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 …

Mental Imagery In Fear Extinction: A Multi-Component Examination Based On Behavioral, Physiological, And Neurological Measures, Xinrui Jiang
LSU Doctoral Dissertations
Imagery has long been utilized in clinical treatments of affective symptoms with the assumption that mental imagery can stand in for its perceptual counterpart and exert regulatory effects over emotional responses. While this assumption has its ground in theoretical framework of mental imagery supported by evidence of neurological overlaps between imagery and perception, and clinical applications of imagery interventions were found to be successful, very little has been done through means of experimental examinations.
This investigation began with a differential fear conditioning study (study 1) to simulate and assess imagery extinction. Results provided support for the efficacy of imagery exposure …
