Does Preference for Abstract Patterns Relate to Information Processing and Perceived Duration?

ABSTRACT

Repetitive prestimulation, in the form of click trains, is known to alter a wide range of cognitive and perceptual judgments. To date, no research has explored whether click trains also influence subjective preferences. This is plausible because preference is related to perceptual fluency and clicks may increase fluency, or, because preference is related to arousal and clicks may increase arousal. In Experiment 1, participants heard a click train, white noise, or silence through headphones and then saw an abstract symmetrical pattern on the screen for 0.5, 1, or 1.5 s. They rated the pattern on a 7-point scale. Click trains had no effect on preference ratings, although patterns that lasted longer were preferred. In Experiment 2, we again presented a click train, silence, or white noise but included both symmetrical and random patterns. Participants made both a duration and a preference judgment on every trial. Auditory click trains increased perceived duration, and symmetrical patterns were perceived as lasting longer than random patterns. Again there was no effect of auditory click trains on preference, and again patterns that were presented for longer were preferred. We conclude that click trains alter perceptual and cognitive processes, but not preferences. This helps clarify the nature of the click train effect and shows which predictions implicit in the existing literature are supported.

Experiment 2 method. (a) Illustration of type of stimuli (symmetrical vs. random). (b) Each trial started with a fixation cross, while an auditory stimulation (clicks or white noise or silence) was presented for 4 s. A symmetrical or random pattern was presented for one of five possible durations in seconds (0.5, 0.75, 1.0, 1.25, 1.50). On every trial, participants rated preference for the pattern and estimated pattern durations.

On every trial, participants rated preference for the pattern and estimated pattern durations.

Mentions: On the basis of the results of Experiment 1, we did not expect clicks to have any effect on preference in the symmetrical condition. There may, however, be an effect of click trains in the random condition. On the basis of extensive previous literature, we did expect click trains to increase perceived duration. This would suggest that the effect in Experiment 1 could not be attributed to the unusual absence of an influence of click trains on perceptual processes. Complexity was not manipulated in Experiment 2. Every pattern was a 10 × 10 black and white matrix (Figure 3). Our previous work shows that this kind of image complexity has no effect on subjective duration (Palumbo, Ogden, Makin, & Bertamini, 2014).Figure 3.
