Direct Perception-Action Coupling: A Neo-Gibsonian Model for Critical Human-Machine Interactions under Stress

Abstract

The cognitive capacities of a human agent are significantly impoverished when operating under severe temporal and emotional stress. Currently, human-machine interaction under these circumstances is being informed by classical cognitive models, which treat the human agent as having a repertoire of undiminished cognitive capacities consisting of semantic, symbolic, and inferential reasoning abilities. Such an approach is unsuited when an agent’s mental capacities are reduced to simple perception-action mechanisms, due to functional decortication, under severe stress. Gibson’s direct perception provides a partial answer to this problem. This paper attempts to provide a more robust answer by putting direct perception under the light of recent advances made in human-machine interaction design and theory, neurosciences and embodied cognition. This resulted in the development of a model for human-machine interaction called Direct Perception-Action Coupling (DPAC). This model can be applied to inform the design of critical human-machine interactions that need to be flawlessly performed, often times under stress, to prevent catastrophic outcomes.

Expectancy or Salience?—Replicating Senders’ Dial-Monitoring Experiments With a Gaze-Contingent Window

“…These findings provide empirical support for display design recommendations previously formulated by Wickens and McCarley (2008) : “ we prescribe that display designers should (a) correlate salience with value so that important events will be likely to capture attention; and (b) correlate distance, or effort, between two AOIs inversely with their joint expectancy so that sources of high bandwidth are close together, requiring minimal attention travel ” (p. 58). Thus, it may be argued that critical events should be sufficiently salient and that any interface should be designed so that even without any experience, people can understand it ( Rahman, 2012 ). Applying these principles to an automated driving system, a head-up display could be used to highlight potential hazards and system limits, making it clear when and how the driver should regain control.…”

It’s not what, but where: how the accentuated features of the adventure sports coaching environment promote the development of sophisticated epistemic beliefs

“…Gibson (1979) saw perception and action as directly coupled where the perceptual system is constantly acquiring information about opportunities for action. These opportunities are known as affordances (Rahman, 2012). 'Seeing' an affordance is a transactional process; affordances emerge as a function of the state of the environment and capabilities of the observer (Fajen, Riley & Turvey, 2008;Orth, Davids, Chow, Brymer & Seifert, 2018).…”

Etologia, cognição e sistemas em desenvolvimento

“…Das conexões neuronais, formadas por componentes simples, emergiriam estados globais. A ideia de representação foi mantida, mas foi reformulada: não se trata apenas de representar símbolos, pois passa a haver espaço para interações mais complexas entre os elementos constitutivos das redes, e entende-se que sua distribuição e as suas conectividades são moldadas pelo que é vivenciado no mundo real (Rahman, 2012). No caso do conexionismo, há uma aproximação entre a cognição e o corpo, ainda que o cérebro continue sendo o centro da cognição, e que o resto do corpo cumpra uma função menor ligada à percepção (input) e à ação (output).…”
