The second hypothesis was that a digital learning task characterized by both autonomy
support and structure would have a positive effect on intrinsic motivation. This hypothesis
was also supported by the results, though the occurrence of both dimensions was not
necessary for promoting intrinsic motivation. The results showed that even a single
dimension (autonomy support or structure) was sufficient to foster intrinsic motivation.
The positive interaction suggests, however, that when both autonomy support and structure
are present they are mutually supportive and result in high motivation. If both are absent,
however, low intrinsic motivation results. This finding concurs with previous research
suggesting that environments that inhibit the fulfillment of these needs yield fewer optimal
forms of motivation
