The Neuropsychological Deficits In Cannabis Users : Does Motivation Play A Role?, Rayna Beth Ericson Jan 2010

The Neuropsychological Deficits In Cannabis Users : Does Motivation Play A Role?, Rayna Beth Ericson

Legacy Theses & Dissertations (2009 - 2024)

Prior research of the neuropsychological functioning of cannabis users has yielded mixed results, in that some studies identified differences compared to non-users, while others found no group differences at all. A meta-analysis revealed a small effect of cannabis use on the cognitive domains of learning and forgetting, while domains such as attention and processing speed yielded no effect (Grant et al., 2003). However, none of the previous studies assessed the participants' motivation to perform well on the assessment, which may have influenced the results. The present study sought to determine whether motivation is differentially demonstrated in cannabis users compared to …


Word Concreteness And Word Frequency As Moderators Of The Tip-Of-The-Tongue Effect, Jennifer Lynn Gianico Jan 2010

Word Concreteness And Word Frequency As Moderators Of The Tip-Of-The-Tongue Effect, Jennifer Lynn Gianico

Legacy Theses & Dissertations (2009 - 2024)

The tip-of-the-tongue (TOT) experience is a universal experience in which a speaker cannot fully produce a word that he or she believes will eventually be recalled and could easily be recognized. The purpose of the current set of experiments is to determine how different variables affect the rate of TOTs. Specifically, a series of three experiments investigates the roles of word concreteness and word frequency on TOT rates. A new finding, the concreteness effect on TOT rates, emerged and was replicated across all three experiments. This never-before investigated concreteness effect is discussed in terms of a general two-stage model of …

Resolving Incomparability, David Pinkowski

Legacy Theses & Dissertations (2009 - 2024)

When confronted with an important choice between two very different options, an agent often will be at a loss as to how to decide between them. This is often true even if the agent has a good understanding of the pros and cons of each option, and even if she is committed to something like "the best overall decision for me." One way to analyze this situation is to assert that the options are incomparable for the agent. Incomparability arises when, for two options, it seems that one is neither better nor worse than, nor equal to, the other. If …


The Influence Of Emotion On Attention : Examining The Processing Of Negative And Positive Emotion Words In The Dot Probe Task, Tina Sutton Jan 2010

The Influence Of Emotion On Attention : Examining The Processing Of Negative And Positive Emotion Words In The Dot Probe Task, Tina Sutton

Legacy Theses & Dissertations (2009 - 2024)

The influence of emotion on attention has been examined more closely in recent years using a variety of paradigms. Öhman (1993) suggested that participants more readily pay attention to negative information than neutral information. The current work was designed to expand upon these findings by examining both negative and positive emotion word processing in a non-clinical population using the dot probe task. Experiments 1a and 1b examined the supraliminal and subliminal processing of negative and positive emotion words presented in separate blocks. The results revealed that participants responded faster to the probe when it appeared in the same location as …
