Structure and Content in Language Production: A Theory of Frame Constraints in Phonological Speech Errors

Theories of language production propose that utterances are constructed by a mechanism that separates linguistic content from linguistic structure, Linguistic content is retrieved from the mental lexicon, and is then inserted into slots in linguistic structures or frames. Support for this kind of model at the phonological level comes from patterns of phonological speech errors. W present an alternative account of these patterns using a connectionist or parallel distributed proceesing (PDP) model that learns to produce sequences of phonological features. The model's errors exhibit some of the properties of human speech errors, specifically, properties that have been attributed to the action of phonological rules, frames, or other structural generalizations.     

Is knowledge of family history related to psychosocial functioning? Comparison of adolescents living in institutional care and adolescents living with their biological families

We tested adolescents growing up in institutional care and adolescents living with their birth families using the ‘Do you know?’ scale and other measures of psychosocial functioning. We found that children living in group homes knew significantly less of their family history, exhibited more behavioural problems and had a more external locus of control. Moreover, the correlations between self-esteem and knowledge of family history were significantly different between the groups. This may suggest that the contribution of the knowledge of family history to self-esteem is different depending on the quality of family history. We also found a significant correlation between locus of control and behavioural problems for the children in institutional care, but not children living with their birth families, which may indicate that their behavioural problems may partially stem from the sense of lack of control over their lives.
