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






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






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






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






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






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






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






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






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






10. Rapid automatic response to a stimulus






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






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






13. Triggered by irritation of the larynx






14. Will prevail over a subordinate






15. Stimulus that elicits the behavior of fixed action patterns






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






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






18. Submission display -ex: happy dog wagging tail






19. 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






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






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






22. Involves stimulating the brain's pleasure centers with links the lack of pleasure






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






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






25. Involves adaptive responses to the environment






26. Recovery of the conditioned response after extinction






27. Animals secrete phermones






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






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






30. Relatively unlikely to be modified by learning






31. The major share of the response to the environment






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






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






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






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






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






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






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






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






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






41. Prevents overexpansion of the lungs during forceful breathing






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






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






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






45. 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






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






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






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






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






50. 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'
