The developmental course of multidimensional speech processing was examined in 80 children between 3 and 6 years of age and in 60 adults between 20 and 86 years of age. Processing interactions were assessed with a speeded classification task (Garner, 1974a), which required the subjects to attend selectively to the voice dimension while ignoring the linguistic dimension, and vice versa. The children and adults exhibited both similarities and differences in the patterns of processing dependencies. For all ages, performance for each dimension was slower in the presence of variation in the irrelevant dimension; irrelevant variation in the voice dimension disrupted performance more than irrelevant variation in the linguistic dimension. Trends in the degree of interference, on the other hand, showed significant differences between dimensions as a function of age. Whereas the degree of interference for the voice-dimension-relevant did not show significant age-related change, the degree of interference for the word-dimension-relevant declined significantly with age in a linear as well as a quadratic manner. A major age-related change in the relation between dimensions was that word processing, relative to voice-gender processing, required significantly more time in the children than in the adults. Overall, the developmental course characterizing multidimensional speech processing evidenced more pronounced change when the linguistic dimension, rather than the voice dimension, was relevant.Spoken words contain different types of information, such as auditory, phonetic, and semantic. Previous studies have suggested that these sources of information are processed together in a closely related manner by adults. Adult listeners, for example, cannot attend selectively to the voice dimension and ignore irrelevant variation in the linguistic dimension of speech, or vice versa. Instead, irrelevant variation in one dimension affects reaction time decisions in the other (Mullennix & Pisoni, 1990). Studies with auditory versions of "Stroop" stimuli (e.g., the word man spoken by a female voice; the word red printed in blue ink) (Stroop, 1935) revealed that adult listeners also cannot ignore irrelevant semantic content. Instead, semantic content systematically affects voice-gender reaction times. Performance is slower to Stroop targets representing conflict between voice and word dimensions, and faster to Stroop targets representing congruence between dimensions (Green & Barber, 1981, 1983. Such evidence implies that the voice and word dimensions are not processed independently (

In this paper, we extend on our exploratory study that examined mentors' conceptualizations and practices of mentoring preservice teachers in a residency program to develop a mentoring framework to guide mentors' approaches to mentoring preservice teachers in a year-long clinical experience. Our mentoring framework has the potential to make mentors consciously aware of their roles and purposes of mentoring throughout the year and within respective contexts. This metacognitive approach may help them to improve their practice and grow alongside their mentee. The Mentoring Framework for Mentoring is a tool that may be instrumental in developing mentors' deeper understanding of the roles and purposes of mentoring to promote quality guidance and support for mentees. Our instrument has the potential to inform teacher preparation programs regarding goals and expectations for mentors to develop more formal mentoring guidelines and expectations, to better support the professional development of both preservice teachers and mentors.

Purpose – The purpose of this paper is to examine preservice teachers’ perceptions of their learning and teaching experiences in a mentor's classroom during a year-long field-based placement in a high-need urban school. In addition, the authors sought to examine how the experiences contributed to their professional growth and development as future teachers. Design/methodology/approach – This qualitative study used constant comparative analysis (Strauss and Corbin, 1998) to examine preservice teachers’ responses to an open-ended questionnaire, program survey, and also in focus groups about their mentoring experiences. Findings – The findings provide insight into participants’ mentors’ influence during a year-long placement and into characteristics of effective mentoring that contributed to their growth. Major findings of preservice teachers’ mentoring experiences in a high-need urban setting reflected two dominant themes: experiencing a pedagogical fulcrum and navigating the tributaries of professionalism. Research limitations/implications – The study is limited by the small number of participants from one large public university and included only secondary preservice teachers enrolled in one residency program designed to prepare mathematics, science, and special education teachers. Caution should be taken against generalizing the findings, regarding preservice teachers’ learning and teaching experiences in a mentor's classroom, to resident teachers in other areas due to the small sample size and interpretation of the findings. Originality/value – The findings provide a different perspective about the mentoring process to that provided by previous studies because preservice teachers learned and taught in the mentor's classroom during one academic school year without being evaluated by the mentor. The findings illuminate preservice teachers’ professional growth fostered by their experiences and highlight characteristics of the mentor's influence that contributed to their development.
