Sensitive to music? Examining the crossmodal effect of audition on sweet taste sensitivity.

Previous research has shown that music can influence taste perception. While most studies to date have focused on taste intensity ratings, less is known about the influence of musical stimuli on other parameters of taste function. In this within-subjects experiment (N = 73), we tested the effects of three sound conditions (High Sweetness soundtrack - HS; Low Sweetness soundtrack - LS; and Silence - S) on sweet taste sensitivity, namely, detection and recognition. Each participant tasted nine samples of sucrose solutions (from 0 g/L to 20 g/L) under each of the three sound conditions in counterbalanced order. We assessed the lower concentrations at which participants were able to detect (detection threshold) and correctly identify (recognition threshold) a taste sensation. Additionally, the intensity and hedonic ratings of samples above the recognition threshold (7.20 g/L) were analyzed. Affective variations (valence and arousal) in response to the sound conditions were also assessed. Although music did not lead to significant differences in mean detection and recognition thresholds, a larger proportion of sweet taste recognitions was observed at a near-threshold level (2.59 g/L) in the HS condition. The intensity and hedonic ratings of supra-threshold conditions were unaffected by the music condition. Significant differences in self-reported mood in response to the sound conditions were also observed. The present study suggests that the influence of music on the sweet taste perception of basic solutions may depend on the parameter under consideration.

Is it the Child's Fault? Maternal Attributions in Child Abuse and Neglect.

BACKGROUND: Among the parental cognitions explaining maladaptive parenting, attributions about a child's misbehavior seem important. However, there is little research on neglectful parents, and the different patterns of parental attributions associated with child abuse and child neglect are still underexplained. The current study examines parental attributions associated with child abuse and child neglect. METHOD: Mothers ( N = 218) were asked to evaluate vignettes describing child transgressions, half of which were followed by situational information. Child abuse and child neglect were evaluated through mothers' and professionals' reports. RESULTS: Preliminary results indicated that the child's age and maternal socioeconomic status were significantly correlated with attributions and child abuse and neglect scores and thus were controlled in the models. The results from hierarchical regressions indicated that dispositional attributions were associated with higher abuse scores (reported by mothers), even in the presence of situational information. Likewise, dispositional attributions were associated with higher neglect scores (reported by professionals), but the effect was no longer significant in the presence of situational information. CONCLUSIONS: These findings contribute to the current socio-cognitive approaches to child maltreatment and provide relevant input for understanding the different attributional mechanisms underlying child abuse and neglect.

The influence of consonant wanderings and facial expressions in warmth and competence judgments.

ABSTRACTThe preference for usernames whose oral pronunciation implies inward wandering articulatory movements over those involving outward movements - the in-out effect - has been shown to shape person perception judgments. Across three studies, we further tested the boundary conditions to this effect by combining the manipulation of the articulation direction of mock online usernames with one of the most critical cues for interpersonal judgments - facial expressions. As expected, users displaying smiling faces were rated as warmer and more competent than those displaying angry expressions. Notably, even in the presence of such diagnostic cues for social judgment, the articulatory activity involved in pronouncing a person's name still affected the impressions formed, particularly in the warmth dimension. These results show that the in-out effect did not vanish even when highly diagnostic visual information was available. Overall, the current work further emphasises the role of sensorimotor experience in person perception while providing additional evidence for the in-out effect, its boundary conditions, and potential mechanisms.

Collaborative inhibition effect: the role of memory task and retrieval method.

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 effect (Weldon and Bellinger, J Exp Psychol Learn Memory Cogn 23(5):1160-1175, 1997). This is arguably the case because group members have conflicting 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 effect 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 effect 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 effect was eliminated. Taken together, these results further support retrieval strategies disruption as an explanation for the collaborative inhibition effect.

Condom Use Beliefs Differ According to Regulatory Focus: A Mixed-Methods Study in Portugal and Spain.

Reports worldwide have been showing increasing rates of sexually transmitted infections (STIs) and condomless sex in recent years. Research has identified several individual and situational variables that can determine the decision to use condoms or forgo their use. We argue that such a decision can also be shaped by motives related to pleasure and safety (i.e., regulatory focus in sexuality). Using open ended questions, we asked 742 Portuguese and Spanish adults to indicate situations and reasons that could inform the decision making process with casual partners and the functions/attributes related to condoms. Using thematic analyses, we coded the drivers of condomless sex and condom use into themes and subthemes, and computed their frequencies. Using quantitative measures, we also asked participants to indicate their condom use expectancies and perceived barriers. Comparing participants according to regulatory focus revealed some differences. Pleasure promotion participants were more likely to consider that condom use decision making is driven by unexpectedness, pleasure, and intimacy pursuit, attached more pleasure reduction functions to condoms, expected more negative outcomes in condom use, and endorsed more sensation and partner barriers in condom use. In contrast, disease prevention participants were more likely to consider that condom use decision making is driven by adequate sexual education, responsibility, and behavioral control, and attached more health protective functions to condoms. These differences can inform the development of tailored intervention and awareness campaigns aimed at helping people to use condoms more consistently with casual partners and to avoid behaviors that put them at risk of STI transmission.

Prevent2Protect Project: Regulatory Focus Differences in Sexual Health Knowledge and Practices.

The way people perceive risks and make decisions about their health is regulated by two motivational systems-prevention of harm or promotion of pleasure. People more focused on prevention strive to avoid negative outcomes and enact more health-protective behaviors. In contrast, people more focused on promotion strive to attain positive outcomes and take more risks with their health. Building upon recent evidence extending this framework to sexual behaviors and health, we conducted a pre-registered online survey ( OSF ) with Portuguese and Spanish adults (N = 742; Mage = 31.42, SD = 9.16) to examine whether self-reported STI knowledge and sexual health practices differ based on predominant regulatory focus. This study was part of the Prevent2Protect project ( OSF ). Results showed that prevention-focused participants had heard about more STIs and retrieved more of their knowledge from scientific sources but had been tested for fewer STIs in the past. In contrast, promotion-focused participants indicated they had specific knowledge about more STIs, retrieved more of their knowledge from medical and peer sources, and had been tested for more STIs in the past. They also reported more frequent STI testing, using free testing facilities or asking their family practice doctor to get tested, more routine sexual health check-ups, and more use of other contraceptive methods, such as birth control pills. These results remained unchanged after controlling for demographic differences. Overall, our findings showed that different motives in sexuality shape sexual health knowledge and sexual health practices.

Norms for pictures of proper names: contrasting famous people and well-known places in younger and older adults.

Proper names comprise a class of labels that arbitrarily nominate specific entities, such as people and places. Compared to common nouns, retrieving proper names is more challenging. Thus, they constitute good alternative semantic categories for psycholinguistic and neurocognitive research and intervention. The ability to retrieve proper names is known to decrease with aging. Likewise, their retrieval may differ across their different categories (e.g., people and places) given their specific associated knowledge. Therefore, proper names' stimuli require careful selection due to their high dependence on prior experiences. Notably, normative datasets for pictures of proper names are scarce and hardly have considered the influence of aging and categories. The current study established culturally adapted norms for proper names' pictures (N = 80) from an adult sample (N = 107), in psycholinguistic measures (naming and categorization scores) and evaluative dimensions (fame, familiarity, distinctiveness, arousal, and representational quality). These norms were contrasted across different categories (famous people and well-known places) and age groups (younger and older adults). Additionally, the correlations between all variables were examined. Proper names' pictures were named and categorized above chance and overall rated as familiar, famous, distinctive, and of high representational quality. Age effects were observed across all variables, except familiarity. Category effects were occasionally observed. Finally, the correlations between the psycholinguistic measures and all rated dimensions suggest the relevance of controlling for these dimensions when assessing naming abilities. The current norms provide a relevant aging-adapted dataset that is publicly available for research and intervention purposes.

The spatial grounding of politics.

In three studies, we advance the research on the association between abstract concepts and spatial dimensions by examining the spatial anchoring of political categories in three different paradigms (spatial placement, memory, and classification) and using non-linguistic stimuli (i.e., photos of politicians). The general hypothesis that politicians of a conservative or socialist party are grounded spatially was confirmed across the studies. In Study 1, photos of politicians were spontaneously placed to the left or right of an unanchored horizontal line depending on their socialist-conservative party affiliation. In Study 2, the political orientation of members of parliament systematically distorted the recall of the spatial positions in which they were originally presented. Finally, Study 3 revealed that classification was more accurate and faster when the politicians were presented in spatially congruent positions (e.g., socialist politician presented on the left side of the monitor) rather than incongruent ones (e.g., socialist on the right side). Additionally, we examined whether participants' political orientation and awareness moderated these effects and showed that spatial anchoring seems independent of political preference but increases with political awareness.

The Distinctive Pattern of Declarative Memories in Autism Spectrum Disorder: Further Evidence of Episodic Memory Constraints.

This study examines declarative memory retrieval in ASD depending on the availability and access to stored conceptual knowledge. Fifteen autistic participants and a matched control group of 18 typically-developed (TD) volunteers completed a Remember-Know paradigm manipulated by encoding-type (categorical, perceptual) and item-typicality (high-typical, low-typical). The autistic group showed worse and slower recognition and less recollection but equivalent familiarity-based memories compared to TDs. Notably, low-typical items did not improve their memories as they did for TDs, likely due to difficulties in matching low-fit information to the stored schema. Results suggest that memory decline in ASD may derive from the episodic system and its dynamics with the semantic system. These findings may inform interventional strategies for enhancing learning abilities in ASD.

Two Cultural Processing Asymmetries Drive Spatial Attention.

Cultural routines, such as reading and writing direction (script direction), channel attention orientation. Depending on one's native language habit, attention is biased from left-to-right (LR) or from right-to-left (RL). Here, we further document this bias, as it interacts with the spatial directionality that grounds time concepts. We used a spatial cueing task to test whether script direction and the grounding of time in Portuguese (LR, Exp. 1) and Arabic (RL, Exp. 2) shape visuomotor performance in target discrimination. Temporal words (e.g., tomorrow, yesterday) were presented as cues in two modalities: visual (Exp. 1-2) and auditory (Exp. 1). Gaze movement (Exp. 1) and speed of discrimination decisions (Exp. 1-2) of targets presented to the left or right sides of the screen were assessed. As predicted, the interaction between target location and time concepts was significant across both modalities and linguistic communities. Additionally, LR participants detected the target on the right side of the screen faster after a future word than the target on the left side of the screen after a past word cue. In contrast, RL participants detected the target on the left side of the screen faster when the cue word was a future word than the target on the right side of the screen cued by a past word. In both modalities, the initial eye-gaze movement (Exp. 1) was responsive to the cue's time referent, further confirming that time orients attention. An additional bias was observed for the first fixation onset, which landed earlier on the target set that matched habitualized spatial routines. We conclude that scanning regularities are shaped by writing habits and bodily grounded categorical features.

Perceived Associations between Excessive Sugar Intake and Health Conditions.

Excessive sugar intake represents an increased risk of developing non-communicable diseases (e.g., obesity, cardiometabolic diseases, and dental diseases). Still, it is unclear whether people are aware of these adverse health outcomes. The current study systematically examined the extent to which people associate health conditions with excessive sugar intake. Participants (N = 1010 Portuguese volunteers) freely reported all health conditions they associated with excessive sugar consumption and rated the strength of these associations for eight specific health conditions. All participants reported health conditions associated with excessive sugar intake, with the most frequent being risk factors for cardiometabolic diseases (e.g., diabetes), cardiovascular diseases, oral problems, oncological and mental health conditions. Moreover, participants considered diabetes, overweight/obesity, and oral problems as being the conditions most related to excessive sugar intake. Women, participants with children in the household, and experts in health/nutrition rated excessive sugar intake as being more strongly linked to some of the health conditions. The identification of the health conditions that people associate with excessive sugar consumption may inform policymakers, educators, and health professionals and support interventions targeting the general public or specific groups (e.g., overweight people) in raising awareness of potential adverse health outcomes and, ultimately, contribute to reducing sugar intake.

Evaluating the Adequacy of Emoji Use in Positive and Negative Messages from Close and Distant Senders.

Computer-mediated communication allows people to communicate across several contexts (e.g., friends, professional settings) by using video-based or text-based channels. In the latter case, communication lacks nonverbal cues (e.g., tone of voice) that are critical to message interpretation. Including emoji can help express emotion and reinforce or clarify the meaning of a message. However, the benefits of using emoji are likely to depend on the context (e.g., the relationship between interlocutors) and the messages' features (e.g., the valence of the message). To date, studies have not systematically and empirically examined how the use of emoji is perceived across different communication scenarios. In the current study, we asked 175 participants (49.5 percent women; Mage = 36.32, SD = 12.22) to imagine receiving either a negative or a positive message from 22 senders (e.g., friend; bank manager) and to indicate, for each case, how much they would like to receive an emoji and how useful and appropriate they considered the use of emoji. These ratings were combined into a single index of emoji use adequacy. Based on factor analysis, the 22 scenarios were aggregated in distant and close scenarios. Overall, results showed that participants considered emoji use more inadequate in distant (vs. close) scenarios and for negative (vs. positive) messages. These findings suggest that the perceived benefits of emoji use for text-based communication may not be generalized to all text-based communication contexts, such that relationship proximity and message valence should not be overlooked. Implications for the fields of consumer psychology and communication are discussed.

Conceptual knowledge modulates memory recognition of common items: The selective role of item-typicality.

This work examines the influence of stored conceptual knowledge (i.e., schema and item-typicality) on conscious memory processes. Specifically, we tested whether item-typicality selectively modulates recollection and familiarity-based memories as a function of the availability of a categorical schema during encoding. Experiment 1 manipulated both encoding type (categorical vs. perceptual) and item-typicality (typical vs. atypical) in a single Remember-Know paradigm. Experiment 2 replicated and extended the previous study with a complementary source-memory task. In both experiments, we observed that typical items led to more Guess responses, while atypical items led to more Remember responses. These findings support the idea that the activation of a congruent categorical schema selectively enhances familiarity-based memories, likely due to the bypassing of the activated mechanisms for novel information. In contrast, atypical items improved recollective-based memories only, suggesting that their lesser fit with the stored prototype might have triggered those novelty processing mechanisms. Moreover, atypical items enhanced memory in the categorical condition for both item recognition and recollection memories only, suggesting an episodic gain due to inconsistency/novelty. The source memory results gave further credence to the argument that "Remember" judgments were based on truly recollective experiences and presented the same interaction between encoding type and item-typicality observed in recollective-based memories. Overall, the results suggest that the supposedly opposite conceptual knowledge effects actually coexist and interact, albeit selectively, in the modulation of recollection and familiarity processes.

The Effect of Simultaneously Presented Words and Auditory Tones on Visuomotor Performance.

The experiment reported here used a variation of the spatial cueing task to examine the effects of unimodal and bimodal attention-orienting primes on target identification latencies and eye gaze movements. The primes were a nonspatial auditory tone and words known to drive attention consistent with the dominant writing and reading direction, as well as introducing a semantic, temporal bias (past-future) on the horizontal dimension. As expected, past-related (visual) word primes gave rise to shorter response latencies on the left hemifield and future-related words on the right. This congruency effect was differentiated by an asymmetric performance on the right space following future words and driven by the left-to-right trajectory of scanning habits that facilitated search times and eye gaze movements to lateralized targets. Auditory tone prime alone acted as an alarm signal, boosting visual search and reducing response latencies. Bimodal priming, i.e., temporal visual words paired with the auditory tone, impaired performance by delaying visual attention and response times relative to the unimodal visual word condition. We conclude that bimodal primes were no more effective in capturing participants' spatial attention than the unimodal auditory and visual primes. Their contribution to the literature on multisensory integration is discussed.

Parental perceptions and practices regarding sugar intake by school-aged children: A qualitative study with Portuguese parents.

Excessive sugar intake is one of the factors contributing to the alarming rates of childhood obesity and overweight in Portugal. Children's preferences and food consumption patterns are largely determined by the foods that are more familiar to them. Parents and caregivers are responsible for shaping children's eating habits since they are the ones who choose the food available in the household. The present study explores parental perceptions about sugar and sugar intake and its consequences on children's health. Moreover, we also examined the practices that parents use to regulate their children's diet, namely, to promote the consumption of desired foods (e.g., vegetables) and limit the intake of undesired food (e.g., sweets), and the perceived barriers and facilitators of sugar intake regulation. To this end, 42 interviews were conducted with parents of school-aged children (ages 6-10 years). A thematic analysis revealed that parents perceive sugar as highly negative (e.g., "evil", "poison", "addiction") and its consumption as harmful (e.g., hyperactivity; overweight). Nonetheless, the view that sugary food consumption is not necessarily problematic was also common. Indeed, most parents considered that sugar intake should be regulated but not forbidden. To control the intake of sugary foods (e.g., sodas, cookies), they reported using strategies such as restriction, explanation, or negotiation. Several barriers to sugar intake regulation were identified (e.g., birthday parties, parents' lack of knowledge), but also a few facilitators (e.g., bringing food from home to school). Our findings may inform the development of interventions or policies to promote healthier eating habits in school-age children.

When vowels make us smile: the influence of articulatory feedback in judgments of warmth and competence.

In six studies (N=725), we extended the articulatory feedback hypothesis to person perception, examining how words featuring /i:/ sounds that activate the zygomaticus major muscle and words featuring /u:/ sounds activating the orbicularis oris muscle affect preference, warmth, and competence judgments of mock-usernames. Users with usernames including /i:/, in contrast to /u:/ sounds, were always preferred and judged as warmer and more competent. The impact of this manipulation in shaping preference as well as judgments on the core dimensions of social perception confirms the stability of the vowel-emotion link and the role of articulatory feedback in social information processing.

RealPic: Picture norms of real-world common items.

Pictures are often used as stimuli in several fields, such as psychology and neuroscience. However, co-occurring image-related properties might impact their processing, emphasizing the importance of validating such materials to guarantee the quality of research and professional practices. This is particularly relevant for pictures of common items because of their wide applicability potential. Normative studies have already been conducted to create and validate such pictures, yet most of them focused on stimulus without naturalistic elements (e.g., line drawings). Norms for real-world pictures of common items are rare, and their normative examination does not always simultaneously assess affective, semantic and perceptive dimensions, namely in the Portuguese context. Real-world pictures constitute pictorial representations of the world with realistic details (e.g., natural color or position), thus improving their ecological validity and their suitability for empirical studies or intervention purposes. Consequently, the establishment of norms for real-world pictures is mandatory for exploring their ecological richness and to uncover their impact across several relevant dimensions. In this study, we established norms for 596 real-world pictures of common items (e.g., tomato, drum) selected from existing databases and distributed into 12 categories. The pictures were evaluated on nine dimensions by a Portuguese sample. The results present the norms by item, by dimension and their correlations as well as cross-cultural analyses. RealPic is a culturally based dataset that offers systematic and flexible standards and is suitable for selecting stimuli while controlling for confounding effects in empirical tasks and interventional applications.

The in-out effect: examining the role of perceptual fluency in the preference for words with inward-wandering consonantal articulation.

Words whose consonantal articulation spots wander inward, simulating ingestion movements, are preferred to words featuring the opposite consonantal articulation direction, that is, resembling expectoration movements. The underlying mechanism of this so-called in-out effect is far from settled. Contrary to the original explanation proposing an oral approach-avoidance mechanism, recent evidence has been used to support an oral motor-fluency mechanism, suggesting that inward words are preferred because they may be more common and/or easier to pronounce. Across six experiments (n = 1123), we examined the impact of different fluency sources in the emergence of the in-out effect. The preference for inward-wandering words persisted both with classical font type and figure-ground contrast fluency manipulations, and no systematic additive effects were observed. The in-out effect was also replicated for the first time with a between-participant design. These results suggest that the in-out effect may be permeable to fluency manipulations, but it is not dependent upon a plain fluency mechanism.

Surviving in a second language: survival processing effect in memory of bilinguals.

Human memory likely evolved to serve adaptive functions, that is, to help maximise our chances of survival and reproduction. One demonstration of such adaptiveness is the increased retention of information processed in survival contexts, the so-called Survival Processing Effect (SPE). This study examined this effect in a native (L1) and in a second language (L2). This comparison is relevant to explore if emotionality is involved in the SPE, as emotional activation seems to be larger in L1 than in L2. Following the original survival processing procedure, participants rated the relevance of information to the survival and moving scenarios and performed a recognition (Experiment 1) or a free recall (Experiment 2) task in L1 or L2. In both experiments, the SPE was replicated in L1 but not in L2. The absence of the effect when emotional activation is less likely suggests that emotionality might play a role in the survival processing effect; nevertheless, additional studies are needed to further investigate this hypothesis.

A qualitative study about college students' attitudes, knowledge and perceptions regarding sugar intake.

Excessive sugar intake has been associated with multiple health conditions (e.g., higher risk for non-communicable diseases). Hence, health organizations have issued guidelines defining the maximum daily intake of free or added sugars. However, data from several countries suggests that these guidelines are rarely met, particularly by young adults. For example, almost half of Portuguese adolescents and young adults exceed the recommended sugar intake. In this work, we aim to further explore college students' attitudes, knowledge, and perceptions about sugar intake, as well as about sugar intake guidelines. A thematic analysis on data from five focus groups (N = 40) indicated that participants reported difficulty in the comprehension of added/free sugars definition and sugar intake recommendations. Overall, attitudes toward sugar were ambivalent. Sugar was simultaneously perceived as pleasurable and needed, but also as addictive and harmful. Although aware of the potential negative health outcomes associated with excessive sugar intake, most participants did not perceive being at risk due to their youth, exercise habits, or type of diet. The few concerns expressed were mostly associated with the negative impact of high sugar intake on body image (e.g., weight gain). The main barriers to reducing sugar intake identified were environmental (e.g., time restrictions, food available at the university). Still, participants could identify several individual strategies to effectively regulate sugar intake. By identifying knowledge gaps and sources of bias related to sugar consumption, our findings are useful to inform future interventions aiming to address the problem of high sugar intake among university students.
