Executive functions in decision making: An individual differences approach

This individual differences study examined the relationships between three executive functions (updating, shifting, and inhibition), measured as latent variables, and performance on two cognitively demanding subtests of the Adult Decision Making Competence battery: Applying Decision Rules and Consistency in Risk Perception. Structural equation modelling showed that executive functions contribute differentially to performance in these two tasks, with Applying Decision Rules being mainly related to inhibition and Consistency in Risk Perception mainly associated to shifting. The results suggest that the successful application of decision rules requires the capacity to selectively focus attention and inhibit irrelevant (or no more relevant) stimuli. They also suggest that consistency in risk perception depends on the ability to shift between judgement contexts.     

Mirror neurons and their function in cognitively understood empathy

The current renewal of interest in empathy is closely connected to the recent neurobiological discovery of mirror neurons. Although the concept of empathy has been widely deployed, we shall focus upon one main psychological function it serves: enabling us to understand other peoples’ intentions. In this essay we will draw on neuroscientific, psychological, and philosophical literature in order to investigate the relationships between mirror neurons and empathy as to intention understanding. Firstly, it will be explored whether mirror neurons are the neural basis of our empathic capacities: a vast array of empirical results appears to confirm this hypothesis. Secondly, the higher level capacity of reenactive empathy will be examined and the question will be addressed whether philosophical analysis alone is able to provide a foundation for this more abstract level of empathy. The conclusion will be drawn that both empirical evidence and philosophical analysis can jointly contribute to the clarification of the concept of empathy.     

Effects of Augmenting Response Options on MMPI–2 RC Scale Psychometrics

A number of empirical investigations indicate that tests with a greater number of response options tend to yield better psychometric performance. We hypothesized that a version of the MMPI–2 with a polytomous response format would outperform the standard dichotomous format in terms of observed score reliability and validity. Two versions of the MMPI–2 RC scales were administered consecutively in counterbalanced order to 199 undergraduate students attending a large Midwestern university: the standard true–false version, and an experimental version containing 4 response options (very true, mainly true, slightly true, and false, not at all true). After participants completed both versions, 2 scales from the Multidimensional Personality Questionnaire (MPQ) were administered to assess differences in convergent validity. Results showed enhancements in reliability for all RC scale scores and increases in the convergent validity of scores. Directions for further investigation and potential implications for future test development are discussed.     

Simulating Ordinal Data

The increasing use of ordinal variables in different fields has led to the introduction of new statistical methods for their analysis. The performance of these methods needs to be investigated under a number of experimental conditions. Procedures to simulate from ordinal variables are then required. In this article, we deal with simulation from multivariate ordinal random variables. We propose a new procedure for generating samples from ordinal random variables with a prespecified correlation matrix and marginal distributions. Its features are examined and compared with those of its main competitors. A software implementation in R is also provided along with examples of its application.     

Spirituality and Religiosity in the Aftermath of a Natural Catastrophe in Italy

The aim of this study is to assess the influence of spirituality and religiousness on the psychological traumatic effects of a catastrophic event in a population that had been exposed to an earthquake compared with a control population that had not been exposed. A total of 901 people have been evaluated using: (1) Brief Multidimensional Measure of Religiousness/Spirituality; (2) Impact of Event Scale and (3) Trauma and Loss Spectrum-Self Report (TALS-SR). Self-perceptions of spirituality and religiousness were used to rank the samples, distinguishing between spiritual and religious, spiritual-only, religious-only and neither spiritual nor religious groups. The sample that had experienced the earthquake showed lower scores in spiritual dimension. The religious-only group of those who were exposed to the earthquake demonstrated TALS-SR re-experiencing and arousal domain scores similar to the population that was not exposed. A weakening of spiritual religiosity in people having difficulty coping with trauma is a consistent finding. We further observed that the religious dimension helped to buffer the community against psychological distress caused by the earthquake. The religiosity dimension can positively affect the ability to cope with traumatic experiences.     

The Effects of Video-Taped Feedback on Form,Accuracy, and Latency in an Open and Closed Environment

40 college women performed a modification of the classical fencing lunge against 2 laterally-arranged targets, under closed and open environmental conditions. Form (rating scale), accuracy (proximity to target center), and response latency were taken to measure the effects of video-taped feedback (VT). Administration of VT with specific instructions to direct S’s attention to parts of the display resulted in closer approximation of the externally-imposed form, higher accuracy, and shorter response latency. Performing the skill in the closed environmental condition resulted in less deviation from the imposed form, higher accuracy scores, and longer response latency. No significant correlations were found between imposed form and accuracy.     

Researching a client's experience of preconceptions of therapy - A discourse analysis

This paper uses discourse analysis to look at clients' preconceptions of therapy, through the presentation of a case study. Further findings suggest that discourse analysis may be a useful approach to helping psychotherapists and counsellors as part of their practice.     

The Cognitive Effectiveness of Subtitle Processing

In an experimental study, we analyzed the cognitive processing of a subtitled film excerpt by adopting a methodological approach based on the integration of a variety of measures: eye-movement data, word recognition, and visual scene recognition. We tested the hypothesis that the processing of subtitled films is cognitively effective: It leads to a good understanding of film content without requiring a significant tradeoff between image processing and text processing. Following indications in the psycholinguistic literature, we also tested the hypothesis that two-line subtitles whose segmentation is syntactically incoherent can have a disruptive effect on information processing and recognition performance. The results highlighted the effectiveness of subtitle processing: Regardless of the quality of line segmentation, participants had a good understanding of the film content, they achieved good levels of performance in both word and scene recognition, and no tradeoff between text and image processing was detected. Eye-movement analyses enabled a further characterization of cognitive processing during subtitled film viewing. This article discusses the theoretical implications of the findings for both subtitling and multiple-source communication and highlights their methodological and applied implications.
