Cardiac perception and cardiac control
Biofeedback and Self-Regulation, 1977The evidence regarding specific cardiac perception and discrimination, and its relationship to voluntary cardiac control, is critically reviewed. Studies are considered in three sections, depending on the method used to assess cardiac perception: questionnaire assessment, discrimination procedures, and heartbeat tracking.

Current Concepts of Children’s Perceptions of Control
The American Journal of Occupational Therapy, 1991Abstract Beliefs about control have been identified as an important aspect of the occupational therapy evaluation process because of their potential influence over the course of action chosen. This paper reviews the current status of research and theory in this area as it relates to children.

Binocular tracking: integrating perception and control
IEEE Transactions on Robotics and Automation, 1999Presents an active binocular tracking system using log-polar images with contributions in both the perceptual and control aspects. The control part is based on the visual servoing framework, including kinematics and dynamics. We introduce a fixation constraint that simplifies the tracking problem by decoupling the visual kinematics and allowing us to ...

Perception of Danger Signals: The Role of Control
Experimental Psychology, 2004Abstract. How does the perceptual system process stimuli that signal aversive outcomes or dangers? Considering the functional links between perception, attention, and action regulation, we posit that when people can avoid the aversive consequences, sensitivity of the perceptual system to danger signals should be enhanced, whereas it should be reduced ...

Participation and Perceptions of Control
Personnel Review, 1976Many managements have responded to the problem of decreasing control in the work situation by implementing participative schemes. Such schemes involve a change from the more traditional confrontation or pure conflict process of bargaining to an approach based on joint problem‐solving and the enhancement of common interest.

Hardware Optimizations for Anytime Perception and Control
2015 IEEE Real-Time Systems Symposium, 2015Autonomous vehicles promise significant benefits to society, from reduced accident rates to greater mobility for the elderly. The biggest challenge in the design of autonomous vehicles comes from the uncertainty of the environment in which they will operate.

From Clarinet Control to Timbre Perception
Acta Acustica united with Acustica, 2010This study investigates the relationships between the control gestures of the clarinet, the generated timbres and their perceptual representation. The understanding of such relationships can provide great interest in several research contexts: synthesis and control (e.g. to improve the quality of current synthesis models), music analysis and perception

Mutuality in the Perception of Affordances and the Control of Movement
2009James Gibson introduced the concept of affordance to emphasize the importance of behavior in constraining perception. In this view, perception is not judged in terms of sensitivities to properties that are measured by physical instruments (photometers for brightness, scales for weight, etc.) but in terms of properties that matter to behaving systems ...

Perceptions and control of assemblage in a ‘Glocal’ World
Dialogues in Human Geography, 2017Assemblage theory has pushed us in the right direction but it should ontologically better articulate the question of actor’s perception of environment and power in a global-local (‘glocal’) context of a capitalist and monetized world. This commentary attempts to articulate how to marry assemblage theory with new concepts arising from a combination of ...

Children's perceptions of who controls their food
Journal of Human Nutrition and Dietetics, 2000Background The purpose of this study was to explore children's perceptions of who controlled the quality and quantity of their food during the week.Methods Semi structured interviews were carried out with 98 9‐year‐old children. The children were asked to describe who chose what they ate during a typical week day. They were also asked about who decided
