The honey bee Apis mellifera is a major insect model for studying visual cognition. Free-flying honey bees learn to associate different visual cues with a sucrose reward and may deploy sophisticated cognitive strategies to this end. Yet, the neural bases of these capacities cannot be studied in flying insects. Conversely, immobilized bees are accessible to neurobiological investigation but training them to respond appetitively to visual stimuli paired with sucrose reward is difficult. Here we succeeded in coupling visual conditioning in harnessed bees with pharmacological analyses on the role of octopamine (OA), dopamine (DA) and serotonin (5-HT) in visual learning...

AIM: Neuroinflammation is a critical pathogenic mechanism of most neurodegenerative disorders especially, Alzheimer's disease (AD). Lipopolysaccharides (LPS) are known to induce neuroinflammation which is evident from significant upsurge of pro-inflammatory mediators in in vitro BV-2 microglial cells and in vivo animal models. In present study, we investigated anti-neuroinflammatory properties of deoxyelephantopin (DET) isolated from Elephantopus scaber in LPS-induced neuroinflammatory rat model...

PURPOSE: HIV/AIDS disproportionately affects young gay, bisexual, and other men who have sex with men (Y-GBMSM). Resilience remains understudied among Y-GBMSM living with HIV, but represents a potentially important framework for improving HIV-related outcomes in this population. We sought to explore cognitive and behavioral dimensions of resilience and their correlates among Y-GBMSM to gain insights to inform future interventions. METHODS: Our study sample consisted of 200 Y-GBMSM living with HIV enrolled in a multisite study of the Adolescent Medicine Trials Network for HIV/AIDS Interventions (ATN)...

Psychologists have studied small-group and team effectiveness for decades, and although there has been considerable progress, there remain significant challenges. Meta-analyses and systematic research have provided solid evidence for core team cognitive, motivational, affective, and behavioral processes that contribute to team effectiveness and empirical support for interventions that enhance team processes (e.g., team design, composition, training, and leadership); there has been substantial evidence for a science of team effectiveness...

The ability to recognize novel situations is among the most fascinating and vital of the brain functions. A hypothesis posits that encoding of novelty is prompted by failures in expectancy, according to computation matching incoming information with stored events. Thus, unexpected changes in context are detected within the hippocampus and transferred to downstream structures, eliciting the arousal of the dopamine system. Nevertheless, the precise locus of detection is a matter of debate. The dorsal CA1 hippocampus (dCA1) appears as an ideal candidate for operating a mismatch computation and discriminating the occurrence of diverse stimuli within the same environment...

BACKGROUND: Identifying scalable strategies for assessing fidelity is a key challenge in implementation science. However, for psychosocial interventions, the existing, reliable ways to test treatment fidelity quality are often labor intensive, and less burdensome strategies may not reflect actual clinical practice. Cognitive behavioral therapies (CBTs) provide clinicians with a set of effective core elements to help treat a multitude of disorders, which, evidence suggests, need to be delivered with fidelity to maximize potential client impact...

Background: Misuse of antibiotics can be described as a failure to complete treatment, skipping of the doses and reuse of leftover medicines and overuse of antibiotics. Health education interventions are expected to enhance awareness and general belief on rational antibiotics use. Therefore, the study aimed to determine the efficacy of social cognitive theory (SCT)-based self-care intervention for rational antibiotic use. Methods: This randomized trial was conducted in a sample of 260 adults...

BACKGROUND: Interest in social cognition in bipolar disorder (BD) has increased considerably over the past decade, with studies highlighting major impairments, especially in mental state reasoning, even during euthymia. A causal relationship between social cognition deficits and social functioning has already been established in individuals with schizophrenia, but there is still little information about links between social cognition and social functioning in BD. Our aim was therefore to review the relationship between functional outcome and social cognition in patients with BD...

Although numerous studies have investigated emotion regulation, the physiological responses and neural substrates of positive emotion regulation remain unclear. To address this question, we explored the effect of reappraisal on subjective experience, zygomatic electromyography (zEMG) response, and blood oxygen level response, using the same materials across three independent experiments. Behaviorally, up-regulating positive emotion increased the valence, arousal, and zEMG response, whereas down-regulating positive emotion decreased the valence, but not arousal or the zEMG response...

Alterations in adult neurogenesis have been regarded as a major cause of cognitive impairment in Alzheimer's disease (AD). The underlying mechanism of neurogenesis deficiency in AD remains unclear. In this study, we reported that Integrin-linked Kinase (ILK) protein levels and phosphorylation were significantly decreased in the hippocampus of APP/PS1 mice. Increased ILK expression of dentate gyrus (DG) rescued the hippocampus-dependent neurogenesis and memory deficits in APP/PS1 mice. Moreover, we demonstrated that the effect of ILK overexpression in the hippocampus was exerted via AKT-GSK3β pathway...

PURPOSE: Educators influence learning context through, among other things, triadic reciprocal causation-a behavioral model used in social cognitive theory. Eliciting responses from learners during instruction may contribute to learning by engaging their metacognition. In this study, metacognition was examined based on learners' experience with 2 different polling methods: student response systems (SRS), commonly known as "clickers," and a low-technology response system (LTRS), where students raise labeled signs, each with a different response...

Cognitive advantages for bilinguals have inconsistently been observed in different populations, with different operationalisations of bilingualism, cognitive performance, and the process by which language control transfers to cognitive control. This calls for studies investigating which aspects of multilingualism drive a cognitive advantage, in which populations and under which conditions. This study reports on two cognitive tasks coupled with an extensive background questionnaire on health, wellbeing, personality, language knowledge and language use, administered to 387 older adults in the northern Netherlands, a small but highly multilingual area...

OBJECTIVES: After a coma, one major challenge is the detection of awareness in patients with disorders of consciousness. In some patients, the only manifestation indicative of awareness is an appropriate emotional response. Preferred music is a powerful medium to elicit emotions and auto-biographical memory. Furthermore, music has been shown to improve cognitive functions both in healthy subjects and patients with neurological impairment. We hypothesized that signs of awareness could be enhanced in some patients with disorders of consciousness under appropriate emotional stimulation such as preferred music and also probably preferred odors...

Sleep enhances memory for emotional experiences, but its influence on the emotional response associated with memories is elusive. Here, we compared the influence of nocturnal sleep on memory for negative and neutral pictures and the associated emotional response in 8-11-year-old children, i.e., an age group with heightened levels of emotional memory-related sleep features. During all sessions, emotional responses as measured by subjective ratings, the late positive potential of the EEG (LPP) and heart rate deceleration (HRD) were recorded...

Transcranial direct current stimulation (tDCS) has been shown to enhance cognitive performance on a variety of tasks. It is hypothesized that tDCS enhances performance by affecting task related cortical excitability changes in networks underlying or connected to the site of stimulation facilitating long term potentiation. However, many recent studies have called into question the reliability and efficacy of tDCS to induce modulatory changes in brain activity. In this study, our goal is to investigate the individual differences in tDCS induced modulatory effects on brain activity related to the degree of enhancement in performance, providing insight into this lack of reliability...

The blood-brain barrier (BBB) is involved in the pathogenesis of Alzheimer's disease (AD). BBB is a highly selective semipermeable structural and chemical barrier which ensures a stable internal environment of the brain and prevents foreign objects invading the brain tissue. BBB dysfunction induces the failure of Aβ transport from brain to the peripheral circulation across the BBB. Especially, decreased levels of LRP-1 (low density lipoprotein receptor-related protein 1) and increased levels of RAGE (receptor for advanced glycation endproducts) at the BBB can cause the failure of Aβ transport...

Positive psychology has influenced multiple subfields within psychology and areas outside of psychology. While positive psychology's focus on positive mental health and character strengths did not appear to meaningfully impact neuropsychology in its earlier stages, more recent indications suggest that the neuropsychological literature, and perhaps the field as a whole, has begun to embrace related research and practice applications. In this context, positive neuropsychology has emerged as a neuropsychological orientation focused on the study and practice of promoting cognitive health...

OBJECTIVE: Our aim was to establish whether Exposure, a specialized tailored treatment for chronic low back pain, has any advantages over cognitive-behavioral therapy (CBT) among individuals with high fear-avoidance levels. Second, we planned to compare short and long versions of Exposure. Third, we aimed to investigate whether Exposure can be delivered in an outpatient psychological setting. METHOD: A total of 88 Caucasian participants (55% women) were randomized to three different psychological treatment conditions, Exposure-long, Exposure-short, and CBT...
