Key to successfully negotiating our environment is our ability to adapt to current settings based on recent experiences and behaviour. Response conflict paradigms (e.g., the Stroop task) have provided evidence for increases in executive control after errors, leading to slowed responses that are more likely to be correct, and less susceptible to response congruency effects. Here we investigate w...

Objectives: Paper and pencil exercises are extensively used to enhance children’s visual perceptual skills, while exercises involving volumetric shapes have been neglected. The present study aimed to develop a combined training package, including volumetric shapes and paper and pencil exercises, and to investigate its effectiveness in strengthening the visual perceptual skills of preschool chil...

Machine translation evaluation methods are highly necessary in order to analyze the performance of translation systems. Up to now, the most traditional methods are the use of automatic measures such as BLEU or the quality perception performed by native human evaluations. In order to complement these traditional procedures, the current paper presents a new human evaluation based on the expert kn...

Spontaneous speech samples from four men diagnosed with apraxia of speech were transcribed to examine the ways in which they attempted to repair their speech errors. The study sought evidence for the presence of production or perceptual constraints in error revision and for the presence of a functional prearticulatory monitor. Three judges independently evaluated the transcriptions and audiotap...

Current perceptual algorithms are error-prone and require the use of additional ad hoc heuristic methods that detect and recover from these errors. In this paper we explore how existing architectural mechanisms in a high-level cognitive architecture like ACT-R can be used instead of such ad hoc measures. In particular, we describe how implicit learning that results from ACT-R’s architectural fe...

We describe a method and an implementation for producing a highly compressed representation of speech, in the order of 40 bps. This compression method uses a speech recognition engine to analyze the speech signal at the morphological level, i.e. the words. The words are then coded using a wordlevel text compression mechanism. After decompression, the speech message is recovered using Text-To-Sp...

The principal aim of the online Mandarin Chinese perceptual test is to understand how learners of Mandarin Chinese identify the language’s four tones and its correlated factors. There are many factors involved in successfully learning a second language. Therefore, aside from a learner’s L1 language and prior experience, his/her attitude and motivation also contribute to L2 learning. That may be...

OBJECTIVE Attention-deficit hyperactivity disorder (ADHD) is a complex developmental neuropsychiatric disorder, characterized by inattentiveness, impulsivity, and hyperactivity. Recent literature suggests a potential core deficit underlying these behaviors may involve inefficient processing when contextual stimulation is low. In order to specify this inefficiency, the aim of the present study w...

Hunrun episodic memory provides a seemingly unlimited storage for everyday experiences, and a retrieval system that allows us to access the experiences with partial activation of their components. The system is believed to consist of afast, temporary storage in the hippocampus,and a slow, long-term storage within the neocortex. Thispaper presents a neural network model of the hippocampal episod...
