What is the primary difference between sensation and perception?
What is the primary difference between sensation and perception?
Sensation involves the detection of physical stimuli, while perception is how the brain organizes and interprets these stimuli to create meaningful experiences.
Describe the process of transduction in sensory systems.
Describe the process of transduction in sensory systems.
Transduction is the conversion of physical energy, such as light or sound waves, into neural signals that the brain can interpret.

Study Notes
Sensation vs. Perception
- Sensation is the detection of physical stimuli (like light or sound) by sensory organs.
- Perception is the brain's organization and interpretation of sensory input, creating meaningful experiences.
The Sensory Processes
- Detection: Sensory organs interacting with stimuli in the environment.
- Transduction: Converting physical energy (light, sound, etc.) to neural signals.
- Transmission: Sensory neurons sending neural signals to the brain for processing.
Sensory Systems
- Vision: Eyes detect light, color, and movement.
- Hearing (Auditory): Ears detect sound waves.
- Touch (Tactile): Skin receptors detect pressure, temperature, and pain.
- Taste (Gustatory): Taste buds on the tongue detect different tastes (sweet, salty, sour, bitter, umami).
- Smell (Olfactory): Nose detects odors through olfactory receptors.
- Proprioception: Sensing body position and balance through receptors in muscles and joints.
Sensory Receptors and Neurons
- Specialized cells detect specific stimuli and convert them into neural signals.
Sensory Adaptation
- Receptors become less sensitive to constant stimuli.
Reflexes and Instincts
- Reflexes are automatic responses to stimuli (e.g., blinking).
- Instincts are complex inborn behaviors for survival (e.g., bird migration).
Learned Behaviors
- Learned behaviors are acquired through experience, practice, or observation.
Associative vs. Non-Associative Learning
- Associative Learning: Forming connections between stimuli or behaviors and consequences.
- Non-Associative Learning: Changes in response to a single stimulus (habituation, sensitization).
Classical Conditioning
- Pavlov's Dogs: Associating a neutral stimulus (bell) with food to elicit a conditioned response (salivation).
Operant Conditioning
- Shaping behavior through consequences (reinforcement, punishment).
Observational Learning
- Learning by observing others.
Emotions
- Emotions are complex reactions involving physiological responses, behaviors, and subjective experiences.
- Emotions are temporary and intense; moods are long-lasting and less intense.
- Primary emotions include happiness, sadness, fear, anger, surprise, and disgust.
Brain Regions and Emotions
- Amygdala: Essential for processing emotions, especially fear.
- Thalamus: Relays sensory information to the correct brain regions.
- Hippocampus: Links emotions to memories.
Memory Stages
- Encoding: Converting sensory input into memory.
- Storage: Maintaining memory over time.
- Retrieval: Accessing and using stored information.
Types of Memory
- Sensory Memory: Brief sensory information storage.
- Working Memory: Holds and manipulates information actively.
- Long-Term Memory: Stores information for extended periods.
Declarative vs. Non-Declarative Memory
- Declarative Memory: Explicit memories (facts and experiences).
- Non-Declarative Memory: Implicit memories (skills and conditioned responses).
Personality
- Personality is enduring patterns of thoughts, feelings, and behaviors.
- Big Five Traits: Openness, conscientiousness, extraversion, agreeableness, neuroticism.
Freud's Psychodynamic Theory
- Id, ego, and superego representing different aspects of the psyche.
- Defense mechanisms protect the ego from anxiety.
Humanistic Perspective
- Maslow's Hierarchy of Needs.
- Rogers' emphasis on self-concept and unconditional positive regard.
Psychological Disorders
- DSM-5 provides criteria for diagnosing mental health disorders.
- Anxiety disorders are conditions like GAD, panic attacks, phobias, and OCD.
Psychotherapy
- Various types of therapy exist to address psychological distress.
- examples include family therapy, humanistic therapy, cognitive-behavioral therapy (CBT), and psychodynamic therapy.
Stress and Coping
- Stress is the body's response to challenges.
- General Adaptation Syndrome - body's three stages of response to stress (alarm, resistance, and exhaustion).
- Coping Mechanisms - problem-focused coping and emotion-focused coping.
- Building resilience helps cope with stressors.
