Time-Lag Comparison - ✔✔The study of developmental processes by
taking measures of children of the same age group at different times.
cross-sequential research - ✔✔An approach that combines the longitudinal
and cross-sectional methods by following individuals of different ages for
abbreviated periods of time.
Cohort effect - ✔✔Similarities in behavior among a group of peers that
stem from the fact that group members were born at the same time in
history.
Cross-sectional Research - ✔✔The study of developmental processes by
taking measures of participants of different age groups at the same time.
Longitudinal Research - ✔✔The study of developmental processes by
taking repeated measures of the same group of participants at various
stages of development.
, Experimental Group - ✔✔A group made up of subjects in an experiment
who do not receive the treatment but for whom all other conditions are
comparable to those of subjects in the experimental group.
Dependent Variable - ✔✔A measure of an assumed effect of an
independent variable.
Independent Variable - ✔✔A condition in a scientific study that is
manipulated so that its effects can be observed.
Hypothesis - ✔✔A proposition to be tested.
Experiment - ✔✔A method of scientific investigation that seeks to discover
cause- and-effect relationships by introducing independent variables and
observing their effects on dependent variables.
Negative Correlation - ✔✔A relationship between two variables in which
one variable increases and the other decreases.
Positive Correlation - ✔✔A relationship between two variables in which one
variable increases as the other increases.
Correlation Coefficient - ✔✔A number ranging from +1.00 to -1.00 that
