‘Liars are less detailed’ …So what? Comparing two recall instructions to detect deception within-subject

Most deception research provides between-subject results (e.g., liars give on average less detailed accounts), which might be of limited value for professionals evaluating credibility on an individual basis. This study examines the optimal instructions of a within-subject multiple recalls strategy to detect deception. A total of 110 participants, divided into a Lie and Truth group, were randomly placed into four interview conditions: two Basic report-everything instructions (1), a Basic recall followed by an Open depth instruction (2), a Basic recall followed by the Verifiability Approach and Information Protocol (3), and two recalls with the Verifiability Approach and Information Protocol (4). All recalls were coded for total details and verifiable details. Group (lie and truth) × Recall (first and second) was only significant in condition 3, with truth tellers providing more verifiable details in the second recall than the first. A simple within-subject decision rule was derived, allowing a 76.9% discrimination rate. Professionals can optimally evaluate credibility using two recalls (Basic recall followed by Verifiability Approach and Information Protocol) and observing the evolution of verifiable details.     

To What Extent do we Hear Phonemic Contrasts in a Non-native Regional Variety? Tracking the Dynamics of Perceptual Processing with EEG

This combined ERP and behavioral experiment explores the dynamics of processing during the discrimination of vowels in a non-native regional variety. Southern listeners were presented with three word forms, two of which are encountered in both Standard and Southern French ([kot] and [kut]), whereas the third one exists in Standard but not Southern French ([kot]). EEG recordings suggest that all of the word pairs were discriminated by the listeners, although discrimination arose about 100ms later for the pairs which included the non-native word form than for those which contained word forms common to both French varieties. Behavioral data provide evidence that vowel discrimination is sensitive to the influence of the listeners’ native phonemic inventory at a late decisional stage of processing.     

Violent Video Games Stress People Out and Make Them More Aggressive

It is well known that violent video games increase aggression, and that stress increases aggression. Many violent video games can be stressful because enemies are trying to kill players. The present study investigates whether violent games increase aggression by inducing stress in players. Stress was measured using cardiac coherence, defined as the synchronization of the rhythm of breathing to the rhythm of the heart. We predicted that cardiac coherence would mediate the link between exposure to violent video games and subsequent aggression. Specifically, we predicted that playing a violent video game would decrease cardiac coherence, and that cardiac coherence, in turn, would correlate negatively with aggression. Participants (N = 77) played a violent or nonviolent video game for 20 min. Cardiac coherence was measured before and during game play. After game play, participants had the opportunity to blast a confederate with loud noise through headphones during a reaction time task. The intensity and duration of noise blasts given to the confederate was used to measure aggression. As expected, violent video game players had lower cardiac coherence levels and higher aggression levels than did nonviolent game players. Cardiac coherence, in turn, was negatively related to aggression. This research offers another possible reason why violent games can increase aggression—by inducing stress. Cardiac coherence can be a useful tool to measure stress induced by violent video games. Cardiac coherence has several desirable methodological features as well: it is noninvasive, stable against environmental disturbances, relatively inexpensive, not subject to demand characteristics, and easy to use.

Passion in the romantic sphere: A look at relational outcomes

Based on the Dualistic Model of Passion (Vallerand et al. in J Pers Soc Psychol 85:756–767, 2003), a bidimensional perspective on romantic passion, that distinguishes between harmonious and obsessive passions, is proposed. The present research aimed at examining how these two types of romantic passion relate to indices of relationship quality, how one’s own passions are associated with one’s partner’s passions and relationship quality, and how the two types of passion relate to relationship stability over time. Study 1 revealed that harmonious passion was more strongly associated with high relationship quality than obsessive passion. Using a dyadic design, Study 2 revealed that the findings of Study 1 applied to both genders. In addition, one’s own passion predicted partner’s relationship quality, partners were not always matched in terms of the predominant type of passion, and passion matching did not predict relationship quality. Finally, Study 3 revealed that types of passion predicted relationship status over a 3-month period.     

Individual Differences in Mediators and Reactions to a Personal Safety Threat Message

Individual differences in processing information about a personal threat message about bisphenol A (BPA) risk were examined using the threat orientation model (Thompson &; Schlehofer, 2008 Thompson , S. C. , &; Schlehofer , M. M. ( 2008 ). Control, denial, and heightened sensitivity reactions to personal threat: Testing the generalizability of the threat orientation approach . Personality and Social Psychology Bulletin , 34 , 1070 – 1083 .[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]). Adults (N = 448) read a risk message concerning BPA in plastics. Threat orientations, intentions to protect oneself from BPA risk, and emotional and cognitive reactions to the message were measured. Individuals with different approaches to threat reached different conclusions about the message and used different information in that process. These findings suggest that consideration of individual differences could improve the predictive ability of existing theoretical models and the effectiveness of health and safety messages.     

Contrastación de teorías de representación y razonamiento sobre silogismos lineales

Resumen

El objetivo de esta investigación es la comprobación de la capacidad predictiva de los distintos modelos existentes sobre razonamiento y representación en silogismos lineales: modelo de la imagen, lingüístico-proposicional, mixto y de niveles de representación. Se utilizaron 64 tipos de silogismos lineales con el fin de cumplir los requisitos mínimos necesarios para utilizar la metodología empleada. Aunque los resultados obtenidos no presentan diferencias estadísticamente significativas entre los dos modelos con mayor capacidad predictiva, el modelo de niveles de representación supera al modelo mixto.     

Cartesian Method and the Aristotelian-Scholastic Method

In book one of the Consolation of Philosophy, Boethius is portrayed as a man who suffers because he forgot philosophy. Scholars have underestimated the significance of this portrayal and considered it a literary device the goal of which is simply to introduce the discussion that follows. In this paper, I show that this view is mistaken since it overlooks that this portrayal of Boethius is the key for the understanding of the whole text. The philosophical therapy that constitutes the core of the ‘Consolation’ can in fact be properly evaluated only if we recognize the condition it is designed to cure. Through the portrayal of Boethius's forgetfulness, the ‘Consolation’ illustrates that it is the very nature of philosophical knowledge that makes it susceptible to being forgotten. Philosophical knowledge can (i) turn into misology, when it appears unable to solve certain problems, and (ii) be overrun by strong emotions. The therapy offered in the ‘Consolation’ is designed to make Boethius aware of the ‘fragility’ of philosophical knowledge and show him how to ‘strengthen’ it. He is taught how to more fully embody philosophy's precepts and that philosophy's inability to solve certain problems reveals not its failures but its limits.     

Decision making is affected in obstructive sleep apnoea syndrome

We assessed decision making in 20 patients newly diagnosed with obstructive sleep apnoea (OSA) and 20 healthy controls with the Iowa Gambling Task (IGT), which evaluates the ability to learn to sacrifice immediate rewards in favour of long‐term gains. A standard neuropsychological battery was administered. Switching scores tended to be lower in patients. Patients persisted in selecting risky decks throughout the IGT, whereas controls behaved normally. Performance was correlated with hypoxaemia. Brain regions underlying decision making may be affected by OSA‐related hypoxaemia.     

Trauma-Related Negative Cognitions Mediate the Relationship Between Avoidant Personality Beliefs and Impeded Response to Psychotherapy for PTSD

There is strong research evidence for the association of personality pathology and posttraumatic stress disorder (PTSD), as well as trauma-related negative cognitions (TRNC) and PTSD symptoms. However, the relationship between personality pathology and TRNC in the context of PTSD is mostly unknown. In the present study, we aimed to examine whether avoidant and borderline personality beliefs (PB, indicator of personality pathology) could predict therapy outcome in PTSD, and whether the relationship between PB and therapy outcome could be mediated by TRNC. Sixty patients with PTSD were assessed for PB, TRNC and PTSD symptoms at baseline, and for PTSD symptoms at the termination of Prolonged Exposure Therapy. Baseline avoidant PB predicted significant variance in PTSD symptoms at termination over and above baseline PTSD symptoms (16% reduction in treatment effect per SD on avoidant PB). Moreover, TRNC at baseline fully mediated the relationships between baseline avoidant PB and PTSD symptoms at termination. This is the first study to show that avoidant PB predicts treatment response in PTSD, and that patients with avoidant beliefs are more vulnerable to have TRNC, which are associated with impeded therapy response. Our results highlight the importance of targeting both dysfunctional PB and TRNC in PTSD interventions.
