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






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






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






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






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






6. The major share of the response to the environment






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






8. 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






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






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






11. 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'






12. Relatively unlikely to be modified by learning






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






14. Will prevail over a subordinate






15. 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






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






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






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






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






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






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






22. Natural bodily rhythms of eating and satiation






23. Rapid automatic response to a stimulus






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






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






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






27. Animals secrete phermones






28. Recovery of the conditioned response after extinction






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






30. Involves adaptive responses to the environment






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






32. Stimulus that elicits the behavior of fixed action patterns






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






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






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






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






37. Submission display -ex: happy dog wagging tail






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






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






40. Prevents overexpansion of the lungs during forceful breathing






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






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






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






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






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






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






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






48. Triggered by irritation of the larynx






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






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