Though emotions are often morally appraised and judged in everyday life among individuals, within the moral responsibility community this comes in direct conflict with the commonly held belief that moral responsibility requires some form of volitional control. Angela Smith argues that volitional control is not a key factor in responsibility but depends upon an agent’s evaluat ive judgments. She...

During prolonged observation of an ambiguous figure sudden perceptual reversals occur, while the stimulus itself stays unchanged. There is a vivid debate about whether bottom-up or top-down mechanisms underlie this phenomenon. In the present study, we investigated the interrelation of two experimental factors: volitional control and discontinuous stimulus presentation. Both factors strongly mod...

The antisaccade task is a measure of volitional control of behavior sensitive to fronto-striatal dysfunction. Here we outline important issues concerning antisaccade methodology, consider recent evidence of the cognitive processes and neural mechanisms involved in task performance, and review how the task has been applied to study psychopathology. We conclude that the task yields reliable and s...

Successful operation of brain-computer interfaces (BCI) and brain-machine interfaces (BMI) depends significantly on the degree to which neural activity can be volitionally controlled. This paper reviews evidence for such volitional control in a variety of neural signals, with particular emphasis on the activity of cortical neurons. Some evidence comes from conventional experiments that reveal v...

INTRODUCTION Asynchronous stimulation has been shown to reduce fatigue during electrical stimulation; however, it may also exhibit a force ripple. We quantified the ripple during asynchronous and conventional single-channel transcutaneous stimulation across a range of stimulation frequencies. METHODS The ripple was measured during 5 asynchronous stimulation protocols, 2 conventional stimulati...

It was long believed that central arrows needed to be spatially predictive to produce a shift in spatial attention. Recent evidence indicates, however, that central spatially nonpredictive directional cues, like arrows, will trigger reflexive shifts in attention. We asked what this recent discovery means for past studies that used predictive directional cues such as arrows. Our findings indicat...

Abstract – Neural sensorimotor systems have unavoidable delay in the processing. In this paper, we investigate the influence of the delay on control performance in numerical experiment with simple networks. Obtained results suggest not only the fact that the delay degrades control performance of reflex motion in proportion to the amount of the delay, but also the possibility that it influences ...
