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






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






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






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






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






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






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






8. Rapid automatic response to a stimulus






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






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






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






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






14. Relatively unlikely to be modified by learning






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






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






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






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






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






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






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






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






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






24. Natural bodily rhythms of eating and satiation






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






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






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






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






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






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






31. Animals secrete phermones






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






33. Stimulus that elicits the behavior of fixed action patterns






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






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






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






37. 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






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






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






40. Involves adaptive responses to the environment






41. Submission display -ex: happy dog wagging tail






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






43. Triggered by irritation of the larynx






44. 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'






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






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






47. 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






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






49. Recovery of the conditioned response after extinction






50. 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
