Some assembly required: building a hands-on model of a single receptive field in the retina.

Many students struggle to understand the sometimes counterintuitive and complicated organization of the retina. As soon as they begin to grasp these complex relationships, we add another confusing concept: the organization of receptive fields of individual ganglion cells. Publishers provide figures in textbooks and videos, but like many topics in physiology, students may learn more effectively using hands-on models.

A relational structure of voluntary visual-attention abilities.

Many studies have examined attention mechanisms involved in specific behavioral tasks (e.g., search, tracking, distractor inhibition).

P300-based Stroop study with low probability and target Stroop oddballs: the evidence still favors the response selection hypothesis.

This paper addresses the issue of the locus of action in cognitive processing during Stroop effects. It uses the P300 latency to assess stimulus processing effects, but, for the first time, under conditions in which Stroop stimuli are rare and target stimuli. The study was also concerned with demonstrating that apparent P300s during verbal responding are in fact uninterpretable due to contamination of EEG by speech-related artifact.
