By reversing the presentation order and frequency of stimuli between two series of trials, we studied how the category scale for visual speed is transferred across stimulus contexts. Participants judged five stimulus speeds, using three categories (slow, moderate, and fast). In Experiment 1, mainly frequent speeds (either low or high) occurred on the initial trials. This manipulation produced divergent preshift ratings for identical stimuli. Although subsequent reversal of stimulus context resulted in a reversal of scales, the adjustment was incomplete: The postshift ratings did not match the comparable preshift ones. In Experiment 2, mainly infrequent speeds were presented initially. Now the preshift ratings coincided, but higher postshift ratings occurred with the frequent high-speed rather than with the frequent low-speed stimuli. We conclude that with transfer into a new context, the spontaneous adjustment of response scale is determined (1) by the preshift primacy and the postshift frequency effects and (2) by the preshift frequency effect extended to the postshift trials.  相似文献

Tense and syntactic processes in agrammatic speech   总被引:3,自引:0,他引:3  
This study focuses on inflectional errors in a group of eight, English-speaking people with agrammatism. Subjects were required to provide inflected verbs in declarative sentences and construct negative sentences. The errors made by these speakers are considered in terms of whether they resemble the errors made by children at the Optional Infinitive Stage. Results confirm that the errors differ from those made by children and that a different explanation is required. Explanations offered by Borer and Rohrbacher (1997) and by Friedmann and Grodzinsky (2000) are discussed but are considered inadequate to deal with our data. It is proposed that agrammatic speakers have problems with the implementation of grammar and particularly with syntactic processes such as feature-checking.  相似文献

In order to explore the effects of German unification on the life course of East German women of three age cohorts, 36 biographical interviews were conducted. The purpose of the research was to examine whether unification meant a complete break with the German Democratic Republic's (GDR) standard biography in terms of a voluntary acceptance of West German patterns, or a modification of old patterns based on necessity. Results demonstrate that the historical moment of 1989/90 (the Wende or turning point) has changed the life plans of the three cohorts of women in East Germany in different ways, depending on its timing in their life course. The life patterns of the youngest cohort differ most significantly from the standard biography of the GDR woman in that family formation is postponed and employment prioritized over family. Rather than being a complete break with tradition and a voluntary adoption of Western norms, this means a modification of the life course, because the desire to combine work and family continues to dominate.  相似文献

The experiment was carried out to determine whether exposure to an uncontrollable relationship between an action and its outcome during a non-aversive pretreatment phase would affect subsequent ratings of perceived control emitted by human participants. Its other aim was to investigate the effect of such pre-exposure on the attentional focus of humans on internal and external cues. Participants were assigned to one of three groups; an uncontrollable pretreatment, a controllable pretreatment, and no pretreatment. Participants exposed to uncontrollable outcomes (unsolvable problems) gave lower ratings of control over a produced outcome than the other two groups, indicating the interference with subsequent judgments of control. The exposure to uncontrollable outcomes also increased levels of distraction produced by an external cue in a reaction time experiment. Such an effect was not found in the groups who had not been exposed to uncontrollable outcomes. These dual effects are similar to those noted in non-humans subjected to uncontrollable outcomes.  相似文献

OBJECTIVE: To investigate the attitudes of terminally ill individuals toward the legalization of euthanasia or physician-assisted suicide (PAS) and to identify those who would personally desire such a death. DESIGN: In the Canadian National Palliative Care Survey, semistructured interviews were administered to 379 patients who were receiving palliative care for cancer. Patients who expressed a desire for physician-hastened death were followed prospectively. MAIN OUTCOME MEASURES: Attitudes toward the legalization of euthanasia or PAS were determined, as was the personal interest in receiving a hastened death. Demographic and clinical characteristics were also recorded, including a 22-item structured interview of symptoms and concerns. RESULTS: There were 238 participants (62.8%) who believed that euthanasia and/or PAS should be legalized, and 151 (39.8%) who would consider making a future request for a physician-hastened death. However, only 22 (5.8%) reported that, if legally permissible, they would initiate such a request right away, in their current situations. This desire for hastened death was associated with lower religiosity (p=.010), reduced functional status (p=.024), a diagnosis of major depression (p<.001), and greater distress on 12 of 22 individual symptoms and concerns (p<.025). In follow-up interviews with 17 participants, 2 (11.8%) showed instability in their expressed desire. CONCLUSION: Among patients receiving palliative care for cancer, the desire to receive euthanasia or PAS is associated with religious beliefs; functional status; and physical, social, and psychological symptoms and concerns. Although this desire is sometimes transitory, once firmly established, it can be enduring.  相似文献

Using both a lab experiment and actual transaction data, we investigated whether and how incidental similarities (e.g., shared letters between buyer and seller's name) might influence buyer behavior. Particularly, while prior work suggests that consumers generally prefer incidental similarity, we use the context of Internet auctions to show that this preference reverses when prices are high. Under these conditions, buyers avoid incidentally similar sellers. We speculate that this effect is tied to individuals' motive to self‐protect. Implications for theory and practice are discussed.  相似文献

Events (e.g., “running” or “eating”) constitute a basic type within human cognition and human language. We asked whether thinking about events, as compared to other conceptual categories, depends on partially independent neural circuits. Indirect evidence for this hypothesis comes from previous studies showing elevated posterior temporal responses to verbs, which typically label events. Neural responses to verbs could, however, be driven either by their grammatical or by their semantic properties. In the present experiment, we separated the effects of grammatical class (verb vs. noun) and semantic category (event vs. object) by measuring neural responses to event nouns (e.g., “the hurricane”). Participants rated the semantic relatedness of event nouns, as well as of two categories of object nouns—animals (e.g., “the alligator”) and plants (e.g., “the acorn”)—and three categories of verbs—manner of motion (e.g., “to roll”), emission (e.g., “to sparkle”), and perception (e.g., “to gaze”). As has previously been observed, we found larger responses to verbs than to object nouns in the left posterior middle (LMTG) and superior (LSTG) temporal gyri. Crucially, we also found that the LMTG responds more to event than to object nouns. These data suggest that part of the posterior lateral temporal response to verbs is driven by their semantic properties. By contrast, a more superior region, at the junction of the temporal and parietal cortices, responded more to verbs than to all nouns, irrespective of their semantic category. We concluded that the neural mechanisms engaged when thinking about event and object categories are partially dissociable.  相似文献

The ChiP-C is a clinically oriented questionnaire for assessing the quality of the child-parent relationship according to the child’s subjective appraisal. The ChiP-C is based on family systems theory and a cumulative vulnerability model. The questionnaire consists of 36 items representing three resource scales, five risk scales, and one additional scale. This article presents the theoretical framework and main psychometric properties of the ChiP-C. A school-based sample of 1,377 youth (ages 10–20; M = 14.4) and a clinic-referred consecutive sample of 197 patients (ages 10–18, M = 14.0) were surveyed. Construct validity was determined by confirmatory factor analyses. The mean of the internal consistencies was 0.79. Systematic correlations between the ChiP-C scales and the German EMBU confirmed the convergent and discriminant validity of the ChiP-C. Moreover, all ChiP-C scales were shown to be significantly correlated with psychopathological symptoms as measured by parent and youth questionnaires. The ChiP-C can be considered an economical screening instrument for a reliable and valid assessment of strengths and disturbances of the child-parent relationship according to the child’s subjective appraisal.  相似文献
