One study found that familiar stimuli are often preferred to unfamiliar stimuli.

Automatic attentional processes do not require conscious control and are triggered in response to familiar, environmental stimuli.

When information is readily accessible the subject usually makes a contrastive comparison between the new and familiar stimuli.

When the information is moderately accessible they are usually assimilative, not placing either the new or familiar stimuli above the other, but giving them equal status.

Discerning between familiar and unfamiliar stimuli allows for rapid threat appraisals in often hostile environments.

But for some reason, it appears that these loops shut down in the absence of familiar stimuli.

His body merely continued to respond in familiar physical ways to familiar stimuli.

Recognition can also be shown with habituation, the process of attending a familiar stimuli less in preference for a new one.

Normal individuals will look at new stimuli at least two to three times more often than familiar or repetitive stimuli.

Seagrave sat up in the rear seat of Vaughan's car, some familiar stimulus reaching his exhausted brain.
