EEG Alpha Asymmetry: Task Difficulty and Hypnotizability

Perceptual and Motor Skills, 1986
Parieto-occipital EEG alpha was recorded bilaterally, while 20 high- and 20 low-hypnotizable women performed one left-hemisphere and one right-hemisphere task of low difficulty and two other comparable tasks of high difficulty. Every task was performed twice, once with eyes open and once with eyes closed. All subjects were right-handed. The tasks were

Predicting Task Difficulty Through Psychophysiology

2021
Mental task solving is accompanied by physiological responses. These are not only indicative of a stressful situation, but are supposedly related to cognitive load as well. The present pilot study assessed the feasibility of establishing the relationship between chosen physiological parameters and the difficulty of science-related tasks assessed by ...

Enabling Uneven Task Difficulty in Micro-Task Crowdsourcing

Proceedings of the 2018 ACM Conference on Supporting Groupwork, 2018
In micro-task crowdsourcing markets such as Amazon's Mechanical Turk, how to obtain high quality result without exceeding the limited budgets is one main challenge. The existing theory and practice of crowdsourcing suggests that uneven task difficulty plays a crucial role to task quality.

Subjective Estimation of Task Time and Task Difficulty of Simple Movement Tasks

Journal of Motor Behavior, 2016
It has been demonstrated in previous work that the same neural structures are used for both imagined and real movements. To provide a strong test of the similarity of imagined and actual movement times, 4 simple movement tasks were used to determine the relationship between estimated task time and actual movement time.

Brief Report: Manipulation of Task Difficulty in Inhibitory Control Tasks

Child Neuropsychology, 2008
The present study investigated how task difficulty can be manipulated in inhibitory control tasks. Tasks from three widely used task paradigms - a Go/No-Go task, a Stop-Signal task,and a Flanker task - were manipulated on two parameters each (Go/No-Go task: interstimulus interval, prepotency. Stop-signal task: stop-signal-delay, prepotency.

Nonverbal Displays as Indicants of Task Difficulty

Contemporary Educational Psychology, 2001
Accurately determining when students are having difficulty with cognitive tasks is important in educational settings. This study investigated whether college students emitted observable displays of cognitive difficulty when engaged in solitary problem-solving tasks.

Hostile Press, Need Achievement and Task Difficulty

Psychological Reports, 1968
An experiment was conducted to determine the effects of task difficulty on achievement when ability and two types of motivation, Hostile Press and need achievement, are varied. It was found that Ss of high Hostile Press generally achieved more than Ss of high need achievement and the latter more than Ss of low need achievement. Ss of both high Hostile

P3a from visual stimuli: Task difficulty effects

International Journal of Psychophysiology, 2006
The P3a event-related brain potential (ERP) was elicited using a visual three-stimulus oddball paradigm (target, standard, distracter) in which participants responded only to the target. Discrimination task difficulty between the target and the standard was manipulated by varying the size of the standard stimulus circle relative to a constant target ...

Seniors' Attributions for Task Performance Difficulties

Journal of Aging and Health, 1996
Some seniors face difficulties carrying out simple everyday tasks such as opening containers and turning doorknobs. This study began with the premise that seniors' appraisals about such difficulties may have consequences for feelings of task efficacy (e.g., feelings of control and optimism).

EEG asymmetry as a function of occupation, task, and task difficulty

Neuropsychologia, 1975
Abstract Nine male artists and eight male engineers were tested for asymmetry of occipital alpha as a function of occupation, lateral speicificity of task, and difficulty of the task. NEbes' ring test and a facial memory test were used as “right hemisphere” tasks, and linguistic and mathematical tasks were chosen as left hemisphere specific.
