An Investigation Of The Increased Reliance On Familiarity In Associative Recognition Of Unitized Compound Word Pairs, Fahad Naveed Ahmad Jan 2015

An Investigation Of The Increased Reliance On Familiarity In Associative Recognition Of Unitized Compound Word Pairs, Fahad Naveed Ahmad

Theses and Dissertations (Comprehensive)

Unitization refers to when two components are integrated or combined into a single unit. So the whole is more familiar than the parts (Graf & Schacter, 1989). Previous researchers have shown unitization of unrelated word pairs can occur by the use of compound definition. As support, they have found unitization to increase reliance on familiarity in associative recognition. The purpose of this PhD dissertation was to examine the effects of unitization of preexperimental associations on associative recognition. The effects of associative recognition of unitized compound word (CW) pairs can serve as a useful benchmark to compare to that of other …


Connecting To Others: Studying The Relationship Between Social Exclusion And Imitation, Sarah K. Blyth Jan 2015

Connecting To Others: Studying The Relationship Between Social Exclusion And Imitation, Sarah K. Blyth

Theses and Dissertations (Comprehensive)

Automatic imitation (AI) refers to the subconscious tendency we have to imitate an observed action, even when that action is irrelevant to or interferes with an action we are attempting to execute (Heyes, 2011; Brass et al., 2000). Human beings display a fundamental need to stay meaningfully connected to others, also known as the need to belong. Previous research shows that an experience of rejection can reduce one’s feelings of connectedness to others (Legate et al., 2013), and that behaviours such as non-conscious mimicry (NCM) increase after being excluded as a possible means of re-affiliation (Lakin et al., 2008). It …


Imagining Accomplishments From Differing Visual And Temporal Perspectives, Deanna C. Hall Jan 2015

Imagining Accomplishments From Differing Visual And Temporal Perspectives, Deanna C. Hall

Theses and Dissertations (Comprehensive)

The current research examined the relationship between grammatical aspect (GA) (imperfective vs. past perfect) and accomplishment verbs in event representation in Experiment 1, and then investigated the influence of visual perspective taking on this representation process in Experiment 2. Electroencephalography (EEG) was recorded with slow cortical potentials (SCPs) acting as a measure of cognitive processing during the imagination period, and behavioural measure questionnaires provided ratings of vividness, temporal component, and importance of the imagined events.

It was hypothesized for Experiment 1 that imagining imperfective events would result in more negative SCP amplitudes than when imagining events with past perfect aspect, …


Influence Of Planning Resources On Gait Control In Parkinson’S Disease, Frederico P. Faria Jan 2015

Influence Of Planning Resources On Gait Control In Parkinson’S Disease, Frederico P. Faria

Theses and Dissertations (Comprehensive)

Movement disturbances in individuals with Parkinson’s disease (PD) have been associated with difficulties to plan complex actions. Performance of simple and complex actions overloads resources for individuals with Parkinson’s disease (PD). However, it is unclear if central resources required to plan gait adjustments while walking exacerbate gait disturbances of patients with PD. More specifically, it is unclear how gait impairments, sensory processing, and the dopaminergic system influence the load on processing resources (e.g. cognitive load) during the planning of step modifications. In order to investigate the relative influence of these factors on cognitive load and its impact on gait control, …


The Effect Of Emotion On Associative And Item Memory, Priyanga Jeyarathnarajah Jan 2015

The Effect Of Emotion On Associative And Item Memory, Priyanga Jeyarathnarajah

Theses and Dissertations (Comprehensive)

Numerous studies to date have demonstrated superior memory for emotional compared to neutral stimuli (Kensinger & Corkin, 2004; Bennion et al., 2013). This finding, although relatively stable across the item memory literature, becomes less consistent when examined in tasks measuring memory for associative or source information (Chiu et al., 2013). For this reason, the present study set out to examine how emotional content (negative, positive and neutral word pairs) influences memory in two distinct associative and item recognition tasks: associative identification (AI), associative reinstatement (AR), paired-item recognition, and single-item recognition. In measuring the influence of emotion on associations using an …
