The present study sought to evaluate trial designs and training designs that are commonly used in popular commercially available computer-assisted language-learning (CALL) programs. The first two experiments (Experiment 1a and 1b) compared the effects of passive viewing and active student response methods in vocabulary learning. Contingencies on…

The ability to shield against distraction while focusing on a task requires the operation of executive functions and is essential for successful learning. We investigated the short-term dynamics of distraction control in a data set of 269 children aged 4-10 years and 51 adults pooled from three studies using multilevel models. Participants…

Visual working memory (VWM) refers to the temporary storage and manipulation of visual information. Although visually different, objects we view and remember can share the same higher-level category information, such as an apple, orange, and banana all being classified as fruit. We study the influence of category information on VWM, focusing on…

In any visual search task in the lab or in the world, observers will make errors. Those errors can be categorized as "deterministic": If you miss this target in this display once, you will definitely miss it again. Alternatively, errors can be "stochastic", occurring randomly with some probability from trial to trial.…

Previous studies found an impact of language familiarity on face recognition in 9- and 12-month-olds. Own race faces are better recognized when associated with native language, whereas for other race faces, it is with non-native language. The aim of this study is to investigate if language familiarity can also influence abstract pattern…

This study compared the effects of listener training and tact training on the emergence of intraverbal responses in the form of foreign language equivalents of the native language. The study was based on Skinner's verbal operants with a focus on intraverbal responses. All participants received listener training and tact training after which a…

People's everyday lives offer plenty of situations where complex processing of information takes place, in which information needs to transfer across modalities to achieve a behavioral goal. The study examined the differential effects on object detection by a visual, verbal, or auditory cue held in working memory (WM), and the role of concurrent…

Purpose: It is generally accepted that adults use visual cues to improve speech intelligibility in noisy environments, but findings regarding visual speech benefit in children are mixed. We explored factors that contribute to audiovisual (AV) gain in young children's speech understanding. We examined whether there is an AV benefit to…

When Virtual Reality (VR) is used to present learning content, the three-dimensional image is often not sufficient and additional text is required, either in the form of visual or auditory text. Such additional instructional text could be particularly beneficial due to the many visual stimuli and the risk of visual working memory overload.…

Since birth, infants develop the ability to perceive a wide range of intersensory relations among various kinds of amodal temporal information. This study addresses the development of the ability to perceive duration-based intersensory relations. Three groups of infants, four, seven and 10 months old, participated in two trials of an intersensory…

The purpose of this study was to investigate sub-lexical segmentation in Spanish-speaking children based on the perception of regular syllables (pseudomorphemes), as well as their association with a visual referent. Both of these skills are the precursors to learning morphology for language acquisition. Twenty-three 12-month-old children…

Previous experimental work shows that negation processing can be direct in bipolar contexts where positive/negative states of affairs can be expressed by available lexical opposites (remember/forget) in monolingual speakers. However, in a unipolar context where such opposites are not available (sing/not sing), the processing first proceeds through…

People perform poorly at sighting missing and wanted persons in simulated searches due to attention and face recognition failures. We manipulated participants' expectations of encountering a target person and the within-person variability of the targets' photographs studied in a laboratory-based and a field-based prospective person memory task. We…

Successful word recognition requires that listeners attend to differences that are phonemic in the language while also remaining flexible to the variation introduced by different voices and accents. Previous work has demonstrated that American-English-learning 19-month-olds are able to balance these demands: although one-off one-feature…

The same-different task is a classic paradigm that requires participants to judge whether two successively presented stimuli are the same or different. While this task is simple, with results that have been replicated many times, response times (RTs) and accuracy for both same and different decisions remain difficult to model. The biggest obstacle…
