Historically, researchers have searched extensively for biological explanations regarding causes of psychopathy and its theorized developmental precursor, callous-unemotional (CU) traits (i.e., lack of empathy/guilt, shallow affect). In consequence, environmental factors such as exposure to negative life events and posttraumatic stress that often follows have been relatively overlooked. The present study tests whether exposure to negative life events and related symptoms of posttraumatic stress disorder (PTSD) are associated with CU traits among a sample of 238 incarcerated boys. Additionally, youth high on CU traits were disaggregated into primary and secondary variants based on the presence of anxiety to examine differences in their experiences of negative life events and PTSD symptoms. Results suggest that CU traits are significantly positively associated with both the experience of negative life events as well as PTSD symptomatology. Additionally, high-anxious youth scoring high on CU traits (secondary variant) were significantly more likely to report a history of negative life events and PTSD symptoms than were lower anxious boys scoring high on CU traits (primary type) and non-psychopathic youth. Thus, study findings warrant further exploration of how trauma might impact or maintain the development of CU traits over time and indicate that issues of differential diagnosis must be considered in order to more effectively tailor treatment for trauma-exposed CU youth. 相似文献

Although dependent and avoidant personality disorders are frequent in patient populations, there are only few studies in which the efficacy of psychotherapeutic interventions for these two personality disorders was reviewed. The purpose of this study was to examine whether psychodynamic short-term therapy based on the model of the cyclic maladaptive pattern (CMP) is effective for reducing the mental impairment of patients diagnosed with a dependent or an avoidant personality disorder. Data were collected via a self-report scale (Symptom-Checklist, SCL) and expert ratings by therapists [Global Assessment of Functioning (GAF) Scale and Severity of Impairment-Score (Beeinträchtigungsschwere-Score, BSS)]. In the study 20 patients received 25 sessions of outpatient therapy. Mental impairment decreased significantly from the beginning to the end of the therapy; moreover this decrease remained stable over a 2-year period following completion of the therapy. The findings show that psychodynamic short-term therapy can lead to an enduring improvement in the mental health of patients with a dependent or an avoidant personality disorder. 相似文献

Visual perception is an important component of environmental navigation. Previous research has revealed large individual differences in navigational strategies (i.e., the body’s kinesthetic and embodied approach to movement) and the perception of environmental surfaces (via distance estimations), but little research has investigated the potential relationship between these sources of individual variation. An important navigational strategy is the interaction between reliance on visual cues and vestibular or proprioceptive cues. We investigated the role of this navigational strategy in the perception of environmental surfaces. The results supported three embodied evolutionary predictions: Individuals who were most reliant on visual context (1) overestimated vertical surfaces significantly more, and (2) feared falling significantly more, than did those who were least reliant on visual context; and (3) all individuals had roughly accurate horizontal distance estimates, regardless of their navigational strategy. These are among the first data to suggest that individual differences in perception are closely related to the individual differences in navigation that derive from navigational risks. Variable navigational strategies may reflect variable capacities to perceive and navigate the environment. 相似文献

We present a single-subject prospective outcome study of a man with severe morphing fear and long history of OCD who was not helped by previous interventions, and who received an adapted form of cognitive behavior therapy (CBT) as part of this study. Treatment consisted of a cognitively focused approach tailored to address his fear of morphing and included developing a stronger sense of self-stability. We describe the details of the case, the treatment protocol, and the therapeutic outcomes as assessed over 36 weeks by questionnaires, rating scales, and semistructured interviews. The intervention was effective in eradicating the patient’s morphing fears and reducing other symptoms of OCD, anxiety, and depression. The presented case illustrates the need to appropriately conceptualize, assess, and address the specific nature of morphing fear symptoms in treatment. 相似文献

Family conflict is associated with longitudinal changes in insular‐striatal functional connectivity during adolescent risk taking under maternal influence

Maternal presence has marked effects on adolescent neurocognition during risk taking, influencing teenagers to make safer decisions. However, it is currently unknown whether maternal buffering changes over the course of adolescence itself, and whether its effects are robust to individual differences in family relationship quality. In the current longitudinal study, 23 adolescents completed a risk‐taking task under maternal presence during an fMRI scan before and after the transition to high school. Behavioral results reveal that adolescent risk taking increased under maternal presence across a one‐year period. At the neural level, we found that adolescents reporting higher family conflict showed longitudinal increases in functional coupling between the anterior insula (AI) and ventral striatum (VS) when making safe decisions in the presence of their mother, which was associated with increased real‐world risk taking. These findings show that individual differences in family relationship quality undermine effective development of AI‐VS connectivity resulting in increased risk taking. 相似文献

Adolescent decision‐making is highly sensitive to input from the social environment. In particular, adult and maternal presence influence adolescents to make safer decisions when encountered with risky scenarios. However, it is currently unknown whether maternal presence confers a greater advantage than mere adult presence in buffering adolescent risk taking. In the current study, 23 adolescents completed a risk‐taking task during an fMRI scan in the presence of their mother and an unknown adult. Results reveal that maternal presence elicits greater activation in reward‐related neural circuits when making safe decisions but decreased activation following risky choices. Moreover, adolescents evidenced a more immature neural phenotype when making risky choices in the presence of an adult compared to mother, as evidenced by positive functional coupling between the ventral striatum and medial prefrontal cortex. Our results underscore the importance of maternal stimuli in bolstering adolescent decision‐making in risky scenarios. 相似文献

This paper connects ideas from twentieth century Gestalt psychology, experiments in vision science, and Maurice Merleau-Ponty’s phenomenology of perception. I propose that when we engage in simple sensorimotor tasks whose successful completion is open, our behavior may be motivated by practical perceptual awareness alone, responding to invariant features of the perceptual field that are invisible to other forms of perceptual awareness. On this view, we see more than we think we see, as evidenced by our skillful bodily behavior. 相似文献

In intertemporal choices between smaller‐sooner (SS) and larger‐later (LL) rewards, five studies reveal that patience for the LL option is influenced by an interactive effect of the measurement units used to express wait time (large vs. small) and the type of the reward (hedonic vs. utilitarian). Specifically, larger time units boost patience, but more so when rewards are hedonic rather than utilitarian. In line with the numerosity heuristic, the effect of time units on patience is mediated by larger time units shrinking wait time perception. This effect arises because hedonic (vs. utilitarian) rewards promote a reliance on heuristics rather than systematic calculations. Therefore, a more calculative mindset diminishes the effect of units even for hedonic rewards and eliminates the hedonic‐utilitarian asymmetry. These results contribute to research on numerosity, intertemporal choice, and hedonic‐utilitarian differences, and offer a simple tool for practitioners to influence patience. 相似文献
