An Attributional Analysis of Aggression Among Children who are Deaf

This exploratory study applied attribution theory to explain aggressive behaviors using a sample of thirty children who are deaf, ages 9-12. Students were shown four hypothetical scenarios of a child causing another child minor harm, such as bumping into him or her in the hall. The intention of the provocateur was ambiguous. Participants were instructed to pretend they were the child who had been harmed. Subsequently, they were questioned about the provocateur\u27s intentions, their own emotional responses, and their likely behavioral response. Consistent with our predictions, many children demonstrated hostile (i.e., hostile) attributional biases. Moreover, the results support the cognition, emotion, behavior sequence posited by attribution theory: the more intent participants ascribed to the provocateur, the angrier they reported being, and the more likely they were to anticipate responding aggressively. The relation between hostile attributions and aggressive responding was mediated by emotion. The findings underscore some potential cognitive and emotional antecedents of behavioral problems in a deaf population

Variable sizes of Escherichia coli chemoreceptor signaling teams

Like many sensory receptors, bacterial chemotaxis receptors form clusters. In bacteria, large-scale clusters are subdivided into signaling teams that act as ‘antennas' allowing detection of ligands with remarkable sensitivity. The range of sensitivity is greatly extended by adaptation of receptors to changes in concentrations through covalent modification. However, surprisingly little is known about the sizes of receptor signaling teams. Here, we combine measurements of the signaling response, obtained from in vivo fluorescence resonance energy transfer, with the statistical method of principal component analysis, to quantify the size of signaling teams within the framework of the previously successful Monod–Wyman–Changeux model. We find that size of signaling teams increases 2- to 3-fold with receptor modification, indicating an additional, previously unrecognized level of adaptation of the chemotaxis network. This variation of signaling-team size shows that receptor cooperativity is dynamic and likely optimized for sensing noisy ligand concentrations
