[Visual Priming and Perception of the Small Pictures in Scene with Multiscale Objects.]

Area of Science:

• Visual perception
• Cognitive psychology
• Psychophysics

Background:

• Previous research indicated priming effects are independent of angular size differences.
• However, these studies examined a limited range of stimulus sizes.
• Perception differs for stimuli above and below 1-1.5 degrees angular size.

Purpose of the Study:

• Investigate priming effects with large angular size differences (4 deg vs. 0.5 deg).
• Examine priming in a match-to-sample task across different size ranges.
• Assess the impact of noise on priming with varying stimulus sizes.

Main Methods:

• Match-to-sample task with stimuli of 4 degrees and 0.5 degrees angular size.
• Stimuli presented with and without noise superposition.
• Analysis of priming effect suppression and enhancement.

Main Results:

• Priming effect is suppressed when there is a large difference in angular size between primer and test stimuli.
• A congruent primer can positively influence test object recognition.
• This positive impact occurs specifically under noisy viewing conditions.

Conclusions:

• Visual perception priming is sensitive to the angular size difference between stimuli.
• Large size disparities disrupt the priming effect.
• Noise can modulate priming, potentially aiding recognition under challenging conditions.
