The present study investigates English-learning infants' early understanding of the link between the grammatical category "verb" and the conceptual category "event," and their ability to recruit morphosyntactic information online to learn novel verb meanings. We report two experiments using an infant-controlled…

When integrated within a holistic literacy program, phonics applications can be used in classrooms to facilitate students' self-directed learning of letter-sound knowledge; but are they designed to allow for such a purpose? With most phonics software applications making heavy use of image cues, this project has more specifically investigated…

Teachers often use in-class questions to examine the level of understanding of their students, while these also enable students to reorganize their acquired knowledge. However, previous studies have shown that students may resist being questioned because of negative emotions. Therefore, this paper proposes the idea of eliciting positive emotions…

Mathematics curricula are frequently rich with visuals, but these visuals are often not designed for optimal use of students' limited cognitive resources. The authors of this study revised the visuals in a mathematics lesson based on instructional design principles. The purpose of this study is to examine the effects of these revised visuals on…

Working memory (WM) is the ability to temporarily store and retrieve a limited amount of information during complex cognitive activities, especially in the face of distraction. The dual-component model describes WM as including active maintenance in primary memory (PM) and cue-dependent search and retrieval from secondary memory (SM). Previously,…

Lesion and inactivation studies indicate that the central amygdala (CeA) participates in the expression of cued and contextual fear, whereas the bed nucleus of the stria terminalis (BNST) is only involved in the latter. The basis for this functional dissociation is unclear because CeA and BNST form similar connections with the amygdala and…

Psycholinguistic experiments conducted with the picture-word interference paradigm are typically preceded by a phase during which participants learn the words they will have to produce in the experiment. In Experiment 1, the pictures (e.g., a frog) were to be named and were presented with a categorically related (e.g., "cat") or…

Introduction: Adaptation to changing situations can be mediated by two strategies: (1) Evaluation of a "response" and (2) Evaluation of "outcome" values in relation to objects. Previous studies indicate that response shifting is associated with a network comprising the left frontal cortex and parietal cortex connected by the superior longitudinal…

Considerable evidence has demonstrated that transient receptor potential (TRP) channels play vital roles in sensory neurons, mediating responses to various environmental stimuli. In contrast, relatively little is known about how TRP channels exert their effects in the central nervous system to control complex behaviors. This is also true for the…

Faces are visually attractive to both human and nonhuman primates. Human neonates are thought to have a broad template for faces at birth and prefer face-like to non-face-like stimuli. To better compare developmental trajectories of face processing phylogenetically, here, we investigated preferences for face-like stimuli in infant rhesus macaques…

The differential allocation of information processing resources over time, here termed "temporal attention," may be achieved by relatively automatic "exogenous" or controlled "endogenous" mechanisms. Over 100 years of research has confounded these theoretically distinct dimensions of temporal attention. The current…

Sensory processing of action effects has been shown to differ from that of externally triggered stimuli, with respect both to the perceived timing of their occurrence (intentional binding) and to their intensity (sensory attenuation). These phenomena are normally attributed to forward action models, such that when action prediction is consistent…

Preschoolers persistently predict that they will perform better than they actually can perform on a picture recall task. The current investigation sought to explore a condition under which young children might be able to improve their predictive accuracy. Namely, children were asked to predict their recall twice for the same set of items.…

This study determined whether using photographic stimuli displaying different ethnicity (African American vs. Caucasian American) influenced preference, word count, and number of content units produced by African American or Caucasian American participants. Six photograph pairs depicting common scenes were developed, differing only by model…

Unilateral deafness has a high incidence in children. In addition to children who are born without hearing in one ear, children with bilateral deafness are frequently equipped only with one cochlear implant, leaving the other ear deaf. The present study investigates the effects of such single-sided deafness during development in the congenitally…
