What is the experimental method of psychology?
The experimental method of psychology is a scientific method concerned with experimental procedure. This method states that variables, whether inde...
What is the main purpose of experimental research?
The main purpose of experimental research is to test a hypothesis. Once the hypothesis is tested, data can be analyzed and conclusions can be drawn.
What is experimental method?
An experiment is an investigation in which a hypothesis is scientifically tested.
What is a laboratory experiment?
A laboratory experiment is an experiment conducted under highly controlled conditions (not necessarily a laboratory), where accurate measurements are possible. The researcher decides where the experiment will take place, at what time, with which participants, in what circumstances and using a standardized procedure.
What is field experiment?
Field experiments are done in the everyday (i.e. real life) environment of the participants. The experimenter still manipulates the independent variable, but in a real-life setting (so cannot really control extraneous variables). An example is Holfing’s hospital study on obedience. Strength: behavior in a field experiment is more likely ...
What is random allocation?
The principle of random allocation is to avoid bias in the way the experiment is carried out and to limit the effects of participant variables.
What are the limitations of strength?
Limitation: They may be more expensive and time consuming than lab experiments. Limitation: There is no control over extraneous variables that might bias the results.
What is order effect?
Examples of order effects include: (i) practice effect: an improvement in performance on a task due to repetition , for example, because of familiarity with the task;
What are some examples of strength?
An example is Holfing’s hospital study on obedience. Strength: behavior in a field experiment is more likely to reflect real life because of its natural setting, i.e. higher ecological validity than a lab experiment. Strength: There is less likelihood of demand characteristics affecting the results, as participants may not know they are being ...
What is experimental testing?
The word “experimental” in this context means that tests are administered to participants, outcomes are measured, and comparisons are made. More formally, this means that a group of participants are exposed to a stimulus (or stimuli), and their behavior in response is recorded.

Wilhem Wundt is often credited with being “the father of experimental psychology” and is the founding point for many aspects of it. He began the first experimental psychology lab, scientific journal, and ultimately formalized the approach as a science. Wundt set in stone what Fechner had put on paper.
