Prospective Estimation Task in ASC

Sample Task Main conclusions Commentaries
ASC NT
Szelag et al. [2004] n 7 7 Time reproduction ASC group performed worse in the time reproduction task

Small sample

Different IQ test in each group

Trend to differences in IQ

Age 12.6 Matched
IQ 82–102 95–145
Gowen and Miall [2005] n 12 12 Continuation and synchronization tapping

No differences in Coef. of variation

ASC group showed greater absolute error and greater stimulus asynchrony on synchronization task

Small sample
Age 24.2 24.2
IQ 114 114
Wallace and Happe [2008] n 25 25 Verbal estimation, production, and reproduction No differences in time reproduction, time production, and time estimation Recruitment of savants and a modification in the experimental paradigm could have been a factor affecting the results
Age 14.1 13.84
IQ 96.36 100.08
Martin et al. [2010] n 20 20 Time reproduction ASD group worse on measures of; absolute difference, mean judgment ratio, and mean coefficient of variation No control of chronometric counting
Age 35 35
IQ 106 108
Maister and Plaisted‐Grant [2011] n 21 21 Time reproduction

Differences in short (0.5 sec) and long durations (45 sec)

Short‐term memory was correlated with the error scores in short durations between 1 and 10 sec

No data about over or underestimation

Trend to differences in IQ

Age 11.3 10.7
IQ 105.6 115.8
Brenner et al. [2015] n 27 25 Time reproduction

Poorer accuracy and consistency in ASC group

Accuracy was found associated with age and consistency with working memory

Age 12.68 13.41
IQ 101.31 106.96
Karaminis et al. [2016] n n = 23 n = 78 Time reproduction and discrimination

ASC group performed similar to younger children (6–7 years old)

Less use of priors in ASC

ASC children less accurate, but equally precise (consistent) in time reproduction task

Child friendly paradigm. The authors suggest using the traditional paradigms in order to avoid this possible interference
age Age: 12 (6–32 years old)
IQ IQ: 100.03
Sperduti et al. [2014] n 15 17 Verbal estimation Comparable reproduction error between groups Small sample
Age 33.53 33.06
IQ 109.38 105
