ABSTRACT Localizing touch on the skin requires integration of multiple spatial signals, including reference landmarks and motion cues. It is well known that patterns can bias perceived endpoint motion. However, it unknown whether static presented post‐motion also distorted. To investigate this, we space‐changing tested position perception 1 s 10 post‐motion. We used a brush moving along forearm at 15 cm −1 , brushing 4.5 patches near elbow wrist, skipping 10‐cm long metal‐shielded patch in...
Weak electrocutaneous stimuli applied to the forearm are erroneously localized toward its middle (Steenbergen P, Buitenweg JR, Trojan J, Veltink PH. Exp Brain Res 232: 597-607, 2014). We asked whether mechanical touch exhibit a similar bias and is of or recent stimulus distribution. In experiments 1 2, participants ( n = 12 10) by pointing von Frey filaments four locations on dorsal forearm. Individually adjusted weak strong experiment 1) two levels 2) were presented in single sessions...
We investigated the influence of motion context on tactile localization, using a paradigm similar to cutaneous rabbit or sensory saltation (Geldard FA, Sherrick CE. Science 178: 178-179, 1972). In one its forms, stimulus consists tap in location quickly followed by another elsewhere, creating illusion that two taps are near each other. Instead taps, we used position halted brush and instead distance judgment, localization responses. The moved across skin left forearm, clear signal before...
Abstract The ability to track the time-varying postures of our hands and forces they exert plays a key role in dexterously interact with objects. However, how precisely accurately we sense hand kinematics kinetics has not been completely characterized. Furthermore, dominant source information about stems from muscle spindles, whose responses can also signal isometric force are modulated by fusimotor input. As such, one might expect that changing state muscles – for example, applying load...
Existing planet-finding spectrometers are limited by systematic errors that result from their seeing-limited design. Of particular concern is the use of multi-mode fibers (MMFs), which introduce modal noise and accept significant amounts background radiation sky. We present design a single-mode fiber-based acquisition camera for diffraction-limited spectrometer named "iLocater." By using "extreme" adaptive optics (AO) system Large Binocular Telescope (LBT), iLocater will overcome limitations...
Gestalt psychology inspired wide interest in processes of perceptual grouping and figure-ground organization. But while often mentioned together textbooks, these two topics have rarely been directly related. Figure-ground organization is usually discussed terms local properties on one or the other side an edge that may determine to which becomes assigned. Perceptual linking otherwise discontinuous elements image. Here we address whether assignment might be affected by relations between...
Since Egly, Driver and Rafal's (1994) pioneering study of object-based attention, their two-object cueing design has been widely used to space- attentional orienting. Here, patients with unilateral brain injury performed target detection in a modified version the task. By obliquely orienting two rectangular objects ±45°, we were able measure performance separately at midline, contralesional field, ipsilesional field. Cues 64% predictive always appeared an upper or lower midline location. For...
