Productivity & Study Skills Mindset, Wellbeing & Self-Management Flashcards

24 sample cards from the Mindset, Wellbeing & Self-Management deck

Sampled from the end of the deck, so these are different cards from the ones shown on the syllabus page.

1. Describe the acute (fight-or-flight) stress response.

   A perceived threat activates the sympathetic nervous system and the HPA (hypothalamic-pituitary-adrenal) axis: adrenaline and then cortisol are released, raising heart rate, blood pressure, and glucose availability to prepare the body for immediate action.

2. What does the Yerkes-Dodson law say about arousal and performance?

   Performance follows an inverted-U as a function of arousal: too little arousal gives poor performance (boredom), moderate arousal gives peak performance, and excessive arousal degrades performance (anxiety). The optimal level is lower for complex tasks than for simple ones.

3. Distinguish problem-focused coping from emotion-focused coping (Lazarus & Folkman).

   Problem-focused coping targets the stressor itself (planning, breaking work into steps, seeking help) — best when the situation is controllable. Emotion-focused coping regulates the emotional reaction (breathing exercises, reframing, social support) — best when the stressor cannot be changed.

4. Why is chronic stress harmful to learning and memory?

   Prolonged elevated cortisol impairs hippocampal function (weakening memory formation), biases the brain toward habitual rather than flexible thinking, disrupts sleep, and suppresses immune function — so sustained high stress reduces both encoding and retrieval.

5. Describe the standard Pomodoro Technique work-rest structure.

   Work in focused intervals of $25$ minutes (one 'pomodoro'), then take a $5$-minute break; after every $4$ pomodoros, take a longer break of about $15\text{–}30$ minutes. Each interval has a single defined task and no interruptions.

6. What are ultradian rhythms, and how should they shape study blocks?

   Ultradian rhythms are recurring biological cycles shorter than a day; alertness naturally cycles in periods of roughly $90$ minutes. Working in blocks of about $90$ minutes followed by a real recovery break matches these cycles better than marathon sessions.

7. Why does deliberately scheduling rest improve total output rather than reduce it?

   Attention and willpower are depletable within a session; performance and error rates worsen with continuous time-on-task (vigilance decrement). Planned rest restores attention, consolidates learning, and prevents burnout, so quality-hours matter more than raw hours.

8. What are personal boundaries in the context of study and work?

   Boundaries are explicit limits you set on your time, energy, and availability — e.g., fixed study hours, no messages during deep work, a hard stop in the evening — that protect priority work and recovery from other people's demands.

9. Give a simple three-part formula for saying no assertively.

   1) Acknowledge the request ('Thanks for thinking of me'), 2) Give a clear, brief refusal without over-apologizing ('I can't take this on this week'), 3) Optionally offer an alternative ('I could help after Friday' or suggest someone else). Clear, kind, and firm.

10. How does assertive communication differ from passive and aggressive communication when protecting your time?

    Passive: you sacrifice your needs to avoid conflict (say yes, resent it). Aggressive: you defend your needs by attacking or dismissing others. Assertive: you state your needs and limits directly and respectfully — the only style that protects both the relationship and your priorities.

11. What are the main stages of a sleep cycle, and how long does one cycle last?

    Each cycle lasts about $90$ minutes and moves through NREM stages N1 (light), N2, and N3 (deep slow-wave sleep), followed by REM sleep. A full night contains roughly $4\text{–}6$ cycles, with more deep sleep early in the night and more REM toward morning.

12. Which memory types are consolidated by slow-wave (deep) sleep versus REM sleep?

    Slow-wave sleep chiefly consolidates declarative memories (facts and events, via hippocampal-to-cortical replay); REM sleep supports procedural/skill memory, emotional memory processing, and creative integration of new material.

13. How much sleep do adults need, and what happens to learning when you study while sleep-deprived?

    Adults need about $7\text{–}9$ hours per night. Sleep deprivation impairs the hippocampus's ability to encode new material (learning capacity can drop substantially), weakens attention and working memory, and prevents the overnight consolidation that stabilizes what was studied.

14. Why is an all-nighter before an exam counterproductive?

    It sacrifices the sleep-dependent consolidation of everything studied, while sleep deprivation itself degrades attention, working memory, and retrieval on exam day — so both storage of new material and access to old material suffer.

15. What is the circadian rhythm and what structure controls it?

    The circadian rhythm is the internal biological clock cycling approximately every $24$ hours, regulating sleep-wake timing, hormone release, body temperature, and alertness. It is controlled by the suprachiasmatic nucleus (SCN) in the hypothalamus and is entrained by zeitgebers, chiefly light.

16. How do light and melatonin interact to control sleep timing?

    Darkness triggers the pineal gland to secrete melatonin, promoting sleepiness; light — especially short-wavelength blue light — suppresses melatonin and delays the clock. Hence bright light in the morning advances the rhythm, while screens at night delay sleep onset.

17. What are chronotypes, and how should a student use theirs?

    Chronotypes are stable individual differences in circadian timing — 'larks' (morning types) peak early, 'owls' (evening types) peak late, most people fall in between. Schedule the most demanding cognitive work (problem solving, new material) at your personal alertness peak and routine tasks in your trough.

18. Why does the brain need a steady glucose supply, and which foods support stable focus?

    The brain is only about $2\%$ of body mass but consumes roughly $20\%$ of the body's energy, mainly as glucose. Low-glycemic foods (whole grains, legumes, nuts, protein, vegetables) release glucose steadily, sustaining attention; high-sugar snacks cause a spike-and-crash pattern that impairs concentration.

19. How much dehydration is enough to impair cognition, and what are the effects?

    Even mild dehydration of about $1\text{–}2\%$ of body mass measurably impairs attention, short-term memory, and mood, and increases perceived effort and headaches. Drinking water regularly through the day (not just when thirsty) protects focus.

20. How does caffeine promote wakefulness, and why can afternoon caffeine harm sleep?

    Caffeine blocks adenosine receptors, masking the sleep-pressure signal that accumulates during waking. Its half-life is roughly $5\text{–}6$ hours, so a late-afternoon dose still leaves a substantial fraction in the blood at bedtime, delaying sleep onset and reducing deep sleep.

21. Through what mechanisms does regular aerobic exercise improve learning and memory?

    Aerobic exercise increases brain blood flow and raises BDNF (brain-derived neurotrophic factor), which promotes neurogenesis and synaptic plasticity, especially in the hippocampus. Regular exercisers show better memory, attention, executive function, mood, and stress resilience; guidelines recommend about $150$ minutes of moderate activity per week.

22. What is the difference between focused mode and diffuse mode of thinking (Oakley), and why do you need both?

    Focused mode is deliberate, concentrated attention on a problem using known patterns; diffuse mode is relaxed, background processing that forms broad new connections. Hard problems are solved by alternating: work intensely, then step away (walk, shower, rest) so the diffuse mode can restructure the problem — the basis of the incubation effect.

23. What makes a study break 'strategic', and which break activities restore attention best?

    A strategic break is planned (not a distraction-driven escape), taken before exhaustion, and genuinely detaches from the task. Best restorers: moving, going outdoors or into nature (attention restoration theory), brief naps, hydration, or eyes-closed rest. Worst: switching to social media or email, which keeps directed attention loaded and invites overrun.

24. Distinguish active rest from passive rest, and give when each is the better choice.

    Active rest is low-intensity engaging activity — walking, stretching, light exercise, a hobby, socializing — which boosts circulation, mood, and diffuse-mode thinking; it suits mental fatigue during study days. Passive rest is stillness — sleep, napping, lying down, meditation — which suits physical exhaustion, sleep debt, and overload. Effective recovery mixes both, with sleep as the non-negotiable core.
