When the time between two signals to respond is very short, the response to the second stimulusQuestion 12Answera.slows down.b.remains the same compared to longer intervals.c.speeds up.d.is more accurate.

The slowing of a response to the second of two stimuli presented in quick succession is known asQuestion 11Answera.a Donders C reaction.b.the psychological refractory period.c.a speed-accuracy tradeoff.d.stimulus onset asynchrony.

The brief delay between the presentation of two stimuli is known as theQuestion 1Answera.stimulus onset asynchrony.b.confounding.c.interaction.d.speed accuracy tradeoff.

2. Identify the variation: “For the increase in speed, the time to cover a fixed distance reduces”.

n which of the following situations would we expect the fastest response time?Question 21Answera.The stimulus being presented to the participant is identical in form to the stimulus used as the warning signal.b.The stimulus being presented to the participant is markedly different from the stimulus used as the warning signal.c.The stimulus being presented to the participant is the stimulus the participant was expecting.d.The stimulus being presented to the participant is identical in form to the warning signal but is different from the stimulus the participant was expecting.Clear my choice

A physiologist testing signal transduction rates in two different nerve fibers notices that one fiber conducts signals much faster than the other. Which is the most likely difference between the two?Multiple ChoiceThe faster nerve fiber is myelinated and the slower one is not.The slower nerve fiber is myelinated and the faster one is not.The faster nerve fiber has more dendrites.The faster nerve fiber has more axons.
