Recovery from adaptation as a function of stimulus orientation

Academic Achievement as a Function of Goal Orientation and Course Perception Mediated by Academic Self-Regulation

To help with the prediction of school achievement through a mathematical model incorporating goal orientation, course perception, and academic self-regulation, a sample of 380 9th graders in Tabriz was selected using the cluster sampling method. Instruments used to measure these constructs were translated ones. Data analyses showed that goal orientation and course perception have a direct impac...

Binocular combination of stimulus orientation

When two sine waves that differ slightly in orientation are presented to the two eyes separately, a single cyclopean sine wave is perceived. However, it is unclear how the brain calculates its orientation. Here, we used a signal detection rating method to estimate the perceived orientation when the two eyes were presented with Gabor patches that differed in both orientation and contrast. We fou...

Two-flash thresholds as a function of comparison stimulus duration.

Mediated stimulus equivalence as a function of the number of converging stimulus items.

3 experiments were performed in which the number of stimuli that converged upon a common response in a paired-associate transfer design was varied. 36 Ss served in each experiment. The number of stimuli systematically varied between the 3 studies (20, 10, and 6) while each study utilized 2 responses. Facilitation, interference, and control conditions were set up in each study by varying the sti...

Neural Transplantation as a Strategy for Recovery of CNS Functions

Transplants of neural tissue have been used for nearly 100 years in order to clarify the mechanisms that underlie development and regeneration of the nervous system. With reports from Sweden and Mexico that autografts of adrenal medulla produce at least transient and perhaps dramatic improve­ment in patients severly disabled by Parkinson's disease, the techniques of neural transplantation have ...
