The Structure Of Working Memory: A Review And New View Of Psychometric Models, Kevin Pablo Rosales
The Structure Of Working Memory: A Review And New View Of Psychometric Models, Kevin Pablo Rosales
CGU Theses & Dissertations
Beginning in the 1970s, a great deal of research in cognitive psychology, developmental psychology, psychometrics, and cognitive neuroscience has investigated the structure and function of working memory (WM), defined as the ability to actively maintain and manipulate information in the service of complex cognition (Baddeley & Hitch, 1974). It is well established that WM is a limited capacity system and individual differences in WM capacity are strongly associated with important cognitive abilities and outcomes, such as general intelligence (Engle et al., 1999) and academic achievement (Swanson & Berninger, 1996; Ramirez et al., 2013). For this reason, WM is a central …
Consonant And Dissonant Music Chords Improve Visual Attention Capture, Graham Spurrier
Consonant And Dissonant Music Chords Improve Visual Attention Capture, Graham Spurrier
CMC Senior Theses
Recent research has suggested that music may enhance or reduce cognitive interference, depending on whether it is tonally consonant or dissonant. Tonal consonance is often described as being pleasant and agreeable, while tonal dissonance is often described as being unpleasant and harsh. However, the exact cognitive mechanisms underlying these effects remain unclear. We hypothesize that tonal dissonance may increase cognitive interference through its effects on attentional cueing. We predict that (a) consonant musical chords are attentionally demanding, but (b) dissonant musical chords are more attentionally demanding than consonant musical chords. Using a Posner cueing task, a standard measure of attention …
Are You Feeling Me?: The Role Of Attention In Physiological Empathetic Responses, Gabriela Paganini
Are You Feeling Me?: The Role Of Attention In Physiological Empathetic Responses, Gabriela Paganini
Scripps Senior Theses
This study examined the role of attention and trait empathy within the production of neural facial mimicry responses that have been previously found to be associated with the experience of empathy. More specifically, do people who have high trait empathy levels require less attention to emotional information in order to still exhibit these physiological responses than people who have lower trait empathy levels? It has previously been demonstrated that responses in the zygomaticus and corrugator muscles have been associated with the experience of empathy. College aged participants were shown series of happy, angry, and neutral faces with the amount of …

Attention's Grasp: Early And Late Hand Proximity Effects On Visual Evoked Potentials, Catherine L. Reed, David S. Leland, Benjamin Brekke '11, Alan Hartley

Behavioral studies suggest that visual attention is biased toward stimuli in the region of space near the palm of the hand, but it is unclear whether this effect is universal or selective for goal/task-related stimuli. We examined event-related potentials (ERPs) using a visual detection task in which the hand was placed near or kept far from target and non-target stimuli that were matched for frequency and visual features to avoid confounding factors. Focusing on attention-sensitive ERP components, we found that P3 (350–450 ms) amplitudes were increased for Hand Near conditions for targets only, demonstrating a selective effect consistent with the …
