On the facilitatory effects of cognate words in bilingual speech production

There is a growing body of evidence showing that a word's cognate status is an important dimension affecting the naming performance of bilingual speakers. In a recent article, Kohnert extended this observation to the naming performance of an aphasic bilingual (DJ). DJ named pictures with cognate names more accurately than pictures with non-cognate names. Furthermore, having named the pictures in Spanish helped the subsequent retrieval (with a delay of one week between the two tests) of the same pictures' names in English, but only for pictures with cognate names. That is, there was a language transfer but only for those translation words that were phonologically similar. In this article we first evaluate the conclusions drawn from these results by Kohnert, and second we discuss the theoretical implications of the facilitatory effects of cognate words for models of speech production in bilingual speakers.     

The NEO-PI-3: a more readable revised NEO Personality Inventory

Use of the Revised NEO Personality Inventory (NEO-PI-R; Costa & McCrae, 1992) in adolescent samples has shown that a few respondents have difficulty with a subset of items. We identified 30 items that were not understood by at least 2% of adolescent respondents and 18 additional items with low item-total correlations, and we wrote 2 trial replacement items for each. We used self-report and observer rating data from 500 respondents aged 14 to 20 to select replacement items. The modified instrument retained the intended factor structure and showed slightly better internal consistency, cross-observer agreement, and readability (Flesch-Kincaid grade level = 5.3). The NEO-PI-3 appears to be useful in high school and college samples and may have wider applicability to adults as well.     

A cross-sectional evaluation of the factorial invariance of anxiety sensitivity in adolescents and young adults

This study examined the cross-sectional factorial invariance of anxiety sensitivity in an ethnically diverse sample of adolescents (n = 173; mean age 15.5 years) and young adults (n = 291; mean age 20.1 years). Research in adult and youth samples suggests that anxiety sensitivity is best understood as a hierarchical construct with several lower-order factors. Factor models based on previous research using both adult and youth samples were compared and a hierarchical model with three lower-order factors provided the best fit to the data. Results supported the hypothesis that the factor structure of the Anxiety Sensitivity Index was invariant across age and gender. The factor scores also demonstrated differential correlations with symptoms of anxiety and depression. Results are discussed with regard to construct validation and understanding the structure of anxiety sensitivity in youth.     

Learning first-pass structural attachment preferences with dynamic grammars and recursive neural networks

One of the central problems in the study of human language processing is ambiguity resolution: how do people resolve the extremely pervasive ambiguity of the language they encounter? One possible answer to this question is suggested by experience-based models, which claim that people typically resolve ambiguities in a way which has been successful in the past. In order to determine the course of action that has been "successful in the past" when faced with some ambiguity, it is necessary to generalize over past experience. In this paper, we will present a computational experience-based model, which learns to generalize over linguistic experience from exposure to syntactic structures in a corpus. The model is a hybrid system, which uses symbolic grammars to build and represent syntactic structures, and neural networks to rank these structures on the basis of its experience. We use a dynamic grammar, which provides a very tight correspondence between grammatical derivations and incremental processing, and recursive neural networks, which are able to deal with the complex hierarchical structures produced by the grammar. We demonstrate that the model reproduces a number of the structural preferences found in the experimental psycholinguistics literature, and also performs well on unrestricted text.     

The gender congruency effect and the selection of freestanding and bound morphemes: evidence from croatian

The authors report 3 picture-word interference experiments in which they explore some properties of the agreement process in speech production. In Experiment 1, Croatian speakers were asked to produce utterances in which the noun's gender value had an impact on the selection of gender-marked freestanding morphemes (pronouns) while ignoring the presentation of same- or different-gender distractor words. In Experiments 2 and 3, Croatian speakers were asked to name the same pictures using noun phrases in which the noun's gender value surfaced as an inflectional suffix. Different-gender distractors interfered more than same-gender distractors (the gender congruency effect) in Experiment 1, but not in Experiments 2 and 3. These contrasting results show that the cause of the gender congruency effect is not at the level where lexical-grammatical information is selected but at the level of selection of freestanding morphemes.     

Schrödinger logics

Schrödinger logics are logical systems in which the principle of identity is not true in general. The intuitive motivation for these logics is both Erwin Schrödinger's thesis (which has been advanced by other authors) that identity lacks sense for elementary particles of modern physics, and the way which physicists deal with this concept; normally, they understandidentity as meaningindistinguishability (agreemment with respect to attributes). Observing that these concepts are equivalent in classical logic and mathematics, which underly the usual physical theories, we present a higher-order logical system in which these concepts are systematically separated. A classical semantics for the system is presented and some philosophical related questions are mentioned. One of the main characteristics of our system is that Leibniz' Principle of the Identity of Indiscernibles cannot be derived. This fact is in accordance with some authors who maintain that quantum mechanics violates this principle. Furthermore, our system may be viewed as a way of making sense some of Schrödinger's logical intuitions about the nature of elementary particles.The authors very much would like to thank the anonymous referee for his quite interesting suggestions, which contributed significantly to improve the paper.Presented byJan Zygmunt;     

A new formulation of discussive logic

S. Jakowski introduced the discussive prepositional calculus D ₂as a basis for a logic which could be used as underlying logic of inconsistent but nontrivial theories (see, for example, N. C. A. da Costa and L. Dubikajtis, On Jakowski's discussive logic, in Non-Classical Logic, Model Theory and Computability, A. I. Arruda, N. C. A da Costa and R. Chuaqui edts., North-Holland, Amsterdam, 1977, 37–56). D ₂has afterwards been extended to a first-order predicate calculus and to a higher-order logic (cf. the quoted paper). In this paper we present a natural version of D ₂, in the sense of Jakowski and Gentzen; as a consequence, we suggest a new formulation of the discussive predicate calculus (with equality). A semantics for the new calculus is also presented.     

A comparison of five-factor personality dimensions in males with sexual dysfunction and males with paraphilia.

We compared personality profiles of men with sexual dysfunction (n = 51) to those of age-matched men with a primary diagnosis of paraphilia (n = 51) employing the NEO Personality Inventory (NEO-PI), a measure of the five-factor model. Preliminary analyses in a large sample of patients in a sexual behaviors consultation unit supported the reliability and factorial validity of the NEO-PI for this population. Analysis of variance showed significant differences between the dysfunctional and the paraphilic groups on two of the five NEO-PI domains, Neuroticism (N) and Agreeableness (A). The group personality profile of the sexually dysfunctional men was comparable to the normative sample of the NEO-PI, except for a slight elevation in N. By contrast, men with paraphilia had a personality profile marked by high N, low A, and low Conscientiousness (C). Treatment implications of the average personality profile of the sexual dysfunction group and the distinctive personality profile of paraphilic men are discussed.     

Clinical use of the five-factor model: an introduction.

In the past decade, clinical psychologists have developed a renewed appreciation of the value of assessment. At the same time, personality psychologists have come to agree on a fundamental taxonomy of personality traits, the five-factor model. Articles in this special series describe the model and its measurement and discuss applications in three different settings: general clinical practice, a sexual behaviors consultation unit, and a behavioral medicine clinic. This introduction raises questions about the use of personality profiles in psychodiagnosis, the range of applicability of the five-factor model, the utility of personality feedback in psychotherapy, the stability of personality scores among psychotherapy patients, and the feasibility of using personality scores to select optimal forms of treatment. This special series is intended to stimulate research on such topics.     

The roles of carbon monoxide and nitric oxide in the control of the neuroendocrine stress response: complementary or redundant

There is widespread evidence in favour of nitric oxide (NO) acting as a gaseous neurotransmitter in the central nervous system, diffusing from its cells of origin and affecting surrounding neuronal tissue in evanescent three-dimensional waves. This is also true of the hypothalamus, where amongst other activities NO inhibits stimulation of corticotrophin-releasing hormone (CRH) and vasopressin release by inflammatory stressors, effects thought to be mediated by binding with soluble guanylate cyclase (sGC). Carbon monoxide is being increasingly recognised as another gaseous neuromodulator, but with principal effects on other hemoproteins such as cyclo-oxygenase, and a distinctly different profile of localisation.NO is predominantly a pro-inflammatory agent in the periphery while CO is often anti-inflammatory. In the hypothalamus, the actions of CO are also distinct from those of NO,with marked antagonistic effects on the inflammatory release of vasopressin, both in vitro and in vivo, but with little involvement in the regulation of CRH. Thus, it would appear that these apparently similar gases exert quite distinct and separate effects, although they cause broadly similar overall changes in the secretion of neuroendocrine stress hormones. We conclude that these two gases may play significant but different roles in the control of the neuroendocrine stress response, but one common feature may be attenuation of inflammation-induced release of stress hormones.
