The effects of visual impairment on motor imagery in children and adolescents
Research in Developmental Disabilities, 2021While the development of motor imagery (MI) has been extensively studied in sighted children, it is not clear how children with different severities of visual impairment (VI) represent motor actions by using the motor representations constructed through the remaining intact senses, especially touch.Mental chronometry and generation/manipulation of MI ...

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

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.

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 ...

Solving a mental rotation task in congenital hemiparesis: Motor imagery versus visual imagery
Neuropsychologia, 2007 A recent study showed that motor imagery was compromised after right congenital hemiparesis. In that study, posture of the displayed stimuli and the actual posture of the hand making the response were incongruent. Ample evidence exists that such an incongruency may negatively influence laterality judgements in a mental rotation task.

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 ...

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.

Visual Training Improves Motor Imagery Ability for Rehabilitation
2021 International Conference on Artificial Intelligence and Mechatronics Systems (AIMS), 2021Motor imagery (MI) is the most favorable brain action exploited in motor deficit rehabilitation. The hemodynamic response (HR) signal is usually weak, which can be enhanced with specific methods. In this research, the improvement in the HR was examined while the participants performed the MI task of right-hand movement.

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

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 ...
