Memory AP Psych

Attention and Encoding

  • The act of encoding is intrinsically linked to attention.

    • Encoding cannot occur without focused attention on the information.

    • Attention can be both conscious and unconscious, influenced by sensory registers.

    • Example: Staring into space while still registering information with the brain.

Levels of Processing

  • Shallow Processing:

    • Simply writing down a word without deeper engagement.

  • Phonemic Processing:

    • Involves recognizing how a word sounds and creating rhymes.

  • Semantic Processing:

    • Engages with the deeper meaning of the word, thereby forming stronger neural connections.

    • Example of creating a personal story to remember words better, like associating a friend’s characteristics with the information to be learned.

  • Dual Coding:

    • Combination of visual and acoustic encoding enhances memory retention.

Elaboration and Elaborative Rehearsal

  • Elaboration:

    • Making additional connections to reinforce learning.

  • Elaborative Rehearsal:

    • Repeatedly reviewing connections to strengthen encoding for better retrieval.

  • Example: Creating personal narratives tied to learning material to facilitate easier recall later.

Types of Memory

Sensory Memory

  • Extremely short duration, lasting only for a fleeting moment.

Short Term Memory

  • Lasts about 30 seconds with limited capacity.

  • Facilitated by techniques such as chunking and rehearsal.

Working Memory

  • A subset of short-term memory involved in problem-solving and reasoning tasks.

Memory Properties

  • Short-term memory has a span of about 7±2 items, making it easy to forget if not actively maintained.

  • Consolidation into Long Term Memory (LTM) is necessary for permanent retention.

Memory Retrieval Methods

  • Recall vs. Recognition:

    • Recall requires retrieval without cues (e.g., essay questions).

    • Recognition uses cues to identify correct information (e.g., multiple choice questions).

Contextual and State-Dependent Memory

  • Context Dependent Memory:

    • Memory enhanced by being in the same context as when the information was learned.

  • State Dependent Memory:

    • Internal state (mood, physiological conditions) can affect information recall.

Types of Long Term Memory

Explicit Memory

  • Semantic Memory: Knowledge of facts (e.g., definitions).

  • Episodic Memory: Personal experiences and events (e.g., specific moments from one's life).

Implicit Memory

  • Memory of skills and tasks performed automatically (e.g., riding a bike).

  • Procedural Memory: Learning how to do things.

  • Priming: Previous exposure to stimuli influences response to subsequent stimulus.

Autobiographical Memory and Reminiscence

  • Autobiographical Memory: Better retention of personal experiences.

  • Reminiscence Effect: Tendency to remember events from adolescence and young adulthood more vividly due to their emotional significance.

Forgetting and Memory Retention

  • Forgetting occurs over time, especially soon after acquiring new information.

  • Retention tends to reach a plateau where recalling further after a month might lead to loss of specific details.
