We assessed the behavioral persistence of 65 elementary school children in five situations to explore further the consistency-specificity, or trait-situation, issue. We predicted that the cross-situational consistency of persistence would co-vary with gender, socioeconomic status, and intelligence. The data were analyzed within the context of generalizability theory, and some of our predictions were supported by the results. We contend that the consistency-specificity issue can be profitably studied by direct behavioral assessments within the context of generalizability theory. The implications of the findings for the consistency-specificity issue, and for personality assessment in general, are discussed. 相似文献

The arrow paradox is an argument purported to show that objects do not really move. The two main metaphysics of motion, the At–At theory of motion and velocity primitivism, solve the paradox differently. It is argued that neither solution is completely satisfactory. In particular it is contended that there are no decisive arguments in favor of the claim that velocity as it is constructed in the At–At theory is a truly instantaneous property, which is a crucial assumption to solve the paradox. If so the At–At theory faces the threat that most of our physical theories turn out to be non-Markovian. Finally it is considered whether all those threats and paradoxes are dispelled if only a new metaphysics of persistence is taken into account, namely four-dimensionalism. 相似文献

The aim of the present study was to explore the modifications of scalp EEG power spectra and EEG connectivity during the autobiographical memory test (AM-T) and during the retrieval of an autobiographical event (the high school final examination, Task 2). Seventeen healthy volunteers were enrolled (9 women and 8 men, mean age 23.4 ± 2.8 years, range 19–30). EEG was recorded at baseline and while performing the autobiographical memory (AM) tasks, by means of 19 surface electrodes and a nasopharyngeal electrode. EEG analysis was conducted by means of the standardized LOw Resolution Electric Tomography (sLORETA) software. Power spectra and lagged EEG coherence were compared between EEG acquired during the memory tasks and baseline recording. The frequency bands considered were as follows: delta (0.5–4 Hz); theta (4.5–7.5 Hz); alpha (8–12.5 Hz); beta1 (13–17.5 Hz); beta2 (18–30 Hz); gamma (30.5–60 Hz). During AM-T, we observed a significant delta power increase in left frontal and midline cortices (T = 3.554; p < 0.05) and increased EEG connectivity in delta band in prefrontal, temporal, parietal, and occipital areas, and for gamma bands in the left temporo-parietal regions (T = 4.154; p < 0.05). In Task 2, we measured an increased power in the gamma band located in the left posterior midline areas (T = 3.960; p < 0.05) and a significant increase in delta band connectivity in the prefrontal, temporal, parietal, and occipital areas, and in the gamma band involving right temporo-parietal areas (T = 4.579; p < 0.05). These results indicate that AM retrieval engages in a complex network which is mediated by both low- (delta) and high-frequency (gamma) EEG bands. 相似文献

Although there is a small but growing body of literature on how people make risky decisions for others and predict others' decisions, results seem to be contradictory. The authors contribute to the understanding of these mixed results by investigating how depression affects self–other discrepancies in decision making and the psychological processes that underlie these discrepancies. In an experiment, depressed and nondepressed individuals read a series of scenarios involving decisions about health, money, and interpersonal relationships. They then indicated which of two options they would choose for themselves or for another person, or predicted which option this person would choose for himself or herself. Finally, participants reported benefits and drawbacks of the decisions (i.e., cognitions) and feelings about risk. Depressed individuals were less prone to bias when they predicted others' decisions than nondepressed individuals. Feelings about risk played a key role in determining the direction and the magnitude of this bias. In contrast, both depressed and nondepressed individuals showed bias when they made decisions for others. This bias affected their decisions in opposing ways and was determined by cognitions. This bias is consistent with literature showing that depression is associated with an increased sensitivity to social risks. The authors provide a theoretical explanation of self–other discrepancies in decision making in depressed and nondepressed individuals and conclude that the results support the assumption that depression is associated with psychological processes whose role is to increase sensitivity to social threats rather than with a more general negative bias in cognitive functioning.

Five studies were conducted to develop and validate the Egoistic and Moralistic Self‐enhancement (EMS) scale, a new self‐report measure of egoistic and moralistic self‐enhancement. Exploratory and confirmatory factor analysis provided evidence for a two‐factor structure comprising the tendencies to promote agentic (egoistic) and communal (moralistic) qualities (Study 1). Construct validity was supported by significant correlations with established measures of socially desirable responding, such as the Balanced Inventory of Desirable Responding (Study 2) and the Impression Management scale of the 16 Personality Factors (Study 3). When the EMS scale has been applied in organizational settings, we found that job applicants were more inclined than nonapplicants to promote their own agentic and communal qualities, although differences were more pronounced for egoistic self‐enhancement (Study 4). Findings also suggested that exaggeration of agentic qualities decrease the criterion‐related validity of conscientiousness in predicting job performance (Study 5). Taken together, findings suggest that the EMS scale provides a valid and reliable measure that can be fruitfully used for both theoretical and applied research. 相似文献

It is generally held that noun processing is specifically sub-served by temporal areas, while the neural underpinnings of verb processing are located in the frontal lobe. However, this view is now challenged by a significant body of evidence accumulated over the years. Moreover, the results obtained so far on the neural implementation of noun and verb processing appear to be quite inconsistent. The present review briefly describes and critically re-considers the anatomo-correlative, neuroimaging, MEG, TMS and cortical stimulation studies on nouns and verbs with the aim of assessing the consistency of their results, particularly within techniques. The paper also addresses the question as to whether the inconsistency of the data could be due to the variety of the tasks used. However, it emerged that neither the different investigation techniques used nor the different cognitive tasks employed fully explain the variability of the data. In the final section we thus suggest that the main reason for the emergence of inconsistent data in this field is that the cerebral circuits underlying noun and verb processing are not spatially segregated, at least for the spatial resolution currently used in most neuroimaging studies. 相似文献

REM sleep behaviour disorder (RBD) is a REM sleep-related parasomnia which may be considered a “dissociated state of wakefulness and sleep”, given that conflicting elements of REM sleep (dreaming) and of wakefulness (sustained muscle tone and movements) coexist during the episodes, leading to motor and behavioural manifestations reminiscent of an enacted dream. RBD has been reported in association with α-synucleinopathies: around a third of patients with Parkinson’s disease (PD) have full-blown RBD.Recent data indicate that PD patients with RBD are more prone to hallucinations than PD patients without this parasomnia. However it is still not clear why RBD in PD is associated with an increased prevalence of VHs.Data exist which suggest that visual hallucinations in PD may be the result of untimely intrusions of REM visual imagery into wakefulness. RBD, which is characterised by a REM sleep dissociation pattern, might be a condition that particularly favours such intrusions. However, other hypotheses may be advanced. In fact, deficits in attentional, executive, visuoperceptual and visuospatial abilities have been documented in RBD and found to occur far more frequently in PD with RBD than in PD without RBD. Neuropsychological deficits involving visual perception and attentional processes are thought to play an important role in the pathophysiology of VHs. On this basis, RBD in PD could be viewed as a contributory risk factor for VHs. 相似文献
