Question

A developmental psychologist wants to study the effects of poverty on one's self-concept. To do this, a group of subjects from the central city are interviewed once every five years over the period of 30 years. The same subjects are interviewed throughout the 30 years. This study is an example of what type of research?

a) Experimental Research
b) Correlational Research
c) Cross-Sectional Study
d) Longitudinal Study

Answer 1

The developmental psychologist's study on the effects of poverty on one's self-concept by interviewing subjects every five years for 30 years is an example of longitudinal research, tracking the same individuals across their lifespans.

Step-by-step explanation:

When a developmental psychologist conducts interviews of the same subjects every five years over a period of 30 years, this type of research is known as longitudinal research. This method allows for the observation of changes over time within the same group of individuals. The study mentioned does not manipulate variables as in an experimental study, nor does it simply look for correlations or take cross-sectional snapshots of different age groups at one point in time.

Instead, longitudinal studies track the same individuals across various points in their lifespans, making the data valuable for observing developmental changes and the effects of long-term influences such as poverty on self-concept.
