- Misinformation in social interaction: Examining the role of discussionPublication . Saraiva, Magda; Garrido, M. V.Memory is a reconstructive process that is prone to intrusions and distortions. These processes can be amplified by the emergence and propagation of false information in the social environment. While the acceptance of misinformation is well documented in individual memory tasks, the production of false memories in social interaction contexts presents mixed findings. One factor that may contribute to these inconsistencies is the collaboration method used, which may vary in the opportunities they offer for more (free-for-all) or less (turn-taking) discussion. The current study contrasts these two collaboration methods in misinformation acceptance. Participants watched a video, followed by an individual recall task. Then, they completed a questionnaire containing true and misinformation about the video, individually or in pairs (using free-for-all or turn-taking methods). Finally, participants were given a new individual recall task. Results revealed that participants responding to the questionnaire using the free-for-all method were more accurate and accepted less misinformation (vs. turn-taking and individual conditions). Critically, in the second individual recall, these participants also recalled less misinformation from the questionnaire than those in the turn-taking condition. These results suggest that discussion opportunities during social interaction enhance correction and error-pruning and reduce misinformation acceptance.
- Nutritional profile and consumers’ perceptions of cereal barsPublication . Saraiva, Magda; Garrido, Margarida; Viegas, Cláudia; Prada, MaríliaThe fast pace of our daily lives often prompts consumers to seek convenient and ready-to-eat snacks, such as cereal bars. This work aims to characterize the cereal bars available in the Portuguese market (Study 1), as well as consumers’ perceptions of different types of these products (Study 2). First, we collected data (e.g. nutritional information, price) on 277 cereal bars from two major Portuguese retailers. The results indicated that most of these products do not comply with the current guidelines for key nutrients like sugar, fat, and salt. Second, using an online survey, we asked participants (N = 373) to evaluate cereal bars from different categories (e.g. “energy/protein”) across eleven dimensions. Overall, the bars were rated as tasty but also unhealthy, highly caloric, processed, and unsuitable for athletes, children, and weight loss. Interestingly, participants overestimated the content of most nutrients contained in cereal bars. A content analysis revealed that participants indicated more reasons for not consuming (e.g. excessive sugar content) than consuming (e.g. convenience) these products. Given the increasing popularity of cereal bars, our findings call for action from multiple stakeholders toward improving cereal bars’ nutritional profile and advancing our understanding of consumers’ perceptions of these products to facilitate healthier choices.
- Collaborative inhibition effect: The role of memory task and retrieval methodPublication . Saraiva, Magda; Albuquerque, Pedro B.; Garrido, Margarida V.It is well established that the recall of collaborative groups is lower than the pooled recall of an equal number of lone individuals—the collaborative inhibition efect (Weldon and Bellinger, J Exp Psychol Learn Memory Cogn 23(5):1160–1175, 1997). This is arguably the case because group members have conficting retrieval strategies that disrupt each other's recall—the retrieval strategies disruption hypothesis (Basden et al., J Exp Psychol Learn Memory Cogn 23(5):1176–1191, 1997). In two experiments, we further examined this hypothesis by testing whether the memory task (free recall vs. serial recall) and the recall method (turn-taking vs. unconstraint) moderate collaborative inhibition. Experiment 1 compared the performance of collaborative and nominal groups in a free recall and a serial recall task. Results revealed collaborative inhibition in free recall, but this efect was reduced in serial recall. In Experiment 2, collaborative and nominal performance was compared in the same tasks with collaborative but also nominal groups, using the turn-taking method. The collaborative inhibition efect was still observed in free recall, although to a lesser extent when participants in nominal groups used the turn-taking method. In the serial recall task, the collaborative inhibition efect was eliminated. Taken together, these results further support retrieval strategies disruption as an explanation for the collaborative inhibition efect.
- Does the linguistic expectancy bias extend to a second language?Publication . Garrido, Margarida V.; Saraiva, Magda; Semin, Gün R.The linguistic expectancy bias (LEB) reflects the tendency to describe expectancyconsistent behavior more abstractly than expectancy-inconsistent. The current studies replicate the LEB in Portuguese and examine it in a second language (English). Earlier studies found differences in processing a first language (L1) and a second language (L2) shaping affective and cognitive processes. We did not expect these differences to shape the LEB because controlled lexical decisions (e.g., use of verbs and adjectives) are unlikely, even when using L2. Participants wrote stereotypically male or female behavioral descriptions for male and female targets. A new group of participants read those descriptions and was asked about their causes. Expectancy-consistent behavior was described more abstractly and shaped more dispositional inferences in L1 and L2. Aside from replicating the LEB in a different language, these studies indicate that structural features of language preserve a linguistic bias with implications for social perception even when using a second language.
