There are conflicting results as to whether preschool children categorize artifacts on the basis of physical or functional similarity. The present study investigated the effect of the relative distinctiveness of these dimensions in children's categorization. In a physical-distinctive condition, preschool children and adults were initially asked to categorize computer-animated artifacts whose physical appearances were more distinctive than their functions. In a function-distinctive condition, the functional dimension of objects was more distinctive than their physical appearances. Both conditions included a second stage of categorization in which both dimensions were equally distinctive. Participants in a control condition performed only this stage of categorization. Adults in all conditions and stages consistently categorized by functional similarity. In contrast, children's categorization was affected by the relative distinctiveness of the dimensions. Children may not have a priori specific beliefs about how to categorize novel artifacts, and thus may be more susceptible to contextual factors.

Although ego-centered network data provide information that is limited in various ways as compared with full network data, an ego-centered design can be used without the need for a priori and researcher-defined network borders. Moreover, ego-centered network data can be obtained with traditional survey methods. However, due to the dynamic structure of the questionnaires involved, a great effort is required on the part of either respondents (with self-administration) or interviewers (with face-to-face interviews). As an alternative, we will show the advantages of using CASI (computer-assisted self-administered interview) methods for the collection of ego-centered network data as applied in a study on the role of social networks in substance use among college students.

In the presented study, the authors raise the question of the need to include in the educational process of a preschool institution to familiarize children with some philosophical categories. The educational system in which the child is included, starting from preschool childhood, provides him with the opportunity to gradually and continuously enter the knowledge of the world around him. It is in preschool childhood that the child is exposed to various relationships, values of culture and health, diverse patterns in the field of different knowledge. This contributes to a broader interaction of the preschooler with the world around him, which, in turn, ensures the assimilation not of disparate ideas about objects and phenomena, but their natural integration and interpenetration, which means understanding the integrity of the picture of the world. The authors prove the idea that the assimilation of philosophical categories by children contributes to the understanding of the structure of the surrounding world. The analysis of research is presented, proving that children's fiction in an understandable and accessible language, life examples and vivid images is able to explain to children the laws of the functioning of nature and society, as well as to reveal the world of human relations and feelings. Fiction surrounds the child from the first years of his life. It is she who contributes to the development of thinking and imagination, enriches the sensory world, provides role models and teaches you to find a way out in different situations. Philosophical categories such as "love and friendship", "beautiful and ugly", "good and evil" are represented in children's literature very widely, and the efficiency of mastering philosophical categories depends on the skill of an adult in conveying the content of a work, on correctly placed accents.

The Impact

This book provides an account of how and why routine interactions break down and how such situational breakdowns lead to protest violence and other types of surprising social outcomes. It takes a close-up look at the dynamic processes of how situations unfold and compares their role to that of motivations, strategies, and other contextual factors. The book discusses factors that can draw us into violent situations and describes how and why we make uncommon individual and collective decisions. Covering different types of surprise outcomes from protest marches and uprisings turning violent to robbers failing to rob a store at gunpoint, it shows how unfolding situations can override our motivations and strategies and how emotions and culture, as well as rational thinking, still play a part in these events. The first chapters study protest violence in Germany and the United States from 1960 until 2010, taking a detailed look at what happens between the start of a protest and the eruption of violence or its peaceful conclusion. They compare the impact of such dynamics to the role of police strategies and culture, protesters’ claims and violent motivations, the black bloc and agents provocateurs. The analysis shows how violence is triggered, what determines its intensity, and which measures can avoid its outbreak. The book explores whether we find similar situational patterns leading to surprising outcomes in other types of small- and large-scale events: uprisings turning violent, such as Ferguson in 2014 and Baltimore in 2015, and failed armed store robberies.

Goal Directed Behavior

Rapid instructed task learning (RITL) is the uniquely human ability to transform task information into goal-directed behavior without relying on trial-and-error learning. RITL is a core cognitive process supported by functional brain networks. In patients with schizophrenia, RITL ability is impaired, but the role of functional network connectivity in these RITL deficits is unknown. We investigated task-based connectivity of eight a priori network pairs in participants with schizophrenia ( n = 29) and control participants ( n = 31) during the performance of an RITL task. Multivariate pattern analysis was used to determine which network connectivity patterns predicted diagnostic group. Of all network pairs, only the connectivity between the cingulo-opercular network (CON) and salience network (SAN) during learning classified patients and control participants with significant accuracy (80%). CON-SAN connectivity during learning was significantly associated with task performance in participants with schizophrenia. These findings suggest that impaired interactions between identification of salient stimuli and maintenance of task goals contributes to RITL deficits in participants with schizophrenia.

Great Development

Over the last few years, mobile robotics has experienced a great development thanks to the wide variety of problems that can be solved with this technology. An autonomous mobile robot must be able to operate in a priori unknown environments, planning its trajectory and navigating to the required target points. With this aim, it is crucial solving the mapping and localization problems with accuracy and acceptable computational cost. The use of omnidirectional vision systems has emerged as a robust choice thanks to the big quantity of information they can extract from the environment. The images must be processed to obtain relevant information that permits solving robustly the mapping and localization problems. The classical frameworks to address this problem are based on the extraction, description and tracking of local features or landmarks. However, more recently, a new family of methods has emerged as a robust alternative in mobile robotics. It consists of describing each image as a whole, what leads to conceptually simpler algorithms. While methods based on local features have been extensively studied and compared in the literature, those based on global appearance still merit a deep study to uncover their performance. In this work, a comparative evaluation of six global-appearance description techniques in localization tasks is carried out, both in terms of accuracy and computational cost. Some sets of images captured in a real environment are used with this aim, including some typical phenomena such as changes in lighting conditions, visual aliasing, partial occlusions and noise.

Argumentation is an important aspect in the field of education because of its impact on learning processes. At the same time, argumentation is a complex activity in terms of cognitive, relational, emotional and social dynamics. In this paper, I investigate and I describe possible difficulties encountered by children during the argumentative process. The study involves 25 preschool children at a kindergarten engaged in three building tasks. The tasks were video-recorded and the argumentative discussions transcribed. For the aim of this paper, I analyze how argumentation are distributed among participants. I select interactions in which participants apparently do not argue or there are differences in the degree of argumentative participation between participants of the same group. I analyze these interactions and moments of impasse in the argumentative steps. The findings show how the simplicity of solving the task (e.g., when children do not encounter any problem in completing the activity) and the children’s self-perception of their competences in solving the task may have an impact on argumentation activities. Moreover, this perception is co-constructed by children within the interaction. The study contributes to the line of research on designing argumentation and highlights the role of the adult in managing children’s interactions.
