REMIT – Research on Economics, Management and Information Technologies
Centro de investigação que que tem como objetivo principal produzir e disseminar conhecimento teórico e aplicado que possibilite uma maior compreensão das dinâmicas e tendências económicas, empresariais, territoriais e tecnológicas do mundo contemporâneo e dos seus efeitos socioeconómicos. O REMIT adota uma perspetiva multidisciplinar que integra vários domínios científicos: Economia e Gestão; Ciências e Tecnologia; Turismo, Património e Cultura. Founded in 2017, REMIT – Research on Economics, Management and Information Technologies is a research unit of Portucalense University. Based on a multidisciplinary and interdisciplinary perspective it aims at responding to social challenges through a holistic approach involving a wide range of scientific fields such as Economics, Management, Science, Technology, Tourism, Heritage and Culture. Grounded on the production of advanced scientific knowledge, REMIT has a special focus on its application to the resolution of real issues and challenges, having as strategic orientations: - the understanding of local, national and international environment; - the development of activities oriented to professional practice, namely in the business world.

    The Intolerance of Uncertainty Scale (IUS): Translation and adaptation to European Portuguese
    2022-10 - Botelho, Catarina; Barbosa, Fernando; Campos, Carlos; Fernandes, Carina; Ferreira-Santos, Fernando; Marques-Teixeira, João; Pasion, Rita; Seixas, Carlos; Paiva, Tiago O.; Seixas, Carlos
    Intolerance of uncertainty is defined as the individual’s excessive propensity to find unacceptable the probability of a negative event occurring (Dugas et al., 2001b; Buhr & Dugas, 2002). This propensity is brought up bya set of negative beliefs about uncertainty and its consequences (e.g., uncertainty is unacceptable and should be avoided, and/or it leads to the inability to act;Buhr & Dugas, 2002; Freeston et al., 1994; Sexton & Dugas, 2009).

    Uncertainty deconstructed: conceptual analysis and state-of-the-art review of the ERP correlates of risk and ambiguity in decision-making

    Risk and uncertainty are central concepts of decision neuroscience. However, a comprehensive review of the literature shows that most studies define risk and uncertainty in an unclear fashion or use both terms interchangeably, which hinders the integration of the existing findings. We suggest uncertainty as an umbrella term that comprises scenarios characterized by outcome variance where relevant information about the type and likelihood of outcomes may be somewhat unavailable (ambiguity) and scenarios where the likelihood of outcomes is known (risk). These conceptual issues are problematic for studies on the temporal neurodynamics of decision-making under risk and ambiguity, because they lead to heterogeneity in task design and the interpretation of the results. To assess this problem, we conducted a state-of-the-art review of ERP studies on risk and ambiguity in decision-making. By employing the above definitions to 16 reviewed studies, our results suggest that: (a) research has focused more on risk than ambiguity processing; (b) studies assessing decision-making under risk often implemented descriptive-based paradigms, whereas studies assessing ambiguity processing equally implemented descriptive- and experience-based tasks; (c) descriptive-based studies link risk processing to increased frontal negativities (e.g., N2, N400) and both risk and ambiguity to reduced parietal positivities (e.g., P2, P3); (d) experience-based studies link risk to increased P3 amplitudes and ambiguity to increased frontal negativities and the LPC component; (e) both risk and ambiguity processing seem to be related with cognitive control, conflict monitoring, and increased cognitive demand; (f) further research and improved tasks are needed to dissociate risk and ambiguity processing.

    A Domain-specific Risk-attitude Scale (DRaS): Translation and adaptation to European Portuguese
    2022-10 - Botelho, Catarina; Barbosa, Fernando; Campos, Carlos; Fernandes, Carina; Ferreira-Santos, Fernando; Marques-Teixeira, João; Pasion, Rita; Seixas, Carlos; Seixas, Carlos
    Risk attitude, as conceptualized in the classic economic approach, reflects the individual’s sensitivity to disparities in outcomes (i.e., payoffs) variance (Yechiam & Ert, 2011). Brachinger and Weber (1997) further propose that risk attitude depends on the tendency to prefer/avoid risk over certainty. Thus, the degree of risk acceptance underlies risk attitudes. Likewise, Risk-Return models (Weber & Milliman, 1997; Weber, 2010) theorize that risk attitude reflects the preference for risky options. This risk preference, in turn, depends on the trade-off between an option’s expected benefit (subjective expected value) and its riskiness (an idiosyncratic variable that depends on the context and content of the decision).
