Description
This study investigates the effectiveness of the use of Concept-Based Instruction (CBI) to facilitate the acquisition of Spanish mood distinctions by second semester second language learners of Spanish. The study focuses on the development of Spanish mood choice and the types of explanations (Rule-of-Thumb vs. Concept-based) used by five students before and after being exposed to Concept-Based Instruction regarding the choice of Spanish mood following various modalities .The students in this study were presented with a pedagogical treatment on Spanish mood choice that included general theoretical concepts based on Gal'perin's (1969, 1992) didactic models and acts of verbalization, which form part of a Concept-Based pedagogical approach. In order to ascertain the effectiveness of the use of concept-based tools to promote the ability to use Spanish mood appropriately over time, a pre and post-test was administered to the group in which students were asked to respond to prompts containing modalities that elicit the indicative and subjunctive moods, indicate their level of confidence in their response, and verbalize in writing a reason for their choice. The development of these abilities in learners exposed to CBI was assessed by comparing pre and post-test scores examining both forms and explanations for the indicative and subjunctive modality prompts given. Results showed that students continued to rely on Rule-of-Thumb explanations of mood choice but they did expand their use of conceptually-based reasoning. Although the quantitative and qualitative analyses of the results indicate that most students did improve their ability to make appropriate mood choices (forms and explanations) after the CBI treatment, the increased use of conceptually-based explanations for their mood choices led to both correct and incorrect responses.

Description
This study examines the effect that the modality (volition, doubt, emotion, belief, knowledge, etc.) of matrix noun clauses has on the ability of intermediate (second-year) Spanish L2 students (n=56) to properly produce the subjunctive and indicative moods, the relative order in which students tend to most accurately produce the subjunctive in response to the modalities of volition, doubt, and emotion, and students' level of syntactic ability and mood development. Each participant took a test consisting of twenty questions containing various modalities intended to elicit either the subjunctive or indicative mood. Participants also filled out a questionnaire that was designed to ascertain the participants' level of formal and informal experience with Spanish. The results of this study show that a) when the subjunctive was the target response most participants favored the unmarked indicative mood significantly more than the marked subjunctive mood, b) students most accurately produced the subjunctive to the modality of volition (VL), followed by doubt (DT), and emotion (EM), which is consistent with Collentine's study, and c) students were able to process complex syntax when producing the unmarked indicative mood but not when they were prompted to produce the marked subjunctive mood. The results of this study show that pedagogical expectations regarding the acquisition of the subjunctive mood by second-year Spanish students may be unrealistic as these students were operating somewhere between the pre-syntactic and syntactic stages.

Description
With obesity and metabolic diseases reaching epidemic levels, it is important to find ways to increase physical activity and improve diet. Previous studies have shown that improvements in mood can increase desire to perform physical activity, and that vitamin C intake is linked to improvements in mood. Based on this, two hypotheses were formed and tested to investigate the effect on physical activity levels and mood states from vitamin C supplementation at a dose of one gram per day in the form of a novel functional food. Thirty-one college students or faculty at Arizona State University were screened from a pool of applicants and placed into either a vitamin C or placebo group; all participants received the novel functional food to eat daily for four weeks. Serum levels of vitamin C, weight, height, BMI, body fat percentage, mood, and physical activity were measured before and after the functional food intervention. Vitamin C changed significantly through the course of the study in the experimental group. Baseline data for participants showed a positive correlation between vitamin C status and vigor, and a negative correlation between vitamin C status and weight and BMI. Physical activity was not related to vitamin C status, according to baseline data, and it did not significantly change over the course of the study. The results indicate that variance in BMI can be attributed to vitamin C status, but the study should be refined and tested again.

Description
Autism spectrum disorder (ASD) is highly comorbid with mood disorders, such as depression and anxiety. Previous research suggests difficulties in emotion regulation to be concordant with experiencing these comorbid symptoms. Understanding the neural correlates of emotion regulation in ASD and relationships with mood symptoms could provide insights for effective treatments. We employed an existing functional MRI paradigm to assess neural activation during an emotional regulation task in adults with ASD, and correlate activated regions with self-reported measures of depression and anxiety. We found the following regions to be significantly associated with emotion regulation (family-wise error corrected p<0.05): the bilateral insula, anterior cingulate, middle cingulate, precentral gyrus, angular gyrus, left dorsolateral PFC, right caudate/putamen, and left medial PFC. We found anxiety, but not depression, symptoms were negatively correlated with activation in the anterior cingulate, left insula, and left putamen, and showed a moderate relationship to the amygdala. These results expand current understanding of ASD and emotion regulation and suggest targets for future clinical intervention.
