Textbook Question

Chapter 15.4, Problem 31E

The following graphs appear in the paper “Which Thoughts Count? Algorithms for Evaluating Satisfaction in Relationships” (Psychological Science [2008]: 1030–1036). The vertical axis in both graphs represents mean score on a measure or relationship satisfaction.

Chapter 15.4, Problem 31E, The following graphs appear in the paper Which Thoughts Count? Algorithms for Evaluating , example 1

Chapter 15.4, Problem 31E, The following graphs appear in the paper Which Thoughts Count? Algorithms for Evaluating , example 2

a. In the first graph, mean relationship satisfaction is plotted for each level of a measure of thoughts of passion (on the horizontal axis with levels low positive, average, and high positive) separately for participants with low, average, and high approach goals.

Does this graph suggest an interaction between the two factors, thoughts of passion and approach goal level? What aspects of the graph support your response?

b. In the second graph, mean relationship satisfaction is plotted for each level of a measure of thoughts of insecurity (the horizontal axis with levels low negative, average, and high negative) separately for participants with low, average, and high avoidance goals.

Does this graph suggest an interaction between the two factors, thoughts of insecurity and avoidance goal level? What aspects of the graph support your response?

c. Consider the following quote from the paper: In short, the amount that increases in positive and negative thoughts about the relationship contributed to overall feelings of satisfaction differed in accordance with an individual’s social goals, such that positive thoughts were meaningful to participants high on approach, and negative thoughts were meaningful to those high on avoidance.

Do the given graphs support this statement? Explain.

Definition Definition Measure of central tendency that is the average of a given data set. The mean value is evaluated as the quotient of the sum of all observations by the sample size. The mean, in contrast to a median, is affected by extreme values. Very large or very small values can distract the mean from the center of the data. Arithmetic mean: The most common type of mean is the arithmetic mean. It is evaluated using the formula: μ = 1 N ∑ i = 1 N x i Other types of means are the geometric mean, logarithmic mean, and harmonic mean. Geometric mean: The nth root of the product of n observations from a data set is defined as the geometric mean of the set: G = x 1 x 2 ... x n n Logarithmic mean: The difference of the natural logarithms of the two numbers, divided by the difference between the numbers is the logarithmic mean of the two numbers. The logarithmic mean is used particularly in heat transfer and mass transfer. ln x 2 − ln x 1 x 2 − x 1 Harmonic mean: The inverse of the arithmetic mean of the inverses of all the numbers in a data set is the harmonic mean of the data. 1 1 x 1 + 1 x 2 + ...
