Human information processing efficiency in a dual-task paradigm
… Regan, and Lee (1989) have presented a dual-task paradigm which they claim enabl JS a strict test of the single-channel hypothesis. In this paradigm, subjects perform two serial choice reaction time (RT) tasks, first separately, and then simultaneously, at their maximum sustainable rates …

The Attentional Demands of Positive Reappraisal in a Dual Task Paradigm
… before an emotion fully develops, individuals have the potential to alter the extent to which they feel certain emotions. This strategy has been associated with a wide array of beneficial health and psychological outcomes, and is also used in treating different forms of psychopathology. …

Development of Realistic Stimuli for the Evaluation of Listening Effort using Auditory Evoked Potentials
… examined with psychophysiological measures, a dual-task paradigm, and qualitative measures using a variety of auditory stimuli ranging from simple tonal stimuli to complex speech stimuli, such as consonant-vowel syllables, words, and full sentences, but never in the context of a conversation. …

Dual-task interference and its influence on deception detection and memory
Using a dual-task paradigm, I examined how engaging in executive function tasks impacted deception detection and memory performance. University students (N = 185) were randomly assigned to detect deception while also performing a concurrent monitoring, memory, planning, motor, or visual task, or no …

Resource allocation in dysthymia and anhedonia
… research has shown that dysthymic individuals are hyporesponsive during information processing tasks. This can be interpreted as evidence of a deficit in the availability or allocation of processing resources. The present research addressed this possibility by comparing dysthymics to …

Private Speech and Inner Speech in Typical and Atypical Development
… of private speech in combination with the dual task paradigm to assess the extent to which the executive function of planning is reliant on SDS in typically developing 7- to 11-year-olds. Chapters 3 and 4 describe studies investigating the SDS of two groups of atypically developing children …

The Effects of Attentional Load and Anxiety on Aiming Task Performance in Sport
… skills during performance in aiming tasks were examined in the current thesis. Firstly, due to a lack of research within the area, Chapter two investigated expertise differences and the effect of task complexity on visual search behaviours, movement kinematics during golf short game …

The Effects Of Secondary Task Demandon The Assessment Of Threat
… is blurred, it becomes more important for individuals to clearly distinguish between those who would present danger and those who would not. This series of experiments tested whether observers engaged in a dual-task paradigm perceived a greater amount of threat from target stimuli than they did …

Visual Working Memory and Visual Selective Attention among Survivors of Pediatric Acute Lymphoblastic Leukemia (ALL)
… aspects of VWM and visual selective attention. A dual-task paradigm, combining a VWM task and a flanker task, assessing visual selective attention, was used. Participants ran in 6 dual-task conditions that varied in VWM feature/task (color, shape, location) and of the flanker feature/task (color, …

The Effects of Fitness Differences and Fitness Training on Dual-Task Performance and the Brain Processes of Older Adults
… of aging humans on a well-characterized dual-task paradigm. Functional magnetic resonance imaging scans were collected on all older adults in a paradigm in which participants were asked to judge both letters and numbers. Consistent with extant literatures on cardiovascular fitness, …

Training-Induced Changes in Dual -Task fMRI Activation in Young and Old Adults
… correlates of training-related improvements in dual-task processing in older and younger adults. The first study consisted of untrained younger adults with the goal to discriminate between cortical regions involved in preparing to make more than one response from those involved in the management …

Warning Compliance: Effects Of Stress And Working Memory
… warning presentation and retention in a dual-task paradigm in a simulated military environment under various task-induced stress levels. It was also intended to determine what role working memory played in the mode of warning presentation that resulted in the highest retention and …

Effects of Aging on Behavioral Measures of Listening Effort
… in noise is a common problem among elderly individuals. Older adults often report challenges with understanding speech, particularly in noisy environments. Growing evidence suggests that cognitive effort is a significant factor in speech understanding in noise. Although hearing loss is commonly …

The Effects of Concurrently Performing Balance and Cognitive Tasks Across the Life Span
A dual-task paradigm involving a primary sensorimotor task and a secondary cognitive task was used to examine the effect of age and task difficulty on the relationship between balance and cognition. We investigated twenty healthy children (mean age = 9.0 +/- 0.8), 20 young adults (mean age = 20.1 …

Effects of stimulus class on short-term memory workload in complex information display formats
… of stimulus class. Experiment 1 employed a dual-task paradigm where the primary task was compensatory tracking used to load STM and the secondary task was item recognition using the Sternberg paradigm. Experiment 2 employed a singletask paradigm using a modified version of the Sternberg …

Interférence cognitivo-motrice chez les personnes atteintes de sclérose en plaques
… to evaluate this interaction by using the dual-task paradigm (DT). Few studies have examined the effect of DT through the dual task cost (DTC) in people with MS. Specifically, the objectives of this thesis were to 1) determine the DTC of two tasks under different postural conditions in …

Age-Related Changes in Listening Effort for Various Types of Masker Noises
… in various types of background noise.</p> <p>A dual-task paradigm was used to objectively evaluate listening effort. The primary task required participants to repeat sentences presented in three different background noise masker conditions (e.g. Two-Talker (TT), Six-Talker (SIX), Speech-Shaped …

Testing the strength model of self-control: Does willpower resemble a muscle?
… decrements on subsequent self-control tasks. However, it is possible that this pattern of behaviour is confined to specific experimental procedures, which amplifies the effect. The aims of this thesis are to; 1) test the strength model predictions in sport; and 2) examine emotion as a …

Evaluating attention allocation in children to young adults with a single and dual task EEG paradigm
… allocate attentional resources between tasks has implications for participation in activities of daily living (ADLs) and instrumental activities of daily living (IADLs) across the lifespan. Neuroimaging techniques, such as electroencephalography (EEG) can measure cognitive processing …
