Bounded Rationality
refers to the idea that human decision-making is limited by cognitive constraints, time, and available information, leading to "satisficing" rather than optimal, rational decisions
Availability Heuristic
describes that people make judgements about the likelihood of events based on how easily examples come to mind.
Personal Experience Bias
describes people’s tendency to assume their personal, subjective experiences represent objective truth or universal norms.
Representativeness Heuristic
describes that people evaluate probabilities based on similarity (based on the degree to which A is representative of B).
Base Rate Neglect
refers to judgements that neglect the underlying probability of an event.
Conjuction Fallacy
describes people’s tendency to assume that a specific condition (both A and B) is more likely than a more general condition.
Law of Small Numbers
describes people’s biased belief that small samples should perfectly represent the population from which they are drawn.
Regression to the Mean
After an extreme, the most likely next trial/sample will be closer to the average (mean).
Anchoring
describes judgements based on an initial (sometimes arbitrary) value and insufficiently adjusting.
Gigerenzer’s critique
Additionally asks prescriptive question: When should people rely on a given heuristic rather than a complex strategy to make more accurate judgments?
“Less is more” Effects
???
Recognition Heuristic
describes the often accurate rule of thumb that if one of two objects is recognized and the other is not, the recognized object can be inferred to have a higher value regarding a specific criterion.
Ecological rationality for heuristics
Depending on the environment, a heuristic can be ecologically rational (best adapted to the situation at hand)

ABC model of attitudes (affect, behavior, cognition)
Attitude - an evaluation toward an object (person/ behavior/ group/ idea)
“ABC” model
Affective → i love coffee
Behavioral → I have coffee every morning
Cognitive → Coffee keeps me alert when I’m tired`
Mere Exposure
Repeated exposure → increased liking (even without awareness)
Mechanism:
fluency → feels good → misattributed as liking
Associative learning
Classical conditioning:
Pairing a neutral stimulus with an inherently positive or negative stimulus
leads to transfer of evaluation to the neutral stimulus.
Operant conditioning:
Rewarding or punishing a behavior increases the likelihood of that behavior.
Observational Learning
Attitudes are learned from
● Parents
● Peers
● Media
● …
Self-Perception Theory
we form attitudes to explain our behavior. This mainly applies with attitudes are unclear or weak.
Attitude

Cognitive dissonance theory
refers to mental discomfort that is experienced due to inconsistency between beliefs, values, attitudes, and behaviors. People are motivated to reduce this discomfort (the dissonance) by changing behaviors, justifying actions, or ignoring conflicting information.
Explicit Attitudes
are attitudes that people can directly describe. They are conscious, deliberate, and
reportable.
Implicit Attitudes
are automatic evaluations that can influence perception, judgment, and behavior without deliberate conscious intention. They are fast, automatic, difficult to control continuously, and potentially inconsistent with explicit beliefs
MODE Model
a dual process model in the domain of attitudes and behavior. MODE = Motivation and Opportunity as Determinants of the attitude-behavior relation
The implicit associations test
???
Procedure and principle behind IAT
Core assumption:
People respond faster when two concepts are strongly associated in memory.
The IAT measures implicit evaluative associations.
→ The IAT reveals automatic or “hidden” biases that might not appear in
self-report measures.
Criticism of IAT
Methodologically:
● No strong test-retest-reliability
Performance often
context/mood-dependent
● Performance can easily be
deliberately influenced
● IAT scores don’t predict
discriminatory behavior
Interpretations:
● No clear definition of implicit bias
● IAT score more reflective of
familiarity (memory) rather than
liking*
● People who have a smaller IAT
don’t necessarily have less bias
● IAT training definitely doesn’t
reduce discriminatory behavior
Stereotype
a generalized belief, positive or negative, about the characteristics of members of a group that is applied to most members of the group. Stereotypes are schemas to categorize a group of people.
Prejudice
refers to attitudes towards a person or a group of people or a situation prior to evaluating the evidence. This attitude usually includes negative affect.
Discrimination
refers to negative behavior toward members of an out-group.
Outgroup
A group that we don’t belong to and/or that we view as fundamentally different from us.
Stereotype content model
According to the SCM, the content of stereotypes varies along two dimensions: competence and warmth.
Competence
Is this group capable, intelligent, skilled?
Warmth
Is this group friendly, trustworthy, well-intentioned?
BIAS Map
BIAS = Behavior from Intergroup Affect and Stereotypes
Warmth predicts:
● Active behaviors
● Helping vs harming
Competence predicts:
● Passive behaviors
● Inclusion vs neglect
Stereotype threat theory
defined as “socially premised psychological threat that arises when one is in a situation or doing something for which a negative stereotype about one’s group applies” (Steele & Aronson, 1995)
Social identity theory
describes how people readily self-identify as belonging
part of a group (and others as not belonging to that group).
Minimal group paradigm
???
3 stages of social identity
1. Social categorization
Categorizing people (including oneself) are belonging to a group to
understand the social environment
2. Social identification
Adopting the identity of the group we have categorized ourselves as
belonging to, causing us to act in ways we believe is characteristic of that
group
3. Social comparison
Comparing our in-group with out-groups to enhance self-esteem.
Ingroup favoritism
describes the tendency to favor members of one's own group over out-group members in evaluations, resource allocation, and behavior.
Outgroup homogeneity effect
describes people’s tendency to perceive members of their own group as diverse and unique, while viewing members of other groups as more similar to each other (more homogenous).
Ultimate attribution error
describes people’s tendency to systematically attribute negative behaviors by out-group members to internal, dispositional flaws while attributing positive behaviors to external, situational factors.
Realistic conflict theory
states that intergroup hostility, prejudice, and discrimination arise from real or perceived competition between groups for limited resources, when groups compete in a "zero-sum" scenario.
Integrated threat theory
describes how real or perceived threats from an out-group generate prejudice and discriminatory behavior by an in-group.
Habit breaking model of prejudice
???
Stereotype replacement
This strategy involves replacing stereotypical responses for non-stereotypical
responses. It requires:
● recognizing that a response is based on stereotypes
● labeling the response as stereotypical, and
● reflecting on why the response occurred
counter-stereotype imaging
This strategy involves imagining in detail counter-stereotypic others (Blair et al.,
2001). These others can be
● abstract (e.g., smart Black people)
● famous (e.g., Barack Obama) or
● non-famous (e.g., a personal friend)
individuating
This strategy relies on preventing stereotypic inferences by obtaining specific
information about group members (Brewer, 1988, Fiske and Neuberg, 1990).
Using this strategy helps people evaluate members of the target group based on
personal, rather than group-based, attributes.
perspective taking
This strategy involves taking the perspective in the first person of a member of a
stereotyped group. It increases psychological closeness to the stigmatized group,
which improves automatic group-based evaluations (Galinsky & Moskowitz,
2000).
contact
This strategy involves seeking opportunities to encounter and engage in positive interactions with out-group members.
Intergroup contact theory
Contact between groups under optimal conditions could effectively reduce
intergroup prejudice
Allport’s “optimal conditions” for contact
○ equal status between the groups
○ common goals
○ intergroup cooperation
○ institutional support
Reduction of intergroup anxiety
Intergroup anxiety refers to feelings of threat and uncertainty that people
experience in intergroup contexts. These feelings grow out of concerns about
● how they should act
● how they might be perceived
● whether they will be accepted
“Parasocial contact hypothesis”

Affect
is often used as an umbrella term for various emotional experiences. In
psychology, it refers to a diffuse (not specific), immediate, observable
manifestation of emotion.
Emotion
refers to a more specific experience, typically in response to particular
events, situations, or thoughts. It involves both physiological responses (eg,
changes in heart rate) and psychological experiences (eg, the subjective
experience of joy or fear).
Mood
refers to a prolonged, relatively weak and undifferentiated feeling.
Theories of emotion: Darwin
“The expression of the emotions in man and
animals” (1872)
● Documented visible expressions of emotions, such as
facial and body expressions that characterize fear,
anger, or happiness
● Many expressions are conserved across species
● Expressions are innate (not learned)
● Provide signals to other animals
● (e.g. about to attack, ready for sexual advances)
Theories of emotion: Ekman
There are six (categorically distinct) basic emotions:
● Happiness
● Sadness
● Disgust
● Anger
● Fear
● Surprise
Criteria for basic emotions:
● Automatic, rapid onset, brief duration
● Distinctive universal signals, physiology
● Evolved for a distinct survival problem
Theories of emotion: Russell & Barrett
emotions reside on a space between two dimensions:
● Valence (positive – negative)
● Arousal (high – low)
Mood-congruent cognition
describes people’s tendency to notice, interpret, and remember details that match their
current emotional state.
Misattribution of arousal
is a psychological phenomenon where a person incorrectly identifies the source of their physiological arousal (e.g., elevated heart rate, adrenaline rush) and mislabels it as an emotion, such as romantic attraction, fear, or anxiety.
