Latency for categorization and identification, invariance to scale and position
Classifier performance as a function of cumulative time from stimulus onset for classification (red) and identification (blue) for the standard condition (solid lines) or invariance to scale and position (dashed dotted lines). Bin size = 12.5 ms, n=64 sites. The performance values are shown in the center of the corresponding bin. Error bars = s.d. for 20 random choices of sites. The dashed line shows the chance performance levels (1/8 for classification and 1/77 for identification). The red and blue areas near the dashed lines show the range of performances for the 100 ms time interval before stimulus fonset.
