unit 2 - 2.6-2.8 notes
Retrieval: The cognitive process of accessing and bringing into consciousness information stored in memory. It includes techniques and strategies that aid in recalling previously learned data.
Recall: A specific type of retrieval wherein one must retrieve information without any external cues. For example, recalling a list of words or details from memory requires effort and often relies on the individual's ability to organize and access that knowledge without prompts.
Recognition: This retrieval method allows individuals to identify previously learned information when provided with options. For instance, recognizing a familiar name from a list is generally easier than recalling the name without assistance, as it involves a comparison to stored memories rather than full retrieval.
Retrieval cues: These are stimuli or prompts that help trigger the retrieval of a memory. They can include contextual hints, emotional states, or sensory input that were present at the time the memory was encoded, significantly facilitating the recall process.
Context-dependent memory: This phenomenon explains how memory retrieval is enhanced when the environment or situation during encoding is consistent with that of retrieval. For example, studying in the same location where one will take an exam can improve performance due to shared environmental cues.
Mood-congruent memory: The tendency to recall memories that align with one's current mood. This means that if someone is happy, they are more likely to remember other happy experiences, whereas sadness may evoke memories of past events that reflect that emotion.
State-dependent memory: A subtype of context-dependent memory where the effectiveness of retrieval is enhanced if an individual's internal state at the time of encoding (e.g., being caffeinated or relaxed) matches their state at the time of retrieval.
Testing effect: A phenomenon where actively retrieving information through testing (such as quizzes or practice exams) enhances long-term retention of that information compared to just studying the material without retrieving it, illustrating the benefits of retrieval practice on memory consolidation.
Metacognition: The awareness and understanding of one’s own thought processes. This includes the ability to monitor, control, and plan one's learning and memory strategies, allowing individuals to reflect on how they learn best and make adjustments to improve retention and understanding.
Forgetting curve: A graphical representation demonstrating how information is lost over time when there is no effort made to retain it. It showcases a rapid decline in memory retention shortly after learning, which then levels off over time, emphasizing the importance of regular review and practice for long-term memory.
Encoding failure: This occurs when information cannot be effectively remembered due to insufficient encoding during the initial learning phase, indicating that the information may not have been properly processed for long-term storage.
Proactive interference: A memory phenomenon where previously learned information interferes with the ability to learn or recall new information. This can be observed when old habits or facts hinder learning new concepts, complicating the acquisition of fresh knowledge.
Retroactive interference: In contrast, this process involves newly learned information disrupting the recall of previously learned information, often leading to confusion or memory mix-ups.
Tip-of-the-tongue phenomenon: A temporary condition where a person is unable to retrieve a word or piece of information they know is stored in memory, accompanied by a feeling of certainty that they know the answer, often described as being 'on the tip of the tongue.'
Repression (psychodynamic): A defense mechanism where the mind unconsciously blocks out painful or traumatic memories to protect the individual from emotional distress, which can lead to forgetting significant experiences and feelings.
Misinformation effect: The phenomenon where a person's memory of an event can be altered by misleading information presented after the event, resulting in inaccurate recollections, highlighting the malleability of human memory.
Source amnesia: A condition where individuals remember information but fail to recall the source of that information, which can lead to confusion regarding how or where they learned it, affecting the credibility of the memory.
Constructive memory: This refers to the process where memories are reconstructed from various cues and information, indicating that our recollections can be swayed by our beliefs, expectations, and the inclusion of new information over time.
Memory consolidation: A biological process that stabilizes a memory trace after its initial acquisition. This is crucial for transferring short-term memories into more permanent long-term storage, enabling easier retrieval in the future.
Imagination inflation: A phenomenon where imagining non-existent events can increase an individual's confidence that those events actually took place, leading to the potential creation of false memories rooted in imagination rather than reality.
Intelligence: The ability to learn from experience, solve problems, and adapt to new situations. It consists of various cognitive abilities including reasoning, problem-solving skills, and comprehension, key elements that contribute to effective functioning in daily life.
g (general intelligence): A theory posited by Charles Spearman, suggesting the existence of a single underlying factor (general intelligence) that influences performance across a diverse range of cognitive tasks, indicating a shared cognitive ability.
Intelligence quotient (IQ): A numerical score derived from standardized tests designed to measure intelligence relative to the average performance of a specific age group, with a mean score typically set at 100 to facilitate comparisons across individuals.
Mental age: A measurement of an individual's intellectual development expressed in terms of the average age at which people achieve a specific level of cognitive ability, allowing for a contextual understanding of cognitive progress.
Chronological age: The actual age of a person, generally measured in years, which is used for comparison against mental age in assessing cognitive development and performance.
Standardization: A process of establishing norms for a test by administering it to a large, representative sample, ensuring that subsequent results can be interpreted meaningfully relative to the broader population.
Validity: An essential quality of a test that refers to the degree to which a test measures what it claims to measure, assessing whether the results are meaningful and relevant to the construct being evaluated.
Construct validity: The extent to which a test truly measures the theoretical construct it is intended to assess, showing that the test results correlate with other measures of the same construct.
Predictive validity: The capacity of a test to accurately predict future performance or outcomes, such as an IQ test's ability to forecast academic success, demonstrating the test's utility beyond merely assessing current competence.
Reliability: The consistency and stability of test scores over time or across varying conditions; a reliable test yields similar outcomes under matching circumstances, which is crucial for establishing credibility.
Test-retest reliability: This measures reliability by administering the same test to the same group on two different occasions, revealing the consistency of scores across time.
Split-half reliability: A method that divides a test into two equal halves and compares the scores from each half; a high correlation indicates good reliability and consistency in measurement.
Stereotype threat: A psychological phenomenon where individuals fear confirming negative stereotypes about their social group, which can adversely impact their performance on assessments or tasks, often leading to diminished achievement.
Stereotype lift: Conversely, this phenomenon occurs when individuals perform better on tasks when reminded of a positive stereotype associated with their social group, enhancing their performance and boosting self-confidence.
Flynn Effect: A documented rise in average IQ scores over time across generations, suggesting that environmental factors such as improved education, nutrition, and social complexity significantly contribute to increases in intelligence levels over time.
Achievement tests: Standardized assessments designed to evaluate knowledge and skills in specific subjects, reflecting what an individual has learned over a particular timeframe, such as in math, reading, or science.
Aptitude tests: These tests aim to measure an individual’s potential to succeed in a particular task or field, assessing innate abilities rather than accumulated knowledge, and predicting future performance.
Fixed mindset: A belief system where individuals perceive intelligence and abilities as static and unchangeable, leading them to avoid challenges and give up easily when faced with difficulties.
Growth mindset: In contrast, this belief system suggests that intelligence and abilities can be developed through effort, learning, and perseverance, encouraging
