Talent development is an approach to education for advanced achievement. Traditionally, many models of advanced education focus on the identification of young people who are already performing at high levels, interpreting that performance as evidence that the student needs additional advanced services. In contrast, talent development focuses on providing opportunity to young people who may have the potential to perform at those advanced levels. This talent development approach, with its focus on potential rather than performance, tends to incorporate inclusive, developmental, and sociocultural perspectives that emphasize striving toward the possible over living with current realities. The theory of mind (ToM) refers to how people understand their own thoughts and feelings and those of other beings. It is a crucial cognitive mechanism for social interactions and communication. It helps us to predict, to explain, and to manipulate behaviors or mental states. Moreover, this skill is shared by almost all human beings beyond early childhood. The literature presents different explicit false-belief tasks as a means of investigating ToM in children (e.g., one of the most famous is known as the Sally-Anne task). Although children younger than 4 years usually fail in these explicit tasks, it cannot be excluded that some less complex forms of understanding mental states develop earlier. So, in order to investigate the precursors that anticipate the emergence of a more mature representational system, many recent studies on infants’ beliefs have demonstrated, in the last decade, a very early sensitivity specifically to the false beliefs of others by using implicit looking-time tasks. This entry starts with the definition of the theory of mind and its history, before moving on to summarize developmental research in this area. Finally, it focuses on the relation between theory of mind and the possible with some reflections on how an increasing consciousness of the variety of situations that the possible presents to us could allow people to choose the best alternative for themselves and others. The present chapter aims to describe tolerance of ambiguity (TA) to make it more tangible, to disambiguate without reducing, and indeed expand the concept. The concept depends on and is shaped by perspectives related to cultural contexts, points to how humans relate to an immediate or distant future, and has emergent properties. TA seems to share meanings and properties with the concept of “Possibilities.” TA might in fact encompass both “Possibilities” as well as “Uncertainties,” representing two sides of the same coin. Broadly, all these concepts are found in the spaces between nature and humans’ relation with them. Above all, the TA concept is amorphous, abstract, and covers relationships with other concepts in a wide array of domains. Aspects are discussed in relation with existent literature, time issues, levels and lenses of research, and an application in the domain of creativity. Throughout the chapter, possibilities are suggested for further directions of research. Central to understanding and measuring TA is its cultural embeddedness, also of the researcher her/himself. Transdisciplinarity is a practice that transcends disciplines and fields, extending the notion of what is known and knowable and what is possible to discover and create across, between, and beyond all our disciplines. As such, it is a practice that takes place in the emergent spaces between disciplines, which some writers believe is the future of discovery (Johansson F, The Medici effect. Harvard Business School Press, 2004). It is being hailed as a new way to tackle our most complex, networked challenges, yet it is also one of the most ancient ways of seeing the world as a connected whole, as evidenced by Indigenous cultures that do not separate their ethics from their geography, or their religion from their science (Yunkaporta T, Sand talk, how indigenous thinking can save the world. Text, Melbourne, 2019). It excludes no discipline, field, stakeholder, or country and is therefore described as an attempt at a unified field of knowledge – an inherently spiritual notion for some (Nuñez MC, Transdisciplinary Journal of Engineering & Science 2, 2011): “The keystone of transdisciplinarity is the semantic and practical unification of the meanings that traverse and lie beyond different disciplines” (Nicolescu B, Manifesto of Transdisciplinarity. Suny Press, 2002). This entry presents the construct of transformational creativity – creativity that makes a positive, meaningful, and potentially enduring difference to the world. People who are transformationally creative seek to make the world a better place. I first discuss creativity and then positive creativity, reviewing their strengths and drawbacks. Then I discuss three types of transformational creativity – fully transformational creativity, self-transformational creativity, and other-transformational creativity. I further discuss pseudotransformational creativity – creativity that is presented with the pretense of making the world a better place but that really is intended only to enhance the prospects of the creators. There are three types of pseudotransformational creativity – fully pseudotransformational creativity, self-destructive pseudotransformational creativity, and other-destructive pseudotransformational creativity. It has been a mistake, I believe, merely to teach for creativity, because so much of creativity has been put to bad uses. We should instead focus on teaching for the transformational creativity that makes the world better, not worse. Personal change is generally considered as a gradual and linear process, which occurs either as a result of maturation over the lifespan or as the result of a therapeutic interventions. However, research from different disciplines – including anthropology, philosophy and psychology – suggests the existence of a second type of change – transformative or transformational – which involves a radical and long-lasting shift in the individual’s core beliefs, values, and attitudes. In this contribution, I will review key definitions and conceptualizations of transformative experience, discuss the scientific and practical relevance of this construct, and suggest some future directions for research.
