More than meets the gut: a prototype analysis of the lay conceptions of intuition and analysis.

Using a prototype approach, we assessed people's lay conceptions of intuition and analysis. Open-ended descriptions of intuition and analysis were generated by participants (Study 1) and resulting exemplars were sorted into features subsequently rated in centrality by independent participants (Study 2). Feature centrality was validated by showing that participants were quicker and more accurate in classifying central (as compared to peripheral) features (Study 3). Centrality ratings suggested a single-factor structure describing analysis but revealed that participants held lay conceptions of intuition as involving two different types of processes: (1) as an automatic, affective, and non-logical processing, and (2) as a holistic processing that can assist in problem-solving. Additional analyses showed that the centrality ratings of intuition's facets were predicted by participants' self-reported intuitive style, suggesting intuition is differently perceived by intuitive and non-intuitive people. We discuss the implications of these results for the study of intuition and analysis.

Meta-Analysis of Social Presence Effects on Stroop Task Performance.

In this paper, we conducted a meta-analytic review to examine the impact of social presence on individuals' performance on the Stroop task, shedding light on the cognitive processes underlying social facilitation. We followed PRISMA guidelines to identify and include 33 relevant studies in a multivariate random-effects meta-analysis. Our results show that social presence reliably modulates Stroop interference (a measure of cognitive control); specifically, participants exhibit lower Stroop interference when performing the task in the presence of others compared to performing it in isolation. We also found that the strength of the effect varies depending on the type of social presence: it is stronger with an attentive audience compared to an inattentive one, and null with an evaluative audience. Additionally, different features of the Stroop task itself moderate the effect; the effect is stronger for the classic version of the task compared to the semantic version, and for experiments that use mixed within-block trials compared to those with homogenous blocks. We also observed a negative relationship between the number of trials and the magnitude of the effect. Overall, these findings provide insights into the mechanisms by which the presence of others affects performance on the Stroop task, and how they align with social facilitation theories.

A Population-Based Cross-Sectional Study of Paediatric Coeliac Disease in Catalonia Showed a Downward Trend in Prevalence Compared to the Previous Decade.

(1) Background: Previous studies showed an increased prevalence and incidence of coeliac disease (CD) over time. The objective is to ascertain whether the CD prevalence in Catalonia (a region of Southern Europe) among children aged 1-5 is as high as previously found in 2004-2009; (2) Methods: From 2013 to 2019, 3659 subjects aged 1-5 years were recruited following the previously used methodology. Factors with a potential impact on CD prevalence were investigated; (3) Results: In 2013-2019, 43/3659 subjects had positive serology, giving a standardised seroprevalence of 12.55/1000 (95% CI: 8.92; 17.40), compared to 23.62 (13.21; 39.40) in 2004-2007. The biopsy-proven crude prevalence was 7.92/1000 (95% CI: 5.50; 11.30), and the crude prevalence based on ESPGHAN criteria was 8.74/1000 (95% CI: 6.20-12.30). In contrast to 2004-2009, we did not find differences in the seroprevalence rates between 1 and 2 years vs. 3 and 4 years of age (age percentage of change -7.0 (-29.5; 22.8) vs. -45.3 (-67.5; -8.0)). Rotavirus vaccination was the most remarkable potential protective factor (48% vs. 9% in 2004-2009; p < 0.0001), but not the time of gluten introduction. (4) Conclusion: The present study did not confirm a worldwide CD prevalence increase and emphasizes the need to perform prevalence studies over time using the same methodology in the same geographical areas.

Perceptual anchoring effects: Evidence of response bias and a change in estimates sensitivity.

INTRODUCTION: People's estimates of perceptual quantities are commonly biased by the contextual presence of other quantities (like numbers). In this study, we address assimilation anchoring effects (approximation of real quantities to contextual quantities) that occur for visually displayed proportions, defining a new methodological setting for the effect. METHOD: Similar to classic approaches, we asked participants across several trials whether the display contained a feature in a proportion higher or lower than "a randomly selected value" (relative judgments), and then estimated the feature proportions (absolute judgments). Across all trials, we presented seven anchors ranging from .20 to .80, each with a visually displayed representation of the same seven proportions (49 judgments in total). This allowed for a psychophysical approach to individual estimates and signal detection indexes, providing new insights into how the anchoring effect is generated in this setting. RESULTS: Our findings suggest that anchoring effects occur both as a bias (changes in response criteria) and as a change in the ability to discriminate stimuli (affecting sensitivity indexes). Moreover, anchors modulate the level of stimuli features for which estimates were more uncertain. Finally, our results indicate that anchor effects occur immediately in the first phase of the two-phase paradigm, leading to the availability of values for supporting absolute estimates. CONCLUSION: By using a psychophysical approach to the anchoring effects, for the first time, we could clarify that this effect is the result of both bias and changes in the ability to discriminate quantity.

Deontic signs increase control monitoring: evidence from a modified traffic flanker task.

Deontic norms are expected to impose individuals' control over their behavior. In this paper, we address such norms presented in traffic signs and test their influence over executive control functions. For Experiment 1, we develop a traffic flanker task in which the typical neutral arrows are replaced with traffic prohibition/obligation signs. Experiment 2 isolated the deontic aspect of the signs using simple arrows on red, blue, and green backgrounds and either primed them to be interpreted as traffic signs or as elements of a gaming console controller. Results in both studies show evidence of controlling context interferences more efficiently when dealing with deontic (traffic) signs than with simple arrows (Experiment 1) or with similar perceptive targets when primed with a deontic context than with a gaming context (Experiment 2). In both studies, obligation/blue signs mitigate flanker effects less than prohibition/red signs. Stimuli color affects the alertness of the cognitive system, with the color red being, by itself, a cue for increased control. Based on temporal analysis, we further discuss these results as evidence of an increase in proactive control that aims to prevent the occurrence of undesirable influence.

Easy to process, hard to control: Transient and sustained processing fluency impairs cognitive control adjustments to conflict.

Recent research suggests that the cognitive monitoring system of control could be using negative affective cues intrinsic to changes in information processing to initiate top-down regulatory mechanisms. Here, we propose that positive feelings of ease-of-processing could be picked up by the monitoring system as a cue indicating that control is not necessary, leading to maladaptive control adjustments. We simultaneously target control adjustments driven by task context and on a trial-by-trial level, macro-, and micro-adjustments. This hypothesis was tested using a Stroop-like task comprised trials varying in congruence and perceptual fluency. A pseudo randomisation procedure within different proportion of congruence conditions was used to maximise discrepancy and fluency effects. Results suggest that in a mostly congruent context participants committed more fast errors when incongruent trials were easy-to-read. Moreover, within the mostly incongruent condition, we also found more errors on incongruent trials after experiencing the facilitation effect of repeated congruent trials. These results suggest that transient and sustained feelings of processing fluency can downregulate control mechanisms, leading to failed adaptive adjustments to conflict.

How Does the Presence of Others Influence Control Inhibition? Contradictory Evidence Using an Antisaccade and Stop Signal Task.

Inhibitory control (IC) is defined as the (in)ability to change, suppress, or delay a response that is no longer required under the current circumstances. This ability was previously argued to increase in social contexts, based on Stroop's performance, showing that participants performed the Stroop task better in others' presence than alone. In this paper, we extend the testing of this same hypothesis to the use of two other tasks that Mitake et al. (2000) show to grasp the same IC ability; the Antisaccade and Stop signal tasks. If Stroop's performance was capturing the impact of the presence of others on CI abilities, the effect would generalize to performance on these tasks. This hypothesis was only generally supported by stop signal task performance; those in the presence condition were significantly more efficient than those in the alone conditions. For the Antisaccade tasks, evidence shows that higher levels of interference occurs in the presence of others condition for participants' fastest responses We discuss how this evidence contributes to the literature suggesting that the two tasks may index different constructs.

A standardised set of images for judgements of proportion.

In the present work, we present normative data for a set of 39 original clipart-style images that can be used as material in studies involving judgements of proportion. The original images are drawings that depict different day-to-day scenarios (e.g., lighted windows in a building; books on a shelf) and each has seven variants of different proportions (from 20% to 80%) belonging to different categories (discrete vs continuous; social vs non-social; natural vs artificial; stimuli physical dimensions; number of referents). Normative data for these images are presented in an interactive database (available at https://judgment-images-and-norms.shinyapps.io/estimates_interactive/ ), corresponding to the means of proportion estimates (in percentage form), the perceived ease of making such estimates, the perceived level of familiarity and liking for each image, and the relationships between these variables. In the paper, we analyse the data at an individual level, addressing how the latter judgements are related to the proportion estimates, how those estimates are related to objective proportions, and how these relationships are moderated by image category. The analyses presented in this paper aim to aid readers in selecting images that enable them to better address specific influences on proportional estimates or to control for those influences in their studies.

The effect of facial occlusion on facial impressions of trustworthiness and dominance.

Recognizing the role that facial appearance plays in guiding social interactions, here we investigated how occlusions of the bottom-face region affect facial impressions of trustworthiness and dominance. Previous studies suggesting that different facial features impact inferences on these traits sustain the hypothesis that wearing a face mask will differently affect each trait inference. And specifically, that trustworthiness impressions will be more disrupted by this type of face occlusion than dominance impressions. In two studies, we addressed this possibility by occluding the bottom face region of faces that were previously shown to convey different levels of dominance and trustworthiness, and tested differences in the ability to discriminate between these trait levels across occlusion conditions. In Study 1 faces were occluded by a mask, and in Study 2 by a square image. In both studies, results showed that although facial occlusions generally reduced participants' confidence on their trait judgments, the ability to discriminate facial trustworthiness was more strongly affected than the ability to discriminate facial dominance. Practical and theoretical implications of these findings are discussed.

That person is now with or without a mask: how encoding context modulates identity recognition.

Previous research has mostly approached face recognition and target identification by focusing on face perception mechanisms, but memory mechanisms also appear to play a role. Here, we examined how the presence of a mask interferes with the memory mechanisms involved in face recognition, focusing on the dynamic interplay between encoding and recognition processes. We approach two known memory effects: (a) matching study and test conditions effects (i.e., by presenting masked and/or unmasked faces) and (b) testing expectation effects (i.e., knowing in advance that a mask could be put on or taken off). Across three experiments using a yes/no recognition paradigm, the presence of a mask was orthogonally manipulated at the study and the test phases. All data showed no evidence of matching effects. In Experiment 1, the presence of masks either at study or test impaired the correct identification of a target. But in Experiments 2 and 3, in which the presence of masks at study or test was manipulated within participants, only masks presented at test-only impaired face identification. In these conditions, test expectations led participants to use similar encoding strategies to process masked and unmasked faces. Across all studies, participants were more liberal (i.e., used a more lenient criterion) when identifying masked faces presented at the test. We discuss these results and propose that to better understand how people may identify a face wearing a mask, researchers should take into account that memory is an active process of discrimination, in which expectations regarding test conditions may induce an encoding strategy that enables overcoming perceptual deficits.

Bad after bad is good: previous trial disfluency reduces interference promoted by incongruence.

Conflict and perceptual disfluency have been shown to lead to adaptive, sequential, control adjustments. Here, we propose that these effects can be additive, suggesting their integration into a general feeling of disfluent information processing. This hypothesis was tested using an interference task that dynamically mixed trials varying in legibility and/or congruence. Moreover, the manipulation of the proportion of congruent trials within the task allowed differentiating conditions in which these experiences of fluency may vary. Results showed that progressive increases in processing disfluency elicited a matching decrease in the interference of incongruent fluent trials. This linear effect was significant for all proportion of congruence conditions, although lower when incongruent trials were more frequent. These results highlight the role of feelings in the initiation of control and suggest that the monitoring system could be using changes in information processing fluency as a need-for-control signal.

Mapping health vulnerabilities: exploring territorial profiles to support health policies.

Vulnerability processes and effects, albeit of great importance to cohesion and territorial policies, are nonetheless still underexplored and narrowly operationalized in scientific research. In particular, most assessments rely on economic indicators and a limited territorial scale, which do not have the same analytic potential of a broader view at a national level with regional/municipal similarities, specificities, and inter-connections. This gap also applies to health-related vulnerabilities, which, stemming from a lack of socioeconomic and environmental resources, has increased during and after the economic crisis of the past decade. This paper aims to analyze the health vulnerability phenomena in Portugal from a spatial perspective. Following a Multiple Correspondence Analysis, different territorial profiles of social vulnerability associated with the population health condition and access to and use of "health services" are identified. We conclude by outlining the importance of adding the spatial context to health policies addressing vulnerabilities and suggest avenues for future research.

Resumo Os processos e os efeitos da vulnerabilidade, embora de grande importância para a coesão e políticas territoriais, ainda são pouco explorados e operacionalizados do ponto de vista científico. Na verdade, a maioria das avaliações baseia-se em indicadores económicos e em contextos territoriais muito específicos, não explorando o potencial analítico de uma visão mais ampla ao nível nacional, tendo por base as especificidades e as interconexões regionais / municipais. Essa lacuna é visível nas vulnerabilidades relacionadas com a saúde, que, decorrentes da falta de recursos sociais, económicos e ambientais, aumentaram durante e após a crise económica iniciada na década passada. O principal objetivo deste artigo consiste em analisar os fenómenos de vulnerabilidade associados à saúde em Portugal numa ótica territorial. Através da realização de uma Análise de Correspondência Múltipla, são identificados diferentes perfis territoriais de vulnerabilidade social associados ao "estado de saúde" dos indivíduos e ao acesso e uso de "serviços de saúde". Na conclusão do artigo, sublinha-se a importância de adicionar o contexto territorial às políticas de saúde que procuram encontrar respostas para fazer face aos desafios decorrentes de vulnerabilidades sociais e sugerem-se pistas para investigação futura.

Norms for 150 consumer products: Perceived complexity, quality objectivity, material/experiential nature, perceived price, familiarity and attitude.

Consumer products are widely used as stimuli across several research fields. The use of consumer products as experimental stimuli lacks, however, the support of normative data regarding product features variability. In this work, we provide a first set of norms for people's perceptions of 150 consumer products regarding six relevant dimensions: product perceived complexity, quality objectivity, material/experiential nature, perceived price, familiarity and attitude. Products available in this normative database showed good overall distribution across the range of the dimensions evaluated. Obtained correlations between some of these dimensions provided evidence of how they can be confounded across products, further justifying the need to control for these dimensions. These norms should aid future research by allowing researchers to select products according to specific attributes and achieve appropriate experimental control. The norms here provided should also aid consumer behavior practitioners (such as marketers and advertisers) by providing insights as to how consumers perceive products along relevant dimensions.

Experienced Category Variability Modulates the Impact of Context on Evaluative Judgments.

Data from two experiments show that the experienced structure of a category (i.e., as having high vs. low variability) modulates the impact of context on evaluative judgments of individual exemplars. Target objects (unfamiliar in Experiment 1 and familiar in Experiment 2) were primed with positive and negative images while varying the number (Experiment 1) or typicity (Experiment 2) of exemplars known from a category prior to the judgment task. The results show that evaluations of object valence were more influenced by valenced context cues in high than in low variability category conditions. These results are taken as evidence that more varied exemplar-based category representations facilitate context effects on stimulus evaluation.

Low rectal cancer treatment strategies: a cohort study assessing watch and wait.

PURPOSE: Treatment strategies for low rectal cancer have been evolving toward achieving less treatment morbidity with the same oncological success-we aimed to assess the results of the new watch and wait (W&W) strategy in our cohort. METHODS: A tertiary care cohort study was conducted. New patients with rectal adenocarcinoma up to 6 cm from the anal margin, cM0, locally staged higher than cT1N0, evaluated between November 2014 and October 2018, were included. All 93 patients received neoadjuvant radiotherapy ± chemotherapy. Re-evaluation was planned 8-12 weeks after the end of treatment. Patients showing clinical complete response (cCR) were given the choice of either to proceed to surgery or to enter W&W. RESULTS: Of the 93 patients, 82.8% were re-evaluated and 20.8% had cCR. Patients in clinical stages II/III were significantly less likely to achieve cCR than those in stage I (p = 0.017). After a mean follow-up of 17.44 months, there were 4 regrowths in the 16 patients under W&W, all submitted to R0 surgery, ypN0; there were no deaths or local recurrences; one patient with regrowth had distant recurrence. Sixty patients underwent direct surgery after a mean follow-up of 16.23 months; 3 patients had local and distant recurrences; 7 others had only distant recurrences; there were 8 deaths. There were no statistically significant differences between patients under W&W and patients who underwent direct surgery regarding local or distant recurrences, or death (p > 0.9; p = 0.44; p = 0.19, respectively). CONCLUSION: The W&W strategy for low rectal cancer achieved the same oncological outcomes as the traditional strategy while sparing some patients from surgery.

A meta-analytical review of the familiarity temporal effect: Testing assumptions of the attentional and the fluency-attributional accounts.

The current meta-analysis accumulates empirical findings for the familiarity temporal effect (FTE) in duration judgments (the duration of more familiar stimuli is judged to be longer than that of less familiar stimuli). It brings together data from 2 separate literatures: time perception and processing fluency. In doing so, this review offers more and stronger evidence for testing the reliability of the effect; it defines the relevant moderators for addressing the validity of the 2 main explanations for the FTE: the attentional and the fluency-attributional hypotheses. The analysis (random effect model) of a total of 128 experiments (N = 3,338) showed that the effect of familiarity on perceived short durations (seconds) is highly reliable (g = .52); the same (or a similar) effect also occurs for other fluency manipulations (g = .51). The analysis supports assumptions generated by both the attentional and the fluency-misattributional explanations, suggesting that more research is needed to understand their possible dynamic relationship. Hence, this meta-analysis provides important guidance for future research with regard to time estimates. (PsycINFO Database Record (c) 2020 APA, all rights reserved).

The perception of time is dynamically interlocked with the facial muscle activity.

Time perception relies on the motor system. Involves core brain regions of this system, including those associated with feelings generated from sensorimotor states. Perceptual timing is also distorted when movement occurs during timing tasks, possibly by interfering with sensorimotor afferent feedback. However, it is unknown if the perception of time is an active process associated with specific patterns of muscle activity. We explored this idea based on the phenomenon of electromyographic gradients, which consists of the dynamic increase of muscle activity during cognitive tasks that require sustained attention, a critical function in perceptual timing. We aimed to determine whether facial muscle dynamic activity indexes the subjective representation of time. We asked participants to judge stimuli durations (varying in familiarity) while we monitored the time course of the activity of the zygomaticus-major and corrugator-supercilii muscles, both associated with cognitive and affective feelings. The dynamic electromyographic activity in corrugator-supercilii over time reflected objective time and this relationship predicted subjective judgments of duration. Furthermore, the zygomaticus-major muscle signaled the bias that familiarity introduces in duration judgments. This suggests that subjective duration could be an embodiment process based in motor information changing over time and their associated feelings.

Relative to what? Dynamic updating of fluency standards and between-participants illusions of truth.

Previous research has shown that fluency effects are driven by discrepancies between current and baseline fluency. Thus, illusions of truth associated with repetition (which increases statement fluency and its perceived truth-value relative to new statements) are less likely to occur when participants judge pure lists of either all-repeated or all-new statements and comparisons are between-participants, than when participants judge mixed lists and comparisons are within-participants. Still, there are demonstrations of between-participants illusions of truth in the literature. In this manuscript, we explain the emergence of between-participants truth effects in terms of hypothetical dynamic updating of fluency standards. The findings of two experiments provide evidence for this hypothesis by showing that between-participants truth effects occur most strongly for the first elements of the statement list but are reduced over time. The findings suggest that the dynamics of fluency experiences contribute to the truth effect and should be taken into account when investigating illusions of truth.

Post-traumatic cyst-like lesion of cortical bone in children.

Post-traumatic cyst-like lesions are an infrequent complication of fractures in children. To our knowledge, no more than 30 cases have been reported in the English-language literature. They most commonly affect the distal radius following a greenstick or torus fracture. These cortical defects are often asymptomatic, non-expansile, and typically resolve spontaneously in 1-3 years. They appear proximal to the compression site and are usually identified 2-4 months after a minor fracture. These lesions have a distinct appearance on magnetic resonance imaging (MRI), with intralesional fatty marrow, which may help to differentiate it from other bone lesions. We review the literature and present 3 more cases studied with plain radiographs, computed tomography (CT), and MRI. Post-traumatic cyst-like lesions require no treatment, and therefore recognition of its typical features is crucial to prevent unnecessary invasive procedures.
