I think that's why they're not attributing patients' performance to anhedonia. They're saying, it's not that patients aren't reward-driven, it's that they're driven to avoid effort.

Agree with everything you said. Healthy volunteers have only rewards. Patients have both rewards and penalties to consider. Even if you argue that healthy volunteers could have non-dominant arm/hand pain/stiffness the next day if they do lots of hard tasks, they also have the experience of...

I hear you. I'm in the same range as you. But to be honest it would be my cognition, sensitivities to noise/movement and orthostatic intolerance that would stop me participating, rather than anything the SF36PF would pick up. Imagine all the talking involved in this study? All the things...

The relevant modifications made - reducing the number of button presses required for the hard task from 100 to 98 and reducing the time from 20 mins to 15 mins - were clearly not enough to make the hard task doable for pwME. I haven't read enough of the other studies to know if those...

Yeah, and I think Treadway would agree with you given that following discussions with him, Reddy et al. modified the EEfRT in their schizophrenia study to have everyone do 50 trials. But since Walitt & co include them all, I did too. I wonder if they considered the modifications others have...

Full game, no practice rounds. They're looking at every choice between hard and easy, so it has to be the full game.

So my explanation for why there's no further reduction of proportion of hard tasks chosen below 90% successful completion would be that the rewards of money, and perhaps approval (of testers) and knowledge that you did what you were supposed to do are stronger factors in people's choices.

I see it as data-driven. Alternatively, you could say =100% vs <100, and the percentages would be 45% and 35%, and check that. I suggested above and below 90% because it seemed more reasonable clinically to allow healthy volunteers to not be perfect (but still not lose much confidence, thus...

Agree wholeheartedly with these points. Most days I can only skim so I will miss plenty of great content, unfortunately! Yes, the Ohmann paper has helpful bits like: The Reddy paper - the first I've been able to look at - is nice in that they have laid out exactly how the EEfRT could have...

Am so grateful for all the work you've done to make these more accessible! I'm baffled by most things so far today (the odd thing gets in clearly). Not a hope of me finding hex references. I think you've done more than enough already and could save your energy for analysis. Thank you so...

Well, wow. Thank you for running that. And, what is a GEE? I think we can work with that.

Worth noting how "Matters Arising" works in Nature Communications. You write your piece, then you submit it to the authors of the paper. You resolve what you can with them, and then, if you still think it necessary, you submit it to Nature Comms as "Matters Arising". So it gets sent to the...

To successfully complete this mission, any response will need to address their argument. It’s not that they didn’t notice what we’re noticing – that pwME successfully completed hard tasks less than HVs – they noticed it: I’m not sure the bit after “but” makes sense – I think they mean that...

Agree. As Simon M said, they're "a bunch of triers":

I was thinking about this yesterday. Looking at the entire sample of healthy volunteers and patients, people with success rates on hard tasks of above 90% chose hard tasks 44% of the time. People with success rates on hard tasks below 90% chose hard tasks 33% of the time. There is no...

Oooh I thought it was the mean successfully completed. But I also found myself wondering how the means and medians would differ.

I think having a contrast between the practice and real rounds is good. I still need to look at the graph on low brightness to be able for it, to make everything paler/more muted. If the rose were paler and the background cells were paler, it would be easier. Thank you so much for all the...

These are great – the mean lines (which Simon M wisely suggested for Karen Kirke’s graph) are so helpful for seeing what is going on. And I agree that the practice rounds contain important info. Can I suggest some tweaks? · Add a legend for the dotted lines. · Instead of True vs...

Aw listen, I know. It took me a while to figure out. Little things make so much difference, like black and ecru is much easier to look at than black and white. I find shades labelled "dusty" are brilliant, like dusty blue, dusty pink, dusty green - muted and calm. In graphs I like the "More...

So much better! If you can tone down the red I'll be able to feast my eyes on it!
