A Picture Database for Verbs and Nouns with Different Action Content in Turkish

In this study we present a picture database of 160 nouns and 160 verbs. All verbs and nouns are divided into two groups as action and non-action words. Age of acquisition, familiarity, imageability, name agreement and complexity norms are reported alongside frequency, word length and morpheme count for each word. Data were collected from 600 native Turkish adults in total. The results show that although several measures have weak correlations with each other, only age of acquisition had moderate downhill relationships with familiarity and frequency with familiarity and frequency having a rather strong positive correlation with each other. The norms and the picture database are available as supplemental materials for use in psycholinguistic studies in Turkish.     

A Meta-Analysis of Working Memory Impairments in Autism Spectrum Disorders

Autism spectrum disorders (ASD) are characterized by executive dysfunction, and working memory (WM) comprises one core component of executive function. Many studies have investigated WM impairments in individuals with ASD, however, a conclusive agreement has not been reached. The present study provided a meta-analytic review of WM impairments in individuals with ASD and evaluated potential moderating variables of this problem. Twenty-eight studies were included in this study, and the participants comprised 819 individuals with ASD and 875 healthy controls. A significant WM impairment (Cohen’s d?=??0.61) was identified in the individuals with ASD, however, this impairment was not associated with age. Results of moderation analyses showed that (a) spatial WM was more severely impaired than verbal WM and (b) the component of cognitive processing (maintenance vs. maintenance plus manipulation) did not affect the severity of WM impairments. These findings suggest that WM is impaired in individuals with ASD and may have implications for interventions related to WM impairments in these individuals.     

Decoding dyadic interactive nonverbal behaviour in Chinese and Australian cohorts: A novel dyadic puzzle‐solving task

The current study used a novel problem‐solving task in which the solution could only be reached via interactions between members of dyads. The study aimed to systematically examine how nonverbal interactive behaviour was related to the cultural background of the dyads, the participant's role in the dyad (viz., instructor, problem solver) and task repetition. Twenty‐one Australian dyads and 32 Chinese dyads performed the dyadic puzzle‐solving task while their interactions were video‐recorded. In each dyad, one instructor and one problem solver worked together to solve a seven‐piece puzzle. Six trials, each comprising a different puzzle, were completed. Results indicate that the Australian instructors engaged in significantly more eye gazing and displayed more hand gestures but smiled less than the Chinese instructors. The Australian problem solvers maintained longer eye gazing, displayed more hand gestures and more echoing than their Chinese counterparts. Over trials, the Chinese instructors reduced their total talking time, hand gestures, nodding behaviour and smiling during self‐talking more than the Australian instructors. Moreover, the problem solvers in the dyads from both countries significantly reduced their smiling across trials. The current study shows that nonverbal behaviours during dyadic interactions are related to one's cultural background, role in the task and task repetition.     

Drifting Here and There But Going Nowhere: the Case of Migrants from Turkey in Milan in the Era of Global Economic Crisis

This paper argues that migration is becoming a protracted situation for the significant part of migrants in parallel to the deepening world economic crisis. Migrants keep drifting from one place to another in the face of future uncertainties. The paper analyses the protracted feature of migration, which is becoming increasingly salient through a new conceptualization, and links it with the world economic crisis and capital accumulation processes. The argument is supported by the data obtained from a field research implemented in Milan, Italy, in 2013 on migrants from Turkey. The Italian economy went into deep recession in 2009 when it was overlapped by a worldwide economic crisis. This situation led migrant workers to lose their jobs. Hence, self-employment of some Turkish migrants was directly related to the deepening economic crisis. Not only comparatively new Turkish migrants but also migrants who spent some years in Milan cannot see a secure future in there and think of migrating yet again.     

Using support vector machines to identify literacy skills: Evidence from eye movements

Is inferring readers’ literacy skills possible by analyzing their eye movements during text reading? This study used Support Vector Machines (SVM) to analyze eye movement data from 61 undergraduate students who read a multiple-paragraph, multiple-topic expository text. Forward fixation time, first-pass rereading time, second-pass fixation time, and regression path reading time on different regions of the text were provided as features. The SVM classification algorithm assisted in distinguishing high-literacy-skilled readers from low-literacy-skilled readers with 80.3 % accuracy. Results demonstrate the effectiveness of combining eye tracking and machine learning techniques to detect readers with low literacy skills, and suggest that such approaches can be potentially used in predicting other cognitive abilities.     

刺激前负波:奖赏期待的电生理指标

刺激前负波(Stimulus-Preceding Negativity,SPN)是从关联性负变化中分离出来的非运动性慢电位,其波幅随着反馈刺激的临近逐渐升高。先前研究侧重于将SPN视为一种认知性成分,而最近的研究支持了SPN是奖赏期待的可靠指标。本文从奖赏的基本属性、结果评价、神经发生源以及特殊人群等角度,对SPN反映奖赏期待这一假说进行了梳理,并提出了未来的研究方向,旨在为研究奖赏期待受损的神经精神类疾病提供可靠的生物学标记。     

Self awareness and the body image

What mental representations give us the sense of our body as a unique object in the world? We investigated this issue in the context of the rubber hand illusion (RHI), an illusion of body image in which a prosthetic hand brushed synchronously, but not asynchronously, with one’s own hand is perceived as actually being one’s hand. We conducted a large-scale study of the RHI, and used psychometric analysis to reveal the structure of the subjective experience of embodiment [Longo et al. (2008). What is embodiment? A psychometric approach. Cognition,107, 978-998]. Here, we use this dataset to investigate the relation between incorporation of a rubber hand into the body image and the perceived similarity between the participant’s hand and the rubber hand. Objective similarity (as measured by skin luminance, hand shape, and third-person similarity ratings) did not appear to influence participants’ experience of the RHI. Conversely, incorporation of the rubber hand into the body image did affect the similarity that participants perceived between their own hand and the rubber hand. Participants who had experienced the RHI perceived their hand and the rubber hand as significantly more similar than participants who had not experienced the illusion. That is, embodiment leads to perceived similarity, but perceived similarity does not lead to embodiment. Furthermore, similarity ratings following the illusion were selectively correlated with some components of embodiment, but not with others. These results suggest an important role of a mental body image in the perception of the relation between the self and others.     

De la prévention à la promotion de la santé : intérêt de l’approche communautaire

Psychological research and practice shows increasing interest for prevention and health promotion in France. Current-scientific literature recommends the implementation of targeted actions, directed towards populations expressing specific needs. The community-based approach offers a framework corresponding to the flexibility, which is necessary to the effectiveness of this type of intervention. It includes the mobilization and the participation of the citizens in the development of each unique project, in the renewal of the project according to the needs, in finding possible solutions, and in assessing the actions carried out. This article aims at presenting the importance of a community-based approach in the field of health promotion; a field which would benefit from being better known in France in order to develop intervention programs adapted to each population.     

On L-decomposability of random orderings

In the setting of random orderings, we study conditional independence properties related to L-decomposability. We show that if a random ordering satisfies L-decomposability for any labelling of the ranks, then it is quasi-independent, provided the number of alternatives is at least 4, and each ordering has a positive probability.
