In industrial problems both the task and environment are often very complex. Local planners are not suucient and, since tasks often involve changing the environment, global planners are limited by time constraints. This paper adopts the notion that pre-processing of the known environment, in order to generate a roadmap, can signiicantly improve on-line path planning tasks. We present results ob...

We describe an integrated strategy for planning, perception, state-estimation and action in complex mobile manipulation domains based on planning in the belief space of probability distributions over states using hierarchical goal regression (pre-image back-chaining). We develop a vocabulary of logical expressions that describe sets of belief states, which are goals and subgoals in the planning...

This paper presents a classroom study that investigated the potential of using touch tabletop technology to support children’s collaborative learning interactions. Children aged 710 worked in groups of three on a collaborative planning task in which they designed a seating plan for their classroom. In the single-touch condition, the tabletop surface allowed only one child to interact with the d...

objectives: the aim of this study was to identify the role of attentional process in postural control using choice reaction time task while changing the visual and proprioceptive cues under difficult balance task (standing on one-leg). methods: this cross-sectional study was conducted by participating 20 young people (22.75±2.29). each subject performed one-leg standing as balance task for each...

25 In this study, we characterized the patterns and timing of cortical activation of 26 visually-guided movements in a task with critical temporal demands. In particular, we 27 investigated the neural correlates of motor planning and on-line adjustments of reaching 28 movements in a choice-reaction time task. High-density EEG (256 electrodes) was 29 recorded in 13 subjects performing reaching m...

Antisaccades produce longer reaction times (RT) than their prosaccade counterparts and this latency increase has been linked to an oculomotor 'pre-setting' that prevents the evocation of a stimulus-driven prosaccade. Moreover, a consequence of oculomotor pre-setting is a lengthening of the RTs associated with a subsequent prosaccade. The goal of the present study was to determine whether the co...

The goal of this project was to examine how training either mental or manual (virtual) rotation, affects performance gains on either a mental or a manual rotation task. In Experiment 1, we examined improvement on a manual rotation task following practice in mental rotation, manual rotation and a control condition. Practice in mental but not manual rotation lead to improved performance on manual...

OBJECTIVES To determine whether adolescents with type 1 diabetes are more at risk for learned helplessness than their healthy peers. METHODS Twenty-three adolescents with diabetes and 25 controls completed a solvable or unsolvable concept formation task. All completed pre- and post-task performance and attribution ratings, and later completed an anagram-solving task to determine if perceived ...

Previously, we showed that the N100 amplitude in long latency auditory evoked potentials (LLAEPs) elicited by pure tone probe stimuli is modulated when the stimuli are delivered during speech movement planning as compared with no-speaking control conditions. Given that we probed the auditory system only with pure tones, it remained unknown whether the nature and magnitude of this pre-speech aud...
