Abstract

At the core of the many debates throughout cognitive science concerning how decisions are made are the processes governing the time course of preference formation and decision. From perceptual choices, such as whether the signal on a radar screen indicates an enemy missile or a spot on a CT scan indicates a tumor, to cognitive value-based decisions, such as selecting an agreeable flatmate or deciding the guilt of a defendant, significant and everyday decisions are dynamic over time. Phenomena such as decoy effects, preference reversals and order effects are still puzzling researchers. For example, in a legal context, jurors receive discrete pieces of evidence in sequence, and must integrate these pieces together to reach a singular verdict. From a standard Bayesian viewpoint the order in which people receive the evidence should not influence their final decision, and yet order effects seem a robust empirical phenomena in many decision contexts. Current research on how decisions unfold, especially in a dynamic environment, is advancing our theoretical understanding of decision making. This Research Topic aims to review and further explore the time course of a decision - from how prior beliefs are formed to how those beliefs are used and updated over time, towards the formation of preferences and choices and post-decision processes and effects. Research literatures encompassing varied approaches to the time-scale of decisions will be brought into scope: a) Speeded decisions (and post-decision processes) that require the accumulation of noisy and possibly non-stationary perceptual evidence (e.g., randomly moving dots stimuli), within a few seconds, with or without temporal uncertainty. b) Temporally-extended, value-based decisions that integrate feedback values (e.g., gambling machines) and internally-generated decision criteria (e.g., when one switches attention, selectively, between the various aspects of several choice alternatives). c) Temporally extended, belief-based decisions that build on the integration of evidence, which interacts with the decision maker's belief system, towards the updating of the beliefs and the formation of judgments and preferences (as in the legal context). Research that emphasizes theoretical concerns (including optimality analysis) and mechanisms underlying the decision process, both neural and cognitive, is presented, as well as research that combines experimental and computational levels of analysis.

Abstract

Complex problem solving (CPS) and related topics such as dynamic decision-making (DDM) and complex dynamic control (CDC) represent multifaceted psychological phenomena. In abroad sense, CPS encompasses learning, decision-making, and acting in complex and dynamic situations. Moreover, solutions to problems that people face in such situations are often generated in teams or groups. This adds another layer of complexity to the situation itself because of the emerging issues that arise from the social dynamics of group interactions. This framing of CPS means that it is not a single construct that can be measured by using a particular type of CPS task (e.g. minimal complex system tests), which is a view taken by the psychometric community. The proposed approach taken here is that because CPS is multifaceted, multiple approaches need to be taken to fully capture and understand what it is and how the different cognitive processes associated with it complement each other.Thus, this Research Topic is aimed at showcasing the latest work in the fields of CPS, as well as DDM and CDC that takes a holist approach to investigating and theorizing about these abilities. The collection of articles encompasses conceptual approaches as well as experimental and correlational studies involving established or new tools to examine CPS, DDM and CDC. This work contributes to answering questions about what strategies and what general knowledge can be transferred from one type of complex and dynamic situation to another, what learning conditions result in transferable knowledge and skills, and how these features can be trained.

Abstract

In 2003, Rachel A. Volberg wrote: “Why is it that gambling is not even on the radar when we consider the array of risks that adolescents must confront as they move towards adulthood?” Nowadays, after thirteen years, although much more is known about this particular form of risk behavior, there is still a general tendency, at least among laypersons, to not perceive gambling as a potential danger for youth and other population segments (e.g., individuals with migration background, seniors, sports professionals). However, the latest edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5, American Psychological Association, 2013) included Gambling Disorder as the only condition in the Section Non-Substance-Related Disorders. Moreover, it is specified that the disorder can indeed occur in adolescence or young adulthood. Despite this fact, theoretical and applied research on problem gambling with regard to adolescence and other risk groups is still in its infancy.For this reason, it seems to be important to organize a Research Topic on gambling in Frontiers in Psychology in order to i) highlight the necessity of considering gambling as a potential harmful activity; ii) summarize the state-of-art of international research on different aspects of the topic; and iii) offer important novel findings relevant for advancing knowledge in the field of gambling. Different types of research articles will be provided including original articles, systematic/scoping reviews, meta-analyses, case reports, and commentaries. These contributions will be focused on the following most important areas in gambling research: Measurement (Which are the most widely used instruments to assess gambling-related problems as well as proximate constructs and what are their psychometric properties? Are there new instruments to detect adolescent problem gamblers?), Protective and risk factors (What do we know about ecological and individual influences on gambling behavior? Which factors affect problem gambling most and in which way?), Prevention (Which are the most promising prevention programs implemented until now? Which are necessary ingredients for effective prevention?), Treatment (When individuals seek help for their gambling-related problems, which are the clinical treatments that are offered? Do we have evidence for treatment effectiveness for different subgroups?).To try to fulfill this goal in the most comprehensive way, researchers from different countries and with specific competencies and interests will be contacted and encouraged to submit a contribution. Through the integration of international and multidisciplinary contributions, i) new challenges in the field of gambling will be identified (e.g., definition of specific at-risk groups, specification of effective interventions in terms of best practices) and ii) new research routes (e.g., the use of behavioral data) will be outlined in order to build a comprehensive understanding of problem gambling. The overall aim is to summarize the state of art, to propose original novel findings, and to outline new directions in gambling research.

Abstract

This volume describes and explains the educational method of Case-Based Clinical Reasoning (CBCR) used successfully in medical schools to prepare students to think like doctors before they enter the clinical arena and become engaged in patient care. Although this approach poses the paradoxical problem of a lack of clinical experience that is so essential for building proficiency in clinical reasoning, CBCR is built on the premise that solving clinical problems involves the ability to reason about disease processes. This requires knowledge of anatomy and the working and pathology of organ systems, as well as the ability to regard patient problems as patterns and compare them with instances of illness scripts of patients the clinician has seen in the past and stored in memory. CBCR stimulates the development of early, rudimentary illness scripts through elaboration and systematic discussion of the courses of action from the initial presentation of the patient to the final steps of clinical management.The book combines general backgrounds of clinical reasoning education and assessment with a detailed elaboration of the CBCR method for application in any medical curriculum, either as a mandatory or as an elective course. It consists of three parts: a general introduction to clinical reasoning education, application of the CBCR method, and cases that can used by educators to try out this method.

Abstract

In the study of human thinking, two main research questions can be asked: “Descriptive Q: What is human thinking like? Normative Q: What ought human thinking be like?” For decades, these two questions have dominated the field, and the relationship between them generated many a controversy. Empirical normativist approaches regard the answers to these questions as positively correlated – in essence, human thinking is what it ought to be (although what counts as the ‘ought’ standard is moot). In contemporary theories of reasoning and decision making, this is often associated with a Panglossian framework, an adaptationist approach which regards human thinking as a priori rational. In contrast, prescriptive normativism sees the answers to these two questions as negatively correlated. Normative models are still relevant to human thought, but human behaviour deviates from them quite markedly (with the invited conclusion that humans are often irrational). Prescriptive normativism often results in a Meliorist agenda, which sees rationality as amenable to education. Both empirical and prescriptive normativism can be contrasted with a descriptivist framework for psychology of human thinking. Following Hume’s strict divide between the ‘is’ and the ‘ought’, descriptivism regards the descriptive and normative research questions as uncorrelated, or dissociated, with only the former question suitable for psychological study of human behaviour. This basic division carries over to the relation between normative (‘ought’) rationality, based on conforming to normative standards; and instrumental (‘is’) rationality, based on achieving one’s goals. Descriptivist approaches regard the two as dissociated, whereas normativist approaches tend to see them as closely linked, with normative arguments defining and justifying instrumental rationality. This research topic brings together diverse contributions to the continuing debate. Featuring contributions from leading researchers in the field, the e-book covers a wide range of subjects, arranged by six sections: The standard picture: Normativist perspectivesIn defence of soft normativismExploring normative modelsDescriptivist perspectivesEvolutionary and ecological accountsEmpirical reports With a total of some 24 articles from 55 authors, this comprehensive treatment includes theoretical analyses, meta-theoretical critiques, commentaries, and a range of empirical reports. The contents of the Research Topic should appeal to psychologists, linguists, philosophers and cognitive scientists, with research interests in a wide range of domains, from language, through reasoning, judgment and decision making, and moral judgment, to epistemology and theory of mind, philosophical logic, and meta-ethics.
