Influence of the intensity of NaCl solutions on adaptation degree and recovery time course

The degree of adaptation and the time course of recovery after adaptation to NaCl solutions of various intensities were examined by magnitude estimation and simple sensory reaction time using a test stimulus of constant intensity. The results show that the degree of adaptation increased with the adapting concentration following a negatively accelerated function. Similarly, all recovery curves were negatively accelerated functions of the recovery time. The relation between the recovery constant (time necessary to attain two-thirds of normal responsivity) and adapting concentration approximates with both criteria more or less a linear function. Thus the recovery constant is a positively accelerated function of the degree of adaptation. The relationship between concentration and degree of adaptation can be approximated by Beidler’s equation of taste stimulation, while the time course of recovery can be expressed by an exponential equation that can also be related to Beidler’s theory. The two criteria used showed similar deteriorating effects of taste adaptation, indicating that reaction time can also be a useful criterion of the level of sensory responsivity.     

Logics with the Qualitative Probability Operator

The paper presents several strongly complete axiomatizationsof qualitative probability within the framework of probabilisticlogic. We show that in the proposed semantics qualitative probabilitiesare characterized by probability functions, so they also arecomparative probabilities.     

Potassium gymnemate and the sweet and bitter taste provoked electrically

The sweetness or bitterness of taste solutions of saccharin and quinine may be blocked, while the sweetness or bitterness evoked by electrical stimulation of the tongue by cathodal polarization is unchanged. Electrical taste stimulation apparently bypasses the most peripheral process by which taste solutions elicit sweet and bitter and thus acts directly on the receptor and/or its afferent nerve terminals.     

Time course of recovery from gustatory adaptation to NaCl

Recovery from adaptation to NaCl was tested by comparing some relevant parameters of response to the adapting and test stimuli separated by different recovery intervals. The time course of response was determined using magnitude estimations and using the flow chamber for stimulus delivery. The course of recovery for all parameters used was a negatively accelerated function of the rest time, but the recovery rate of different parameters did not prove to be equal. Recovery was fastest for the initial maximum taste magnitude, followed by the time needed for the taste to disappear. The taste effect summed over time and the time required for the taste magnitude to decrease to 30% of its preadapted maximum were the slowest to recover. Although the recovery process proceeded at a rapid rate during the initial period, all parameters remained depressed over a rather long period.     

Behavioral interventions may prolong remission in patients with inflammatory bowel disease

Inflammatory Bowel Diseases (IBDs) are chronic, relapsing and remitting gastrointestinal conditions with no known cure. Previous studies have linked behavioral factors, including stress and medication adherence, to relapse.

Purpose

We sought to determine the effect of participation in a behavioral self-management program on incidence of flare within 12 months following behavioral intervention when compared to the natural history of flare incidence prior to program participation.

Results

Results from a 2-level regression model indicated that those participants in the treatment group were 57% less likely to flare in the following 12 months (compared to 18% in the control group). The decline in “flare odds” was about 2 times greater in treatment versus controls (OR = 0.52, t(34) = 2.07, p < 0.05). Office visits, ER visits, and disease severity (all p < 0.05) were identified as moderators of flare risk.

Conclusions

We have demonstrated 1) a statistical model estimating the likelihood of flare rates in the 12 months following a behavioral intervention for IBD (compared to a control condition), and 2) that the introduction of a behavioral intervention can alter the natural course of a chronic, relapsing and remitting gastrointestinal condition such as IBD.     

Duality and nonduality in meditation research

The great variety of meditation techniques found in different contemplative traditions presents a challenge when attempting to create taxonomies based on the constructs of contemporary cognitive sciences. In the current issue of Consciousness and Cognition, Travis and Shear add ‘automatic self-transcending’ to the previously proposed categories of ‘focused attention’ and ‘open monitoring’, and suggest characteristic EEG bands as the defining criteria for each of the three categories. Accuracy of current taxonomies and potential limitations of EEG measurements as classifying criteria are discussed.     

Religion, Social Capital, and Health

Religion??s association with better physical health has been partially explained by health behaviors, psychosocial variables, and biological factors; but these factors do not fully explain the religion?Chealth connection. In concert with the religion and health literature, a burgeoning literature has linked social capital with salubrious health outcomes. Religious organizations are recognized in the social capital literature as producers and facilitators of social capital. However, few studies have examined the potential mediating role of social capital in the religion?Chealth relationship. Thus data from the 2006 Social Capital Community Benchmark Survey were analyzed for 10,828 adults. The composite unstandardized indirect effect from religion to social capital onto health was significant (???=?0.098; p?<?0.001). The unstandardized direct pathway from religion to self-reported health (???=?0.015; p?=?0.336) indicated that social capital is a mediator in the religion?Chealth relationship. Among the demographic variables investigated, only age and income had a significant direct effect on self-reported health.     

Exploring the Relationship Between Conduct Disorder and Residential Treatment Outcomes

We examined the differential outcomes in residential treatment for youths with conduct disorder (CD)—with special attention paid to interactions with age and gender—in a sample of children and adolescents in 50 residential treatment centers and group homes across Illinois. Multi-disciplinary teams rated youths ages 6–20 (N = 457) on measures of mental health and other factors within 30 days of admission, about 7 months after admission, and at discharge. While both groups initially responded similarly to treatment, the CD group performed better relative to the non-CD group over the full course of treatment, showing healthier relative change on five outcomes variables and more significant improvement. Age range moderated the relationship between CD group membership and change in work/school performance. There were significant between groups differences within the youngest age group (6–11 years) in which the CD group worsened relative to the non-CD group.     

Outcome Trajectories for Adolescents in Residential Treatment: A Statewide Evaluation

Although residential treatment represents one of the largest and most expensive components of the mental health service system for children and adolescents, little is known about the anticipated outcomes of this service. Still less is known about the trajectory through which change occurs within these settings. We examined the clinical status of 285 adolescents over a 2-year period after placement in residential treatment by the Department of Mental Health in a western state. Using a growth modeling technique, the rate of change was determined over a set of symptoms measured by the Acuity of Psychiatric Illness—Child and Adolescent Version (CAPI). Results suggest that while adolescents tended to improve overall during the course of their stays, there was considerable variation in which symptoms improved and which did not. Two symptoms actually became reliably worse with treatment. In addition, significant variation in outcomes was demonstrated across sites, with adolescents in one site getting reliably worse during the course of residential treatment. Our findings demonstrate the utility of outcomes management and have significant implications for how residential services for children and adolescents should be managed.     

Home-based intervention for infants with developmental disorders

A hom-based therapeutic program for infants with developmental disorders is described. The program is used at the Institute for Psychophysiological and Speech Disorders, Belgrade, Yugoslavia. Significant changes in infant developmental competence provide support for the use of parents as direct intervention agents for their infants. Positive changes in marital and family relationships are important side effects of parent involvement in the therapeutic habilitation of their children.
