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






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






3. 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






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






5. Submission display -ex: happy dog wagging tail






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






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






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






9. Triggered by irritation of the larynx






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






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






12. Natural bodily rhythms of eating and satiation






13. Relatively unlikely to be modified by learning






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






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






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






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






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






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






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






21. Prevents overexpansion of the lungs during forceful breathing






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. Substance secreted by animals that influence the behavior of other members of the same species






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






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






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






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






28. 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






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






30. Rapid automatic response to a stimulus






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






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






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






34. Animals secrete phermones






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






36. Test of conditioning is the determination of whether the condition process is actually necessary for the production of a response by a previously 'neutral stimulus'






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






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






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






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






41. Will prevail over a subordinate






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






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






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






45. Recovery of the conditioned response after extinction






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






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






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






49. Involves adaptive responses to the environment






50. Stimulus that elicits the behavior of fixed action patterns
