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






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






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






4. Relatively unlikely to be modified by learning






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






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






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






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






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






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






11. Animals secrete phermones






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






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






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






15. Stimulus that elicits the behavior of fixed action patterns






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






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






18. 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






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






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






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






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






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






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






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






26. Rapid automatic response to a stimulus






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






28. Prevents overexpansion of the lungs during forceful breathing






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






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






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






32. 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






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






34. Natural bodily rhythms of eating and satiation






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






36. Recovery of the conditioned response after extinction






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






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






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






40. Triggered by irritation of the larynx






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






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






43. Will prevail over a subordinate






44. 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






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






46. The major share of the response to the environment






47. Involves adaptive responses to the environment






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






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