Ch. 4: Cognition, Consciousness, and Language Flashcards
defn: cognition
how our brains process and react to information from the world
defn: dual coding-theory
both verbal association and visual images are used to process and store information
defn: the four key components of the information processing model
- thinking requires sensation, encoding, and storage of stimuli
- stimuli must be analyzed by the brain (not responded to automatically) to be useful in decision making
- decisions make in one situation can be extrapolated and adjusted to help solve new problems (situational modification)
- problem solving is dependent not only on the person’s cognitive level, but also on the context and complexity of the problem
defn: cognitive development
the development of one’s ability to think and solve problems across the life span
what are the Piaget’s four stages of cognitive development?
- sensorimotor
- preoperational
- concrete operational
- formal operational
defn: schema
a concept, behavior, or sequence of events
defn and components: adaptation
how new information is processed
assimilation and accommodation
defn: assimilation (cognitive development)
the process of classifying new information into existing schemata
defn: accommodation
the process by which existing schemata are modified to encompass this new info
defn, char, age: sensorimotor stage
Piaget’s first stage of cognitive development
age: birth - 2 years old
- manipulate environment to meet physical needs
- coordinate sensory input with motor actions
- circular reactions
- objective permanence
- representational thought
primary circular reactions: repetitions of body movements that orig. occurred by change
secondary circular reactions: manipulation is focused on something outside the body
object permanence: objects continue to exist even when out of view
marks the beginning of representational thought: create mental representations of external objects and events
defn, char, age: preoperational stage
Piaget’s 2nd stage of cognitive development
2-7 years old
- symbolic thinking
- egocentrism
- inability to grasp conservation
- centration
symbolic thinking: the ability to pretend, play make-believe, and have an imagination
egocentrism: the inability to imagine what another person may think or feel
conservation: a physical amount remains the same even if there is a change in shape or look
centration: the tendency to focus on only one aspect of a phenomenon while ignoring other important elements
defn, char, age: concrete operational stage
Piaget’s third stage of cognitive development
7-11 years old
- conservation
- others’ perspectives (loss of egocentrism)
- logical thought with concrete objects and directly available information
defn, char, age: formal operational stage
Piaget’s fourth stage of cognitive development
11 years old +
- abstract thinking
- problem solving
- hypothetical reasoning
hypothetical reasoning: the ability to mentally manipulate variables in a number of ways
defn: fluid intelligence
solving new or novel problems, possibly using creative methods
defn: crystallized intelligence
solving problems using acquired knowledge (often procedural)
What is the relationship of fluid intelligence and crystallized intelligence with age?
Fluid intelligence: peaks in early adulthood, declines with age
Crystallized intelligence: peaks in middle adulthood, stable with age
defn: activities of daily living
eating, bathing, toileting, dressing, ambulation
defn, char, and cause: dementia
disorders and conditions characterized by a general loss of cognitive function
begins with impaired memory, progresses to impaired judgement and confusion; personality changes
most common cause: Alzheimer’s
also common: vascular dementia (high blood pressure and microscopic brain clots)
What other conditions can impact cognition?
- parenting style
- Down syndrome
- Fragile X syndrome
- fetal alcohol syndrome
- brain infections
- birth complications
- shaken baby syndrome
defn: delirium
rapid fluctuation in cognitive function that is reversible and caused by medical causes (nonphysiological)
defn: mental set
the tendency to approach similar problems in the same way
defn: functional fixedness
the inability to consider how to use an object in a nontraditional manner
what are the four types of problem solving?
- trial-and-error
- algorithms
- deductive reasoning
- inductive reasoning
defn: algorithm
a formula or procedure for solving a certain type of problem
defn and aka: deductive reasoning
aka: top-down reasoning
starts from a set of general rules, draws conclusions from the info given
defn and aka: inductive reasoning
aka: bottom-up reasoning
create a theory via generalizations
starts with specific instances and draws a conclsuion from them
what are the four types of tools we use for decision making?
- heuristics
- biases
- intuition
- emotion
defn and aka: heuristics
simplified principles used to make decisions
aka: rules of thumb
defn: availability heuristic
we based the likelihood of an event on how easily examples of that event come to mind
defn: representativeness heuristic
categorizing items based on whether they fit the prototypical, stereotypical, or representative image of the category
defn: base rate fallacy
using prototypical or stereotypical factors while ignoring actual numerical info
defn: disconfirmation principle
the evidence obtained from testing demonstrated that the solution does not work
defn: confirmation bias
the tendency to focus on info that fits your beliefs and reject info that goes against them
defn: overconfidence
the tendency to erroneously interpret one’s decisions, knowledge, and beliefs as infallible
defn: hindsight bias
the tendency to overestimate their ability to predict the outcome of events that already happened
defn: belief perserverance
the inability to reject a particular belief despite clear evidence to the contrary
what are the four concepts that impede a person’s analysis of available evidence?
- confirmation bias
- overconfidence
- hindsight bias
- belief perserverance
what is the recognition-primed decision model?
it’s basically intuition!
the brain sorts through a wide variety of info to match a pattern
experience helps this!
what are Gardner’s 8 defined types of intelligence?
- Linguistic
- Logical-mathematical
- Musical
- Visual-spatial
- Bodily-kinesthetic
- Interpersonal
- Intrapersonal
- Naturalist
what are the types of intelligence in Sternberg’s triarchic theory? describe them.
- analytical intelligence (evaluate and reason)
- creative intelligence (solve problems using novel methods)
- practical intelligence (dealing with everyday problems at home or work)
what are the four components of emotional intelligence?
- express and perceive emotions of ourself and others
- comprehend and analyze our emotions
- regulate our emotions
- awareness of how emotions shape our thoughts and decisions
defn: g factor
general intelligence factor
performance on different cognitive tasks is often positively correlated (indicating an underlying factor playing a role)
defn: consciousness
one’s level of awareness of the world and one’s own existence within that world
what are the 4 states of consciousness?
- alertness
- sleep
- dreaming
- altered states
defn: physiological arousal
increased heart rate, breathing rate, blood pressure, cortisol etc.
we exp. a certain level while alert
defn, func, and injury: reticular formation
neural structure in the brainstem
communicates with fibers from the prefrontal cortex to keep the cortex awake and alert
injury: coma
