In many non-human species, learning retention decreases temporarily following training. This has led to the suggestion that these lapses reflect a fundamental component of memory formation. If so, transient memory lapses should also be prevalent in humans, and should occur for all types of learning. In line with these predictions, we report two…

Recent evidence has shown that eliciting confidence ratings can affect cognitive performance--a so-called reactivity effect. Several mechanisms have been proposed to account for reactivity, but currently there is only indirect evidence about why confidence ratings are reactive. Here, we explore the strategic changes in cognitive processes that…

This research comprises two studies investigating the impact of mood and cognitive stimulation on creativity, with a focus on the role of task type. The first study focused on idea generation, whereas the second explored slogan generation, revealing differing outcomes for distinct tasks. Positive and negative moods were induced through memory…

The purpose of this study was to examine the effect of a refutation text on conceptual knowledge of dyslexia among pre-professional undergraduate students in communication sciences and disorders (CSD). Undergraduate students (n = 60) majoring in CSD were randomly assigned to two groups. They completed a pre-test to evaluate their conceptual…

Prior research suggests that the effectiveness of retrieval practice may be moderated by response format: overt retrieval (e.g., typing a response) outperforms covert retrieval (e.g., mentally recalling a response) for complex materials like definitions, but both forms of retrieval are equally effective for simple materials like single words.…

Data reported from memory can be unreliable. A simple activity lets students experience this firsthand.

Although we cannot see or touch time, across many cultures, we use spatial representations to think about this abstract concept. Spatial representations of time are thought to support temporal concepts that might otherwise be difficult to represent and reason about, such as the temporal component of episodic memory. One common form of spatially…

This study compared physical and digital models of a scientific topic in order to determine representational competence, short- and long-term cognition, and the extent to which physical or digital interfaces enhance spatial ability. The DNA molecule was used as a representative spatial topic to investigate conceptual and spatial understanding.…

A major question for the study of learning and memory is how to tailor learning experiences to promote knowledge that generalizes to new situations. In two experiments, we used category learning as a representative domain to test two factors thought to influence the acquisition of conceptual knowledge: the number of training examples (set size)…

Reading is a fascinating cognitive process through which individuals perceive arbitrary symbols on a page and turn them into vivid mental representations of text. Most available evidence supports an embodied explanation for how readers are capable of such representations--they recruit supralinguistic brain regions in order to mentally simulate the…

Speakers often use gesture to demonstrate how to perform actions--for example, they might show how to open the top of a jar by making a twisting motion above the jar. Yet it is unclear whether listeners learn as much from seeing such gestures as they learn from seeing actions that physically change the position of objects (i.e., actually opening…

Metaphor generation is both a creative act and a means of learning. When learning a new concept, people often create a metaphor to connect the new concept to existing knowledge. Does the manner in which people generate a metaphor, via sudden insight (Aha! moment) or deliberate analysis, influence the quality of generation and subsequent learning…

The current experiment examined the effect of forewarning on children's (11 to 12 years of age) and adults' spontaneous false memory creation by presenting participants with semantically related word lists that are often used to elicit false memories (i.e., Deese-Roediger-McDermott (DRM) paradigm). The forewarning consisted of an explanation of…

The laboratory is a complex environment where the three levels of the chemistry triplet coincide. As the laboratory environment places a large demand on the working memory of students, cognitive load theory can address overload which causes barriers to learning. Breaking down barriers requires iterative phases of analysis/exploration,…

This dissertation investigates the interaction of developing extralinguistic cognitive systems with early language learning and processing through the case study of verb argument structure. The interaction of these systems with the linguistic system underpins fundamental theories of language learning and use: language does not exist in isolation.…
