Here we report evidence from a new eye-tracking measure of relational memory that suggests 9-month-old infants can encode memories in terms the relations among items, function putatively subserved by hippocampus. Infants learned about association between faces were superimposed on unique scenic backgrounds. During test trials, shown three presented familiar scene. All equally familiar; however, one had been with background earlier. Visual behavior was recorded continuously using TOBII eye...
Performance on the visual paired-comparison (VPC) task has typically been interpreted with E. Sokolov's (1963) comparator model of orienting response; novelty preferences are as evidence retention, whereas null forgetting. Here authors capitalized verbal nature human adults to clarify interpretation in VPC performance. In 2 experiments, were tested either or a forced-choice recognition after delays 3 min 12 months. Experiment 1, exhibited short delays, intermediate and familiarity long...
Abstract In a series of three experiments, we examined the effects familiarization time, retention interval, and changes in environmental context on adults' performance visual paired‐comparison (VPC) task. The magnitude novelty preference increased as time increased, decreased interval was impaired by change after delay. These data are highly consistent with obtained prior studies using VPC task infants suggest that could be used to measure memory across life span. © 2004 Wiley Periodicals,...
Categorical perception, demonstrated as reduced discrimination of within‐category relative to between‐category differences in stimuli, has been found a variety perceptual domains adults. To examine the development categorical perception domain facial expression processing, we used behavioral and event‐related potential (ERP) methods assess (happy‐happy) (happy‐sad) expressions 7‐month‐old infants. Data from visual paired‐comparison test recordings attention‐sensitive ERPs showed no...
Individuals with Down syndrome (DS) exhibit a behavioral phenotype of specific strengths and weaknesses, in addition to generalized cognitive delay. In particular, adults DS deficits learning memory processes that depend on the hippocampus, there is some suggestion impairments executive function tasks prefrontal cortex. While these functions have been investigated DS, it largely unclear how develop young children DS. Here we tested preschoolers typically developing children, age-matched...
Sleep has a beneficial effect on consolidation of newly learned fine motor skills. The aim the current study was to determine whether sleep similar gross A total 70 participants were randomly assigned either sleep-wake group or wake-sleep and trained an arm coordinated reaching task as skill. Initial training occurred in evening for morning Wake-Sleep group. All attended two test sessions 12 24 hours following initial training. Gross skill performance improved both groups night but not after...
Humans rapidly and spontaneously activate muscles in the face when viewing emotional facial expressions others. These rapid reactions (RFRs) are thought to reflect low-level, bottom-up processes, theorized assist an observer experience share affect of another individual. It has been assumed that RFRs present from birth; however date, no study investigated this response children younger than 3 years age. In study, we used electromyography (EMG) measure corrugator supercilii (brow) zygomaticus...
Relational memory, or the ability to bind components of an event into a network linked representations, is primary function hippocampus. Here we extend eye-tracking research showing that infants are capable forming memories for relation between arbitrarily paired scenes and faces, by looking at age-related changes in relational memory over first year life. Six- 12-month-old were familiarized with pairs faces before being tested arrays three familiar presented on scene. Preferential face...
Maternal-infant bonding is important for children's positive development. Poor maternal-infant a risk factor negative mother and infant outcomes. Although researchers have examined individual predictors of bonding, studies typically do not examine several concurrent longitudinal within the same model. This study aimed to evaluate unique combined predictive power cross-sectional bonding. Participants were 372 pregnant women recruited from an Australian hospital. Data collected mothers at...
The medial temporal lobes (MTL) support declarative memory and mature structurally functionally during the postnatal years in humans. Although recent work has addressed development of early childhood, less is known about continued beyond this period time. purpose investigation was to explore MTL-dependent across middle childhood. Children (6 -10 old) adults completed two computerized tasks, place learning (PL) transitive inference (TI), that each examined relational memory, as well flexible...
Abstract Poor early life care often relates to cognitive difficulties. However, newer work suggests that in early‐life, adversity may associate with enhanced or accelerated neurodevelopment. We examine associations between postnatal caregiving risks (i.e., higher self‐reported postnatal‐anxiety and lower observed maternal sensitivity) infant relational memory via deferred imitation binding). Using subsamples of 67–181 infants (aged 433–477 post‐conceptual days, roughly five seven months...
Background With the arrival of generative artificial intelligence (genAI) tools, psychology educators are rethinking their assessment practices. Objective This paper describes one approach to integrating genAI into an designed promote psychological literacy. Method Students used ChatGPT generate a media release about published article and then wrote critique. We evaluated whether students were able use marking rubric assess output, working with early in process had benefits for grades on...
Small‐scale eye‐tracking research lends support to behavioral studies of relational memory by 6 months life. Here, in the largest test date ( n = 276), we replicate these findings and examine impact excluding data based on looking behavior characteristics at test. Past work examining infants' preferential toward arbitrary‐paired objects scenes has excluded infants from analysis upon “insufficient looking” Yet, suggests that variation may be associated with patterns during encoding, as well...
The fields of developmental psychology and neuroscience have existed independently one another for many years. This is unfortunate, as knowledge how the brain develops can inform study behavioral development. In this paper, we provide two examples about development has improved our understanding key domains: face processing memory We conclude with a plea other domains to integrate information from both sciences.
Emotional expressions evoke rapid facial reactions in the perceiver that are consistent with valence of observed expression. We aimed to investigate whether this robust reaction is purely a motor matching response or instead represents underlying affective processes. Participants' (N = 60) corrugator supercilii and zygomaticus major muscle activity was quantified using electromyography (EMG) while they viewed three sets images; (i) upright happy angry expressions, (ii) inverted (iii) sad...
Abstract Although open science has become a popular tool to combat the replication crisis, it is unclear whether uptake of practices been consistent across field psychology. In this study, we were particularly interested in claims that developmental psychology lags behind other subfields adopting valid. To test this, determined data and material sharing differed as function psychological subfield at distinguished journal, Psychological Science . The results showed materials scores increased...
