What’s selective vs. divided attention?
Selective attention refers to the process by which we focus on one aspect in our environment while ignoring others.
Divided attention is multitasking.
What is cocktail party effect?
The cocktail party effect is a specific instance in which we may suddenly shift our attention to something that was previously ignored because of some cue that draws our attention
What is controlled versus. automatic processing?
Controlled processing requires attention (studying), while automatic processing does not (brushing teeth).
What does Information processing theory include?
1) thinking- includes perception of stimuli, encoding stimuli and storage of info.
2) analysis of stimuli - part of decision making, stimuli are altered and analyzed by brain.
3) Situational modification: stored decision making and problem solving experiences from past can be extrapolated t solve new problems.
4) Obstacle evaluation: individual’s skill level in problem solving does not depend solely on cognitive development level but largely on nature and context of problem/ obstacle.
Who is Jean Piaget ?
Father of developmental psychology and major contributor to cognitive theory.
What are schemas? what did JP believe about them?
Piaget believes schemas were an important part of how we learn. Schemas are patterns of thought that we use to create categories of information or behavior and to understand the relationship that exists among those categories.
What are real life examples of schemas?
1) outline plan to do well at school.
2) Schema of what fits in description of dog.
What are Piaget’s stages of cognitive development?
1) sensorimotor (0-2 years old)- coordination of senses with motor response.
2) pre operational (2-7)- symbolic thinking + use of proper syntax and grammar. Strong intuition and imagination.
3) concrete operational (7-11years old) - concepts attached ton concrete situations. Understand time, space an quantity.
4) formal operational (+11) theoretical, counterfactual and hypothetical thinking. Strategy and planning become possible.
What are age related physical changes in the brain?
Brain shrinks in size and neural plasticity decreases.
What is neural plasticity?
Brain’s ability to change structure and function to accommodate new memories, make new connections and create new motor skills.
What kind of memory do you lose as you age?
working memory, rote memory but not semantic memory.
What structure of the brain loses neurons t the fastest rate?
Frontal lobe and corpus callossum lose neurons at the fastest rate. Cerebellum loses 25% of neurons.
What are barriers to effective Problem solving?
1) mental set= predetermined mental framework for approaching a problem’ relying on approaches and solutions that have worked in the past.
2) Functional Fixedness: example of a mental set in which, when solving a problem, we can only visualize using an object or tool in the ways we have seen it used previously.
Explain Duncker’s candle problem and provide a conceptual definition for functional fixedness. Provide two additional real-life examples of functional fixedness.
Duncker’s candle problem is a task that is used to determine how certain types of cognitive bias might influence one’s ability to solve a problem. During this task, individuals are asked to fix a burning candle to a corkboard without dripping wax onto a table.
he individuals are provided (or are shown a picture of) a book of matches, a box of thumbtacks, and a candle. The correct solution is to empty the box of thumbtacks, secure the box to the wall using the thumbtacks, place the candle in the box, and to light the candle. Many people struggle in solving this task because they cannot conceive of using the box of thumbtacks for anything other than pinning something to a cork board.
What’s cognitive bias?(3)
An error in thinking that leads to inaccuracy, illogical thought, a lack of objectivity, a failure to consider all available options or consequences, a prejudice toward one approach or outcome.
What are approaches to PS? (3)
1) Trial and Error: try, test, multiple and discover what works and what doesn’t- this is only effective when there are relatively few available options.
2) Algorithms: Mathematical formulat or step by step, flowchart like approach.
3) Heuristics: “Rules of Thumb”- heuristics can be helpful in problem solving, but can also cause functional fixedness and a lack of cognitive flexibility.
4) intuition: one’s gut feeling - unconsciously applying heuristic or mental set.
5) deductive reasoning: conclusions ar gebased on assumed premises aka TOP DOWN processing.
6) inductive reasoning: BOTTOM UP processing.
In approaches to PS; there’s three types of heuristics, what are they?
1) representative heuristics: reliance on prototypes or stereotypes as a shortcut to making a decision or judgment.
2) availability heuristic: favoring the most easily recalled or imagined solution as a shortcut to making a decision or judgment.
3) Anchoring and adjustment heuristic: giving higher priority o the very first piece of information received and/or framing subsequent information around it.
Label the following as examples of inductive or deductive reasoning. Justify your answers. a) Some people believe dogs are more intelligent than cats. My dog can play fetch, but my cat cannot. Therefore, dogs are smarter than cats.
b) The veterinarian visited all of the horses in the county last week. All of the horses the veterinarian visited were brown. Therefore, all of the horses in the county are brown.
a) inductive
b) deductive
what’s confirmation bias?
the tendency to interpret new evidence as confirmation of one’s existing beliefs or theories.
what’s overconfidence?
the quality of being too confident; excessive confidence.
what’s belief perseverance?
People tend to hold on to their beliefs even when it appears that they shouldn’t. Belief perseverance is the tendency to cling to one’s initial belief even after receiving new information that contradicts or dis- confirms the basis of that belief.
wha’t base rate fallacy?
also called base rate neglect or base rate bias, is a formal fallacy. If presented with related base rate information (i.e. generic, general information) and specific information (information only pertaining to a certain case), the mind tends to ignore the former and focus on the latter.
1) Suppose it is discovered that the kidney has a hormone function that was previously unknown and is currently the subject of further investigation. A researcher exhibiting functional fixedness is likely to favor which new kidney function? A) Secretion of gonadotropins B) Secretion of oxytocin C) Regulation of aldosterone levels D) Regulation of triiodothyronine levels
C- The functional fixedness bias suggests that a person has a hard time visualizing a tool or object as having a use or application different from the one with which they are accustomed. Applied to kidney function, researchers would be biased toward a new kidney function that is closely related to what they normally expect the kidney to do.
what is spreading activation?
remembering words that are associated to a lit of words previously seen but not there. method for searching associative networks neural networks or semantic networks.
