an inability to adopt any different or new perspective on a problem. Mental set and functional fixedness (being only able to come up with an object for the purpose it was intended
People are often very limited in the ways they think about objects, concepts, and people. When something is thought of only in terms of its functionality, then the person is demonstrating functional fixedness. This type of thinking is narrow and limited, often inhibiting the problem solving process.
the extent to which differences in a trait can be attributed to our genetic makeup is important in trying to understand human behavior. Also, keep in mind that genes and environment do not occur in isolation, but interact with each other. As a result, you are who you are, and you act and think the ways you do because of the combination of your heritability and your environment.
type of learning or problem solving that happens all-of-a-sudden through understanding the relationships various parts of a problem rather than through trial and error.
is a measure of variation (or variability) that indicates the typical distance between the scores of a distribution and the mean
Consistency and objectivity of how tests are administered and scored. Enables meaningful comparisons for a group
All tests are designed to measure something; hopefully something specific. If the test does indeed measure what it is intended to measure, then we can say that the test is valid
help disentangle the relative importance of environmental and genetic influences on individual traits and behaviors. Twin research is considered a key tool in behavioral genetics and related fields
an inclination to present or hold a partial perspective at the expense of (possibly equally valid) alternatives
how do we solve problems?
through algorithms and heuristics. Algorithms: Benefits- system that guarantees a solution and accurate Drawbacks- time-consuming and resource extensive .
Heuristics: "rule of thumb" - general way of thinking about things, sometimes it works, sometimes it doesn't . Benefits- quick and pretty much accurate Drawbacks- not guaranteed the correct solution.
how are mental set and functional fixedness related?
they are both examples of fixation. Mental set- mental "tool box" that you use for certain types of problems. It proposes how we think and refers to our tendency to approach a problem with a mindset of what has worked for us previously. Functional fixedness- only thinks of an item for the purpose it was intended (ex. The brick). Think of only the familiar functions for objects without imagining alternative uses.
what does "g" stand for?
general intelligence. It is a statistic used to model the mental ability underlying results of various tests of cognitive ability. Spearman coined the term general intelligence after observing how school children's grades in unrelated courses were positively correlated. Spearman reasoned that these correlations reflected the influence of a dominant factor, which he termed "general intelligence".
who designed the first intelligence test?
Alfred Binet and is known as the Binet - Simon scale. The test focuses on things such as attention, memory and problem-solving skills. The purpose of the test was to identify the French children who would need special assistance in classes after the French Government signed a law stating that all children must attend school. Binet suggested the concept of a mental age, or a measure of intelligence based on the average abilities of children of a certain age group.
different theories of multiple intelligence
• Catell's fluid and crystallized intelligences : Fluid- general problem solving Catell's fluid and crystallized intelligences : Fluid- general problem solving ability, high= more efficient , decreases with age. Crystallized- knowledge based intelligence. Facts, etc. grows with experience.
• Stembeig's triarchic theory : Creative- new ideas. Practical- common sense, "street smarts." Analytic- traditional IQ, school, math, verbal.
• Gardner's Multiple Intelligences: everyone is intelligent in some way. Emotional intelligence. Spacial intelligence (artist). Verbal intelligence (poets). Interpersonal Intelligence (other people). Musical intelligence (composers). Logical- mathematical (scientists). Bodily-kinesthetic (dancers).
• Spearmans "g"- a basic intelligence predicts our abilities in varied academic areas.
• Thurstone's primary mental abilities- our intelligence may be broken down into seven factors: word fluency, verbal comprehension, spatial ability, perceptual speed, numerical ability, inductive reasoning, and memory.
how is an IQ score derived?
from one of several different standardized tests designed to assess intelligence. When modern IQ tests are constructed, the mean (average) score within an age group is set to 100 and the standard deviation to 15/ (mental age/chronological age)x 100
different ways to measure intelligence
Standardized tests: WISC, WAIS, Woodcock-Johnson
Biology: it may be at the genetic level? Set limit?
abilities that may get left out of traditional intelligence testing
- Different intelligences
- Low IQs, but specialized
an IQ score two deviations above the mean
states that the person is in the top 2% of that sample with a score of 130.
predictive validity and range restrictions effect on it
Be able to predict the criterion of future performance. The narrower the range, the lower the predictive power.
substantial increase in IQ scores. The tests are standardized, the average of the test results is set to 100, and their standard deviation is set to 15 points.
intellectual disability and how it is problematic
IQ < 70 = mental retardation ( two standard deviations from the mean)
some kids just miss the cut so they are put into classes that are too hard for them
standard definition of giftedness and how it is problematic
IQ > 130 = gifted (genius) ( two standard deviations above the mean)
some kids just miss the cut and are put into classes that are too easy for them
common heritibility estimate of IQ
however these are dependent on the variability of environment, variability does NOT equal genetic differences, and the more variable the environment is the lower the H.E.
