Remote treatment of sleep‐related trichotillomania and trichophagia

We used a biobehavioral treatment consisting of melatonin and a standardized bed and wake time to decrease one girl's head and mouth touches associated with sleep‐related trichotillomania and trichophagia. We remotely coached the girl's caregiver to implement all procedures and monitored response to treatment using a DropCam Pro video camera equipped with night‐vision capabilities. Head and mouth touches decreased, and her sleep pattern improved with the combination of treatment strategies. We discuss our use of a novel mode of service delivery to treat sleep‐related problem behavior.     

Further evaluation of differential exposure to establishing operations during functional communication training

Recent research findings (DeRosa, Fisher, & Steege, 2015 ) suggest that minimizing exposure to the establishing operation (EO) for destructive behavior when differential reinforcement interventions like functional communication training (FCT) are introduced may produce more immediate reductions in destructive behavior and prevent or mitigate extinction bursts. We directly tested this hypothesis by introducing FCT with extinction in two conditions, one with limited exposure to the EO (limited EO) and one with more extended exposure to the EO (extended EO) using a combined reversal and multielement design. Results showed that the limited‐EO condition rapidly reduced destructive behavior to low levels during every application, whereas the extended‐EO condition produced an extinction burst in five of six applications. We discuss these findings in relation to the effects of EO exposure on the beneficial and untoward effects of differential reinforcement interventions.     

Prevalence of resurgence of destructive behavior when thinning reinforcement schedules during functional communication training

Functional communication training is a well‐established treatment for socially reinforced destructive behavior that typically includes differential reinforcement of the functional communication response (FCR) in combination with extinction of destructive behavior. However, when the schedule of reinforcement for the FCR is thinned, destructive behavior may resurge (e.g., Greer, Fisher, Saini, Owen, & Jones, 2016). Currently, data are unavailable on the prevalence and characteristics of resurgence during reinforcement schedule thinning. In this study, we evaluated the prevalence of resurgence during reinforcement schedule thinning on a per‐case and per‐schedule‐step basis and also evaluated the magnitude of resurgence in relation to the functions of destructive behavior. We observed resurgence in 19 of the 25 (76%) applications of reinforcement schedule thinning. In some cases, the magnitude of resurgence exceeded the mean levels of destructive behavior observed in baseline. We discuss these results relative to prior translational and applied research on resurgence.     

Exploring phenomenological interviews: questions,lessons learned and perspectives

Phenomenology and the Cognitive Sciences -     

Heidegger's Generative Thesis

Abstract: For William Blattner, Heidegger's phenomenology fails to demonstrate how a nonsuccessive temporal manifold can ‘generate’ the appropriate sequence of world‐time Nows. Without this he cannot explain the ‘derivative’ status of ordinary time. In this article I show that it is only Blattner's reconstruction that makes failure inevitable. Specifically, Blattner is wrong in the way he sets out the explanatory burden, arguing that the structure of world‐time must meet the traditional requirements of ordinary time logic if the derivation is to succeed. He takes this to mean: mundane ‘tasks’, the contents of world‐time nows, must form a transitive series, importing back into world‐time the very structure that Heidegger says is derived by its levelling‐off. I argue, instead, that world‐time nows, seen at the level of lived content, can be quite ‘irrational’ but this is perfectly consistent with the generative thesis. Adapting Blattner's useful suggestion that temporality is sequence building or ‘iterative’ I show that iteration does not manifest itself at the level of tasks but at the ‘existential’ level of my involvement in a task. Depriving that involvement of its expressive content is what accounts for the levelling‐off of the world‐time now and thus the derivation of the ordinary concept of time.     

Detecting true and false opinions: The Devil's Advocate approach as a lie detection aid

We examined the efficacy of a new approach to detect truths and lies in expressing opinions: the Devil's Advocate approach. Interviewees are first asked an opinion eliciting question that asks participants to argue in favour of their personal view. This is followed by a Devil's Advocate question that asks participants to argue against their personal view. People normally think more about reasons that support rather than oppose their opinion. Therefore we expected truth tellers to provide more information and shorter latency times in their responses to the opinion eliciting question than to the Devil's Advocate question. Liars are expected to reveal the opposite pattern as the Devil's Advocate question is more compatible with their beliefs than is the opinion eliciting question. In Experiment 1, we interviewed seventeen truth tellers and liars via the Devil's Advocate approach and measured the difference in number of words and latency times to the two questions. Our hypotheses were supported. In Experiment 2, 25 observers were shown these interviews, and made qualitative judgements about the statements. Truth tellers' opinion eliciting answers were seen as more immediate and plausible and revealed more emotional involvement than their Devil's Advocate answers. No clear differences emerged in liars' answers to the two types of question. We conclude that the Devil's Advocate approach is a promising lie detection approach that deserves attention in future research.     

Diagnostic Comorbidity in Adults With Generalized Anxiety Disorder: Impact of Comorbidity on Psychotherapy Outcome and Impact of Psychotherapy on Comorbid Diagnoses

The current study examined the impact of comorbidity on cognitive and behavioral therapies for generalized anxiety disorder (GAD) as well as the impact of these therapies on diagnoses comorbid to GAD. Seventy-six treatment-seeking adults with principal diagnoses of GAD received 14 sessions of therapy. Most (n = 46; 60.5%) of the sample had at least one comorbid diagnosis. Although the presence of comorbid diagnoses was associated with greater severity of GAD symptoms at pretreatment, greater severity of comorbid major depression, simple phobia, and social phobia was associated with greater change in symptoms of GAD in response to treatment, with no effect on maintenance of gains during a 2-year follow-up. Further, psychotherapy for principal GAD led to a reduction in number of comorbid diagnoses and in severity of social phobia, simple phobia, and major depression at posttreatment. At 2-year follow-up severity of social and simple phobia remained below pretreatment levels, whereas severity of depression was no longer significantly below pretreatment levels. These results suggest that although people with comorbid disorders enter treatment with more severe GAD symptomatology, they demonstrate greater change, and therefore such comorbidity does not diminish the efficacy of cognitive and behavioral therapies for GAD. In addition, the impact of these treatments for GAD may generalize to reduced severity of simple phobia, social phobia, and major depression; however, gains in severity of major depression are not maintained.     

Heidegger and the narrativity debate

One unresolved dispute within Heidegger scholarship concerns the question of whether Dasein should be conceived in terms of narrative self-constitution. A survey of the current literature suggests two standard responses. The first correlates Heidegger’s talk of authentic historicality with that of self-authorship. To the alternative perspective, however, Heidegger’s talk of Dasein’s existentiality, with its emphasis on nullity and unattainability, is taken as evidence that Dasein is structurally and ontologically incapable of being completed via any life-project. Narrativity imports into Being and Time commitments concerning temporality, selfhood, and ethics, which Heidegger rejects. Although both positions find good exegetic support for their conclusions, they can’t both be right. In this article, I navigate a path between these two irreconcilable positions by applying insights derived from recent debates within Anglo-American literature on personal identity. I develop an alternative thesis to Narrativism, without rejecting it outright, by arguing that Dasein can be analysed in terms of what I call “narratability conditions.” These allow us to make sense of the prima facie paradoxical notion of “historicality without narrativity.” Indeed, rather than reconciling the two standard positions, I hold that the tension between them says something important about Dasein’s kind of existence. Thus I conclude that while the narrativist question “Who ought I to be?” is perfectly legitimate within limits, what the existential analysis of the limits on narratability reveals is that no answer to this question can ever be definitive.
