Used new test to determine whether 24-month olds interpret novel words in accordance with Mutual Exclusivity Bias. Found that when asked to select exemplars of a familiar noun, they avoided objects from previously read story in which novel nouns were used as atypical exemplars of familiar noun. When pronouns and proper names replaced novel nouns,…

Ten toddlers produced tokens of phonologically individualized words over 12 experimental sessions. Productions in later sessions were significantly shorter in vowel and overall duration than in the early sessions. Familiarity seemed to influence duration of early productions of novel words, and these findings are discussed as evidence of…

Fifty-four young professionals in their first job after apprenticeship described their task-related and private interactions at work during five days, using a variant of the Rochester Interaction Records self-observation method (Reis and Wheeler, 1991). Results showed that more task-related interactions were reported than private interactions at…

Some teachers are uncomfortable with teaching ethics, a subject that science teachers often have very little experience with. Ethics as a discipline is full of unfamiliar terms and its own jargon. Other teachers fear classroom discussions getting out of control, degenerating into a battle of opinions, or having parents and administrators confuse…

Four task-switching experiments examined the notion of an exogenous component of task-set reconfiguration (i.e., a process needed to shift task set that is not initiated in the absence of a task-associated figuration stimulus). The authors varied the complexity and familiarity of stimulus-response (SR) mapping rules to produce differentially…

A 2-high-threshold signal detection (HTSDT) model, a mixture distribution (SON) model, and 2-highthreshold (HT) models with responses distributed over 1 or several response categories were fit to results of 6 experiments from 2 studies on associative recognition: R. Kelley and J. T. Wixted (2001) and A. P. Yonelinas (1997). HTSDT assumes that…

K. J. Malmberg, J. Holden, and R. M. Shiffrin (2004) reported more false alarms for low- than high-frequency words when the foils were similar to the targets. According to the source of activation confusion (SAC) model of memory, that pattern is based on recollection of an underspecified episodic trace rather than the error-prone familiarity…

The effects of lexicality on auditory change detection based on auditory sensory memory representations were investigated by presenting oddball sequences of repeatedly presented stimuli, while participants ignored the auditory stimuli. In a cross-linguistic study of Hungarian and German participants, stimulus sequences were composed of words that…

The overclaiming technique requires respondents to rate their familiarity with a list of general knowledge items (persons, places, things). Because 20[percent] of the items are foils (i.e., do not exist), the response pattern can be analyzed with signal detection methods to yield the accuracy and bias scores for each respondent. In Study 1, the…

The results of an experimental study investigating the influence of problem familiarity on learning in a problem-based psychology course are presented. Participants worked with either a "familiar" or an "unfamiliar" version of the same problem. The following measurements were taken (1) a measure of problem quality as perceived by students, (2)…

This study examined the extent to which student engagement is associated with a traditional assessment of student knowledge. In this study, ETS Business Major Field Test (MFT) scores were compared to student's self-reported survey responses to specific questions on the National Survey of Student Engagement (NSSE). Areas of the NSSE survey such as…

Giant exploding volcanoes...asteroids crashing into Earth...continents floating across the oceans...massive pools of lava...violent earthquakes splitting continents--middle school students hold a variety of ideas about Earth, how it has changed over time, and what has caused these changes. Listening to students talk about how the world works is…

Recognition memory, involving the ability to discriminate between a novel and familiar object, depends on the integrity of the perirhinal cortex (PRH). Glutamate, the main excitatory neurotransmitter in the cortex, is essential for many types of memory processes. Of the subtypes of glutamate receptor, metabotropic receptors (mGluRs) have received…

The author provides a preliminary assessment of the extent to which a sample of 264 school social workers are aware of the Internet-related problems children are experiencing and proposes ways in which Internet-related problems could affect youths' social and academic competence and performance in a school setting. The findings have implications…

This paper presents a model--"hypertextual function"--to consider teachers' thinking, practice, and development in the use of technology. Hypertextual function is a multi-dimensional model linking a teacher's knowledge about students ("familiarity") and technology ("facility"), with a teacher's teaching practice of integrating technology with…
