This paper describes a number of simulations whichshow that SRN representations exhibit interactionsbetween m e m o r y and sentence and clauseboundaries reminiscent of effects described in theearly psycholinguistic literature (Jarvella, 1971;Caplan, 1972). Moreover, these effects can beaccounted for by the intrinsic properties of srnrepresentations without the need to invoke externalmemory mechanisms, as has conventionally beendone.

A connectionist attentional-shift model of eye-m o v e m e n t control (CASMEC) in reading is described.T h e model provides an integrated account of a rangeof saccadic control effects found in reading, such asword-skipping, refixation, and of course normalsaccadic progression.

This paper provides a short overview of current issues in research on continuous reading in non-Roman orthographies. At the same time it also serves as an introduction to the present Reading and Writing Special Issue on this topic. The main questions examined in the contributions to this volume are closely related to issues that have been central to research debates on reading in English, German and French. However, we argue that these innovative approaches to the dynamics of reading in Chinese, Japanese and Korean go far beyond a simple comparative research strategy. Instead, by illuminating phenomena like word segmentation, parafoveal processing and semantic analysis from their unique perspectives, they provide valuable insights into the more general question of to what extent information processing in reading is universal as opposed to language specific. Moreover, we expect that these initial studies will trigger more basic research on non-alphabetic reading, providing a foundation for useful application.

A model for predicting student performance on introductory programming modules is presented. The model uses attributes identified in a study carried out at four third-level institutions in the Republic of Ireland. Four instruments were used to collect the data and over 25 attributes were examined. A data reduction technique was applied and a logistic regression model using 10-fold stratified cross validation was developed. The model used three attributes: Leaving Certificate Mathematics result (final mathematics examination at second level), number of hours playing computer games while taking the module and programming self-esteem. Prediction success was significant with 80% of students correctly classified. The model also works well on a per-institution level. A discussion on the implications of the model is provided and future work is outlined. (Contains 5 tables.)

In her Behavioral and Brain Sciences target article, Greenfield (1991) proposed that early in a child's development Broca's area may serve the dual function of coordinating object assembly and organizing the production of structured utterances. As development progresses, the upper and lower regions of Broca's area become increasingly specialized for motor coordination and speech, respectively. This commentary presents a connectionist simulation of aspects of this proposal. The results of the simulation confirm the main thrust of Greenfield's argument and suggest that an important impetus for the developmental differentiation in Broca's area may be the increasing complexity of the computational demands made upon it.
