DEVELOPMENT AND VALIDATION OF A MEASURE OF EMOTIONAL INTELLIGENCE

This series of studies describes the development of a measure of emotional intelligence based on the model of emotional intelligence developed by Salovey and Mayer [Salovey, P. & Mayer, J. D. (1990). Emotional intelligence. Imagination, Cognition and Personality, 9, 185–211.]. A pool of 62 items represented the different dimensions of the model. A factor analysis of the responses of 346 participants suggested the creation of a 33-item scale. Additional studies showed the 33-item measure to have good internal consistency and testretest reliability. Validation studies showed that scores on the 33-item measure 1. (a) correlated with eight of nine theoretically related constructs, including alexithymia, attention to feelings, clarity of feelings, mood repair, optimism and impulse control; 2. (b) predicted first-year college grades; 3. (c) were significantly higher for therapists than for therapy clients or for prisoners; 4. (d) were significantly higher for females than males, consistent with prior findings in studies of emotional skills; 5. (e) were not related to cognitive ability and 6. (f) were associated with the openness to experience trait of the big five personality dimensions.

Neuropsychological correlates of violence and aggression: A review of the clinical literature

Understanding of factors that influence expression of violence and aggression have become important questions in our society. The present article reviews the role of the neuropsychological factors, including the potential roles of prefrontal brain damage and temporal lobe dysfunction. Mechanisms that allow such damage to influence behavior are discussed, as well as the evidence for such mechanisms. The article examines the influence of these factors in a wide range of populations, including batters, juvenile delinquents, adult criminals, sexual offenders, psychopaths, and schizophrenics. The potential role of additonal factors, such as alcohol, are also briefly examined. Conclusions focus on the influence these findings have in aggression in society and possible treatment issues.

Biological Contributions to the Presentation and Understanding of Attention-Deficit/Hyperactivity Disorder: A Review

Attention-deficit/hyperactivity disorder (ADHD) is the most commonly diagnosed disorder in children today with estimated prevalence rates falling between 3 and 5% of children (American Psychiatric Association, 1994). From inception, research has focused on studying varying facets of this disorder with initial efforts primarily focusing on treatment outcome. However, prominent efforts have been made in recent research efforts to shed light on the etiology of this disorder. Such research has discovered the contribution of genetic inheritance, as well as environmental factors that lead to the development of this disorder. Furthermore, studies using neurological and neuropsychological assessment measures have implicated the involvement of various Parts of the brain. This article critically reviews this body of research in light of its impact on the current specific neuropsychologically based etiological theories, as well as the most beneficial directions for future research.

The relationship of neuropsychological impairment to conduct disorder in adolescence: A conceptual review

This review is an attempt to expand the understanding of the neuropsychological mechanisms that may influence the expression of violent or aggressive behavior in adolescents. Although a relative large literature of adult studies examining the relation of neuropsychological impairment and aggression exists, the research literature investigating this relationship in adolescents is much smaller. With a few exceptions, the delinquent literature suffers from methodological problems, including biased sampling methods, small numbers of subjects, failing to objectively diagnose conduct disorder, incorrect use of specific statistical procedures, and lacking of appropriate control groups. In general, a mixed pattern of neuropsychological deficits are displayed across studies, depending on the sampling method, methodological design, statistics employed, control groups, and assessment tools that were utilized. Verbal deficits have been frequently displayed across the literature, while evidence for executive dysfunction varies, depending on the specific construct being evaluated (e.g., attention, cognitive flexibility, concept formation, planning abilities) and the specific population. Relatively inconsistent findings have been observed for visuospatial, sensory, and motor deficits. This article provides a critical review of this literature and discusses the varying impact that any neurological insult will have, depending on premorbid personality and cognitive functioning, location of the lesion, age at which the injury occurred, childs pre- and postinjury environment, and ability of the brain to adapt to acquired deficits as the result of the insult. On the basis of this review and neuropsychological theory, four subgroups within this population are proposed (i.e., adolescents with subcortical injuries, dominant hemisphere temporal-parietal injuries, nondominant hemisphere temporal-parietal injuries, and injuries to the prefrontal regions), which may better explain the neuropsychological and behavioral outcomes exhibited by this heterogeneous population. Recommendations for future research are offered.

IMPROVEMENT IN CEREBRAL METABOLISM IN CHRONIC BRAIN INJURY AFTER HYPERBARIC OXYGEN THERAPY

While no research study has yet demonstrated convincing evidence for the efficacy of Hyperbaric Oxygen Therapy (HBOT); in patients with chronic neurological disorders (CND), anecdotal studies have been suppor -tive of its use in improving healing of the damaged brain. The current study hypothesized that (1) individuals with CND show increases in cerebral blood flow and metabolism as measured by Single Positron Emission Computed Tomography (SPECT) in the cerebral hemispheres, but not on measures of cerebellar and pons blood flow; and (2) younger patients show more improvement than older patients. The study used archival data to compare 25 older and 25 younger subjects who were given SPECT scans pretherapy, midtherapy, and posttherapy. ANOVAs using the SPECT scans as a within subjects variable and age as a between subjects variable confirmed the hypothesis that the cerebral measures all changed but that the cerebellar and pons measures did not. Post-hoc t-tests confirmed that there was improvement in blood flow from the beginning to the end of the study. An age effect was found on only two of the five measures; however, there were no interactions. Analysis by post-hoc t-tests showed that the younger group had higher blood flows, but not more improvement than the older group. The results provided the first statistical research data to show the effectiveness of HBOT in improving blood flow in CND. These results indicate that HBOT can be an effective part of the treatment for such clients. The implications of these findings and future research directions were discussed.

Ventricular Enlargement in Major Depression

Major depression accompanied by psychosis may be a separate nosological entity from nonpsychotic depression. Investigators have noted behavioral and biochemical differences in psychotic and nonpsychotic patients, as well as differences in response to treatment. A previous study using computed tomography (CT) found enlargement of the lateral cerebral ventricles in patients with manic-depressive illness with psychotic symptoms. The present study examined CT scans of patients with major affective illness that was accompanied by hallucinations, delusions, or both. The ventricles of the depressed group were significantly larger than those of a group of normal controls.

Effect of Alcohol Ingestion on Regional Cerebral Blood Flow

Regional distribution of cerebral blood flow was assessed in 10 normal social drinkers following consumption of .75 g/kg alcohol and in a control session without alcohol. Alcohol increased blood flow in the gray matter in all brain areas except the left anterior area. The results are discussed in terms of the effect of alcohol on regional cerebral activation.

Neuropsychological Deficits Among Patients with Chronic Obstructive Pulmonary Disease

Sixty-six patients with chronic obstructive pulmonary disease (COPD) were evaluated for neuropsychological functioning. While the patients showed normal skills on broad intellectual tasks, they displayed mild cerebral deficits on several neuropsychological tests. Multiple regression analyses revealed that the neuropsychological test battery scores were significantly related to partial pressure of arterial oxygen (PaO2), and to degree of pulmonary impairment. Although the cognitive deficits were real, they were generally small. This result may explain why the widely assumed link between chronic lung disorders and cognitive deficit has been difficult to demonstrate. The general pattern was similar to deficits produced by chronic alcoholism and childhood asthma, with complex skills suffering the greatest insult. Because the cognitive deficits among COPD patients in stable condition are small, it is uncertain whether they have importance clinically or for accomplishing daily activities.

Neuropsychological Consequences of HIV in Children: A Review of Current Literature.

Pediatric HIV has reached epidemic proportions. In 1997, 1.1 million children younger than 15 were living with HIV or AIDS. The virus affects children cognitively and developmentally due to the immaturity of their nervous systems and immune systems. Studies in the area of neuropsychological deficits are as yet limited in number and less well developed than studies on adult HIV. However, despite methodological weaknesses, the literature has proven conclusively that pediatric HIV affects children cognitively, developmentally, emotionally, psychologically, behaviorally, and educationally. Although treatments are allowing these children to live longer, the effects of the virus remain, requiring special care. This review examines the mechanisms behind HIV in children, the neuropsychological findings to date, and the limitations of this work. Possible useful future approaches in understanding the neuropsychological course of the disorder, as well as directions for treatment and prevention are addressed.

Brain Damage Among Mentally Disordered Sex Offenders

The incidence and nature of structural brain dysfunction was investigated in a pilot study sample of individuals currently assigned the Nebraska Penal Code designation of mentally disordered sexual offender. It was hypothesized that the sexual offenders would show a significantly higher incidence of dysfunction than a psychosocially normal group as evidenced by computed tomography scan measures, regional cerebral blood flow, and neuropsychological instruments. The hypothesis was tested by two different methods. One method used a 160 by 160 printout of density numbers generated by computer from computed tomography scans administered to the sexual offenders. The second method used mean blood flow data generated from a Harshaw TASC-5 Regional Cerebral Blood Flow analysis system. Additionally, the Luria-Nebraska Neuropsychological Test Battery was administered as a measure of the behavioral correlates of brain dysfunction. Preliminary analyses indicate that 50% of the sexual offenders tested showed brain dysfunction as demonstrated by decreased density measures, decreased blood flow, and performance deficits on the Luria Battery. The implications of these findings, if confirmed, are substantial on issues of criminal responsibility, sentencing, treatment, and rehabilitation of the sex offender. Case reports of the patients studied are presented.
