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.     

延迟命名任务中图词干扰效应的眼动研究

采用图-词分离呈现及眼动技术探讨在延时命名条件下图-词干扰效应发生的位置。结果发现：（1）延时命名图片时,仍出现图-词干扰效应和频率效应;（2）与命名干扰词相比,命名图片时图片的回视率高,注视时间长;（3）图片的注视时间也出现频率效应和图-词干扰效应。这说明即使在延时命名图片的条件下,目标词汇仍需要再次激活,频率效应和图-词干扰效应是发生在词汇化过程中,反驳反应排除理论的图-词干扰反应选择阶段的观点,支持了词汇化选择竞争的理论。     

大学生词的获得年龄、熟悉度、具体性和词频效应的眼动研究

采用眼动实验方法,研究大学生词的获得年龄、熟悉度、具体性和词频四个变量在句子阅读中所产生的字词识别效应,以及效应作用的时间进程。对这四个变量与词阅读的首次注视时间、单一注视时间、凝视时间、总注视时间进行多元重复回归分析,结果发现,词频和熟悉度在词识别过程的所有方面都具有重要性,获得年龄对词识别的早期加工过程敏感,具体性对各个阶段的词识别影响不显著。     

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。     

背景音乐的节奏与歌词语言熟悉程度对驾驶行为和眼动的影响

摘要：采用3D模拟驾驶情景结合眼动技术探讨音乐节奏和歌词语言熟悉程度对驾驶行为和眼动规律的影响,研究结果表明：（1）驾驶经验对驾驶行为及眼动影响显著,新手与老手相比速度更慢、错误数更多;（2）音乐节奏对驾驶速度、眼跳和垂直搜索广度影响显著,快节奏与慢节奏相比,驾驶速度更快、平均眼跳距离更短、垂直搜索广度更短;（3）歌词语言熟悉程度对驾驶速度、错误数和平均注视时间影响显著,熟悉语言与陌生语言相比,驾驶速度更慢、错误数更多、平均注视时间新手更长,老手无影响。（4）节奏与语言共同影响驾驶过程中的水平搜索广度,陌生语言时快节奏的水平搜索广度高于慢节奏,熟悉语言时快节奏的水平搜索广度低于慢节奏。通过本实验,建议驾驶员在选择音乐时选择陌生语言歌词的音乐,音乐节奏则可视情况而定。     

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.     

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.
