“…In a further n = 19 studies, brain or behavioural data was collected once during a follow-up - months, years or decades later. Thirteen studies followed the longitudinal design and repeated the same measures of either brain ( Lee et al, 2019 ; Wang et al, 2019 ; Swingler et al, 2017 ; Bernier et al, 2016 ) or behaviour ( Broomell et al, 2019 ; Diaz et al, 2019 ; Pratt et al, 2019 ; Licata et al, 2015 ; Beckwith and Parmelee, 1986 ) or both ( Hardin et al, 2021 ; Eggebrecht et al, 2017 ; Jones et al, 1997 , 2004 ). Seven of these studies included a time point during which brain and behaviour data were available concurrently ( Hardin et al, 2021 ; Broomell et al, 2019 ; Diaz et al, 2019 ; Eggebrecht et al, 2017 ; Swingler et al, 2017 ; Bernier et al, 2016 ; Jones et al, 1997 , 2004 ).…”
