Although subjects responded more slowly and less accurately than in Experiments I and II, they nevertheless discriminated relatively more novel from relatively more familiar pictures across all contexts (see Supporting Information Table S1 for RTs, hit-rates, FA-rates, and d'-values).
This is not altogether surprising, because the color differences between stimulus males were relatively large, easily discriminated by human observers, and likely outstripped any of the carotenoid-related shifts in discriminability.
During close-range mating behaviour experiments, males showed relatively weak species discrimination but females discriminated very strongly.
In this, relatively small sample, PI discriminated between those tumours that have subsequently metastasised and those that have not done so after at least 6 years.
Such experiments reveal that cats are relatively incapable of discriminating warm and cold stimuli applied to the furred skin of the trunk or the legs.
The results, from both the numerical finite element simulation and experimental test, indicate that the soft-thresholding process is capable of effectively reducing the effect of noise, convincingly improving the sensitivity of damage identification, and discriminating relatively small damage.
Measures of sensitivity and response bias revealed that participants took a conservative strategy that minimized false alarms, perhaps due to the fact that it was relatively easy to discriminate between fragmented and scrambled images.
All auditory and visual stimuli were relatively easy to discriminate.
In particular professionalism items were relatively poor at discriminating between candidates.
Therefore, it is relatively difficult to discriminate between a true copy-number gain and random experimental noise.
