Transcribed Image Text:8.67 Free recall memory strategy. Psychologists who study
①memory often use a measure of "free recall" (e.g., the
RECALL number of correctly recalled items in a list of to-be-
remembered items). The strategy used to memorize the
list-for example, category clustering-is often just as
important. Researchers at Central Michigan University
developed an algorithm for computing measures of cat-
egory clustering in Advances in Cognitive Psychology
(Oct. 2012). One measure, called ratio of repetition, was
recorded for a sample of 8 participants in a memory study.
These ratios are listed in the table. Test the theory that the
average ratio of repetition for all participants in a similar
memory study differs from .5. Select an appropriate Type
I error rate for your test.
.25 .43 .57 .38 .38 .60

The pictures were presented in a random order to eight 4-year-olds and eight 5-year-olds, who were asked to memorize the pictures. The researchers used the order in which the pictures were recalled to obtain a clustering score for each child. A score of 1 meant that the pictures were not clustered by category at all during recall; whereas a score of 10 reflected perfect clustering of objects during recall (for example, all foods recalled first, then all animals, then all toys, etc.). Using alpha = .05, determine whether or not the children of different age groups differed in terms of clustering in memory.

- A researcher conducts an experiment to test whether memory changes with age. They recruited 24 participants separated into four age groups. The groups differ according to the age of subjects. In group one, all participants are 30 years old. Group 2, 40 years old. Group 3, 50 years old. And group 4, 60 years old. Assume that the participants are all in good health and that the groups are matched on other important variables such as years of education, IQ, gender, motivation, and so on. Each participant is shown a series of nonsense syllables ( a meaningless combination of three letters such as Daf or FUM ) at a rate of one syllable every four seconds. The series is shown twice, after which participants are asked to write down as many of the syllables as they can remember. Below is number of syllables remembered by each participant. 30 years old 14 13 15 17 12 10 40 years old 12 15 16 11 12 18 50 years old 17 14 14 9 13 15 60 years old 13 10 7 8 6 9 what is the alternative and null…arrow_forwardA researcher is interested in the relationship between birth order and personality.
