PCAT Biology Animal Behavior

Subject : pcat
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. Specific behaviors found in all animals which involve the evolution of a variety of complex actions that function as signals in preparation for mating






2. Includes providing food - light - or electrical stimulation of the brain's 'pleasure centers.'






3. Will prevail over a subordinate






4. Include the elements of the environment that occur in familiar cyclic patterns






5. Stimulated by changes in pH - PCO2 - and PO2






6. Stimulus that elicits the behavior of fixed action patterns






7. Rapid automatic response to a stimulus






8. Submission display -ex: happy dog wagging tail






9. Patterns of behavior that are established and maintained mainly by periodic situations -ex: response to a traffic light






10. The major share of the response to the environment






11. Involves the suppression of the normal startle responses to stimuli -repeated stimulation will results in decreased resonsiveness to that stimulus






12. Inhibits the expiratory center and stimulates the inspirator center when the lungs are in danger of collapsing






13. Unconditioned stimulus is removed or was never sufficiently paired with the conditioned stimulus






14. The gradual elimination of conditioned responses in the absence of reinforcement






15. Affect systemic blood pressure and stimulate the respiratory rate when blood pressure declines






16. Triggered by irritation of the wall of the nasal cavity






17. Specific time periods during an animal's early development when it is physiologically able to develop specific behavioral patterns






18. Involves the ability of th learning organism to respond differentially to slightly different stimuli






19. Prevents overexpansion of the lungs during forceful breathing






20. System of interactions of many neurons involving the startle response






21. Involves conditioning responses to stimuli with the Use of reward or reinforcement






22. Instinctual or innate behaviors that are predominant determinants of behavior patterns - and learning plays a relatively minor role in the modification of these predetermined behaviors






23. Natural bodily rhythms of eating and satiation






24. Ex: coughing and sneezing -operate on the exposure to chemical irritants - toxic vapors - or mechanical stimulation of the respiratory system






25. Distributing members of the species so that environmental resources are not depleted in a small region - intraspecifc competition is reduced






26. Complex reflex - learned motor pattern -ex: step on brakes when animal runs in front






27. Involves neural integration at a higher level -ex: brainstem or even cerebrum






28. Members of most land-dwelling species defend a limited area or territory from intrusion by other members of the species






29. Composed of two different reflexes: the inflation and deflation reflexes






30. Social hierarchy -minimizes violent intraspecific aggressions by defining stable relationships among members of the group






31. Involves adaptive responses to the environment






32. Relatively unlikely to be modified by learning






33. Alerts an animal to a significant stimulus -involves the interaction of reticular activating system






34. Consisting of threat displays and combat that settles disputes between individuals in population ex: dog growling






35. The ability of a conditioned organism to respond to stimuli that are similar but not identical - to the original conditioned stimulus






36. Daily cycles that when isolated from the natural phases of light and dark - they'll continue with approximate day-to-day phasing -have both internal/external






37. Process in which environmental patterns or objects presented to a devleoping organism during a brief critical period in early life become accepted permanently as an element of their behavioral environment and included in an animal's behavioral respon






38. Produce long-term behavioral and physiological alterations in recipient animals ex: male mice may affect the estrous cycles of females






39. Innate behavior that has evolved as a signal for communication between members of the same species






40. Animals secrete phermones






41. If the stimulus is no longer regularly applied - the response tends to recover over time






42. Triggered by irritation of the larynx






43. Occur as a means of communication between members of a species






44. The capacity of the nervous system - particularly the cebral cortex - for flexibility -correlated with the capacity for learning adaptive responses






45. Involves the association of a normally autonomic or visceral response with an environmental stimulus -aka Conditioned Reflex






46. Response is diminished and finally eliminated in the absence of reinforcement






47. Involves conditioning an organism so that it will stop exhibiting a given behavior pattern






48. Recovery of the conditioned response after extinction






49. Trigger a reversible behavioral change in the recipient ex: sex attractant - alarm - toxic defensive






50. Established after the organism has been conditioned - whereby stimuli further and further away from the original conditioned stimulus elicit responses with decreasing magnitued
