Latent trait models and dichotomization of graded responses

This paper discusses thecompatibility of the polychotomous Rasch model with dichotomization of the response continuum. It is argued that in the case of graded responses, the response categories presented to the subject are essentially an arbitrary polychotomization of the response continuum, ranging for example from total rejection or disagreement to total acceptance or agreement of an item or statement. Because of this arbitrariness, the measurement outcome should be independent of the specific polychotomization applied, for example, presenting a specific multicategory response format should not affect the measurement outcome. When such is the case, the original polychotomous model is called compatible with dichotomization.A distinction is made between polychotomization or dichotomization before the fact, that is, in constructing the response format, and polycho- or dichotomization after the fact, for example in dichotomizing existing graded response data.It is shown that, at least in case of dichotomization after-the-fact, the polychotomous Rasch model is not compatible with dichotomization, unless a rather special condition of the model parameters is met. Insofar as it may be argued that dichotomization before the fact is not essentially different from dichotomization after the fact, the value of the unidimensional polychotomous Rasch model is consequently questionable. The impact of our conclusion on related models is also discussed.     

A taxonomy of item response models

A number of models for categorical item response data have been proposed in recent years. The models appear to be quite different. However, they may usefully be organized as members of only three distinct classes, within which the models are distinguished only by assumptions and constraints on their parameters. “Difference models” are appropriate for ordered responses, “divide-by-total” models may be used for either ordered or nominal responses, and “left-side added” models are used for multiple-choice responses with guessing. The details of the taxonomy and the models are described in this paper. The present study was supported in part by two postdoctoral fellowships awarded to Lynne Steinberg: an Educational Testing Service Postdoctoral Fellowship at ETS, Princeton, NJ and an NIMH Individual National Research Service Award at Stanford University, Stanford, CA.

A temporal limit on the effect of future food on current performance in an analogue of foraging and welfare

Rats obtained access to food twice each 24-hour period. The first session was a work session in which food was available on a progressive-ratio schedule. During the second session, which occurred between 1 and 23 hours after the work session, food was freely available up to a fixed total intake each 24 hours. The situation resembled elements of several real world circumstances, including the choice between continuing to forage in a rapidly depleting patch and waiting for a better patch, and between working now and receiving a guaranteed income later. The purpose of the experiment was to explore the time period over which future access to reward could affect current responding. Contrary to what might be expected from recent theorizing, anticipation of future food delayed by an hour or more after the start of the work session had no effect on current performance. Food intake was high and constant during work sessions except for a prefeeding effect that occurred when the free session closely preceded the next day's work session. Also, an increase in the difficulty of the work schedule increased the amount of work and the maximum price paid for food as if the work session were the only time food was available. The results indicate the importance of considering temporal limits in theories that require animals to integrate input over time to determine the allocation of resources among alternatives.     

James and Carnap on philosophical systems and the role of temperaments

The relationship between American pragmatism and logical empiricism is complicated at best. The received view is that by around the late 1930s or early 1940s pragmatism had been replaced, supplanted, or eclipsed by the younger and more logic-oriented form of empiricism developed in interwar Vienna. Recently, however, this picture has been challenged, and this paper offers further reasons for thinking that the received view is inadequate. Through a critical examination of William James's Pragmatism and “The Sentiment of Rationality” and Rudolf Carnap's “Elimination of Metaphysics Through Logical Analysis of Language” and other works, the paper builds a case for the existence of a rather striking correspondence between the work of one of pragmatism's most vaunted figures and the thought of logical empiricism's most famous advocate. Not only were both philosophers interested in what might be called metaphilosophy or the psychology of philosophy, both held very similar deflationary views.     

Collective Trauma,Implicit Memories,the Body,and Active Imagination in Jungian Analysis1

This presentation attempts to show the healing potential underlying the inclusion of the patient's body in the analytic process, while honouring and revisiting the understanding of the psyche-body connection described by Jung in his early work. In addition, the author offers reflections on the impact of collective trauma whose aftermath, among others, has been the disappearance of thousands of people, consequently breaking the family genealogy, leaving hundreds of children stripped of their roots and true identity. Referencing clinical material, the author describes how the process of translation and integration—from the sensory-perceptual to the conceptual-symbolic—can be halted on account of collective trauma occurring at an early stage in development. Moreover, it is shown how the potential of the archetype or image schema, linked to the somatic-affective early experiences encoded as implicit memories, can be recovered, when Embodied Active Imagination is included in the analytic work. The patient's bodily gestures and somatic experience may bridge the gap between the preverbal-implicit knowledge and the emergence of emotions and images that allow for the creation of a new symbolic narrative.     

Playing to their strengths: Can focusing on typical in-group strengths be detrimental to people of colour?

With increasing awareness about racism, portrayals of communities of colour are shifting away from negative representations. Emphasizing their strengths could counter negative stereotypes about who they are and low expectations for who they can be, but could also backfire. In two experiments centring adolescents (n = 198) and adults of colour (n = 321), the effect of reflecting on a typical strength was moderated by perceived misalignments between racial/ethnic and ideal future selves (i.e., ethnic–ideal self-discrepancy). For participants perceiving them as aligned, reflecting on a typical in-group strength reduced actual–ideal self-discrepancy. However, for participants perceiving them as misaligned, reflecting on a typical in-group strength increased actual–ideal self-discrepancy. Reflecting on a typical strength also indirectly influenced engagement, through actual–ideal self-discrepancy. Reflecting on an atypical in-group strength did not yield significant effects. Thus, emphasizing typical aspects of stigmatized communities, even when positive, sometimes impede identity and motivation.     

从疫情控制看中庸行动我的应急灵活性

本文撰写的目的是,藉助分析COVID-19疫情控制的应急心理机制,提出一个思考中国人“自我”的新架构,希望未来它能成为研究这一热门研究领域的新进路。沿用中国传统流传下来、但却一直被沿用至今的中庸思维,以及其内涵的“阴阳思维”及“全息思维”作为立论基础,提出“中庸行动我”的构念。它是指个体在选择及执行解决问题之具体行动方案时,依现实“情境需求”,灵活地“协调”出一个最恰当的“行动我”,以配合集体战疫的需要及功效。“中庸行动我”这一构念的提出,不仅只是为了解释战疫的成效,更重要的是它欲反映出中国人思维“灵活性”的根源,从而可以作为研究“中国人自我”的另类进路,不再只是以跨文化研究进路所关注的“本质自我”为主要立论基础,从而丰富了该领域现有的知识内涵。

Ten principles of counselling: Grounded theory in a mixed methods research project

This grounded theory (GT) study is part of an extensive mixed methods research project to develop general principles for counselling. Nine hundred counselling protocols were examined. The material is characterised by a quantitative amount of data with a qualitative character. The research is based on the systemic-constructivist research paradigm. The variety of perspectives is an important aspect of the work. Therefore, it is important that the entire research process with GT takes place in exchange with other research settings in order to minimise the limitations caused by the perspective of the researchers. During the research process, there was an intensive examination of GT in order to adapt it to the research project. By using the GT to analyse the extensive qualitative material, the actions of the counsellors were observed and 10 counselling principles were developed. This article presents the research process and the findings.     

“Being human”: A grounded theory approach to exploring how trainers on clinical psychology doctorate programmes decide whether or not to disclose personal experiences of psychological distress to clinical psychology doctorate trainees

Objective

Recent research and guidelines recommend that trainers on clinical psychology doctorate training programmes consider disclosing personal experiences of psychological distress to trainees. Disclosure is thought to promote cultures of openness, validate and normalise trainee distress, encourage trainee disclosure and help-seeking and challenge stigmatising narratives. However, little is known about how trainers decide whether, what or how to disclose. This study aims to address that gap by exploring the processes and factors involved in trainers deciding whether or not to disclose personal experiences of psychological distress to trainees, generating findings of relevance across counselling, psychotherapy and psychology training courses.

Methods

In-depth interviews were conducted with nine trainers on UK clinical psychology doctorate programmes from around the country and analysed in accordance with constructivist grounded theory methods.

Results

Findings indicated that participants valued disclosure personally and professionally but were wary of the dangers of disclosure. Disclosure decisions were made by judging the context against internally held criteria. If criteria were not met, then disclosures were not made. Outcomes, whether positive or negative, served to reinforce the value of disclosure and the importance of managing risks, creating a positive feedback loop.

Conclusions

The findings of this study suggest factors that are important for trainers to consider when deciding whether or not to disclose. The six-factor framework developed may be useful for trainers to consider within reflective practice, supervision or during guided self-reflection in order to make safe, helpful and ethical decisions.
