    Study Notes

    Consciousness

    • Consciousness is the ability to monitor information from the environment and thoughts.
    • There are different levels of consciousness, ranging from full consciousness to a complete lack of consciousness.
    • Moderate consciousness occurs during sleep and dreaming.
    • Full consciousness refers to a state of alertness, but even when fully awake, fluctuations in consciousness can occur.
    • A flow state is a mental state of complete absorption and involvement in actions.
    • Mindfulness is a heightened awareness of the present moment, focusing on events in one's environment or thoughts.
    • Minimal consciousness is a state where a patient shows signs of intentional behavior but cannot communicate.

    Disorders of Consciousness

    • A coma is a state of unresponsiveness and unarousability with closed eyes.
    • The vegetative state is characterized by open eyes but unresponsive behavior.
    • Minimally conscious patients exhibit signs of intentional behavior, such as visually tracking a person.

    Attention

    • Attention is the limited capacity to process information under conscious control.

    Learning

    • Learning is a process of enduring changes in behavior with experience.
    • Association is the process of linking two pieces of information from the environment in the mind.
    • Conditioning is a type of associative learning where associations with environmental events trigger behaviors.

    Classical Conditioning

    • Classical conditioning involves learning an association between a natural stimulus (UCS) and a previously neutral stimulus (CS) that elicits an involuntary response (UCR).
    • The conditioned response (CR) is the learned behavior performed when presented with the conditioned stimulus (CS).
    • Stimulus generalization expands the association between UCS and CS to include similar stimuli.
    • Stimulus discrimination restricts the conditioned response (CR) to only the specific conditioned stimulus (CS).
    • Latent learning occurs without reinforcement and is only demonstrated later when reinforcement is introduced.

    Intermittent Reinforcement Schedules

    • Variable-ratio (VR) schedule: Reinforcement occurs after a varying number of responses (e.g., slot machines).
    • Fixed-interval (FI) schedule: Reinforcement occurs after a set amount of time (e.g., weekly paycheck).

    Social Learning Theory

    • Social learning theory involves learning through observing the behavior of others.
    • Observational learning is influenced by watching the behavior of others.
    • Modeling is the imitation of behaviors performed by others.
    • Imprinting is the rapid learning of caregiver characteristics soon after birth.

    Ethology

    • Ethology is the study of animal behavior, encompassing fields like naturalism, biology, botany, veterinary science, hunting, and farming.

    Intelligence

    • Intelligence is a set of cognitive skills that involve abstract thinking, reasoning, problem-solving and knowledge acquisition.
    • Verbal intelligence is the ability to solve problems using language-based reasoning.
    • Spatial intelligence involves the ability to accurately perceive spatial relationships and manipulate objects in space.

    Intelligence Testing

    • Intelligence tests are evaluated for reliability, validity, and cultural bias.
    • Reliability refers to the consistency of test results over time.
    • Validity measures whether a test accurately measures the intended concept (construct validity) and predicts real-world outcomes (predictive validity).
    • Cultural test bias occurs when group differences in IQ scores are influenced by cultural and educational backgrounds rather than genuine intelligence differences.
    • Test bias refers to a test's tendency to produce different outcomes for various groups.
    • Test fairness is the judgment surrounding the application of test results to different groups based on values and philosophies.

    Problem-Solving and Creativity

    • Creative problem-solving and insights involve increased activity in the frontal lobe, particularly in abstract reasoning, planning, working memory, and sensory integration.
    • The default mode network is a brain network active during periods when the individual is not focused on external stimuli and becomes less active during focused attention.
    • Creativity involves integrating ideas in original and useful ways.
    • Flexibility of thought refers to the ability to generate diverse categories of ideas and think beyond obvious solutions.
    • Originality involves coming up with unique and novel ideas.

    Learning and Memory

    • Learning is the acquisition of new knowledge or skills.
    • Memory is the ability to retain information over time.
    • Different types of memory include sensory, short-term, working, and long-term memory.
    • Sensory memory is the brief retention of sensory information.
    • Short-term memory holds a limited amount of information for a short time.
    • Working memory actively manipulates information in short-term memory.
    • Long-term memory stores information for extended periods.
    • Encoding, storage, and retrieval are the three key processes involved in memory.
    • Encoding involves converting information into a usable format for storage.
    • Storage refers to maintaining encoded information over time.
    • Retrieval involves accessing stored information when needed.

    Forgetting

    • Forgetting is the inability to retrieve information from memory.
    • Interference, decay, and retrieval failure are common reasons for forgetting.
    • Interference occurs when new or old information disrupts the retrieval of specific memories.
    • Decay refers to the gradual fading of memories over time.
    • Retrieval failure involves the temporary inability to access stored information despite its availability in memory.
