OneClass has been such a huge help in my studies at UofT especially since I am a transfer student. OneClass is the study buddy I never had before and definitely gives me the extra push to get from a B to an A!

Balancing social life With academics can be difficult, that is why I'm so glad that OneClass is out there where I can find the top notes for all of my classes. Now I can be the all-star student I want to be.

Psych Chapter 10: Intelligence Intelligence is not something that has concrete existence, but instead a socially constructed concept Intelligence is the ability to acquire knowledge, to think and reason effectively, and to deal adaptively with the environment INTELLIGENCE IN HISTORICAL PERSPECTIVE Sir Francis Galton and Alfred Binet are 2 of the major contributors to the study of mental skills Sir Francis Galton: Quantifying Mental Ability Found that smart people often came from the same family BUT he dismissed that fact that the successful people he studied usually came from privileged environments (belief bias) Measured nervous system efficiency with a variety of tests (reaction speed, hand strength, sensory acuity, skull size, etc.) to try to demonstrate a biological basis for eminence by showing that successful (smarter) people would perform better on these tasks He was NOT successful in this Alfred Binets Mental Tasks Was commissioned to develop a modern intelligence test Made 2 assumptions about intelligence: 1) Mental abilities develop with age 2) The rate at which people gain mental competence is a characteristic of the person and is fairly constant over time The result of the testing was a score called a mental age this is the age that they perform at (ex. A 6 year old who could go math problems that a 10 year old can has a mental age of 10) Stern came along later and developed a relative score to compare peoples intelligence with different chronological ages This score was called IQ (intelligence quotient) It represented (mental age chronological age) x 100 So for example a child who is performing exactly at his age level should have a score of 100 Todays tests no longer use this mental age concept Mental age concept worked well for children but not for adults
