    Negations in syllogistic reasoning: Evidence for a heuristic–analytic conflict

    An experiment utilizing response time measures was conducted to test dominant processing strategies in syllogistic reasoning with the expanded quantifier set proposed by Roberts (2005). Through adding negations to existing quantifiers it is possible to change problem surface features without altering logical validity. Biases based on surface features such as atmosphere, matching, and the probability heuristics model (PHM; Chater & Oaksford, 1999; Wetherick & Gilhooly, 1995) would not be expected to show variance in response latencies, but participant responses should be highly sensitive to changes in the surface features of the quantifiers. In contrast, according to analytic accounts such as mental models theory and mental logic (e.g., Johnson-Laird & Byrne, 1991; Rips, 1994) participants should exhibit increased response times for negated premises, but not be overly impacted upon by the surface features of the conclusion. Data indicated that the dominant response strategy was based on a matching heuristic, but also provided evidence of a resource-demanding analytic procedure for dealing with double negatives. The authors propose that dual-process theories offer a stronger account of these data whereby participants employ competing heuristic and analytic strategies and fall back on a heuristic response when analytic processing fails

    Storytelling with objects to explore digital archives

    Finding media in archives is difficult while storytelling with photos can be fun and supports memory retrieval. Could the search for media become a natural part of the storytelling experience? This study investigates spatial interactions with objects as a means to encode information for retrieval while being embedded in the story flow. An experiment is carried out in which participants watch a short video and re-tell the story using cards each of which shows a character or object occurring in the video. Participants arrange the cards when telling the story. It is analyzed what information interactions with cards carry and how this information relates to the language of storytelling. Most participants align interactions with objects with the sentences of the story while some arrange the cards corresponding to the video scene. Spatial interactions with objects can carry information on their own or complemented by language

    Reasoning in non-probabilistic uncertainty: logic programming and neural-symbolic computing as examples

    Get PDF
    This article aims to achieve two goals: to show that probability is not the only way of dealing with uncertainty (and even more, that there are kinds of uncertainty which are for principled reasons not addressable with probabilistic means); and to provide evidence that logic-based methods can well support reasoning with uncertainty. For the latter claim, two paradigmatic examples are presented: Logic Programming with Kleene semantics for modelling reasoning from information in a discourse, to an interpretation of the state of affairs of the intended model, and a neural-symbolic implementation of Input/Output logic for dealing with uncertainty in dynamic normative context

    Co-creativity Assessment Methodology: C2Learn project deliverable no. D2.3.2

    Get PDF
    Deliverable 2.3.2 is the final installment of a document detailing the C2Learn Co-creativity Assessment Methodology, its rationale, method, tools and accompanying operationalisation. Led by the UEDIN team in close collaboration with the OU team, and other appropriate consortium members, it sets out the over-arching theoretical frame of the project further developed from Deliverable 2.2.2 which closely integrates Creative Emotional Reasoning (Deliverable 2.1.2) and Wise Humanising Creativity, and argues in turn for an integrated approach to the assessment methodology which combines documenting change and lived experience. Deliverable 2.3.2 firstly deals with theoretical and then methodological integration, and from this details the evaluation categorisation scheme. It goes on to detail the methodology, and its accompanying aims, indicators and data collection tools. The final part considers the methodology's operationalisation including the evaluation plan, inclusion of teachers, issues of analysis and synthesis, training needs and ethics

    Diversity, urban space and the right to the provincial city

    Get PDF
    Using three vignettes of the same physical space this article contributes to understanding of how the right to the city is contested in provincial England in the early twenty-first century. Oral history and ethnographic material gathered in Peterborough between 2010 and 2012 are drawn on to shed new light on the politics of diversity and urban space. This highlights the multiple place attachments and trans-spatial practices of all residents, including the white ethnic majority, as well as contrasting forms of active intervention in space with their different temporalities and affective intensities. The article carries its own diversity politics, seeking to reduce the harm done by racism through challenging the normalisation of the idea of a local, indigenous population, left out by multiculturalism. It simultaneously raises critical questions about capitalist regeneration strategies in terms of their impact both on class inequality and on the environment
