The present study is concerned with two Slovenian-speaking patients who were asked to produce, in various tasks, verbs, nouns, and adjectives derived by prefixation with prepositions. Despite differences due to their specific linguistic difficulties, both patients' performance was characterized by the differential processing of prefixes and remaining components of complex words. Prepositions in prefixation were mostly preserved, and less frequently substituted, regardless of the numerous errors produced in the remaining portion of the words. These errors seem clearly determined by the morphological structure of the words and therefore appear to be authentic morphological errors. These findings contribute to the theoretical debate on mental lexical representation, speaking in favor of a morphological decomposition in processing of prefixed complex words at different processing levels. 相似文献

Three experiments were conducted examining unimodal and crossmodal effects of attention to motion. Horizontally moving sounds
and dot patterns were presented and participants’ task was to discriminate their motion speed or whether they were presented
with a brief gap. In Experiments 1 and 2, stimuli of one modality and of one direction were presented with a higher probability
( p = .7) than other stimuli. Sounds and dot patterns moving in the expected direction were discriminated faster than stimuli
moving in the unexpected direction. In Experiment 3, participants had to respond only to stimuli moving in one direction within
the primary modality, but to all stimuli regardless of their direction within the rarer secondary modality. Stimuli of the
secondary modality moving in the attended direction were discriminated faster than were oppositely moving stimuli. Results
suggest that attending to the direction of motion affects perception within vision and audition, but also across modalities. 相似文献

The resource view on vigilance performance was tested. First, a low demanding task was compared with a similar low demanding task in which stimulus presentation was less monotonous due to added, irrelevant, stimuli. The resource view, maintaining that vigilance is lowered by hard mental work, predicts that addition of irrelevant stimuli will not affect performance. The classic arousal theory, however, states that arousal drops due to monotonous stimulus presentation and predicts that decreasing monotony will enhance performance. Results showed that performance was unaffected by added stimuli. Second, we tested whether a high-demanding task (with identical stimulus presentation as the low demanding task, but different instruction) would cause a greater decline in performance than the low demanding task. Indeed, in the high-demanding task performance was affected most. In sum, it appears that vigilance decreases due to hard mental work, which requires many resources. Both overall performance and decrement in performance can be explained in terms of resources, and this suggests that vigilance tasks should be resource-demanding tasks, which do not have to be of long duration. 相似文献

The psychometric properties of the original version of the Sensation Seeking Scale (Form V) were analyzed in a sample of 1,006 Spanish university students. The total sample was randomly split into two halves. Exploratory factor analyses were conducted on the calibration sample (n=504), whereas confirmatory factor analysis procedures were performed on the validation sample (n=502). As previous studies have suggested, exploratory factor structure indicated that several items load on a different factor or have loadings lower than .30. Those problems were surpassed when the best five items per factor were factor analyzed again. The confirmatory factor analyses showed that a 4-factor simple structure model gave a clearly imperfect fit. A model of 20 items (5 items per factor) gave a better fit, although with similar problems regarding the low reliabilities of the Experience Seeking and Boredom Susceptibility subscales. The need for improvement of the four-factor structure is discussed. 相似文献

In this study the relevance of the concept of mental kinesiophobia (respectively cogniphobia or fear of mental exertion) for clients with chronic stress problems was explored. It was hypothesized that cognitive, chronic stress complaints, such as concentration problems or decreased problem solving abilities, could be catastrophized as signs of heightened personal vulnerability, with a chance of becoming permanent. As a consequence, mental exertion is avoided. This line of reasoning comes from the existing concept of kinesiophobia. This concept describes the avoidance behavior in chronic benign pain patients and refers to their fear of inflicting irreversible bodily damage due to physical exertion.An illustrative case of cogniphobia is presented. In an explorative pilot-study it was demonstrated that chronically stressed clients scored significantly higher on an experimental questionnaire measuring avoidance tendencies for mental exertion, compared with actively working employees. Consequences for treatment and suggestions for further study are discussed. 相似文献

Psychopathy and antisocial personality disorder (APD) have long been considered important risk factors for criminal behavior and incarceration. However, little is known about the psychobiological underpinnings that give rise to the disinhibited behavior of female offenders. Using an instructed fear-conditioning paradigm and a sample of incarcerated female offenders, we manipulated attentional focus and cognitive load to characterize and differentiate between the dysfunctional cognitive and affective processes associated with these syndromes. We used fear-potentiated startle (FPS) and event-related potentials as measures of affective and cognitive processing, respectively. After controlling for APD symptoms, psychopathic women displayed greater FPS while attending directly to threat-relevant stimuli and displayed less FPS while performing a demanding task that directed attention to threat-irrelevant information. Conversely, controlling for psychopathy, women with high APD symptoms displayed less overall FPS, especially when instructed to focus on threat-relevant stimuli. However, as the demands on cognitive resources increased, they displayed greater FPS. For both psychopathy and APD, analysis of the event-related potentials qualified these findings and further specified the abnormal cognitive processes associated with these two syndromes. Overall, simultaneous analysis of psychopathy and APD revealed distinct patterns of cognitive processing and fear reactivity. 相似文献

This paper critically discusses D. Z. Phillips’ use of literary works as a resource for philosophical reflection on religion.
Beginning by noting Phillips’ suggestion, made in relation to Waiting for Godot, that the possibilities of meaning that we see in a literary work can reveal something of our own religious sensibility,
I then proceed to show what we learn about Phillips from his readings of certain works by Larkin, Tennyson, and Wharton. Through
exploring alternative possible readings, I argue that, although Phillips’ discussions are of considerable philosophical interest,
they undermine his claim to be deploying a purely contemplative hermeneutical method. 相似文献
