Select two of the following aphorisms: (1) “Birds of a feather flock together”; (2) “Opposites attract”; (3) “The more the merrier”; (4) “Two heads are better than one”; (5) “Two’s company; three’s a crowd.” Translate each aphorism that you select into a testable hypothesis. Provide operational definitions of each of the variables in each hypothesis.
What will be an ideal response?
Ans: The answer should include examples similar to the following:
“Birds of a feather flock together.” Hypothesis: The more similar two people are, the more likely they are to be attracted to each other. Operational definitions: Similarity—(high) correlation between two people's scores on personality and intelligence measures. Interpersonal attraction—attraction ratings completed by the members of the couple; pupil dilation; whether a follow-up phone call takes place.
“Opposites attract.” Hypothesis: The more dissimilar two people are, the more likely they are to be attracted to each other. Operational definitions: Dissimilar—(low or negative) correlation between two people's scores on personality and intelligence measures. Interpersonal attraction—attraction ratings completed by the members of the couple; pupil dilation; whether a follow-up phone call takes place.
“The more the merrier.” Hypothesis: As more people participate in a social event, each individual’s enjoyment of the event increases. Operational definitions: More people—the number of people attending an event. Enjoyment—enjoyment ratings; whether a subsequent get-together is endorsed.
“Two heads are better than one.” Hypothesis: Problems are solved more rapidly when two individuals collaborate than when one individual attempts to solve the problems alone.
