概括
凝视追踪在整个童年和成年时期都在发展,在年轻成人时的精度达到顶峰,在老年时略有下降. 个体差异是由学生角度估计的计算模型解释的,并且与向量跟踪和视角技能有关.
科学领域:
- 发展心理学是发展心理学.
- 认知神经科学是一种认知神经科学.
- 社会的认知社会认知.
背景情况:
- 凝视跟踪对于社会认知能力至关重要,比如推断知识.
- 以前的研究集中在婴儿期的群体水平发展上,对后来的发展和个体差异的理解有限.
研究的目的:
- 为了研究凝视在整个生命周期中的发展轨迹.
- 通过使用计算模型,探索视线跟踪中个体差异的来源.
- 检查凝视追随,矢量追随和视角采用之间的关系.
主要方法:
- 研究1:对3至80岁的儿童 (N=718) 的表现后视线的横截面研究.
- 研究2:开发一种计算认知模型,以解释眼神跟踪的个体差异 (N=110).
- 研究3:对应性研究,检查儿童的注视跟踪与矢量跟踪和思维理论任务 (N=102).
主要成果:
- 从学龄前期开始,表现后的目光显著改善,并在成年时保持稳定,在老年时略有下降.
- 一个计算模型成功地解释了个体差异,模拟了眼神视线,然后估计了瞳孔角和视线向量.
- 凝视追随与非社会向量追随和2级视角采用相关,但不是其他思维理论任务.
结论:
- 凝视追踪显示了婴儿期以外的长期发展过程,与年龄相关的精度变化.
- 凝视跟踪的个体差异可以通过视觉感知计算模型进行有意义的解释.
- 凝视跟踪与特定的社会认知技能相关,如视角采用和非社会空间推理,突出了核心认知过程的相互作用.

Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...

In cross-sectional research, a researcher compares multiple segments of the population at the same time. If they were interested in people's dietary habits, the researcher might directly compare different groups of people by age. Instead of following a group of people for 20 years to see how their dietary habits changed from decade to decade, the researcher would study a group of 20-year-old individuals and compare them to a group of 30-year-old individuals and a group of 40-year-old...

If you want to understand how behavior occurs, one of the best ways to gain information is to simply observe the behavior in its natural context. However, people might change their behavior in unexpected ways if they know they are being observed. How do researchers obtain accurate information when people tend to hide their natural behavior? As an example, imagine that your professor asks everyone in your class to raise their hand if they always wash their hands after using the restroom. Chances...
