    Study Notes

    Cognition Exam 3 - Study Notes

    • Anterograde amnesia: Can be caused by brain injury combined with poor nutrition (thiamine deficiency), often from alcoholism.

    • Korsakoff's Syndrome: Characterized by poor memory, difficulty remembering recent events, and potentially learning new things. Symptoms worsen when severe, lasting greater than 8 years. Patients may repeat responses or have difficulty recalling information, but may still be able to learn new material, and improve performance in some areas.

    • Medial temporal amnesia: A few minutes later, a patient may incorrectly recall Phoenix as an answer for a question of cities.

    • Alzheimer's disease: A patient, when asked to recall the word "leopard", will show little to no increase in recalling the word, even if they are asked soon after.

    • Huntington's Disease: The deterioration of the basal ganglia causes symptoms such as impaired response generation including motor actions, speech, and recall.

    • Alzheimer's disease: Associated with plaques and tangles in the cortex.

    • Infant Mobile Recognition: A 3-month-old infant responds to a mobile kick, when prompted with the same mobile after 72 hours.

    • Reaction Time (RT): Linear increase with set size when recognition of digits (1-6) is tested.

    • Recognition vs. Recall: Changed recognition criteria impacts results.

    • Grade School Classmates: College students identify former grade school classmates best using 100 photos, split into recognized and unrecognized categories.

    • Midazolam: Drugs affect recognition, especially frequencies of word recall.

    • Eyewitness Lineups: Probability of false alarms increases regardless of whether the perpetrator is present or not.

    • Word Trigrams: Better recall on the fifth trial compared to other trials if the word trigrams are from different categories.

    • Recall of Countries: Reporting names of all countries in 20 seconds leads to high recall.

    • Effective Cues: Cues like recalling secondary information (sports franchises) help recall cities better than just basic city names.

    • Recalling People: Ability to recall people from a night's event increases after 5 days.

    • Electric Shock Therapy (ECT): Can cause problems with memory and learning, leading to a mild case of anterograde amnesia.

    • William's Syndrome: Questions about height are often harder for patients with Williams syndrome to answer.

    • Cognitive Reflection Task: Reveals a tendency to accept obvious answers without full evaluation.

    • Illusion of Explanatory Depth: Claiming understanding without clear explanation of how things work (e.g. airplane flight).

    • False Memories: Memory may be influenced by post-event information (for example, remembering an event better if told about it later—in an experiment context.)

    • College Knowledge Retention: Recall of academic material is likely to remain accurate many years after college.

    • Flashbulb Memories: Relatively accurate for memorable, unique events; however, they may not be 100% accurate.

    • Fugue State: Period where a person loses their identity (and does not remember events prior to the loss of identity).

    • Amnesia / Confabulation: Damage to the temporal lobe leads to confabulation (making up memories).

    • Children's Storytelling: Children under four years old cannot construct and tell stories or tell complete memories.

    • Expert vs. Novice Chess Players: Experts spend more time carefully evaluating fewer potential moves.

    • Brain Damage/Everyday Tasks: Someone with prefrontal cortex damage will have problems with daily tasks, like organizing their materials.

    • Functional Fixedness: The inability to utilize objects in novel ways (e.g., using a knife to pick up food instead of a fork).

    • Visual Imagery/Words: Visual imagery words take longer to verify than words involving non-visual details (e.g. "hear").

    • Deductive Reasoning: Concrete versions of problems are easier for people than abstract versions.

    • Intelligence: Defined as the ability to perform cognitive tasks.

    • Cross-sectional Studies: Results suggest processing speed, working memory, and verbal learning declines after the third decade of life.

    • Intelligence Tests: Scores have increased over time across various groups.

    • Triarchic Theory of Intelligence: Features three elements: analytical, creative, and practical intelligence.

    • Familiarity and Recall: Judgment of familiarity and similarity can impact recognition of two similar or two dissimilar things.

    • Decision Making in Combat: Choosing the best course of action (e.g., combat strategy) relies on various elements.

    • Representativeness Heuristic: Judging similarities between familiar things more quickly than unfamiliar things.

    • Availability Heuristic: The potential for an event will be perceived as more likely if more or easier-to-access examples are available.

    • Academic Material: People will often recall academic material for a longer time period than some other unrelated memories, or memories from work (depending on the memory subject).
