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






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






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






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






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






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






7. 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'






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






9. Involves adaptive responses to the environment






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






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






12. Prevents overexpansion of the lungs during forceful breathing






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






14. Complex - coordinated - and innate behavior responses to specific patterns of stimulation in the environment -innate






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






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






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






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






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






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






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






22. Recovery of the conditioned response after extinction






23. 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






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






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






26. 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






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






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






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






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






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






32. The major share of the response to the environment






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






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






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






36. Will prevail over a subordinate






37. Relatively unlikely to be modified by learning






38. Stimulus that elicits the behavior of fixed action patterns






39. 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






40. Rapid automatic response to a stimulus






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






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






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






44. Natural bodily rhythms of eating and satiation






45. Animals secrete phermones






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






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






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






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






50. Triggered by irritation of the larynx
