By studying and gaining knowledge about the mechanisms of the nervous system, physiological psychologists can uncover many truths about human behavior. [ 2 ] [ page needed ] Unlike other subdivisions within biological psychology, the main focus of psychological research is the development of theories that describe brain-behavior relationships.
Psychophysiology measures exist in multiple domains; reports, electrophysiological studies, studies in neurochemistry, neuroimaging and behavioral methods. [5] 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, [6] or measures of interoceptive ...
Emotion stimulus → Physiological Response Pattern → Affective Experience. The theory itself emphasizes how physiological arousal, with the exclusion of emotional behavior, is the determiner of emotional feelings. It also emphasizes that each emotional feeling has a distinct, unique pattern of physiological responses associated with it.
Physiological behavior accounts for actions to maintain the body. It is concerned with basic bodily functions as well as measures taken to maintain health. Economic behavior accounts for actions regarding the development, organization, and use of materials as well as other forms of work. Ecological behavior accounts for actions involving the ...
For example, when using an electrolytic probe to create a purposeful lesion in a distinct region of the rat brain, surrounding tissue can be affected: so, a change in behavior exhibited by the experimental group post-surgery is to some degree a result of damage to surrounding neural tissue, rather than by a lesion of a distinct brain region.
Many of these physiological needs must be met for the human body to remain in homeostasis. Air, for example, is a physiological need; a human being requires air more urgently than higher-level needs, such as a sense of social belonging. Physiological needs are critical to "meet the very basic essentials of life". [6]
For example, studies have found that caregivers, particularly those of dementia patients, have higher levels of depression and slightly worse physical health than non-caregivers. [14] When humans are under chronic stress, permanent changes in their physiological, emotional, and behavioral responses may occur. [15]
The brain: For example, Broca's area, a small section of the human brain, has a critical role in linguistic capability. Hormones: Chemicals used to communicate among cells of an individual organism. Testosterone, for instance, stimulates aggressive behaviour in a number of species.
