Item Examining the time course of post collaborative benefits across word lists and prose passages(Springer Science and Business Media LLC, 2024-07) Wei, Yunfeng; Charbonneau, Brooke Z.; Meade, Michelle L.; Hutchison, Keith A.In the current study, we investigated how long the effects of one single collaboration session continue to influence individual memory. Participants learned categorized word lists and prose passages individually, and then they were instructed to recall learned materials either collaboratively or individually. Following initial recall, participants completed an individual recall test after a delay of 5 min, 48 h, or 1 week. On the initial recall test, we found that collaboration reduced recall of correct items on both word lists and prose passages (collaborative inhibition), and that collaboration reduced false recall on both word lists and prose passages (error correction). However, on the subsequent individual memory test after a delay, the pattern of post collaborative effects differed across veridical and false recall. For both word lists and prose passages, post collaborative benefits on correct recall lasted 1 week. However, there were no lasting effects of error correction on subsequent false recall. These results suggest that the time course of post collaborative benefits can be long lasting, but they are selective to veridical recall. The results are explained by theories of reexposure and error correction.Item Does collaboration help or hurt recall? The answer depends on working memory capacity.(American Psychological Association, 2022-08) Hood, Audrey V. B.; Whillock, Summer R.; Meade, Michelle L.; Hutchison, Keith A.Collaborative inhibition (reduced recall in collaborative versus nominal, or individual, groups) is a robust phenomenon. However, it is possible that not everyone is as susceptible to collaborative inhibition, such as those higher in working memory capacity (WMC). In the current study, we examined the relationship between WMC and collaborative inhibition. Participants completed three shortened span tasks (AOSPAN, RSPAN, SSPAN). They then viewed categorized word lists individually and then recalled the word lists alone or with a partner (Test 1), followed by an individual recall (Test 2). For correct recall, collaborative inhibition was greater among lower WMC individuals and they showed no post collaborative benefits. Only higher WMC individuals benefited from prior collaboration. For false recall, higher WMC individuals had less false recall on Test 1 and 2 and collaboration reduced errors on Test 1 for both lower and higher WMC individuals. There were no lasting effects of collaboration on Test 2 errors. Furthermore, partner WMC appeared to influence recall, although this tentative finding is based on a smaller sample size. Specifically, on Test 2, participants had less false recall when their partner was higher in WMC and greater correct recall when both they and their partner were higher in WMC. We conclude that collaboration is relatively more harmful for lower WMC individuals and more beneficial for higher WMC individuals. These results inform theories of collaborative inhibition by identifying attentional control and working memory capacity as mechanisms that moderate the magnitude of the effect.Item How do associative and phonemic overlap interact to boost illusory recollection?(2018-10) Hutchison, Keith A.; Meade, Michelle L.; Williams, Nikolas S.; Manley, Krista D.; McNabb, Jaimie C.This project investigated the underlying mechanisms that boost false remember responses when participants receive study words that are both semantically and phonologically similar to a critical lure. Participants completed a memory task in which they were presented with a list of words all associated with a critical lure. Included within the list of semantic associates was a target that was either semantically associated (e.g., yawn) to the critical lure (e.g., sleep) or shared the initial (e.g., slam) or final (e.g., beep) phoneme(s) with the critical lure. After hearing the list, participants recalled each list item and indicated whether they just knew it was on the list or if they instead recollected specific contextual details of that item\'s presentation. We found that inserting an initial phonemic overlap target boosted experiences of recollection, but only when semantically related associates were presented beforehand. The results are consistent with models of spoken word recognition and show that established semantic context plus initial phonemic overlap play important roles in boosting false recollection.
