Exam Revision Flashcards
What is the conceptual definition of intelligence?
The ability to learn from experience, solve problems and use knowledge to adapt to new situations.
What are the 3 characteristics of intelligence?
- Abstract thinking/reasoning abilities
- Problem-solving abilities
- Capacity to acquire knowledge
Outline Simon and Binet’s contributions to intelligence.
- Aimed to identify children who needed help at school
- Assumed that intelligence underlies reasoning, thinking and problem solving
- Developed a set of age-graded intellectual tasks in which mental age was compared to chronological age
Outline Goddard’s contributions to intelligence.
- Took Binet’s test to US to identify mentally retarded children
- Viewed intelligence as a fixed entity
- Argued that feeblemindedness ran in families
- Used test to screen potential immigrants
Outline Terman’s contributions to intelligence.
- Developed Stanford-Binet scale
- IQ = (MA / CA) x 100, where 100 is normal intelligence
- Used currently (SB5), measuring fluid reasoning, knowledge, quantitative reasoning, visual-spatial processing and working memory
How is IQ now calculated?
In relation to norms of performance of other individuals of the same age.
Outline Wechsler’s contributions to intelligence.
- Believed intelligence was the global capacity of a person to act purposefully, think rationally and deal effectively with their environment
- Designed Wechsler tests
- Improved old tests by including both verbal and non-verbal subtests, placing less emphasis on cultural knowledge and being more specific, with subtests scored separately
What does WAIS-IV give scores for?
- Overall IQ
- Verbal comprehension index (VCI)
- Perceptual reasoning index (PRI)
- Working memory index (WMI)
- Processing speed index (PSI)
What does WISC-V give scores for?
- Overall IQ
- Verbal comprehension
- Visual-spatial abilities
- Fluid reasoning
- Working memory
- Processing speed
Discuss the reliability and validity of IQ tests.
- Reliability is not good before age 7 but consistent for teenagers and adults
- Good validity when predicting school or occupational success, but should not be used to predict irregular areas
What other factors need to be taken into account when considering scores from IQ tests?
- Cultural factors
- Context, for example: anxiety, fatigue, testing environment, etc.
What is eugenics?
The idea that children with lower IQs are genetically inferior, and that the human race can be improved by discouraging such people from reproducing.
What is psychometrics & the psychometric approach?
The study of psychological tests. The psychometric approach to intelligence aims to identify and measure the abilities that underlie individual difference in performance.
What is the Flynn effect?
The notable rise in intelligence test scores over the past century.
Name and describe the two biases in intelligence testing?
- Outcome bias (the extent to which a test underestimates a person’s true intellectual ability)
- Predictive bias (where the test successfully predicts criterion measures for some groups but not others)
What is the current view of the causes of intelligence?
Nature and nurture both influence intelligence, however genetics seems to have a slightly bigger influence. The current idea is that genetics sets out a person’s capacity, and their environment determines whether or not they achieve their potential.
Describe the Kaler and Freeman study.
Kaler and Freeman studied the development of Romanian orphans aged between 23 and 50 months. Apgar scores indicated normal intelligence at birth, however they found that orphans with minimal human interactions showed severely delayed development, particularly in interaction, play, requesting, self-recognition and social reference.
Describe Spearman’s theory of intelligence.
- An individual’s performance at one type of cognitive task tends to be positively correlated with their performance at other cognitive tasks
- Suggested these correlations reflected the influence of an underlying general mental ability (g-factor)
- Believed that there were also specific abilities (mechanical, spatial, numerical and verbal)
- Theory based on the idea that g-factor drives performance but it is distributed unevenly among the specific abilities for different people.
Describe Thurstone’s theory of intelligence.
Psychometric approach that suggests 7 primary mental abilities:
- Numerical
- Reasoning
- Verbal functioning
- Spatial visualisation
- Perceptual ability
- Memory
- Verbal comprehension
Describe Cattell’s theory of intelligence.
Believed there are two types of intelligence:
- Fluid (Gf), which is the capacity to think logically and solve new problems
- Crystallised (Gc), which is previously acquired knowledge and the ability to use it
Suggested there are 7 underlying smaller factors:
- Short-term memory
- Long-term memory
- Visual processing
- Auditory processing
- Simple processing speed
- Complex processing speed
- Mathematical
Outline Gardner’s theory of intelligence.
Differentiates intelligence into 9 various modalities:
- Linguistic/verbal
- Logical/mathematical
- Spatial
- Musical
- Body/kinaesthetic
- Intrapersonal
- Interpersonal
- Naturalistic
- Spiritual/existential
What factors reflect intellectual disability?
Usually reflected by an IQ below 70. Severity is measured according to adaptive functioning requiring support in at least one of:
- Conceptual (academic)
- Social
- Practical
What are the typical signs of intellectual disability?
- Slow performance of mental operations
- Smaller knowledge base
- Do not remember to use certain mental strategies even if they know how to
What are the causes of intellectual disability?
Almost always biological factors, however can be environmental (eg: foetal alcohol syndrome).
What is specific learning disorder?
Difficulties learning and using academic skills despite intervention targeting these difficulties.
What are 4 purposes of intelligence testing?
- Answering referral questions
- Funding decisions
- Profile of strengths and weaknesses
- Predicting real world behaviours/performance (eg: academic success)
What are the 12 subtests in WISC-R
- Information
- Picture completion
- Similarities
- Picture arrangement
- Arithmetic
- Block design
- Vocabulary
- Object assembly
- Comprehension
- Coding
- Digital span
- Mazes
What is the difference between entity and incremental perspective views of intelligence?
Entity perspective views intelligence as fixed, while incremental perspective views intelligence as malleable.
What are the advantages of administering IQ tests in schools?
- Aid in decision making regarding the student (accelerated learning, etc.)
- Insight into academic problems
- Profile of student abilities
What are the disadvantages of administering IQ tests in schools?
- Labelling
- Teacher expectancy
- Time and cost heavy
- Stressful for students
Describe culture-fair tests.
Many tests assess learned information that is culture-specific, however culture-fair tests take cultural variables out. The problems with culture-fair tests include:
- Tests like WISC assess abilities that are important for success within a certain culture/society
- Removing influence of cultural variables renders tests less useful in predicting future performance in important domains
- Intelligence definitions vary according to attributes that enable success within a culture, and to be worthwhile, IW testing often needs to be culturally specific
What is psychopathology?
Problematic patterns of thought, feeling or behaviour that disrupt an individual’s sense of wellbeing or social or occupational functioning.
What are the 3 criteria for a disorder?
1: Deviance
- unusual compared to most
- statistical infrequency
- failure to conform to societal norms
2: Distress
- personal suffering
3: Dysfunction
- significantly impairs ability to function in everyday life
- failure to meet responsibilities
What is DSM-5?
A comprehensive diagnostic criteria which includes 20 major classes of > 300 disorders.
What are the advantages of psychological disorder diagnosis?
- Assist in treatment planning
- Facilitate research
- Facilitate communication between professionals
- Predicts behaviour and treatment response
What are the main criticisms of DSM-5?
- Labelling
- Stigmatising
- Comorbidity
- Categorical
In a conceptualisation of a client, what is it important to be aware of?
- Personal circumstances
- Medical problems
- Social/environmental problems
- Overall functioning
What are the 6 causes of psychological disorders?
- Biological
- Psychodynamic
- Cognitive
- Behavioural
- Humanistic
- Sociocultural
Explain the Diathesis-Stress Model.
Each individual, through a combination of biological, psychological and sociocultural factors, have a predisposition to experiences psychological difficulties, and problems occur when the individual experiences stress.
Explain anxiety disorders.
Where a client experiences excessive, persistent anxiety in (or in anticipation of) specific, non-threatening situations. This perception of danger results in a maladaptive act of trying to avoid it, which in turn negatively reinforces the avoidance.
What are the symptoms of anxiety disorder?
Symptoms can fall under the categories of cognitive (eg: worried thoughts), physiological (eg: increased heart rate), emotional (eg: fear) or behavioural (eg: avoidance)
What is agoraphobia?
Excessive fear of situations where escape would be difficult.
What is social phobia?
Fear of social situations in which the person would be negatively evaluated by others.
