Understanding the Mind

The availability heuristic is the tendency to judge the likelihood of an event based on how easily examples come to mind. Vivid or recent events feel more common than they actually are.

Arousal refers to the degree to which the body and mind are activated and alert — ranging from deep sleep at the lowest end to extreme excitement or panic at the highest end.

Memory lasts longer when learning is spread out over time with intervals, rather than cramming everything at once.

Interference Theory explains how memories can disrupt each other, making it harder to recall specific information. The more similar memories you have, the more likely they are to get mixed up.

Sensation is the process by which sensory organs — such as the eyes, ears, nose, tongue, and skin — detect external stimuli. It is the first gateway through which information about the world enters our minds, serving as the starting point for perception and awareness.

Sensory memory stores information received through the senses for a very brief period (1–3 seconds). It is the first gateway of memory, and only information that receives attention passes on to the next stage.

Gratitude is the feeling of noticing and appreciating the good things in your life. Even small moments of thankfulness can create great happiness.

Emotional labor is when your job or situation requires you to express feelings that differ from what you actually feel inside.

Emotional granularity is the ability to differentiate emotions with precision — going beyond 'happy' or 'sad' to identify exactly what you're feeling.

A defense in which painful feelings or memories are pushed out of awareness without realizing it. Unlike emotional suppression, where you notice a feeling and hold it back, repression happens unconsciously.

Feeling an emotion but holding it in so it doesn't show in your face, words, or actions. It can help in the moment, but as a habit it tends to wear down both mind and body.

Affective forecasting is the psychological process of predicting how future events will make us feel, including the intensity and duration of those emotions.

A model that maps emotions using two dimensions: pleasantness and energy level.

The ability to notice what emotions you are feeling in the moment. It's the first step in emotional regulation.

Emotional contagion is when another person's emotions transfer over to you. Feelings really are contagious!

The ability to recognize, experience, and manage how emotions are expressed. It involves learning to coexist with emotions in a healthy way, rather than suppressing them.

Emotion regulation strategies are the various psychological methods we use to influence which emotions we feel, when we feel them, and how intensely we experience and express them. Healthy emotion regulation is a cornerstone of mental stability and well-being.

It means showing your feelings through words or actions. Healthy expression deepens your relationships with others.

A mental shortcut in which people make judgments based on their current emotions or gut feelings rather than logical analysis, as proposed by Paul Slovic.

Emotional memory is the phenomenon where experiences accompanied by strong emotions are stored more vividly and for longer than ordinary memories. Emotions such as joy, sadness, and fear play a role in strengthening how memories are encoded.

Emotional reasoning means judging reality based on how you feel. It's the sense that 'I feel anxious, so something must be dangerous.'

A tendency to be receptive to new experiences, ideas, and imagination. It reflects curiosity and creativity.

A theory that people understand and predict the world through their own unique system of concepts (constructs). Each person is seen as a kind of scientist who interprets the world in their own way.

Personalization is the tendency to blame yourself for things that have nothing to do with you.

Gestalt Principles are the laws of perception describing how our minds automatically organize individual elements into meaningful wholes. Based on the idea that 'the whole is greater than the sum of its parts,' these principles explain the fundamental way our minds make sense of the world.

Decision paralysis is the inability to make a choice due to excessive analysis, fear of making the wrong decision, or having too many options.

Decision fatigue is the phenomenon where making many decisions throughout the day causes your judgment to deteriorate and leaves you mentally exhausted.

An age-old debate in psychology about whether our actions are determined by pre-existing causes, or whether we can freely make our own choices.

The ability to use knowledge and skills built up through years of learning and experience — and it actually grows stronger as you get older.

A reasoning error in which two events occurring together seem more likely than one of those events alone.

Liminality is the psychological state of being 'in between' — having left a previous stage of life but not yet arrived at the next one.

A powerful feeling of wonder in front of something vast, beautiful, or beyond the ordinary.

The planning fallacy is the tendency to optimistically predict that a task will be completed faster and more easily than it actually will be. It's an extremely common cognitive bias that nearly everyone experiences at some point.

A fixed mindset is the belief that abilities are innate and cannot be changed. It's the thinking of 'This is just who I am.'

Emotional exhaustion that can happen when you spend a long time caring about other people’s pain.

A psychological theory proposing that much of human behavior is driven by the need to manage the deep terror of death — through self-esteem and cultural worldview as psychological buffers.

It's when you draw broad conclusions about all situations based on just one or two experiences.

Observational bias is when an observer's expectations, beliefs, and experiences influence what they notice and how they interpret results. We tend to see what we already expect or want to see.

The idea that remembering is an active reconstruction of the past, not an exact replay of a recording.

Attribution style is the habitual pattern a person uses to explain why good or bad events happen to them — whether they blame themselves or circumstances, see causes as permanent or temporary, and view effects as far-reaching or limited.

Longing is the feeling of missing a cherished person or time that is no longer close to you.

The Shadow is the hidden, darker side of yourself that you deny or don't want to acknowledge. It contains the parts of you that feel 'not like me.'

The power to maintain passion and perseverance toward long-term goals. It can matter more than talent.

Positive affect is a collective term for good feelings like joy, pleasure, and satisfaction.

Positive illusions refer to the tendency to view yourself, your future, and your sense of control in a slightly more favorable light than reality warrants. A moderate level of positive illusions can actually support good mental health.

Expectancy Theory suggests that a person's motivation to act depends on their belief that effort will lead to good outcomes. The core of motivation lies in trusting that hard work produces results, and that those results will lead to meaningful rewards.

Mood congruence is the tendency to more easily remember and notice information that matches your current emotional state. When you're sad, sad memories come to mind more readily; when you're happy, joyful memories feel more vivid.

Memory bias is when your memories get distorted by your current emotions or beliefs. Our memories are much less accurate than we think.

A strategy or technique used to remember information more easily. There are many methods, including songs, acronyms, and image association.

Memory is not stored like a precise video recording — instead, it is actively rebuilt each time we recall it, shaped by our current knowledge, emotions, and context. Our memories are like living stories that continue to change over time.
