Psychology Research Methods / Stats - Analyze the Data

2. Pigeons were trained to peck to obtain food. During extinction, one group of 21 pigeons was given a drug that inhibits the protein metabolism necessary for memory, while another group of 21 pigeons was not. The rate of pecking was then analyzed (use a one-tailed test). Does the drug increase the pigeons' pecking behaviour? (a) What test would be used to analyze these data? (b) What is the Ho? (c) What is the H1? (d) How many df are there in total? (e) Given *=0.05, what is the critical value of t? (use a one tailed test) (f) Would an obtained value of t of 1.62 lie within the rejection region? (g) Does the treated group peck at a significantly higher rate (given t = 1.62)? (... click for more

different perspectives of early psychology

1. Compare and contrast three different perspectives of early psychology. 2. Early behavioral psychologists demonstrated it is easier to modify behavior when the expected behavior is rewarded. For example, you compliment your child for doing well in school, or you get coupons for your next purchase because you spent so much at the grocery store. 1) Explain the benefits of using this type of behavior modification correctly. 2) Also explain some negative affects that can occur if the wrong behaviors are rewarded.

the benifits of behavorial modification and the different perceptions of senses

Total lenght- about 3 to 4 paragraphs 2) I need an elaboration of a specific example of a sense and description of how it can be precieved in different ways. I need help explaining the sensory systems involved from begining to end. Total length - about 3-4 paragraphs
