A Lexical-Scale Approach to Predicting Behavior Using the
Inventory of Individual Differences in the Lexicon (IIDL) Nicolas A. Brown, Ryne A. Sherman, & David Serfass Florida Atlantic University
Overview
Method
Results
Measures
Inventory of the Individual Differences in the Lexicon (IIDL; Wood, Nye, & Saucier, 2010)
61 pairs of synonyms
Items include, “outgoing, sociable; creative, imaginable”
Procedure
Participants were invited to complete the study in exchange for partial course credit.
Participants completed the IIDL and were video recorded during an introductory interview completed as part of another study.
Four trained research assistants used the RBQ to code participant’s behavior during the interview.
Average profile r = .36, average alpha = .70 Ex
The current study examines whether a newer lexical measure of personality, the Inventory of Individual Differences in the Lexicon (IIDL) can be used to predict individual behavior.
Personality psychology has relied on well-studied measures of individual differences such as the Big Five (Costa & McCrae, 1992) and the California Adult Q-set (Block, 1961) to describe individuals and predict behavior.
Newer scales such as the Inventory of Individual Differences in the Lexicon (IIDL; Wood, Nye, & Saucier, 2010) have since been developed and used.
Unlike these older measures, the IIDL has not been used to predict individual behavior

Results
Goals of Present Study
Can the IIDL be used to predict individual behavior?
If yes, in what ways does the IIDL relate to behavior?
Goals of the Present Study
Neuroticism
Participants
60 individuals were recruited from Florida Atlantic University’s Human Subjects Pool.
Gender: 55% female, 43% male, 2% did not indicate
Age: M = (SD = 4.39)
Ethnicity: 43% Caucasian, 3% Asian, 20% African-American, 18% Hispanic/Latino, 15% Other
Measures
Riverside Behavioral Q-sort Version 2.0 (RBQ; Funder, Furr, & Colvin, 2000)
67-item measure of observable behavior.
Sample items include, “Exhibits social skills”, “Initiates humor”, “Exhibits awkward interpersonal style”
Method
Discussion
The IIDL appears to be an adequate measure for predicting behavior.
Future studies should investigate the usefulness of single items from the IIDL to predict behavior
