An "Oblique Effect" in infants' haptic perception of spatial orientations.
The present research addresses the question of the "oblique effect" (better discrimination of the vertical orientation than of an oblique orientation) in manual haptic perception of orientations (without visual control) by 5-month-old infants. A familiarization/reaction to novelty procedure was used. The results revealed the occurrence of a haptic oblique effect. These findings are similar to t...
متن کاملHaptic Exploration and the Perception of Texture Orientations
The perceptual sensitivity of touch to orientation differences in adjacent segments of textures with different configurations was measured in two experiments. We found that sensitivity to the orientation difference was not only a function of the magnitude of that difference but of the reference orientation. In Experiment 1, we examined the exploratory patterns that were used to make these judgm...
متن کاملHaptic perception of spatial relations.
There are some indications that haptic space like visual space is not Euclidean (e.g. Blumenfeld, 1937 Acta Psychologica 2 125-174). In a series of experiments, we investigated the haptic perception of spatial relations in a systematic way. We restricted ourselves to a horizontal plane at waist height. Blindfolded subjects were asked to perform three tasks with their right hand: (i) a reference...
متن کاملSpatial imagery in haptic shape perception.
We have proposed that haptic activation of the shape-selective lateral occipital complex (LOC) reflects a model of multisensory object representation in which the role of visual imagery is modulated by object familiarity. Supporting this, a previous functional magnetic resonance imaging (fMRI) study from our laboratory used inter-task correlations of blood oxygenation level-dependent (BOLD) sig...
متن کاملNoninformative Vision Improves Haptic Spatial Perception
Previous studies have attempted to map somatosensory space via haptic matching tasks and have shown that individuals make large and systematic matching errors, the magnitude and angular direction of which vary systematically through the workspace. Based upon such demonstrations, it has been suggested that haptic space is non-Euclidian. This conclusion assumes that spatial perception is modality...
