Physical Maltreatment Victim to Antisocial Child: Evidence of an Environmentally Mediated Process.

The well-documented finding that child physical maltreatment predicts later antisocial behavior has at least 2 explanations: (a) Physical maltreatment causes antisocial behavior, and (b) genetic factors transmitted from parents to children influence the likelihood that parents will be abusive and that children will engage in antisocial behavior. The authors tested these hypotheses in the representative Environmental-Risk cohort of 1,116 twin pairs and their families, who were assessed when the twins were 5 and 7 years old. Mothers reported on children's experience of physical maltreatment, and mothers and teachers reported on children's antisocial behavior. The findings support the hypothesis that physical maltreatment plays a causal role in the development of children's antisocial behavior and that preventing maltreatment can prevent its violent sequelae.

Discriminative Stimulus, Reinforcing, Physical Dependence, and Antinociceptive Effects of Oxycodone in Mice, Rats, and Rhesus Monkeys.

Despite oxycodone's (4,5-epoxy-14-hydroxy-3-methoxy-17-methylmorphinan-6-one) history of clinical use and the attention it has received as a drug of abuse, few reports have documented its pharmacology's relevance to its abuse or its mechanism of action. The purposes of the present study were to further characterize the analgesic effects of oxycodone, its mechanism of action, and its effects in terms of its relevance to its abuse liability. The results indicate that oxycodone had potent antinociceptive effects in the mouse paraphenylquinone writhing, hot-plate, and tail-flick assays, in which it appeared to be acting as a μ-opioid receptor agonist. It generalized to the heroin discriminative stimulus and served as a positive reinforcer in rats and completely suppressed withdrawal signs in morphinedependent rhesus monkeys. These results suggest that the analgesic and abuse liability effects of oxycodone are likely mediated through μ-opioid receptors and provide the first laboratory report of its discriminative stimulus, reinforcing, and morphine cross-dependency effects.

Romantic versus realistic views of psychology.

Comments on the article by R. J. Sternberg and E. L. Grigorenko (see record 2001-10045-001), which described an approach to psychology ("unified psychology") that is a multiparadigmatic, multidisciplinary, and integrated study of psychological phenomena through converging operations. According to the present author, Sternberg and Grigorenko ignored fundamental methodological differences within the discipline when they developed their concept of unified psychology. In addition, Sternberg and Grigorenko's conception of a unified psychology was achieved by extending the meanings of converging operations (W. R. Garner et al, 1956) and paradigm (T. S. Kuhn, 1970) beyond their original intent. Sternberg and Grigorenko flagrantly ignored striking differences among contemporary psychologists' criteria for truth or verisimilitude. Instead of viewing psychology within the context of converging operations and paradigms and holding the amorphous conception that psychologists "need adhere to no particular set of methods, to no particular field, and to no particular paradigm," psychologists should consider an alternative, more direct approach: explicitly stating both the nature of the psychological phenomena to be studied and as well as their intended mode of explanation.

Foreword: Values in psychotherapy.

Contends that the glory of psychotherapists' "tree of psychology" is that its roots are absolutely philosophical and, therefore, limitless in scope and devoid of absolute proofs. The trunk of this tree is a solid and substantial store of scientific and empirical data. The branches bear a multitude of flowers, many of which are not quite substantial; not made to endure the critical climate of a questioning world. Ultimately, however, these flowers contain the germinating factor, that which allows human knowledge the possibility of continued growth and rejuvenation.
