The impact of psychological distance on integrative internal dialogs

Negotiators more distanced from the negotiated goal more often exhibit integrative behavior, which maximizes both their individual and joint outcomes. Based on the assumption of an analogy between interpersonal negotiations and internal dialogs simulating social relationships, an experiment was carried out. It aimed to verify if psychological distance (proximal vs. distant perspective on the situation enacted in an internal dialog) affects the processes of integration and confrontation and, consequently, increases the frequency of integrative dialogs. Data from 115 participants (56 women) were analyzed. An increase in psychological distance was found to reduce the intensity of the confrontation process and to cause an increase in the number of integrative internal dialogs.     

Spatial imagery of novel places based on visual scene transformation

The hippocampus is known to maintain memories of object-place associations that can produce a scene expectation at a novel viewpoint. To implement such capabilities, the memorized distances and directions of an object from the viewer at a fixed location should be integrated with the imaginary displacement to the new viewpoint. However, neural dynamics of such scene expectation at the novel viewpoint have not been discussed. In this study, we propose a method of coding novel places based on visual scene transformation as a component of the object-place memory in the hippocampus. In this coding, a novel place is represented by a transformed version of a viewer’s scene with imaginary displacement. When the places of individual objects are stored with the coding in the hippocampus, the object’s displacement at the imaginary viewpoint can be evaluated through the comparison of a transformed viewer’s scene with the stored scene. Results of computer experiments demonstrated that the coding successfully produced scene expectation of a three object arrangement at a novel viewpoint. Such the scene expectation was retained even without similarities between the imaginary scene and the real scene at the location, where the imaginary scenes only functioned as indices to denote the topographical relationship between object locations. The results suggest that the hippocampus uses the place coding based on scene transformation and implements the spatial imagery of object-place associations from the novel viewpoint.     

Spinoza on essence and ideal individuation

My project in this paper is to fill a gap in Spinoza's theory of metaphysical individuation. In a few brief passages of the Ethics, Spinoza manages to explain his views on the nature of composition and the part-whole relation, the metaphysical facts which ground the individuation of simple bodies and the extended individuals they compose, and the persistence of one and the same individual through time and mereological change. Yet Spinoza nowhere presents a corresponding account of the individuation of simple ideas, or the minds such ideas compose. While it is initially tempting to locate the details of such an account in Spinoza's views on the relation between the mental and physical domains, I argue here that such approaches fail, in conflicting with Spinoza's insistence that the mental and the physical are conceptually and explanatorily independent. By contrast, I show that for Spinoza, each idea essentially possesses the property of affirming the existence of its object, and that such properties are well-suited to serve as the principle of ideal individuation Spinoza never explicitly provided.     

The Effectiveness of Cultural Adjustment and Trauma Services (CATS): Generating Practice-Based Evidence on a Comprehensive, School-Based Mental Health Intervention for Immigrant Youth

A collaborative study of Cultural Adjustment and Trauma Services (CATS), a comprehensive, school-based mental health program for traumatized immigrant children and adolescents, was conducted to generate practice-based evidence on the service delivery model across two school districts. Program effectiveness was assessed by testing whether client functioning and PTSD symptoms improved as a result of 7 separate service elements. An array of clinical services including CBT, supportive therapy, and coordinating services were provided to all students, and an evidence-based intervention for trauma, TF-CBT, was implemented with a subset of students. Greater quantities of CBT and supportive therapy increased functioning, while greater quantities of coordinating services decreased symptoms of PTSD. TF-CBT services were associated with both improved functioning and PTSD symptoms, although TF-CBT was implemented with fidelity to the overall comprehensive service model rather than the structured intervention model. Results suggest the comprehensive school-based model was effective, though different service components affected different student outcomes. Implications of these findings for immigrant mental health interventions and implementing structured evidence-based practices into community mental health programs are discussed. Suggestions are made for future research on existing mental health practices with immigrants.     

Supporting the Need for an Integrated System of Care for Youth with Co-occurring Traumatic Stress and Substance Abuse Problems

Adolescents are at high risk for violence exposure and initiation of drug use. Co-occurring substance use and trauma exposure are associated with increased risk of mental health disorders, school underachievement, and involvement with multiple systems of care. Coordination and integration of systems of care are of utmost importance for these vulnerable youth. This study delineates the negative sequelae and increased service utilization patterns of adolescents with a history of trauma, substance abuse, and co-occurring trauma and substance abuse to support the need for integrated mental health and substance abuse services for youth. Data from two national sources, the National Child Traumatic Stress Network and Center for Substance Abuse Treatment demonstrate the increased clinical severity (measured by reports of emotional and behavioral problems), dysfunction, and service utilization patterns for youth with co-occurring trauma exposure and substance abuse. We conclude with recommendations for an integrated system of care that includes trauma-informed mental health treatment and substance abuse services aimed at reducing the morbidity and relapse probability of this high-risk group.     

Perspective-taking and depth of theory-of-mind reasoning in sequential-move games

Theory-of-mind (ToM) involves modeling an individual's mental states to plan one's action and to anticipate others' actions through recursive reasoning that may be myopic (with limited recursion) or predictive (with full recursion). ToM recursion was examined using a series of two-player, sequential-move matrix games with a maximum of three steps. Participants were assigned the role of Player I, controlling the initial and the last step, or of Player II, controlling the second step. Appropriate for the assigned role, participants either anticipated or planned Player II's strategy at the second step, and then determined Player I's optimal strategy at the first step. Participants more readily used predictive reasoning as Player II (i.e., planning one's own move) than as Player I (i.e., anticipating an opponent's move), although they did not differ when translating reasoning outcome about the second step to optimal action in the first step. Perspective-taking influenced likelihood of predictive reasoning, but it did not affect the rate at which participants acquired it during the experimental block. We conclude that the depth of ToM recursion (related to perspective-taking mechanisms) and rational application of belief-desire to action (instrumental rationality) constitute separate cognitive processes in ToM reasoning.     

Representing Spatial Structure Through Maps and Language: Lord of the Rings Encodes the Spatial Structure of Middle Earth

Spatial mental representations can be derived from linguistic and non‐linguistic sources of information. This study tested whether these representations could be formed from statistical linguistic frequencies of city names, and to what extent participants differed in their performance when they estimated spatial locations from language or maps. In a computational linguistic study, we demonstrated that co‐occurrences of cities in Tolkien’s Lord of the Rings trilogy and The Hobbit predicted the authentic longitude and latitude of those cities in Middle Earth. In a human study, we showed that human spatial estimates of the location of cities were very similar regardless of whether participants read Tolkien’s texts or memorized a map of Middle Earth. However, text‐based location estimates obtained from statistical linguistic frequencies better predicted the human text‐based estimates than the human map‐based estimates. These findings suggest that language encodes spatial structure of cities, and that human cognitive map representations can come from implicit statistical linguistic patterns, from explicit non‐linguistic perceptual information, or from both.     

An Extension of SIC Predictions to the Wiener Coactive Model

The survivor interaction contrasts (SIC) is a powerful measure for distinguishing among candidate models of human information processing. One class of models to which SIC analysis can apply are the coactive, or channel summation, models of human information processing. In general, parametric forms of coactive models assume that responses are made based on the first passage time across a fixed threshold of a sum of stochastic processes. Previous work has shown that the SIC for a coactive model based on the sum of Poisson processes has a distinctive down-up-down form, with an early negative region that is smaller than the later positive region. In this note, we demonstrate that a coactive process based on the sum of two Wiener processes has the same SIC form.
