Thinking intuitively: the rich (and at times illogical) world of concepts

Intuitive knowledge of the world involves knowing what kinds of things have which properties. We express it in generalities such as “ducks lay eggs”. It contrasts with extensional knowledge about actual individuals in the world, which we express in quantified statements such as “All US Presidents are male”. Reasoning based on this intuitive knowledge, while highly fluent and plausible may in fact lead us into logical fallacy. Several lines of research point to our conceptual memory as the source of this logical failure. We represent concepts with prototypical properties, judging likelihood and argument strength on the basis of similarity between ideas. Evidence that our minds represent the world in this intuitive way can be seen in a range of phenomena, including how people interpret logical connectives applied to everyday concepts, studies of creativity and emergence in conceptual combination, and demonstrations of the logically inconsistent beliefs that people express in their everyday language

'Not Quite Right': Helping Students to Make Better Arguments

This paper looks at the need for a better understanding of the impediments to critical thinking in relation to graduate student work. The paper argues that a distinction is needed between two vectors that influence student writing: (1) the word-level–sentence-level vector; and (2) the grammar–inferencing vector. It is suggested that much of the work being done to assist students is only done on the first vector. This paper suggests a combination of explicit use of deductive syllogistic inferences and computer-aided argument mapping is needed. A methodology is suggested for tackling assignments that require students to ‘make an argument’. It is argued that what lecturers understand tacitly, now needs to be made a focus of deliberate educational practices

Children's Developing Intuitions About the Truth Conditions and Implications of Novel Generics Versus Quantified Statements

Generic statements express generalizations about categories and present a unique semantic profile that is distinct from quantified statements. This paper reports two studies examining the development of children's intuitions about the semantics of generics and how they differ from statements quantified by all, most, and some. Results reveal that, like adults, preschoolers (a) recognize that generics have flexible truth conditions and are capable of representing a wide range of prevalence levels; and (b) interpret novel generics as having near‐universal prevalence implications. Results further show that by age 4, children are beginning to differentiate the meaning of generics and quantified statements; however, even 7‐ to 11‐year‐olds are not adultlike in their intuitions about the meaning of most‐quantified statements. Overall, these studies suggest that by preschool, children interpret generics in much the same way that adults do; however, mastery of the semantics of quantified statements follows a more protracted course.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/111169/1/cogs12176.pd

The Defensive Effect of Medical Practice Policies in Malpractice Litigation

The theoretical prospects for medical practice policies to reform malpractice law by giving conclusive defensive effect to medical custom were studied. A practice policy, however rigorous, is of no use if the nature of the claimed error is either incorrect performance of the treatment in question or failure to recognize the correct practice policy to employ by virtue of a falure in diagnosis

Protection against Government Takings: Compensation for Regulation?

The paper responds to recent debate in New Zealand on the power of the government to take private property, directly or through regulatory constraints. This aspect of regulation has received less attention in New Zealand than it warrants. This paper addresses the issue of which protections against takings are appropriate, and the role of compensation as a protective device. A taking can be broadly defined an act by which a government assumes or assigns control over all or part of a property right held by a private party. Government regulation is typically not treated as a taking. In practice, compensation is normally required only for physical takings, such as the acquisition of land, and is not available for takings through regulation, such as restricting the right to use land in a particular way. New Zealand has three options for improved protection against takings: a tighter regime for scrutinising the quality of regulation, more restricted takings powers, and extended compensation provisions. The desirability and practicality of a greater role for compensation requires, however, more detailed consideration. The paper aims to stimulate further debate in this area as an aspect of the wider debate on regulatory quality.Eminent Domain; Compensation; Regulatory Takings; Police Power; Public Works; Land Use

Online learning in the workplace: a hybrid model of participation in networked, professional learning

The design and conceptualisation of online learning environments for work-related, professional learning was addressed through research with users of an online environment for social workers. The core questions for the research were to identify the nature of participation in the online environment, the relationship between online participation and the offline context, and the implications for conceptualisation of online learning environments to support work-related learning. Key areas of the research literature in technology-enhanced and work related learning are discussed in order to position the study, to inform the research methods used and interpretation of the findings. Online participation needs to be understood as a hybrid concept, in that it is a reflection of offline roles, opportunities and pressures, as well as the usefulness, usability and relevance of what is online. Online participation was diverse, from short browsing for information to more reflective engagement that supported movement across the boundaries between roles and areas of work practice and a focus on practice skills and underlying values. Online sites intended to support work-related learning should start from the perspective of the socio-technical interaction network, with its emphasis on building in the social context at all stages in the life of a site

Strategic I/O Psychology and the Role of Utility Analysis Models

In the 1990’s, the significance of human capital in organizations has been increasing,and measurement issues in human resource management have achieved significant prominence. Yet, I/O psychology research on utility analysis and measurement has actually declined. In this chapter we propose a decision-based framework to review developments in utility analysis research since 1991, and show that through lens of this framework there are many fertile avenues for research. We then show that both I/O psychology and strategic HRM research and practice can be enhanced by greater collaboration and integration, particularly regarding the link between human capital and organizational success. We present an integrative framework as the basis for that integration, and illustrate its implications for future research
