(2004) and confirmed that increasing memory load disrupted performance in the classic flanker task. Experiment 2 used the same manipulation of WM load to probe attention during the viewing of complex scenes, while also investigating individual differences in ADHD traits. In the image viewing task, we measured the degree to which fixations targeted each of two crucial objects: (1) a social object (a person in the scene) and (2) a non-social object of higher or lower physical salience. We compared the extent to which increasing WM load would change the pattern of viewing of the physically salient and socially salient objects. If attending to the social item requires greater default voluntary top-down resources, then the viewing of social objects should show stronger modulation by WM load compared to viewing of physically salient objects. The results showed that the social object was fixated to a greater degree than the other object (regardless of physical saliency). Increased saliency drew fixations away from the background leading to slightly increased fixations on the non-social object, without changing fixations on the social object. Increased levels of ADHD-like traits were associated with fewer fixations on the social object, but only in the high salient, low load condition. Importantly, WM load did not affect number of fixations on the social object. Such findings suggest rather surprisingly that attending to a social area in complex stimuli is not dependent on the availability of voluntary top-down processes

Get PDFThe current thesis examines the effects of cognitive load, social object, non-social object and ADHD-like traits on visual attention. This thesis reports (Experiment 1 and 2) a modified version of Lavie et al, (2004; 2005) and confirmed that increased memory load disrupted performance in the classic flanker task, but not in the singleton. Experiment 3 uses the same manipulation of WM load to probe attention during the viewing of complex scenes. Experiment 4 and 5 examine the effects of visuospatial WM on different presentations: sequential and simultaneous. These experiments compare the extent to which increasing WM load would change the pattern of viewing of the physically salient and socially salient objects while also investigating differences in ADHD traits. Experiment 6 examines the effects of instructions on the image-viewing task by restricting areas such as: social and non-social. Experiments 7 and 8 examine the effects of occluding the eyes in a conversation in traits of ADHD and ASD (low vs high). Experiments 9 examines the relationship between working memory components (maintenance and distractor processing) and ADHD traits within the general population. This thesis discusses their results based on visual prioritisations (social, high and low salience), cognitive load and the heterogeneity of ADHD and their comorbidities. Taken together these results provide interesting implications in eye movements behaviour, in the understanding of individual differences and in the underlying cognitive abilities
