Forster and Lavie (2008) and Lavie, Lin, Zokaei and Thoma (2009) have demonstrated that meaningful stimuli, such as objects, are ignored under conditions of high perceptual load but not low. However, objects are seldom presented without context in the real world. Given that context can reduce the threshold for object recognition (Barenholtz, 2013), is it possible for context to reduce the processing load of objects such that they can be processed under high load? In the first experiment, I attempted to obtain similar findings of the aforementioned studies by replicating their paradigm with photographs of real-world objects. The findings of the experiment suggested that objects can cause distractor interference under high load conditions, but not low load conditions. These findings are opposite of what the perceptual literature suggests (e.g., Lavie, 1995). However, these findings are aligned with a two-stage dilution model of attention in which information is first processed in parallel and then selectively (Wilson, Muroi, and MacLeod, 2011). Experiment 2 assessed if this effect was specific to semantic objects by introducing meaningless, abstract objects. The results suggest that the dilution effect was not due to the semantic features of objects. The third experiment assessed the influence of context on objects under load. The results of the experiment found an elimination of all interference effects in both the high and low load conditions. Comparisons between scene-object congruency revealed no influence of semantic information from scenes. It appears that the presentation of a visual stimuli prior to the flanker task diluted attention such that the distractor effects previously observed in the high load condition were minimized. Thus, it does not appear that context reduced the threshold for object recognition under load. All three experiments have demonstrated strong evidence for the dilution approach of attention over perceptual load models. / Includes bibliography. / Dissertation (Ph.D.)--Florida Atlantic University, 2019. / FAU Electronic Theses and Dissertations Collection
