Rasch-Built Measure of Pleasant Touch through Active Fingertip Exploration
BACKGROUND Evidence suggests that somatic sensation has a modality for pleasant touch. OBJECTIVE To investigate pleasant touch at the fingertip level (i.e., glabrous skin site) through the elaboration of a linear unidimensional scale that measures (i) various materials according to the level of pleasantness they elicit through active fingertip explorations and (ii) subjects according to their...
متن کاملPhysical Factors Influencing Pleasant Touch during Passive Fingertip Stimulation
OBJECTIVE Tactile explorations with the fingertips provide information regarding the physical properties of surfaces and their relative pleasantness. Previously, we performed an investigation in the active touch domain and linked several surface properties (i.e. frictional force fluctuations and net friction) with their pleasantness levels. The aim of the present study was to investigate physic...
متن کاملPhysical Factors Influencing Pleasant Touch during Tactile Exploration
BACKGROUND When scanning surfaces, humans perceive some of their physical attributes. These percepts are frequently accompanied by a sensation of (un)pleasantness. We therefore hypothesized that aspects of the mechanical activity induced by scanning surfaces with fingertips could be objectively associated with a pleasantness sensation. Previously, we developed a unidimensional measure of pleasa...
متن کاملVicarious responses to social touch in posterior insular cortex are tuned to pleasant caressing speeds.
BACKGROUND Affective touch carries strong significance for social mammals, including humans. Gentle, dynamic touch of a kind that occurs during social interactions is preferentially encoded by a distinct neural pathway involving tactile C (CT) afferents, a type of unmyelinated afferent nerve found exclusively in hairy skin. CT afferents increase firing when the skin is stroked at a pleasant, ca...
متن کاملThe brain’s response to pleasant touch: an EEG investigation of tactile caressing
Somatosensation as a proximal sense can have a strong impact on our attitude toward physical objects and other human beings. However, relatively little is known about how hedonic valence of touch is processed at the cortical level. Here we investigated the electrophysiological correlates of affective tactile sensation during caressing of the right forearm with pleasant and unpleasant textile fa...
