The Impact

Objectives This study investigates the hypothesis that hearing aid amplification reduces effort within conversation for both hearing aid wearers and their communication partners. Levels of effort, in the form of speech production modifications, required to maintain successful spoken communication in a range of acoustic environments are compared to earlier reported results measured in unaided conversation conditions. Design Fifteen young adult normal-hearing participants and 15 older adult hearing-impaired participants were tested in pairs. Each pair consisted of one young normal-hearing participant and one older hearing-impaired participant. Hearing-impaired participants received directional hearing aid amplification, according to their audiogram, via a master hearing aid with gain provided according to the NAL-NL2 fitting formula. Pairs of participants were required to take part in naturalistic conversations through the use of a referential communication task. Each pair took part in five conversations, each of 5-min duration. During each conversation, participants were exposed to one of five different realistic acoustic environments presented through highly open headphones. The ordering of acoustic environments across experimental blocks was pseudorandomized. Resulting recordings of conversational speech were analyzed to determine the magnitude of speech modifications, in terms of vocal level and spectrum, produced by normal-hearing talkers as a function of both acoustic environment and the degree of high-frequency average hearing impairment of their conversation partner. Results The magnitude of spectral modifications of speech produced by normal-hearing talkers during conversations with aided hearing-impaired interlocutors was smaller than the speech modifications observed during conversations between the same pairs of participants in the absence of hearing aid amplification. Conclusions The provision of hearing aid amplification reduces the effort required to maintain communication in adverse conditions. This reduction in effort provides benefit to hearing-impaired individuals and also to the conversation partners of hearing-impaired individuals. By considering the impact of amplification on both sides of dyadic conversations, this approach contributes to an increased understanding of the likely impact of hearing impairment on everyday communication.

Referential Expressions

Purpose Speakers adjust referential expressions to the listeners' knowledge while communicating, a phenomenon called “audience design.” While individuals with Alzheimer's disease (AD) show difficulties in discourse production, it is unclear whether they exhibit preserved partner-specific audience design. The current study examined if individuals with AD demonstrate partner-specific audience design skills. Method Ten adults with mild-to-moderate AD and 12 healthy older adults performed a referential communication task with two experimenters (E1 and E2). At first, E1 and participants completed an image-sorting task, allowing them to establish shared labels. Then, during testing, both experimenters were present in the room, and participants described images to either E1 or E2 (randomly alternating). Analyses focused on the number of words participants used to describe each image and whether they reused shared labels. Results During testing, participants in both groups produced shorter descriptions when describing familiar images versus new images, demonstrating their ability to learn novel knowledge. When they described familiar images, healthy older adults modified their expressions depending on the current partner's knowledge, producing shorter expressions and more established labels for the knowledgeable partner (E1) versus the naïve partner (E2), but individuals with AD were less likely to do so. Conclusions The current study revealed that both individuals with AD and the control participants were able to acquire novel knowledge, but individuals with AD tended not to flexibly adjust expressions depending on the partner's knowledge state. Conversational inefficiency and difficulties observed in AD may, in part, stem from disrupted audience design skills.

Conversational Competence

ABSTRACTThis study examined learning disabled children's understanding of conversational rules for initiating the repair of a communicative breakdown. Learning disabled and normal children in grades 1 through 8 played the listener role in a referential communication task requiring them to select referents based on messages varying in informational adequacy. Learning disabled children were less likely to request clarification of inadequate messages and, consequently, made fewer correct referent choices than normal children. Only young learning disabled girls were less able than their normal age-mates to appraise message adequacy. Analyses of response latencies and request type also suggest that the failure to request clarification cannot be attributed solely to linguistic deficits. Results are discussed in terms of the relative contributions of syntactic-semantic ability and social knowledge to conversational competence.

ABSTRACTThree- and four-year-olds participated in a referential communication task wherein they requested stickers from a knowledgeable or ignorant adult to complete a card. Following inadequate initial requests children were provided with three different feedback types: goal substitution (i.e. an incorrect sticker was provided), explicit statement of misunderstanding (‘I don't know which one you mean’), and vague feedback (‘Huh?’). Preschoolers' initial statements revealed sensitivity to the listener's perspective: more descriptors were provided when the listener did not have visual access to the card. Although listener's knowledge did not affect children's repair statements following feedback, the feedback type did: goal substitution elicited more repairs that included new descriptors, whereas vague responses elicited more repetition of initial requests than other feedback types. Children's age and verbal skills were related to the specific repair strategies used. Results demonstrate that preschoolers' use of cues from a conversational partner depends on the type of communicative task.

Specific Contribution

This work aims to analyse the specific contribution of social abilities (here considered as the capacity for attributing knowledge to others) in a particular communicative context. 74 normally developing children (aged 3;4 to 5;9, M=4·6) were given two Theory of Mind (ToM) tasks, which are considered to assess increasing complexity levels of epistemic state attribution: Attribution of knowledge-ignorance (Pillow, 1989; adapted by Welch-Ross, 1997) and Understanding of False-belief (Baron Cohen, Leslie & Frith, 1985). Subjects were paired according to their age and level of performance in ToM tasks. These dyads participated in a referential communication task specially designed for this research. The resulting communicative interchanges were analysed using a three-level category system (pragmatic functions, descriptive accuracy, and ambiguity of messages). The results showed significant differences among subjects with different levels of social comprehension regarding the type of communicative resources used by them in every category level. In particular, understanding of false belief seems to be the most powerful predictor of changes in the children’s development of communicative competence.

Target Attributes

ABSTRACTWe examined the effects of object attributes on children's descriptive patterns in a referential communication task. Thirty preschoolers described object pairs that were selected by the experimenter. The targets were defined by shared size or colour, and differed on the non-target dimension in half of the trials. The children also completed a non-verbal reasoning task with analogous stimuli. They selected objects after observing the experimenter make a choice and inferring the basis for selection. In the communication task, the children produced fewer size than colour descriptions, particularly when the size targets differed in colour. They also over-specified colour features more often than size. They did not show a similar challenge identifying size relationships in the non-verbal task. The results support the conclusion that target attributes have a systematic influence on children's referential performance. Potential mechanisms for these effects, and directions for future research are discussed.
