Strategic control over rate of processing in word reading: A computational investigation
نویسندگان
چکیده
It has recently been proposed that the time course of lexical processing can be influenced by strategic control factors in word reading. In the current study, a specific hypothesis of control, rate of processing, was implemented in three simulations of word reading. Simulation results showed that, by modulating the dynamic of processing, the control parameter input gain can account for effects of pressure for speed and stimulus blocking on naming performance. Results showed also that, to account for error patterns found in the tempo-naming task (Kello & Plaut, 2000), the influence of lexical knowledge must be strengthened relative to the standard dual-pathway architecture. Two methods of strengthening the influence of lexical knowledge are demonstrated: input gain used as a mechanism of route emphasis, or integration of the two commonly proposed pathways from orthography to phonology. 2002 Elsevier Science (USA).

Strategic Control Over Rate of Processing in Word Reading: A Computational Investigation of the Tempo-Naming Task
In reading, it is generally believed that the computation of phonology is accomplished by the coordination of a lexical pathway and a sub-lexical pathway. It has been proposed that the influence of each pathway can be strategically modulated, but this proposal has been challenged by alternative mechanisms of strategic control, in particular, mechanisms of control over response criteria or rate ...
متن کاملRUNNING HEAD: Strategic Control in Naming Coarse Strategic Control in Word Reading: Evidence from Tempo Naming and a Computational Model
We investigate the hypothesis that lexical and rule knowledge can be strategically emphasized in word naming based on task demands, in contrast with the hypothesis that a time criterion to respond can be strategically manipulated. We devised the tempo naming to investigate the extent to which readers have precise control over response initiation in naming. Relative to baseline performance in th...
متن کاملProcessing of Lexical Bundles by Persian Speaking Learners of English
Formulaic sequence (FS) is a general term often used to refer to various types of recurrent clusters. One particular type of FSs common in different registers is lexical bundles (LBs). This study investigated whether LBs are stored and processed as a whole in the mind of language users and whether their functional discourse type has any effect on their processing. To serve these objectives, thr...

Background: Various factors influence the natural processing of words. The present study sought to investigate the effect of the regularity variable on the reading of words. Objectives: The participants in the study were 50 normal and 5 aphasic people (of Broca, transcortical motor and conduction aphasia types) who were selected through convenience sampling method. Materials & Methods: It was...
متن کاملOn the interaction between linguistic and pictorial systems in the absence of semantic mediation: evidence from a priming paradigm.
Use of the letter search task in the context of the priming paradigm has proved to be an invaluable tool for the investigation of the strategic control of processes involved in word recognition. In particular, previous findings that letter search on a prime word interferes with the priming of semantically/associatively related targets, but not with the priming of either identical or morphologic...
