Counter‐Interrogation Strategies when Anticipating Questions on Intentions

The present experimental study adds to the emerging line of psycholegal research focusing on true and false intentions. It is the first to examine mock suspects' (N = 120) counter‐interrogation strategies in investigative interviews in which they anticipate questions on their intentions. As planning is an inherent part of many intentions, mock suspects were, in addition to questions on their intentions, asked a set of questions that pertained to the planning phase in which they formed their intentions. Besides ratings of the anticipation and difficulty of the questions, participants were asked to provide their principal strategy for being perceived as truthful. Both truth tellers and liars perceived the questions on the planning phase as significantly more unanticipated than the questions on their intentions. Furthermore, liars perceived the questions on the planning phase as more difficult to answer than did truth tellers. Liars and truth tellers differed with respect to their principal strategy employed for being perceived as truthful. Liars' most commonly used strategy was to stick to the cover story, whereas truth tellers' most common strategy was to be honest. The results are discussed in relation to the unanticipated questions approach and psychological concepts such as the illusion of transparency. Copyright © 2012 John Wiley & Sons, Ltd.     

The effect of exposure duration on visual character identification in single, whole, and partial report

The psychometric function of single-letter identification is typically described as a function of stimulus intensity. However, the effect of stimulus exposure duration on letter identification remains poorly described. This is surprising because the effect of exposure duration has played a central role in modeling performance in whole and partial report (Shibuya & Bundesen, 1988). Therefore, we experimentally investigated visual letter identification as a function of exposure duration. We compared the exponential, the gamma, and the Weibull psychometric functions, all with a temporal offset included, as well as the ex-Gaussian, the log-logistic, and finally the squared-logistic, which is a psychometric function that to our knowledge has not been described before. The log-logistic and the squared-logistic psychometric function fit well to experimental data. Also, we conducted an experiment to test the ability of the psychometric functions to fit single-letter identification data, at different stimulus contrast levels; also here the same psychometric functions prevailed. Finally, after insertion into Bundesen's Theory of Visual Attention (Bundesen, 1990), the same psychometric functions enable closer fits to data from a previous whole and partial report experiment.     

Measuring and modeling attentional dwell time

Attentional dwell time (AD) defines our inability to perceive spatially separate events when they occur in rapid succession. In the standard AD paradigm, subjects should identify two target stimuli presented briefly at different peripheral locations with a varied stimulus onset asynchrony (SOA). The AD effect is seen as a long-lasting impediment in reporting the second target, culminating at SOAs of 200?C500?ms. Here, we present the first quantitative computational model of the effect??a theory of temporal visual attention. The model is based on the neural theory of visual attention (Bundesen, Habekost, & Kyllingsb?k, Psychological Review, 112, 291?C328 2005) and introduces the novel assumption that a stimulus retained in visual short-term memory takes up visual processing-resources used to encode stimuli into memory. Resources are thus locked and cannot process subsequent stimuli until the stimulus in memory has been recoded, which explains the long-lasting AD effect. The model is used to explain results from two experiments providing detailed individual data from both a standard AD paradigm and an extension with varied exposure duration of the target stimuli. Finally, we discuss new predictions by the model.     

“Imma march’ toward Ka’ba”: Islam in Swedish hip-hop

The common history of Islam and the hip-hop culture can be traced back to the early expression of the culture. Since the early days of hip-hop, Muslims have used hip-hop to convey Islamic messages. Artists driven, in equal parts, by a strong personal belief in Islam and a love for hip-hop music have taken Islamic-themed hip-hop outside its country of birth, the U.S., and have made it into a matter of global concern. In an attempt to contribute to and, hopefully, complicate the picture of what has been called the transglobal hip-hop umma, this article explores how Swedish Muslims articulate their beliefs through hip-hop in Sweden. With examples from both the Swedish mainstream and the underground, it highlights hip-hop music with an Islamic engagement whose aim is to promote and perform what is understood as ??Islamic values,?? such as ethics, peace, social responsibility, and a strong personal belief.     

The Role of Conditional Likelihoods in Latent Variable Modeling

Psychometrika - In psychometrics, the canonical use of conditional likelihoods is for the Rasch model in measurement. Whilst not disputing the utility of conditional likelihoods in measurement, we...     

Has Plantinga “buried” Mackie’s logical argument from evil?

In seeking to undermine Mackie’s logical argument from evil, Plantinga assumes that Mackie’s argument regards it as a necessary truth that a wholly good God would eliminate all evil that he could eliminate. I argue that this is an interpretative mistake, and that Mackie is merely assuming that the theist believes that God’s goodness entails that God would eliminate all evil that he could eliminate. Once the difference between these two assumptions, and the implausibility of Plantinga’s assumption, are brought out, Plantinga’s celebrated critique of Mackie’s argument can be seen to be far less compelling than is often assumed to be the case.     

How to Gain the Benefits of the Expert Performance Approach in Domains Where the Correctness of Decisions are Not Readily Available: A Reply to Weiss and Shanteau

Weiss and Shanteau criticize the expert‐performance approach and argue that this approach has not, and most importantly, cannot be applied to the study of ‘experts’ in domains that lack readily available objective measures of performance, such as accuracy of judgments. In this response, I demonstrate that it is not necessary to use fictitious stimuli for the judgments, for which no correct responses can be identified, and where only their Cochrane, Weiss, and Shanteau index can be calculated. Instead, the expert performance approach regenerates the judgment situation for actual cases and tracks down their subsequent observed real‐world outcomes. Participants' judgments of the stimuli can then be directly scored against the actual outcomes. Opportunities for training and deliberate practice are discussed.
