Forgetting the Fear Through Suppression of Emotional Associations
MixedTopicTalk-03
Presented by: Dipti Singh
Associations play a vital role in encoding, storing and retrieving memories. Moreover, they contribute to the retention of traumatic memories, as these memories are often linked to specific events or places. When such associations become intrusive and out of proportion, they result in the development of psychological disorders. One way of intentionally disregarding these memories is through Directed Forgetting (DF). Previous DF-based research targeted item-based or declarative memory, leaving the associative memory area unexplored. The current research explores the role of intentional forgetting in associative memory with an auditory fear conditioning paradigm. 39 participants took part in the experiment. The acquisition phase involves 24 images, half of which were followed by a forget cue. Each image was presented for 8seconds and paired either with an aversive sound(CS+) or with no sound(CS-). The testing phase involves recall, recognition and liking rating. Additionally, 8-channel EEG recordings were taken throughout the experiment. 2x2 repeated ANOVA showed significant effects of instructions F(1,38)=146.26,p<.001,η²=.794. In associative recall both stimulus, F(1,38)=6.26,p=.017,η² =.14 and instructions, F(1,38)=25.53,p < .001,η²=.38 had a significant effect. Recognition and liking failed to reach significance. ERP results showed a significant effect of Instructions on LPP(F(1,27)= 6.06, p=.02) and N2(F(1,27)=4.83, p=.03) at Fp2, and a stimulus effect on N2 at F3(F(1,27)=5.96,p=.021). At Cz, paired t-tests revealed significant differences between the Forget and no-cue conditions for N2(t(27)= -2.07,p= .04,d=- 0.39) and P3(t(27) = -2.15,p =.04, d=- 0.41). The results may also have therapeutic implications for individuals struggling with traumatic memories.
