Description
Summary:A series of three exploratory experiments sought to compare and contrast two broad classes of theory pertaining to visual information pick-up. One theoretical approach, exemplified by Keele and Neill (1978) and by Treisman (1977) emphasizes the relatively passive, parallel development of information codes, with subsequent attentional integration of contiguous codes into a percept. Another theoretical approach, exemplified by Broadbent (1977a) emphasizes the relatively active, sequential, recursive interrogation of a visual display in which the pick-up of each piece of information guides the perceptual system in its quest for more information. The manner in which separable attributes of visual information are picked up and combined was studied by manipulating the roles of different attributes in a rapid serial visual presentation (RSVP) paradigm. Observers were asked to report the name of a letter in a specified target colour; to report the colour of a specified target letter; to report the colour of a specified target numeral embedded in a list of letters; to report the colour of an unspecified numeral embedded in a list of letters; and to perform the latter two tasks without knowing in which of two alternating spatial positions the target might appear. Examination of the patterns of mis-combinations of attributes from target and non-target stimuli yields evidence both for and against each theoretical position, and suggests that the two might better be considered as modes of processing available to the perceptual system, rather than as intrinsic properties of that system.
