A computer program to synthesize American Sign Language

A program is described that allows experimenters to generate American Sign Language forms by computer. The computer synthesis of such signs could allow major advances in the experimental investigation of the perception of sign language, much as computer-generated speech has done for the study of speech perception.     

A virtual terminal program for data transfer between a data general MicroNOVA laboratory computer and a DECsystem-10 timesharing system

A program for transferring data files between a small lab computer and a large timesharing system is described. The program is based on the concept of having the lab computer simulate a timesharing terminal. General features of the approach and the major implementation problems are discussed.     

Using computer conferencing to formulate a computer simulation of transitive behavior

The activities of a group engaged in simulation modeling via computer conferencing are described, and the model which resulted from those activities is briefly outlined. The phenomena which were modeled were initially described in a series of studies by Trabasso and his colleagues. These studies centered upon exhibition of transitive choices by children and adults, and supported the hypothesis that the choices were guided by formation of “linear arrays“ of the choice objects.     

Using the FORTH language in real-time computer applications

The FORTH computer language is described, with emphasis on aspects relevant to its use in the real-time control of psychological experiments via microcomputers. Among FORTH’s advantages are speed, compactness, and flexibility. Potential disadvantages include unusual syntax and lack of file-oriented disk access. Two sample FORTH-based systems are described.     

How to check a computer program

The usual ways of checking computer programs have important flaws. A better way to check a program you have written is to have someone else write a program that does the same thing and then compare the output of the two programs over a wide range of input. Two examples are described.     

The MicroAce: An inexpensive computer controller

A $200 computer system is described that can act as a laboratory controller. Advantages and disadvantages of the system are discussed.     

An interface for transmitting discrete response information to a computer

A circuit is described for interfacing response keys and other discrete inputs from psychological apparatus to a computer. Some of the unique features are: high noise immunity, the ability to transmit data over long distances, and electrical protection of the computer from accidental and potentially catastrophic high voltage inputs.     

Some experiments with computer synthesized speech

The generation of satisfactory artificial speech involves a great variety of semantic, linguistic, and articulatory factors. Many of these complex elements are as yet unknown, and computers are used extensively for their investigation. An account of an on-line, interactive computer facility used for such research at Bell Laboratories is given. The use of this facility for exploring the duration and pitch correlates of stress in English sentences is described.     

EDP (electronic data processing)-oriented special documentation in neurology--extension to a computer epicrisis

The contribution describes a final neurological documentation system for in-patients that permits the computerized print-out of an epicrisis. The computer automatically summarizes the elementary findings and presents them as a number of important neurological syndromes. The structure of the documentation and the experience gained in the course of many years of routine application are described. The system has proved to be basically sound under the conditions existing at a university hospital and a specialized hospital for psychiatry and neurology and has proved applicable for a large proportion of the patients without major restrictions.     

An inexpensive CRT terminal controller/computer

An inexpensive CRT terminal controller/computer is described. The board integrates virtually any keyboard and CRT monitor into a work station with firmware-governed intelligence. The system is designed to fill the cost/functionality niche below the Apple microcomputer. It can be configured as a dumb or smart terminal (approximately $100 plus keyboard and CRT monitor), as a self-contained computer that runs ROM-based software such as a small BASIC or an assembler/disassembler fan additional $100 in chips), or as a word processor if aa audio cassette ($50) or dual digital cassettes with controller ($125) are added.     

The Maxwellian optics laboratory automation using a personal computer

The Maxwellian optical system described here is fully automated in both experimental control for psychophysical instrumentation and data gathering using a personal computer (PC) with simple interfacing and input/output processing. The system features PC-based high-speed noise-free liquid-crystal shutter control, automated light control, glow modulator tube control, and filter/wedge control. PC-based data gathering and data transfer to the mainframe via RS-232C based Teloeom are described.     

A 6809 single-board computer system for the control of behavioral experiments

A computer system consisting of a 6809 single-board computer in conjunction with an IBM-compatible Personal Computer (PC) is described for the control of behavioral experiments. The single-board computer uses the C programming language to program experimental events. Each component of the system (the single-board computer, a digital interface, the PC, and the software) is outlined with its capabilities and drawbacks noted.     

A note on item analysis with an electronic computer

An electronic computer with large capacity memory, and employing binary numbers, is ideally suited for large-scale item analysis. The adaptation and use of one computer, SWAC, is described. A research project of the American Council on Education and The Grant Foundation.     

A large computer looks at the distributed computing problem

The various ways in which a large computer can be of service to a small laboratory processor are discussed. The Cambridge Project and the Consistent System (a collection of programs, models, and data) are briefly described.     

Psychological systems questionnaire: An objective personality test designed for on-line computer presentation,scoring, and interpretation

Previous research efforts to use on-line computer systems for personality assessment are briefly reviewed. Shortcomings in the conversion of paper-and-pencil testing forms to computer media are noted. Construction of a new instrument, specifically designed for use with an on-line computer system, is described. Advantages of this approach are noted.     

Variants of basic black computer interfaces

An input interface for connecting psychological apparatus to a process-control computer is described. It permits connection ofresponse switches to eliminate contact bounce and to provide interrupts on ongoing transitions of any data bit.     

A voice-activated key for the Apple Macintosh computer

An interface circuit to connect a microphone to an Apple Macintosh computer is described. The Apple Macintosh mouse port is used as the input port, and the microphone activation simulates a mouse press.     

Improved calibration of color video projectors by means of computer animation

A computer animation for the calibration of color video projectors is described. The animation facilitates the calibration procedure and can be readily programmed on almost any graphics computer or played from a videotape.     

Generalizing the problem definition step in the computer simulation of factorial experiments
