Mental arithmetic is characterised by a tendency to overestimate addition and to underestimate subtraction results: the operational momentum effect. Here, motivated by contentious explanations of this effect, we developed and tested an arithmetic heuristics and biases model that predicts reverse OM due to cognitive anchoring effects. Participants produced bi-directional lines with lengths corresponding to the results of arithmetic problems. In two experiments, we found regular OM with zero problems but reverse OM with non-zero problems. In a third experiment, we tested (...) the prediction of our model. Our results suggest the presence of at least three competing biases in mental arithmetic: a more-or-less heuristic, a sign-space association and an anchoring bias. We conclude that mental arithmetic exhibits shortcuts for decision-making similar to traditional domains of reasoning and problem-solving. (shrink)
TEST is a novel taxonomy of knowledge representations based on three distinct hierarchically organized representational features: Tropism, Embodiment, and Situatedness. Tropic representational features reflect constraints of the physical world on the agent's ability to form, reactivate, and enrich embodied (i.e., resulting from the agent's bodily constraints) conceptual representations embedded in situated contexts. The proposed hierarchy entails that representations can, in principle, have tropic features without necessarily having situated and/or embodied features. On the other hand, representations that are situated and/or embodied (...) are likely to be simultaneously tropic. Hence, although we propose tropism as the most general term, the hierarchical relationship between embodiment and situatedness is more on a par, such that the dominance of one component over the other relies on the distinction between offline storage versus online generation as well as on representation-specific properties.

Small numbers are spontaneously associated with left space and larger numbers with right space (the SNARC effect), for example when classifying numbers by parity. This effect is often attributed to reading habits but a causal link has so far never been documented. We report that bilingual Russian-Hebrew readers show a SNARC effect after reading Cyrillic script (from left-to-right) that is significantly reduced after reading Hebrew script (from right-to-left). In contrast, they have similar SNARC effects after listening to texts in either (...) language. These results support the view that spatially directional scanning habits contribute to the spatial association of numbers but also emphasize its flexibility. (shrink)
We assessed the automaticity of spatial-numerical and spatial-musical associations by testing their intentionality and load sensitivity in a dual-task paradigm. In separate sessions, 16 healthy adults performed magnitude and pitch comparisons on sung numbers with variable pitch. Stimuli and response alternatives were identical, but the relevant stimulus attribute (pitch or number) differed between tasks. Concomitant tasks required retention of either color or location information. Results show that spatial associations of both magnitude and pitch are load sensitive and that the spatial (...) association for pitch is more powerful than that for magnitude. These findings argue against the automaticity of spatial mappings in either stimulus dimension. (shrink)
Embodied cognition postulates a bi-directional link between the human body and its cognitive functions. Whether this holds for higher cognitive functions such as problem solving is unknown. We predicted that arm movement manipulations performed by the participants could affect the problem-solving solutions. We tested this prediction in quantitative reasoning tasks that allowed two solutions to each problem. In two studies with healthy adults, we found an effect of problem-congruent movements on problem solutions. Consistent with embodied cognition, sensorimotor information gained via (...) right or left arm movements affects the solution in different types of problem-solving tasks. (shrink)
ion is instrumental for our understanding of how numbers are cognitively represented. We propose that the notion of abstraction becomes testable from within the framework of simulated cognition. We describe mental simulation as embodied, grounded, and situated cognition, and report evidence for number representation at each of these levels of abstraction.
This two-volume set provides a comprehensive overview of the multidisciplinary field of Embodied Cognition. With contributions from internationally acknowledged researchers from a variety of fields, _Foundations of Embodied Cognition_ reveals how intelligent behaviour emerges from the interplay between brain, body and environment. Covering early research and emerging trends in embodied cognition, Volume 1 _Perceptual and Emotional Embodiment_ is divided into four distinct parts, bringing together a number of influential perspectives and new ideas. Part one opens the volume with an overview (...) of theoretical perspectives and the neural basis of embodiment, before part two considers body representation and its links with action. Part three examines how actions constrain perception of the environment, and part four explores how emotions can be shaped and structured by the body and its activity. Building on the idea that knowledge acquisition, retention and retrieval are intimately interconnected with sensory and motor processes, _Foundations of Embodied Cognition_ is a landmark publication in the field. It will be of great interest to researchers and advanced students from across the cognitive sciences, including those specialising in psychology, neuroscience, intelligent systems and robotics, philosophy, linguistics and anthropology.

Lee and Schwarz suggest that separation is the grounded procedure underlying cleansing effects in different psychological domains. Here, we interpret L&S's account from a hierarchical view of cognition that considers the influence of physical properties and sensorimotor constraints on mental representations. This approach allows theoretical integration and generalization of L&S's account to the domain of formal quantitative reasoning.
The reliable covariation between numerosity and spatial extent is considered as a strong constraint for inferring the successor principle in numerical cognition. We suggest that children can derive a general number concept from the (experientially) infinite succession of spatial positions during object manipulation.
This two-volume set provides a comprehensive overview of the multidisciplinary field of Embodied Cognition. With contributions from internationally acknowledged researchers from a variety of fields, Foundations of Embodied Cognition reveals how intelligent behaviour emerges from the interplay between brain, body and environment. Drawing on the most recent theoretical and empirical findings in embodied cognition, Volume 2 _Conceptual and Interactive Embodiment_ is divided into four distinct parts, bringing together a number of influential perspectives and new ideas. Part one introduces the field (...) of embodied language processing, before part two presents recent developments in our understanding of embodied conceptual understanding. The final two parts look at the applied nature of embodied cognition, exploring the embodied nature of social co-ordination as well as the emerging field of artificial embodiment. Building on the idea that knowledge acquisition, retention and retrieval are intimately interconnected with sensory and motor processes, _Foundations of Embodied Cognition_ is a landmark publication in the field. It will be of great interest to researchers and advanced students from across the cognitive sciences, including those specialising in psychology, neuroscience, intelligent systems and robotics, philosophy, linguistics and anthropology.

What are the underlying processes that enable human beings to recognize a happy face? Clearly, featural and configural cues will help to identify the distinctive smile. In addition, the motivational state of the observer will influence the interpretation of emotional expressions. Therefore, a model accounting for emotion recognition is only complete if bottom-up and top-down aspects are integrated.
Social robots are increasingly used in different areas of society such as public health, elderly care, education, and commerce. They have also been successfully employed in autism spectrum disorders therapy with children. Humans strive to find in them not only assistants but also friends. Although forms and functionalities of such robots vary, there is a strong tendency to anthropomorphize artificial agents, making them look and behave as human as possible and imputing human attributes to them. The more human a robot (...) looks, the more appealing it will be considered by humans. However, this linear link between likeness and liking only holds to the point where a feeling of strangeness and eeriness emerges. We discuss possible explanations of this so-called uncanny valley phenomenon that emerges in human–robot interaction. We also touch upon important ethical questions surrounding human–robot interaction in different social settings, such as elderly care or autism spectrum disorders therapy. (shrink)
The study has two objectives: to introduce grip force recording as a new technique for studying embodied numerical processing; and to demonstrate how three competing accounts of numerical magnitude representation can be tested by using this new technique: the Mental Number Line, A Theory of Magnitude and Embodied Cognition account. While 26 healthy adults processed visually presented single digits in a go/no-go n-back paradigm, their passive holding forces for two small sensors were recorded in both hands. Spontaneous and unconscious grip (...) force changes related to number magnitude occurred in the left hand already 100–140 ms after stimulus presentation and continued systematically. Our results support a two-step model of number processing where an initial stage is related to the automatic activation of all stimulus properties whereas a later stage consists of deeper conscious processing of the stimulus. This interpretation generalizes previous work with linguistic stimuli and elaborates the timeline of embodied cognition. We hope that the use of grip force recording will advance the field of numerical cognition research. (shrink)
Sex robots are humanoid robots with artificial intelligence, designed to interact sexually with humans. They have received much attention in recent discussions about technology, human relationships and the future of human sexuality. Based on available evidence so far, this outlook aims to give tentative answers to two fundamental questions surrounding the topic of human–robot intimate relationships. First, whether intelligent humanoid robots are technologically ready to be our intimate partners. Second, whether humans are ready to accept the idea of developing intimate (...) relationships with robots, and how far we have engaged and will engage in such activity. We highlight the importance of a scientific transdisciplinary approach to the study of human sexuality in the twenty-first century. (shrink)
