Innate , Instinctive Feelings MAD. Amygdala Hijack. An instant, impulsive, irrational or uncontrolled reaction that is inappropriate in terms of extent, focus, timing etc. The reaction need not be overt. Amygdala Hijack. Reaction to threat – flood of hormones
INNATE BEHAVIOR . INNATE BEHAVIOR IN PLANTS AND PROTISTS. Innate Behavior . Any form of behavior that has not been learned is innate behavior Most innate behavior aids survival and reproduction. Innate behavior results from impulse pathways built into the nervous system.
The Modification of Instinctive Behavior. Elicited or Unconditioned Behavior. 2. Occurs without past experience Modifiable with experience (examples: habituation and sensitization. 3. Some Types of Elicited Behaviour. 4.
The Modification of Instinctive Behavior. Chapter 3. Instinctive Systems. Lorenz & Tinbergen – evolution occurs when a species incorporates environmental knowledge into its genetic structure. Greylag goose and egg-rolling. https://www.youtube.com/watch?v=7PcteKRA3zs
Innate and learned behavior. Option E.3. Assessment Statements. E.3.1 Distinguish between innate and learned behaviour . E.3.2 Design experiments to investigate innate behaviour in invertebrates, including either a taxis or a kinesis.
E3. Innate and learned behavior. E.3.1 Distinguish between innate and learned behavior. Innate behavior develops independently of the environmental context, whereas learned behavior develops as a result of experience.
OPTION E E3 INNATE AND LEARNED BEHAVIOR. E3.1 Distinguish between innate and learned behavior. Innate Behavior Learned Behavior. Instinctive – genetically based Based on experience Not modified by the individual Modified by trial and error

Innate Defenses. External defense skin, etc. pH=3-5. Mucus Membranes. Internal Defense: Phagocytosis. Phagocytic cells. Migrate OUT of the blood when the sense differences in concentration of certain chemicals engulf bacteria, dead cells, etc…. Natural Killer Cells.
Innate Immunity. 15. An Overview of the Body ' s Defenses. Resistance to most plant and animal pathogens Species resistance Due to physiological processes of humans that are incompatible with those of the pathogen Correct chemical receptors are not present on human cells
