Brain activity supporting alternating speech for semantic words: simultaneous magnetoencephalographic recording.

Communication, especially conversation, is essential for human social life. Many previous studies have examined the neuroscientific underpinnings of conversation, i.e. language comprehension and speech production. However, conversation inherently involves two or more people, and unless two people actually interact with one another, the nature of the conversation cannot be truly revealed. Therefore, in this study, we used two magnetoencephalographs that were connected together, and simultaneously recorded brain activity while two people took turns speaking in a word association/alphabet completion task. We compared the amplitude modulation of the alpha- and beta-band rhythms within each of the 62 brain regions under semantic (word association; less predictable) and non-semantic (alphabet completion; more predictable) conditions. We found that the amplitudes of the rhythms were significantly different between conditions in a wide range of brain regions. Additionally, significant differences were observed in nearly the same group of brain regions after versus before each utterance, indicating that a wide range of brain areas is involved in predicting a conversation partner's next utterance. This result supports the idea that mentalizing, e.g. predicting another person's speech, plays an important role in conversation, and suggests that the neural network implicated in mentalizing extends over a wide range of brain regions.

Talking with strangers is surprisingly informative.

A meaningful amount of people's knowledge comes from their conversations with others. The amount people expect to learn predicts their interest in having a conversation (pretests 1 and 2), suggesting that the presumed information value of conversations guides decisions of whom to talk with. The results of seven experiments, however, suggest that people may systematically underestimate the informational benefit of conversation, creating a barrier to talking with-and hence learning from-others in daily life. Participants who were asked to talk with another person expected to learn significantly less from the conversation than they actually reported learning afterward, regardless of whether they had conversation prompts and whether they had the goal to learn (experiments 1 and 2). Undervaluing conversation does not stem from having systematically poor opinions of how much others know (experiment 3) but is instead related to the inherent uncertainty involved in conversation itself. Consequently, people underestimate learning to a lesser extent when uncertainty is reduced, as in a nonsocial context (surfing the web, experiment 4); when talking to an acquainted conversation partner (experiment 5); and after knowing the content of the conversation (experiment 6). Underestimating learning in conversation is distinct from underestimating other positive qualities in conversation, such as enjoyment (experiment 7). Misunderstanding how much can be learned in conversation could keep people from learning from others in daily life.

Relational diversity in social portfolios predicts well-being.

We document a link between the relational diversity of one's social portfolio-the richness and evenness of relationship types across one's social interactions-and well-being. Across four distinct samples, respondents from the United States who completed a preregistered survey (n = 578), respondents to the American Time Use Survey (n = 19,197), respondents to the World Health Organization's Study on Global Aging and Adult Health (n = 10,447), and users of a French mobile application (n = 21,644), specification curve analyses show that the positive relationship between social portfolio diversity and well-being is robust across different metrics of well-being, different categorizations of relationship types, and the inclusion of a wide range of covariates. Over and above people's total amount of social interaction and the diversity of activities they engage in, the relational diversity of their social portfolio is a unique predictor of well-being, both between individuals and within individuals over time.

Fast response times signal social connection in conversation.

Clicking is one of the most robust metaphors for social connection. But how do we know when two people "click"? We asked pairs of friends and strangers to talk with each other and rate their felt connection. For both friends and strangers, speed in response was a robust predictor of feeling connected. Conversations with faster response times felt more connected than conversations with slower response times, and within conversations, connected moments had faster response times than less-connected moments. This effect was determined primarily by partner responsivity: People felt more connected to the degree that their partner responded quickly to them rather than by how quickly they responded to their partner. The temporal scale of these effects (<250 ms) precludes conscious control, thus providing an honest signal of connection. Using a round-robin design in each of six closed networks, we show that faster responders evoked greater feelings of connection across partners. Finally, we demonstrate that this signal is used by third-party listeners as a heuristic of how well people are connected: Conversations with faster response times were perceived as more connected than the same conversations with slower response times. Together, these findings suggest that response times comprise a robust and sufficient signal of whether two minds "click."

Misplaced Divides? Discussing Political Disagreement With Strangers Can Be Unexpectedly Positive.

Differences of opinion between people are common in everyday life, but discussing those differences openly in conversation may be unnecessarily rare. We report three experiments (N = 1,264 U.S.-based adults) demonstrating that people's interest in discussing important but potentially divisive topics is guided by their expectations about how positively the conversation will unfold, leaving them more interested in having a conversation with someone who agrees versus disagrees with them. People's expectations about their conversations, however, were systematically miscalibrated such that people underestimated how positive these conversations would be-especially in cases of disagreement. Miscalibrated expectations stemmed from underestimating the degree of common ground that would emerge in conversation and from failing to appreciate the power of social forces in conversation that create social connection. Misunderstanding the outcomes of conversation could lead people to avoid discussing disagreements more often, creating a misplaced barrier to learning, social connection, free inquiry, and free expression.

Disagreement Gets Mistaken for Bad Listening.

It is important for people to feel listened to in professional and personal communications, and yet they can feel unheard even when others have listened well. We propose that this feeling may arise because speakers conflate agreement with listening quality. In 11 studies (N = 3,396 adults), we held constant or manipulated a listener's objective listening behaviors, manipulating only after the conversation whether the listener agreed with the speaker. Across various topics, mediums (e.g., video, chat), and cues of objective listening quality, speakers consistently perceived disagreeing listeners as worse listeners. This effect persisted after controlling for other positive impressions of the listener (e.g., likability). This effect seemed to emerge because speakers believe their views are correct, leading them to infer that a disagreeing listener must not have been listening very well. Indeed, it may be prohibitively difficult for someone to simultaneously convey that they disagree and that they were listening.

How the Listener's Attention Dynamically Switches Between Different Speakers During a Natural Conversation.

The neural mechanisms underpinning the dynamic switching of a listener's attention between speakers are not well understood. Here we addressed this issue in a natural conversation involving 21 triadic adult groups. Results showed that when the listener's attention dynamically switched between speakers, neural synchronization with the to-be-attended speaker was significantly enhanced, whereas that with the to-be-ignored speaker was significantly suppressed. Along with attention switching, semantic distances between sentences significantly increased in the to-be-ignored speech. Moreover, neural synchronization negatively correlated with the increase in semantic distance but not with acoustic change of the to-be-ignored speech. However, no difference in neural synchronization was found between the listener and the two speakers during the phase of sustained attention. These findings support the attenuation model of attention, indicating that both speech signals are processed beyond the basic physical level. Additionally, shifting attention imposes a cognitive burden, as demonstrated by the opposite fluctuations of interpersonal neural synchronization.

Youth participation in substance use prevention: A national profile, 2011-2019.

PURPOSE: Prevention efforts are critical to avoid the negative consequences of substance use in adolescents. This study aimed to examine national trends and sociodemographic differences in adolescents' participation in school-based substance use prevention (SUP) education, community-based SUP programs, as well as family conversations about substance use. METHODS: Publicly available data for adolescents aged 12-17 from the annual cross-sectional surveys of the National Survey on Drug Use and Health 2011-2019 were analyzed. RESULTS: Across the survey years, up to 74.9%, 12.2%, and 58.1% of adolescents reported having participated in school-based SUP education, community-based SUP programs, and family conversations about the danger of substance use in the past-year, respectively. From 2011 to 2019, statistically significant decreases were observed in adolescents' participation in school-based SUP education (OR = 0.97, 95% CI: 0.96, 0.98, p < 0.001) and community-based SUP programs (OR = 0.98, 95% CI: 0.97, 0.99, p < 0.001). Meanwhile, no significant changes were observed in adolescents' participation in family conversations about the dangers of substance use. Overall, lower levels of participation in school-based and community-based SUP programs were found in adolescents aged 16-17. Adolescents living in rural areas showed lower levels of participation in school-based SUP programs and family conversations about SUP. Racial/ethnic minority adolescents overall were less likely to participate in conversations with parents about SUP than Whites. CONCLUSIONS: Further development and implementation of developmentally appropriate, gender-specific, culturally sensitive, and contextually informed SUP programs at school, community, and family levels are needed.

Parental expressions of love in Chinese American immigrant families: Implications for children's attachment security.

Harlow's seminal work on the nature of attachment focused on the importance of warm, responsive, and loving relationships in children's healthy development. While the need for love and care is arguably universal, the ways in which these emotions are expressed can vary across cultural contexts. We examined how Chinese American parents' expressions of love were associated with children's attachment security. A total of 110 Chinese American immigrant parent-child dyads (children 7-11 years old, 49% girls) participated in 3-min conversations in which parents were instructed to communicate love and care. Proposition-level analyses in speech (total 8825 propositions) identified three types of affection: training (guan and chiao shun); relational affection (qin); and validation (acceptance and encouragement of child's own expression of emotion, thoughts, and behaviors). Higher training was observed in parents with lower American orientation and lower income. Higher relational affection was observed in parents with lower income. Higher validation was observed in parents with higher income. Using path analyses, training and validation were found to be positively associated with children's attachment security beyond parenting styles. Effects of parents' relational affection were moderated by children's American orientation. Results demonstrate how immigrant parents draw on multiple cultural scripts to express love and care. These findings expand traditional concepts of parental love in immigrant families and illustrate how bicultural expressions of love can shape attachment security in middle childhood. A video abstract of this article can be viewed at https://youtu.be/HqUfIDxkFsE RESEARCH HIGHLIGHTS: Analyses of parent-child discussions identified three parental affection styles (i.e., training, relational affection, and validation) as expressions of love and care in Chinese American immigrant families. Training and validation were positively associated with children's attachment security. Relational affection was associated with lower attachment security for children with higher American cultural orientation, suggesting the effects of parent-child expressions of love are shaped by acculturation.

Drawing the abdominal pain: A powerful tool to distinguish between organic and functional abdominal pain.

OBJECTIVES: Abdominal pain (AP) in children imposes a large economic burden on the healthcare system. Currently, there are no reliable diagnostic tools to differentiate between organic and functional disorders. We hypothesized from previous research that the analysis of patients' graphic expression of subjective symptoms as well as their interactional behavior adds new ways to differentiate between functional and organic AP. METHODS: Conversation analyses of physician-patient-encounters and graphical expression of AP-based pain were performed. RESULTS: Twenty-two interactions were recorded and analyzed. Fifteen children were diagnosed with organic AP and seven with functional AP. We found marked differences between children with organic and functional AP. For example, all 15 children with organic AP saw the task of drawing a picture of the pain during the interview as a duty, whereas the seven children with functional AP took this as an opportunity to provide detailed descriptions about the nature of the pain, the circumstances, and how the AP impaired their quality of life. CONCLUSION: Analysis of patients' interaction strategies in response to the painting task provides relevant clues as to whether AP is functional or requires further workup for organic causes.

Rethinking parameters of "success" in breaking bad news conversations from patient's perspective: the successful delivery process model.

PURPOSE: Studies that focus on improving the difficult process of breaking bad news in oncology should include the patient perspective and be guided by appropriate outcome measures. Endpoints such as "patient satisfaction" fall short to capture the complex nature of breaking bad news (BBN) conversations. However, this is true of many studies. The present study attempts to develop a framework model from a new, patient-centered perspective, which can be applied equally in clinical practice and in education. METHODS: Semi-structured in-depth interviews with twelve cancer patients were conducted. Transcripts were analyzed by "qualitative content analysis" following Mayring. Outcomes were further extrapolated in interpretational steps, and a model of "success" from patients view in BBN was developed. RESULTS: Two central needs of the patients could be identified: understanding and feelings. Their fulfillment depends on two groups of variables: first, structural characteristics, such as the inevitable shock, individuality, and processability; second, strongly influenceable variables, such as relationship, transfer of knowledge, and atmosphere. From these results, a framework model for successful breaking of bad news from the patient's perspective was developed: The successful delivery process model (SDP model). CONCLUSION: As a basic model for the framework for breaking bad news from the patient's perspective, the SDP model can be applied to many different situations in oncology and help to frame the difficult conversations by tailoring the BBN conversations on determinants that favorably influence the process in a patient centered manner. In this sense, the model can be useful in clinical practice as well as in education.

Family science capital moderates gender differences in parent-child scientific conversation.

This study examined whether variation in parent-child conversations about scientific processes can be explained by child gender and the science-related resources available to parents, known as scientific capital. Parents of 4- and 5-year-old children (N = 70) from across the United States completed a survey of science capital and were then videotaped with their children at home interacting with two science activities (i.e., balance scale and circuit toy). Videos were transcribed and analyzed for parents' science process language. Results indicated that parents' science process language occurred significantly more often during conversations with boys, among families with higher levels of scientific capital, and during the scale activity. Gender differences in science process language were not apparent at higher levels of science capital and during the scale activity. These effects speak to the need for measuring child, family, and contextual characteristics when identifying factors that promote children's early science engagement and learning. Results are discussed in terms of future interventions that could build scientific capital as a means to counteract stereotypes around gender and science.

Associations between parents' autonomy supportive management language and children's science, technology, engineering, and mathematics talk during and after tinkering at home.

We conducted a time series analysis of parents' autonomy supportive and directive language and parents' and children's STEM (science, technology, engineering, and mathematics) talk during and after a problem-solving activity (i.e., tinkering). Parent and child dyads (N = 61 children; Mage = 8.10 years; 31 boys; 54% White) were observed at home via Zoom. After tinkering, a researcher elicited children's reflections, and approximately 2 weeks later dyads reminisced together about the experience. During tinkering, the more autonomy supportive STEM talk parents used in 1 min, the more children talked about STEM in the next minute. During reminiscing, parents' autonomy support was also associated with children's STEM talk. Results suggest the importance of considering how both the content and style of parents' talk can support children's STEM engagement.

Advanced theory of mind and children's prosocial lie-telling in middle childhood: A training study.

Children's advanced theory of mind (AToM) is concurrently associated with their prosocial lie-telling. However, the causal link between AToM and prosocial lie-telling has not yet been demonstrated. To address this gap, the current study adopted a training paradigm and investigated the role of AToM in children's prosocial lie-telling in middle childhood. A total of 66 9- and 10-year-old children who did not demonstrate any prosocial lie-telling in a disappointment gift paradigm at the baseline were recruited and randomly assigned to either the experimental group (n = 32) or an active control group (n = 34). The experimental group underwent a conversation-based training program of four sessions. The results showed significantly greater gains in AToM at the posttest for the experimental group children compared with the control group children, controlling for family socioeconomic status, children's literacy score, working memory, and inhibition. More important, the experimental group children were more likely to tell prosocial lies than the control group, even after controlling for the pretest AToM and other covariates. However, the training effects faded at the 6-month follow-up test after the training's completion. These findings provide the first evidence for the causal role of AToM in the development of prosocial lie-telling in middle childhood. The fade-out effect is discussed in the context of educational interventions.

My anesthesia Choice-HF: development and preliminary testing of a tool to facilitate conversations about anesthesia for hip fracture surgery.

BACKGROUND: Patients often desire involvement in anesthesia decisions, yet clinicians rarely explain anesthesia options or elicit preferences. We developed My Anesthesia Choice-Hip Fracture, a conversation aid about anesthesia options for hip fracture surgery and tested its preliminary efficacy and acceptability. METHODS: We developed a 1-page, tabular format, plain-language conversation aid with feedback from anesthesiologists, decision scientists, and community advisors. We conducted an online survey of English-speaking adults aged 50 and older. Participants imagined choosing between spinal and general anesthesia for hip fracture surgery. Before and after viewing the aid, participants answered a series of questions regarding key outcomes, including decisional conflict, knowledge about anesthesia options, and acceptability of the aid. RESULTS: Of 364/409 valid respondents, mean age was 64 (SD 8.9) and 59% were female. The proportion indicating decisional conflict decreased after reviewing the aid (63-34%, P < 0.001). Median knowledge scores increased from 50% correct to 67% correct (P < 0.001). 83% agreed that the aid would help them discuss options and preferences. 76.4% would approve of doctors using it. CONCLUSION: My Anesthesia Choice-Hip Fracture decreased decisional conflict and increased knowledge about anesthesia choices for hip fracture surgery. Respondents assessed it as acceptable for use in clinical settings. PRACTICE IMPLICATIONS: Use of clinical decision aids may increase shared decision-making; further testing is warranted.

Remembering conversation in group settings.

Individuals can take on various roles in conversation. Some roles are more active, with the participant responsible for guiding that conversation in pursuit of the group's goals. Other roles are more passive, like when one is an overhearer. Classic accounts posit that overhearers do not form conversational common ground because they do not actively participate in the communication process. Indeed, empirical findings demonstrate that overhearers do not comprehend conversation as well as active participants. Little is known, however, about long-term memory for conversations in overhearers. Overhearers play an important role in legal settings and dispute resolution, and it is critical to understand how their memory differs in quality and content from active participants in conversation. Here we examine - for the first time - the impact of one's conversational role as a speaker, addressee, or overhearer on subsequent memory for conversation. Data from 60 participants recalling 60 conversations reveal that after a brief delay, overhearers recall significantly less content from conversation compared to both speakers and addressees, and that the content they do recall is less accurately sourced to its actual contributor. Mnemonic similarity is higher between active conversational participants than between active participants and overhearers. These findings provide key support for the hypothesis that the process of forming common ground in interactive conversation shapes and supports memory for that conversation.

Claiming and attributing (dis)taste: Issues of sharing a meal as a competent member.

Eating together is a primordial social activity with robust normative expectations. This study examines a series of instances where appreciative elements about the food during a shared meal are treated as noticeably absent and where some of the participants are attributed to exhibit a negative stance towards the food, which furthermore is used as a resource for engaging in membership categorization. Situated within the cognate approaches of ethnomethodology and conversation analysis, this study draws on video recordings of an integrated language and cooking workshop organized for immigrants in the French speaking part of Switzerland. The participants include a French teacher, two chefs and five immigrant women with various native languages. The detailed sequential, multimodal analysis details and explains how the participants treat gustatory features of eating as publicly available and accountable, and how the absence of evaluative elements contribute to the situated achievement of a plural "you" as a group that does not like "this" food. Ascribing (dis)taste for food on behalf of others, occasions accounts for just how to eat, showing the strong normative features that make up to the recognizability of sharing a meal as a competent member - including how sensorial experiences are evaluated and expressed. In this way, this study contributes to our understanding of the (non)ordinary features of eating together as a situated, embodied achievement and social institution that is built in and through interaction.

Mother-child memory conversation and children's independent memory: the roles of maternal characteristics.

Mother-child memory conversations are a nuanced and important factor in children's memory development. The current study focuses on maternal characteristics that are related to individual differences in maternal elaborative style. It also examines the role of maternal elaborative style in children's elaborativeness in the context of reminiscing and recounting. Two hundred and nine Turkish mothers (Mage = 36.32, SD = 4.99) and their 5- to 6-year-olds (Mage in months = 66.88, SD = 4.04) (110 girls, 99 boys) participated in the current study. Results revealed that maternal individuation and balanced self-construal type predicted maternal elaborativeness, which in turn predicted child elaborativeness in reminiscing and recounting. Yet, such a relation was not observed for maternal attachment styles or sensitivity. Findings suggested the importance of maternal individuation and balanced self-construal for mothers' and children's elaborativeness in memory conversations.

The role of a community conversation intervention in reducing stigma related to lower limb lymphoedema in Northern Ethiopia.

BACKGROUND: Stigma related to lower-limb lymphoedema poses a major psychosocial burden to affected persons and acts as a barrier to them accessing morbidity management and disability prevention (MMDP) services. Community Conversation (CC), which actively engages community members and disseminates health information amongst them, is believed to break the vicious cycle of stigma by enhancing disease-related health literacy at the community level. METHODS: A quasi-experimental study was conducted in Northern Ethiopia to assess the role of the CC intervention in reducing stigma. In two control districts, a comprehensive and holistic MMDP care package was implemented that included physical health, mental health and psychosocial interventions, whilst in the intervention district the CC intervention was added to the MMDP care package. A total of 289 persons affected by lymphoedema and 1659 community members without lymphoedema were included in the study. RESULTS: Over the course of the intervention, in all sites, community members' knowledge about the causes of lymphoedema increased, and perceived social distance and stigmatizing attitudes towards people with lymphoedema decreased in the community, whilst experienced and internalized stigma decreased amongst affected persons. There were no significant changes for perceived social support. However, the changes were greater in the control sites overall, i.e. those districts in which the holistic care package was implemented without CC. CONCLUSION: The findings suggest that the CC intervention provides no additional stigma reduction when used alongside a holistic MMDP care package. Provision of comprehensive and holistic MMDP services may be adequate and appropriate to tackle stigma related to lower-limb lymphoedema in a resource-constrained setting like Ethiopia.

Enhancing patient informed consent in elective skin cancer surgeries: a comparative study of traditional and digital approaches in a German public hospital.

BACKGROUND: This study aims to investigate the integration of modern sources of patient information, such as videos, internet-based resources, and scientific abstracts, into the traditional patient informed consent process in outpatient elective surgeries. The goal is to optimize the informed consent experience, enhance patient satisfaction, and promote shared decision making (SDM) between patients and surgeons. By exploring different patient informed consent formats and their impact on patient satisfaction, this research seeks to improve healthcare practices and ultimately enhance patient outcomes. The findings of this study will contribute to the ongoing efforts to improve the informed consent process in public hospitals and advance patient-centred care. METHODS: Data collection occurred at the day care clinic of a prominent German public hospital, forming an integral component of a prospective clinical investigation. The study exclusively focused on individuals who had undergone surgical intervention for skin cancer. For the purpose of meticulous data examination, the statistical software SPSS version 21 was harnessed. In the course of this study, a chi-square test was aptly employed. Its purpose was to scrutinize the nuances in patient experiences pertaining to informed consent across four distinct categories, viz., oral informed consent discussion (Oral ICD), written informed consent discussion (Written ICD), video-assisted informed consent discussion (video-assisted ICD), and digitally assisted informed consent discussion (digital-assisted ICD). The primary dataset of this inquiry was diligently gathered via a structured questionnaire administered to a targeted cohort of 160 patients. Within this sample, a balanced representation of genders was observed, encompassing 82 males and 78 females. Their collective age span ranged from 18 to 92 years, with an average age of 71 years. A randomized selection methodology was employed to include participants in this study during the period spanning from July 2017 to August 2018. RESULTS: Significant differences were observed across the groups for all research questions, highlighting variations in patient responses. Video-assisted and digital-assisted IC were rated as superior in patient satisfaction with information compared to written and oral IC. Demographic profiles of the four study groups were found to be comparable. CONCLUSION: The findings of this study indicate that the incorporation of digital technologies in the informed consent process can enhance patient understanding during outpatient elective skin cancer surgeries. These results have important implications for increasing patient satisfaction and improving the SDM process within the hospital environment.
