Appendix A Time course of visual Attention (Doctoral Dissertation Abstract) When a given object is identified, it impairs the identification of a subsequent target for approximately half a second. The current thesis investigates the time course of covert shifts of visual attention modulated by different attentional sets/modes, by manipulating object-based properties such as emotion and perceptual levels. Two studies were conducted employing the attentional dwell time paradigm, in which two targets were presented at two different locations with a variable temporal separation between the targets. Participants showed less cost in shifting attention from one object to another when they attended to happy faces (either as T1 or T2) compared to sad faces. Also, an attenuated cost in shifting attention was obtained during shift from global to global perceptual levels, compared to local to local or global to local or local to global perceptual levels. Moreover, the shifts of visual attention was slower across objects attended at different perceptual levels compared to the objects attended at same perceptual level and took approximately a second, longer time than the switch between same attentional mode. The result extends the previous findings linking happy/global information with distributed attention and sad/local information with focused attention by showing better shifts of visual attention when they attended to happy/global target compared to when they attended to sad/local target. The findings indicate that less attentional resource is required during distributed attention and it facilitates shift of attention across objects over time demonstrating benefits of distributed attention over focused attention. Moreover, the findings indicate that additional attentional resources are required for reconfiguration of attentional system for shifting between objects attended at different perceptual levels. The results clearly indicate that the time course of visual attention depends on the mode/set of attention and object-based properties.

Appendix B Object-based Attention (Master’s Thesis Abstract) Studies on visual attention show that it can be deployed to both location and features of objects. Attention shifts from one location or object to another location or object respectively. With locations, facilitation at early cue-to-target intervals is followed by inhibition at longer cue-to-target intervals (>350 ms). We explored the effect of attention as a function of cue-to-target intervals for object-based attention. We used the paradigm first used by Egly and colleagues which can be used to explore both location-based and object-based attention. The experiment was performed with three cue-to-target intervals (200,500,800 ms). The stimuli used were rectangular bars presented one either side of the fixation. The cue was a brightening of the end portion of one of the rectangular bars and the target was a small square portion on the inside end of the rectangular bar. The target to be detected appeared in one of the three possible locations for a given cue and resulted in the following cue-target conditions: valid, invalid within-target and invalid between-target. Results showed that reaction times (RTs) were generally faster for valid trials than invalid trials. While the cuing effect decreased with longer cue-to-target intervals, no inhibition of return was found with this paradigm. The result also showed that the cuing effect was different for the within-object condition compared to between-object condition. In addition, the effects were also different for different visual fields indicating the presence of laterality effects in this paradigm. Further studies are needed to explore the timecourse of object-based attention especially inhibition of return in object-based attention.
