Gre Psychology: Experimental/natural Science Biology

Subjects : gre, psychology
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Phantom limb pain - hypnotic induction and the success rate of placebo treatments






2. Opening in the iris; dilates and contracts allowing different levels of light in






3. Associated with (spoken) language reception/comprehension - memory processing - and emotional control; contains Wernicke'S area and the auditory cortex






4. If head is rotated - eye movements occur in the same direction






5. Instead of one continuum for sex (masculine-feminine) - her work in the presence of both masculine and feminine features/development suggests these are actually two separate continuums (defeminized-feminized and unmasculinized-masculinized)


6. Causes mesolimbic dopamine hyperactivity; etiology of schizophrenia






7. Facial Nerve - moves face and salivates






8. Pleasure center of the brain; discovered by Olds & Milner






9. Part of limbic system; protrusion of the bottom of the brain at the posterior end of the hypothalamus - contains some hypothalamic nuclei






10. Supernormal






11. A patient who had intact intelligence but an inability to learn/remember anything new (severe anterograde amnesia)






12. Occurs when a neuron is hyperpolarized and characterized by sufficient strength of stimulation triggering a new action potential






13. Termination of pregnancy by the odor of a pheromone in the urine of a male other than the one that impregnated the female; first observed in mice






14. Extensive research in dreams - said BAH to Freud; proposed the activation-synthesis hypothesis (dreams are nothing more than the product of random electrical impulses)






15. The maintenance of water balance in the body






16. Caudate nucleus and putamen






17. Occurs for body temperature - blood glucose levels - blood concentration - etc -hormones are important






18. Bunch of dopaminergic neurons starting in the ventral tegmental area and ending in the nucleus accumbens - amygdala and hippocampus






19. Found in the ventricles and spinal canal






20. Contains receptors to detect when the body needs food or fluids; the hunger center; lesions lead to aphagia






21. A large network of neural tissue located in the central region of the brain stem - from the medulla to the diencephalon






22. Occurs intermittently during early stages of slow-wave sleep and REM sleep 3.5-7.5 Hz






23. Is an oversensitivity to dopamine (D2)






24. Are postsynaptic potentials that are found in the dendrites and vary in their intensity






25. A chemical released by one animal that affects the behavior or physiology of another animal; usually smelled or tasted






26. Relays nerve impulses - processes sensory impulses - reflex behavior and contains nerve cell bodies






27. Short bursts of waves 12-14 Hz that occur 2-5 times a minute during stages 1-4 of sleep; most characteristic of sleep Stage II; some believe sleep spindles are involved in keeping one asleep (decline in older people)






28. Sudden - sharp waveforms found only in Stage II of sleep; spontaneously occur about one per minute but also to unexpected noises






29. Oculomotor Nerve - moves eye pupil






30. Eating - sex - aggression - sleep - focus on subcortical and neuroendocrine control of behavior






31. States that performance is worst at extremely low or extremely high levels of arousal and optimally at an intermediate level






32. Tremors - rigidity of limbs - poor balance and difficulty initiating movements


33. These two developed the criteria for habituation; basic process is a form of synaptic depression that occurs presyntaptically.






34. Dorsal part of midbrain; includes the superior and inferior colliculi






35. Sign






36. Has neurons for reflexes






37. Bunch of dopaminergic neurons starting in the ventral tegmental area and ending in prefrontal cortex






38. Holds the lens in place






39. Two different presynaptic neurons/inputs to a post-synaptic cell






40. An axon of a neuron in one region of the brain whose terminals form synapses with neurons in another region






41. Increasing effects/effectiveness of a medication due to repeated administration






42. Affect multiple receptors; highly preferential to which type of receptor they affect






43. Lens changes initiated by the ciliary muscles to change the shape of the lens in order to focus image on the retina






44. Reduces anxiety - released with NE in amygdala - hippocampus - basal ganglia - periaqueductal gray region - locus coeruleus and PFS; NPY is diminished in persons with PTSD/CPTSD and those exposed to chronic stress






45. Binding of a drug to a receptor site that does not interfere with the binding site for the principal ligand






46. Hypothalamic-pituitary-adrenal axis -controls stress response






47. Research indicates that the expressing of negative emotions is associated with increased immune function; inhibiting negative emotions with decreasing immune function






48. Means 'Savory' in Japanese and is a taste receptor found on the tongue; activated by glutamate present in meats - cheese and other protein heavy foods






49. When a neuron reaches its excitation threshold - the neuron will produce an action potential of FIXED amplitude regardless of the magnitude of the stimulation






50. Moving forward
