Abstract:
Vision and action systems have a high level of integration as demonstrated by both experimental and neuropsychological evidence. Fluency of perceptual processing has been shown to influence affective reactions to stimuli, such that fluent visual processing leads to positive affect. This thesis investigates whether tasks that combine vision and action can produce a sensorimotor fluency based affective response. Explicit measures using liking scales and forced choice preference tasks found mixed results, with some experiments showing sensorimotor fluency based explicit affect (Experiments 2.2 and 2.3), while others produced null effects (Experiments 4.1 and 4.2). To investigate this ambiguity, a direct measure of affect was implemented by measuring affective facial expressions using electromyography (EMG). This technique had not previously been used while participants performed speeded responses as part of a task. This EMG measure was demonstrated to be effective as a measure of affective facial expressions (Experiments 3.1 and 3.2) and was therefore suitable for the present sensorimotor fluency investigation. This direct measure revealed that, similar to perceptual fluency findings, there was greater muscle activation of the zygomaticus muscle associated with smiling when responding to objects that were presented in a sensorimotor fluent condition compared to objects that were presented in a sensorimotor incompatible non-fluent condition (Experiment 4.2). These experiments confirm that sensorimotor fluency does indeed influence affect, and that high fluency is directly experienced as positive affect.
