Four experiments designed to investigate a visual search task are reported. In each experiment, subjects searched for either a two-dimensional shape rotated in depth among frontal-parallel distractors or a frontal-parallel shape among distractors that were rotated in depth. The principal independent variable was search-set size. In addition, over the four experiments, a variety of spatial arrangements and two axes of rotation in depth were sampled. The chief aim of the experiments was to adduce evidence bearing on the attentional demands of searching for depth. The slopes of the reaction-time (RT) functions were taken as diagnostic. Experiments 1–3 exhibited positive slopes for the RT-set-size function. These slopes appear to be due to a conscious adoption of a serial search strategy by the subjects. When this tendency was suppressed by the procedures of Experiment 4, the slope of the RT-set-size functions did not differ significantly from zero. We conclude that, in agreement with the findings of other studies, slant-in-depth can be detected preattentively. 相似文献

Self-Discrepancies as Predictors of Vulnerability to Distinct Syndromes of Chronic Emotional Distress 总被引:1,自引:0,他引:1
Two types of self-discrepancy differing in both domain and standpoint of self-guide were examined as predictors of vulnerability to chronic emotional syndromes. Study 1 assessed discrepancy between the actual/own self-state and the ideal/own self-guide and between the actual/own self-state and the ought/other self-guide in predicting syndromes of dejection and agitation as well as different types of anger. Actual/own: ideal/own discrepancy (AI) was uniquely related to dejection, frustration, and anger at self as measured 2 months later; actual/own:ought/other discrepancy (AOO) was uniquely related to agitation and to anger at others and resentment. Study 2 used structural equation modeling of the relations between AI and AOO discrepancy and social anxiety versus depression as measured weeks later. A model in which AOO was more strongly associated with social anxiety and AI was more strongly associated with depressive symptoms provided the best fit. The results support the convergent and discriminant validity of a self-discrepancy model of vulnerability to chronic emotional syndromes. 相似文献

Three patients with severe aphasia and right hemiplegia are described who could write to dictation with the right arm using a limb prosthesis though agraphic with the "intact" left hand. The phenomenon of "hemiplegic writing" is explained as an access to submerged or preprocessing levels in language and action structure, through the use of older proximal motor systems. This interpretation has implications for our understanding of language and brain function, as well as for approaches to the treatment of patients with severe language disorders. 相似文献

This study examined the structure, concurrent validity, and reliability of a hassle measure for middle-aged adults in both event frequency and intensity recordings. The measure included a range of interpersonal day-to-day events and re-examined aspects of the primary appraisal confounding debate between Lazarus and colleagues (Lazarus, Delongis, Folkman, & Gruen, 1985) and Dohrenwend and Shrout (1985). Of the 373 participants, 73% were female, 72% were in paid work, 69% were in permanent relationships and 62% had children. Principal component analyses of separate hassle frequency and intensity scores highlighted components consistent with previous research. There were seven interpersonal and four non-interpersonal subscales associated with negative events with family and friends, work, health, money, and household. The subscales had very good reliability and concurrent validity and there were generally strong correlations (i.e. up .84) between frequency and intensity scores for each subscale. Given some important sampling limitations (e.g. female overrepresentation) the findings show a psychometrically sound hassle scale for adults. 相似文献

Impulse-control disorders have received relatively little attention from the mental health community. An increasing awareness of the prevalence and impact of these disorders is emerging. Among impulse-control disorders, problematic Internet use has been considered and examined. Prevalence estimate studies indicate that problematic Internet use is experienced across geographic locations by many individuals of diverse backgrounds. This review examines problematic Internet use from epidemiological and clinical perspectives. Clinicians should be familiar with the extent of problematic Internet use and the data regarding the efficacies and tolerabilities of available treatments. 相似文献

The authors offer an integral approach to counseling ethics using K. Wilber's (2000a, 2000b) integral metatheory. The article examines traditional counseling ethics through the lens of K. Wilber's (2000a, 2000b) “all‐quadrants, all‐levels” model, consisting of quadrants, levels, lines, states, and types. The authors begin with the 4 quadrants and how they can inform understanding of traditional counseling ethics. Vertical development in relation to counseling ethics is addressed, followed by a case study of an ethical dilemma in counseling. The authors offer an integrally informed process of ethical decision making that can be seen to complement less comprehensive ethical decision‐making models. 相似文献

Abstract : When it comes to how Heidegger understands theology, Martin Luther was instrumental in his early formulations. Heidegger's interpretation of Luther leads him to descry theology as a discipline best left unfettered by metaphysics and this attitude is carried right through Heidegger's career. By explicating Luther's influence upon Heidegger's early Freiburg lectures from 1919‐1923, we can raise important questions about the nuanced way Heidegger construes Luther's theology in the hopes of inspiring key insights for Luther's appropriation in current post‐Heideggerian theology. 相似文献

The purpose of this study was to address the attentional cost of sensorimotor coordination by determining if changes to the mechanical context of movement would influence the ability to attend and respond to an alternate stimulus. Nine right-handed participants performed rhythmic pronation and supination movements of the forearm in time with an auditory metronome. A secondary task, consisting of a pedal response to visual probe stimuli, was employed to infer the attentional cost of the coordination task. When the axis-of-rotation (AOR) was placed below the long axis of the forearm, the average time to react (RT) to the probe stimuli was greater for the supinate-on-the-beat condition than for the pronate-on-the-beat condition. Conversely, with the AOR above the forearm, RT for the pronate-on-the-beat pattern was greater than that for the supinate-on-the-beat pattern. Thus, changing the mechanical context of an upper limb coordination task altered the central processing cost required to maintain pattern stability. This finding provides further evidence that the attentional resources required to produce a particular movement are determined by the ease with which the action is executed by the sensorimotor system. 相似文献

It is important to understand how cultural values, beliefs and traditions of foster parents are related to placement success because a substantial proportion of children in care come from culturally diverse backgrounds. In the present study participants were asked about resources they saw as necessary to improve their confidence fostering children from culturally diverse backgrounds. Sixty-one foster parents from a central Canadian province participated in a telephone interview that included the question: “what would help you feel more confident about fostering children with different values, beliefs and traditions?” A total of 35 unique responses were obtained and grouped together by 13 foster parents. Multidimensional scaling and cluster analysis were used to analyze the grouping data. Foster parents described six themes: understanding different cultures, training, self awareness, agency support, open discussion and community services. There were several similarities and differences between the perspectives of foster parents interviewed and the literature. Implications for future research are discussed. 相似文献
