Robots　are　increasingly　being　employed　in　educational　environments　to　enhance　learning　experiences.　Adolescents　may　interact　with　robots　differently　from　younger　children　due　to　cognitive　and　perceptual　maturation.　This　study　examines　the　influence　of　robot　ability,　task　complexity,　risk,　and　self-construal　on　adolescents’　confidence　and　trust　in　robots,　and　decision-making.　Six　participants　(aged　14–16)　collaborated　with　the　NAO　robot　in　a　length　judgment　task.　Results　showed　that　high-ability　robots　elicited　more　trust,　confidence,　and　decision　change.　In　complex　tasks,　trust　was　highest　with　low-ability　robots,　while　trust　was　lowest　in　simple　tasks.　Participants　were　less　inclined　to　share　benefits　but　expect　robots　to　bear　losses.　Interdependent　individuals　showed　more　decision　changes.　These　findings　increase　the　understanding　of　the　way　that　adolescents　collaborate　with　robots,　especially　in　decision-making　processes.　©　2024,　The　Author(s),　under　exclusive　license　to　Springer　Nature　Switzerland　AG.
