Dual-process theories of reasoning: Contemporary issues and developmental applications

In this paper, I discuss the current state of theorising about dual processes in adult performance on reasoning and decision making tasks, in which Type 1 intuitive processing is distinguished from Type 2 reflective thinking. I show that there are many types of theory some of which distinguish modes rather than types of thinking and that assumptions about underlying cognitive architecture vary. I show that some dual-system theories have been replaced recently by the idea that we have two or more distinct ‘minds’ with different evolutionary histories. I also present the most recent formulation of my own account of dual processing within hypothetical thinking theory, at a level more easily applied to performance on specific tasks. I then consider implications for cognitive development, pointing out that while Type 2 thinking is clearly linked to the development of cognitive ability, it combines and competes with multiple Type 1 processing systems which persist in adult cognition, each of which could have their own developmental time course. Hence, while dual-process theories can and should inspire much research and theory in cognitive development, the derivation of predictions for cognitive development is far from straightforward.     

The High Cost of Complexity in Experimental Design and Data Analysis: Type I and Type II Error Rates in Multiway ANOVA

The availability of statistical software packages has led to a sharp increase in use of complex research designs and complex statistical analyses in communication research. An informal examination of studies from 2 leading communication journals suggests that the analysis of variance (ANOVA) is often the statistic of choice, and a substantial proportion of published research reports using ANOVA employ complex (k ≥ 3) factorial designs, often involving multiple dependent variables. This article reports a series of Monte Carlo simulations which demonstrate that this complexity may come at a heavier cost than many communication researchers realize. As frequently used, complex factorial ANOVA yield Type I and Type II error rates that many communication scholars would likely consider unacceptable. Consequently, quality of statistical inference in many studies is highly suspect. Communication researchers are warned about problems associated with design and statistical complexity and solutions are suggested.     

Defining Nano,Nanotechnology and Nanomedicine: Why Should It Matter?

Nanotechnology, which involves manipulation of matter on a ‘nano’ scale, is considered to be a key enabling technology. Medical applications of nanotechnology (commonly known as nanomedicine) are expected to significantly improve disease diagnostic and therapeutic modalities and subsequently reduce health care costs. However, there is no consensus on the definition of nanotechnology or nanomedicine, and this stems from the underlying debate on defining ‘nano’. This paper aims to present the diversity in the definition of nanomedicine and its impact on the translation of basic science research in nanotechnology into clinical applications. We present the insights obtained from exploratory qualitative interviews with 46 stakeholders involved in translational nanomedicine from Europe and North America. The definition of nanomedicine has implications for many aspects of translational research including: fund allocation, patents, drug regulatory review processes and approvals, ethical review processes, clinical trials and public acceptance. Given the interdisciplinary nature of the field and common interest in developing effective clinical applications, it is important to have honest and transparent communication about nanomedicine, its benefits and potential harm. A clear and consistent definition of nanomedicine would significantly facilitate trust among various stakeholders including the general public while minimizing the risk of miscommunication and undue fear of nanotechnology and nanomedicine.     

Bridging Science and Religion: How Health‐Care Workers as Storytellers Construct Spiritual Meanings

Contrary to the notion that medical science has supplanted religious understandings of human suffering, recent research suggests that health‐care workers like nurses can still portray their confrontations with illness and death in spiritual terms through storytelling. However, scholars have yet to systematically analyze the rhetorical devices used to construct spiritual meanings. Drawing on a symbolic interactionist perspective, we theorize that front‐line health professionals can deploy various rhetorical devices to infuse their workplace interactions with a spiritual significance. We also propose novel fuzzy set analysis techniques for determining which configurations of devices are most important in developing spiritual meanings. This approach was illustrated by examining 173 stories elicited from nurses at a nonsectarian, teaching hospital about encounters at work that significantly impacted their understanding of spirituality. Consistent with our expectations, the way in which nurses tell stories about their experiences not only shapes whether they attach spiritual significance to them, but whether they perceive spirituality and medicine to be compatible. We discuss the implications of our findings for future research on lived religion, conflicting identities, and institutional boundaries.     

We favor formal models of heuristics rather than lists of loose dichotomies: a reply to Evans and Over

In their comment on Marewski et al. (good judgments do not require complex cognition, 2009) Evans and Over (heuristic thinking and human intelligence: a commentary on Marewski, Gaissmaier and Gigerenzer, 2009) conjectured that heuristics can often lead to biases and are not error free. This is a most surprising critique. The computational models of heuristics we have tested allow for quantitative predictions of how many errors a given heuristic will make, and we and others have measured the amount of error by analysis, computer simulation, and experiment. This is clear progress over simply giving heuristics labels, such as availability, that do not allow for quantitative comparisons of errors. Evans and Over argue that the reason people rely on heuristics is the accuracy-effort trade-off. However, the comparison between heuristics and more effortful strategies, such as multiple regression, has shown that there are many situations in which a heuristic is more accurate with less effort. Finally, we do not see how the fast and frugal heuristics program could benefit from a dual-process framework unless the dual-process framework is made more precise. Instead, the dual-process framework could benefit if its two “black boxes” (Type 1 and Type 2 processes) were substituted by computational models of both heuristics and other processes.     

‘Categories We Share’: Mobilising Common In‐groups in Discourse on Contemporary Immigration in Greece

Prejudice reduction has been an important concern within social psychology both in theory and applied research. According to the premises of Social Identity Theory, redrawing of the category boundaries is often considered a necessary step in order to battle prejudice, because in‐group favouritism when the category boundaries change is diffused to the previously distinct identities. The present paper offers a review of the relevant research, and following a discourse analytic perspective argues that recategorisation can also be viewed as a rhetorical resource that people use in verbal interaction in order to achieve certain rhetorical ends. This point is exemplified using interview data from Greece with Greek participants who mobilise common in‐groups between themselves and the immigrants in Greece. Different common in‐groups were mobilised on the basis of common human nature, common ethnic descent and through the use of the common experience of migration that many Greek people have because Greece has been an emigrant sending country for the biggest part of the 20th century. Occasionally, these category constructions were used to differentiate between immigrants of different ethnic descent claiming that only certain immigrant groups can integrate to Greek society, whereas on other instances, these common in‐groups were used in order to inoculate speakers of accusations of prejudice.

The persistence of underpowered studies in psychological research: causes, consequences, and remedies

Underpowered studies persist in the psychological literature. This article examines reasons for their persistence and the effects on efforts to create a cumulative science. The "curse of multiplicities" plays a central role in the presentation. Most psychologists realize that testing multiple hypotheses in a single study affects the Type I error rate, but corresponding implications for power have largely been ignored. The presence of multiple hypothesis tests leads to 3 different conceptualizations of power. Implications of these 3 conceptualizations are discussed from the perspective of the individual researcher and from the perspective of developing a coherent literature. Supplementing significance tests with effect size measures and confidence intervals is shown to address some but not necessarily all problems associated with multiple testing.

Anger in type a women: Implications for coronary heart disease

The present study examines the relationship between Type A behaviour and anger in a sample of managerial women. The Type A behaviour pattern is hard driving, job-devoted lifestyle which is associated with a significantly increased risk of coronary heart disease in men as in women. Anger and hostility have been reported to be critical components of the Type A behaviour pattern which contribute to coronary heart disease. This research also examines the relationship between occupational demands and job anger in managerial women. Occupational demands include demands particularly unique to women in non-traditional occupational roles such as inequity of pay, underutilization of skills, low boss support and perceived sex discrimination. State (job) and Trait Anger were also assessed as were various psychological and behavioural outcomes such as state anxiety, depression, job satisfaction, absenteeism, and “intention to turnover”. Results showed that sex discrimination was a significant occupational stressor in Type As only. Further results of a multiple regression analysis indicated tha for Type As only, sex discrimination was positively associated with job anger when social support from one's boss was low. However, with increasing support, Type As were less likely to report anger when discrimination was high. In conclusion, the results of this study have demonstrated that social support can function as a buffer against anger, thus extending the buffering hypothesis originally put forth to refer to the buffering effects of social support and anxiety.     

Honouring our great grandparents: towards a rhetorical analysis of family therapy

This paper argues that family therapy is an inherently and inescapably rhetorical activity, although its connections with rhetoric have remained largely ignored and the implications for practice unexplored. An uncritical acceptance of a range of postmodern ideas has led many family therapists to ignore the power of their therapeutic rhetoric. The paper offers rhetorical analysis as a tool to help family therapists to reflect on the rhetorical power of their practice and thereby to exercise this power more responsibly.     

The Virtues of Evidence

Evidence-based medicine has been defined as the conscientious and judicious use of current best evidence in making clinical decisions. This paper will attempt to explicate the terms "conscientious" and "judicious" within the evidence-based medicine definition. It will be argued that "conscientious" and "judicious" represent virtue terms derived from virtue ethics and virtue epistemology. The identification of explicit virtue components in the definition and therefore conception of evidence-based medicine presents an important starting point in the connection between virtue theories and medicine itself. In addition, a unification of virtue theories and evidence-based medicine will illustrate the need for future research in order to combine the fields of virtue-based approaches and clinical practice.     

The ethos and ethics of translational research

Calls for the "translation" of research from bench to bedside are increasingly demanding. What is translation, and why does it matter? We sketch the recent history of outcome-oriented translational research in the United States, with a particular focus on the Roadmap Initiative of the National Institutes of Health (Bethesda, MD). Our main example of contemporary translational research is stem cell research, which has superseded genomics as the translational object of choice. We explore the nature of and obstacles to translational research and assess the ethical and biomedical challenges of embracing a translational ethos.     

Translational research in behavior analysis: historical traditions and imperative for the future

"Pure basic" science can become detached from the natural world that it is supposed to explain. "Pure applied" work can become detached from fundamental processes that shape the world it is supposed to improve. Neither demands the intellectual support of a broad scholarly community or the material support of society. Translational research can do better by seeking innovation in theory or practice through the synthesis of basic and applied questions, literatures, and methods. Although translational thinking has always occurred in behavior analysis, progress often has been constrained by a functional separation of basic and applied communities. A review of translational traditions in behavior analysis suggests that innovation is most likely when individuals with basic and applied expertise collaborate. Such innovation may have to accelerate for behavior analysis to be taken seriously as a general-purpose science of behavior. We discuss the need for better coordination between the basic and applied sectors, and argue that such coordination compromises neither while benefiting both.     

Incorporation of a successful community-based mammography intervention: dissemination beyond a community trial.

Although a variety of interventions to increase breast cancer screening have been found to be effective in community-based trials, their ultimate contribution depends on the extent to which they are incorporated (i.e., adopted and adapted) by community organizations. From 1990 to 1995, the authors conducted a National Cancer Institute-funded community-based trial that increased screening mammography among women ages 40 and older living in Minneapolis public housing. This study describes the processes by which this intervention, called Friend to Friend, was successfully adopted by the American Cancer Society, Midwest Division, and adapted for use by women throughout the state. The authors offer insights from experience with this translational effort and make recommendations to facilitate collaboration between research and community organizations.     

Can we measure out a life in coffee spoons?

Public policy decisions in medicine and other fields necessitate careful weighing of choices and consequences. Cost-benefit analyses have been offered as one way to facilitate such decisions. In "Quantifying the value of human life," L. Eugene Arnold asserts that mathematical models such as his offer greater clarity in making public policy decisions than is possible with the "intuitive" or "emotional" approach. In our opinion, problems associated with this quantitative analysis demonstrate a need for caution in applying such mathematical models to public policy decisions....     

The Message Design Logics of Responses to HIV Disclosures

This article uses the theory of message design logics to investigate the relative sophistication of responses to disclosure of HIV status. In Study 1, 548 college students imagined a sibling revealing an HIV‐positive diagnosis. Their responses to the HIV disclosures were coded as expressive (n= 174), conventional (n= 298), or rhetorical (n= 66). Type of message produced was associated with gender and HIV aversion. In Study 2, 459 individuals living with HIV rated response messages that were taken verbatim from Study 1. Expressive messages were rated lowest in quality, and rhetorical messages were rated highest. The discussion focuses on the utility of message design logics for understanding responses to HIV disclosures and the implications for message design logics.     

Malthus's Essay on Population: the facts of "super-growth" and the rhetoric of scientific persuasion

For the Malthusian theory of population to be accepted as "scientific," it was essential that the theory be established on wide empirical evidence. A close examination of the "facts" provided by Malthus, however, shows that many of his crucial facts are based on distortions of the available evidence. Malthus was probably aware of much of this weakness, but for rhetorical reasons he persisted with the sandy empirical foundations from which he began.     

Reengineering Biomedical Translational Research with Engineering Ethics

It is widely accepted that translational research practitioners need to acquire special skills and knowledge that will enable them to anticipate, analyze, and manage a range of ethical issues. While there is a small but growing literature that addresses the ethics of translational research, there is a dearth of scholarship regarding how this might apply to engineers. In this paper we examine engineers as key translators and argue that they are well positioned to ask transformative ethical questions. Asking engineers to both broaden and deepen their consideration of ethics in their work, however, requires a shift in the way ethics is often portrayed and perceived in science and engineering communities. Rather than interpreting ethics as a roadblock to the success of translational research, we suggest that engineers should be encouraged to ask questions about the socio-ethical dimensions of their work. This requires expanding the conceptual framework of engineering beyond its traditional focus on “how” and “what” questions to also include “why” and “who” questions to facilitate the gathering of normative, socially-situated information. Empowering engineers to ask “why” and “who” questions should spur the development of technologies and practices that contribute to improving health outcomes.     

Individual Style of Activity and Adaptation to Standard Performance Requirements

This article introduces American psychologists to some approaches from the former Soviet Union to dealing with training and performance problems derived from indi- vidual differences in personality features. Our work considers some aspects of these problems based on Russian psychologists' study of personality within the framework of the theory of activity. The approach is known as "individual style of activity" and is fundamental to the analysis of practical achievement in Russian psychology. Sev- eral areas of applied research are presented to illustrate the approach. These studies examine the process of adaptation to objective requirements by participants with distinct individual features. This research does not emphasize the classification of individuals into particular groups for the purpose of selection; rather it emphasizes how to facilitate the adaptation of people with diverse personal features through the development of individualized methods of performance, teaching, and training. The findings have many important applications in education, sports, work, and other performance settings.
