Imagine your brain is like a busy office. When you're stressed all the time, it's like the fire alarm keeps ringing, even when there's no actual fire. This constant noise makes it really hard for the "workers" in your brain to do their jobs properly. When that "fire alarm" is constantly blaring, your brain struggles to properly file away new information. So, learning new things or remembering recent events becomes tricky, like trying to read a book in a noisy room. It also makes it harder to find old memories, so recalling things you already knew can be tough. Sometimes, it even makes your brain focus *too much* on scary or negative memories, like constantly checking for smoke when there isn't any. And when it comes to making decisions, that constant alarm makes your brain want to act fast, without thinking things through. It's like grabbing the first thing you see in a panic, instead of carefully choosing what you need. You might make quick, impulsive choices or stick to old, familiar ways of doing things, even if they're not the best, because your brain is too overwhelmed to explore new options.

Chronic stress significantly impairs cognitive functions, particularly memory. It can lead to structural changes in the brain, such as atrophy of the hippocampus, which is crucial for explicit memory formation and recall. This results in reduced capacity for remembering facts, events, and even the details of past experiences, while also hindering working memory—the ability to hold and manipulate information in the short term. This degradation of memory directly influences decision-making. Individuals under chronic stress often exhibit a greater reliance on System 1 thinking—fast, intuitive, and heuristic-driven—rather than System 2—slow, deliberate, and analytical. They may struggle to fully process new information, recall relevant past outcomes, or project future consequences, leading to choices that are predictably less rational or optimal from an economic standpoint. In the context of charitable giving, chronic stress can introduce distinct biases. A donor experiencing chronic stress might be less able to recall the impact of previous donations, evaluate the efficacy of a charity's programs, or engage in the future-oriented thinking often required for sustained prosocial behavior. This cognitive load can lead to impulsive giving based on immediate emotional appeals, or conversely, a reduction in giving as individuals prioritize

Chronic stress profoundly impacts memory function through its sustained physiological effects on the brain. Elevated levels of glucocorticoids, such as cortisol, resulting from chronic HPA axis activation, negatively influence the hippocampus and prefrontal cortex. These critical brain regions are essential for memory encoding, retrieval, and working memory. Specifically, chronic stress can reduce synaptic plasticity in the hippocampus and compromise the structural integrity of the prefrontal cortex, leading to difficulties in forming new memories, accessing existing ones, and maintaining cognitive flexibility. Regarding choices, chronic stress significantly alters decision-making processes by shifting neural resource allocation. Individuals under chronic stress often exhibit a reduced capacity for deliberate, goal-directed reasoning, typically mediated by the prefrontal cortex. Instead, there is an increased reliance on habit-based or emotionally driven decision-making pathways, often involving the striatum. This can manifest as increased impulsivity, a preference for immediate rewards over long-term benefits, and a narrowed attentional focus that limits the consideration of alternative solutions, ultimately compromising adaptive choice selection.
