SEPARATE AND COMBINED EFFECTS OF VISUAL SCHEDULES AND EXTINCTION PLUS DIFFERENTIAL REINFORCEMENT ON PROBLEM BEHAVIOR OCCASIONED BY TRANSITIONS

The separate and combined effects of visual schedules and extinction plus differential reinforcement of other behavior (DRO) were evaluated to decrease transition‐related problem behavior of 2 children diagnosed with autism. Visual schedules alone were ineffective in reducing problem behavior when transitioning from preferred to nonpreferred activities. Problem behavior decreased for both participants when extinction and DRO were introduced, regardless of whether visual schedules were also used.     

Being Emotional about the Past: On the Nature and Role of Past‐Directed Emotions*

We sometimes experience emotions which are directed at past events (or situations) which we witnessed at the time when they occurred (or obtained). The present paper explores the role which such “autobiographically past‐directed emotions” (or “APD‐emotions”) play in a subject's mental life. A defender of the “Memory‐Claim” holds that an APD‐emotion is a memory, namely a memory of the emotion which the subject experienced at the time when the event originally occurred (or the situation obtained) towards which the APD‐emotion is directed. On this view, APD‐emotions might play an important role in our acquiring knowledge about our own past emotions, which renders the view rather attractive. However, as I show in the present paper, none of the various possible versions of the Memory‐Claim are tenable. This leaves us with the “Universal‐New‐Emotion‐Claim”, according to which all APD‐emotions are new emotional responses to the past events (or situations) towards which the relevant APD‐emotions are directed. Further consideration of the “Universal‐New‐Emotion‐Claim” shows that while APD‐emotions do not play the epistemological role they could have played had some version of the Memory‐Claim turned out to be true, a subject's APD‐emotions nevertheless do play a vital role in a subject's mental life: they help the subject to develop a balanced sense of self.     

Further evaluation of response interruption and redirection as treatment for stereotypy

The effects of 2 forms of response interruption and redirection (RIRD)-motor RIRD and vocal RIRD-were examined with 4 boys with autism to evaluate further the effects of this intervention and its potential underlying mechanisms. In Experiment 1, the effects of motor RIRD and vocal RIRD on vocal stereotypy and appropriate vocalizations were compared for 2 participants. In Experiment 2, the effects of both RIRD procedures on both vocal and motor stereotypy and appropriate vocalizations were compared with 2 additional participants. Results suggested that RIRD was effective regardless of the procedural variation or topography of stereotypy and that vocal RIRD functioned as a punisher. This mechanism was further explored with 1 participant by manipulating the schedule of RIRD in Experiment 3. Results were consistent with the punishment interpretation.     

Reinforcement Delay Fading During Differential Reinforcement of Communication: The Effects of Signals on Response Maintenance

Signals during delays to reinforcement may lessen reductions in responding that typically occur when there is a delay between a response and its reinforcer. Sparse applied research has been devoted to understanding the conditions under which responding may be maintained when delays to reinforcement are introduced. We evaluated the extent to which providing signals during delay fading affected responding in the context of differential reinforcement of communication responses. Three individuals were exposed to gradually increasing signaled and unsignaled reinforcement delays in multiple‐schedule and/or withdrawal designs. Results for 2 of 3 participants suggested that (a) the presence of signals facilitated response maintenance under delayed reinforcement and (b) coordinated basic and applied research may advance both conceptual understanding and clinical outcomes of delayed reinforcement.     

Treating Prepartum Depression to Improve Infant Developmental Outcomes: A Study of Diabetes in Pregnancy

Whether and how the co-occurrence of depression and diabetes in pregnancy may worsen infant development has not been reported. Pregnant women with diabetes and with (n?=?34) or without (n?=?34) major depressive disorder (MDD) were followed during pregnancy and 6-months postpartum. The MDD subset received randomly assigned treatment with cognitive behavior therapy (CBT) or supportive counseling (SC). Depression severity was measured with the Beck Depression Inventory (BDI); infant developmental outcomes were measured with the Bayley Scales of Infant Development (BSID) and its Behavior Rating Scale (BRS). Infants of women with MDD had lower BRS scores (p?=?.02). Reduction in depression scores was associated with better infant outcomes on the BSID and BRS (p values <.03). These preliminary findings suggest depression occurring in pregnant women with diabetes is associated with poorer infant development and improvement in prepartum depression is associated with improvement in measures of infant development.
