The purpose of the experiments was to constrain the locus of interference in the attentional blink (AB) paradigm. Two visual stimuli, T1 and T2, were shown 300 msec apart, and each was followed by a mask. T1 was an “H,” an “S,” an “ &, ” or a blank field; T2 consisted of five letters. In Task1, blank fields and & characters could be ignored, whereas Hs and Ss had to be identified and reported. Task2 was always to report as many letters as possible from T2. Task2 performance was lower when T1 had to be reported, as expected from the attentional blink phenomenon (AB). The exposure duration of T2 was also manipulated. More letters could be reported as exposure duration was increased. However, this effect was additive with manipulations of Task1 processing load that produced the AB effect. Log-linear analyses assuming that effects of T2 exposure duration and Task1 load effects occur at functionally distinct stages of processing provided satisfactory fits to the results, suggesting that none of the AB effect occurs as early as those of T2 exposure duration. The results suggest that the locus of the AB effect is later than the stage(s) of processing affected by exposure duration. 相似文献

This paper will focus on the writer’s experience as a native New Yorker relocating to Montgomery, Alabama. The writer will
share how he adjusted and coped with overt discrimination and racism in the context of the high school in which he attended
there-a majority white high school on the “other” side of town. The writer will share how he employed the following coping
mechanisms as methods of adjusting to his new environment: translating emotional experiences into words (relaxation and talk
therapy), involvement with other black positive peers, careful assessment before acting, withdrawal and avoidance, and consuming
African-American literature. 相似文献

There is currently controversy over the validity and applicability of functional behavioral assessment (FBA) procedures with students with emotional/behavioral disorders (E/BD). A set of FBA procedures, including teacher and student interviews and direct classroom observations, were carried out with eight students with disabilities (7 classified E/BD, one classified LD). Results indicated that when all three methods (teacher/student interviews, classroom observations) yielded a ranking for a function they agreed 64% of those occasions. For those situations in which there was overall disagreement there was agreement between teacher interview and classroom observations most of the time. Social validity data indicated that both students and teachers felt that the assessment procedures were a useful and productive process. 相似文献

Evaluating Genetic Counseling: Client Expectations,Psychological Adjustment and Satisfaction with Service 总被引:1,自引:0,他引:1
Periodic evaluations of genetic counseling services are useful for determining the effectiveness of counseling in meetings its psycho-educational aims, as well as identifying where improvements to the service may be made. This study aimed to evaluate the genetic counseling services provided by Genetic Services of Western Australia (GSWA) to determine the impact of counseling on client expectations, satisfaction with the service, and psychological adjustment, defined as wellbeing and perceived personal control (PPC). A total of 122 clients participated in a self-administered survey conducted pre- and post-counseling. Client expectations of the service as a means of providing information were met, and opportunities for counselors to meet client’s expectations of psychological support were identified. Furthermore, counseling was found to maintain and enhance psychological wellbeing of clients. The role of counseling in facilitating the development of PPC was a key contributor to a high sense of satisfaction in clients. 相似文献

In the Implicit Association Test (IAT; Greenwald, McGhee, & Schwartz, 1998) involving race classification (white vs. black),
an apparent compatibility effect is found between the “pleasant” attribute and the “white” category. This race IAT effect
has been interpreted in terms of “implicit prejudice”—that is, more positive evaluation of whites than of blacks that is not
open to consciousness. We suggested instead that the race IAT effect is better interpreted in terms of the salience asymmetry
account proposed by Rothermund and Wentura (2004), whereby greater familiarity with the white category makes it more salient.
Evidence that has been presented against the familiarity interpretation is considered, and alternative interpretations of
findings related to the race IAT effect are discussed. 相似文献

Background: To introduce a person with multiple disabilities to a microswitch-aided program, one has to select a plausible response(s),
that is, a response(s) that can be performed reliably and without excessive effort by the person and can successfully activate
the microswitch(es) available (producing preferred stimuli). This paper provides an overview of the responses adopted for
microswitch activation in research studies during the last 20 years. Method: Computerized and manual searches were carried out to identify the studies published between 1986 and 2005. Forty-eight research
studies were identified. They concerned the use of (1) a single (typical) response, (2) a single (non-typical) response, (3)
multiple (typical and non-typical) responses, and (4) multiple (vocal) responses. Results and discussion: The results showed that 151 of the 190 participants involved in the studies had a positive outcome (i.e., clear increases
in their responding, which suggested that they had learned the association between responding and consequent preferred stimuli).
Failures were largely concentrated in the first group of studies. The discussion focused on (a) the importance of selecting
plausible responses for increasing the chances of success, (b) the need of non-typical responses for persons with minimal
motor behavior, (c) implications of programs with multiple responses on engagement and choice, and (d) relevance of using
vocal utterances. Some suggestions for future research concerning these points were also examined. 相似文献
