Humility training is conceptualized as an appropriate treatment for persons who occasionally describe themselves, but are most frequently described by others as overbearing, insensitive and deceitful. Procedures are outlined to identify unrecognized fears and improve interpersonal skills. Humility is presented as a counterpoint to assertiveness and aggression/anger control interventions.  相似文献

A blind woman who is mentally retarded was employed (as peer care-giver) to promote and eventually share the occupational engagement of a deaf-blind adolescent (trainee) who was dependent on physical prompting. A computer-aided program was used to provide objects for the responses and facilitate orientation and mobility. The trainee was also exposed to the computer-aided program individually to assess the effects of the program per se. The results showed highly positive changes only in the condition involving the peer care-giver. In this condition, the trainee performed high frequencies of correct responses. Moreover, the care-giver managed to share responding with the trainee. Technical and practical aspects of the findings are discussed.  相似文献

Random dots moving with various velocity gradients were presented to observers; the motion was yoked to head movement in one condition and to no head movement in another. In Experiment 1, 12 observers were shown motion gradients with sine, triangle, sawtooth, and square waveforms with amplitudes (equivalent disparities) of 12′ and 1° 53′. In Experiment 2, 48 observers were shown only the sinewave or square-wave gradient of 1° 53′ disparity either with or without head movement so that the observers’ expectation to see depth in one condition did not transfer to another. The main findings were: (1) with 12′ disparity, the head-movement condition produced perceived depth but almost no perceived motion, whereas the no-head-movement condition produced both perceived depth and perceived motion; (2) with 1° 53′ disparity, both conditions produced perceived depth and perceived motion; and (3) when the expectation to see depth was removed, the no-head-movement condition with the square-wave gradient produced no perceived depth, only motion. We suggest that monocular stereopsis with head movement can be achieved without perception of motion but monocular stereopsis without head movement requires perception of motion.  相似文献

Responses to recently ignored information may be slower or less accurate than responses to information not recently encountered. Such negative priming effects imply that the mechanism of selective attention operates on unattended, as well as attended, information. In the present experiment, subjects judged the second and fourth letters of five-letter strings (e.g., BABAB) as “same” or “different.” Responses were slower when a target letter was identical to the distractors presented in the immediately preceding trial. This effect did not depend on which response was required on the current or preceding trial. The results suggest that ignored information is functionally disconnected from the response system as a whole, rather than from a specific response.  相似文献
