O’Keefe and Nadel distinguish two paradigms for navigation, the “locale system” for map-based navigation and the “taxon (behavioral orientation) system” for route navigation. This paper models the taxon system, the map-based system, and their interaction; and argues that the map-based system involves the interaction of hippocampus with other systems. We relate taxes to the notion of an affordan...

We study how a robot can link concepts represented by adjectives and nouns in language with its own sensorimotor interactions. Specifically, an iCub humanoid robot interacts with a group of objects using a repertoire of manipulation behaviors. The objects are labeled using a set of adjectives and nouns. The effects induced on the objects are labeled as affordances, and classifiers are learned t...

BACKGROUND Although poor health conditions and decreased developmental levels have been investigated in migrant children, no study in China has focused on these children's individual motor development. OBJECTIVES This study aims to explore the prevalence of motor impairment in Chinese migrant children and to determine the contributory factors. PATIENTS AND METHODS In this cross-sectional st...

Although information is sparse, research suggests that affordances in the home provide essential resources that promote motor and cognitive skills in young children. The present study assessed over time, the association between motor affordances in the home and infant motor and cognitive behavior. Thirty-two (32) infants were assessed for characteristics of their home using the Affordances in t...

This research questions how social media use affords new forms of organizing and collective engagement. The concept of connective action has been introduced to characterize such new forms of collective engagement in which actors coproduce and circulate content based upon an issue of mutual interest. Yet, how the use of social media actually affords connective action still needed to be investiga...

Inspired in part by Gibson's (1979) ecological approach to perception, current neurocognitive theories of action suggest that the simple viewing of an object can automatically elicit motor programs for specific acts. However, the degree to which such affordances should be considered truly automatic is unknown. Here we explored the generation of motor plans afforded by pairs of cue objects that ...

Location-based services assist people in their decision-making during the performance of tasks in space. They do not consider the user’s individual preferences, time constraints, and possible subtasks to be performed. In order to account for these important aspects, a user centered spatio-temporal theory of location-based services is required. We propose such a theory by combining classical tim...

Robotic agents often map perceptual input to simplified representations that do not reflect the complexity and richness of the world. This simplification is due in large part to the limitations of planning algorithms, which fail in large stochastic state spaces on account of the well-known “curse of dimensionality.” Existing approaches to address this problem fail to prevent autonomous agents f...
