Повний текст джерелаWith the steady and rapid growth of technology, digital marketing has become one of the most common ways for advertisers to reach out to a broader audience. Instagram and Snapchat are the most commonly used social networking services among today’s adolescents that highly utilise the concept of personalised digital advertising through third parties. One-to-one marketing is a form of personalised marketing that aims to collect information about individual consumers in order to provide each individual with advertisements fitted to their interests. This study takes a closer look on how teenagers perceive the personal effect of one-to-one marketing. The empirical research was obtained from qualitative interviews carried out among teenagers aged 15 to 17 years old. Upon conclusion of the study, it was found that all respondents felt influenced by digital one-to-one marketing and are worried about the use of their information. Ultimately, respondents think the risks outweigh the benefits and want to know where the company gets their information from. In adolescents, one-to-one marketing can create needs that did not exist before and can be met through the provision of more options. Hence, one-to-one marketing has a direct impact on the purchasing behaviour of adolescents.

Creating an appropriate indoor climate is essential to worker productivity and personal happiness. It is also an area of large expenditure for building owners. And, with rising fuel costs, finding ways of reducing energy consumption is more important than ever. This idea is promoted further by the notion that most buildings are currently being run inefficiently, due to the non-adaptable nature of their control systems. Not just the occupants, but also the buildings themselves have ever changing needs, for which a single setpoint is inadequate. This dissertation presents a novel air-conditioning control system, focused around the individual, which remedies these inefficiencies through the creation of personalized environments. To date, the measurement of thermal preference has been limited to either a complex set of sensors attempting to determine a Predicted Mean Vote (PMV) value, or to direct polling of the user. The former is far too cumbersome and expensive for practical application, and the latter places an undue burden on the user. To overcome these limitations, an extremely low power, light weight, wireless sensor is developed which can measure temperature, humidity, activity and light level directly on the user's body. These data are used to immediately infer user comfort level, and to control an HVAC system in an attempt to minimize both cost and thermal discomfort. Experimental results are presented from a building under continual usage, modified with a wireless network with multiple sensing and actuating modalities.
(cont.) For four weeks, ten building occupants, in four offices and one common space, are thermally regulated via wristworn sensors controlling the local air-conditioning dampers and window operator motors. Comparisons are made to the previous four week period of standard air-conditioning control, showing an increase in comfort, while decreasing energy usage at the same time. The difficult problems of control adaptation, comfort determination, and user conflict resolution are addressed. Finally, the limitations of this format of control are discussed, along with the possible benefits and requirements of this proactive architecture.

The next era of medicine will be one of personalization, scientists and physicians promise. Personalized medicine is a refined clinical approach in which clinicians will utilize your genomic information to help you prevent disease, and tailor targeted therapies for you when you fall ill. This is the future science has slowly been approaching. However, the human genome is not enough, not unless we can decipher its language. One ambitious study to this effect is the Personal Genome Project, led by Dr. George Church at Harvard Medical School. This project will eventually recruit 100,000 volunteers to donate their genomes and a full body of information concerning their biological health. With this data, Church hopes others can cross-analyze these profiles and better determine the role in disease of each gene of the human genome. However, the Personal Genome Project is as much a study in the ethical, legal and social aspects of genomic studies as it is an effort toward personalized medicine. Church envisions a future where privacy cannot be guaranteed. Society is becoming more open and technology is more invasive than ever. Considering this, Church has informed his participants that their information will likely not remain anonymous. With their fully informed consent, he has in turn made all this data public, to promote open science. This ethical approach raises several important questions about expansive genomic studies. The scientific community will have to decide on an approach that will eventually deliver personalized medicine. On one end of the spectrum, there is Church's open approach, and the other, more security, more firewalls and more legislation. In order for personalized medicine to become a reality, society will have to prepare itself for our ever-changing ethical, technological and scientific landscape.

In Galatea, digitally augmented physical objects actively attract a person's attention to online information relevant to both the object and the person's interests. Galatea combines intelligent software agents and digitally augmented physical objects to uniquely bridge the gap between the two disciplines. In a unique twist on typical Ubiquitous Computing models that require intentional request for or asynchronous, periodic delivery of information, Galatea's smart objects proactively attract the attention of a nearby person by blinking a light when there is relevant information about the object. The object also sends the relevant information to the person's cell phone. We use books as our test case. Any augmented book can visually attract a user's attention when there is information it believes is relevant to the user. This information is personalized, i.e. unique to the person's interests, the current location, and the book, and when appropriate is delivered unobtrusively using the person's cell phone interface. A user can likewise request information from the books in the nearby vicinity by searching the books using their cell phone. A user study of and demonstration responses to Galatea show tradeoffs between the benefits of orienting information in objects and its usefulness as a collaborative tool, versus its potential as a distracting and invasive interface.

This thesis describes a new framework that enables a wider range of people to extend and customize programming environments to support more personalized explorations, especially in the physical world. While the vocabulary of the Scratch programming language (http://scratch.mit.edu) can be extended to access hardware devices and web services through Scratch Extensions, creating an extension is not trivial and requires a significant level of technical expertise. This occasionally means having less personalized, more abstract language for those extensions. I describe and analyze the design of Personalized Extensions, an extension mechanism that allows the users of Scratch to personalize abstract Scratch extensions, and consequently help other users to have more meaningful learning experiences in the worlds which Scratch extensions allow them to access. I conclude by reflecting on some case studies where personalized extensions were used, and how they affected the learning experience of the users.

Users have high-level goals when they browse the Web or perform searches. However, the two primary user interfaces positioned between users and the Web, Web browsers and search engines, have very little interest in users' goals. Present-day Web browsers provide only a thin interface between users and the Web, and present-day search engines rely solely on keyword matching. This thesis leverages large knowledge bases of semantic information to provide users with a goal-oriented Web browsing experience. By understanding the meaning of Web pages and search queries, this thesis demonstrates how Web browsers and search engines can proactively suggest content and services to users that are both contextually relevant and personalized. This thesis presents (1) Creo, a Programming by Example system that allows users to teach their computers how to automate interactions with their favorite Web sites by providing a single demonstration, (2) Miro, a Data Detector that matches the content of a Web page to high-level user goals, and allows users to perform semantic searches, and (3) Adeo, an application that streamlines browsing the Web on mobile devices, allowing users to complete actions with a minimal amount of input and output.
(cont.) An evaluation with 34 subjects found that they were more effective at completing tasks when using these applications, and that the subjects would use these applications if they had access to them. Beyond these three user interfaces, this thesis also explores a number of underlying issues, including (1) automatically providing semantics to unstructured text, (2) building robust applications on top of messy knowledge bases, (3) leveraging surrounding context to disambiguate concepts that have multiple meanings, and (4) learning new knowledge by reading the Web.

Ontologies, or ways of categorizing and describing things, have application to organizing information for human access and allowing software agents to exchange knowledge. The traditional approaches to ontology development involve dedicated effort by a small team of knowledge engineers in a slow and expensive process. We show that a composite ontology of information resources can be constructed from the personal ontologies of individuals in an organization via an ongoing process that combines normal personal organizing activities with low-impedence computer mediation. The MindShare approach is designed to facilitate this process within an organization of people who wish both to organize internal and public information for their personal benefit, and to leverage information previously discovered by others within the organization. MindShare software provides the user with an animated graphical ontology browser for organizing Web documents according to his or her personal ontology, and also for accessing the composite ontology as extensions of the personal ontology with an assisted bimodal browsing interface. The personal ontologies are mapped to the composite ontology by a process that includes MindShare term-based information retrieval methods to suggest existing topics when a user chooses to add a topic, and a variety of user interface affordances that encourage the user to add exposed pieces of the composite ontology to their personal ontology (and later build upon those pieces). We implemented the MindShare software and conducted an initial trial with a small group of users. The MindShare approach behaved as hoped, suggesting that the approach has promise and merits further investigation.

Повний текст джерелаKommunikation av data driven och individanpassad marknadsföring är idag vanligt bland stora kundbaserade företag med lojalitetsprogram. E-post har blivit standard som digital kanal för sådan typ av kommunikation främst för att den erbjuder hög kostnadseffektivitet och goda möjligheter att skapa attraktivt innehåll anpassat efter kund. Den här uppsatsen har som syfte att identifiera vilka effekter individanpassad kommunikation genom e-post kan leda till inom lojalitetsprogram, samt om företag bör investera i individanpassad e-post kommunikation. Metoden bestod av två kvantitativa fallstudier i form av analys av elva individanpassade nyhetsbrev och ett aktiveringsbrev av ett företag verksam inom bränsle och närbutik. En serie kvalitativa intervjuer hölls också med individer verksamma inom individanpassad kommunikation. Resultaten visar att lojalitetsmedlemmarna i hög grad accepterar kommunikationen och nås av innehållet. De individanpassade nyhetsbreven visade inga tydliga positiva effekter inom försäljning, butiksbesök eller merförsäljning. Aktiveringsmailet, som var en del av aktiveringsfasen i kundlivscykeln visade på mer lovande resultat genom att leda till fler butiksbesök och ledde till en positiv merförsäljning. Ytterligare effekter inom byteskostnad och varumärkesmedvetenhet identifierades även, såvida innehållet når kunderna och uppfattas som relevant. Om inte riskerar innehållet att stöta bort kunderna eftersom det idag förväntas att digital marknadsföring är individanpassad. Sammanfattningsvis så rättfärdigar de identifierade effekterna investering i individanpassad kommunikation, men man bör vara medveten om vilka effekterna är.

Повний текст джерелаRecently, search engines have become the main source of information for many users and have been widely used in different fields. However, Information Retrieval Systems (IRS) face new challenges due to the growth and diversity of available data. An IRS analyses the query submitted by the user and explores collections of data with unstructured or semi-structured nature (e.g. text, image, video, Web page etc.) in order to deliver items that best match his/her intent and interests. In order to achieve this goal, we have moved from considering the query-document matching to consider the user context. In fact, the user profile has been considered, in the literature, as the most important contextual element which can improve the accuracy of the search. It is integrated in the process of information retrieval in order to improve the user experience while searching for specific information. As time factor has gained increasing importance in recent years, the temporal dynamics are introduced to study the user profile evolution that consists mainly in capturing the changes of the user behavior, interests and preferences, and updating the profile accordingly. Prior work used to discern short-term and long-term profiles. The first profile type is limited to interests related to the user's current activities while the second one represents user's persisting interests extracted from his prior activities excluding the current ones. However, for users who are not very active, the short-term profile can eliminate relevant results which are more related to their personal interests. This is because their activities are few and separated over time. For users who are very active, the aggregation of recent activities without ignoring the old interests would be very interesting because this kind of profile is usually changing over time. Unlike those approaches, we propose, in this thesis, a generic time-sensitive user profile that is implicitly constructed as a vector of weighted terms in order to find a trade-off by unifying both current and recurrent interests. User profile information can be extracted from multiple sources. Among the most promising ones, we propose to use, on the one hand, searching history. Data from searching history can be extracted implicitly without any effort from the user and includes issued queries, their corresponding results, reformulated queries and click-through data that has relevance feedback potential. On the other hand, the popularity of Social Media makes it as an invaluable source of data used by users to express, share and mark as favorite the content that interests them

As access to education technology - high-speed Internet connectivity, lower-cost computers, and online learning programs - has increased over the past five years in K-12 schools in the United States, the debate over technology's place in the classroom, specifically its ability to usher in a new era of education personalized to meet the needs of every individual student, has raged on. Much of the narrative perpetuated by technology companies around educational reform has centered on an idea that outside, tech-driven "disruption" is needed in order for real transformation. However, many school districts have found more success moving towards personalized learning when the disruption is homegrown, scaled carefully, involves all community stakeholders, and is driven by pedagogy, not technology. This thesis examines in depth one school district, Kettle Moraine School District in Wisconsin, and their success in creating personalized learning experiences for their students, as a case study for how other districts might approach homegrown disruptions of their own.

Storytelling is a fundamental way in which human beings make sense of the world. Animated movies tell stories that engage audience across culture and age groups. I designed and built My Personalized Movies (MPM), a novel system where animated stories are automatically created based on data provided by individuals. The data include self-tracked mood and behavior captured in quantitative measures and descriptive text. MPM is designed to engage viewers through an emotive narrative, induce self-reflection about their mood and behavior patterns, and to improve self-compassion and self-esteem, which mediates behavior change. I demonstrate with a few stages of studies, involving in total 107 participants, that viewers show strong emotional engagement with MPM and can explicitly connect animated characters' stories to one's past experiences. An analysis of 22 participants' facial expression data during MPM reveals that participants' change in implicit self-esteem is positively correlated with the happiness of their facial expression. Participants with higher depression severity, as measured by PHQ9, showed less positive facial expression at the happy moments in the animation.

The Escurra y Salas (2014) Social Media Addiction Questionnaire and the Personality Inventory “Big Five Inventory-15-P (Dominguez-Lara & Merino-Soto, 2018) were administered. The results reveal that there is a great relationship between SNA and Responsibility, while Neuroticism, Affability and Extraversion correlations are moderate; the lowest relationship is presented by Openess to Experience. Likewise, the comparisons according to sex indicate that the scores in the personality factors are higher in women; while, males have higher scores on the ARS dimensions. However, the magnitude of the difference is small for most. The results and their implications are discussed.

Повний текст джерела[CA] En els últims anys, els models d'aprenentatge automàtic profund (AP) han revolucionat els sistemes de processament de llenguatge natural (PLN). Hem estat testimonis d'un avanç formidable en les capacitats d'aquests sistemes i actualment podem trobar sistemes que integren models PLN de manera ubiqua. Alguns exemples d'aquests models amb els quals interaccionem diàriament inclouen models que determinen la intenció de la persona que va escriure un text, el sentiment que pretén comunicar un tweet o la nostra ideologia política a partir del que compartim en xarxes socials. En aquesta tesi s'han proposats diferents models de PNL que aborden tasques que estudien el text que es comparteix en xarxes socials. En concret, aquest treball se centra en dues tasques fonamentalment: l'anàlisi de sentiments i el reconeixement de la personalitat de la persona autora d'un text. La tasca d'analitzar el sentiment expressat en un text és un dels problemes principals en el PNL i consisteix a determinar la polaritat que un text pretén comunicar. Es tracta per tant d'una tasca estudiada en profunditat de la qual disposem d'una vasta quantitat de recursos i models. Per contra, el problema del reconeixement de la personalitat és una tasca revolucionària que té com a objectiu determinar la personalitat dels usuaris considerant el seu estil d'escriptura. L'estudi d'aquesta tasca és més marginal i en conseqüència disposem de menys recursos per abordar-la però no obstant i això presenta un gran potencial. Tot i que el fouc principal d'aquest treball va ser el desenvolupament de models d'aprenentatge profund, també hem proposat models basats en recursos lingüístics i models clàssics de l'aprenentatge automàtic. Aquests últims models ens han permès explorar les subtileses de diferents elements lingüístics com ara l'impacte que tenen les emocions en la classificació correcta del sentiment expressat en un text. Posteriorment, després d'aquests treballs inicials es van desenvolupar models AP, en particular, Xarxes neuronals convolucionals (XNC) que van ser aplicades a les tasques prèviament esmentades. En el cas de el reconeixement de la personalitat, s'han comparat models clàssics de l'aprenentatge automàtic amb models d'aprenentatge profund la qual cosa a permet establir una comparativa de les dos aproximacions sota les mateixes premisses. Cal remarcar que el PNL ha evolucionat dràsticament en els últims anys gràcies a el desenvolupament de campanyes d'avaluació pública on múltiples equips d'investigació comparen les capacitats dels models que proposen sota les mateixes condicions. La majoria dels models presentats en aquesta tesi van ser o bé avaluats mitjançant campanyes d'avaluació públiques, o bé s'ha emprat la configuració d'una campanya pública prèviament celebrada. Sent conscients, per tant, de la importància d'aquestes campanyes per a l'avanç del PNL, vam desenvolupar una campanya d'avaluació pública on l'objectiu era classificar el tema tractat en un tweet, per a la qual cosa vam recollir i etiquetar un nou conjunt de dades. A mesura que avançàvem en el desenvolupament del treball d'aquesta tesi, vam decidir estudiar en profunditat com les XNC s'apliquen a les tasques de PNL. En aquest sentit, es van explorar dues línies de treball.En primer lloc, vam proposar un mètode d'emplenament semàntic per RNC, que planteja una nova manera de representar el text per resoldre tasques de PNL. I en segon lloc, es va introduir un marc teòric per abordar una de les crítiques més freqüents de l'aprenentatge profund, el qual és la falta de interpretabilitat. Aquest marc cerca visualitzar quins patrons lèxics, si n'hi han, han estat apresos per la xarxa per classificar un text.
[EN] In the last years, Deep Learning (DL) has revolutionised the potential of automatic systems that handle Natural Language Processing (NLP) tasks. We have witnessed a tremendous advance in the performance of these systems. Nowadays, we found embedded systems ubiquitously, determining the intent of the text we write, the sentiment of our tweets or our political views, for citing some examples. In this thesis, we proposed several NLP models for addressing tasks that deal with social media text. Concretely, this work is focused mainly on Sentiment Analysis and Personality Recognition tasks. Sentiment Analysis is one of the leading problems in NLP, consists of determining the polarity of a text, and it is a well-known task where the number of resources and models proposed is vast. In contrast, Personality Recognition is a breakthrough task that aims to determine the users' personality using their writing style, but it is more a niche task with fewer resources designed ad-hoc but with great potential. Despite the fact that the principal focus of this work was on the development of Deep Learning models, we have also proposed models based on linguistic resources and classical Machine Learning models. Moreover, in this more straightforward setup, we have explored the nuances of different language devices, such as the impact of emotions in the correct classification of the sentiment expressed in a text. Afterwards, DL models were developed, particularly Convolutional Neural Networks (CNNs), to address previously described tasks. In the case of Personality Recognition, we explored the two approaches, which allowed us to compare the models under the same circumstances. Noteworthy, NLP has evolved dramatically in the last years through the development of public evaluation campaigns, where multiple research teams compare the performance of their approaches under the same conditions. Most of the models here presented were either assessed in an evaluation task or either used their setup. Recognising the importance of this effort, we curated and developed an evaluation campaign for classifying political tweets. In addition, as we advanced in the development of this work, we decided to study in-depth CNNs applied to NLP tasks. Two lines of work were explored in this regard. Firstly, we proposed a semantic-based padding method for CNNs, which addresses how to represent text more appropriately for solving NLP tasks. Secondly, a theoretical framework was introduced for tackling one of the most frequent critics of Deep Learning: interpretability. This framework seeks to visualise what lexical patterns, if any, the CNN is learning in order to classify a sentence. In summary, the main achievements presented in this thesis are: - The organisation of an evaluation campaign for Topic Classification from texts gathered from social media. - The proposal of several Machine Learning models tackling the Sentiment Analysis task from social media. Besides, a study of the impact of linguistic devices such as figurative language in the task is presented. - The development of a model for inferring the personality of a developer provided the source code that they have written. - The study of Personality Recognition tasks from social media following two different approaches, models based on machine learning algorithms and handcrafted features, and models based on CNNs were proposed and compared both approaches. - The introduction of new semantic-based paddings for optimising how the text was represented in CNNs. - The definition of a theoretical framework to provide interpretable information to what CNNs were learning internally.

Повний текст джерелаThe purpose of this essay has been to describe and compare the personal qualities that the Swedish newspaper Dagens Nyheter (DN) tried to associate Barack Obama and John McCain with during the American presidential election campaign 2008. The main question to be answered is: What social and physical characters as well as what personal experiences, interest and resources did DN tried to emphasize regarding John McCain and Barack Obama during the American presidential election campaign 2008. The theoretical starting-point has been John B Thompson’s theory of the mediated publicity and John Corner´s theory of political persona and spheres of action. Various DN news texts, in all 38 articles, have been examined by content analysis from 25th of august to the 4th of November. The main results show that the most frequent mentioned qualities about Barack Obamas was his skin colour, ethnicity and speech talents. The most frequent mentioned qualities about John McCain was his age and his military experiences from the Vietnam War. The conclusion that can be drawn from this study is that the qualities described in DN created a picture of two different politicians. Many of the qualities that was mentioned have no connection to politics and even if they was just mentioned one time can they play a significant role in trying to build confidence. Many of the qualities that was mentioned are qualities that necessary not have to be seen as positive.

Повний текст джерелаThe following study has aimed to investigate how Instagram's primary user group in Sweden experiences targeted marketing from companies that actively place themselves on Instagram. The study has had a qualitative design and the methods used for the collection of data have been seven individual in-depth interviews with girls aged 20-25, which is a part of Sweden's primary user group today. The in-depth interviews have also been supplemented with observations where the interviewees were asked to use Instagram to show their daily activity in the application and exposure to personalized advertising. The result that emerged from the collected empirical data and the theory in the study showed that the experience of the individualized marketing from companies and Influences on Instagram was mixed negatively and positively. Those who favored the marketing considered to a greater extent that the advertising they took part of was relevant and adapted to them. Instead, the negative participants of the interview meant that the advertisement lacked a personal connection to them and therefore felt irrelevant. In the study, on the other hand, it emerged that the participants experienced the individualized advertising from companies best in the form of collaborations with Influences and the advertising that companies shared in their own company accounts that the interviewee himself chose to follow. The form that they experienced was least personalized for them was the advertising that came from companies through direct mail in the participants' Instagram feed.

Повний текст джерелаThe present research work, consists of determining the personality in the management of middle management executives in the business sector, based on risk analysis in decision making. Mid-level executives were analyzed, as they have autonomy to make decisions that directly impact the destiny of the organization. The research problem was to analyze the direct relationship between personality traits and risk in decision making (assumption or aversion to risk), aimed at the management and business performance of a middle management executive. This analysis will help organizations to implement personality traits within the work profile in the personnel selection process. Four criteria were analyzed: (i) There is a direct relationship between personality traits and risk in decision-making, (ii) The personality traits of middle management executives oriented to their management and performance in the business sector, (iii) There are different researches such as the Myers-Briggs type indicator that allows us to identify the most important personality traits and finally (iv) Demonstrate the relevance of the personality traits that middle management executives have in their business management. Our research aims to recommend the implementation of a profile (personality traits) best suited to the personality traits of middle management executives that ensure a good working environment within the organization.

Повний текст джерелаHuman dynamics is an essential aspect of human centric computing. As a transdisciplinary research field, it focuses on understanding the underlying patterns, relationships, and changes of human behavior. By exploring human dynamics, we can understand not only individual’s behavior, such as a presence at a specific place, but also collective behaviors, such as social movement. Understanding human dynamics can thus enable various applications, such as personalized location based services. However, before the availability of ubiquitous smart devices (e.g., smartphones), it is practically hard to collect large-scale human behavior data. With the ubiquity of GPS-equipped smart phones, location based social media has gained increasing popularity in recent years, making large-scale user activity data become attainable. Via location based social media, users can share their activities as real-time presences at Points of Interests (POIs), such as a restaurant or a bar, within their social circles. Such data brings an unprecedented opportunity to study human dynamics. In this dissertation, based on large-scale location centric social media data, we study human dynamics from both individual and collective perspectives. From individual perspective, we study user preference on POIs with different granularities and its applications in personalized location based services, as well as the spatial-temporal regularity of user activities. From collective perspective, we explore the global scale collective activity patterns with both country and city granularities, and also identify their correlations with diverse human cultures

Повний текст джерелаThe humanization process has probably involved a series of brain morphological changes. The anatomical degree of development of functionally relevant brain regions, characterized by its great variation and the existence of a marked hemispheric asymmetry could be related to individual differences in cognitive styles and personality traits. There are numerous studies that expose different inter-hemispheric morphological asymmetries. The most replicated findings are asymmetries in lateral areas of the cerebral hemispheres and the anterior cingulate region. However, fewer studies have focused on studying the relevance and functional significance of these asymmetries and the individual variation, although they have provided data that have partially explained the relationship between volume and brain structures and higher functions. This paper aims to investigate the functional significance of the anatomical variability of two brain regions that are characteristically asymmetric and which have special relevance in modulating the behaviour of human beings. First of all, the volume of the perisylvian region has been measured as the paradigmatically region that supports language functions; secondly the medial surface of the cingulate cortex was measured to investigate its correlation with behavioural styles. Four studies were developed under these two lines of research. In the first study, the aim was to find the best anatomical correlation related to the known percentage of cerebral dominance for language. In recent years, white matter is leading a greater role. We observed that the total volume measured by magnetic resonance imaging (MRI) in 3D of the perisylvian region would not differ in both hemispheres. Instead, the regional representative volume of each lobe was different in the two hemispheres. Specifically, the relative volume of white matter had the highest percentages in the frontal regions, temporal and parietal lobes. In the right hemisphere, the highest percentage of white matter was located in the temporo-parieto-occipital region. Consequently, the parameter that best explains the anatomical lateralization of language is the asymmetry of the relative volume of white matter located in the frontal and temporal perisylvian regions. In the same line of study and applied to children with specific language impairment (SLI) and using measurements by voxels based morphometry (VBM), we sought to find a characteristic pattern of this entity. It has been observed that children with SLI show an overall increase in white matter and grey matter volumes and a different relative distribution compared to the control group. Compensation mechanisms and temporary dynamic modulation to which the brain is exposed may explain these abnormalities at structural level. The second line of research intended to analyze the variability of the surface of the anterior cingulate gyrus in healthy volunteers participating. In the first study it was found that a larger size of the right anterior cingulate cortex in both sexes was related to a temperamental disposition towards fear and anticipatory suffering. Additionally, a higher prevalence of these traits in women may be associated with an increased size of this region. The role of women throughout history can explain these anatomical differences between genders. Finally, the last study we focused on the relationship between alexithymia and the surface of the right anterior cingulate cortex. We observed that high levels of alexithymia correlated with an increased area of the right anterior cingulate cortex and interpreted as a good adaptation of humans in potential problematic situations.
