The Discriminant-Function as a Model for Perception

A feature utilization analysis of the perception of pattern class structure

“…The problem of how an 0 reduces input from the environment by the imposition of class structure has been dealt with in a perceptual context by other researchers (e.g., Rodwan & Hake, 1964;Imai & Garner, 1968;Handel & Preusser, 1969;Wing & Bevan, 1969;and Aiken & Brown, 1971). However, this problem is best considered as a special case of a more general question concerning the development of models which map the organism's attempts to structure his environment.…”

“…FenkerI, expanding upon the work of Rodwan and Hake (1964), has suggested a generalization of the Brunswik lens model to include discriminant analysis as a procedure for investigating feature utilization in complex pattern classification. The results of this study …”

Relational perception and modes of perceiver operation

“…Or he may, as did 01' attempt to partial out the aspect of stimulus variation that appears to be contextual rather than critical stimulus variation. This distinction may be restated as the distinction between an attempt to satisfy a coherence criterion of judgment (Hake et al, 1966;Rodwan & Hake, 1964), which leads to maximum subjective response consistency, and an attempt to satisfy an accuracy or veridical criterion.…”

Schematic concept formation: Feature measures and constraint redundancy as predictors

“…Moreover, this (A or B) was arbitrary, Ss were asked to ability was present during the first block of describe their categories in writing, and 20 trials under all but one condition. It is also apparent that, under most conditions, been discussed as both a data analysis the ability to do this is related to the level technique and as a model for the perceiver of constraint redundancy, i.e., the (e.g., Hake & Rodwan, 1966; Rodwan & association was generally higher for Hake, 1964) and offers a number of R c = 7fY% than for R, = 4fY% throughout advantages for the present problem. If we testing and especially during the first trial view the sets of patterns as points in a block.…”
