Error Processing In Speeded Response Tasks: Expertise Differences In Cognitive Control, Nicole Bing
Error Processing In Speeded Response Tasks: Expertise Differences In Cognitive Control, Nicole Bing
John Wesley Powell Student Research Conference
In speeded response tasks, the time between external stimuli and the time to react is both minimal and relatively fixed. In accordance with speed-accuracy tradeoff (SAT) theories, reaction time (RT) is often slower after error in order to improve accuracy, which produces post-error slowing. However, in speeded response tasks, typical post-error slowing patterns may not occur. We examined two neural indices of self-regulatory cognitive control, the feedback-related negativity (FRN) and the P300, to identify whether time constraints disrupted the normal processing of performance errors and the refinement of behavior during task execution through cognitive control processes in accord with one’s …
A New Species Of Pristimantis (Amphibia: Anura: Strabomantidae) From Northern Peru, Shenyu Lyu
A New Species Of Pristimantis (Amphibia: Anura: Strabomantidae) From Northern Peru, Shenyu Lyu
John Wesley Powell Student Research Conference
Frogs of the genus Pristimantis are most diverse in northwestern South America. They are distributed from lowland rainforest to elevations of about 4000 m in the Andes. Of the 516 species currently assigned to the genus Pristimantis, 138 species occur in Peru. Herein, we present a new species of Pristimantis from the Cajamarca Region of northern Peru. The new species is known from four male and five female specimens found in high Andean grasslands hiding in the rosette of Puya fastuosa (Bromeliaceae) at 3600 m above sea level. The new species is phenotypically distinguished from its congeners by having …
