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






2. Rapid automatic response to a stimulus






3. Natural bodily rhythms of eating and satiation






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






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






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






7. Prevents overexpansion of the lungs during forceful breathing






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






9. Animals secrete phermones






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






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






12. 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'






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






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






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






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






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






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






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






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






21. Stimulus that elicits the behavior of fixed action patterns






22. The major share of the response to the environment






23. Involves adaptive responses to the environment






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






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






26. Process in which environmental patterns or objects presented to a devleoping organism during a brief critical period in early life become accepted permanently as an element of their behavioral environment and included in an animal's behavioral respon






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






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






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






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






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






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






33. Relatively unlikely to be modified by learning






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






35. Will prevail over a subordinate






36. Submission display -ex: happy dog wagging tail






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






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






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






40. Recovery of the conditioned response after extinction






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






42. 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






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






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






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






46. 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






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






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






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






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