The CLIPR remote laboratory microprocessor system: Development and applications

The introduction of microprocessor technology into the centralized experiment automation facilities of CLIPR separates data processing functions and real-time functions. Three examples of real-time intelligent terminals are described. The implementation process, principles, and examples for using microprocessor technology in this way is described in some detail.     

The computer as experimenter in social psychological research

The effects of familiarity and exposure paradigm on evaluative meaning were investigated in four experiments involving 161 Ss. A DEC PDP-10 computer linked to a VB10-C display screen for 1/0 assigned Ss to condition, presented instructions, tested Ss’ understanding of the instructions, generated and displayed stimuli in various frequencies, and obtained evaluative ratings of the stimuli. Problems encountered, Ss’ reactions, and current and possible use of the computer in social psychological research are discussed.     

A computer lab for undergraduate psychological research

This paper describes how funds from an NSF Instrumentation and Laboratory Improvement grant allowed development of a computer lab with a local area network (LAN) for undergraduate research in psychology. The lab has been used mainly in conjunction with an applications of research methods course, but expanded use is expected because of the connection of the LAN to a mainframe computer’s LAN, the proposed installation of PSYCLIT on the LAN, and the proposed connection of the LAN to faculty offices. The main experimental software packages used are MEL Lab and Micro Experimental Laboratory (MEL); both are critical to the lab’s operation. Funds for maintenance of the lab will be obtained by charging applications course students a lab fee.     

Inexpensive plotters and digitizers for psychological research and instruction

The availability of low-cost microcomputers has been accompanied by the development of many inexpensive peripheral devices. The recent introduction of digitizers and plotters for use with microcomputers makes new research designs and instructional applications possible. This paper reports the characteristics and applications of one plotter and three digitizers of reasonably low cost. The application of digitizers in obtaining individual responses, quantifying data, preparing stimuli, and translating stimuli into machine-readable form is discussed. The application of plotters to hands-on instruction in data analysis and stimulus preparation is presented.     

The potential of HyperCard for psychological research and instruction: A general discussion and description of two research applications

In this paper, we discuss the potential of HyperCard for research and instruction in psychology. First we give a general overview of the HyperCard program; after that, we present two HyperCard stacks as sample solutions for two specific research applications. Surveyor, a self-contained survey tool, is a HyperCard-based vehicle for developing, administering, and processing tests and surveys. Queston demonstrates how HyperCard can be used as a data-management and data-analysis tool during the stages of questionnaire development. Both stacks illustrate how flexible HyperCard is and how easy it is to use it to manage, analyze, and process data, to transfer data to other programs, and to print reports. HyperCard, unlike traditional applications, gives the user a great degree of control over the way information is stored, mainipulated, and presented. Although both stacks are custom-made for specific purposes, the concepts underlying the design can be generally applied and adapted for other purposes.     

Input protection for the laboratory computer

Circuit details are given for building protective interfaces between laboratory instruments and a computer’s analog and digital inputs. The protective interfaces will not only protect the computer and its input interfaces from a misconnection, but they will themselves withstand misconnection with no damage.     

心理学研究中的可重复性问题:从危机到契机

可重复性问题是当前科学界面临的共同问题。最近,心理学研究领域的可重复性问题也受到广泛关注,引起了研究者的积极讨论与探索。通过对2008年发表的100项研究结果进行大规模重复实验,研究者发现,心理学研究的成功重复率约为39%,但该研究仍然存在着巨大的争议,不同的研究者对其结果的解读不尽相同。针对可重复性问题,研究者通过数据模拟、元分析以及调查等多种方法来分析和探索其原因,这些研究表明,可重复性问题本质上可能是发表的研究假阳性过高,可疑研究操作是假阳性过高的直接原因,而出版偏见和过度依赖虚无假设检验则是更加深层的原因。面对可重复性问题,研究者从统计方法和研究实践两个方面提出了相应的解决方案,这些方法与实践正在成为心理学研究的新标准。然而,要解决可重复性问题,还需要心理学研究领域的多方参与,尤其是在政策上鼓励公开、透明和开放的研究取向,避免出版偏见。心理学研究者为解决可重复性问题做出的努力,不仅会加强心理学研究的可靠性,也为其他学科解决可重复问题提供了借鉴,推动科学界可重复问题的解决。     

Social psychological research in The Netherlands, 1980-1988

This paper contains an investigation about research of Dutch social psychologists. Based on reported publications two types of analyses were performed. The reported publications were categorized by means of a topic-inventory proposed by Fisch and Daniel (1982), which enabled us to compare Dutch trends with developments in Europe and the U. S.A. Moreover, by means of bibliometric analyses publications of Dutch social psychologists were related to data obtained by the Institute for Scientific Information (ISI). Several trends were observed and discussed.     

A diagrammatic approach to computer instruction for the naive user

There are inherent difficulties with text as an instructional format. This research presents the development of a diagrammatic representation that overcomes some of those difficulties. A simple “language” is presented that includes both procedural and model information. This approach is applied to the instruction of word processing/text-editing skills. An experimental methodology is presented and preliminary results are reported that suggest that the diagrammatic approach results in improvements in both the amount of word processing accomplished and the speed with which modifications are made.     

The use of microprocessors in a timeshared computer facility for research,development, and teaching

The use of microprocessors in a timeshared computer facility at the Learning Research and Development Center, University of Pittsburgh, is described for applications in research, development, and teaching. Modes of usage are described, as are the advantages of microprocessor interfaces for on-line experimentation.     

The concept of adaptation-level in psychological research

Vuorinen, R. The concept of adaptation-level in psychological research. Scand. J. Psychol., 1973, 14, 228–240.- Helson's adaptation-level theory (ALT) is appraised as a general theory of psychology. The reformulated Fechner law underlying ALT is shown to be untenable and the conceptual status of AL is shown to be self-contradictory. The ambiguous measures and the inconsistent theoretical definitions proposed for AL are found to limit the scope of ALT. Reasons for its flexibility and claimed heuristic value are analyzed and potential sources of confusion are suggested. Some defects of ALT are likely to be shared by other behaviouristic theories since they follow from a commitment to the strict S-R model.
