不同年龄儿童对权威认知水平的研究

文章采用两难故事法对儿童(7～17岁)在与权威(父母、教师与社会上的成人)发生矛盾冲突时所处的认知水平进行了研究,结果发现儿童对有关权威的规则与命令并不是一种盲目的服从与不服从,而是依据自己对权威的一种认知而行动的,儿童对权威的认知处于一种发展过程中,不同年龄儿童对权威的认知水平不同且存在显著的年龄差异和对象差异。     

Thresholds for the perception of angular acceleration as indicated by the oculogyral illusion

A motorized chair (with precise servo controls) accelerated the observer in a clockwise (CW) or counterclockwise (CCW) direction at rates that ranged in logarithmic progression from 0.02 to 6.00 deg/sec². The target, a narrow collimated Line of light, was contained within a goggle device worn by the observer and therefore fixed in relative position to him. The illusion, appearing as rightward or leftward movement of the visual target in the direction of acceleration, was determined by a double staircase procedure among 300 normal and 4 labyrinthine-defective observers. None of the latter perceived the illusion. The majority of normal observers revealed no substantial directional difference (CW vs. CCW threshold). Threshold frequency distributions ranged in rate (deg/sec²) from 0.020 to 0.950; the threshold of response in more than half the normal observers was less than 0.10, in over three-fourths was less than 0.20, in over 90% less than 0.30, and 100% less than 1.00.     

Design considerations for an on-line computer system for automated psychiatric assessment

The computer-assisted multidisciplinary Psychiatric Assessment Unit at the Salt Lake City VA Hospital required a unique computer system. Design considerations and procedures for development of a Psychiatric Real-Time Information System for Management (PRISM) are outlined. This design is presented as an example for others considering implementing on-line systems. Advantages of the approach are discussed.
