Results from functional and structural neuroimaging studies have also provided important insight into putative neurophysiological mechanisms associated with these functional visual impairments.

We argue that they do so by constantly reconsidering their plan in accordance with their instantaneous evaluation of the circumstances. Doing so allows them to quickly respond to any changes in the environment. The response can be a small adjustment to an ongoing movement, but also diverting the movement if it suddenly becomes evident that moving toward a completely different target is more suitable for some reason.

With a focus on mice, we examine how species-specific visual sampling strategies determine the behavioral relevance of retinal computations and review recent insights into circuits underlying reflexive behaviors, threat detection, prey capture, color vision, and night vision. We also highlight how the behavioral state itself influences retinal processing through direct neuromodulation and pupillary changes, challenging the traditional view of purely feedforward retinal processing in mammals. These findings confirm the retina as a sophisticated computational engine whose circuits have evolved to meet species-specific behavioral demands.

However, multitasking significantly degrades a driver's situational awareness and causes them to overlook or misjudge important aspects of their environment, such as pedestrians, road signs, or other vehicles. It also impairs a driver's ability to visually scan for hazards and process vital information, reducing their capacity to notice and respond to changes on the roadway. Multitasking can also induce inattentional blindness, causing drivers to miss important information directly in their line of sight. Beyond diminished visual attention, multitasking also slows reaction times to detected events, increasing the likelihood and severity of crashes. This article discusses the central role that visual attention plays in a driver's situational awareness, examines common methods for assessing visual attention while driving, and presents an updated review of the SPIDER (scanning, predicting, identification, decision-making, and executing a response) model of driver awareness with a focus on visual distraction.</p>","PeriodicalId":48658,"journal":{"name":"Annual Review of Vision Science","volume":" ","pages":""},"PeriodicalIF":5.0,"publicationDate":"2025-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144054822","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nativists propose that intelligence emerges from innate domain-specific knowledge systems, whereas empiricists propose that intelligence emerges from domain-general systems that learn domain-specific knowledge from experience. We address this debate by reviewing digital twin studies designed to reverse engineer the learning algorithms in newborn brains. In digital twin studies, newborn animals and artificial agents are raised in the same environments and tested with the same tasks, permitting direct comparison of their learning abilities. Supporting empiricism, digital twin studies show that domain-general algorithms learn animal-like object perception when trained on the first-person visual experiences of newborn animals. Supporting nativism, digital twin studies show that domain-general algorithms produce innate domain-specific knowledge when trained on prenatal experiences (retinal waves). We argue that learning across humans, animals, and machines can be explained by a universal principle, which we call space-time fitting. Space-time fitting explains both empiricist and nativist phenomena, providing a unified framework for understanding the origins of intelligence.","PeriodicalId":48658,"journal":{"name":"Annual Review of Vision Science","volume":"210 1","pages":""},"PeriodicalIF":6.0,"publicationDate":"2024-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142260929","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We outline future directions and areas of research that will expand our knowledge of these mechanisms.
