Description
Collaborative learning is a potential technique for teachers to use to meet the diverse learning needs of the students in their classrooms. Previous studies have investigated the contexts in which the benefits of collaborative learning show greater presence. The most important factor found was the quality of the interactions. Studies have suggested that high achieving students are capable of improving the quality of interactions. This bears the question if prior knowledge plays an influence in the learning outcome of students in collaborative learning. Results show that high prior knowledge students do not face a detriment in having low prior knowledge students as a partner comparing to having another high prior knowledge student and that low prior knowledge students show significantly higher learning outcome when partnered with a high prior knowledge partner than with another low prior knowledge student. It is therefore likely that having a high prior knowledge student within a dyad improves the quality of interaction, resulting in greater learning outcome through collaborative learning.

Description
Language comprehension is an essential skill in many aspects of life, yet some children still struggle with oral comprehension. This study examined the effectiveness of an intervention to improve the listening skills and comprehension of 4 and 5-year olds. This intervention is based on principles of embodied cognition, namely that language comprehension requires a simulation (or imagination) of what the language is about. Thus, children in the intervention condition moved pictures on an iPad to simulate the stories they were hearing. Children in the control condition saw the pictures, but did not move them. To identify the effectiveness of this simulation training, we analyzed scores on a comprehension test, and changes in motor cortex activity while listening. If the intervention increases simulation, then compared to the control, a) children given the intervention should perform better on the comprehension test, and b) those children should show greater activity in their motor cortices while listening. Furthermore, the change in motor cortex activity should statistically mediate the change in comprehension. Our results showed a significant positive correlation (.79) in the EMBRACE group (but not in the control) between the change in mu suppression before and after the intervention and the change in comprehension questions before and after the intervention. This correlation suggests that children can be taught to use their motor cortices while listening, and supports our hypothesis that embodied language theories, such as simulation are useful for enhancing comprehension.

Description
Working memory is the cognitive system responsible for storing and maintaining information in short-term memory and retrieving cues from long-term memory. Working memory capacity (WMC) is needed for goal maintenance and to ignore task-irrelevant stimuli (Engle & Kane, 2003). Emotions are one type of task-irrelevant stimuli that could distract an individual from a task (Smallwood, Fitzgerald, Miles, & Phillips, 2009). There are studies that show there is a relation between emotions and working memory capacity. The direction of this relationship, though, is unclear (Kensinger, 2009). In this study, emotions served as a distractor and task performance was examined for differences in the effect of emotion depending on participants' working memory capacity. The participants watched a mood induction video, then were told to complete a complex-span working memory task. The mood induction was successful- participants watching the negative emotional video were in a less positive mood after watching the video than the participants that watched a neutral video. However, the results of the complex-span working memory task showed no significant difference in the results between participants in the negative versus neutral mood. These results may provide support to an alternative hypothesis: cognitive tasks can diminish the effects of emotions (Dillen, Heslenfeld, & Koole, 2009).

Description
An important facet of daily memory function is prospective memory, which is one’s ability to complete established intentions in the appropriate temporal and spatial context. Many factors contribute to impairments in prospective memory, such as limited cognitive resources or aging. A factor that has been subject to recent investigation is how cannabis use may have an impact on the mechanisms that contribute to prospective memory. Cannabis use has been on the rise across the world, and in the United States more states are pushing to legalize its recreational use, if they haven’t already. As this substance becomes more easily accessible, akin to alcohol use, the necessity to investigate its potential consequences on cognition is needed now more than ever. Prospective memory is an appropriate measure of cannabis-induced deficits due to the wide literature looking at neural correlates of the component mechanisms that contribute to successful prospective memory, attentional and memory processes. The current study employed two experiments to measure this argued claim. Experiment 1 replicated well-defined effects from the prospective memory literature by measuring task accuracy (memory), response times (attention), and pupillary dynamics (attention). Informed by the research looking at the brain regions suspected of experiencing the most functional impairment, Experiment 2 aimed to extend these findings with a sample of participants following acute cannabis administration, however, results indicated cannabis group performance was similar in accuracy and showed faster mean latencies to that of the control group.

Description
Individuals encounter problems daily wherein varying numbers of constraints require delimitation of memory to target goal-satisfying information. Multiply-constrained problems, such as compound remote associates, are commonly used to study this type of problem solving. Since their development, multiply-constrained problems have been theoretically and empirically related to creative thinking, analytical problem solving, insight problem solving, intelligence, and a multitude of other cognitive abilities. Critically, in order to correctly solve a multiply-constrained problem the solver must have the solution available in memory and be able to target and access to that information. Experiment 1 determined that the cue – target relationship affects the likelihood that a problem is solved. Moreover, Experiment 2 identified that the association between cues and targets predicted inter- & intra-individual differences in multiply-constrained problem solving. Lastly, Experiment 3 found monetary incentives failed to improve problem solving performance likely due to knowledge serving as a limiting factor on performance. Additionally, problem solvers were shown to be able to reliably assess the likelihood they would solve a problem. Taken together all three studies demonstrated the importance of knowledge & knowledge structures on problem solving performance.
