Social isolation, as one of the most stressful conditions for social animals including rats induces a wide range of destructive effects on behavioral functions. On the other hand, Crocin (active component of <em>Crocus sativa</em>) induces pro-cognitive and neuroprotective effects. In the present study, we aimed to investigate the effects of prolonged maternal social isolation (pre-gestational) and crocin treatment on cognitive and behavioral functions in both adolescent and adult offspring. Female adult rats (mothers) were socially isolated from PND 30 to PND 80 (50 days). The treatment was performed by intraperitoneal injections of crocin (10, 30, and 50 mg/kg) during PND 39–45 or PND 59–65 (7 consecutive days), in the rat offspring. Behavioral assessments were done when the offspring were on PND 45 (adolescent) or PND 65 (adult). The expression level of Glycogen synthase kinase-3 beta (GSK-3beta) in the hippocampus was measured using real-time PCR. The results showed maternal social isolation decreased locomotion and impaired memory in adolescents, and increased anxiety- and depressive-like behaviors and GSK-3beta level, and decreased pain threshold in both adolescents and adults. Crocin (30 and 50 mg/kg) restored or attenuated the effect of maternal social isolation on behavioral functions and GSK-3beta in adolescents and adults, with more effect in adolescents. In conclusion, we showed that crocin treatment can restore the destructive effects of maternal social isolation stress in the offspring, with stronger therapeutic effects in adolescents. Also, GSK-3beta downregulation may underlie the beneficial effects of crocin.</div></div>","PeriodicalId":47305,"journal":{"name":"Learning and Motivation","volume":"88 ","pages":"Article 102060"},"PeriodicalIF":1.7,"publicationDate":"2024-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142535352","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study employs a comprehensive meta-analysis and structural equation modeling with path models to reassess the impacts of these influential factors on academic achievement. Specifically, it aims to 1. examine the directional effects of perceived feedback on self-efficacy; 2. investigate the role of self-efficacy in mediating the relationship between feedback and learning motivation; and 3. assess the direct and indirect effects of feedback, self-efficacy, and learning motivation on academic performance. Data is collected from various educational contexts to ensure a broad representation of learners' experiences. The analysis also evaluates the viability of mean imputation for handling missing values in two-stage structural equation modeling. The findings show that feedback from formative assessments strongly predict academic success as it has both direct and indirect effects on performance. Self-efficacy and learning motivation also play a key role in explaining differences in academic outcomes.

Although there is evidence that this effect could be reproduced in rats (e.g., response-independent noise disrupts rats’ performance on schedules of reinforcement), no explicit attempt has been reported to date. The present study tested the generality of the disruptive effect of aversive contexts in rats’ impulsive choice. To emulate the procedures implemented with humans, response-independent (Random-Time 60 s) mild-intensity footshocks (.25 mA) were incorporated into a systematic replication of Green and Estle’s (2003) task designed to study preference reversal phenomena (i.e., SS preference changes to LL with the addition of delays before both the SS and LL alternatives). In doing so, we explored the effects of an aversive context on preference reversal, which also have not been reported to date. Male Wistar rats (16) were exposed to three different conditions; eight of them experienced shocks throughout the study. During an initial delay configuration condition (SS = 2 pellets after 0.5-s; LL = 4 pellets after 6 s), responding of non-shocked rats showed an increase from indifference (∼ 50 % LL) towards preference for the LL option (∼ 75 % or higher LL responses), whereas responding of shocked rats did not deviate from indifference. Next, delays were added to the LL reinforcer until SS preference was individually established (+6 s, +9 s, +15 s, etc.). The behavior of non-shocked rats seemed more affected by the added delays, e.g., they reached SS preference with less added delays. Preference-reversal conditions consisted of adding 5-s, 15-s, and 25-s delays to both SS and LL alternatives. Shocked rats showed a more robust and consistent preference reversal effect than non-shocked rats. Research on manipulations that reduce impulsive choice suggests that similar processes could explain the disruptive effects of aversive contexts and the effects of interventions; namely, aversiveness of delays and discrimination of contingent relations between temporally distant events. The results of the present study are discussed in that framework, focusing on covariations between rats’ choice patterns across the different delay configurations and the distribution of shocks pre- and post- reinforcement delivery.</p></div>","PeriodicalId":47305,"journal":{"name":"Learning and Motivation","volume":"88 ","pages":"Article 102048"},"PeriodicalIF":1.7,"publicationDate":"2024-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142241914","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
