The presidency of gender in the Anglo-American taxonomy of sexualities has historically been haunted by the irruption of "other" parameters of medicalization, censure and caesura, not in the least absolute and relative measures of age. Where today's clinical psychologists feel the need to age-specify adult homosexuality in such Hirschfeldian terms as androphilia, however, the felt need is indeed still essentially clinical. That cosmopolitan expressions such as homosexual, LGB or queer rarely require such specifications relies on a protracted and today arguably complete disarticulation of sex/gender and age/maturity as parameters of sexual orientation, accreditation and mobilization...

Imitative stimuli presented from a first-person perspective (FPP) produce stronger visuomotor effects than those presented from a third-person perspective (TPP) due to the relatively greater response of the mirror neuron system (MNS) to FPP stimuli. Some previous studies utilizing TPP stimuli have reported no differences in MNS activity between moving and static bodies' stimuli. However, few studies have compared visuomotor effects of such stimuli when presented in the FPP. To clarify this issue, we measured cortical activation in 17 participants during a functional magnetic resonance imaging (MRI) imitation task involving three conditions: moving (a lifting finger was presented), static (an "X" appeared on a static finger), and control (an "X" appeared on a button)...

An adult female (22 years) of Christian orthodox religion was examined during the silent Lord's prayer, the most common, short prayer, with the aim of possible differentiation between belief and knowledge in her experience, analyzing the behavior of subgroups of theta and beta cerebral EEG rhythms, which occur through constant and occasional activation of cerebral regions. The participant was not trained in reading the prayer to herself or other people. EEG examination was performed by Nihon Kohden Corporation, EEG-1200-K Neurofax apparatus, in the monopolar longitudinal montage in the system of 10/20 electrodes aimed at determining the peak frequency value of each exploratory site...

High sensitivity and reactivity to behaviors of family members characterizes several forms of psychopathology, including self-inflicted injury (SII). We examined mother-daughter behavioral and psychophysiological reactivity during a conflict discussion using nonlinear dynamics to assess asymmetrical associations within time-series data. Depressed, SII, and control adolescents and their mothers participated (n=76 dyads). We expected that (1) mothers' evocative behaviors would affect behavioral and psychophysiological reactivity among depressed and, especially, SII adolescents, (2) adolescents' behaviors would not evoke mothers' behavioral or physiological reactivity, and (3) control teens and mothers would be less reactive, with no dynamic associations in either direction...

Insufficient sleep, as well as the incidence of anxiety disorders, both peak during adolescence. While both conditions present perturbations in fear-processing-related neurocircuitry, it is unknown whether these neurofunctional alterations directly link anxiety and compromised sleep in adolescents. Fourteen anxious adolescents (AAs) and 19 healthy adolescents (HAs) were compared on a measure of sleep amount and neural responses to negatively valenced faces during fMRI. Group differences in neural response to negative faces emerged in the dorsal anterior cingulate cortex (dACC) and the hippocampus...

The prefrontal cortex is believed to be responsible for execution of deceptive behavior and its involvement is associated with greater cognitive efforts. It is also generally assumed that deception is associated with the inhibition of default honest actions. However, the precise neurophysiological mechanisms underlying this process remain largely unknown. The present study was aimed to use functional magnetic resonance imaging to reveal the underlying functional integration within the prefrontal cortex during the task which requires that subjects to deliberately mislead an opponent through the sequential execution of deceptive and honest claims...

The first aim of this research was to assess the effectiveness, in terms of emotional and behavioral reactions, of moderately vs. highly TVWs (Threatening Visual Warnings) displayed on tobacco packs. Given the key role that emotional reactions play in explaining the effect of TVWs on behaviors, psychophysiological and self-report methods were used-for the first time in this context-to measure the emotions provoked by TVWs. The second aim of this research was to determine whether increasing the size of warnings, and their display on plain packaging (compared with branded packaging) would improve their effectiveness...

Addiction is increasingly discussed asa disorder of associative learning processes, with both operant and classical conditioning contributing to the development of maladaptive habits. Stress has long been known to promote drug taking and relapse and has further been shown to shift behavior from goal-directed actions towards more habitual ones. However, it remains to be investigated how acute stress may influence simple associative learning processes that occur before a habit can be established. In the present study, healthy young adults were exposed to either acute stress or a control condition half an hour before performing simple classical and operant conditioning tasks...

BACKGROUND: Previous research has shown relatively diminished medial prefrontal cortex activation and heightened psychophysiological responses during the recollection of personal events in post-traumatic stress disorder (PTSD), but the origin of these abnormalities is unknown. Twin studies provide the opportunity to determine whether such abnormalities reflect familial vulnerabilities, result from trauma exposure, or are acquired characteristics of PTSD. METHODS: In this case-control twin study, 26 male identical twin pairs (12 PTSD; 14 non-PTSD) discordant for PTSD and combat exposure recalled and imagined trauma-unrelated stressful and neutral life events using a standard script-driven imagery paradigm during functional magnetic resonance imaging and concurrent skin conductance measurement...

[Purpose] This research aimed to examine the effects of back massage and foot bath with blended essential oil on psychophysiological response in stroke patients. [Subjects and Methods] The subjects were 14 adult stroke patients randomly divided into the experimental group (7 patients) and the control group (7 patients). Physical and psychological stress, mood state and sleep satisfaction was measured using evaluation instruments and body temperature was measured with infrared thermography (T-1000). [Results] Measurements included physical and psychological stress, and mood state of the experiment group became significantly lower than that of the control group...

Nature therapy has been demonstrated to induce physiological relaxation. The psychophysiological effects of nature therapy (stimulation with bonsai trees) on adult male patients with spinal cord injury (SCI) were examined. Oxyhemoglobin concentration changes in the prefrontal cortex were measured using near-infrared spectroscopy, and heart rate variability was analyzed. Psychological responses were evaluated using the modified semantic differential method and Profile of Mood States (POMS) subscale scores. Visual stimulation of adult male patients with SCI elicited significantly decreased left prefrontal cortex activity, increased parasympathetic nervous activity, decreased sympathetic nervous activity, increased positive feelings, and resulted in lower negative POMS subscale scores...

This review serves as a systematic guide to the genetics of generalized anxiety disorder (GAD) and further focuses on anxiety-relevant endophenotypes, such as pathological worry fear of uncertainty, and neuroticism. We inspect clinical genetic evidence for the familialityl heritability of GAD and cross-disorder phenotypes based on family and twin studies. Recent advances of linkage studies, genome-wide association studies, and candidate gene studies (eg, 5-HTT, 5-HT1A, MAOA, BDNF) are outlined. Functional and structural neuroimaging and neurophysiological readouts relating to peripheral stress markers and psychophysiology are further integrated, building a multilevel disease framework...

The present study explores the notion of an out-group fear learning bias that is characterized by facilitated fear acquisition toward harm-doing out-group members. Participants were conditioned with two in-group and two out-group faces as conditioned stimuli. During acquisition, one in-group and one out-group face was paired with an aversive shock whereas the other in-group and out-group face was presented without shock. Psychophysiological measures of fear conditioning (skin conductance and pupil size) and explicit and implicit liking exhibited increased differential responding to out-group faces compared to in-group faces...

The ability to regulate our own physiological arousal when dealing with the emotional expression of our partner is crucial for satisfactory and stable intimate relationships. In previous physiological studies of marital interactions, researchers have found greater levels of psychophysiological arousal for members of the couple in conflictual interactions in comparison with positive interactions. Past researchers have established that intense and prolonged autonomic and neuroendocrine arousal during marital conflict can have negative consequences for mental and physical health...

At the time of school-age, the most frequent stress stimuli are related to school environment and educational process. Anxiety may play a big role in coping with stressful situations associated with school load. To approach this issue, we performed a real-life study at school during the classwork. The sample consisted of 36 healthy children aged 10 years, which were divided to low and high trait anxiety group based on the median value of the anxiety score. The investigations were carried out in the classroom during a stress condition (final exams) and non-stress condition (without any exam)...

REVIEW
Noémi Császár-Nagy, István Bókkon
In the 20th century, mother-infant separation shortly after birth in hospitals became routine and unique to humans. However, this hospital birth practice is different from the practice in our evolutionary history, where newborn survival depended on close and essentially continuous maternal contact. This time shortly after birth represents a psychophysiologically sensitive or critical period for programming future physiology and behaviour. We hypothesize that early maternal separation as conducted in conventional hospital practice may induce similar epigenetic changes similar to those found in various mental diseases that may also be implicated in neurodevelopmental disorders...

REVIEW
Jonas G Miller
Psychophysiological perspectives can provide unique insights into the nature and motivations of children's prosociality and inform our understanding of individual differences. Here, I review current research on prosociality involving some of the most common physiological measures in developmental psychology, including cortisol, various sympathetic nervous system measures, and high-frequency heart rate variability. The literature has been quite mixed, in part because the link between physiology and prosociality is context-dependent and person-dependent...

Several studies of self-monitoring dysfunction in schizophrenia have focused on the sense of agency to motor action using behavioral and psychophysiological techniques. So far, no study has ever tried to investigate whether the sense of agency or causal attribution for external events produced by self-generated decision-making is abnormal in schizophrenia. The purpose of this study was to investigate neural responses to feedback information produced by self-generated or other-generated decision-making in a multiplayer gambling task using even-related potentials and electroencephalogram synchronization...

OBJECTIVE: This study examined whether reward and punishment sensitivities, as conceptualised by Gray and McNaughton's revised Reinforcement Sensitivity Theory (RST), influenced young female drivers' attention towards a series of positive and negative anti-speeding advertisement images. Young females' increasing crash risk is associated with their engagement in risky behaviours which, in turn, has been associated with a stronger Behavioural Approach System (BAS; sensitive to rewards)...

Chiara Bartolucci, Giovanni Pietro Lombardo
This article examines research on hypnosis and suggestion, starting with the nineteenth-century model proposed by Enrico Morselli (1852-1929), an illustrious Italian psychiatrist and psychologist. The authors conducted an original psychophysiological analysis of hypnosis, distancing the work from the neuropathological concept of the time and proposing a model based on a naturalistic approach to investigating mental processes. The issues investigated by Morselli, including the definition of hypnosis and analysis of specific mental processes such as attention and memory, are reviewed in light of modern research...
