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






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






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






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






5. Involves adaptive responses to the environment






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






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






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






10. Natural bodily rhythms of eating and satiation






11. The major share of the response to the environment






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






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






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






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






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






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






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






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






20. Will prevail over a subordinate






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






22. Stimulus that elicits the behavior of fixed action patterns






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






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






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






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






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






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






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






30. 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






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






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






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






34. 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






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






36. Prevents overexpansion of the lungs during forceful breathing






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






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






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






40. Recovery of the conditioned response after extinction






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






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






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






44. 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'






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






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






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






48. Rapid automatic response to a stimulus






49. Submission display -ex: happy dog wagging tail






50. Triggered by irritation of the larynx
