Abstract/Description
The observation of contrast effects (CE) in response to differential relnforcenent has subsequently elicited a diversity of experimental results and theoretical interpretations. Adaptation Level (AL ) concepts have provided a mechanism for integrating such data within a psychophysical frame-of-reference approach. The application of this approach to the somewhat neglected area of response-produced stimuli associated with effort, suggests that proprioceptive stimuli may be effectively evaluated...
Show moreThe observation of contrast effects (CE) in response to differential relnforcenent has subsequently elicited a diversity of experimental results and theoretical interpretations. Adaptation Level (AL ) concepts have provided a mechanism for integrating such data within a psychophysical frame-of-reference approach. The application of this approach to the somewhat neglected area of response-produced stimuli associated with effort, suggests that proprioceptive stimuli may be effectively evaluated in a simllar manner. Following shifts in the amount of effort required to produce a constant reward magnitude, performance measures demonstrated positive and negative contrast effects (PCE; NCE) in relation to an appropriate control performance. Data analysis suggested that the combined effects of greater effort and shift conditions tended to increase resistance to extinction. The findings are not consistent Kith traditional (e. g., Hull, Spence) concepts with regard to CE and the influence of effort on performance. It is suggested that such effects are more consistent with a contextual, or frame-of- reference, viewpoint.
