In a recent article, Schlinger (2008) marked the 50th anniversary of the publication of Skinner's "Verbal Behavior" (1957) by considering its impact on the field of behaviorism and research on verbal behavior. In the present article, we comment on Schlinger's conclusions regarding the impact of the book and highlight the extensions and…

Previous reports using stimulus intensity changes to disrupt temporal discrimination have shown shifts in the psychophysical curve for time, while studies using other disruptors have shown a flattening of the curve. The current study investigated the impact of increases and decreases in stimulus intensity on temporal discrimination in pigeons, to…

Two experiments were conducted to determine whether participants have source memory for test stimuli that they cannot identify. Using a paradigm developed to investigate the phenomenon of "recognition without identification" (Peynircioglu, 1990), we found that even when participants could not identify a previously studied item, they…

How do fifth-grade students in a gifted class construct understandings of the opposite sex? In what ways do these constructions manifest in the visual texts created in literacy and language arts classrooms? This qualitative study integrated visual arts to understand how fifth-grade gifted students represented and perceived gender roles. Using…

This paper presents a 2007 study that was conducted amongst 147 young anglophone, francophone and allophone Montrealers in order to shed light on their attitudes towards English and French in terms of status and solidarity. The study made use of both a questionnaire and a matched-guise experiment. The findings indicate that while a certain amount…

During the second year of life, infants develop a preference to attach novel labels to novel objects. This behavior is commonly known as "mutual exclusivity" (Markman, 1989). In an intermodal preferential looking experiment with 19.5- and 22.5-month-olds, stimulus repetition was critical for observing mutual exclusivity. On the first…

Assessing children's learning is a key part of teaching. In all curriculum areas it is used for informing planning of future learning experiences and assessing pupil progress. Specifically in science, it identifies knowledge and understanding of scientific concepts, reasoning, and practical skill development. There are various ways to assess,…

Memory is thought to be sparsely encoded throughout multiple brain regions forming unique memory trace. Although evidence has established that the amygdala is a key brain site for memory storage and retrieval of auditory conditioned fear memory, it remains elusive whether the auditory brain regions may be involved in fear memory storage or…

Despite the fact that hemispheric asymmetry of attention has been widely studied, a clear picture of this complex phenomenon is still lacking. The aim of the present study was to provide an efficient and reliable measurement of potential hemispheric asymmetries of three attentional networks, i.e. alerting, orienting and executive attention.…

This longitudinal study examined the influence of stimulus material on attention and expectation learning in the visual expectation paradigm. Female faces were used as attention-attracting stimuli, and non-meaningful visual stimuli of comparable complexity (Greebles) were used as low attention-attracting stimuli. Expectation learning performance…

When people describe motion events, their path expressions are biased toward inclusion of goal paths (e.g., into the house) and omission of source paths (e.g., out of the house). In this paper, we explored whether this asymmetry has its origins in people's non-linguistic representations of events. In three experiments, 4-year-old children and…

The role of frontal cortex in selective attention to visual distractors was examined in an attentional capture task in which participants searched for a unique shape in the presence or absence of an additional colour singleton distractor. The presence of the additional singleton was associated with slower behavioural responses to the shape target,…

Bortoloti and de Rose (2009) found evidence that the level of functional transfer is higher in equivalence classes generated by delayed matching to sample (DMTS) than in classes generated by simultaneous matching (SMTS). We attempted to replicate these findings with the Implicit Relational Assessment Procedure (IRAP). Two experimental groups…

Perez-Gonzalez, Herszlikowicz, and Williams (2008) demonstrated the emergence of novel intraverbal responses following the training of several intraverbals. The present study replicated and extended that study by separating two training conditions that were combined in the previous study. Nine typically developing children ages 6-7 years were…

Immediate serial recall is seriously disrupted by to-be-ignored sound. According to the embedded-processes model, auditory distractors elicit attentional orienting that draws processing resources away from the recall task. The model predicts that interference should be attenuated after repeated exposure to the auditory distractors. Previous…
