| Notes |
|
A fascinating (and early -- c.50 years ago) work that summarises how humans perceive the world aound them. Briefly, for Bruner, perception is simply a matter of categorisation: matching stimulus to category.

p.123
"Perception involves an act of categorization. Put in terms of the antecedent and subsequent conditions from which we make our inferences, we stimulate an organism with some appropriate input and he responds by referencing the input to some class of things or events."

"...all perceptual experience is necessarily the end product of a categorization process."

Bruner uses the term predictive veridicality: "By predictive veridicality I mean simply that perceptual categorization of an object or event permits one to "go beyond" the properties of the object or event perceived to a prediction of other properties of the object not yet tested. The more adequate the category systems constructed for coding environmental events in this way, the greater the predictive veridicality that results."

Discussing the accessibility of categories (how readily categorisation is performed): "...perceptual readiness or accessibility performs two functions: to minimize the surprise value of the environment by matching category accessibility to the probabilities of events in the world about one, and to maximize the attainment of sought-after objects and events."

| p.133 "Where accessibility of categories reflects environmental probabilities, the organism is in the position of requiring less stimulus input, less redundancy of cues for the appropriate categorization of objects." Added by: Mark Grimshaw-Aagaard |

pp.135–137
A section dealing with expectancy. Bruner suggests that expectancy of encountering events or objects in any context "preactivates a related array of categories" (p.137) leading to a heightened state of perceptual readiness.

| p.142 "The ability to use minimal cues quickly in categorization of the environment is what gives the organism its lead time in adjusting to events. Pause and close inspection inevitably cut down on this precious interval for adjustment." Added by: Mark Grimshaw-Aagaard |
| Paraphrases |
| p.125 While discussing an organism's ability to distinguish sensations between different modalities (e.g. vision and hearing), Bruner suggests that this ability and the modalities may not be so disjunct as first thought -- cf synesthaesia. Added by: Mark Grimshaw-Aagaard |
