Separating the contributions of hearing, lexical knowledge and speech production to speech perception scores in children with hearing impairments.

Open-set word and sentence speech-perception test scores are commonly used as a measure of hearing abilities in children and adults using cochlear implants and/or hearing aids. These tests are usually presented auditorily with a verbal response. In the case of children, scores are typically lower and more variable than for adults with hearing impairments using similar devices. It is difficult to interpret children's speech-perception scores without considering the effects of lexical knowledge and speech-production abilities on their responses. This study postulated a simple mathematical model to describe the effects of hearing, lexical knowledge, and speech production on the perception test scores for monosyllabic words by children with impaired hearing. Thirty-three primary-school children with impaired hearing, fitted with hearing aids and/or cochlear implants, were evaluated using speech-perception, reading-aloud, speech-production, and language measures. These various measures were incorporated in the mathematical model, which revealed that performance in an open-set word-perception test in the auditory-alone mode is strongly dependent on residual hearing levels, lexical knowledge, and speech-production abilities. Further applications of the model provided an estimate of the effect of each component on the overall speech-perception score for each child.

Phonology and lexicon in a cross-linguistic perspective : the importance of phonetics – a commentary on Stoel-Gammon's 'relationships between lexical and phonological development in young children'

In her interesting article, Stoel-Gammon (this issue) reviews studies concerning the interactions between lexical and phonological development. While the focus of the review is on vocabulary production from children acquiring American English, she also suggests that cross-linguistic research be undertaken to examine how universal and language-specific properties affect the interaction between lexical and phonological acquisition. In this regard, Stoel-Gammon referred to the study of Bleses et al. (2008) who found differences in receptive vocabulary development across languages, based on norming studies for the Communicative Development Inventories (Fenson, Marchman, Thal, Dale, Reznick & Bates, 2007). Bleses et al. showed that Danish children were slower in the early comprehension of words (and phrases). It was hypothesized that the phonetic structure of Danish may account for the difference in receptive vocabulary skills in this population (Bleses & Basbøll, 2004).

What were they thinking? An exploration of child sexual offenders' beliefs using a lexical decision task

Cognitive distortions have been afforded a key role in the offending behaviour of child sexual offenders. While the mechanisms underlying cognitive distortions are not fully understood, they are generally thought to reflect entrenched beliefs that distinguish child sexual offenders from other individuals. We investigated this hypothesis using a robust experimental technique called the lexical decision task. Child sexual offenders, offender controls, and non-offender controls completed a lexical decision task in which they responded to words that completed sentences in either an offence-supportive or nonoffence-supportive manner. Contrary to predictions, child sexual offenders did not respond faster to words that were consistent with offence-supportive beliefs, relative to controls. However, they did show accelerated recognition for word stems supporting external locus of control beliefs. These results highlight the need to use cognitive experimental methods to study child sexual offenders' beliefs, and the importance of investigating potential alternative drivers of cognitive distortions.

Borrowings; or ways of making poetry by taking, working and returning: a study in creative practice

The collaborative poetry project ‘Borrowings’ investigates and theorises some of the processes of poetic composition. Two collaborators, by making use of incepts from each other's work, have generated new poems by exploring the nature of intertextual genesis. This paper presents key ideas generated by this activity and, in doing so, applies Deleuze's analysis of games to its consideration of the nature of poetic composition, along with his contention that ‘[t]o pass to the other side of the mirror is to pass from the relation of denotation to the relation of expression … It is to reach a region where language no longer has any relation to that which it denotes’. The project explores some of the ways in which poetry makes ‘sense’, both to the writer and reader; as well as questioning the extent to which poetry depends on its author's ‘decision’ about what to write. It also teases out some of the implications for how we understand authorship if authorial decisions may be generated by incepts of one kind or another that occur to the poet apparently randomly, or may be given to them by a line or phrase that they encounter while reading. This paper's ultimate wager, and one put to the test in the project itself, is that limitation has an expansive effect on the generation of creative work.

Lexical and syntactic transfer in writing: a pilot study of two Chilean learners of EFL

Transfer is crucial during the learning and acquisition of a Second Language (L2) and can affect learners' production and reception at all stages of learning. The ·process of transfer can be explained as the use of structures or lexical items which are concurrent with or deviant from the target language, but which are in fact copies of structures or lexical items from the learner's First Language (L1) (Larranaga, Treffers-Daller, Tidball & Ortega, 2011). Transfer is a common occurrence and as such, it' is crucial to acknowledge its use and utility by learners during the process of second language learning and acquisition. Transfer is not always negative; structures and lexical items from a learner's L1 may transfer into their L2 with accuracy and naturalness. This may be particularly the case where a learner is acquiring a language which is cognate with their L1 and as such has a high degree of reciprocity or overlap. However, even cognate languages contain distinctive structures and words which L2 learners must identify as reciprocal or non-reciprocal in order to improve their writing by avoiding negative transfer. Transfer often occurs via translation, particularly for lexical items. Adult L2 learners rely on L1 translation particularly for lexical processing and production; learners' knowledge of L1 informs their use of L2 vocabulary to varying degrees depending on their proficiency (Jiang, 2004).

Priming vs. rhyming : orthographic and phonological representations in the left and right hemispheres

The right cerebral hemisphere has long been argued to lack phonological processing capacity. Recently, however, a sex difference in the cortical representation of phonology has been proposed, suggesting discrete left hemisphere lateralization in males and more distributed, bilateral representation of function in females. To evaluate this hypothesis and shed light on sex differences in the phonological processing capabilities of the left and right hemispheres, we conducted two experiments. Experiment 1 assessed phonological activation implicitly (masked homophone priming), testing 52 (M = 25, F = 27; mean age 19.23 years, SD 1.64 years) strongly right-handed participants. Experiment 2 subsequently assessed the explicit recruitment of phonology (rhyme judgement), testing 50 (M = 25, F = 25; mean age 19.67 years, SD 2.05 years) strongly right-handed participants. In both experiments the orthographic overlap between stimulus pairs was strictly controlled using DICE [Brew, C., & McKelvie, D. (1996). Word-pair extraction for lexicography. In K. Oflazer & H. Somers (Eds.), Proceedings of the second international conference on new methods in language processing (pp. 45–55). Ankara: VCH], such that pairs shared (a) high orthographic and phonological similarity (e.g., not–KNOT); (b) high orthographic and low phonological similarity (e.g., pint–HINT); (c) low orthographic and high phonological similarity (e.g., use–EWES); or (d) low orthographic and low phonological similarity (e.g., kind–DONE). As anticipated, high orthographic similarity facilitated both left and right hemisphere performance, whereas the left hemisphere showed greater facility when phonological similarity was high. This difference in hemispheric processing of phonological representations was especially pronounced in males, whereas female performance was far less sensitive to visual field of presentation across both implicit and explicit phonological tasks. As such, the findings offer behavioural evidence indicating that though both hemispheres are capable of orthographic analysis, phonological processing is discretely lateralised to the left hemisphere in males, but available in both the left and right hemisphere in females.

Sexual content induced delay : a re-examination investigating relation to sexual desire

This article reports the utility of an information processing approach to examine whether there is a relationship between sexual content induced delay and levels of sexual desire as determined by self-report questionnaires. We tested this idea using a partial replication of the J. H. Geer and H. S. Bellard (1996) protocol demonstrating sexual content induced delay (SCID) in responding to sexual versus neutral words. In addition, the experiment examined whether SCID was different in people with varying levels of sexual desire. It was hypothesized that persons with low levels of sexual desire might respond more slowly to sexual word cues than others. Words with equal frequency of usage and similar word length were chosen from among those used in the Geer and Bellard study. The experiment was conducted with 171 volunteers who completed sexual desire questionnaires, lexical decision making tasks, and word ratings. The SCID effect was demonstrated by both men and women in the study with no significant variation between the sexes. In accordance with prediction, it was found that persons with lower levels of sexual desire responded more slowly to sexual stimuli than other participants, and rated sexual words as less familiar, less acceptable, and less positive emotionally to them. These findings have implications for understanding how emotional content contributes to SCID. They also suggest that further exploration of these ideas, perhaps using other stimulus modalities, may be helpful in advancing understanding of responses to sexual cues, and the potential implications that may have in better understanding sexual desire.

Turning the pages : adolescents, schools and reading

This study focuses on adolescents and reading. My premise is that adolescents develop a reading identity which is influenced by an existent reading culture to which they are exposed. This existent reading culture can be influenced in particular by schooling, family and the opinions of peers. One major influence is the classroom. Within the English curriculum, what criteria do English teachers use for selection of set texts and are there differences in criteria in all-boy/all girl and co-educational schools? I reflected on the prevailing perceptions that relate to gender, masculinity and popular culture which can affect what it means to be a boy, literate, and a reader of fictional texts. My first folio piece examines adolescents’ reading within five secondary schools, including an all-boy school, to ascertain whether boys in single-sex schools read more fictional texts and whether they enjoy reading more than their counterparts in co-educational schools. Authors are frequently invited to visit schools and work with students. My second folio piece investigates author visits in five secondary schools, from the perspectives of English teachers, teacher librarians and cohorts of middle school students. I wanted to find out why schools ask authors to visit and what are the expected outcomes of these visits, particularly in regard to adolescent reading identities. The third folio piece examines authors’ narratives concerning school visits. Authors have certain expectations when working with students and talking about their writing. I wanted to discover how authors think they can provide maximum impact on students through their visits, by asking a cohort of authors to recount their ‘dream school’ visits and ‘nightmare school’ visits. Interpretations of the research about boys and reading, and author visits from the schools’ perspectives are analysed using a form of content analysis. The third research project concerning authors’ narratives is interpreted using lexical networks. Prominent elements of my study explore adolescent reader identities through the influences of schooling and through author visits. In the conclusion of this study, these elements are drawn together and broad recommendations are outlined that pertain to the encouragement of positive adolescent reading identities.

Working around a contested diagnosis : borderline personality disorder in adolescence

This discourse analytic study sits at the intersection of everyday communications with young people in mental health settings and the enduring sociological critique of diagnoses in psychiatry. The diagnosis of borderline personality disorder (BPD) is both contested and stigmatized, in mental health and general health settings. Its legitimacy is further contested within the specialist adolescent mental health setting. In this setting, clinicians face a quandary regarding the application of adult diagnostic criteria to an adolescent population, aged less than 18 years. This article presents an analysis of interviews undertaken with Child and Adolescent Mental Health Services (CAMHS) clinicians in two publicly funded Australian services, about their use of the BPD diagnosis. In contrast with notions of primacy of diagnosis or of transparency in communications, doctors, nurses and allied health clinicians resisted and subverted a diagnosis of BPD in their work with adolescents. We delineate specific social and discursive strategies that clinicians displayed and reflected on, including: team rules which discouraged diagnostic disclosure; the lexical strategy of hedging when using the diagnosis; the prohibition and utility of informal ‘borderline talk’ among clinicians; and reframing the diagnosis with young people. For clinicians, these strategies legitimated their scepticism and enabled them to work with diagnostic uncertainty, in a population identified as vulnerable. For adolescent identities, these strategies served to forestall a BPD trajectory, allowing room for troubled adolescents to move and grow. These findings illuminate how the contest surrounding this diagnosis in principle is expressed in everyday clinical practice.

An examination of the associations among multiple memory systems, past tense, and vocabulary in typically developing 5 year old children

Purpose: Considerable research has investigated the role of verbal working memory in language development in children with and without language problems. Much less is currently known about the relationship between language and the declarative and procedural memory systems. This study examined whether these 2 memory systems were related to typically developing children's past tense and lexical knowledge.

Method: Fifty-eight typically developing children approximately 5 years of age completed a battery of linguistic and nonlinguistic tasks, including tests of vocabulary, past tense production, and procedural and declarative memory.

Results: The results showed that declarative and procedural memory were not correlated with either regular or irregular past tense use. A significant correlation was observed between declarative memory and vocabulary.

Conclusions: The results of the study were not consistent with the view that the declarative and procedural memory systems support children's use of the regular and irregular past tense. However, evidence was found suggesting that declarative memory supports vocabulary in this age group.

Comparable effects of nicotine in smokers and nonsmokers on a prospective memory task

In a double-blind placebo-controlled study, we examined the effect of nicotine, a cholinergic agonist, on performance of a prospective memory (ProM) task in young adult volunteers.

Volunteers were required to complete an ongoing lexical decision task while maintaining the ProM task (responding with a different button press to items containing particular target letters). Half of the volunteers were smokers, half were nonsmokers. Half of each group received a single dose (1 mg) of nicotine nasal spray before completing the task; the remaining volunteers received a matched inactive placebo spray.

Nicotine improved performance on the ProM task when volunteers were able to devote resources to that task. Under a variant procedure, where volunteers completed a concurrent auditory monitoring task, ProM performance was impaired under nicotine. Results are discussed in terms of the resource model of ProM, and the arousal model of drug effects.

Nicotine improves memory for delayed intentions

Rationale
The present paper asked first whether the cholinergic agonist nicotine improves memory for delayed intentions (prospective memory, ProM) and second whether pharmacological dissociation would support the psychological distinction that is made between strategic (effortful) and automatic (non-effortful) intention activation in prospective memory.
