We use the Reinforcement Sensitivity Theory (RST) of Reinforcement Sensitivity Theory personality to measure approach, avoidance, and inhibition dispositions, as well as measures of Callous- Psychopathy Unemotional and psychopathic personalities. In an international sample of 454 respondents, results showed that Callous-unemotional traits RST, psychopathic personality, and callous-unemotional measures accounted for different aspects of risk-taking Risk-taking behaviour. Specifically, traits associated with ‘fearlessness’ related more to ‘prosocial’ (recreational and social) risk-taking, whilst traits associated with ‘impulsivity’ related more to ‘antisocial’ (ethical and health) risk-taking. Further, we demonstrate that psychopathic personality may be demonstrated by combining the RST and callous- unemotional traits (high impulsivity, callousness, and low fear). Overall this study showed how impulsive, fearless and antisocial traits can be used in combination to identify pro- and anti-social risk-taking behaviours; suggestions for future research are indicated. 1. -
Relaxation Techniques? a Substantial Amount of Research Has Been Done on Relaxation Techniques
U.S. Department of Health & Human Services National Institutes of Health Relaxation Techniques © Thinkstock What’s the Bottom Line? How much do we know about relaxation techniques? A substantial amount of research has been done on relaxation techniques. However, for many health conditions, the number or size of the studies has been small, and some studies have been of poor quality. What do we know about the effectiveness of relaxation techniques? Relaxation techniques may be helpful in managing a variety of health conditions, including anxiety associated with illnesses or medical procedures, insomnia, labor pain, chemotherapy-induced nausea, and temporomandibular joint dysfunction. Psychological therapies, which may include relaxation techniques, can help manage chronic headaches and other types of chronic pain in children and adolescents. Relaxation techniques have also been studied for other conditions, but either they haven’t been shown to be useful, research results have been inconsistent, or the evidence is limited. What do we know about the safety of relaxation techniques? Relaxation techniques are generally considered safe for healthy people, although there have been a few reports of negative experiences, such as increased anxiety. People with serious physical or mental health problems should discuss relaxation techniques with their health care providers. What Are Relaxation Techniques? Relaxation techniques include a number of practices such as progressive relaxation, guided imagery, biofeedback, self-hypnosis, and deep breathing exercises. The goal is similar in all: to produce the body’s natural relaxation response, characterized by slower breathing, lower blood pressure, and a feeling of increased well-being. Meditation and practices that include meditation with movement, such as yoga and tai chi, can also promote relaxation. -
Fact Sheet - Reinforcement
FACT SHEET - REINFORCEMENT Positive Reinforcement Because many children with autism have difficulty with communication, play skills, and socialization, it is often difficult to motivate them to engage in activities that incorporate these skills. Positive reinforcement can provide additional motivation to help shape and increase developmentally approriate behaviors. A positive reinforcer is anything that is added following a behavior that increases the likelihood of the behavior occuring again in the future.

Huppert, PhD Department of Psychology, The Hebrew University of Jerusalem, Jerusalem, Israel Abstract: Cognitive behavioral therapy (CBT) is a set of treatments that focus on altering thoughts, sensations, emo- tions and behaviors by addressing identified maintenance mechanisms such as distorted thinking or avoidance. The current article describes the history of CBT and provides a description of many of the basic techniques used in CBT. These include: psychoeducation, self-monitoring, cognitive restructuring, in vivo exposure, imaginal exposure, and homework assignments.

L. Ross, S. R. Corr, P. J. Introduction Due to researchers’ differing opinions regarding the construct of psychopathy, the distinction between primary and secondary psychopathy, though it has long been recognized to exist, has yet to be fully understood. This distinction, originally proposed by Karpman (1941, 1948), suggests two separate etiologies leading to psychopathy. Whereas primary psychopathy stems from genetic influences resulting in emotional deficits, secondary psychopathy is associated with environmental factors such as abuse (Lee & Salekin, 2010). Additionally, primary psychopathy is characterized by lack of fear/anxiety, secondary psychopathy is thought more to represent a vulnerability to experience higher levels of negative affect in general (Vassileva, Kosson, Abramowitz, & Conrad, 2005). -
Trauma-Focused Group Music and Imagery with Women Suffering From
Approaches: An Interdisciplinary Journal of Music Therapy | Special Issue 9 (2) 2017 SPECIAL ISSUE Guided Imagery and Music: Contemporary European perspectives and developments Article Trauma-focused group music and imagery with women suffering from PTSD/complex PTSD: A feasibility study Gabriella Rudstam, Ulf Elofsson, Hans Peter Søndergaard, Lars Ole Bonde & Bolette Daniels Beck ABSTRACT Women who have been exposed to physical, psychological and/or sexual abuse, often with a history of childhood abuse and neglect, frequently suffer from post-traumatic stress disorder (PTSD) or complex post- traumatic stress disorder (CPTSD). However, the evidence-based treatments recommended for this population help only 50%, so there is a need to investigate complementary methods. In this study one such promising method has been explored: trauma-focused Group Music and Imagery (GrpMI). In a non- randomised clinical setting the feasibility of GrpMI and the suitability of chosen measurements were explored. Ten participants with PTSD/CPTSD were enrolled in the pilot study, five in each group. All participants completed the treatment. The primary outcome was symptoms of PTSD measured at pre-, post- and follow-up. The secondary outcomes were dissociation and quality of life. The results showed a decrease in PTSD and dissociative symptoms, and an increase in quality of life following treatment. This tendency was maintained at follow-up. An analysis of individual, semi-structured interviews with the participants after the termination of the treatment showed that the participants found the group treatment helpful and acceptable. Since the findings indicate that trauma-focused GrpMI has a positive effect on the psychological health of the women, a larger randomised controlled study is needed. -

Cognitivebehavioral Methods in Highconflict Divorce
COGNITIVE-BEHAVIORAL METHODS IN HIGH-CONFLICT DIVORCE: SYSTEMATIC DESENSITIZATION ADAPTED TO PARENT–CHILD REUNIFICATION INTERVENTIONS Benjamin D. Garber Children who are triangulated into their parents’ conflicts can become polarized, aligning with one parent and rejecting the other. In response, courts often order families to engage mental health professionals to provide reunification interventions. This article adapts empirically established systematic desensitization and flooding procedures most commonly used to treat phobic children as possible components of a larger family systems invention designed to help the polarized child develop a healthy relationship with both parents. Strengths and weaknesses of these procedures are discussed and illustrated with case material. Key Points for the Family Court Community: • Family law and psychology agree that children should have the opportunity to enjoy a healthy relationship with both parents • Adult conflict can polarize a child’s relationships, including rejection of one parent • Existing clinical and forensic “reunification” strategies often prove inadequate • Reliable and valid cognitive behavioral methods can be adopted to facilitate this process • A cognitive-behavioral “exposure-based” reunification protocol is discussed Keywords: Alienation; Custody Reversal; Desensitization; Enmeshment; Estrangement; Exposure; Flooding; High-Conflict Divorce; Parent–Child Polarization; Psychotherapy; Reconciliation; and Reunification. “The child develops an anxious and phobic-like response . a mutually escalating cycle of fear and anxiety develop between the child and the alienating parent; the more upset the child is, the more protective and concerned the parent is, which in turn escalates the child’s reactions and so on. Learning theory demonstrates that the correction (extinction) of the avoidance is extremely difficult and requires exposure and systematic desensitization to the avoided circumstance or feared object.” (B.J. -
Behavior Therapy
Behavior Therapy By- Sweta Pathak INTRODUCTION • Therapy -Treatment intended to relieve or heal a disorder: "cancer therapies". 0R • The treatment of mental or psychological disorders by psychological means: like- "he is currently in therapy"; "therapy sessions". • Psychotherapy -The treatment of mental disorder by psychological rather than medical means Behaviour therapy Behavior therapy (BT) is based on behaviorism utilizes a philosophy of naturalism and the spirit of logical positivism. Behaviorism is a reaction to psychodynamic thought and philosophy, particularly to its introspection and its hypothesized inner, human realities such as drives, instincts, ego, id, superego, repression etc. Like Freudian psychoanalysis, behaviorism is Darwinian in outlook. A major assumption of this- Abnormal behavior is acquired in the same way as normal behavior-that is by learning. Techniques of BT Guided exposure therapy-is intended to treat anxiety disorders and involves the exposure to the feared object or context without any danger in order to overcome their anxiety. Or It involves presenting the person with a harmless but fear evoking stimuli until the stimuli no longer elicit fear. Exposure is a form of therapy commonly used in treating phobias and other anxiety disorders. Exposure-based therapy may be effective in preventing the progression from acute stress disorder to post-traumatic stress disorder. During exposure therapy, the person is presented with a fear-evoking stimuli in a controlled, prolonged fashion, until the fear diminishes. Treatment is collaborative, with the patient and therapist working together to decide how and when exposure will take place. Exposure duration depends upon – the type of feared stimuli and the severity of the person’s fears. -
Healing Factors in Guided Affective Imagery: a Qualitative Meta-Analysis
Healing Factors in Guided Affective Imagery: A Qualitative Meta-Analysis Submitted in Partial Fulfillment Of the Requirements for the Degree of Doctor of Philosophy with a concentration in Psychology and a specialization in Counseling and Psychotherapy at the Union Institute & University Cincinnati, Ohio Elaine Sue Kramer April 3, 2010 Core Faculty: Lawrence J. Ryan, PhD i Abstract This qualitative meta-analysis compares and contrasts European and American approaches to Guided Affective Imagery (GAI). From a comparative review of literature of the European and American approaches, it is observed that there are noteworthy differences in how GAI is understood in theory and applied in practice. In the United States, GAI is not perceived as a method of deep psychotherapeutic intervention for neurotic disorders by most practitioners. In Europe, GAI is one of the more prevalent intervention techniques that has been reported to be effective in many disorders. Secondly, this meta-analysis seeks to identify the essential healing elements of GAI as they are implemented in psychotherapy. Twelve factors are identified from the literature. Of fundamental clinical importance is the activation of a patient’s “resources,” the positive characteristics of an individual that can be accessed to reinforce the patient’s ability to deal with a past traumatic experience. GAI provides the imagery context by which the patient may re-experience the trauma. The therapist assists by encouraging the patient to repeatedly utilize internal resources to confront the fearful event. Lasting relief may be conceptualized as repeated resource activation leading to a biochemically-induced remapping at synaptic sites away from the limbic-centered, emotion-based neural path associated with the traumatic event toward the prefrontal cortex-centered, cognitive-based path of appropriate behavior. -
