succeed as professionals, they must develop a set of general "survival skills". These include writing research articles, making oral presentations, obtaining employment and funding, supervising, and teaching. Traditionally, graduate programs have offered little training in many of these skills. Our educational model provides individuals with formal instruction in each area, including their ethical dimensions. Infusion of research ethics throughout a professional skills curriculum helps to emphasize that responsible conduct is integral to succeeding as a researcher. It also leads to the consideration of ethical dimensions of professional life not covered in traditional ethics courses. 相似文献

The Corsi Blocks task (CBT) measures spatial memory span, but methodological differences across previous studies prevent a clear appreciation of perceptual, memory, and motor contributions to spatial span. CBT performance in a standard condition was compared to performance with longer encoding intervals (3 vs 1 s), longer memory intervals (9 vs 1 s), or fewer response alternatives (all nine vs only the relevant positions). All experiments also contrasted ascending vs descending order of item difficulty and recorded response-initiation times. Performance improved with longer encoding and maintenance intervals and with fewer response alternatives. Item order had no reliable effects. Response-initiation times were a useful additional measure of spatial span. Implications of these findings for research using the CBT are discussed. 相似文献

This study investigated familial and behavioral differences between Hispanic and Anglo-American first-year college students. Analyses of variance and chi-square analyses were used to test for ethnic differences in (a) risk factors associated with family dysfunction, family addictions, personality factors, and social experiences, (b) student problem behaviors, namely alcohol use, drug use, and eating disorders, (c) a one-year follow-up of student retention, and (d) specific factors related to retention at the one-year follow-up. The Hispanic freshmen appeared to demonstrate resilience despite a lack of mentoring and greater paternal addiction. However, the one-year follow-up suggested that Hispanic females were at particular risk for leaving school. To improve college retention rates, social policy should focus on Hispanic students' vulnerabilities and strengths in making important developmental transitions. 相似文献

Sentences were presented in various spatial formats, and readers localised one word of each sentence using a mouse cursor directly after reading. There was a localisation advantage for cumulative over single-word displays, for left-to-right presentation over presentation in a 3 x 3 grid, and for complete over incomplete sentences. Comparing performance for predictable and unpredictable word locations suggests that word location memory in reading decays within three seconds to a span of only 2-3 entries, and that readers can then reconstruct word locations from item memory. Implications for the role of spatial cognition in reading are discussed. 相似文献

An important current debate concerns the originof gender differences in partner preferences. Thesedifferences have been explained both in terms ofevolutionary theory and in terms of social role theory. The present study determines the relativestrengths of both perspectives by investigating, apartfrom gender, the influence of three other importantfactors on partner preferences and for which the two approaches offer divergent hypotheses: age,political orientation and level of education of therespondent. About 95% of the participants were WhiteDutch citizens, the rest were Dutch with one or twoparents from a different ethnic background.Participants were requested to write down the mostimportant characteristics of a potential partner(open-ended format), followed by an instruction toindicate the importance of 39 pre-selected characteristics. Resultsshow that men and women have highly similar preferencesfor characteristics in a potential partner. In addition,it is demonstrated that on crucial characteristics from an evolutionary perspective (i.e.,physical attractiveness and status) significantinteractions between age, political orientation, levelof education and/or gender of the respondents emerge.Most results offer support for a social role theoryof human mate selection. It is concluded that becausegender on its own merely explains a small proportion ofthe total variance in human mate selection, it is important to include other factors, not onlyin order to facilitate our understanding of the fullcomplexity of partner preferences, but also in order tomake theoretical progress in this area. 相似文献
