The uneven distribution of knowledge within modern societies requires a reliance on sources (e.g., reference books, teachers, the Internet) in addition to own experience. Most scientific issues are far too complex to be understood in any depth by laypersons. Successful knowledge acquisition comprises the ability to vary the amount of sources used…

This article describes a project designed to extend sixth-form pupils looking to further their knowledge and skill base in physics. This project involves a quantitative analysis of the decaying amplitude of a metal plate oscillating in a strong magnetic field; the decay of the amplitude is used to make estimates of the strength of the magnetic…

Experimental data are analysed statistically to allow researchers to draw conclusions from a limited set of measurements. The hard fact is that researchers can never be certain that measurements from a sample will exactly reflect the properties of the entire group of possible candidates available to be studied (although using a sample is often the…

Automatics and Robotics subjects are always greatly improved when classroom teaching is supported by adequate laboratory courses and experiments following the "learning by doing" paradigm, which provides students a deep understanding of theoretical lessons. However, expensive equipment and limited time prevent teachers having sufficient…

The ability to design appropriate experiments in order to interrogate a research question is an important skill for any scientist. The present article describes an interactive lecture-based activity centred around a comparison of two contrasting approaches to investigation of the question "Can you smell fear?" A poorly designed…

We present two experiments exploring whether individuals would be persuaded to imitate the intentional action of an adult model whose actions suggest that the correct way to complete a task is with an inefficient tool. In Experiment 1, children ages 5-10 years and a group of adults watched an adult model reject an efficient tool in favor of one…

A miniature linguistic system was used to study acquisition of recombinative symbolic behavior. Three studies evaluated the teaching conditions of conditional discriminations with printed and spoken pseudowords that could potentially generate recombinative reading. Fifty-four college students across all studies learned to match 12 printed…

This study examined the effectiveness of providing instructional support for the self-regulation of a self-directed homework assignment. Across four parallel experiments, university students completed an online module on critical thinking. In Experiment 1, participants who were prompted on a broad spectrum of study strategies showed superior…

While many behavioural studies on refractory phenomena in lexical/semantic access have focused on the mechanisms involved in the oral production of names, comprehension tasks have been almost exclusively used in neuropsychological studies on brain damaged patients. We report the results of two experiments on healthy participants conducted by means…

Visual short-term memory (VSTM) research suggests that the adult capacity is limited to three or four multifeature object representations. Despite evidence supporting a developmental increase in capacity, it remains unclear what the unit of capacity is in children. The current study employed the change detection paradigm to investigate both the…

The authors investigated how children and adults evaluate the "niceness" of individuals who engage in resource distribution, with a focus on their sensitivity to the proportion of resources given. Across 3 experiments, subjects evaluated the niceness of a child who gave a quantity of pennies to another child. In Study 1 (N = 30), adults showed…

The rapid development in Internet technology and its big popularity has led some universities around the world to incorporate web-based learning in some of their programmes. The present paper introduces a comprehensive survey of the publications about using remote laboratories in electrical engineering education. Remote laboratories are web-based,…

It is well established that visual search becomes harder when the similarity between target and distractors is increased and the similarity between distractors is decreased. However, in models of visual search, similarity is typically treated as a static, time-invariant property of the relation between objects. Data from other perceptual tasks…

With attention and eye-movements humans orient to targets of interest. This orienting occurs faster when the same target repeats: priming of pop-out (PoP). While reaction times (RTs) can be important, PoP's real function could be to steer "where" to orient, a possibility underexposed in many current paradigms, as these predesignate a target to…

Change detection requires perceptual comparison and decision processes on different features of multiattribute objects. How relative salience between two feature-changes influences the processes has not been addressed. This study used the systems factorial technology to investigate the processes when detecting changes in a Gabor patch with visual…
