Emergency Financial Aid

  • Emergency financial aid programs can provide support for basic needs when unexpected situations arise.

  • Personal anecdote: The speaker discusses their experience as an undergraduate when their compel grant was revoked, emphasizing the support they received to restore it.

Required Reading

  • There is an assigned reading that spans 18 pages, prepared by Dr. G.

  • The reading aims to improve study behaviors and enhance memory, and discusses scientific insights that may challenge intuitive beliefs about learning and memory.

  • More discussion about this reading will take place in the next class.

Memory Functions

Overview

  • Memory involves three key processes: encoding, storage, and retrieval.

  • Understanding memory is crucial for grasping how neurons communicate and retain information.

Encoding

  • Encoding refers to the process of transforming sensory input into a format that can be stored in memory.

  • It includes:

    • Semantic Encoding: Associating words and meanings, not merely limited to vocabulary but also involves contextual understanding.

    • Visual Encoding: Using images and shapes to represent concepts. People tend to visualize prototypical examples of objects (e.g., a robin as a bird).

    • Acoustic Encoding: The use of sounds and rhythms, as exemplified in learning the alphabet song.

    • Connections to prior knowledge are crucial for effective encoding.

Automatic vs. Effortful Processing

  • Some memory processes are automatic (e.g., driving) while others require conscious effort (e.g., memorizing a phone number).

  • Skills develop from effortful to automatic through practice, illustrating the concept of skill building.

Effective Study Techniques

  • Self-referential connections can enhance memory retention. Connecting new information to personal experiences makes it more memorable.

  • Being conscious of how we encode information helps in effective studying strategies.

Memory Models

Atkinson-Shiffrin Model

  • Information moves through sensory memory, short-term memory, and long-term memory.

  • Sensory Memory: Very brief storage of sensory information, lasting seconds.

  • Short-Term Memory (STM): Lasts about 15-30 seconds; rehearsal can transfer information to long-term memory.

  • Long-Term Memory (LTM): Storage of information indefinitely; involves retrieval and use in daily life.

Baddeley's Working Memory Model

  • Introduces components:

    • Phonological Loop: Processes verbal and auditory information.

    • Visuospatial Sketchpad: Manipulates visual and spatial information.

    • Episodic Buffer: Integrates information across different modalities.

    • Central Executive: Oversees and coordinates information processing.

Types of Long-Term Memory

Explicit (Declarative) Memory

  • Episodic Memory: Personal experiences linked to time and place (e.g., where you were during significant events).

  • Semantic Memory: Factual knowledge (e.g., knowing names of capitals).

Implicit Memory

  • Involves skills and tasks that are performed automatically (e.g., riding a bike) without conscious thought.

  • Emotional memories may not be easily articulable but are strongly felt (e.g., fear responses).

The Role of Retrieval

  • Retrieval includes methods for recalling information from memory:

    • Recall: Generating information without prompts (e.g., essay questions).

    • Recognition: Identifying information from cues (e.g., multiple choice questions).

    • Relearning: Easier retrieval of previously learned material, highlighting "savings" effect in memory.

Cognitive Effects

  • Discussed various effects observed in memory studies such as:

    • Primacy Effect: Remembering the first items presented better.

    • Recency Effect: Remembering the most recent items better.

    • Stroop Effect: Demonstrates interference in cognitive processing when tasks conflict (e.g., naming the color versus reading the word).

Conclusion

  • There are essential strategies to enhance understanding and retention of material, and being aware of memory's nature aids in better study practices.
