Book Description
Visual word recognition has been a central area of psychological inquiry over the past century. The current dissertation examines how visual word recognition changes as a function of age by focusing on the influence of word frequency, or how commonly a word is encountered. Word frequency is arguably the strongest predictor of visual word recognition performance across a variety of language tasks, and the most influential factor in models of language processing. All models of visual word recognition include a strong role for word frequency but often assume different underlying mechanisms, which produce differing predictions for age changes. Although there is already a literature examining word frequency effects in younger and older adults, these studies have produced inconsistent results, possibly due to procedural limitations and task-specific processes. This dissertation explores the influence of task and age on the word frequency effect, while directly examining individual differences (e.g., changes in vocabulary, vision, education) in order to better understand the mechanisms underlying word frequency effects. In contrast to the dichotomous approach of examining extreme groups of young and older adults, or extreme bands of word frequency, the present study examined both variables in a continuous manner. The primary finding is that the word frequency effect does not appear to change as a function of age across all three tasks considered. This finding is discussed in reference to previous inconsistent findings in the literature and important theoretical implications.

Book Description
Spoken Word Recognition covers the entire range of processes involved in recognizing spoken words - both in and out of context. It brings together a number of essays dealing with important theoretical questions raised by the study of spoken word recognition - among them, how do we understand fluent speech as efficiently and effortlessly as we do? What are the mental processes and representations involved when we recognize spoken words? How do these differ from those involved in reading written words? What information is stored in our mental lexicon and how is it structured? What do linguistic and computational theories tell us about these psychological processes and representations?The multidisciplinary presentation of work by phoneticians, linguists, psychologists, and computer scientists reflects the growing interest in spoken word recognition from a number of different perspectives. It is a natural consequence of the mediating role that lexical representations and processes play in language understanding, linking sound with meaning.Following the editors' introduction, the contributions and their authors are: Acoustic-Phonetic Representation in Word Recognition (David B. Pisoni and Paul A. Luce). Phonological Parsing and Lexical Retrieval (Kenneth W. Church). Parallel Processing in Spoken Word Recognition (William D. Marslen-Wilson). A Reader's View of Listening (Dianne C. Bradley and Kenneth I. Forster). Prosodic Structure and Spoken Word Recognition (Francois Grosjean and James Paul Gee). Structure in Auditory Word Recognition (Lyn Frazier). The Mental Representation of the Meaning of Words (P. N. Johnson-Laird). Context Effects in Lexical Processing (Michael K. Tanenhaus and Margery M. Lucas).Uli H. Frauenfelder is a researcher with the Max-Planck-Institut für Psycholinguistik, and Lorraine Komisarjevsky Tyler is a professor in the Department of Experimental Psychology at the University of Cambridge. Spoken Word Recognition is in a series that is derived from special issues of Cognition: International Journal of Cognitive Science, edited by Jacques Mehler. A Bradford Book.

Book Description
Component cognitive processes have played a critical role in the development of experimental aging research and theory in psychology as attested by articles published on this theme. However, in the last five to ten years, there has been a substantial increase in the number of articles attempting to isolate a single factor (or small subset of factors) responsible for age differences in information processing. This view of aging is frequently termed the complexity model of the generalized slowing model, the primary assumption being that age differences in cognition are due simply to a relatively larger performance decrement on the part of older adults (compared to younger adults) as task complexity increases. Because generalized complexity theorists have questioned the utility of using component cognitive processes as theoretical constructs, the editors feel it is time to restate why component cognitive processes are critical to any thorough understanding of age differences in cognition. Thus the present edited volume represents an attempt to demonstrate the utility of the process-specific approach to cognitive aging. Central to this effort are illustrations of how regression analyses may provide evidence for general slowing by maximizing explained variance while at the same time obscuring local sources of variance. The book concentrates on age differences in word and language processing, because these factors relate to reading which is a critical cognitive process used in everyday life. Furthermore, age differences in word and language processing illustrate the importance of taking component cognitive processes into consideration. The breadth of coverage of the book attests to the wide range of cognitive processes involved in word and language processing.

Book Description
This collection of papers and abstracts stems from the third meeting in the series of Sperlonga workshops on Cognitive Models of Speech Processing. It presents current research on the structure and organization of the mental lexicon, and on the processes that access that lexicon. The volume starts with discussion of issues in acquisition and consideration of questions such as, 'What is the relationship between vocabulary growth and the acquisition of syntax?', and, 'How does prosodic information, concerning the melodies and rhythms of the language, influence the processes of lexical and syntactic acquisition?'. From acquisition, the papers move on to consider the manner in which contemporary models of spoken word recognition and production can map onto neural models of the recognition and production processes. The issue of exactly what is recognised, and when, is dealt with next - the empirical findings suggest that the function of something to which a word refers is accessed with a different time-course to the form of that something. This has considerable implications for the nature, and content, of lexical representations. Equally important are the findings from the studies of disordered lexical processing, and two papers in this volume address the implications of these disorders for models of lexical representation and process (borrowing from both empirical data and computational modelling). The final paper explores whether neural networks can successfully model certain lexical phenomena that have elsewhere been assumed to require rule-based processes.
