#AP Psychology Study Guide: The Brain, Consciousness, and Drugs

Hey there! Let's get you prepped for the AP Psych exam. This guide is designed to be your go-to resource, especially the night before the test. We'll break down the key concepts, make connections, and get you feeling confident. Let's dive in!

#The Adaptable Brain: Neuroplasticity and Neurogenesis

#

Key Concept

Neuroplasticity

Definition: The brain's ability to reorganize itself by forming new neural connections throughout life. Think of it like your brain is a flexible, ever-changing map. 🗺️
Why it matters:
- Helps the brain recover from damage (like strokes). 💪
- Allows for adaptation to new experiences and learning. 🧠
- Explains why blind people have enhanced hearing and deaf people have enhanced visual perception.
Analogy: Imagine a city where roads can be rerouted to handle traffic after an accident. That's neuroplasticity!

#Neurogenesis

Definition: The growth and formation of new neurons. It's like the brain is constantly building new pathways. 💖
Why it matters:
- Can help heal the brain.
- Contributes to learning and memory.
Key Difference: Neuroplasticity is about rewiring existing connections, while neurogenesis is about creating new neurons.

Memory Aid

Think of it this way: Plasticity is like remodeling a house, while neurogenesis is like building a new room.

#Consciousness: Awareness and Its Levels

#What is Consciousness?

Definition: Your awareness of yourself and your environment. It's like the spotlight of your attention. 🔦
States of Consciousness:
- Spontaneous: Daydreaming, drowsiness, dreaming. 💭
- Physiological: Hallucinations, orgasm, food/oxygen deprivation. 🍔🍕
- Psychological: Sensory deprivation, hypnosis, meditation. 🧘

#Influences on Consciousness

Mere-Exposure Effect: We tend to prefer familiar stimuli over new ones. It's like that song you didn't like at first but now love. 🎶
Priming: Exposure to one stimulus influences our response to a later stimulus. It's like a mental shortcut. ⚡
Blindsight: Blind people can still describe the path of an object they can't see, showing that some processing happens outside of visual awareness. 🤯

#Levels of Awareness (Freud's Model)

Conscious: Everything you are currently aware of (what you see, hear, touch, taste, and smell). 👀👂✋👅👃
Preconscious: Information not currently in your awareness but easily retrievable (like what you had for breakfast). 🥓🍳
Unconscious: A reservoir of unacceptable thoughts and feelings (often sexual) that are processed without awareness. 🤫

#Other Levels of Consciousness

Subconscious: Information we are not consciously aware of, but influences our behavior. 🤓
Nonconscious: Body processes we don't control (heartbeat, respiration, digestion). ❤️

Memory Aid

Remember the levels with this: CUP-SN (Conscious, Unconscious, Preconscious, Subconscious, Nonconscious).

      "1 point for correctly defining the preconscious level as information that is not currently in awareness but can be easily retrieved.",

      "1 point for explaining how each level influences our thoughts and behaviors (e.g., conscious awareness guides actions, preconscious memories influence decisions, unconscious desires affect behavior)."

#Cognitive Neuroscience and Dual Processing

#Cognitive Neuroscience

Definition: The study of the biological processes that underlie our ability to think, especially through neural connections. 🧠
Focus: Understanding how the brain enables us to learn, remember, and make decisions.

#Dual Processing

Concept: We process information on two tracks: conscious and unconscious.
Why it matters:
- We can only pay attention to a few things at a time, but we still process a lot of information unconsciously. 🤯
- This allows us to react quickly and efficiently to our environment.
Analogy: Think of it like driving a car. You're consciously aware of the road, but your unconscious mind is handling many of the small details. 🚗

Study Guide Overview

This AP Psychology study guide covers neuroplasticity and neurogenesis, including their definitions and impact on behavior. It also explores consciousness, covering its states, influences (like the mere-exposure effect and priming), and levels of awareness (from Freud's model to other concepts like subconscious and nonconscious processing). Additionally, it examines cognitive neuroscience and dual processing, highlighting how we process information on two tracks. Finally, it touches on drug addiction and dependence.
