“…In a typical research paradigm of collaborative memory, participants first study a list of items separately and then take a recall test either individually or collaboratively. Research adopting this paradigm has confirmed that people working collaboratively remember more items than individuals working alone (Barnier et al, 2018;Harris et al, 2017;Nie et al, 2019Nie et al, , 2021Nie et al, , 2022. Such findings are in line with the commonsensical saying "strength in numbers. "…”

“…In the collaborative groups, participants are informed to retrieve collaboratively. The nominal group is equal in size to the collaborative group, and members are randomly assigned to retrieve individually (Bärthel et al, 2017;Browning et al, 2018;Maswood et al, 2019;Nie et al, 2019Nie et al, , 2021Nie et al, , 2022.…”

“…Taking a group of dyads as an example, if one participant recalls Items A, B, and C, and the other participant recalls Items A, D, and E, the pooled nonredundant items are A, B, C, D, and E. Comparisons between collaborative and nominal groups reveal that collaboration can both facilitate and inhibit memory. Regarding the quantity of correctly remembered items, collaborative groups perform worse than nominal groups, and this difference is termed collaborative inhibition, a detrimental effect (Barber et al, 2015;Bärthel et al, 2017;Browning et al, 2018;Nie et al, , 2022. On the contrary, the number of errors is significantly lower in collaborative versus nominal groups, and this beneficial effect is called error pruning (Bärthel et al, 2017;Browning et al, 2018;Nie et al, 2019Nie et al, , 2021Nie et al, , 2022Rossi-Arnaud et al, 2018).…”

Existing collaborative memory research has shown statistically significant detrimental and beneficial effects (i.e., collaborative inhibition, error pruning, and post-collaborative memory benefit). However, it remains unknown yet whether they are modulated by stimulus emotionality of adjacent stimuli and whether they would differ in distinct memory tasks (item memory vs. source memory). To address these issues, the current study adopted the emotional timeout procedure, where participants individually studied a series of triplets (a preceding neutral word, a modulator word of taboo, nontaboo negative, neutral, or positive emotionality, and a following neutral word) displayed in red or green, and three recall sessions and a surprise recognition test was conducted afterwards. Results revealed reliable beneficial effects of collaboration. (a) The error pruning was reliably observed within ongoing and lasting collaboration in item memory tasks while it faded away post-collaboration in source memory conditions. (b) The post-collaborative memory benefit was confirmed in all word positions. It occurred in taboo, neutral, and positive words for modulators of different emotionality, while that of the preceding and following neutral words were insensitive to the emotionality of the modulator. The effect was only present in item memory, offering compelling evidence for dual-process models. (c) Collaboration facilitated the picked-up effect and the formation of shared memory. However, the detrimental effect of collaborative inhibition was absent in both memory tasks. These findings demonstrated that the mechanisms of the retrieval strategy disruption hypothesis (RSDH) took effect under the emotional timeout procedure to a certain degree.

Collaborative recall by groups of people can evoke both memory detriments (e.g., collaborative inhibition) and benefits (e.g., error pruning and post-collaborative memory benefit). Yet, it remains indeterminate whether these effects are due to the emotional valence of stimuli and/or the specific subtypes of episodic memory tested (i.e., item memory and source memory), and whether they are related to the research procedure of directed forgetting (DF). We introduced item-method DF into collaborative memory research using a turn-taking procedure. The to-be-recalled words were studied in different emotional valences and were followed by either an R or F cue, which, respectively, instructed participants to remember or forget the words presented. We conducted two recall sessions (Recall 1 and Recall 2) that included the two subtypes of episodic memory. Recall 1 was performed either individually or collaboratively, while Recall 2 was always performed individually. We observed three major findings: (a) a collaborative memory decrement - collaborative inhibition - was minimally affected in both item memory and source memory tasks by either the emotional valence of the stimuli or the DF cue; (b) a collaborative memory benefit - error pruning of item memory - persisted within both ongoing and post-collaboration, while error pruning of source memory only presented in ongoing collaboration, thus demonstrating the relevance of dual-process models that differentiate automatic familiarity and effortful recollection processes; and (c) there was no post-collaborative memory benefit, indicating the importance of the type of collaborative procedure. We discuss these results in terms of various theories, including the retrieval strategy disruption hypothesis (RSDH) which asserts that memory strategies tend to be disrupted in collaboration but are facilitated within post-collaboration. Also, we describe the implications of these results and directions for exploring other influential factors in future research.
