c) it is best suited to considering and evaluating complex evidence
representative heuristic
classifying something according to the typical case. Unfortunately this approach often ignores base rate information
Availability Heuristic
judgement based on how easily something comes to mind
Heuristics
mental shortcuts used to make quick and efficient judgments. Heuristics address cognitive judgment. - availability - representativeness - anchoring and adjustment
schemas
organize our knowledge and influence what we notice, think about, and remember. An associative network similar to a concept map
behavioral confirmation
our behaviors elicit from others what we originally expected. Belief that we have in our minds create the social reality that we experience
attentive process
requires intention and effortt
self-fulfilling prophecy
step 1: Perceiver forms expectancy about Target PERCEPTUAL CONFIRMATION Step 2: Perceiver interprets Target behavior through bias of expectation. Step 3: Perceiver acts according to biased perception; Target responds in kind to perceiver's behavior BEHAVIORAL CONFIRMATION
priming
the process by which recent experiences increase the accessibility of a schema, trait, or concept. Can impact behavior even without awareness
Syntax
the rules for combining words into grammatically sensible sentences in a given language
Overconfidence
the tendency to be more confident than correct—to overestimate the accuracy of our beliefs and judgments.
attention
the tendency to respond to and remember some stimuli more than others
functional fixedness
the tendency to think of things only in terms of their usual functions; an impediment to problem solving
spreading activation
thinking about one of the concepts shown in this figure will activate, or prime, the concepts linked to it
cogntition
thinking and using knowledge
automatic processing
unconscious encoding of incidental information, such as space, time, and frequency, and of well-learned information, such as word meanings pros: more efficient, much faster, sometimes more accurate cons: prone to certain errors, less controlled, overgeneralizations
preattentive process
we can notice things that stand out without effort
phonology
Rules for combining sounds -> words Phonemes (smallest units of sound) Morphemes (smallest units of meaning)
framing effect
The decision-making bias that results from the way a decision, question, or problem is worded
bad part of schemas
can distort what we remember and what we see and can influence us in unexpected ways
Priming a concept is responsible for which of the following? a) change blindness b) the stroop effect c) the stop signal d) spreading activation
d) spreading activation
controlled processing occurs when...
people have the ability and motivation to do so
people will buy meat that claims "90% fat free" but not one that says "contains 10% fat" this is an example of which of the following? a)overconfidence b)the framing effect c) sunk cost effect d) inappropriate use of the availability heuristic
b) the framing effect
controlled processing
"explicit" thinking that is deliberate, reflective, and conscious pros: more controlled and intentional, often more accurate cons: time-consuming, uses up resources, not always more accurate
what schemas do we use?
- AVAILIBILITY Do you have a schema for this person/topic/attitude? if you are not familiar with it then it is not available - ACCESSILIBILTY the ease with which a schema can be retrieved from memory and used in a given situation chronic vs. temporary accessibility
what schemas get used?
- schemas that are chronically accessible due to past experiences or repeated activation over time -schemas that are temporarily accessible. Related to a current goal or from a recent experience
Bargh, Chen, & Burrows (1996)
-Participants complete a scrambled sentence task, then get experimenter in hall to proceed with study. The scrambled sentences had different words related to either rudeness, politeness or neutral -Polite condition (e.g., He was very considerate); rude condition (e.g., He was very inconsiderate); neutral condition -does subject interrupt experimenter? -interruption-> rude condition
where do schemas come from?
-direct experience - indirect experience - media - culture - socialization
Stroop Effect
Explains the decreased speed of naming the color of ink used to print words when the color of ink and the word itself are of different colors.
language
Human language is unique in that it is productive productivity: the ability to combine words into new sentences that express an unlimited number of ideas
Maximizers vs. Satisficers
Maximizing choices: Seek and accept only the best (or aspire to do so): • Price • Quality • Fit • Etc. Satisficing choices: Settle for something that is good enough (merely excellent?) • Criteria • Monitoring • End of story
Semantics
Meaning of words and sentences surface level vs. deeper meaning
Snyder, Tanke, & Berscheid (1977)
Men told to have phone conversation with woman and shown picture of attractive/unattractive woman beforehand and responses were coded for openness and warmth -attractive females had more open and warm responses
factors that impact motivation
Need for Cognition Personality variable: extent to which people engage in and enjoy effortful activities Some people just like to think more than others Accountability Responsibility -> Engagement and Care Bosses, Project Leaders, etc. Personal Relevance Personal stakes -> Engagement and Care Classic Example: Opinions about tuition increases Task/Decision Importance More impactful -> Engagement and Care
Bransford and Johnson (1972)
One third of participants heard that paragraph. One third of participants were told it was about laundry after hearing it. One third of participants were told it was about laundry before hearing it. The only participants who really understood or remembered anything about the passage were those who knew it was about laundry before hearing it. Prior knowledge about the topic activated a "laundry" schema, allowing for better retention and comprehension
language and thinking
Thinking involves mental manipulation of knowledge to reach a goal, solve a problem, etc. Language influences how we think and perceive the world Language ≠ Communication It is a highly-developed mode of communication Birds tweet, bees dance, dogs bark, but we wouldn't call what they're doing using a "language" Languages have grammar: rules that allow us to use arbitrary symbols to convey meaning
