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. Rapid automatic response to a stimulus






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






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






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






5. Stimulus that elicits the behavior of fixed action patterns






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






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






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






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






10. Natural bodily rhythms of eating and satiation






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






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






13. Will prevail over a subordinate






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






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






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






17. Relatively unlikely to be modified by learning






18. Animals secrete phermones






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






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






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






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






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






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






25. Triggered by irritation of the larynx






26. 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






27. Prevents overexpansion of the lungs during forceful breathing






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






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






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






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






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






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






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






35. Involves adaptive responses to the environment






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






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






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






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






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






41. 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






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






43. Recovery of the conditioned response after extinction






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






45. Submission display -ex: happy dog wagging tail






46. The major share of the response to the environment






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






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






49. 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'






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