It is important to appreciate that the human brain is an extremely complicated piece of biological machinery. We will explore the role of brain structures in more detail as we discuss specific disorders later in this chapter. Cannot resist the urge to hurt themselves or others such as setting fires.

It looks at biological, psychological, and social factors to understand a person's behavior. as relates to diagnosing medical behavior, the position that there is no uinversal standard to measure cultures by, and that all cultures are equally valid and must be understood in their own terms. Cocaine. Harlow, J. M. (1848). Neurobiological aspects. BA25 acts as a "junction box" that interacts, through the use of neurotransmitters such as dopamine, with other areas of the brain involved in mood, emotion and thinking. The weakness of this approach is that it often fails to account for other influences on behavior. In terms of anxiety disorders, predispositions include aspects of biological and psychological. An anxiety disorder marked by unpredictable minutes-long episodes of intense dread in which a person experiences terror and accompanying chest pain, choking, or other frightening sensations. Biological psychology is also referred to as biopsychology, behavioral neuroscience or psychobiology. a mark of disgrace associated with a particular circumstance, quality, or person.

These structures include neurons, brain regions, neurotransmitters or genes. For example, we could ask how prescribed drugs to treat depression affect behavior through their interaction with the nervous system. Cocaine works by reducing the amount of monoamine neurotransmitters (dopamine, norepinephrine, epinephrine, and serotonin) that are taken back into the presynaptic neuron (Richards & Laurin, 2021), as shown in Figure 2. is an excitatory neurotransmitter in the amygdala and GABA is an inhibitory. 17: Biological Bases of Psychological Disorders, {

DSM-5 (Diagnostic and Statistical Manual of Mental Disorders). This branch of psychology has grown tremendously in recent years and is linked to other areas of science including biology, neurology, and genetics.The biological perspective is essentially a way of looking at human problems and actions. In J. Barkow, L. Cosmides, & J. Tooby (Eds. Biological psychology examines the relationship between mind and body, neural mechanisms, and the influence of heredity on behavior. In family and twin studies, schizophrenia is significantly more likely to be present in an identical twin than a fraternal twin (Coon & Miller, 2007) and in individuals with a first-degree relative (e.g. This is known as the diathesis-stress model of human behavior. When making a diagnosis of diabetes, a doctor may use a blood test to determine blood glucose levels. A limitation is that most biological explanations are reductionist, as it reduces behavior to the outcome of genes and other biological processes, neglecting the effects of childhood and our social and cultural environment. A psychological disorder is a condition characterized by abnormal thoughts, feelings, and behaviors. Monozygotic = identical twins (share 100% genetic information). Migrating animals stop to eat only the very least that . Furthermore, while researchers currently believe that genetic factors are implicated in all psychological disorders, they are not believed to be the sole cause. the prevailing idea is the neurodevelopment theory-that is due to abnormalities with pre- or neonatal development of the nervous system. Today, psychosurgery is rarely used, and when it is used, it is done in a more precise way than before. Biopsychologists study many of the same things that other psychologists do, but they are interested in looking at how biological forces shape human behaviors. There are many factors that contribute to mental disorders. Comparative method: By studying different animal species, their behavior under similar stimuli can be compared to human data enhancing the understanding of human behaviors. Comparative method: different species of animal can be studied and compared. A strength of the biological approach is that it provides clear predictions, for example, about the effects of neurotransmitters, or the behaviors of people who are genetically related. However, exactly how these factors interact with one another to produce a particular psychological disorder is still unclear. The biological model of psychology treats psychological abnormalities as a physical illness. Twins are concordant for a trait if both or neither of the twins exhibits the trait. Dizygotic = non-identical twins (share 50% genetic information, similar to siblings). One of these calcium channel genes, CACNA1C, is known to affect the brain circuitry involved in emotion, thinking, attention and memory. Antipsychotics help people like Vince, who suffer from hallucinations and delusions. The biological perspective is a way of looking at psychological issues by studying the physical basis for animal and human behavior. Results for 'Biological Psychology' 1000+ found. include a decrease in emotional expression, lack of interest in social activities. Boston, MA: Cengage Learning; 2015.

A dissociative identity disorder (formerly, multiple personality disorder) is characterized by the assuming of two or more distinct, integrated personalities, each of which manifests itself at times. Patients like Vince aren't the only ones who can benefit from psychotropic medication. The hypothalamus dysfunction theory would suggest that animals have . The stimulation of central beta receptors and the blockade of alpha-2 receptors also produce . Each of these biological aspects, the comparative, the physiological (i.e., the brain) and the genetic, can help explain human behavior.if(typeof ez_ad_units!='undefined'){ez_ad_units.push([[580,400],'simplypsychology_org-medrectangle-3','ezslot_5',615,'0','0'])};__ez_fad_position('div-gpt-ad-simplypsychology_org-medrectangle-3-0'); Twin studies provide geneticists with a kind of natural experiment in which the behavioral likeness of identical twins (whose genetic relatedness is 1.0) can be compared with the resemblance of dizygotic twins (whose genetic relatedness is 0.5). (Formally referred to as hysteria), involves difficulties in controlling urges to perform certain behaviors. ECT is still not commonly used, but it can work well for people with severe depression or bipolar disorder, or catatonic patients.

Biological psychology, also called physiological psychology, is the study of the biology of behavior; it focuses on the nervous system, hormones and genetics. The American Psychological Association periodically updates the Diagnostic and Statistical Manual of Mental Disorders - also called the DSM - so that it will accurately reflect our current understanding of the symptoms, etiology, and treatment of psychological disorders. The biological perspective is relevant to psychology through three areas of investigation. Biological research has helped yield useful treatments for a variety of psychological disorders.

From the perspective of a psychologist, depression is due to a chemical imbalance in the brain. In humans with the genetic predisposition for an eating disorder, it is weight loss that triggers the eating disorder. Lobotomies, a specific type of psychosurgery that involves removing the prefrontal cortex of the brain, were sadly too common in the mid-twentieth century. Researchers in this field examine how biology, particularly the . a sort of interview in which the clinician spends time talking with the individual and asking the patient some questions.
