“…The difference found in the present study between EMG activity of the active (dominant) and the passive arm, as well as the difference between EMG activity in the active arm during imaginary lifting of 4.5 and 9 kg weights, indicates that the content of the image is related to the location and magnitude of the physiological response. These results suggest, contrary to the findings of Shaw (1938), that the physiological response is also specific within one response system a d reflects the spatial differentiation (between passive and active arm) and the quantitative characteristics of an image.…”

Investigating emotional imagery, Lang (1977Lang ( , 1979 proposed a dichotomy between stimulus and response propositions. In this study, Lang's model is applied to movement images of lifting of 4.5 and 9 kg weights. Twenty-two male and 17 female students participated in the study. During the imaginary lifting of the weights, the electromyographical activity (EMG) of both biceps brachii muscles were assessed. Imagery ability was measured with the Movement Imagery Questionnaire (MIQ) and another self-report rating scale. When response propositions were emphasized in the script, imaginary weight lifting resulted in greater muscle activity than when stimulus propositions were emphasized. During imagined lifting, EMG activity of the active arm was greater than that of the passive arm. In addition, in the active arm, a significant difference in EMG activity was found between 9 kg and 4.5 kg. It was concluded that Lang's model is also applicable to emotionally neutral movement imagery.

Even though earlier studies found a functional equivalence within the EMG activity (Jacobson, 1931;Shaw, 1940), none has reported an activation of all muscles involved in the production of the actual movement.…”

“…Such hypothesis has early been proposed by Washburn (1916), who suggested that slight muscle movements were made during MI, and later substantiated by several authors (Jacobson, 1931(Jacobson, , 1932Shaw, 1938), who have reported that this EMG activity occurred only in the muscles that are involved in the movement. In addition, the Golgi tendons organs may be stimulated, and thereby generate neuromuscular feedback (Schmidt and Lee, 1999).…”

Almraet--The working hypothesis of the paper is that motor images are endowed with the same properties as those of the (corresponding) motor representations, and therefore have the same functional relationship to the imagined or represented movement and the same causal role in the generation of this movement. The fact that the timing of simulated movements follows the same constraints as that of actually executed movements is consistent with this hypothesis. Accordingly, many neural mechanisms are activated during motor imagery, as revealed by a sharp increase in tendinous reflexes in the limb imagined to move, and by vegetative changes which correlate with the level of mental effort. At the cortical level, a specific pattern of activation, that closely resembles that of action execution, is observed in areas devoted to motor control. This activation might be the substrate for the effects of mental training. A hierarchical model of the organization of action is proposed: this model implies a short-term memory storage of a 'copy' of the various representational steps. These memories are erased when an action corresponding to the represented goal takes place. By contrast, if the action is incompletely or not executed, the whole system remains activated, and the content of the representation is rehearsed. This mechanism would be the substrate for conscious access to this content during motor imagery and mental training.
