After examining the experimental inventory, think of a personality trait
that you would like to measure using a set of the items from this inventory.
You may choose any trait other than one of the five broad dimensions
of the five-factor model (FFM) or "Big 5": Extraversion, Agreeableness,
Conscientiousness, Emotional Stability, or Intellect/Openness. If you have
trouble thinking of a personality trait that you would like to measure,
you can browse through the personality journals we used in the first lab
exercise and/or talk to other students about ideas. In any case, it may
be useful to talk with others to get their reactions. Keep in mind that
the trait you choose should be one on which you expect to find some individual
differences in a relatively homogeneous group of Penn State psychology
After thinking and talking about personality traits and settling upon one,
write a short paragraph that defines and describes the trait. Put some
thought into this description, for it is the guide for identifying appropriate
scale items. This trait description should be framed in terms of the thoughts,
feelings, and behaviors of persons who are high and/or low on your trait
dimension. See, for example, Snyder's description of a "high self-monitoring
individual" on page 113 of the Briggs and Cheek article.
Identify 24 items from the experimental inventory that you think might
measure the personality trait you have chosen. At least 12 of these items
should follow specific guidelines for item-writing that appear in Wolfe's
(1993) chapter article. To complete your 24-item set, you should also identify
between 1-12 items in accordance with Johnson's (1997) sociolinguistic
model of item responding.
Information to Submit By Email
Send the requested information or answers to the questions to me, email@example.com,
Submit the one-paragraph description of the trait you wish to measure.
List separately the items following Wolfe's guidelines and the items following
Johnson's guidelines. Explain why you think the items in the first set
meet Wolfe's guidelines and why they would assess the trait you are interested
in measuring. Explain what makes the second set of items sociolinguistic
and explain why you think these items would assess the trait you are interested
Describe some hypotheses about the kinds of Life Event and Observer Rating
data that you think your scale might predict. Describe the theory(ies)
underlying your predictions.
Hypothesize how scores on your scale will correlate with the Big 5. From
what theory(ies) did you derive your hypotheses?
