Terms | Definitions |
|---|---|
 reticular formation | regulates sleep, wakefulness, and levels of arousal |
| cerebral cortex | outermost layer of the brain visible to naked eye & divided into two hemispheres |
| medulla | part of the brain nearest the spinal cord which controls breathing, heart rate and blood pressure |
| spinal cord | cord of nerve tissue that conducts messages between the brain and the peripheral nerves |
| hindbrain | coordinates info coming into and out the spinal cord. |
| central nervous system | The brain and spinal cord |
| sympathetic nervous system | a set of nerves that prepares the body for action in threatening situations |
| parasympathetic nervous system | a set of nerves that helps the body return to a normal resting state |
| peripheral nervous system | sensory and motor neurons that connect the central nervous system (CNS) to the rest of the body |
| limbic system | a group of forebrain structures including the hypothalamus, the amygdala, and the hippocampus, which are involved in motivation, emotion, learning, and memory |
| cerebellum | ..., a large structure of the hindbrain that controls fine motor skills |
| temporal | part of the cerebral cortex responsible for hearing and language |
| plasticity | the ability to be molded |
| occipital | region of cerebral cortex that process vision |
| monozygotic | identical twins |
| heritability | behavorial traits among individuals that can be accounted for by genetic factors |
| gene | the unit of hereditary transmission |
| electroencephalogram | Recorded information of brain activity collected through use of electric waves |
| forebrain | most highly developed part of brain; responsible for the most complex aspects of behaviour and mental life |
| dizygotic | fraternal twins (aren't identical) |
| absolute threshold | minimal intensity needed to just barely detect a stimulus |
| apparent motion | perception of movement as a resut of alternating signals |
| binding problem | how features are linked together so that we see unified objects in our visual world rather than free-floating or miscombined features |
| binocular disparity | the difference in the retinal images of the two eyes that provides information about depth |
| change blindness | ..., when people fail to detect changes to the visual details of a scene |
| feature integration | ..., the processing of different features (fast) combine features (slow), focused attention helps us bring this together |
| illusory conjunction | ..., false combination of features from two or more different objects |
| inattentional blindness | failing to see visible objects when our attention is directed elsewhere |
| just noticeable differences | ..., the smallest difference in stimulus intensity that a specific sense can detect |
| monocular depth perception | ..., Perceiving depth requiring only one eye. Though we normally use both. |
| perception | the process of organizing and interpreting sensory information, enabling us to recognize meaningful objects and events |
| perceptual constancy | ..., perceiving objects as unchanging (having consistent shapes, size, lightness, and color) even as illumination and retinal images change. |
| psychophysics | ..., the study of the correspondence between physical stimulation and psychological experience |
| sensation | a feeling or an awareness |
| sensory adaptation | ..reduced responsiveness caused by prolonged stimulation |
| signal detection | the detection that a signal is being received |
| synesthesia | ..., the perceptual experience of one sense that is evoked by another sense |
| template | ..., a mental representation that can be directly compared to a viewed shape in the retinal image |
| transduction | ..., the process whereby a transducer accepts energy in one form and gives back related energy in a different form |
| Weber's Law | ..., the just noticeable difference of a stimulus is a constant proportion despite variations in intensity |
| addiction | ..., an abnormally strong craving |
| altered | ..., changed in form or character without being completely changed |
| amphetamines | ..., drugs that stimulate neural activity, causing speeded-up body functions and associated energy and mood changes |
| apnea | ..., the absence of spontaneous respiration |
| depressants | ..., drugs that reduce neural activity and slow body functions |
| dreaming | ..., a series of mental images and emotions occurring during sleep |
| hallucinogens | ..., psychedelic drugs, such as LSD, that distort perceptions and evoke sensory images in the absence of sensory input |
| latent | ..., present, but not active; hidden |
| manifest | ..., evident; visible; obvious; V: show plainly |
| mediation | ..., the act of mediating |
| narcolepsy | ..., a sleep disorder characterized by sudden and uncontrollable episodes of deep sleep |
| narcotics | ..., specific drugs that are obtainable only by prescription and are used to relieve pain |
| psychoactive | ..., drugs and medicines that affect the brain and change how we perceive, think, or feel |
| psychoanalytic | ..., Founded by Freud. Emphasis on unconscious processes influencing behavior. |
| REM | ..., describes sleep in which vivid dreams typically occur; this type of sleep increases as the night progresses while stage 4 sleep decreases |
| self | ..., your consciousness of your own identity |
| subliminal | ..., below the level of consciousness |
| synthesis | ..., putting of two or more things together to form a whole |
| tolerance | ..., the act of tolerating something |
| unconscious | ..., not conscious |
