“…We further hypothesized that both TBI groups would demonstrate a decline in warm responsiveness over time and, conversely, an increase in negativity over time relative to an age-matched cohort of children with OI, again with the expectation of more pronounced differences following a severe TBI. Research involving parent–child interactions has demonstrated that the parent–child relationship experiences more stress in a structured as opposed to a nonstructured task (Healey, Gopin, Grossman, Campbell, & Halperin, 2010; Wade et al, 2008; Barkley, Karlsson, & Pollard, 1985). Hence, we also anticipated that maternal warm responsiveness would be lower in the teaching task.…”
