Selected AbstractsGender-specific disruptions in emotion processing in younger adults with depression,DEPRESSION AND ANXIETY, Issue 2 2009Sara L. Wright Ph.D. Abstract Background: One of the principal theories regarding the biological basis of major depressive disorder (MDD) implicates a dysregulation of emotion-processing circuitry. Gender differences in how emotions are processed and relative experience with emotion processing might help to explain some of the disparities in the prevalence of MDD between women and men. This study sought to explore how gender and depression status relate to emotion processing. Methods: This study employed a 2 (MDD status) × 2 (gender) factorial design to explore differences in classifications of posed facial emotional expressions (N=151). Results: For errors, there was an interaction between gender and depression status. Women with MDD made more errors than did nondepressed women and men with MDD, particularly for fearful and sad stimuli (Ps <.02), which they were likely to misinterpret as angry (Ps <.04). There was also an interaction of diagnosis and gender for response cost for negative stimuli, with significantly greater interference from negative faces present in women with MDD compared to nondepressed women (P=.01). Men with MDD, conversely, performed similarly to control men (P=.61). Conclusions: These results provide novel and intriguing evidence that depression in younger adults (<35 years) differentially disrupts emotion processing in women as compared to men. This interaction could be driven by neurobiological and social learning mechanisms, or interactions between them, and may underlie differences in the prevalence of depression in women and men.

[source] The microstructure of ethanol drinking: genetic and behavioral factors in the control of drinking patternsADDICTION, Issue 8s2 2000Herman H. Samson The concept of craving can be examined in many different ways, depending upon the individual definition of the term. Using the concepts and procedures of regulatory behavior analysis, this review explores behavioral studies in rats that have some relationships to some of the possible processes that underlie the concept of craving in humans. Data are reviewed from studies employing both limited and continuous access to ethanol, examining the role of access availability, ethanol initiation, response cost, time since last access, composition of the ethanol containing solution and genetic selection. From this review, it is clear that rat models can implicate important variables involved in the control of human alcohol consumption. [source] A comparison of two multicomponent procedures to increase food consumptionBEHAVIORAL INTERVENTIONS, Issue 2 2005Scott D. Buckley We compared two procedural variations of response cost (RC) of preferred materials to increase mouth clean in a five-year-old boy diagnosed with autism. Noncontingent presentation of preferred materials (NCR) was compared to differential reinforcement of alternative behavior (DRA) when returning preferred materials once they have been removed for refusal or expulsion of food. Results indicated that both procedures increased swallowing and reduced problem behavior; however, NCR,+,RC was superior to DRA,+,RC with respect to overall mean and initial treatment measures.

Hagopian In contrast to inherently dangerous behaviors such as self-injury and aggression, some behaviors are problematic because of the context in which they occur. In the current study, we report on a boy who engaged in dropping to the floor both excessively and at inappropriate times. During the functional analysis, dropping occurred across all conditions, suggesting that it was either multiply maintained or maintained by automatic reinforcement. Treatment involved the use of discriminative stimuli and differential reinforcement with response cost to teach the client when dropping to the floor was and was not appropriate.

[source] Effects of DRL and DRL combined with response cost on perseverative verbal behavior of an adult with mental retardation and obsessive compulsive disorderBEHAVIORAL INTERVENTIONS, Issue 1 2001George Kostinas Although there has been increased interest in the identification and diagnosis of obsessive compulsive disorder (OCD) in people who have developmental disabilities, clinical research has been reported infrequently. The present single-case study evaluated the effects from systematic behavioral intervention with a 26-year-old man who had moderate mental retardation, OCD, and exhibited perseverative verbalizations. Verbalizations were reduced when the man gained access to preferred activities contingent upon a low response frequency (DRL: differential reinforcement of low-rate responding). The behavior was reduced further when a DRL contingency was implemented in the form of a response cost procedure. The implications of these findings for the treatment of OCD in people with developmental disabilities are discussed. Copyright © 2001 John Wiley & Sons, Ltd. [source] | ||||||||||
