“…One possibility is that participants learned new PAs three times in their study, which resulted in increased activation in the hippocampus for the schema‐IC condition, leading to comparable hippocampal activation between conditions. Studies have shown that hippocampal activation increases via repetitive learning (Zhan, Guo, Chen, & Yang, ; for a review, see Kim, ). As proposed by van Kesteren et al (), schema‐incongruent associations could be a part of schema if they were reactivated repeatedly.…”

When new information is relevant to prior knowledge or schema, it can be learned and remembered better. Rodent studies have suggested that the hippocampus and ventromedial prefrontal cortex (vmPFC) are important for processing schema‐related information. However, there are inconsistent findings from human studies on the involvement of the hippocampus and its interaction with the vmPFC in schema‐related memory retrieval. To address these issues, we used a human analog of the rodent spatial schema task to compare brain activity during immediate retrieval of paired associations (PAs) in schema‐consistent and schema‐inconsistent conditions. The results showed that the anterior hippocampus was more involved in retrieving PAs in the schema‐consistent condition than in the schema‐inconsistent condition. Connectivity analyses showed that the anterior hippocampus had stronger coupling with the vmPFC when the participants retrieved newly learned PAs successfully in the schema‐consistent (vs. schema‐inconsistent) condition, whereas the coupling of the posterior hippocampus with the vmPFC showed the opposite. Taken together, the results shed light on how the long axis of the hippocampus and vmPFC interact to serve memory retrieval via different networks that differ by schema condition.

BACKGROUND: Obesity is a global health problem of immense magnitude. Increased awareness and knowledge about obesity in health-care providers are essential to addressing this global issue. The aim of the present study was to assess the baseline knowledge on obesity of university students in health-related programs and evaluate the effectiveness of modified physiology laboratory (MPL) sessions in enhancing the awareness of obesity of these students by repeated exposure to physiological differences between normal weight (NW) and overweight or obese (OW/OB) individuals. MATERIALS AND METHODS: It was a quasi-experimental study in which three regular physiology laboratory exercises were modified (MPL) to address different aspects of obesity. A total of 319 students (181 male and 138 female) from health-related colleges taking the physiology course during academic session 2011–2012 were included in the study. A questionnaire on obesity served as a measure of prior knowledge and improvement of evolution of student knowledge. The questionnaire was administered thrice: Beginning of the first MPL session (pretest), at the end of the second session of the first MPL (posttest-1), and the end of second session of the final MPL (posttest-2). Correct knowledge (CK), perceived knowledge (PK), and accuracy of knowledge (KA) were evaluated. Students gathered and analyzed physiological data in these sessions to explore the differences between NW and OW/OB subjects. RESULTS: The students' level of PK on obesity was high, but KA was low in pretest. The three knowledge indices improved significantly ( P <0.001) from pretest (PK = 77.2%; KA = 52.8%; CK = 40.5%) to posttest 1 (PK = 93.5%; KA = 70.1%; CK = 65.9%). However, from posttest 1 to posttest 2, only small but significant increments were observed in CK (10.5%) and KA (8.7%). CONCLUSION: The awareness and knowledge on obesity of health-related undergraduate university students at baseline were low, but significantly improved after MPLs. The students' knowledge did not only increase but also improved in accuracy. This increase in awareness and knowledge of obesity is expected to directly impact on the students' lifestyles and boost their confidence to counsel others on obesity.

The purpose of this study was to evaluate a mobile-based maternal feeding education program for overweight prevention in infants based on breastfeeding attitude, breastfeeding self-efficacy, breastfeeding duration, recognition of hunger and satiety cues of infants, and knowledge regarding providing solids foods. Methods: A nonequivalent control group pretest-posttest design was used for the study. Participants included 15 primiparas in the experimental group and 14 primiparas in the control group in all the follow-up tests. Using self-reported questionnaires in electronic format, data were collected four times (before the intervention, 1 month after childbirth, 3 months after childbirth, and 6 months after childbirth). Using SPSS 24 version, independent t-test and repeated-measures analysis of variance were used to test the effects of the mobile-based maternal feeding education program. Results: The experimental group showed significantly more positive breastfeeding attitude (F ¼ 5.28, p ¼ .008), higher breastfeeding self-efficacy (F ¼ 3.50, p ¼ .041), and increased breastfeeding duration (t ¼ À2.09, p ¼ .046) than the control group. In addition, the experimental group showed significantly improved knowledge regarding providing solid foods to the infants (F ¼ 4.86, p ¼ .009) in comparison with the control group. However, for education on recognizing hunger and satiety cues of infants, the mobile-based maternal feeding education program was not effective (F ¼ 0.23, p ¼ .878). Conclusion:According to the results of this study, the mobile-based maternal feeding education program has the potential to contribute to overweight prevention in infants.
