The measurement of pupil diameter in psychology (in short, "pupillometry") has just celebrated 50 years. method established itself after the appearance three seminal studies (Hess & Polt, 1960, 1964; Kahneman Beatty, 1966). Since then, continued to play a significant role within field, and pupillary responses have been successfully used provide an estimate "intensity" mental activity changes states, particularly allocation attention consolidation perception. Remarkably, continuous measure...
Pupillometry is the study of changes in diameter pupil as a function cognitive processing. This review paper provides brief historical overview pupillometry science. The physiology pupillary responses introduced, leading to an outline early work, which began with seminal work Hess and Polt 1960s. then presents broad contemporary research sciences that relies on pupillometry. organized around five general domains, namely perception, language processing, memory decision making, emotion...
The violation-of-expectation (VOE) paradigm and related methods are the main tools used to study high-level cognition in preverbal infants. Infants' differential looking conceptually implausible/impossible events has been as an index of early cognitive competence many areas, including object knowledge, physics, language, number. However, event's plausibility is commonly confounded with its perceptual novelty or familiarity, leading a variety interpretations for time data (Bogartz, Shinskey &...
Much of our basic understanding cognitive and social processes in infancy relies on measures looking time, specifically infants’ visual preference for a novel or familiar stimulus. However, despite being the foundation many behavioral tasks infant research, determinants preferences are poorly understood, differences expression can be difficult to interpret. In this large-scale study, we test predictions from Hunter Ames model infants' preferences. We investigate effects three factors...
Abstract Neuroconstructivism: How the Brain Constructs Cognition proposes a unifying framework for study of cognitive development that brings together (1) constructivism (which views as progressive elaboration increasingly complex structures), (2) neuroscience aims to understand neural mechanisms underlying behavior), and (3) computational modeling formal explicit specifications information processing). The guiding principle our approach is context dependence , within (in contrast Marr...
Measuring eye movements remotely via the participant's webcam promises to be an attractive methodological addition in-person eye-tracking in lab. However, there is a lack of systematic research comparing remote web-based with in-lab young children. We report multi-lab study that compared these two measures anticipatory looking task toddlers using WebGazer.js and jsPsych. Results our tested sample 18-27-month-old (N = 125) revealed successfully captured goal-based action predictions, although...
This paper examines the relative merits of looking time and pupil diameter measures in study early cognitive abilities infants. Ten-month-old infants took part a modified version classic drawbridge experiment used to object permanence (Baillargeon, Spelke, & Wasserman, 1985). The involved factorial design where angle rotation presence or absence an were crossed. Looking results are consistent with previous work could suggest if one ignored data from all cells design. When considered, rather...
Habituation and related procedures are the primary behavioral tools used to assess perceptual cognitive competence in early infancy. This article introduces a neurally constrained computational model of infant habituation. The combines two leading process theories habituation into single functional system that is grounded brain circuitry. HAB (for Habituation, Autoassociation, Brain) proposes behaviors emerge from opponent, complementary processes hippocampal selective inhibition cortical...
ABSTRACT Research on early signs of autism in social interactions often focuses infants’ motor behaviors; few studies have focused speech characteristics. This study examines infant‐directed mothers infants later diagnosed with (LDA; n = 12) or typically developing (TD; 11) as well productions (13 LDA, 13 TD). Since LDA appear to behave differently the first months life, it can affect functioning dyadic interactions, especially vocal productions, sensitive expressiveness and emotions...
Infants' expectations of the world around them have been extensively assessed through violation expectation paradigm and related habituation tasks. Typically, in these tasks, longer looking to impossible events following familiarisation with possible equivalents is taken reflect surprise at their occurrence, thus revealing infants' knowledge. In this study, role learning during task itself explored by switching archetypal approach on its head familiarising infants events. a partial...
The rise of pupillometry in infant research over the last decade is associated with a variety methods for data preprocessing and analysis. Although pupil diameter increasingly recognized as an alternative measure popular cumulative looking time approach used many studies (Jackson & Sirois, 2022), open question whether approaches to analyse this variable converge. To end, we proposed crowdsourced A dataset from 30 9-month-old infants (15 girls; M
Previous research suggesting an association between maternal prenatal docosahexaenoic acid (DHA) intake and infant cognition has yet to assess whether there is a critical trimester for the observed effects. We used comprehensive Food Frequency Questionnaire estimate DHA levels during both second third trimesters of pregnancy, in sample 125 pregnant women. Infants were assessed at 4.5 months 9 post-partum using specific tests visual acuity, habituation, attention. Based on mothers subdivided...
This paper reviews a recent article suggesting that infants use system of algebraic rules to learn an artificial grammar (Marcus, Vijayan, Bandi Rao & Vishton, Rule learning by seven‐month‐old infants. Science , 183 (1999), 77–80) . In three reported experiments, exhibited increased responding auditory strings violated the pattern elements they were habituated to. We argue perceptual interpretation is more parsimonious, as well consistent with broad array habituation data, and we report...
This study investigated maternal prenatal docosahexaenoic acid ( DHA ) intake and infant cognitive development at 22 months. Estimates for second‐ third‐trimester levels were obtained using a comprehensive Food Frequency Questionnaire. Infants n = 67) assessed months on novel object search task. Mothers' divided into high or low groups, with analyses revealing significant positive effect of task performance. The third trimester appears to be critical time ensuring adequate facilitate optimum...

Two experiments using a mobile robot examine the performance of neural network model habituation. The input to is video feed from robot's camera, preprocessed visual system. Images, after retinal processing, are translated in frequency domain and Gabor-filtered. output controls motors thus where it looks. In one condition, directly motors. second outputs connected control units via weights that modified with simple Hebbian learning. both cases, behavior reproduces important...
