Maximizing the efficacy of interoceptive exposure by optimizing inhibitory learning: A randomized controlled trial

Cognitive-behavioral treatments for panic disorder (PD) emphasize interoceptive exposure (IE) to target anxiety sensitivity (AS) but vary considerably in its manner of delivery. This randomized controlled trial was conducted to compare the efficacy of the low-dose delivery of IE exercises often prescribed in treatment protocols to an intensive form of IE hypothesized to optimize inhibitory learning. Participants (N = 120) with elevated AS were randomly assigned to one of four single-session interventions: (a) low-dose IE as prescribed in Barlow and Craske's Panic Control Treatment, (b) low-dose IE without controlled breathing or a lengthy between-trial rest period, (c) intensive IE, or (d) expressive writing control. Compared to the other conditions, intensive IE produced significantly greater reductions in AS and fearful responding to a straw breathing task from pretreatment to posttreatment. Maintenance of gains during the follow-up period did not differ between conditions. Changes in fear toleration and negative outcome expectancies fully mediated the superior efficacy of intensive IE over low-dose IE. The two low intensity IE conditions produced particularly high rates of fear sensitization on between-trial and outcome variables. The findings suggest that the intensive delivery of IE exercises has the potential to improve the efficacy of exposure-based treatments for PD.     

Perception of Genuine and Masking Smiles in Children and Adults: Sensitivity to Traces of Anger

The authors examined children's and adults' sensitivity to traces of anger in masking smiles by presenting participants with short video excerpts of smiles that differed by the intensity of an anger component. Fifty-two children, aged 6 to 12 years, and 26 adults were asked to judge whether a stimulus person was really happy or pretending to be happy. Six- and 7-year-old children were found to be sensitive to traces of anger, but less so than older children and adults. Researchers found evidence of explicit knowledge of the emotion hidden in masking smiles only in adult participants.     

Preliminary Evaluation of Sleepwise Program for Children With Sleep Disturbance and Developmental Delay

Sleep disturbances are very prevalent in children with developmental delay. Parental-assisted behavioral strategies have been used effectively in school-aged children; however, multimodal treatment for preschool-aged children is lacking. The current study is a preliminary investigation of the effectiveness of a parent group program called Sleepwise designed for young children with developmental delay and incorporating behavioral, communicative, and sensory strategies. Six parents attended three workshop sessions and implemented individualized treatment plans. Initial results revealed significant posttreatment reductions in child sleep disturbances and behavioral problems, with high treatment acceptability ratings by parents. Outcomes were generally maintained at 1-month follow-up.     

High magnetic field induction of the formation of twinned dendrites during directional solidification of Al–4.5wt%Cu alloy

It is reported that the application of a high magnetic field is capable of inducing the formation of twinned dendrites during directional solidification of Al–4.5wt%Cu alloy. Numerical results reveal that a unidirectional thermoelectric magnetic force acts on tilted dendrites during directional solidification under a magnetic field. This force should be responsible for the formation of twinned dendrites. The work may initiate a new method for inducing twinned dendrites in Al-based alloys via an applied high magnetic field during directional solidification.     

Activating and Enlivening Ourselves and Our Patients: Commentary on Paper by Susan H. Sands

In my response to Sands's paper I offer comments on four aspects of clinical work with dissociation: the sensory power of language, the evocation of the analyst's own dissociated experience and internal growth, the question of the relationship between dissociation and unconscious experience, and the different responses evoked by patients who are at different points on the path toward association.     

The Particularities of Form: Reply to Commentary

In this brief reply to Bollas's commentary on our paper about his work, the cycles of intersubjective dialogue endlessly sustaining should be apparent. We begin with an example of the form—content distinction and attempt to use it as a springboard for further disentangling some of the nuances of Bollas's intersubjective theorizing. Bollas's emphasis on form over content as a means of conceptualizing the analyst's contribution to the analytic process is indeed compelling. We all know from both sides of the couch the profoundly different meanings and messages that an analyst's mien invites: whether she's abrupt, verbose, meditative, tranquil. Yes, the medium is the message, and, thus, whether the analyst conveys a message through the effects of form that Bollas points out, such as “We have all the time you need for the nuances of unconscious figuring” versus “This is hot—we hafta figure it out now” surely does have an effect on the psychic material produced in the analytic process. We go on to add to Bollas's discussion of form by considering the particularities of form and how these too affect the analytic process.
