Temperament And Individual Differences In Category Learning, Tianshu Zhu

Electronic Thesis and Dissertation Repository

Objectives. Individuals can differ in their strategic approach in learning the same categorization task, researchers have sought to study what specific stable individual differences traits can help explain these differences. This dissertation first surveyed extant literature on the impact of trait differences on category learning then examined the effect of temperament traits on these dependent variables. Chapter 2 (scoping review): This scoping review synthesized the past literature that examined the relationship between sources of stable individual differences and category learning performance and strategy use outcomes. Five database platforms were searched to identify relevant articles, cross-referencing was also performed. Sixty-nine studies …

Characterizing The Familiar-Voice Benefit To Intelligibility, Beatriz Ysabel Domingo

Electronic Thesis and Dissertation Repository

Everyday listening often occurs in the presence of background noise. Listeners with normal hearing can often successfully segregate competing sounds from the signal of interest. To do this, listeners exploit a variety of cues to facilitate the separation of simultaneous sounds into separate sources, and group sequential sounds into intelligible speech streams. One of the cues that has been shown to be an effective facilitator of speech intelligibility is familiarity with a talker’s voice. A recent study by Johnsrude et al. (2013) measured speech intelligibility of a naturally familiar voice (i.e., that of a long-term spouse) and showed a …

Dual Route Model Of Idiom Processing In The Bilingual Context, Tianshu Zhu

Electronic Thesis and Dissertation Repository

The dual route model predicts that idiomatic phrases show a processing advantage over matched novel phrases. This model postulates that familiar phrases are processed by a faster direct route, and novel phrases are processed by an indirect route. This thesis investigated the role of familiar form and concept in direct route activation. Study 1 provided norming evidence for experimental stimuli selection. Study 2 examined whether direct route can be activated for translated Chinese idioms in Chinese-English bilinguals. Bilinguals listened to the idiom up until the last word (e.g., draw a snake and add), then saw either the idiom ending (e.g., …

Assessing The Impact Of Emotion In Dual Pathway Models Of Sensory Processing., James H. Kryklywy

Electronic Thesis and Dissertation Repository

In our daily environment, we are constantly encountering an endless stream of information which we must be able to sort and prioritize. Some of the features that influence this are the emotional nature of stimuli and the emotional context of events. Emotional information is often given preferential access to neurocognitive resources, including within sensory processing systems. Interestingly, both auditory and visual systems are divided into dual processing streams; a ventral object identity/perception stream and a dorsal object location/action stream. While effects of emotion on the ventral streams are relatively well defined, its effect on dorsal stream processes remains unclear.

Exploring And Training Spatial Reasoning Via Eye Movements: Implications On Performance, Victoria A. Roach

Electronic Thesis and Dissertation Repository

This dissertation sought to determine if eye movements could serve as an indicator of success in spatial reasoning, and if eye movements associated with successful completion could be applied to strategically improve spatial reasoning.

Using the line images of Shepard and Metzler, an electronic test of mental rotations ability (EMRT) was designed. Two versions of the test were created, allowing for both a timed (6 seconds per question) and untimed testing environment. Four experiments were designed and completed to relate mental rotation ability (MRA) scores from the EMRT, to patterns in chrononumeric and visual salience data. In each experiment, participants …

A Kinematic Analysis Of Visual And Haptic Contributions To Precision Grasping In A Patient With Visual Form Agnosia And In Normally-Sighted Populations, Robert Whitwell

Electronic Thesis and Dissertation Repository

Skilled arm and hand movments designed to obtain and manipulate objects (prehension) is one of the defining features of primates. According to the two visual system hypothesis (TVSH) vision can be parsed into two systems: (1) the ventral ‘stream’ of the occipital and inferotemporal cortex which services visual perception and other cognitive functions and (2) the ‘dorsal stream’ of the occipital and posterior parietal cortex which services skilled, goal-directed actions such as prehension. A cornerstone of the TVSH is the ‘perception-action’ dissociation observed in patient DF who suffers from visual form agnosia following bilateral damage to her ventral stream. DF …

Music And Auditory Transportation: An Investigation Of The Music Experience, Gail Leizerovici

Electronic Thesis and Dissertation Repository

To date, music has been primarily investigated as an atmospheric component of retail environments, or as a manipulable variable to assess consumer behaviour responses. However, across disciplines, listening to music has been shown to foster group membership, decrease anxiety, improve mood, and induce strong physical reactions such as thrills and chills. My dissertation research looks at closing this gap by investigating how music can offer more to its consumer than is currently understood. Using a mixed-method approach, I first explore the phenomenon of experiencing a favourite song. Following that, I experimentally investigate: 1) how and whether different modes of music …
