    Study Notes

    Selective Attention, Categorisation & Generalisation

    • We categorise items based on features that are salient (attention-grabbing) or relevant.
    • Selective attention influences generalisations about new items.

    Shepard, Hovland, & Jenkins (1961)

    • Investigated how people learn categories with varying defining features.
    • Participants learned to sort objects into categories based on color or shape.
    • Over time, participants learned to focus on only the relevant dimension (e.g., color for candle/lightbulb), making differences in that dimension more pronounced and differences in other dimensions less noticeable.

    Category Learning Difficulty

    • Paying attention to one dimension accentuates differences on that dimension.
    • Paying more attention to one dimension results in less attention to other dimensions, making objects appear more similar on unattended dimensions.

    Garner (1974)

    • Investigated how people learn categories when features are correlated, uncorrelated, or orthogonal (independent).
    • Participants learned to sort objects based on line position and saturation.
    • Performance was worse when features were correlated, suggesting that selective attention to one dimension can interfere with learning about other dimensions.

    Lin & Little (2023)

    • Investigated how the number of stimuli in a category affects learning.
    • Increasing the number of stimuli within a category makes the categories effectively all the same along irrelevant dimensions.
    • This highlights the importance of selective attention to relevant dimensions for efficient category learning.

    Nosofsky (1986)

    • Investigated how people represent categories using transfer tests.
    • Participants were trained to classify stimuli based on two dimensions.
    • Transfer performance was measured by how well they classified novel stimuli.
    • Results showed a strong relationship between generalization and similarity, suggesting that people represent categories based on the similarity of features.

    Benefits of Categorisation

    • Reduces the complexity of the environment by simplifying information.
    • Provides a basis for deciding appropriate action, as categories allow for rapid decision-making.
    • Allows for identifying ambiguous or missing attributes by using shared features within a category.
    • Enables generalisation to new examples by inferring properties based on category membership.
    • Enables the organisation and relation of classes of objects and events through hierarchical structures (superordinate, basic, subordinate levels).

    Importance of Basic Level Categories

    • Basic level categories are the most informative, having a large number of correlated features.
    • Basic level categories often correspond to nouns and adjectives in language.

    Grounding by Similarity

    • Natural categories: based on shared features (e.g., birds, apples).
    • Man-made artifacts: based on shared function and design (e.g., chairs, clocks).
    • Ad hoc categories: based on a common goal (e.g., things to take camping).
    • Abstract schema or metaphors: based on shared metaphorical qualities (e.g., events in which kindness is repaid with cruelty).

    Importance of Categorisation

    • Plays a crucial role in making sense of the world by simplifying information, structuring knowledge, and allowing for rapid decision-making and generalisation.
    • It enables communication, social interaction, and learning across various domains.
