The effects of alcohol and extreme provocation on the use of a highly noxious electric shock

Intoxicated and nonintoxicated subjects were given the opportunity to administer a potentially injurious level of shock to an opponent who behaved in either a provocative or an extremely provocative manner. The provocative opponent attempted to administer high-intensity shocks to the subject. The extremely provocative opponent attempted to administer high-intensity shocks and the potentially injurious level of shock. The intoxicated subjects in the extreme provocation condition evidenced the greatest increase in the use of the potentially injurious shock. It was concluded that aggression is a function of the interaction of alcohol consumption and level of provocation.     

Serotonin, the superior colliculus, and grooming behavior in cats with neocortical lesions.

Previous studies of cats with pontile lesions indicate that a serotonergic deficit exists in the superior colliculi and that this deficit is involved in the genesis of an abnormal grooming behavior. Cats with frontal neocortical lesions exhibit the same serotonergic deficit and the same abnormal grooming behavior. The present study established that the serotonergic deficit is involved in the mediation of the abnormal grooming behavior in cats with frontal neocortical lesions. Microinjections of 5-hydroxytryptophan (5-HTP) and 5-hydroxytryptamine (5-HT) into the superior colliculi abolished or signigicantly reduced the abnormal behavior in cats with frontal neocortical lesions, whereas no effects of 5-HTP were observed after injections into the cerebrospinal fluid above the superior colliculi, into the tegmentum beneath the superior colliculi, or into the medial dorsal nucleus rostral to the superior colliculi. Other substances (tryptophan, noradrenaline, and gamma-amino-butyric acid) had no effect on the abnormal behavior when injected into the superior colliculi. Further evidence implicating a serotonergic deficit in the mediation of the abnormal behavior was obtained by systemic injections: The abnormal behavior was abolished with 5-HTP in cats with frontal neocortical lesions and in adrenalectomized cats that were previously treated with p-chlorophenylalanine.. The present study also demonstrated that the abnormal grooming behavior is induced by frontal neocortical lesions and not by more caudal lesions of the neocortex. The anatomical relations between the frontal neocortex and the superior colliculus and the role of these structures in grooming behavior are discussed.     

The effect of aversive consequences upon persistent behavior

It was hypothesized that if a behavior is freely engaged in with the expectancy that an aversive consequence will follow, the intrinsic motivation to perform that behavior will increase when the aversive consequence is no longer present. Subjects either worked on a list of anagrams while receiving electric shock on a VR schedule, while being threatened by electric shock, or in the absence of shock. The experimenter then left the subject alone for 10 minutes with a new list of anagrams. Subjects in the shock condition solved more anagrams on the posttest than subjects in the threat-of-shock and noshock conditions. Subjects in both the shock condition and the threat-of-shock condition reported that they spent more of their free time on the anagrams than subjects in the no-shock condition.     

Similarities in the physiological bases of an abnormal grooming behavior in thyroidectomized cats and in cats with lesions of the central nervous system.

Thyroidectomized cats display a dissociation of the appetitive and consummatory components of grooming behavior when the body surface is tactually stimulated, an abnormal behavior that also occurs in cats with pontile or frontal neocortical lesions. Systemic administration of 5-hydroxytryptophan (5-HTP) abolishes the abnormal behavior, whereas dihydroxyphenylalanine administration does not, and p-chlorophenylalanine (PCPA) administration induces the abnormal grooming behavior in thyroidectomized cats that are not displaying the abnormal behavior because of spontaneous seasonal reversions. Microinjections of 5-HTP or serotonin into the superior colliculi also abolish the abnormal grooming behavior in thyroidectomized cats. Lesions of the superior colliculi prevent the development of the abnormal behavior after thyroidectomy, even with PCPA treatment. These pharmacological results in thyroidectomized cats parallel the behavioral effects observed in cats with pontile or frontal neocortical lesions.     

Kotahitanga and koinonia in shalom as the objective of the mission of God

Evangelical theology and the missions that flowed from it was born in an era of high colonialism, shaped by enlightenment dualism and scientific method, under the influence of industrialization. As evangelical Christianity’s centre of gravity shifted south, global North dominance over its theology and missiology persisted, translated into new tongues. This paper, sensing a tipping point in evangelical thought as we emerge out of global pandemic disruption, proposes an alternative framing of church and missions from the collectivist perspective shared by those less affected by the influence of Western industrialization and individualism. It proposes that both the means and the objective of the mission of God should be common unity in-Christ. It shifts focus from the Great Commission to the Great Commitment, which emphasizes being one and holding fast to that unity for the joy that awaits those who persevere in mutuality. Along the way, the demonstration of whole-of-life covenantal community in-Christ serves as our witness to the world, which provides those of us in-Christ with an opportunity to explain the hope that we have and invite others to join us in the experience of God’s shalom goodness.
