Science is the…
systematic pursuit of knowledge through observation.
The first step of science is to define a _______________ and related ______________. A good theory is precise and could be disproven.
theory, hypotheses
A good theory can be proven.
False
Elements of science:
______________: the practice of relying on systemic observation
_______________: Scientific findings presented to community for scrutiny
_______________: deals with specifiable problems
Empiricism, Public Knowledge, Solvable
The _________________, perhaps the most familiar method of observing human behavior, involves recording detailed information about one person at a time.
case study
This statistic may take any value between −1.00 and +1.00, and it measures both the magnitude and the direction of a relationship.
correlation coefficient
______________________ is defined by whether a relationship between variables is large enough to matter.
Clinical significance
Longitudinal design
Investigation that collects information on the same individuals repeatedly over time, perhaps over many years, in an effort to determine how phenomena change.
cross-sectional design
in which the researcher measures the causes and effects at the same point in time.
The _________________ overcomes this problem; with this approach, researchers study only people with above-average risk of developing schizophrenia.
high-risk method
Even if a longitudinal study identifies a variable that precedes schizophrenia, a researcher still faces the _________________
third-variable problem
________________ is the study of the distribution of disorders in a population.
Epidemiology
Epidemiologic research focuses on three features of a disorder:
____________: The proportion of people with the disorder either currently or during their lifetime
____________: The proportion of people who develop new cases of the disorder in some period, usually a year
____________: Variables that are correlated with the presence of the disorder
Prevalence, Incidence, Correlates
When relatives are matched on presence or absence of a disorder, they are said to be ____________
concordant
The starting point in such investigations is the recruitment of a sample of persons with the diagnosis in question. These people are referred to as _______________ or _______________.
index cases, probands
adoptees method
studies children who were adopted and reared completely apart from their biological parents
