Purpose People with aphasia (PWA) use different kinds of gesture spontaneously when they communicate. Although there is evidence that the nature of the communicative task influences the linguistic performance of PWA, so far little is known about the influence of the communicative task on the production of gestures by PWA. We aimed to investigate the influence of varying communicative constraints on the production of gesture and spoken expression by PWA in comparison to persons without language impairment. Method Twenty-six PWA with varying aphasia severities and 26 control participants (CP) without language impairment participated in the study. Spoken expression and gesture production were investigated in 2 different tasks: (a) spontaneous conversation about topics of daily living and (b) a cartoon narration task, that is, retellings of short cartoon clips. The frequencies of words and gestures as well as of different gesture types produced by the participants were analyzed and tested for potential effects of group and task. Results Main results for task effects revealed that PWA and CP used more iconic gestures and pantomimes in the cartoon narration task than in spontaneous conversation. Metaphoric gestures, deictic gestures, number gestures, and emblems were more frequently used in spontaneous conversation than in cartoon narrations by both participant groups. Group effects show that, in both tasks, PWA's gesture-to-word ratios were higher than those for the CP. Furthermore, PWA produced more interactive gestures than the CP in both tasks, as well as more number gestures and pantomimes in spontaneous conversation. Conclusions The current results suggest that PWA use gestures to compensate for their verbal limitations under varying communicative constraints. The properties of the communicative task influence the use of different gesture types in people with and without aphasia. Thus, the influence of communicative constraints needs to be considered when assessing PWA's multimodal communicative abilities.

Normal Status

This study is a posthumous longitudinal study of consecutive letters written by an elderly woman from age 89 to 93. Findings reveal a consistent linguistic performance during the first 3 years, supporting “normal” status for late elderly writing. She produced clearly written cursive form, intact semantic content, and minimal spelling and stroke errors. A decline in writing was observed in the last 6–9 months of the study and an analysis revealed production of clausal fragmentation, decreasing semantic clarity, and a higher frequency of spelling, semantic, and stroke errors. Analysis of writing samples can be a valuable tool in documenting a change in cognitive status differentiated from normal late aging.

AbstractPeople learn language from their social environment. Therefore, individual differences in the input that their social environment provides could influence their linguistic performance. Nevertheless, investigation of the role of individual differences in input on performance has been mostly restricted to first and second language acquisition. In this paper I argue that individual differences in input can influence linguistic performance even in adult native speakers. Specifically, differences in input can affect performance by influencing people’s knowledgebase, by modulating their processing manner, and by shaping expectations. Therefore, studying the role that individual differences in input play can improve our understanding of how language is learned, processed and represented.

Organizational View

Most everyone agrees that context is critical to the pragmatic interpretation of speakers’ utterances. But the enduring debate within cognitive science concerns when context has its influence in shaping people’s interpretations of what speakers imply by what they say. Some scholars maintain that context is only referred to after some initial linguistic analysis of an utterance has been performed, with other scholars arguing that context is present at all stages of immediate linguistic processing. Empirical research on this debate is, in my view, hopelessly deadlocked. My goal in this article is to advance a framework for thinking about the context for linguistic performance that conceives of human cognition and language use in terms of dynamical, self-organized processes. A self-organizational view of the context for linguistic performance demands that we acknowledge the multiple, interacting constraints which create, or soft-assemble, any specific moment of pragmatic experience. Pragmatic action and understanding is not producing or recovering a “meaning” but a continuously unfolding temporal process of the person adapting and orienting to the world. I discuss the implications of this view for the study of pragmatic meaning in discourse.
