Two experimenters will read prepared lists of words aloud. After each list is read, participants will immediately write down as many words as they can remember on for 1 minute each. When all of the lists are completed, participants will be given a recognition test, which contains studied and non-studied items. For each item, the students will rate whether it was a) surely new, b) probably new, c) probably old, or d) surely old. If the item was rated as surely old, participants should indicate which of the two experimenters they remembered uttered the word. Answer the following questions. a. Identify the independent variable and the levels of the independent variable.  b. Identify the dependent variable. c. Outline your theory of memory. d. What is the experimental hypothesis?

Question

Two experimenters will read prepared lists of words aloud. After each list is read, participants will immediately write down as many words as they can remember on for 1 minute each. When all of the lists are completed, participants will be given a recognition test, which contains studied and non-studied items. For each item, the students will rate whether it was a) surely new, b) probably new, c) probably old, or d) surely old. If the item was rated as surely old, participants should indicate which of the two experimenters they remembered uttered the word.

Answer the following questions.
a. Identify the independent variable and the levels of the independent variable. 
b. Identify the dependent variable.
c. Outline your theory of memory.
d. What is the experimental hypothesis?

Follow-up Question

Use the attached picture to answer the following questions:

a. With regard to the critical lures, what percentage of the critical lures were
classified as “surely old”?

b. What percentage of the participants said the critical lures were “surely
old”?

c. What percentage of the participants that classified a critical lure as ‘surely
old’ indicated they remembered which experimenter had uttered the critical lure (a word never actually presented)?

d. Do the results support the experimental hypothesis? Be sure to provide an explanation by referring to the results.

Note. The values represent the percentage of targets placed into each of the recognition
categories.
Table 1 shows the four levels of item status when it comes to word recognition in relation to the
four possible responses that correspond to the item status's.

Follow-up Question

Dermine whether the interaction between type of word and classification category is statistically significant. Describe the findings using APA style. Use the p-value to assess statistical significance. Recall, if p-value ≤ α, reject H0 (result is statistically significant.)
