Functional cerebral asymmetry: a test of the selective activational model
… was found in these experiments, though experimental tasks had significant interference effects. In Experiment 1, non-specific interference effects were found across visual fields for both experimental tasks, suggesting the hemispheres were not preferentially recruited. Right visual field …

A study of story schema acquisition and its influence on beginning reading
… of story information. A series of four experimental tasks were administered individually at the start of the academic year and again at the end to each of the 156 four, five, six and seven year olds in the sample. Tasks chosen were selected on the basis of research suggesting their …

Cognitive Processes in Second Language Reading (Orthography, Cognition, Bilingualism)
… English, Japanese, and Spanish (N = 83). Experimental tasks involved (a) short-term memory recall, (b) reading with Sanskrit symbols, (c) lexical decision-making, and (d) reading with heterographic homophones. The results consistently demonstrate that the four groups utilize different …

Setting location priors using beamforming improves model comparison in MEG-DCM
… insight into the activity of the brain during experimental tasks. Magnetoencephalography (MEG) allows for the observation of the fast neuronal dynamics necessary to characterize the activity of sources and their interactions. A network representation of these sources and their connections can …

Attentional biases in post traumatic stress disorder and following acquired brain injury
… into attentional biases across arange of experimental paradigms.Methods: A systematic search of four key databases identified 30 papers meetingthe inclusion criteria. Methodological quality of selected articles was assessedusing an adapted checklist. The tasks employed in the studies were …

Event-Related Potentials Correlated with State/Trait Anxiety Using Auditory Stimuli
… research has focused on anxiety, visual stimuli, experimental tasks, and how ERP components relate to them. Few of the studies used auditory stimuli. This study proposes that the P2, P3, and late positive potential (LPP) ERP components will have greater amplitude when unpleasant auditory stimuli …

Real Work Task Performance: The Role of Abilities, Non-Ability Traits, and Proximal Variables
… of adult intelligence that are representative of tasks that adults might encounter in their everyday lives. In order to accomplish this objective, 59 undergraduate students (35 male, 24 female) completed three hands-on, experimental tasks that were designed to be realistic and sample a variety of …

Redesigning Airport Diagrams with Principles of Cognitive Psychology
… and deviations throughout six simulated taxiing tasks. The results were not statistically significant. The results showed evidence of a ceiling effect which may indicate that the taxiing tasks were too easy to show performance differences. This research issues should not be abandoned. However, …

Crowdsourcing data collection through mobile gamification : leveraging the freemium model
… who use the in-game rewards were motivated to do experimental tasks. The data showed that there was no difference between the groups for performance on a motor task; however, performance on a cognitive task was worse for the crowdsourced Android group. We discuss the possible reasons for this and …

Relations Among Endogenous Attention, Executive Functioning, and Global Assessment Measures in Toddlers and Preschoolers Born Full-Term and Preterm
… are many different components of attention, and experimental tasks eliciting specific abilities may be more useful in detecting differences between term and preterm children</p><p>Participants were 81 toddlers and preschoolers born full-term and preterm. Children completed a battery of …

Effects of training methods on classification on surface electromyographic signals for myoelectric control
… affect two subjects' performance on various experimental tasks and their measured sEMG activation throughout the tasks. It was found that for subject 1, the assisted training method, where another individual helps move the orthosis while training the KNN, resulted in a lower variance in the …

Towards a more comprehensive understanding of adults’ responses to infant cues adopting a multi-method and non-heteronormative approach
… behaviors. Methodologies encompassed cognitive experimental tasks, EEG, standardized observations, and self-reported measures. Samples included non-parents, different-sex parents, and same-sex parents. Overall, the present work responded to the recent interest in understanding adults’ responses …

Dual Mechanisms of Cognitive Control: A Hierarchical Bayesian Approach to Test-Retest Reliability
… no existing theory of cognitive control unifies experimental and individual differences approaches. Some even argue that cognitive control as a psychometric construct does not exist at all. These disparities may exist in part because individual differences research in cognitive control utilizes …

Attributional style: a comparison of assertive and aggressive children
… purposes of the present study. First, quasi-experimental tasks assessing attributional style were used to investigate the mediating role of social cognitive processes in aggressive behavior for both boys and girls. Secondly, the use of current self-report measures of children's assertive and …
