Originally a development of humanistic psychologists ' research on happiness and their focus on treating mental health rather than mental illness it is intended to complement, not to replace, traditional psychology.
Saul McLeodupdated The biological approach believes us to be as a consequence of our genetics and physiology. It is the only approach in psychology that examines thoughts, feelings, and behaviors from a biological and thus physical point of view.
Therefore, all that is psychological is first physiological. A biological perspective is relevant to the study of psychology in three ways: This can help in the search to understand human behavior.
For example, we could ask how prescribed drugs to treat depression affect behavior through their interaction with the nervous system. For example, we might want to know whether high intelligence is inherited from one generation to the next.
Each of these biological aspects, the comparative, the physiological i.
Investigation of Inheritance Twin studies provide geneticists with a kind of natural experiment in which the behavioral likeness of identical twins whose genetic relatedness is 1.
In other words, if heredity i. There are two types of twins: Research using twin studies looks for the degree of concordance or similarity between identical and fraternal i. Twins are concordant for a trait if both or neither of the twins exhibits the trait.
Twins are said to be disconcordant for a trait if one shows it, and the other does not. Identical twins have the same genetic make-up, and fraternal twins have just 50 per cent of genes in common.
Thus, if concordance rates which can range from 0 to are significantly higher for identical twins than for fraternal twins, then this is evidence that genetics play an important role in the expression of that particular behavior.
Bouchard and McGue conducted a review of worldwide studies which compared the IQ of family members. The correlation figures below represent the average degree of similarity between the two people the higher the similarity, the more similar the IQ scores.
For example, Bouchard and McGue included many poorly performed and biased studies in their meta-analysis. Also, studies comparing the behavior of twin raised apart have been criticized as the twins often share similar environments and are sometimes raised by non-parental family member.
Methods of Studying the Brain It is important to appreciate that the human brain is an extremely complicated piece of biological machinery.
The brain can influence many types of behavior.
In addition to studying brain damaged patients, we can find out about the working of the brain in three other ways. Children begin to plan activities, make up games, and initiate activities with others. If given this opportunity, children develop a sense of initiative and feel secure in their ability to lead others and make decisions.
Neuro Surgery We know so little about the brain and its functions are so closely integrated that brain surgery is usually only attempted as a last resort. This technique cured his epilepsy, but in the process the hippocampus had to be removed this is part of the limbic system in the middle of the brain.- Blushing and Physiological Arousability in Social Phobia Introduction This paper will provide a critique of the article titled “Blushing and Physiological Arousability in Social Phobia,” (Gerlach et al., ) located in the Journal of Abnormal Psychology (Vol.
, No. 2). This invited book chapter addresses ways in which Yogic (and related) principles and practices can be introduced more fully into psychological research, in order to allow that research—and psychology itself—to be more inclusive, integrated, and relevant to human psychospiritual concerns.
Physiological psychology is the scientific study of the biological factors which underlie human behavior. Various other branches of psychology are primarily concerned with how social, economic, and cultural factors affect human emotions, behaviors, and development.
Charles Darwin was born in , seven years after his grandfather Erasmus had died. Charles grew up during a conservative period in British and American society, shortly after the Napoleonic Wars. Biopsychology is the subarea of psychology that takes a biological approach to understanding behavior.
Biopsychologists study the biological events - genetic, neural, endocrine- that underlie each and every one of our thoughts, feelings, and actions. The Importance . Assessment is a critical piece of the learning process. This lesson gives an overview of assessment, why it benefits both teachers and students, and the three most common forms of assessment.
