Egograms and the “Constancy Hypothesis” - Aug 26, …

This controversy over whether the alpha-stat or the pH-stat theory is does have practical anaesthetic relevance in patients who are rendered hypothermic (eg while on cardiopulmonary bypass). What is the pH level to aim for in these patients? It seems that the alpha-stat theory is now widely accepted. This is probably related to the intellectual attraction of the theoretical arguments because major differences in outcome between groups of patients managed by the pH-stat or the alpha-stat technique have not been clear. Cells are capable of functioning despite the presence of perturbation. Clinical studies have concentrated on which approach is best for the heart (myocardial outcome) and/or which approach is best for the brain (neurological outcome). a pCO2 level. cerebral blood flow

Discussion: Sensations and the Constancy Hypothesis | …

Dusay, J. (1972). Egograms and the “constancy hypothesis.” Transactional Analysis Journal, 2(3), 37-41.

When foraging for nectar many insects exhibit flower constancy (a preference for flower species which they have previously visited) and frequently ignore rewarding flowers of other species. Darwin proposed the favoured explanation for this behaviour, hypothesizing that learning of handling skills for one flower species interferes with the ability to recall handling skills for previously learned species. A crucial element of this hypothesis is that savings in handling time resulting from constancy must exceed increases in travelling time necessitated by ignoring other suitable species. A convincing quantification of this trade-off has not been achieved and tests to date on bumblebees indicate that savings in handling time are too small to offset an increase in travelling time. To assess further the validity of Darwin's hypothesis, handling and flight times of the butterfly, Thymelicus flavus, were measured under natural conditions, and the abundance and reward provided by the available flower species quantified to enable estimation of foraging efficiency. Butterflies exhibited a mean increase in handling time of 0.85 s per flower associated with switching between flower species, although the magnitude of this difference varied greatly among flower species. Switching was not associated with a decrease in travelling time, contrary to expectation. Switching was more frequent following a lower than average reward from the last flower visited. In butterflies, flights serve functions other than movement between nectar sources, such as mate location (unlike worker bees). Hence constancy may be a viable strategy to reduce time spent in handling flowers and increase time available for other activities. Although savings in handling time may be small, Darwin's interference hypothesis remains a valid explanation for flower constancy in foraging butterflies.

The alphastat hypothesis is about maintaining alpha which means that the net charge on all proteins is kept constant despite changes in temperature. This ensures that all proteins can function optimally despite temperature changes. The importance of pH is not just about intracellular trapping of metabolic intermediates (small molecule effect) but also about protein function (large molecule effect). This affects all proteins, though enzymes usually figure prominently as examples. So, to answer the question about why pH is so important in metabolism involves these two reasons.

Bartlett's test is another test that can be used to test for constant variance. The objective is to again perform the following hypothesis test:

Methods are the actual interventions that are used in psychotherapy practice. They are reproducible; that is, a therapist can model a specific intervention and another therapist can learn to create a somewhat similar intervention. A theory of method provides an understanding of how methods may be designed. It provides an orientation to the practice of psychotherapy, a therapeutic stance: supportive, analytic, relational, or replacement (Trautmann, 1981). One such methodological orientation is the premise that healing occurs through the use of a therapeutic relationship that focuses on enhancing internal and external contact. This provides both an overall framework from which specific methods are designed and a conceptual beacon that serves as a guide to the therapist in the continual monitoring of observations, theories, hypotheses, and specific interventions (Erskine, 1982).

The imidazole has a degree of dissociation (referred to as alpha) of 0.55 in the intracellular compartment and this remains constant despite changes in temperature (ie the pK is changing with change in temperature). This theory about the constancy of the imidazole alpha value as proposed by Reeves and Rahn has been termed the imidazole alphastat hypothesis.

As with the normality tests considered in the previous section, we hope we fail to reject the null hypothesis as this would mean the variance is constant. The test statistic for the above is computed as follows:
