An examination of perceptions of parental influence on attitudes to language learning

from Educational Research

Background The assumption that parents have some effect on their children’s attitudes to learning is one that few educationalists would challenge. The ways in which this influence is brought to bear are a slightly more complex and contentious matter, however.

Purpose The paper uses data from a tri-national PhD study on pupil attitudes to examine perceptions of the ways in which parents influence children’s orientations towards foreign language learning (FLL). The comparative element is useful in providing a contrasting range of settings in which to examine the issue. The paper thus aims to provide some indication of the similarity and importance of particular influences by identifying features that seem significant, irrespective of setting.

Sample A total of 411 learners of French, German and English (as foreign languages), represented in roughly equal numbers from across the ability range, took part in the survey. The pupils, aged 15 – 16, were drawn from two centrally located mixed comprehensive schools in each country—England, Germany and The Netherlands. The schools were similar in terms of size, social intake and their semi-urban location. Care was taken to ensure as close a gender balance as possible.

Design and methods The study was designed as a qualitative survey and involved three data collection instruments. The first stage of data was collected using a written word association prompt distributed to the whole sample. The second stage involved around half the pupils generating written accounts of their attitudes and the factors they perceived to be influential. A total of 80 pupils took part in the final stage, consisting of 14 focus group interviews. A system of open coding was applied to all the data to support the process of inductive category building used in their analysis.

Results The findings offer some evidence for an association between parental and pupil attitudes. Parental influence appears to operate in a number of ways, ranging from the role model potential of positive/negative behaviours and the communication of educational regrets, to the ways in which parents help to construct their children’s understandings of language importance and status. The extent of parental language knowledge appears to be an important additional factor.

Conclusions The evidence suggests that the ways in which parents contribute to the construction of their children’s understanding of language utility are particularly important, and that this may be a key factor in the more positive attitudes demonstrated by the German pupils and the more negative orientations among the English participants.

Storytelling as a democratic approach to data collection: interviewing children about reading

from Educational Research

Background Before the 1990s, an individual or medical model dominated educational research methodology with respect to younger children: the subjects of the research were usually considered untrustworthy sources of information. A subsequent shift towards an ecological model has focused on the child’s perspective: however, Lewis and Lindsay have described the development of methods for conducting research with children as slow.

Purpose This paper examines how storytelling can be used as a method of collecting authentic and revealing research data from children. The method is suggested as a valuable way in which to gain insights into children’s discourse, and is used in this paper in relation to children’s discourse about reading.

Sample, design and methods The storytelling method was initially trialled in one school with 36 children aged between 5 and 11 years. The storytelling interview was then used in case studies over a period of a year in three schools, with a total of 88 7- and 8-year-old children. During the interviews, children were asked to tell a story entitled ‘The child who didn’t like reading’. Systematic content analysis was undertaken to identify emergent cultural norms and models in the stories. Information on the children’s reading practices, and their observations on reading, was also collected for the purposes of triangulation.

Results The children’s storytelling gave access to their cultural models of reading. It was found that the stories demonstrated sufficient triangulation with the other data about the children’s reading practices to support a sociocultural production of the children’s discourse.

Conclusions Storytelling can provide a useful and credible method of collecting research data from children. It may be especially useful with poor readers as there are no literacy demands, and in this respect, affords socially inclusive research.

Attention orienting effects of hesitations in speech: Evidence from ERPs

from the Journal of Experimental Psychology: Learning, Memory, and Cognition

Filled-pause disfluencies such as um and er affect listeners’ comprehension, possibly mediated by attentional mechanisms (J. E. Fox Tree, 2001). However, there is little direct evidence that hesitations affect attention. The current study used an acoustic manipulation of continuous speech to induce event-related potential components associated with attention (mismatch negativity [MMN] and P300) during the comprehension of fluent and disfluent utterances. In fluent cases, infrequently occurring acoustically manipulated target words gave rise to typical MMN and P300 components when compared to nonmanipulated controls. In disfluent cases, where targets were preceded by natural sounding hesitations culminating in the filled pause er, an MMN (reflecting a detection of deviance) was still apparent for manipulated words, but there was little evidence of a subsequent P300. This suggests that attention was not reoriented to deviant words in disfluent cases. A subsequent recognition test showed that nonmanipulated words were more likely to be remembered if they had been preceded by a hesitation. Taken together, these results strongly implicate attention in an account of disfluency processing: Hesitations orient listeners’ attention, with consequences for the immediate processing and later representation of an utterance.

Feedback consistency effects in visual and auditory word recognition: Where do we stand after more than a decade?

from the Journal of Experimental Psychology: Learning, Memory, and Cognition

The role of phonology-to-spelling consistency (i.e., feedback consistency) was investigated in 3 lexical decision experiments in both the visual and auditory modalities in French and English. No evidence for a feedback consistency effect was found in the visual modality, either in English or in French, despite the fact that consistency was manipulated for different kinds of units (onsets and rimes). In contrast, robust feedback consistency effects were obtained in the auditory lexical decision task in both English and French when exactly the same items that produced a null effect in the visual modality were used. Neural network simulations are presented to show that previous demonstrations of feedback consistency effects in the visual modality can be simulated with a model that is not sensitive to feedback consistency, suggesting that these effects might have come from various confounds. These simulations, together with the authors’ results, suggest that there are no feedback consistency effects in the visual modality. In contrast, such effects are clearly present in the auditory modality. Given that orthographic information is absent from current models of spoken word recognition, the present findings present a major challenge to these models.

Revisiting evidence for modularity and functional equivalence across verbal and spatial domains in memory

from the Journal of Experimental Psychology: Learning, Memory, and Cognition

The authors revisited evidence in favor of modularity and of functional equivalence between the processing of verbal and spatial information in short-term memory. This was done by investigating the patterns of intrusions, omissions, transpositions, and fill-ins in verbal and spatial serial recall and order reconstruction tasks under control, articulatory suppression, and spatial tapping conditions. The authors observed that when tasks were fully equated, all patterns of errors were equivalent between the verbal and spatial domains. Moreover, articulatory suppression interfered more with the verbal memory tasks than with the spatial memory tasks. This interference was mostly due to an increase of omissions and transpositions. Similarly, tapping was more disruptive of spatial memory than of verbal memory tasks and affected primarily the number of omissions and transpositions. The patterns of errors and their interaction with interference are discussed in light of the predominant approaches to modeling memory and provide a rich set of data for modeling efforts.

Association between therapy outcome and right-hemispheric activation in chronic aphasia

from Brain

The role of the right hemisphere for language processing and successful therapeutic interventions in aphasic patients is a matter of debate. This study explored brain activation in right-hemispheric areas and left-hemispheric perilesional areas in response to language tasks in chronic non-fluent aphasic patients before and after constraint-induced aphasia therapy (CIAT). In particular, we analysed the relation between brain responses and therapy outcome. Using functional magnetic resonance imaging (fMRI), brain activation was measured during word-reading (REA) and word-stem completion (COM) in 16 chronic non-fluent aphasic and 8 healthy subjects. Before therapy, activation in right inferior frontal gyrus/insula (IFG/IC) was stronger in aphasics compared to controls during REA and in precentral gyrus (PCG) during COM. Therapeutic intervention per se did not change brain activation for either task across all aphasic subjects. However, therapeutic success correlated with a relative decrease of activation in right-hemispheric areas, including the IFG/IC. Most importantly, initial activation in right IFG/IC and other right-hemispheric areas correlated positively with subsequent therapy success. Thus, right-hemispheric activation prior to aphasia therapy strongly predicts therapeutic success, suggesting that brain activation in chronic aphasia indicates the patients’ potential for further language improvement.

Newborn Hearing Screening and Detection of Congenital Cytomegalovirus Infection

from Pediatrics

OBJECTIVES. The objectives were to determine the frequency of congenital cytomegalovirus infection among newborns who did not pass hearing screening tests or had confirmed hearing loss and to determine how often abnormal hearing screening results were the only manifestation of congenital cytomegalovirus infection.

METHODS. Retrospective chart review was performed for newborns who had abnormal hearing screening results and positive urine cytomegalovirus culture results at Parkland Memorial Hospital between September 1, 1999, and August 31, 2004.

RESULTS. During the 5-year study period, 572 of 79047 newborns (7 of 1000 live births) did not pass hearing screening tests. Cytomegalovirus infection was identified in 24 (5%) of 483 tested infants and 16 (6%) of the 256 infants with subsequently confirmed hearing impairment. Of those 16 infants, 12 (75%) were identified as having congenital cytomegalovirus infection only because of failure to pass newborn hearing screening tests.

CONCLUSIONS. Congenital cytomegalovirus infection was present for 6% of newborns with confirmed hearing impairment, and the majority of those infants were identified on the basis of abnormal newborn hearing screening results.

Prenatal and Postnatal Growth and Cognitive Abilities at 56 Months of Age: A Longitudinal Study of Infants Born at Term

from Pediatrics

OBJECTIVE. The aim of the study was to investigate whether weight, length, BMI (kilograms per meter squared), and head circumference at birth and their postnatal growth are associated with cognitive abilities at 56 months of age among infants born at term.

PATIENTS AND METHODS. Our sample was composed of 1056 Finnish children born at term, (37 to 41 weeks) free of any major impairments. Weight, length, and head circumference were measured at birth and at 5, 20, and 56 months of age, and BMI was calculated. We assessed cognitive abilities by conducting tests of general reasoning, visual-motor integration, verbal competence, and language comprehension at 56 months of age.

RESULTS. Firstly, for every 1 SD lower in weight or BMI at birth, general reasoning and/or visual-motor integration was >1.20 points lower, and for every 1 SD lower in length or head circumference at birth, abilities across all of the cognitive domains were >1.31 points lower. Second, for every 1 SD slower gain in weight or BMI from birth to 5 months, general reasoning and visual-motor integration decreased by >0.97 points; for every 1 SD slower gain in length from 5 to 20 months and from 20 to 56 months, respectively, visual-motor integration, and verbal competence and language comprehension decreased by >1.03 points; and for every 1 SD slower increase in head circumference from birth to 5 months and from 5 to 20 months, respectively, visual-motor integration and language comprehension decreased by >1.17 points. Third, tests for nonlinear relationships revealed that, in some cases, large body size and faster growth were also associated with lower scores in cognitive tests.

CONCLUSIONS. Our findings suggest that, even within the range of children born at term, prenatal and postnatal growth in body size are associated with individual differences in cognitive abilities.

Unbound Bilirubin Concentration is Associated With Abnormal Automated Auditory Brainstem Response for Jaundiced Newborns

from Pediatrics

OBJECTIVE. This study was conducted to determine whether incidental jaundice affects automated auditory brainstem response results.

METHODS. We reviewed the medical charts of jaundiced newborns of 34 weeks of gestation who underwent automated auditory brainstem response testing within 4 hours of plasma total bilirubin concentration and unbound bilirubin concentration measurements. We tested the hypothesis that the likelihood of abnormal automated auditory brainstem response results would increase as total bilirubin and unbound bilirubin concentrations increased.

RESULTS. Forty-four infants with proximate total bilirubin concentration, unbound bilirubin concentration, and automated auditory brainstem response measurements were identified, and 4 (9%) had bilateral refer automated auditory brainstem response results. The mean total bilirubin concentration of 21.4 mg/dL (SD: 4.0 mg/dL; range: 14.4–29.5 mg/dL) for the 40 infants with bilateral pass automated auditory brainstem response results was not significantly different from that of 23.0 mg/dL (range: 14.9–33.1 mg/dL) for the 4 infants with bilateral refer automated auditory brainstem response results. However, the mean unbound bilirubin concentration of 1.32 µg/dL (range: 0.22–2.99 µg/dL) for the 40 infants with bilateral pass results was significantly lower than the mean of 2.62 µg/dL (range: 0.88–4.41 µg/dL) for the 4 infants with bilateral refer results. Logistic regression showed that increasing unbound bilirubin concentrations but not increasing total bilirubin concentrations were associated with of bilateral refer automated auditory brainstem response results.

CONCLUSIONS. The probability of bilateral refer automated auditory brainstem response results increases significantly with increasing unbound bilirubin concentrations but not with increasing total bilirubin concentrations. Because unbound bilirubin concentrations are also more closely correlated with bilirubin neurotoxicity than are total bilirubin concentrations, bilateral refer automated auditory brainstem response results for jaundiced newborns may indicate increased risk of bilirubin neurotoxicity, in addition to the possibility of congenital deafness.

New research on hearing health underscores the importance of better hearing and speech month

from EurekAlert.org

Three studies published in the May 2008 edition of Otolaryngology – Head and Neck Surgery reveal substantial new findings in several areas of hearing health, including research that indicates that patients with profound hearing loss benefit substantially from having cochlear implants placed in both ears, rather than one, as is the common practice.

The efficacy of speech intervention using electropalatography with an 18-year-old deaf client: A single case study

from the International Journal of Speech-Language Pathology

This single case study explored the use of EPG as a therapeutic tool for treating inaccurate articulation of the voiceless alveolar plosive /t/. The participant (M) is an 18-year-old deaf1 adult who consistently uses hearing aids, and who communicates using a combination of English, Sign Supported English and British Sign Language (BSL). M received traditional phonological therapy targeting his production of /t/ prior to EPG therapy, but without success. He requested further therapy and EPG was offered as an alternative approach. Pre-EPG therapy, M made tongue placement errors for both /t/ and the voiced alveolar plosive /d/. Based on perceptual analysis by M’s speech and language therapist, the first author, his productions were inconsistent, though generally perceived as voiceless and voiced velar plosives respectively. The EPG therapy consisted of six bi-weekly therapy sessions, each lasting for 1 hour, targeting M’s production of /t/ in familiar words, using the visual feedback from the EPG display. Trained and untrained listeners perceptually analysed audio recordings of words and sentences collected at three assessment points. Improvements, both over the course of the EPG therapy and during the follow-up period, were found to be statistically significant. Significantly, M was able to generalize his production skills to untaught words containing both /t/ and /d/. Equally significant was the lack of change in M’s production of a control sound, the voiceless dental fricative /θ/. More globally, an improvement was observed in ratings of M’s intelligibility in sentences and in his voice quality (assessed impressionistically).

Change of Acoustic Parameters Before and After Treatment in Laryngopharyngeal Reflux Patients

from Laryngoscope

Objectives: To evaluate the usefulness of acoustic parameters as an indicator of laryngopharyngeal reflux (LPR) treatment efficacy.

Study Design: A prospective case series analysis.

Materials and Methods: From January to September 2005, we prospectively analyzed 40 patients who were diagnosed with laryngopharyngeal reflux by 24-hour ambulatory double-probe pH monitoring. Laryngopharyngeal reflux patients were treated medically and voice analysis was conducted three times: before treatment, 1 to 2 months after treatment, and 3 to 4 months after treatment. Jitter, shimmer, and harmonic-to-noise ratio (HNR) were analyzed as the acoustic parameters. Pre- and posttreatment reflux symptom index and reflux finding score were documented.

Results: Jitter, shimmer, and HNR had improved significantly at 1 to 2 months after treatment and were maintained at 3 to 4 months after treatment. Jitter was significantly correlated with reflux symptom index.

Conclusion: Acoustic parameters can be used as indicators of treatment efficacy for laryngopharyngeal reflux disease.

Phonological working memory with auditory presentation of pseudo-words — An event related fMRI Study

from Brain Research

Phonological working memory (PWM) tasks consist of a sequence of stimulus-encoding, maintenance and response. Few previous functional magnetic resonance imaging (fMRI) studies of PWM have employed event-related designs that make it possible to analyze the activations associated with each phase of such a task. The exploration of the cortical activation that takes place during the maintenance of PWM has been of particular interest to us. It has been suggested that temporary storage is served by the inferior parietal cortex. However, to the best of our knowledge earlier studies have used visual stimuli that might generate different cortical activations than auditory stimuli, which, presumably, would be more dependent on the auditory association cortex in the temporal lobe. This study involved an auditory stimulus presentation and a forced two-choice task. We used a parametric event-related design with fMRI. The stimuli consisted of pseudo-words of five, seven and nine syllables in length. In the control task, acoustically analogous stimuli without phonetic or linguistic content were used for passive listening. The left inferior frontal gyrus was activated during the stimulus-encoding, maintenance and response, in agreement with previous studies. However, in contrast to previous studies using visual presentation of verbal material, the inferior parietal cortex was not activated during the maintenance in the present study, but only active in the comparison and decision phase. Significant activation of the auditory cortex in the middle temporal gyrus was observed during the maintenance phase, which, together with the inferior frontal gyrus activation might underly the maintenance of phonological information.
