Rethinking lexical semantic fields: relevance and local holism

Abstract This paper aims to single out some pathologies of current lexical semantics, which suffers from both the trauma of immanence and the opposite anxiety of rooting all knowledge in the pre-semiotic dimension, or entrusting sense-making entirely to context. To untangle these pitfalls, the dialogue with a phenomenological cognitive semiotics may prove fertile to focus on the lexicon as a type of storage and a type of memory; that is, a type of accumulated and sedimented knowledge based on the dynamical re-pertinentization of invariants. In particular, the perspective developed by Sonesson shows striking coincidences with De Mauro’s semiotic semantics, which already provides a solid foundation for rethinking the notion of lexical field drawing on an “authentic” Humboldtian and Saussurean heritage. Therefore, I will briefly review some principles of lexical structural semantics, with the aim of showing how these notions, once emancipated from the Saussurean vulgata, can not only be compatible with a cognitive phenomenological approach, but also facilitate the rehabilitation of a theoretical apparatus still valuable for both (lexical) semantics and semiotics. Although focused on lexical fields, some of the issues addressed can be extended to language and languages, as well as to other types of semiotic systems, to shed light on controversial themes such as the embodiment of signs and the autonomy of linguistics and semantics.

A little imprecision goes a long way in launching memory development

AbstractFrom the earliest moments in their lives, infants begin to build memories about their past and accumulate knowledge about the world. In this article, we focus on the distinction between memory for specific events and memory for general information, and the ongoing debate about which type of memory provides the foundation for the development of the other. Some researchers argue that specific memory developmentally precedes general memory, whereas others support the opposite position. Our literature review suggests that the latter position is inconsistent with many empirical findings and theoretical principles of memory captured by computational models capable of accounting for these findings. We propose that just good enough mnemonic acuity could be a starting point for memory development, and that it can support both specific and generalized memories.

Predicting Cyclist Speed in Urban Contexts: A Neural Network Approach

Bicycle use has become more important today, but more information and planning models are needed to implement bike lanes that encourage cycling. This study aimed to develop a methodology to predict the speed a cyclist can reach in an urban environment and to provide information for planning cycling infrastructure. The methodology consisted of obtaining GPS data on longitude, latitude, elevation, and time from a smartphone of two groups of cyclists to calculate the speeds and slopes through a model based on a recurrent short-term memory (LSTM) type neural network. The model was trained on 70% of the dataset, with the remaining 30% used for validation and varying training epochs (100, 200, 300, and 600). The effectiveness of recurrent neural networks in predicting the speed of a cyclist in an urban environment is shown with determination coefficients from 0.77 to 0.96. Average cyclist speeds ranged from 6.1 to 20.62 km/h. This provides a new methodology that offers valuable information for various applications in urban transportation and bicycle line planning. A limitation can be the variability in GPS device accuracy, which could affect speed measurements and the generalizability of the findings.

Variance estimation using memory type estimators based on EWMA statistic for time scaled surveys in stratified sampling

In this article, we have proposed memory-type exponential and non-exponential estimators for population variance based on exponentially weighted moving average (EWMA) statistic in stratified sampling. We drive mathematical expressions for mean square errors of the proposed estimators using Taylor and exponential expansions. Our analysis demonstrates that the proposed memory-type estimators outperform the conventional estimators under stratification, particularly, when the information of previous sample is utilized. The performances of the proposed estimators are evaluated mathematically by deriving the conditions in which the memory-type estimators would perform better than their corresponding conventional estimators under stratification. Through an extensive simulation, we evaluated the performance of the proposed estimators across various population parameters, revealing their enhanced efficiency in time-scaled survey. Additionally, a real data application is also used to support the mathematical findings, confirming the practical utility of the proposed estimators. The results of numerical study underscore the importance of the use of previous sampled information which significantly improves the accuracy and reliability of the proposed estimator for variance estimation for time-scaled surveys.

Differential effects of negative valence and memory type on accuracy, confidence, and metacognitive efficiency

Emotion enhances the subjective experience of recollection. Previous research examined associations between memory accuracy and metamemory confidence judgments, but these studies have not quantified the relationship between accuracy and metacognitive confidence judgments. In this study we utilize signal detection theory frameworks to investigate how memory accuracy (measured by discrimination sensitivity) and the alignment between metamemory confidence judgments and memory accuracy (ie. metacognitive efficiency) varies for neutral and negative valence, as well as item and associative detail memory types. Our results indicate that valence and memory type have different effects on accuracy, confidence, and metacognitive efficiency. Negative valence was associated with enhanced accuracy for both items and associated details, but its relationship with response bias varied across memory types, with conservative recognition responses observed for items and liberal responses for associative details. We also observed a double dissociation between metamemory confidence judgements across valence and memory type with negative valence associated with increased confidence for item memory, but decreased confidence for associated details. Examining the association between memory accuracy and metamemory confidence revealed that metacognitive efficiency was greater for negatively valenced items compared to neutral, but this effect did not generalize to details associated with negatively valenced items. These findings advance our understanding of how arousing, negatively valenced information modulates memory and metacognition.

Optimal class of memory type imputation methods for time-based surveys using EWMA statistics

Time-based surveys often experience missing data due to several reasons, like non-response or data collection limitations. Imputation methods play an essential role in incorporating these missing values to secure the accuracy and reliability of the survey outcomes. This manuscript proposes some optimal class of memory type imputation methods for imputing missing data in time-based surveys by utilizing exponentially weighted moving average (EWMA) statistics. The insights into the optimal conditions for incorporating our proposed methods are provided. A comprehensive examination of the proposed method utilizing simulated and real-life datasets is conducted. Comparative analyses against the existing imputation methods exhibit the superior performance of our methods, particularly in the scenarios characterized by developing trends and dynamic response patterns. The outcomes highlight the effectiveness of utilizing EWMA statistics into memory type imputation methods, displaying their flexibility to changing survey dynamics.

Gaze and hand behaviors during haptic abilities testing-An update to multimedia learning theory.

The Cognitive Theory of Multimedia Learning (CTML) suggests humans learn through visual and auditory sensory channels. Haptics represent a third channel within CTML and a missing component for experiential learning. The objective was to measure visual and haptic behaviors during spatial tasks. The haptic abilities test (HAT) quantifies results in several realms, accuracy, time, and strategy. The HAT was completed under three sensory conditions using sight (S), haptics (H), and sight with haptics (SH). Subjects (n = 22, 13 females (F), 20-28 years) completed the MRT (10.6 ± 5.0, mean ± SD) and were classified as high or low spatial abilities scores with respect to mean MRT: high spatial abilities (HSA) (n = 12, 6F, MRT = 13.7 ± 3.0), and low spatial ability (LSA) groups (n = 10, 7F, MRT = 5.6 ± 2.0). Video recordings gaze and hand behaviors were compared between HSA and LSA groups across HAT conditions. The HSA group spent less time fixating on mirrored objects, an erroneous answer option, of HAT compared to the LSA group (11.0 ± 4.7 vs. 17.8 ± 7.3 s, p = 0.020) in S conditions. In haptic conditions, HSA utilized a hand-object interaction strategy characterized as palpation, significantly less than the LSA group (23.2 ± 16.0 vs. 43.1 ± 21.5 percent, p = 0.022). Before this study, it was unclear whether haptic sensory inputs appended to the mental schema models of the CTML. These data suggest that if spatial abilities are challenged, LSA persons both benefit and utilize strategies beyond the classic CTML framework by using their hands as a third input channel. This data suggest haptic behaviors offer a third type of sensory memory resulting in improved cognitive performance.

Remembering the life and dying days of a deceased close other: Memory recall and associations with loss context.

Grievers recall memories from both the life of the deceased and the dying days, but differences in recall across these memory types are not well-characterized. In this study, 100 bereaved German adults described up to ten important memories of a deceased close other (M = 7.86). Memories from the dying days were classified into: final memories, health transition events, last time events, and temporal markers. Among those who provided at least one dying days memory (73%), these memories were reported to be recalled privately and shared socially more often than memories from the deceased's life. Memories from the dying days were rated as less emotionally positive than those from the life, and contextual factors from the loss shaped memory recall frequency and emotional valence. Results underscore the need for appropriate end-of-life care to lay a foundation for adaptive remembering and suggest the relevance of dying days memories in therapeutic settings.

The role of the claustrum in the acquisition, consolidation and reconsolidation of memories in mice

The claustrum is a brain structure that remains shrouded in mystery due to the limited understanding of its cellular structure, neural pathways, functionality and physiological aspects. Significant research has unveiled connections spanning from the claustrum to the entire cortex as well as subcortical areas. This widespread connectivity has led to speculations of its role in integrating information from different brain regions, possibly contributing to processes such as attention, consciousness, learning and memory. Our working hypothesis posits that claustrum neural activity contributes to the acquisition, consolidation and reconsolidation of long-term memories in mice. We found evidence in CF-1 mice of a decline in behavioral performance in an inhibitory avoidance task due to intra-claustral administration of 2% lidocaine immediately after a training session or memory recall. Nevertheless, this does not seem to be the case for the acquisition or retrieval of this type of memory, although its neural activity is significantly increased after training, evaluated through c-Fos expression. Moreover, inhibition of the claustrum’s synaptic activity appears to impair the consolidation but not acquisition or retrieval of an unconditioned memory formed in a nose-poke habituation task.

The Social Memory of Sexual Violence: "You Touch One, You Touch Us All".

The social imaginary that legitimizes sexual violence is continuously reinforced by discourses that are deployed in the aftermath of physical attacks. These, in turn, nourish a specific type of collective memory from which clear social identities emerge. This article identifies the textual trajectories of social meanings associated with sexual violence and their discursive expressions in media, legal, and political discourses. The examples provided here are related to the Spanish "wolf pack case" and its social and political consequences. It concludes that the case not only generated a conceptual battle about violence but also a mnemonic dispute related to newly interpellated subjectivities.

Letters of Love: Engaging Memory Work in Qualitative Research

This article examines the role of memory and remembering in qualitative research, proposing a reflective practice where memories serve not only as a backdrop but as active participants in shaping inquiry. By revisiting and engaging in remembering, we, as qualitative inquirers, forge deeper connections with subjects, encompassing the human, the natural world, and the more-than-human. Drawing inspiration from Bridges-Rhoads et al.’s invitation to explore “readings that rock our world,” we extend this metaphor to memories that challenge and invigorate our academic and personal perspectives. We interrogate the types of memories that compel us to rethink our approaches to qualitative inquiry and recognize the often-excluded voices and narratives that emerge from personal and communal histories. Through a heartfelt compilation of love letters addressing people, objects, travels, and moments, this article champions the inclusion of marginal and overlooked memories within academic discourse. These narratives serve as points of departure for inquiry, challenging the boundaries of what is deemed academically valuable, legitimate, and legible. We extend this invitation to our readers to engage in a collective re-imagining and remembering of research practices, emphasizing the significance of memory work in shaping our way of being qualitative researchers and doing qualitative research.

Intertextual analysis as a tool for examining processes of memory transformation in literature: Types, figures, and functions

This article connects the theory of intertextuality and the concept of memory transformation. The transformations of mnemonic contents and the various forms of presentation that they have gone through before they crystallized in the texts are mostly invisible. In order to uncover these processes, Astrid Erll calls attention to the “travel” of memories. Based on intertextual theory, my analysis aims to distill categories for examining the transformative character of literary memory. For this purpose, I analyze the following three types of transformative memories— transgenerational postmemory, affiliative postmemory, and co-memoration—based on appropriate case studies. The categories of intertextual analysis that will be worked out in the article are as follows: The elements of intertextuality, the communicative acts between the previous and the manifest text that can be described as figures of intertextuality shaped by the specificity of each type of transformative memory; and the meta-content of intertextual transformation, that is, the characteristic purpose or quaestio that each memory transformation involves and that can be seen the function-aspect of intertextual communication.

Complex “simple nervous systems”

Terrestrial gastropods have evolved new structures in the nervous system compared to marine and aquatic snails in order to adapt to their new habitat. The behavior of these animals is qualitatively different from the behavior of aquatic gastropods, includes not only the possibility of active interaction with other animals, but also the demonstration of interest by active approach, avoidance or escape in certain cases. The “arrow of love” used in copulation is unique to Nature. Almost all types of associative memory can be formed in these animals, consolidation and reconsolidation of memory can be demonstrated, and mechanisms of memory maintenance and modification can be analyzed. At the level of functionally identified neurons and neural clusters, it is possible to study associative processes in vitro, a 3-neural model of associative longterm changes in synaptic efficiency has been developed.

A large language model-based agent for wayfinding: simulation of spatial perception and memory

ABSTRACT Using agents to simulate human wayfinding processes helps to understand human decision-making and spatial cognition. The performance of large language models (LLMs) in agent-based wayfinding is still unclear. To address this, this study harnessed the thinking and reasoning capabilities of LLMs by designing an agent wayfinding framework based on cellular automata. This framework provides environmental descriptions in text form to the LLMs, enabling them to perceive the wayfinding environment and navigate within it. We simulated different spatial memory conditions for the LLM, including three types of spatial memories and one condition with no spatial memory, to observe its wayfinding behavior in a real-world setting. Multiple experiments were designed to compare the wayfinding performance of the LLM under different spatial memories, and 32 human participants conducted the same wayfinding experiments for reference. The results indicate that the LLM autonomously explores the environment and displays spatial reasoning abilities similar to humans. Furthermore, the LLM can develop reasonable wayfinding strategies to complete the tasks. This framework allows agents with different spatial memories to accurately reach their destinations. This research provides new ideas for utilizing large language models to construct more intelligent, efficient, and flexible wayfinding agents, which can help advance the application of agent technology in fields such as navigation and robotics.

Basolateral amygdala inputs to the nucleus accumbens shell modulate the consolidation of cued-response and inhibitory avoidance learning

The basolateral amygdala (BLA) modulates different types of memory consolidation via distinct projections to downstream brain regions in multiple memory systems. Prior studies indicate that the BLA projects to the nucleus accumbens shell (NAshell) and that these regions interact to influence some types of behavior. Moreover, previous pharmacological work suggests the BLA and NAshell interact to influence memory. However, the precise role of the BLA-NAshell pathway has never been directly investigated in the consolidation of different types of memory including cued-response, spatial, or inhibitory avoidance (IA) learning. To address this, male and female Sprague-Dawley rats received optogenetic manipulations of the BLA or BLA-NAshell pathway immediately following training in different learning tasks. An initial experiment found that optogenetically inhibiting the BLA itself immediately after training impaired cued-response retention in a Barnes maze task in males and females, confirming earlier pharmacological work in males alone. Subsequent experiments found that BLA-NAshell pathway inhibition impaired retention of cued-response and IA learning but had no effect on retention of spatial learning. However, the present work did not observe any effects of pathway stimulation immediately after cued-response or IA learning. Together, the present findings suggest the BLA modulates the consolidation of cued-response and IA, but not spatial, memory consolidation via NAshell projections.

The purpose of metaphysics: Apology of excess

AbstractThis article consistently elaborates the extra‐contextual nature of metaphysical knowledge. Metaphysicsis seen as a semantic construction of culture that produces a certain type of thinking, memory, and identification: that is, subjectivity, and sociality as an ethical and axiological model of interaction with the world and the Other. The paper argues that metaphysics is a kind of orientation in space and that culture is a semiotic way of world orientation, or collection of spaces into an intelligible structure, a specific characteristic of human existence in the universe. Indeed, metaphysics through the space of culture allows one to experience the universe empirically as unity, to assume the presence of meaning. Based on the analysis, the paper summarizes the definition of the phenomenon of culture as a specifically human way of mastering space and controlling time, consciousness as a topology of reflective practices, and virtual reality technology as a space of pure metaphysics.

Age-related decline in source and associative memory.

This review explores the multifaceted nature of age-related decline in source memory and associative memory. The review highlights the potential effects of age-related decline in these types of memory. By integrating insights from behavioral, cognitive, and neuroscientific research, it examines how encoding, retrieval, and neural mechanisms influence this decline. Understanding these processes is critical to alleviate memory decline in older adults. Directing attention to source information during encoding, employing unitization techniques to strengthen memory associations, and utilizing metacognitive strategies to focus on relevant details show promise in enhancing memory retrieval for older adults. However, the review acknowledges limitations in processing resources and executive function, necessitating a nuanced approach to the complexities of age-related decline. In conclusion, this review underscores the importance of understanding the complexities of age-related source and associative memory decline and the potential benefits of specific cognitive strategies. It emphasizes the need for continued research on age-related memory function to improve the quality of life for aging populations.

Evaluation of recognition memory through oculomotorius behavior in Alzheimer disease.

INTRODUCTION: The study of ocular movements in patients with Alzheimer disease is an useful tool to evaluate recognition memory. METHODS: assessment of this specific type of explicit memory in 15 individuals diagnosed with Alzheimer disease and 15 controls. The parameters of ocular fixation were examined using the Eye-Tracking Tobii Tx300 through Pair-wised ranking with the paradigm novel object recognition. RESULTS: People with Alzheimer disease present difficulties in the recognition of previously presented stimulus when the latency of presentation of the familiarization and the test period is longer than two minutes. DISCUSSION: The analysis of oculomotorius behavior can simplify the evaluation of recognition memory without appealing to verbal report and the visual paired comparison task. This contributes to the comprehension of the relationship among spatial attention, working memory and episodic memory.

Face naming and recollection represent key memory deficits in developmental prosopagnosia

Previous studies have found that face perception deficits do not fully account for the severity of face recognition deficits in developmental prosopagnosia (DP). Researchers have begun identifying deficient memory mechanisms such as impaired face recollection, but these findings require replication, and further characterization of additional memory deficits is necessary. Our goals were to replicate prior findings of face recollection impairment in DP and extend these findings to assess different types of face associative memory. We had 69 DPs and 99 controls perform a face perception battery as well as three face memory tasks: 1) Old/New task with confidence ratings to calculate recollection and familiarity using ROC analysis, 2) Face/Scene task to examine remember-know judgments and contextual memory for faces, and 3) Face-Name/Occupation task to assess the ability to learn semantic associations with faces. Compared to controls, DPs showed poorer recollection and familiarity across both Old/New and Face/Scene tasks as well as reduced scene accuracy for correct faces. Of these differences, only Old/New recollection remained significant after controlling for group differences in face perception abilities. In the Face-Name/Occupation task, after controlling for face perception, DPs showed poorer recall of names than controls but performed similarly in recalling occupations. Finally, we found that DPs with major, mild, and no face perception deficits showed consistent impairments in Old/New recollection and face-naming, and larger perceptual deficits were associated with larger memory deficits. Together, these results provide several mechanistic insights into the nature of memory deficits in DPs and have diagnostic and treatment implications.
