## Experimental Data (P1_YA_AO_UKCH_exp.csv)

ID: participant number

site: testing site (UK = United Kingdom, CH = Switzerland)

trial: trial number

condition: single- or dual-task condition identifier. ST = single-task, DT = dual-task, Mem = memory, Proc = processing

format: memory task condition (AO = audio presentation with oral response)

AS: articulatory suppression condition (1 = AS, 0 = no AS)

memSpan: memSpan: number of memory items presented (list length)

procSpan: number of processing items presented

memItems: presented memory items, separated by '-'

memResps: participant responses to memory task, separated by '-'

memNcorr: number of memory items correctly recalled

memRT: time taken to respond to all memory items (seconds)

procItems: augends and addends for the processing task separated by '-' (e.g. 72 represents the sum 7 + 2)

procAns: the presented solution to each processing item

procCorrIncorr: indicates whether the presented answer was correct (1) or incorrect (0)

procResps: participant responses to the processing task (i.e. whether they answered correct [1] or incorrect[0])

procNcorr: number of correct participant responses

procRT: reaction times for each processing item (ms), separated by '-'

fullID: full participant identifier



## Titration Data (P1_YA_AO_UKCH_titr.csv)

ID: participant number

site: testing site

titrating: task that is being titrated

pres_recall: memory task condition (AO = audio presentation with oral response). For processing titration, this decided the placeholder task

AS: articulatory suppression

stairLevel: the titration stair level. Default max is 8, unless that trial was the highest span achieved so far

levelTrial: trial number within a stair level (max 2)

nMemItems: number of memory items

memItems: presented memory items

memResps: memory responses

memNcorr: number of memory items correctly recalled

memRT: time taken to respond to all memory items

nProcItems: number of processing items presented

processingDigits: augends and addends for the processing task

processingSums: the presented solution to each processing item

processingCorrAns: indicates whether the presented answer was correct (1) or incorrect (0)

processingResps: participant responses to the processing task

procNcorr: number of correct participant responses

procRTs: reaction times for each processing item (ms)

fullID: full participant identifier


## Stimuli discrimination test data (P1_YA_VT_UKCH_preTest.csv)

ID: participant number

site: testing site

stimulus: presented letter

response: participant response

RT: reaction time (seconds)

fullID: full participant identifier
