You are working in a research lab that studies mechanisms of PTSD using a rodent model. To do this, you use the following protocol: 1. Place rats in a cage. Play a sound and measure fear response. 2. Place rats in a cage. Play a sound and apply a light, but aversive electrical shock to the rat's paw. Measure fear response. Repeat 10 times. 3. Place rat in a cage. Play a sound and measure fear response. What type of memory is involved in this task? semantic declarative classical conditioning priming

Question
### Study on PTSD Mechanisms Using a Rodent Model **Objective:** To investigate the mechanisms of Post-Traumatic Stress Disorder (PTSD) in rats through a controlled experimental protocol. **Protocol:** 1. **Initial Fear Response Measurement:** - Place rats in a cage. - Play a sound and measure the fear response of the rats. 2. **Conditioning Phase:** - Place rats in a cage. - Play a sound and apply a light. Concurrently, administer an aversive electrical shock to the rat's paw. - Measure the fear response of the rats. - Repeat the conditioning process 10 times to establish a learned association. 3. **Post-Conditioning Fear Response Measurement:** - Place rats in a cage. - Play the sound again and measure the fear response without applying the electrical shock. **Question:** What type of memory is involved in this task? Options: - Semantic - Declarative - Classical Conditioning - Priming ### Explanation: - **Classical Conditioning:** In this experiment, the rats are subjected to classical conditioning. This is a learning process that occurs through associations between an environmental stimulus (the sound) and a naturally occurring stimulus (the electrical shock). Here, the rats learn to associate the sound with the subsequent shock, leading to a conditioned fear response to the sound alone.
