Yuka Machino @ymacci.bsky.social · 20/07/2026Dyads receiving selfish advice tended to choose asymmetric payoff patterns more than dyads receiving cooperative advice! So the content of advice only changed their coordination behavior when they knew it was in common ground. 100
Yuka Machino @ymacci.bsky.social · 20/07/2026Over time, participant dyads converged on stable coordination strategies. But some strategies were more fair than others: Dyads parking in A and B (stable orange) received the same bonus, but dyads parking in C and D (stable purple) received asymmetric bonuses. 100
Yuka Machino @ymacci.bsky.social · 20/07/2026Before the game, participants received advice in a 2×2 design manipulating the content of the advice (selfishly maximizing your own score vs. cooperatively favoring the partner) and whether it is in common ground (whether they were told their partner received the same advice or not). 100
Yuka Machino @ymacci.bsky.social · 20/07/2026We investigated how common ground about advice affects coordination by asking pairs of participants to play the 13-round car parking game from Dhara Yu & @wdt.bsky.social. They receive a bonus if they park in the same color, but score 0 if they choose the same spot. 100
Yuka Machino @ymacci.bsky.social · 20/07/2026Telling two people to be selfish barely changes their behavior, unless they both know they got the same message! Our #CogSci2026 paper reveals that these group expectations only matter when we all know that we share the same expectations. 1194
Yuka Machino @ymacci.bsky.social · 06/07/2025On the first point, our results are consistent with the observation that Americans typically interpret "quite" more as an amplifier (quite good = ⬆️ good), while British speakers often read it as a downtoner (quite good = 🤷 moderately good). 460
Yuka Machino @ymacci.bsky.social · 06/07/2025We conducted three experiments examining how people interpret various modified statements like "I'm very concerned" across a range of scenarios. The series of experiments aimed to distinguish social factors (e.g. politeness) from semantic factors (e.g. modifying the strength of the statement). 140
Yuka Machino @ymacci.bsky.social · 06/07/2025🎤 "Your #CogSci presentation was quite good this year." How flattered or offended will you be? The answer may depend on whether you speak British or American English 🇺🇸🇬🇧. Our new #CogSci2025 paper reveals systematic differences in how different cultures interpret the same words. 47316
