Developing Definitions for Concepts • Concepts (hypothetical constructs): things for which direct observations can’t be made • Definitions move us from abstract to concrete • Love and Interpersonal attraction • Definitions are statements asserting that one term may be substituted for another • Tell us what concepts and variables really mean • Isolate essential qualities of concepts
Diagnostic Questions for Conceptual & Operational Definitions • What do you mean by? Conceptual • How will you measure? • How will you make observations? • What will you do to detect the presence of your variable in the setting you are studying? Operational

Assessment • An hypothesis that states simply that there will be some kind of relationship between variables, or some difference between groups of the IV, without stating the direction is called. . . • ANSWER: non-directional hypothesis • ANSWER: also referred to as “two-tailed”
Assessment • Independent variables may be related to dependent variables in 3 ways. What are they? • ANSWER: 1) Positive2) Negative3) No relationship
Assessment • What’s the IV/DV in the following: There is a positive relationship between perceived realism and Reality Television Affinity. ANSWER: 1. IV = Perceived Realism2. DV = Affinity Toward Reality TV
Assessment • Is this an H, or RQ? There is a positive relationship between Perceived Realism and Reality Television Affinity. ANSWER: Directional hypotheses
Assessment • What does “positive” relationship mean in his H? There is a positive relationship between Perceived Realism and Reality Television Affinity. ANSWER: Increases in the IV are associated with increases in the DV – so, as PR increases, so with one’s “liking of”, or affinity toward, RTV
Assessment • Name at least 3 sources in which you might find conceptual definitions of variables in your RQ or H ANSWER: • 1. Journal articles (Conceptual Lit. Reviews) • 2. Specialized Encyclopedias/Dictionaries • 3. Textbooks • 4. Handbooks, Yearbooks, Annual Reviews

FOUNDATIONAL Necessary to later operationalize and measure if it exists CONCEPTUAL FIT Preserve meaning between conceptual and operational SOURCES Journal articles, Dictionaries, Textbooks, Conceptual Lit. Reviews, FORMS PROBLEMS measured, direct classification (via observation) Too....much, little, vague, circular, value-laded, etc. (pp. 102-104)

How do we operationalize “intimate relationships?” Scores on a relational intimacy scale (from 1-7) Examples - Definitions How is social support expressed between members of intimate relationships? - Expression of social support = communication that reduces uncertainty about self and the other - Intimate relationships = degree of emotional attachment There is a positive relationship between self-disclosure and interpersonal attraction? How do we operationalize community?
