Verbal Sexual Coercion and Perceived Victim Responsibility: Mediating Effects of Perceived Control

Verbal coercion involves unwanted sexual penetration compelled by psychological pressure. It was hypothesized that, to the degree that verbal coercion is seen as controllable, victims may be held more responsible. Two samples of US undergraduates rated perceptions of hypothetical sexual coercion scenarios. In Study 1, participants (N = 120) read scenarios of either verbal coercion or rape by a male dating partner. Participants perceived verbal coercion as more controllable than rape, which accounted for the greater responsibility attributed to verbal coercion victims. In Study 2, participants (N = 275) read scenarios involving either male-to-female or female-to-male verbal coercion. Participants perceived female-to-male coercion as more controllable, which accounted for the greater responsibility attributed to a verbally coerced man.     

The central nucleus of the amygdala is essential for acquiring and expressing conditional fear after overtraining

The basolateral complex of the amygdala (BLA) is critical for the acquisition and expression of Pavlovian fear conditioning in rats. Nonetheless, rats with neurotoxic BLA lesions can acquire conditional fear after overtraining (75 trials). The capacity of rats with BLA lesions to acquire fear memory may be mediated by the central nucleus of the amygdala (CEA). To examine this issue, we examined the influence of neurotoxic CEA lesions or reversible inactivation of the CEA on the acquisition and expression of conditional freezing after overtraining in rats. Rats with pretraining CEA lesions (whether alone or in combination with BLA lesions) did not acquire conditional freezing to either the conditioning context or an auditory conditional stimulus after extensive overtraining. Similarly, post-training lesions of the CEA or BLA prevented the expression of overtrained fear. Lastly, muscimol infusions into the CEA prevented both the acquisition and the expression of overtrained fear, demonstrating that the effects of CEA lesions are not likely due to the destruction of en passant axons. These results suggest that the CEA is essential for conditional freezing after Pavlovian fear conditioning. Moreover, overtraining may engage a compensatory fear conditioning circuit involving the CEA in animals with damage to the BLA.     

Trait Anger and Axis I Disorders: Implications for REBT

Anger has a prominent role in basic theories of emotion. And while many psychiatric disorders can be conceived of as emotional disorders (e.g., depressive disorders, anxiety disorders), there are no disorders for which anger is the cardinal feature. We analyzed diagnostic data on 1,687 (as later) psychiatric outpatients and looked at the co-occurrence of high trait anger (as assessed by criterion 8 of Borderline Personality Disorder) and Axis I disorders, and Borderline and Antisocial Personality Disorders. The purpose was to examine whether dysfunctional anger met criteria necessary to be considered a valid diagnostic category. Results showed that high trait anger was not fully accounted for by any particular Axis I diagnosis, or any set of Axis I diagnoses, or by the combination of Axis I diagnoses and Borderline and Antisocial PDs. Trait anger also accounted for significant amounts of unique variance in several indicators of psychiatric impairment and psychosocial functioning. We describe the anger disorder diagnoses of Eckhardt and Deffenbacher (Anger disorders: Definition, diagnosis and treatment. Taylor & Francis, Bristol, PA, 1995), and discuss the implications of those diagnoses for the practice of REBT and CBT.

The Pictorial Fire Stroop: A Measure of Processing Bias for Fire-Related Stimuli

Fire interest is a risk factor for firesetting. This study tested whether a fire-specific emotional Stroop task can effectively measure an information-processing bias for fire-related stimuli. Clinic-referred and nonreferred adolescents (aged 13–16 years) completed a pictorial “Fire Stroop,” as well as a self-report fire interest questionnaire and several control tasks. Results showed (a) comparatively greater fire-specific attentional bias among referred adolescent firesetters, (b) a negative relationship between Fire Stroop attentional bias and self-reported fire interest, and (c) positive correspondence between Fire Stroop attentional bias and self-reported firesetting frequency. These findings suggest that instruments that measure an automatic bias for fire-specific stimuli may usefully supplement self-report measures in the assessment and understanding of firesetting behavior.     

Illness representations and matching labels with symptoms

Three studies are reported that show that health-relevant information (e.g., blood pressure [BP] or symptoms) initiates an active cognitive search process that results in the construction of an illness representation. Study 1 showed that informing subjects that their BP was elevated affected two attributes of illness representation: identity (label and symptoms), and time line or expected chronology of the health threat. Subjects given a high-BP reading reported symptoms commonly associated with high BP, especially if they attributed the high-BP reading to stress. Study 2 showed that the active search process uses causal information (a third attribute of representations) to give meaning to symptoms. Specifically, subjects used environmental cues to interpret whether familiar, unfamiliar, and ambiguous symptoms were due to illness or to stress. In Study 3 we showed that the constructive process, initiated by a high-BP reading, is directed by prior beliefs about the time line for developing high BP and by the presence of external cues about the stressfulness of the subject's daily life. Subjects who believed BP was labile and that they were under high daily stress or who believed BP was stable and that they were under low daily stress reported more symptoms. The significance of these findings for understanding how people process diagnostic labels and symptom information involved in the construction of illness representations is discussed.     

Germ-line gene therapy and the clinical ethos of medical genetics

Although the ability to perform gene therapy in human germ-line cells is still hypothetical, the rate of progress in molecular and cell biology suggests that it will only be a matter of time before reliable clinical techniques will be within reach. Three sets of arguments are commonly advanced against developing those techniques, respectively pointing to the clinical risks, social dangers and better alternatives. In this paper we analyze those arguments from the perspective of the client-centered ethos that traditionally governs practice in medical genetics. This perspective clarifies the merits of these arguments for geneticists, and suggests useful new directions for the professional discussion of germ-line gene therapy. It suggests, for example, that the much discussed prospect of germ-line therapy in human pre-embryos may always be more problematic for medical genetics than adult germ-line interventions, even though the latter faces greater technical difficulties.
