The Avon Longitudinal Study of Parents and Children (ALSPAC) assessed their cohort members (CMs) during the study’s age 11 sweep (Focus 11+ Clinic) using a measure of Higher Conceptual Reasoning (Bike Drawing Task).
Details on this measure and the data collected from the CMs are outlined in the table below.
|Domain:||General ability (perceptual)|
|Measures:||Higher conceptual reasoning|
|CHC:||General ability (G)|
|Administration method:||Trained interviewer; clinical setting; pen and paper|
|Procedure:||The child was asked to draw a bicycle within a box on a piece of A4 paper. They were given a maximum of 3 minutes to complete the task, and were prompted with 30 seconds remaining. They were scored on whether any of 12 basic items necessary for a bike to function were present in the drawing (e.g. wheels, handlebars). A further 10 more detailed items were also scored (e.g. basket, bell), as were 3 possible background aspects of the picture (road, landscape, sky).|

|Scoring:||In the early stages, each criterion was scored present/absent. However, additional coding was required to note whether an item was functional (e.g. pedals attached to frame), and scoring was later amended to Yes, functional; Yes, not functional and No. There is a summary variable that indicates which coding scheme was used. According to the latest ALSPAC documentation, early data is currently being recoded to the new format.|
|Item-level variable(s):||febd001 - febd101|
|Total score/derived variable(s):||febd020a - febd071|
|N = 4,296|
|Range = 0 - 16|
|Mean = 6.08|
|SD = 2.70|

|Age of participants:||Mean (months) = 140.97, SD = 2.86, Range = 125 - 163|
|Other sweep and/or cohort:||None|
