Comments on Marken and Shaffer: The power law of movement: an example of a behavioral illusion
Many researchers who have studied movements along curved paths, under a variety of conditions, by different organisms, mostly human but a couple with non-human organisms, have found a consistent form of relati...

The prolactin releasing peptides: RF-amide peptides
Although dopamine is considered the major hypothalamic controller of prolactin release from the anterior pituitary gland, there is evidence that a yet to be discovered prolactin releasing factor (PRF) also ex...

A different function for a critical tryptophan in c-Raf and Hck
The similarity of the catalytic domains of Raf and Src family members suggests that functions of homologous residues may be similar in both kinase families. A tryptophan residue, W260, in the WEI region of the...

35S-Sulfide Incorporation During Alkaline Treatment of Keratin and its Relation to Lanthionine Formation
Cattle hair exposed to solutions of 35S-sulfide ions at pH 12.5, hydrolyzed with acid, and analyzed for amino acids with simultaneous measurement of the radioactivity of the eluate from the analytical column show...

Tactile roughness of grooved surfaces: A model and the effect of friction
Previous experimental data on the roughness of grooved aluminum tiles provide a data base against which to test theories of roughness perception. A model based on the static deformation of the skin touching th...

Stochastic processes in reversing figure perception
The timing patterns of figural reversals were measured, using a stimulus figure usually seen in one of two well-defined forms. The figure was a three-dimensional surface formed by denting a flat piece of Plast...

Fingertip force, surface geometry, and the perception of roughness by active touch
Ss made magnitude estimates of the perceived roughness of grooved metal plates under conditions of active touch with controlled finger force. The wider the grooves in the plate, the narrower the lands between ...

Contrast reversal or distance paradox in the temperature perception aftereffect?
Data claiming to show a reversal of the classical contrast effect in temperature perception seem instead to bring the temperature aftereffect into the class of aftereffects which show a “distance paradox.” The...

Perception of interpolated position and orientation by vision and active touch
Vision and active touch lead to similar patterns of constant error for the perception of interpolated position in twodimensional and one-dimensional regions, though the errors for touch are larger than those f...

Attention and multidimensional discrimination1
Observers’ ability to perform several discrimination tasks at the same time was tested using a two-alternative temporal forced-choice procedure. Discrimination of two auditory dimensions (pitch and intensity) ...

The effect of the square root of time on continuing perceptual tasks
When an observer is confronted with a stimulus pattern that in some aspect does not change over time, perception of that aspect of the pattern does change. This paper documents several different types of chang...
