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






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






3. Triggered by irritation of the larynx






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






5. Prevents overexpansion of the lungs during forceful breathing






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






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






8. The major share of the response to the environment






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






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






11. Recovery of the conditioned response after extinction






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






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






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






15. Involves adaptive responses to the environment






16. 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






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






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






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






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






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






22. 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






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






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






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






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






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






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






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






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






31. Animals secrete phermones






32. 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






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






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






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






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






37. 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






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






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






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






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






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






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






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






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






46. Relatively unlikely to be modified by learning






47. Stimulus that elicits the behavior of fixed action patterns






48. Will prevail over a subordinate






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






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