Verbal and visual causal arguments

The present paper analyzes how verbalizations and visualizations can be used to justify and dispute causal claims. The analysis is based on a taxonomy of 27 causal arguments as they appear in ordinary language. It is shown how arguments from spatio-temporal contiguity, covariation, counterfactual necessity, and causal mechanisms, to name only a few, are visualized in persuasive uses of tables, graphs, time series, causal diagrams, drawings, maps, animations, photos, movies, and simulations. The discussion centers on how these visual media limit the argumentative moves of justifying, disputing, and qualifying claims; how they constrain the representation of observational, explanatory, and abstract knowledge in the premises of causal arguments; and how they support and externalize argument-specific inferences, namely generalizations, comparisons, mental simulations, and causal explanations.     

Evaluation of inpatient dialectical-behavioral therapy for borderline personality disorder--a prospective study

Dialectical-Behavioral Therapy for Borderline Personality Disorder (DBT) developed by M. Linehan is specifically designed for the outpatient treatment of chronically suicidal patients with borderline personality disorder. Research on DBT therapy, its course and its results has focused to date on treatments in an outpatient setting. Hypothesizing that the course of therapy could be accelerated and improved by an inpatient setting at the beginning of outpatient DBT, we developed a treatment program of inpatient therapy for this patient group according to the guidelines of DBT. It consists of a three-month inpatient treatment prior to long-term outpatient therapy. In this pilot study 24 female patients were compared at admission to the hospital, and at one month after discharge with respect to psychopathology and frequency of self-injuries. Significant improvements in ratings of depression, dissociation, anxiety and global stress were found. A highly significant decrease in the number of parasuicidal acts was also reported. Analysis of the average effect sizes shows a strong effect which prompts the development of a randomized controlled design.     

A structural and intertextual reading of Freud's "On Dreams"

By using the framework of a "quest" narrative based on literary allusions to Virgil's Aeneid and Goethe's Wilhelm Meister's Apprenticeship, Freud transformed the 500 pages of The Interpretation of Dreams into some fifty pages entitled "On Dreams." This paper elucidates the narrative means by which Freud achieved the feat of turning a highly complex, lengthy theoretical work into an engaging narrative. Its main plot, provided by a specimen dream, reveals Freud's working through of the personal and professional conflicts of his life up to 1901, and serves as a practical demonstration of and paradigm for the process of working through in psychoanalysis.     

Incidence of Savant Syndrome in Finland

The general incidence of Savant Syndrome was assessed in Finland. First, a survey was made of all 583 facilities which served people with mental retardation. Second, letters asking for information regarding people with Savant Syndrome were published in two key Finnish journals of the field. We received reports of 45 cases of Savant Syndrome. This makes an incidence rate of 1.4 per 1,000 people with mental retardation. The most common form of exceptional skills was calendar calculation, followed by feats of memory.     

20‐Item Toronto Alexithymia Scale: Do difficulties describing feelings assess proneness to shame instead of difficulties symbolizing emotions?

A hallmark of alexithymia is the difficulty putting emotional states into words which has to be differentiated from problems to communicate emotion to others. Shame proneness is a personality trait that is expected to be closely related to a reduced emotional self-disclosure in social interactions. The present investigation was conducted to examine construct validity of the Difficulties Describing Feelings scale of the 20-Item Toronto Alexithymia Scale (TAS-20). The TAS-20 was administered to 68 subjects (30 psychiatric inpatients and 38 normals) along with the Levels of Emotional Awareness Scale (LEAS), a direct measure of the ability to express feelings verbally, and the Shame-Guilt-Scale. Difficulties Describing Feelings was associated with shame assessing scales but not with guilt assessing scales or the LEAS. Thus, in view of our data one should be cautious in interpreting scores from the TAS-20 scale Difficulties Describing Feelings as indices of a difficulty to symbolize one's emotions. Instead, this TAS-20 scale seems to evaluate aspects of social shame.     

Task-set switching and long-term memory retrieval

The authors tested the hypothesis of a close relationship between the intentional component of task-set switching ("advance reconfiguration;" R. D. Rogers & S. Monsell, 1995) and long-term memory (LTM) retrieval. Consistent with this hypothesis, switch costs are reported to be larger when the switched-to task involves high retrieval demands (i.e., retrieval of episodic information) than when it involves low retrieval demands (i.e., retrieval of semantic information). In contrast, switch costs were not affected by a primary-task difficulty manipulation unrelated to intentional retrieval demands (Experiment 2). Also, the retrieval-demand effect on switch costs was eliminated when time for advanced preparation or task cues explicitly specifying the task rules were provided (Experiment 3). Overall, results were consistent with the hypothesis that the intentional switch-cost component reflects the time demands of retrieving appropriate task rules from LTM.     

Hindsight bias: a by-product of knowledge updating?

With the benefit of feedback about the outcome of an event, people's recalled judgments are typically closer to the outcome of the event than their original judgments were. It has been suggested that this hindsight bias may be due to a reconstruction process of the prior judgment. A model of such a process is proposed that assumes that knowledge is updated after feedback and that reconstruction is based on the updated knowledge. Consistent with the model's predictions, the results of 2 studies show that knowledge after feedback is systematically shifted toward feedback, and that assisting retrieval of the knowledge prior to feedback reduces hindsight bias. In addition, the model accounts for about 75% of cases in which either hindsight bias or reversed hindsight bias occurred. The authors conclude that hindsight bias can be understood as a by-product of an adaptive process, namely the updating of knowledge after feedback.     

Is age-related stability of subjective well-being a paradox? Cross-sectional and longitudinal evidence from the Berlin Aging Study

Subjective well-being is thought to remain relatively stable into old age despite health-related losses. Age and functional health constraints were examined as predictors of individual differences and intraindividual change in subjective well-being, as indicated by positive and negative affect, using cross-sectional (N = 516) and longitudinal (N = 203) samples from the Berlin Aging Study (age range 70-103 years). In cross-sectional and longitudinal analyses, age and functional health constraints were negatively related to positive affect but unrelated to negative affect. Cross-sectionally, controlling for functional health constraints reversed the direction of the relationship between age and positive affect and produced a negative association between age and negative affect. Findings suggest two qualifications to the average stability of overall subjective well-being: Only some dimensions of subjective well-being remain stable, while others decline; age per se is not a cause of decline in subjective well-being but health constraints are.     

The role of recent life events in the onset of obsessive-compulsive disorder

Although many investigations into the onset of obsessive-compulsive disorder (OCD) suggest the occurrence of potential life events as triggering factors, such an association has not been well studied to date. The purpose of the present paper is to review the literature on OCD onset in order to determine whether OCD is triggered by recent life events, what specific events may serve as triggers, and the clinical and research implications of these factors. Overall, the available studies do not consistently support the theory that OCD is triggered by specific antecedent life events. However, there is a body of evidence to support the theory that the specific life events of pregnancy and birth of a child can trigger OCD. This apparent association has led to the investigation of certain neurohormonal factors, including changes in estrogen or oxytocin levels, that may be of etiopathogenetic significance in OCD. Confirming such associations may allow clinicians to provide more targeted preventive and therapeutic interventions.     

The bar-cross-ellipse illusion: alternating percepts of rigid and nonrigid motion based on contour ownership and trackable feature assignment

We present a new multistable stimulus generated by continuously rotating an ellipse behind four fixed occluders. Despite the stimulus remaining constant, observers can alternate between one of four percepts: (1) a continuously morphing cross; (2) two independent perpendicular bars oscillating in depth; (3) a rigidly rotating ellipse observed behind the occluders; (4) a fixed cross observed through a continuously rotating, elliptical aperture. Interestingly, the initial percept naive observers tend to see is percept 1, which is the only nonrigid motion percept. This appears to be a violation of the hypothesized 'rigidity heuristic' in which rigid motion percepts tend to be perceived over retinally equivalent nonrigid ones. Here, we describe the relationships between each of the percepts and the assignment of contour ownership and figure/ground segmentation.
