GRE Psychology: Physiological/behavioral Neuroscience 2

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. Endogenous rhythms that revolve around a 24 hour time period






2. dominant gene always beat out recessive gene - recessive gene is not manifested unless it is paired with another recessive gene - combination of dominant and recessive genes determines what he/she looks like






3. Scouting bees look for food and nesting sites; can use landmarks as simple location cues - also sun - polarized light - and magnetic fields as aids






4. present in all normal members of a species - - stereotypic in form throughout members even for the first time - independent of learning or experience






5. Made up of external characteristics (eye color - size - etc)






6. Dance of the honeybees - and also studied senses of fish






7. Closely related to ethology - different species are compared in order to learn about their similarities and differences. Draw from animal studies to gain insight into human functioning






8. Lorez - certain aggression necessary for survival of species - instinctual rather than learned






9. Learning happens through trial - error and accidental success - animals then act based on previous successes






10. Behaviours that precede sexual acts that lead to reproduction - to attract and isolate a mate






11. Demonstrated the interaction between heredity and environment - bright rats performed better than dull only when both sets raised in normal conditions - both groups performed well in enriched environment (lots of food and activities) - both performed






12. Tinbergen - males develop red coloration on belly - which is the releasing stimulus for attacks; males attacked red-bellied crude models rather than the detailed but non-red models






13. Contrived breeding - mates intentionally paired to increase chances of producing offspring with particular traits






14. Von Frisch - once a scouting bee locates a promising food source - returns to hive and conveys the location through movements; round or waggle dance - the longer the dance the farther the food - the more vigorous display the better food; performed on






15. Chemicals detected by vomeronasal organ - acts as messengers between animals - primitive form of communication - can transmit states such as fear or sexual receptiveness






16. how one looks and sometimes acts - partially determined by heredity or genotype - but can also be influence by environment






17. Bees when sun is obscured by clouds - bees can use this navigational cue to infer sun positioning






18. Form of natural selection - not the fittest that win but those with greatest chance of being chosen as a mate (best fighters - most attractive - etc)






19. Lorenz - certain species (often birds) young attach to first moving object they see - displayed by a 'following response' - subjective to sensitive learning period - after that period this would not occur






20. Evolved form of deception - ex: harmless snakes may mimic coloration and pattern of more poisonous ones to escape predation






21. Basic unit of heredity - made of DNA molecules - organized in chromosomes - Human nucleus cells contains 23 pairs of chromosomes. Chromosomes in cells act as carriers for genes - and therefore for heredity






22. Bred 'maze bright' and 'maze full' rats to demonstrate heritability of behaviour






23. Lorenz - triggered by releasing stimuli - automatic and innate - instinctual - complex chains of behaviour; four defining characteristics: 1) uniform patterns - 2) performed by most members - 3) more complex than simple reflexes - 4) cannot be interr






24. Some use map-and-compass navigation (landmarks and sun or stars) - some have true navigational abilities and can point toward their goal with no landmarks and from any position (e.g. captured birds eventually arrive at their usual goal anyway); birds






25. Navigate at night but do not use echolocation - like humans localize sound direction and distance by binaural cues (compare intensities - arrival times) - but better at determining elevation of sound source due to asymmetrical ears






26. Worked with chimpanzees and insight in problem solving - chimps could perceive the whole situation to create new solutions rather than by trial and error; chimps had to use tools or create props to retrieve rewards






27. Harlow - the isolated monkeys --> - the lack of interaction and socialization hampered social development - - once brought together with others - males did not display normal sexual functioning and females lacked maternal behaviours






28. Sperm or ovum - haploid (23 single chromosomes)






29. E.g. rodents reared in isolation perform instinctual nest-building but much less efficient and successful than those exposed to learning opportunities






30. Reproductive isolating mechanism - different species breed in different areas to prevent confusion or genetic mixing






31. Birds - many birds can use star patterns and movements as navigational cue






32. Pigeons and bees have magnetic sensitivity - allows them to use earth`s magnetic forces as navigational cue






33. Ability to reproduce and pass on genes






34. When animal replaces a trained or forced response with a natural or instinctive response Ex: a dog with the nature to bark at visitors thinking they are intruders might have been taught to sit quietly when a guest enters through reward and punishment






35. Tinbergen - peck at end of parents' bills which have a red spot on the tip - parents then regurgitates food for chicks; chicks pecked more at a red-tipped model bill than at a plain model bill; the greater the contrast between bill and red spot even






36. Founder of ethology - imprinting - animal aggression - releasing stimuli - fixed action patterns






37. Reproductive isolating mechanism - courtship or display behavior of a particular species allows an individual to identify a mate within its own species






38. Founder of modern ethology - models in naturalistic settings - stickleback fish and herring gull chicks






39. The pair up of possible dominant and recessive gene variations for each characteristic






40. How particular genotypes selected out or eliminated from a population over time






41. Experiments that attempt to separate effects of heredity and environment - sibling mice separated at birth and placed with different parents or situations; later differences in aggression attributed to experience rather than genetics






42. The internal physiological changes that occur in an organism in response to a perceived threat (increase in HR or respiration)






43. Bees dance to indicate food is extremely nearby






44. Harlow - monkeys became better at learning tasks as they acquired different learning experiences - eventually learned after only one trial






45. Times when a developing animal is particularly vulnerable to the effect of learning (e.g. birds learning their species' song - if reared in isolation cannot develop normal song later. and imprinting)






46. Pigeons sensitive to pressure changes in altitude as navigational cue






47. Period in which a female is sexually receptive (usually used to describe non-human mammals)






48. Prevent interbreeding between two different (but closely related / genetically compatible) species - four types: 1) behavioral isolation - 2) geographic isolation - 3) mechanical isolation - 4) isolation by season






49. Only one queen bee - which produces a chemical that suppresses ovaries in all other female bees - constantly tended to and fed - lays thousands of eggs in the spring; when eggs mature - scouts finds new site for old queen and her workers - a new quee






50. Behaviours that seem out of place - illogical - and no particular survival function (e.g. scratching your head while thinking)
