What Is Psychophysiology?

Psychophysiology (psychophysiology) is an interdisciplinary subject of psychology and physiology. Investigate the effects of psychological activities on physiological activities and related psychosomatic problems. The most basic problem of his research is the psychosomatic relationship. The main research contents are: psychophysiological problems of stress, polyspectral polygraph, and the relationship between workload and psychological load. The research method used manipulating the psychological activity of the subjects as independent variables, often applying different forms of psychological load, and observing or recording the changes of the dependent variables such as heart rate, blood pressure, respiration, skin electrical activity and EEG activity. ^[1]

Psychophysiology

Psychological processes related to the branch of psychology with physiological bases. It was once known as cognitive psychophysiology until the mid-1990s and is currently called cognitive neuroscience . For example, psychologists are interested in why we might be afraid of spiders and physiologists may be interested in input-output systems. Almond trees. Physiological psychologists will attempt to connect the two. He may, for example, try to explain arachnophobia's urge to come in and out of almond trees. However, physiological psychologists almost always learn psychological or physiological links in intact human subjects. When early physiological psychologists also almost always examined the impact of psychological states on physiological systems, from the 1970s, physiological psychologists learned about physiological states and the impact of systems on psychological states. It is a perspective that learns to make the physical and mental interface of physiological psychologists most distinct.

Psychophysiology is different from physiological physiology and psychophysiology looks in the way psychological activity leads to physiological response, while physiological psychology looks at the physiological mechanism leading to psychological activity. Historically, most physiological psychologists have tended to examine physiological responses and organ systems being innervated by the autonomic nervous system. Recently, physiological psychologists are equally or potentially more interested in the central nervous system, exploring epidermal brain potential such as many types of event-related potential (ERPs), brain waves, functional neuroimaging (fMRI), pets, trillion Oh wait.

Physiological psychologists may see how exposure to a stressful situation in the cardiovascular system will lead to a result such as a change in heart rate (hours), vasodilation or vasoconstriction, myocardial contractility, or stroke volume. A physiological psychologist may see how one cardiovascular event may affect another cardiovascular or endocrine event, or how the activation of the brain structure of one nervous system in some other system then causes a forbidden effect on the other nervous system Structure exerts excitement. Often, physiological psychologists examine their role in learning about apes topics using surgical or invasive techniques and procedures.

Psychophysiology is closely related to the field of neuroscience, and social neuroscience and relationships are mainly related to psychological events and brain reactions between yourself. Psychophysiology is also related to medical disciplines known as psychosomatics.

When psychophysiology was the main subject of psychology and medicine before about 1960, and in the 1970s, recently, psychophysiology found itself at the intersection of psychology and medicine, and its popularity and importance expanded the equivalent of physical and mental interaction Relevance awareness.

Many measures are part of modern psychophysiology including brain activity measures such as ERPs, brain waves (electroencephalographs, EEG), fMRI (functional magnetic resonance imaging), skin conductivity (skin conductivity response, SCR measures; electrical skin response GSR ), Cardiovascular measures (hours of heart rate; lower BPM per minute; heart rate variability HRV; vasomotor activity), muscle activity (EMG on student diameter EMG), change of excitement and (pupil measurement ) And eye movements are recorded by electroplating oculogram (EOG) and directional gaze method.

Psychophysiology measures are commonly used to learn emotional and attentional responses in response to stimuli. Shock tones, emotionally charged pictures, videos, and present tasks, and psychophysiological measures are used to examine the response.
