Mental imagery is the human ability to imagine and reason with visuo-spatial information. It is crucial for everyday tasks such as describing a route or remembering the form of objects. The so-called imagery debate has been centered around the question how mental imagery is realized, i.e., what structures and algorithms can plausibly explain and model mental imagery. There is, however, little p...

This study replicated and extended previous data suggesting that worry inhibits emotional processing of fearful imagery. Female participants categorized as either victimization-fearful (N = 24) or victimization and speech-fearful (N = 27) completed trials of worrisome or relaxing thinking and tone-cued imagery. For each trial, participants engaged in 30 s of relaxing or worrisome (speech or vic...

Aims. While studies on healthy subjects have shown a partial overlap between the motor execution and motor imagery neural circuits, few have investigated brain activity during motor imagery in stroke patients with hemiparesis. This work is aimed at examining similarities between motor imagery and execution in a group of stroke patients. Materials and Methods. Eleven patients were asked to perfo...

Previous research has shown that readers generate mental images of events. Most studies have investigated imagery during the reading of short texts, which also included explicit judgment tasks. In two fMRI studies, we assessed whether modality-specific imagery occurs during naturalistic, discourse comprehension. We identified clauses in the texts that elicited auditory, motor, or visual imagery...

the aim of this study was to investigate the effect of mental imagery and physical practice on dynamic balance in male patients with multiple sclerosis. this study was semi-experimental and the statistical population included male patients with multiple sclerosis in ahvaz city in 2012 (n=300). for sampling, visual and kinesthetic imagery questionnaire and edss scale were used. finally, 33 patie...

This paper examines the role of mental imagery in music performance. Self-reports by musicians, and various other sources of anecdotal evidence, suggest that covert auditory, motor, and/or visual imagery facilitate multiple aspects of music performance. The cognitive and motor mechanisms that underlie such imagery include working memory, action simulation, and internal models. Together these me...

Visual imagery and perception share several functional properties and apparently share common underlying brain structures. A main approach to the scientific study of visual imagery is exploring the effects of mental imagery on perceptual processes. Previous studies have shown that visual imagery interferes with perception (Perky effect). Recently we have shown a direct facilitatory effect of vi...

Biological motion perception is often claimed to support social cognition, and to rely upon embodied representations and motor imagery. Are people with higher levels of social traits or more vivid motor imagery better at biological motion perception? We administered four experiments measuring sensitivity in using (global) form and (local) motion cues in biological motion, plus well-established ...

Remembering past events - or episodic retrieval - consists of several components. There is evidence that mental imagery plays an important role in retrieval and that the brain regions supporting imagery overlap with those supporting retrieval. An open issue is to what extent these regions support successful vs. unsuccessful imagery and retrieval processes. Previous studies that examined regiona...

In recent years, several real-time or near real-time object detectors have been developed. However these object detectors are typically designed for first-person view images where the subject is large in the image and do not directly apply well to detecting vehicles in aerial imagery. Though some detectors have been developed for aerial imagery, these are either slow or do not handle multi-scal...
