Greta and Hattie participated in a memory experiment. For the learning phase, Greta needed to produce words from a cue (e.g., she was shown hot-c_____ and needed to produce the word "cold."). Hattie was simply shown the words (e.g., "cold") and had to passively read them. When both participants were asked to recall as many of the words as possible, it was found that Greta's performance was significantly better. This outcome is most likely attributable to:   1. The Generation effect   2. Recognition enhancement    3. Emotion enhancement   4. Encoding specificity
