Simulating naturalistic instruction: the case for a voice mediated interface for assistive technology for cognition

A variety of brain pathologies can result in difficulties performing complex behavioural sequences. Assistive technology for cognition (ATC) attempts support of complex sequences with the aim of reducing disability. Traditional ATCs are cognitively demanding to use and thus have had poor uptake. A more intuitive interface may allow ATCs to reach their potential. Insights from psychological science may be useful to technologists in this area. We propose that an auditory-verbal interface is more intuitive than a visual interface and reduces cognitive demands on users. Two experiments demonstrate a novel ATC, the General User Interface for Disorders of Execution (GUIDE). GUIDE is novel because it simulates normal conversational prompting to support task performance. GUIDE provides verbal prompts and questions and voice recognition allows the user to interact with the GUIDE. Research with non-cognitively impaired participants and a single participant experiment involving a person with vascular dementia provide support for using interactive auditory-verbal interfaces. Suggestions for the future development of auditory-verbal interfaces are discussed

Textual indicators of deliberative dialogue: a systematic review of methods for studying the quality of online dialogues

High-quality online dialogues help sustain democracy. Deliberative theory, which predates the internet, provides the primary model for assessing the quality of online dialogues. It conceptualizes high-quality online dialogue as civil, rational, constructive, equal, interactive, and for the common good. More recently, advances in computation have driven an upsurge of empirical studies using automated methods for operationalizing online dialogue and measuring its quality. While related in their aims, deliberative theory and the wider empirical literature generally operate independently. To bridge the gap between the two literatures, we introduce Textual Indicators of Deliberative Dialogue (TIDDs). TIDDs are defined as text-based measures of online dialogue quality under a deliberative model (e.g., disagreement, incivility, justifications). In this study, we identified 123 TIDDs by systematically reviewing 67 empirical studies of online dialogue. We found them to have mid-low reliability, low criterion validity, and high construct validity for measuring two deliberative dimensions (civility and rationality). Our results highlight the limitations of deliberative theory for conceptualizing the variety of ways online dialogues can be operationalized. We report the most promising TIDDs for measuring the quality of online dialogue and suggest deliberative theory would benefit from altering its models in line with the broader empirical literature

Large D/H variations in bacterial lipids reflect central metabolic pathways

Large hydrogen-isotopic (D/H) fractionations between lipids and growth water have been observed in most organisms studied to date. These fractionations are generally attributed to isotope effects in the biosynthesis of lipids, and are frequently assumed to be approximately constant for the purpose of reconstructing climatic variables. Here, we report D/H fractionations between lipids and water in 4 cultured members of the phylum Proteobacteria, and show that they can vary by up to 500‰ in a single organism. The variation cannot be attributed to lipid biosynthesis as there is no significant change in these pathways between cultures, nor can it be attributed to changing substrate D/H ratios. More importantly, lipid/water D/H fractionations vary systematically with metabolism: chemoautotrophic growth (approximately −200 to −400‰), photoautotrophic growth (−150 to −250‰), heterotrophic growth on sugars (0 to −150‰), and heterotrophic growth on TCA-cycle precursors and intermediates (−50 to +200‰) all yield different fractionations. We hypothesize that the D/H ratios of lipids are controlled largely by those of NADPH used for biosynthesis, rather than by isotope effects within the lipid biosynthetic pathway itself. Our results suggest that different central metabolic pathways yield NADPH—and indirectly lipids—with characteristic isotopic compositions. If so, lipid δD values could become an important biogeochemical tool for linking lipids to energy metabolism, and would yield information that is highly complementary to that provided by ^(13)C about pathways of carbon fixation

Position exchange theory: a socio-material basis for discursive and psychological positioning

Dialogicality within discourse and the self has been widely observed and analyzed. But how does this dialogicality develop and change? And how is it related to society? We argue that people moving within their societies, specifically moving between social positions, which are institutionally sanctioned roles with situational demands, provides a social and material basis for dialogicality. Each social position sustains a psychological perspective, and thus people moving into a social position are stepping into the associated psychological perspective in a fundamentally embodied way. As people move between roles and situations in society they accumulate psychological orientations, and this, we argue, is the basis for the dialogical tensions within the self, discursive positioning, and also humans' abilities to orient to one another and empathize. We review literature on play, games, education, problem-solving, and life trajectories to demonstrate that exchanging social positions is an important developmental principle operating across the lifespan

Revisiting Milgram’s cyranoid method: experimenting with hybrid human agents

In two studies based on Stanley Milgram’s original pilots, we present the first systematic examination of cyranoids as social psychological research tools. A cyranoid is created by cooperatively joining in real-time the body of one person with speech generated by another via covert speech shadowing. The resulting hybrid persona can subsequently interact with third parties face-to-face. We show that naïve interlocutors perceive a cyranoid to be a unified, autonomously communicating person, evidence for a phenomenon Milgram termed the “cyranic illusion.” We also show that creating cyranoids composed of contrasting identities (a child speaking adult-generated words and vice versa) can be used to study how stereotyping and person perception are mediated by inner (dispositional) vs. outer (physical) identity. Our results establish the cyranoid method as a unique means of obtaining experimental control over inner and outer identities within social interactions rich in mundane realism

Imagination in human and cultural development

This book positions imagination as a central concept which increases the understanding of daily life, personal life choices, and the way in which culture and society changes. Case studies from micro instances of reverie and daydreaming, to utopian projects, are included and analysed. The theoretical focus is on imagination as a force free from immediate constraints, forming the basis of our individual and collective agency. In each chapter, the authors review and integrate a wide range of classic and contemporary literature culminating in the proposal of a sociocultural model of imagination. The book takes into account the triggers of imagination, the content of imagination, and the outcomes of imagination. At the heart of the model is the interplay between the individual and culture; an exploration of how the imagination, as something very personal and subjective, grows out of our shared culture, and how our shared culture can be transformed by acts of imagination. Imagination in Human and Cultural Development offers new perspectives on the study of psychological learning, change, innovation and creativity throughout the lifespan. The book will appeal to academics and scholars in the fields of psychology and the social sciences, especially those with an interes

Perspective-taking is two-sided: misunderstandings between people with Asperger’s syndrome and their family members

Misunderstandings are social in nature, always having two sides. Yet the misunderstandings experienced by people with Asperger’s syndrome are usually studied in terms of the individual with a diagnosis, with less emphasis on social relations. We use a two-sided methodology to map out misunderstandings within 22 dyads (n = 44) consisting of people with Asperger’s syndrome and their family members. Both sides of the relationship were asked about 12 topics in terms of one’s rating of Self, one’s rating of Other and one’s predicted rating by Other. The findings show that people with Asperger’s are able to predict lower scores from family members, despite disagreeing with their view, and that family members often over-estimate the extent to which their relatives with Asperger’s syndrome are egocentrically anchored in their own perspective. The research demonstrates that a two-sided methodology is viable, and it uses it to identify how representations of Asperger’s syndrome can both support and hinder social understanding within relationships affected by Asperger’s

Internalization: How culture becomes mind

Internalization, the process by which culture becomes mind, is a core concept in cultural psychology. However, since the 1990s it has also been the source of debate. Critiques have focused on the underlying metaphor of internal-external as problematic. It has been proposed that appropriation provides a better conceptualization, a term that focuses attention more on behavior and less on psychological processes. The present article reviews the debate and introduces the recent concepts of position exchange and symbolic resources. Position exchange focuses on the societal side of culture, on the way in which social situations shape people’s experiences. Symbolic resources focus on culture in terms of specific elements, such as books, films, and so on, which also shape people’s experiences. The key idea common to both position exchange and symbolic resources is that people move through culture, both physically and psychologically. Moving through culture shapes a series of experiences across the lifecourse, and these experiences “layer up” within individuals, forming a complex sedimentation of culture within individuals. In so far as culture is heterogeneous and fragmented, so the sedimented layers of experience will also be heterogeneous and fragmented, thus creating the tensions that underlie the dynamics of mind
