Mapping Reward Values To Cues, Locations, And Objects: The Influence Of Reward Associations On Visual Attention, Constanza De Dios
Mapping Reward Values To Cues, Locations, And Objects: The Influence Of Reward Associations On Visual Attention, Constanza De Dios
USF Tampa Graduate Theses and Dissertations
Previous work has attempted to fit reward-driven attentional selection as being exogenous (stimulus-driven) or endogenous (goal-driven). However, recent work suggests that reward’s effects on attention depend on the type of stimulus feature that the motivational information is imparted during learning (incentive salience). If true, then reward should not be limited to solely impacting early perceptual or late categorization processes attention. The current study used event-related potentials (ERPs) to test the idea that reward’s effects on attention depend on the process that the reward information is embedded – early perceptual or late categorization. Results demonstrated reward-driven effects on perceptual representation when …
Visual Search For Smoking Stimuli: Detection And Distraction, Jason A. Oliver
Visual Search For Smoking Stimuli: Detection And Distraction, Jason A. Oliver
USF Tampa Graduate Theses and Dissertations
Extensive research has shown that the attentional systems of addicted individuals are biased towards drug-related stimuli, but despite several decades of effort these results have frequently been inconsistent. Though commonly believed to result from addiction and dependence, cognitive research would suggest that frequent exposure to drug-related stimuli could affect the attentional processing of drug-related cues even if no actual drug use occurs. The present investigation examined attentional bias for smoking cues using a novel visual search paradigm amongst smokers currently in nicotine withdrawal and fully satiated smokers, as well as a non-smoker control group. Variables related to smoking behavior, as …
The Role Of Contextual Associations In The Selection Of Objects, Noah Patrick Sulman
The Role Of Contextual Associations In The Selection Of Objects, Noah Patrick Sulman
USF Tampa Graduate Theses and Dissertations
This paper describes a sequence of experiments addressing basic questions about the control of visual attention and the relationship between attention and object recognition. This work reviews compelling findings addressing attentional control on the basis of high-level perceptual properties. In five experiments observers were presented with a rapid sequence of object photographs and instructed to either detect or selectively encode a verbally cued object category. When these object categories (e.g. "baseball") were preceded by contextual images associated with a given object category (e.g. "baseball diamond"), observers were less likely to accurately report information about the target item. This effect obtained …
