Groups are not always the same
1993
The idea of supporting group meetings at the same time and at the same place by computer raises the problem of how salient features of group behaviors are understood in meetings. In this paper we take a critical look at several beliefs about group behaviors in research dealing with electronic meeting systems (EMS). The paper argues based on an empirical study that the concept of a small, cohesive business team, so widely held, in all EMS research is not necessarily a valid starting point in thinking of meeting support. In particular, the paper critically evaluates a number of beliefs of user aspects, group features such as composition, structure and protocols, and task characteristics such …
Can Artificial Intelligence Interprete Legal Norms? A Problem of Practical Reason
2021
La formalización del razonamiento jurídico y, específicamente, de la interpretación es un viejo sueño de nuestra cultura. Hoy, la Inteligencia Artificial parece lista para cumplir esa tarea. Teóricos computacionales y lógicos están desarrollando herramientas técnicas para estructurar modelos formales de interpretación jurídica útiles para la Inteligencia Artificial. Sin embargo, estos esfuerzos han conseguido sólo formalizaciones abstractas, que no son capaces de resolver cuestiones materiales sobre la respuesta correcta ante un caso nuevo. Los algoritmos no pueden descubrir, ni evaluar, problemas humanos sin la ayuda de programadores; no pueden decidir entre hipótesis interpretativas alter…
Explorations of familiarity produced by words with specific combinations of letters
2010
We explore familiarity-based recognition using a paradigm devised by Parkin et al. (2001). The task consists of the creation of two lists of words written with one of two different subsets of letters of the alphabet. We manipulated study time (50, 100, 200, 500 ms per word) of words with different letter probabilistic structure to those originally used by Parkin et al. Letter-based familiarity responding was robust and present even at rates producing otherwise chance performance. A second experi- ment and structural equation modelling led us to interpret the results from the point of view of a theory that takes into account the processing of similarities and differences (Hunt & MacDaniel, (…
Reviewing the impact of problem structure on planning: a software tool for analyzing tower tasks.
2010
Cognitive, clinical, and neuroimaging studies on planning abilities most frequently implement the Tower of London task or one of its variants. Yet, cumulating evidence from a series of experiments suggests that the commonly used approximation of problem difficulty in terms of the minimum number of moves for goal attainment is too coarse a measure for the underlying cognitive operations, and in some cases may be even misleading. Rather, problem difficulty can be more specifically characterized by a set of structural task parameters such as the number and nature of optimal and suboptimal solution paths, the required search depths, the patterns of intermediate and goal moves, goal hierarchies …
The influence of task-irrelevant music on language processing: syntactic and semantic structures.
2011
Recent research has suggested that music and language processing share neural resources, leading to new hypotheses about interference in the simultaneous processing of these two structures. The present study investigated the effect of a musical chord's tonal function on syntactic processing (Experiment 1) and semantic processing (Experiment 2) using a cross-modal paradigm and controlling for acoustic differences. Participants read sentences and performed a lexical decision task on the last word, which was, syntactically or semantically, expected or unexpected. The simultaneously presented (task-irrelevant) musical sequences ended on either an expected tonic or a less-expected subdominant ch…
Boosting working memory with accelerated clocks
2021
Our perception of time varies with the degree of cognitive engagement in tasks. The perceived passage of time accelerates while working on demanding tasks, whereas time appears to drag during boring situations. Our experiment aimed at investigating whether this relationship is mutual: Can manipulated announcements of elapsed time systematically affect the attentional resources applied to a cognitive task? We measured behavioral performance and the EEG in a whole report working memory paradigm with six items of different colors that each had to be reported after a short delay period. The 32 participants were informed about the current time after each 20 trials, while the clock was running at…

Los fundamentos del enfoque cualitativo en la innovación de la enseñanza geográfica
2018
In the paradigmatic and epistemological advances of the 20 th century, the qualitative approach stands out as a reference for building social knowledge, understanding the validity of traditional foundations in geographical education and proposing pedagogical and didactic contributions in the innovation of its educational work. This led us pose the following question: What task do the foundations of the qualitative approach fulfill in the innovation of the teaching of Geography? In this regard, a bibliographical review was carried out to structure a methodology that analyzes the qualitative approach in the teaching of Geography. Likewise, aspects derived from an investigation that claims the…
Summary, Conclusions, and Future Work
2011
In the present work, we addressed two research questions: (1) How does the complexity of a choice task influence decision-making behavior? (2) How can we consider knowledge about decision-making behavior for the design of IIMT? By answering the first research question, we contributed to current theory on decision-making behavior, while the main contribution of addressing the second research question is the development of INTACMATO, an IIMT-prototype for supporting choice decisions.
Dificultades para Codificar, Relacionar y Categorizar Problemas Verbales Algebraicos: dos estudios con estudiantes de secundaria y profesores en form…
2014
En resolución de problemas verbales por transferencia, la activación de problemas ya conocidos que sirvan de guía, depende de las analogías percibidas entre éstos y el problema a resolver. Se desarrollan dos estudios relacionados para analizar en qué características se basan los estudiantes para codificar problemas y detectar sus analogías, en tareas de categorización (sorting). Se utilizaron técnicas cuantitativas y cualitativas combinadas. Primero se analizó cómo los estudiantes de secundaria son influidos por diferentes variables características de problemas de ciencias. Una gran proporción de sujetos no fue capaz de percibir las analogías y diferencias adecuadas entre problemas. El segu…
