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






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






3. Submission display -ex: happy dog wagging tail






4. 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






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






6. The major share of the response to the environment






7. Stimulus that elicits the behavior of fixed action patterns






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






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






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






11. 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






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






13. Triggered by irritation of the larynx






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






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






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






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






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






19. Involves adaptive responses to the environment






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






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






22. Natural bodily rhythms of eating and satiation






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






24. Animals secrete phermones






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






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






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






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






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






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






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






32. 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






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






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






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






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






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. Triggered by irritation of the wall of the nasal cavity






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






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






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






42. Will prevail over a subordinate






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






44. Relatively unlikely to be modified by learning






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






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






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






48. 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'






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






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