Counterfactual information processing refers to the consideration of events that did not occur in comparison to those actually experienced, in order to determine optimal actions, and can be formulated as computational learning signals, referred to as fictive prediction errors. Decision making and the neural circuitry for counterfactual processing are altered in healthy elderly adults. This experiment investigated age differences in neural systems for decision making with knowledge of counterfactual outcomes. Two groups of healthy adult participants, young (N = 30; ages 19–30 years) and elderly (N = 19; ages 65–80 years), were scanned with fMRI during 240 trials of a strategic sequential investment task in which a particular strategy of differentially weighting counterfactual gains and losses during valuation is associated with more optimal performance. Elderly participants earned significantly less than young adults, differently weighted counterfactual consequences and exploited task knowledge, and exhibited altered activity in a fronto-striatal circuit while making choices, compared to young adults. The degree to which task knowledge was exploited was positively correlated with modulation of neural activity by expected value in the vmPFC for young adults, but not in the elderly. These findings demonstrate that elderly participants’ poor task performance may be related to different counterfactual processing.  相似文献

This article presents VQone, a graphical experiment builder, written as a MATLAB toolbox, developed for image and video quality ratings. VQone contains the main elements needed for the subjective image and video quality rating process. This includes building and conducting experiments and data analysis. All functions can be controlled through graphical user interfaces. The experiment builder includes many standardized image and video quality rating methods. Moreover, it enables the creation of new methods or modified versions from standard methods. VQone is distributed free of charge under the terms of the GNU general public license and allows code modifications to be made so that the program’s functions can be adjusted according to a user’s requirements. VQone is available for download from the project page (http://www.helsinki.fi/psychology/groups/visualcognition/).  相似文献

This article reports the construction and validation of a comprehensive self-report measure of fantasy. Unlike previous measures of fantasy, which focus on psychopathology, we conceive fantasy as a trait with positive connotation. Principal component analysis (N = 318) and confirmatory factor analyses (N = 345) were conducted using 2 sociodemographically diverse samples. The results provided support for a 2-factor conceptualization of the construct, with the dimensions imaginative fantasy and creative fantasy. Imaginative fantasy refers to vivid imagination and absorption in these images and daydreams. Creative fantasy refers to the activity of using fantasy to create new ideas. The trait measure showed good internal consistency, test–retest reliability, discriminant and convergent construct validity, as well as incremental validity. Moreover, in 3 behavioral studies, we put fantasy scores in relationship with behavioral data to provide further proof of validity. A comprehensive measure of fantasy can contribute to our understanding of individual differences in inner experiences, creative processes, and problem solving.  相似文献

This article discusses how the neo‐Pentecostal concept of power evangelism, read from a liberation perspective, might be useful to contextualize evangelism in the Toba Batak region of Samosir. In a situation where evangelistic preaching follows an evangelical forensic paradigm but Christians turn to traditional religious rituals for blessing, healing, and protection, a new approach is needed. Preaching and liturgies informed by a power paradigm might resolve the problem of syncretism, but important theological questions need to be clarified.  相似文献

The present study was designed to examine whether parents’ views of their child’s academic competencies are structured by gendered conceptions of abilities. In a longitudinal research design, a group of parents (N = 391) were asked to assess their third-grade child’s competence in mathematics and Finnish and to respond to a set of attitude statements; when the child reached the fifth grade, the parents were asked to reassess his/her competencies. It was found that the influence of the gender stereotype was partly domain-specific: The stereotype concerning Finnish organized the parental competence assessments as early as the child’s third grade and also predicted the assessments made about the child over the next two grades, whereas the stereotype concerning mathematics only predicted the assessments made as late as the fifth grade. In the Finnish competence assessments, the gender stereotype moderated the overall gender-of-the-child effect, whereas in the mathematics competence assessments, the gender-of-the-child effect was evinced only by the parent group that endorsed the gender stereotype. Culture-bound gender expectations and attitudes toward the expectations are significant, then, for parents’ assessments of their child’s competencies as early as the elementary school years.  相似文献

The left cradling preference refers to the finding that women hold their infants more frequently on the left side of their own bodies. Several observational studies showed reduced left cradling during stressful circumstances, such as mother-infant separation, or domestic violence. However, until now no experimental study was conducted to investigate the immediate impact of stress on cradling behaviour. Half of the 64 female subjects participating were randomly assigned to a stressful bilateral cold pressor test. The remaining subjects performed a non-stressful control procedure. Before and after this intervention, cradling behaviour was assessed using a baby-like doll. Subjects showed a left cradling preference prior to the intervention. The cold pressor test increased blood pressure and heart rate significantly. A repeated ANOVA revealed an interaction of intervention (cold pressor vs. control) X assessment period (pre- vs. post-intervention), indicating that cold pressor stress reduces left cradling behaviour in female volunteers. Our data indicate that stress influences cradling preference. This may be of relevance for caregiver-infant interactions.  相似文献

It was hypothesized that subjects with medical symptoms would show more signs of stress in projective drawings. A Stress Load Index, including five signs of stress in drawings, was evaluated. A questionnaire with an instruction to draw "a person in the rain" was sent to a cohort of 195 subjects, and the drawings were analysed blindly for eight stress items. Men had a higher index than women (p < .05) and drew clouds more often (p < .05). Drawing of clouds was associated with headache (adjOR = 4.28; 95% CI 1.75; 11.68). Drawing of puddles was associated with ocular symptoms (adjOR = 3.22; 95% CI 1.38, 7.50), facial dermal symptoms (adjOR= 2.94; 95% CI 1.28, 6.81), and tiredness (adjOR = 2.44; 95% CI 1.05, 5.67). Drawing of long rain strokes was associated with nasal symptoms (adjOR = 2.28; 95% CI 1.05, 2.06) and headache (adjOR = 3.20; 95% CI 1.28, 8.05). Age and stress load were predictors of sick building syndrome symptoms (p < .05). In conclusion, a nonverbal projective drawing test detected sex differences which represent directions opposite to those with verbal methods. These need empirical assessment.  相似文献

In this study we argue that predictions of the impact of group status, status stability and status legitimacy on intergroup attitudes can be refined using the subjective perceptions of various dimensions of ingroup vitality. We tested the main and moderating effects of perceived present, future and the legitimacy of present ingroup vitality and perceived discrimination on intergroup attitudes in a nation-wide probability sample (N= 1,411) of Swedish-speaking Finns, controlling for ingroup identification. We found that those who perceived the legitimacy of present ingroup vitality to be low had more negative intergroup attitudes than those who perceived the legitimacy to be high. Perceived present and future ingroup vitality had no main effects on the dependent variable. Instead, perceived future ingroup vitality moderated the effect of perceived discrimination on intergroup attitudes. In addition, the perceived legitimacy of present ingroup vitality mediated the effect of perceived present ingroup vitality on intergroup attitudes.  相似文献

In this case study, we examined how variations of the camera perspective affect adults' assessment of veracity in a real‐life high‐stake situation; a masked male confessing to a very serious crime. The interview, conducted by one of Sweden's most awarded journalists, lasted 30 minutes and consisted of over 100 detailed questions about the crime. The interview was videotaped simultaneously by three cameras positioned at different locations, each taking a unique visual perspective. One camera focused on the suspect only, one on the interviewer only, and one equally on the suspect and the interviewer. Each videotape was shown to 32 adult observers (N = 96) who were asked to assess the suspect's veracity and to report subjective cues justifying their veracity assessment. The results confirmed the camera perspective bias, by showing that the observers in the ‘suspect only’ condition assessed the confession as significantly more reliable than did the observers in the ‘interviewer only’ condition. The observers reported that they relied heavily on verbal cues when assessing the confession, and particularly regarding confidence and consistency. Copyright © 2008 John Wiley & Sons, Ltd.  相似文献

To investigate preferential processing of emotional scenes competing for limited attentional resources with neutral scenes, prime pictures were presented briefly (450 ms), peripherally (5.2° away from fixation), and simultaneously (one emotional and one neutral scene) versus singly. Primes were followed by a mask and a probe for recognition. Hit rate was higher for emotional than for neutral scenes in the dual- but not in the single-prime condition, and A' sensitivity decreased for neutral but not for emotional scenes in the dual-prime condition. This preferential processing involved both selective orienting and efficient encoding, as revealed, respectively, by a higher probability of first fixation on—and shorter saccade latencies to—emotional scenes and by shorter fixation time needed to accurately identify emotional scenes, in comparison with neutral scenes.  相似文献
