Lecture 11 Flashcards
What is perception?
It is the process by which sensations are selected, organized and interpreted.
It is influenced by the perceiver (individual
differences), target (eg. stimuli perceptors), and situation (Time, place).
Attribution theory
Theory seeks to explain how and why people make these causal attribution.
There are two general types of attributions that people make:
- Internal/ Personal attributions
- External/ Situational attributions
Attribution theory: Three factors for determination
- Distinctiveness: Whether an individual displays different behaviors in similar situations.
- Consensus: The similarity between the actor’s behavior and the behavior of other people in similar circumstances.
- Consistency: whether someone acts the same way in a given situation each time it occurs.
Fundamental attribution error
When judging others, we tend to underestimate the influence of external facotrs and overestimate the influence of internal factors.
The situation is not salient when making attributions for behavior of others, but it is salient, when making attributions for one’s own behavior.
Self-serving Bias
When judging ourselves, we attribute our own successes to internal factors and failures to external factors.
Halo Effect
Drawing a general impression based on a single characteristic.
eg. Attactiveness -> positive characteristic (kind)
Contrast effect
We do not evaluate a person in isolation.
Our reaction to one person is influenced by other persons we have recently met.
Stereotyping
- Judging someone on the basis of the group to which the person belongs. (i.e. nationaly, gender, etc)
- This is a mean of simplifying a complex world, and it permits us to maintain consistency.
- Involves making generalizations.
Three Models of Decision‐Making: Rational Decision-making
- Have complete information
- Base decisions on facts & objective information
• Able to identify all the relevant options in an
unbiased manner
• Choose the option with the highest utility
Three Models of Decision‐Making: Bounded rationality
Most people respond to a complex problem by reducing the problem to a level at which it can be readily understood
Three Models of Decision‐Making: Intuition
the ability to understand something immediately, without the need for conscious reasoning.
Likely from instinctive feeling than from conscious reasoning.
Individual Cognitive Biases Limiting Rational Decision-Making:
Representativeness Heuristic
it is a cognitive bias in which an individual categorizes a situation based on a pattern of previous experiences or beliefs about the scenario.
It can be useful when trying to make a quick decision but it can also be limiting because it leads to stereotypes.
Individual Cognitive Biases Limiting Rational Decision-Making: Wishful thinking (Confirmation Bias)
What we want to happen influences our judgments about what will happen.
People overestimate the probability of success of entities with which they feel associated.
eg. people who do not want to vacunate their babys (my baby will nnot be infected by viruses)
Individual Cognitive Biases Limiting Rational Decision-Making:
Escalation of commitment (Sunk costs)
Escalation of commitment happens when someone continues to dedicate resources, including time and money, to a failing course of action.
Rationally, should make decisions based on prospects and should not be influenced by sunk costs
Individual Cognitive Biases Limiting Rational Decision-Making:
Selective Attention/ Perception
Attention is a limited resource; we selectively attend to features of a person, object, or event that stand out.
It enables us to focus on something without being distracted by what is in the background
