Study Notes

Gestalt Theory

Founded by Max Wertheimer, an Austrian psychologist, focusing on how we organize information.
Gestalt translates to "whole form," emphasizing perception as holistic rather than fragmented.
Involves two processes: bottom-up (BU) and top-down (TD), which can operate in tandem or manifest dominantly as TD.

Key Principles of Gestalt

Proximity: Items that are closer together are perceived as related or grouped.
Similarity: Similar objects (in shape, color, etc.) are naturally grouped by the brain.
Good continuation: Preference for continuous lines and shapes over abrupt endings.
Common region: Elements within a defined area are perceived together.
Connectedness: Connected items are seen as a single unit.
Contour: Perception continues across lines or boundaries.

Cognitive Processes and Conflicts

Individuals prioritize proximity over similarity, often focusing on color over shape when interpreting visual information.

Object Memory

Iconic Memory: Temporary storage of visual stimuli lasting between 120ms to 240ms; related to sensory memory.
Visual Persistence Principles:
- Neural: Continuation of activity in response to a stimulus that is no longer present.
- Visible: Briefly perceived stimuli can linger in perception momentarily.
- Informational: Information remains accessible after the stimulus disappears.
Inverse Duration Effect: Longer lasting visual stimuli result in less persistent memory.
Inverse Intensity Effect: More intense stimuli lead to decreased persistence in iconic memory.

Visuo-Spatial Sketchpad

Described by Baddeley in 1986, it manages visual information and spatial manipulation.
Functions as part of working memory and is susceptible to interference.
Contains two components:
- Visual Cache: Stores form and color information.
- Inner Scribe: Holds spatial and movement data.

Mental Rotation and Spatial Representation

Mental rotation involves manipulating images in the mind, critical for tasks like chess and Tetris.
Boundary Extension: Tendency to visualize beyond the actual boundaries of an object.
Representational Momentum: The perception of motion continues in the mind even when observing a still image.

Mental Imagery

Defined as the ability to recreate sensory experiences without physical stimuli.
Two components identified:
- Imagining: Bringing an image into consciousness.
- Spatial Representation: Manipulating an image or concept mentally, applicable to other senses.
Not everyone can create detailed mental images, a realization noted by Francis Galton in 1883.
Initiation can occur accidentally, leading to discussions on its significance despite being non-observable.
Kosslyn's Theory: Mental images arise from long-term memory, retaining spatial properties over time.
