Syntax in pictures

It was hypothesised that pictures drawn to represent active and passive sentences would reflect this syntactic difference. Specifically, it was predicted that the reversal of the order in which the logical subject (LS) and the logical object (LO) occur in the change from active to passive form of sentence will affect the order in which they occur in their pictorial representations. A significant directional preference was found for placing the LO to the left of the LS in the pictorial representations of passive but not active sentences. This was discussed in terms of the marked status of the passive in relation to the active. In the case of sentences differing only in lexical marking there was no asymmetric directionality effect corresponding to that found for actives and passives. A significant tendency to match the surface order of the sentences in the pictures was found for both lexically marked and unmarked sentences. The possibility that other spatial or physical dimensions might be used to express syntactic and semantic factors in the pictorial representation of sentences is considered.
