Greater traditionalism predicts COVID-19 precautionary behaviors across 27 societies.

People vary both in their embrace of their society's traditions, and in their perception of hazards as salient and necessitating a response. Over evolutionary time, traditions have offered avenues for addressing hazards, plausibly resulting in linkages between orientations toward tradition and orientations toward danger. Emerging research documents connections between traditionalism and threat responsivity, including pathogen-avoidance motivations. Additionally, because hazard-mitigating behaviors can conflict with competing priorities, associations between traditionalism and pathogen avoidance may hinge on contextually contingent tradeoffs. The COVID-19 pandemic provides a real-world test of the posited relationship between traditionalism and hazard avoidance. Across 27 societies (N = 7844), we find that, in a majority of countries, individuals' endorsement of tradition positively correlates with their adherence to costly COVID-19-avoidance behaviors; accounting for some of the conflicts that arise between public health precautions and other objectives further strengthens this evidence that traditionalism is associated with greater attention to hazards.

Can we learn from errors? Retrieval facilitates the correction of false memories for pragmatic inferences.

Errorful learning suggests that, when perfect learning has not yet been attained, errors can enhance future learning if followed by corrective feedback. Research on memory updating has shown that after retrieval, memory becomes more malleable and prone to change. Thus, retrieval of a wrong answer might provide a good context for the incorporation of feedback. Here, we tested this hypothesis using sentences including pragmatic sentence implications, commonly used for the study of false memories. Across two experiments with young adults, we hypothesized that corrective feedback would be more efficient at reducing false memories if provided immediately after retrieval, when memory is more malleable than after being exposed to the material. Participants' memory was assessed as a function of the type of learning task (Experiment 1: retrieval vs. restudy; and Experiment 2: active vs. passive recognition); and whether participants received corrective feedback or not. In both experiments, we observed that retrieval not only improved correct recall (replicating the testing effect) but also promoted the correction of false memories. Notably, corrective feedback was more effective when given after errors that were committed during retrieval rather than after restudy (Experiment 1) or after passive recognition (Experiment 2). Our results suggest that the benefits of retrieval go beyond the testing effect since it also facilitates false memories correction. Retrieval seems to enhance memory malleability, thus improving the incorporation of feedback, compared to the mere presentation of the information. Our results support the use of learning strategies that engage in active and explicit retrieval because, even if the retrieved information is wrong-when immediate feedback is provided-memory updating is promoted and errors are more likely to be corrected.

Incidental exposure to hedonic and healthy food features affects food preferences one day later.

Memories acquired incidentally from exposure to food information in the environment may often become active to later affect food preferences. Because conscious use of these memories is not requested or required, these incidental learning effects constitute a form of indirect memory. In an experiment using a novel food preference paradigm (n = 617), we found that brief incidental exposure to hedonic versus healthy food features indirectly affected food preferences a day later, explaining approximately 10% of the variance in preferences for tasty versus healthy foods. It follows that brief incidental exposure to food information can affect food preferences indirectly for at least a day. When hedonic and health exposure were each compared to a no-exposure baseline, a general effect of hedonic exposure emerged across individuals, whereas health exposure only affected food preferences for high-BMI individuals. This pattern suggests that focusing attention on hedonic food features engages common affective processes across the general population, whereas focusing attention on healthy food features engages eating restraint goals associated with high BMI. Additionally, incidental exposure to food features primarily changed preferences for infrequently consumed foods, having less impact on habitually consumed foods. These findings offer insight into how hedonic information in the obesogenic food environment contributes to unhealthy eating behavior that leads to overweight and obesity. These findings further motivate the development of interventions that counteract the effects of exposure to hedonic food information and that broaden the effects of exposure to healthy food information.

Imagination Reduces False Memories for Everyday Action Sentences: Evidence From Pragmatic Inferences.

Human memory can be unreliable, and when reading a sentence with a pragmatic implication, such as "the karate champion hit the cinder block," people often falsely remember that the karate champion "broke" the cinder block. Yet, research has shown that encoding instructions affect the false memories we form. On the one hand, instructing participants to imagine themselves manipulating the to-be-recalled items increase false memories (imagination inflation effect). But on the other hand, instructions to imagine have reduced false memories in the DRM paradigm (imagination facilitation effect). Here, we explored the effect of imaginal encoding with pragmatic inferences, a way to study false memories for information about everyday actions. Across two experiments, we manipulated imaginal encoding through the instructions given to participants and the after-item filler task (none vs. math operations). In Experiment 1, participants were either assigned to the encoding condition of imagine+no filler; pay attention+math; or memorize+math. In Experiment 2, the encoding instructions (imagine vs. memorize) and the filler task (none vs. math) were compared across four separate conditions. Results from the two experiments showed that imagination instructions lead to better memory, by showing a higher proportion of correct responses and better performance in a memory benefit index. Similarly, a significant reduction of false memories was observed across both experiments, even though a complementary Bayesian analysis only supported this conclusion for Experiment 1. The findings show that imaginal encoding improves memory, suggesting the engagement of a distinctiveness heuristic and source-monitoring process.

Break the Ice: a Survey on Socially Aware Engagement for Human-Robot First Encounters.

Society is starting to come up with exciting applications for social robots like butlers, coaches, and waiters. However, these robots face a challenging task: to meet people during a first encounter. This survey explores the literature that contributes to this task. We define a taxonomy based on psychology and sociology models: Kendon's greeting model and Greenspan's model of social competence. We use Kendon's model as a framework to compare and analyze works that describe robotic systems that engage with people. To categorize individual skills, we use three components of Social Awareness that belong to Greenspan's model: Social Sensitivity, Social Insight, and Communication. Under each section, we highlight some research gaps and propose research directions to address them. Through our analysis, we suggest significant research directions for enhanced first encounters. First, social scripts need to be evaluated under equal conditions. Second, interaction management and tracking for first encounters should consider state and observation uncertainties. Third, perception methods need lighter and robust integration in mobile platforms. Fourth, methods to explicitly define social norms are still scarce. Finally, research on social feedback and interaction recovery may fill the gaps of imperfect first encounters.

Learning what to inhibit: The influence of repeated testing on the encoding of gender and age information.

Psychological research has devoted considerable attention to the relationship between the multiple category dimensions that can be extracted from faces. In the present studies, we investigated the role of experience and learning on the way the social perceiver deals with multiple category dimensions. Specifically, we tested whether learning which of 2 dimensions is the most relevant to the task at hand influences the encoding and retrieval of both task-relevant and irrelevant dimensions. In our studies, participants went through several cycles, each consisting of a study and a test phase. We manipulated the structure of the tests such that participants were probed on only 1 category dimension (age or gender), despite viewing faces of both category dimensions in all study phases. We hypothesized that when participants were repeatedly tested on 1 dimension, they would proactively control their attention toward that specific dimension and away from the nonrelevant dimension. Five studies demonstrated that: (a) participants learned which dimension was test-relevant such that they gradually became faster and more accurate on that dimension; (b) when the gender dimension was test-relevant, participants were faster and more accurate retrieving information concerning the target faces' gender than age, while the opposite did not happen when the age dimension was test-relevant; and (c) this dominance of the gender dimension is mainly caused by the inhibition of the age dimension. Implications about the importance of previous experience and control for research on social categorization in general and research examining the interplay between gender and age are discussed.

How Your Power Affects My Impression of You.

In the present article, we investigate how a person's power affects the way we infer traits from their behavior. In Experiment 1, our results suggest that, when faced with behavioral descriptions about others, participants infer both positive and negative traits about powerless actors, whereas for powerful and control (power irrelevant) actors, only positive but no negative traits are inferred, an effect we call the benevolence bias. In the second experiment, (a) we replicate this effect, (b) we show that it does not depend on the specific traits used in Experiment 1, and (c) we show that it is also detected when an implicit measure of inferences is used. Experiment 3 further shows that this effect generalizes to a more generic power manipulation. Theoretical explanations for these findings are discussed.

Memory and conceptual learning of relevant and non-relevant items in item-method directed forgetting.

The present research investigates the fate of non-target information when people are trying to either intentionally memorise or forget target information. By using an object-based attentional manipulation within a directed forgetting paradigm (item-method), we show a directed forgetting effect (DFE, i.e., better memory for to-be-remembered (TBR) than for to-be-forgotten (TBF) items) for items that participants are explicitly instructed to attend but not for irrelevant items that happen to be part of the context. Alongside the classic DFE, we investigate how the category of the attended and unattended items are learned. The results obtained in three experiments, show that people can successfully learn only the category of the TBR attended items and that the DFE extends to new items that are related to the old TBR and TBF items (an effect that we call conceptual DFE). These results give us new insight about how TBR and TBF items are processed and conceptually learned.

Off the top of my head: Malleability and stability in natural categories.

Previous research has found that category representations are highly malleable knowledge structures, varying widely across different contexts and individuals. However, it has also been found that such malleability does not apply equally to all types of category information. The present research further investigates the representational malleability versus stability of natural taxonomic categories. Using perceptual fluency as means to induce malleability, we explored whether malleability is moderated by the degree of typicality of category information. In the first experiment, we found that fluency-based malleability only occurs for non-typical category information. In follow-up experiments, we investigated the boundary conditions under which such fluency-based malleability occurs. Namely, in Experiment 2, we showed that the effect of fluency on non-typical features disappeared when there is a sensory modality mismatch between study and test phases. Finally, in Experiment 3, we demonstrated that this effect reappears in the modality mismatch condition when participants are given a response deadline. The implications of these findings to current theories of category representation and the perceptual fluency literature are discussed.

The future is now: the impact of present fluency in judgments about the future.

Recent research has emphasised the role of episodic memory in both remembering past events and in envisaging future events. On the other hand, it has been repeatedly shown that judgments about past events are affected by the fluency with which retrieval cues are processed. In this paper we investigate whether perceptual fluency also plays a role in judgments about future events. For this purpose we conducted four experiments. The first experiment replicated recent findings showing that stimuli that are processed fluently tend to be wrongly recognised as having been encountered in the past outside the laboratory walls [Brown, A. S., & Marsh, E. J. (2009). Creating illusions of past encounter through brief exposure. Psychological Science, 20, 534-538. doi: 10.1111/j.1467-9280.2009.02337.x ]. Two follow-up experiments using Brown and Marsh's [(2009). Creating illusions of past encounter through brief exposure. Psychological Science, 20, 534-538. doi: 10.1111/j.1467-9280.2009.02337 ] task tested the influence of perceptual fluency on future judgments. The fourth and last experiment was designed to rule out a potential confounding factor in the two previous experiments. Across experiments, we found that people rely on fluency when making judgments about events that are yet to come. These results suggest that fluency is an equally valid cue for past and future judgments.

Inferential Costs of Trait Centrality in Impression Formation: Organization in Memory and Misremembering.

An extension of the DRM paradigm was used to study the impact of central traits (Asch, 1946) in impression formation. Traits corresponding to the four clusters of the implicit theory of personality-intellectual, positive and negative; and social, positive and negative (Rosenberg et al., 1968)-were used to develop lists containing several traits of one cluster and one central trait prototypical of the opposite cluster. Participants engaging in impression formation relative to participants engaging in memorization not only produced higher levels of false memories corresponding to the same cluster of the list traits but, under response time pressure at retrieval, also produced more false memories of the cluster corresponding to the central trait. We argue that the importance of central traits stems from their ability to activate their corresponding semantic space within a specialized associative memory structure underlying the implicit theory of personality.

"To-be-forgotten" statements become less true: Memory processes involved in selection and forgetting lead to truthfulness changes of ambiguous sentences.

What happens when people try to forget something? What are the consequences of instructing people to intentionally forget a sentence? Recent studies employing the item-method directed forgetting paradigm have shown that to-be-forgotten (TBF) items are, in a subsequent task, emotionally devaluated relative to to-be-remembered (TBR) items, an aftereffect of memory selection (Vivas, Marful, Panagiotidou & Bajo, 2016). As such, distractor devaluation by attentional selection generalizes to memory selection. In this study, we use the item-method directed forgetting paradigm to test the effects of memory selection and inhibition on truth judgments of ambiguous sentences. We expected the relative standing of an item in the task (i.e., whether it was instructed to be remembered or forgotten) to affect the truthfulness value of that item, making TBF items less valid/truthful than TBR items. As predicted, ambiguous sentences associated with a "Forget" cue were subsequently judged as less true than sentences associated with a "Remember" cue, suggesting that instructions to intentionally forget a statement can produce changes in the validity/truthfulness of that statement. To our knowledge, this is the first study to show an influence of memory processes involved in selection and forgetting on the perceived truthfulness of sentences.

Explaining the persistence of false memories: a proposal based on associative activation and thematic extraction.

This study aimed to analyse the effect of retention intervals on associative and thematic false memories. Two experiments, using two types of critical items that were either associatively or thematically related to studied material, were conducted. In both experiments, one group of participants performed a recognition test immediately after the presentation of lists, and another group performed the task one week later. In Experiment 1, the recognition test consisted of pairs of items with four response alternatives (both items had been presented, only the left item had been presented, only the right item had been presented or none of the items had been presented). Critical items were also manipulated so that they were either presented in or absent from the list. In Experiment 2, a standard recognition test that differed in the mode of presentation was used: self-paced or speeded response. Both experiments showed that associative critical items were more recognised than thematic critical items in the immediate condition. However, whereas associative critical items decayed after a one-week delay, thematic critical items were similarly recognised at both retention intervals. The findings of the present study suggest that each type of process - associative and thematic - behave differently over time.

The memory of what we do not recall: dissociations and theoretical debates in the study of implicit memory

Implicit memory reflects itself on situations in which previously acquired information is expressed, without awareness or intention. The study of implicit memory has had a profound impact on how researchers have investigated the human memory. In this paper, we review the main studies which have revealed dissociations between direct and indirect tests of memory, and address the two main theoretical approaches used to explain these dissociations: the processing view and the multiple systems view. We then describe recent neuroscience studies and discuss its contributions to help clarify the debate about the mechanisms involved in explicit and implicit memory. Finally, we critically analyze some questions and controversies surrounding this literature, such as (a) the transparency assumption and the contamination issue; and (b) the theoretical utility of the dissociations. We emphasize that the biggest challenge for future research is to develop comprehensive theories that integrate behavioral and neuroscience findings (AU)

Evaluating young and old faces on social dimensions: trustworthiness and dominance

In the present study we provide measures of dominance and trustworthiness of a subset of faces from the Productive Aging Laboratory (PAL) Face Database (Minear & Park, 2004). Recent research has shown that dominance and trustworthiness are central to social perception, and that they can be inferred from faces in milliseconds (Oosterhof & Todorov, 2008). A total of 286 faces from four age groups (18-29; 30-49; 50-69; 70-94) were presented and evaluated in dominance and trustworthiness. The same faces were also evaluated on other four dimensions: likeability, perceived age, attractiveness, and gender typicality. This information enriches the PAL Face Database, making it more valuable for researchers investigating faceprocessing mechanisms across the lifespan. The collected norms are available for download as supplemental materials (AU)

Stimulus-Response Bindings in the Go/NoGo Task: Effects on the Judged Typicality of Stimuli.

In the present paper, we explore the notion that judgments of typicality are dependent on the goal-relevancy of exemplars. However, we propose that relevancy can be derived from the response provided to stimulus, through the operation of stimulus-response bindings. Specifically, items associated with selection responses are tagged as "relevant" and will be subsequently judged as more typical of their categories, while stimuli associated with avoidance responses are tagged as "irrelevant" will be judged as less typical of their categories. We test this prediction with a Go-NoGo task with male and female faces. Results showed that (a) faces associated with a selection (Go) response were judged more typical of their gender category than faces associated with an avoidance (NoGo) response, and (b) these effects were more likely to be observed when the context is reactivated. Our results are consistent with the notion that representation of typicality is goal-oriented and contextually dependent.

Adapting to test structure: letting testing teach what to learn.

We propose that we encode and store information as a function of the particular ways we have used similar information in the past. More specifically, we contend that the experience of retrieval can serve as a powerful cue to the most effective ways to encode similar information in comparable future learning episodes. To explore these ideas, we did two studies in which all participants went through study-test cycles of single category lists while we manipulated the nature of the recognition tests. The recognition tests either included only same-category lures or only different-category lures. The experience of repeated testing leads participants to avoid conceptual-based strategies but only when conceptual knowledge was poorly diagnostic for recognition (i.e., in the same-category lures condition). In a second study with a similar manipulation, we showed that repeated testing with lures from the same category as study items improved performance in a final recall surprise test compared to conditions in which different-category lures were used. Such a difference is akin to the one obtained when encoding instructions focus on distinctive item features compared to cases in which the focus is on relational processing. We suggest that testing requirements lead to adaptive changes at encoding.

Too young to correct: a developmental test of the three-stage model of social inference.

The 3-stage model of social inference posits that people categorize behaviors and characterize actors or situations effortlessly, but they correct these characterizations with additional information effortfully. The current article tests this model using developmental data, assuming that the less cognitively demanding processes in the model (i.e., categorization, characterization) should appear earlier in development, whereas the more demanding correction process should not appear until later in development. Using 2 different paradigms, Studies 1 and 3 found that younger children failed to take situational information into account while characterizing the actor. Study 2 found that younger children failed to take dispositional information into account while characterizing the situation. In contrast, in these 3 studies, older children used the available information to correct their characterizations of the actors and of the situations. Consistent with the 3-stage model, during elementary school years, children start to integrate additional information when drawing explicit social inferences. In Study 4, children of all age levels used a prior expectancy to draw a dispositional inference, ignoring situational information, suggesting that characterizations based on prior expectancies about an actor are a highly efficient process, not contemplated by the model. The 4 studies together illustrate how developmental data can be valuably used to test adult socio-cognitive models, to extend their validity, or to simply further inform those models.

Buy three but get only two: the smallest effect in a 2 × 2 ANOVA is always uninterpretable.

Loftus (Memory & Cognition 6:312-319, 1978) distinguished between interpretable and uninterpretable interactions. Uninterpretable interactions are ambiguous, because they may be due to two additive main effects (no interaction) and a nonlinear relationship between the (latent) outcome variable and its indicator. Interpretable interactions can only be due to the presence of a true interactive effect in the outcome variable, regardless of the relationship that it establishes with its indicator. In the present article, we first show that same problem can arise when an unmeasured mediator has a nonlinear effect on the measured outcome variable. Then we integrate Loftus's arguments with a seemingly contradictory approach to interactions suggested by Rosnow and Rosenthal (Psychological Bulletin 105:143-146, 1989). We show that entire data patterns, not just interaction effects alone, produce interpretable or noninterpretable interactions. Next, we show that the same problem of interpretability can apply to main effects. Lastly, we give concrete advice on what researchers can do to generate data patterns that provide unambiguous evidence for hypothesized interactions.
