This short research article interrogates the rise of digital platforms that enable ‘synthetic afterlives’, with a focus on how deathbots – AI-driven avatar interactions grounded in personal data and recordings – reshape memory practices. Drawing on socio-technical walkthroughs of four platforms – Almaya, HereAfter, Séance AI, and You, Only Virtual – we analyse how they frame, archive, and algorithmically regenerate memories. Our findings reveal a central tension: between preserving the past as a fixed archive and continually reanimating it through generative AI. Our walkthroughs demonstrate how these services commodify remembrance, reducing memory to consumer-driven interactions designed for affective engagement while obscuring the ethical, epistemological and emotional complexities of digital commemoration. In doing so, they enact reductive forms of memory that are embedded within platform economies and algorithmic imaginaries.

The worldwide increase in life expectancy has resulted in a significant aging of the population. The physiological and functional changes that result from the aging process, changes in sleep patterns, and the prevalence of chronic diseases affect the health and well-being of individuals aged over 60.
Abstract Images generated using artificial intelligence (AI) have become increasingly realistic, sparking discussions and fears about an impending “infodemic” where we can no longer trust what we see on the internet. In this preregistered study, we examine whether providing specific media literacy tips about how to spot AI-generated images can reduce susceptibility to AI-generated visual misinformation (AIVM). Participants were randomly assigned to one of three conditions, reading specific media literacy tips, general media literacy tips, or no media literacy tips (control). The general tips provided tips on how to spot misinformation, while the specific tips provided more detailed tips for how to detect AIVM. Results showed that specific tips increased headline discernment between true and false information more than general tips. Both media literacy interventions reduced belief in AIVM compared to control, but specific tips reduced belief in AIVM more than general tips. Finally, both specific and general tips also reduced belief in real headlines compared to control, with no difference between them. In an information environment that sees increasing prevalence of AIVM, it may be worth being specific about how to detect misinformation online rather than only providing general information.
Scalar inference (SI), e.g., utterances containing some being enriched to mean some but not all, is a central topic in semantics and pragmatics. Of recent interest in the experimental literature is scalar diversity: different lexical scales differ in their likelihood of leading to SI. Studies of scalar diversity have almost exclusively relied on the so-called inference task. In this article, we highlight two shortcomings of the inference task: it biases participants by providing them with the stronger alternative, and it obscures pragmatic inferences other than SI. We offer as an alternative a degree estimate task to investigate utterances containing scalar terms. We validate the degree estimate task, i.a., by successfully replicating a previous finding about scalar diversity: that the distinctness of scalar terms (some versus all) is a significant predictor of it. We then use degree estimates to reassess previous inference task-based findings. Our results show that biasing discourse contexts lead to lower degree estimates (i.e., more strengthened meanings) than a manipulation with only, which contrasts with prior literature’s findings. The article concludes that the inference and degree estimate tasks both have advantages: the former offers a straightforward definition of SI calculation, while the latter avoids explicitly mentioning a negated stronger alternative.

Background: Cognitive skills are important in athletics, especially in football, because quick thinking, teamwork and fast reaction times are key. Concussions have different results for female athletes than for males which can result in changes in both cognitive and physical performance. Yet, there is not much information available on cognition and performance link in female football players who have had concussions.
Objective: To determine the association between cognitive function and physical performance in female football players with a history of concussion.
Methodology: This cross-sectional study included n=84 female football players aged 14–25 years. Verbal Cognition Test (VCT) for executive function, Delayed Word Recall (DWR) for working memory, Digit Backward (DB) for memory and Attention and Month in Reverse Order (MRO) for executive function were used to test cognitive function. Physical performance assessments included the Vertical Jump, Run Three, 505 Agility and 3-HOP Tests (both right and left legs). The study used a multiple regression analysis while controlling for age, BMI, amount and timing of play, number of headings during games, collisions and temporary loss of consciousness.
Result: The results show that having lesser VCT and MRO leads to poorer results in the 3-HOP Right Leg test (p<0.05). Practicing high-heading skills allowed athletes to complete Run Three faster (p=0.043). Nearly significant findings indicated that concussion history did play a moderating role in the results (p=0.079). For Vertical Jump, 505 Agility and 3-HOP Left Leg tests, no significant relationships were discovered.
Conclusion: The performance of female football players in lower-body power and agility is affected by cognitive functions, especially by verbal skills and reaction time.

Abstract Some animals seek information to solve problems when they do not know the answer. Information-seeking behavior has become a key focus in studies of animal metacognition, providing insights into how animals monitor their own knowledge states. This behavior is thought to be a form of metacognitive control. Nevertheless, research on such metacognitive control has been biased toward specific taxa, such as primates, and has not been conducted in rodents, which are the most common experimental animals. This study examined whether mice exhibit information-seeking behavior during two visual discrimination tasks and what factors influence this behavior. We trained mice to discriminate between stimuli differing in luminance or orientation, with more minor differences increasing task difficulty. An information-seeking option was introduced during these tasks, allowing mice to eliminate distractor stimuli and ensure a correct response. The results indicated that mice sought information more frequently during difficult discriminations than easier ones. However, subsequent generalization tests revealed that the mice relied on environmental cues to utilize the information-seeking option. These findings suggest that information-seeking behavior in mice may not solely reflect metacognitive processes, and further investigation is needed to explore alternative explanations.
Little is known about the brain correlates of anosognosia or unawareness of disease in Parkinson’s Disease (PD) and Huntington’s Disease (HD). The presence of unawareness or impaired self-awareness (ISA) of illness has profound implications for patients and their caregivers; therefore, studying awareness and its brain correlates should be considered a key step towards developing effective recognition and management of this symptom as it offers a window into the mechanism of self-awareness and consciousness as critical components of the human cognition. We reviewed research studies adopting MRI or other in vivo neuroimaging technique to assess brain structural and/or functional correlates of unawareness in PD and HD across different cognitive and motor domains. Studies adopting task or resting-state functional magnetic resonance imaging, and/or 18-F fluorodeoxyglucose positron emission tomography brain imaging and/or magnetic resonance imaging structural measures were considered. Only six studies investigating neuroimaging features of unawareness in PD and two in HD were identified; there was great heterogeneity in the clinical characteristics of the study participants, domain of unawareness investigated, method of unawareness assessment, and neuroimaging technique used. Nevertheless, some data converge in identifying regions of the salience and frontoparietal networks to be associated with unawareness in PD patients. In HD, the few data are affected by the variability in the severity of motor symptoms. Further studies are needed to better understand the mechanisms and brain correlates of unawareness in PD and HD; in addition, the use of dopaminergic medications should be carefully considered.

Several studies have suggested that time monitoring is important for appropriate time-based prospective memory (TBPM). However, it is still unknown if people actively use internal timing processes to monitor the approaching target time, and whether they do so by tracking the duration between clock digits, or by counting and matching the numerical progression of clock ticks' digits with the target time. Therefore, in the present study, we investigated whether a manipulation of the external time affected time monitoring and TBPM performance. In two experiments, participants performed two identical TBPM tasks: a first TBPM block with no clock-speed manipulation followed by a second TBPM block, where the clock-speed was manipulated as faster or slower (experimental conditions) or normal (control condition). The results showed that only participants in the slower clock condition increased time monitoring in the second compared to the first TBPM block (d = 0.42 and 1.70); moreover, particularly in Experiment 2, participants in the faster clock condition checked the clock significantly less frequently than participants in the slower clock (d = -1.70) and in the control condition (d = -0.98), but only during the 4th minute. No effect was found for TBPM performance. Overall, results suggested that people tracked the target time by counting and matching the numerical progression of clock ticks' digits with the target time. The findings are discussed considering the most recent theoretical advancements about the relationship between time perception and TBPM.

According to the ideomotor principle, repeated experience with an action and its perceivable consequences (effects) establish action-effect associations. Research on verbal instructions indicates that such associations are also acquired from verbal information. In the present experiment (N = 651), first, we aimed to replicate unintentional response-priming effects from verbal action-effect instructions (direct replication; Condition 1). Second, we investigated the involvement of perceptual processes in the verbally induced response-priming effect by perceptually presenting (Condition 1) versus not presenting (Condition 2) the color that was subsequently named as an effect in the instructions. Third, we tested a saliency-based explanation of the verbally induced response-priming effect by highlighting all components (action and effect) without an association between them (Condition 3). Overall, we found the predicted response-priming effect following verbal action-effect instructions (overall conditions and in the replication Condition 1). Condition 2, which did not include perceptual information in the instructions, still showed a significant response-priming effect but was descriptively weaker compared to the effect of the replication Condition 1. Condition 3, which merely highlighted the action and effect component without endorsing an association, did not show a significant effect. In sum, our study provides further solid evidence that verbal instructions lead to unintentional response-priming effects. Other conclusions must be considered preliminary: The between-condition comparisons were descriptively in the predicted direction—perceptual aspects are relevant, and a saliency-based account can be excluded—but the differences in accuracy between conditions were not statistically significant.
Based on a material view and reductionism, science has achieved great success. These cognitive paradigms treat the external as an objective existence and ignore internal consciousness. However, this cognitive paradigm, which we take for granted, has also led to some dilemmas related to consciousness in biology and physics. Together, these phenomena reveal the interaction and inseparable side of matter and consciousness (or body and mind) rather than the absolute opposition. However, a material view that describes matter and consciousness in opposition cannot explain the underlying principle, which causes a gap in interpretation. For example, consciousness is believed to be the key to influencing wave function collapse (reality), but there is a lack of a scientific model to study how this happens. In this study, we reveal that the theory of scientific cognition exhibits a paradigm shift in terms of perception. This tendency implies that reconciling the relationship between matter and consciousness requires an abstract theoretical model that is not based on physical forms. We propose that the holistic cognitive paradigm offers a potential solution to reconcile the dilemmas and can be scientifically proven. In contrast to the material view, the holistic cognitive paradigm is based on the objective contradictory nature of perception rather than the external physical characteristics. This cognitive paradigm relies on perception and experience (not observation) and summarizes all existence into two abstract contradictory perceptual states (Yin-Yang). Matter and consciousness can be seen as two different states of perception, unified in perception rather than in opposition. This abstract perspective offers a distinction from the material view, which is also the key to falsification, and the occurrence of an event is inseparable from the irrational state of the observer’s conscious perception. Alternatively, from the material view, the event is random and has nothing to do with perception. We hope that this study can provide some new enlightenment for the scientific coordination of the opposing relationship between matter and consciousness.
Abstract Spatial skills are an important component of success in science, technology, engineering, and math (STEM) fields. A majority of what we know about spatial skills today is a result of more than 100 years of research focused on understanding and identifying the kinds of skills that make up this skill set. Over the last two decades, the field has recognized that, unlike the spatial skills measured by psychometric tests developed by psychology researchers, the spatial problems faced by STEM experts vary widely and are multifaceted. Thus, many psychological researchers have embraced an interdisciplinary approach to studying spatial thinking with the aim of understanding the nature of this skill set as it occurs within STEM disciplines. In a parallel effort, discipline-based education researchers specializing in STEM domains have focused much of their research on understanding how to bolster students’ skills in completing domain-specific spatial tasks. In this paper, we discuss four lessons learned from these two programs of research to enhance the field’s understanding of spatial thinking in STEM domains. We demonstrate each contribution by aligning findings from research on three distinct STEM disciplines: structural geology, surgery, and organic chemistry. Lastly, we discuss the potential implications of these contributions to STEM education.
This paper presents the features of the dynamic frame verbalization as one of the ways of ordering scientific knowledge. The scientific discourse or text under study are considered as areas in which the terms are directly included in real professional communication. German language fragments describing the situation of cognition within the framework of a certain professional discourse and defining the specificity of a scientific text as its resulting form are used as the research material. The terms “static” and “dynamic frame” are used to differentiate the knowledge possessed by the subject in the construction of a sentence, and the knowledge fixed by a person in a particular speech act. With the help of frame analysis, the obligatory and conditioned by the situation slots of the dynamic frame objectified in the language are revealed. The relationship between the static and dynamic frame is considered in the aspect of speech-thinking processes. The authors describe the characteristics of filling the slots of the frame-prototype which covers the necessity of defining some concepts and of folding the frame-example reflecting the generalization aspect. The study allows us to make a conclusion about the existence of a categorical grid in human consciousness for organizing scientific information both at the level of consciousness and at the level of the text. This regularity is reached be finding the meaning dominants and defining the main features with their following matching with the categorical net nodes. The presence of repetitive semantic nodes in language fragments indicates the unity of the information processing principles, according to which scientific knowledge acquires a unified form, which contributes to people interaction within the marked categories.

Prior research has yielded mixed findings on whether learners’ certainty reflects veridical probabilities from observed evidence. We compared predictions from an idealized model of learning to humans’ subjective reports of certainty during a Boolean concept-learning task in order to examine subjective certainty over the course of abstract, logical concept learning. Our analysis evaluated theoretically motivated potential predictors of certainty to determine how well each predicted participants’ subjective reports of certainty. Regression analyses that controlled for individual differences demonstrated that despite learning curves tracking the ideal learning models, reported certainty was best explained by performance rather than measures derived from a learning model. In particular, participants’ confidence was driven primarily by how well they observed themselves doing, not by idealized statistical inferences made from the data they observed.
