This article reports on an effort to explore the differences between two approaches to intuition and expertise that are often viewed as conflicting: heuristics and biases (HB) and naturalistic decision making (NDM). Starting from the obvious fact that professional intuition is sometimes marvelous and sometimes flawed, the authors attempt to map…

Probability theory has long been taken as the self-evident norm against which to evaluate inductive reasoning, and classical demonstrations of violations of this norm include the conjunction error and base-rate neglect. Many of these phenomena require multiplicative probability integration, whereas people seem more inclined to linear additive…

Evaluators face challenges when programs consistently fail to meet expectations for performance or improvement and consequently, evaluators may recommend that closing a program is the most prudent course of action. However, the evaluation literature provides little guidance regarding when an evaluator might recommend program closure. Given…

According to A. Bandura's (1986) social cognitive theory, individuals form their self-efficacy beliefs by interpreting information from four sources: mastery experience, vicarious experience, social persuasions, and physiological or affective states. The purpose of this study was to examine the heuristics students use as they form their…

Isomorphs of a puzzle called m+m resulted in faster solution times and an easily reproduced solution path in a labeled version of the problem compared to a more difficult binary version. We conjecture that performance is related to a type of heuristic called direction that not only constrains search space in the labeled version, but also…

Midwives in Ghana provide the majority of rural primary and maternal healthcare services, but have limited access to data for decision making and knowledge work. Few mobile health (mHealth) applications have been designed for midwives. The study purpose was to design and test an mHealth application (mClinic) that can improve data access and reduce…

Statistical procedures based on the general linear model (GLM) share much in common with one another, both conceptually and practically. The use of structural equation modeling path diagrams as tools for teaching the GLM as a body of connected statistical procedures is presented. A heuristic data set is used to demonstrate a variety of univariate…

Retrieval monitoring enhances episodic memory accuracy. For instance, false recognition is reduced when participants base their decisions on more distinctive recollections, a retrieval monitoring process called the distinctiveness heuristic. The experiments reported here tested the hypothesis that autobiographical elaboration during study (i.e.,…

Students learn new abstract concepts best when these concepts are connected through a well-designed analogy, to familiar ideas. Since the concept of the relativistic spacetime distance is highly abstract, it would be desirable to connect it to the familiar Euclidean distance, but present the latter in such a way that it makes a transparent contact…

This article situates the preparation of teachers to teach in culturally and linguistically complex classrooms in international contexts. It investigates long-term social and institutional effects of professional development and documents processes that facilitate teachers' continued learning. Data from a decade-long study of U.S. and South…

Purpose: The purpose of this paper is to describe and analyse the implementation by a non-governmental organization (NGO) of an intervention with two different strategies--one employing confrontational approaches, the other cooperative ones--aiming to reduce the rate of successful purchase attempts (PAs) of medium-strength beer in Sweden.…

Implicit measures can be defined as outcomes of measurement procedures that are caused in an automatic manner by psychological attributes. To establish that a measurement outcome is an implicit measure, one should examine (a) whether the outcome is causally produced by the psychological attribute it was designed to measure, (b) the nature of the…

This dissertation reports on a study investigating the identity of first-year university students as writers. The longitudinal project explored how students from educationally disadvantaged backgrounds construct their identities as undergraduates and as academic writers in their first year. The research was qualitative and interpretative, and used…

Scope and Method of Study. This qualitative study used heuristic phenomenology and involved 20 interviews at 3 different sites, 2 focus groups, formal and informal observations, and the analysis of various artifacts including photos, drawings, and documents. Findings and Conclusions. Third culture kids are a diverse group of individuals who spent…

This case study provides an illustration of the heuristic practices of a high-performing research department, which in turn, will help build much needed models applicable in the context of large urban districts. This case study examines the accountability, planning, evaluation, testing, and research functions of a research department in a large…
