CHILD DEVELOPMENT PEDAGOGY

Detailed explanation-1: -The Flynn effect refers to the consistent upward drift in IQ test scores across generations which has been documented to be approximately 3 points per decade.

Detailed explanation-2: -The Flynn effect refers to a secular increase in population intelligence quotient (IQ) observed throughout the 20th century (1–4). The changes were rapid, with measured intelligence typically increasing around three IQ points per decade.

Detailed explanation-3: -The “Flynn effect” refers to the observed rise over time in standardized intelligence test scores, documented by Flynn (1984a) in a study on intelligence quotient (IQ) score gains in the standardization samples of successive versions of Stanford-Binet and Wechsler intelligence tests.

Detailed explanation-4: -An example of the Flynn Effect is in intelligence scores. It is thought that if a person took an IQ test in the 19th Century, the average score would be significantly lower than it would be if that same person took an IQ test today.

Detailed explanation-5: -The correct answer is d) The observation that the mean standardized IQ score has risen since 1932. The Flynn Effect demonstrates that the average of the IQ scores will change as varying generations have different thresholds for what intelligence is necessary.
