How to refer to ‘diabetes’? Language in online health advice

The adaptation of vocabulary between communication partners, i.e. the lexical entrainment phenomenon, is well documented. This study investigates whether the phenomenon can also be found in computer‐mediated communication between experts and laypersons. The respondents, who are medical experts (n = 46), answered to fictitious patients' queries on health problems. Language technicality within patients' queries was manipulated. One version contained certain concepts in everyday language, the other in technical language. Do experts adapt the vocabulary in their replies to that in the inquiry? Detailed analyses provide evidence that experts not only use the inquiry vocabulary, but also adapt the content of their answers to the technicality of the inquiry. Surprisingly, though queries differ in the use of vocabulary experts attributed very similar prior knowledge to the fictitious patient while providing them with very different replies. The results are discussed with respect to the implications for health counselling and for theoretical assumptions about adaptation in net‐based discourse.

Virtual Learning in a Socially Digitized World

Contemporary education is awakening from a crisis that has held the development of its potential and its relevance at bay for well over a century. Revolutions in science and spirituality are emerging a new relational intelligence that demands commensurate educational paradigms for its blossoming into daily engagements with life and the world around us. At the same time as people are leading increasingly interconnected lives, aware of and often participating in the narratives of people and ecosystems in other parts of the planet, information and communications technologies are increasingly integrating with and serving to mediate the human experience. This article explores the power of this confluence at the current nexus of civilizational demands in the context of increased planetary stresses and destabilizations. The case is made for a thrivable education praxis that draws on these emergent aspects of our developmental potential and emphasizes the importance of functional conviviality as an operational principle of learning for life.     

Stuttering treatment control using P300 event-related potentials

Positron emission tomography studies during speech have indicated a failure to show the normal activation of auditory cortical areas in stuttering individuals. In the present study, P300 event-related potentials were used to investigate possible effects of behavioral treatment on the pattern of signal amplitude and latency between waves. In order to compare variations in P300 measurements, a control group paired by age and gender to the group of stutterers, was included in the study. Findings suggest that the group of stutterers presented a significant decrease in stuttering severity after the fluency treatment program. Regarding P300 measurements, stutterers and their controls presented results within normal limits in all testing situations and no significant statistical variations between pre and post treatment testing. When comparing individual results between the testing situations, stutterers presented a higher average decrease in wave latency for the right ear following treatment. The results are discussed in light of previous P300 event-related potentials and functional imaging studies with stuttering adults.Educational objectives: The reader will learn about and be able to describe the: (1) use of P300 event-related potentials in the study of stuttering; (2) differences between stuttering and non-stuttering adults; and (3) effects of behavioral fluency treatment on cerebral activity in stuttering speakers.     

Approximate entropy used to assess sitting postural sway of infants with developmental delay

Infant sitting postural sway provides a window into motor development at an early age. The approximate entropy, a measure of randomness, in the postural sway was used to assess developmental delay, as occurs in cerebral palsy. Parameters used for the calculation of approximate entropy were investigated, and approximate entropy of postural sway in early sitting was found to be lower for infants with developmental delay in the anterior-posterior axis, but not in the medial-lateral axis. Spectral analysis showed higher frequency features in the postural sway of early sitting of infants with typical development, suggesting a faster control mechanism is active in infants with typical development as compared to infants with delayed development, perhaps activated by near-fall events.     

Unpacking the Blockers: Understanding Perceptions and Social Constraints of Health Communication in Hereditary Breast Ovarian Cancer (HBOC) Susceptibility Families

Family communication is essential for accurate cancer risk assessment and counseling; family blockers play a role in this communication process. This qualitative analysis of social exchanges is an extension of earlier work characterizing those who are perceived by study participants as health information gatherers, disseminators, and blockers within families with Hereditary Breast and Ovarian Cancer (HBOC) susceptibility. Eighty-nine women, ages 23–56 years, enrolled in a Breast Imaging Study (BIS) and participated in a sub-study utilizing a social assessment tool known as the Colored Ecological Genetic Relational Map (CEGRM). Purposive sampling ensured that participants varied according to numbers of participating family members e.g., ranging from 1 to 6. Eighty-nine women from 42 families (1–8 relatives/family) participated. They collectively designated 65 blockers, both male and female. Situational factors, beliefs, attitudes and cultural traditions, privacy and protectiveness comprised perceived reasons for blocking intra-family health communications. Longitudinal data collected over 4 years showed families where blocking behavior was universally recognized and stable over time, as well as other families where blocking was less consistent. Self-blocking was observed among a significant minority of participating women. Blocking of health communications among family members with HBOC was variable, complex, and multifaceted. The reasons for blocking were heterogeneous; duration of the blocking appeared to depend on the reasons for blocking. Blocking often seemed to involve bi-directional feedback loops, in keeping with Lepore’s Social Constraints and Modulation Theory. Privacy and protectiveness predominated as explanations for long-term blocking.
