Exploring collaborative problem solving in adulthood

Collaborative problem solving occurs in situations in which two or more individuals cooperate in appraising, representing, and solving a variety of cognitive tasks. Collaborative groups are the context for much everyday cognitive activity in adulthood. Collaboration has been explored as a means through which older adults may maintain high levels of performance, perhaps compensating for individual-level cognitive and neurological decline. This study explored the effects of collaboration (group size) and adult age on solving both fixed- and unrestricted-alternatives 20 Questions tasks. Younger (M=24.3 years) and older (M=67.9 years) adults were randomly assigned to one of three homogeneous group size conditions: individuals, dyads, and tetrads. Results indicated some dissociation between individual-level performance (poorer for older adults) and collaborative performance (better for older adults). For the fixed-alternatives task, older adults produced more of the relatively inefficient hypothesis-scanning questions than did younger adults. In contrast, older collaborative groups produced more of the efficient constraint-seeking questions than hhpothesis-scanning questions, and an amount equivalent to that of younger adults. Overall performance for the difficult unrestricted-alternatives task was less efficient for both younger and older adults. The roles of task type, group characteristics, and adult age are discussed.

Embodied narratives in becoming a counselling trainer: an autoethnographic study

This autoethnographic study addresses the newly appointed counselling trainer's question ‘How did I get here?’ The procedure is described, and findings are presented as partial narratives of the Wounded Dancer, poems and prose written from different voices. Themes are revealed of love, healing, risk taking, unconventionality, physicality and overcoming physical limitations. ‘Wounded healer’ stories are inscribed alongside ‘powerful body’/‘subversive body’ stories. The role of the father is considered in facilitating these stories, including the tomboy throwing off ‘definitions of what it means to be a girl’. The study is evaluated in terms of Richardson's (2000) criteria. One contribution to knowledge lies in the methodology's potential application to research-led learning and teaching with counsellor education.     

Integrated Primary Care: An Inclusive Three-World View Through Process Metrics and Empirical Discrimination

Integrating behavioral health services within the primary care setting drives higher levels of collaborative care, and is proving to be an essential part of the solution for our struggling American healthcare system. However, justification for implementing and sustaining integrated and collaborative care has shown to be a formidable task. In an attempt to move beyond conflicting terminology found in the literature, we delineate terms and suggest a standardized nomenclature. Further, we maintain that addressing the three principal worlds of healthcare (clinical, operational, financial) is requisite in making sense of the spectrum of available implementations and ultimately transitioning collaborative care into the mainstream. Using a model that deconstructs process metrics into factors/barriers and generalizes behavioral health provider roles into major categories provides a framework to empirically discriminate between implementations across specific settings. This approach offers practical guidelines for care sites implementing integrated and collaborative care and defines a research framework to produce the evidence required for the aforementioned clinical, operational and financial worlds of this important movement.     

回忆任务对合作抑制和错误修剪的调节——情绪效价和编码水平的影响

前人在项目回忆条件的合作记忆研究中记录到明显的合作抑制和错误修剪,背景提取条件的相关研究尤显不足;同时,情绪效价和编码水平对两类现象调节的研究尚未涉及。为此,本文在两个实验中采用经典合作记忆研究范式,以不同情绪效价的词汇为实验材料并以词汇在学习阶段的呈现颜色为背景展开研究。实验1和实验2分别在学习阶段采用了深编码和浅编码任务,回忆阶段则均含项目回忆(回忆已学词汇)和背景提取(回忆词汇在学习阶段的呈现颜色)两种任务。采用深编码条件的实验1的结果显示,项目回忆比背景提取条件的合作抑制更强、错误修剪更弱,回忆任务与词汇情绪效价交互影响合作抑制强度;采用浅编码条件的实验2则发现错误修剪在两种任务间的差异不显著。两实验的联合分析显示,回忆任务与编码水平交互影响合作抑制和错误修剪强度。上述结果表明:回忆任务对合作抑制和错误修剪的调节支持双重加工模型;回忆任务与情绪效价对合作抑制强度的交互影响支持权衡说,且与双重加工模型相吻合;回忆任务与编码水平交互影响合作抑制和错误修剪强度。     

Antecedents of trust in the sharing economy: A systematic review

Users and potential users of the sharing economy need to place a considerable amount of trust in both the person and the platform with which they are dealing. The consequences of transaction partners’ opportunism may be severe, for example damage to goods or endangered personal safety. Trust is, therefore, a key factor in overcoming uncertainty and mitigating risk. However, there is no thorough overview of how trust is developed in this context. To understand how the trust of users in the sharing economy is influenced, we performed a systematic literature review. After screening, 45 articles were included in a qualitative synthesis in which the results were grouped according to a well‐established trust typology. The results show various antecedents of trust in the sharing economy (e.g. reputation, trust in the platform, and interaction experience) related to multiple entities (i.e. seller, buyer, platform, interpersonal, and transaction). Trust in this economy is often reduced to the use of reputation systems alone. However, our study suggests that trust is much more complex than that and extends beyond reputation. Furthermore, our review clearly shows that research on trust in the sharing economy is still scarce and thus more research is needed to understand how trust is established in this context. Our review is the first that brings together antecedents of trust in online peer‐to‐peer transactions and integrates these findings within an existing framework. Additionally, the study suggests directions for future research in order to advance the understanding of trust in the sharing economy.     

Representations of guidance counselors,psychologists, and psychoeducators regarding psychological assessment

IntroductionSocial representations related to collaborative/therapeutic and information-gathering assessment could explain some psychological assessment practices. However, no other study has attempted to examine the actual place of these models in psychological assessment practices.ObjectiveThe goal of this study was to examine the social representations of different groups of professionals with regard to their preferred approach to psychological assessment.MethodA latent profile analysis was conducted on a sample of licensed Canadian guidance counselors (n = 382), psychologists (n = 235), and psychoeducators (n = 97).ResultsResults revealed three psychological assessment profiles, which significantly differ in terms of a few social factors. Results also showed that some psychological assessment practices differ across profiles.ConclusionThis study provides a better understanding of psychometric instruments users’ approaches to assessment and the influence of social factors.     

Modelling change in self-narratives and embodied experience: A multicase study and autoethnography

The article documents a multicase study of the researcher’s own clinical work with four clients who each presented with embodied expressions of distress. The researcher practised within a ‘narrative-dialogical’ framework and set out to build theories of therapeutic change. However, a parallel thesis emerged during the project: an autoethnographic account in which the researcher’s uses of supervision, personal therapy, dreams and life events capture data on the ways in which the therapist’s theories of change are modelled in the therapeutic space—with varying degrees of confidence and success. Sessions were audio-recorded and coded for qualitative markers indicating the emergence of novel self-narratives. A reflexive narrative running throughout the work highlights the superordinate role of reflexivity in theory development. Therapeutic change was typified by an evolving internalised map of self and world, with corresponding change in embodied experience. The article highlights techniques deployed by the therapist in highlighting and building upon moments of innovation with the therapeutic process. As an analysis of one therapist’s practice and the experiences of their clients, the study generates theories for ongoing exploration and study. The continuous evolution of change concepts reflects the theory-building work of clinicians in their everyday practice. The study highlights the use of self as research instrument and offers a candid and intimate example of how practitioner research might be structured and delivered.     

Students' online collaborative intention for group projects: Evidence from an extended version of the theory of planned behaviour

Given the increasing use of web technology for teaching and learning, this study developed and examined an extended version of the theory of planned behaviour (TPB) model, which explained students' intention to collaborate online for their group projects. Results indicated that past experience predicted the three antecedents of intention, while past behaviour was predictive of subjective norm and perceived behavioural control. Moreover, the three antecedents (attitude towards e‐collaboration, subjective norm and perceived behavioural control) were found to significantly predict e‐collaborative intention. This study explored the use of the “remember” type of awareness (i.e. past experience) and evaluated the value of the “know” type of awareness (i.e. past behaviour) in the TPB model.     

Conflict and metacognitive control: the mismatch-monitoring hypothesis of how others' knowledge states affect recall

Information about others' success in remembering is frequently available. For example, students taking an exam may assess its difficulty by monitoring when others turn in their exams. In two experiments, we investigated how rememberers use this information to guide recall. Participants studied paired associates, some semantically related (and thus easier to retrieve) and some unrelated (and thus harder). During a subsequent cued recall test, participants viewed fictive information about an opponent's accuracy on each item. In Experiment 1, participants responded to each cue once before seeing the opponent's performance and once afterwards. Participants reconsidered their responses least often when the opponent's accuracy matched the item difficulty (easy items the opponent recalled, hard items the opponent forgot) and most often when the opponent's accuracy and the item difficulty mismatched. When participants responded only after seeing the opponent's performance (Experiment 2), the same mismatch conditions that led to reconsideration even produced superior recall. These results suggest that rememberers monitor whether others' knowledge states accord or conflict with their own experience, and that this information shifts how they interrogate their memory and what they recall.
