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






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






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






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






5. 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






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






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






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






9. Natural bodily rhythms of eating and satiation






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






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






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






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






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






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






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






17. Animals secrete phermones






18. 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'






19. Submission display -ex: happy dog wagging tail






20. Recovery of the conditioned response after extinction






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






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






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






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






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






26. Will prevail over a subordinate






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






28. Stimulus that elicits the behavior of fixed action patterns






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






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






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






32. The major share of the response to the environment






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






34. Rapid automatic response to a stimulus






35. Relatively unlikely to be modified by learning






36. Prevents overexpansion of the lungs during forceful breathing






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






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






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






40. 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






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






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






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






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






45. 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






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 larynx






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






50. Involves adaptive responses to the environment
