Study Notes

Cognitive Psychology Exam 1

  • Cognitive Psychology: Study of mental processes like thinking, learning, and memory.

  • Greek Philosophers: Early thinkers about cognitive processes.

  • Early Theorists:

    • Wundt: Developed structuralism, analyzing basic mental processes.
    • Ebbinghaus: Studied memory, known for memory experiments.
    • James: Developed functionalism, focused on how the mind functions in real-world situations.
    • Watson/Skinner: Behaviorism, focuses on observable behavior, not internal mental states.
    • Information Processing Approach: Views the mind as a computer processing information in stages. Stages include input, processing, and output. Info is taken, processed, and outputted.
    • Cognitive Revolution: Shift in psychology toward studying mental processes, influenced by developments in linguistics and language. A reaction against behaviorism.
    • Different Methods of Cognitive Research: Various research designs including behavioral experiments, neuroimaging techniques (e.g., fMRI), neuropsychological examinations, psychological tests, and case studies. Measuring reaction times, neurological examinations, behavioral research, and neuroimaging are methods to determine how learning occurs. Neuropsychological tests and case studies are crucial.
  • Neurons: Basic units of the nervous system; includes cell body, dendrites, and axon. Sensory receptors and synapses. Function includes reacting to stimuli.

  • Sensory Receptors: Receive external stimuli and transmit information to the brain.

  • Synapse: Junction between nerve cells, allowing communication. Includes presynaptic and postsynaptic components. Structure and function are analyzed, focusing on how information is relayed.

  • Neuronal Communication: Information transmitted between neurons through action potentials and neurotransmitters. The direction of travel, and presynaptic and postsynaptic cells.

  • Action Potentials: Electrical signals that travel down neurons.

  • Neurotransmitters: Chemical messengers that carry signals across synapses.

  • Brain Structures and Cognition: Regions of the brain. Four lobes (frontal, parietal, temporal, occipital). Other areas, like the hippocampus and amygdala. Functions of these areas are studied. Brain structures are analyzed based on cognitive processing and associated functions.

  • Methods of Studying the Brain: Techniques to study brain function, including behavioral studies, neuroscience, and neuropsychological examinations. Studying the effects of brain damage, animal models, and medical evaluations. Individual case studies, like Phineas Gage, are important. Studying brain function involves studying patients who have experienced brain damage, measuring cognitive performance in patients. Neuroimaging tests like fMRI and PET scans. Various behavioral and experimental methods are used to assess cognitive function.

  • Perception: The process of organizing and interpreting sensory information

    • Bottom-up, Top-down: Two types of perceptual processing; bottom-up starts with raw data, top-down uses prior knowledge and expectations.
    • Human vs. Computer Perception: Comparison of how humans and computers perceive the world.
    • Perceptual Constancies: Mental abilities to maintain perception of objects despite changes in viewing conditions (size, shape, and color).

Attention

  • How to Measure Attention: Methods to assess attentional processes (e.g., shadowing tasks, Dichotic listening, cocktail party effect).

  • Selective Attention: Ability to focus on one stimulus and ignore others. Dichotic listening and shadowing tasks are used to study this ability.

  • Models of Attention: Different theoretical frameworks (e.g., filter, attenuation model, feature integration model), focusing on these specifically. Key models include the filter model, and attenuation model, and feature integration model. Factors affecting attention are studied including task load. Models of attention include studies on factors that affect attention.

  • Automaticity: Unconscious and effortless processing of familiar tasks.

  • Divided Attention: Ability to process multiple stimuli or tasks simultaneously. Affected by task difficulty, practice, and individual differences (including factors like task load). An example in studies like the gamers study of the effect of task load.

  • Inattentional Blindness: Failing to perceive a stimulus when attention is focused elsewhere.

  • Feature Integration Theory: Explanation of how we combine sensory features into unified perceptions.

  • ADHD, Unilateral Neglect, Simultanagnosia: Conditions related to attentional deficits.

Memory

  • Memory as a search process (Google): Context effects on memory (and how this affects our ability to retrieve and search memory). Contextual factors affect how we search, and retrieve memories.
  • Encoding Specificity: Retrieval cues present during learning enhance retrieval.
  • State-dependent learning: Memory enhanced in the same state during encoding and retrieval.
  • Consolidation (Synaptic vs. Systems): Process of strengthening memory traces over time, including different synaptic and systems-level changes. The distinctions between synaptic and systems-level consolidation.
  • Hippocampus: Brain region vital for memory storage and encoding.
  • Medial temporal lobe: Crucial for memory processes, including consolidation.
  • Amnesia (Retrograde vs. Anterograde): Conditions with memory impairments (retrograde amnesia is the inability to retrieve memories before a specific trauma or injury while anterograde amnesia is the inability to form new memories after a specific trauma or injury.)
  • Sleep: Role of sleep stages in memory processes, including consolidation and reconsolidation.
  • Reconsolidation: Reactivation and strengthening of memories when retrieved.
  • Perceptual Biases: Cognitive shortcuts influencing perception and memory (e.g., anchoring bias, hindsight bias, negativity bias, decoy effect, bias blind spot). Types of memory include Episodic, Semantic, Procedural, and Implicit memories.
  • Long-term memory vs. short-term memory: Difference in duration and capacity, distinguishing between STM and LTM capacities, noting how these are studied and measured.
  • Encoding: Transforming sensory information into a storable format; Types include elaborative and levels of processing encoding. Retrieval: Accessing information from memory, and the key role for retrieval cues.
