Prolegomena to Concise Theories of Action

A new methodology for developing theories of action has recently emerged which provides means for formally evaluating the correctness of such theories. Yet, for a theory of action to qualify as a solution to the frame problem, not only does it need to produce correct inferences, but moreover, it needs to derive these inferences from a concise representation of the domain at hand. The new methodology however offers no means for assessing conciseness. Such a formal account of conciseness is developed in this paper. Combined with the existing criterion for correctness, our account of conciseness offers a framework where proposed solutions to the frame problem can be formally evaluated.     

湖南某村外出务工人员艾滋病知识掌握现状调查及分析

采取匿名问卷调查和个别深入访谈相结合的方式对103名外出务工人员进行调查,表明大部分外出务工人员对艾滋病的传播途径、预防等知识有一定了解,但是不够全面和准确,存在较多误解。今后应加大对外出务工人员的关注,采取更有效的艾滋病健康促进干预措施。     

Disjunctive logic programming with types and objects: The DLV system

The paper presents DLV⁺, a Disjunctive Logic Programming (DLP) system with object-oriented constructs, including classes, objects, (multiple) inheritance, and types. DLV⁺ is built on top of DLV (a state-of-the art DLP system), and provides a graphical user interface that allows one to specify, update, browse, query, and reason on knowledge bases. Two strong points of the system are the powerful type-checking mechanism and the advanced interface for visual querying.DLV⁺ is already used for the development of knowledge based applications for information extraction and text classification.

Jumping to conclusions and the continuum of delusional beliefs

The present study examined the jumping to conclusions reasoning bias across the continuum of delusional ideation by investigating individuals with active delusions, delusion prone individuals, and non-delusion prone individuals. Neutral and highly self-referent probabilistic reasoning tasks were employed. Results indicated that individuals with delusions gathered significantly less information than delusion prone and non-delusion prone participants on both the neutral and self-referent tasks, (p<.001). Individuals with delusions made less accurate decisions than the delusion prone and non-delusion prone participants on both tasks (p<.001), yet were more confident about their decisions than were delusion prone and non-delusion prone participants on the self-referent task (p=.002). Those with delusions and those who were delusion prone reported higher confidence in their performance on the self-referent task than they did the neutral task (p=.02), indicating that high self-reference impacted information processing for individuals in both of these groups. The results are discussed in relation to previous research in the area of probabilistic reasoning and delusions.     

Projective identification: A theoretical investigation of the concept starting from ’Notes on some schizoid mechanisms’1

This paper submits passages from four papers‐‘Notes on some schizoid mechanisms’ (Klein); ‘On identification’ (Klein); ‘Analysis of a schizophrenic state with depersonalization’ (Rosenfeld); and ‘Remarks on the relation of male homosexuality to paranoia, paranoid anxiety and narcissism’ (Rosenfeld)‐to a critical reading, enabling the theoretical premises which have produced the current, differing views on projective identification to be traced. These views revolve both around the role assigned to identification in the process and around the meaning of the expression‘to identify oneself with’ which in ‘On identification’ goes from ‘to feel similar to, or identical to the other’ to ‘to take another person as a model’. This legitimizes the inclusion of very different phenomena into the concept of projective identification. The author describes some uses of the term ‘projective identification’ and proposes the hypothesis that the process constitutes a way for managing otherness and the separateness of the object (be it external or internal, real or imaginary) that can compromise its reality to a greater or lesser degree. Covering a large set of phenomena, the author poses the question of whether it is useful to retain the term ‘projective identification’. She proposes an answer in the last part of the paper.     

Traditional difference-score analyses of reasoning are flawed

Studies of the belief bias effect in syllogistic reasoning have relied on three traditional difference score measures: the logic index, belief index, and interaction index. Dube, Rotello, and Heit (2010, 2011) argued that the interaction index incorrectly assumes a linear receiver operating characteristic (ROC). Here, all three measures are addressed. Simulations indicated that traditional analyses of reasoning experiments are likely to lead to incorrect conclusions. Two new experiments examined the role of instructional manipulations on the belief bias effect. The form of the ROCs violated assumptions of traditional measures. In comparison, signal detection theory (SDT) model-based analyses were a better match for the form of the ROCs, and implied that belief bias and instructional manipulations are predominantly response bias effects. Finally, reanalyses of previous studies of conditional reasoning also showed non-linear ROCs, violating assumptions of traditional analyses. Overall, reasoning research using traditional measures is at risk of drawing incorrect conclusions.     

Ambivalent sexism,attitudes towards menstruation and menstrual cycle‐related symptoms

The objective of the present study was to investigate the relationship between ambivalent sexism and beliefs and attitudes towards menstruation, and, in turn, to study the influence of these variables on menstrual cycle‐related symptoms. One hundred and six Mexican women completed the Ambivalent Sexism Inventory, the Beliefs about and Attitudes toward Menstruation Questionnaire and the Menstrual Distress Questionnaire. The higher scores on benevolent sexism were associated with the most positive attitudes towards menstruation and also with the belief that a menstruating woman should or should not do some activities and that menstruation keeps women from their daily activities. The higher scores on hostile sexism were associated with rejection of menstruation as well as with feelings of embarrassment about it. Beliefs about and attitudes towards menstruation predicted menstrual cycle‐related symptoms related to negative affect, impaired concentration and behavioural changes, but did not predict somatic symptoms. These results will be useful to health professionals and advocates who want to change the negative expectations and stereotypes of premenstrual and menstrual women and reduce the sexism and negative attitudes towards women that are evident in Mexican culture.     

Procedimientos analítico-racionales en la adaptación de tests. Adaptación al español de la batería de pruebas de razonamiento

Adapting a test between cultures or languages requires taking into account legal, linguistic, metric, and use-related considerations. Significantly more attention has been paid to the methodological aspects involved in the study of metric equivalence than to judgmental-analytical procedures prior to the empirical confirmation stage. However, considering the latter is crucial in the adaptation process. Along these lines, this paper seeks to describe and focus on the relevance of the previous stages, thereby offering a systematization process that comprises ten sections. This approach contributes to ensuring the construction of a test adapted and equivalent in as much as possible to the original. This process is exemplified by means of a Spanish language adaptation of a cognitive test originally designed in Portuguese for the Portuguese population, the Reasoning Test Battery.     

Useful lies: The twisted rationality of denial

He who increases knowledge increases sorrow.

Ecclesiastes 1:18

The truth will set you free.

John 8:32

Denial, or the habit of treating a real problem as if it were a nonissue, has both rational and irrational features. The interplay between these is best captured by a utilitarian-rationalist framework stretched to its limits. When in denial, people follow what they feel to be in their best interest by minimizing the psychosocial cost of acknowledging their problems. At its core, denial is thus based on a self-interested rationale of pain avoidance and harm minimization. Depending on the characteristics of the issue at hand, some of the effects are deeply ironic. I demonstrate this by starting from the simplest and most beneficial form of denial, before moving on to cases that are more complex and harmful. I also show how people can be liberated from denial when the practice has become counterproductive. Most of the mystery surrounding denial disappears when we accept that it is premised on a twisted kind of rationality.
