Corticothalamic Projections Deliver Enhanced Responses To Medial Geniculate Body As A Function Of The Temporal Reliability Of The Stimulus, Srinivasa P Kommajosyula, Edward L Bartlett, Rui Cai, Lynne Ling, Donald M Caspary Dec 2021

Corticothalamic Projections Deliver Enhanced Responses To Medial Geniculate Body As A Function Of The Temporal Reliability Of The Stimulus, Srinivasa P Kommajosyula, Edward L Bartlett, Rui Cai, Lynne Ling, Donald M Caspary

Articles

Ageing and challenging signal-in-noise conditions are known to engage the use of cortical resources to help maintain speech understanding. Extensive corticothalamic projections are thought to provide attentional, mnemonic and cognitive-related inputs in support of sensory inferior colliculus (IC) inputs to the medial geniculate body (MGB). Here we show that a decrease in modulation depth, a temporally less distinct periodic acoustic signal, leads to a jittered ascending temporal code, changing MGB unit responses from adapting responses to responses showing repetition enhancement, posited to aid identification of important communication and environmental sounds. Young-adult male Fischer Brown Norway rats, injected with the inhibitory …


Eye-Tracking As A Window Into Assembled Phonology In Native And Non-Native Reading, Katherine I. Martin, Alan Juffs Jan 2021

Eye-Tracking As A Window Into Assembled Phonology In Native And Non-Native Reading, Katherine I. Martin, Alan Juffs

Articles

The past 30 years of reading research has confirmed the importance of bottom-up processing. Rather than a psycholinguistic guessing game (Goodman, 1967), reading is dependent on rapid, accurate recognition of written forms. In fluent first language (L1) readers, this is seen in the automatic activation of a word’s phonological form, impacting lexical processing (Perfetti & Bell, 1991; Rayner, Sereno, Lesch & Pollatsek, 1995). Although the influence of phonological form is well established, less clear is the extent to which readers are sensitive to the possible pronunciations of a word (Lesch & Pollatsek, 1998), …


English Word And Pseudoword Spellings And Phonological Awareness: Detailed Comparisons From Three L1 Writing Systems, Katherine I. Martin, Emily Lawson, Kathryn Carpenter, Elisa Hummer Jul 2020

English Word And Pseudoword Spellings And Phonological Awareness: Detailed Comparisons From Three L1 Writing Systems, Katherine I. Martin, Emily Lawson, Kathryn Carpenter, Elisa Hummer

Articles

Spelling is a fundamental literacy skill facilitating word recognition and thus higher level reading abilities via its support for efficient text processing (Adams, 1990; Joshi et al., 2008; Perfetti and Stafura, 2014). However, relatively little work examines second language (L2) spelling in adults, and even less work examines learners from different first language (L1) writing systems. This is despite the fact that the influence of L1 writing system on L2 literacy skills is well documented (Hudson, 2007; Koda and Zehler, 2008; Grabe, 2009). To address this shortcoming, this study collected data on real word spelling, pseudoword spelling, and phonological awareness …


The Grammatical Class Effect Is Separable From The Concreteness Effect In Language Learning, Katherine I. Martin, Natasha Tokowicz May 2020

The Grammatical Class Effect Is Separable From The Concreteness Effect In Language Learning, Katherine I. Martin, Natasha Tokowicz

Articles

Typically concrete words are learned better than abstract words (Kaushanskaya & Rechtzigel, 2012), and nouns are learned better than verbs (Kauschke & Stenneken, 2008). However, most studies on concreteness have not manipulated grammatical class (and vice versa), leaving the relationship between the two unclear. Therefore, in two experiments we examined the effects of grammatical class and concreteness simultaneously in foreign language vocabulary learning. In Experiment 1, English speakers learned ‘foreign language’ words (English pseudowords) mapped to concrete and abstract nouns and verbs. In Experiment 2, English speakers learned German words with the same procedure. Overall, the …


The Flipped Classroom In Esl Teacher Education: An Example From Call, Yuyen Lee, Katherine I. Martin Jan 2020

The Flipped Classroom In Esl Teacher Education: An Example From Call, Yuyen Lee, Katherine I. Martin

Articles

The flipped classroom is one of many technology-enhanced teaching strategies. In this approach, students are responsible for initial learning at home (often via instructional videos) and class time is used for problem-solving and activities to deepen understanding. Although research on and use of the flipped classroom in language education is growing, little work has examined its use in teacher education, particularly for language teachers. To address this gap, this study examined the flipped classroom through the eyes of pre-service language teachers to reveal what hinders them from or encourages them to adopt this approach. Data were collected from students in …


The Impact Of L1 Writing System On Esl Knowledge Of Vowel And Consonant Spellings, Katherine I. Martin Jan 2017

The Impact Of L1 Writing System On Esl Knowledge Of Vowel And Consonant Spellings, Katherine I. Martin

Articles

Orthographic knowledge, the general ability to learn, store, and use information about the orthographic form of words (Stanovich & West, 1989), is a crucial skill for supporting literacy. Although the development of first language (L1) orthographic awareness is impacted by the characteristics of a learner’s L1 writing system, relatively little is known about what impact the L1 may have on second language (L2) orthographic awareness. In this study, English language learners from three L1s (French, Hebrew, Mandarin Chinese), plus L1 English speakers, were tested on their English spelling knowledge using a word-pseudohomophone discrimination task. In addition to allowing for the …


Cyclicity Versus Movement: English Nominalization And Syntactic Approaches To Morpho-Phonological Regularity, Jeffrey Punske Mar 2016

Cyclicity Versus Movement: English Nominalization And Syntactic Approaches To Morpho-Phonological Regularity, Jeffrey Punske

Articles

In this paper, I show that Embick’s (2010) cyclic head approach to regular morphology alone cannot account for the freely available variations in the realization of nominalizers in English nominalizations involving overt verbalizers. Instead, I offer an account of the regularity effects using the technology of Local Dislocation (Embick and Noyer 2001, Embick and Marantz 2008, Embick 2007a, 2007b). Using this analysis, I derive both the variable nominalization patterns and the restrictions on particles and results in derived nominals from Sichel (2010). By treating regularity as the by-product of extant morphosyntatic operations, we can better explain the distribution of regular …


Delayed Valuation: A Reanalysis Of Goal Features, “Upwards” Complementizer Agreement, And The Mechanics Of Case, Vicki Carstens Jan 2016

Delayed Valuation: A Reanalysis Of Goal Features, “Upwards” Complementizer Agreement, And The Mechanics Of Case, Vicki Carstens

Articles

There are at least four opposing views on the directionality and configuration of Agree relations. In mainstream Minimalism, Agree is strictly downward “probing” (Chomsky 2000, 2001, Boskovic 2007, Epstein & Seely 2006), but some recent works argue instead that Agree always looks upwards (Zeijlstra 2012; Wurmbrand 2012). A third perspective takes agreement to follow from the Spec, head configuration (Koopman 2006; and see Chomsky’s 2013 labeling through shared prominent features), and under a fourth proposal, the directionality of Agree varies parametrically (Baker 2008). While each of these approaches has some empirical support, none achieves the strict conceptual necessity that is …

The Roles Of Phonological Short-Term Memory And Working Memory In L2 Grammar And Vocabulary Learning, Katherine I. Martin, Nick C. Ellis Jan 2012

The Roles Of Phonological Short-Term Memory And Working Memory In L2 Grammar And Vocabulary Learning, Katherine I. Martin, Nick C. Ellis

Articles

This study analyzed phonological short-term memory (PSTM) and working memory (WM) and their relationship with vocabulary and grammar learning in an artificial foreign language. Nonword repetition, nonword recognition, and listening span were used as memory measures. Participants learned the singular forms of vocabulary for an artificial foreign language before being exposed to plural forms in sentence contexts. Participants were tested on their ability to induce the grammatical forms and to generalize the forms to novel utterances. Individual differences in final abilities in vocabulary and grammar correlated between 0.44 and 0.76, depending on the measure. Despite these strong associations, the results …


Learning Disabled Student Needs Met Through Curriculum Redesign Of The Illinois Agricultural Education Core Curriculum, Seburn L. Pense, Dennis G. Watson, Dexter B. Wakefield Jan 2010

Learning Disabled Student Needs Met Through Curriculum Redesign Of The Illinois Agricultural Education Core Curriculum, Seburn L. Pense, Dennis G. Watson, Dexter B. Wakefield

Articles

This quasi–experimental pilot study included agricultural education students with Specific Learning Disabilities (SLD) in five high schools in the federally designated economically distressed area called the Illinois Delta Region. A unit of instruction taken from the existing 165 units of The Illinois Core Curriculum for Agriculture was redesigned in a manner appropriate to SLD students. Students from the five selected programs were randomly assigned to treatment and control groups. Results from pre– and posttests in this study found the redesigned curriculum for SLD students effectively increased learning for both SLD and traditional students.


“We Are Going To Rape You And Taste Tutsi Women”: Rape During The 1994 Rwandan Genocide, Christopher W. Mullins Nov 2009

“We Are Going To Rape You And Taste Tutsi Women”: Rape During The 1994 Rwandan Genocide, Christopher W. Mullins

Articles

Over the past decades, scholars have paid greater attention to sexual violence, in both theorization and empirical analysis. One area which has been largely ignored, however, is the sexual violence during times of armed conflict. This paper examines the nature and dynamics of sexual violence as it occurred during the 1994 Rwandan genocide. Drawing upon testimonies given to the International Criminal Tribunal for Rwanda (ICTR), descriptions of rapes--both singular and mass—were qualitatively analyzed. In general, three broad types of assaults were identified: opportunistic, assaults which seemed to be a product of the disorder inherent within the conflict; episodes of sexual …


Managing Indigenous Knowledge And Traditional Cultural Expressions: Is Technology The Solution?, Amber T. Burtis Jul 2009

Managing Indigenous Knowledge And Traditional Cultural Expressions: Is Technology The Solution?, Amber T. Burtis

Articles

This paper discusses current issues surrounding the management of indigenous knowledge (IK) and traditional cultural expressions (TCEs) in libraries, archives and other cultural institutions. It addresses the need for: (1) ethical policies for the management of these knowledge systems, (2) critical approaches to the dominant library paradigm of information management, (3) recent efforts by the World Intellectual Property Organization and the American Library Association to craft policy on this topic, and (4) the need for and examples of collaboration with indigenous communities. Implications for social change with the implementation of socially responsible management systems are also considered.
