Abstract
Contemporary critical re-examination of Kahneman's capacity model of attention from his landmark 1973 book. Reviews 45 years of empirical work and argues that attention and effort are not identical constructs. Discusses how the capacity model accounts for individual differences in vigilance, motivational effects on attention allocation, and the relationship between subjective arousal and attentional performance. Notes where the original model holds and where modern neural evidence challenges it. Relevant to understanding individual differences in driver vigilance and fatigue-related attention degradation.
Summary
Conceptual analysis (Frontiers in Psychology 2018) revisiting Kahnemans 1973 Attention and Effort and its claim that attention can be identified with effort. The authors reconstruct the strongest version of the effort-equals-attention thesis (effort as cognitive, objective, metabolic expenditure under sympathetic dominance), then weigh it against subsequent behavioral, physiological, and neuroscience evidence including LC-NE pupillometry and meditation studies. Outlines an alternative paradigm distinguishing readying of resources from utilization of resources.
Key finding
Attention is not identical with effort; attention is better understood as adaptive gain modulation that readies metabolic resources, which can occur under sympathetic dominance (experienced as effortful) or under parasympathetic dominance (experienced as effortless), undermining Kahnemans 1973 equation of attention with effort.
Methodology
Theoretical/conceptual analysis: close re-reading of Kahneman 1973 to extract a falsifiable thesis, evaluated against subsequent empirical evidence on the LC-NE system, pupil dilation, and meditation.
