Item Open Access A Telephone-Assisted Planning Intervention to Promote Parental Support for Physical Activity Among Children and Youth With Disabilities(2016-11-25) Tanna, Sunita; Basett-Gunter, RebeccaEnhanced parental support could increase physical activity (PA) among children and youth with disabilities (CYD). The multi-process action control (M-PAC) model highlights behavioral strategies such as action planning (AP) as critical in facilitating parental support. There is no known research examining AP as a tool to promote parental PA support among parents of CYD. Purpose: Evaluate a telephone-assisted AP intervention for promoting parental PA support. Method: Parents of CYD were randomized to a telephone-assisted AP intervention (n= 28) or no-support control group (n= 29). Results: Compared to the no-support control group, parents who received the telephone-assisted AP intervention were 80% more likely to action plan. A significant time x condition interaction was found for behavioural strategies (i.e., planning, monitoring) (F(1,36)= 4.14, p= .049). Conclusion: Parents in the telephone-assisted AP intervention increased behavioural strategies to support their childs PA, which suggests AP support may enhance AP and parent support for PA.Item Open Access Action Intention Modulates the Activity Pattern in Early Visual Areas(2018-08-27) Velji- Ibrahim, Jena; Crawford, John DouglasThe activity pattern in the early visual cortex (EVC) can be used to predict upcoming actions as it is functionally connected to higher-order motor areas. However, the mechanism by which the EVC enhances action-relevant features is unclear. We explored this using fMRI. Participants performed Align or Open Hand movements to two oriented objects. We localized the calcarine sulcus, corresponding to the periphery, and the occipital pole, corresponding to the fovea. During planning, univariate analysis did not reveal significant results so we used multi-voxel pattern analysis (MVPA) to decode action type and object orientation. Though objects were located in the periphery, we found a significant decoding accuracy for orientation in an action-dependent manner in the occipital pole and action network areas. We established the functional connectivity between the EVC and somatomotor areas during planning using psychophysiological interaction (PPI) analysis. Taken together, our results show object orientation is modulated by action preparation.
