“…Among these are retrieval conditions where the retrieval task precludes retrieval disruption, as in the case of a recognition task in which all studied items are presented (Clark, Abbe, & Larson, 2006;Clark, Hori, Putnam, & Martin, 2000;Meade & Roediger, 2009) and in the case of a cued recall task in which the retrieval order is preset by the presentation order of the recall cues (Barber, Rajaram, & Aron, 2010;Finlay et al, 2000) and, therefore, retrieval disruption occurs to the same extent for both collaborative and nominal groups. Similarly, collaborative inhibition is also eliminated when participants are prevented from switching categories by requiring them to recall items from a given category contiguously before moving on to recalling items from another category (Basden et al, 1997, Experiment 4), once again aligning the same retrieval strategy for all participants.…”

Two experiments tested the effects of encoding manipulations on group recall and on the magnitude of collaborative inhibition. Collaborative inhibition refers to the phenomenon where by a collaborative group recalls less than do the same number of individuals who work alone and then have their nonredundant responses pooled. Participants studied categorized word lists once or three times (Experiment 1) or under conditions of full versus divided attention (Experiment 2). Study repetition both improved retrieval organization in recall and attenuated collaborative inhibition, and divided attention encoding both reduced retrieval organization in recall and eliminated collaborative inhibition. These experiments are the first to focus on encoding variables and to show that collaborative inhibition can vary as a function of encoding manipulations.

“…In contrast with Andersson and Rönn-berg (1995), Finlay, Hitch, and Meudell (2000) found that participants who engaged in a shared incidental encoding where they jointly searched for target animals in pictures subsequently showed no collaborative inhibition. Finally, Barber, Rajaram, and Aron (2010) found that individuals who engaged in a collaborative encoding task, where they took turns to generate sentences containing target words, subsequently performed more poorly on an individual recall test. However, they did not examine the outcomes in terms of the costs and benefits for collaborative recall.…”

We often remember in the company of others. In particular, we routinely collaborate with friends, family, or colleagues to remember shared experiences. But surprisingly, in the experimental collaborative recall paradigm, collaborative groups remember less than their potential, an effect termed collaborative inhibition. Rajaram and Pereira-Pasarin (2010) argued that the effects of collaboration on recall are determined by "pre-collaborative" factors. We studied the role of 2 pre-collaborative factors-shared encoding and group relationship-in determining the costs and benefits of collaborative recall. In Experiment 1, we compared groups of strangers who encoded alone versus together, before collaborating to recall. In Experiment 2, we compared groups of friends who encoded alone versus together, before collaborating to recall. We found that shared encoding abolished collaborative inhibition in both Experiments 1 and 2. But prior relationship did not influence collaborative inhibition over and above the effects of shared encoding. Regardless of encoding condition, collaborative group recall contained fewer intrusions than nominal group recall, and these benefits continued in subsequent individual recall. Our findings demonstrate that pre-collaborative factors-specifically shared encoding-have flow-on benefits for group and individual recall amount, but not recall accuracy. We discuss these findings in terms of self-and cross-cuing in collaborative recall.

“…Mario lo había visitado años antes en su primera visita a París mientras que Liliana lo visitó por primera vez en sus últimas vacaciones con Mario). En consecuencia, la información que Liliana y Mario recuerdan acerca de su visita al Centro George-Pompidou de forma colaborativa puede ser el resultado de haber codificado una misma o similar experiencia de forma compartida o separada (Barber, Rajaram, & Aron, 2010;Barnier, Sutton, Harris, & Wilson, 2008;Harris, Barnier, & Sutton, 2013;Pereira-Pasarin & Rajaram, 2011). Por supuesto que nuestras memorias individuales y colaborativas no siempre representan de forma acertada los acontecimientos que ocurrieron en el pasado, más bien funcionan como representaciones individuales y compartidas de ese pasado (Sutton, 2008).…”
