This cross-sectional study investigated the bilingual lexical skills of 175 US school-age children (5 to 18 years old) with Cantonese, Mandarin, or Korean as their heritage language (HL), and English as their dominant language. Primary study goals were to identify potential patterns of development in bilingual lexical skills over the elementary to…

The aim of this study was to analyse the effects of a school-based intervention to promote physical activity, utilising the postulates of the trans-contextual model of motivation. The study examined two separate classes of elementary school students (mean age 11.28?years), one of which served as the control group (n?=?26) and the other as the…

This paper reports on one phase of a long-term project investigating mathematical content knowledge of pre-service teachers. A cohort of second year PSTs conducted a diagnostic assessment and a series of associated tutoring sessions with a primary aged child. The focus here is on the PSTs' ability to make appropriate task choices following the…

The purpose of this study was to explore the experiences and perceptions of early childhood preservice teachers in a southeastern university as they worked for mastery of phonemic awareness, phonics, and morphemic awareness. Mastery was set at 90% accuracy in a series of tests, which required them to perform different tasks related to the said…

There is evidence that 4.5-month-olds do not always use surface pattern to individuate objects but that they can be primed to attend to pattern differences through select experiences. For example, if infants are first shown events in which the pattern of an object predicts its function (dotted containers pound and striped containers pour), they…

How do the characteristics of sounds influence the allocation of visual-spatial attention? Natural sounds typically change in frequency. Here we demonstrate that the direction of frequency change guides visual-spatial attention more strongly than the average or ending frequency, and provide evidence suggesting that this cross-modal effect may be…

Ample evidence suggests that global perception may involve low spatial frequency (LSF) processing and that local perception may involve high spatial frequency (HSF) processing (Shulman, Sullivan, Gish, & Sakoda, 1986; Shulman & Wilson, 1987; Robertson, 1996). It is debated whether SF selection is a low-level mechanism associating global…

Participants' reaction time (RT) data in a prime-probe flanker task (e.g., ABA-CAC) were analyzed in terms of the characteristics of RT distribution to examine possible mechanisms that produce negative priming. When the prime and probe were presented in the same context and the proportion of repetition-target trials (TRP) was 0.33, negative…

Recent evidence suggests that the recognition of an object's presence and its explicit recognition are temporally closely related. Here we re-examined the time course (using a fine and a coarse temporal resolution) and the sensitivity of three possible component processes of visual object recognition. In particular, participants saw briefly…

Brain-imaging research has shown that a viewed acting hand is mapped to the observer's hand representation that corresponds with the identity of the hand. In contrast, behavioral research has suggested that rather than representing a seen hand in relation to one's own manual system, it is represented in relation to the midline of an imaginary…

This article documents a fairly rare kind of interlanguage phenomenon, namely one in which interlanguages exhibit syntactic constructions that are grammatical neither in a learner's native language nor in his or her target language, but are nevertheless typologically attested. The target construction is "wh"-scope marking, a cross-linguistically…

College students frequently experience inattentive and hyperactive concerns. In multiple independent samples and three randomised experiments, we examined multiple versions of a short performance-based measure translated from basic research on how organisms learn sequential stimuli patterns when such patterns are interleaved with information that…

This paper reports use of sample stimulus control shaping procedures to teach arbitrary matching-to-sample to 2 capuchin monkeys ("Cebus apella"). The procedures started with identity matching-to-sample. During shaping, stimulus features of the sample were altered gradually, rendering samples and comparisons increasingly physically dissimilar. The…

This study takes inventory of available evidence on response repetition (RR) effects in task switching, in particular the evidence for RR cost when the task switches. The review reveals that relatively few task-switching studies in which RR effects were addressed have shown statistical support for RR cost, and that almost all are affected by 1 of…

This study examined the capability of the left hemisphere (LH) and the right hemisphere (RH) to perform a visual recognition task independently as formulated by the Direct Access Model (Fernandino, Iacoboni, & Zaidel, 2007). Healthy native Hebrew speakers were asked to categorize nouns and non-words (created from nouns by transposing two middle…
