Results

The results of this study showed that the extent of sequencing in learning and progressive training advantages cannot be completely explained by direct associations between stimulus features and the equivalent responses. These findings were shown to be consistent with the idea of perceptual learning but not with a focus on stimulus variability.

Discussion

The results of this study support the idea that easy-to-hard sequencing presents an advantage in learning. When looking at all the sequencing types, progressive sequencing was shown to have the highest discrimination of the contrasts. It was also shown to have the best generalization to new contrasts even when participants are not trained to discriminate rate. Even though the study showed that participants experienced the exact same stimuli with matching stimulus variability and equal probabilities of having the last...

This shows that the advantage of progressive training comes from increased stimulus variability and not from other factors.
Critique

Overall this study was well done and the researchers did a good job at answering the question that they set out to. The experimental design that they used was clearly identified and laid out so that it could easily be understood. The one thing that was lacking in this study though was the identification of any limitations that were associated with it. At the end the authors did make recommendations for further research that could be done to enhance the findings that were presented in this study. This study was very easy to follow and understand which made it useful in increasing ones knowledge about the subject at hand.
