OBJECTIVE We investigated elementary school children's ability to use a variety of Likert response formats to respond to concrete and abstract items. METHODS 111 children, aged 6-13 years, responded to 2 physical tasks that required them to make objectively verifiable judgments, using a 5-point response format. Then, using 25 items, we ascertained the consistency between responses using a "go...

We investigated the temporal properties of the red - green, blue-yellow, and luminance mechanisms in a contour-integration task which required the linking of orientation across space to detect a 'path'. Reaction times were obtained for simple detection of the stimulus regardless of the presence of a path, and for path detection measured by a yes/no procedure with path and no-path stimuli random...

Social contract theory is incoherent and it does not work as desired. Among the most obvious disanalogies is that contracts are enforced by a third party, commonly the state. There is no such external enforcer for a constitution. Contractarian theorists typically ignore all such issues and use the metaphor of contract very loosely to ground a claim that citizens are morally obligated to defer t...

A 76-year-old woman was admitted for cardiac decompensation, hypertension, and renal failure. To explore her chronic hypertension, urinary fractionated metanephrines were quantified. Fig. 1A shows the chromatogram of the patient’s urine, and Fig. 1B shows the chromatogram of a calibration standard. A very large methoxytyramine peak was observed (Fig. 1A, black arrow). The peak signal was satura...

Problem Description: It should be well known that processors are outstripping memory performance: specifically that memory latencies are not improving as fast as processor cycle time or IPC or memory bandwidth. Thought experiment: imagine that a cache miss takes 10000 cycles to execute. For such a processor instruction level parallelism is useless, because most of the time is spent waiting for ...

This study investigatesvariability in English yes/no questions as well as the commonalities among yes/no question variants produced by members of two different varieties of English: Canadian English native speakers and Iranian EFL learners.Further, it probes the role of gender in theEnglish yes/no question variants produced by Canadian English native speakers and those produced by Iranian EFL l...

OBJECTIVES To determine whether the mentoring scheme currently used has an impact on the training of senior house officers and also determine if they are willing to accept middle grade mentors. METHODS A questionnaire comprising 10 questions was sent to all the senior house officers employed in the emergency departments of two large inner city teaching hospitals and three large district hospi...

Data from eight experiments on semantic verification are presented. Two procedures were used, a standard reaction time procedure and a response signal procedure. Data from the response signal procedure showed that for false category-member statements (e.g., all birds are robins), there was an increasing tendency to respond yes early in processing, replaced later in processing by an increasing t...
