Measurement Of Intelligence In Psychology

Measurement Of Intelligence In Psychology – Psychologists cannot agree on a precise definition of intelligence. “Boring intelligence is what intelligence tests measure.” Intelligence: Global ability to think logically, act purposefully, and deal effectively with the environment Intelligence: Others focus on higher thought processes – reasoning, understanding, judgment Many agree that intelligence includes the ability to understand theoretical concepts (abstract thinking). . ©John Wiley & Sons, Inc.

Galton’s theory (mid-1800s) that people with better senses have more knowledge, research has shown that different sensory abilities are weakly correlated with each other. It has also been shown that measures of sensory ability are not highly correlated with intelligence LO 9.1 Sir Francis Galton.

David Wechsler (1939) developed an intelligence test for adults, consisting of 11 (now 15) subscales that measure verbal and non-verbal IQ (or performance). Today’s most popular IQ tests are the WAIS – Adults; WISC – Children; WPPSI – Preschool Children ©John Wiley & Sons, Inc. Huffman: Psychology in Action (8e)

Those designed to test general ability in a specific domain or predict academic achievement are highly correlated with IQ (.7–.8). Training courses have very small effects, especially when learning effects are considered. LO 9.5

What is intelligence? Historical perspectives on intelligence: A single ability or general factor called “g” (Spearman) and specific abilities General intelligence refers to general differences in intelligence among people. Our specific skills are reflected in our specific abilities. 2. Multiple abilities (Thurstone and Guilford) 3. Single ability with two types of g, fluid and crystallized intelligence (Cattell) 4. Multiple abilities (Gardner and Sternberg) © John Wiley & Sons, Inc Huffman: Psychology in Action (8e)

The Impact Of Digital Media On Children’s Intelligence While Controlling For Genetic Differences In Cognition And Socioeconomic Background

Cattell and Horne theorize that “intelligence” is a mixture of two abilities: the ability to learn new ways of solving problems, or fluid intelligence, the accumulated knowledge about the world that we acquire over time, or crystallized intelligence.

Mathematical Intelligence Characteristics of High Scorers Using logical and mathematical skills Using logical and mathematical skills Spatial thinking and reasoning about objects in three-dimensional space Performing, understanding, and enjoying music Performing, understanding, and enjoying music Mathematical intelligence in sport, dance, or other physical activity Autistic sants argue that efforts support mutual understanding and effective communication with others Mutual understanding and insight about oneself Natural recognition, recognition and understanding of animals, plants and other living things A response to this model is that it is not clear why only certain abilities are classified as intelligence since it is almost impossible to be wrong, and there is no good evidence that these intelligences are truly independent.

Sternberg’s triarchic model hypothesizes three distinct types of intelligence. It is believed that having one does not ensure that you have the others Analytical intelligence is the ability to reason logically or “book smarts”. Practical intelligence is the ability to solve real-world problems, or “street smarts.” Creative intelligence is the ability to find new and effective solutions. It has several weaknesses: Practical intelligence is not independent of g. A causal relationship between job performance and practical intelligence is not clear. We all have strengths and weaknesses, but they may not be as different as theories. LO 9.1

The original version of the Stanford-Binet (IQ = MA/CA x 100) Stanford-Binet and Wechsler are commonly used personal intelligence tests. Both tests calculate an intelligence quotient (IQ), which compares the deviation of a person’s test score to norms for that person’s age, removing age effects. ©John Wiley & Sons, Inc.

13 IQ Test The most commonly used IQ test for adults today is the Wechsler Adult Intelligence Scale. Contains 15 subtests that yield 5 scores: General IQ Verbal Comprehension Perceptual Reasoning Working Memory Processing Speed

Three scientific criteria for psychological tests: Standardization — establishing uniform rules and procedures for giving and scoring tests Reliability — a measure of the stability and consistency of test scores over time Validity — the test’s ability to measure what it is designed to measure © John Wiley & Sons, Inc.

Testing A Cognitive Control Model Of Human Intelligence

In adults, scores are fairly stable over time. However, before the age of three, IQ tests are very inconsistent and are poor predictors of adult IQ. Validity IQ scores have been very successful in predicting grades, predicting performance in a wide variety of occupations, and are associated with health-related outcomes (health literacy) with relationships consistent despite taking social class into account. LO 9.5

Intellectual disability: 70 and below Mental giftedness: IQs of 135 and above © John Wiley & Sons, Inc Huffman: Psychology in Action (8e)

A low IQ (less than about 70) that begins in childhood and affects 1 percent of the US population (mostly men) has four levels: mild, moderate, severe, and profound PO is a more severe intellectual disability that is less likely to run in families. More than 200 different cases; The most common are Fragile X syndrome and Down syndrome.The actions of the ADA and IDEA have greatly affected the lives of people with intellectual disabilities. LO 9.6

Defining And Measuring Intelligence

The top 2 percent of IQ scores represent: doctors, lawyers, engineers, “termites” teachers, the vast majority occupy specific occupations. What makes a genius? Genetic factors play a role, but so does practice and dedication. Intellectual brilliance with little effort is very unrealistic. LO 9.6

Most research finds little or average differences between males and females. But, boys’ scores are more variable. Research shows consistent differences in specific mental abilities. Girls are better at some verbal tasks and at recognizing emotions in others. Men perform better on tests of spatial ability, such as mental rotation and geography. LO 9.9

Poverty and IQ (Environmental Effects) Jensen Study of Cumulative Deficit (progressive decline in IQ with age due to environmental/educational deprivation). Jensen: Verbal IQ is stronger than non-verbal IQ. Lack of proper nutrition and lead exposure lead to low IQs. Scientific debate about the effect of breastfeeding on IQ. Conflicting studies, but a recent review (2015) confirmed a positive effect. LO 9.8

Iq Tests Are ‘fundamentally Flawed’ And Using Them Alone To Measure Intelligence Is A ‘fallacy’, Study Finds

IM: Cultural Bias in IQ Activity Testing IM: Nature vs. Nurture Activity The Flynn Effect Average IQ in a population is increasing by 3 points every 10 years. The most likely outcome of environmental changes: the sophistication of testing the increased complexity of the modern world better nutrition changes at home and school

Behavioral Genetics Studies: Trying to Sort Out Genetic vs. Environmental Influences Family studies confirm that IQ runs in families. Siblings have an IQ of .5, cousins ​​at .15. Twin studies show identical twin correlations of .7–.8, sibling correlations of .3–.4. But high levels of environmental deprivation mask the effects of genes. ©John Wiley & Sons, Inc. Huffman: Psychology in Action (8e)

Brain volume is positively correlated with measured intelligence. But correlations of .3–.4 do not explain everything, and relationship may not be causal. Evidence suggests that cerebral cortex development is slower in gifted children. LO 9.2

Which “leg” in the picture is longer (a) or (b)? The time it takes people to make the right choice between rapidly flashing items like the one on this screen can reveal something about their intelligence. Intelligence reflects the ability of mental processing. People with high intelligence show faster reaction time. Working memory is also closely related to intelligence. ©John Wiley & Sons, Inc. Huffman: Psychology in Action (8e)

The prefrontal cortex is particularly active during most “G-loaded” tasks, but other parts of the brain are also important. A key point is that people who think quickly are smarter. LO 9.3

28 Creativity is often measured using different thinking tests, “outside the box” thinking test “using object” but we also need to be good at convergent thinking: finding the best personal solution to a problem. The relationship between creativity and bipolar disorder manic episodes was slightly correlated with IQ (.2–.3), but not quality. However, the best predictor of work quality is work quantity. Difficult to measure on an IQ test LO 9.11
