| Abstract/Results: | ABSTRACT:
The brain is constantly surveying and selecting relevant visual stimuli to attend to. However, it has been suggested that stimuli with emotional salience (e.g., images of spiders and snakes) can bypass this processing and be processed outside of conscious awareness. To explore this possibility, two experiments were completed in which participants were presented with images of spiders and mushrooms (Experiment 1; N = 35), or snakes and flowers (Experiment 2; N = 35). These images were presented under visible (i.e., the participant was able to perceptually see the images) or invisible (i.e., a visual-masking technique was used to render the images perceptually invisible) conditions. Each experiment had two tasks. In the recognition task, the participant’s Galvanic skin response (GSR) was recorded when viewing visible and invisible stimuli. In the priming task, the participant’s reaction time was measured to a visible target stimulus preceded by either a visible or invisible prime stimulus that was either congruent or incongruent. There were no differences in GSR between conditions in the recognition task for either experiment. In the priming task, there were significant Visibility × Congruency interactions in the spider, F(1,32) = 9.47, p = .004, and snake, F(1,33) = 17.46, p < .001, experiments. Pairwise comparisons, correcting for multiple comparisons using the Bonferroni method, revealed that priming occurred in both visibility conditions with stronger effects for the visible (Experiment 1 Cohen’s d = 1.22; Experiment 2 Cohen’s d = 1.25) compared to invisible (Experiment 1 Cohen’s d = 0.59; Experiment 2 Cohen’s d = 0.53) conditions. Results from the recognition task suggest that there is no difference in the physiological response to the processing of different stimuli. However, in the priming task, results suggest that the invisible stimuli were processed outside of conscious awareness. This suggests that conscious awareness may enhance but is not always required to process certain visual stimuli.
