Social isolation (SI) is a modifiable factor, thought to impact cognitive resilience, with the potential to impact cognition up to ADRD diagnosis and throughout disease duration. MMSE and/or MoCA cognitive function measurements, demographic (including marital and accommodation status SI proxies) and diagnosis data were extracted, using natural language processing, from electronic health records from Oxford NHS patients aged 50+ years. Longitudinal multilevel models were used to predict cognition as a function of the interaction between diagnosis duration and SI proxies, controlling for age and sex. Using MoCA, ‘lifelong single’ marital status significantly predicted reduced cognition intercept scores (𝛽 = -2.84, SE = 0.82, t = -3.52, p &lt; 0.001) and ‘no fixed abode’ accommodation status significantly predicted steeper slopes for cognition (𝛽 = -3.26, SE = 1.63, t = -2.00, p = 0.046). SI proxies should be considered with regard to ADRD patient cognitive change and care.

The 46th Annual Meeting of the Cognitive Science Society presents the latest research across cognitive science and highlights the theme of Cognition in Context.

Searching through memory is mediated by complex interactions between the underlying mental lexicon and the processes that operate on this lexicon. However, these interactions are difficult to study due to the effortless manner in which neurotypical individuals perform cognitive tasks. In this work, we examine these interactions within a sample of prelingually deaf individuals with cochlear implants who were administered the verbal fluency task. Specifically, we test how two potential candidates for mental lexicons constructed from textual (word2vec) versus speech-based (speech2vec) information, when combined with different process models of memory search account for search behavior within the verbal fluency task for CIs and normal hearing individuals. Our findings show that semantic and phonological information jointly influences search behavior at the structural and process level and highlight the delicate balance of different lexical sources that produces successful search outcomes.

Structure and process-level lexical interactions in memory search: A case study of individuals with cochlear implants and normal hearing

Having a correct mental model of a technical system facilitates interaction and problem solving. To assess such mental models of system functioning, appropriate methods are needed. We tested whether concept mapping with a focus on functional means-ends relations leads to valid representations of participants’ mental models of system functioning. Automotive and utility vehicle apprentices constructed concept maps of two simple, everyday systems (bike, traffic) and one complex, domain-specific system (fuel temperature control). However, only one group of participants had previously covered the complex system in class. Aspects of participants’ concept maps regarding content (correct functional propositions) and structure (intersection over union) were assessed and related to a reference map. Results indicated that concept maps for the complex system validly represented mental model content, but not mental model structure. We argue that the applied functional structure might need to be adapted to participants’ domain and typical tasks.

Validity of Concept Mapping for Assessing Mental Models of System Functioning

Evolutionary accounts suggest that individuals readily categorize other individuals into an ingroup and an outgroup, and consequently display a strong preference for positive behaviors towards the members of the ingroup relative to the outgroup. In the current study, we tested whether the robust ingroup bias could be modulated at the perceptual level based upon differential contextual information about group characteristics and group relations. Across the four experiments, participants performed a social associative matching task within the minimal group framework. We found that while the ingroup bias is certainly robust, it gets attenuated if the outgroup is portrayed positively and also when the ingroup is depicted negatively. This may have consequences for researchers studying intergroup conflict and consequent policy making.

Holier-Than-Thou: Can Contextual Information About Minimal Groups Modulate the Robust Ingroup Bias Effect?

The Locally Bayesian Learning (LBL) approach bridges the gap between optimal Bayesian learning and suboptimal performance that arises from human behavior. Although this learning model has considerable potential, it has been underdeveloped and has remained in original form for several decades. In this paper, we extend the original LBL model to an exemplar approach, which we refer to as the exemplar-LBL model. Two notable features of this extension are that (a) the model can take continuous features as inputs and (b) can conduct exemplar-based categorization. We report various simulations, which show that the model can generate various important predictions about category learning. Moreover, we introduce the extra-learning hypothesis, which can account for how classification and observation training can produce differential learning. Our results showcase scenarios under which classification training is superior to observation training and other instances in which the opposite holds.

Extending the Locally Bayesian Learning Model to Exemplar-Based Categorization with Continuous Features

Category learning, a fundamental cognitive ability, is significantly influenced by variability. In this research, we propose a model describing how people adjust information search in self-regulated category learning to the level of category variability. Participants in the self-regulated category learning task sampled from two categories until they felt confident in categorizing novel objects. Our model assumes an influence of the variability of the focal and counter category on sampling by considering a within-category and between-category processes. In both processes, variability is quantified using an information-theoretic measure. Within this model, we test if a between-category process can be better conceptualized as either a contrasting or an assimilation process.
The comparison of both processes support a between-category assimilation process, where the sample size adjusts to the counter category's variability. This novel focus sheds light on between-category dynamics, providing valuable insights into the mechanisms of category learning.

Category Learning in Context: Modelling an Assimilation Process in Self-regulated Category Learning

We examined whether selective attention, which is mainly theorized as the ability to focus on the category-relevant dimension, is a sole construct in understanding category learning. As the attention literature dissociates selective attention into focusing and filtering, we argue that filtering is another component that should be considered to fully understanding category learning. In the study, we provide an experimental paradigm that can dissociate filtering from focusing. By utilizing the paradigm along with collecting individual attention control measures, we show that filtering is related to the ability to inhibit irrelevant information. We also present that the current computational models that incorporate selective attention only as an ability to focus can not explain the results from the current study.

Is focusing enough in category learning?

When people solve problems, they may try multiple invalid solutions before finally having an insight about the correct solution. Insight problem-solving is an example of the flexibility of the human mind which remains unmatched by machines. In this paper, we present a novel experimental paradigm for studying insight problem-solving behavior in a physical reasoning domain. Using this paradigm, we seek to quantify precisely what it means to have an insight during physical problem-solving and identify behavioral traces that predict subjective insight ratings collected from human participants. The project provides the first steps towards a computationally informed theory of insight problems solving.

Predicting Insight during Physical Reasoning

Social norms as an interactive process: An agent-based cognitive modelling study

When people make decisions, these often do not stand alone but are made in a sequence of decisions. For instance, a doctor will first decide on a patient's treatment and then about the duration of the treatment, such that later decisions frequently depend on the outcome of the first decision. While there is research on how humans discover inter-relations between sequentially presented information (e.g., grammar), little is known about learning complex inter-category relations in decision sequences. Hence, we present an experiment in which we embedded an Exclusive-Or (Type-II) structure, as known in category learning, in a sequence of three categorization tasks. In a Type-II condition, task 1 and 2 outcomes predicted those of task 3. We hypothesized that embedded structure would facilitate learning and generalization compared to sequence without regularity. Instead, the evidence favored the Null hypothesis in both cases, contrasting to the findings in the visual categorization domain.

XOR in Order: Category Learning of Exclusive-Or in a Temporal Sequence

In decision-making, the Levy flights model (LFM), an extension of the diffusion decision model, adopts a heavy-tailed distribution with the pivotal 'alpha' parameter controlling the shape of the tail. This study critically examines the theoretical foundations of alpha, emphasizing that its test-retest reliability is essential to classify it as a cognitive style measure. Our analysis confirms the alpha parameter's test-retest reliability across various occasions and tasks, supporting its role as a trait-like characteristic. The study also explores LFM parameter interrelations, despite low correlation among the other parameters (so representing distinct aspects of data), there is a pattern of strong correlation between alpha and threshold. Investigating the practice effect, our analyses indicate a consistent decrease in non-decision time, threshold, and often alpha across sessions, alongside the drift-rate increase. We also employ Bayesflow for parameter estimation, evaluating its precision with different trial counts. These findings provide valuable guidelines for future LFM research.
