Decision-making research has thoroughly investigated how people choose from a set of externally provided options. However, in ill-structured real-world environments, possible options for action are not defined by the situation but have to be generated by the agent. Here, we apply behavioral analysis (Study 1) and functional magnetic resonance imaging (Study 2) to investigate option generation and subsequent choice. For this purpose, we employ a new experimental task that requires participants to generate options for simple real-world scenarios and to subsequently decide among the generated options. Correlational analysis with a cognitive test battery suggests that retrieval of options from long-term memory is a relevant process during option generation. The results of the fMRI study demonstrate that option generation in simple real-world scenarios recruits the anterior prefrontal cortex. Furthermore, we show that choice behavior and its neural correlates differ between self-generated and externally provided options. Specifically, choice between self-generated options is associated with stronger recruitment of the dorsal anterior cingulate cortex. This impact of option generation on subsequent choice underlines the need for an expanded model of decision making to accommodate choice between self-generated options. 相似文献

The human face is a visual pattern of great social and biological importance. While previous studies have shown that attention may be preferentially directed and engaged longer by faces, the current study presents a new methodology to test the notion that faces can capture attention. The present study uses the occurrence of inhibition of return (IOR) as a diagnostic tool to determine the allocation of attention in visual space. Because previous research suggested that IOR at a location in space only occurs after attention has been reflexively moved to that location, the current finding of IOR at the location of the face provides converging support for the claim that faces do have the ability to summon attention. 相似文献

Mattes, UIrich, and Miller (1997) found that as response probability decreases in a simple reaction time (RT) task, participants produce more forceful responses as well as longer RTs, suggesting a direct influence of preparatory processes on the motor system. In this previous study, however, response probability was confounded with stimulus probability, leaving open the possibility that response force was sensitive to stimulus- rather than response-related preparation. The present study was conducted to unravel the effects of stimulus and response probability. Experiment 1 manipulated stimulus probability and revealed that responses to a more probable stimulus are less forceful than responses to a less probable stimulus even when both stimuli require the same response. Experiment 2 demonstrated that this stimulus probability effect does not depend on the overall level of response probability. Experiment 3 showed an analogous effect for response probability when stimulus probability is kept constant. The complete pattern of results suggests that both stimulus probability and response probability affect the forcefulness of a response. It is argued that response probability exerts adirect influence on the motor system, whereas stimulus probability influences the motor system indirectly via premotoric adjustments. 相似文献

Studies have highlighted the impact of ego-consciousness, religiosity and spirituality on psychotic symptoms, although so far no study has investigated if and how these factors may be interrelated. In this exploratory cross-sectional study, involving 42 patients with a diagnosis of acute paranoid schizophrenia (DSM-IV), we assessed religiosity (Religious Orientation Test) spirituality (Spiritual Transcendence Scale) and ego-pathology (Ego Pathology Inventory) and analysed any relationship with these and psychopathological symptoms (Positive and Negative Symptom Scale). The subjects were divided into four ethnic groups (Caucasian, Afro-Caribbean, African, and Asian) and a structured, qualitative interview on religious needs and self-concepts was also conducted. Using a multivariate analysis, we found statistically significant negative associations between the scores on ego and common pathology and religiosity and spirituality as covariates. This was seen across all ethnic groups. The findings are discussed in respect of the potential clinical importance of ethnic, religious and spiritual factors for assessment and management of patients with schizophrenia. 相似文献

Abstract Surgery can be regarded as a major stressor for any patient. High preoperative emotional arousal may negatively influence adjustment during surgery as well as the postoperative recovery rate. Consequently, the strategies individuals employ for coping with this stress are of prime importance for the quality of their adaptation. This paper reports the construction and empirical assessment of a new instrument for measuring strategies employed to cope with surgical stress. Factor analysis of this instrument, the Coping with Surgical Stress Scale (COSS), yielded five factors: Rumination, Optimism and Trust, Turning to Social and Religious Resources, Threat Avoidance, and Information Seeking. Internal consistencies of the corresponding subscales were satisfactory. Results concerning external relationships of the COSS with dispositional coping, state and trait anxiety, and indicators of perioperative adjustment showed that the COSS is a useful instrument for measuring surgery-related coping. 相似文献

Cognitive behavioral therapy is an effective treatment for virtually all psychiatric disorders. However, very few patients have access to it and few therapists are trained in the theory and practice of cognitive behavioral therapy. Based on the existing evidence and the articles of this series, the following recommendations are made: (a) all mental health care providers (including Psy.D. and social workers) need to be trained in the practice and theories of empirically supported treatments, specifically cognitive behavioral therapy; (b) clinical practice also needs to be based on theory, not just treatment manuals; and (c) psychological treatments have to move beyond the DSM boundaries. 相似文献

As it has been demonstrated that subliminal advertising can affect consumers' decisions – if the ad is goal relevant – the question rises whether consumers are able to shield themselves from subliminal influences. In the present research it was examined whether warning people of the presence of subliminal ads could decrease subliminal advertising effects. In Study 1, it was demonstrated that warning people of subliminal ads indeed diminished priming effects on consumer choice, whereas subliminal advertising effects were replicated for people who were not warned (i.e., people for whom the primed brand was goal relevant were more likely to select it when primed). Study 2 extended these findings, revealing that both participants warned before and after the priming manipulation were less influenced by subliminal brand primes than controls. This suggests that the warning does not decrease participants' sensitivity to the prime, but instead affects the influence of the prime at the behavioral level. Several explanations and implications are discussed. 相似文献

Prior studies have consistently found a surprising inaccuracy of people's neuroticism judgments at zero acquaintance. Based on the Realistic Accuracy Model (Funder, 1995), we hypothesize that this is due to a lack of relevance of the situation in which targets are typically observed. Fifty participants were videotaped in a highly trait‐relevant (i.e., socially stressful) situation as well as three less relevant situations. An aggregate of self‐reports and informant reports was used as the accuracy criterion. Four independent groups of unacquainted observers judged participants' neuroticism based on these short video sequences. Results showed that neuroticism judgments were significantly more accurate for the most trait‐relevant situation compared with the other three situations. This finding can be explained using lens model analyses: Only in the most relevant situation did neuroticism predict both visual nervousness and vocal nervousness, both of which in turn predicted neuroticism judgments by lay observers. Our findings show that strangers are sensitive to interindividual differences in neuroticism as long as targets are observed in a trait‐relevant situation. 相似文献

In recent years, a growing number of researchers have examined the watching eyes phenomenon (i.e., increased prosocial and decreased antisocial behavior when subtle watching eyes are present in the environment). Somewhat surprisingly, the questions of how and under what conditions subtle cues of being watched operate have been unanswered so far. The present contribution addresses this research gap. In two studies, we document that (a) subtle cues of being watched induce a sense of being seen and (b) chronic public self‐awareness moderates the watching eyes phenomenon in that specifically individuals with strong chronic public self‐awareness show more prosocial behavior under conditions of watching eyes. The applicability of subtle cues of being watched in research on social presence is discussed. 相似文献
