 | Groups performing complex tasks under operational conditions can be anticipated to undergo changes in size and membership. Accordingly, the research project developed a paradigm for investigating the effects of such membership turbulence with 2- and 3-person groups residing in a programmed laboratory environment for 10 successive days. A range of mission parameters (e.g., performance tasks, motivation, group gender composition, social interaction opportunities, etc.) was systematically explored during 10 studies that ... |

|
| This report reviews a research program undertaken within a laboratory environment that was designed and constructed to support behavior analyses of individual and group performance effectiveness viewed conceptually within the context of a small-scale human microsociety. Summarized are previous research emphases and findings in relationship to (1) conditions that sustain group cohesion and productivity and that prevent social fragmentation and performance deterioration, (2) motivational effects resulting from the programmed consequences ... |

| This report reviews the background, objectives, methodology, and results of a research project devoted to (1) the development of principles and procedures relevant to the selection and training of sea/space mission personnel, (2) the investigation of preventive monitoring and corrective procedures to enhance sea/space mission performance effectiveness, and (3) the evaluation of countermeasures to the potentially disruptive effects of unfamiliar and stressful environments. Initial research endeavors were directed toward the ... |

|
| This report presents a description of a programmed environment research laboratory that was designed and constructed to support functional analyses of individual and team performance effectiveness viewed conceptually within the context of a small-scale microsociety. The technical and organizational merits of a behavioral program, which structures team members' use of resources in a disciplined yet meaningful way, are suggested as a promising solution to the problem of motivating and monitoring ... |

|
| In Experiment I, hour-long elevations in men blood pressure were elicited by the performance of a synthetic work task for both naive subjects and experienced subjects. Task-elicited changes in heart rate failed to reach significance although split-half reliabilities of both heart rate and mean blood pressure were high during task performance. Significant correlations were observed between performance effectiveness and cardiovascular response magnitude that differed in sign between experienced and naive ... |

|
| Three volunteers lived for six successive days in a laboratory programmed for continuous residence. When work on a multiple task performance battery had the effect of preventing a reduction in accumulated team earnings, all subjects complained, one subject stopped working, and another subject's productivity declined. When identical work had the effect of incrementing team earnings, by-products of aversive control were absent. (Author) |

|
| Summarized herein are the results of a three-year research program, encompassing the period from 1 July 1977 through 30 June 1980, that focused upon an experimental analysis of the interacting motivational and social factors which influence performance effectiveness in small groups under conditions of continuous residence and observation in a closed ecological environment. Studies were conducted with three-person groups of human volunteers over extended periods in a residential laboratory which ... |

|
| An interbehavioral analysis is provided as the basis for a unifying operational framework encompassing motivational and emotional functions. Within this context, a research environment has been designed for the conduct of small group experiments in a self-contained laboratory programmed to provide individual and social work and recreational opportunities during continuous residence by volunteer human subjects over extended time periods. Initial studies with groups of two or three individuals served to ... |

|
 | A minicomputer controlled battery of tasks is provided which can be presented individually or in combination on a single peripheral device, a cathode ray tube (CRT), and which uses the accompanying keyboard as the operator's console. The battery is composed of the following five tasks which represent major dimensions of complex human performance: probability monitoring, arithmetic operations, target identification, warning light monitoring, and blinking light monitoring. This system shows that ... |
