POST (Power On Self Test)

Overview

POST is a daily cognitive self-test and training system within MeatSpace. It covers five cognitive domains: Math, Memory, Wordplay, Verbal Agility, and Imagination. Sessions are designed to take ~5 minutes and balance testing with active training — teaching techniques and building skills, not just measuring them.

Cognitive Domains

1. Mental Math (existing)

  • Doubling Chain — sequential doubling from a seed number
  • Serial Subtraction — countdown by a fixed subtrahend (e.g., 100 - 7 - 7 - 7...)
  • Multiplication — random N-digit multiplication problems
  • Powers — base^exponent calculations
  • Estimation — approximate large arithmetic within tolerance

2. Memory (new: Memory Builder)

Configurable memory training for songs, poems, sequences, speeches, or any ordered content.

Built-in Content:

  • Tom Lehrer's "The Elements" — periodic table set to music, with interactive element identification

Custom Content:

  • User adds any text/song/sequence they want to memorize
  • System breaks it into chunks and builds progressive recall exercises

Training Modes:

  • Learn — progressive reveal: show content line-by-line, then chunk-by-chunk, building from small to large
  • Fill-in-the-Blank — show partial content with blanks to fill; difficulty increases as more words are blanked
  • Sequence Recall — given a starting point, continue the sequence from memory
  • Random Prompt — given a random line/chunk, identify what comes before and after
  • Speed Run — recite the full sequence as fast as possible with accuracy tracking

Spaced Repetition:

  • Track per-chunk mastery (how often recalled correctly, average response time)
  • Focus training on weakest chunks
  • Graduated difficulty: new items start with heavy hints, mastered items tested with no hints

3. Wordplay (existing, enhanced)

  • Pun/Wordplay — create puns on given topics (LLM-scored)
  • Word Association — free-associate with prompt words (LLM-scored)

4. Verbal Agility (existing)

  • Wit Comeback — respond to scenarios with humor (LLM-scored)
  • Verbal Fluency — name items in a category within time limit (LLM-scored)
  • Story Recall — read a paragraph, answer detail questions (LLM-scored)

5. Imagination & Ideation (new)

Creative thinking exercises scored by AI for originality, elaboration, and feasibility.

  • What If — respond to absurd hypothetical scenarios ("What if gravity reversed for 10 minutes every Tuesday?")
  • Alternative Uses — list creative uses for a common object (divergent thinking classic)
  • Story Prompt — given 3 random words, create a micro-story connecting them
  • Invention Pitch — given a problem, pitch an inventive solution in 2-3 sentences
  • Reframe — take a negative situation and reframe it positively/humorously

Session Structure (~5 minutes)

A POST session pulls one drill from each enabled domain, time-budgeted:

Domain Drill Count Time Budget
Math 1 drill (e.g., 10 multiplication problems) ~60s
Memory 1 memory item exercise ~90s
Wordplay 1 drill (e.g., 3 pun challenges) ~60s
Verbal 1 drill (e.g., 1 story recall) ~60s
Imagination 1 drill (e.g., 2 what-if prompts) ~60s

Total: ~5.5 minutes with transitions. Users can enable/disable any domain.

Training vs Testing

Each domain supports two modes:

  • Train — learning-focused: hints, progressive difficulty, immediate feedback, no final score
  • Test — performance-focused: timed, scored, saved to session history

The session launcher lets users pick mode per-domain. Training sessions are tracked separately (practice count, streaks) but don't contribute to the scored POST history.

Elements Song Memory Builder

Content Structure

The Tom Lehrer "Elements Song" is stored as structured data:

  • Full lyrics split into lines
  • Each element name mapped to its atomic number and symbol
  • Musical phrases grouped for chunked learning

Interactive Features

  • Karaoke Mode — lyrics scroll with timing, user fills in blanked element names
  • Element Flash — show atomic number or symbol, user names the element (and vice versa)
  • Sequence Game — "What element comes after Arsenic in the song?"
  • Progress Map — periodic table colored by mastery (green = solid, yellow = shaky, red = unlearned)
  • Audio Reference — link to the song for listening practice (user provides their own audio file)

Data Model

{
  "memoryItems": [
    {
      "id": "elements-song",
      "title": "The Elements (Tom Lehrer)",
      "type": "song",
      "builtin": true,
      "content": {
        "lines": [
          { "text": "There's antimony, arsenic, aluminum, selenium", "elements": ["Sb", "As", "Al", "Se"] },
          { "text": "And hydrogen and oxygen and nitrogen and rhenium", "elements": ["H", "O", "N", "Re"] }
        ],
        "chunks": [
          { "id": "verse-1", "lineRange": [0, 3], "label": "Verse 1" }
        ]
      },
      "mastery": {
        "overallPct": 45,
        "chunks": { "verse-1": { "correct": 12, "attempts": 20, "lastPracticed": "2026-03-08" } },
        "elements": { "Sb": { "correct": 5, "attempts": 5 }, "As": { "correct": 3, "attempts": 5 } }
      }
    }
  ]
}

Custom Memory Items

Users can add their own items via the Config page:

{
  "id": "user-uuid",
  "title": "Gettysburg Address",
  "type": "speech",
  "builtin": false,
  "content": {
    "lines": [
      { "text": "Four score and seven years ago our fathers brought forth on this continent, a new nation" },
      { "text": "conceived in Liberty, and dedicated to the proposition that all men are created equal." }
    ],
    "chunks": [
      { "id": "opening", "lineRange": [0, 1], "label": "Opening" }
    ]
  },
  "mastery": {}
}

Scoring

  • Math: accuracy (80%) + speed bonus (20%), server-rescored
  • Memory: chunk accuracy (70%) + sequence accuracy (20%) + speed (10%)
  • Wordplay/Verbal/Imagination: LLM-scored on quality criteria (80%) + speed bonus (20%)
  • Session score: weighted average across all completed drills
