The relation of prosocial behavior to the development of aggression and psychopathology.

The development of prosocial behavior is traced from middle childhood to adulthood in a 22-year longitudinal study of 800 children first seen at age 8 and is compared to the development of aggression over the same period. Prosocial behavior and aggression seem to represent opposite ends of a single dimension of behavior since they are consistently negatively related to each other and relate in opposite ways to correlated variables both synchronously and over time. Both are stable forms of behavior with good predictability over the time span studied and both are related to the quality of the parent-child relationship. The most important deterrent to the development of antisocial behavior and the encouragement of prosocial behavior is probably a close identification between the child and hidher parents.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/83382/1/1984.Eron&Huesmann.RelatofProsocBehavtotheDevelofAggn&Psychopath.AggBehav.pd

Probe similarity and recognition of set membership: A parallel processing serial feature matching model

A model for memory scanning is proposed in which the encoded representation of a probe is compared in parallel with encoded representations of each item in the positive set. The within item matches are serial feature by feature comparisons that terminate when either a positive or negative criterion is reached. This model is shown to predict the results of a probe similarity experiment. The serial location of a similarity within an item affects negative reaction times, but the number of items in the positive set to which the probe is similar has no main effect. The model is also shown to yield predictions consonant with existing data on the relation between reaction times and set size and speed-accuracy trade offs.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/83371/1/1976.Huesmann&Woocher.ProbeSimilarity&Recognition.CognitPsych.pd

A relaxationless demonstration of the Quantum Zeno Paradox on an individual atom

The driven evolution of the spin of an individual atomic ion on the ground-state hyperfine resonance is impeded by the observation of the ion in one of the pertaining eigenstates. Detection of resonantly scattered light identifies the ion in its upper ``bright'' state. The lower ``dark'' ion state is free of relaxation and correlated with the detector by a null signal. Null events represent the straightforward demonstration of the quantum Zeno paradox. Also, high probability of survival was demonstrated when the ion, driven by a fractionated $\pi$ pulse, was probed {\em and monitored} during the intermissions of the drive, such that the ion's evolution is completely documented.Comment: 7 page

Influence of Additives in Metalworking Fluids on the Wear Resistance of Steels

AbstractTheability of metalworking fluids (MWF) to cool and lubricate the contact zone between tool and workpiece is strongly dependent on the surface-active substances such as extreme pressure additives (EP) and passive extreme pressure additive (PEP) as well as the chemical surface properties of steel.Low alloyed steels and stainless steels were examined with a wear resistance test by applying MWF with defined varied concentrations of additivesfeaturing different properties e.g. regarding activity and molecular structure.The wear resistance was assessed and correlated with the chemical properties of the metals. Synergistic and antagonistic effects were obtained and will be discussed. The results gained from the experiments, clearly indicate, why the amount of the additives is less decisive for wear resistance than the relative ratio of polar and unpolar EP/PEP-additives.The optimal result furthermore depends on the chemical properties of the considered surfaces

Intellectual functioning and aggression

In a 22-year study, data were collected on aggressiveness and intellectual functioning in more than 600 subjects, their parents, and their children. Both aggression and intellectual functioning are reasonably stable in a subject's lifetime and perpetuate themselves across generations and within marriage pairs. Aggression in childhood was shown to interfere with the development of intellectual functioning and to be predictive of poorer intellectual achievement as an adult. Early 1Q was related to early subject aggression but did not predict changes in aggression after age 8. On the other hand, differences between early IQ and intellectual achievement in middle adulthood were predictable from early aggressive behavior. A dual-process model was offered to explain the relation between intellectual functioning and aggressive behavior. We hypothesized that low intelligence makes the learning of aggressive responses more likely at an early age, and this aggressive behavior makes continued intellectual development more difficult.The research described here was supported by Grant MH-34410 to Leonard D.

Mitigating the imitation of aggressive behaviors by changing children's attitudes about media violence.

A sample of 169 first- and third-grade children, selected because of their high exposure to television violence, was randomly divided into an experimental and a control group. Over the course of 2 years, the experimental subjects were exposed to two treatments designed to reduce the likelihood of their imitating the aggressive behaviors they observed on TV. The control group received comparable neutral treatments. By the end of the second year, the experimental subjects were rated as significantly less aggressive by their peers, and the relation between violence viewing and aggressiveness was diminished in the experimental group.This research was supported in part by grants MH-28280 and MH-31886 from the National Institute of Mental Health.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/83377/1/1983.Huesmann_etal.MitigatingtheImitatofAggressBehavbyChangingChildren's.JourofPersonality&SocialPsych.pd
