In this paper, differences between multichannel EEG signals of artists and nonartists were analyzed during visual perception and mental imagery of some paintings and at resting condition using approximate entropy (ApEn). It was found that ApEn is significantly higher for artists during the visual perception and the mental imagery in the frontal lobe, suggesting that artists process more informa...

BACKGROUND Placebo effects on pain are reliably observed in the literature. A core mechanism of these effects is response expectancies. Response expectancies can be formed by instructions, prior experiences and observation of others. Whether mental imagery of a response can also induce placebo-like expectancy effects on pain has not yet been studied systematically. METHODS In Study 1, 80 heal...

Mental imagery is receiving increased attention in consumer behavior theory and research. This article describes imagery, characterizing it as a processing mode in which multisensory information is represented in a gestalt form in working memory and discusses research on the unique effects of imagery at low levels of cognitive elaboration. It specifies researchable propositions for the relation...

One of our most remarkable mental capacities is the ability to use our imagination voluntarily to mimic or simulate sensations, actions, and other experiences. For example, we can “see” things in our mind’s eye,“hear”sounds in our mind’s ear, and imagine motor experiences like running away from, or perhaps “freezing” in the face of, danger. Since the early 1900s (1), researchers have investigat...

An exploratory, qualitative experiment sheds light on the depictive theory of mental imagery. The study analyzes the very operations subjects undertake when solving visuospatial tasks. Preliminary results indicate that subjects do not make use of stable mental images: instead, they continuously assemble and reassemble different perspectives through the guidance of heuristics and prototypes. The...

Visual mental images can be conceived of as mental models (in their Johnson-Lairdian sense, 1983) which involve both spatial and visual information (Kosslyn, 1980; 1994; Finke, 1989). Mental images are working memory constructions which are closely related to visual perception. The term is used to designate either imagery phenomena in the presence of actual visual perception, or those that are ...

Whether mental visual images play a functional role in cognition or that propositional knowledge is sufficient for supporting performance in imagery tasks is a long-standing debate. It cannot be resolved using behavioural data alone, nor by brain imaging data alone; for example, across fMRI studies mental rotation has been shown to involve virtually all areas of the brain. Alternatively partici...

Although motor imagery could improve motor rehabilitation, the detailed neural mechanisms of motor imagery cognitive process of stroke patients, particularly from functional network perspective, remain unclear. This study investigated functional brain network properties in each cognitive sub-stage of motor imagery of stroke patients with ischemic lesion in left hemisphere to reveal the impact o...

Although there is converging experimental and clinical evidences suggesting that mental training with motor imagery can improve motor performance, it is unclear how humans can learn movements through mental training despite the lack of sensory feedback from the body and the environment. In a first experiment, we measured the trial-by-trial decrease in durations of executed movements (physical t...
