Recording-piaget schema accommodation ans assimilation of new information

Schema Concept

  • Definition: A schema is a generalization of past experiences that forms a scripted pattern of thought.

  • Example: Different mental processes when thinking about going to a restaurant:

    • Some visualize standing in line, ordering, eating, and disposing of trash.

    • Others imagine being seated, sharing dishes, and leaving a generous tip.

  • Analogy: A schema can be visualized as a child's toy that provides a mental framework.

Assimilation and Accommodation

  • When new information aligns with existing knowledge (e.g., recognizing a square when already understanding a triangle), it enters the brain through assimilation.

  • If the new information is completely different (e.g., learning about a star), accommodation is required - this involves changing the existing schema.

  • Cognitive Process:

    • Assimilation: Integrating new information into existing frameworks.

    • Accommodation: Remodeling existing schemas to incorporate new understandings.

Experience and Understanding

  • Example of color blindness:

    • A person cannot truly understand the color red without experiencing it, illustrating the need for accommodation for unique experiences.

Bartlett's War of the Ghosts Experiment

  • Overview: Frederick Bartlett illustrated how schemas unconsciously impact memory and perception.

  • Method: He read a native American folktale to British students and monitored their recollection over time.

  • Findings: Three key observations emerged:

    1. Omission of Unfamiliar Detail:

      • Students often forgot details (e.g., hunting seals) that didn't fit their cultural schema, leading to difficulties in understanding and retaining this information.

      • Resulting memory is not transferred into long-term recall.

    2. Familiarization of the Strange:

      • Some students who remembered hunting seals later described it as fishing, reflecting the tendency to adapt unfamiliar experiences into familiar contexts.

      • This showcases how unique information is often channeled through familiar schemas, altering original experiences.

    3. Rationalization of the Illogical:

      • Initially, the tale seemed strange to students, yet, over time, they began to rationalize it as sensible (e.g., interpreting going to war as merely wanting to fish).

      • Indicates that memory is flexible and can continuously change upon repeated recall, showing that long-term memories are not fixed and can be adjusted.

Implications of Memory and Perception

  • Bartlett's experiment supports existentialist views that people constantly construct and adjust their past memories.

  • Much of what is remembered is rationalized into a coherent self-narrative that provides meaning to life events.

  • Jean Piaget's contribution: He argued that experiences are structured into schemata, which help individuals make sense of the world.
