A place for nouns and a place for verbs? A critical review of neurocognitive data on grammatical-class effects

It is generally held that noun processing is specifically sub-served by temporal areas, while the neural underpinnings of verb processing are located in the frontal lobe. However, this view is now challenged by a significant body of evidence accumulated over the years. Moreover, the results obtained so far on the neural implementation of noun and verb processing appear to be quite inconsistent. The present review briefly describes and critically re-considers the anatomo-correlative, neuroimaging, MEG, TMS and cortical stimulation studies on nouns and verbs with the aim of assessing the consistency of their results, particularly within techniques. The paper also addresses the question as to whether the inconsistency of the data could be due to the variety of the tasks used. However, it emerged that neither the different investigation techniques used nor the different cognitive tasks employed fully explain the variability of the data. In the final section we thus suggest that the main reason for the emergence of inconsistent data in this field is that the cerebral circuits underlying noun and verb processing are not spatially segregated, at least for the spatial resolution currently used in most neuroimaging studies.     

Recent research on emergent verbal behavior: clinical applications and future directions

This paper describes recent studies that have evaluated the functional independence of verbal operants. Procedures that facilitate the emergence of untrained verbal operants and important areas of future research to increase efficiency of language programs for children diagnosed with developmental disabilities are discussed.     

Independent and interdependent self‐construals: Ramifications for a multicultural society1

Abstract: This study examined American students, Japanese students in Japan, and Japanese students in the USA. First, it examined whether respondents’ scale for independent and interdependent construals of the self (SII) scores would vary depending on the type of relationship (i.e., family members, friends, or peers at the student's university) posited by the instructions. It was found that the SII score of each of the three groups changed depending on the relationship. Second, the relationship between SII scores, perceived conflict, and self‐efficacy were examined. It was found that self‐efficacy was highest among the American students, followed by the Japanese students in the USA, and lowest among the Japanese students in Japan. Self‐efficacy was correlated to independent and interdependent construals of the self. Third, the respondents’ preferences for expressiveness in communication were analyzed. The results of this study showed that there was a difference between the American students and both groups of Japanese students in their preference for three communication styles (independent, mixed, interdependent‐type). Finally, the relationship between intercultural sensitivity, as measured by the intercultural sensitivity inventory, and self‐efficacy were examined. Intercultural sensitivity was shown to have a positive correlation to general self‐efficacy.     

Notes on selective influence, probabilistic causality, and probabilistic dimensionality

The paper provides conceptual clarifications for the issues related to the dependence of jointly distributed systems of random entities on external factors. This includes the theory of selective influence as proposed in Dzhafarov [(2003a). Selective influence through conditional independence. Psychometrika, 68, 7-26] and generalized versions of the notions of probabilistic causality [Suppes, P., & Zanotti, M. (1981). When are probabilistic explanations possible? Synthese, 48, 191-199] and dimensionality in the latent variable models [Levine, M. V. (2003). Dimension in latent variable models. Journal of Mathematical Psychology, 47, 450-466]. One of the basic observations is that any system of random entities whose joint distribution depends on a factor set can be represented by functions of two arguments: a single factor-independent source of randomness and the factor set itself. In the case of random variables (i.e., real-valued random entities endowed with Borel sigma-algebras) the single source of randomness can be chosen to be any random variable with a continuous distribution (e.g., uniformly distributed between 0 and 1).     

Causes of Allais common consequence paradoxes: An experimental dissection

The common consequence paradox of Allais can be decomposed into three simpler principles: transitivity, coalescing, and restricted branch independence. Different theories attribute such paradoxes to violations of restricted branch independence only, to coalescing only, or to both. This study separates tests of these two properties in order to compare these theories. Although rank-dependent utility (RDU) theories, including cumulative prospect theory (CPT), violate branch independence, the empirical pattern of violations is opposite that required by RDU theories to account for Allais paradoxes. Data also show systematic violations of coalescing, which refute RDU theories. The findings contradict both original and CPTs with or without their editing principles of combination and cancellation. Modal choices were well predicted by Birnbaum's RAM and TAX models with parameters estimated from previous data. The effects of event framing on these tests were also assessed and found to be negligible.

Hemispheric specialization and independence for word recognition: a comparison of three computational models

Two findings serve as the hallmark for hemispheric specialization during lateralized lexical decision. First is an overall word advantage, with words being recognized more quickly and accurately than non-words (the effect being stronger in response latency). Second, a right visual field advantage is observed for words, with little or no hemispheric differences in the ability to identify non-words. Several theories have been proposed to account for this difference in word and non-word recognition, some by suggesting dual routes of lexical access and others by incorporating separate, and potentially independent, word and non-word detection mechanisms. We compare three previously proposed cognitive theories of hemispheric interactions (callosal relay, direct access, and cooperative hemispheres) through neural network modeling, with each network incorporating different means of interhemispheric communication. When parameters were varied to simulate left hemisphere specialization for lexical decision, only the cooperative hemispheres model showed both a consistent left hemisphere advantage for word recognition but not non-word recognition, as well as an overall word advantage. These results support the theory that neural representations of words are more strongly established in the left hemisphere through prior learning, despite open communication between the hemispheres during both learning and recall.     

Open questions related to the problem of Birkhoff and Maltsev

The Birkhoff-Maltsev problem asks for a characterization of those lattices each of which is isomorphic to the lattice L(K) of all subquasivarieties for some quasivariety K of algebraic systems. The current status of this problem, which is still open, is discussed. Various unsolved questions that are related to the Birkhoff-Maltsev problem are also considered, including ones that stem from the theory of propositional logics.Special issue of Studia Logica: Algebraic Theory of Quasivarieties Presented by Ryszard Wójcicki     

Conflict of interest in Croatia: doctors with dual obligations

There is an emerging awareness of the possibility of conflicts of interest in the practice of medicine in Croatia. The paper examines areas within the medical profession where conflicts of interest can and have occurred, probably not only in Croatia. Particularly addressed are situations when a doctor may have dual obligations and how independent ethics committees can help in decreasing the influence of a conflict of interest. The paper also presents extracts from the Croatian Code of Ethics for the medical profession that address problems of conflict of interest. An earlier version of this paper entitled was presented at an International Conference on “Conflict of Interest and its Significance in Science and Medicine” held in Warsaw, Poland on 5–6 April, 2002.     

Editorial independence at medical journals owned by professional associations: A survey of editors

The purpose of this study was to assess the degree of editorial independence at a sample of medical journals and the relationship between the journals and their owners. We surveyed the editors of 33 medical journals owned by not-for-profit organizations (“associations”), including 10 journals represented on the International Committee of Medical Journal Editors (nine of which are general medical journals) and a random sample of 23 specialist journals with high impact factors that are indexed by the Institute for Scientific Information. The main outcome measures were the authority to hire, fire, and oversee the work of the editor; the editor’s tenure and financial compensation; control of the journal’s budget; publication of material about the association; and the editor’s perceptions about editorial independence and pressure over editorial content. Of the 33 editors, 23 (70%) reported having complete editorial freedom, and the remainder reported a high level of freedom (a score of ≥8, where 10 equals complete editorial freedom and 1 equals no editorial freedom). Nevertheless, a substantial minority of editors reported having received at least some pressure in recent years over editorial content from the association’s leadership (42%), senior staff (30%), or rank-and-file members (39%). The association’s board of directors has the authority to hire (48%) or fire (55%) the editor for about half of the journals, and the editor reports to the board for 10 journals (30%). Twenty-three editors (70%) are appointed for a specific term (median term =5 years). Three-fifths of the journals have no control over their profit, and the majority of journals use the association’s legal counsel and/or media relations staff. Stronger safeguards are needed to give editors protection against pressure over editorial content, including written guarantees of editorial freedom and governance structures that support those guarantees. Strong safeguards are also needed because editors may have less freedom than they believe (especially if they have not yet tested their freedom in an area of controversy).
