Physiological Correlates of Emotion Recognition

Source: Laboratories of Jonas T. Kaplan and Sarah I. Gimbel—University of Southern California The autonomic nervous system (ANS) controls the activity of the body's internal organs and regulates changes in their activity depending on the current environment. The vagus nerve, which innervates many of the internal organs, is an important part of the system. When our brain senses danger, vagal tone is inhibited, leading to a set of changes in the body designed to make us more prepared to fight or...

We present a protocol to explore the relative activation sequence of phonology and semantics in visual word recognition. The results show that consistent with interactive accounts, semantic and phonological representations may be processed interactively, and higher-level linguistic representations may affect early processing.

Revenue Recognition

The revenue recognition principle is a central guideline in accrual accounting that dictates when revenue should be recorded in financial statements. It requires that revenue be recognized when a company satisfies a performance obligation, meaning when it has delivered goods or completed services as agreed in a contract, regardless of when the customer pays. This principle ensures that income is reported in the accounting period in which it is actually earned, providing a more accurate...

Expense Recognition

An expense represents the outflow of economic resources a business uses to generate revenue, encompassing costs such as labor, materials, and services. In accrual accounting, the recording of these costs follows the expense recognition principle, which requires that expenses be recognized in the same accounting period as the related revenues. This alignment ensures that financial statements accurately reflect a business's economic activity during a specific period rather than simply tracking...

Behavioral Tasks for Examining Identity Recognition In Mice

2025
By pairing negatively or positively valenced experiences with individual social targets, we developed behavior tasks for examining the identity recognition of C57BL/6 mice. These tasks allow for the study of mechanisms of social memory of individual social targets in healthy and disease-related mouse models with impaired social cognition.
FAQs
Movement recognition becomes more informative when it considers both spatial and temporal features. Spatial features describe changes in position, orientation, or body configuration, while temporal features capture how those changes develop over time. Together, they help algorithms distinguish movements that may look similar in a single moment but follow different patterns across a sequence of observations.
These sensors provide different forms of evidence about physical motion. Cameras observe visual changes, accelerometers and gyroscopes capture motion-related measurements, and depth devices contribute information about spatial configuration. Combining such inputs can give an engineering system a broader basis for interpretation than relying on one observation type alone, supporting recognition across human, robotic, and industrial settings.
Learned patterns give the classification stage a reference for interpreting new observations. Signal-processing methods first help extract relevant spatial and temporal features, after which machine-learning algorithms compare those features with patterns acquired during learning. The system can then identify a movement or activity, making recognition more systematic and enabling responsive control or quantitative monitoring.
A typical workflow begins by collecting motion observations with suitable sensors, followed by signal processing to extract spatial and temporal features. Machine-learning algorithms then compare those features with learned patterns and classify the observed movement or activity. The resulting information can be connected to a control, monitoring, or interaction system, depending on the engineering objective.
Engineers may choose movement recognition when a system must respond to physical actions or track how motion changes over time. The approach supports human-computer interaction, robotics, wearable devices, rehabilitation systems, surveillance, and industrial automation. Its value differs by setting: it can enable more natural control, support monitoring, or provide information for machine responsiveness and safety.
In rehabilitation, recognized movement can provide quantitative data for monitoring human movement and performance. In industrial automation, the same general approach can help systems interpret motion and respond more effectively. Across both contexts, reliable recognition connects observed physical activity with engineering decisions, supporting performance assessment, safety monitoring, or automated operation without changing the underlying sensing and classification principles.
