Psychophysiology (from Greek Ancient Greek is the historical stage in the development of the Greek language spanning the Archaic , Classical (c. 5th–4th centuries BC), and Hellenistic (c. 3rd century BC – 6th century AD) periods of ancient Greece and the ancient world. It is predated in the 2nd millennium BC by Mycenaean Greek. Its Hellenistic phase is known as Koine (& ψῡχή, psȳkhē, "breath, life, soul"; φύσις, physis, "nature, origin"; and -λογία, -logia) is the branch of psychology Psychology is the scientific study of human or other animal mental functions and behaviors. In this field, a professional practitioner or researcher is called a psychologist. Psychologists are classified as social or behavioral scientists. Psychological research can be considered either basic or applied. Psychologists attempt to understand the that is concerned with the physiological Physiology is the science of the functioning of living systems. It is a subcategory of biology. In physiology, the scientific method is applied to determine how organisms, organ systems, organs, cells and biomolecules carry out the chemical or physical function that they have in a living system. The word physiology is from Ancient Greek: φύσις bases of psychological Psychology is the scientific study of human or other animal mental functions and behaviors. In this field, a professional practitioner or researcher is called a psychologist. Psychologists are classified as social or behavioral scientists. Psychological research can be considered either basic or applied. Psychologists attempt to understand the processes.[1] While psychophysiology was a general broad field of research in the 1960s and 1970s, it has now become quite specialized, and has branced into subspecializations. For example, Social Psychophysiology, Cardiovascular Psychophysiology, Cognitive Psychophysiology, and Cognitive Neuroscience.
Some people have difficulty distinguishing a psychophysiologist from a physiological psychologist, two very different perspectives. Psychologists are interested in why we may fear spiders Spiders are air-breathing arthropods that have eight legs, and chelicerae with fangs that inject venom. They are the largest order of arachnids and rank seventh in total species diversity among all other groups of organisms. Spiders are found worldwide on every continent except for Antarctica, and have become established in nearly every habitat and physiologists may be interested in the input/output system of the amygdala The amygdalae are almond-shaped groups of nuclei located deep within the medial temporal lobes of the brain in complex vertebrates, including humans. Shown in research to perform a primary role in the processing and memory of emotional reactions, the amygdalae are considered part of the limbic system.. A psychophysiologist will attempt to link the two. Psychophysiologists almost always study the psychological/physiological link in intact human subjects. While early psychophysiologists almost always examined the impact of psychological states on physiological system responses, since the 1970s, psychophysiologists also frequently study the impact of physiological states and systems on psychological states and processes. It is this perspective of studying the interface of mind and body that makes psychophysiologists most distinct.
Historically, most psychophysiologists tended to examine the physiological responses and organ systems innervated by the autonomic nervous system. More recently, psychophysiologists have been equally, or potentially more, interested in the central nervous system, exploring cortical brain potentials such as the many types of event-related potentials An event-related potential is any measured brain response that is directly the result of a thought or perception. More formally, it is any stereotyped electrophysiological response to an internal or external stimulus (ERPs), brain waves, and utilizing the advance technology of functional magnetic resonance imaging (fMRI), MRI, PET, MEG, and other neuroimagery techniques.
Continuing the comparison between a psychophysiologist and a physiological psychologist, a psychophysiologist may look at how exposure to a stressful situation will produce a result in the cardiovascular system such as a change in heart rate (HR), vasodilation/vasoconstriction, myocardial contractility, or stroke volume. A physiological psychologist may look at how one cardiovascular event may influence another cardiovascular or endocrine event, or how activation of one neural brain structure exerts excitatory activity in another neural structure which then induces an inhibitory effect in some other system. Often, physiological psychologists examine the effects that they study in infrahuman subjects using surgical or invasive techniques and processes.
Psychophysiology is closely related to the field of Neuroscience and Social neuroscience Social neuroscience is an interdisciplinary field devoted to understanding how biological systems implement social processes and behavior, and to using biological concepts and methods to inform and refine theories of social processes and behavior. Humans are fundamentally a social species, rather than individualists. As a social species, Homo, which primarily concerns itself with relationships between psychological Psychology is the scientific study of human or other animal mental functions and behaviors. In this field, a professional practitioner or researcher is called a psychologist. Psychologists are classified as social or behavioral scientists. Psychological research can be considered either basic or applied. Psychologists attempt to understand the events and brain The brain is the center of the nervous system in all vertebrate, and most invertebrate, animals. Some primitive animals such as jellyfish and starfish have a decentralized nervous system without a brain, while sponges lack any nervous system at all. In vertebrates, the brain is located in the head, protected by the skull and close to the primary responses. Psychophysiology is also related to the medical discipline known as psychosomatics.
While psychophysiology was a discipline off the mainstream of psychological and medical science prior to roughly the 1960 and 1970s, more recently, psychophysiology has found itself positioned at the intersection of psychological and medical science, and its popularity and importance have expanded commensurately with the realization of the inter-relatedness of mind and body.

Commonly used measures
Many measures are part of modern psychophysiology including measures of brain activity such as ERPs, brain waves (electroencephalography, EEG), fMRI Functional MRI or functional Magnetic Resonance Imaging is a type of specialized MRI scan. It measures the hemodynamic response (change in blood flow) related to neural activity in the brain or spinal cord of humans or other animals. It is one of the most recently developed forms of neuroimaging. Since the early 1990s, fMRI has come to dominate (functional magnetic resonance imaging), measures of skin conductance (skin conductance response, SCR; galvanic skin response Galvanic skin response , also known as electrodermal response (EDR), psychogalvanic reflex (PGR), or skin conductance response (SCR), is a method of measuring the electrical resistance of the skin. There has been a long history of electrodermal activity research, most of it dealing with spontaneous fluctuations, GSR), cardiovascular measures (heart rate Heart rate is the number of heartbeats per unit of time - typically expressed as beats per minute - which can vary as the body's need for oxygen changes, such as during exercise or sleep. The measurement of heart rate is used by medical professionals to assist in the diagnosis and tracking of medical conditions. It is also used by individuals,, HR; beats per minute In musical terminology, tempo is the speed or pace of a given piece. It is a crucial element of composition, as it can affect the mood and difficulty of a piece, BPM; heart rate variability, HRV; vasomotor activity), muscle activity (electromyography Electromyography is a technique for evaluating and recording the electrical activity produced by skeletal muscles. EMG is performed using an instrument called an electromyograph, to produce a record called an electromyogram. An electromyograph detects the electrical potential generated by muscle cells when these cells are electrically or, EMG), changes in pupil diameter with thought and emotion (pupillometry) and eye movements, recorded via the electro-oculogram (EOG) and direction-of-gaze methods.
Uses of psychophysiology
Psychophysiological measures are often used to study emotion and attention responses to stimuli, during exertion,and increasingly, to better understand cognitive processes.

Q. I'm working on a Psychology paper in the more specific area of Psychophysiology. An article that I'm working with discusses frequencies when talking about heart rate, and I don't really know what it's referring to. I can bluff, but I'd rather know. Can someone please enlighten me? Here's part of what the article says: "The energy in the HRV series in the following specific frequency bands was studied: the very low frequency band (0.0-0.05 Hz), low frequency band (0.05-0.15 Hz), and high frequency band (0.15-0.50 Hz)." HRV is heart rate variability. And why would someone look at these frequencies?

A. Researchers study how music therapy reduces risk factors for heart disease stress in Hispanic women Whether it s time alone with a good book or a trip to the salon, many women develop personal relaxation routines to cope with the stresses related to work, family and children. but for many women of color, coping is not always easy. Women of color are more likely to suffer from stress-related heart illness than their counterparts. And, for Hispanic women, the combination of high stress, lack of social support and a genetic predisposition to cardiac-related illness can be deadly. In an attempt to help Latinas improve their cardiovascular health, School of Medicine Professor Ellen Tedaldi, Associate Dean Sally Rosen and Boyer… [cont.]
