Labels and object categorization in six- and nine-month-olds: tracking labels across varying carrier phrases

Language shapes object categorization in infants. This starts as a general enhanced attentional effect of language, which narrows to a specific link between labels and categories by twelve months. The current experiments examined this narrowing effect by investigating when infants track a consistent label across varied input. Six-month-old infants (N = 48) were familiarized to category exemplars, each presented with the exact same labeling phrase or the same label in different phrases. Evidence of object categorization at test was only found with the same phrase, suggesting that infants were not tracking the label’s consistency, but rather that of the entire input. Nine-month-olds (N = 24) did show evidence of categorization across the varied phrases, suggesting that they were tracking the consistent label across the varied input.     

Breaking Surface Feature Continuity of Previewed Mask Reinstates Object Substitution Masking12

Perception of a briefly presented target is impaired when a sparse surrounding mask (e.g., four-dot) persists after target offset compared to when the target and mask offset together (i.e., object substitution masking [OSM]). Previous studies have reported a mask preview effect in which OSM is largely attenuated by prior presentation of the mask. Here, we investigated how breaking object continuity of the previewed mask affects the mask preview effect. Introducing an abrupt surface color change of the previewed mask at target onset disrupted the beneficial effect of mask preview, that is, OSM was reinstated (Experiment 1). The masking induced by mask color change exhibited the same two characteristics as conventional OSM: target location specificity and non-necessity of voluntary attention to the mask (Experiment 2). These results suggest that a sudden change in surface color breaks object continuity of the previewed mask and causes the mask to be represented as a new one, which triggers OSM anew.

Occupational Identity,Competence, and Environments Among Adults With and Without Attention Deficit Hyperactivity Disorder

Exploring occupational adaptation among adults with attention deficit hyperactivity disorder (ADHD) is essential due to associated occupational difficulties. Occupational Performance History Interview scales—identity, competence, and environments—were compared between 51 adults with and 50 without ADHD who participated in occupations. Internal and external resources supporting occupational participations were represented by the competence and environment scales, respectively. The group with ADHD reported fewer internal and external occupational resources compared to the group without ADHD, despite occupational identity similarities. Study findings suggest that occupational interventions aimed at increasing internal and external occupational resources may support occupational adaptation among adults with ADHD.     

The influence of popular media characters on children's object choices

Children often prefer objects and food packaging bearing images of popular media characters. However, it is unclear what factors may influence this. This study investigated whether depictions of popular media characters on high-quality (brand new) and low-quality (dirty, broken) objects influenced 3- to 4-year-old children's (N = 84) object preferences, as well as which objects children selected to help them complete a functional task (e.g., using a bucket to transport several small items). We also investigated whether children's preferences were related to inhibitory control. We found children's preferences were influenced by images of popular characters, but not their choice of objects for functional use. Instead, children relied on object quality when selecting an object to complete a task. Inhibitory control was not related to children's object choices. These results suggest children may weigh object features differently when making decisions for different purposes.
