Investigating The Proposed Mechanisms Guiding Negative Attentional Templates, Michael Kevin Mugno

Masters Theses

To complete goal-directed visual search, information that is gathered in working memory must be sorted by relevancy to the current task. In order to bias search, attentional templates are created within the construct of visual working memory (VWM) using both endogenous and exogenous information. While most attentional templates are built around positive information, which is directly relevant to the target of search, there are cases where negative information, which is directly relevant to the search but not necessarily the target itself, may be more efficient. However, the mechanisms behind how these negative templates direct search is debated. The goal of …

Rethinking Attention Control: An Individual Differences Approach, Vincent A. Medina

LSU Doctoral Dissertations

While there is extensive literature on visual spatial attention, less is known about auditory spatial attention, especially in terms of attention control. There is also a growing literature highlighting the importance of considering individual differences in attention control ability. Given these points, the purpose of this study was twofold. The first was to understand how auditory attention control is influenced by spatial location as well as vision. The second was to examine whether individual differences in attention control ability can predict task performance in that context. We utilized two tasks for these purposes. Experiment 1a consisted of a cross-modal Stroop …

The Long-Term Effects Of Cannabis On Attention To Motion, Rachel Mccaig

Theses and Dissertations (Comprehensive)

The purpose of the following study was to investigate the long-term effects of cannabis use on attention to motion.

Methods: Cannabis users, who varied in age of onset of use, were compared to control participants after abstaining from cannabis for at least 24 hours. One-hundred and ninety-seven participants engaged in a cognitive assessment followed by a motion discrimination task and an attention to motion task. The assessment consisted of a series of standard tasks that measured a range of cognitive processes such as attention, memory, and executive functioning. The motion discrimination task assessed the participants’ abilities in discriminating between various …
