Observers' memory for a person's appearance can be compromised by the presence of a weapon, a phenomenon known as the weapon-focus effect (WFE). According to the unusual-item hypothesis, attention shifts from the perpetrator to the weapon because a weapon is an unusual object in many contexts. To test this assumption, we monitored participants'…

We examined the relationship between the Early start Denver model (ESDM) intervention and mu rhythm attenuation, an EEG paradigm reflecting neural processes associated with action perception and social information processing. Children were assigned to either receive comprehensive ESDM intervention for two years, or were encouraged to pursue…

Matching unfamiliar faces is highly error-prone, and most studies highlight the implications for real-world ID-checking. Here we study a particular instance of ID-checking: proof of age for buying restricted goods such as alcohol. In this case, checkers must establish that an identity document is carried by its legitimate owner (i.e., that the ID…

Adolescents who experience social anxiety often display distressing fears that unfamiliar individuals evaluate their performance in social settings. These fears typically manifest as fears of negative evaluation (FNE) and/or fears of positive evaluation (FPE). Two well-established survey measures were originally developed to assess these…

In direct interactions with others, 9-month-old infants' learning about objects is facilitated when the interaction partner addresses the infant through eye contact before looking toward an object. In this study we investigated whether similar factors promote infants' observational learning from third-party interactions. In Experiment 1,…

Adolescents experiencing social anxiety often engage in safety behaviors--covert avoidance strategies for managing distress (e.g., avoiding eye contact)--that factor into the development and maintenance of their concerns. Prior work supports the psychometric properties of the Subtle Avoidance Frequency Examination (SAFE), a self-report survey of…

Familiarity and distance is an issue that is much discussed in ethnographic fieldwork. This paper focuses on the topic of balancing familiarity and distance when the researcher is directly or indirectly part of the field, which in the study consists of an adult education context of two different teacher-training courses for upper secondary…

A number of theories exist to explain why people gesture when speaking, when they produce gesture, and the origin of their gestures. This dissertation focuses on four individual variables that can influence gesture: (i) familiarity, (ii) imageability, (iii) codability, and (iv) motor experience. Four experiments were designed to determine how each…

This study assessed whether olfactory familiarization can render food odors more pleasant, and consequently food more attractive, to children with autism spectrum disorder. Participants were first presented with a series of food odors (session 1). Then, they were familiarized on four occasions (time window: 5 weeks) with one of the two most…

This paper investigates mothers' views regarding the purpose of shared reading with their two-year-old children, confidence in using printed and electronic texts, and self-reported practice, framed around a focus on mothers' motivation to engage in shared reading with their children. Research into adult-child shared reading experiences has…

Language provides rich social information about its speakers. For instance, adults and children make inferences about a speaker's social identity, geographic origins, and group membership based on her language and accent. Although infants prefer speakers of familiar languages (Kinzler, Dupoux, & Spelke, 2007), little is known about the…

The design and development processes of instructional materials might be considered simple and clear because the pre-established instructional goals can lead the way. However, in practice, there are lots of issues to be considered during these processes. The quality of the material, appropriate visual design, usability, and acceptable amount of…

Students with autism spectrum disorder (ASD) are often challenged by social interaction and may require substantial support to interact with peers even in inclusive settings. Having adults support students with ASD during peer interactions, however, may ostracize the student from peers without disabilities. Peer-mediated strategies are needed so…

In this multi-case qualitative study the degree to which school-based decision-making (SBDM) is understood and conceptualised by the members of school governing bodies (SGBs)--educators, chairpersons of SGBs, principals, and learner representative councils-as well the extent to which decisions were shared among the various groups represented on…

Background: In recent years many studies have shown that the use of cochlear implants (CIs) improves children's skills in processing the auditory signal and, consequently, the development of both language comprehension and production. Nevertheless, many authors have also reported that the development of language skills in children with CIs is…
