the block doesn't end when there are 2 correct responses on trial 'three' and 2 incorrect on trial 'four', for example.

Thank you for the quick reply. I set up the stop logic like this, but it still doesn't seem to be working:
<block test>
/trials = [1=one]
/stop = [
    (trial.one.totalerrorcount >=2);
    (trial.one.totalcorrectcount >=2 && trial.two.totalerrorcount >=2);
    (trial.two.totalcorrectcount >=2 && trial.three.totalerrorcount >=2);
    (trial.three.totalcorrectcount >=2 && trial.four.totalerrorcount >=2);
    (trial.four.totalcorrectcount >=2 && trial.five.totalerrorcount >=2);
    (trial.five.totalcorrectcount >=2 && trial.six.totalerrorcount >=2);
    (trial.six.totalcorrectcount >=2)]
</block>
in particular, it seems like the expressions with && are the ones not being properly evaluated. Any advice?

here's an example of one of the relevant trials:

<trial one>
/ stimulusframes = [1=one, plus_one, minus_one, try_again,
pond, duck_1_a, duck_1_b, duck_2_a, duck_2_b, duck_3_a, duck_3_b, duck_4_a, duck_4_b, duck_5_a, duck_5_b,
pond]
/ inputdevice = dragdrop
/ showmousecursor = true
/droptargets = (pond)
/ validresponse = (plus_one, minus_one, try_again)
/ correctresponse = (plus_one)
/ontrialbegin=[
    picture.duck_1_a.hposition=24%;
    picture.duck_1_a.vposition=45%;
    picture.duck_1_b.hposition=5%;
    picture.duck_1_b.vposition=30%;
    picture.duck_2_a.hposition=20%;
    picture.duck_2_a.vposition=30%;
    picture.duck_2_b.hposition=15%;
    picture.duck_2_b.vposition=40%;
    picture.duck_3_a.hposition=25%;
    picture.duck_3_a.vposition=55%;
    picture.duck_3_b.hposition=5%;
    picture.duck_3_b.vposition=20%;
    picture.duck_4_a.hposition=10%;
    picture.duck_4_a.vposition=35%;
    picture.duck_4_b.hposition=20%;
    picture.duck_4_b.vposition=35%;
    picture.duck_5_a.hposition=30%;
    picture.duck_5_a.vposition=55%;
    picture.duck_5_b.hposition=13%]
/branch = [if (trial.one.response == "try_again") trial.one]
/branch = [if (trial.one.response == "minus_one") trial.one]
/branch = [if (trial.one.response == "plus_one") trial.three]
</trial>

/branch attributes at the <block> level are executed when that block ends, not sometime in the middle of the block, while the block is still running trials. It's not clear at all from the snippets you posted when the block ends.

E.g. if you want the block to immediately terminate after two errors in <trial one>, you need to put some /stop logic in the <block> to do that etc.

> it seems like the expressions with && are the ones not being properly evaluated

What makes you think that, please?

I'm not sure what kind of description I should provide. It's meant to function as a counting task to be administered to children. They are asked to drag the ducks into a pond. There is a demonstration trial first, and then they are asked to place successive numbers of ducks into a pond (e.g., 1 duck, then 3 ducks, then 4, then 5). It's titrated, so if they get a number wrong, they go up a number. If they get it right, they go down a number. An adult grades their answers by either pressing "next' or "previous" (depending on whether the child got the answer right or wrong). The experiment is meant to end when children either a) fail the 1 trial twice, b) fail any given trial twice, but succeed on the previous trial twice, or c) succeed on the last trial twice.

Sorry, I meant to say - if they get a number wrong, they go down a number. If they get it right, they go up a number*
