Biological psychology research methods

Likewise, the injection of 2-deoxyglucose prior to some behavioral task can be followed by anatomical localization of that chemical; it is taken up by neurons that are electrically active.

A system for taking information in one form and transforming it into another. The researchers went on to replicate findings in a subsequent experiment that involved balancing on a stabilometer.

During this, our brain waves begin to resemble those of our waking state though we are still fast asleep and it seems that this is when we dream whether we remember it or not. A biological perspective is relevant to the study of psychology in three ways: 1.

Like QTL mapping and selective breeding, genetic engineering is most commonly performed in mice.

Biological approach strengths and weaknesses

Biological psychology as a scientific discipline emerged from a variety of scientific and philosophical traditions in the 18th and 19th centuries. Lesions Lesions is a classic method in which a brain-region of interest is enabled. References Bain Alexander. Therefore, all that is psychological is first physiological. Psychopharmacological manipulations A chemical receptor agonist facilitates neural activity by enhancing or replacing endogenous neurotransmitters. When you return to the classroom, have each group member write down what they saw, felt, heard, tasted, and smelled. Temporal lobe: also known as the auditory cortex, this portion of the brain is involved in the interpretation of the sounds and language we hear. This can help in the search to understand human behavior. Transaction Publishers, The nature-nurture debate highlights a key argument in psychology, over the relative influence of biology and environment on the characteristics of an individual; an extreme biological approach assumes that these are determined solely by nature.

In functionalism, the brain is believed to have evolved for the purpose of bettering the survival of its carrier by acting as an information processor. In this chapter, we extend this discussion to include the theoretical and methodological aspects of these two approaches within the biological perspective and provide examples of relevant studies.

Doing Time: Prison experience and identity.

A History of Modern Psychology. Descartes, for example, suggested that the pineal glanda midline unpaired structure in the brain of many organisms, was the point of contact between mind and body. What the scan, therefore, enables researchers to do is to provide ongoing pictures of the brain as it engages in mental activity.

Even more sophisticated is the PET scan Positron Emission Tomography which uses a radioactive marker as a way of studying the brain at work. Anxiety, a physiological state characterized by cognitive, somatic, emotional, and behavioral components.

biological psychology examples

Cognitive psychologists rely on the functionalist insights in discussing how affect, or emotion, and environment or events interact and result in specific perceptions.
