Serial order and consonant-vowel structure in a graphemic output buffer model

We review features of the spelling errors of dysgraphic patients with "Graphemic Buffer Disorder" (GBD). We argue that the errors made by such patients suggest the breakdown of a system used to generate serial order in the output stages of spelling production, and we develop a model for this system based on an existing theory of sequential behaviour--"Competitive Queuing." We show that constraints on response categories may be straightforwardly applied during sequence production in such a model, and this enables us to account for the preservation of consonant-vowel status in the spelling errors of GBD patients. When the sequence generation process is disrupted by the addition of random noise the model shows the major features of GBD. The results are compared in detail against data from a number of patients.     

Training Young Children to Acknowledge Mixed Emotions

Abstract

The failure of children to acknowledge mixed, contradictory emotions is equally of developmental and clinical interest. Developmentally, children do not ordinarily acknowledge the existence of mixed emotions until late in middle childhood. Clinically, the failure to recognise mixed feelings toward others or self is a common presenting problem. The question addressed here is, how readily can such limitations be corrected in children of different ages. Two studies are reported showing that children as young as 6 and 7 years, who initially revealed little understanding of mixed feelings, showed more insight after a short training session. In Experiment 1. two groups of children were equated for their inability to diagnose the mixed feelings of a story character. Subsequently, both groups were presented with a second story containing a similar conflictual event, but only one group was prompted to consider the character's emotional reaction to each component of the conflict. Children in the prompted group were more accurate in diagnosing the character's emotional reaction at the end of the story than the control group, and they maintained their superiority on a post-test story where no prompts were given. Experiment 2 included a similar training procedure. but with a more stringent measure of post-test generalisation: Children were asked to describe or invent their own examples of emotionally charged conflictual situations. Four- and five-year-olds showed little benefit from the training session, but six- and seven-year-olds again showed considerable benefit. Taken together, the two experiments suggest that young school age children often fail to acknowledge mixed feelings because they engage in a cursory appraisal of the elements of an emotionally charged situation; highlighting the elements is sufficient to improve performance. Preschool children, however, appear to suffer from more basic limitations in their ability to integrate the relevant information.
