Preface – Interpersonal Communication

Foundations of Interpersonal Communication

Interpersonal communication involves messages sent and received between two people. It occurs across a wide variety of relational contexts, including spouses, dating partners, coworkers, physicians, therapists, and strangers.

Key Human Needs in Communication

William Schutz proposed three primary needs that drive interpersonal communication in the Fundamental Interpersonal Relations Orientations Theory: control, inclusion, and affection.

Control

Control refers to an individual's ability to influence another person's behavior or ideas because it is perceived as the right thing to do. Control is distinct from manipulation, which is defined as influencing another person's behavior or ideas to one's own advantage through dishonest, unscrupulous, and insidious means. Control itself is an inherently neutral construct.

Inclusion

Inclusion is the innate human desire to belong to groups and social communities. This need originates at birth within families and continues throughout life through participation in sports teams, social organizations like fraternities or sororities, workplaces, and professional associations.

Affection

Affection originates from the Latin term affectio, which refers to emotions or feelings. Kory Floyd and Mark T. Morman defined affection as an emotional state of fondness and positive regard toward a specific target. Humans have an innate need to both express and receive affection across relationships with parents, coworkers, friends, siblings, and children.

Ethical Communication

Communication strategies function as tools that can either enhance or destroy lives. A kind word and smile can make someone's day, whereas an evil glare and cutting remark can destroy it. Ethical communication requires awareness of how individual expressions impact others.

Statistical Relationships in Research

Social scientific research in interpersonal communication relies heavily on statistics, focusing primarily on relationships and differences.

A variable is anything that can vary from person to person, such as height, weight, public speaking anxiety, or relationship satisfaction. Examining a statistical relationship requires obtaining scores on two separate variables for a single individual. In research conducted by Melissa Wanzer and Melanie Booth-Butterfield examining humor orientation (HO)—the use of jokes and joking during interactions—researchers evaluated self-reported HO and other-reported HO using Steven Booth-Butterfield's scale.

Positive Relationship

In a positive relationship, as scores on one measure increase, scores on the second measure also increase; as scores on one decrease, scores on the other decrease. Research shows a positive relationship between a person's perception of another's humor orientation (other-reported HO) and their perceived popularity or social attractiveness.

Negative Relationship

In a negative relationship, as scores on one variable increase, scores on the second variable decrease. Wanzer and Booth-Butterfield identified a negative relationship where higher scores on self-reported HO correlated with lower scores on reported loneliness.

No Relationship

No relationship indicates that changes in scores on one measure do not produce changes in the scores of another measure. Wanzer and Booth-Butterfield found no relationship between self-reported HO and another person's perception of social attractiveness.

Correlation vs. Causation

Correlations measure statistical relationships between variables but cannot establish causality. A correlation does not prove that variable $X$ caused variable $Y$.

Types of Differences in Social Sciences

Researchers analyze two distinct categories of differences: differences of kind and differences of degree.

Differences of Kind

Differences of kind exist when individuals fall into specific categories with distinct prescribed behavioral patterns, such as the contrasting behaviors exhibited during games by cheerleaders compared to football players.

Differences of Degree

Differences of degree compare scores of two or more groups on a single outcome variable. Max Roser, Cameron Appel, and Hannah Ritchie examined human height data from 1896 to 1996 and found that males consistently averaged $171\,cm$ while females averaged $159\,cm$. Differences of degree focus on group averages rather than individual extremes.
