Goal-setting and mental effort investment may be influenced by the perception of success or failure. The aim of the current
study was to investigate the dynamics of motivational intensity model using false performance feedback. Forty participants
performed a demanding cognitive task over five successive (5 min) blocks. Participants received performance feedback of either
progressive success or progressive failure. A number of psychophysiological variables were used to index mental effort investment
and emotion, including: HRV components, blood pressure, skin conductance level, EEG, and facial EMG. Subjective estimates
of mood, workload and motivation were also collected alongside performance measures. The success group experienced positive
affect and a less pronounced decline in subjective motivation in response to a perception of successful achievement. In contrast,
feedback of failure led to adverse changes in mood/motivation, but did not lead to the absolute withdrawal of effort, although
trends in the psychophysiological data suggest that participants in the failure group were on the verge of abandoning the
task. The implications of these findings are discussed within the context of goal-setting and effort regulation models. 相似文献

Female undergraduates were assigned to one of three groups, two involving regulatory training and one not. Training participants
performed for 2 weeks tasks that required strong behavioral restraint (Strong Training) or weak behavioral restraint (Weak
Training). Later, they took part in (1) a laboratory session in which they performed tasks with inhibitory components, and
(2) a follow-up week in which they provided health behavior reports and used designated dental supplies. No Training participants
took part only in the session and follow-up week. As expected, laboratory performance was improved for Strong- relative to
No Training participants, with performance for Weak Training participants falling in between. Also as expected, Strong Training
participants used more floss in the follow-up week than did the No Training participants, with floss for Weak Training participants
falling between. Contrary to expectation, Strong Training participants used less toothpaste and reported having brushed less
than the No Training participants. In addition, Strong Training participants evinced exaggerated—rather than diminished—cardiovascular
responses during the laboratory tasks. The performance and floss use data support the suggestion that inhibitory system strength
can be increased through use. The brushing and cardiovascular findings may be interpretable in inhibitory strength terms. 相似文献

Bimodal bilinguals are hearing individuals who know both a signed and a spoken language. Effects of bimodal bilingualism on behavior and brain organization are reviewed, and an fMRI investigation of the recognition of facial expressions by ASL-English bilinguals is reported. The fMRI results reveal separate effects of sign language and spoken language experience on activation patterns within the superior temporal sulcus. In addition, the strong left-lateralized activation for facial expression recognition previously observed for deaf signers was not observed for hearing signers. We conclude that both sign language experience and deafness can affect the neural organization for recognizing facial expressions, and we argue that bimodal bilinguals provide a unique window into the neurocognitive changes that occur with the acquisition of two languages. 相似文献

The professional literature diverges in defining the role of forgiveness and reconciliation in counseling regarding how forgiveness and reconciliation are conceptualized from a professional and secular perspective. The Jewish conceptualization of forgiveness is multifaceted; mechila, the forgiveness of debt, is particularly important in providing a framework for forgiveness when the issue of reconciliation is involved. The authors offer an explanation of the Jewish conceptualization of forgiveness and discuss a way to infuse the concept of mechila into counseling practice on a broader level with all clients. 相似文献

Our study examined the role of social identity processes in determining how individuals evaluate, deal with, and are affected by severe events of war. We reasoned that for those who experience such events collectively and who identify strongly with their group, primary appraisal will be filtered through the prism of social identity. In a sample of Kosovo Albanians who had survived the armed conflict in 1999, we found that those who were able to evaluate the war as affirming their group identity presented lower levels of depressive mood and anxiety and higher levels of self-efficacy. Furthermore, this process of war appraisal affected the process of secondary appraisal. Specifically, positive war appraisal increased availability of support from close others and reduced the importance of positive individual coping strategies in dealing with extreme events. Conversely, negative war appraisal reduced availability of support from close others and reduced the importance of negative coping strategies in dealing with extreme events. 相似文献

In this review, we describe neuropsychological and brain imaging findings in the early stages of psychosis and schizophrenia.
We focus on recent clinical high-risk studies and consider whether the evidence supports these as ‘endophenotypes’ of a vulnerability
to the illness or as ‘biomarkers’ of illness onset and transition. The findings suggest that there are a number of processes
at psychosis onset that may represent biomarkers of incipient illness. These neurobiological indices particularly implicate
the integrity of frontal and temporal cortices, which may or may not be related to the genetics of psychosis (i.e. potential
‘endophenotypes’). However, these brain regions are dynamically changing during normal maturation, meaning that any putative
neurobiological markers identified at the earliest stages of illness may be relatively unstable. We suggest that, while such
measures may be readily identified as potential neurobiological markers of established illness, they are inconsistent at (or
around) the time of illness onset when assessed cross-sectionally. Instead, identification of more valid risk markers may
require longitudinal assessment to ascertain normal or abnormal trajectories of neurodevelopment. Accordingly, we assert that
the current conceptualisations of potential biomarkers and/or ‘endophenotypes’ for schizophrenia may need to be reconsidered
in the context of normal and abnormal brain maturational processes at the time of onset of psychotic disorders. 相似文献

To determine if choroidal melanoma patients want cytogenetic prognostic information. Ninety-nine choroidal melanoma patients
completed a questionnaire regarding their opinions about receiving prognostic information. The perceived usefulness of prognostic
information was evaluated in patients who had undergone cytogenetic testing. Depressive symptoms, quality of life, and interest
in supportive counseling during test receipt were assessed. Ninety-seven percent of respondents reported that they would have
wanted prognostic information at the time of their treatment and 98% of respondents reported that supportive counseling should
be offered when prognostic information is given. Patients who had received a more favorable prognostic result were more likely
to endorse the usefulness of cytogenetic testing than were patients who had received a less favorable prognostic result. Psychological
status did not vary significantly as a function of cytogenetic test result. Prognostic information was important to patients
with choroidal melanoma, even in the absence of prophylactic measures which might improve prognosis. 相似文献

Encouraging consumers to engage in helpful behavior is a perennial task of marketers in non-profit and for-profit organizations. Recent research suggests that merely imagining the presence of others can lead to less helping behavior on a subsequent unrelated task (Garcia, S.M., Weaver, K.D., Moskowitz, G.B., and Darley, J.M. (2002). Crowded minds: The implicit bystander effect. Journal of Personality and Social Psychology, 83, 843–853.). The present analysis uncovers the boundary conditions of this effect. Across four studies, we establish that the degree to which a group situation fosters public scrutiny is an important moderator. When group primes are paired with public scrutiny, their inhibitive effect on helping behavior diminishes, and helping behavior on a subsequent task tends to increase. The present research thus adds complexity to previous findings by suggesting that implicit bystanders can both decrease and increase helping behavior. 相似文献

Research on dynamic decision-making tasks, in which the payoffs associated with each choice vary with participants’ recent
choice history, shows that humans have difficulty making long-term optimal choices in the presence of attractive immediate
rewards. However, a number of recent studies have shown that simple cues providing information about the underlying state
of the task environment may facilitate optimal responding. In this study, we examined the mechanism by which this state knowledge
influences choice behavior. We examined the possibility that participants use state information in conjunction with changing
payoffs to extrapolate payoffs in future states. We found support for this hypothesis in an experiment in which generalizations
based on this state information worked to the benefit or detriment of task performance, depending on the task’s payoff structure. 相似文献
