In the task-switching literature, it has frequently been demonstrated that although advance task preparation reduces the switch cost, it never really eliminates the switch cost. This remaining residual switch cost received much attention, and it has been argued that advance preparation is restricted in nature. In the present study, the role of…

Two experiments were conducted to investigate discourse representation in the two cerebral hemispheres as a function of reading skill. We used a lateralized visual-field procedure to compare left hemisphere (LH) and right hemisphere (RH) sensitivity to different discourse relations in readers with varying skill levels. In Experiment 1, we…

The authors report on a series of 5 experiments in which 462 5- to 10-year-old children and 109 adults were required to copy geometric figures either with no constraints or following prior exposure to primes consisting of different parsings of the figures. The analysis focused on the graphic strategies adopted by the participants to copy the…

The goal of this study is to develop a virtual farm for educational applications. Users can play the role of a farmer by planting vegetables and raising poultry on the virtual farm to observe their growth through online learning activities. The virtual farm possesses educational and entertaining functions, and it is designed by simulating the real…

This project was designed to test Mayer's multimedia theory in an elementary school to improve students' mathematics learning for low-income children. The study designed and developed two multimedia mathematics experiments in 3rd grade: 9's multiplication experiment and geometric solids experiment. The two experimental lessons were implemented in…

Linguistic prominence is defined as words or syllables perceived auditorily as standing out from their environment. It is explored through changes in pitch, duration and loudness. In this study, phonetic realization and perception of prominence among lexical tones in Mandarin Chinese was investigated in two experiments. Experiment 1 explored…

This paper seeks to foster a discussion on whether experiments with robots can inform theory in infant motor development and specifically (1) how the interactions among the parts of a system, including the nervous and musculoskeletal systems and the forces acting on the body, induce organizational changes in the whole, and (2) how exploratory…

The aim of this study was to test the hypothesis according to which theory of mind competence was a prerequisite to ambiguous idioms understanding. We hypothesized that the child needs to understand that the literal interpretation could be a false world representation, a false belief, and that the speaker's intention is to mean something else, to…

The theory of syntactic bootstrapping proposes that children can use syntax to infer the meanings of words. This paper presents experimental evidence that children are also able to use word inflections to infer word reference. Twenty-four- and 30-month-olds were tested in a preferential looking experiment. Children were shown a pair of novel…

The phonetic context in which word-medial flaps occur (in contrast to [t[superscript h]]) in American English is explored. The analysis focuses on stress placement, following phone, and syllabification. In Experiment 1, subjects provided their preference for [t[superscript h]] or [flapped t] in bisyllabic nonce words. Consistent with previous…

High diversity of microorganisms in the soil matrix has been the focus of extensive research in the fields of soil biology and microbial ecology, and is a key concept that students in the environmental or biological sciences should understand. Two activities to demonstrate diversity and highlight the challenges faced in studying soil microbial…

In 2 experiments, the authors investigated a potential interaction involving the processing of concurrent feedback using design features from the specificity of practice literature and the processing of terminal feedback using a manipulation from the guidance hypothesis literature. In Experiment 1, participants produced (198 trials)…

Recent articles in "Teaching of Psychology" have endorsed the classroom use of various mnemonic techniques. Yet a degree of mnemonophobia (i.e., fear of using mnemonics) may persist in the minds of some "ToP" readers due to various lingering misconceptions. In this regard, we conducted 3 practical experiments with college students using the…

An important aspect of teaching biology is to expose students to the concept of biodiversity. For this purpose, bacteria are excellent examples. The advanced placement (AP) biology class at Cedar Shoals High School in Athens, Georgia, learned how to explore bacterial biodiversity using molecular fingerprinting. They collected marine water samples,…

In this work we show how specific challenges related to sustainable development can be integrated into chemical engineering education by introducing an environmental management system in the laboratory where the students perform their experimental lessons. It is shown how the system has been developed and implemented in the laboratory, what role…
