What is a psychological perspective?
A psychological perspective is a school of thought or a philosophy which would guide someone’s interpretation of an individual’s behavior.
Which question is most important to Biopsychology?
We can then say that biopsychology is the combination of psychology and neuroscience. In that case, we can say that the most important question for biopsychology is “How does brain chemistry affect how we feel and act?”
What is the social psychological perspective?
Social psychologists believe that human behavior is determined by both a person’s characteristics and the social situation. They also believe that the social situation is frequently a stronger influence on behavior than are a person’s characteristics. Social psychology is largely the study of the social situation.

How do psychologists conduct research?
Psychologists use the scientific method to conduct their research. The scientific method is a standardized way of making observations, gathering data, forming theories, testing predictions, and interpreting results. Researchers make observations in order to describe and measure behavior.
How do you randomly allocate participants in psychology?
Random Allocation – One way to control for issues like this is to randomly allocate people to conditions. So we might have our 100 participants and randomly split them into two groups. For example, putting all the names into a hat then picking out one for group 1, one for group 2, one for group 1 and so on.
How do you randomly allocate participants?
The easiest method is simple randomization. If you assign subjects into two groups A and B, you assign subjects to each group purely randomly for every assignment. Even though this is the most basic way, if the total number of samples is small, sample numbers are likely to be assigned unequally.
What are order effects psychology?
Order effects refer to the order of the conditions having an effect on the participants’ behavior. Performance in the second condition may be better because the participants know what to do (i.e. practice effect). Or their performance might be worse in the second condition because they are tired (i.e., fatigue effect).
What is the order of effect?
Order effects are where the order of treatments in an experiment matter. In other words, placing the treatments in a different order alter the results.
How do you avoid order effects?
Carryover and interference effects can be reduced by increasing the amount of time between conditions. Researchers also reduce order effects by systematically varying the order of conditions so that each condition is presented equally often in each ordinal position. This procedure is known as counterbalancing.
What is a specific item effect?
specific item effects. the results of your study may be due to the materials you use and not the IV (materials→DV not IV→DV); could be a confounding variable. simple random sampling.
