Parental Stress Provoked by Short-Term School Closures During the Second COVID-19 Lockdown.

Governments of numerous countries implemented school closures to contain the COVID-19 pandemic. Several investigations have shown the negative impact of social-distancing policies and school closures on children worldwide. Recently, research also demonstrated adverse effects on adults' well-being. The development of children is strongly affected by their parent's emotional state. The present study aimed to examine parental stress levels caused by a short period of homeschooling in December 2020 in Germany. A structured survey was set up and distributed randomly via social media and parent associations. We observed a significant increase in stress and concerns. Family conflicts significantly increased, social isolation was feared, and powerlessness and helplessness ascended. Risk factors were parental education levels, parental working time, and teaching features like the frequency of feedback, correction, and accessibility.

Far-right boundary construction towards the "other": Visual communication of Danish People's Party on social media.

This paper explores how images are used in online far-right political communication to create distinct groups of "otherness." Focusing on the Danish People's Party, we look at how symbolic boundaries are constructed through images to emphasize an exclusive conception of the nation and its citizens, who need protection from the threatening "others." In order to understand the global rise of the far right, scholars of social movements and digital media have called for new research on how visual images serve the mainstreaming of extremist and nationalist beliefs online. We look at images communicated by the Danish People's Party on their Facebook page, exploring how digital images visually communicate the party's slogan of "Safety and trust" (in Danish: "Tryghed og tillid"). With a focus on boundary construction, we present a multimodal visual analysis of 1120 images posted by the party from 2012 to 2020. The data shows how the party constructs an imaginary of Danishness through an exclusionary impermeable boundary construction of a trusted in-group's values and traditions in opposition to culturally distinct "others."

Embodiment: I sat, I felt, I performed - Posture effects on mood and cognitive performance.

Previous embodiment findings indicate a relationship between physical posture and mood states, suggesting upright postures induce positive mood states. Findings also showed a relationship between moods and cognitive performance. While positive mood states were found to be related to increased processing speed, negative mood states were associated with higher processing accuracy in cognitive task performance. This implies that posture may affect the aforementioned sub-aspects of cognitive performance via mood states. Additionally, most studies on posture effects rely on explicit posture manipulation. With that in mind, our research explores the effects of implicitly manipulated postures on processing speed and accuracy and whether these effects are mediated by general mood. The results revealed that subjects in our sample (N = 82, M = 23.09years) who adopted an upright posture showed a more positive general mood (d = 0.50) and higher processing speed (d = 0.42) compared to those in stooped postures. Surprisingly, no differences in processing accuracy were found. There was no evidence of the proposed mediation in our data.

Protest symbols.

Recent research on social movements have shown the significant role protest symbols play in mobilizing action and constructing a shared identity for a group pressing for social change. The present article gives an overview of crowd and social movement theories that focus on how symbols form and maintain groups. Borrowing from cultural psychology and social representations theory it explores how symbols are created and the meaning making processes around them within larger groups. The article unpacks two key functions of symbols within protest: first as a motivating trigger for protest action, and second as a unifying symbol for group identity and solidarity. It concludes with a discussion of how focusing on protest symbols could inform future social psychological research.

Levo-tetrahydropalmatine attenuates cocaine self-administration and cocaine-induced reinstatement in rats.

RATIONALE: Levo-tetrahydropalmatine (l-THP) is an alkaloid constituent of plants from the botanical genera Corydalis and Stephania and is contained in many traditional Chinese herbal preparations. In addition to its low-affinity antagonism of D2 dopamine (DA) receptors, we report that l-THP functions as a higher-affinity antagonist at D1 DA receptors and interacts with D3 DA receptors, suggesting that it may be effective for the treatment of drug addiction. Accordingly, l-THP has been reported to reduce heroin craving and relapse in recovering addicts. OBJECTIVE: This study investigated the effects of l-THP (3.75, 7.5, and 15.0 mg/kg, i.p.) on cocaine self-administration (SA) and cocaine-induced reinstatement. MATERIALS AND METHODS: Rats were trained to self-administer cocaine and food by pressing separate response levers during sessions consisting of a multiple schedule of alternating 30-min FR4 cocaine and 15-min FR4 food reinforcement. During the cocaine components of each session, the available cocaine dose varied such that rats had access to low and high dose ranges in varying sequence on alternating days. After SA, cocaine-reinforced responding was extinguished, and effects of l-THP on cocaine-induced reinstatement (10 mg/kg, i.p.) were examined. RESULTS: l-THP produced a rightward and downward shift in the dose-response curve for cocaine SA and attenuated cocaine-induced reinstatement. l-THP also reduced food-reinforced responding and locomotor activity. However, reductions in cocaine SA were found at doses that failed to alter food-reinforced responding, and significant effects were not observed on food responding during reinstatement. CONCLUSIONS: These findings suggest that l-THP is potentially useful for treating cocaine addiction.
