Microanalysis of variable-interval performance during stimulus compounding

Effects of Variable Response-Stimulus Interval (RSI) On Sequence Learning

The objective of this study was to investigate the effects of varying Response-to-Stimulus interval (RSI) on sequence learning by systematically varying it across three different groups (Group1: 0-300ms, Group2: 400-700ms and Group3: 8001100ms) and to assess the implicitness and explicitness of the knowledge acquired through such learning. Serial Reaction time task followed by generation task a...

A Test of Three Models for Stimulus Compounding with Children.

The variable response-stimulus interval effect and sleep deprivation: an unexplored aspect of psychomotor vigilance task performance.

STUDY OBJECTIVES The Psychomotor Vigilance Task (PVT) contains variable response-stimulus intervals (RSI). Our goal is to investigate the effect of RSI on performance to determine whether sleep deprivation affects the ability to attend to events across seconds and whether this effect is independent of impairment in sustaining attention across minutes, as measured by time on task. DESIGN A con...

Polymeric nanocomposites: compounding and performance.

Polymeric nanocomposites (PNC) are binary mixtures of strongly interacting, inorganic platelets dispersed in a polymeric matrix. For full exfoliation, the thermodynamic miscibility is required. There are three basic methods of organically-modified clay dispersion that might result in PNC: (1) in polymer solution (followed by solvent removal), (2) in a monomer (followed by polymerization), and (...

Overexpectation: response loss during sustained stimulus compounding in the rabbit nictitating membrane preparation.

Rabbits were given reinforced training of the nictitating membrane (NM) response using separate conditioned stimuli (CSs), which were a tone, light, and/or tactile vibration. Then, two CSs were compounded and given further pairings with the unconditioned stimulus (US). Evidence of both overexpectation and summation effects appeared. That is, responding to the individual CSs declined despite the...
