ObjectivesThis document presents the fundamentals of speech audiometry in noise, general requirements for implementation and criteria for choice among the tests available in French according to the health-professional's needs.Material and methodsThe recommendations are based on a systematic analysis of the literature carried out by a multidisciplinary group of doctors, audiologists and audioprosthetists from all over France. They are graded A, B, C or expert opinion according to decreasing level of scientific evidence.ResultsEight tests of speech audiometry in noise can be used in France.ConclusionTo be complete, evaluation of hearing status requires testing understanding of speech in noise. The examination must begin with a minimum of two measurements familiarizing the subject with the test procedure. For initial diagnosis, adaptive procedures establishing the 50% speech reception threshold (SRT50) in noise are to be preferred in order to obtain a rapid and standardized measurement of perception of speech in noise. When the aim is to measure real-life speech comprehension, tests based on sentences, cocktail-party noise and free-field stimulation are to be preferred. Prosthetic gain is evaluated exclusively in free field. This is the only way to evaluate the contribution of binaurality and to measure perception in noise in an environment as close as possible to real life. In order to avoid acoustic interference in free field, at least five loudspeakers should be used, in particular for evaluating the effectiveness of directional microphones, CROS devices enabling sounds picked up in the damaged ear to be rerouted to the functional ear, or bimodal fitting (i.e., when hearing is enabled by two modalities: for example, hearing aid for one ear, cochlear implant for the other). 相似文献
The European Clinical Trial Regulation No 536/2014 is the first mandate for a non-technical, publicly disclosed, plain language summary (PLS) of clinical trial results. This easy-to-understand summary has the potential to inform the public about clinical trial results and thereby improve health literacy in vaccines.To investigate the utility of the PLS, we undertook 2 online surveys (July/October 2020) in the United Kingdom, the United States and India. Participants were selected by quota sampling to ensure representation of gender, age and parental status. Those lacking interest in vaccine clinical research were excluded. In survey 1, participants were questioned about their interest in and expectations of vaccine trial results. In survey 2, the perceptions of participants to a range of written communication styles used in publicly available PLSs were evaluated.A total of 66 (13%) and 122 (29%) individuals were excluded solely due to lack of interest in vaccine clinical research in surveys 1 and 2, respectively; 450 respondents (150/country) completed survey 1 and 300 (100/country) completed survey 2. In survey 1, there was a correlation (p < 0.01) between claimed knowledge of and trust in vaccines. Healthcare professionals were the most trusted source for vaccine information, while vaccine companies were ranked relatively low. In survey 2, infographic PLS formats were considered easiest to understand, most engaging and the strongest communicators. Emphasizing the main points of the infographics in the text did not improve comprehension or recall. Most respondents (86%) indicated that they would like to see this type of communication in the future.Overall, this research suggests that the PLS, by optimizing content and format, has a potential to increase health literacy, and thereby, as part of a wider integrated communication strategy, build vaccine knowledge and confidence. 相似文献
Introduction: Semantic priming paradigms are important for understanding lexical–semantic processing and the nature of linguistic deficits accompanying language performance in neurologically impaired individuals such as people with aphasia. Reaction-time-(RT)-based traditional semantic priming tasks entail potential confounds, especially problematic when applied to people with aphasia, who may have concomitant neurocognitive challenges that limit task performance. Some of these confounds include requirements of following complex instructions, making metalinguistic judgments, and using speech or limb-based motor actions to indicate overt responses. Eyetracking methods have great potential for avoiding some of these confounds. We tested the validity of an eyetracking method in capturing semantic priming in an auditory–visual cross-format priming paradigm (auditory word prime–visual image target).
Method: A total of 72 neurologically unimpaired adults participated in two phases: a stimulus development phase using traditional priming (n = 32) and an experimental eyetracking phase (n = 40). Each phase included two conditions, representing distinct levels of prime–target semantic relatedness: unrelated and related. Mean RT data from the traditional priming (stimuli development) phase guided image selection for the eyetracking experiment. Eyetracking indices of fixation duration and latency of fixation were recorded to capture semantic priming in the eyetracking experiment.
Results: Eye fixation data indicated that images related to auditory primes were attended to earlier and attracted significantly greater visual attention than unrelated images. These results mirrored RT data from the traditional priming method, which showed faster RT latencies and more accurate naming performance for related images than for unrelated images.
Conclusions: Results support the validity of eyetracking indices of semantic priming and offer a robust testing protocol for future studies in this line of research. Current clinical relevance for people with aphasia is highlighted. Further empirical testing of the psychometric properties of the eyetracking measures in various semantic priming contexts is recommended. 相似文献
The ability to speak is a unique human capacity, but where is it located in our brains? This question is closely connected to the pioneering work of Pierre Paul Broca in the 1860s. Based on post-mortem observations of aphasic patients' brains, Broca located language production in the 3rd convolution of the left frontal lobe and thus reinitiated the localizationist view of brain functions. However, contemporary neuroscience has partially rejected this view in favor of a network-based perspective. This leads to the question, whether Broca's findings are still relevant today. In this mini-review, we discuss current and historical implications of Broca's work by focusing on his original contribution and contrasting it with contemporary knowledge. Borrowing from Broca's famous quote, our review shows that humans indeed “speak with the left hemisphere”– but Broca's area is not the sole “seat of articulatory language”. 相似文献
Purpose: Numerous studies have reported a robust relationship between early phonological awareness (PA) and subsequent reading achievement, in addition to the critical role of the alphabetic principle in predicting and supporting later reading and spelling development. Given this association, there has been an increasing push to teach these skills to young children prior to word level reading and spelling instruction. This study evaluated the effectiveness of the Cracking the Code (CtC) program with students aged 3;8–5;4. CtC is a teacher-implemented program, designed to explicitly target PA skills and alphabet knowledge.
Method: A pre-test post-test group design was used to evaluate the effectiveness of the program. Four schools in metropolitan Western Australia were randomly assigned to either the control or experimental condition within a parallel groups design. The control group participated in an alternative program matched for duration and frequency, targeting semantics and grammar.
Result: The children in the experimental condition improved significantly more in PA, alphabet knowledge and non-word reading, and spelling after intervention than the control group.
Conclusion: These findings demonstrate that classroom-based, teacher-delivered PA and alphabet knowledge instruction can be effective for 3;8–5;4 year-olds. 相似文献
