Many infant experiences are both visual and auditory in nature, but what is the role of auditory cues in visual attention? Using a Dynamic Field model of infant visual attention, we generated simulations of infant looking behaviour in both a tone and no tone version of the Infant Orienting With Attention (IOWA) task. The DF model predicted a significant difference in reaction times and accuracy between the tone and no tone groups with the tone group faster and less accurate. To test this, we ran the IOWA task with 70 infants between 4 and 10 months of age randomly assigned to either a tone or no tone condition. There were no significant between-group differences. We explore these empirical findings using the dynamic field model, extending the model in two directions. First, we utilise Tensorflow tools to optimise the model parameters, and second, we fit the model parameters to individuals.

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

From career planning to disaster preparedness to public policy, people plan all the time in complex environments. Yet, it is not known what cognitive abilities are critical for such planning. To explore this, we conducted an online experiment in which 476 participants each completed nine cognitive tasks: Raven’s Matrices, Mental Rotation, Corsi Block Task, Change-Detection Task, Pattern Recognition Task, Wisconsin Card Sorting Task, a complex two-player game called Four-in-a-Row, and two simpler planning tasks. We found moderate correlations across most metrics, aligning with existing literature on cognitive interconnectivity. Notably, performance in the Four-in-a-Row game correlated with all other tasks, suggesting that planning ability in complex tasks (which require multiple steps ahead) is correlated with that in simpler tasks, suggesting a shared computational substrate. Moreover, we identified distinct latent factors for mental rotation and planning tasks, suggesting that tree search in planning tasks and mental rotation tasks require distinct simulation abilities. These findings enhance our understanding of the cognitive processes involved in complex planning.

The Cognitive Components of Complex Planning

Environmental stressors present negative consequences for cognitive development. However, their impact on relevant neurocognitive processes, particularly in underrepresented samples, is less clear. The current project aims to examine how adverse experiences influence efficiency of evidence accumulation and neural connectivity in adolescents. The study included 199 adolescents from the Future of Families and Child Wellbeing Study, a population-based longitudinal cohort study with substantial representation of youths from disadvantaged backgrounds. Participants completed an emotional-faces, gender-identification task while undergoing functional MRI. Reaction times (RT) and responses were recorded and fitted with a drift-diffusion model. Parameters were estimated using the Dynamic Model of Choice software, which provides a better characterization of the underlying cognitive mechanisms compared with using RTs or battery tasks. Analyses investigating the impact of adverse experiences to drift rate and functional connectivity are underway. Results from this study will provide a better understanding of adversity on neurocognitive mechanisms in adolescents.

Understanding the impact of early adverse experiences on computational models of neurocognitive processes in adolescents

Humans can flexibly pursue goal-oriented behavior in the face of changes in the environment. Cognitive control refers to this set of processes allowing such adjustments, and is thought to rely on neural oscillations in the theta band (4-8Hz). First, theta amplitude increases when control is needed, and second, shifts of peak frequency in the theta band have been suggested to reliably balance task representation and gating of task-relevant sensory and action information. However, it remains unknown how these two characteristics of the control signal interact and how optimal configuration for task performance is achieved. To tackle this question, we developed a computational model that relies on reinforcement learning principles to find optimal control settings for task performance. Our simulations show that these different oscillatory characteristics play distinct roles in the flexible adjustment to task demands. This work opens new avenues for research on the mechanisms allowing cognitive flexibility.

Flexible adjustment to task demands through learning of optimal oscillatory characteristics

We report a large study (n=120) investigating the effects of tDCS at Fp3 on the FIE. We used a double-blind design with subjects randomly assigned to one of the three tDCS groups and then engaged with a recognition task involving upright and inverted faces. Group 1 (control), subjects first received sham-tDCS in the study phase (learning) followed by sham-tDCS in the recognition phase; Group 2, subjects received anodal-tDCS in the study phase followed by sham-tDCS in the recognition phase; Group 3, subjects received anodal-tDCS in the study phase followed by cathodal-tDCS in the recognition phase. Group 2’s results confirmed that anodal-tDCS reduces the FIE vs. sham (Group 1) by disrupting performance for upright faces. Group 3’s results revealed that cathodal-tDCS applied after anodal, increased the FIE vs. Group 2, bringing it back to control, by enhancing performance for upright faces. These results reveal that the negative effects of anodal-tDCS on the FIE can be reversed by cathodal-tDCS.

Understanding and quantifying listening effort (LE) is important to a better understanding of speech perception in acoustically challenging environments. EEG alpha power has shown promise as a measure of LE, but relationships between acoustic challenge and alpha have been inconsistent in prior work. We test whether these mixed findings are attributed to differences in alpha power measurement across studies. We compared traditional bandwidth measurement of alpha power to an algorithmic spectral parameterization (SP) approach which separates alpha from background changes in broadband aperiodic activity. Whereas the traditional approach yielded no significant difference in alpha between speech in quiet versus in background noise, the SP approach, which accounts for flattening of the broadband slope in noise, yielded a significant increase in alpha power to speech in noise. These results highlight the importance of accounting for aperiodic brain activity when considering oscillatory EEG markers of cognitive demand in speech perception.

A better alpha - Incorporating spectral parameterization to improve measurement of listening effort

Our interaction with others largely hinges on how we semantically organize the social world. The organization of such conceptual information is not static– as we age, our experiences and ever-changing anatomy alter how we represent and arrange semantic information. How does semantic distance between concepts affect this organization, particularly for those with pathological deficits semantic knowledge? Using triadic judgment responses collected from healthy participants, we compute an ordinal similarity embedding for a set of social words and images that vary in the dimensions of age and gender. We compare semantic distances between items in the space to patterns of error in a word-picture matching task performed by patients with semantic dementia (SD). Error patterns reveal that SD patients retain gender information more robustly than age information, and that age-related errors are a function of linear distance in age from a concept word. The distances between probed and exemplar items in the resulting conceptual map reflect error patterns in SD patient responses such that items semantically closer to a probed concept– in gender category or in linear age–are more likely to be erroneously chosen by patients in a word-picture matching task. To our knowledge, this is the first triplet embedding work to embed representations of words and images in a unified space, and to use this space to explain patterns of behavior in patients with impaired social semantic cognition.

Semantic distance organizes social knowledge: Insights from semantic dementia and cross-modal conceptual space

Numerical and spatial skills are highly interrelated, and both contribute to mathematical cognition (Dehaene & Brannon, 2001). Spatial-numerical associations are frequently examined using number line estimation (NLE); however, there is considerable debate about the relative contributions of number-specific and domain-general (i.e., working memory) processing involved in this task (Simms et al., 2016). Here, we used functional neuroimaging to examine the processes supporting NLE in adults (n = 32). Participants completed an in-scanner NLE task and category localizer. We found that within the Number ROI from the localizer (Number > Faces + Words), neural activity during the in-scanner NLE task differentially predicted out-of-scanner behavioral measures. Specifically, activity in the left intraparietal sulcus (IPS) predicted spatial working memory, whereas activity in the right IPS predicted performance on an out-of-scanner NLE task. These findings suggest that performance during NLE relies on both spatial-numerical and domain-general capacities, but that these capacities are supported by separate neural regions.

Neural lateralization during number line estimation differentially predicts numerical and spatial capacity

Research on infants' observational behavior has predominantly focused on retrospective information gain, leaving the role of prospective evaluation of information gain unclear. We examined 12-month-olds' use of information sources in an eye-tracking study, where participants could use their gaze to 'shake' two out of three boxes to locate a hidden character through auditory cues. Across two pre-registered experiments, we manipulated the probability distributions for character locations to assess forward-looking exploratory strategies. Findings from Experiment 1 with a uniform distribution suggest that while infants learned task contingencies, their choices did not align with maximizing expected information gain, leaning instead towards confirmatory hypothesis testing. Experiment 2 employs a non-uniform probability distribution for character locations to rule out alternative explanations of Experiment 1. In this setup, one box pair provides more information gain, while the other provides confirmatory evidence. Data collection is in progress, results will be presented at the conference.

Infants’ evaluation of expected information gain in a gaze-contingent paradigm

Does language help make sense of the visual world? How important is it to actually see the world, rather than having it described with words? These basic questions about the nature of intelligence have been difficult to answer because we only had one example of an intelligent system -- humans -- and limited access to cases that isolated language or vision. However, the development of sophisticated Vision-Language Models (VLMs) by artificial intelligence researchers offers us new opportunities to explore the contributions that language and vision make to learning about the world. We ablate components of the cognitive architecture of these models to identify their contributions to learning new tasks from limited data. We find that a fully-equipped language model recovers a majority of a VLM's performance, despite its lack of visual input, and that language seems to allow this by providing access to prior knowledge and reasoning.

Analyzing the Roles of Language and Vision in Learning from Limited Data

One of the many tasks facing the typically-developing child language learner is discovering a small inventory of unique sounds (phonemes) that comprise the words in their language. Here we investigate whether multimodal information --- specifically audio coupled with video frames of speakers' faces --- benefits a model of phonemic category learning. We introduce a method for creating a high-quality synthetic videos of speakers' faces for an existing audio corpus. Our learning model, when both trained and tested on audiovisual inputs, achieves up to a 8.1% relative improvement on a phoneme discrimination battery compared to a model trained and tested on audio-only input. It also outperforms the audio model by up to 3.9% when both are tested on audio-only data, suggesting that visual information facilitates the acquisition of acoustic distinctions. This work demonstrates that visual information benefits an ideal learner, suggesting that children may leverage visual cues when learning phonemic categories.
