Intervention(s)
The intervention consists of two orthogonal treatment manipulations embedded in a 24-
month simulated personal loan repayment task administered online via Prolific:
(1) Framing manipulation: The financial information shown to participants each month
(income, expenses, loan balance, interest, and running totals) is presented using either
gain-framed language (emphasizing what participants retain, save, or gain) or lossframed
language (emphasizing what participants owe, lose, or fall short of). The
underlying numerical values are identical across both framing conditions — only the
presentation differs.
(2) Feedback visibility manipulation: After each monthly decision, participants either see
(displayed condition) or do not see (hidden condition) their running composite
performance score.
Each participant is randomly assigned to exactly one combination of these two
manipulations (four arms: gain/displayed, gain/hidden, loss/displayed, loss/hidden) and
remains in that condition for the entire 24-month task.
