Exam 2: Theory and Method in Studying Aging and Older Adulthood

What does the lifespan developmental perspective propose about gains and losses over the life span?

In which kind of research studies are participants randomly assigned to levels of an independent variable?

Which metamodel views development as a progressive sequence of stages which are internally generated?

Which of the following is NOT an important aspect of the lifespan developmental perspective?

A researcher measures the amount of time older adults spend each week engaging in mentally challenging activities and also the scores they earn on a test of intelligence.The researcher finds that the more time older adults spend engaging in mentally challenging activities,the higher their scores on the intelligence test.On the basis of this finding,which of the following conclusions would the researcher be justified in drawing?

Which two factors are confounded (unable to be separated) when measures of computer attitudes made today on a sample of 70-year-olds today are compared with measures of computer attitudes made 10 years ago on a sample of 70-year-olds?

Professor Adams is interested in comparing the attitude today's 70-year-old adults have toward using computers with the attitude that 70-year-old adults had 10 years ago.Assuming that she has computer attitude measures from a group of 70-year-old adults taken this year and computer attitude measures from a group of 70-year-old adults made 10 years ago,which type of research design does Professor Adams have?

Which correlation shows the strongest association between two variables?

In which research design is attrition the most obvious issue to consider?

Being able to generalize the findings obtained from a sample of research participants to the population from which this sample was drawn refers to the ___________ of a research study.

Dr.Perkins places rats that always lived in a deprived environment into a new "enriched" environment with an exercise wheel and toys to stimulate the rats' problem-solving capabilities.After two weeks in the enriched environment,the rats seem more alert than they were before.Dr.Perkins decides to try the same thing with a new sample of rats,which also seem more alert after spending two weeks in the new environment.This means that Dr.Perkins replicated his findings on the second sample of rats.However,when Dr.Perkins wants to know whether the rats became more alert because of the exercise wheel or because of the toys,he is concerned with the issue of _____________.

Which metamodel views the organism and the environment as being in continuous interaction?

According to the organismic metamodel,__________________.

In studies with an extreme age groups design,________.

A developmental scientist with a mechanistic metamodel ______.

Compare the viewpoint of a behavioral scientist who approaches the study of behavior with mechanistic metamodel and the viewpoint of a scientist who approaches the study of behavior with an organismic metamodel.

The _______ of a study refers to whether there can be accurate identification and interpretation of the factor(s) responsible for an observation.

When a measurement instrument is reliable that means it is _________.

The longitudinal research design confounds (is unable to separate) ________.

What is meant by a descriptive approach to research and what role does correlation play?
