视觉感知学习是由视觉感知经验引起的长期的绩效提高。特征的任务相关VPL来自于在与任务相关的特征上训练任务。任务无关VPL是由于暴露于与训练任务无关的特征而产生的。至少有两个严重的问题。首先,与任务相关的VPL改变了信息加工的哪个阶段是有争议的。第二,没有一个模型能够同时解释任务相关和任务无关的VPL。在这里,我们提出了一个双可塑性模型,其中有基于特征的可塑性,这是一个学习功能的表示和基于任务的可塑性,这是在训练任务的处理变化的变化。虽然这两种类型的可塑性下的任务相关的VPL,只有基于特征的可塑性下的任务无关的VPL。这个模型提供了一个新的综合框架,在其中可以解释明显矛盾的结果。
Visual perceptual learning (VPL) is long-term performance increase resulting from visual perceptual experience. Task-relevant VPL of a feature results from training of a task on the feature relevant to the task. Task-irrelevant VPL arises as a result of exposure to the feature irrelevant to the trained task. There are at least two serious problems. First, which stage of information processing is changed in association with task-relevant VPL is controversial. Second, no model has ever explained both task-relevant and task-irrelevant VPL. Here we propose a dual plasticity model, in which there are feature-based plasticity that is a change in a representation of the learned feature and task-based plasticity that is a change in processing of the trained task. While the two types of plasticity underlie task-relevant VPL, only feature-based plasticity lies under task-irrelevant VPL. This model provides a new comprehensive framework in which apparently contradictory results could be explained.
