• An experimental investigation into the impact of Delphi group size and diversity. Focused on surveys that include exchange rationales between rounds. We explored effect opinion diversity panellists’ information (over)load experience process. For sizes up to 19 (whether with diverse opinions or not), we found no evidence overload, de-motivation disengagement. In this paper, investigate members...
The neuroimaging literature on dual-task gait clearly demonstrates increased prefrontal cortex (PFC) involvement when performing a cognitive task while walking. However, findings from direct comparisons of the cerebral oxygenation patterns of younger (YA) and older (OA) adults during dual-task walking are mixed and it is unclear how YA and OA respond to increasing cognitive load (difficulty) wh...
this study investigated the effects of manipulating the cognitive complexity of tasks along +/- few elements and the time limits on l2 learners writing performance. to conduct the study, 60 iranian efl learners with two levels of proficiency, low and high intermediate, were selected and assigned to three groups based on the time devoted to task completion. the participants performed both a simp...
The dual task is a data-rich paradigm for evaluating speech modes of a synthetic talking head. Three experiments manipulated auditory–visual (AV) and auditory-only (A-only) speech produced by text-to-speech synthesis from a talking head (Experiment 1—single task; Experiment 2—dual task), and natural speech produced by a human male similar in appearance to the talking head (Experiment 3—dual tas...
Emotionally arousing stimuli are perceived and remembered better than neutral stimuli. Under threat, this negativity bias is further increased. We investigated whether working memory (WM) load can attenuate incidental memory for emotional images. Two groups of participants performed the N-back task with two WM load levels. In one group, we induced anxiety using a threat of shock paradigm to inc...
High perceptual load in a task is known to reduce the visual perception of unattended items (e.g., Lavie, Beck, & Konstantinou, 2014). However, it remains an open question whether perceptual load in one modality (e.g., vision) can affect the detection of stimuli in another modality (e.g., hearing). We report four experiments that establish that high visual perceptual load leads to reduced detec...
This research showed that appropriate input and suitable contexts for interaction among students can lead to successful second language acquisition (SLA). This study based on Swain's (2005) notion of collaborative dialogue, aimed to study whether EFL learners participating in negotiation of meaning based tasks collaborate with each other and, if so, to investigate the role of this behavior in ...
Objective Stair ascent and descent is an essential movement task in daily life in which individuals are subjected to repetitive impact forces. The purpose of this study was to evaluate the intensity of Electromyographic (EMG) activity in lower extremity muscles of healthy young men during stair ascent and descent task wearing different type of shoes and carrying loads. Methods Nine men with a ...
