    Processing capacity impacts choices between simple and complex melodies, independent of arousal levels. Increased arousal, even when relevant, may reduce cognitive processing capacity.

    Area of Science:

    • Cognitive Psychology
    • Auditory Perception
    • Human-Computer Interaction

    Background:

    • Understanding how cognitive load and arousal influence decision-making is crucial.
    • Previous research suggests arousal can impact performance, but its interaction with processing capacity in choice tasks is less clear.

    Purpose of the Study:

    • To investigate the independent and interactive effects of processing capacity and arousal level on choice behavior.
    • To examine how different task demands and auditory stimulation influence melody selection.

    Main Methods:

    • Participants chose between simple and complex computer-generated melodies under divided attention.
    • Auditory stimulation (aversive vs. mild) and varying task demands were manipulated.
    • Measures included choice changes and cardiac arousal.

    Main Results:

    • Processing capacity significantly influenced melody choice, irrespective of arousal fluctuations induced by tasks.
    • Arousal increases from auditory stimulation, even when relevant, appeared to be mediated by reduced processing capacity.

    Conclusions:

    • Cognitive processing capacity is a primary driver of choice complexity, separate from task-induced arousal.
    • Arousal's impact on choice may be indirect, occurring through its effects on cognitive resources.
