The British Army Recruit Battery Goes Operational: From Theory to Practice in Computer-Based Testing Using Item-Generation Techniques

The British Army Recruit Battery (BARB) was commissioned in 1986 by the Army Personnel Research Establishment (APRE) under a mandate from the Directorate of Army Recruiting as part of a programme of strategic research. Item-generation from computer algorithms and computer delivery of the battery are the two fundamental building blocks of the BARB system and they are described in detail. In addition, reports of the psychometric properties of the battery and the results of validity studies are provided. A true score model of reliability is outlined and its utility demonstrated by comparing predicted reliabilities against operational test–retest reliabilities.     

An introduction to the PLATO CAI system

The PLATO interactive computer system is discussed as a fully developed large-scale CAI system. Both the hardware and software aspects of the system are discussed. The discussion of hardware includes the necessary equipment to operate a PLATO system and the flow of control during an interactive session on that system. The discussion of the software on the PLATO system focuses on the TUTOR lesson-authoring language. The aspects of the TUTOR language that facilitate display of material, student input and judging of input, and either student-initiated or author-initiated branching in the program are discussed.     

Applications of the PLATO computer system to research in social psychology

The use of the PLATO CAI system in psychological research is discussed. This discussion covers the use of the PLATO system for research in personal space, attribution, person perception, and group decision making. The aspects of the PLATO system that facilitate research in each of these topic areas are discussed in detail. Further modifications of the PLATO system that would enhance its applicability to psychological research are also discussed.     

Reliability of the Attitudes Toward Women Scale (AWS) and the Personal Attributes Questionnaire (PAQ)

The stability and internal consistency of Spence and Helmreich's Attitudes Toward Women Scale (AWS) and Personal Attributes Questionnaire (PAQ) are reported. An entire first-year class of 1,007 male and 78 female cadets at the U.S. Military Academy were given a battery of psychological tests before and after cadet basic training, a 2 1/2-month period. The AWS and PAQ proved to be highly reliable, comparable to other frequently used psychological tests. This psychometric information encourages researchers to make further use of these gender-related instruments.This research was conducted under research grants from the Army Research Institute (Alan G. Vitters and Jerome Adams, Principal Investigators).

Some Lasting Consequences of US Psychology Programs in World Wars I and II

Applied research in psychology not only has contributed directly to societal advances but often has fostered basic research as well. Prominent examples are the programs directed by Yerkes in World War I to develop the Army Alpha test and several programs in World War II, including The American Soldier that assessed soldiers' attitudes during the war; a program for selecting agents for the Office of Strategic Services; and the Aviation Psychology Program to select and classify applicants for flight training in the Army Air Forces. Highlights of these programs are presented here, with special attention given to by far the largest, the Air Forces program. After World War II, many of the hundreds of psychologist veterans became prominent research psychologists. Most became university professors. Among those who continued to work in applied settings was John Flanagan who had served as Chief of the Army Air Forces Psychology Branch. (After the war, Saul Sells succeeded Flanagan as Head of the Aviation Psychology program.) Flanagan founded the American Institutes for Research (AIR), the earliest mission of which was to select flight personnel for civilian airlines. Another part of the AIR mission was to enhance civilian air safety by assuring the widespread use of Flanagan's critical-incident procedures (or near-accident reports) that now serve to reduce accident rates in a variety of industries as well as in aviation.     

Women in the United States Army

This article addresses the recent increase in the utilization of women in the United States Army. It traces the history of women in the Army from the turn of the twentieth century to the present and recounts research (both published and unpublished) concerning (1) attitudes toward the use of women in the Army, (2) the impact the changing role of women has had on the Army's ability to perform its mission, and (3) the adjustment of women to the Army. Finally, the author speculates about the future of women in the Army.This article is a revised version of a paper presented at the meeting of the Southwest Regional Conference Inter-University Seminar on Armed Forces and Society, Dallas, April 1978. This paper was written while the author was a Research Scientist at the U.S. Army Research Institute for the Behavioral and Social Sciences.

Large sample validations of three general predictors of pilot training success

This article addresses one of the perennial problems of pilot selection research: obtaining an adequate sample size for reliable statistical analysis of predictive validity. Results from three studies involving the same computerized tests of instrument comprehension and psychomotor ability were combined in a meta-analysis to determine whether the validities of these tests generalized across three contexts. These were Royal Air Force and Turkish Air Force fixed-wing pilot training and British Army Air Corps rotary-wing pilot training. In this article, we discuss the adequacy of samples for estimating the validity of the tests, and the persistence of predictive validity to later stages of training as shown by British Army Air Corps data. Reference is also made to data from a fourth independent study of Qantas pilot training.     

AN OVERVIEW OF THE ARMY SELECTION AND CLASSIFICATION PROJECT (PROJECT A)

This paper serves as an introduction and background for the remaining papers in this issue, which describe in somewhat more detail the major pieces in the Army's Selection and Classification Project (Project A). The principal objectives, the methods being used, and the basic research design of Project A are outlined. Project A was a 7-year effort conducted by the Army Research Institute and a consortium of three research firms. The overall objective was to generate the instrumentation and validity information data base that are necessary for modeling and developing an organization-wide selection and classification system. Both the scientific and practical implications of the project are noted.     

Problems in the evaluation of PLATO lessons

The evaluation of the effectiveness of PLATO CAI in both educational and industrial settings is discussed. The evaluation of the PLATO instruction in the educational setting generally supports the effectiveness of PLATO instruction but was hampered by limited control of instructional method for different populations of students. Further difficulties in evaluation were caused by ceiling effects in the measurement instrument. Evaluation of PLATO instruction in the consulting setting was hampered by lack of cooperation by the client institution. Mastery of the content of some areas covered by the PLATO lessons in this setting was high, whereas mastery of other content areas was low. Conclusions address the necessity for at least a minimal amount of cooperation from the client institution and a minimal amount of control of the evaluation setting for adequate evaluation of any CAI instructional method.     

The categorization of sentential contexts

A new experimental method, involving the sorting of linguistic contexts, is shown to be effective in discriminating the contexts of polysemous words as well as the contexts of synonyms of those words. These results are interpreted as support for the claim that the method of sorting linguistic contexts is a valid technique for studying the contextual information available to support inferences about word meanings.The research reported in this article was part of the author's work submitted as a doctoral thesis to Princeton University. It was supported in part by Contract MDA 903-86-K-0242 between the Army Research Institute and Princeton University.

Solution of the personnel classification problem with the method of optimal regions

The personnel classification problem is identified mathematically with other problems in the social and biological sciences. This mathematical problem is shown to be a special case of the general mathematical problem of linear programming. It is proposed here that the personnel classification problem may be solved directly by methods particularly appropriate to it as well as by the simplex method, which is a standard method for solving the general linear programming problem. The method of optimal regions is derived and illustrated in this paper.Much of the basic research covered in this paper was carried out while the author was working on the problem of personnel classification in his capacity as Consultant, Personnel Research Branch, Adjutant General's Office, Department of the Army. Some of the material was presented in a conference which was held at Personnel Research Branch in August, 1952. The author wishes to express his appreciation to the Department of the Army for permission to use these materials in this paper.

Virtual reality goes to war: a brief review of the future of military behavioral healthcare

Numerous reports indicate that the incidence of posttraumatic stress disorder (PTSD) in returning OEF/OIF military personnel is creating a significant healthcare challenge. These findings have served to motivate research on how to better develop and disseminate evidence-based treatments for PTSD. Virtual Reality delivered exposure therapy for PTSD has been previously used with reports of positive outcomes. This article details how virtual reality applications are being designed and implemented across various points in the military deployment cycle to prevent, identify and treat combat-related PTSD in OIF/OEF Service Members and Veterans. The summarized projects in these areas have been developed at the University of Southern California Institute for Creative Technologies, a U.S. Army University Affiliated Research Center, and this paper will detail efforts to use virtual reality to deliver exposure therapy, assess PTSD and cognitive function and provide stress resilience training prior to deployment.     

Behavioral sequelae of exposure to high power microwave fields

Behavioral sequelae of exposure to high peak power microwave pulses, similar to those produced by operational radar systems and experimental, directed energy weapons systems, were studied using rats trained on fixed-ratio, variable-interval, and differential reinforcement-of-low rate schedules. Ten minute exposures to 240, 720, 2160, and 6480 pulses at a 1 Megawatt peak power level caused a rectal temperature rise of 0.7 to 2.5°C in the animals. Regardless of their schedule of reinforcement, animals exposed to the highest dose level failed to respond, on the average, for 13 minutes after the exposure when they were placed in operant conditioning chambers. However, as soon as their rectal temperatures decreased, responding resumed and no further changes in response pattern were exhibited. No long-term effects were observed in exposed animals. Thus, the behavioral effects that were seen were thermal in nature and independent of the pulsed nature of the fields. This research was supported by the U.S. Army Medical Research and Development Command under the contract # DAMD 17-85-C-5083 awarded to ERC BioServices Corporation and was conducted at Walter Reed Army Institute of Research, Department of Microwave Research. The research was conducted in compliance with the Animal Welfare Act and other Federal statutes and regulations relating to animals and experiments involving animals. This study adheres to the principles stated in theGuide for the Care and Use of Laboratory Animals, NIH publication 85-23.

Women at west point: A three-year perspective

A longitudinal study of approximately 3,700 male and 300 female cadets investigated similarities and differences of these young adults during the first three years of coeducation at West Point. Both men and women were relatively homogeneous on comparisons of personality variables. Also, when personality characteristics were correlated with two psychological scales—the Personal Attributes Questionnaire and the Work and Family Orientation Scale—males and females appear more similar than different. Despite their similarities, female and male cadets were different in their attitudes towards the rights and roles of women in society, their leadership evaluation ratings, and their attitudes toward dating relationships. The implications of these findings in increasing our understanding of sex roles and sex stereotypes are discussed.This research was supported by research grant #MDA 903-78-GO2 from the U.S. Army Research Institute for the Behavioral and Social Sciences, Major Jerome Adams, principal investigator.

Strategic behavior in monkeys

In a recent paper, Lee et al. examined adaptive decision-making processes by training monkeys to play a competitive game against a computer programmed to play using various strategies. They found that the monkeys' responses were sensitive to the computer's strategies and consistent with reinforcement learning. Research such as this strongly complements current research in behavioral economics. We propose some potential future directions for this work, and put forward conjectures about what might be learned about decision-making in humans.     

PC-Based Game Features That Influence Instruction and Learner Motivation

PC-based games are currently being used for military training, but the instructional and motivational features of such technology are not well understood. To identify features of training games that influence instruction and motivation, a popular first-person-perspective game with a military theme was analyzed empirically. Twenty-one participants played the “basic training” portion of the game, which included Army background information, virtual marksmanship training, an obstacle course, virtual weapons familiarization, and an urban terrain training mission. The results of this research provide useful information to individuals developing training games, desktop simulations, and interactive multimedia courseware to meet optimal training objectives and strategies.     

The shifting salience of valence and instrumentality in the prediction of perceived effort,satisfaction and turnover

The role of valence and instrumentality was examined in predicting three work-related criteria in a military setting: satisfaction, perceived effort, and turnover. A total of 323 enlisted men responded to desirability and instrumentality scales for each of four categories of performance outcomes: extrinsic rewards, personal fulfillment, recognition, and autonomy. Multiple regression analyses indicated that the different outcome types varied substantially in their relationship to the criteria, ranging from strongly positive to no relationship to strongly negative. Furthermore, the salience of valences and instrumentalities changed as a function of the criterion being predicted in a manner not deducible from current expectancy-valence models. Several implications of the results were discussed in terms of assumptions underlying general expectancy-valence approaches to motivation.This research was supported in part by Grant DAHC19-77-G0017 to New York University (Samuel Shiflett, principal investigator) from the Army Research Institute for the Behavioral and Social Sciences.

Personal Performance Plan: Application of Mental Skills Training to Real-World Military Tasks

Recently, several authors have discussed the potential benefits of interdisciplinary cooperation between the military and the field of performance psychology. The purpose of this article is to build upon their suggestions by presenting a phased approach to mental skills training grounded in performance, learning, and military literature that can be applied to a wide variety of military tasks. After discussing the basis for the model's content, structure, and training approach, details of the mental training protocol are provided, a case example involving Army Infantry Soldiers is presented, and directions for future research and lessons learned are offered.     

Crimes and Punishment: Blacks in the Army’s Criminal Justice System

Are Blacks discriminated against in U.S. Army courts-martial? This article reviews the literature and presents original research to address this question. Other topics examined include the overrepresentation of Blacks in the Army courts-martial and soldiers’ perceptions of the fairness of the justice system. I examined all aggravated assault charges heard in Army courts-martial during a 6-year period and found several striking differences. White defendants are far more likely to have a pretrial agreement (i.e., plea bargain) than are Blacks (69% vs. 51%), and hence, Whites are more likely to plead guilty (87%) than are Blacks (72%). These same patterns are found when all courts-martial, regardless of offense, are analyzed for the same 6-year period. Once a defendant enters the Army courts-martial system, there is no statistical evidence of discrimination. If discrimination occurs in this process, it will occur where commanders have greater discretion (e.g., for less serious offenses, prior to deciding on courts-martial). Suggestions for further research are offered.
