    Attention & Memory Entry #0181

    The reason the first and last items survive the list

    Recall of a list is reliably U-shaped. The ends are protected by two different mechanisms, and the middle is protected by neither.

    Adept
    The hidden part #0181

    Two mechanisms guard two ends. Primacy survives a delay and recency does not, which is how they are told apart.

    Why testing yourself beats rereading

    Rereading feels like learning and mostly is not. The method that feels least productive is the one that leaves the most behind.

    Adept
    The hidden part #0196

    Fluency is a sensation, not a measurement. The method that feels like it is failing is frequently the one doing the work.

    Why reading on paper is remembered differently to screen

    Readers on paper locate a passage by where it sat on the page. Readers on screen scroll and the spatial anchor disappears.

    Novice
    The hidden part #0186

    Paper gives a passage a place. A screen gives it a position in a stream, which moves on.

    Why background music helps one task and ruins another

    Music with lyrics impairs reading and leaves arithmetic untouched. The damage is channel-specific, not a general drain on attention.

    Adept
    The hidden part #0184

    Music competes only with tasks that use the same channel. Lyrics fight language; a beat does not.

    The reason a familiar route feels shorter going home

    The outward journey takes longer than the return, though the distance is the same. What changed is what the traveller expected.

    Adept
    The hidden part #0183

    The road did not change. The forecast did. Duration is the gap between what happened and what was expected.

    Why sleep decides what yesterday meant

    A day deposits more than it can store. Sleep selects which portions are kept and which are discarded, and the selection is not random.

    Novice
    The hidden part #0182

    Sleep is not a gap in processing. It is when the day is edited into what will count as having happened.

    Why a moving object is remembered worse than a still one

    Tracking a moving target consumes the same capacity that encoding it into memory requires. The object is seen clearly throughout and recalled poorly afterwards.

    Master
    The hidden part #0180

    Position and identity are maintained by competing budgets. Tracking preserves where at the cost of what.

    The reason you cannot read and listen at the same time

    Music and reading coexist comfortably. Speech and reading do not, because both compete for the same narrow language channel rather than for general attention.

    Adept
    The hidden part #0179

    Interference is channel-specific. Reading and speech collide because both are recoded through the same verbal loop.

    Why the room goes quiet when someone says your name

    You can ignore a conversation completely and still catch your own name inside it. The filter that discarded the rest was checking for it all along.

    Novice
    The hidden part #0178

    Unattended input is screened, not discarded. Personal salience is one of the few keys that opens the filter.

    The reason a interrupted task stays in memory longer

    Finish a task and your mind files it away. Leave it half-done and it keeps running in the background, consuming attention you thought you had freed.

    Adept
    The hidden part #0177

    Open loops keep their own reminder. The unfinished task does not wait quietly; it sends itself to the front of the queue again and again.

    Why you stop seeing the banner you looked at yesterday

    The advertisement has not moved and neither have your eyes. What changed is that your brain has decided it is scenery.

    Novice
    The hidden part #0176

    Repetition trains the eye to skip. The banner that is always there becomes the one thing that is never seen.
