INTRODUCTION

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What is a fixed action pattern?
A
Innate, highly stereotypic behavior, which when begun is continued to completion
B
evolutionary reason for behavior
C
the cause of a behavior
D
scientific study of how animals behave
Explanation: 

Detailed explanation-1: -Fixed action patterns consist of a series of actions triggered by a key stimulus. The pattern will go to completion even if the stimulus is removed. Scientists can test if a behavior is innate by providing a stimulus to naive-untrained-animals and to see if the behavior is automatically triggered.

Detailed explanation-2: -A Fixed Action Pattern, often abbreviated as FAP and known alternatively as Instinctive Movement or Instinct Bewegung, is a predictable series and stereotypical sequences of complex actions triggered by a cue.

Detailed explanation-3: -Fixed action patterns are said to be produced by the innate releasing mechanism, a “hard-wired” neural network, in response to a sign/key stimulus or releaser. Once released, a fixed action pattern runs to completion.

Detailed explanation-4: -Fixed action patterns are triggered by a specific sign stimulus, which is generally a specific set of sensory ques such as a particular color, shape, sound or smell. The sign stimulus triggers an innate releasing mechanism, which is a hardwired neural pathway that controls the cascade of behaviors.

Detailed explanation-5: -First, we will look at the most simple forms of innate behavior: reflex, taxis and kinesis.
