A hardware/software system is described that enables the TRS-80 Model I microcomputer to be used as a tachistoscope. The system synchronizes stimulus presentation with the 16.7-msec scanning rate of the cathode-ray tube. Hardware and software configurations for reaction timing and stimulus presentation are presented and discussed. 相似文献

When used in conjunction with a 6522 interface board, the Commodore 64 (C64) computer can control and precisely time externally generated stimuli. A C64-based experimental psychology laboratory that uses these capabilities is described along with a set of programs that can be used to control experimentation. The pros and cons of using the C64 as a laboratory computer are discussed. 相似文献

A machine language subroutine is proposed for measuring reaction time with millisecond accuracy using the TRS-80 microcomputer. This timer is accurate to 1 msec in the first 30,000 msec and to 5 msec in the first 65,000 msec (1 part in 10,000). 相似文献

A software package, MICROPLOT, was developed to run on a TRS-80 Model I microcomputer in conjunction with the Hewlett-Packard (HP) 7226 or similiar HP plotter. Capabilities include XY plotting of up to 10 data sets and curve plotting of an nth-degree polynomial. The package operates under the NEWDOS 80 Version 2.0 disk operating system but, with appropriate modification, can be run under any operating system that has dynamic program line merge and delete functions in BASIC. This report describes the structure of the system, hardware configuration, plotting capabilities, and applications in the behavioral laboratory. 相似文献

Procedures for reaction time research with 1-msec accuracy are described using the video display of the TRS-80 microcomputer. The LVB Corporation interface is also employed. Use of the cassette recorder as a voice key in this research is illustrated. A sample assembly language program is presented. 相似文献

For users who wish to program the TRS-80 microcomputer exclusively in BASIC, the FOR-NEXT timing loop provides almost twice as fine temporal resolution as the incrementing loop. A temporal resolution of 6.62 msec is possible with the FOR-NEXT loop. 相似文献

A machine language technique is described whereby the Z-80 microprocessor of the Model III TRS-80 can be programmed to monitor position of the electron beam during CRT scanning. This technique provides the opportunity to synchronize the appearance of video displays with Z-80 processing. The programmer can therefore be assured of crisp stimulus displays and precisely recorded reaction times. The computer’s real-time clock operates on video circuitry as part of a routine that is initiated by a maskable interrupt. The real-time clock interrupt can be vectored from its normal use to a routine that signals the Z-80 when the electron beam is at a known screen location. A machine language program and a TRSDOS BASIC program that demonstrate the technique are described. 相似文献

A system for on-line control of experiments is described that uses the Apple II microcomputer and requires no knowledge of programming. This system, APT, is used to construct test files, randomize stimulus order, and conduct experiments. Construction of an experiment is very easy through use of an interactive program. APT provides powerful options for controlling stimulus duration, feedback, and response type. Programs are available to conduct either a sequence of tests without any experimenter present or a single experiment. Over 200 subjects, ranging from 18 to 86 years of age, have completed a battery of cognitive and abilities tests using the system. 相似文献

This report compares currently available. Inexpensive (minimum stand-alone disk-based con-figuration under $2,000), mass-produced microcomputers from the viewpoint of their applicability as experiment control, stimulus generation, and data collection devices for the experimental psychology laboratory. 相似文献

The Radio Shack color computer is examined from the viewpoint of capabilities needed to program, time, control, and acquire data from typical cognitive psychology experiments. Its capabilities are compared with those of the alternative inexpensive microcomputers discussed in an earlier article (Reed, 1980). The paper also includes a 6809 assembly language routine that permits the measurement of reaction times in video horizontal scan (HS = 4/63 msec) units without hardware modifications and an RSCC BASIC program for unbiased conversion of HS units to milliseconds. 相似文献

A survey of the On-Line Psychology DEC Users’ Group was taken to evaluate DEC’s performance in the psychology research laboratory. Data were obtained for 20 rating scale items and 7 open-ended items in five categories. On a 10-point scale, DEC averaged about 6 on purchasing procedures and documentation, about 4 on delivery time and maintenance service, and about 7 on product satisfaction. The open-ended items provided users’ explanations for the ratings and new hardware and software that users would like to see from DEC in the near future. 相似文献

This course is structured as a series of increasingly difficult projects which involve students in all aspects of using computers for experimentation. Projects range from programming simple experiments utilizing monitor displays and keyboard responses to the use of hardware interfaces to connect complex peripherals. Students not only design and develop their projects, but also engage in data collection and analysis. The course provides experience with hardware and software as well as the intricacies of debugging the resulting project. 相似文献
