Functioning of cognitive codes in autobiographical memory and the self—Is the self visual?

The main goal was to test the relationship between types of cognitive codes (perceptual–imaginative and verbal–propositional) and autobiographical memory. The purpose of this research was to evaluate whether there are independent processes serving the self, depending on separate cognitive codes. Sixty adult participants completed the NEO-FFI inventory using two kinds of procedure: perceptual–imaginative code or verbal–propositional code. Both quantitative and qualitative methods were used for analysis. The study has shown the dynamic of the self, depending on two cognitive perspectives. The results indicate that the reflection of the self in autobiographical memory brings different knowledge about the self and its motives.     

A Study in Grzegorczyk Point-Free Topology Part I: Separation and Grzegorczyk Structures

This is the first, out of two papers, devoted to Andrzej Grzegorczyk’s point-free system of topology from Grzegorczyk (Synthese 12(2–3):228–235, 1960.  https://doi.org/10.1007/BF00485101). His system was one of the very first fully fledged axiomatizations of topology based on the notions of region, parthood and separation (the dual notion of connection). Its peculiar and interesting feature is the definition of point, whose intention is to grasp our geometrical intuitions of points as systems of shrinking regions of space. In this part we analyze (quasi-)separation structures and Grzegorczyk structures, and establish their properties which will be useful in the sequel. We prove that in the class of Urysohn spaces with countable chain condition, to every topologically interpreted representative of a point in the sense of Grzegorczyk’s corresponds exactly one point of a space. We also demonstrate that Tychonoff first-countable spaces give rise to complete Grzegorczyk structures. The results established below will be used in the second part devoted to points and topological spaces.     

On Modality Effects in Bilingual Emotional Language Processing: Evidence from Galvanic Skin Response

Though previous research has shown a decreased sensitivity to emotionally-laden linguistic stimuli presented in the non-native (L2) compared to the native language (L1), studies conducted thus far have not examined how different modalities influence bilingual emotional language processing. The present experiment was therefore aimed at investigating how late proficient Polish (L1)–English (L2) bilinguals process emotionally-laden narratives presented in L1 and L2, in the visual and auditory modality. To this aim, we employed the galvanic skin response (GSR) method and a self-report measure (Polish adaptation of the PANAS questionnaire). The GSR findings showed a reduced galvanic skin response to L2 relative to L1, thus suggesting a decreased reactivity to emotional stimuli in L2. Additionally, we observed a more pronounced skin conductance level to visual than auditory stimuli, yet only in L1, which might be accounted for by a self-reference effect that may have been modulated by both language and modality.     

Power boosts reliance on preferred processing styles

A significant amount of research has proposed that power leads to heuristic and category based information processing, however, the evidence is often contradictory. We propose the novel idea that power magnifies chronically accessible information processing styles which can contribute to either systematic or heuristic processing. We examine heuristic (vs. systematic) processing in association with the need for closure. The results of three studies and a meta-analysis supported these claims. Power increased heuristic information processing, manifested in the recognition of schema consistent information, in the use of stereotypical information to form impressions and decreased the complexity of categorical representations, but only for those participants who, by default, processed information according to simplified heuristics, i.e., are high in need for closure. For those who prefer this processing style less, i.e., low in need for closure, power led to the opposite effects. These findings suggest that power licenses individuals to rely on their dominant information processing strategies, and that power increases interpersonal variability.     

The bilingual brain turns a blind eye to negative statements in the second language

Neurobilingualism research has failed to reveal significant language differences in the processing of affective content. However, the evidence to date derives mostly from studies in which affective stimuli are presented out of context, which is unnatural and fails to capture the complexity of everyday sentence-based communication. Here we investigated semantic integration of affectively salient stimuli in sentential context in the first- and second-language (L2) of late fluent Polish–English bilinguals living in the UK. The 19 participants indicated whether Polish and English sentences ending with a semantically and affectively congruent or incongruent adjective of controlled affective valence made sense while undergoing behavioral and electrophysiological recordings. We focused on the N400, a wave of event-related potentials known to index semantic integration. We expected N400 amplitude to index increased processing demands in L2 English comprehension and potential language–valence interactions to reveal differences in affective processing between languages. Contrary to our initial expectation, we found increased N400 for sentences in L1 Polish, possibly driven by greater affective salience of sentences in the native language. Critically, language interacted with affective valence, such that N400 amplitudes were reduced for English sentences ending in a negative fashion as compared to all other conditions. We interpreted this as a sign that bilinguals suppress L2 content embedded in naturalistic L2 sentences when it has negative valence, thus extending the findings of previous research on single words in clinical and linguistic research.     

Distributed Knowability and Fitch’s Paradox

Recently predominant forms of anti-realism claim that all truths are knowable. We argue that in a logical explanation of the notion of knowability more attention should be paid to its epistemic part. Especially very useful in such explanation are notions of group knowledge. In this paper we examine mainly the notion of distributed knowability and show its effectiveness in the case of Fitch’s paradox. Proposed approach raised some philosophical questions to which we try to find responses. We also show how we can combine our point of view on Fitch’s paradox with the others. Next we give an answer to the question: is distributed knowability factive? At the end, we present some details concerning a construction of anti-realist modal epistemic logic.     

Internalisation of Relations

How useful are corpus-based methods for extrapolating psycholinguistic variables?

Subjective ratings for age of acquisition, concreteness, affective valence, and many other variables are an important element of psycholinguistic research. However, even for well-studied languages, ratings usually cover just a small part of the vocabulary. A possible solution involves using corpora to build a semantic similarity space and to apply machine learning techniques to extrapolate existing ratings to previously unrated words. We conduct a systematic comparison of two extrapolation techniques: k-nearest neighbours, and random forest, in combination with semantic spaces built using latent semantic analysis, topic model, a hyperspace analogue to language (HAL)-like model, and a skip-gram model. A variant of the k-nearest neighbours method used with skip-gram word vectors gives the most accurate predictions but the random forest method has an advantage of being able to easily incorporate additional predictors. We evaluate the usefulness of the methods by exploring how much of the human performance in a lexical decision task can be explained by extrapolated ratings for age of acquisition and how precisely we can assign words to discrete categories based on extrapolated ratings. We find that at least some of the extrapolation methods may introduce artefacts to the data and produce results that could lead to different conclusions that would be reached based on the human ratings. From a practical point of view, the usefulness of ratings extrapolated with the described methods may be limited.     

Consumer acceptance of innovations in food: A survey among Polish consumers

The aim of the study was to examine the possible factors that might contribute to consumer acceptance of food innovations. Particular attention was paid to 3 main factors: (a) relationship between socio‐demographic determinants and level of consumer innovation, (b) evaluation of consumer innovation acceptance, particularly toward animal‐derived food products, and (c) consumer preferences for health‐promoting food innovation over time. Studies were conducted using quantitative research methods in 2004 and 2011. An organic method of production, least important in 2004, was top rated in 2011, and ease of preparation dropped to the bottom of the list in 2011, whereas food origin, low fat, and sugar content were ranked in the first group of the considered factors in 2011. Since 2004, consumers have become used to products with various innovations. The new generation of Poles is relatively more open to new food products, due to the wide range of food products available on the free market. Furthermore, the group of well‐educated consumers with a higher level of income has increased in size, and this includes people interested in knowledge of a product's nutritional value and its health impact. Our study extends existing research in the area of understanding consumer expectations toward food innovations. The results not only contribute to the field of consumer behavior but also have practical potential for food market applications, especially for companies operating on or planning to enter the Polish food market, and which could be used for developing communication strategies.     

Dissociable contributions of the left and right posterior medial orbitofrontal cortex in motivational control of goal-directed behavior

Several findings from both human neuroimaging and nonhuman primate studies suggest that the posterior medial orbitofrontal cortex (OFC) may be critical for the motivational control of goal-directed behavior. The present study was conducted to clarify the role of the left and right posterior medial OFC in that function by examining the effects of focal unilateral lesions to this region on the performance on an incentive working memory task. The study covered patients who had undergone surgery for an ACoA aneurysm and normal control subjects (C). The patients were subdivided into three groups: those with resection of the left (LGR+) or right (RGR+) posterior part of the gyrus rectus, and without such a resection (GR−). Participants performed a 2-back working memory task under three motivational conditions (penalty, reward, and no-incentive). The C group performed worse in the penalty condition and better in the reward condition as compared to the no-incentive condition. Similar results were obtained for the GR− group. Performance of the LGR+ group did not depend on incentive manipulations, whereas the RGR+ group performed better in both the penalty and reward conditions than in the no-incentive condition. The results show that the posterior medial OFC is involved in the motivational modulation of working memory performance. Our findings also suggest that the left posterior medial OFC plays a crucial role in this function, whereas the right posterior medial OFC is particularly involved in the processing of the punishing aspect of salient events and it probably mediates in guiding behavior on the basis of negative outcomes of action.
