Computer use by the visually impaired

Several recent developments have made computers accessible to the blind and partially sighted: hard-copy (paper) and softcopy (raised-pin) braille output, magnified high-resolution characters, and synthetic speech. We report survey data on these users’ computer education, tasks, and goals; their hardware uses and preferences, particularly for special-purpose I/O devices; and seven classes of human-factors problems that affect the use of these I/O devices by the visually impaired.     

Turning Fantasies About Positive and Negative Futures into Self-Improvement Goals

Contrasting fantasies about the future with reflections on reality that impedes fantasy realization creates a tight link between expectations of success and forming commitments to self-improvement goals. This effect applies to both fantasies about a positive future contrasted with impeding negative reality as well as fantasies about a negative future contrasted with impeding positive reality. In Study 1, with 63 student participants, contrasting positive fantasies about benefiting from a vocational training with negative reflections on reality impeding such benefits led to expectancy-dependent willingness to invest in the training, more so than indulging in the positive future and than dwelling on the negative reality. In Study 2, with 158 high school students from former East Berlin, contrasting negative, xenophobic fantasies about suffering from the influx of immigrants with positive reflections on reality impeding such suffering led to expectancy-dependent tolerance and willingness to integrate the immigrants. Findings are discussed in terms of how mental contrasting facilitates self-improvement and personal development by making people form expectancy-dependent goal commitments to approach positively-perceived as well as negatively-perceived futures.     

Clutching at Certainty: Thoughts on the Coercive Grip of Cult-Like Groups

This response to Richard Raubolt's article, Attack on the Self, attempts to understand the intense and enduring connection that often develops between charismatic leaders of cult-like groups and their followers in terms of their mutual need to regulate uncertainty. After describing the intersubjective regulation of uncertainty, a concept influenced by self psychology and intersubjectivity systems theory, a number of uncertainty regulating modes that emerged in the training program are examined including: 1) the denial of difference, 2) the denial of sameness, 3) alter ego relating, 4) the inflamation of passion, and 5) faith-keeping fantasies.     

Alcohol in the Movies: Characteristics of Drinkers and Nondrinkers in Films From 1940 to 1989

We examined depictions of alcohol use in 100 popular films spanning 5 decades. Drinkers were depicted as more attractive, more romantically/sexually active, more aggressive, and having a higher socioeconomic status than nondrinkers. No systematic changes were found across decades that might reflect the growing knowledge base regarding the adverse effects of alcohol use. We compared the depiction of alcohol use in movies to real-world demographics and found that alcohol use in movies is somewhat glamorized.     

Assessing the winning teams program of interactive satellite-based training

This research assessed an interactive satellite-based training program integrating interactive audiovisual experiences with face-to-face interactions. Key elements were content created by experts, high-quality video segments, satellite-based interaction, off-line interactions among teams of parents and caregivers, workshops, and team building exercises. For pragmatic reasons, it was necessary to develop brief assessment instruments concurrently with training. A large set of survey items were created from draft materials and reduced empirically through piloting to those with the best psychometric properties. To avoid the appearance of traditional testing, knowledge was assessed with Likert items. Surveys measured participant satisfaction, knowledge, attitudes, and the application and articulation of concepts. Participant satisfaction was high. Participants increased positive attitudes and learned appropriate vocabulary. Training was more effective than no training or watching videotapes. The program appears to represent a viable model of training that could successfully be applied to Internet technologies.     

Computer use in cognitive psychology

Some influences of computers on theory and methodology in cognitive research are discussed. Theoretical constructs that cognitive science has borrowed from computer science include processing algorithms, processing rates, information organization, and information selection. The application of these constructs to human information processing is considered, with illustrations from memory and reading research. Further, the role of computers in research methodology is evaluated, on the basis of a comparison of 1962 and 1992 journal articles. Attributes considered include the nature of stimulus control, item content and physical features, cognitive task demands, information feedback to subjects, and assessment of individual differences in cognitive strategies. These methodological attributes are illustrated by memory and reading paradigms for which computer technology is critical. Computer science has enriched theory and data in cognitive science, but the comparison of journal articles from 1962 and 1992 suggests that many psychologists are not taking full advantage of these possibilities.
