Comparison of sensitivity of psychophysical and electrophysiological measures of scotopic thresholds in the vicinity of the blind spot

A section of the blind spot was mapped by obtaining detection and averaged EEG threshold measurements using three stimulus light intensities. It was found that averaged EEG and detection measures of the blind spot were equally sensitive when the two highest stimulus intensities were used, although more observations of the stimulus were required with averaged EEG. Detection thresholds were superior to averaged EEG measures with the dimmest stimulus.

     

Questioning and Creating: A Model for Curriculum Reform

ABSTRACT Creativity research has unsettled education by newly defining neglected abilities, and by proposing new methods like training in questioning abilities, but conventional methods do not encourage students to learn or think by asking good questions. We need to cultivate the full spectrum of talents by bridging the research—classroom practice gap. A proposed three-dimensional model for analyzing curricula, courses, and classes would show us where we are not doing a good job in teaching students to think while we are simultaneously teaching them subject-matter content. Content is best learned as a by-product of thinking or learning processes. The proposed model capitalizes on transfer effects of both processes and content, and may be of value in working, not only with those highest in a talent, but also with the educationally deprived. Every student should learn to use each of his abilities at some point in the educational process, but different teachers may specialize in various contents, processes, or methods.     

Sequential response effects in the white rat during conditioning and extinction on a DRL schedule,

Sequential IRT data were obtained for three rats on a DRL 60-sec reinforcement schedule. It was found that first-order sequential dependencies exist under this schedule, including the partial dependence of the length of any given IRT on the length of the preceding IRT. The sequential analysis also served to extend the finding in the literature, based on frequency distributions, that the likelihood of a reinforced IRT is greater after a reinforced IRT than a non-reinforced IRT. Rapid extinction and reconditioning were obtained.
