Microcomputers in undergraduate laboratory training in psychology

Goals for undergraduate training in psychology are reviewed, and a survey is reported to suggest ways in which computers are being used to meet these goals. Currently computers primarily aid data collection and analysis. Computer-based literature searching and word processing are becoming more common. The true challenge of laboratory training, however, is inquiry training: helping students generate and frame research questions and interpret their results. Are we using the time we have gained through computer data collection and analysis to meet these goals? Are there ways in which the computer can directly help us meet these goals? The new generation of flexible experiment-generator software may provide direct help of this sort, as may effective simulations of theory.     

Instructional Uses of Microcomputers With Elementary Aged Mildly Handicapped Children

The goal of this article is to evaluate what we know about the instructional use of computers with young children and to suggest some priorities for their use with mildly handicapped children. While it is clear that computers can be programmed to provide effective instructions in a variety of skills, with mildly handicapped children they appear particularly suited to the delivery of highly motivational, speed oriented practice on basic academic skills in reading and math. Examples of currently available software are presented and evaluated in light of this priority, and needs for the future in terms of teacher training, service delivery systems, and hardware and software developments are disucssed.     

USING COMPUTERS TO DELIVER TRAINING: WHICH EMPLOYEES LEARN AND WHY?

Compared to traditional instructor-led training, computer-delivered training typically offers learners more control over their instruction. In learner-controlled environments, learner choices regarding practice level, time on task, and attention are expected to be critical determinants of training effectiveness. To examine the effect of learner choices in computer-based training, a study was conducted with 78 employees taking an Intranet-delivered training course. Learner choices were assessed and predicted with goal orientation (mastery and performance) and learning self-efficacy, as well as age, education, and computer experience. Results indicate considerable variability among trainees in practice level and time on task, which both predict knowledge gain. Performance orientation interacted with learning self-efficacy to determine practice level, and mastery orientation had an unexpected negative effect. Implications for the use of computers to deliver training and for future research are discussed.     

Using talking computers to remediate reading and spelling disabilities: The critical role of the print-to-sound unit

Talking computers employing computer-generated speech feedback have been used to remediate the literacy skills of dyslexic readers. A computer program is described that employs DECtalk, a highlevel speech synthesizer, to narrate instruction involving intensive training in identifying whole words or in identifying and blending word segments corresponding to onsets, rimes, and phonemes. Procedures for developing individualized instruction are described as well as for constructing and editing the speech and graphics features of the program. Neurologically impaired dyslexic children trained with this program achieved greater acquisition and transfer of word recognition skill when their training involved segmented rather than whole word feedback.     

Automated problem solving for the behavioral sciences

In view of the obvious advantages of computers for the behavioral sciences, the question is raised as to how to make more effective use of computing capabilities. One idea is to require that fledgling behavioral scientists receive brief training in flowcharting and algorithm generation rather than a full course in computing skills. Such training would be an important adjunct for those who would go on for further instruction, especially in view of current deficiencies in many computer courses. One recurrent deficiency lies in the lack of specific guidelines for conceptualizing problems for computer implementation. Such guidelines are developed here, along with other suggestions designed to attenuate the difficulty in conceptualization.

Computers in spatial vision research

The original impulse for using computers in a laboratory dedicated to spatial vision research and the current role of computers in experiments are detailed. Although computers are used widely for modeling spatial vision, there is some doubt about whether conventional serial computers are the most appropriate tools for this task.     

Social data analysis instruction and the MISSIS system

Social data analysis instruction is an enterprise providing experiences to develop problem solving skills. A proper focus upon analysis can best be provided with a data analysis package stressing simplicity rather than complexity. MISSIS is such a system, and it is designed to operate on small computers. Small technology can provide a training ground for making sound decisions in analyzing data.     

Stories About Counselors and Computers: Their Use in Workshops

Story-telling has been a traditional method of teaching new ideas and facilitating change. The author presents three fictional dialogues that demonstrate concerns regarding computers and counseling. Evaluation of these dialogues by participants in a computer training workshop is also discussed.     

Computer-based systems for applying psychological knowledge

Computer-based systems have long been seen as a means for applying psychological knowledge to instructing. However, from many years of research and development on instructional design and on using computers for instructing, we learned that the current instructional techniques are based on an inadequate scientific knowledge base and are poorly implemented. In order to do better, improved techniques based on modern cognitive science must be developed, and computer-based aids are needed to assist their application. Furthermore, a standardization and distribution system is needed to identify effective instructional programs and make them available. This seems especially important if we hope to have broad impact on education and training.     

Computer-aided reporting of the results of mental retardation evaluations

The MR Report Assistant is designed to perform the types of routine tasks that computers do well, while freeing the skilled psychologist to concentrate on tasks that are best done by knowledgeable humans. The Assistant is intended for reporting the results of psychological evaluation of known or suspected mental retardation patients using a standard battery consisting of the WAIS-R, the Vineland, and an interview. The program encourages the inclusion of additional information by writing to a disk file suitable for editing with a word processor, rather than directly to a printer. Research and training are encouraged by making the program available to qualified persons at no charge.     

The computer psychiatrist: How far have we come? Where are we heading? How far dare we go?

The use of computers in psychiatry and psychology is reviewed. It is noted that computers are already being used successfully for consultation, interviewing, and continuing education. Issues related to the usage of computers in mental health are discussed. Guidelines for future work in the area are suggested.     

Educational Trends for Expanding Women's Occupational Lives

Institutional changes are described which would facilitate the expansion of women's occupational lives. Part I reviews educational trends in schools, focusing on legislation and other activities to eliminate sex discrimination in federally supported educational institutions. Part II discusses current trends to interface education and work, and proposes a transitional work group model which incorporates feminist values and legitimizes the work place as a place for learning. Part III discusses trends towards participatory democracy and asserts that the training of women to use new technologies in communications and computers will increase their power to shape public policy. The conclusion points to the necessity for compensatory and anticipatory measures to ensure the representation of all groups of women in decision-making environments.     

Handwriting or Typewriting? The Influence of Pen- or Keyboard-Based Writing Training on Reading and Writing Performance in Preschool Children

Digital writing devices associated with the use of computers, tablet PCs, or mobile phones are increasingly replacing writing by hand. It is, however, controversially discussed how writing modes influence reading and writing performance in children at the start of literacy. On the one hand, the easiness of typing on digital devices may accelerate reading and writing in young children, who have less developed sensory-motor skills. On the other hand, the meaningful coupling between action and perception during handwriting, which establishes sensory-motor memory traces, could facilitate written language acquisition. In order to decide between these theoretical alternatives, for the present study, we developed an intense training program for preschool children attending the German kindergarten with 16 training sessions. Using closely matched letter learning games, eight letters of the German alphabet were trained either by handwriting with a pen on a sheet of paper or by typing on a computer keyboard. Letter recognition, naming, and writing performance as well as word reading and writing performance were assessed. Results did not indicate a superiority of typing training over handwriting training in any of these tasks. In contrast, handwriting training was superior to typing training in word writing, and, as a tendency, in word reading. The results of our study, therefore, support theories of action-perception coupling assuming a facilitatory influence of sensory-motor representations established during handwriting on reading and writing.     

Expected performance at the human/computer interface as a function of user proficiency and system power

How do managers expect the proficiency of users and the power of the computers to determine overall performance? Five different models are proposed: (a) a matching model in which optimal performance is achieved when the power of the system is judged to be compatible with the proficiency of the user, (b) an averaging model in which expected performance is the average of the values of user proficiency and system power, (c) a multiplying model in which performance is the product of the values of user proficiency and system power, (d) a human/computer ratio model in which performance is determined by the ratio of system power over total effort, and (e) a computer/human ratio model in which performance is determined by the ratio of user proficiency over total effort. The applicability of these models was assessed by having managers and students of management predict performance in human/computer systems from information about the user's proficiency with computers and the power of the system. Participants rated 16 combinations of user proficiency and system power from a 4 × 4 factorial design. The pattern of ratings indicated that 51 per cent used a multiplying model and 25 percent used an averaging model; whereas, only 6 percent used the matching model and 4 percent used a ratio model. The remaining 14 percent did not follow any model clearly. Implications of these results were discussed for the design of the human/ computer interface, training and selection of users, and the cost-benefit tradeoffs for investment in user training versus equipment acquisition.     

Issues in the effective use of computers in introductory and advanced courses in psychology

The recent proliferation of time-shared terminals, computers, and instructional software is producing a dramatic change in undergraduate education in psychology. Although computers have been used for many years in research in psychology, their use as instructional alternatives only recently has been thrust upon the academic community, a development for which many faculty-even experienced computer users—are ill prepared. The use of computers and microcomputers in instruction can provide the instructor, and more importantly, the student, with an effective pedagogical tool. However, computers cannot be introduced into the curriculum in a piecemeal or haphazard fashion. In this paper, issues involved in the effective introduction and use of computers in teaching are outlined.     

Internet-delivered assessment and manipulation of anxiety-linked attentional bias: Validation of a free-access attentional probe software package

It recently has been established within the laboratory that the attentional probe methodology not only can sensitively assess the threat attentional bias associated with anxiety vulnerability, but also can be configured to yield training tasks capable of modifying emotional vulnerability by manipulating such attentional selectivity. In order to appraise and exploit the potential practical applications of such procedures, it is desirable that clinical investigators without specialist equipment should become able to deliver such tasks within field settings. The present research program involved development of a fully customizable attentional probe software package, that delivers assessment and training versions of the probe task across the Internet. Two experimental studies served to validate the assessment and training efficacy of resulting probe task variants, completed remotely by GAD sufferers and nonclinical populations using their own computers. We advise fellow researchers how to freely download this software package for use within their own investigations.     

Ethical considerations in the use of computers in psychological testing and assessment

Ethical considerations in the use of computers in psychological testing and assessment are discussed. Particular attention is given to existing ethics and standards that provide guidance to users of computerized test interpretation and report-writing programs. Issues covering professional accountability and confidentiality are also discussed as they relate to computer-assisted assessment. Areas of appropriate use of computers in testing and assessment are suggested, including test scoring, the analysis of scores, and generating remedial recommendations. Findings are summarized and several guidelines are suggested for users of computers in testing and assessment.     

Hierarchically distributed processing for psychology

The advantages of loosely coupled hierarchical computer networks for psychological research are discussed. Hardware methods for interconnecting computers are considered, and software communication protocols are detailed. A hierarchy of interconnected computers is formed: (1) large campus computer for statistical analyses, (2) medium scale computer for data concentration and program development, and (3) laboratory computers for data collection. This hierarchy provides efficient computing at all levels and insures maximum computing power at minimum cost.
