Puzzle Task

Purpose The purpose of this study was to introduce a method of eliciting conversational behavior with many aspects of realism, which may be used to study the impacts of hearing impairment and noise on verbal communication; to describe the characteristics of speech and language participants produced during the task; and to assess participants' engagement and motivation while completing the task. Method Twenty young adults with normal hearing and 20 older adults with hearing impairment took part in face-to-face conversations while completing a referential communication puzzle task designed to elicit natural conversational speech production and language with a number of realistic characteristics. Participants rated the difficulty and relevance of acoustic scenes for communication and their engagement in conversations. Results The communication task elicited speech production in a natural conversational register and language with many realistic characteristics, including complex linguistic constructions and typical disfluencies found in everyday speech, and approximately balanced contributions within dyads. Subjective ratings suggest that the task is robust to learning and fatigue effects and that participants remained highly engaged throughout the experiment. All participants were able to maintain successful communication regardless of background noise level and degree of hearing impairment. Conclusions The communication task described here may be used as part of a functional assessment of the ability to communicate in the presence of noise and hearing impairment. Although existing speech assessments have many strengths, they do not take into account the inherently interactive nature of spoken communication or the effects of motivation and engagement.

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.

A foundational assumption of human communication is that speakers ought to say as much as necessary, but no more. How speakers determine what is necessary in a given context, however, is unclear. In studies of referential communication, this expectation is often formalized as the idea that speakers should construct reference by selecting the shortest, sufficiently informative, description. Here we propose that reference production is, instead, a process whereby speakers adopt listeners’ perspectives to facilitate their visual search, without concern for utterance length. We show that a computational model of our proposal predicts graded acceptability judgments with quantitative accuracy, systematically outperforming brevity models. Our model also explains crosslinguistic differences in speakers’ propensity to over-specify in different visual contexts. Our findings suggest that reference production is best understood as driven by a cooperative goal to help the listener understand the intended message, rather than by an egocentric effort to minimize utterance length.

Abstract There is relatively good evidence that non-human primates can communicate about objects and events in their environment in ways that allow recipients to draw inferences about the nature of the event experienced by the signaller. In some species, there is also evidence that the basic semantic units are not individual calls, but call sequences and the combinations generated by them. These two findings are relevant to theories pertaining to the origins of human language because of the resemblances of these phenomena with linguistic reference and syntactic organisation. Until recently, however, most research efforts on the primate origins of human language have involved Old World species with comparatively few systematic studies on New World monkeys, which has prevented insights into the deeper phylogenetic roots and evolutionary origins of language-relevant capacities. To address this, we review the older primate literature and very recent evidence for functionally referential communication and call combinations in New World primates. Within the existing literature there is ample evidence in both Callitrichids and Ce-bids for acoustically distinct call variants given to external disturbances that are accompanied by distinct behavioural responses. A general pattern is that one call type is typically produced in response to a wide range of general disturbances, often on the ground but also including inter-group encounters, while another call type is produced in response to a much narrower range of aerial threats. This pattern is already described for Old World monkeys and Prosimians, suggesting an early evolutionary origin. Second, recent work with black-fronted titi monkeys has produced evidence for different alarm call sequences consisting of acoustically distinct call types. These sequences appear to encode several aspects of the predation event simultaneously, notably predator type and location. Since meaningful call sequences have already been described in Old World primates, we suggest that basic combinatorial vocal communication has evolved in the primate lineage long before the advent of language. Moreover, it is possible that some of these communicative abilities have evolved even earlier, or independently, as there is comparable evidence in other taxonomic groups. We discuss these findings in an attempt to shed further light on the primate stock from which human language has arisen.

Caregivers exhibiting low levels of positive caregiving tend to have reduced dynamic range in high- frequency heart rate variability (HRV), an index of parasympathetic nervous system activity. Yet less is known about the involvement of the sympathetic nervous system, which may impact the plausible range of parasympathetic reactivity. Here, caregiver–child dyads completed resting assessments of HRV and pre-ejection period (PEP), followed by a videotaped puzzle task during which HRV was measured and observers coded the degree of caregivers’ positive emotionality. Multilevel modelling was employed to characterize task fluctuations in HRV as a function of resting PEP and caregivers’ positive emotional expressions. Higher frequency of caregiver positivity was associated with greater HRV reactivity in caregivers but not children. Increased caregiver positivity was correlated with longer resting PEP in children. These results replicate findings of greater caregiver parasympathetic flexibility during positive caregiving and extend those findings to children’s resting sympathetic activity.

General Communication

Disorders of spoken language have long been associated with learning disabilities. Recent research has focused less on linguistic characteristics and more on general communication effectiveness. This study investigated the referential communication ability of LD and non-LD elementary students. Developmental research has indicated that this language function tends to be well developed by early childhood and is a major precursor of later communication competence. Results of the present study indicated that LD students were less effective in providing descriptive information about objects than non-LD peers. Further analysis of LD communication revealed that such a lack of effectiveness was due to the LD students' limited use of labeling in their verbal descriptions.
