My research focuses on the development of reading ability and the perception of speech and involves undergraduate and graduate students as well as colleagues here and abroad. I am the director of an outreach program, HABLA, that seeks to promote school readiness through language-based interventions in the homes of over 350 socioeconomically and educationally disadvantaged preschoolers. I am also director of an outreach program, UCI Jumpstart, that is part of a national system for increasing English skills through college student mentoring of children in an after preschool program. To date both programs have been able to keep the primary language skills of disadvantaged Latino children within normal levels where scores of untreated peers drop one or more standard errors below normal. I am also a consultant for Scientific Learning, a software company that incorporates scientific research into computer-based training programs that promote language and reading. I have helped to create some of their recent products for the assessment and improvement of reading, Reading Edge and the award-winning Fastforward Reading series. For details on these, see: Fastforward Reading
I have also collaborated with people at Disney Learning to develop some of their books and applications (Doc McStuffins apps, Frozen interactive books, and 1000 First Words book) for early reading and language enhancement. See, for example: Doc McStuffins apps
My studies of reading attempt to characterize the inborn cognitive skills and the home and school experiences that work to support successful reading acquisition. For over twenty-five years I have studied how reading ability depends upon the integrity of certain spoken language capacities, particularly the 'phonological skills' by which the child perceives, remembers and manipulates the sounds of language. My stress upon the importance of phonological skills is particularly consonant with the current state of renewed emphasis on phonics-type methods of instruction for it shows that a key step in the child's realization of how an alphabetic writing system works as a representation of language is the realization that letters represent the sound patterns of language. With other colleagues, most notably Isabelle Liberman, I have also shown that phoneme awareness and phonological processing not only accompany present differences in reading ability, they actually presage them and can be successfully used a screening devices. With Judy Foy I am currently showing how many of the phonological abilities that we have found to distinguish good and poor readers (See Mann, 1998 for a review) can be approached before children enter school. With Joshua Ramirez I have studied the aural and visual speech processing skills of older dyslexic individuals to see whether the deficiencies can best be represented as auditory or phonological. My research strategy has encompassed studies of young children in America, Japan and most recently Germany (Mann and Wimmer, 2002) to determine how phonological awareness relates to cultural and educational experience as well as to spoken language and cognitive development. Some of my more recent work has involved studies of preschool literacy and phonological development in collaboration with Prof. Judy Foy. I have also compared the reading problems of autistic and dyslexic children with Sabine Huemer, and collaborated with her and other on the MRI abnormalities seen in autism. Finally, my research on reading turned to querying the role of morpheme awareness in older children's reading of complex words like 'healthy' and 'atomical'. With Maria Singson and Diana Mahony (see Mann, 2000), I have shown that at the same ages where the relation between phoneme awareness and reading becomes less intense, the relation between morpheme awareness increases.
In studying human speech perception, I have sought with Al Liberman and other colleagues to characterize how listeners recover phonemes from the acoustic waveforms and visual input that make up speech signals. I have worked most extensively on context effects, cases where the perception of a phoneme is effected by a part of the waveform or visual signal that would normally be associated with another phoneme. For example, in perceiving the sound 's', listeners make use of information in a following vowel, whether that vowel is heard or seen. In perceiving 'g' they make use of information in a preceding 'l' or 'r', whether the information is heard or seen (Fowler, Brown and Mann, 2000) and even Japanese perceivers are sensitive to this effect (Mann, 1987). We are using these effects to illustrate speech perception and its development that distinguishes universal "articulation recovery" processes from language specific "phonological" ones. With Miles Munro, Jim Flege and Yuki Takagi I looked into the question of critical periods in the formation of phonemic categories as well as in the occurrence of second language accents and in the perception of accentedness, where we looked at a continuous range of emersion age instead of arbitrary cuts. With Dhonam Pemba, I have helped to develop an app which has successfully used native productions of English to train the English acquisition of children living in China, where much of the English instruction is delivered by peole who are heavily accented English language learners.
