Individual Differences
-Key Theme 1= understanding disorders
-Key Theme 2= measuring differences
Assumptions:
- To understand the human mind and behaviour we must focus on the diffs between people rather than what we have in common.
- These individuals diffs can be measures e.g. through psychometric tests
- Ech persons behaviour is due to; genetics, social experiences and personal qualities.
+= Practical applications as findings are used by psychiatry in modern day, Often contain case studies that are rich in detail and allow researchers in the future to further develop/invetigate the topic
-= Methodology may not be objective and be open to bias e.g. Freud, Unfalsifiable as concepts are usually difficult to test and measure
Gould (1982)
-Background:
- Yerkes wanted psychology to be considered a science
- Hereditarians hold a belief that heredity is more important than factors such as the env in determining intelligence
- 'Eugenics'= breeding 'superior' group of people
-Aim:
- Aim of Gould's article was to reveal the basic problems in attempts to measure intelligence
- Aim of Yerkes study= devise a scientific way to test the natural trait of intelligence on a mass scale
-Design:
- Yerkes- large scale psychometric testing
-Sample:
- 1.75 million army recruits situated in training camps.
- This would've included adult men of diff ages and men from a range of backgrounds and regions across the USA
-Procedure:
- Army Alpha- written test for literate recruits, 8 sections such as filling in missing numbers in sequence, reordering words in sentence and completing analogies.
- Army Beta- pictorial test for men who were illiterate or who failed the Army Alpha. 7 parts e.g, maze, number tasks, complete picture tasks.
- Individual Examination- individually spoken test for ps who had failed Army Beta
- Army psychologists would give a grade to each man, ranging from A-E (with + and -). Yerkes suggested C-= classed as low average intelligence and best suited as ordinary private. Men getting D grade = 'rarely suited for tasks requiring special skills'
-Gould's identified problems with the tests:
- Rushed/intimidating conditions
- Qs relting on cultural knowledge and access to formal schooling
- Discrimination in recall to Beta tests
- Inconsistances between camps
-Yerkes results:
- Average mental age of a white American man is around 13 years old
- Black Americans had a mean mental age of 10.4 years
- Northern and Western Europeans scored higher than Eastern and Southern Europeans= the average man of many countires would be classes as a moron
-Yerkes conclusions:
- Intelligence is an innate quality with a hereditary basis. It is possible to grade individuals by the colour of their skin
- The average man of many nations could be considered a 'moron'
- Mental testing of this kind is a valid, scientific technique with wider implications for society
-Gould's Conclusion:
- The Army mental tests were a product of their time and the results were used to further support racist beliefs and practices.
-Internal v
- Tests were more likely to measure things such as schooling or how long they had been in the country
- Beta test problems- still required the use of a pencil and…
