Recent studies in cognitive psychology have challenged the traditional view that human memory operates as a passive storage system. Instead, researchers now propose that memory is an active reconstructive process, where each recall event involves reinterpreting past experiences through the lens of current knowledge and biases. This paradigm shift has significant implications for eyewitness testimony, as recollections may be unconsciously altered by post-event information. Furthermore, neuroimaging evidence suggests that the brain's prefrontal cortex plays a crucial role in monitoring and verifying the accuracy of retrieved memories, a function that can be impaired under stress. Consequently, legal systems are increasingly adopting stricter protocols for witness interviews to minimize the risk of memory contamination.
