Attitudes and Behaviour

People constantly form opinions about the people, places, things, and situations around them, and those opinions shape how they act. This is the domain of social cognition — the study of how people think about others and how those ideas influence behavior. This article covers what an attitude is made of, the functions attitudes serve, how attitudes form through learning, how persuasive information gets processed, and how behavior, personal factors, and environment shape each other over time.

Key Takeaways

• Social cognition is the study of how people think about others and how those thoughts shape behavior; an attitude is a positive or negative feeling towards a person, place, thing, or scenario, made up of affective (emotional), behavioral (action), and cognitive (belief/justification) components.

• Functional Attitudes Theory holds that attitudes serve four functions: knowledge (predicting behavior), ego-expressive (affirming identity), adaptive (gaining social acceptance), and ego-defensive (protecting self-esteem or justifying known-wrong actions).

• Learning Theory explains attitude formation through classical conditioning (paired association), operant conditioning (reward/punishment), and observational learning (watching and replicating others).

• The Elaboration Likelihood Model (Petty and Cacioppo) describes a continuum of persuasive-information processing: central route processing (deep, deliberate thought) versus peripheral route processing (reliance on superficial cues) — most people fall in between, shifting by situation.

• Social Cognitive Theory (Bandura) describes reciprocal determinism: behavior, personal factors, and environment all continuously shape and are shaped by one another, illustrated by how workplace behavior, personal attitudes toward work, and company systems interact and feed back into each other.

Attitudes and Their Components

An attitude is an expression of positive or negative feelings towards a person, place, thing, or scenario. Attitudes develop from experiences with others who affect a person's opinions and behaviors.

Every attitude is made up of three components:

• Affective: the way a person feels towards something — the emotional component of attitude.

• Behavioral: the way a person acts with respect to something.

• Cognitive: the way a person thinks about something — usually the justification for the other two components.

MCAT Callout — Matching a vignette to the right component: if a passage describes someone's emotional reaction, that's the affective component. If it describes what someone actually does, that's the behavioral component. If it describes the reasoning or belief behind the feeling or action, that's the cognitive component. A single attitude can show up in a vignette through any one of these three angles.

Functional Attitudes Theory

Functional Attitudes Theory states that attitudes serve four functions: knowledge, ego expression, adaptation, and ego defense.

• Knowledge function: attitudes provide consistency and stability. Knowing the attitudes of others helps predict their behaviors.

• Ego-expressive function: allows a person to communicate and solidify their self-identity.

• Adaptive function: the idea that a person will be socially accepted if they express socially acceptable attitudes.

• Ego-defensive function: protects a person's self-esteem or justifies actions that are known to be wrong.

MCAT Callout — Ego-expressive vs. ego-defensive: both functions relate to the self, but they work in opposite directions. The ego-expressive function affirms who a person is — it's about identity. The ego-defensive function shields a person from a threat to their self-esteem — it's about protection, sometimes even excusing behavior the person knows is wrong.

Learning Theory

Learning Theory holds that attitudes are developed through different forms of learning. Direct contact with an object can influence attitudes, and direct instruction from others can also shape attitude. Attitudes can also be influenced simply by exposure to other people's attitudes.

Specifically, attitudes may be formed through three learning mechanisms:

• Classical conditioning: an attitude forms through repeated association between a neutral stimulus and one that already triggers an emotional response.

• Operant conditioning: an attitude forms because it was previously rewarded or punished.

• Observational learning: an attitude forms by watching and replicating the attitudes and behaviors of others.

The Elaboration Likelihood Model

The Elaboration Likelihood Model, developed by psychologists Richard Petty and John Cacioppo, separates individuals on a continuum based on how they process persuasive information.

• Central route processing: people who elaborate extensively and think deeply about information, making decisions based on that thought.

• Peripheral route processing: people who do not elaborate and instead focus on superficial details, like a speaker's appearance, a catchy slogan, or a source's perceived credibility.

Most people fall somewhere in the middle of this spectrum, but can lean toward one route or the other depending on the social situation.

MCAT Callout — Central vs. peripheral route processing: this isn't a fixed personality trait — it's situational. The same person might use central route processing when reading a detailed argument they're motivated to evaluate carefully, and peripheral route processing when skimming an ad they don't care much about. Look at how much the person in the vignette is actually engaging with the content of the message, not just their general disposition.

Social Cognitive Theory

Social Cognitive Theory holds that people learn how to behave and shape their attitudes by observing the behaviors of others. Behavior is not learned through simple trial and error — it develops through direct observation and replication of others' actions, in tandem with the influence of personal factors and the environment in which the behavior is observed.

Psychologist Albert Bandura described this three-way relationship as reciprocal determinism: behavior, personal factors (such as thoughts and attitudes), and environment all influence each other.

For example, the work ethic of employees at a company (behavior) is affected by how hard their colleagues work (environment), their previous attitude towards hard work (personal factors), and the systems and infrastructure of the company (environment). In turn, that behavior may create a change in the employees' attitude towards work and in the systems within the company itself — each factor feeding back into the other two.

Why Attitudes and Behaviour Matter for the MCAT

MCAT questions on this material typically describe a scenario and ask you to identify which component or theory is at play:

• Sort a vignette's details into affective, behavioral, or cognitive components before deciding what the question is really testing — many wrong answers confuse a feeling for a belief, or a belief for an action.

• Match a described motivation to the right function of attitude. Wanting to predict someone's behavior points to the knowledge function; expressing identity points to ego-expressive; seeking social acceptance points to adaptive; protecting self-esteem points to ego-defensive.

• Identify which learning mechanism formed an attitude. Reward or punishment signals operant conditioning; repeated pairing with an existing emotional stimulus signals classical conditioning; copying someone else's behavior or attitude signals observational learning.

• Treat central and peripheral route processing as situational, not fixed — a vignette's details about motivation and engagement with a message determine which route is in play, not a stated personality trait.

• Remember reciprocal determinism runs in all directions — behavior, personal factors, and environment each shape and are shaped by the other two, not just environment shaping behavior.

Common MCAT Mistakes

• Confusing the cognitive component with the behavioral component. The cognitive component is the belief or justification behind an attitude, not the action itself — a vignette describing someone's reasoning is testing cognition, even if that reasoning leads to an action described elsewhere.

• Mixing up the ego-expressive and adaptive functions. Ego-expressive is about affirming a person's own identity; adaptive is about fitting in with others' expectations. A person adopting an attitude to gain social approval is demonstrating the adaptive function, not the ego-expressive one.

• Treating central and peripheral route processing as fixed traits. These routes describe how a person is processing a specific piece of persuasive information in a specific moment, not a permanent personality type — the same person can shift routes across different situations.

• Assuming reciprocal determinism only flows one direction. It's a common error to treat environment as only shaping behavior; Bandura's model requires behavior, personal factors, and environment to all influence and be influenced by each other simultaneously.

MCAT-Style Concept Check

Question: A student watches a classmate get praised by a teacher for speaking up in class, and afterward the student starts raising their hand more often, having developed a more positive attitude toward classroom participation. Which mechanism of attitude formation does this best illustrate?

• A) Classical conditioning

• B) Operant conditioning

• C) Observational learning

• D) Central route processing

Answer: C

Explanation: The student did not directly experience the reward — they watched someone else's behavior get reinforced and then adopted a similar attitude and behavior themselves. This is observational learning, not operant conditioning, because the student's own behavior was never directly rewarded or punished. It is not classical conditioning, since no neutral stimulus was paired with an existing emotional response. It is not central route processing, since that concept describes persuasive-message processing, not attitude formation through learning.

FAQ

What is the difference between an attitude's affective, behavioral, and cognitive components?

The affective component is the emotional feeling behind an attitude, the behavioral component is the action taken with respect to it, and the cognitive component is the belief or reasoning that usually justifies the other two.

What are the four functions of attitudes in Functional Attitudes Theory?

Knowledge (predicting others' behavior), ego-expressive (affirming identity), adaptive (gaining social acceptance), and ego-defensive (protecting self-esteem or justifying known-wrong actions).

How is central route processing different from peripheral route processing?

Central route processing involves deep, deliberate engagement with the actual content of a persuasive message, while peripheral route processing relies on superficial cues like appearance, slogans, or credibility. Most people shift between the two depending on the situation, rather than favoring one route permanently.

What is reciprocal determinism?

Reciprocal determinism, described by Albert Bandura as part of Social Cognitive Theory, is the idea that behavior, personal factors (like thoughts and attitudes), and environment all continuously influence and are influenced by one another, rather than one factor simply causing the others.
