Mental Health and Dangerousness: Characteristics and Outcomes of Children and Adolescents in Residential Placements

Violence has been identified as a significant risk behavior among children and adolescents. Dangerousness is a factor in psychiatric hospitalizations and out-of-community placements. However, there is only a small amount of research that has investigated the mental health co-morbidities and treatment outcomes of violent children and adolescents. A random sample of children and adolescents in residential placements through the State of Florida's child welfare system were studied. Cases were classified into three levels of dangerousness. Results indicated that dangerousness was associated with much elevated mental health co-morbidity. Also, cases who were dangerous at the time of admission had less developed peer and moral/spiritual strengths than did other cases. Although dangerous cases had worse dispositional outcomes, there was strong evidence that these cases derived the most clinical benefit from residential treatment.     

Influence of endogenous and exogenous orientations of attention on inhibition of return in a cross-modal target-target aiming task

The authors conducted 2 experiments in which participants (N = 16 in each) executed successive unimanual aiming movements to target locations that were indicated by the onset of either an auditory or a visual stimulus. In Experiment 1 (exogenous orientation), inhibition of return (IOR) effects were observed, with reliable reaction time (RT) costs associated with movements returning to the same target and a trend toward larger IOR effects in left than in right space. There was no influence of stimulus modality on the magnitude of IOR. IOR was also observed in Experiment 2 (endogenous orientation), except the influence of stimulus modality reliably mediated those effect. In that case, IOR was evident only when the previous modality was visual and the current modality was auditory. Together, the results of those 2 experiments suggest that in situations in which 2 paired movements constitute the response criteria, IOR is both supramodal and lateralized to contralateral space.     

Nicotine and familial vulnerability to schizophrenia: a discordant twin study

Tobacco use is significantly associated with schizophrenia. However, it is not clear if smoking is associated with the illness itself, treatment, or underlying vulnerability to the disease. Smoking was studied in a sample of schizophrenic probands (n = 24), their unaffected co-twins (n = 24), and controls (n = 3,347). Unaffected co-twins had higher rates of daily smoking than controls. Probands and co-twins were more frequently unsuccessful in attempts to quit than controls. Probands reported shaky hands and depression following smoking cessation more often than controls, whereas unaffected co-twins reported difficulty concentrating, drowsiness, nervousness, and headache following smoking cessation more often than controls. Results are consistent with the hypothesis that nicotine use is influenced by familial vulnerability to schizophrenia, not just clinical schizophrenia per se.     

A twin study of the association between pathological gambling and antisocial personality disorder

Many individuals with a history of pathological gambling (PG) also have a history of engaging in antisocial behaviors, and this has often been interpreted as a result of the former causing the latter. In a sample of 7,869 men in 4,497 twin pairs from the Vietnam Era Twin Registry, the authors examined (a) the association between PG and antisocial personality disorder (ASPD), (b) the extent to which PG might be differentially associated with childhood conduct disorder (CD) and adult antisocial behavior (AAB), and (c) the contribution of genetic and environmental factors to the association of PG with ASPD, CD, and AAB. PG was significantly associated with all 3 antisocial behavior disorders, and the association of PG with ASPD, CD, and AAB was predominantly explained by genetic factors. The results of this study suggest that the greater-than-chance co-occurrence of PG and antisocial behavior disorders is partially due to their sharing a common genetic vulnerability. The antisocial behavior observed among many individuals with PG probably cannot be interpreted as being simply a consequence of the PG.     

Racism,Antisemitism, and the Schism Between Blacks and Jews in the United States: A Pilot Intergroup Encounter Program

A schism now exists between Blacks and Jews in the United States, 2 groups that were strong allies during the civil rights movement. The authors describe the historical antecedents of and contributing factors to this schism and present information on and lessons learned from 2 Black‐Jewish dialogues that were conducted. Existe en la actualidad un cisma entre Negros y Judíos en los Estados Unidos, 2 grupos que fueron grandes aliados durante el movimiento de reivindicación de los derechos civiles. Los autores describen los antecedentes históricos y los factores que han contribuido a este cisma y presentan la información obtenida y las lecciones aprendidas a partir de 2 conversaciones llevadas a cabo entre individuos Negros y Judíos.     

Using temporal cohesion to predict temporal coherence in narrative and expository texts

We investigated the linguistic features of temporal cohesion that distinguish variations in temporal coherence. In an analysis of 150 texts, experts rated temporal coherence on three continuous scale measures designed to capture unique representations of time. Coh-Metrix, a computational tool that assesses textual cohesion, correctly predicted the human ratings with five features of temporal cohesion. The correlations between predicted and actual scores were all statistically significant. In a complementary study, we explored the importance of temporal cohesion in characterizing genre. A discriminant function analysis, using Coh-Metrix temporal indices, successfully distinguished the genres of science, history, and narrative texts. The results suggested that history texts are more similar to narrative texts than to science texts in terms of temporal cohesion.     

Brief functional analysis and supplemental feeding for postmeal rumination in children with developmental disabilities

Rumination is a serious problem demonstrated by some people with developmental disabilities, but previous research has not included a functional analysis and has rarely compared intervention methods during the assessment process. We conducted functional analyses with 2 children who displayed postmeal rumination and subsequently evaluated a supplemental feeding intervention following meals. Results showed that noncontingent food or liquid presentation effectively reduced rumination with both children.
