The purpose of this research was to analyzing the perception and technical knowledge of wheat farmers in shoushtar township, Khouzestan province, Iran regarding organic farming products. The research method employed was correlative-descriptive. The population consisted of wheat farmers in Shoushtar township Khuzestan Province of Iran. A random sample of wheat farmers (n = 163) was selected. The...

We determined the effect of dot speed on the typical and atypical development of motion-defined form perception. Monocular motion coherence thresholds for orientation discrimination of motion-defined rectangles were determined at slow (0.1 deg/s), medium (0.9 deg/s) and fast (5.0 deg/s) dot speeds. First we examined typical development from age 4 to 31 years. We found that performance was most ...

Recent literature on Korean fricatives has shown that the perception of the plain /s/ over the fortis /s*/ correlates to low f0 onset of the following vowel, despite the fact that there is no such correlation in the production of /s/ over /s*/. The integration of f0 with other low frequency cues that covary more reliably with /s/ presents a possible explanation for this disparity between produc...

I applaud Firestone & Scholl (F&S) in calling for more rigor. But, although F&S are correct that some published work on top-down effects suffers from confounds, their sweeping claim that there are no top-down effects on perception is premised on incorrect assumptions. F&S's thesis is wrong. Perception is richly and interestingly influenced by cognition.
