According to the behavior from intergroup affect and stereotypes (BIAS) map, groups stereotyped as cold and competent receive active harm and passive facilitation, whereas groups stereotyped as warm and incompetent receive active facilitation and passive harm. Extending previous research, we conducted four studies to examine what determines helping and what determines harming behaviors toward ambivalent groups. In Study 1 (N = 58) we demonstrated that groups stereotyped as cold and competent evoke intentions of active harm due to a relative salience of their lack of warmth, whereas they elicit intentions of passive facilitation due to a relative salience of their competence. In Study 2 (N = 88) we demonstrated that groups stereotyped as warm and incompetent elicit intentions of active facilitation due to a relative salience of their warmth, whereas they elicit intentions of passive harm due to a relative salience of their lack of competence. Studies 3 (N = 54) and 4 (N = 67) replicated these findings and further demonstrated that the effects on active, but not passive, behaviors were mediated by distinct emotions. Implications for ambivalent groups are discussed.  相似文献

Previous research on video gaming mainly focused on negative impact on users. In this study, the positive impact of action video gaming among congenitally deaf subjects is investigated. Subjects possessed high level of visual information processing capacity. A 96 h of action video game play resulted in the improvement of mean reaction time (mRT) (post = 413.21 ms, pre = 453.39 ms) and certain cognitive functions. Higher heart rate variability (HRV) subjects demonstrated faster and significant improvement in mRT (p < 0.0045) after intervention. The α and β EEG band powers were found increased in parietal (6.33%, 4.28%) and occipital (8.38%, 38%) lobes respectively. The θ band power increased in frontal (32%) and parietal (13%) lobes. These results can reflect enhancement in certain cognitive performances such as visual perception, attention, memory, and motor skills. The ratio index β/(α + θ) increased in frontal and occipital lobes while β/θ increased in frontal and temporal lobes. These results may also suggest improvements in attention processing capacity and neural activity. These results implies improvements in certain aspects of cognition among deaf subjects. However, to validate these results a further study on larger number of samples with advanced computerized cognitive battery testing can be employed.  相似文献

The theory of planned behavior (TPB, Ajzen, 1985) has proved its efficiency in predicting different behaviors among road users (Sheeran & Orbell, 2000). The present study examined the TPB factors explaining risk taking among vulnerable road users (e.g., cyclists). We presumed that attitude, social norms, and perceived behavioral control (PBC) would predict cyclists’ intention to adopt a risky behavior in two traffic contexts considered as risk-conducive (i.e., run the red-light, turn left).Participants (N = 224, Mage = 23.34) filled in an online scenario-based questionnaire describing two traffic situations conducive to risk taking and including measures for cyclists’ intentions to adopt risky behaviors in these specific contexts, TPB factors, and self-perceived efficacy.TPB factors explained 49% and 65% of the variance in the intention to cross the red light, respectively the intention to turn left, with positive attitude and high PBC as the best predictors. Implications of the results were discussed.  相似文献

ObjectivesThis study investigated implicit and explicit components of exerciser self-schema and their role in the prediction of exercise behaviour. In addition, the effect of implicit and explicit exerciser self-schema on intention to exercise was examined. Moderation and mediation effects involving exerciser self-schema, in both its implicit and explicit forms, were investigated.MethodMembers of fitness centres and other regular exercisers (N = 98, nmales = 37, nfemales = 65) completed a written questionnaire to measure explicit exerciser self-schema and exercise intentions. An exercise Implicit Association Test (IAT) was also administered to measure implicit exerciser self-schema. Actual exercise occurrence was measured one week and two weeks following the initial testing phase.ResultsCorrelations indicated that implicit and explicit components of exerciser self-schema were related but distinct constructs. Hierarchical regression analysis revealed that high levels of both implicit and explicit exerciser self-schema improved absolute levels of exercise behaviour. Regression analyses examining the possibility that self-schema moderated the intention–behaviour relationship were not significant for implicit or explicit forms of self-schema. Forced entry regression analyses provided evidence for explicit exerciser self-schema being mediated by intention in its relationship with behaviour.ConclusionsIt is beneficial to consider both implicit and explicit exerciser self-schema when attempting to understand and predict exercise behaviour. Both implicit and explicit exercise self-schema have a direct effect on behaviour, although explicit self-schema also indirectly influences behaviour via intention to exercise.  相似文献

Behavioral treatments for diabetes have often been unsuccessful and may benefit from a better understanding of the relative effects of two common treatment foci – decreased weight and increased volume of physical activity – on blood glucose. Overweight and obese adults (N = 59; Mage = 60 years) with hemoglobin A1c (HbA1c) values consistent with diabetes participated in a 6-month community-based behavioral treatment based on tenets of self-efficacy theory and social cognitive theory. The treatment was associated with significantly increased physical activity, reduced body mass index (BMI), and reduced HbA1c levels (ps < .001). Changes in BMI and physical activity accounted for a significant portion of the variance in change in HbA1c, R2 = .13, p = .023. Change in volume of physical activity, β = ?.36, p = .007, but not change in BMI, β = ?.03, p = .792, significantly contributed to the variance in HbA1c change that was accounted for. There was no effect based on the sex of participants. Discussion focused on how findings might impact the efficacy, efficiency, and application of behavioral treatments for diabetes management.  相似文献

The Experiences in Close Relationships Scale – Revised Child version (ECR-RC; Brenning, Soenens, Braet, & Bosmans, 2011a) is a valuable tool for measuring anxious and avoidant attachment to parents in middle childhood and adolescence. However, given its substantial length, the present study aimed to develop an abridged ECR-RC. Four separate samples were used to attain this goal. First (Sample 1, N = 1880; M = 12 years), item selection resulted in a 12-item version, comprising six items for attachment anxiety and six items for attachment avoidance. Next, psychometric properties of this brief ECR-RC were investigated in Sample 1 and cross-validated in an older sample (Sample 2, N = 310; M = 16 years) and in a clinical sample (Sample 3, N = 99; M = 14 years). In all three samples, comparison of the full and reduced ECR-RC revealed similar psychometric properties. In a final sample (Sample 4, N = 110; M = 18 years), we assessed reliability, factor structure and validity when administering the 12-item ECR-RC as a stand-alone instrument. In conclusion, the brief ECR-RC showed excellent reliability and validity.  相似文献

BackgroundIt is well established that both aerobic physical activity (PA) and resistance training are essential in the treatment and management of type 2 diabetes (T2D), but few studies have examined the determinants of both modes of PA in the same sample.PurposeThe main objective was to investigate the utility of the Protection Motivation Theory (PMT) in predicting aerobic PA and resistance training in a population sample of T2D adults.MethodsA total of 244 individuals completed self-report PMT constructs of vulnerability, severity, fear, response efficacy, self-efficacy and intention, and a 3-month follow-up that assessed aerobic PA and resistance training.ResultsPMT explained 19% (p < .001) and 20% (p < .001) of the variance respectively for aerobic PA and resistance training behaviour. Significant associations were found between self-efficacy (β = 0.45, p < .001) and gender (β = 0.15, p < .05) for aerobic PA, and self-efficacy (β = 0.48, p < .001) and age (β = 0.17, p < .05) for resistance training. PMT accounted for 43% (p < .001) and 56% (p < .001) of the variance respectively for aerobic PA and resistance training intentions. For aerobic PA, response efficacy (β = 0.14, p < .05) and self-efficacy (β = 0.59, p < .001) were significantly associated with intention, while response efficacy (β = 0.23, p < .001), self-efficacy (β = 0.64, p < .001) and age (β = 0.10, p < .05) were significantly related with resistance training intention.ConclusionsNone of the unique constructs of the PMT (i.e., perceived vulnerability, severity and fear) were significant with either aerobic and resistance training intention. These results may guide the development of effective PA interventions in people with T2D.  相似文献

The ability to locate and orient ourselves with respect to environmental space is known as sense of direction (“SOD”). While there is considerable evidence for the predictive utility of self-report measures of this psychological construct, relatively little research has investigated the psychometric properties of the self-report scale by which it is most commonly measured – the Santa Barbara Sense of Direction scale (SBSOD, Hegarty et al., 2002) – or the broader personality correlates. The present study evaluated the factor structure of the SBSOD following administration to 12,155 individuals and situated it among prominent sources of individual differences, specifically the Big Five personality traits and intelligence. Findings suggest that the SBSOD scale has relatively high general factor saturation, and that a considerable portion of the variance in SBSOD scores is explained by other personality traits, including Conscientiousness (r = 0.33), Intellect (r = 0.27), Emotional Stability (r = 0.26), and Extraversion (r = 0.23). Cognitive ability was less highly correlated with SBSOD scores when measured at the level of general intelligence (r = 0.11) and in terms of mental rotation ability (r = .07). Recommendations are given for revision of the SBSOD scale based on item-level analyses.  相似文献

Patients with Parkinson’s disease (PD) typically suffer from an asymmetric degeneration of dopaminergic cells in the substantia nigra, resulting in right-sided (RPD) or left-sided (LPD) predominance of motor symptomatology. As the dopaminergic system is also involved in attention, we examined horizontal and vertical orienting of attention in LPD (N = 10), RPD (N = 9) and controls (N = 10). Four LPD patients demonstrated left neglect and three LPD patients demonstrated neglect for the upper visual field. LPD patients demonstrated a slower performance in detecting targets in the left hemifield and did not demonstrate a validity effect, unlike RPD patients and controls. RPD patients performed similar to controls, with the exception of one patient showing left and another showing right neglect, and two RPD patients demonstrated lower neglect. In sum, horizontal and vertical orienting of attention can be affected in Parkinson’s disease – particularly in LPD – from very subtle slowing to clinically detectable horizontal and/or vertical neglect.  相似文献

The present study examined the importance of different sources of information for the development of children's self-perceptions of early school-related ability. In a sample of German elementary school children (N = 595) it was demonstrated that the associations between pupils’ ability self-perceptions on the one hand and parents’ perception of their children's ability, pupils’ intelligence and teacher-rated school achievement on the other increased throughout elementary school. In a second step, commonality analyses were employed in two subsamples (N = 416 and N = 145) to partition variance in children's self-perceptions that was specifically explained by either teacher-rated school achievement or parents’ perceptions, or by both variables. The results support the assumption that the importance of teacher evaluations for children's ability self-perceptions increases while the importance of parents’ perceptions decreases during the early school years.  相似文献

Sensory dysfunctions may underlie key characteristics in children with Autism Spectrum Disorders (ASD). The current study aimed to investigate auditory change detection in children with ASD in order to determine event-related potentials to meaningless and meaningful speech stimuli. 11 high functioning boys with a diagnosis of autism spectrum disorders (mean age = 13.0; SD = 1.08) and 11 typically developing boys (mean age = 13.7; SD = 1.5) participated in a mismatch negativity (MMN) paradigm. Results revealed that compared to TD controls, the children with ASD showed significantly reduced MMN responses to both words and pseudowords in the frontal regions of the brain and also a significant reduction in their activation for words in the Central Parietal regions. In order to test the relationship between sensory processing and auditory processing, children completed the Adult and Adolescent Sensory Profile. As predicted, the children with ASD showed more extreme sensory behaviours and were significantly higher than their typically developing controls across three of the sensory quadrants (sensory sensitivity, low registration and sensory avoidance). Importantly, only auditory sensory sensitivity was able to account for the differences displayed for words in the frontal and central parietal regions when controlling for the effect of group, revealing an inverse relationship of the higher sensory sensitivity scores the less activation in response for words. We discuss how the expression of sensory behaviours in ASD may result in deficient neurophysiological mechanisms underlying automatic language processing.  相似文献

The scarcity of women in ICT-related studies has been systematically reported by the scientific community for many years. This paper has three goals: to analyze gender differences in self-concept of computer and math abilities along with math performance in two consecutive academic years; to study the ontogeny of gender differences in self-concept of computer and of math abilities and math performance across subject areas; and to contrast the role these variables play in predicting ICT-related studies over 2 years. 900 (M = 15 years, s.d. = 1.73) and 424 (M = 16 years, s.d. = .49) Spanish secondary students participated at both times. Self-concept of computer ability is higher in boys at both times; furthermore it decreases in girls and increases in boys across time. At time 2, boys have a higher self-concept of math ability, despite the lack of gender differences in math performance. Participants have a higher self-concept of math ability and math performance at time 1 than at time 2. Self-concepts of computer ability predict the intention to pursue ICT-related studies and mediate the association of gender with the intention to pursue ICT-studies.  相似文献

The current study investigated the influence of Machiavellianism, a personality trait characterized by a manipulative interpersonal style and willingness to exploit others (Christie & Geis, 1970), on three areas of sexual behavior. Men (N = 90) and women (N = 192) aged 18–81 years (M = 25.82, SD = 9.85) completed the Mach IV (Christie & Geis, 1970), YSEX Questionnaire (Meston & Buss, 2007), Sexual Deception Scale (Marelich, Lundquist, Painter, & Mechanic, 2008) and Intentions Towards Infidelity Scale (Jones, Olderbak, & Figueredo, 2011). Those with high levels of Machiavellianism were more likely to engage in sexual behavior for physical reasons, goal attainment and insecurity. In particular, Machiavellian men and women endorsed stress reduction, experience seeking, resources, social status, revenge, utilitarian reasons, boosting self-esteem, duty/pressure, and mate guarding as motivations for sexual behavior. Machiavellianism was also a significant predictor of each form of sexual deception investigated (blatant lying, self-serving and avoiding confrontation) and intentions to engage in infidelity. Sex did not moderate the influence of Machiavellianism on sexual behavior.  相似文献

Mood-repair conceptualizations of procrastination suggest that regulation of immediate mood is prioritized over instrumental action towards goals. The aim of the current research was to examine how and why absorption – a mindset reflecting a responsiveness to engaging stimuli – may account for procrastinators’ tendency to focus on immediately rewarding activities at the cost of their long term goals, and the cognitive implications of being absorbed in the moment. Across two student samples (Study 1: N = 103; Study 2: N = 339) procrastination was associated with absorption. A bootstrapping analysis of the indirect effects of procrastination on absorption through state anxiety in Study 1 was significant supporting the hypothesized role of absorption as a vulnerability towards mood-regulating distractions for procrastinators. In Study 2 small but significant indirect effects of procrastination on cognitive failures through absorption emerged, supporting the proposition that absorption may have a cognitive toll for procrastinators. Taken together, these findings suggest a cognitive escape hypothesis to explain how procrastinators deal with negative moods, and provides new insights into the factors and processes that contribute to the self-regulation difficulties that characterize trait procrastination.  相似文献

Set-shifting is essential to cognitive flexibility and relies on frontal lobe function. Previous studies have mostly focused on feedback processes following shifting rather than set-shifting itself. We designed an MEG paradigm without feedback to directly investigate the neural correlates of set-shifting. Adults (n = 16) matched one of two coloured images with a third stimulus, the target, by either the colour or shape dimension of the target. Half of the shift trials involved colour-to-colour or shape-to-shape (intra-dimensional: ID) shifting and the other half involved colour-to-shape or shape-to-colour (extra-dimensional: ED) shifting. MEG was continuously recorded on a 151 channel CTF system. We used beamforming to analyze responses to the first (shift) and the third (repeat) trials in each set. These trials were contrasted separately for ID and ED sets. Shift versus repeat trials showed larger MEG activations for intra-dimensional shifting in the right inferior frontal gyrus (BA 47), left medial frontal gyrus (BA 10) and right superior frontal gyrus (BA 9) as early as 100 ms, and in left middle frontal gyrus (BA 11) between 250–500 ms. Activations related to extra-dimensional shifting were detected in left inferior frontal gyrus (BA 44), left middle frontal gyrus (BA 11), and right middle frontal gyrus (BA 46) between 100 ms and 350 ms, followed by superior frontal gyrus (BA 8/BA 10) between 250–500 ms. Intra-dimensional and extra-dimensional shifting also activated bilateral and right parietal areas, respectively. This study establishes the location and timing of frontal and parietal activations during an intra-dimensional versus extra-dimensional shifting task.  相似文献

Young children sometimes make serious attempts to perform impossible actions on miniature objects as if they were full-size objects. The existing explanations of these curious action errors assume (but never explicitly tested) children's decreased attention to object size information. This study investigated the attention to object size information in scale errors performers. Two groups of children aged 18–25 months (N = 52) and 48–60 months (N = 23) were tested in two consecutive tasks: an action task that replicated the original scale errors elicitation situation, and a looking task that involved watching on a computer screen actions performed with adequate to inadequate size object. Our key finding – that children performing scale errors in the action task subsequently pay less attention to size changes than non-scale errors performers in the looking task – suggests that the origins of scale errors in childhood operate already at the perceptual level, and not at the action level.  相似文献

Research on personality and adiposity has focused primarily on Western samples; less is known about the personality correlates of BMI in Asian populations. We examined the association between personality and body mass index (BMI) among community-dwelling Japanese adults (N = 380), Chinese adolescents (N = 5882), and a meta-analysis inclusive of a published Korean sample (total N = 10,304). In the new samples and meta-analysis, Extraversion and Agreeableness were associated with higher BMI among men. In contrast to what is often found in Western samples, Conscientiousness was mostly unrelated to adiposity. These findings link pro-social tendencies to overweight among Asian men; Conscientiousness may be less relevant for BMI in Eastern societies with a low prevalence of obesity and strong social norms for eating but not thinness.  相似文献

We used meta-analysis to test for gender differences in implicit needs for affiliation/intimacy, assessed via story-coding methods. We included thirty-three effect sizes from 26 publications and 2 unpublished studies, covering a total of 5962 research participants (58% female). Across studies, women scored higher than men in measures of implicit affiliation motivation (d1 = 0.45, 95%CI = [0.37; 0.53]). This finding was not moderated by the coding system used, gender congruence of the picture cues presented, or correction for protocol length. Men and women did not differ in their implicit needs for power (N = 2493, k = 15, d1 = −0.19, 95%CI = [−0.44; 0.05]) or achievement (N = 2235, k = 13, d1 = 0.14, 95%CI = [−0.03; 0.30]).  相似文献

The IPIP-NEO (Goldberg, 1999) is a 300-item inventory that measures constructs similar to those in the NEO Personality Inventory (NEO PI-R; Costa & McCrae, 1992). Despite evidence for its reliability and validity, the IPIP-NEO is even longer than the original 240-item NEO PI-R. This article details the development of a 120-item version of the IPIP-NEO from an Internet sample (N = 21,588) and the subsequent testing of its psychometric properties in Goldberg’s (2008) Eugene-Springfield community sample (N = 481), two additional large Internet samples (Ns = 307,313 and 619,150) and a local sample (N = 160). Results indicate that the psychometric properties of the 120-item IPIP-NEO compare favorably to the properties of the longer form.  相似文献
