罗夏墨迹测验的客观性探索——一项来自于眼动实验的研究

本文对罗夏墨迹测验施测过程中正常被试做出第一反应之前的眼动特征进行了分析研究,结果表明:十张图片的第一反应时、注视点个数、平均注视时间存在显著性差异,其中彩色图片的第一反应时较长、注视点个数较多、注视时间长,被试更多关注图片上半部分.初步验证了罗夏墨迹测验具有一定的客观性.     

Chinese deaf adolescents' free recall of taxonomic, slot-filler, and thematic categories

Four experiments were conducted to show that deaf adolescents tended to process information in different ways from hearing adolescents. Memorizing items sequentially shown on computer screens under the control of their articulators' movements, deaf adolescents tended to treat items that cohered as taxonomic, thematic, or slot-filler categories as isolated pieces of information. Having to perceive information by means of sign language, however, their achievements were not worse than those of hearing adolescents anymore, no matter whether the stimuli were presented as words or pictures. They could not only utilize categories relations to help memorize categories exemplars but were relatively better aware of slot-filler or thematic than taxonomic relations as well, suggesting that they had a relatively delayed development of taxonomic category representations in comparison with hearing adolescents.     

自主阅读和伴读方式下3～4岁幼儿图画书阅读的眼动研究

研究以SMI眼动仪为工具考察了30名3～4岁幼儿在自主阅读和伴读方式下阅读图画书的特点。结果发现:(1)阅读方式对幼儿的眼动模式产生一定影响:伴读方式下儿童的平均注视时间更短,伴读方式有利于3～4岁幼儿对图画书的信息加工。(2)幼儿对图画书中关键信息的注视受到阅读方式的影响,表现为伴读方式下幼儿能更早注视关键信息。(3)幼儿在两种阅读方式下均表现为图画优先、人物主体优先和面部优先的特点而很少关注文字。     

单字词和复合词预视加工的差异性研究：词边界信息无影响

本实验采用眼动轨迹记录法并结合边界范式（Rayner, 1975）,操纵单字词和双字复合词的首字为一致预视或假字预视,考察单字词和复合词预视加工的差异性。另外,通过在中文句子中加入词边界信息——词间阴影,以考察词间阴影对单字词和复合词预视加工的影响。实验结果表明,复合词的预视效应大于单字词,并且词间阴影对单字词和复合词的预视加工均没有显著影响。因此,与印欧语系相比,中文阅读中更大更强的预视效应需从更深层次的语言和认知因素进行探讨。该结果更倾向于支持词切分和词汇识别模型。     

Dissecting the conditioned pecking response: an integrated system for the analysis of pecking response parameters.

The conventional pecking response key, although an excellent transducer of response rate, can provide minimal information on the topography, coordination, or localization of conditioned pecking. We describe the hardware and software components of a system that, in addition to recording response rates, permits simultaneous "on-line" monitoring of head acceleration, jaw movement, terminal peck location, and duration of pecking response. Head movements are monitored with a miniature accelerometer, jaw movements with a magnetosensitive transducer, and peck location with modified touch screen technology. Initial experiments with the system suggest that it will be useful in studies of response differentiation, acquisition and maintenance of complex discriminations, and interaction of conditioned and unconditioned stimuli in the control of pecking response probability and response topography.     

Where Have All the Children Gone? Movement from Child to Adult Mental Health Systems

The mental health histories of the 448 children 15 and 16 years of age who were admitted to state-operated children's psychiatric inpatient services in New York during 1982 were reviewed for the 11 year period through April 1993, Thirty-three percent were served as adults (after age 18) in the state-operated adult civil mental health system; 42% of these individuals were still receiving services at the end of the period. 113 of the 146 individuals served as adults were served only in the civil system. Thirteen percent of the cohort received some of their mental health services as adults in the state-operated adult forensic mental health system due to criminal law involvement. This includes nine percent who received mental health services while they were inmates in state prisons. Twenty four of the 57 forensic clients received services as adults only in the forensic system. Diagnostic, demographic, and service history characteristics of the groups were compared to foster an early understanding of policy and programmatic issues related to movement from the child mental health system to the adult system. Baseline (1982) information was used to identify predictors of later service utilization.     

Sign- versus goal-tracking: effects of conditioned-stimulus-to-unconditioned-stimulus distance.

Three pigeons were exposed sequentially across experimental phases to five different distances between the conditioned stimulus and the site of the unconditioned stimulus in a sign-/goal-tracking procedure. A computer-controlled tracking system provided a continuous record of the bird's position by continuously monitoring the location of the bird's head in three-dimensional space. It was found that birds sign-tracked (i.e., approached the conditioned stimulus) when the conditioned stimulus was closest to the site of the unconditioned stimulus, goal-tracked (i.e., approached the site of the unconditioned stimulus in the presence of the conditioned stimulus) when the conditioned stimulus was farthest from the site of the unconditioned stimulus, and engaged in both sign- and goal-tracking (or something intermediate) at intermediate conditioned-stimulus-to-unconditioned-stimulus distances. When both sign- and goal-tracking occurred, the former tended to occur in the first half and the latter in the second half of the interval in which the conditioned stimulus was present. The results suggest (a) whether sign- or goal-tracking (or both) occurs is a function of the distance of the conditioned stimulus from the site of the unconditioned stimulus, (b) the fact that pigeons but not rats have been found to sign-track consistently throughout the duration of the conditioned stimulus may be due to quantitatively rather than qualitatively different effects of conditioned-stimulus-to-unconditioned-stimulus distance across species (i.e., a "short" conditioned-stimulus-to-unconditioned-stimulus distance for a pigeon may be a "long" one for a rat), and (c) sign- and goal-tracking may be competing behavioral tendencies that can (e.g., at intermediate conditioned-stimulus-to-unconditioned-stimulus distances) cancel each other out. The findings lend support to theories that specify an interaction between phylogenetic and reinforcement variables in determining whether sign- or goal-tracking will occur in any given experimental preparation.     

Assisted Suicide,Suffering and the Meaning of a Life

The ethical problems surrounding voluntary assisted suicide remain formidable, and are unlikely to be resolved in pluralist societies. An examination of historical attitudes to suicide suggests that modernity has inherited a formidable complex of religious and moral attitudes to suicide, whether assisted or not. Advocates usually invoke the ending of intolerable suffering as one justification for euthanasia of this kind. This does not provide an adequate justification by itself, because there are (at least theoretically) methods which would relieve suffering without causing the physical death of the suffering person. Carried to extremes, these methods would finish the life worth living, but leave a being which was technically alive. Such acts, however, would provide no moral escape, since they would create beings without meaning. Arguments seeking to justify ending the lives of others need some grounding in concepts of the meaning of a life. The euthanasia discourse therefore needs to take at least some account of the meaning we construct for our lives and the lives of others.     

ATTENTION TRAINING: THE USE OF OVERCORRECTION AVOIDANCE TO INCREASE THE EYE CONTACT OF AUTISTIC AND RETARDED CHILDREN

A crucial first step in teaching and training the retarded and autistic is to develop and maintain eye contact with the therapist. Functional movement training (an overcorrection procedure) plus edibles and praise were compared with edibles and praise alone as a method of developing eye contact in three such children. In both conditions, the child was given food and praise when eye contact occurred within 5 sec of the therapist's verbal prompt: “Look at me.” Functional movement training avoidance plus edibles and praise produced about 90% attention for the three children, while edibles and praise alone were less effective (eye contact never exceeded 55%). Functional movement training avoidance combined with edibles and praise appears to be an effective method of teaching eye contact and possibly other forms of instruction-following to behaviorally disordered children who are not always responsive to positive consequences.     

汉语句子-图片信息整合的眼动测量

采用眼球追踪-分析法考察了“句子-图片”验证范式下句图信息整合过程中句式和语义关系类型的作用。实验结果表明：（1）汉语句子-图片信息整合过程中,句图继时呈现没有消除语义失配效应,注视次数、总注视时间显著增加,瞳孔直径扩大。语义失配会显著干扰句法难度低的句式的句图信息整合。（2）句式影响句子-图片信息的整合过程,注视次数、总注视时间、瞳孔直径随句法难度增加而增加。（3）汉语句图信息整合过程中,语义失配效应受句式影响,表现出任务的特异性,这说明成分比较模型不具有一般性
