Exam 3 Study || Ritualization vs. Receiver-Bias Mechanisms

Based on part 16.

Ritualization

Where the incipient signals become more stereotyped and unambiguous in a population over evolutionary time.

Ritualization Focus

Focuses on the characteristics of the sender of the signal.

Who favors Ritualization?

Ethologists

Intention Movements

A behavior derived from locomotory movements. Part of Ritualization.

Displacement Activities

Occurs when an animal experiences high motivation for two or more conflicting behaviors. Part of Ritualization.

Autonomic Responses

The involuntary nervous system and regulates many of the body’s visceral activities. Part of Ritualization.

Emancipation

When a ritualized signal has become freed from the external or internal factors that originally led to it.

Reciever-Bias Mechanisms Focus

Focuses on the characteristics of the recipient and how that may influence the evolution of a signal.

Who favors Receiver-Bias Mechanisms?

Comparative Psycologists

Sensory Exploitation

When a receiver has a preexisting bias for a particular stimulus and the sender’s signal will evolve to exploit this bias. Part of Receiver-Bias Mechanisms.

Sensory Drive

The receiver’s characteristics are shaped by the environment and that will affect the signal evolution. Part of Receiver-Bias Mechanisms.
