Hair testosterone and cortisol interactively predict problematic pornography use in a male sample
Approach-avoidance tendencies in problematic usage of the internet
Encoding of semantic structure shapes temporal order memory for visual object stimuli
Episodic memory does not perfectly reproduce past experiences but combines encoded episode-specific information and semantic knowledge in a constructive way. Previous research has shown that semantic category knowledge can bias location memory for individual items, suggesting that similar mechanisms may affect other key dimensions of episodic memory. Here, we investigated whether immediate temporal order memory is influenced by semantic relatedne…
Pavlovian-to-instrumental transfer effect after devaluation as indicator of habitual behavior together with stress responsivity predicts daily use of buying-shopping platforms
BACKGROUND AND AIMS: Stress responsivity and habitual behaviors are related to problematic online buying-shopping (BSh) according to the Interaction of Person-Affect-Cognition-Execution (I-PACE) model. This study aimed to investigate if symptoms of problematic online BSh, an experimental indicator of habitual behavior and the interaction of potentially habitual behavior and stress responsivity predict everyday use of buying-shopping platforms. PA…
Daily stress and gaming – an ambulatory assessment study in individuals with pathological, risky, and non-problematic gaming behavior
Effects of acute stress on cue reactivity and implicit cognitions in online compulsive buying-shopping disorder
Risky online buying-shopping behavior
Microstructural differences in the cingulum and the inferior longitudinal fasciculus are associated with (extinction) learning
Cognitive functions, such as learning and memory processes, depend on effective communication between brain regions which is facilitated by white matter tracts (WMT). We investigated the microstructural properties and the contribution of WMT to extinction learning and memory in a predictive learning task. Forty-two healthy participants completed an extinction learning paradigm without a fear component. We examined differences in microstructural p…
A single dose of hydrocortisone does not alter interhemispheric transfer of information or transcallosal integration
Stress has been suggested as a factor that may explain the link between altered functional lateralization and psychopathology. Modulation of the function of the corpus callosum via stress hormones may be crucial in this regard. Interestingly, there is evidence that interhemispheric integration and hemispheric asymmetries are modifiable by endocrinological influences. In previous studies, our group could show an enhancing effect of acute stress on…
How Shame and Guilt Influence Perspective Taking
Shame and guilt are negative social emotions that are sensitive to culture, and findings from past research have suggested that shame impairs perspective-taking cognitive ability more than guilt does. However, to the best of our knowledge, there is a lack of research that has considered culture and experimentally tested the effect of shame and guilt on perspective-taking. Taking an experimental perspective, this study aimed to examine how shame a…
Odours as context cues of emotional memories – The role of semantic relatedness
Odours constitute effective context cues, facilitating memory retrieval. Identifying factors which modulate the effectiveness of olfactory context cues can advance the understanding of processes underlying this effect. We hypothesized that the interplay of subjective stress and semantic relatedness between the odour and the learning material would modulate the effectiveness of an olfactory context cue. We further explored the effect of the odoran…
Treatment-Resistant Blunted HPA Activity, but Reversible Cardiovascular Stress Reactivity in Young Women With Eating Disorders
Previous research has provided evidence for a reduced neuroendocrine stress response in women with eating disorders (EDs). In the present study female in-patients with Anorexia and Bulimia nervosa were compared to female healthy controls (HC) before and after completing an in-patient treatment program. Salivary cortisol, alpha-amylase (sAA), heart rate response (HR), high-frequency heart rate variability (HF-HRV) and negative affective state were…
Implicit need for achievement predicts attenuated cortisol responses to difficult tasks
Writing about life goals
Rumination is a vulnerability factor for the onset and maintenance of emotional distress. This study examined whether writing about life goals is associated with a decrease in ruminative thinking and a reduced cortisol awakening response. 68 healthy participants either wrote about their personal life goals or a control topic. Writing about life goals was associated with a modest decrease in ruminative thinking and a reduced cortisol awakening res…
Stress-Induced Cortisol Level Elevations Are Associated With Reduced Negative Affect After Stress
OBJECTIVE: Stress is associated with increased negative affect and activation of the sympathetic nervous system and of the hypothalamic-pituitary-adrenal axis. However, the relationship between these stress systems and negative affect is incompletely understood. We therefore investigated positive and negative affects in relationship with salivary cortisol and salivary α-amylase (sAA) levels in a large sample of participants exposed to a psychosoc…
Media and Stress in Adolescent Boys in Germany
The study is on the effects of entertainment media on physiological and psychological indicators of stress. The concept of stress is considered to play a key role in the explanation of the effects of media use on aggression, academic performance, and health. Two types of media (television and video games) and violent versus nonviolent content were compared. Differential effects on physiological measures (heart rate [HR], heart rate variability [H…
Emotional modulation of the attentional blink
Individuals are often unable to identify the second target (T2) of two when it is presented within 500 ms after the first target (T1). This "attentional blink" (AB) is attenuated by an emotionally arousing T2. Stress is known to affect cognitive performance, in particular for emotional material. In the present study, we asked whether (a) an emotional T2 reduces the AB when preceded by an emotional T1 and (b) the emotional modulation of the AB is …
Dissociation of Cognitive and Emotional Empathy in Adults with Asperger Syndrome Using the Multifaceted Empathy Test (MET)
Introducing Masc
Hypothalamic Blood Flow Correlates Positively With Stress-Induced Cortisol Levels in Subjects With Social Anxiety Disorder
Objective: The adrenal excretion of cortisol in animals is dependent on the production of corticotropin-releasing factor in the paraventricular nucleus of the hypothalamus. The a priori hypothesis of this study was that hypothalamic regional cerebral blood flow (rCBF) would correlate positively with salivary cortisol levels in patients with social anxiety disorder (SAD) during anxiety provocation. Another objective was to evaluate whether salivar…
