“…These biases may be the result of misperception of limb movement. In this respect, differences between active and passive perception have been found (Gritsenko, Krouchev, & Kalaska, 2007). In this study, the subjects had to match movements of the elbow joint that were perceived actively or passively.…”

Mass can be perceived in different ways: statically, through gravitational cues; dynamically, through inertial cues; or a combination of both. This article investigates the relationship between these modes of perception. In three different experiments, subjects matched masses that were held statically in the hand to masses that were either accelerated or decelerated. Accelerated masses were perceived to be smaller than masses of equal physical magnitude held statically by a factor of 2. However, decelerated masses were matched veridically to masses held statically. This difference remained present when contact duration was made very short. This shows that the shift in perceived mass is not the result of differences in the information available, but of differences in the mode of perception (active acceleration vs. passive deceleration). It is hypothesized that this is due to a suppression of the perception of applied force in active touch.

“…In active touch, the subject controls the movement of the finger on the stimulus surface. An accurate movement can be made when the efferent copy of the outgoing motor command is integrated with afferent sensory information (Flanagan, Bowman, & Johansson, 2006;Gritsenko, Krouchev, & Kalaska, 2007;Wolpert, Ghahramani, & Jordan, 1995). In passive dynamic touch, the movement is supplied by an external agent.…”

Transfer of the curvature aftereffect in dynamic touch

a b s t r a c tA haptic curvature aftereffect is a phenomenon in which the perception of a curved shape is systematically altered by previous contact to curvature. In the present study, the existence and intermanual transfer of curvature aftereffects for dynamic touch were investigated. Dynamic touch is characterized by motion contact between a finger and a stimulus. A distinction was made between active and passive contact of the finger on the stimulus surface. We demonstrated the occurrence of a dynamic curvature aftereffect and found a complete intermanual transfer of this aftereffect, which suggests that dynamically obtained curvature information is represented at a high level. In contrast, statically perceived curvature information is mainly processed at a level that is connected to a single hand, as previous studies indicated. Similar transfer effects were found for active and passive dynamic touch, but a stronger aftereffect was obtained when the test surface was actively touched. We conclude that the representation of object information depends on the exploration mode that is used to acquire information.

“…In the auditory modality, when subjects compare the loudness of two identical sounds-one produced by actively pressing a button and the other perceived passivelythe sound in the active condition is reported as being less loud 9 . In contrast, proprioceptive sensation has been shown to be enhanced during self-generated movements, with fewer errors made regarding spatial hand position when hand displacement is self-generated compared with passive displacement 10 .…”

Lateralized enhancement of auditory cortex activity and increased sensitivity to self-generated sounds

et al. 2014

Performing actions with auditory consequences modulates the response in auditory cortex to otherwise identical stimuli passively heard. Such modulation has been suggested to occur through a corollary discharge sent from the motor cortex during voluntary actions. However, the relationship between the effector used to generate the sound, type of modulation and changes in perceptual sensitivity are unclear. Here we use functional magnetic resonance imaging on healthy subjects and demonstrate bilateral enhancement in the auditory cortex to self-generated versus externally generated sounds. Furthermore, we find that this enhancement is stronger when the sound-producing hand is contralateral to the auditory cortex. At the behavioural level, binaural hearing thresholds are lower for self-generated sounds and monaural thresholds are lower for sounds triggered by the hand ipsilateral to the stimulated ear. Together with functional connectivity analysis, our results suggest that a corollary discharge sent from active motor cortex enhances activity in the auditory cortex and increases perceptual sensitivity in a lateralized manner.
