OPERANT CONTROL OF PATHOLOGICAL TONGUE THRUST IN SPASTIC CEREBRAL PALSY

Pathological tongue thrust (reverse swallowing) has been associated with neuromuscular disorders and linked to dental malocclusion, articulation problems, difficulty in eating, and excessive drooling. In this study, observable tongue thrust in a 10-year-old retarded male was modified during mealtime using a procedure consisting of differential reinforcement (presentation of food contingent upon tongue in) and punishment (gently pushing the tongue back into the mouth with a spoon). Results of a reversal design showed substantial decreases in tongue thrust and food expulsion, and a large increase in observed chewing. These data compared favorably with data obtained for other retarded persons not judged to be tongue thrusters; in addition, the objective results of the treatment program were substantiated via pre-post evaluations done by occupational and physical therapists. These findings suggest that operant techniques may be an effective means of treating tongue thrust and its associated problems, and that further development and evaluation of behavioral interventions may provide a desirable alternative to more intrusive surgical or mechanical procedures.

Are criminals better lie detectors? Investigating offenders' abilities in the context of deception detection

The present research examined lie detection abilities of a rarely investigated group, namely offenders. Results of the studies conducted thus far indicated a better performance of offenders compared to non‐offenders when discriminating between true and false messages. With two new studies, we aimed at replicating offenders' superior abilities in the context of deception detection. Results of Study 1 (N = 76 males), in contrast, revealed that offenders were significantly worse at accurately classifying true and false messages compared to non‐offenders (students). Results of Study 2 (N = 175 males) revealed that offenders' discrimination performance was not significantly different compared to non‐offenders (clinic staff). An internal meta‐analysis yielded no significant difference between offenders and non‐offenders, questioning the generalizability of previous findings.     

Collectives’ and individuals’ obligations: a parity argument

Individuals have various kinds of obligations: keep promises, don’t cause harm, return benefits received from injustices, be partial to loved ones, help the needy and so on. How does this work for group agents? There are two questions here. The first is whether groups can bear the same kinds of obligations as individuals. The second is whether groups’ pro tanto obligations plug into what they all-things-considered ought to do to the same degree that individuals’ pro tanto obligations plug into what they all-things-considered ought to do. We argue for parity on both counts.     

A Review on Spinal Muscular Atrophy: Awareness,Knowledge, and Attitudes

Spinal Muscular Atrophy (SMA) is one of the most common genetic causes of infant death. There is presently no cure, but the therapeutic pipeline is promising. Given the prevalence of SMA coupled with the potential for new treatment options, universal carrier screening, and newborn screening, we conducted a literature review of the awareness, knowledge, and attitudes held by the public and non-geneticist clinicians about various aspects of SMA. We then identify recommendations for targeting additional research, training, and educational efforts to increase awareness. In the limited available literature, we found that the public is generally unfamiliar with SMA but has favorable views of carrier and newborn screening. Clinicians also had limited understanding of SMA. Further research into knowledge and attitudes of healthcare providers and the general public will help develop a better understanding of education gaps and inform outreach efforts. These educational efforts are needed to complement the momentum as treatments are being developed and tested. Furthermore, professional societies are proposing routine carrier screening and SMA may achieve newborn screening status, which will change the SMA landscape for genetics professionals and families. Thus, it is important to explore knowledge and attitudes about SMA to allow us to prepare for when SMA attains higher public and clinician recognition.     

Non-violence as a Shifting Signifier on the Tibetan Plateau

In nomadic areas, Tibetans are wearing a new amulet, called an ‘amulet for peace’, depicting a globe with a dove flying above it. The dove carries a bodhi leaf in its mouth and a gold peace sign in its claws, combining Buddhist and global symbols for peace. However, the amulet is not being marshalled for Gandhian-style non-violent resistance nor world peace for that matter, but rather for something more local. This local cause is a campaign to end fighting over the grasslands, a sustained social problem in nomadic areas of eastern Tibet. The amulet for peace is a recent innovation, launched in 2012 as part of an ethical reform movement spearheaded by Larung Buddhist Academy, the largest monastic institution on the Tibetan plateau. This article discusses the latest developments in this emerging movement and, specifically, the significance of the amulet for peace and the discourses in which it is embedded.
