Social Psychology Lecture: Introduction and Key Concepts
The Scope of Social Psychology
Social psychology is the scientific study of how the actual, imagined, or implied presence of others influences the thoughts, feelings, and behaviors of individuals. This includes interactions within inner circles, such as family and close friends, as well as formal environments like classrooms.
The presence of others significantly impacts self-perception, emotional responses, and behavioral patterns. Understanding these influences allows individuals to engage in "course correction," aligning their outward portrayal with their internal values and social acceptability.
Key questions addressed in social psychology include:
How are social interactions formed?
How do interpersonal relationships develop?
How does the presence of others influence conformity and obedience?
Social Perception and the Primacy Effect
Social perception refers to how individuals think and feel when meeting others, involving the formation of initial impressions.
The Primacy Effect: This is the phenomenon where the overall impression of another person is influenced more by early information than by later information.
First impressions are formed through "snap judgments" or unconscious assessments.
Once a first impression is formed, it is remarkably durable. Even when contradictory information is presented later, humans tend to hold onto the initial impression.
Expectations formed via the primacy effect dictate what we pay attention to and what we ignore regarding a person's behavior. For example, individuals may ignore toxic traits in long-term friends because of a positive primal impression.
Self-Fulfilling Prophecy: Because we label others based on initial impressions, we come to expect them to act in a certain way. Our treatment of them, based on these expectations, can subsequently cause them to behave in the manner we predicted, reinforcing the original label.
Attributions and Judgment
Attributions are the internal explanations created to assign causes to behaviors witnessed in others or ourselves. There are two primary types:
Situational Attributions: Attributing behavior to an external cause, such as the environment, luck, or the actions of others. For example, blaming a failed test on a room being too hot or a teacher making questions too difficult.
Dispositional Attributions: Attributing behavior to an internal cause, such as personality traits, effort, or personal state. For example, acknowledging a failed test resulted from a lack of studying or high personal stress.
Fundamental Attribution Error: This is a bias occurring when we meet people for the first time or evaluate others. We tend to overemphasize internal (dispositional) factors and underemphasize external (situational) factors. If a classmate is rude, we assume they are generally an unpleasant person rather than considering they might be having a difficult day.
Self-Serving Bias: This is the tendency to attribute our personal successes to internal causes (e.g., "I am smart") while attributing our failures to external causes (e.g., "The test was unfair"). This bias often serves as a self-protection mechanism.
The Dynamics of Attraction
Attraction in psychology refers to a general interest in getting to know someone or being friendly, rather than exclusively romantic interest. Psychologists identify four main factors:
Proximity: Geographic closeness increases the likelihood of friendship. You are more likely to befriend a neighbor than someone living several blocks away.
Mere Exposure Effect: Positive feelings toward a stimulus (including people) increase with repeated exposure. Seeing the same person at a bus stop or in an elevator daily fosters a sense of familiarity and friendly feelings.
Reciprocal Liking: Humans have a natural tendency to like people who demonstrate that they like them. Consistent effort and interest from another person can eventually wear down initial reservations.
Attractiveness and Symmetry: Humans are biologically hardwired to respond to symmetrical faces. Even infants show a preference for faces considered traditionally attractive.
Similarity: There is a strong basis for attraction in shared values, morals, religious beliefs, and political leanings. Similarity in these areas reduces the need for compromise on fundamental morality.
The Matching Hypothesis: This hypothesis suggests that individuals are likely to pair with partners whose social assets and level of physical attractiveness match their own. This is often driven by a fear of rejection from those perceived as significantly more attractive.
Conformity and the Solomon Asch Experiment
Conformity: The act of changing behavior or attitudes to remain consistent with social norms or the expectations of others. It is often described as "falling in line."
Social Norms: These are standard behaviors and attitudes expected of members within a specific group. For instance, the norm for a teacher is to be prepared and fair, while the norm for a student is to participate and submit assignments on time.
The Asch Experiment (): Solomon Asch conducted a famous study on conformity.
The setup involved showing a participant one line and then three comparison lines of varying lengths.
When at least people (accomplices) gave an obviously incorrect answer about which line was the same length, the participant would often doubt their own perception and conform to the group's incorrect answer.
This experiment has been replicated across different age and racial groups with consistent conclusions regarding the pressure to conform.
Obedience and the Milgram Shock Experiment
Obedience: This involves following direct orders from an authority figure. It is a cornerstone of organizations like the military.
Stanley Milgram's Experiment ():
Researchers used a shock machine with increments up to .
The participant (the "teacher") was told the study was about memory and learning. They were instructed to shock a "learner" (an actor) for every wrong answer.
The actor faked pain and distress as the voltage increased.
Despite the apparent suffering of the actor, of participants continued to administer shocks up to the maximum level simply because the authority figure told them the experiment must continue.
This study highlighted the alarming power of authority and how it can lead average people to perform harmful acts.
Group Influence and Performance
Social Facilitation: The effect that the presence of others has on individual performance.
Audience Effects: The impact of passive spectators.
Co-action Effects: The impact of others performing the same task simultaneously.
The Skill Factor: Performance is enhanced on simple or well-learned tasks when others are present. Conversely, performance suffers on difficult or unfamiliar tasks when observed.
Social Loafing: The tendency for individuals to exert less effort when working in a group compared to when they work alone. This occurs because individual responsibility feels diffused. It can be reduced if individual output is monitored or if the group is exceptionally close-knit.
Group Polarization: The tendency for group discussions to shift toward more extreme positions. Individuals with similar views reinforce each other, leading to a radicalization of the group's stance.
Groupthink: A phenomenon where the desire for group cohesion and agreement overrides critical thinking, leading to decisions reached by the group that individuals might not have made alone.
Social Roles and the Stanford Prison Experiment
The Power of Social Roles: Shared expectations about how people in certain positions should behave can drastically alter human behavior.
The Stanford Prison Experiment (): Conducted by Philip Zimbardo.
In the basement of a Stanford University building, a mock prison was constructed.
College students were randomly assigned the roles of either "guard" or "prisoner."
The guards quickly adopted abusive, authoritarian behaviors, including strip searches and psychological harassment. The prisoners became submissive or emotionally distressed.
The experiment, intended to last days, was terminated after only days due to the unethical and inhumane conditions that developed.
The findings demonstrated that individuals can lose their personal identity and moral compass when given a social role with significant power over others.
The Structure of Attitudes
Attitudes are composed of three distinct parts:
Cognitive Component: The thoughts and beliefs one holds about a subject (e.g., "Exercise is good for health").
Emotional (Affective) Component: The feelings or emotions associated with the subject (e.g., "Exercise makes me feel happy").
Behavioral Component: The actions one takes regarding the subject (e.g., "I go to the gym daily").
Cognitive Dissonance
Definition: Cognitive dissonance is an unpleasant state of tension that occurs when there is an incompatibility between one’s beliefs and one’s actions. Humans are biologically driven to reduce this tension.
The Smoking Example:
A smoker knows that "smoking is dangerous" (belief) but continues to smoke (behavior).
To resolve the dissonance, they may:
Change the attitude: "Smoking isn't actually that dangerous."
Reduce importance: "My genes are strong; my relatives lived to be ."
Explain away the inconsistency: "I only smoke when I am stressed" or "I will quit when the kids are older."
Change the behavior: Quit smoking (the most difficult option).
Prejudice and Discrimination
Prejudice: Negative attitudes, beliefs, and emotions directed toward members of a particular group. These can escalate into hatred.
Discrimination: Negative behavior or actions taken against members of a group based on prejudice.
Realistic Conflict Theory: This theory suggests that as competition for limited resources increases, prejudice and discrimination between groups also increase.
In-groups vs. Out-groups:
An In-group is a social group to which one belongs and feels a sense of togetherness (e.g., family, college, nationality). Members tend to protect and favor their in-group.
An Out-group is a group with which one does not identify. Competition between in-groups and out-groups often creates an "us versus them" mentality.
Prejudice can be reduced by minimizing power differences and encouraging cooperative work toward common goals.
The Bystander Effect
The Diffusion of Responsibility: As the number of bystanders at an emergency increases, the probability that any single person will help decreases. Each person assumes someone else will take action.
The Case of Kitty Genovese ():
Kitty Genovese was murdered in New York City with witnesses hearing her cries for help.
Despite knowing something was wrong, no one intervened or effectively helped her because each witness assumed another neighbor had already called for help or would step in.
Psychological research shows that help is significantly more likely to be offered if a bystander is alone and feels the full weight of the responsibility to act.
Questions & Discussion
Regarding social roles in media: Observations were made about reality TV competition shows, noting how participants on a "tribe" begin acting in ways they normally wouldn't due to the pressure of the group and the power dynamics involved.
Regarding group work: Students discussed "social loafing" in the context of high school or college group projects, where it often feels like one person does most of the work while others "loaf" or procrastinate.
Regarding personal exceptions: A discussion occurred regarding whether good people always step in during emergencies. It was noted that fear for one's own life can overrule the impulse to help, leading individuals to run away rather than intervene.
