Research Methods

Scientific method

Scientific method

Theory, Hypothesis, Collect data (do research), analysis, replication/corroboration

Naturalistic Observation Disadvantages

No controls, participants alter behavior

naturalistic observation advantages

not intrusive, provides new info

Surveys/self report inventories advantages

cheap and easy data collection, provides broad characteristics of groups

Surveys/self report inventories disadvantages

talk vs action, demand characteristics, social desirability, framing

Case Study advantages

observe rare/unethical events

Case study disadvantages

no control, labor intensive

Cross sectional study

a study in which people of different ages are compared with one another, it is shorter and the drop out rates are lower

Longitudinal studies

A research method that studies the same participants multiple times over a period of time, higher drop out rate, takes longer

IRB/IACUC approval

The IRB reviews research that involves human participants. Research involving animals must be reviewed by the Institutional Animal Care and Use Committee (IACUC) before it begins.

Informed consent

an ethical principle that research participants are told to enable them to choose whether they wish to participate

withdrawing at any time

an ethical principle for research participants that allows them to leave the experiment at any time

minimal stress

ethical principle that the study must be not harm the well being of the participant.

confidentiality assured

Identity of participant not revealed

debrief at end

An example of debriefing can be used during an experiment whereby the researchers had to use some form of deception for the purpose of the study. In this case, during the debriefing session, the researchers would explain why they used deception and explain the purpose of it.
