Immediate antecedents of caretaker's methods of discipline.

The interactions of children's behaviors and caretakers' disciplinary practices were studied. Mothers of one- to two-year-old children were trained to report parent-child interactions involving negative emotions. Mothers' observations thus provided data on sequences of child behaviors and parental discipline methods in affective encounters. Mothers' most frequent initial responses to children's misbehaviors were verbal prohibitions. Discipline methods less commonly used were explanations, restraint, instruction, physical punishment, and love withdrawal. Mothers made greater use of this range of control methods following children's noncompliance to discipline. Types of discipline were used differentially following noncompliance, depending upon the form of misbehavior. Children's harms against persons were associated with psychological discipline methods, such as reasoning and dramatization of distress. Destruction or property and lapses in self-control in children were associated with parental power assertive techniques, such as physical punishment and love withdrawal. These associations between child behaviors and parental discipline methods illustrate the interactive roles of child and parent in mediating parental attempts to control, teach, and punish their children.

Methylphenidate and cognitive therapy: a comparison of treatment approaches with hyperactive boys.

This study of hyperactive boys evaluated the effects of three modes of treatment in relation to an untreated group. The treatments were administered over a 3-month period and included cognitive training, stimulant drug therapy (methylphenidate), and the two treatments combined. A follow-up assessment was conducted approximately 3 months after contact between the training staff and the child had ceased. Analyses of attentional deployment and cognitive style measures, tests of academic achievement, and behavioral ratings showed that only those children in the two medication treatment conditions demonstrated improvement in attentional deployment and behavioral ratings. In the cognitive therapy condition, there were changes only on measures of attentional deployment. The data did not provide evidence indicating that the combined medication and cognitive therapy condition was any more effective than that condition involving medication alone. Discussion provides future guidelines for evaluation of the relative effectiveness of stimulant drug therapy and other psychological treatment modalities.

Pseudoseizure "status".

Psychogenic pain, disturbances of gait and stance, sensory symptoms, dizziness, and psychogenic seizures have been found to be the most common conversion symptoms in neurology clinics. A retrospective analysis of 18 patients suffering from pseudoseizure "status" is presented in this study. All of the patients fulfilled the DSM-III-R criteria of conversion disorder. However, 5 of them had concomitant major depression, 6 suffered from bulimia nervosa, and 7 met the criteria for substance abuse. On Axis II, 10 cases of borderline personality disorder, 2 cases of antisocial personality disorder, and 3 cases of histrionic personality disorder were diagnosed. The majority of the patients had attempted suicide and other forms of self-destructive behavior. The findings suggest that patients with pseudoseizure "status" suffer from severe affective imbalances and disturbed impulse control.

Reward deficiency syndrome: genetic aspects of behavioral disorders.

The dopaminergic and opioidergic reward pathways of the brain are critical for survival since they provide the pleasure drives for eating, love and reproduction; these are called 'natural rewards' and involve the release of dopamine in the nucleus accumbens and frontal lobes. However, the same release of dopamine and production of sensations of pleasure can be produced by 'unnatural rewards' such as alcohol, cocaine, methamphetamine, heroin, nicotine, marijuana, and other drugs, and by compulsive activities such as gambling, eating, and sex, and by risk taking behaviors. Since only a minority of individuals become addicted to these compounds or behaviors, it is reasonable to ask what factors distinguish those who do become addicted from those who do not. It has usually been assumed that these behaviors are entirely voluntary and that environmental factors play the major role; however, since all of these behaviors have a significant genetic component, the presence of one or more variant genes presumably act as risk factors for these behaviors. Since the primary neurotransmitter of the reward pathway is dopamine, genes for dopamine synthesis, degradation, receptors, and transporters are reasonable candidates. However, serotonin, norepinephrine, GABA, opioid, and cannabinoid neurons all modify dopamine metabolism and dopamine neurons. We have proposed that defects in various combinations of the genes for these neurotransmitters result in a Reward Deficiency Syndrome (RDS) and that such individuals are at risk for abuse of the unnatural rewards. Because of its importance, the gene for the [figure: see text] dopamine D2 receptor was a major candidate gene. Studies in the past decade have shown that in various subject groups the Taq I A1 allele of the DRD2 gene is associated with alcoholism, drug abuse, smoking, obesity, compulsive gambling, and several personality traits. A range of other dopamine, opioid, cannabinoid, norepinephrine, and related genes have since been added to the list. Like other behavioral disorders, these are polygenically inherited and each gene accounts for only a small per cent of the variance. Techniques such as the Multivariate Analysis of Associations, which simultaneously examine the contribution of multiple genes, hold promise for understanding the genetic make up of polygenic disorders.

Evidence for a relationship between cage stereotypies and behavioural disinhibition in laboratory rodents.

Cage stereotypies-abnormal, repetitive, unvarying and apparently functionless behaviours-are common in many captive animals, sometimes resulting in self-injury or decreased reproductive success. However, a general mechanistic or neurophysiological understanding of cage stereotypies has proved elusive. In contrast, stereotypies in human mental disorder, or those induced by drugs or brain lesions, are well understood, and are thought to result from the disinhibition of behavioural selection by the basal ganglia. In this study, we found that the cage stereotypies of captive bank voles also correlate with signs of altered response selection by the basal ganglia. Stereotypic bar-mouthing in the caged voles correlated with inappropriate responding in extinction learning, impairments of response timing, evidence of a knowledge-action dissociation, increased rates of behavioural activation, and hyperactivity. Furthermore, all these signs intercorrelated, implicating a single underlying deficit consistent with striatal disinhibition of response selection. Bar-mouthing thus appears fundamentally similar to the stereotypies of autists, schizophrenics, and subjects treated with amphetamine or basal ganglial lesions. These results represent the first evidence for a neural substrate of cage stereotypy. They also suggest that stereotypic animals may experience novel forms of psychological distress, and that stereotypy might well represent a potential confound in many behavioural experiments.

Is a mild deficit in executive functions in boys related to childhood ADHD or to parental multigenerational alcoholism?

A mild deficit in executive functions has been hypothesized to be associated with attention deficit hyperactivity disorder (ADHD), with externalizing problem behaviors such as conduct disorder (CD) and with the vulnerability to alcoholism in sons of multi-generational alcoholics (SOMGAs). These three categories overlap, which raises concerns about the specificity of the hypothesized associations. In the present study, measures of executive functions (EFs) were tested in seventy-six 7- to 11-year-old boys: boys with ADHD but without a family history of addiction, SOMGAs, and controls. Specific deficits in EFs were found for boys with ADHD but not for SOMGAs. The association between a deficit in EFs and attention problems remained after controlling for externalizing problem behaviors, but not for the reverse. These results suggest that a mild deficit in EFs is specifically related to ADHD and that the deficits reported in boys with CD and in SOMGAs are due to relatively high attentional problems in these groups or due to other factors such as motivation.

Selective serotonin reuptake inhibitor treatment of post-traumatic Klüver-Bucy syndrome.

Two cases of Klüver-Bucy syndrome following severe traumatic brain injury (TBI), are described during the period of recovery from acute TBI. These patients posed significant management problems, until successfully managed with selective serotonin reuptake inhibitors (SSRIs). These cases support the benefit of SSRIs in treating associated Klüver-Bucy syndrome.

Prediction of elementary school children's externalizing problem behaviors from attentional and behavioral regulation and negative emotionality.

The purpose of this study was to examine the moderating role of individual differences in negative emotionality in the relations of behavioral and attentional (emotional) regulation to externalizing problem behaviors. Teachers' and one parent's reports of children's regulation (attentional and behavioral), emotionality, and problem behavior were obtained when children were in kindergarten to grade 3 and two years later (N = 169; 146 in major analyses); children's behavioral regulation also was assessed with a measure of persistence. According to the best fitting structural equation model, at two ages behavioral dysregulation predicted externalizing behavior problems for children both high and low in negative emotionality, whereas prediction of problem behavior from attentional control was significant only for children prone to negative emotionality. There were unique, additive effects of behavioral and attentional regulation for predicting problem behavior as well as moderating effects of negative emotionality for attentional regulation.

Whom to refer for group psychotherapy.

The authors believe that group psychotherapy is a useful modality in terms of both economic use of resources and manpower and effective treatment for many common problems. Three major indications for group therapy are inappropriate patterns of interpersonal relationships, the tendency to act immediately on feelings, and the potential or existence of a transference that impedes individual therapy. Patients in these categories who are also in crisis or have a neurotic problem for which the development of a transference neurosis is indicated may require individual therapy instead of or in addition to group therapy. The attitude of the referring physician is crucial; he/she must provide support during the transition and must believe that group therapy can substantially benefit the patient.
