Manual counting of dots was performed on a double-blind manner in indicated number of animals and cells (see figure legends).
Of course, we can count on Dot to voice her suspicions - "I don't know what the world is coming to anymore, what with boys dressing up as girls and girls becoming boys!
Surprisingly, despite the degraded counting thresholds in the older observers, their ability to count the number of dots was, on average, quite accurate (i.e. veridical - Fig. 3A).
For example, on one item, children are asked to count two arrays of dots.
To make a decision, an optimal observer could simply count the number of dots that move in each direction and choose the direction with the most dots.
Dots and letters (adapted from the Addenbrooke's Cognitive Examination III;[ 42] ): The participant is asked to count four sets of dots without pointing to them and identify four partially drawn letters.
The dot enumeration task, which assesses the capacity to represent exact numerosities, requires the child to count the number of dots (ranging from 1 to 9) arrayed randomly in a box on half of the screen and determine whether the amount matches the Arabic numeral (1 to 9) presented on the other half of the screen.
Count the number of dots in that one marked square, then multiply the number of dots by the surface area.
At the age 10 clinic (median age: 10 years and 7 months, IQR: 10 years and 5 months–10 and years and 9 months) working memory was assessed using the Counting Span working memory task (Case et al., 1982) which involved counting and recalling numbers of dots on a screen.
This test involved counting and recalling numbers of dots on screens, which were administered in sets of two, three, four, and five screens.
The presence of spatiotemporal integration deficit across saccades was assessed by a possible disorganization of ocular exploration during visual search or sequential counting with unlimited presentation of dots (revisiting behavior) that induced inefficient search and overestimations of the number of dots.
