In baseball, it is believed that "hitting is contagious," that is, probability of success increases if the previous few batters get a hit. Could this effect be partially explained by action induction--that is, the tendency to perform an action related to one that has just been observed? A simulation was used to investigate the effect of inducing…

In this article, the author has equated the principal's relationship with the president of the teachers' union as a dance where each wants to lead and yet there is, as in most relationships, a mutual dependency that makes each person realize that there is a time when one leads and a time when one follows. The author presents the details of when…

The two authors share learning gleaned from personal, classroom experiences in small schools--both cautions and assurances--for other educators who may be embarking on a similar path. We worked at two different small high school sites in the Denver Public Schools, an urban district with an ethnically diverse student population of 78,000. We…

The purpose of this paper is to explore how and when verbal labels facilitate relational reasoning and transfer. We review the research and theory behind two ways words might direct attention to relational information: (1) words generically invite people to compare and thus highlight relations (the Generic Tokens [GT] hypothesis), and/or (2) words…

Students are believed to learn at optimum level with materials with a lot of white space since the existence of vast number of words and limited amount of white space, especially in textbooks may contribute to the increase in anxiety among learners (Tomlinson, 1998). This study evaluates the amount of white space in terms of pixels in the…

The nation's critical infrastructure, information systems, and telecommunication networks are vulnerable and threatened by an ever-growing number of attacks in cyberspace. An essential element of the nation's comprehensive approach to cybersecurity is the ability for the Department of Defense to protect and defend its information enterprise.…

Individuals with aphasia have more problems detecting small differences between speech sounds than larger ones. This paper reports how phonemic processing is impaired and how this is influenced by speechreading. A non-word discrimination task was carried out with "audiovisual", "auditory only" and "visual only" stimulus display. Subjects had to…

Purpose: Professional communities are capable of maintaining their social status and role in society on the basis of a blend of technical and formal expertise, know-how, and an understanding of the non-professional's demands and expectations. In architectural work, professional expertise largely centres on the visual capacities of the architect,…

Courses in a wide variety of disciplines emphasize that what we think important, and are therefore likely to remember, is not the result of the objective situation but rather the result of our individual biases and interpretations. This article presents a classroom exercise that aids students in grasping the interpretive nature of historical…

Rapamycin, an inhibitor of the mammalian target of rapamycin (mTOR) kinase, has attracted interest as a possible prophylactic for post-traumatic stress disorder (PTSD)-associated fear memories. We report here that although rapamycin (40 mg/kg, i.p.) disrupted the consolidation and reconsolidation of fear-potentiated startle paradigm to a…

Recent findings suggest that children with autism may be impaired in the perception of biological motion from moving point-light displays. Some children with autism also have abnormally high motion coherence thresholds. In the current study we tested a group of children with autism and a group of typically developing children aged 5 to 12 years of…

According to one approach to speech perception, listeners perceive speech by applying general pattern matching mechanisms to the acoustic signal (e.g., Diehl, Lotto, & Holt, 2004). An alternative is that listeners perceive the phonetic gestures that structured the acoustic signal (e.g., Fowler, 1986). The two accounts have offered different…

Infants' speech perception abilities change through the first year of life, from broad sensitivity to a wide range of speech contrasts to becoming more finely attuned to their native language. What remains unclear, however, is how this perceptual change relates to brain responses to native language contrasts in terms of the functional…

This article discusses seven chiral odorants that demonstrate the enantioselectivity of odor sensation: carvone, Celery Ketone, camphor, Florhydral, 3-methyl-3-sulfanylhexan-1-ol, muscone, and methyl jasmonate. After a general introduction of the odorant-receptor interaction and the combinatorial code of olfaction, the olfactory properties of the…

Purpose: The current study was an attempt to provide initial evidence on how to predict the optimal language in which to conduct speech perception testing for Spanish/English (S/E) bilingual listeners. Method: Thirty normal-hearing S/E listeners differing in age of language acquisition, length of immersion, daily language use, self-rated listening…
