ARIS: A computer-assisted instruction system

The automated real-time instructional system (ARIS) is a small computer-assisted instructional system written to run under the UNIX operating system on a PDP-11/34A machine. ARIS is a tool used to provide highly individualized instruction and, at the same time, to study the process of learning by keeping detailed records of students’ actions. Currently, the system is used to teach logic and set theory. This paper describes the general philosophy, operation, and implementation of ARIS.     

Software development for computer-assisted instruction in experimental psychology

The introduction of CAI modules was pursued as a means of strengthening an experimental psychology course. After securing 12 Apple II-Plus microcomputers and a Winchester hard-disk system, we turned to the search for and development of relevant software. Our efforts were initially frustrated due to several inadequacies in extant software that are discussed herein. A surprising source of software turned out to be the commercial market; two well known commercial programs have been modified for educational use, and one of these programs has provided a pleasant solution to student computerphobia. These two old modules are discussed, along with others that are either borrowed or new. Although total computerization has been avoided for reasons discussed herein, extensive evaluation has indicated that the modules have greatly facilitated the realization of course goals and have especially minimized the three complaints (irrelevant, boring, too difficult) most often heard in traditional research methods courses. In addition, our Attitude Toward Computers Scale indicates that students develop a more positive attitude toward computers as a result of their usage in the course. This positive attitude is seen as most adaptive in a society within which computers will play an increasingly dominant role.     

An automated system for primate instruction for behavioral neurophysiology

This paper describes a flexible hardware/software system developed for use with a PDP-8I computer for conducting research in behavioral neurophysiology. A real time monitor was designed to facilitate development, debugging, and modification of programs to run experiments. It relieves the programmer of the burden of dealing with hardware dependent functions such as interrupt handling and input/output. In addition, it provides the user with a large library of callable routines to perform functions commonly needed for conducting experiments. The monitor is modular in design and could be expanded or modified for use with many configurations of the PDP-8 family of computers.     

Theory of learning mathematics with computer-assisted instruction: Hierarchical and nonhierarchical options

The learning of arithmetic problems is assumed to be a Markov process involving conditioning of a set of k subskills, each consisting of one or more productions. An axiom set is provided, with the choice between two options for one axiom controlling which of two models results. Model 1, which assumes that every subskill is attempted on every occurrence of a given problem, is a nonhierarchical model. Model 2, which assumes that every subskill in the temporal sequence for a problem is attempted until one is failed, is a somewhat unconventional hierarchical model: It is hierarchical in the sense that conditioningor chance success at one level is prerequisite to performance of the next subskill (next level) in the problem. As the value of the guessing parameter, g, declines, Model 2 leads to less efficient learning than Model 1.     

A longitudinal evaluation of computer-assisted instruction on contraception for college students.

This study assessed changes in contraceptive knowledge of 58 white female undergraduate college students following use of a computer-assisted instruction (CAI) program on contraceptive methods. The CAI program consisted of a personal-computer-based instructional lesson covering facts about and appropriate use of oral contraceptives and barrier methods, and myths about sexuality and sexually transmitted diseases. Baseline contraceptive knowledge was first compared with 171 white female undergraduate students. This comparison indicated that, overall, there were knowledge deficits regarding the safety of oral contraceptives and what to do if oral contraceptives are not used correctly. At immediate posttest, significant knowledge gains were observed for danger signs associated with using oral contraceptives, the rationale for triphasic and biphasic pills, potential medication synergism, health benefits of using oral contraceptives, potential contraceptive effect of withdrawal, and the reasons women stop using the pill. At six-month follow-up, students evidenced long-term knowledge gains on duration of pill use, the rationale for triphasics and biphasics, appropriate contingencies for missing two days of the pill, danger signs associated with using contraceptives, medication synergism, and health benefits of using oral contraceptives. The results of the evaluation are considered in the context of the widely held assumption that young women's contraceptive failure is unrelated to knowledge deficits about methods of birth control.     

An Apple II package for computer-assisted telephone interviewing

This paper describes an Apple II (an Apple-compatible) microcomputer package for a computer-assisted telephone interviewing (CATI) system. This system generates random telephone numbers within any number of exchanges that the user supplies, automatically dials the telephone, prompts the interviewer with each question, and records and permanently saves each response. It also provides a printed copy of the collected data by frequency of response in each question category. The Apple II CATI package is readily available, inexpensive, and easy to program in the BASIC language.     

A minicomputer system for multiperson computer-assisted telephone interviewing

A computer-assisted telephone interviewing (CATI) system has been developed which has new and extensive implications for almost every phase of survey research. CATI provides (1) schedule design assistance, (2) new interviewing capabilities and controls which eliminate procedural errors, (3) coding assistance, (4) sampling administration, (5) interview supervision, and (6) postinterview data processing.     

The assessment of competency for execution: An overview

Competency for execution is a legal competency that is an integral part of the capital punishment process in the United States. With the rapidly increasing population under death sentence, the issue of competency for execution is likely to be raised with increasing frequency in the coming years. This creates some compelling ethical issues for the mental health professions. The questions of whether mental health professionals should provide assessment of competency for execution and, if so, how the assessment should be performed, are issues of immediate urgency.     

School phobia: An overview

This article discusses general features of school phobia and specific clinical and familial traits and characteristics. Included are overviews of theoretical explanations, types of school phobia, suggested methods of treatment, and their efficacy.     

Informed consent: An overview

Over the past 25 years, obtaining informed consent for the performance of many medical procedures has become part of the practice of medicine. As opposed to the “duty to warn” that is enforced by the law, informed consent should be a cornerstone of a fully collaborative decision-making process, the elements of which are presented in this paper. The responsibility for this process rests upon health care institutions and financing arrangements, as well as upon physicians and courts. In response to emergencies, patient preferences, and public interests, the consent process is justifiably abbreviated. However, as presently articulated, the consent process treats communication too simplistically, is distorted by the way it is enforced in litigation, is inattentive to social justice issues, and is not integrated into the moral commitment of physicians.     

Father-daughter incest: An overview

Conclusions describe the state of the art of current knowledge and suggest areas for research and theory development.     

Medical ethnomethodology: An overview

This paper gives a selective overview of studies in medical ethnomethodology. It starts with the 1967 contributions by Garfinkel and Sudnow, which focus on medical action as accountable Then it discusses the many CA-inspired studies of doctor-patient interaction published during the 1980s. Finally, it points to scattered studies that suggest several ways in which this latter approach can be deepened and enlarged. In this way, it formulates the contours of a program for ethnomethodological studies in the medical field.Revised draft of a paper read at the Conference: Ethnomethodology: Twenty Five Years Later,International Institute for Ethnomethodology and Conversation Analysis, Bentley College, Waltham, Mass. 13–16 August, 1992     

Behavioral economics: An overview

Behavioral economics is a new branch of the discipline which has become prominent only within the last decade. In spite of its short life span, behavioral economics has already produced insights into consumer behavior, the behavior of labor, managerial behavior and business ethics. The major findings are covered in this article.     

Organizational preparedness for change: Staff acceptance of an on-line computer-assisted assessment system

An on-line assessment system is briefly described. Previous positive evaluation studies are summarized. Results of studies of staff acceptance and staff preparedness for change are reported. Findings are interpreted in terms of the need for planning for change. Implications related to the acceptance of other on-line computer systems in psychology are discussed.     

Child of divorce: An overview

Children of divorce represent a diverse population at risk for subsequent psychological problems, whose interests are insufficiently understood or protected by the legal system or the mental health community. Although many children weather the stress of marital breakdown without psychopathological sequelae, a significant number show lasting difficulties. Information concerning the psychological adaptation of these children has increased rapidly during the past decade, but it remains unequel to the task of guiding family policy in this arena. Current knowledge identifies child gender and developmental stage as crucial factors that interact with the chronic stresses of postdivorce family life to produce short-and long-range impediments to the maturation of these vulnerable young people. There is a critical need to facilitate understanding and cooperation between the behavioral sciences and the legal profession on behalf of children in divorced families. The major research tasks relevant to enlightened public policy lie ahead.
