Cognition, Consciousness, and Language Flashcards
Information processing model
Brain=Computer
Cognitive development
The development of one’s ability think and solve problems across the lifespan
Adaptation
The process of classifying new information into existing schemata
Accommodation
The process by which existing schemata are modified to encompass new information
Sensorimotor Stage
The first stage of Piaget’s theory. Birth-2 yrs. A child learns to manipulate their environment in order to meet physical needs
Primary circular reactions
The repetition of a body movement that originally occurred by chance because the child finds it soothing
Secondary circular reactions
Occur when manipulation is focused on something outside the body, such as repeatedly throwing toys from a high environment
Preoperational stage
Second stage of Piaget’s theory. 2-7 yrs. The child has begun to create mental representations of external objects and events. Characterized by symbolic thinking, egocentrism, and centration
Centration
Tendency to focus on one aspect of a situation to the exclusion of others. E.g. “daddy can’t be a brother because he’s a father”
Concrete operational stage
Third stage of Piaget’s theory. 7-11. Children can understand conservation and consider the perspectives of others. Can think logically but not abstractly
Formal operational stage
Last stage of Piaget’s theory. 11+. Ability to think logically about abstract ideas
Vygotsky
Theorized that the engine driving cognitive development is the child’s internalization of his or her culture including interpersonal and societal rules, symbols, and languages
Fluid Intelligence
Consists of problem solving skills
Crystallized Intelligence
Consists of learned skills and knowledge
Delirium
A rapid fluctuation in cognitive function that is reversible and is the result of physiological issues such as electrolyte and pH disturbances, malnutrition, low blood sugar, infection, a drug reaction, alcohol withdrawal, and pain
Mental set
The tendency to approach similar problems in the same way
Functional fixedness
The inability to consider how to use an object in a nontraditional manner
Deductive (top-down) reasoning
Starts from a set of general rules and draws conclusions from the information given
Inductive (bottom-up) reasoning
Seeks to create a theory via generalization
Heuristics
Simplified principles used to make decisions; rules-of-thumb
Availability heuristic
Used when trying to determine how likely something is. Decisions using this heuristic are based on how easily similar instances can be imagined
Representativeness heuristic
Involves categorizing items on the basis of whether they fit prototypical, stereotypical, or representative images of the category
Base rate fallacy
Using prototypical or stereotypical factors while ignoring actual numerical information
Disconfirmation principle
The idea that when a potential solution to a problem fails during testing, this solution should be discarded
Confirmation bias
The tendency to focus on information that fits an individuals’ beliefs, while rejecting information that goes against them
Overconfidence
A tendency to erroneously interpret one’s decisions, knowledge, and beliefs as infallible
Belief perseverance
The inability to reject a particular belief despite clear evidence to the contrary
Intuition
The ability to act on perception that may not be supported by available evidence
Recognition-primed decision model
Explanation of intuition. The brain is sorting through a wide variety of information to match a pattern. Over time, a person has gained an extensive level of experience that her or she is able to access without awareness
Emotion
The subjective experience of a person in certain situations
Consciousness
One’s level of awareness of both the world and one’s own existence within the world. The accepted states are alertness, sleeping, dreaming, and altered states
Alertness
A state of consciousness in which we are awake and able to think
Reticular formation
A neural structure in the brainstem required to keep the cortex awake and alert
Beta waves
Have a high frequency. Occur when a person is alert or concentrating. Correspond to random neuron firing
Alpha waves
Occur when we are awake but relaxing with eyes closed. Slower and more synchronized than beta waves
Stage 1 of Sleep
As soon as you doze off. Characterized by the appearance of theta waves (CHECK THIS)
Theta waves
Characterized by irregular waveforms with slower frequencies and higher voltages
Stage 2 of Sleep
As you fall more deeply asleep. Theta waves along with sleep spindles and K complexes
Slow-wave sleep
Stage 3 and 4 of deep sleep, when EEGs reveal large, regular delta waves and sleepers are hard to awaken
Delta waves
Low frequency, high-voltage sleep waves
Non-Rapid Eye-Movement (NREM) sleep
Stages 1-4
