How Attention And Beat Perception Modulate Neural Entrainment To Rhythm, Aaron Wc Gibbings

Electronic Thesis and Dissertation Repository

Recently, steady-state evoked potentials (SS-EPs) at the frequency of the beat have been observed in electroencephalograms (EEG; Nozaradan et al., 2011, 2012). Previous studies involved participants actively attending to isochronous sequences and repeating rhythms. Here we assessed whether neural enhancement of SS-EPs at beat-related frequencies occurred when (1) participants did not attend to the rhythms, and (2) the rhythm was novel and did not repeat.

When participants listened to rhythms that contained a beat SS-EP enhancement was larger during attended rhythms than when participants were distracted by another task, although SS-EPs were still present in all conditions. SS-EP enhancement therefore …

The Relationship Between Implicit And Explicit Processing In Statistical Language Learning, Nicolette B. Noonan

Electronic Thesis and Dissertation Repository

Statistical language learning is an implicit process wherein language learners track sequential statistics in fluent speech, and may it facilitate the learning of word boundaries. This process is well studied, however, the cognitive mechanisms supporting it remain poorly understood. The present thesis investigated whether domain-specific or cross-domain explicit working memory engagement would impair implicit statistical learning of word boundaries in fluent speech. Participants (n = 110) were exposed to an implicit statistical word segmentation paradigm while concurrently engaged in no other task (control), or an explicit domain- specific (verbal) or cross-domain (visuospatial) working memory task of either low- or high- …

The Effects Of Musical Mood And Musical Arousal On Visual Attention, Angela B. Marti Marca, Tram Nguyen, Jessica Grahn

Undergraduate Honors Theses

The presence of music is a visceral part of the human experience and its influence on cognitive function is a growing area of research in psychology. In particular, perceptual properties of music (mood and arousal) have been shown to significantly affect performance. There has been minimal research in the field on the interaction of mood and arousal and their influence on attention, thus the purpose of this study. Fifty undergraduate students currently enrolled at the University of Western Ontario were recruited for this study. Given that music is a highly subjective experience, participants rated an assortment of music clips on …
