Asymptotic judgment of cause in a relative validity paradigm

We report three experiments in which we tested asymptotic and dynamic predictions of the Rescorla-Wagner (R-W) model and the asymptotic predictions of Cheng's probabilistic contrast model (PCM) concerning judgments of causality when there are two possible causal candidates. We used a paradigm in which the presence of a causal candidate that is highly correlated with an effect influences judgments of a second, moderately correlated or uncorrelated cause. In Experiment 1, which involved a moderate outcome density, judgments of a moderately positive cause were attenuated when it was paired with either a perfect positive or perfect negative cause. This attenuation was robust over a large set of trials but was greater when the strong predictor was positive. In Experiment 2, in which there was a low overall density of outcomes, judgments of a moderately correlated positive cause were elevated when this cause was paired with a perfect negative causal candidate. This elevation was also quite robust over a large set of trials. In Experiment 3, estimates of the strength of a causal candidate that was uncorrelated with the outcome were reduced when it was paired with a perfect cause. The predictions of three theoretical models of causal judgments are considered. Both the R-W model and Cheng's PCM accounted for some but not all aspects of the data. Pearce's model of stimulus generalization accounts for a greater proportion of the data.     

Positive facial affect looks healthy

A healthy appearance is linked to important behavioural outcomes. Here we investigated whether positive facial affect is a cue for perceived health. In study one, two groups of participants rated the perceived health or perceived happiness of a large set of faces with neutral expressions. Perceived happiness predicted perceived health, as did anthropometric measures of expression. In a second experimental study, we collected ratings of perceived health for a wide age range of target faces with either neutral or smiling expressions. Smiling faces were rated as being much healthier looking than neutral faces, confirming that facial expression plays a role in the perception of health. A third study investigating attractiveness as a possible mediator found that expression still had a significant direct effect on perceived health, after accounting for attractiveness. Together, these studies systematically show that facial affect plays a critical role in shaping our perceptions of health in others.     

Strategies included in cognitive behavioral therapy programs to treat internalized disorders: a systematic review

This review aimed to identify the strategies used in programs based on cognitive behavioral therapy (CBT) to prevent and treat symptoms of anxiety, depression, and internalized behaviors of children and adolescents. Based on an online search (ERIC, PsycInfo, Virtuose UQAM, and Google Scholar), 61 studies describing different cognitive behavioral programs were selected. Results showed that 40 strategies were implemented in at least one program. However, none of the strategies were systematically present in all programs, and only few were reported in more than 50% of the studies. Cognitive restructuring and problem-solving were the most popular strategies to treat depressive symptoms, whereas anxiety programs also generally included relaxation and exposure. Furthermore, six strategies were identified in a single anxiety program, whereas nine strategies were implemented in only one depression program. These results suggest that in anxiety and depression programs designed for children and adolescents, the label “CBT” encompasses a wide variety of programs with only few similar strategies. Such findings highlight the need to define a common basis for CBT programs, in order to better reflect CBT theory and to identify the effectiveness of the strategies included in these programs.     

Implicit self and the right hemisphere: Increasing implicit self‐esteem and implicit positive affect by left hand contractions

Unilateral hand contraction typically activates the contralateral hemisphere and has led to changes in psychological states and performances in previous research. Based on a right hemisphere model of the implicit self, we hypothesized and found that left hand contraction increases momentary levels of implicit self‐esteem (Studies 1 and 2) and implicit positive affect (Study 3). The findings are discussed with respect to potential differences between the hemispheres in implicit and explicit affective processing and how they can be integrated in the existing literature on hemisphere asymmetries.     

A randomized controlled pilot trial of acceptance and commitment training (ACT) for preventing stress-related ill health among future nurses

Background: Levels of stress and burnout increase during nursing education. This development has consequences for nursing students' health, learning, competence, and interest in quality issues in health care. Design: In a randomized controlled pilot trial with a sample of 113 nursing students the effect of an intervention using techniques from acceptance and commitment training (ACT) to prevent the development of stress and burnout was evaluated. Method: The 6 × 2-hour program was compared to standard treatment (reflection seminars) post-intervention and at a three-month follow-up using longitudinal analysis of mean response profiles. Mechanisms of change were investigated using a baseline-post intervention two-mediator model. Results: The intervention resulted in increased mindful awareness and decreased experiential avoidance, as well as decreased perceived stress and burnout. Levels of mindful awareness and perceived stress were sustained at follow-up. The proposed mechanisms of change were partly supported by the data. Conclusion: This study shows that techniques from ACT might have the potential to contribute to preventing the development of stress and burnout during nursing education. However, additional studies are needed to validate these results.     

Nikolai Lossky’s Reception and Criticism of Husserl

Nikolai Lossky is key to the history of the Husserl-Rezeption in Russia. He was the first to publish a review of the Russian translation of Husserl’s first volume of the Logische Untersuchungen that appeared in 1909. He also published a presentation and criticism of Husserl’s transcendental idealism in 1939. An English translation of both of Lossky’s publications is offered in this volume for the first time. The present paper, which is intended as an introduction to these documents, situates Lossky within the Rezeptionsgeschichte of Husserl in Russia and explains why he is central to it. It also explains what Lossky principally found in Husserl: he saw in the latter’s critique of psychologism support for his own ontology, epistemology, and axiology. Lossky characterizes his ontology as an ideal-realism. According to ideal-realism, both the realm of ideal beings (in Plato’s sense) and the realm of real beings (i.e., the world of becoming) are mind-independent. Per his epistemology, which he calls “intuitivism,” real beings are intuited by sensual intuition and ideal beings by intellectual intuition. The realm of ideal beings includes the subrealm of values, which is intuited by axiological intuition. This thoroughly realist conception contrasted sharply with the subjectivist tendencies of the time. So, when Lossky took cognizance of Husserl’s critique of psychologism, he thereupon found an ally in his battle against the various subjectivisms. But, when Husserl took the transcendental idealist turn, Lossky was at the forefront of the backlash against the new direction Husserl wanted to give to phenomenology.     

On the role of passion in performance

The present paper reports two studies designed to test the Dualistic Model of Passion with regard to performance attainment in two fields of expertise. Results from both studies supported the Passion Model. Harmonious passion was shown to be a positive source of activity investment in that it directly predicted deliberate practice (Study 1) and positively predicted mastery goals which in turn positively predicted deliberate practice (Study 2). In turn, deliberate practice had a direct positive impact on performance attainment. Obsessive passion was shown to be a mixed source of activity investment. While it directly predicted deliberate practice (Study 1) and directly predicted mastery goals (which predicted deliberate practice), it also predicted performance-avoidance and performance-approach goals, with the former having a tendency to facilitate performance directly, and the latter to directly negatively impact on performance attainment (Study 2). Finally, harmonious passion was also positively related to subjective well-being (SWB) in both studies, while obsessive passion was either unrelated (Study 1) or negatively related to SWB (Study 2). The conceptual and applied implications of the differential influences of harmonious and obsessive passion in performance are discussed.     

Analyzing head roll and eye torsion by means of offline image processing

Ocular torsion is a key problem in the understanding of many visual perceptual effects. However, since it is difficult to record, its integration with other sensorimotor signals is still poorly understood. Unfortunately, eyetracker systems are generally not dedicated to the monitoring of eye torsion. In addition, the classical methods used with video-based systems present some limits in the accuracy of torsion calculation. These limits are especially related to the detection of pupil center and the effects of pupil size changes. This article aims at (1) proposing a solution to analyze ocular torsion together with head roll using EyeLink II or similar equipment, (2) reviewing and adapting classical polar cross-correlation methods in order to improve the accuracy of torsion measurement, (3) providing a lower-cost method compared with the existing ones. Video sequences issued from the EyeLink II host computer monitor were recorded by means of a second computer equipped with a video acquisition card and converted into image sequences. Images were analyzed with algorithms of pupil center detection (median-based algorithm), torsion analysis (adapted polar cross-correlation method which takes into account pupil size variations) and marker tracking (head roll analysis). This method was tested on virtual eye images. Results are discussed with respect to other algorithms found in the literature.     

Verbal,mathematics, and physical education self-concepts and achievements: An extension and test of the Internal/External Frame of Reference Model

ObjectivesThe Internal/External Frame of Reference Model (I/E model; e.g., Marsh, 1986) posits that verbal achievement (Ach) produces a lower mathematics self-concept (SC) and that, conversely, mathematics Ach fosters a lower verbal SC after controlling for prior Ach in each domain. The present study extended this model by adding another school subject that has not been previously investigated, namely physical education (PE). The central goal was to verify whether Ach in PE positively or negatively predicts academic SC in the mathematics and verbal domains.DesignProspective study over one school year.MethodsParticipants were 451 French high school students (mean age = 13.5). Ach scores in mathematics, French and PE were gathered at the beginning of the school year. At the end of this one, students completed a questionnaire to assess their SC in the three school subjects. Results: Structural Equation Modelling results revealed, according to the I/E model, negative paths between mathematics Ach and verbal SC, and between verbal Ach and mathematics SC. Results also revealed singular relationship patterns between the two traditional school subjects and PE. A positive path between PE Ach and mathematics SC was observed whereas the path with the verbal SC was non-significant.ConclusionPE could have benefits to increase SC in other school subject such as mathematics. Broader implications of results for the I/E model are discussed.
