Motor imagery and visual event recognition
Experimental Brain Research, 2000In order to investigate the influence of covert motor processes in the recognition of visual events, we compared the response times (RT) in two similar tasks, one involving a to-be-grasped object and the other involving a to-be-observed object. In one task, we asked right-handed subjects to tell whether an observed screwdriver presented in different ...

Brief Visual Deprivation Effects on Brain Oscillations During Kinesthetic and Visual-motor Imagery
Neuroscience, 2023It is widely recognized that opening and closing the eyes can direct attention to external or internal stimuli processing. This has been confirmed by studies showing the effects of changes in visual stimulation changes on cerebral activity during different tasks, e.g., motor imagery and execution.

Relationship between Visual and Motor Imagery
Perceptual and Motor Skills, 2007The relationship between visual and motor imagery was investigated by administering a battery of visual and motor imagery measures to a sample of 101 men ( n = 49) and women ( n = 52), who ranged in age from 18 to 59 ( M=34.5, SD=12.6). A principal components analysis applied to the correlation matrix indicated four underlying components, which ...

Estimating Reach via Visual Imagery and Motor Imagery
Journal of Imagery Research in Sport and Physical Activity, 2008With the present study we compared the use of motor imagery (MI) and visual imagery (VI) in estimating reach. There are indications that with MI there is a visual (action) processing advantage. Alternatively, one could speculate that due to a lifetime of experience with reaching within one's peripersonal space, the difference between imagery techniques

Postural Control During Visual and Kinesthetic Motor Imagery
Applied Psychophysiology and Biofeedback, 2011Despite the accumulating evidence supporting an interaction between cognitive functions and postural control, little is known about the selective impact of the mental representation of an action, i.e., motor imagery (MI) on postural control. As postural oscillations are reduced during a cognitive task of backward silent counting, a greater stability is

Visually guided motor imagery activates sensorimotor areas in humans
Neuroscience Letters, 1999Stimulus-related changes in ongoing electroencephalography (EEG) over sensorimotor areas were investigated during a visually cued motor imagery task. Four subjects were instructed to imagine one-sided hand movements in response to visual cue stimuli. The EEG was recorded from central areas using 27 electrodes set at distances of 2.5 cm.

Exploring motor and visual imagery in Amyotrophic Lateral Sclerosis
Experimental Brain Research, 2013Amyotrophic Lateral Sclerosis (ALS) is a motor neuron disease characterized by the progressive atrophy of both the first and the second motor neurons. Although the cognitive profile of ALS patients has already been defined by the occurrence of language dysfunctions and frontal deficit symptoms, it is less clear whether the degeneration of upper and ...

Testing the Distinctiveness of Visual Imagery and Motor Imagery in a Reach Paradigm
International Journal of Neuroscience, 2009We examined the distinctiveness of motor imagery (MI) and visual imagery (VI) in the context of perceived reachability. The aim was to explore the notion that the two visual modes have distinctive processing properties tied to the two-visual-system hypothesis.

Controllability of Motor Imagery and Transformation of Visual Imagery
Perceptual and Motor Skills, 1994This study examined the relation between control of motor imagery and generation and transformation of visual imagery by testing 54 subjects. We used two measures of the Controllability of Motor Imagery test to evaluate the ability to control motor imagery. One was a recognition test on which the subject imagines as if one sees another's movement, and

Motor and Visual Imagery in Sports
2012Mental practice routines play an important role in many different sports, not only for the acquisition of motor skills but also for preparation prior to competitive events and rehabilitation after sport injuries. Imagery techniques in sport are used for different purposes, as outlined by the Model of Imagery Use in Sports [Martin et al.
