Explanation:

As you might expect, in both the individual and published results, positive word pairings had the highest pleasantness rating, while the lowest pleasantness ratings were given to the negative word pairings, with the remaining word type falling between these two extremes, in terms of perceived pleasantness of associated syllables.

No context is provided however this should be the right answer. Positive word pairings elicit a happier feeling in humans so they will have a higher pleasantness rating. Words such as money and happy for instance have very high pleasantness ratings.

Negative word pairings on the other hand will have the lowest pleasantness ratings as they have more sombre connotations.
