This study explored the effect of input vs. collaborative output tasks on Iranian EFL learners’ grammatical accuracy and their willingness to communicate (WTC). In so doing, the study utilized 3 input (i.e., textual enhancement, processing instruction, and discourse) and 3 collaborative output (i.e., dictogloss, reconstruction cloze task, and jigsaw) tasks and compared their effects on 5 Englis...

One of the central problems in computational neuroscience is to understand how the object-recognition pathway of the cortex learns a deep hierarchy of nonlinear feature detectors. Recent progress in machine learning shows that it is possible to learn deep hierarchies without requiring any labelled data. The feature detectors are learned one layer at a time and the goal of the learning procedure...

We studied changes to the pattern of speech errors as a function of selectively attending to one word in a sequence to learn how attention is implemented in language production. Three hypotheses were tested: (1) attention specifically inhibits the past, (2) attention enhances the activation of the present without affecting the past or the future, and (3) attention decreases priming of the futur...

In this paper, a review of the role of input, output and instruction in second language acquisition is provided. Several pedagogical interventions in grammar instruction (e.g., processing instruction, input enhancement, structured output and collaborative output tasks) are presented and their effectiveness reviewed. A final and overall evaluation is provided at the end of the paper.

The condition of a pressure vessel is normally checked by human operators, which have health and safety risks as well low working efficiency high inspection cost. Visual for vessels can be done an Unmanned Aerial Vehicle (UAV) with the sensing module. Image enhancement techniques image processing are vital in UAV vessels. However, there several issues to overcome visual images captured quality ...

The input enhancement hypothesis proposed by Sharwood Smith (1991, 1993) has stimulated considerable research over the last 15 years. This article reviews the research on textual enhancement of input (TE), an area where the majority of input enhancement studies have aggregated. Methodological idiosyncrasies are the norm of this body of research. Seven major issues appear to be limiting the gene...

Manipulation planning is the problem of finding a sequence robot configurations that involves interactions with objects in scene, e.g., grasping and placing an object, or more general tool-use. To achieve such interactions, traditional approaches require hand-engineering object representations interaction constraints, which easily becomes tedious when complex objects/interactions are considered...
