Abstract
Children (N = 103, 4- 9 years, 59 females, 84% White, c. 2019) completed visual processing, visual feature integration (color, luminance, motion), and visual search tasks. Contrast sensitivity and feature search improved with age similarly for luminance and color-defined targets. Incidental feature integration improved more with age for color-motion than luminance-motion. Individual differences in feature search (beta = .11) and incidental feature integration (beta = .06) mediated age-related changes in conjunction visual search, an index of visual selective attention. These findings suggest that visual selective attention is best conceptualized as a series of developmental trajectories, within an individual, that vary by an object's defining features. These data have implications for design of educational and interventional strategies intended to maximize attention for learning and memory.

  • Pretraining has recently greatly promoted the development of natural language processing (NLP)
  • We show that M6 outperforms the baselines in multimodal downstream tasks, and the large M6 with 10 parameters can reach a better performance
  • We propose a method called M6 that is able to process information of multiple modalities and perform both single-modal and cross-modal understanding and generation
  • The model is scaled to large model with 10 billion parameters with sophisticated deployment, and the 10 -parameter M6-large is the largest pretrained model in Chinese
  • Experimental results show that our proposed M6 outperforms the baseline in a number of downstream tasks concerning both single modality and multiple modalities We will continue the pretraining of extremely large models by increasing data to explore the limit of its performance

要点】:研究揭示了视觉处理和认知过程如何随着年龄增长共同改善视觉选择性注意,强调了个体发展轨迹的多样性。

方法】:通过视觉处理、视觉特征整合(颜色、亮度、运动)和视觉搜索任务评估了103名4至9岁儿童的视觉选择性注意能力。

实验】:在对比敏感性和特征搜索任务中,使用未具体说明的数据集,发现随年龄增长,儿童在亮度和颜色定义目标的搜索能力上有相似提升,而在颜色-运动特征整合上的改善比亮度-运动更显著,这些个体差异中介了年龄相关的联合视觉搜索变化。
