Evaluating Model-Estimated Shoulder Muscle Activity During Overhead Work with Varied Task Demands and Exoskeleton Use
… that can reduce shoulder stress during overhead tasks. However, the effects of these devices are task- and device-specific, and current evaluation protocols remain time-consuming and resource-intensive. Musculoskeletal modeling could simplify the process of ASE evaluation, by replacing …

Alpha suppression as a neural marker of task demands in voluntary vs involuntary retrieval in older and younger adults
… group performing a sound localization task, and those in the voluntary group additionally attempting to recall the associated pictures. Participants later retrospectively reported which sounds brought the paired picture to mind during the sound task. Older adults said they remembered as …

The Influence of Task- Versus Self-Focus on Children's Achievement Performance and Attributions
… is that high-anxious persons attend less well to task demands, because they are overly preoccupied with self-doubt. Low-anxious persons focus more on task demands. The present research investigated how self-focus versus task-focus instructions influenced the performance and attributions for …

A framework for estimating difficulty and exclusion from tasks of everyday living
… design research and practice seeks to make tasks of everyday living more accessible for everyone. Identifying Performance Shaping Factors (PSFs) and assessing their impact on performance is central to estimating difficulty and potential exclusion from everyday tasks. The analysis of human …

A comparison of confirmatory factor analysis and task analysis of fluid intelligence cognitive subtests
… classifications have used data about subtest task demands. The purpose of this investigation is to determine whether subtest similarity judgments based on task demands data, and judgments based on ability measurement provide similar results. It includes two studies. First, middle school …

Aging and cortical recruitment in response to cognitive challenge
… age-related cortical recruitment is modulated by task demands, constrained by individual’s white matter integrity and external experience. In Experiment 1, I use the functional magnetic resonance imaging (fMRI) to reveal reduced BOLD-measured activity in older compared to young adults under …

Underspecification and parallel processing in sentence comprehension
… in sentence comprehension are sensitive to task demands. A central phenomenon in this regard is the so-called ambiguity advantage, which is the finding that ambiguous sentences can be easier to process than unambiguous sentences. This finding may appear counterintuitive, because more …

Neurology of Attention: Interhemispheric Processing Modulates Attention in the Stroop Task
… (1) is not a static, but instead varies with task demands, (2) produces non-random responses to attentional demands, and (3) is a unique form of neural processing not necessarily requiring a priori hemispheric asymmetries.

On the flexible nature of the relationship between attention and active memory representations
… these systems play and ignoring the role of task demands which include differences in factors such as context, task goals, or stimulus and response modalities. This restricted view has far-reaching consequences across many topics central to cognitive psychology such as (1) attention’s role in …

Sex-related differences in perception and discrimination of different speakers: An analysis of the auditory dorsal stream via EEG
<p>Growing evidence that speech perception tasks elicit sensorimotor activity, and that this activity varies due to context, sex, cognitive load, and cognitive ability. However, it is unknown as to whether the sex of the speaker and demands of the task differentially effect males and females during …

Eye movements in reading strategies : how reading strategies modulate effects of distributed processing and oculomotor control
… behavior induced by individual differences and task demands. This work introduces a novel comprehensive concept of reading strategy, comprising individual differences in reading style and reading skill as well as reader goals. In a series of sentence reading experiments recording eye movements, …

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 …

The effects of time of day and circadian rhythm on performance during variable levels of cognitive workload
… time of day of testing on a simulated aviation task. The tasks required the participants to engage in multitasking while electroencephalogram (EEG) data was collected to objectively measure participants’ workload. Task demands were altered throughout the testing period to expose participants to …

Parietal contributions to visual working memory depend on task difficulty
… tDCS improved performance in a change detection task, and cathodal current tDCS impaired performance on a sequential presentation task. Here, we tested whether these complementary results were due to different degrees of parietal involvement as a function of WM task demands, WM task difficulty …

Sensorimotor Modulations by Cognitive Processes During Accurate Speech Discrimination: An EEG Investigation of Dorsal Stream Processing
… responds to cognitive processes in service of task demands. The purpose of the current study was to identify the influences of attention and working memory on sensorimotor activity across the dorsal stream during speech discrimination, with set size and signal clarity employed to modulate …

Individual Differences in Inhibitory Control Skills at Three Years of Age
… the impact that nonverbal and/or motivational task demands had on child IC task performance. Furthermore, task performance was examined with respect to measures of language, temperament, and psychophysiology. Tasks showed different patterns of relations to each of these variables. Furthermore, …

Adverse childhood experiences, working memory, and stress
… (ACEs), working memory as assessed by an n-back task, and stress. Working memory task demands were manipulated by varying the cognitive load (1-back/3-back) and time limit (standard-paced/time-restricted), and stress was measured both subjectively via self-report and objectively via heart rate …

The effect of extended reach on manual arm strength
… in occupational settings, particularly in tasks requiring repetitive arm movements, forceful exertions, and prolonged postures. Manual arm strength (MAS) predictions, from ergonomics tools such as the Arm Force Field Method, supports ergonomics analyses by comparing manual force task …

Exploring subjective and objective localized muscle fatigue responses at recommended upper limb ergonomics limits
… negative outcomes, including a reduction in task performance and development of musculoskeletal injury. Thus, the quantification of LMF development in response to occupational task demands has become a major focus in the ergonomics literature. In this thesis, Study 1 showed how a …
