Child as a Mathematician

Question 1

(brief) What was the study of Van Herwegen (2008) about?

Answer 1

Assessing number processing abilities in TD and WS infants and toddlers

Question 2

When was the Van Herwegen study from?

Answer 2

2008

Question 3

What system is argued for in Van Herwegen (2008)

Answer 3

The papers argues for two representational systems, together making up number sense:

1. Object-based /object-file system (small numerosities ie 2 and 3)
2. Number estimation system (larger numerosities ie 8 and 16)

Question 4

What is the difference between habituation and familiarization?

Answer 4

Habituation: a stimulus is shown until reaction / engagement drops below a set threshold

Familiarization: A stimulus is shown a fixed amount of times

Question 5

What task did young TD infants struggle more with: Small numerosities or larger numerosities?

Answer 5

TD children struggle more with small numerosities (when variables such as density and area is controlled for) - and succeed with larger numerosities (depending on ratio - Webers Law - , ie success: 16 vs 32, but not 16 vs 24)

Question 6

What type task did WS children struggle more with:
Small numerosities or larger numerosities?

Answer 6

WS children struggle more with larger numerosities

Question 7

Is webers law modal or amodal?

Answer 7

Amodal - the same principle (experienced intensity of stimuli depends on the intensity of intial stimuli) occurs across modalities (ie across the senses; visually, auditory etc.)

Question 9

What is order indifference?

Answer 9

Order indifference refers to the understanding that, when counting, it does not matter which item you start with

A step in learning counting

Question 10

What is one-to-one correspondence

Answer 10

One-to-one corresponding refers to assigning each object with a label (a number)

A step (constraint) in learning counting

Question 11

What is item indifference
