● Systematic observation of hypothesized connections Paradigmatic assumptions ○ World view: guide how we make decisions and carry out research ○ A set of assumptions that interpret our world ○ Comes from the culture you were raised in or exposed to in terms of how you see relationship b/w individuals or how you see your role in life or whatnot ■ In research, its a set of assumptions/worldview that you have ■ You often won’t realize you have this until you explore and think why do you think the way that you do? ○ Assumptions in different areas ○ Compared on 3 paradigmatic assumptions ■ 1- ontology: view of reality ● What exists? [what is?] ■ 2- epistemology: knowledge and justification ● How do I know? ■ 3- axiology: values and ethics ● What is valuable? [what should be?] ○ Methodology: research process ^unpacking those 3 paradigmatic assumptions 1- ONTOLOGY: world view of reality; what exists? ○ Qualitative approach: ■ There is no “real” world external to individuals ○ Quantitative approach: ■ There is a “real” world external to the individual that exists 2- EPISTEMOLOGY: knowledge and justification; how do i know? ○ Qualitative approach: ■ Communication understood only from the perspective of the individuals communicating ■ No search for underlying regularities ○ Quantitative approach: ■ Attempts to explain and predict patterns of communication ■ Looks for regularities/patterns and causal relationship 3- AXIOLOGY: ethics and value; what is valuable? ○ Qualitative approach ■ Research is shaped by values (personal values) ○ Quantitative approach ■ Research should be value-free (no judgments/assertions of right/wrong or good/bad) “Positive change following trauma and adversity; a review” METHODOLOGY: method of inquiry ○ Qualitative approach ■ First-hand knowledge must be obtained; analysis of subjective accounts ■ Non-numerical ■ Ethnography participant observation focus groups

Quantitative approach ■ Systematic protocol and scientific rigor ■ Numerical ■ Content analysis survey experiment QUANTITATIVE METHODS ○ Any approach that uses systematic observations to account for and generalize about human behavior ■ Systematic: when something is systematic it repeats itself; element of repetition ● Intentional; focuses, not haphazard ● Replicable; replicate to rule out “chance” ● Valid: measuring what you say you are measuring ■ Account for: ● Count and quantify ■ Generalize: ● draw inferences about larger group/population RESEARCH DESIGNS: QUANTITATIVE ○ CONTENT ANALYSIS ■ Research technique for the objective, systematic, and quantitative description of manifest content of communication ○ SURVEY ■ Involving the administration of questionnaires or interviews to relatively large groups of people ○ EXPERIMENTS ■ Research involving manipulation of the independent variables and researcher control over the events to which research participants are exposed Scientific inquiry ○ Description (what is) ■ Look for social regularities (ie. patterns) ■ Descriptive research - research intended to describe and organize social phenomena ○ Explanation (why it is) ■ Develop understanding of why pattern exists ■ Active form of observation ■ Explanatory research - research designed to test relationships (ie. hypotheses; cause-and-effect) ○ Prediction (what will be) ■ The better your explanation, the better your ability to predict ○ Control (what should be) ■ Prediction allows for control of conditions/situations The wheel of science ○ —> Theory —> hypotheses —> observation —> empirical generalizations —> ○ Up the sides ○

○ ^induction ○ v deduction Model of communication research ○ Research design ■ Phase 1: conceptualization ■ Phase 2: planning and designing research ■ Phase 3: methodologies for conducting research ○ ■ Phase 4: dara collection ■ Phase 5: analyzing and interpreting data ■ Phase 6: re-conceptualization Origins of research topics ○ How do researchers pick a topic? ■ Study state of scientific discipline (follow-up answered Qs) ■ Social problem ■ Social premiums (hot topics get funding) ■ Personal experience (group memberships, daily observations) ■ Practical considerations (e.g., space, time, or money) ○ Overarching question or statement of the problem ■ What is it that you want to know? CONCEPTUALIZATION ○ Concept: an idea about, or label placed on, a phenomenon ■ General or abstract mental images ○ Conceptual definition: describes what a concept means by relating it to other abstract concepts. ■ “Dictionary definition” ROLE OF THEORY ○ Theory: an attempt to explain some aspect of social life; framework for understanding a phenomenon Examples: ○ For the following concept, give a: conceptual definition (what concept means to you?): ■ “Creepiness” ● Research study on the nature of creepiness

Research group: Sophia, Olivia, Suz, Claire, (Jill?) ● Who is behind a post and does that matter? ● Credibility? ● Influencers ● Intersection between gender and social media influencing ● Instagram * ○ Completely different literature/theories/hypthosis ○ Number of likes, followers, posts

Hypothesis: ○ The higher A is, the higher or lower B is ○ 1- Have a lot of posts and classify them - content analysis ○ 2- Experiment —> whether or not you would purchase this ■ Manipulate ■ EXPERIMENTS ● Research involving manipulation of the independent variables and researcher control over the events to which research participants are exposed ■ If ads influence their desire to buy something ■ Two screenshots - 1 has 40k one has 3k ● People find the more followers more convincing ● # of followers is a positive predictor of the likelihood of a follower to buy sponsored content ■ Most practical - need a control ● Need to assume some people know this person and they have reputations —> not controllable ■ No way clicking on # of followers to actually check

Lecture 2: 8/27/18 Model of Communication Research ● Conceptualization ○ Form an idea about what needs to be studied ● Planning and designing reserarch ● Methodologies for conducting research ● Data collection ● Analyzing and interpreting data ● (Missed last phase)** Role of Theory ● Theory: a logically interconnected set of propositions that show how or why a relationship occurs ○ Framework for understanding phenomenon ○ Includes a set of concepts and their relationships ● Examples: ○ 1- Research content analysis article looking at hypersexuality of females in video games ■ Abstract (summary) they tell you they’re using social cognitive theory as a theoretical anchor ■ “SCT provides a theoretical grounding to understand how game players may learn…” ○ 2- Uncertainty reduction theory ■ Information seeking beyond initial reaction (negotiating relational uncertainty within close relationships)

A theory is a good starting pt for understanding how a specific concept will work ● Theoretical models showing how concepts are linked to each other ○ Those links are easy, testable statements you can look at

PHASE 1 - Conceptualization: ● Concept = an idea about, or label placed on, a phenomenon. General or abstract mental images ○ Think of them in terms of a conceptual definition: describes what a concept means by relating it to other abstract concepts ■ “Dictionary” definition ■ Define what you mean by a concept **** —> good research articles do this ● Example: ○ For the following concept, give a: ■ Conceptual definition (i.e. what concept means to you?) ■ “Obsessive Relational Intrusion” ● Obsessive - frequent or recurring pattern ■ “Repeated and unwanted pursuit and invasion of one’s sense of physical or symbolic privacy by another person, either stranger or acquaintance, who desires and/or presumes an intimate relationship” ● It is, in short, a form of ongoing and unwanted pursuit of a relationship PHASE 2: Operationalization: ● Operational definition: describes a concept in terms of its observable and measurable characteristics or behaviors ○ Specification of observable characteristics of a concept ● Variables: measurable characteristics of concepts ○ Variable is any concept that can have two or more values/properties to it ○ Attempt to categorize a concept —> measure it ● Variables have different types ○ (levels) / amounts (quantities) ■ Honda: Accord, Civic, Prelude ○ Categories of a variable = attributes ○ example: ■ Concept = cisgender ■ Variables = biological sex, gender identity ■ Attributes = male, female … etc. VARIABLES CONT’D ● Main types of variables ○ Independent variable (IV) ■ Variable thought to influence changes in another variable

■ Also known as input variable; predictor variable Dependent variable (DV) ■ Thought to be changed by the independent variable ■ The effect/consequence of something ■ Aka: outcome variable, criterion variable others: ○ Moderating variable ■ Affects the direction and/or the strength of the relationship between an IV and a DV ● Either strengthens or weakens the nature of the relationship ■ Influences the strength of the relationship between the IV and the DV ■ The IV and DV have a relationship but this other thing (mod variable) can intensify or weaken the relationship ■ **special type of Independent Variable** ■ Example: ● Media violence (IV) effect on aggressive behavior (DV) ○ Moderating variable is “Aggressiveness of viewer” ○ Mediating variable ■ Intervening variables ■ It explains the relationship between the IV and DV ■ Mediates to the extent that it accounts for the relationship between the predictor and criterion ● Explains the relationship between IV and DV ● Without the mediator variable, there is no relationship ■ Example: ● Exposure to alcohol ads —A> growth of alcohol use —B> problems due to alcohol use ● Mediating variable (in the middle of arrow A): liking of alcohol ads ○ Control variable ■ Held constant, or prevented from varying, during the course of observation and analysis ■ Any other variable that may affect the outcome ● Variables can be controlled in research design and data analysis ● Example: control for age, gender, ethnicity Research is about making connections between variables Examples: ○ 1- What is the effect of physical attractiveness on impressions of friendliness? ■ IV = physical attractiveness ■ DV = impressions of friendliness ○ 2- do men and women have different views about abortion? ■ IV = sex (levels of IV: men, women) ■ DV = views about abortion ○

Types of Relationships ● Three main types (Research tells you what kind of relationship the variables have) ○ 1- Positive (direct) relationship ■ As X increases, Y increases: X decreases, Y decreases ■ (^^) or (vv) ○ 2- Negative (inverse) relationship ■ As X increases, Y decreases: X decreases, Y increases ■ (^v) or (v^) ○ 3- Curvilinear relationship: ■ a relationship that changes over the course of the two variables, either becoming positive (when negative) or negative (when positive) ■ Two types: ● Inverted U shaped curvilinear relationship ● U-shaped curvilinear relationship ■ Suggests that it looks like there might be a direct/inverse relationship but at a certain point, that starts to change and it goes the opposite direction ■ Ex: performance vs. amount of anxiety ● Too little anxiety, problematic (won’t perform well) ● An optimal amt of anxiety (highest performance) ● Too much anxiety (won’t perform well) ○ Inverted U shape 8/29/18 - Lecture ●

Announcements ○ Week 2: all members read suggested articles; locate other relevant articles based on interest ■ Read articles in detail to determine how variables of interest are connected; draw model; develop testable hypothesis/research questions ○ Week 3: write literature review (BM #1) ■ Benchmark 1 - Wed. September 12th by Midnight ■ Exam 1 - Mon Sept. 17th

(Cont’d aug 29) ●

Hypothesis: a tentative (testable) statement about the relationship between the independent variable and dependent variables ○ Hypothesis posed when: ■ Theoretical support (propositions or assertions) about relationship ■ Existing (significant) empirical evidence supporting connections ○ Hypothesis of association: predicts a relationship ■ Ex: there is a relationship between high school GPA and SAT scores ○ Hypothesis of difference: predicts a difference ■ Ex: men and women differ in amount of self-disclosure

11



Hypothesis Cont’d ○ 1- Directional Hypothesis ■ Predict direction of relationship/difference (e.g., A & B positively related; males more than females) ■ One-tailed hypothesis ○ 2- Non-directional hypothesis ■ Does NOT predict direction of relationship/difference (e.g., A & B related; sex differences) ■ Two-tailed hypothesis

(missed two slides) ● Research Questions ○ A question posed about ‘relationships’ between variables ○ Within study, use RQ when… ■ When there is not theory or previous research ■ No clear research results from which to predict; conflicting findings ■ Usually occur when there is controversy ● Inconclusive results or no evidence to base anything on ● **probably won’t use one for our project** ○ Sample research question: ■ Do men and women differ in amount of self disclosure? ***(Writing Testable Hypothesis and Research Questions) —> Supplemental website on BB for handout that teaches you how to write testable hypotheses and research questions ***



Never want to write a hypothesis when you say “music will affect mood” ○ Problem: too general ■ Mood has many subcontexts ■ Anytime you’re dealing with emotions or mood is not substantial enough

LECTURE 3: MEASUREMENT ● Class Outline ○ Types of measurement ■ Self-report, behavioral, etc. ■ Measurement Index vs. Scale ○ Levels of Measurement (N.O.I.R.) ■ Nominal, Ordinal, Interval, Ratio ● Operationalization ○ Conceptual definition: describes what a concept means by relating it to other abstract concepts ■ Dictionary definition ○ Operational definition: describes a concept in terms of its observable and measurable characteristics or behaviors ■ Allow us to specify observable characteristics of a concept

12



Measurement ○ Measurement allows us to record and order in a systematic way observations of those ‘behavioral’ characteristics ○ EXAMPLE ■ Give an: Operational definition (i.e. what is a way you could measure that meaning in a study?) based on a given conceptual definition. ■ Come up with specific ways to measure (e.g., questions, behavior) ■ “Love” ● Level of attachment/feelings/thoughts about someone or something ■ Conceptual definition: a combination of affection/intimacy that may escalate depending on nature of the relationship ● Mutual connection measured by affection in verbal and nonverbal ways ○ Types of Measurement: ■ 1 Physiological measure ● Physical changes (heart rate, blood pressure, stress hormones) ● Advantageous if you’re interested in how the biological system works ○ Often is limited in resources and is very expensive ○ Health comm scholars ...
