This case study of a math and science teacher in a private religious school looks at the impact of a teacher's religious beliefs on her experience of engaging with ethical issues in her practice. A Freirean ethical framework is used to analyze her struggles with differences between her own personal religious convictions and those of the school in…

The stress that negatively affects teachers has been found to influence the turnover rate in the teaching profession. Recent research has shown that mindfulness-based programmes effectively promote well-being while addressing psychological distress. In this study, the authors investigated the effects of a six-week mindfulness-based programme on…

This dissertation investigates how knowledge of phonological generalizations influences speech perception, with a particular focus on evidence that phonological processing is autonomous from (rather than interactive with) auditory processing. A model is proposed in which auditory cue constraints and markedness constraints interact to determine a…

In a variety of conflict paradigms, target and distractor stimuli are defined in terms of perceptual features. Interference evoked by distractor stimuli tends to be reduced when the ratio of congruent to incongruent trials is decreased, suggesting conflict-induced perceptual filtering (i.e., adjusting the processing weights assigned to stimuli…

Visual STM (VSTM) is thought to be related to visual attention in several ways. Attention controls access to VSTM during memory encoding and plays a role in the maintenance of stored information by strengthening memorized content. We investigated the involvement of visual attention in recall from VSTM. In two experiments, we measured…

Previous research has shown that words presented on metaphor congruent locations (e.g., positive words "up" on the screen and negative words "down" on the screen) are categorized faster than words presented on metaphor incongruent locations (e.g., positive words "down" and negative words "up"). These…

This article presents an eye-tracking study using a novel combination of visual saliency maps and "area-of-interest" analyses to explore online feature extraction during category learning in infants. Category learning in 12-month-olds (N = 22) involved a transition from looking at high-saliency image regions to looking at more…

Visual perceptual learning (PL) and perceptual expertise (PE) traditionally lead to different training effects and recruit different brain areas, but reasons for these differences are largely unknown. Here, we tested how the learning history influences visual object representations. Two groups were trained with tasks typically used in PL or PE…

Grapheme-color synesthesia is an atypical condition in which individuals experience sensations of color when reading printed graphemes such as letters and digits. For some grapheme-color synesthetes, seeing a printed grapheme triggers a sensation of color, but "hearing" the name of a grapheme does not. This dissociation allowed us to…

Extensive research has focused on face recognition, and much is known about this topic. However, much of this work seems to be based on an assumption that faces are the most important aspect of person recognition. Here we test this assumption in two experiments. We show that when viewers are forced to choose, they "do" use the face more than the…

Stereotypes, expectations, and emotions influence an observer's ability to detect and categorize objects as guns. In light of recent work in action-perception interactions, however, there is another unexplored factor that may be critical: The action choices available to the perceiver. In five experiments, participants determined whether another…

The current study focuses on the relationship between alerting and executive attention. Previous studies reported an increased flanker congruency effect following alerting cues. In the first two experiments, we found that the alertness-congruency interaction did not exist for all executive tasks (it appeared for a flanker task but not for a Stroop…

Heterotrimeric G(o) is an abundant brain protein required for negatively reinforced short-term associative olfactory memory in "Drosophila". G(o) is the only known substrate of the S1 subunit of pertussis toxin (PTX) in fly, and acute expression of PTX within the mushroom body neurons (MB) induces a reversible deficit in associative olfactory…

The world of man-made design is all around, in everyday objects and appliances people use without a second thought. In this exercise, students have an opportunity to challenge the common refrigerator's design--and improve it. This approach can be used with many other appliances.

Event-related brain potentials (ERPs) were recorded during a Chinese character decision task to examine whether N400 amplitude is modulated by stimulus font. Results revealed large negative-going ERPs in an N400 time window of 300-500 ms to stimuli presented in degraded Xing Kai Ti (XKT) font compared with more intact Song Ti (ST) font regardless…
