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. Stimulated by changes in pH - PCO2 - and PO2






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






3. Natural bodily rhythms of eating and satiation






4. Animals secrete phermones






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






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






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






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






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






10. Will prevail over a subordinate






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






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






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






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






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






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






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






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






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






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






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






22. 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'






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






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






25. Triggered by irritation of the larynx






26. Prevents overexpansion of the lungs during forceful breathing






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






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






29. Recovery of the conditioned response after extinction






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






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






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






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






34. Involves adaptive responses to the environment






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






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






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






38. 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






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






40. Stimulus that elicits the behavior of fixed action patterns






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






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






43. Submission display -ex: happy dog wagging tail






44. Rapid automatic response to a stimulus






45. Relatively unlikely to be modified by learning






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






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






48. 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






49. 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






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