Caregiver executive functions (EFs) play an integral role in shaping cognitive development. Here, we investigated how caregiver EF abilities (86 caregivers; "mean age" = 33.4 years, SD = 4.5) was associated with visual working memory (VWM) in infants (86 infants females; mean age = 250.6 days, SD = 35.8). The BRIEF-A was used to assess…

Assessing children's working memory capacity (WMC) can be challenging for a variety of reasons, including the rapid increase in WMC across early childhood. Here, we developed and piloted an adapted WMC task, which involved minimal equipment, could be performed rapidly, and did not rely on verbal production ability (to facilitate the use of the…

We tested 8- and 10-month-old infants' visual working memory (VWM) for object-location bindings--"what is where"--with a novel paradigm, Delayed Match Retrieval, that measured infants' anticipatory gaze responses (using a Tobii T120 eye tracker). In an inversion of Delayed-Match-to-Sample tasks and with inspiration from the game…

The objective of this study was to examine the role of the stimulus material for the prediction of later IQ by early learning measures in the Visual Expectation Paradigm (VExP). The VExP was assessed at 9?months using two types of stimuli, Greebles and human faces. Greebles were assumed to be associated with a higher load on working memory in…

Humans have the ability to attentionally select the most relevant visual information from their extrapersonal world and to retain it in a temporary buffer, known as visual short-term memory (VSTM). Research suggests that at least two non-contiguous items can be selected simultaneously when they are distributed across the two visual hemifields. In…

In recent years, the intersection of cognitive psychology, developmental psychology, and neuroscience with regard to deaf individuals has received increasing attention from a variety of academic and educational audiences. Both research and pedagogy have addressed questions about whether deaf children learn in the same ways that hearing children…

To examine the development of visual short-term memory (VSTM) for location, we presented 6- to 12-month-old infants (N = 199) with two side-by-side stimulus streams. In each stream, arrays of colored circles continually appeared, disappeared, and reappeared. In the "changing" stream, the location of one or more items changed in each cycle; in the…

Our goal in the present study was to examine the effects of maternal smoking during pregnancy on infant self-regulation, exploring birth weight as a mediator and sex as a moderator of risk. A prospective sample of 218 infants was assessed at 6 months of age. Infants completed a battery of tasks assessing working memory/inhibition, attention, and…

The change detection task has been used in dozens of studies with adults to measure visual working memory capacity. Two studies have recently tested children in this task, suggesting a gradual increase in capacity from 5 years to adulthood. These results contrast with findings from an infant looking paradigm suggesting that capacity reaches…

We compared working memory (WM) for the location of social versus non-social targets in infant siblings of children with Autism Spectrum Disorders (sibs-ASD, n = 25) and of typically developing children (sibs-TD, n = 30) at 6.5 and 9 months of age. There was a significant interaction of risk group and target type on WM, in which the sibs-ASD had…

Previous studies have shown that as a group 6-month-old infants successfully discriminate numerical changes when the values differ by at least a 1:2 ratio but fail at a 2:3 ratio (e.g. 8 vs. 16 but not 8 vs. 12). However, no studies have yet examined individual differences in number discrimination in infancy. Using a novel numerical change…

Two experiments using event-related potentials (ERPs) investigated recognition memory in infants. ERPs were recorded to 100 identical aural stimuli. Fifty familiar and 50 novel stimuli were presented 24 hours later. Results suggest that establishment of memory trace involved a process by which responses to repeated events were more consistent when…

We report a new method for calibrating differences in perceptual salience across feature dimensions, in infants. The problem of inter-dimensional salience arises in many areas of infant studies, but a general method for addressing the problem has not previously been described. Our method is based on a preferential looking paradigm, adapted to…

The capacity of six-month-old infants to maintain information in working memory for several seconds was studied using two versions of an oculomotor delayed response task. The results indicated that infants maintained information about stimulus locations in working memory for three to five seconds. (MDM)

Three experiments explored the effect of introducing novel information about a central target after a short delay on six-month-old's recognition of the original target, the novel exposure target, and a completely novel one. They found that the infants' memory of a central target is resistant to impairment by conflicting postevent information after…
