Effective Use

Emphasis upon more efficient and effective use of residual vision is vital to the rehabilitation process of visually impaired adults. Labels of blindness limit motivation to use remaining vision. Personal functional needs and degree of capacity are uniquely individual characteristics which must be taken into account in learning to use residual vision to best advantage. A continuing evaluation and application of new optical, technical, and medical-surgical techniques should be an integral part of services to adults with diminished vision.

Indoor And Outdoor

This article reports the results of a study to assess variations in the indoor and outdoor locomotor mobility of 22 low vision adults. Visual acuity, visual field, and contrast sensitivity data were obtained on all participants. Participants were also videotaped while walking unfamiliar indoor and outdoor routes under normal and reduced illumination. These videotapes were viewed by orientation and mobility instructors, who recorded such incidents as stopping or contacting objects during travel. Mobility assessment data obtained from the videotapes were analyzed in relation to type and degree of visual loss. Individuals’ visual fields and contrast sensitivities were found to be related to mobility performance, whereas their visual acuities were not. Visual field and contrast sensitivity together accounted for 39 percent of the variation in mobility performance. Results of the study are discussed in regard to the importance of visual contrast sensitivity and visual field for functional acitivities such as mobility.

And Training

This article discusses the need to develop ecologically valid measures of visual functioning and mobility performance in the context of current theories of perceptual functioning and learning, and describes the development of a visual assessment and training program, known as OCULA. An evaluation of the effectiveness of four tasks in predicting initial and final low vision mobility performance demonstrated that the tasks are better predictors of visual performance than are existing clinical measures and that learning can be transferred to real-life mobility situations. The results are interpreted in terms of differentiation theory, and the practical relevance of the approach to the training of low vision clients is emphasized, as is the potential of the system as a research tool.

Language Context

Purpose Although repetitive speech is a hallmark characteristic of autism spectrum disorder (ASD), the contributing factors that influence repetitive speech use remain unknown. The purpose of this exploratory study was to determine if the language context impacts the amount and type of repetitive speech produced by children with ASD. Method As part of a broader word-learning study, 11 school-age children with ASD participated in two different language contexts: storytelling and play. Previously collected language samples were transcribed and coded for four types of repetitive speech: immediate echolalia, delayed echolalia, verbal stereotypy, and vocal stereotypy. The rates and proportions of repetitive speech were compared across the two language contexts using Wilcoxon signed-ranks tests. Individual characteristics were further explored using Spearman correlations. Results The children produced lower rates of repetitive speech during the storytelling context than the play-based context. Only immediate echolalia differed between the two contexts based on rate and approached significance based on proportion, with more immediate echolalia produced in the play-based context than in the storytelling context. There were no significant correlations between repetitive speech and measures of social responsiveness, expressive or receptive vocabulary, or nonverbal intelligence. Conclusions The children with ASD produced less immediate echolalia in the storytelling context than in the play-based context. Immediate echolalia use was not related to social skills, vocabulary, or nonverbal IQ scores. These findings offer valuable insights into better understanding repetitive speech use in children with ASD.

Risk Taking Behavior

Abstract. Gender and personality traits influence risk proneness in the context of financial decisions. However, most studies on this topic have relied on either self-report data or on artificial measures of financial risk-taking behavior. Our study aimed to identify relevant trading behaviors and personal characteristics related to trading success. N = 108 Caucasians took part in a three-week stock market simulation paradigm, in which they traded shares of eight fictional companies that differed in issue price, volatility, and outcome. Participants also completed questionnaires measuring personality, risk-taking behavior, and life stress. Our model showed that being male and scoring high on self-directedness led to more risky financial behavior, which in turn positively predicted success in the stock market simulation. The total model explained 39% of the variance in trading success, indicating a role for other factors in influencing trading behavior. Future studies should try to enrich our model to get a more accurate impression of the associations between individual characteristics and financially successful behavior in context of stock trading.
