Neurocognitive mechanisms of collaborative recall.

Research on collaborative memory shows that people recalling in groups rarely achieve optimal performance. Collaborative groups typically recall less than nominal groups, where performance for the latter is derived by pooling the non-overlapping information recalled by the same number of individuals working alone. While behavioural evidence has widely replicated this collaborative inhibition in free recall, little evidence speaks to the neurophysiological signatures of this counterintuitive phenomenon.

Persistence of false memories and emergence of collective false memory: collaborative recall of DRM word lists.

Information and misinformation are proliferating on social media. A rapid rise in the use of these platforms makes it important to identify psychological mechanisms that underlie the production, propagation, and convergence of false memories in groups. Websites and social media platforms vary in the extent of restrictions placed on interactive communication (e.

When social influences reduce false recognition memory: A case of categorically related information.

Social interactions create opportunities for reminiscence and memory rehearsal but can also lead to memory errors. We tested how the type of information people remember can influence the magnitude of memory errors they make following collaborative discussion. Past findings show that unrelated item lists and emotional salient items reduce false alarms and improve memory discrimination, respectively, on an individual recognition test after collaborative discussion compared to no prior collaboration.

Collaborative remembering of emotional autobiographical memories: Implications for emotion regulation and collective memory.

People frequently engage in conversation about shared autobiographical events from their lives, particularly those with emotional significance. The pervasiveness of this practice raises the question whether shared memory reconstruction has the power to influence the memory and emotions associated with such events. We developed a novel paradigm that combined the strengths of the methods from autobiographical and collaborative memory research traditions to examine such consequences.

Social Transmission of False Memory in Small Groups and Large Networks.

Sharing information and memories is a key feature of social interactions, making social contexts important for developing and transmitting accurate memories and also false memories. False memory transmission can have wide-ranging effects, including shaping personal memories of individuals as well as collective memories of a network of people. This paper reviews a collection of key findings and explanations in cognitive research on the transmission of false memories in small groups.

Happiness increases verbal and spatial working memory capacity where sadness does not: Emotion, working memory and executive control.

The effects of emotion on working memory and executive control are often studied in isolation. Positive mood enhances verbal and impairs spatial working memory, whereas negative mood enhances spatial and impairs verbal working memory. Moreover, positive mood enhances executive control, whereas negative mood has little influence.
