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. An inherited form of defective color vision in which hues with short wavelengths are confused (blue cone dysfunction); see world in green and red






2. Acquired language disorders - usually caused by damage in the left hemisphere; includes Broca'S: (left frontal lobe damage) and Wernickes'S (left temporal/parietal damage)






3. Skin senses that register the sensations of pressure - warmth and cold






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






5. Located underneath the cerebral cortex and includes the bottom portion of the forebrain - cerebellum - basal ganglia - medulla - pons - midbrain - thalamus - hypothalamus - amygdala - hippocampus






6. An anterograde amnesia in which one cannot form episodic memories BUT in experiments - patients that cannot identify previously heard melodies do show a preference for them -> explicit memory function has a different neurological basis than implicit

7. One of the primary noradrenergic nuclei whose ascending axons project to frontal cortex - thalamus - hypothalamus - limbic system






8. A 90-minute activity cycle occurs throughout the day as well as throughout sleep (in humans) waxing and waning alertness controlled by a biological clock in the caudal brainstem that also controls cycles of REM and slow-wave sleep






9. An ovary or teste






10. Involved in the effects of odors/pheromones in reproductive behavior - a nucleus that receives olfactory information from the olfactory bulb and accessory olfactory bulb






11. The synchronization of the menstrual or estrous cycles of a group of females - which occurs only in the presence of a pheromone in a male'S urine






12. The slowing and eventual cessation of estrous cycles in groups of female animals that are housed together; caused by a pheromone in the animals urine and first observed in mice






13. Result in either tolerance (and possible withdrawal symptoms) or sensitization (increase effectiveness of the drug)






14. Damage to this are causes clumsiness and loss of balance






15. A sensory organ that detects the presence of certain chemicals - especially when a liquid is actively sniffed; mediates the effects of some pheromones






16. 1. Stage I (non-REM sleep) 2. Stage II (non-REM sleep 3. Stage III (non-REM sleep - slow-wave sleep) 4. Stage IV (non-REM sleep - slow-wave sleep) 5. Rapid Eye Movement Sleep (REM sleep) ~takes about 90 minutes for one full sleep cycle






17. 1. ventral tegmentum to mesolimbic forebrain (cognition - reward systems - emotional behavior) 2. substantia nigra to caudate nucleus putamen (movement and sensory stimulation) 3. hypothalamus to pituitary gland (neuronal/hormonal control)






18. Irregular electrical activity of 13-30 Hz - state of arousal - attentive






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






20. Neurotransmitter in CNS - hormone in peripheral vascular system; deficiencies > depression - ADD; noradrenergic nuclei = locus coeruleus






21. Focuses light waves on the retina and is held in place by the suspensory ligament; aqueous humor on cornea side; vitreous humor on retina side






22. Abducens Nerve - moves eye






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






24. A drug that facilitates the effects of a particular neurotransmitter on the postsynaptic cell






25. A steroid hormone produced by the ovary that maintains the endometrial lining of the uterus during the later part of the menstrual cycle and during pregnancy; along with estradiol it promotes receptivity in female mammals with estrous cycles






26. Is a receptor blocker; binds with a receptor but does not activate it - actually prevents the natural ligand from binding with the receptor






27. The earlier onset of puberty seen in female animals that are housed with males caused by a pheromone in the male'S urine and first observed in mice






28. Symptom of narcolepsy - paralysis occurring just before a person falls alseep






29. In the CNS - is an amino acid that stabilizes neural activity






30. Emotional perception and expression (particularly fearful emotions and detection of threat)






31. A single - unfertilized cell created during conception; the combined egg + sperm






32. Caudate nucleus and putamen






33. Ventral part of midbrain - includes periaqueductal gray matter - reticular formation - red nucleus - and substantia nigra






34. Synchronized EEG activity during its deeper stages






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






36. Follow Hering'S Opponent Process of color vision - and only have two types: red-green and yellow-blue; other levels of color vision are tri-chromatic






37. Has a calcium-related role and produces the hormone parathyroid






38. Regulates body temperature






39. Refers to both the somatosensory cortex and motor cortex (they are a little different but very interrelated)






40. Strip of limbic cortex lying along the lateral walls of the groove separating the cerebral hemispheres - just above the corpus callosum






41. Functions in metabolism (carbohydrate - protein - lipid) and in the endocrine system'S salt/water balance - produces the hormones cortisol and aldosterone






42. 'little net'






43. Are found in the diencephalon






44. Trochlear Nerve - moves eye






45. A behavior that has different forms or occurs with different probabilities or under different circumstances in males than females






46. learning and memory -neurotransmitter released at the neuromuscular junction of skeletal muscle axons to excite the muscle to contract






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






48. Can occur after long term antipsychotic tx (opposite of Parkinson'S?); oversensitivity to dopamine






49. Acetylcholine - glutamate - gamma-aminobutyric acid - dopamine - serotonin - norepinephrine - endorphin






50. Glossopharyngeal Nerve - taste swallow
