AIM: Describe instinctive and learned behaviors as well as patterns of behavior in animals? OBJ: Given notes and activity sheet SWBAT describe types and patterns of behavior in animals with 70% accuracy DN: Copy notes ACT: Introduction to behavior / patterns of behavior (notes) HW: Text, read p and p ; Complete What is Behavior? Activity Sheet; Vertebrate Exam, this Wednesday, Dec. 3

Lesson Notes Stimulus: a signal that causes an organism to react in some way. Response: an organism’s reaction to a stimulus. (All animal behaviors are caused by stimuli) Function of Behavior: survival and reproduction

Lesson Notes Instinct: behavior without being taught (not learned); a response that is inborn (coded in the genes) and performed correctly the first time. Learned Behavior: change in behavior based on practice or experience. Types of Learned Behavior: 1. Imprinting: newborn recognizes and follows the first moving object they see (e.g., duckling follows human)

Lesson Notes 2. Conditioning: a specific stimulus or response leads to a good or a bad outcome (e.g., Pavlov’s dog, salivate at the sound of a bell). 3. Trial-and-Error Learning: repeated practice that results in a reward and avoids behaviors that result in a punishment. 4. Insight Learning: using what you know to solve a problem.

Lesson Notes Patterns of Behavior Communication: animals use sounds, scents, body movements to communicate. Pheromone: a chemical released by one animal that affects the behavior of another animal of the same species (e.g., ant pheromone trail). Aggression: a threatening behavior that one animal uses to gain control over another animal. Aggression is due to competition over limited resources (food, water, space, shelter, and mates).

Lesson Notes Courtship Behavior: behavior to prepare for mating. Group Behavior: beneficial for safety in numbers and sharing (cooperation) in work, food, water, shelter. Circadian Rhythms: behavior cycles that occur over a day (e.g., awake/work daylight, sleep night time). Hibernation: sleep/reduced activity during winter in which the need for food has stopped. Migration: routine, seasonal journey of an animal from one place to another and back again.
