Importance of temporal cues for tactile spatial- frequency discrimination.
While scanning a textured surface with fingers, tactile information is encoded both spatially, by differential activation of adjacent receptors, and temporally, by changes in receptor activation during movements of the fingers across the surface. We used a tactile discrimination task to examine the dependence of human tactile perception on the availability of spatial and temporal cues. Subjects...
متن کاملDiscrimination of Low-Frequency Tones Employs Temporal Fine Structure
An auditory neuron can preserve the temporal fine structure of a low-frequency tone by phase-locking its response to the stimulus. Apart from sound localization, however, much about the role of this temporal information for signal processing in the brain remains unknown. Through psychoacoustic studies we provide direct evidence that humans employ temporal fine structure to discriminate between ...
متن کاملFour Paradigms of Information Systems
All systems developers approach the development task of systems failures. (The importance of implicit assumpwith a number of explicit and implicit assumptions tions has also been noted more generally in [3,4, 76, about the nature of human organizations, the nature of 80, 891). We agree with the previous research that a the design task, and what is expected of them. These better understanding of...
متن کاملSpatial frequency discrimination in schizophrenia.
Pathways within the visual system can be distinguished on the basis of selectivity for low or high spatial frequencies. Spatial frequency discrimination was evaluated in 17 medicated male patients with schizophrenia and 19 male control subjects. Subjects were required to discriminate whether pairs of high contrast, sinusoidally modulated gratings were the same or different in spatial frequency....
متن کاملFrequency discrimination in the chinchilla.
Chinchillas were trained with shock-avoidance procedures to discriminate or detect pure-tone frequency differences. Inital attempts at determining frequency-difference thresholds utilized a complex discrimination paradigm and a go-no-go response. Although discriminations of large frequency differences were obtained from chinchillas after considerable training, discriminations of small frequency...
