An exploratory study of the effect of high and low fascination environments on attentional fatigue

According to attention restoration theory attentional fatigue can be renewed in environments where fascinating stimuli are present as they evoke effortless attention and allow directed attention to rest and be restored. The present study hypothesizes that performing an attention-orienting task in a state of attentional fatigue costs less in a high fascination than in a low fascination condition. In the former attentional shifts are expected to be facilitated because one can function in the involuntary mode. The high fascination condition is also expected to facilitate attention in the coding process and therefore to affect the likelihood of stimulus material to be remembered. To this end 31 subjects were mentally fatigued by performing a sustained attention test. Then they performed an ad hoc attention-orienting task inspired by Posner's paradigm and applied to 40 photographs of environments already assessed for their fascination value. Finally they performed an incidental memory task. As expected, only in the high fascination condition did participants show a significant benefit (reaction time reduction) in shifting attention between trials. The role of fascination on recall is less clear since it interacts with the naturalness of the scene.
