概括

语义信息显著影响对象检测. 这项研究使用漂移扩散建模来表明,有效的标签增强了证据的积累,而无效的标签则造成了不确定性,影响了对象识别的决策过程.

科学领域:

认知心理学认知心理学
神经科学是一个神经科学.
计算建模计算建模

背景情况:

由单词激活的语义在对象检测中起着至关重要的作用.
之前的研究使用对象位置的正确报告在双部分显示器中索引了对象检测.

研究的目的:

阐明由语义信息影响的对象检测背后的认知机制.
调查有效和无效标签如何影响对象识别任务期间的证据积累.

主要方法:

利用漂移扩散建模 (DDM) 来分析来自对象检测实验的行为数据.
在测试显示之前,使用了带有熟悉对象和操纵标签 (有效和无效) 的双边显示器.

主要成果:

有效的标签增加了朝着正确决策的漂移率 (信号与噪声比率).
不有效的标签,特别是来自同一个上级类别的标签,提高了决策门,表明需要更多证据.
无效标签减少了有效标签对证据积累的促进作用.

Instinctive Drift

Instinctive Drift

Instinctive drift refers to the tendency of animals to revert to their innate behaviors despite repeated reinforcement. Breland and Breland demonstrated this concept in an experiment with a raccoon. The raccoon was trained to pick up two coins and place them in a container in exchange for food. Initially, the raccoon learned to associate the coins with food, making them a conditioned stimulus or a substitute for food. However, over time, the raccoon became less willing to put the coins into the...
