Proactive interference in a T maze brightness-discrimination task

Inhibition in Superior Colliculus Neurons in a Brightness Discrimination Task?

Simultaneous recordings were collected from between two and four buildup neurons from the left and right superior colliculi in rhesus monkeys in a simple two-choice brightness discrimination task. The monkeys were required to move their eyes to one of two response targets to indicate their decision. Neurons were identified whose receptive fields were centered on the response targets. The functi...

Verbal and Visual Proactive Interference in Post-Traumatic Stress Disorder

Objective: Working memory executive deficits have a role in maintaining Post-Traumatic Stress Disorder (PTSD) symptoms including flashbacks and reexperiencing. Accordingly, the aim of the present study was to compare the visual and verbal Proactive Interference in trauma-exposed individuals with and without PTSD.  Method: In this retrospective study, we recruited subjects through the purposiv...

Anoxia and Brightness Discrimination

1. Brightness discrimination has been studied with individuals breathing oxygen concentrations corresponding to 7 altitudes between sea level and 17,000 feet. The brightnesses were 0.1, 0.01, and 0.001 millilambert involving only daylight (cone) vision. 2. At these light intensities, brightness discrimination begins to deteriorate at fairly low altitudes. The deterioration is obvious at 8,000 f...

Proactive and coactive interference in age-related performance in a recognition-based operation span task.

BACKGROUND Generally, older adults perform worse than younger adults in complex working memory span tasks. So far, it is unclear which processes mainly contribute to age-related differences in working memory span. OBJECTIVE The aim of the present study was to investigate age effects and the roles of proactive and coactive interference in a recognition-based version of the operation span task....
