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






2. Prevents overexpansion of the lungs during forceful breathing






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






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






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






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






7. Relatively unlikely to be modified by learning






8. 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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






27. Rapid automatic response to a stimulus






28. 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






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






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






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






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






33. Will prevail over a subordinate






34. Natural bodily rhythms of eating and satiation






35. Animals secrete phermones






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






37. Recovery of the conditioned response after extinction






38. Stimulus that elicits the behavior of fixed action patterns






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






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






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






42. Involves adaptive responses to the environment






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






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






45. Submission display -ex: happy dog wagging tail






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






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






48. 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






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. Stimulated by changes in pH - PCO2 - and PO2
