Task Switching and Distractibility
In this thesis I examined the effects of task switching on people’s ability to ignore irrelevant distractors. Load theory proposes that distractor interference critically depends on the availability of executive control to minimise the effects of irrelevant stimuli (e.g. Lavie, 2000). Much work on …

Task switching and short-term retention: The role of memory load in task switching performance
Shifting, which is the process of switching task sets between two or more tasks, incurs a cost: participants are slower and more error prone when a switch is required, relative to when the same task is performed in a sequential manner. Recent research in our lab has found a performance dissociation …

Life -Span Changes in Task Switching
… age-related changes during performance of some tasks. Two experiments presented here examine whether a specific task switching ability develops and declines at a different rate than general changes in processing speed and working memory capacity. Results suggest that processing speed alone, …

Task Switching in Predictable and Unpredictable Cases
… the cognitive processes that underlie the switching between simple cognitive tasks. Central to these experiments was the predictability factor; in half of the cases, the upcoming task could be predicted in advance with absolute certainty while in the other half no foreknowledge regarding …

Characterizing Task-Switching Performance in Adults with ADHD
… many areas of executive functioning, including task-switching. Individuals with ADHD are typically slower and less accurate when switching between tasks during a cued paradigm. However, Sams et al. (2017) examined task-switching ability in adult ADHD with a more naturalistic voluntary paradigm …

The neurophysiology of intersensory selective attention and task switching
… piece of the environment to another and from one task to another. This process is generally referred to as task-switching.</p> <p>Neural oscillations in the alpha band (~8-14 Hz) have been shown to index the distribution of selective attention, and there is increasing evidence that oscillations in …

Gender Differences in Task Switching: An Event-Related Potential Study
… times between males and females in relation to task switching. Previous research has shown gender differences in various aspects of cognition including task switching. Task switching refers to the ability to cognitively switch from processing one task to processing another, completely different …

Inhibitory control mechanisms and their role in task switching: A multi-methodological approach
… us to ignore distraction and switch between tasks in a flexible, yet organized fashion. While a hallmark of controlled behavior, distinctions among executive control processes are not thoroughly agreed upon. The present work explored the organization of two of these executive control …

The relationship between working memory and cognitive control : the role of task complexity, organisational strategies and task-switching on the task-span procedure
… long-term memory, and action. Using the task-span procedure developed by Logan (2004), the current thesis aimed to examine some of the most salient features of working memory. Specifically how processing and storage interact with working memory, the influence of organisational factors on …

Controlling memory and resolving interference : prefrontal contributions to flexible behavior
Flow does the brain meet shifting task demands? The experiments and formal theoretical framework presented in this dissertation characterize the cognitive and neural processes by which flexible performance is enabled during task switching. Chapter 1 reviews major findings and controversies in the …

Multilingualism and Diglossia in Hong-Kong Secondary Schools: Switching effects in cognition and language processing
The bilingual advantage in cognitive switching has been extensively documented in the literature (e.g., Bialystok, 2011; Bialystok, 2015). This thesis focuses on the cognitive gains of bilinguals in task-switching, specifically. If we assume that bilinguals outperform monolinguals in non-verbal …

Effects of music and dance training on executive functions in children
… of working memory, interference control, and task switching. Children between 6-9 years old were randomly assigned to music or dance groups, and tested on executive functions before and after training. Following training, significant decreases in global and local switch cost were observed, but …

The Association Between Musical Training, Bilingualism, and Executive Function

Your Attention Please: Neural Networks, Individual Differences, and Clinical Implications of Attentional Control in the Human Brain
… without allowing external stimuli to lure us off task. Yet, we must also be able to shift our attention flexibly to switch tasks in response to relevant cues. Unitary accounts of attention maintain that these abilities rely on similar or identical neurocognitive mechanisms, while fractionated …

Data-driven task allocation for multi-robot deliveries
In this thesis, we present a distributed task allocation system for a team of robots serving queues of tasks in an environment. We consider how historical information about such a system's performance could be used to improve future allocations. Our model is representative of a multi-robot mail …

DOES LIFETIME ENGAGEMENT IN PHYSICAL ACTIVITY AFFECT EXECUTIVE COGNITIVE FUNCTION IN OLDER ADULTS?
… performed three executive cognitive function tasks (Flanker, Task Switching, and Stopping). Results: Executive cognitive function was different (p < 0.05) between Masters Swimmers and controls for flanker task trials (incongruent and congruent) and task switching. No differences between groups …

Investigating and Characterising the Impact of Vehicle Interfaces on Situation Awareness
… Related Activities (NDRAs), resulting in multitasking. How NDRAs are achieved will depend upon whether In-Vehicle Information Systems (IVIS) are available. If not, alternative means may be taken that could compromise Driving Related Activity (DRA) performance. Situation Awareness (SA) is …

Manipulations of task switches during acquisition: A test of the elaboration hypothesis of contextual interference
… Shea, Kohl, & Indermill, 1990) and the order of task presentation during practice has been determined to be critical in skill retention. Specifically, presenting a subject with several versions of a task typically produces poorer performance during practice but superior performance during …

Executive control: an electrophysiological investigation of control processes
