Modrick, John A., Meyers, Susan and Papke, Robert (1995): Distribution of Discretionary Time by Retired People. In: Proceedings of the Human Factors and Ergonomics Society 39th Annual Meeting 1995. pp. 163-166.
“This study is a survey of the activities of retirees of a Fortune 500 manufacturing company. The objective was to provide a baseline description of activities as people adjust to changes associated with retirement and decremental changes of aging. A sample of 40 retirees was interviewed to obtain information on 1) demographics, living conditions, and health; 2) distribution of time over activities of work, recreation, family, and volunteering; 3) changes associated with aging and socio-economic factors. It is intended to provide an activity picture that will be a context for identifying behavioral problems and devices, organizations, and supporting aids to enhance quality of life. Respondents represent the gamut of occupations and skill levels, socio-economic conditions, and ethnic diversity characteristics of a large, midwestern manufacturing corporation. The distribution of ages in the retiree population and sample were equivalent. The activities surveyed include reading, watching television, household chores and maintenance, skill or craft hobbies, intentional exercise, care-giving, volunteer work, and work for pay. Analyses include differences and changes in activities as a function of gender, age, length of retirement, health, and living situation. Volunteer work is analyzed in detail concerning type, location of the work, and time spent on it.”

Modrick, John A. (1993): Toward a Conceptual Model for Measurement and Evaluation of Tactical Performance of GNUTs: Groups, Networks, Units, and Teams. In: Proceedings of the Human Factors and Ergonomics Society 37th Annual Meeting 1993. pp. 1171-1175.
“The objective of performance measurement is to assess the operational effectiveness of an individual or unit: use of resources to accomplish operational objectives. A continuum of collectives from groups to teams on the basis of organizational attributes is proposed. A shared plan of operation is proposed as the organizing agent of collective performance. Tactical decision making is defined in the context of adaptive problem solving. Although decisions are implemented as procedures, the procedures must be improvised in the situation and adapted to local conditions. Tactical Procedure Scripts are proposed as a structure for organizing performance data into operationally meaning segments for analysis, evaluation, and after action review. Operational and functional processes of GNUTS are differentiated and a three level process model is outlined. A domain model for tactical decision making and the use of behavioral objectives in a test plan are discussed.”

Modrick, John A. (1992): The Role of Complexity in Human Performance, Memory, and Training. In: Proceedings of the Human Factors Society 36th Annual Meeting 1992. pp. 1163-1165.
“The objective of this symposium is to discuss research dealing with the role of complexity in functions and tasks commonly allocated to the operators/users of systems. Systems of greater capability are being designed and the complexity of operation is increasing. Conceptual/experimental approaches to complexity are reviewed under the categories of procedural, cognitive, and conceptual complexity. Specific projects are reviewed on the effects of complexity on memory for procedures, information extraction for displays, and flight operations in the glass cockpit.”

Modrick, John A. (1992): Review of Concepts and Approaches to Complexity. In: Proceedings of the Human Factors Society 36th Annual Meeting 1992. pp. 1166-1170.
“The objective of this paper is to review research dealing with the role of complexity in functions and tasks commonly allocated to the operators/users. This topic is complex and not well-structured. We have reviewed principal approaches to provide better structure for the psychological domain of complexity. The research reviewed is partitioned into three categories: procedural, cognitive, and conceptual complexity. What we were after in the review was to find quantifiable attributes of complexity in cognitive tasks and skills and how to use these attributes to manage complexity during system design.”

Modrick, John A. (1991): A Conceptual Framework for Classifying and Measuring Cognitive Skills. In: Proceedings of the Human Factors Society 35th Annual Meeting 1991. pp. 1288-1292.
“A framework is presented for classifying the cognitive skills exercised in deploying and managing resources in competitive situations. Behavioral task descriptions are partitioned into four cognitive levels: functions, procedures, skills, and abilities. A cognitive procedure is defined as a goal-directed, semi-structured, flexible sequence of actions in an emergent situation, adapted to deviations from nominal values for local conditions, terrain, environment, and adversarial actions. A procedure is represented as Cognitive Procedure Script (CPS), a sequence of actions required to achieve an operational goal. Actions in a CPS must be reduced to detectable response/event sequences for carrying out the actions: Implementing Steps (IS). To infer a candidate CPS being executed a computer maintains a temporal record of IS and searches for patterns that correspond to an action in a CPS. The CPS is represented also as a sequence of states and subgoals instrumental to a final goal. Each state is defined by situational conditions, subgoal, state maintenance behavior, action to transition to the next state, and the IS for executing the action. Implications for task analysis and measures of task complexity are discussed. A long range strategy is presented for developing and validating a Cognitive Skills Taxonomy to support decisions about manpower, personnel, and training during system design.”

Chambers, Randall M., Hendrick, Hal W., Koonce, Jefferson M., Modrick, John A., Schopper, Aaron W. and Senders, John W. (1990): Critical Issues and Developments in Graduate Training and Continuing Education in Human Factors. In: D., Woods, and E., Roth, (eds.) Proceedings of the Human Factors Society 34th Annual Meeting 1990, Santa Monica, USA. pp. 520-521.
“Considering the variety and sources of graduate training and continuing educational programs which lead to the science and professional practice of human factors, this panel identifies and discusses important issues and developments in the training and education of human factors specialists. Then it recommends appropriate and professional solutions and approaches to these issues from the perspectives of universities and other institutions which are engaged in human factors training and education, research and application, and the professional practice and utilization of human factors. In the training and education of human factors specialists, there are important professional and scientific issues which may be examined as the human factors discipline progresses toward accreditation and certification, and new developments and accelerated growth continue to increase professional competence and social responsibility.”
