Secure human attachment can promote support for climate change mitigation.

Attachment theory is an ethological approach to the development of durable, affective ties between humans. We propose that secure attachment is crucial for understanding climate change mitigation, because the latter is inherently a communal phenomenon resulting from joint action and requiring collective behavioral change. Here, we show that priming attachment security increases acceptance (Study 1: n = 173) and perceived responsibility toward anthropogenic climate change (Study 2: n = 209) via increased empathy for others. Next, we demonstrate that priming attachment security, compared to a standard National Geographic video about climate change, increases monetary donations to a proenvironmental group in politically moderate and conservative individuals (Study 3: n = 196). Finally, through a preregistered field study conducted in the United Arab Emirates (Study 4: n = 143,558 food transactions), we show that, compared to a message related to carbon emissions, an attachment security-based message is associated with a reduction in food waste. Taken together, our work suggests that an avenue to promote climate change mitigation could be grounded in core ethological mechanisms associated with secure attachment.

The cognitive science of COVID-19: Acceptance, denial, and belief change.

Because the spread of pandemics depends heavily on human choices and behaviors, dealing with COVID-19 requires insights from cognitive science which integrates psychology, neuroscience, computer modeling, philosophy, anthropology, and linguistics. Cognitive models can explain why scientists adopt hypotheses about the causes and treatments of disease based on explanatory coherence. Irrational deviations from good reasoning are explained by motivated inference in which conclusions are influenced by personal goals that contribute to emotional coherence. Decisions about COVID-19 can also be distorted by well-known psychological and neural mechanisms. Cognitive science provides advice about how to improve human behavior in pandemics by changing beliefs and by improving behaviors that result from intention-action gaps.

The nucleus accumbens and alcoholism: a target for deep brain stimulation.

Alcohol use disorder (AUD) is a difficult to treat condition with a significant global public health and cost burden. The nucleus accumbens (NAc) has been implicated in AUD and identified as an ideal target for deep brain stimulation (DBS). There are promising preclinical animal studies of DBS for alcohol consumption as well as some initial human clinical studies that have shown some promise at reducing alcohol-related cravings and, in some instances, achieving long-term abstinence. In this review, the authors discuss the evidence and concepts supporting the role of the NAc in AUD, summarize the findings from published NAc DBS studies in animal models and humans, and consider the challenges and propose future directions for neuromodulation of the NAc for the treatment of AUD.

Sex differences in drug addiction and response to exercise intervention: From human to animal studies.

Accumulated research supports the idea that exercise could be an option of potential prevention and treatment for drug addiction. During the past few years, there has been increased interest in investigating of sex differences in exercise and drug addiction. This demonstrates that sex-specific exercise intervention strategies may be important for preventing and treating drug addiction in men and women. However, little is known about how and why sex differences are found when doing exercise-induced interventions for drug addiction. In this review, we included both animal and human that pulled subjects from a varied age demographic, as well as neurobiological mechanisms that may highlight the sex-related differences in these potential to assess the impact of sex-specific roles in drug addiction and exercise therapies.

Religion, spirituality, and physical health in cancer patients: A meta-analysis.

Although religion/spirituality (R/S) is important in its own right for many cancer patients, a large body of research has examined whether R/S is also associated with better physical health outcomes. This literature has been characterized by heterogeneity in sample composition, measures of R/S, and measures of physical health. In an effort to synthesize previous findings, a meta-analysis of the relation between R/S and patient-reported physical health in cancer patients was performed. A search of PubMed, PsycINFO, the Cumulative Index to Nursing and Allied Health Literature, and the Cochrane Library yielded 2073 abstracts, which were independently evaluated by pairs of raters. The meta-analysis was conducted for 497 effect sizes from 101 unique samples encompassing more than 32,000 adult cancer patients. R/S measures were categorized into affective, behavioral, cognitive, and 'other' dimensions. Physical health measures were categorized into physical well-being, functional well-being, and physical symptoms. Average estimated correlations (Fisher z scores) were calculated with generalized estimating equations with robust variance estimation. Overall R/S was associated with overall physical health (z = 0.153, P < .001); this relation was not moderated by sociodemographic or clinical variables. Affective R/S was associated with physical well-being (z = 0.167, P < .001), functional well-being (z = 0.343, P < .001), and physical symptoms (z = 0.282, P < .001). Cognitive R/S was associated with physical well-being (z = 0.079, P < .05) and functional well-being (z = 0.090, P < .01). 'Other' R/S was associated with functional well-being (z = 0.100, P < .05). In conclusion, the results of the current meta-analysis suggest that greater R/S is associated with better patient-reported physical health. These results underscore the importance of attending to patients' religious and spiritual needs as part of comprehensive cancer care.

Street crossing behavior in younger and older pedestrians: an eye- and head-tracking study.

BACKGROUND: Crossing a street can be a very difficult task for older pedestrians. With increased age and potential cognitive decline, older people take the decision to cross a street primarily based on vehicles' distance, and not on their speed. Furthermore, older pedestrians tend to overestimate their own walking speed, and could not adapt it according to the traffic conditions. Pedestrians' behavior is often tested using virtual reality. Virtual reality presents the advantage of being safe, cost-effective, and allows using standardized test conditions. METHODS: This paper describes an observational study with older and younger adults. Street crossing behavior was investigated in 18 healthy, younger and 18 older subjects by using a virtual reality setting. The aim of the study was to measure behavioral data (such as eye and head movements) and to assess how the two age groups differ in terms of number of safe street crossings, virtual crashes, and missed street crossing opportunities. Street crossing behavior, eye and head movements, in older and younger subjects, were compared with non-parametric tests. RESULTS: The results showed that younger pedestrians behaved in a more secure manner while crossing a street, as compared to older people. The eye and head movements analysis revealed that older people looked more at the ground and less at the other side of the street to cross. CONCLUSIONS: The less secure behavior in street crossing found in older pedestrians could be explained by their reduced cognitive and visual abilities, which, in turn, resulted in difficulties in the decision-making process, especially under time pressure. Decisions to cross a street are based on the distance of the oncoming cars, rather than their speed, for both groups. Older pedestrians look more at their feet, probably because of their need of more time to plan precise stepping movement and, in turn, pay less attention to the traffic. This might help to set up guidelines for improving senior pedestrians' safety, in terms of speed limits, road design, and mixed physical-cognitive trainings.

Does Amount and Type of Activity Matter in Behavioral Activation? A Preliminary Investigation of the Relationship between Pleasant, Functional, and Social Activities and Outcome.

BACKGROUND: Accumulating evidence supports behavioral activation (BA) as an effective stand-alone treatment for improving depression and related conditions, though little is known about the factors that influence positive outcomes. Such research is ripe for future dissemination and implementation efforts, particularly among vulnerable older adult populations in need of such efficacious and transportable treatments. AIMS: Given the central but largely unexamined role that increasing activities plays in BA, we investigated the association between participation in weekly activities and treatment outcome. METHOD: As a preliminary study of this research question, we report on a sample of 20 older adults with symptoms of depression and complicated bereavement who completed 5 weeks of BA, pre- and posttreatment measures, and weekly planners of BA activities. All activities were coded as either functional or pleasurable (by participants) and if they were social in nature (by trained coders). RESULTS: Overall, BA was associated with reductions in symptomatology. However, participants' total number of reported activities, and their relative proportion of functional, pleasurable, and social activities, did not significantly relate to their improvement in symptoms. CONCLUSION: One interpretation of the findings suggests that countering avoidance more generally, potentially independent of the specific type or total amount of activation activities, may be associated with amelioration of symptomatology.

Why behavior change is difficult to sustain.

Unhealthy behavior is responsible for much human disease, and a common goal of contemporary preventive medicine is therefore to encourage behavior change. However, while behavior change often seems easy in the short run, it can be difficult to sustain. This article provides a selective review of research from the basic learning and behavior laboratory that provides some insight into why. The research suggests that methods used to create behavior change (including extinction, counterconditioning, punishment, reinforcement of alternative behavior, and abstinence reinforcement) tend to inhibit, rather than erase, the original behavior. Importantly, the inhibition, and thus behavior change more generally, is often specific to the "context" in which it is learned. In support of this view, the article discusses a number of lapse and relapse phenomena that occur after behavior has been changed (renewal, spontaneous recovery, reinstatement, rapid reacquisition, and resurgence). The findings suggest that changing a behavior can be an inherently unstable and unsteady process; frequent lapses should be expected. In the long run, behavior-change therapies might benefit from paying attention to the context in which behavior change occurs.

Observational study on the efficacy of the supplementation with a preparation with several minerals and vitamins in improving mood and behaviour of healthy puerperal women.

We investigated whether a formulation containing vitamins and minerals (vit&min) could improve the worsening of mood changes occurring after delivery ("a.d."). The study was performed in 552 healthy non-anaemic puerperal women ("p.w") without risk factors for puerperal depression ("p.d"). They were at their first full-term pregnancy, and spontaneously delivered healthy newborns. The Edinburgh Depression Postnatal scale (EPDS) evaluates the psychological status of "p.w". EPDS was administered the 3rd (visit 1), 15th (visit 2) and 30th (visit 3) day "a.d.". An EPDS >12 indicates a major susceptibility to "p.d". At the same time intervals, haemoglobin, iron and ferritin (haematological parameters) levels were evaluated. After visit 1, the subjects were randomized to vit&min treatment (group A; N.274) or to calcium/vitamin D3 treatment (group B; N.278). In both groups haematological parameters significantly increased without differences between the groups. EPDS score improved in both groups, but in the group A, the EPDS decrease was significantly larger (p < 0.05) in comparison to the group B. This effect is mainly evident in subjects with a basal EPDS ≥ 12. An early examination of psychological condition could select "p.w." with a high susceptibility to neuronal changes occurring postpartum. Vit&min favourably modulates brain functions antagonizing the evolution to "p.d".

The adaptive neuroplasticity hypothesis of behavioral maintenance.

Physical activity is a seemingly simple and clinically potent method to decrease morbidity and mortality in people with coronary heart disease (CHD). Nonetheless, long-term maintenance of physical activity remains a frustratingly elusive goal for patients and practitioners alike. In this paper, we posit that among older adults with CHD, recidivism after the initiation of physical activity reflects maladaptive neuroplasticity of malleable neural networks, and people will revert back to learned and habitual physical inactivity patterns, particularly in the setting of stress or depression. We hypothesize that behavioral interventions that successfully promote physical activity may also enhance adaptive neuroplasticity and play a key role in the maintenance of physical activity through the development of new neuronal pathways that enhance functional ability in older adults. Conversely, without such adaptive neuroplastic changes, ingrained maladaptive neuroplasticity will prevail and long-term maintenance of physical activity will fail. In this paper we will: (1) describe the enormous potential for neuroplasticity in older adults; (2) review stress and depression as examples of maladaptive neuroplasticity; (3) describe an example of adaptive neuroplasticity achieved with a behavioral intervention that induced positive affect in people with CHD; and (4) discuss implications for future work in bench to bedside translational research.

Brain-behavior relationship in a case of successful ECT for drug refractory catatonic OCD.

This case report describes the successful response to electroconvulsive therapy (ECT) in a patient with an unusual presentation of catatonia, whose onset occurred in the context of an extremely severe form of refractory obsessive-compulsive disorder (OCD). We correlated the clinical improvement in catatonic and OCD symptoms with specific changes in brain function as shown by regional cerebral blood flow scans, neurological soft signs examination, and neuropsychological testing. All assessments were conducted before and after the ECT course. The results strongly suggest that a right hemisphere dysfunction was the neural correlate of our patient's symptoms, and that ECT, by reverting this abnormality, may serve as an effective therapeutic approach for refractory catatonic OCD.

[Return to work after brain lesions: cognitive and behavioral factors]. / Troubles cognitifs et comporte mentaux après lésion cérébrale: impact sur la reprise professionnelle.

Complete or partial return to work (RTW) succeeds in around 40% of TBI and 25% of stroke patients. Positive factors include: (1) post-traumatic amnesia, hospitalization length, age, race, pretraumatic work and socio-educational status, quality of life, (2) premorbid intellectual level, learning, language and attentional, (3) social cognition and deficit's awareness and (4) absence of behavioural impairment. In stroke, RTW is associated with normal neurological and cognitive/communication abilities. Vocational rehabilitation necessitates: (1) cognitive retraining (speed, visuospatial skills and memory), (2) behavioural approach (compensation, organization, abstraction) and (3) adaptation of work profile. Case management models, with early intervention, continuity of care and coordination, increase twofold partial or complete adapted RTW.

Lifestyle and the aging brain: interactive effects of modifiable lifestyle behaviors and cognitive ability in men from midlife to old age.

We examined the influence of lifestyle on brain aging after nearly 30 years, and tested the hypothesis that young adult general cognitive ability (GCA) would moderate these effects. In the community-dwelling Vietnam Era Twin Study of Aging (VETSA), 431 largely non-Hispanic white men completed a test of GCA at mean age 20. We created a modifiable lifestyle behavior composite from data collected at mean age 40. During VETSA, MRI-based measures at mean age 68 included predicted brain age difference (PBAD), Alzheimer's disease (AD) brain signature, and abnormal white matter scores. There were significant main effects of young adult GCA and lifestyle on PBAD and the AD signature (ps ≤ 0.012), and a GCA-by-lifestyle interaction on both (ps ≤ 0.006). Regardless of GCA level, having more favorable lifestyle behaviors predicted less advanced brain age and less AD-like brain aging. Unfavorable lifestyles predicted advanced brain aging in those with lower age 20 GCA, but did not affect brain aging in those with higher age 20 GCA. Targeting early lifestyle modification may promote dementia risk reduction, especially among lower reserve individuals.

Playing with fire. Understanding how experiencing a fire in an immersive virtual environment affects prevention behavior.

A potentially effective way to influence people's fire prevention behavior is letting them experience a fire in an immersive virtual environment (IVE). We analyze the effects of experiencing a fire in an IVE (versus an information sheet) on psychological determinants of behavior-knowledge, vulnerability, severity, self-efficacy, and locus of control-based mainly on arguments from Protection Motivation Theory and the Health Belief Model. Crucial in our setup is that we also relate these determinants to actual prevention behavior. Results show that IVE has the hypothesized effects on vulnerability, severity, and self-efficacy, and an unexpected negative effect on knowledge. Only knowledge and vulnerability showed subsequent indirect effects on actual prevention behavior. There remains a direct positive effect of IVE on prevention behavior that cannot be explained by any of the determinants. Our results contradict the implicit assumption that an induced change in these psychological determinants by IVE, necessarily implies a change in behavior. A recommendation for research on the effects of IVE's is, whenever possible, to study the actual target behavior as well.

Neurocognitive and behavioral functioning in frontal lobe epilepsy: a review.

Frontal lobe epilepsy (FLE) is a seizure disorder with a lower prevalence than temporal lobe epilepsy (TLE). Despite its consequences on cognitive and emotional well-being, the neuropsychology of FLE has not been well studied. By contrast, TLE has been studied meticulously, leading to a relevant understanding of memory and the functional characteristics of the temporal and limbic circuits. The neuropsychological studies on FLE report deficits in motor coordination and planning, reduced attention span, and difficulties in response inhibition in complex cognitive tasks. This review aims to illustrate the most relevant neurocognitive dimensions, psychiatric comorbidity, and postoperative neuropsychological outcome of FLE. Methodological suggestions for future research are also included by critically reviewing the existing literature.

Concepts and mechanisms of generalized central nervous system arousal.

A concept of generalized arousal of the CNS is presented and given an operational definition that leads to quantitative physical measures. Because this primitive arousal function underlies all motivated behavioral responses, cognitive functions, and emotional expression, disorders of generalized arousal can be associated with a large number of problems in medicine and public health, including vegetative states, attentional disorders, depression, occupational hazards, and problems with sleep and anesthesia. Some of its known mechanisms are briefly reviewed, at the levels of neuroanatomy, neurophysiology, and functional genomics. Generalized arousal contributes to the excitement and the activation of behaviors during specific arousal states. Data are summarized for four genomic/neurochemical systems through which changes in generalized arousal could affect sexual arousal, two of which heighten, and the other two of which reduce arousal.

A randomized controlled trial of an early intervention program in low birth weight children: outcome at 2 years.

BACKGROUND: Preterm infants are at increased risk of cognitive, motor and behavioral problems. Different intervention programs have been designed in an attempt to improve outcome, but the results are conflicting. OBJECTIVE: To examine the effects of an early intervention program on cognitive, motor and behavioral problems and parenting stress among low birth weight children at 2 years corrected age. METHODS: A randomized controlled trial was conducted including infants with a birth weight <2000 g treated at the University Hospital of North Norway, to examine the effects of a modified version of the Mother-Infant Transaction Program on cognitive, motor and behavioral outcomes and parenting stress. The children were assessed with the Bayley Scales of Infant Development and the Child Behavior Checklist/2-3 (CBCL) and the Parenting Stress Index were administered to the parents at 2 years corrected age. RESULTS: Sixty-nine children in the intervention group and 67 in the control group were assessed at 2 years. There were no differences between the groups in cognitive or motor outcomes. The intervention group scored consistently lower on all CBCL syndrome scales, but no difference was significant. The mothers in the intervention group reported significantly lower parental stress in both child and parent domain, whereas the fathers reported lower stress in child domain compared to the control group. CONCLUSION: This early intervention program does not improve cognitive, motor or behavioral outcomes at 2 years. There was a significant reduction in parenting stress reported by both mothers and fathers in the intervention group.

Temperature-dependent behaviors of parasitic helminths.

Parasitic helminth infections are the most common source of neglected tropical disease among impoverished global communities. Many helminths infect their hosts via an active, sensory-driven process in which environmentally motile infective larvae position themselves near potential hosts. For these helminths, host seeking and host invasion can be divided into several discrete behaviors that are regulated by both host-emitted and environmental sensory cues, including heat. Thermosensation is a critical sensory modality for helminths that infect warm-blooded hosts, driving multiple behaviors necessary for host seeking and host invasion. Furthermore, thermosensory cues influence the host-seeking behaviors of both helminths that parasitize endothermic hosts and helminths that parasitize insect hosts. Here, we discuss the role of thermosensation in guiding the host-seeking and host-infection behaviors of a diverse group of helminths, including mammalian-parasitic nematodes, entomopathogenic nematodes, and schistosomes. We also discuss the neural circuitry and molecular pathways that underlie thermosensory responses in these species.

REVIEW OBJECTIVE/QUESTION: The objective of this umbrella review is to examine the effectiveness of different types of weight management, smoking cessation and alcohol reduction interventions in producing explicitly measured behavior change or proxy measures of behavior change in pregnant women.Specifically the review question is: are weight management, smoking cessation and alcohol reduction interventions effective in producing behavior change in pregnant women?

Correlates of physical activity in adolescents of public schools in curitiba, paraná, brazil / Correlatos da atividade física em adolescentes de escolas públicas de curitiba, paraná

ABSTRACT Objective: To verify the association of nutritional status, biological maturation, social support and self-efficacy with the physical activity level of 2,347 students of both sexes, aged between 11 and 15 years old, enrolled in state schools in the city of Curitiba, Paraná, Brazil. Methods: Anthropometric measurements of body mass, height and sitting height were collected. The assessment of biological maturation was based on the analysis of the age at peak height and sexual maturity. The physical activity level, social support from parents and friends and self-efficacy were evaluated by self-reported questionnaires. Sex/age-specific body mass index (BMI) cutoff points identified the nutritional status. Gross and adjusted binary logistic regression were used to obtain odds (OR) ratios with 95% confidence intervals (95%CI), adopting p≤0.05 as significant. Results: More than half (52.3%; n=1,227) of students were active, with boys in a higher proportion (64.1%; p≤0.01). The correlates of physical activity were: nutritional status (OR 1.25; 95%CI 1.01-1.56), early somatic maturation (OR 0.71; 95%CI 0.54-0.93), moderate (OR 1.85; 95%CI 1.50-2.30) and high social support from parents (OR 2.70; 95%CI 2.11-3.42) and high social support from friends (OR 1.78; 95%CI 1.42-2.24). Conclusions: Nutritional status, early somatic maturation, social support of parents and friends were correlates of physical activity. Overweight girls with moderate and high parental support and boys with greater social support from parents and friends were more active. Girls with early somatic maturation were less active.

RESUMO Objetivo: Verificar a associação do estado nutricional, da maturação biológica, do apoio social e da autoeficácia com o nível de atividade física de 2.347 escolares, de ambos os sexos, com idades entre 11 e 15 anos, de escolas estaduais da cidade de Curitiba, Paraná. Métodos: Foram coletadas as medidas antropométricas de massa corporal, estatura e altura sentada. A avaliação da maturação biológica foi realizada pelas análises da idade do pico de velocidade de altura e maturação sexual. O nível de atividade física, o apoio social dos pais e dos amigos e a autoeficácia foram analisados por questionários autorreportados. O estado nutricional foi obtido por meio de pontos de corte de índice de massa corpórea (IMC) específicos para idade e sexo. Razões de chances com intervalos de confiança de 95% (IC95%) foram obtidas por meio da regressão logística binária bruta e ajustada, adotando-se p<0,05. Resultados: Pouco mais da metade (52,3%; n=1.227) dos escolares é ativa, sendo os meninos em maior proporção (64,1%; p≤0,01). Foram associados com atividade física: estado nutricional (Odds Ratio [OR] 1,25; IC95% 1,01-1,56), maturação somática precoce (OR 0,71; IC95% 0,54-0,93), moderado e elevado apoio social dos pais (OR 1,85; IC95% 1,50-2,30 e OR 2,70; IC95% 2,11-3,42, respectivamente) e elevado apoio social dos amigos (OR 1,78; IC95% 1,42-2,24). Conclusões: O estado nutricional, a maturação somática precoce, o apoio social dos pais e dos amigos foram correlatos da atividade física. Meninas com excesso de peso e com moderado e elevado apoio social dos pais, e meninos com maior apoio social dos pais e dos amigos foram mais ativos, enquanto meninas maturadas precocemente, menos ativas.
