In contrast, hierarchical incrementality assumes early encoding of relational information after picture onset and thus allows for top-down control of linguistic encoding: the second character should be easier to add to the developing sentence when formulation is supported by a conceptual framework, so speakers may initate gaze shifts to the second character earlier in higher-codability than lower-codability
events. Finally, if changes in formulation are INCB024360 clinical trial observed across events differing in codability of characters and actions, interactions between character codability and event codability should highlight the relative sensitivity of the production system to non-relational and relational
variables. On the one hand, if the production system generally click here favors linearly incremental planning, the ease of encoding non-relational information should control the extent to which relational properties of an event also influence formulation: character codability should be the strongest predictor of formulation, allowing effects of event codability to be observable relatively late in the formulation process or only when characters are difficult to encode (i.e., in events where speakers may need to fall back on other types of information to formulate their sentences). On the other hand, if the production system generally favors hierarchically incremental planning, event codability should control the extent to which properties of agents and patients also influence formulation: character codability should play a weak role in formulation for high-codability events and a stronger role for low-codability events (i.e., events where speakers may need to fall back on non-relational information to formulate their
sentences). Message-level planning involves encoding of non-relational and relational information, so the mapping of conceptual representations onto language also takes place via processes responsible for encoding two types of information. Production models agree that the mapping from concepts to language occurs via the process of lemma selection (for content words) and function assignment (for links between concepts, thematic roles, and structure-building procedures). Arachidonate 15-lipoxygenase In this sense, words and structures carry non-relational and relational information respectively: nouns (like dog and mailman) describe referents, rather than the relationship between referents, whereas structures (like actives and passives) express these relationships, irrespective of the identity of the referents. 2 Since speakers are able to pass on conceptual information to linguistic encoding as soon as it becomes available, both lexical and structural processes can be expected to systematically influence the timecourse of formulation.
