In operant conditioning, the strengthening of a reinforced response. 7. action potential A neural impulse a brief electrical ch arge that travels down an axon. The action potential is generated by the movement of positively charged atoms in and out of transmit in the axons membrane. 8. activation synthesis hypothesis Theory to describe dreaming that explains dreaming as being random neural activity hat the brain tries to make sense of. 9. acuity The Sharpness of vision. 10. addictionsdependency to drugs comes about from potentially one use of the substance were the body can build up dependence to the substance. 11. adolescence The transition period from childhood to adulthood, extending from puberty to independence. 12. adrenal glands A pair of endocrine glands just above the kidneys. The adrenals secrete the hormones epinephrine (adrenaline) and norepinephrine (nonadrenaline), which help to arouse the body in times of stress. 13. ll or nothing law Increasing the stimulus above the threshold will not increase the action potential intensity. The neurons action is an all or nothing response it either will fi re or it will not. The strength of the stimulus does not effect action potentials speed. 14. alpha waves The relatively slow brain waves of a relaxed, awake state. 15. alzheimers disease A progressive and irreversible brain disorder characterized by gradual deterioration of memory, reasoning, language, and, finally physical functioning. 16. blackout The loss of memory 17. mygdala Two almond-shaped neural clusters that are components of the limbic system and are linked to emotion. 18. assimilation Interpreting ones new experience in terms of ones existing schemas. 19. association areas Areas of the cerebral cortex that are not involved in primary motor or sensory functions rather, they are involved in higher mental functions such as learning, remembering, thinking, and speaking. 20. associative learning Learning that certain events occur together. The events may be two stimuli (as in classical conditioning) or a response and its consequences (as in operant conditioning). 1. attachme nt An emotional tie with another person shown in young children by their seeking closeness to the caregiver and showing distress on separation. 22. audition The sense of hearing 23. automatic nervous system The part of the peripheral nervous system that controls the glands and the muscles of the internal organs (such as the heart). Its sympathetic division arouses its parasympathetic division calms. 24. automatic processing Unconscious encoding of incidental information, such as space, time, and frequency, and of well-learned information, such as word meanings. 25. xon The extension of a neuron, ending in branching terminal fibers, through which messages pass to other neurons or to muscles or glands. 26. barbiturates Drugs that depress the activity of the central nervous system, reducing anxiety but impairing memory and judgement. 27. basiler membranewithin the cochlea of the inner ear is a soused structural element that separates two liquid-filled tubes that run along the coil of the cochlea, the scala media and the scala tympani. 28. behavioral genetics The study of the relative power and limits of genetic and environmental influences on behavior. 29.Behavioral Psychologya branch of psychology that focuses on how we learn from observable responses. An individuals response to different environment stimuli shapes our behaviors. 30. BehaviorismThe view that psychology should be an objective science that studies behavior without reference to mental processes. Most research psychologists today agree that psychology should be an objective science but do not think that it should be without reference to mental processes. 31. behaviouristic psychology The view that psychology (1) should be an objective science that (2) studies behavior without reference to mental processes.For example, intelligence may be operationally defined as what an intelligence test measures. 193. opiates Opium and its derivatives, such as morphine and heroin they depress neural activity, tem porarily lessening pain and anxiety. 194. opponent-process theory The theory that opposing retinal processes (red-green, yellow-blue, white-black) enable color vision. For example, some cells are stimulated by green and inhibited by red others are stimulated by red and inhibited by green 195. optic nerve The nerve that carries neural impulses from the eye to the brain. 96. parallel processing The processing of several aspects of a problem simultaneously the brains natural mode of information processing for many functions, including vision. Contrasts with the step-by-step (serial) processing of most computers and of conscious problem solving. 197. parallel processing The processing of several aspects of a problem simultaneously the brains natural mode of information processing for many functions, including vision. Contrasts with the step-by-step (serial) processing of most computers and of conscience problem solving. 198.Parasympathetic nervous system The division of the autonomic ne rvous system that calms the body, conserving its energy. 199. parietal lobes The portion of the cerebral cortex lying at the top of the head and toward the rear includes the sensory cortex. 200.
