Three experiments assessed the development of children's part and configural (part-relational) processing in object recognition during adolescence. In total, 312 school children aged 7-16 years and 80 adults were tested in 3-alternative forced choice (3-AFC) tasks. They judged the correct appearance of upright and inverted presented familiar…

The relationship between speech perception and production has been debated for a long time. The Motor Theory of speech perception (Liberman et al., 1989) claims that perceiving speech is identifying the intended articulatory gestures rather than perceiving the sound patterns. It seems to suggest that speech production precedes speech perception,…

The problem investigated in this quasi-experimental study was to educate teachers in how to overcome generational differences that arose when educators of different generations were required to work together in a collaborative professional learning community. Perceptions of work environment and performance, collaboration, and professional learning…

Attachment security and mother-child relationships serve a critical role in human development. Several studies have demonstrated an association between the salutary effects of security-based attachment strategies and mindfulness. This descriptive research study explores this relationship through semi-structured interviews, the Five Facet…

Adult second language (L2) learners often experience difficulty producing and perceiving non-native phonological contrasts. Even highly proficient bilinguals, who have been exposed to an L2 for long periods of time, struggle with difficult contrasts, such as /r/-/l/ for Japanese learners of English. To account for the relative ease or difficulty…

Previous Language Testing research has largely reported that although many raters' characteristics affect their evaluations of language assessments (Reed & Cohen, 2001), being a native speaker or non-native speaker rater does not significantly affect final ratings (Kim, 2009). In Second Language Acquisition, some researchers conclude that…

I taught music in three schools where 10-40% of the student population spoke another language at home. I ran an all-select choir for Kindergarten, Primary, Junior and Intermediate students once per week. I was interested in answering the following questions: What impact might weekly rehearsals of an all-select choir have on language learning? How…

The hypothesis that lonely children show hypervigilance for social threat was examined in a series of three studies that employed different methods including advanced eye-tracking technology. Hypervigilance for social threat was operationalized as hostility to ambiguously motivated social exclusion in a variation of the hostile attribution…

This paper discusses the role of emotions in mobilizing implicit activisms--that is, small-scale, personal, and modest activisms--in schools. For this purpose, the discussion evokes the notion of critical emotional reflexivity to illuminate how creating spaces for critical reflection on emotions may contribute to making implicit activisms more…

Research in second language speech has often focused on listeners' accent judgment and factors that affect their perception. However, the topic of listeners' application of specific sound categories in their own perceptual judgments has not been widely investigated. The current study explored how listeners from diverse language backgrounds weighed…

This study investigated how gifted children with dyslexia might be able to mask literacy problems and the role of possible compensatory mechanisms. The sample consisted of 121 Dutch primary school children that were divided over four groups (typically developing [TD] children, children with dyslexia, gifted children, gifted children with…

The visual complexity of orthographies varies across writing systems. Prior research has shown that complexity strongly influences the initial stage of reading development: the perceptual learning of grapheme forms. This study presents a computational simulation that examines the degree to which visual complexity leads to grapheme learning…

The relations among various spatial and mathematics skills were assessed in a cross-sectional study of 854 children from kindergarten, third, and sixth grades (i.e., 5 to 13 years of age). Children completed a battery of spatial mathematics tests and their scores were submitted to exploratory factor analyses both within and across domains. In the…

This dissertation investigates the hypothesis that the more vowel-like a consonant is, the more difficult it is for listeners to classify it as geminate or singleton. A perceptual account of this observation holds that more vowel-like consonants lack clear markers to signal the beginning and ending of the consonant, so listeners don't perceive the…

Research has shown that lexical tones, a suprasegmental feature, are processed by native speakers as linguistic elements just like other segmental information. Among the four tones of Mandarin Chinese, in particular, Tone 2 and Tone 3 are very similar in their pitch contour shapes and thus can be difficult to distinguish in native and nonnative…
