This paper explores peer-peer interactions of children using a spot-the-differences task in an EFL context in Hungary. The children were asked to practise with several sets of similar spot-the-differences tasks and the analysis focuses on the observable changes from the first to the last repetition. After the task performances were recorded, the…

This paper reports an example of a situation in which university students had to solve geometrical problems presented to them dynamically using the interactive computerized environment of the "MicroWorlds Project Builder". In the process of the problem solving, the students used ten different solution strategies. The unsuccessful…

Nine graduate students (teacher-researchers) with an average of 6 years teaching experience (1-15 years) participated in action research to examine the influence of teacher-chosen visual aids (pictures) on children's writing. A total of 165 elementary students participated in the two phases of the research project: 83 boys and 82 girls in…

Behavioral pharmacology is a maturing science that has made significant contributions to the study of drug effects on behavior, especially in the domain of drug-behavior interactions. Less appreciated is that research in behavioral pharmacology can have, and has had, implications for the experimental analysis of behavior, especially its…

Two groups of three students with moderate mental retardation were instructed using group procedures to compare static picture and video prompting simulation strategies. An alternating treatments design was used to compare individual student task acquisition and maintenance performances of purchasing and banking skills. The results indicated that…

Conjunction errors occur when participants incorrectly identify as "old" novel test stimuli created by recombining parts of two study stimuli (parent items). Prior studies have reported that the conjunction error rate is higher when parent items are studied together than when they are studied apart (a parent proximity effect). In several…

Although the veridicality of unconscious perception is increasingly accepted, core issues remain unresolved [Jack, A., & Shallice, T. (2001). Introspective physicalism as an approach to the science of consciousness. "Cognition, 79," 161-196], and sharp disagreement persists regarding fundamental methodological and theoretical issues. The most…

The episodic buffer component of working memory is assumed to play a role in the binding of features into chunks. A series of experiments compared memory for arrays of colors or shapes with memory for bound combinations of these features. Demanding concurrent verbal tasks were used to investigate the role of general attentional processes,…

Evoked potential studies have demonstrated that musicians have the ability to distinguish musical sounds preattentively and automatically at the temporal, spectral, and spatial levels in more detail. It is however not known whether there is a difference in the early processes of auditory data processing of musicians. The most emphasized and…

Numerous instructional techniques have been used to teach sight word reading skills to individuals with developmental disabilities. The results of research incorporating paired associate instruction, in which familiar pictures are paired with unknown print stimuli, suggest that pictures ''block'' (i.e., interfere with) learners' ability to…

Right hemispheric dominance in unconscious emotional processing has been suggested, but remains controversial. This issue was investigated using the subliminal affective priming paradigm combined with unilateral visual presentation in 40 normal subjects. In either left or right visual fields, angry facial expressions, happy facial expressions, or…

In order to teach individuals with developmental disabilities to request stimuli they are motivated to obtain (mand), it is often necessary to initially deliver the item requested immediately and frequently. This may result in an undesirably high rate of mands that is impractical to maintain. The purpose of the current investigation was to extend…

Projective techniques continue to be widely used by school psychologists despite frequent criticisms of their use. This article reviews contemporary validity issues in the use of projective techniques with children and adolescents, including incremental validity, treatment validity, and problems associated with professional judgment and…

Understanding how memory works is important for success in school, for "all" students. One way for teachers to help students with disabilities learn about memory is to use picture books and then learn strategies. Picture books are useful for students with disabilities because these resources have moved beyond a means to scaffold early literacy…

The assessment of individual differences in facial expression recognition is normally required to address two major issues: (1) high agreement level (ceiling effect) and (2) differential difficulty levels across emotions. We propose a new assessment method designed to quantify individual differences in the recognition of the six basic emotions,…
