Chatbots are software applications assimilating human communication with the aim to raise adherence and engagement between human-systems interaction. Text messaging-based conversational agents (CAs) make an interesting use of natural language processing and improve by learning, allowing coherent two-way communication with humans, either oral or written as well as real-time decision-making. Chatbots serve as means of learning and teaching, as virtual assistants and social companions. Machine learning algorithms embedded into Chatbots simulate human cognition, including cognitive learning, decision making and adaptation to the environment. Thus, the future of artificial intelligence in Chatbots lies in the development of a global, reliable and sustainable ecosystem of knowledge, skills and values by bringing together all interested stakeholders, such as scientists, consumers, businesses and the state. Such effective customized/personalized learning frameworks depend on sophisticated c...

Gender equality and digital development are inextricably linked. On the other hand digital skills are in increased demand due to the digital skill gap expanding. Most of the tech nation’s reports have shown that men still outweigh women by 3 to 1. This study aims to expound the relationship between digital technology and women’s leadership in business and society and try to clarify the reasons that women fall short of the demands of the digital sector as it is increasingly growing.

The human brain’s structure operates as a systemic whole with an absolute interdependence between its respective parts. Processes, such as information, consciousness, awareness, conscience depict humans’ layered consciousness state, but also the wholeness, coherence and continuity of human cognition. Awareness contains self-awareness, a fundamental metacognitive ability, through which individuals perceive the internal world of thoughts, reflect, imagine, feel emotions and daydream as well as external awareness, through which individuals perceive the outside world with the help of the five senses. Moreover, neuroplasticity and consciousness are bi-directionally connected; consciousness, on the one hand, is the result of the growing complexity of the brain connectivity and, on the other hand, neuroplasticity stems from reorganizing brain connections through learning activities. The conscious brain is in a perpetual state of learning and evolvement; it learns how to describe and re-des...

Motivation, affect and cognition are interrelated. However, the control of attentional deployment and more specifically, attempting to provide a more complete account of the interactions between the dorsal and ventral processing streams is still a challenge. The interaction between overt and covert attention is particularly important for models concerned with visual search. Further modeling of such interactions can assist to scrutinize many mechanisms, such as saccadic suppression, dynamic remapping of the saliency map and inhibition of return, covert pre-selection of targets for overt saccades and online understanding of complex visual scenes.

There is a bidirectional relation between one’s executive functioning abilities and problem solving skills as they are both based on self-control. “Hot” and “cold” executive functions account for individuals’ cognitive control and emotional regulation. In addition, problem solving is tied to metacognitive awareness processes, necessary for applying executive function skills in goal setting and decision making situations. Therefore, individuals’ overall cognitive flexibility and emotional regulation can promote the quality, quantity and speed of decision-making processes, such as adaptable and creative information processing as well as efficiency in setting and prioritizing goals. Moreover, individuals with ADHD, Autism Spectrum Disorder, Oppositional Defiant Disorder and individuals with other comorbid states, such as older adults, individuals with Traumatic Brain Injury (TBI) can counterbalance their cognitive control deficits through enhancing their problem solving skills. In addi...

Current article aims to shed light on the reciprocal relation between attentional control and emotional regulation. More specifically, there is a verified relation between attention and cognitive, metacognitive and emotional processes, such as memory, perception, reasoning as well as inhibitory control, cognitive flexibility, self-monitoring and positive moods. In addition, positive mood has been already reciprocally related to a broad attentional scope as well as to an increased cognitive flexibility. Future research should focus on the effects of attentional control on cognitive control processes, thereby, on individuals’ emotional regulation, as a whole. Evidently, an advanced research in the relation of attentional control and emotional regulation could develop a comprehensive methodology for counterbalancing the difficulties facing individuals with ADHD, Autism Spectrum Disorder, Oppositional Defiant Disorder or even depression.

The present questionnaire-based study examines the views of 428 Greek students (aged 13–18 years) from 30 secondary education schools in Athens, who have experienced cooperative learning in group work – an instructional learning strategy not often implemented in Greek schools. The research focuses on students’ preferences as regards the composition of their group and the distribution of roles and tasks within it, and finally the evaluation of and the reward for personal and group performance. Data elaboration, statistical and factor analysis showed that students participate more willingly in group work when wider autonomy is provided and their friends participate in the group, although new friendly relationships with the other members are not developed. It also showed that Greek students prefer clearly defined tasks, seek mainly cognitive attainments, want to be assessed on the basis of socio-affective skills development, dislike grade rewards for group work attainments and prefer n...

Cognitive training and assessment refers to ICTs and their relation with students, students with learning disabilities and adults with dementia. This article revises on contemporary research concerning ICTs effectiveness on the training and assessment of attention, memory and executive control functions. Artificial intelligence seems to hold a significant role in the field of cognitive training and rehabilitation as its adaptability and interactivity, enhance users’ motivation and involvement. Moreover, artificial intelligence in combination with other applications provides the means for holistic and cost-effective cognitive interventions through its integrative information processes. Evidently, educators and therapists should advocate of improvements in the engineering features of the applications as well as they should, themselves, expand the implementation of the aforementioned technological innovations in favour of the users’ cognition.

Latest trends in learning technologies verify of the fact that they are indispensable for students’ cognitive improvement. ICTs in coordination with a concrete pedagogical framework may provide students and teachers flexible, engaging, cost-effective and above all, personalized learning experiences, which focus on the adoption of the 21 century cognitive skills into the actual learning process. Such higher order thinking skills (HOTS) entail critical thinking, problem solving, independent inquiry, creativity, communication, collaboration, digital literacy. Therefore, technologically-supported educational environments aim at self-regulated and inquisitive, constructivist, knowledge building rather than knowledge accumulation.

Three key attentional mechanisms, attentional orienting (curiosity, openness and acceptance), engaging attention and sustainingmonitoring attention are the core skills on-target in any mindfulness-based program. Mindfulness skills are inherently related to top-down processes, such as awareness and reflection as well as bottom-up processes, such as emotional reappraisal, thus they can improve one’s cognitive and emotional regulation. Practitioners become more responsive, calm, and focused while experiencing less stress and distractions. Furthermore, mindfulness has been proven to foster stress resilience and create a great sense of interconnectedness so that it diminishes one’s possible involvement in impulsive behaviors. In addition, these techniques have multiple applications in modern medicine, working environments and school psychology, supported by ICTs to enhance practioners’ health status.

Problem-solving skills assessment starts with the imperative that the hypothesized construct of skills, is theoretically sound. Secondly, assessment refers to identifying and recording inductive and deductive types of reasoning as well as divergent and convergent thinking skills. The aforementioned procedures should be measured, independent of specific learning domains or knowledge backgrounds. Future research should be oriented towards the development of a prototype set of tasks that would embed problem-solving skills in different content and context areas and that would act as a model for implementation in online large-scale assessments. Furthermore, the classroom provides an environment amenable to collaborative problem solving, in which capturing the progress of students’ both social and cognitive processes through identifying the exchange of implicit and explicit types of information, remains to be sufficiently addressed. Effective collaborative problem-solving assessment is re...

Problem-solving requires creative skills, critical thinking as well the ability to implement ideas and theories in practical ways. Moreover, interactive and self-managed problem-solving experiences promote students’ motivation as expressed through the developmental progression of learners’ metacognitive skills, such as self-monitoring and self-reinforcement. Effective learning based on constructivist didactics, encompassing self-organized learning in combination with active and creative problem-solving in collaborative settings, advances students’ concomitant cognitive and meta-cognitive processes. Hence, students’ co-construction of knowledge embodied in social dynamic learning environments, such as school-based tasks leverage the semantic relationships rising from exercising, verifying and testing of knowledge through information sharing and discussion. Future studies should focus on designing interactive, adaptable, ill-defined, real-world learning environments to elicit students...

Motivation, affect and cognition are interrelated. However, the control of attentional deployment and more specifically, attempting to provide a more complete account of the interactions between the dorsal and ventral processing streams is still a challenge. The interaction between overt and covert attention is particularly important for models concerned with visual search. Further modeling of such interactions can assist to scrutinize many mechanisms, such as saccadic suppression, dynamic remapping of the saliency map and inhibition of return, covert pre-selection of targets for overt saccades and online understanding of complex visual scenes. 1 Introduction The interplay between bottom-up and top-down influences on overt attention is the key for investigating and modeling attention. More specifically, future research should begin with widening the currently narrow scope on top-down factors. Atten-tional and emotional processes are in the focus of research, although overall research in this field is just at the beginning and suffers from the diversity of concepts of both attention and emotion. Until now, models of saliency maps and research on elementary image features have not considered emotional components. Thus, it is a challenging task for future research to incorporate bottom-up factors and emotion as a strong top-down factor. 2 Theories of Attention Chun et al. [5] distinguished attention according to the types of information that attention operates over. Therefore, external attention refers to the selection and modulation of sensory information (perceptual attention), whereas internal attention includes cognitive control as well as the contents of working memory, long-term memory, task sets or response selection (central/reflective attention). Cognitive control mechanisms prioritize, independent of sensory modality, which perceptual information to select, encode and maintain in working memory, while suppressing distraction. Moreover, executive processes and working memory influence perceptual processes and guide

Three key attentional mechanisms, attentional orienting (curiosity, openness and acceptance), engaging attention and sustaining-monitoring attention are the core skills on-target in any mindfulness-based program. Mindfulness skills are inherently related to top-down processes, such as awareness and reflection as well as bottom-up processes, such as emotional reappraisal, thus they can improve one's cognitive and emotional regulation. Practitioners become more responsive, calm, and focused while experiencing less stress and distractions. Furthermore, mindfulness has been proven to foster stress resilience and create a great sense of interconnectedness so that it diminishes one's possible involvement in impulsive behaviors. In addition, these techniques have multiple applications in modern medicine, working environments and school psychology, supported by ICTs to enhance practioners' health status. Research has be focused on practioners' mindfulness skills training and assessment through smartphones as a cost-effective and usable, every day treatment.

Problem solving is the skill that coordinates all the cognitive, metacognitive and behavioral processes taking place when individuals encounter a previously unprecedented situation or difficulty. Metacognitive processes seem to play the most important role for resolving a problematic situation as individuals reflect on their acquired knowledge, skills and experiences, thus become aware of their capabilities and how to regulate them. Therefore, metacognitive awareness is the competence that mostly assists individuals in their attempt to construct new knowledge and reach their goals. Furthermore, individuals' self-assessment and peer-assessment processes could reveal their level of metacogni-tive awareness and therefore, by far, their problem solving competency. Consequently, ICTs could capture individuals' problem solving skills through tracking down and analyzing the latters' cognitive and metacognitive processes as well as their behavioral patterns. The aforementioned computer-based assessment could consist of a fuzzy expert system with domain knowledge from an automated task-based test with particular solution strategies in combination with log data for identifying and classifying one's level of problem solving ability according to specific criteria.
