On the processing of arguments

This paper is concerned with the processing of informal arguments, that is, arguments involving probable truth. A model of informal argument processing is presented that is based upon Hample's (1977) expansion of Toulmin's (1958) model of argument structure. The model postulates that a claim activates an attitude, the two components forming a complex that in turn activates reasons. Furthermore, the model holds occurrence of the reason, or possibly the claim and the reason, activates values. Three experiments are described that provide support for the model.This research was supported by the Mellon Foundation and by the Office of Educational Research and Improvement of the Department of Education via an award for the Center for the Study of Learning to the Learning Research and Development Center.

The evolution of policy arguments in teachers' negotiations

Argument is a critical component in policy deliberations. In this study, negotiation is viewed as a type of policy deliberation, one characterized by attack and defense of proposals, interdependence between disputants, and mixed motives of cooperation and competition. Argument in negotiation, then, functions as a reason-giving activity to enact policy. Employing a category system based on rhetorical stasis, the researchers examine whether bargainers specialize in their use of argument types and whether this specialization remains consistent throughout a teacher-school board negotiation and whether it differs for the type of settlement of agenda items. Results of the study suggest that bargainers specialize in argument types at different times during the bargaining. In the early stages of negotiation, teachers center on harm and workability arguments to prepare their case and justify the merits of their proposals, but in the latter phases of bargaining they switch to arguments on implementation to reaffirm their demands and to prioritize issues. Board members, in the early stages, rely on disadvantage, workability, and implementation arguments to establish resistance points and to refute appeals for change, but in the latter stages of negotiation they employ harm-inherency and disadvantage arguments to weigh the costs of concessions and to rationalize the settlement. This study, then, supports the existence of phase variation in bargaining and argues for a developmental approach in deciphering how negotiators who hold antithetical positions reach mutually satisfactory settlements.     

The spatial contours of wellbeing: A content analysis of metaphor in academic discourse

Abstract

In thinking and talking about wellbeing, people often deploy spatial metaphors, such as identifying positive and negative affect with ‘up’ and ‘down’ respectively. However, there has not yet been a systematic investigation of how wellbeing is represented through metaphor. To shed light on this topic, a content analysis was conducted of spatial metaphors in academic discourse on wellbeing, focusing on recent editions of two leading journals, the Journal of Positive Psychology, and the British Journal of Clinical Psychology. Across 28 papers, 54 spatial metaphors were identified, grouped into four main categories: verticality; horizontality; configuration; and dynamism. Above all, wellbeing is associated with interior expansiveness, with positive valence usually attaching to vertical metaphors of height and depth, horizontal metaphors of width and breadth, and configuration metaphors of size and growth. The analysis thus offers valuable insights into the subjective dynamics of wellbeing.     

Validation of a category system for arguments in conflict discourse

Theories of individuation predict systematic differences in argumentative behavior between adolescent girls and their mothers. In order to reveal the nature and functions of this kind of discourse, two studies were carried out on 110 mother-daughter pairs. The second study (n=80) replicated and extended the first study (n=30) on an independent sample. The mother-daughter pairs were asked to discuss a subject that had recently been at issue between them. To assess the argumentative behavior, a category system was developed that reflects the functional character of utterances in discourse. The aim of the research was to test the reliability and validity of the category system. Daughters are assumed to verbalize their own needs and preferences to increase the differences to the mother, and to weaken or reject the mother's arguments in an effort to resist control. Mothers, on the other hand, are supposed to exert control over the behavior of their daughters but do so within bounds of mutuality. This should lead to verbal initiatives and attempts to explain, support and modify their positions and arguments. The data showed high reliability of the categorization of arguments. The categories also differentiated between mothers and daughters. Daughters were more likely to try to weaken and reject (and accept) the mother's arguments and to state preferences while mothers tried to support and explain their positions and to retain control by initiating questions and arguments to which the daughters responded.     

A family assessment based on the Social Relations Model

One purpose of family assessment is to formulate hypotheses that can guide clinical interventions. Family assessment is based on models about family functioning. In this paper the Social Relations Model ( Kenny and La Voie, 1984 ; SRM) is presented as such a model about family dynamics. Moreover, SRM provides statistical tools to underpin empirical hypotheses about family functioning. An SRM family assessment of a family with a child in child psychiatric care exemplifies the possibilities and limitations of this SRM approach to family assessment. The subject of the family assessment is family members' sense of influence in their family relationships.     

A functional-analytic model of analogy: a relational frame analysis

The aim of this study was to explore a behavior-analytic model of analogical reasoning, defined as the discrimination of formal similarity via equivalence-equivalence responding. In Experiment 1, adult humans were trained and tested for the formation of four three-member equivalence relations: A1-B1-C1, A2-B2-C2, A3-B3-C3, and A4-B4-C4. The B and C stimuli were three-letter nonsense syllables, and the A stimulus was a colored shape. Subjects were then successfully tested for equivalence-equivalence responding (e.g., matching B1/C1 to B2/C2 rather than B3/C4). These tasks were designed such that equivalence-equivalence responding might allow subjects to discriminate a physical similarity between the relations involved. Some participants (color subjects) received only equivalence-equivalence tasks in which they might discriminate a color relation, whereas others (shape subjects) were given tasks in which they might discriminate a shape relation. A control group received both types of task. In a subsequent test for the discrimination of formal similarity, color subjects matched according to color, shape subjects matched according to shape, and the control group showed no consistent matching pattern. In Experiment 2, adult humans showed a transformation of the functions of a block-sorting task via this basic model of analogy. Empirical and conceptual issues related to these results are discussed.     

Breast cancer representations in Canadian news media: a critical discourse analysis of meanings and the implications for identity

Despite the importance of critical media work, much is to be learned about breast cancer representations within media discourses and the implications for women’s identity construction. Building on research from Australia from a discursive perspective, this article used an eclectic approach to critical discourse analysis to explore the cultural construction of breast cancer in 25 detailed stories within Canada’s two national newspapers, The Globe and Mail and the National Post. Ten images accompanying stories and 17 advertisements/public service announcements were also analyzed to contextualize discourses and subject positions/identities within the stories. Analysis of this media affords the unique opportunity to explore taken for granted assumptions and prevailing meanings about breast cancer and the implications for subjectivity. Two primary discourses were identified: a discourse of biomedicine and a discourse of healthism. Subject positions identified included “breast cancer survivor,” “the good consumer,” and the “medical expert.” The psychological, social, political, and health promotion implications are discussed.     

Reflection in university and the employability agenda: a discourse analysis case study

In UK universities, reflection is promoted not only for its intrinsic value but also for instrumental purposes, for students to gain and demonstrate skills and attributes which are valued by employers. In this paper, I examine reflective writing produced by students seeking an award offered by the careers department of one university. By looking at the evaluative language choices made by the student writers, I shed light on some of their practices regarding self-representation and their articulations of experience. I provide a critical account of what reflective writing looks like in this particular setting, and interpret this in the broader context of the goal to foster reflection among higher education students. I argue that the reflective writing engendered by this particular context and task is different in key respects from the reflection which is commonly advocated as an element of personal, professional or academic development.     

A brain-inspired cognitive support model for stress reduction based on an adaptive network model

Stress is often seen as a negative factor which affects every individual’s life quality and decision making. To help avoid or deal with extreme emotions caused by an external stressor, a number of practices have been introduced. In the scope of this paper, we take three kinds of therapy into account: mindfulness, humor, and music therapy. This paper aims to see how various practices help people to cope with stress, using mathematical modelling. We present practical implementations in the form of client–server software, incorporating the computational model which describes therapy effects for overcoming stress based on quantitative neuropsychological research. The underlying network model simulates the elicitation of an extremely stressful emotion due to a strong stress-inducing event as an external stimulus, followed by a therapy practice simulation leading to a reduction of the stress level. Each simulation is based on user input and preferences, integrating a parameter tuning process; it fits a simulation for a particular user. The client–server architecture software which has been designed and developed completely fulfills this objective. It includes server part with embedded MATLAB interaction and API for client communication.     

A putative role for neurogenesis in neurocomputational terms: Inferences from a hippocampal model

New neurons are generated daily in the hippocampus during adult life. They are integrated into the existing neuronal circuits according to several factors such as age, physical exercise and hormonal status. At present, the role of these new neurons is debated. Computational simulations of hippocampal function allow the effects of neurogenesis to be explored, at least from a computational perspective. The present work implements a model of neurogenesis in the hippocampus with artificial neural networks, based on a standard theoretical model of biologically plausible hippocampal circuits. The performance of the model in retrieval of a variable number of patterns or memories was evaluated (episodic memory evaluation). The model increased, in a phase subsequent to initial learning, the number of granular cells by 30% relative to their initial number. In contrast to a model without neurogenesis, the retrieval of recent memories was very significantly improved, although remotes memories were only slightly affected by neurogenesis. This increase in the quality of retrieval of new memories represents a clear advantage that we attribute to the neurogenesis process. This advantage becomes more significant for higher storage loads. The model presented here suggests an important functional role of neurogenesis on learning and memory.     

A neurally plausible parallel distributed processing model of event-related potential word reading data

The Parallel Distributed Processing (PDP) framework has significant potential for producing models of cognitive tasks that approximate how the brain performs the same tasks. To date, however, there has been relatively little contact between PDP modeling and data from cognitive neuroscience. In an attempt to advance the relationship between explicit, computational models and physiological data collected during the performance of cognitive tasks, we developed a PDP model of visual word recognition which simulates key results from the ERP reading literature, while simultaneously being able to successfully perform lexical decision—a benchmark task for reading models. Simulations reveal that the model’s success depends on the implementation of several neurally plausible features in its architecture which are sufficiently domain-general to be relevant to cognitive modeling more generally.     

A closer look at first sight: Social relations lens model analysis of personality and interpersonal attraction at zero acquaintance

Based on a new theoretical framework—the Social Relations Lens Model—this study examined the influence of personality on real‐life attraction at zero acquaintance. A group of psychology freshmen (N = 73) was investigated upon encountering one another for the first time. Personality traits, attraction ratings and metaperceptions were assessed using a large round‐robin design (2628 dyads). In line with our model, personality differentially predicted who was a liker and who expected to be liked (perceiver effects), who was popular and who was seen as a liker (target effects), as well as who liked whom and who expected to be liked by whom (relationship effects). Moreover, the influence of personality on attraction was mediated by observable physical, nonverbal and audible cues. Results allowed a closer look at first sight and underline the importance of combining componential and process approaches in understanding the interplay of personality and social phenomena.

A computational model of spatial visualization capacity

Visualizing spatial material is a cornerstone of human problem solving, but human visualization capacity is sharply limited. To investigate the sources of this limit, we developed a new task to measure visualization accuracy for verbally-described spatial paths (similar to street directions), and implemented a computational process model to perform it. In this model, developed within the Adaptive Control of Thought-Rational (ACT-R) architecture, visualization capacity is limited by three mechanisms. Two of these (associative interference and decay) are longstanding characteristics of ACT-R’s declarative memory. A third (spatial interference) is a new mechanism motivated by spatial proximity effects in our data. We tested the model in two experiments, one with parameter-value fitting, and a replication without further fitting. Correspondence between model and data was close in both experiments, suggesting that the model may be useful for understanding why visualizing new, complex spatial material is so difficult.     

Innovation in therapeutic practice with ‘violent youth’: A discourse analysis of the non‐violent resistance approach

Introduction: The introduction of the innovative non‐violent resistance approach (NVR) at a multi‐agency service in east Kent, UK, has presented challenges in terms of the recruitment of the necessary wider professional support for the family, with some professionals seeing the approach as not child‐focused. Aims and objectives: To identify child‐focused themes among professionals, and to compare these with discourses used in NVR and, for comparison, in the Webster‐Stratton approach, to elucidate possible obstacles to the acceptance by professionals of NVR. Methods and analysis: A focus group of experienced professionals was convened to discuss what it means to be child‐focused, and a thematic analysis was conducted. Key texts from NVR and the Webster‐Stratton approach were selected and analysed using Foucauldian discourse analysis. Results: Being child‐focused was considered to require the child's voice being heard, at least by the parents. Power differentials and developmental issues were also highlighted in the discussion. The key text analyses suggests that the Webster‐Stratton approach is communicated through familiar ‘biomedical’ and ‘missionary’ discourses, while surprisingly NVR is communicated through a discourse of ‘war’ as well as the more familiar and child‐focused ‘family values’ discourse. Implications: The ‘war’ discourse used by NVR, in which violent young people are seen as aggressors and oppressors, challenges the traditional discourses of childhood formed around notions of innocence. The implications of these findings are discussed in relation to furthering the adoption of NVR as an effective way of working to help violent children of all ages.     

A test of the Dual Filial Piety model

Filial piety is a central concept in Confucianism, containing important ideas about how children should treat their parents. Research over the past two decades has resulted in conflicting findings over whether filial piety is beneficial or harmful to individual development. The Dual Filial Piety model integrates these conflicting findings and suggests neither assessment of filial piety is appropriate. The present study offers empirical evidence in support of the dual model and offers commentary on the role of filial piety in modern Chinese society and directions for future research.     

Conversational perspective of therapeutic outcomes: The importance of preference in the development of discourse

Major theme: Evaluation of therapeutic outcome. Logical development of the theme: We suggest a way for practitioners and researchers to assess if they are on track in conversing towards client preferred goals. We offer a critique of more conventional approaches to studying therapeutic progress, suggesting how a discursive (i.e. focused on interaction and language use) lens can address these limitations. Through this lens we examine therapeutic progress evident in ‘preference work’, where clients demonstrably indicate, imply, agree and disagree with where the therapeutic conversation is heading. Such ‘preference work’ offers a form of evidence of within‐session outcomes in a process of reaching larger client preferred outcomes. Authors’ point of view: We present the results of conversation analysis – a qualitative approach to the study of therapy – to illustrate our discursive perspective on therapy progress and change. Implications: we suggest a way for practitioners to assess if they are on track in conversing towards client preferred goals. We propose that our interactional perspective may significantly contribute to bridging practice and research in therapy.
