Built with Task Builder 1
Participants are shown the same 120 questions they encounter in the willingness-to-wait task and are asked to rate their curiosity upon first seeing each question. They respond on a scale from 1 (Not at all curious) to 7 (Very curious). The questions are randomly ordered.

This sentence verification test aims to objectively assess participants’ reading comprehension ability (reading fluency and decoding). It comprises 80 sentences. Participants are given 90 seconds in total to read and verify the truthfulness of these sentences, based on their real-world knowledge (for instance, “All birds are blue”). Each sentence only stays on screen for 3 seconds. Participants receive 1 point for each sentence they correctly verify, with a maximum possible score of 80.
To construct sentences for the sentence verification task, we developed a pool of key words. These words were drawn from the MRC Psycholinguistic Database, based on several characteristics: age of acquisition, concreteness, familiarity, imageability and written frequency. These key words were assigned to one of five blocks, with later blocks containing more challenging words. Sixteen sentences were generated per block. Each sentence contained a maximum of 2 key words, and words were not repeated. Sentence length also increased across the five blocks. Consequently, over the course of the task, we expected the sentences to become more difficult to read.

In this task, participants are presented with the 120 trivia questions. Visual and verbal questions are interleaved in blocks of 8 (4 visual/ 4 verbal), to ensure that participants do not see one type of stimuli excessively at any point in the experiment. Within each block, the presentation of items is random. Participants have a maximum of 10 seconds to read the question and choose their response. They are provided with three response choices, Skip, Wait and Know. If they already know the answer, they are instructed to press the Know key. They are instructed to press Skip if they do not know the answer and are not interested in finding out the answer, or aren’t willing to wait the amount of time designated by the Wait option. After a brief period, both the Skip and Know responses are followed by the next question. Participants are instructed to press the Wait button if they do not know the answer, are interested in finding out, and willing to wait the amount of time designated. The time delays associated with the Wait option vary, in 5-s increments, from 10 to 30 s (the time delay associated with each item is counterbalanced across participants). Upon choosing the “Wait” option, participants see a fixation cross for the duration of the wait time, and then the answer appears. Once participants choose to wait, they cannot change their choice. Participants are then asked to rate their satisfaction with the answer, on a scale from 1 (Not satisfied at all) to 7 (Very Satisfied).
