In many psychophysical experiments, the participant's task is to detect small changes along a given stimulus dimension or to identify the direction (e.g., upward vs. downward) of such changes. The results of these experiments are traditionally analyzed with a constant-variance Gaussian (CVG) model or a high-threshold (HT) model. Here, the authors…

Four dual-task experiments examined visuospatial, articulatory, and central executive working memory involvement during the development and application of spatial mental models. In Experiments 1 and 2 participants read route and survey spatial descriptions while undertaking one of four secondary tasks targeting working memory components.…

What differentiates the professional development school (PDS) from other schools are the people and the roles they have created to enact the functions or goals unique to the PDS model: preparation of teacher candidates; enhanced professional learning for educators; improved student achievement through the simultaneous renewal of university and…

Based on my own research education courses for doctoral students, I examine the ways in which music provides powerful and rich models for perception, conceptualisation and engagement for both listeners and performers, to cultivate the processes and products of qualitative research in the social science in general, and in music education in…

Delworth noted in her articulation of the Assessment-Intervention of Student Problems (AISP) model (Chapter Two, this volume) that a campus intervention team (CIT) is necessitated by "insufficient coordination, inadequate information flow, and lack of a shared process." These concerns are potentially most acute with respect to working with…

Three picture-word interference (PWI) experiments assessed the extent to which embedded subset words are activated during the identification of spoken superset words (e.g., "bone" in "trombone"). Participants named aloud pictures (e.g., "brain") while spoken distractors were presented. In the critical condition,…

When a moving object abruptly disappears, this profoundly influences its localization by the visual system. In Experiment 1, 2 aligned objects moved across the screen, and 1 of them abruptly disappeared. Observers reported seeing the objects misaligned at the time of the offset, with the continuing object leading. Experiment 2 showed that the…

The current study lays the groundwork for a model of Mandarin tones based on both native speakers' and non-native speakers' perception and production. It demonstrates that there is variability in non-native speakers' tone productions and that there are differences in the perceptual boundaries in native speakers and non-native speakers. There…

Speech utterances are more than the linear concatenation of individual phonemes or words. They are organized by prosodic structures comprising phonological units of different sizes (e.g., syllable, foot, word, and phrase) and the prominence relations among them. As the linguistic structure of spoken languages, prosody serves an important function…

Variables influencing inferences about a stranger's goal during an unsolicited social interaction were explored. Experiment 1 developed a procedure for identifying cues. Experiments 2 and 3 assessed the relative importance of various cues (space, time, characteristics of oneself, characteristics of the stranger, and the stranger's behavior) for…

A novel method of localizing the direction of a source of sound has evolved in the auditory system of certain small parasitic flies. A mechanical model of this design has been shown to describe the system well. Here, a simplified version of this mechanical model is presented which demonstrates the key feature: direction estimates of high accuracy…

Two divided visual field lexical decision experiments were conducted to examine the role of the cerebral hemispheres in orthographic neighborhood effects. In Experiment 1, we employed two types of words: words with many substitution neighbors (high-"N") and words with few substitution neighbors (low-"N"). Results showed a facilitative effect of…

The current dissertation investigated clear speech production of Korean stops to examine the proposal that the phonetic targets of phonological categories are more closely approximated in hyperarticulated speech. The investigation also considered a sound change currently underway in Korean stops: younger speakers of the Seoul dialect produce the…

The aim of this study was to provide evidence that memory and perceptual processing are underpinned by the same mechanisms. Specifically, the authors conducted 3 experiments that emphasized the sensory aspect of memory traces. They examined their predictions with a short-term priming paradigm based on 2 distinct phases: a learning phase consisting…

It is now widely accepted that sensitivity to goal-directed actions emerges during the first year of life. However, controversy still surrounds the question of how this sensitivity emerges and develops. One set of views emphasizes the role of observing behavioral cues, while another emphasizes the role of experience with producing own action. In a…
