An Erp Study Of The Effects Of Iconic And Nonsense Gestures On Memory Formation, Brianna E. Cairney
An Erp Study Of The Effects Of Iconic And Nonsense Gestures On Memory Formation, Brianna E. Cairney
LSU Master's Theses
Co-speech gesture is an important part of human communication and aids in comprehension, learning, and memory. The addition of iconic gestures to speech has been shown in prior work to enhance memory for the speech. However, it remains unclear as to whether this benefit requires gestures to be meaningful, or, conversely, if any attentionally-engaging gesture will enhance memory. In the current study, we tested two theories to explain the mnemonic benefits of co-speech gesture: Dual Coding Theory, which attributes these benefits to multimodal encoding and enhanced imageability, and Attentional Highlighting Theory, which posits that gestures draw more attention to concurrent …
Examining Reliability And Validity Of The Roadsign Perception Test, Justin Hull Ory
Examining Reliability And Validity Of The Roadsign Perception Test, Justin Hull Ory
LSU Master's Theses
The Road Sign Perception Test (RSPT) is a newly developed assessment procedure related to driver advisement, and its psychometric properties have not yet been examined systematically. The present study examined the construct validity and the reliability of RSPT measurements. Cronbach’s α and test-retest reliability statistics were completed, as were correlations reflecting on the test’s construct validity. Results indicated that the RSPT possesses marginal test-retest reliability, adequate internal consistency for duration of stimulus presentation and for specific stimuli, but low for number of signs presented. RSPT performance was significantly correlated with convergent variables measuring aspects of attention, working memory, and spatial …
Assessing Attentional Bias And Cerebral Laterality In Specific Phobia Using A Dichotic Listening Paradigm, Whitney Shay Jenkins
Assessing Attentional Bias And Cerebral Laterality In Specific Phobia Using A Dichotic Listening Paradigm, Whitney Shay Jenkins
LSU Master's Theses
Researchers have found fear to impact a variety of cognitive variables in individuals with specific phobia. Attentional bias is a cognitive variable that has received considerable attention in the specific phobia literature; however, the existing literature follows only one line of attentional bias—bias as encoded through images, words, or other content presented visually. This study aimed to expand on this area by assessing attention and cerebral laterality in individuals with specific phobia using a dichotic listening paradigm (i.e., via auditory means). Results indicated that participants with specific phobias do not significantly differ from controls in terms of the number of …
