What are creative people like? Openness to experience is important to creativity, but little is known about plasticity, the higher-order factor that subsumes openness. College students (n = 189) completed measures of the Big Five and measures of creative cognition (fluency and quality of divergent thinking), everyday creative behaviors, creative achievement, and self-rated creativity. Latent variable models found broad effects of openness to experience and few effects of the other four domains. At the higher-order level, plasticity predicted higher scores on nearly all of the facets of creativity, and stability had several significant effects. For some creativity measures, plasticity and stability had opposing effects. Tests of latent interactions found no significant effects: plasticity and stability predict creatively independently, not jointly. 相似文献

Two chronic, nonfluent aphasia patients participated in overt naming fMRI scans, pre- and post-a series of repetitive transcranial magnetic stimulation (rTMS) treatments as part of a TMS study to improve naming. Each patient received 10, 1-Hz rTMS treatments to suppress a part of R pars triangularis. P1 was a ‘good responder’ with improved naming and phrase length; P2 was a ‘poor responder’ without improved naming.Pre-TMS (10 years poststroke), P1 had significant activation in R and L sensorimotor cortex, R IFG, and in both L and R SMA during overt naming fMRI (28% pictures named). At 3 mo. post-TMS (42% named), P1 showed continued activation in R and L sensorimotor cortex, R IFG, and in R and L SMA. At 16 mo. post-TMS (58% named), he also showed significant activation in R and L sensorimotor cortex mouth and R IFG. He now showed a significant increase in activation in the L SMA compared to pre-TMS and at 3 mo. post-TMS (p < .02; p < .05, respectively). At 16 mo. there was also greater activation in L than R SMA (p < .08). At 46 mo. post-TMS (42% named), this new LH pattern of activation continued. He improved on the Boston Naming Test from 11 pictures named pre-TMS, to scores ranging from 14 to 18 pictures, post-TMS (2–43 mo. post-TMS). His longest phrase length (Cookie Theft picture) improved from three words pre-TMS, to 5–6 words post-TMS.Pre-TMS (1.5 years poststroke), P2 had significant activation in R IFG (3% pictures named). At 3 and 6 mo. post-TMS, there was no longer significant activation in R IFG, but significant activation was present in R sensorimotor cortex. On all three fMRI scans, P2 had significant activation in both the L and R SMA. There was no new, lasting perilesional LH activation across sessions for this patient. Over time, there was little or no change in his activation. His naming remained only at 1–2 pictures during all three fMRI scans. His BNT score and longest phrase length remained at one word, post-TMS.Lesion site may play a role in each patient’s fMRI activation pattern and response to TMS treatment. P2, the poor responder, had an atypical frontal lesion in the L motor and premotor cortex that extended high, near brain vertex, with deep white matter lesion near L SMA. P2 also had frontal lesion in the posterior middle frontal gyrus, an area important for naming (Duffau et al., 2003); P1 did not. Additionally, P2 had lesion inferior and posterior to Wernicke’s area, in parts of BA 21 and 37, whereas P1 did not.The fMRI data of our patient who had good response following TMS support the notion that restoration of the LH language network is linked in part, to better recovery of naming and phrase length in nonfluent aphasia. 相似文献

The primary aim of this paper is to analyze the concept of degrees of causal contribution for actual events and examine the
way in which it can be formally defined. This should go some way to filling out a gap in the legal and philosophical literature
on causation. By adopting the conception of a cause as a necessary element of a sufficient set (the so-called NESS test) we
show that the concept of degrees of causation can be given clear and even empirical meaning. We then apply a game theoretical
framework to derive a measure of causal contribution. Our favoured measure turns out to be a generalised version of the normalized
Penrose–Banzhaf index of voting power. 相似文献

Several studies have demonstrated that acquired expertise influences aesthetic judgments. In this paradigm we used functional magnetic resonance imaging (fMRI) to study aesthetic judgments of visually presented architectural stimuli and control-stimuli (faces) for a group of architects and a group of non-architects. This design allowed us to test whether level of expertise modulates neural activity in brain areas associated with either perceptual processing, memory, or reward processing. We show that experts and non-experts recruit bilateral medial orbitofrontal cortex (OFC) and subcallosal cingulate gyrus differentially during aesthetic judgment, even in the absence of behavioural aesthetic rating differences between experts and non-experts. By contrast, activity in nucleus accumbens (NAcc) exhibits a differential response profile compared to OFC and subcallosal cingulate gyrus, suggesting a dissociable role between these regions in the reward processing of expertise. Finally, categorical responses (irrespective of aesthetic ratings) resulted in expertise effects in memory-related areas such as hippocampus and precuneus. These results highlight the fact that expertise not only modulates cognitive processing, but also modulates the response in reward related brain areas. 相似文献

We examined self-objectification in relation to well-being, and the potential moderating versus mediating role of body image coping strategies (appearance fixing, avoidance, positive rational acceptance). Undergraduate women from southern Ontario, Canada (Sample 1, n?=?104; Sample 2, n?=?314) completed measures of depression, disordered eating attitudes, subjective well-being, and body-image coping. Self-objectification was related to greater depression, disordered eating attitudes, and lower subjective well-being. A two-stage mediation model was supported: Body shame and body image coping strategies (appearance fixing and avoidance) partially mediated the associations between self-objectification and outcomes; appearance fixing and avoidance partially mediated the associations between body shame and outcomes. Body image coping strategies did not moderate any of the relations between body shame and outcomes. 相似文献

This review focuses on the “real world” implications of infection with HIV/AIDS from a neuropsychological perspective. Relevant
literature is reviewed which examines the relationships between HIV-associated neuropsychological impairment and employment,
driving, medication adherence, mood, fatigue, and interpersonal functioning. Specifically, the relative contributions of medical,
cognitive, psychosocial, and psychiatric issues on whether someone with HIV/AIDS will be able to return to work, adhere to
a complicated medication regimen, or safely drive a vehicle will be discussed. Methodological issues that arise in the context
of measuring medication adherence or driving capacity are also explored. Finally, the impact of HIV/AIDS on mood state, fatigue,
and interpersonal relationships are addressed, with particular emphasis on how these variables interact with cognition and
independent functioning. The purpose of this review is to integrate neuropsychological findings with their real world correlates
of functional behavior in the HIV/AIDS population. 相似文献

Sex differences in subjective distress to violations of trust in a close relationship were observed among Mexican American
men and women. Imagining a partner’s emotional infidelity and other female-linked violations (for example, a partner who no
longer desires to work) distressed a larger percentage of women than men. In contrast, imagining a partner’s sexual infidelity
and other male-linked violations (for example, a partner who no longer makes an effort to look physically attractive) distressed
a larger percentage of men than women. The results from two studies provided compelling evidence against a social–cognitive
explanation of the sex differences and for an evolutionary psychology explanation based on men and women responding to threats
to their sex-linked mating strategies. 相似文献

This study assessed engaged lifestyle activities (e.g., volunteering, traveling, and public speaking) for centenarians of
the Georgia Centenarian Study. A total of 285 centenarians and near-centenarians (i.e., 98 years and older) and their proxy
informants participated in this study. The Mini-Mental Status Examination (MMSE) was assessed for all centenarians, and proxy
informants reported on lifestyle activities and personality traits of the centenarians. Results suggested that participants
who had volunteered, traveled, and those who had given public talks and balanced their checkbooks were more likely to show
relatively high mental status scores (i.e., MMSE > 17). Personality traits were found to be moderators in the relationship
between engaged lifestyle and mental status: Participants with high levels of Emotional Stability, Extraversion, Openness,
and Conscientiousness and with high levels of engaged lifestyle were more likely to show relatively high mental status scores
(i.e., MMSE > 17), whereas participants with low levels of Emotional Stability, Extraversion, Openness, Agreeableness, and
Conscientiousness and with low levels of engaged lifestyle were more likely to show relatively low mental status scores (i.e.,
MMSE < 18). The results suggest that engaged lifestyle, particularly in combination with personality traits, plays an important
role in the level of cognitive functioning among oldest old adults. 相似文献

This study compared the spatial representation of numbers in three groups of adults: Canadians, who read both English words
and Arabic numbers from left to right; Palestinians, who read Arabic words and Arabic-Indic numbers from right to left; and
Israelis, who read Hebrew words from right to left but Arabic numbers from left to right. Canadians associated small numbers
with left and large numbers with right space (the SNARC effect), Palestinians showed the reverse association, and Israelis
had no reliable spatial association for numbers. These results suggest that reading habits for both words and numbers contribute
to the spatial representation of numbers. 相似文献

Acute stress has been found to have negative and implementation intentions (IIs) to have positive effects on cognitive performance. This study was the first to examine the effects of IIs on executive action control under acute psychosocial stress. Forty-two male subjects aged 21-39 years were randomly assigned to the Trier Social Stress Test (TSST) versus a rest condition. In addition, the instruction to the executive task (a go no-go task) was manipulated (IIs versus standard instruction). After the stress test, a dual-task procedure including a go no-go task was conducted. The TSST resulted in increases in cortisol response, heart rate and state anxiety compared to the rest condition. Acute stress significantly impaired go no-go performance, but only in the group without IIs. We conclude that under acute stress conditions executive functioning is reduced, but the use of IIs can be an effective strategy to overcome this negative effect. 相似文献
