Task preparation processes related to reward prediction precede those related to task-difficulty expectation
Recently, attempts have been made to disentangle the neural underpinnings of preparatory processes related to reward and attention. Functional magnetic resonance imaging (fMRI) research showed that neural activity related to the anticipation of reward and to attentional demands invokes neural activity patterns featuring large-scale overlap, along with some differences and interactions. Due to t...
متن کاملMeasuring mimicry in task-oriented conversations: degree of mimicry is related to task difficulty
The tendency to unconsciously imitate others in conversations has been referred to as mimicry, accommodation, interpersonal adaptation, etc. During the last few years, the computing community has made significant efforts towards the automatic detection of the phenomenon, but a widely accepted approach is still missing. Given that mimicry is the unconscious tendency to imitate others, this artic...
متن کاملthe evaluation of language related engagment and task related engagment with the purpose of investigating the effect of metatalk and task typology
abstract while task-based instruction is considered as the most effective way to learn a language in the related literature, it is oversimplified on various grounds. different variables may affect how students are engaged with not only the language but also with the task itself. the present study was conducted to investigate language and task related engagement on the basis of the task typolog...
15 صفحه اولFeedback-related potentials in a gambling task with randomised reward
Event-related potentials (ERPs) time-locked to decision outcomes are reported. Participants engaged in a gambling task (see [1] for details) in which they decided between a risky and a safe option (presented as different coloured shapes) on each trial (416 in total). Each decision was associated with (fully randomised) feedback about the reward outcome (Win/Loss) and its magnitude (varying as a...
متن کاملClosing the mind's eye: deactivation of visual cortex related to auditory task difficulty.
Blood oxygen-level-dependent signal decreases relative to baseline (deactivations) can occur with stimulation of an opposing sensory modality. Here, we show the importance of the difficulty of an auditory task on the deactivation of visual cortical areas. Participants performed an auditory temporal-order judgment task in conjunction with sparse-sampling functional MRI at both moderate and high ...
