Spatial frequency channels derived from individual differences
Contrast sensitivity functions differ from observer to observer. We propose that these differences arise because each observer has unique weights for the outputs of the neural channels that underlie the contrast sensitivity function. By applying principal components analysis to individual contrast sensitivity functions of 297 observers, estimates of the channel tuning curves were found. We find...
متن کاملIndividual Differences in Contrast Sensitivity Functions: The Lowest Spatial Frequency Channels
The number and nature of spatial channels tuned to low spatial frequencies in photopic vision was examined by measuring individual differences in the contrast sensitivity functions (CSFs) of seven visually normal adults. Stationary, 51 cd/m2, low spatial frequency sinusoidal gratings between 0.27 and 2.16 c/deg were used as stimuli. Correlational and factor analyses revealed that the set of CSF...

Computer-simulated environments hold promise for training people about real-world spaces. However, relatively little research has examined the role of user characteristics and abilities in determining the effectiveness of these virtual environments (VE’s) for training spatial knowledge. A correlational study is reported in which the relationships between the following factors are explored: pape...
متن کاملLow-spatial-frequency channels and the spatial frequency-doubling illusion.
PURPOSE This study examined the number and nature of spatiotemporal channels in the region where the frequency-doubling (FD) illusion would be expected to occur at eight locations spanning the central 30 degrees of the visual field. METHODS The probability of seeing the FD illusion was examined in 17 subjects. Stimuli were presented at 5 octaves of low spatial frequencies, at each of seven fl...
متن کاملStereopsis from Interocular Spatial Frequency Differences is Not Robust
Based on data obtained using one-dimensional noise patterns, Tyler & Sutter (1979). (Vision Research, 19, 859-865) concluded that stereoscopic tilt can result from an interocular spatial frequency difference in the absence of consistent horizontal disparity. We tested stereopsis using two-dimensional random-dot patterns that were bandpass filtered to contain 1.0 octave bands of spatial frequenc...
