Sensation seeking

Yaling Yang, Shantanu H Joshi, Neda Jahanshad, Paul M Thompson, Laura A Baker
Verbal and physical aggression begin early in life and steadily decline thereafter in normal development. As a result, elevated aggressive behavior in adolescence may signal atypical development and greater vulnerability for negative mental and health outcomes. Converging evidence suggests that brain disturbances in regions involved in impulse control, emotional regulation, and sensation seeking may contribute to heightened aggression. However, little is known regarding the neural mechanisms underlying subtypes of aggression (i...

OBJECTIVES: The arousal regulation model of affective disorders attributes an important role in the pathophysiology of affective disorders to dysregulation of brain arousal regulation. According to this model, sensation avoidance and withdrawal in depression and sensation seeking and hyperactivity in mania can be explained as auto-regulatory attempts to counteract a tonically high (depression) or unstable (mania) arousal. The aim of this study was to compare brain arousal regulation between manic and depressive bipolar patients and healthy controls...

In recent decades, research has identified a set of impulsive/disinhibited personality variables closely associated with drug addiction. As well as this, disorders linked with these variables, such as ADHD and personality disorders, are being closely studied in the field of drug addiction. Although much knowledge has been accumulated about the relation of these variables and disorders taken separately, less is known about how these constructs allow identify-specific profiles within the drug dependent population to be identified...

Cannabis is the illicit substance most widely used by adolescents. Certain personality traits such as impulsivity and sensation seeking, and the subjective effects experienced after substance use (e.g. euphoria or relaxation) have been identified as some of the main etiological factors of consumption. This study aims to categorize a sample of adolescent cannabis users based on their most dominant personality traits (internalizing and externalizing profile). Then, to make a comparison of both profiles considering a set of variables related to consumption, clinical severity and subjective effects experienced...

Adolescence is a period marked by increases in risk taking, sensation seeking, and emotion dysregulation. Neurobiological models of adolescent development propose that lagging development in brain regions associated with affect and behavior control compared to regions associated with reward and emotion processing may underlie these behavioral manifestations. Cross-sectional studies have identified several functional brain networks that may contribute to risk for substance use and psychopathology in adolescents...

Participation in extreme rituals (e.g., fire-walking, body-piercing) has been documented throughout history. Motivations for such physically intense activities include religious devotion, sensation-seeking and social bonding. The present study aims to explore an extreme ritual within the context of bondage/discipline, dominance/submission and sadism/masochism (BDSM): the 'Dance of Souls', a 160-person ritual involving temporary piercings with weights or hooks attached and dancing to music provided by drummers...

In adolescence, such matters as substance use and impulsiveness may give rise to problematic behavior repertoires. This study was therefore done to analyze the predictive value of sensation-seeking and impulsiveness dimensions related to the functions of aggression (reactive/proactive) and types of expression (physical/relational). A total of 822 high school students in Almeria (Spain) aged 13-18, were administered the Sensation-Seeking Scale, the State Impulsiveness Scale and Peer Conflict Scale. The results show the existence of a positive correlation of the majority of factors analyzed, both in impulsiveness and sensation-seeking, with respect to the different types of aggression...

There is little known about factors that contribute to the comorbidity of cigarette smoking and obesity. The current study sought to test whether exercise self-efficacy moderated the relation between anxiety sensitivity (fear of internal sensations) and BMI and exercise tolerance among cigarette smokers. Smokers (n = 72; 50% female; Mcpd = 19.3, SD = 10.65) were recruited to participate in a smoking cessation treatment trial. During medical screen, we measured weight, height, and exercise tolerance (functional capacity) employing a standardized maximal exercise testing protocol...

Humans exhibit sex differences in competitiveness, sensation seeking and risk-taking attitude, which are required in sports. These attributes are often linked to prenatal testosterone (PT) exposure. The second-to-fourth digit length ratio (2D:4D) is an indicator of PT exposure. A lower 2D:4D indicates higher PT exposure and vice versa. Males generally have a lower 2D:4D than females. Sensation- and/or thrill-seeking behaviours have also been found to be negatively associated with 2D:4D. Boxing and judo are considered to be high-risk sports...

BACKGROUND: Problem substance use often begins in adolescence. This vulnerability likely stems, at least partially, from relatively rapid increases in sensation seeking occurring in early to mid-adolescence and more gradual improvements in impulse control occurring through later adolescence. Better understanding how these processes develop in high-risk youth may lead to enhanced substance use disorder treatment and prevention strategies. METHODS: We characterized trajectories of self-reported impulsivity and sensation seeking in 305 FH+ youths who at minimum had a father with a history of alcohol or other drug use disorders and 81 youths with no family histories of substance use disorders (FH-)...

BACKGROUND: Attention-deficit hyperactivity disorder (ADHD) shows clear, albeit heterogeneous, cognitive dysfunctions. However, personality traits are not well understood in adults with ADHD, and it is unclear whether they are predisposing factors or phenotypical facets of the condition. AIMS: To assess whether personality traits of impulsivity, sensation seeking and sensitivity to punishment and reward are predisposing factors for ADHD or aspects of the clinical phenotype...

Wedgies-the upward yanking of another's underpants from the rear to wedge them between the buttocks-can be administered playfully, maliciously, or adventurously; at forces ranging from gentle to "atomic"; and with or without the foreknowledge or consent of the recipient. Wedgies have been documented anecdotally in the popular Internet literature, with chief emphasis on their sensation-seeking or momentary entertainment value to the giver and recipient. Most participants are typically young; however, we report the case of a 50-year-old man who sustained chronic, painless radiculitis after he received an unanticipated wedgie of moderate force...

UNLABELLED: Why are some people strongly motivated by intense sensory experiences? Here we investigated how people encode the value of an intense sensory experience compared with economic reward, and how this varies according to stimulation-seeking preference. Specifically, we used a novel behavioral task in combination with computational modeling to derive the value individuals assigned to the opportunity to experience an intense tactile stimulus (mild electric shock). We then examined functional imaging data recorded during task performance to see how the opportunity to experience the sensory stimulus was encoded in stimulation-seekers versus stimulation-avoiders...

BACKGROUND: Impulsivity is often included as a risk factor in models of adolescent marijuana use behaviors; however, the magnitude of the association between impulsivity and marijuana use behaviors is variable across studies. The present study reviewed existent literature to 1) quantify the relationship between separable impulsivity-related traits and both marijuana use and negative marijuana consequences and 2) quantify the size of the effect of gender on these relationships. METHOD: Thirty-eight studies (41 independent samples) were meta-analyzed using a random effects model to examine the relationship between impulsivity traits and marijuana use behaviors...

OBJECTIVES: Anxiety sensitivity (AS) is associated with poor smoking cessation outcomes. One reason may be that smokers with high AS smoke differently (i.e., to manage negative affect and uncomfortable bodily sensations) than other smokers, leading to stronger addiction (due to an affect/sensation based and thereby highly variable rather than a regular smoking routine). Thus, we examined the relationship between AS and smoking variability in a group of treatment-seeking smokers. METHODS: Participants (N = 136; 52...

BACKGROUND: Data-driven approaches can capture behavioral and biological variation currently unaccounted for by contemporary diagnostic categories, thereby enhancing the ability of neurobiological studies to characterize brain-behavior relationships. METHODS: A community-ascertained sample of individuals (N = 347, 18-59 years of age) completed a battery of behavioral measures, psychiatric assessment, and resting-state functional magnetic resonance imaging in a cross-sectional design...

With the recent introduction of the Psychoactive Substances Bill in the United Kingdom, it is a useful time to retrospectively review the patterns of prevalence of the psychoactive products known as 'Legal Highs'. There has been emerging research and rapidly expanding political, public and media attention and awareness, yet comparatively little scientific discourse on the psychological aspects driving their consumption, beyond simply their legal status. This paper focuses on their usage patterns in the particularly vulnerable, but often-neglected period of young adulthood between the ages of 16-24, focussing on their prevalence, trends in pharmacology and psychological aspects of their usage and propensity for addiction...

Saliva is becoming an increasingly useful research material across multiple fields of inquiry, including biomedical, dental, psychological, nutritional, and food choice research. However, both the flow rate and protein composition of stimulated saliva differ as a function of the collection method. We hypothesized that the context in which a stimulus is presented to participants may alter salivation via top down cognitive effects and/or behavioral changes (i.e., spitting efficiency). We presented participants with one stimulus (commercially available green tea) in two distinct contexts, once where the tea was described as a food item ("tea") and once where it was described as a disgusting non-food item ("rabbit hair extract")...
