Laypeople's Risky Decisions In The Climate Change Context: Climate Engineering As A Risk-Defusing Strategy?, Dorothee Amelung, Joachim Funke Dec 2014

Laypeople's Risky Decisions In The Climate Change Context: Climate Engineering As A Risk-Defusing Strategy?, Dorothee Amelung, Joachim Funke

Joachim Funke

This study explores the development of laypeople’s preferences for newly emerg- ing climate engineering technology (CE). It examines whether laypeople perceive CE to be an acceptable back-up strategy (plan B) if current efforts to mitigate CO2 emissions were to fail. This idea is a common justification for CE research in the scientific debate andmay significantly influence future public debates. Ninety-eight German participants chose their preferred climate policy strategy in a quasi-realistic scenario. Participants could chose between mitigation and three CE techniques as alternative options.We employed a think-aloud interview technique, which allowed us to trace participants’ informational needs and thought processes. …


Systems Factorial Technology With R, Joseph W. Houpt, Leslie M. Blaha, John P. Mcintire, Paul R. Havig, James T. Townsend Jan 2013

Systems Factorial Technology With R, Joseph W. Houpt, Leslie M. Blaha, John P. Mcintire, Paul R. Havig, James T. Townsend

Joseph W. Houpt

Systems Factorial Technology (SFT) comprises a set of powerful nonparametric models and measures, together with a theory-driven experiment methodology termed the Double Factorial Paradigm (DFP), for assessing the cognitive information processing mechanisms supporting the processing of multiple sources of information in a given task. We provide an overview of the model-based measures of SFT together with a tutorial on designing a DFP experiment to take advantage of all SFT measures in a single experiment. Illustrative examples are given to highlight the breadth of applicability of these techniques across psychology. We further introduce and demonstrate a new package for performing SFT …

Dealing With The Uncertainties Of Climate Engineering: Warnings From A Psychological Complex Problem Solving Perspective, Dorothee Amelung, Joachim Funke Dec 2012

Dealing With The Uncertainties Of Climate Engineering: Warnings From A Psychological Complex Problem Solving Perspective, Dorothee Amelung, Joachim Funke

Joachim Funke

Decision-makers in the context of climate politics are confronted with considerable uncertainties due to the complexities inherent in the relevant natural and social systems. Nonetheless, pressure on decision-makers to find solutions to dangerous climate change is rising due to the inertia in the climate system. Considering these pressures, technological options (climate engineering) have been proposed to counteract the effects of climatic change. However, introducing options that bear their own scientific uncertainties means further adding to the complexity of the situation. By adopting the psychological perspective of complex problem solving research, we analyze one frequently neglected source of uncertainty with regard …


Scientific Computing For The Cognitive Sciences, Sebastian Sager, Katja Mombaur, Joachim Funke Dec 2012

Scientific Computing For The Cognitive Sciences, Sebastian Sager, Katja Mombaur, Joachim Funke

Joachim Funke

The methodology of Scientific Computing is widely regarded as the third pillar of science, complementary to experiment and theory. While it triggered countless breakthroughs and innovations in technology, engineering, and the natural sciences, a combination with cognitive sciences is yet a rather young field full of opportunities. This special issue is meant to stimulate interdisciplinary research in the Cognitive Sciences, based on state-of-the-art methods


Capacity Coefficient Variations, Joseph W. Houpt, Andrew Heathcote, Ami Eidels, Nathan Medeiros-Ward, Jason Watson, David Strayer Nov 2012

Capacity Coefficient Variations, Joseph W. Houpt, Andrew Heathcote, Ami Eidels, Nathan Medeiros-Ward, Jason Watson, David Strayer

Joseph W. Houpt

The capacity coefficient has become an increasingly popular measure of efficiency under changes in workload. It has been used in applications ranging from psychophysical detection tasks to complex cognitive tasks, as well as in addressing questions in social and clinical psychology. The basic formulation compares response times to each stimulus property (or task) in isolation to response times with all stimulus properties (or tasks) at the same time. A number of variations on the basic capacity coefficient have been used, both in the experimental design and in the calculations, and many more are possible. Here we outline the theoretical reasons …

Mindscapes And Landscapes: Hayek And Simon On Cognitive Extension, Leslie Marsh Oct 2012

Mindscapes And Landscapes: Hayek And Simon On Cognitive Extension, Leslie Marsh

Leslie Marsh

Hayek’s and Simon’s social externalism runs on a shared presupposition: mind is constrained in its computational capacity to detect, harvest, and assimilate “data” generated by the infinitely fine-grained and perpetually dynamic characteristic of experience in complex social environments. For Hayek, mind and sociality are co-evolved spontaneous orders, allowing little or no prospect of comprehensive explanation, trapped in a hermeneutically sealed, i.e. inescapably context bound, eco-system. For Simon, it is the simplicity of mind that is the bottleneck, overwhelmed by the ambient complexity of the environmental. Since on Simon’s account complexity is unidirectional, Simon is far more ebullient about the prospects …


Bayesian Approaches To Assessing Architecture And Stopping Rule, Joseph W. Houpt, A. Heathcote, A. Eidels, J. T. Townsend Jul 2012

Bayesian Approaches To Assessing Architecture And Stopping Rule, Joseph W. Houpt, A. Heathcote, A. Eidels, J. T. Townsend

Joseph W. Houpt

Much of scientific psychology and cognitive science can be viewed as a search to understand the mechanisms and dynamics of perception, thought and action. Two processing attributes of particular interest to psychologists are the architecture, or temporal relationships between sub-processes of the system, and the stopping rule, which dictates how many of the sub-processes must be completed for the system to finish. The Survivor Interaction Contrast (SIC) is a powerful tool for assessing the architecture and stopping rule of a mental process model. Thus far, statistical analysis of the SIC has been limited to null-hypothesis- significance tests. In this talk …


A Decomposition Approach For A New Test-Scenario In Complex Problem Solving, Michael Engelhart, Joachim Funke, Sebastian Sager Jun 2012

A Decomposition Approach For A New Test-Scenario In Complex Problem Solving, Michael Engelhart, Joachim Funke, Sebastian Sager

Joachim Funke

Over the last years, psychological research has increasingly used computer-supported tests, especially in the analysis of complex human decision making and problem solving. The approach is to use computer-based test scenarios and to evaluate the performance of participants and correlate it to certain attributes, such as the participant's capacity to regulate emotions. However, two important questions can only be answered with the help of modern optimization methodology. The first one considers an analysis of the exact situations and decisions that led to a bad or good overall performance of test persons. The second important question concerns performance, as the choices …


General Recognition Theory Extended To Include Response Times: Predictions For A Class Of Parallel Systems, James T. Townsend, Joseph W. Houpt, Noah H. Silbert Jan 2012

General Recognition Theory Extended To Include Response Times: Predictions For A Class Of Parallel Systems, James T. Townsend, Joseph W. Houpt, Noah H. Silbert

Joseph W. Houpt

General Recognition Theory (GRT; Ashby & Townsend, 1986) is a multidimensional theory of classification. Originally developed to study various types of perceptual independence, it has also been widely employed in diverse cognitive venues, such as categorization. The initial theory and applications have been static, that is, lacking a time variable and focusing on patterns of responses, such as confusion matrices. Ashby proposed a parallel, dynamic stochastic version of GRT with application to perceptual independence based on discrete linear systems theory with imposed noise \citep{Ash89}. The current study again focuses on cognitive/perceptual independence within an identification classification paradigm. We extend stochastic …

An Extension Of Sic Predictions To The Wiener Coactive Model, Joseph W. Houpt, James T. Townsend Jun 2011

An Extension Of Sic Predictions To The Wiener Coactive Model, Joseph W. Houpt, James T. Townsend

Joseph W. Houpt

The survivor interaction contrasts (SIC) is a powerful measure for distinguishing among candidate models of human information processing. One class of models to which SIC analysis can apply are the coactive, or channel summation, models of human information processing. In general, parametric forms of coactive models assume that responses are made based on the first passage time across a fixed threshold of a sum of stochastic processes. Previous work has shown that the SIC for a coactive model based on the sum of Poisson processes has a distinctive down--up--down form, with an early negative region that is smaller than the …

Nice Guys Finish Fast And Bad Guys Finish Last: Facilitatory Vs. Inhibitory Interaction In Parallel Systems, Ami Eidels, Joseph W. Houpt, Nicholas Altieri, Lei Pei, James T. Townsend

Joseph W. Houpt

Systems Factorial Technology is a powerful framework for investigating the fundamental properties of human information processing such as architecture (i.e., serial or parallel processing) and capacity (how processing efficiency is affected by increased workload). The Survivor Interaction Contrast (SIC) and the Capacity Coefficient are effective measures in determining these underlying properties, based on response-time data. Each of the different architectures, under the assumption of independent processing, predicts a specific form of the SIC along with some range of capacity. In this study, we explored SIC predictions of discrete-state (Markov process) and continuous-state (Linear Dynamic) models that allow for certain types …


Hayek's Philosophical Psychology, Leslie Marsh Dec 2010

Hayek's Philosophical Psychology, Leslie Marsh

Leslie Marsh

Hayek's philosophical psychology as set out in his The Sensory Order (1952) has, for the most part, been neglected. Despite being lauded by computer scientist grandee Frank Rosenblatt and by Nobel prize-winning biologist Gerald Edelman, cognitive scientists -- with a few exceptions -- have yet to discover Hayek's philosophical psychology. On the other hand, social theorists, Hayek's traditional disciplinary constituency, have only recently begun to take note and examine the importance of psychology in the complete Hayek corpus. This volume brings together for the first time state-of-the-art contributions from neuroscientists and philosophers of mind as well as economists and social …
