In this work, we propose a cognitive architecture that supports the autonomous discovery and learning of goals.

Moreover, we employ variational autoencoders and create projections of the latent spaces to dynamic neural fields through linear scaling. The aim of these projections is to investigate synaptic plasticity by varying a scaling factor. We demonstrate that a low scaling factor supports a random exploration strategy that produces more diverse actions with no tolerance regarding the discovery of similar goals. On the contrary, a sufficiently large scaling factor drives the exploration toward uncertainty reduction, focusing exploration as well as generating similar actions. In our case, we postulate that synaptic plasticity in working memory can be crucial for exploration and the learning of goals.</div></div>","PeriodicalId":55242,"journal":{"name":"Cognitive Systems Research","volume":"91 ","pages":"Article 101339"},"PeriodicalIF":2.1,"publicationDate":"2025-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143548011","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here we suggest that this problem may be overcome by taking inspiration from the brain where neurons operate as autonomous agents, each capable of adjusting its synaptic connections and internal states based on local information. Currently, typical artificial neurons are static nodes, which is in striking contrast to the rich, dynamic computations performed by biological neurons. In this review, we propose redesigning artificial neurons as self-regulating, agent-like units, making actions to maximize future energy/reward. Similarly, as single-celled organisms which can autonomously navigate in complex environments in search for food, neurons can also be viewed as autonomous decision-makers, seeking to maximize their own energy resources. Thus, neurons could be operating similarly like reinforcement learning (RL) agents, which make actions to obtain maximum future reward. Here first we review literature illustrating that biological neurons perform complex computations and employ local, predictive learning rules to anticipate future activity to maximize metabolic energy. Next, we provide examples of recent biologically inspired learning algorithms where artificial neurons are empowered with computational flexibility, similarly to autonomous agents. Networks with neurons using such local learning rules can in some examples outperform current AI algorithms. We also discuss how this can improve scalability of current multi-agent systems (MAS) and energy efficiency. Therefore, designing neurons as autonomous agents may provide an important step toward building human-like cognition.</div></div>","PeriodicalId":55242,"journal":{"name":"Cognitive Systems Research","volume":"90 ","pages":"Article 101338"},"PeriodicalIF":2.1,"publicationDate":"2025-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143479106","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Large language models (LLMs) can accelerate the development of comprehensive, extensive solutions that support mental health. However, the LLMs’ capability to generate and comprehend human-like conversations is one of the main challenges faced by psychiatric counselling. This work proposes a mental health counselling LLM-based conversational agent that relies on the integration of Retrieval Augmented Generation (RAG) and Reinforcement learning. RAG provides the proposed LLM-based conversational agent with contextually relevant and accurate responses through useful information extracted from a curated dataset of psychological questions and answers pooled from mental health forums. Reinforcement Learning Integrated reward Model trained with Human feedback has also been used in the proposed framework to ensure contractually of the responses generated with moral and human values. By setting up a reward mechanism that considers variables like user feedback and empathetic scores of responses, the proposed Conversational Agent learns to prioritize empathetic answers and the ones that are user preferable. With the utilization of reward-based training, the agent was able to show substantial improvements in response quality. Improved emotional alignment, steady training dynamics, decreased hallucination rates with responses having less distress and increased empathy values were the significant outcomes. The proposed methodology ensures that the conversational agent remains attentive to the emotional requirements of people seeking for mental health care and provide improved relevance and accuracy in its responses.</div></div>","PeriodicalId":55242,"journal":{"name":"Cognitive Systems Research","volume":"90 ","pages":"Article 101337"},"PeriodicalIF":2.1,"publicationDate":"2025-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143510955","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, it is still challenging to investigate the effects of urban landscapes in remote places. Nowadays, geotagged pictures share much information about urban landscapes worldwide. This work aimed to model the effect of geotagged pictures of urban landscapes on two mental states of attention and meditation using mobile EEG signals with multi-layer perceptron (MLP), random forest (RF), and support vector regression algorithms. Thirty-five picture features from 350 pictures of 39 Iran cities, and EEG signals of 32 healthy adult participants trained models. Cross-validation revealed that all models performed well with slight differences and had good generalizability. Meanwhile, the most accurate results were related to the prediction of the meditation state by RF with R² coefficient of 0.895, root mean square error of 0.149, and mean absolute error of 0.114. Correspondingly, 0.792, 0.178, and 0.14 were similar values for the prediction of attention state by MLP (the least accurate predictions). The Gini index recognized color histogram and HSV (hue, saturation, value) color space as the most important features in predictions. Generally, color features were more important than entity features, confirming the high impact of colors in landscapes. Although this research has some limitations, in line with previous works, we observed that each picture affected participants’ minds differently, existing particular elements in urban landscapes gained attention and meditation levels, and pictures of green space increased attention level more than meditation. Overall, the proposed approach may help to understand how urban landscapes affect citizens’ cognition even in unnoticed and remote places. However, using more conceptual picture features in modeling can improve the findings.</div></div>","PeriodicalId":55242,"journal":{"name":"Cognitive Systems Research","volume":"90 ","pages":"Article 101324"},"PeriodicalIF":2.1,"publicationDate":"2025-01-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143135648","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
