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. Triggered by irritation of the larynx






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






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






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






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






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






9. Involves adaptive responses to the environment






10. Prevents overexpansion of the lungs during forceful breathing






11. Rapid automatic response to a stimulus






12. The major share of the response to the environment






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






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






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






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






17. Natural bodily rhythms of eating and satiation






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






19. Recovery of the conditioned response after extinction






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






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






22. Animals secrete phermones






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






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






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






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






27. Will prevail over a subordinate






28. 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'






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






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






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






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






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






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






35. Submission display -ex: happy dog wagging tail






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






37. Relatively unlikely to be modified by learning






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






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






40. Stimulus that elicits the behavior of fixed action patterns






41. Controlled at the spinal chord -the reabsorption of water in this zone of the kidney - which permits the concentration of urine - dpeends on the permeability of the collecting tubules to water






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






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






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






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






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






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






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






49. 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






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