Thirty-six university students were tested in a plausibility judgment task using a self-paced listening paradigm under no-interference and two-digit load conditions. Listening times were longer at syntactically more complex portions of syntactically more complex sentences, and greater loads led to increased listening times. However, listening times at syntactically more complex positions in syntactically more complex sentences did not increase more than listening times at comparable positions in syntactically simple sentences under digit load conditions. The results indicate that a concurrent memory load does not reduce the availability of working memory resources used for on-line syntactic processing and, thus, provide evidence that the working memory system used for assigning syntactic structure is separate from that measured by standard working memory tasks.  相似文献

The psychometric properties of several commonly used verbal working memory measures were assessed. One hundred thirty-nine individuals in five age groups (18–30, 50–59, 60–69, 70–79, and 80+ years) were tested twice (Time I and Time II) on seven working memory span measures (alphabet span, backward digit span, missing digit span, subtract 2 span, running item span, and sentence span for syntactically simple and complex sentences), with an interval of approximately 6 weeks between testing. There were significant effects of age on all but two of the tasks. All the measures had adequate internal consistency. Correlations between performances at Time I and Time II were significant for all the tasks, other than the missing digit span task. The magnitude of the correlations was similar across the age groups and ranged from .52 to .81. Classification of subjects into discrete memory span groups on the basis of a single measure was highly inconsistent across testing sessions and tasks. Classification into upper and lower quartiles was more stable than using a cutoff score for group membership or than classification into high-, medium-, and low-span groups. Correlational analyses showed that there was a moderate relationship between performances on many of the span tasks. Confirmatory factor analysis suggested that six of the seven tasks reflected a common factor. Both test—retest reliability and stability of classification improved when a composite measure reflecting performance on several tasks was used.  相似文献

The fundamental assumption behind Leslie’s theory of mind mechanism theory is that from 18 months onwards a single device, the theory of mind mechanism, allows children to represent both pretend and belief in terms of propositional attitudes. This is compared with Perner’s argument that early pretence is not understood in terms of propositional attitudes. Recent modifications to Leslie’s theory aim to explain why children younger than 4 years fail the false belief test. Leslie argues that the correct proposition is computed, not by the theory of mind mechanism, but by the selection processor, a later-developing executive device. In this paper I examine the coherence of Leslie’s revised theory and conclude that representing beliefs is now entirely the task of the selection processor; the theory of mind mechanism is no longer involved, thus contravening the fundamental assumption of the theory. The conclusion is that the theory and the assumption should be abandoned.  相似文献

We examined whether eight capuchins and eight chimpanzees were able to retrieve a reward placed inside a tube, of varying length, by selecting the correct stick from different sets of three sticks differing in length (functional feature) and handle (non-functional feature). Moreover, to investigate whether seeing the stick inside the tube (visual feedback) improves performance, half of the subjects were tested with a transparent apparatus and the other half with an opaque apparatus. Phase 1 included (a) Training 1 in which each stick had a different handle and (b) Transfer 1 in which the handles were switched among sticks, so that the functional tool had the same length but a different handle than before. The seven chimpanzees and one capuchin that passed Transfer 1 received Transfer 2. The other subjects received (a) Training 2, which used the same sticks from Phase 1 with handles switched in every trial, and (b) Transfer 2 in which the tube was longer, all sticks had the same new handle, and the formerly longest tool became intermediate in length. Eight chimpanzees and three capuchins passed Transfer 2. Results showed that (1) chimpanzees applied relational structures in tool using tasks more quickly than capuchins and (2) capuchins required more varied experience to attend to the functional feature of the tool. Interestingly, visual feedback did not improve performance in either species.  相似文献

This article defines ways in which a community can honor older adults as an invaluable resource to community life. A biographical study of a particular community is undertaken in order to extricate its theological convictions and ethical values. This study underscores the pivotal role of older adults in community function. Moreover, this article challenges scholars, caregivers, congregations to develop theories and strategies of care efficacious for healing.  相似文献

Psychopathy is often used to settle disputes about the nature of moral judgment. The “trolley problem” is a familiar scenario in which psychopathy is used as a test case. Where a convergence in response to the trolley problem is registered between psychopathic subjects and non-psychopathic (normal) subjects, it is assumed that this convergence indicates that the capacity for making moral judgments is unimpaired in psychopathy. This, in turn, is taken to have implications for the dispute between motivation internalists and motivation externalists, for instance. In what follows, we want to do two things: firstly, we set out to question the assumption that convergence is informative of the capacity for moral judgment in psychopathy. Next, we consider a distinct feature of psychopathy which we think provides strong grounds for holding that the capacity for moral judgment is seriously impaired in psychopathic subjects. The feature in question is the psychopathic subject’s inability to make sincere apologies. Our central claim will be this: convergence in response to trolley problems does not tell us very much about the psychopathic subject’s capacity to make moral judgments, but his inability to make sincere apologies does provide us with strong grounds for holding that this capacity is seriously impaired in psychopathy.  相似文献

African American women at increased risk of HIV/sexually transmitted infection (STI) may engage in risky sex as a coping mechanism for depressed economic conditions. This study examines the association between high-risk sexual behavior and structural determinants of sexual health among a sample of young African American women. 237 young African American women (16–19 years old) from economically disadvantaged neighborhoods in North Carolina were enrolled into a randomized trial testing the efficacy of an adapted HIV/STI prevention intervention. Logistic regression analyses predicted the likelihood that young women reporting lack of food at home, homelessness and low future prospects would also report sexual risk behaviors. Young women reporting a lack of food at home (22 %), homelessness (27 %), and low perceived education/employment prospects (19 %) had between 2.2 and 4.7 times the odds as those not reporting these risk factors of reporting multiple sex partners, risky sex partners including older men and partners involved in gangs, substance use prior to sex, and exchange sex. Self-reported structural determinants of sexual health were associated with myriad sexual risk behaviors. Diminished economic conditions among these young women may lead to sexual risk due to hopelessness, the need for survival or other factors.  相似文献

This study aimed at the assessment of psychometric properties of the Italian version of the Spanish Burnout Inventory (SBI-Ita) in a sample of Italian teachers and the analysis of burnout profiles based on a model that includes four dimensions: Enthusiasm toward job, Psychological exhaustion, Indolence, and Guilt. A self-reported questionnaire was filled out by 689 Italian teachers. Data analyses performed Multi-sample Confirmatory Factor Analysis and Hierarchical Cluster Analysis. Results confirmed the hypothesized four-factor structure and the discriminant role of Guilt in differentiating clusters. Results highlights the reliability of the SBI-Ita in the assessment of teachers’ burnout. Furthermore, results evidence for a new typology of burnout that differentiate guilty from non-guilty professionals.  相似文献
