Projects in experimental psychology: Software for several classical perception experiments

Projects in Experimental Psychology (Sorkin, 1997) is a Windows-based series of nine classical perception experiments. It is primarily designed for laboratory use in perception and related courses. The program is generally simple to use and exploits the “point-and-click” features of Windows quite well. It complements, rather than competes with, Levy and Ransdell’s (1998) Laboratory in Cognition and Perception, which is more suitable for courses in memory. Projects can be extremely useful in laboratory courses in perception and cognition, although the number and range of studies may presently be too limited to be the exclusive source of data in these courses. Although instructors proficient with experiment generators such as MEL (Schneider, 1998) or ERTS (Beringer, 1992) may opt to design their own experiments, this is an excellent alternative for those who lack the time or the background to do so.     

Teacher resistance to computer-assisted instruction

The need to introduce computers to a greater extent in teaching technology is discussed. Further, the potential importance of affective responses in the teacher’s acceptance of the computers is developed. A semantic differential scale was employed to measure preservice teachers’ attitudes toward the computer, computer-aided instruction, science, mathematics, and the teaching of science and mathematics. Considerable negative affect was found toward computers, computer-aided instruction, and teaching of science and mathematics. Implications for the ways in which computer-aided instruction is introduced are discussed.     

Computer use in psychology instruction

This paper presents the ways in which psychology departments are using microcomputers for instruction, the types of facilities that they are using, and the varieties of hardware that they employ. These data are related to other data reported over the past 10 years. In addition, a summary of the types of software currently available in all areas of psychology is presented, and areas in which there is a need for further software development are identified. The information reviewed in this paper was compiled from the current software listings available through COMPSYCH, as well as the results of a survey distributed to registered users of COMPSYCH who hold academic positions.     

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.     

Problems with evaluation of courseware for instruction in psychology

Recent trends in courseware evaluation have stressed the importance of program characteristics ancillary to the learning process, such as the use of menus. Although attention to these aspects of programming may improve the appearance and ease of use of software, the primary consideration in the selection of instructional software is whether it can provide instructional content to the students who use it. This can best be determined by the instructor alone, who may often find it necessary to write programs to suit specific instructional needs. Such programs are in wide use and are often better than commercially available sets designed by professionals.     

Microcomputers for experimental psychology

The design and use of CPUs on a single inexpensive circuit are discussed. Necessary additional equipment is noted, and the potential for using the microcomputer in the laboratory is explored.     

Computer-aided instruction in a physiological psychology course

A simulation/tutorial sequence was introduced into an undergraduate physiological psychology class (N=32) to provide a laboratory experience. The college computer center managed the IBM-PC-compatible networked facility. The sequence included neuroanatomy, stereotaxic surgery, histology, electrical self-stimulation, and use of the polygraph. All the software was off the shelf except for the stereotaxic surgery/histology/self-stimulation package, which was written by the authors using ToolBook running under Windows.     

Empirical investigations versus anecdotal observations concerning anxiety in computer-assisted instruction

Empirical data are offered as counter evidence to the negative criticisms of Computer-Assisted Instruction systems as anxiety producing situations.     

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.     

Strains in experimental social psychology: a textual anaylsis of the development of experimentation in social psychology

A textual analysis of post-World War II social psychology methodology manuals and handbook chapters on "methods" indicates that the introduction of the experimental method was enforced and gradually strengthened through the use of scientific rhetoric and the minimization of alternative research strategies. As a consequence, by the 1960s experimentation had become such an established identifying feature of psychological social psychology that the acceptability of ideas in the field came to depend largely on the ability of authors to couch them in the language of the experiment. Text writers continually shored up the defenses of scientific legitimacy and denigrated all other types of argument. We explore three sources of tension or strains evident as contradictions in these texts: (1) between a rational experimenter's carefully following prescribed, logic-generated scientific practices and the investigator's artfully or intuitively designing research; (2) between social psychologists' missionary activities of proselytizing the experiment as the primary research method and social psychologists' apologies and insecurities expressed about using experiments; and (3) between the treatment of participants as docile and submissive versus portraying them as underhanded and damaging to the outcome of the research. In addition, we briefly reexamine the strain (4) between sober scientific experimentation and a playful "fun and games" approach to experimentation (Lubek & Stam, 1995).     

An overview of STEAMER: An advanced computer-assisted instruction system for propulsion engineering

We are building a computer-based instructional system for teaching the operation of complex physical mechanisms. The system is based intimately on the use of simulation. Our goal in this paper is to describe the system we are attempting to construct, discuss its origins, and identify what we perceive to be its implications for psychological research into instruction.     

An intelligent experimental station controller for human experimental psychology

The purpose of this paper is to describe the intelligent experimental station controller used in the extensible multiprogramming system for experimental psychology (EMPP) at the University of Washington. The EMPP system is an integrated hardware and software system designed to simplify the development of on-line psychological experiments. An intelligent graphics control system is one of the most important aspects of the system. The controller oversees the operation of eight independent experimental stations, each containing a cathode ray tube (CRT) terminal and a keyboard console. In addition to conventional computer interface functions, the controller contains an extensible hardware character generator which allows dynamic selection of the display character set. This paper describes both the hardware and software features of the system.
