Mind (source code)
= Mind
The <mind> is the collection of <mental processes> and capacities involved in <perception>, <attention>, <human memory>, thought, <emotion> and <consciousness>. In scientific <psychology>, these processes are investigated through specified tasks, reports, <behavior> and measurements of the <brain>. The <mind> is not one directly observed score: remembering a location and noticing a flash require different explanations and measurements.
A useful experiment separates available information from the ability to report it. In 1960, <George Sperling> used briefly displayed arrays of symbols and <partial report paradigms>. Asking for only part of a display helped test whether a limited whole report reflected unavailable visual information or a limit on retaining and reporting it. Tones could specify which portion to report after the display had ended.<The information available in brief visual presentations by George Sperling>[Introduction, p.1; partial-report experiments3–5; Experiment7, p.16, post-exposure tone instructions]{ref}
For an invented sampling example, suppose a display has three rows and a randomly selected row can be reported with an average of three correct symbols. Under equal sampling and accessibility assumptions, multiplying by three estimates nine available symbols across the display. That is an inference from a task, not a direct inspection of a mental store. Its assumptions must be checked, and a cue delivered much later can test how availability changes with time.
The example links <perception>, <sensory memory> and reporting while keeping them distinguishable. An <operational definition> identifies the actual response to be measured; <construct validity> asks whether the proposed interpretation of that response is justified. The scientific study of the <mind> becomes more precise when these connections are explicit.
