Unit 5 & 6, Lindsay & Unit 7, Elaina - Test 2 Flashcards
What is the nature of intelligence?
Defined as an individual’s ability to understand complex ideas, to adapt effectively to the environment, to learn from experience, to engage in various forms of reasoning, and to overcome obstacles by taking thought. There are mant different points of view about the nature of intelligence, and it continues to be debated.
What was Binet’s role in intelligence testing?
He created the first valid intelligence test
What is the definition of Standford-Binet intelligence quotient (IQ)?
An index of intelligence originally derived by dividing mental age by chronological age & then multiplying by 100
What is the Wechsler test?
A test for people 16 & older, the test contains both verbal and non verbal subtests, which yeild seperate verbal and performance IQ scores as well as overall IQ.
What is the Standford-Binet test?
It is an individually administered IQ test for those aged 2 - 23 testing in four subscales: verbal reasoning, quantitative reasoning, abstract visual reasoning, & short-term memory.
What is the difference between group intelligence test and individual intelligence test?
Individual testing is expensive and time-consuming and administered to one individual at a time by one psychologist. With Group testing IQ testing is not done, it’s done on a budget and in a shorter period of time.
Describe the pattern of distribution of IQ scores observed in the general population:
When large populations are measured on mental characteristics such as intelligence or on physical characteristics the test scores or results usually conform to the bell-shaped distribution known as the NORMAL CURVE.
Most of the scores cluster around the mean (average). The farther the score deviate (move away) from the mean, above or below, the fewer people there are.
Test score below 70 is in the range of mental disability.
What is the dividing line between normal intelligence and developmental disability?
People who have an IQ below 70 and they find it hard to care for themselves and relate to others. People who range from 60 -55 are considered mildly retarded. 40 - 55 are moderately retarded, and from 25-40 are severely retarded, below 25 are profoundly retarded.
What do IQ scores predict?
IQ scores can predict success and failure. They are fairly good predictors of academic achievement and sucess in school.
What are the problems associated with IQ tests?
Abuses occur when people are judged solely on their scores on ontelligence tests. Intelligence test do not measure attitude and motivation, which are critical ingredients of success
What is the controversy over nature-nurture as it pertains to intelligence?
The debate over whether intelligence and other traits are primarily the result of heredity or environment
What is emotional intelligence?
Emotional intelligence is the ability to apply knowledge about emotions to everyday life.
What is mental imagery?
The ability to represent or picture a sensory experience in our mind.
Define the term concept:
A label that represents a class or group of objects, people, or events sharing common characteristics or attributes
Define the term concept formation:
Concept formation is an active, orderly, and systematic way, rather than in a random, informal, & haphazard way.
How does concept and concept formation aid in thought processes?
Our thinking and concept formation are somewhat fuzzy, not clear cut and systematic.Sometimeswe identify objects based on a memorized list of features or attributes that are common to instances of a concept. We picture a prototype of a concept.
What are the three problem-solving techniques?
The three problem-solving techniques are:
1) Trial and Error-An approach to problem-solving in which one solution after another is tried until a solution is found.
2) Algorithm- A systematic step by step procedure that guarantees a solution to a problem
3) Heuristic- A problem method that offers a promising way to attack a problem & arrive at a solution, although it does not guarantee a success
How does mental set and functional fixedness block problem-solving?
Mental set means we get into a rut in our approach to problem solving, continuing to use the same old methods even though other methods might be better.
functional fixedness is the failure to use familiar objects in novel ways to solve problems We tend to see objects only in terms of their customary functions.
What is the relationship between creativity to divergent thinking?
Creativity- the ability to produce original, appropriate, and valuable ideas and/or solutions to problems
Divergent thinking- Producing one or more possible ideas, answers, or solutions to a problem rather than a single, correct response.
How does creativity relate to intelligence?
Researchers indicates that there is only a weak to moderate correlation between creativity and IQ.
any event or object in the environment to which an organism responds
stimulus
a relatively permanent change in behaviour, capability or attitude that is acquired through experience and cannot be attributed to illness, injury or maturation
learning
a process through which a response previously made only to a specific stimulus is made to another stimulus that has been paired repeatedly with the original stimulus
classical conditioning
a stimulus that elicits a specific response without prior learning; eg. food
unconditioned stimulus
a response that is invariably elicited by the unconditioned stimulus without prior learning; eg. salivation in response to food
unconditioned response
a neutral stimulus that, after repeated pairing with an unconditioned stimulus, becomes associated with it and elects a conditioned response; eg. the tone
conditioned stimulus
a response that comes to be elicited by a conditioned stimulus as a result of its repeated pairing with an unconditioned stimulus; eg. salivation in response to the tone
conditioned response
the weakening and often eventual disappearance of learned response, by repeated presentation of the conditioned stimulus without the unconditioned stimulus; eg.
extinction
the reappearance of an extinguished response (in a weaker form) when an organism is exposed to the original conditioned stimulus following a rest period; eg.
spontaneous recovery
in classical conditioning, the tendency to make a conditioned response to a stimulus that is similar to the original conditioned stimulus
eg. a child attacked by a dog can easily develop a long-lasting fear of all dogs
generalization
the learned ability to distinguish between similar stimuli so that the conditioned response occurs only to the original conditioned stimulus but not to similar stimuli
eg. this ability has survival value in that we know the difference between a rattlesnake and a garter snake
discrimination:
- occurs when a neutral stimulus is paired with an existing conditioned stimulus, becomes associated with it, and gains the power to elicit the same conditioned response
higher-order conditioning
State the basic principles of operant conditioning:
in operant conditioning, the consequences of behaviour are manipulated to increase or decrease the frequency of a response or to shape an entirely new response.
what is operant conditioning?
- a type of learning in which the consequences of behaviour tend to modify that behaviour in the future (behaviour that is reinforced tends to be repeated; behaviour that is ignored or punished is less likely to be repeated).
technique that reinforces any movement in the direction of the desired response, and gradually guiding the responses closer and closer to the ultimate goal
shaping
example of shaping
Even though the B that Billy wrote looked more like a D, his teacher, Mrs. Chen, praised him because it was better than his previous attempts.
Compare and contrast positive reinforcement and negative reinforcement
positive reinforcement: a reward or pleasant consequence that follows a response and increases the probability that the response will be repeated; EG. salary raises, promotions, awards, bonuses, good grades, and candy
negative reinforcement: the termination of an unpleasant stimulus after a response in order to increase the probability that the response will be repeated; EG. turning on one’s air conditioner to terminate heat or getting out of bed to turn off a faucet to avoid listening to the annoying “drip, drip, drip.”
Differentiate between primary reinforcers and secondary reinforcers and examples of each kind
primary reinforcer: reinforcer that fulfills a basic physical need for survival and does not depend on learning; EG. food, water, sleep, sex, and the termination of pain
secondary reinforcer: neutral stimulus that becomes reinforcing after repeated pairing with other reinforcers; EG. attention from others is a powerful type of this reinforcer
4 factors that influence operant conditioning:
- magnitude of reinforcement
- immediacy of reinforcement
- level of motivation
- schedule of reinforcement
3 factors that influence the effectiveness of punishment
- timing of application
- intensity of application
- consistency of application
Compare and contrast classical and operant conditioning:
- In classical conditioning, the focus is on what precedes the response. In operant conditioning, the focus is on what follows the response.
- Generally, in classical conditioning, the subject is passive and responds to the environment rather than acting upon it. In operant conditioning, the subject is active and operates on the environment.
COGNITIVE LEARNING
learning from using reasoning, intuition and perception
Discuss the factors which determine whether or not modelling or observational learning will occur
The effectiveness of the model is related to his/her status, competence and power. Other factors are sex, age, attractiveness, and ethnic status.
Whether or not learned behaviour is actually performed depends largely on whether the observed models are rewarded or punished for their behaviour and whether the individual expects to be rewarded for the behaviour.
DESCRIBE THE 3 PROCESSES INVOLVED IN THE ACT OF REMEMBERING
- encoding: transforming information into a form that can be stored in short-term or long-term memory
- storage: the act of maintaining information in memory
- retrieval: the act of bringing to mind material that has been stored in memory
DEFINE SENSORY MEMORY
As information comes in through our senses, virtually everything we see, hear, fee, or otherwise sense, is held in sensory memory but only for the briefest period of time.
Sensory memory normally holds visual images for a fraction of a second and holds sounds for about 2 seconds.
LIST THE CHARACTERISTICS OF SHORT-TERM MEMORY
- very limited capacity; short duration
- capacity is about 7 (plus or minus 2) different items or bits of information at one time
- used when we carry on a conversation, solve a problem or look up a telephone number and remember it just long enough to dial it.
- “Working memory”
- codes information according to sound and can also hold visual images, and store information in semantic form (i.e., according to meaning).
- stimulus tends to fade significantly after 20-30 seconds if it is not repeated.
EXPLAIN HOW DISPLACEMENT AND REHEARSAL AFFECT SHORT-TERM MEMORY
displacement: occurs when short-term memory is filled to capacity; each incoming item pushes out an existing item, which is then forgotten
rehearsal: the act of purposely repeating information to maintain it in short-term memory or to transfer it to long-term memory
LIST THE CHARACTERISTICS OF LONG-TERM MEMORY
- virtually unlimited capacity; long duration
- no known limits to the storage capacity
- holds all the knowledge we have accumulated, the skills we have acquired, and the memories of our past experiences
- the relatively permanent memory system with a virtually unlimited capacity
2 main subsystems within long-term memory:
declarative memory and non-declarative memory
DECLARATIVE MEMORY or NON-DECLARATIVE MEMORY?
“explicit memory”; the subsystem within long-term memory that stores facts, information, and personal life experiences
declarative memory
DECLARATIVE MEMORY or NON-DECLARATIVE MEMORY?
“implicit memory”; the subsystem within long-term memory that consists of skills acquired through repetitive practice, habits and simple classically conditioned responses
non-declarative memory
DESCRIBE THE LEVELS-OF-PROCESSING MODEL
a single-memory system model in which retention depends on how deeply information is processed
6 CAUSES OF FORGETTING
- encoding failure
- consolidation failure
- decay theory
- interference
- motivated forgetting
- retrieval failure
CAUSE OF FORGETTING: forgetting resulting from material never having been put into long-term memory
ENCODING FAILURE
CAUSE OF FORGETTING: any disruption in the consolidation process that prevents a permanent memory from forming
CONSOLIDATION FAILURE
CAUSE OF FORGETTING: a theory of forgetting that holds that the memory trace, if not used, disappears with the passage of time
DECAY THEORY
CAUSE OF FORGETTING: the cause of memory loss that occurs when information or associations stored either before or after a given memory hinder our ability to remember it
INTERFERENCE
