During object manipulation tasks, the brain selects and implements action-phase controllers
that use sensory predictions and afferent signals to tailor motor output to the physical …

To be successful, precision manipulation of small objects requires a refined coordination of
forces excerted on the object by the tips of the fingers and thumb. The present paper deals …

… (Johansson & Vallbo, 1976; Vallbo & Johansson, 1978). Thus, it seems that the spatial
distribution of the RA and SA I units as well as their receptive field properties make these two …

A small object was gripped between the tips of the index finger and thumb and held stationary
in space. Its weight and surface structure could be changed between consecutive lifting …

… R olf Johansson … R olf Johansson … In architectural research, when the case is a physical
artefact, case studies often become more or less historical case studies (Johansson, 2000a). …

… The power function has the general form R = a Sb, where R is the intensity of the sensation
as estimated and reported by the subject and S is the stimulus magnitude (strictly, the …

We analyzed the coordination between gaze behavior, fingertip movements, and movements
of the manipulated object when subjects reached for and grasped a bar and moved it to …

Measurements were made from the human adductor pollicis muscle of force, contractile
speed, and electromyographic activity (EMG) before, during, and after maximal isometric …
