Two experiments examined whether the association between word-learning, nonword repetition, and immediate serial recall observed in children also exists in normal adults. The experiments also introduce a novel paradigm for studying word-learning. Experiment 1 studied the performance of 52 adults in nonword repetition, immediate serial recall, and(More)
Impairments in phonological processing have been associated with damage to the region of the left posterior superior temporal gyrus (pSTG), but the extent to which this area supports phonological processing, independent of semantic processing, is less clear. We used repetition priming and neural repetition suppression during functional magnetic resonance(More)
This article analyzes the relationship between skill learning and repetition priming, 2 implicit memory phenomena. A number of reports have suggested that skill learning and repetition priming can be dissociated from each other and are therefore based on different mechanisms. The authors present a theoretical analysis showing that previous results cannot be(More)
A growing body of research has emphasized the linkage between performance in immediate serial recall of lists, nonword repetition, and word learning. Recently, it has been reported that primacy and recency effects are obtained in repetition of individual syllables within nonwords (Gupta, in press). Five experiments examined whether such within -nonword(More)
The relationship between nonword repetition ability and vocabulary size and vocabulary learning has been a topic of intense research interest and investigation over the last two decades, following the demonstration that nonword repetition accuracy is predictive of vocabulary size (Gathercole & Baddeley, 1989). However, the nature of this relationship is not(More)
This paper discusses a perceptron model of the learning and assignment of linguistic stress, using data from nineteen human languages. First, we point out some interesting parallels between aspects of the model and the constructs and predictions of metrical phonology, the linguistic theory of stress. Second, we develop a novel analysis of linguistic stress(More)
We use connectionist modeling to develop an analysis of stress systems in terms of ease of learnability. In traditional linguistic analyses, learnability arguments determine default parameter settings based on the feasibilty of logically deducing correct settings from an initial state. Our approach provides an empirical alternative to such arguments. Based(More)
CONTEXT Tea is a rich source of fluoride (F(-)) and its consumption has become a cultural habit. F(-) available from tea might play important role in increasing total F(-) intake leading to dental fluorosis. AIMS To estimate F(-) concentration in different varieties of commercially available tea, in Mathura city, and to determine the change in(More)
AIM To estimate fluoride concentration in drinking water, cow's milk and buffalo's milk and to correlate the concentration of fluoride in cow's milk and buffalo's milk with varying levels of fluoride concentration in drinking water. MATERIALS AND METHODS Ten households having both cows and buffalo's were selected by convenience in each of the 3 zones(More)
A theory of the cognitive organisation of lexical processing, verbal short-term memory, and verbal learning is presented along with a summary of data that bear on this issue. We conceive of verbal STM as the outcome of processing that invokes both a specialised short-term memory and the lexical system. On this model, performance of verbal STM tasks depends(More)
