a) Compute the least Squares regression line for predicting auditory response time from visual response time.

b) Construct a 95% confidence interval for the slope

c) Can you conclude that visual response is useful in predicting auditory response? Use alpha=.01 in hypothesis test

d) create a labeled scatter plot of the data

Interpretation:

The scatter plot delineates the strong positive linear relationship between the quantitative variables Visual (X) and Auditory (Y). The direction of the data points is upwards. Hence, we can say that there exists a positive linear relationship between the variables.

A researcher hypothesizes that reaction time (RT) measured in milliseconds in response to a startling stimulus will be lower (faster) before people drink 5 beers than it will be afterward. A sample of 12 patients is presented with a startling stimulus, and their mean score is 6.08 milliseconds with an SD of 1.38. They drink 5 beers, another startling stimulus is presented, and participants’ mean reaction time is 14.25 milliseconds with an SD of 3.7. The raw scores and Z-scores...

Reaction time studies are studies in which participants receive a stimulus and the amount of time it takes for them to react is measured. In one simple type of reaction time study, each participant holds a clicker button and stares at a screen. When the participant sees a part of the screen light up, he or she clicks the button as quickly as possible. The researcher then records how much time elapsed between when the screen lit up and when...

"When a visual stimulus is presented to us, our visual brain regions show two kinds of electrophysiological signals. One is fast and comes very soon (<100 ms) after the stimulus is shown, and can be traced to be coming from the retina through the thalamus. The other signal is slow and comes a bit later (>300 ms) after the stimulus, and can be traced to be coming from frontal and parietal regions. Disrupting these later signals that come from frontal...

The driver's reaction time in response to a particular potential traffic hazard is the time required from the point of initial detection of the hazard in one’s field of view to the time that vehicle control components are actuated (such as movement of one’s foot to the brake pedal). The following data represents the measurements of the driver’s reaction time in seconds for the male and female participants of the experiment: 0.50 0.49 0.49 0.54 0.44 0.49 0.51 0.46 0.51...

Define neutral stimulus (NS), Unconditioned Stimulus (US or UCS), Unconditioned Response (UR or UCR), Conditioned Stimulus (CS), and Conditioned Response (CR). What is an organism learning when they’ve been classically conditioned? What is the evidence that that association has been learned? How do contiguity, contingency, stimulus value, novelty, and biological preparedness influence conditioning processes?
