08 - 28 – 08 Drive, Motivation, and Time Budgets 1. Drive theory a. Hydraulic model b. Approach-avoidance conflict c. Displacement behavior d. Redirected behavior 2. Time budgets, ethograms, and behavioral analysis Hydraulic Theory of Drive Drive Theory attempted to explain how animals make choices about activities. In the absence of early neuron interaction info A. Energy accumulates B. Energy is drained in activities; opening and closing valves determines priority of activity OR A. “Drive” energy flows into the tank B. High priority activities drain energy first, low priority activities receive energy only if energy is available What is a contemporary view of how day to day and long-term behavioral changes are modulated? Interaction between endocrine system and neurotransmitters Fight or Flight Responses Testosterone has important role in priming animal to fight, but epinephrine kicks in when an animal is actually challenged. Endocrine modulation can be considerably more complex than maturation of territorial/aggressive impulses Development or seasonal changes likely have an endocrine … Simple example is the role of epinephrine in making animal physiologically ready… The Mood Triangle This applies to humans but does it also work for animals?

This raises the largely unanswered question of personality and individual differences in broader range of animals (such as birds and non-human mammals). We’ll return to his later in the semester Approach-Avoidance Conflict (fight or flight)r Displacement, Redirection, and Animal Welfare 1. Displacement a. Taking it out on the younger sibling b. Continuous pacing 2. Redirection a. Excessive grooming b. Feather plucking c. Some sort of anxiety/behaviors that are the result of unexpended drive energy/unresolved fight/flight (drive) d. Self-directed Behaviors (SDB) as a form of displacement If we understand the effect of such behavior: Put them in challenging environments. Find them appropriate outlets.
