Innovative behaviour in fish: Atlantic cod can learn to use an external tag to manipulate a self-feeder

This study describes how three individual fish, Atlantic cod (Gadus morhua L.), developed a novel behaviour and learnt to use a dorsally attached external tag to activate a self-feeder. This behaviour was repeated up to several hundred times, and over time these fish fine-tuned the behaviour and made a series of goal-directed coordinated movements needed to attach the feeder’s pull string to the tag and stretch the string until the feeder was activated. These observations demonstrate a capacity in cod to develop a novel behaviour utilizing an attached tag as a tool to achieve a goal. This may be seen as one of the very few observed examples of innovation and tool use in fish.     

Do Attitudes Towards the Integration of Immigrants Change Over Time? A Comparative Study of Natives,Second-Generation Immigrants and Foreign-Born Residents in Luxembourg

The aim of this paper is to investigate attitudes toward the integration of immigrants in Luxembourg—the country with the highest proportion of immigrants in Europe. First, the paper examines how attitudes toward integration (consisting of two dimensions: attitudes toward assimilation and attitudes toward multiculturalism) vary among different groups of the country’s residents, i.e. natives and residents with a migratory background. Second, it examines how these attitudes have evolved over a period of nearly ten years. The Luxembourgish European Value Study data from 1999 and 2008 are used. The results of the analyses reveal that attitudes towards the integration of immigrants differ significantly among the resident groups analysed. Native residents are more supportive of the assimilation model compared to foreign-born residents and second-generation immigrants with two foreign-born parents, whereas the latter groups score higher on the multiculturalism scale than the other groups. With respect to trends in attitudes towards integration, the assimilation model gained popularity between 1999 and 2008 among all groups, whereas only a small decrease in popularity was found with respect to preferences for multicultural integration.     

Effects of negative content on the processing of gender information: An event-related potential study

Previous research on emotion in language has mainly concerned the impact of emotional information on several aspects of lexico-semantic analyses of single words. However, affective influences on morphosyntactic processing are less understood. In the present study, we focused on the impact of negative valence in the processing of gender agreement relations. Event-related potentials (ERPs) were recorded while participants read three-word phrases and performed a syntactic judgment task. Negative and neutral adjectives could agree or disagree in gender with the preceding noun. At an electrophysiological level, the amplitude of a left anterior negativity (LAN) to gender agreement mismatches decreased in negative words, relative to neutral words. The behavioral data suggested that LAN amplitudes might be indexing the processing costs associated with the detection of gender agreement errors, since the detection of gender mismatches resulted in faster and more accurate responses than did the detection of correct gender agreement relations. According to this view, it seems that negative content facilitated the processes implicated in the early detection of gender agreement mismatches. However, gender agreement violations in negative words triggered processes involved in the reanalysis and repair of the syntactic structure, as reflected in larger P600 amplitudes to incorrect than to correct phrases, irrespective of their emotional valence.     

Dissociable yet tied inhibitory processes: The structure of inhibitory control

Cognitive and neural models have proposed the existence of a single inhibitory process that regulates behavior and depends on the right frontal operculum (rFO). The aim of this study was to make a contribution to the ongoing debate as to whether inhibition is a single process or is composed of multiple, independent processes. Here, within a single paradigm, we assessed the links between two inhibitory phenomena—namely, resistance to involuntary visual capture by abrupt onsets and resolving of spatial stimulus–response conflict. We did so by conducting three experiments, two involving healthy volunteers (Exps. 1 and 3), and one with the help of a well-documented patient, R.J., with selectively weakened inhibition following a lesion of the rFO. The results suggest that resistance to capture and stimulus–response conflict are independent, because (a) additive effects were found (Exps. 1 and 3), (b) capture did not correlate with compatibility effects (Exp. 1), (c) dual tasking affected the two phenomena differently (Exp. 3), and (d) a dissociation was found between the two in patient R.J. (Exp. 2). However, the results also show that these two phenomena may share some processing components, given that (a) both were affected in patient R.J., but to different degrees (Exp. 2), and (b) increasing the difficulty of dual tasking produced an increasingly negative correlation between capture and compatibility (Exp. 3), which suggests that when resources are withdrawn from the control of the former, they are used to control the latter.     

Global self-esteem and method effects: Competing factor structures,longitudinal invariance,and response styles in adolescents

The Rosenberg Self-Esteem Scale (RSES) is a widely used measure for assessing self-esteem, but its factor structure is debated. Our goals were to compare 10 alternative models for the RSES and to quantify and predict the method effects. This sample involves two waves (N =2,513 9th-grade and 2,370 10th-grade students) from five waves of a school-based longitudinal study. The RSES was administered in each wave. The global self-esteem factor with two latent method factors yielded the best fit to the data. The global factor explained a large amount of the common variance (61% and 46%); however, a relatively large proportion of the common variance was attributed to the negative method factor (34 % and 41%), and a small proportion of the common variance was explained by the positive method factor (5% and 13%). We conceptualized the method effect as a response style and found that being a girl and having a higher number of depressive symptoms were associated with both low self-esteem and negative response style, as measured by the negative method factor. Our study supported the one global self-esteem construct and quantified the method effects in adolescents.     

The embodied nature of medical concepts: image schemas and language for pain

Cognitive linguistics assumes that knowledge is both embodied and situated as far as it is acquired through our bodily interaction with the world in a specific environment (e.g. Barsalou in Lang Cogn Process 18:513–562, 2003; Connell et al. in PLoS One 7:3, 2012). Therefore, embodiment provides an explanation to the mental representation and linguistic expression of concepts. Among the first, we find multimodal conceptual structures, like image schemas, which are schematic representations of embodied experiences resulting from our conceptualization of the surrounding environment (Tercedor Sánchez et al. in J Spec Transl 18:187–205, 2012). Furthermore, the way we interact with the environment and its objects is dynamic and configures how we refer to concepts both by means of images and lexicalizations. In this article, we investigate how image schemas underlie verbal and visual representations. They both evoke concepts based on exteroception, interoception and proprioception which can be lexicalized through language. More specifically, we study (1) a multimodal corpus of medical texts to examine how image schemas lexicalize in the language of medicine to represent specialized concepts and (2) medical pictures to explore the depiction of image-schematic concepts, in order to account for the verbal and visual representation of embodied concepts. We explore the concept pain, a sensory and emotional experience associated with actual or potential tissue damage, using corpus analysis tools (Sketch Engine) to extract information about the lexicalization of underlying image schemas in definitions and defining contexts. Then, we use the image schemas behind medical concepts to consistently select images which depict our experience of pain and the way we understand it. Finally, such lexicalizations and visualizations will help us assess how we refer to pain both verbally and visually.     

Romantic Bonds,Binds, and Ruptures: Couples on the Brink

“Bill and Jane,” a couple I saw many years ago, are placeholders for all the anguished, angry, exhausting, and poignant partners who have made their mark on my work as a clinician and theorist. They inspired and defeated me in equal measure, and they ground this essay, which attempts to bring together many of the theories I have fallen in love with over the years. Psychoanalysis, feminist theory, and systems theory, of course, but also developmental and attachment theory, Fonagy’s work on mentalization, the strategic family therapies, and containing all of these, the relational turn. I have tried to capture the intellectual synergy of putting all these discourses to work, and to work on each other, all of which is necessary when treating couples on the brink.     

Evaluation of a Heredofamilial Cancer Unit in Increasing Family History Collection and Genetic Counseling Referrals Among Spanish Oncologists at a University Hospital

A comprehensive family history is essential to identify patients at risk for hereditary cancer who could benefit from genetic counseling (GC). In a previous study, we observed a low occurrence of family history record (FHR) collection rate and GC referral among oncologists at our institution. The present work analyzes whether the implementation of a heredofamilial cancer unit (HFCU) would improve these parameters. We retrospectively compared the FHR rate in clinical records, National Cancer Institute (NCI) general criteria for hereditary cancer suspicion, GC referrals and FHR quality in two cohorts: cohort 1 (patients diagnosed before HFCU creation) and cohort 2 (after HFCU creation). Of 1,175 patients (590 cohort 1 and 585 cohort 2), FHRs were consigned in 27.3 % and 52.5 % of patients, respectively (p?<?0.001). The GC referral of patients with any NCI criterion was 13.6 % xin cohort 1 vs. 40.5 % in cohort 2 (p?<?0.001). FHR quality improved in terms of the total number of relatives (164 vs. 314, p?=?0.1, N.S.) and number of healthy relatives consigned (80 vs. 191, p?<?0.01). Nine mutations (6 BRCA, 1 MEN1, 2 Lynch), 4 unknown significance variants (all in BRCA) and 2 with no mutation were identified among patients referred from cohort 2. We conclude that the creation of a heredofamilial cancer unit has changed both FHR and GC referrals among oncologists at our institution, although continuous educational efforts are required.     

Temperament and Personal Wellbeing in a Sample of 12 to 16 Year-Old Adolescents

Working on the basis that temperament – understood as the root from which personality traits emerge – is related to subjective wellbeing, a study was conducted on a sample of 1.483 students in compulsory secondary education aged between 12 and 16, half of whom attended schools in a rural or semiurban area and half in an urban setting. The aims of the study were as follows: a) to determine the level of personal wellbeing in a sample of 12 to 16 year-old adolescents measured using scores obtained from the Personal Wellbeing Index (PWI), and b) to analyse the relationship between temperament, measured using the Early Adolescent Temperament Questionnaire (EATQ-R), and personal wellbeing. Results indicate, among other things, that those temperament dimensions which best predict a high level of personal wellbeing are activity level, affiliation, shyness (with a negative weight), inhibitory control and activation control.
