Robert M. Rioux & Suprita Jharimune, Pennsylvania State University, University Park, PA Among the many hazards present in the laboratory, electrical hazards are one of the most common we must be cognizant of since most of the laboratory equipment we use requires electricity for operation. Improper handling or operation of electrical devices might lead to electric shock with the potential risk of injury or even death. Electric sparks can lead to fire or explosion (since many flammable...

Survey Safety

Surveying near highways, rough terrain, or power lines involves significant risks. Working along highways is particularly dangerous and requires the use of warning signs and flagmen. It is safest to avoid working directly on roads and use offsets whenever possible. When highway work is unavoidable, it must follow all safety guidelines. Surveyors should wear bright clothing, such as orange reflective vests, to ensure visibility to motorists, coworkers, and hunters. In construction zones, wearing...

Source: Ali Bazzi, Department of Electrical Engineering, University of Connecticut, Storrs, CT. Electric machines and power electronics experiments involve electrical currents, voltages, power, and energy quantities that should be handled with extreme diligence and care. These may include three-phase AC voltage (208 V, 230 V, or 480 V), up to 250 V DC voltages, and currents that can reach 10 A. Electrocution occurs when an electrical path is established through the body with very low currents...

Margin of Safety

The margin of safety is a financial metric that quantifies the extent to which actual or projected sales exceed the break-even point. It serves as an indicator of operational risk by showing how much sales can decline before a firm begins to incur losses. This measure is crucial for assessing a company's financial buffer and guiding strategic decisions related to pricing, budgeting, and risk management.A higher margin of safety reflects a stronger financial position, indicating that the company...

An Introduction to Learning and Memory
0 Views •
2023
Learning is the process of acquiring new information and memory is the retention or storage of that information. Different types of learning, such as non-associative and associative learning, and different types of memory, such as long-term and short-term memory, have been associated with human behaviors. Studying these components in detail helps behavioral scientists understand the neural mechanisms behind these two complex phenomena. JoVE's overview on learning and memory introduces common...
FAQs
The critical learning signal is not simply that a stimulus is neutral; it is that the cue reliably occurs without the aversive outcome that was expected. Repeated safe pairings can therefore change the cue’s behavioral meaning, allowing it to support reduced defensive responding. Reliability is important because inconsistent experiences provide weaker information about whether danger has truly passed.
Safety learning can be tied to a situation rather than only to an individual cue. When a context is repeatedly experienced as safe, that setting can support lower learned fear and less avoidance. This contextual aspect matters in changing environments, because behavior depends not only on what signal is present but also on where the individual encounters it.
Safety learning and fear extinction are closely related in behavioral models, but they emphasize different explanatory questions. Safety learning focuses on how cues, contexts, or actions acquire information about the absence of danger. Fear extinction concerns the reduction of learned fear during safe exposure. Considering both helps explain why avoidance may decrease when threat is no longer present.
A basic research sequence starts by identifying a cue, context, or action associated with an expected threat, then providing repeated experiences in which the expected aversive outcome does not occur. Researchers can examine whether subsequent exposure to that cue or context is accompanied by less learned fear or avoidance. This sequence links experience, changed behavioral meaning, and adaptive responding.
When safe exposure is followed by reduced learned fear or avoidance, the pattern is consistent with safety learning because the individual is responding differently to a situation that is no longer harmful. In behavioral research, this outcome helps connect repeated experience with adaptation, especially when environments change and formerly threatening conditions become safe.
In anxiety-related research, safety learning helps explain how defensive behavior can be recalibrated when situations that once seemed threatening are no longer harmful. The framework connects repeated safe experience with reductions in learned fear and avoidance, and it supports interventions designed to strengthen adaptive responses. Its value lies in linking environmental change to behavioral regulation.
