A number of papers have challenged research on physiological and psychological influences on perception by claiming to show that such findings can be explained by nonperceptual factors such as demand characteristics. Relatedly, calls for separating perception from judgment have been issued. However, such efforts fail to consider key processes known to shape judgment processes: people's inability to report accurately on their judgments, conversational dynamics of experimental research contexts, and misattribution and discounting processes...

Natural physique competitions are based on subjective judgments of how a competitor appears on show day. Prior to competition, there is a prolonged dieting phase referred to as contest preparation. The primary goal is to reduce body fat levels while maintaining skeletal muscle mass. The study tracked the physiological and psychological changes for a 24 year old female preparing for a physique competition. PURPOSE: The study was conducted to describe the physiological and psychological changes of a female physique competitor who engages in long-term contest preparation...

Chronic stress conditions can lead to considerable and extensible changes in physiological and psychological performances, and in emergence of risk for various somatic diseases. On the other hand, the neuropeptide oxytocin is reported to increase the resistance of the organism to stress and modulate activity of autonomic nervous system. Chronic corticosterone administration is used as a rat model for a state observed in terms of chronic stress exposure, when negative feedback mechanism of hypothalamus-pituitary-adrenal axis activity is disrupted...

BACKGROUND: Psychological stress increases the circulating levels of the stress hormones cortisol and norepinephrine (NE). Chronic exposure to elevated stress hormones has been linked to a reduced response to chemotherapy through induction of DNA damage. We hypothesize that stress hormone signalling may induce DNA damage through the production of reactive oxygen species (ROS)/reactive nitrogen species (RNS) and interference in DNA repair processes, promoting tumourigenesis. METHODS: Breast cancer cell lines were incubated with physiological levels of cortisol and NE in the presence and absence of receptor antagonists and inducible nitric oxide synthase (iNOS) inhibitors and DNA damage measured using phosphorylated γ-H2AX...

Carpal tunnel syndrome is the most common entrapment neuropathy, affecting the median nerve at the wrist. Acupuncture is a minimally-invasive and conservative therapeutic option, and while rooted in a complex practice ritual, acupuncture overlaps significantly with many conventional peripherally-focused neuromodulatory therapies. However, the neurophysiological mechanisms by which acupuncture impacts accepted subjective/psychological and objective/physiological outcomes are not well understood. Eligible patients (n = 80, 65 female, age: 49...

BACKGROUND: Pediatric obesity is the most prevalent nutritional disorder in American children. The detrimental social, psychological, and physiological effects of obesity call for pediatricians to address this health concern. The literature demonstrates that clinicians are underreporting the diagnosis of obesity in the pediatric setting. The primary purpose of this study was to determine if pediatricians at one pediatrics clinic in the Ochsner Health System are documenting the presence of an overweight or obese body mass index (BMI) as a diagnosis in the medical record...

OBJECTIVES: The pathways by which physical activity impacts on participants' health are still not fully understood. The purpose of the present study was to go beyond existing research by combining methods from survey-based and experimental stress research, and by examining whether the potential of vigorous physical activity (VPA) to attenuate physiological and psychological stress responses is moderated by participants' subjective stress perception. METHODS: The sample consisted of 42 undergraduate students (M=21...

The prevalence rates of post-traumatic stress disorder (PTSD) have been estimated to be several times higher in military populations compared to the national average. Special Tactics operators are a group that is more likely to avoid seeking psychological care due to the stigma and other consequences the diagnosis may have on their military careers. There is a need for more effective and less stigmatizing interventions to treat this population. Psychophysiological methods have been proven to be efficacious in treating PTSD, yet have received less attention as an adjunctive intervention...

The color red has been shown to alter emotions, physiology, psychology, and behavior. Research has suggested that these alterations could possibly be due to a link between red and perceived dominance. In this study we examined if the color red is implicitly associated to the concept of dominance. In addition, we similarly hypothesized that blue is implicitly linked to rest. A modified Stroop word evaluation task was used in which 30 participants (23.07 ± 4.42 years) were asked to classify words shown in either red, blue, or gray (control condition), as being either dominant- or rest-related...

Several studies have explored the predictability of placebo and nocebo individual responses by investigating personality factors and expectations of pain decreases and increases. Psychological factors such as optimism, suggestibility, empathy and neuroticism have been linked to placebo effects, while pessimism, anxiety and catastrophizing have been associated to nocebo effects. We aimed to investigate the interplay between psychological factors, expectations of low and high pain and placebo hypoalgesia and nocebo hyperalgesia...

Children who have suffered early abuse or neglect may later present with significant health and behavior problems that may persist long after the abusive or neglectful environment has been remediated. Neurobiological research suggests that early maltreatment may result in an altered psychological and physiologic response to stressful stimuli, a response that deleteriously affects the child's subsequent development. Pediatricians can assist caregivers by helping them recognize the abused or neglected child's emotional and behavioral responses associated with child maltreatment and guide them in the use of positive parenting strategies, referring the children and families to evidence-based therapeutic treatment and mobilizing available community resources...

Patients with extensive burn injuries suffer from multisystem trauma, which affects their medical, psychological, and social well-being for many years. Monitoring those patients has revealed changes in the endocrine, cardiac, and respiratory systems years after the injury. Our study tries to examine whether changes manifest as a higher risk of death during their lifespan, compared with the general population. Data from the years 1998 to 2013 regarding two groups of patients was obtained from a national trauma registry: one group had suffered burns over 20% of their TBSA and survived the hospitalization period and the second group was a control group of patients admitted with minimal trauma (Injury Severity Score = 1-minor injury to a single body region)...

Since time immemorial humans have utilized natural products and therapies for their healing properties. Even now, in the age of genomics and on the cusp of regenerative medicine, the use of complementary and alternative medicine (CAM) approaches represents a popular branch of health care. Furthermore, there is a trend towards a unified medical philosophy referred to as Integrative Medicine (IM) that represents the convergence of CAM and conventional medicine. The IM model not only considers the holistic perspective of the physiological components of the individual, but also includes psychological and mind-body aspects...

We investigated whether sadness elicited by two different situations-loss of someone (loss) and failure to achieve a goal (failure)-had different physiological responses. Seventy-four participants were randomly assigned to one of three conditions (loss, failure, and neutral). Physiological responses were recorded during an imagery task that was designed to evoke sadness. The results of characteristics in the subjective ratings indicated that loss-evoked sadness was only associated with expressive words relating to tears...

Scar is the natural end of wound healing, but pathologic scar will form with the excessive hyperplasia. The problems which thus come not only include the physiological and psychological disorders caused by the change of appearance or dysfunction, but also include the economic burden for both families of the patients and society induced by the requirement of plastic or functional reconstruction. The formation of pathologic scars is affected by many factors involved in the process of wound healing, such as excessive inflammation, abnormal tissue repair, and lingering repair termination, which involve a lot of signaling pathways...

The ability to quickly and accurately determine cortisol as a biomarker for stress is a valuable tool in assessing the wellbeing of NHP. In this study, 2 methods of collecting saliva (a commercial collection device and passive drool) and the resulting free salivary cortisol levels were compared with total serum cortisol concentration in rhesus macaques (Macaca mulatta), cynomolgus macaques (Macaca fascicularis) and African green monkeys (Chlorocebus aethiops) at 2 collection time points. Serum and salivary cortisol levels were determined using a competitive quantitative ELISA...

BACKGROUND: Several studies about humans and animals have separately examined the effects of prenatal nutrition and stress on fetal development, pregnancy, and birth outcomes, and subsequent child health and disease risk. Although substantial evidence from non-pregnant literature supports the presence of bidirectional interactions between nutrition and stress at various psychological, behavioral, and physiological levels, such interaction effects have not yet been systematically examined in the context of pregnancy...

This review highlights recent advances in research addressing intimate partner relationships and health. Consideration of the strong mutual influences that the members of a couple have on each other's mental and physical health trajectories provides a new way to view the health implications of couples' convergence or interdependence; marital closeness can have a clear downside when one partner has mental or physical health problems. Couples' interconnectedness can also be leveraged to promote better treatment outcomes...
