Affective processing is one domain that remains relatively intact in healthy aging. Investigations into the neural responses associated with reward anticipation have revealed that older and younger adults recruit the same midbrain reward regions, but other evidence suggests this recruitment may differ depending on the valence (gain, loss) of the incentive cue. The goal of the current study was to examine functional covariance during gain and loss feedback in younger and healthy older adults. A group of 15 older adults (mean age = 68.5) and 16 younger adults (mean age = 25.4) completed a revised Monetary Incentive Delay task (rMID; Knutson, Westdorp, Kaiser, &; Hommer, 2000) while in the fMRI scanner. The rMID is a reaction time task where successful performance, either gaining a reward or avoiding a loss, is defined by hitting a button during the brief presentation of a visual target. Participants receive gain and loss anticipation cues before each trial and feedback after each trial with four possible outcomes: +$5.00, +0.00, -$5.00, and -Affective processing is one domain that remains relatively intact in healthy aging.

Participants receive gain and loss anticipation cues before each trial and feedback after each trial with four possible outcomes: +$5.00, +0.00, -$5.00, and -$0.00. Using seed-voxel partial least squares analyses, with seed voxels in the caudate and ventromedial prefrontal cortex, whole-brain functional covariance revealed that younger and older adults engage the same network of regions to support general feedback processing. However, older adults engaged two additional networks to support processing of negative feedback, gain_miss (+0), loss_miss (-$5), and loss_hit (?0), specifically. These findings are in line with theories of a positivity effect in aging and may have implications for reward-stimulus learning and decision making following performance-contingent negative feedback.  相似文献

In the current set of experiments, we establish, and explore the consequences of, the imprecision that characterizes the attribute response labels typically employed in the Implicit Association Test (IAT). In Experiment 1, we demonstrate the malleability of the IAT, as conventionally implemented. IAT scores are shown to be influenced by perspective mindsets induced by an unrelated preceding task. Then, we explore how the malleability of the IAT can lead to the inference that attitude change has occurred even when there is very good reason to believe it has not (Experiment 2), and conversely, how it can obscure the detection of attitude change when such change is indeed likely to have occurred (Experiment 3). We provide conceptual explanations for these discrepancies and suggest methodological improvements to enhance the specificity of IAT measures.  相似文献

Few studies have been published on the attitudes of people with physical disabilities toward genetic counseling and prenatal diagnosis. Articles in the lay press and social science literature on this topic, mainly written by disability rights activists and advocates, imply opposition to prenatal diagnosis and the field of clinical genetics by the physically disabled population. In this study, 15 adults with physical disabilities were interviewed regarding their attitudes toward genetic counseling and prenatal diagnosis. Genetic counseling and prenatal diagnosis were generally viewed favorably by this sample of the disability community. Only a small percentage of the sample perceived genetics to be eugenic. Implications for genetic counseling and future research are discussed.  相似文献

Using longitudinal data collected at four time points from 191 dyads of Mexican‐origin adolescent first‐time mothers and their mother figures, we examined changes in and socialization of traditional gender role attitudes across the transition to parenthood using latent growth curve modeling and actor – partner interdependence modeling. Longitudinal growth models indicated that, regardless of nativity status, adolescent mothers' and their foreign‐born mother figures' gender role attitudes became more egalitarian across adolescents' transition to parenthood, spanning from the 3rd trimester of pregnancy to 36 months postpartum. Furthermore, actor‐partner interdependence modeling suggested that adolescents' and their mother figures' gender role attitudes during adolescents' third trimester of pregnancy equally contributed to subsequent increases in one another's gender role attitudes at 10 months postpartum. Importantly, this reciprocal socialization process was not moderated by adolescent mothers' nor by their mother figures' nativity status. Findings suggest that it is important to understand the cultural and intergenerational family processes that contribute to the development of gender role attitudes during the transition to parenthood for adolescent mothers and their mother figures in Mexican‐origin families.  相似文献

This study examines the effect of leader moral development on the organization’s ethical climate and employee attitudes. Results indicate that the relationship between leader moral development and ethical climate is moderated by two factors: the extent to which the leader utilizes his or her cognitive moral development (i.e., capacity for ethical reasoning), and the age of the organization. Specifically, the influence of the leader’s moral development was stronger for high utilizing leaders, those whose moral actions were consistent with their moral reasoning. Additionally, the influence of the leader’s moral development was stronger in younger organizations. Finally, as predicted, congruence between the leader’s moral development and the employee’s moral development was positively associated with job satisfaction and organizational commitment and negatively associated with turnover intentions.  相似文献

Studies have shown the existence of inter-individual differences in choice behavior, some people seeking for the best (maximizers) and others for a good enough option (satisficers). Here, we explored whether these inter-individual differences are influenced by aging and common personality traits (i.e., Big Five model). Young (n = 125; 19 years old) and elderly adults (n = 101; 86 years old) completed different scales assessing – among others – maximization and Big Five traits. Our results indicated a greater proportion of maximizers in elderly than in young adults. We also found a minor association between maximization and Big Five traits in both groups. In sum, aging influences choice behavior, but this cannot be explained by changes of common personality traits.  相似文献

BackgroundTheories relating to young children’s social cognitive maturity and their prevailing social groups play important roles in the acquisition of attitudes. Previous research has shown that preschool and kindergarten children’s stuttering attitudes are characterized by stronger negative beliefs and self reactions than those of parents. By contrast, 12 year-old children’s stuttering attitudes have been shown to be similar to their parents’ attitudes. Other research indicates that parental stuttering attitudes are no different from attitudes of adults who are not parents.PurposeThe purpose of this study was to explore children’s stuttering attitudes of preschool through 5th grade children and to compare them to their parents’ attitudes.MethodChildren and parents from a rural Appalachian elementary school and child/parent pairs from other areas in the region responded to child and adult versions of the Public Opinion Survey of Human Attributes–Stuttering (POSHA–S/Child and POSHA–S). Seven grade levels were included: preschool, kindergarten, 1st grade, 2nd grade, 3rd grade, 4th grade, and 5th grade.ResultsConfirming earlier research, younger children’s attitudes toward stuttering were considerably less positive than those of their parents. As children matured up to the fifth grade, however, their stuttering attitudes progressively were more positive. Parents’ stuttering attitudes were quite consistent across all seven grade levels.ConclusionsConsistent with theories of attitudinal development, between the ages of 4 and 11 years, children’s measured attitudes toward stuttering improved and gradually approximated the attitudes of their parents and the general public.  相似文献

The effects of age on the ability to resolve perceptual ambiguity are unknown, though it depends on frontoparietal attentional networks known to change with age. We presented the bistable Necker cube to 24 middle-aged and OAs (older adults; 56–78 years) and 20 YAs (younger adults; 18–24 years) under passive-viewing and volitional control conditions: Hold one cube percept and Switch between cube percepts. During passive viewing, OAs had longer dominance durations (time spent on each percept) than YAs. In the Hold condition, OAs were less able than YAs to increase dominance durations. In the Switch condition, OAs and YAs did not differ in performance. Dominance durations in either condition correlated with performance on tests of executive function mediated by the frontal lobes. Eye movements (fixation deviations) did not differ between groups. These results suggest that OAs’ reduced ability to hold a percept may arise from reduced selective attention. The lack of correlation of performance between Hold and executive-function measures suggests at least a partial segregation of underlying mechanisms.  相似文献

Although factors shaping sibling relationships and the developmental dynamics of such consanguinity have been addressed by various scholars, investigations questioning how the risky behaviors of one sibling, specifically substance abuse, may impact brothers versus sisters are few. The current study explored non–substance-abusing siblings’ reports of their mood, attitudes, feelings of social support, and emotions if one of their brothers or sisters was perceived to be a substance abuser. Surprisingly, 22% of a college-aged convenience sample (N = 312) described one or more of their siblings as a substance abuser and reported being exposed to drugs at an earlier age than their non–substance-abusing counterparts, in addition to other differences. Sisters, more than brothers, were also affected. These exploratory findings, although limited by potential sampling bias, highlight potential areas for future research that could clarify and perhaps improve the experience of the “forgotten” siblings in a risky family constellation.  相似文献

The present study examined the relationship between religion and well-being in older adults during a time of financial difficulty within their religious community. Focus-group and one-on-one interviews were carried out with 39 participants sampled from three Anglican parishes in eastern Canada during a financial crisis that was likely to lead to the closing of two churches. Three main themes emerged from the analyses: Crisis, Transition, and Status Quo. The financial situation was discussed as a crisis; other issues were viewed as opportunities for transition, and personal faith was perceived as being stable and constant. The results of the present study suggest that for older adults, the more internal and faith-based aspects of religiosity have a stronger impact on well-being than do changes that revolve around the external or religious aspects of church participation.  相似文献
