On Adaptive Manual Control

Abstract: Experimental studies and control descriptions of the human operator in recent years have extended the knowledge of adaptive behaviour in manual control from vague generalities about his versatility to quantitative descriptions. Considerable data have been gathered on the ability of the human to adapt to changes in input spectra, controlled element gain, polarity and dynamics, display modality, and the limits of controllability under a variety of situations. These results have indicated a greater adaptation versatility than expected from some earlier descriptions, but have also pointed out some of the restricted training conditions under which the rapid human adaptation may be expected to be demonstrated. When it comes to explaining how the human manages his remarkable adaptation abilities, less progress has been made. Improvements in the techniques for dynamic measurement of the adaptive process have been helpful in this regard but still fall short of what is required to observe the change in control law. Some appealing suggestions for detection models, model reference conitrol analogues and statistical decision theory pattern recognition algorithms have been put forth but are in no sense 'proven'. Primarily as a result of the measurement limitation and the lack of sufficient knowledge about adaptive control systems in general, the development of models for human adaptive control has been limited to general schema at this time.

Migration and Adaptation: The Nature of the Problem

Abstract: This special issue is concerned with the human consequences, the sociobehavioral corollaries of migration. The present introductory paper offers the elements of a framework in which these consequences, whether privately experienced or publicly observable may be coherently viewed. It is concerned with how to study or understand the factors important in determining how a migrant makes new friends, finds a job, cares for his family, participates in the informational network and takes advantage of the opportunity structure of his new milieu. It is also

Some psychological problems of quadriplegics.

Abstract: Gynrecomastia from \"Aldactone A\" and ethionamide. Dvsuria and urinary retention from anticholinergics (as in the elderly Parkinsonian patient taking \"Lysivane\", \"Cogentin\" and \"Norrtex\", whose dribbling micturrtton was becoming rather more of a problem than his basic disease). Blood dyscrasias of varying types and from many drugs, and compression fractures of vertebrre and aseptic necrosis of the head of the femur with long-term steroid therapy. Prolonged immunosuppressive regtmes (for example, after a renal transplant), during which the patient is being constantly threatened by a host of bizarre \"opportunistic\" organisms, normally not pathogenic to man. The morbidity (and even mortality) associated with some of the newer diagnostic procedures should also be kept in mind, and it is clear that again the possible good must be carefully weighed against the possible harm before such investigations are requested.

Interactive Software Techniques

Abstract: The Graphical Display provides the most flexible and adaptable means of giving information to and receiving information from, a computer It has not yet fulfilled its potential because it is probably the most complicated single peripheral to be attached to a computer
