Psychophysiology

psychophysiology, psychophysiology disorder
Psychophysiology from Greek ψῡχή, psȳkhē, "breath, life, soul"; φύσις, physis, "nature, origin"; and -λογία, -logia is the branch of psychology that is concerned with the physiological bases of psychological processes1 While psychophysiology was a general broad field of research in the 1960s and 1970s, it has now become quite specialized, and has branched into subspecializations such as social psychophysiology, cardiovascular psychophysiology, cognitive psychophysiology, and cognitive neuroscience

Backgroundedit

Some people have difficulty distinguishing a psychophysiologist from a physiological psychologist, two very different perspectives Psychologists are interested in why we may fear spiders and physiologists may be interested in the input/output system of the amygdala A psychophysiologist will attempt to link the two Psychophysiologists generally 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 ERPs, brain waves, and utilizing advanced technology such as 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, which primarily concerns itself with relationships between psychological events and brain 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

Measuresedit

Psychophysiology measures exist in three domains; reports, readings, and behavior2 Evaluative reports involve participant introspection and self-ratings of internal psychological states or physiological sensations, such as self-report of arousal levels on the self-assessment manikin,3 or measures of interoceptive visceral awareness such as heartbeat detection4 Merits to self-report are an emphasis on accurately understand the participants’ subjective experience and understanding their perception; however, its pitfalls include the possibility of participants misunderstanding a scale or incorrectly recalling events5 Physiological responses also can be measured via instruments that read bodily events such as heart rate change, electrodermal activity EDA, muscle tension, and cardiac output Many indices are part of modern psychophysiology, including brain waves electroencephalography, EEG, fMRI functional magnetic resonance imaging, electrodermal activity a standardized term encompassing skin conductance response, SCR, and galvanic skin response, GSR, cardiovascular measures heart rate, HR; beats per minute, BPM; heart rate variability, HRV; vasomotor activity, muscle activity electromyography, EMG, electrogastrogram EGG changes in pupil diameter with thought and emotion pupillometry, eye movements, recorded via the electro-oculogram EOG and direction-of-gaze methods, and cardiodynamics, recorded via impedance cardiography These measures are beneficial because they provide accurate and perceiver-independent objective data recorded by machinery2 The downsides, however, are that any physical activity or motion can alter responses, and basal levels of arousal and responsiveness can differ among individuals and even between situations6

Finally, one can measure overt action or behavior, which involves the observation and recording actual actions, such as running, freezing, eye movement, and facial expression These are good response measures and easy to record in animals, but they are not as frequently used in human studies2

Usesedit

Psychophysiological measures are often used to study emotion and attention responses to stimuli, during exertion, and increasingly, to better understand cognitive processes Physiological sensors have been used to detect emotions in schools7 and intelligent tutoring systems8

Emotionedit

It has long been recognized that emotional episodes are partly constituted by physiological responses9 Early work done linking emotions to psychophysiology started with research on mapping consistent autonomic nervous system ANS responses to discrete emotional states For example, anger might be constituted by a certain set of physiological responses, such as increased cardiac output and high diastolic blood pressure, which would allow us to better understand patterns and predict emotional responses Some studies were able to detect consistent patterns of ANS responses that corresponded to specific emotions under certain contexts, like an early study by Paul Ekman and colleagues in 1983 “Emotion-specific activity in the autonomic nervous system was generated by constructing facial prototypes of emotion muscle by muscle and by reliving past emotional experiences The autonomic activity produced distinguished not only between positive and negative emotions, but also among negative emotions”10 However, as more studies were conducted, more variability was found in ANS responses to discrete emotion inductions, not only among individuals but also over time in the same individuals, and greatly between social groups11 Some of these differences can be attributed to variables like induction technique, context of the study, or classification of stimuli, which can alter a perceived scenario or emotional response However it was also found that features of the participant could also alter ANS responses Factors such as basal level of arousal at the time of experimentation or between test recovery, learned or conditioned responses to certain stimuli, range and maximal level of effect of ANS action, and individual attentiveness can all alter physiological responses in a lab setting12 Even supposedly discrete emotional states fail to show specificity For example, some emotional typologists consider fear to have subtypes, which might involve fleeing or freezing, both of which can have distinct physiological patterns and potentially distinct neural circuitry13 As such no definitive correlation can be drawn linking specific autonomic patterns to discrete emotions, causing emotion theorists to rethink classical definitions of emotions

Psychophysiological inference and physiological computer gamesedit

Physiological computing represents a category of affective computing that incorporates real-time software adaption to the psychophysiological activity of the user The main goal of this is to build a computer that responds to user emotion, cognition and motivation The approach is to enable implicit and symmetrical human-computer communication by granting the software access to a representation of the user's psychological status

There are several possible methods to represent the psychological state of the user discussed in the affective computing page The advantages of using psychophysiological indices are that their changes are continuous, measures are covert and implicit, and only available data source when the user interacts with the computer without any explicit communication or input device These systems rely upon an assumption that the psychophysiological measure is an accurate one-to-one representation of a relevant psychological dimension such as mental effort, task engagement and frustration

Physiological computing systems all contain an element that may be termed as an adaptive controller that may be used to represent the player This adaptive controller represents the decision-making process underlying software adaptation In their simplest form, adaptive controllers are expressed in Boolean statements Adaptive controllers encompass not only the decision-making rules, but also the psychophysiological inference that is implicit in the quantification of those trigger points used to activate the rules The representation of the player using an adaptive controller can become very complex and often only one-dimensional The loop used to describe this process is known as the biocybernetic loop The biocybernetic loop describes the closed loop system that receives psychophysiological data from the player, transforms that data into a computerized response, which then shapes the future psychophysiological response from the player A positive control loop tends towards instability as player-software loop strives towards a higher standard of desirable performance The physiological computer game may wish to incorporate both positive and negative loops into the adaptive controller14
