# typically we begin with a trial template: trial_template <- trial_html_button_response( stimulus = insert_variable(name = "my_stimulus"), choices = c("true", "false") ) # then we fill it out so that there is now a "block" of trials: equations <- c("13 + 23 = 36", "17 - 9 = 6", "125 / 5 = 25") trials <- build_timeline(trial_template) %>% set_variables(my_stimulus = equations) # we can randomise presentation order and repeat the block: trials <- trials %>% set_parameters(randomize_order = TRUE, repetitions = 2)
