Speeded Classification

Using a speeded classification task, Walker and Walker (2012) demonstrated a cross-sensory correspondence between haptic size and surface brightness. Specifically, adult participants classified bright (dark) visual stimuli more quickly and accurately when this required them to press the smaller (bigger) of two response keys which were always hidden from view. The nature of the correspondence (i.e., small being aligned with bright), along with various aspects of the task situation, indicated that the congruity effect originated at later stages of information processing concerned with the semantic classification of stimuli and response selection. The study reported here provides additional evidence for the involvement of semantic coding. When the names of bright (white) edible substances (e.g., flour) and dark (black) inedible substances (e.g., soot) were classified according to their surface brightness, the same size–brightness congruity effect was observed. However, when the basis for classification of the substances was switched to their edibility, the congruity effect disappeared. It is therefore proposed that congruity effects based on cross-sensory correspondences can reflect interactions between the connotative meanings of elementary stimulus features (cf. Karwoski et al., 1942).

Speeded Classification

The study springs from views on attentional deficits in retarded performers. Three experiments are reported in which educationally sub-normal (mild) category pupils and average ability pupils matched with them for mental age perform a speeded classification of cards on the basis of an enumeration of a group of items on each card. This group may be the total of the items on the card or a selected part of that total. Interest focuses upon the relationship between performance in the selective situation and the form or structure of the item group. It is argued initially that attentional patterns may be expected to vary in relation to the specific structure of the information available and the way the performer appreciates that structure. The results support this notion. ESN(M) subjects perform in a similar fashion to the matched group, even given selective instructions, when what must be counted is the whole of a vertical linear series of items. However, when what must be counted is in the form of a part of a vertical linear item series, the performance of the ESN(M) group is significantly slower than that of the matched group. In addition the matched group appear more sensitive to discontinuity within the vertical item series while the ESN(M) group may have a less differentiated approach to such information founded mainly on the appreciation of verticality. It is suggested that aspects of information available to performers must be studied in relation to the kind of whole the particular performer takes the information to be. Although retardates do not carry appropriate structural expectations from situation to situation, suitable organisation of information can be appreciated, leading to more successful performance.
