Sensitivity and salience of form–function correlations of objects: Evidence from feature tasks

The present research evaluates the sensitivity and salience of form-function correlations in contrast with other types of feature correlations (function-function, form-form) in adults and using real object features (from tools and utensils). In Experiment 1, the participants judged the relation between the form and function features of tools. In Experiment 2, participants were asked to generate a second feature related to a given form or function feature. In Experiment 3, participants were asked to make a lexical decision in which form and function features were used as primes and targets. The results showed that even though participants were sensitive to form-function correlations, these were not particularly salient when compared with other feature-type correlations, notably function-function correlations. Our data underline the overall importance of function information to object representations and the impact of the statistical co-occurrence of features when processing object features.     

Language nonselective access to phonological representations: Evidence from Chinese–English bilinguals

Four experiments with Chinese–English bilinguals were conducted in order to investigate the hypothesis of language nonselective access to an integrated lexicon for bilingual phonological representations. Results of a naming task (in Experiments 1 and 2) and a lexical decision task (in Experiments 3 and 4) showed homophone priming effects regardless of priming direction (English to Chinese, or Chinese to English) or English proficiency. Our findings are compatible with the BIA+ model of bilingual processing, provide further support for the hypothesis of language nonselective access to an integrated lexicon for bilingual phonological representations, and extend the hypothesis to language pairs with very different writing systems.     

Attention,competition, and the parietal lobes: insights from Balint’s syndrome

Simultanagnosia (resulting from occipito-parietal damage) is a profound visual deficit, which impairs the ability to perceive multiple items in a visual display, while preserving the ability to recognise single objects. Here we demonstrate in a patient presenting with Balint’s syndrome that this deficit may result from an extreme form of competition between objects which makes it difficult for attention to be disengaged from an object once it has been selected.     

Mother–child relationship quality from preschool to adolescence: Variation by maternal education

Using longitudinal data from the National Institute of Child Health and Human Development Study of Early Child Care and Youth Development (N = 1088), we examine changes in maternal perception of closeness and conflict in the mother–child relationship from the child's preschool to adolescent years, with attention to variation by maternal education. Analyses using individual growth models show that mother–child closeness increases, while mother–child conflict decreases, from preschool to first grade. From first grade to age 15, mother–child closeness decreases, while mother–child conflict increases, both gradually. The decrease in mother–child conflict from preschool to first grade and the increases in mother–child conflict from first to fifth grade, sixth grade, and age 15 are less steep for mothers with a college degree than for mothers without a college degree. These findings underscore the importance of examining changes in parent–child relationships using longitudinal data across children's developmental stages and their variations by parental social and economic status.     

Opposition from Christians to Myers–Briggs personality typing: an analysis and evaluation

Myers–Briggs personality typing is widely used in the Christian church as an aid to individual self‐understanding and spiritual formation. However, some Christian leaders have expressed doubt about its validity in understanding human personality and also opposition to its use in nurturing spiritual growth. The aim of the work reported was to identify and examine the reasons for this negative stance towards personality typing. It was achieved by content analysis of published writings and, in a few cases, by correspondence with persons known to have a critical stance. The analysis showed five principal areas of concern: misuse of personality typing in spiritual formation; personality typing as a simplistic analysis; personality typing as a restrictive pigeon‐holing; unethical use of personality typing; and the Jungian derivation of personality type theory. Evaluation of this unease reveals significant semantic and epistemological issues and also a concern that personality typing, while not denying the tenets of Christian belief, could rival them for primacy in the hearts and minds of Christians.     

Transition from the Bose–Einstein condensate to the Berezinskii–Kosterlitz–Thouless phase

We obtain a phase diagram for a trapped two-dimensional ultracold Bose gas. We find a critical temperature above which the free energy of a state with a pair of vortices of opposite circulation is lower than that for a vortex-free Bose–Einstein condensed ground state. We identify three distinct phases which are, in order of increasing temperature, a phase coherent Bose–Einstein condensate, a vortex pair plasma with a fluctuating condensate phase, and a thermal Bose gas. The existence of the vortex pair phase could be verified using current experimental set-ups.     

Prefrontal cortex dysfunction and ‘Jumping to Conclusions’: Bias or deficit?

The 'beads task' is used to measure the cognitive basis of delusions, namely the 'Jumping to Conclusions' (JTC) reasoning bias. However, it is not clear whether the task merely taps executive dysfunction - known to be impaired in patients with schizophrenia - such as planning and resistance to impulse. To study this, 19 individuals with neurosurgical excisions to the prefrontal cortex, 21 unmedicated adults with Attention Deficit Hyperactivity Disorder (ADHD), and 25 healthy controls completed two conditions of the beads task, in addition to tests of memory and executive function as well as control tests of probabilistic reasoning ability. The results indicated that the prefrontal lobe group (in particular, those with left-sided lesions) demonstrated a JTC bias relative to the ADHD and control groups. Further exploratory analyses indicated that JTC on the beads task was associated with poorer performance in certain executive domains. The results are discussed in terms of the executive demands of the beads task and possible implications for the model of psychotic delusions based on the JTC bias.     

Completeness: from Gödel to Henkin

This paper focuses on the evolution of the notion of completeness in contemporary logic. We discuss the differences between the notions of completeness of a theory, the completeness of a calculus, and the completeness of a logic in the light of Gödel's and Tarski's crucial contributions.We place special emphasis on understanding the differences in how these concepts were used then and now, as well as on the role they play in logic. Nevertheless, we can still observe a certain ambiguity in the use of the close notions of completeness of a calculus and completeness of a logic. We analyze the state of the art under which Gödel's proof of completeness was developed, particularly when dealing with the decision problem for first-order logic. We believe that Gödel had to face the following dilemma: either semantics is decidable, in which case the completeness of the logic is trivial or, completeness is a critical property but in this case it cannot be obtained as a corollary of a previous decidability result. As far as first-order logic is concerned, our thesis is that the contemporary understanding of completeness of a calculus was born as a generalization of the concept of completeness of a theory. The last part of this study is devoted to Henkin's work concerning the generalization of his completeness proof to any logic from his initial work in type theory.     

Patriotism: from Twardowski to Bocheński

In my paper, I show three concepts of patriotism present in the Lvov-Warsaw School, and try to indicate how these concepts differed and what norms they were involved in, as well as to evaluate the justifications indicated for these norms.

     

The evolution of foresight: What is mental time travel, and is it unique to humans?

In a dynamic world, mechanisms allowing prediction of future situations can provide a selective advantage. We suggest that memory systems differ in the degree of flexibility they offer for anticipatory behavior and put forward a corresponding taxonomy of prospection. The adaptive advantage of any memory system can only lie in what it contributes for future survival. The most flexible is episodic memory, which we suggest is part of a more general faculty of mental time travel that allows us not only to go back in time, but also to foresee, plan, and shape virtually any specific future event. We review comparative studies and find that, in spite of increased research in the area, there is as yet no convincing evidence for mental time travel in nonhuman animals. We submit that mental time travel is not an encapsulated cognitive system, but instead comprises several subsidiary mechanisms. A theater metaphor serves as an analogy for the kind of mechanisms required for effective mental time travel. We propose that future research should consider these mechanisms in addition to direct evidence of future-directed action. We maintain that the emergence of mental time travel in evolution was a crucial step towards our current success.     

Surprise influences hindsight–foresight differences in temporal judgments of animated automobile accidents

The hindsight bias occurs when people view an outcome as more foreseeable than it actually was. The role of an outcome’s initial surprise in the hindsight bias was examined using animations of automobile accidents. Twenty-six participants rated the initial surprise of accidents’ occurring in eight animations. An additional 84 participants viewed these animations in one of two conditions: Half stopped the animations when they were certain an accident would occur (i.e., in foresight), and the other half watched the entire animations first and then stopped the animations when they thought that a naïve viewer would be certain that an accident would occur (i.e., in hindsight). When the accidents were low in initial surprise, there were no foresight–hindsight differences; when initial surprise was medium, there was a hindsight bias; and when initial surprise was high, there was a reversed hindsight bias. The results are consistent with a sense-making model of hindsight bias.

From fringe to fringe: the shift from the clericalist League of Polish Families to the anticlericalist Palikot Movement 2001–2015

The period between 2001 and 2015 brought two events in Poland that deserve to be called phenomena. In 2001 the rightist, clericalist League of Polish Families entered the Sejm. Ten years later, the leftist, anticlericalist Palikot Movement achieved spectacular success in the 2011 elections. These events give a picture of a radical shift in the Polish political scene: a rightist clericalist party disappeared from the right flank of the political scene, while a new, leftist-anticlericalist formation appeared. The article makes reference to a set of five explanations on both the causes and consequences (and permanence) of the observed changes. I argue that only a concurrence of a number of complementary factors – global (secularisation, right-wing populism, postmodernism); structural (changing patterns of rivalry between Polish political parties); and periodic (critical events) – allows us to explain both the radical shift in ‘religious’ voting and the success of politically extreme parties. In total, these conditions make up an ‘opportunity structure’ within which only a set of mutually conditioning factors can bring about such a critical shift.

Resistance to extinction: a measure of orbitofrontal function suitable for children?

Extinction of operantly conditioned responses, which provides a measure of the ability to adapt to changes in the reinforcement value of stimuli, has been linked to orbitofrontal cortex (OFC) in human and non-human animals. This article examines the feasibility of using extinction as a measure of the development of OFC function in preschool-age children. If extinction serves as a measure of OFC function, resistance to extinction should decrease during this age range. In Part 1, we review the literature on extinction as related to OFC, and summarize what is known regarding age-related changes in extinction in young children. In Part 2, we report results of a study assessing extinction in children between 3 and 6 years of age. Results revealed age-related increases in responding during extinction, with girls (particularly, 6-year-old girls) exhibiting stronger resistance to extinction. Some relations were found with temperament and normative compulsive-like behavior. The findings of this study question the utility of extinction of operant responding as a measure of OFC function in young children.     

Personal selling and the purchasing function: where do we go from here?

The business-to-business selling function has changed over the years, with more informed and demanding buyers, prompting firms to move toward a more consultative, solution-selling approach. While these changes have been the focus of extensive research in the personal selling and sales management domain, the customer side of the interaction dyad requires more examination. Even within the context of the customer side, insufficient attention has been paid to the purchasing function in business-to-business (B2B) selling research. Given the increased importance in customer organizations of the purchasing function, this article presents a literature review that highlights the purchasing function's personal selling and sales management needs and argues that, as the purchasing function becomes more important and its needs evolve, personal selling and sales strategies also need to evolve. The article highlights areas for future research in this domain.     

Posterior parietal cortex: An interface between attention and learning?

The posterior parietal cortex (PPC) of rats has most recently been defined based on patterns of thalamic and cortical connectivity. The anatomical characteristics of this area suggest that it may be homologous to the PPC of primates and contribute to similar functions. This review summarizes evidence for and against a role for the rat PPC in attention and working memory and evaluates how the function of the rat PPC compares to that of primates on these dimensions. Theories of how the rat PPC contributes to behavior are presented, including the notion that PPC may serve as an interface between attention and learning. Finally, several avenues for future research are considered.
