Face masks can impact processing a narrative in sign language, affecting several metacognitive dimensions of understanding (i.e., perceived effort, confidence and feeling of understanding). However, to what extent this is modulated by sign language proficiency remains an open question. Thirty deaf adults were administered a narrative in Italian Sign Language (LIS), signed in three different visual conditions: no mask, transparent mask, opaque mask. In addition, they completed a Sentence Reproduction Task in LIS (LIS-SRT) to measure their sign language proficiency. Results showed that some of the error types in the LIS-SRT have significant correlations with performance in the comprehension task, revealing external validity for this sentence repetition test. Crucially, while sign language proficiency did not modulate the impact of face-masks on narrative comprehension, the metacognitive outcomes were clearly influenced by the interaction between LIS proficiency and visual conditions. Skilled signers experienced less effort and higher levels of confidence and feeling of understanding, whereas these subjective experiences were greatly impacted by visual conditions in less proficient signers. We discuss these findings in reference to cognitive load, thus also extending the construct of "listening effort" to sign languages. In addition, we relate differences in cognitive load in skilled vs. less proficient signers to the ability to extract and process at the same time multiple types of linguistic elements from the flow of signs (multilinear processing of sign language).

The objective was to examine differences in the gait-specific cognitive representation structures between individuals after total knee- (TKA) and after total hip-joint arthroplasty (THA). The cognitive representation structure was compared between three groups: 1. three months after TKA (n = 12), 2. three months after THA (n = 12), and 3. healthy control group (CG) (n = 12) using the structural dimensional analysis of mental representation (SDA-M). Additionally, perceived joint function was rated by either the KOOS, JR. or HOOS, JR. Mean distribution of perceived joint function was not significantly different between the TKA (60.35 ± 11.2) and THA group (68.01 ± 13.8) (t = - 1.425; p = .173). In the cognitive representation structure, the THA group exhibited functional differences from the TKA group and control group, both of which showed a functional structure. Three months after hip joint replacement the gait-specific cognitive representation structure seems to reflect joint function-specific deviations. Therefore, focussing on functional recovery of cognitive gait representation may facilitate gait rehabilitation in individuals after hip replacement.

As technological interfaces are relatively new cultural tools, regular interaction can lead to new psychological phenomena, like the baby duck syndrome, where users favor old interfaces over updates. This syndrome is seen as a cognitive bias in human-computer interaction. Two studies were conducted: Study 1 on an Airbnb app (old vs. new versions), and Study 2 on a self-developed website (blue vs. purple design). Subjects completed sequential five usability tasks in two blocks with the resting between. Experimental groups engaged with different interface versions, while control groups used the same one. After completing tasks, subjects filled questionnaires about interface interaction. Study 1 showed significantly higher preference for the old Airbnb version, though scores varied by group. Study 2 revealed a trend of reduced scores in experimental groups on second assessment, not seen in controls. Version-based rating differences were insignificant. Overall, Studies 1 and 2 indicated baby duck syndrome is challenging to study in labs, suggesting it emerges when users are genuinely engaged with the interface. This article has both theoretical and experimental significance for studying the emergence of psychological phenomena in human-digital interaction. As a practical application, the obtained results can be useful for correct development updates for interfaces.

Although the effects of emotionality on word processing might be modulated by lexical category, a body of extant literature has tended to obviate the need of considering this factor. In this study, we attempted to address how lexical category modulates the effects of emotionality on L2 word processing. To this end, event-related potentials (ERPs) were recorded from a group of late proficient Chinese-English bilinguals while they performed a lexical decision task with a set of tightly matched negative, positive, and neutral words across three lexical categories (nouns, verbs, adjectives). The results revealed a P2 effect, an N400 effect, as well as an LPC effect for word emotionality. Moreover, an interaction between word emotionality and lexical category occurred within the N400 and LPC time windows over fronto-central electrodes, reflecting that the N400 displayed a smaller amplitude for positive nouns and verbs than for their neutral counterparts, as well as for negative as opposed to neutral adjectives, and that the LPC showed a larger amplitude for positive relative to neutral nouns, as well as for positive and negative adjectives than for their neutral counterparts. These results provide initial electrophysiological evidence for the modulation of lexical category to the emotionality effects on L2 word processing at the different stages and highlight the importance of lexical category in research on L2 emotional word processing.

Developmental dyscalculia (DD) is a specific mathematics learning disorder, characterized by the atypical development of number sense, arithmetic calculation, and atypical development of brain structures and brain activations in core brain regions for number processing. The current study examined the intervention effect of a 2-month abacus training on DD students. Results showed that compared with the non-trained control group, the DD students with abacus training showed higher scores in number sense, calculation, and sustained attention abilities. Additionally, a larger percentage of students in the abacus group showed improvements in the DD screening tasks compared to the control group. The current finding indicated that abacus training or abacus courses can be used as a tool for further DD intervention.

Operant keypress tasks in a reinforcement-reward framework where behavior is shaped by its consequence, show lawful relationships in human preference behavior (i.e., approach/avoidance) and have been analogized to "wanting". However, they take 20-40 min as opposed to short non-operant rating tasks, which can be as short as 3 min and unsupervised, thus more readily applied to internet research. It is unknown if non-operant rating tasks where each action does not have a consequence, analogous to "liking", show similar lawful relationships. We studied non-operant, picture-rating data from three independent population cohorts (N = 501, 506, and 4019 participants) using the same 7-point Likert scale for negative to positive preferences, and the same categories of images from the International Affective Picture System. Non-operant picture ratings were used to compute location, dispersion, and pattern (entropy) variables, that in turn produced similar value, limit, and trade-off functions to those reported for operant keypress tasks, all with individual R² > 0.80. For all three datasets, the individual functions were discrete in mathematical formulation. They were also recurrent or consistent across the cohorts and scaled between individual and group curves. Behavioral features such as risk aversion and other interpretable features of the graphs were also consistent across cohorts. Together, these observations argue for lawfulness in the modeling of the ratings. This picture rating task demonstrates a simple, quick, and low-cost framework for quantitatively assessing human preference without forced choice decisions, games of chance, or operant keypressing. This framework can be easily deployed on any digital device worldwide.

Humans demonstrate spontaneous sensitivity to other people's perspectives on object identities in online tasks. Evidence shows that this not only involves representing the mere discrepancy between perspectives, but the content of such perspectives as well (level-2 perspective taking/L2PT). However, this evidence comes from studies using culturally grounded symbols which leaves open the possibility that having extensive, easily accessible background knowledge about an object is necessary for the L2PT effect. Experiment 1 tested this by comparing L2PT across two groups: one performing a verification task on Arabic numbers, and one on newly learnt symbol-label pairs. In both groups, half of the visual stimuli was symmetrical, while half was asymmetrical. In both cases, there was a joint condition: participants performed the task in parallel with a partner, observing stimuli from opposite angles, thus having conflicting interpretations for asymmetric characters. Furthermore, they also performed the verification task individually, while their partner had no visual access to the stimuli. We found an interference effect in both groups. However, while the effect was stable in the number group, it diminished over time in the symbol group. Experiments 2a and 2b demonstrated that the complexity of the recently learnt symbols has an influence on spontaneous L2PT: the same procedure with more complex symbols did not elicit any interference effect. Our results show that online L2PT is not limited to objects that participants have proficiency in identifying. Nevertheless, the L2PT effect seems to diminish when participants have to process increasingly complex novel symbols.

Many individuals encounter situations that may elicit body-related concerns and impact how they think and feel about their weight, daily habits, and physical attractiveness. Research shows body image threats can predict poor health behaviors, but approaching those difficult moments with self-compassion-being kind, forgiving, and nonjudgmental-may reduce the impact of that threat and promote engagement in positive health behaviors. However, trait rumination, or tending to perseverate on negative events, may both dampen the benefits of a self-compassionate state and predict poor health behaviors. The present study examined whether a brief self-compassion writing exercise, after recalling a negative body-related event, predicted intent to perform health-promoting behaviors, and whether trait rumination attenuated this relationship. Participants (N = 217) completed a measure of trait rumination, underwent a body image threat, and were randomly assigned to cope with self-compassion or a distraction. Subsequently, participants completed a measure of health behavioral intentions. Analyses revealed participants in the self-compassion condition reported greater health-promoting behavioral intentions compared to control, with no significant main effect of trait rumination. However, a condition-by-rumination interaction emerged, suggesting the self-compassion condition was associated with higher health behavioral intentions, but only for participants with low trait rumination levels. These effects washed out when controlling for participants' self-rated health. The findings suggest that a self-compassion practice can help mitigate the adverse effects of a body image threat and facilitate health-promoting behavioral intentions, although its efficacy may depend on individual levels of trait rumination and perceived health.

Metaverse virtual reality (VR) technology offers an environment that provides a sense of presence that cannot be achieved through traditional online interactions. Although this technology is used in education and industry, challenges remain to be overcome for further penetration into society. In this study, we conducted an experiment using a risk preference task in blue and red spaces to verify color impressions and their effects in VR environments. Consistent with previous studies, high calmness was observed in the blue space. However, contrary to expectations, the risk preference task results showed risk-averse behavior in red space but not in blue space. Therefore, conventional color psychology may not be applicable to constructing the same space in a virtual environment. Previous studies have shown consistent experimental results regarding emotional responses to color stimuli; however, no consistent outcomes have been reported regarding cognitive performance. This is because the effect of color impressions is thought to depend not only on the color itself but also on what is recalled. The results of this study suggest that red in a VR environment may be interpreted as a warning color, preventing people from losing focus.

The study compared two simulation environments for training of Swedish naval Command and Control teams by using indirect measures, including workload, combat readiness, and situation awareness. The literature explains simulation-based training as providing a safe avenue to practice relevant scenarios. Fidelity, the degree of realism in the simulation, and workload, the equilibrium between demands and assigned tasks, are crucial factors examined in this study of low- and high-fidelity naval simulations. This study was conducted to better understand the effects of various training methods. An experimental design with repeated measures was used with three consecutive escalating parts. The subjective, multidimensional assessment tool, NASA-Task Load Index was used to rate perceived workload. Combat readiness of the ship and mental demand yielded significant results. For combat readiness of the ship, there was a difference between the low and the high-fidelity setting, for the initial part of the scenario p = 0.037 and for the second part p = 0.028. Mental demand was experienced as higher in the low-fidelity setting, p = 0.036. Notably, the simulated internal battle training for onboard command teams in a low-fidelity setting was found to induce a level of stress comparable with that experienced in a high-fidelity setting. The results indicate that low-fidelity training results in a workload not distinguishable from high-fidelity training and has practical implications for increased use of low-fidelity training as part of (naval) command team training programmes.
