Lin H, Xiang J, Li S, Liang J, Jin H - Front Hum Neurosci (2015)

Bottom Line: Anticipation of emotional pictures has been found to be relevant to the encoding of the pictures as well as their later recognition performance.To address this issue, participants in the present study were asked to view emotional (negative or neutral) pictures.The present findings suggest that anticipation of negative pictures may enhance neural activity in their later recognition.

ABSTRACT
Anticipation of emotional pictures has been found to be relevant to the encoding of the pictures as well as their later recognition performance. However, it is as yet unknown whether anticipation modulates neural activity in the later recognition of emotional pictures. To address this issue, participants in the present study were asked to view emotional (negative or neutral) pictures. The picture was preceded by a cue which indicated the emotional content of the picture in half of the trials (the anticipated condition) and without any cues in the other half (the unanticipated condition). Subsequently, participants had to perform an unexpected old/new recognition task in which old and novel pictures were presented without any preceding cues. Electroencephalography data was recorded during the recognition phase. Event-related potential results showed that for negative pictures, P2 and P3 amplitudes were larger in the anticipated as compared to the unanticipated condition; whereas this anticipation effect was not shown for neutral pictures. The present findings suggest that anticipation of negative pictures may enhance neural activity in their later recognition.

Figure 5: Topographical maps based on mean amplitudes of P2 (180–230 ms) and P3 (330–400 ms) for all experimental conditions.

Mentions: The analysis on P2 amplitudes revealed a three-way interaction [F(1,19) = 6.51, p = 0.020, = 0.26]. For neutral pictures, neither main effects of anticipation and hemisphere nor their interaction was significant (ps > 0.10). For negative pictures, while main effects of anticipation and hemisphere was not significant (ps > 0.10), there was a significant interaction between these two factors [F(1,19) = 7.65, p = 0.012, = 0.29]. The amplitudes were larger for anticipated (3.79 ± 1.12 μV) as compared to unanticipated negative pictures (2.82 ± 1.11 μV) over the right hemisphere [F(1,19) = 6.08, p = 0.023, = 0.24], but the P2 amplitudes were similar in these two conditions over the left hemisphere (ps > 0.10). Other main effects or interactions did not reach statistical significance (ps > 0.10; Figures 3 and 5).
