Individuals diagnosed with major depressive disorder (MDD) often ruminate about their depression and their life situations, impairing their concentration and performance on daily tasks. We examined whether rumination might be due to a deficit in the ability to expel negative information from short-term memory (STM), and fMRI was used to examine the neural structures involved in this ability. MDD and healthy control (HC) participants were tested using a directed-forgetting procedure in a short-term item recognition task. As predicted, MDD participants had more difficulty than did HCs in expelling negative, but not positive, words from STM. Overall, the neural networks involved in directed forgetting were similar for both groups, but the MDDs exhibited more spatial variability in activation in the left inferior frontal gyrus (a region critical for inhibiting irrelevant information), which may contribute to their relative inability to inhibit negative information. 相似文献

People often behave differently when they know they are being watched. Here, we report the first investigation of whether such social presence effects also influence looking behavior--a popular measure of attention allocation. We demonstrate that wearing an eye tracker, an implied social presence, leads individuals to avoid looking at particular stimuli. These results demonstrate that an implied social presence, here an eye tracker, can alter looking behavior. These data provide a new manipulation of social attention, as well as presenting a methodological challenge to researchers using eye tracking. 相似文献

Research Associate 《Journal of School Psychology》1971,9(4):430-435This research dealt with the reliability and validity of the DTVP when used with a sample of economically disadvantaged, predominantly Negro children from a large eastern city. Regarding reliability, test-retest and split-half procedures were employed; for validity the test was correlated with intelligence and achievement measures. The authors concluded that (a) the total test values alone evidence the necessary reliability to be used with confidence for diagnostic purposes, and (b) the validity of the measure has not been sufficiently demonstrated. 相似文献

Director of Research 《Journal of School Psychology》1971,9(4):445-454The authors of this paper have tried to provide an introduction to the language and problem solving approach called Precision Teaching. Reasons for using a specific language and reporting techniques are listed. Definitions of the terminology and examples taken from the classroom are provided. The main point of this paper is that systematic interventions, precisely described and systematically recorded, lead to the most successful interventions. 相似文献

The study investigated the reliability and validity of the SIT when administered and scored by 33 special education teachers who had no prior psychological testing experience. Subjects were 155 pupils between four and 16 years old who attended 40 Philadelphia schools. Results relative to interscorer differences, internal consistency, stability over time, and concurrent validity upheld the use of this measure as a quick screening device and corroborated Slosson's contention that the test can be administered successfully by teachers. 相似文献

The experiences Black youths bring to school with them constitute a distinctive, viable culture. Their subsequent performance in educational and psychological testing situations cannot be assessed adequately without consideration of their particular attitudes, perceptions, and behavioral patterns, for all of these are determined by a kind of cultural conditioning which differs, in some fundamental ways, from mainstream Americans. Several of the social and psychological characteristics of Black culture are discussed. Included are Blacks' attitudes toward whites, systems of time allocations, expressions of identity, attitudes toward learning, dissemination of information among Blacks, Black learning styles and maturation processes. Each is discussed further in terms of its manifestation in a testing or assessment situation; how it conflicts with the assessor's orientations and expectations; and how distorted, unreliable evaluations result from the failure of assessors to consider implications of cultural relativism in interpreting Black behavior. 相似文献

Being culturally disadvantaged is a social condition which is created, managed, and maintained by both social and professional institutions. When institutions attempt to sustain societal norms by selecting certain attributes and calling them desirable, these institutions are relegating large segments of the population to a deviant status if it does not share these attributes. The “culturally disadvantaged” are such a group. This phenomenon not only results in differential perceptions and expectations, but also influences their self-evaluation, academic success, and career opportunities. The transformation of deviance into incompetency has also led to formally sanctioned methods of managing deviancy. Methods, such as compensatory education, ability grouping, and special class placement can be viewed as maintaining the position that the culturally disadvantaged are indeed deviant and incompetent. 相似文献

In 3 experiments, participants, on signal, moved a cursor from a central position to 1 of 8 numerically labeled locations on the circumference of a clock face. Movements were controlled by a mouse in 1 of 4 conditions: vertical reversal, horizontal reversal, combined reversals, or normal (i.e., no reversals). Participants were trained in 1, 2, or 3 of these conditions and were tested 1 week later with either the same or a different condition. There were improvements across training and perfect retention across the delay. There was little or no transfer, however, even when training involved combined reversals or multiple conditions. These results illustrate severe specificity of training and are interpreted in terms of acquired inhibition of normal responses. 相似文献

The phenomenon of perceptual persistence after the motion stops in shape-from-motion displays (SFM) was used to study the influence of prior knowledge on the maintenance of a percept in awareness. In SFM displays an object composed of discontinuous line segments are embedded in a background of randomly oriented lines. The object only becomes perceptible when the line segments that compose the object and the lines that compose the background move in counterphase. Critically, once the movement of the line segments stops, the percept of the object persists for a short period of time. In the present study, perceptual persistence for digits exceeded that reported for nonsense shapes composed of the same line segments. This result is taken as evidence that the processes involved in the persistence of SFM, and therefore sustained perception, are sensitive to top-down influences. 相似文献
