Seeing the fours before the threes: Investigating numerical signatures with hierarchical navon stimuli
Anchoring bias in mental arithmetic
Invariant representations in abstract concept grounding – the physical world in grounded cognition
Grounded cognition states that mental representations of concepts consist of experiential aspects. For example, the concept “cup” consists of the sensorimotor experiences from interactions with cups. Typical modalities in which concepts are grounded are: The sensorimotor system (including interoception), emotion, action, language, and social aspects. Here, we argue that this list should be expanded to include physical invariants (unchanging featu…

Spontaneous grip force fluctuations mirror semantic numerical magnitude processing: Larger numbers elicit larger forces
This study investigated the relationship between semantic numerical magnitudes and motor magnitudes. We asked whether the processing of numbers can affect motor behavior such as the size of numbers affecting the size of motor actions. For this, we recorded continuous grip force fluctuations from 43 healthy adults during a symbolic magnitude comparison task. We found that numbers induced spontaneous grip force fluctuations during number processing…
Number to me, space to you: Joint representation of spatial-numerical associations
Recent work has shown that number concepts activate both spatial and magnitude representations. According to the social co-representation literature which has shown that participants typically represent task components assigned to others together with their own, we asked whether explicit magnitude meaning and explicit spatial coding must be present in a single mind, or can be distributed across two minds, to generate a spatial-numerical congruenc…
Abstract concepts: External influences, internal constraints, and methodological issues
There is a longstanding and widely held misconception about the relative remoteness of abstract concepts from concrete experiences. This review examines the current evidence for external influences and internal constraints on the processing, representation, and use of abstract concepts, like truth, friendship, and number . We highlight the theoretical benefit of distinguishing between grounded and embodied cognition and then ask which roles do pe…

Spatial-numerical associations without a motor response? Grip force says ‘Yes’
In numerical processing, the functional role of Spatial-Numerical Associations (SNAs, such as the association of smaller numbers with left space and larger numbers with right space, the Mental Number Line hypothesis) is debated. Most studies demonstrate SNAs with lateralized responses, and there is little evidence that SNAs appear when no response is required. We recorded passive holding grip forces in no-go trials during number processing. In Ex…
Systematic spatial distortion of quantitative estimates
Magnitude estimation has been studied since the beginnings of scientific psychology and constitutes a fundamental aspect of human behavior. Yet, it has apparently never been noticed that estimates depend on the spatial arrangement used. We tested 167 adults in three experiments to show that the spatial layout of stimuli and responses systematically distorts number estimation, length production, and weight reproduction performance. The direction o…
Tactile Interaction with a Humanoid Robot: Effects on Physiology and Subjective Impressions
This study investigated how touching and being touched by a humanoid robot affects human physiology, impressions of the interaction, and attitudes towards humanoid robots. 21 healthy adult participants completed a 3 (touch style: touching , being touched , pointing ) × 2 (body part: hand vs buttock ) within-subject design using a Pepper robot. Skin conductance response (SCR) was measured during each interaction. Perceived impressions of the inter…

The Cultural Number Line: A Review of Cultural and Linguistic Influences on the Development of Number Processing
Approximate processing of numerosities is a universal and preverbal skill, while exact number processing above 4 involves the use of culturally acquired number words and symbols. The authors first review core concepts of numerical cognition, including number representation in the brain and the influential view that numbers are associated with space along a “mental number line.” Then, they discuss how cultural influences, such as reading direction…
Finger Counting Habits in Middle Eastern and Western Individuals: An Online Survey
The current study documents the presence of cultural differences in the development of finger counting strategies. About 900 Middle Eastern (i.e., Iranian) and Western (i.e., European and American) individuals reported in an online survey how they map numbers onto their fingers when counting from 1 to 10. The analysis of these bimanual counting patterns revealed clear cross-cultural differences in the hand and finger starting preferences: While m…
Cultural Effects on the Mental Number Line
This special issue is the result of a workshop on the cultural effects on the mental number line held in York (U.K.) in July 2009. The workshop was funded by the Experimental Psychology Society (www.eps.ac.uk) and the European Society for Cognitive Psychology (www.escop.eu), and we thank both organisations for sponsoring the event. The aims of the workshop were to bring together experimental psychologists who study effects of cultural variables o…

Embodied Language: A Review of the Role of the Motor System in Language Comprehension
A growing body of research suggests that comprehending verbal descriptions of actions relies on an internal simulation of the described action. To assess this motor resonance account of language comprehension, we first review recent developments in the literature on perception and action, with a view towards language processing. We then examine studies of language processing from an action simulation perspective. We conclude by discussing several…

Selective Reaching: Distracter Effects on Movement Kinematics as a Function of Target—Distracter Separation
The authors investigated distracter effects on the kinematics of reaching movements to determine when during reaching responses (reaction time, time to peak velocity, time after peak velocity, or peak velocity) distracter interference occurred and how target-distracter separation affected the locus of interference. Participants moved a pen on a digitizing tablet toward a target appearing with or without a distracter. With a small target-distracte…
Can we correctly perceive the reaching range of others
Little is known about our ability to predict the motor capacities of other people. This study explored how observers perceive the reaching range of another person by asking them to judge the reachability of a moving object. Experiments 1 and 2 found that observers overestimated the reaching ranges of both short and tall people. Estimates were larger when objects moved towards rather than away from the person. Experiment 3 showed that perceived re…
