Spinoza’s error: Memory for truth and falsity

Two theoretical frameworks have been proposed to account for the representation of truth and falsity in human memory: the Cartesian model and the Spinozan model. Both models presume that during information processing a mental representation of the information is stored along with a tag indicating its truth value. However, the two models disagree on the nature of these tags. According to the Cartesian model, true information receives a “true” tag and false information receives a “false” tag. In contrast, the Spinozan model claims that only false information receives a “false” tag, whereas untagged information is automatically accepted as true. To test the Cartesian and Spinozan models, we conducted two source memory experiments in which participants studied true and false trivia statements from three different sources differing in credibility (i.e., presenting 100% true, 50% true and 50% false, or 100% false statements). In Experiment 1, half of the participants were informed about the source credibility prior to the study phase. As compared to a control group, this precue group showed improved source memory for both true and false statements, but not for statements with an uncertain validity status. Moreover, memory did not differ for truth and falsity in the precue group. As Experiment 2 revealed, this finding is replicated even when using a 1-week rather than a 20-min retention interval between study and test phases. The results of both experiments clearly contradict the Spinozan model but can be explained in terms of the Cartesian model.     

Paul Christian - A Jewish Dominican Preaching for the Jews

The so-called Barcelona disputation of 1263 was one of the earliest Jewish-Christian disputations in medieval Europe. The disputants were Paul Christian, a Jewish convert to Christianity and member of the Dominican order, and the well known Jewish sage Ramban (Rabbi Moses ben Nahman of Gerona). In the disputation Paul Christian used an innovative method: he attempted to prove the truth of basic Christian dogma, for instance that the Messiah had already come, by using classical Jewish texts, especially the Talmud. Paul Christian used the same method in his sermons which the Jews in the area were forced to listen to. When one analyses the arguments he employs, it becomes obvious how he alludes to both Jewish and Christian traditions in order to convince his listeners.     

The Psychology of the persecutor — With reference to Costa Gavras's film Music Box

This paper is based on the author's interpretation of the film Music Box by Costa Gavras. The external and internal preconditions in the development of a persecutor are discussed in an attempt to understand the process from a socio-psychological as well as psychoanalytic viewpoint. During crises of a social nature, earlier coping strategies lose their validity, resulting in a narcissistic blow to the individual's ego. Earlier repressed primitive aspects of the personality are reactivated. When the individual is exposed to a totalitarian ideology which promises salvation from anxiety, paranoid processes become anchored and may dominate.

The protagonist in the film is approached as a case-study. By reviewing his present and past actions, the process by which the young man became a persecutor is exemplified as well as the long-term effects upon his object relations.     

Exploring the Hierarchical Structure of the MMPI–2–RF Personality Psychopathology Five in Psychiatric Patient and University Student Samples

In this study our goal was to examine the hierarchical structure of personality pathology as conceptualized by Harkness and McNulty's (1994) Personality Psychopathology Five (PSY–5) model, as recently operationalized by the MMPI–2–RF (Ben-Porath & Tellegen, 2011) PSY–5r scales. We used Goldberg's (2006) “bass-ackwards” method to obtain factor structure using PSY–5r item data, successively extracting from 1 to 5 factors in a sample of psychiatric patients (n = 1,000) and a sample of university undergraduate students (n = 1,331). Participants from these samples had completed either the MMPI–2 or the MMPI–2–RF. The results were mostly consistent across the 2 samples, with some differences at the 3-factor level. In the patient sample a factor structure representing 3 broad psychopathology domains (internalizing, externalizing, and psychoticism) emerged; in the student sample the 3-factor level represented what is more commonly observed in “normal-range” personality models (negative emotionality, introversion, and disconstraint). At the 5-factor level the basic structure was similar across the 2 samples and represented well the PSY–5r domains.     

Implicit theories and motivational focus: Desired future versus present reality

People’s beliefs concerning their abilities differ. Incremental theorists believe their abilities (e.g., intelligence) are malleable; entity theorists believe their abilities are fixed (Dweck in Mindset: the new psychology of success. Random House, New York, 2007). On the basis that incremental theorists should emphasize improving their abilities for the future, whereas entity theorists should emphasize demonstrating their abilities in the present reality, we predicted that, when thinking about their wishes, compared to entity theorists, incremental theorists focus more toward the desired future than the present reality. We assessed participants’ motivational focus using a paradigm that differentiated how much they chose to imagine the desired future versus the present reality regarding an important wish (Kappes et al. in Emotion 11: 1206–1222, 2011). We found the predicted effect by manipulating (Study 1) and measuring implicit theories (Study 2), in the academic (Study 1) and in the sport domain (Study 2).     

Embarrassment and empathy before helping: How internal working models come into play

Prior research has described embarrassment and empathy as predictors of social helping and as self-conscious emotions involving reasoning about the self and others. It remains unclear how cognitive representations of the self and others relate to the two emotions as precursors of social helping. We examined 136 participants’ self-report measures of internal working models as well as dispositional embarrassability, empathic concern, personal distress, and perspective taking. Controlling all the other variables, embarrassability was primarily associated with the model of self and personal distress, whereas empathic concern was primarily associated with the model of others and perspective taking. Moreover, the association between personal distress and embarrassability was moderated by the interaction between models of others and perspective taking. The general proneness to distress arousal was also predicted by the interaction between models of self and others. The findings extended prior research linking internal working models and socio-cognitive emotions associated with helping.     

Dietary planning,self-efficacy,and outcome expectancies play a role in an online intervention on fruit and vegetable consumption

Objective: An online intervention to improve fruit and vegetable (FV) intake examines the role of planning, outcome expectancies, self-efficacy and gender. Women are not only expected to eat more FV than men, but they are also expected to be more responsive to nutritional advice and benefit more from treatment.

Method: A two-arm digital intervention with 269 men and 395 women (M_age = 41.2, SD_age = 11.45; range: 19–66 years) was conducted in Italy, Spain and Greece, followed up at three and six months, comparing a static with a dynamic, feedback-intensive platform.

Results: Linear mixed models yielded an increase in FV consumption in both the dynamic and the static intervention arms. In men, outcome expectancies were positively related to follow-up FV intake. Dietary planning interacted with self-efficacy on behavioural outcomes.

Conclusion: FV intake increased overall, and being a woman and involvement in planning facilitated behaviour change. Women seemed to be more engaged in the dynamic platform resulting in a higher amount of planning. Initial motivation, as indicated by outcome expectancies, seemed to be beneficial for men. Self-efficacious individuals benefitted from their engagement in planning, but self-efficacy did not compensate for failing to plan.     

Two mutations preventing PDZ-protein interactions of GluR1 have opposite effects on synaptic plasticity

The regulated trafficking of GluR1 contributes significantly to synaptic plasticity, but studies addressing the function of the GluR1 C-terminal PDZ-ligand domain in this process have produced conflicting results. Here, we resolve this conflict by showing that apparently similar C-terminal mutations of the GluR1 PDZ-ligand domain result in opposite physiological phenotypes during activity- and CamKII-induced synaptic plasticity.     

Comorbidity in youth with specific phobias: Impact of comorbidity on treatment outcome and the impact of treatment on comorbid disorders

The purpose of the present study was twofold. In an analysis of data from an existing randomized control trial of brief cognitive behavioral treatment on specific phobias (One-Session Treatment, OST; Ollendick et al., 2009), we examined 1) the effect of comorbid specific phobias and other anxiety disorders on treatment outcomes, and 2) the effect of treatment of the specific phobia on these co-occurring disorders. These relations were explored in 100 youth presenting with animal, natural environment, situational, and “other” types of phobia. Youth were reliably diagnosed with the Anxiety Disorders Interview Schedule for DSM-IV: Child and Parent versions (Silverman & Albano, 1996). Clinician severity ratings at post-treatment and 6-month follow-up were examined as were parent and child treatment outcome satisfaction measures. Results indicated that the presence of comorbid phobias or anxiety disorders did not affect treatment outcomes; moreover, treatment of the targeted specific phobias led to significant reductions in the clinical severity of other co-occurring specific phobias and related anxiety disorders. These findings speak to the generalization of the effects of this time-limited treatment approach. Implications for treatment of principal and comorbid disorders are discussed, and possible mechanisms for these effects are commented upon.
