Central executive function in mild cognitive impairment: a PET activation study

Using positron emission tomography (PET), we explored the neural correlates of an executive function, dual tasking, in patients with amnestic mild cognitive impairment (aMCI) and in elderly controls. The experiment employed simple auditory and visual tasks that were presented both in isolation and simultaneously to create a task condition requiring enhanced attentional control. Behaviorally, both groups performed well, albeit the patients made more errors on the visual task. The PET analysis focused at prefrontal regions where group differences in task-related activation patterns were expected. During dual task performance, the patients showed attenuated activity in the left inferior frontal region when compared to the controls. This suggests abnormalities in the neural processes underlying attentional control in aMCI.     

PTSD Symptom Clusters Are Differentially Associated with Components of the Acquired Capability for Suicide

Previous research has established the link between posttraumatic stress disorder (PTSD) and suicidal behavior. In the current study, constructs proposed to explain this relationship were examined, applying the framework of the interpersonal‐psychological theory of suicide (IPTS). Relationships between acquired capability for suicide (ACS; i.e., fearlessness about death [FAD] and pain tolerance) and specific PTSD symptom clusters were explored. In a sample of 334 trauma‐exposed undergraduates, anxious arousal and FAD were negatively associated, and numbing and pain tolerance were positively associated. Results establish a foundation for investigating the role of ACS in understanding observed relationships between suicidal behavior and PTSD symptoms.     

Young Adult Follow‐up of Adolescent Girls in Juvenile Justice Using the Columbia Suicide Severity Rating Scale

This study focused on the reliability and validity of the Columbia Suicide Severity Scale (C‐SSRS). Severely delinquent adolescent girls (n = 166) participated in a treatment trial and repeated assessments over time. Lifetime suicide attempt history was measured using the C‐SSRS in early adulthood (n = 144; 7–12 years postbaseline). Nonclinician raters showed strong interrater reliability using the C‐SSRS. Self‐reports, caseworker reports, and caregiver reports of girls' suicide attempt histories collected at baseline correlated with adult participants' recollections of their baseline attempt histories. Suicidal ideation measured prospectively across a 7‐ to –12‐year period was associated with retrospectively reported suicide attempt across the same period.     

The impact of family and peer differentiation levels on adolescent psychosocial development and problematic behaviors

This study examined the impact of family differentiation and peer differentiation levels on adolescent problematic behaviors and psychosocial maturity. Differentiation levels were assessed dyadically in both the family and peer systems. Results revealed family differentiation to be the sole predictor of adolescent problematic behavior. Additional regression analysis indicated that peer differentiation was a significant predictor of psychosocial maturity, along with the significant impact of adolescent gender and age. Family X Peer interaction terms were not significant predictors of either adolescent personal adjustment variable. Results, whichdisplay both consistencies and variations with the findings of previous research, are discussed in terms of their clinical implications.Salary and support provided in part by grants from The Kettering Fund (OSURF #727033) and by The Ohio State University (OSURF #221424 and OSURF #241501).     

Dynamic presentation of magnified graphical characters on the IBM-compatible computers

Software that provides extremely smooth gliding and scrolling of magnified characters and pictograms on standard PCs is described. The program was designed as a tool for reading research, as a computer aid for visually impaired readers, and as a subtitle generator for multimedia applications. Change of font, size of characters, speed, color, and direction of movement can be made interactively. The system is useful for reading remediation and for creation of various visual effects.     

Teacher practices associated with students' sense of the classroom as a community

Data from observations of 232 elementary classrooms and from student questionnaires were used to test a model linking teacher classroom practices to students' sense of the classroom as a community (assessed by questionnaire) through intermediate effects on students' classroom behavior. The model was generally confirmed and showed that teacher practices (emphasis on prosocial values, elicitation of student thinking and expression of ideas, encouragement of cooperation, warmth and supportiveness, andreduced use of extrinsic control) were related to student classroom behaviors (engagement, influence, andpositive behavior), which, in turn, were related to students'sense of community. Teachers' encouragement of cooperative activities appeared to be particularly important in this sequence. The appropriateness of the model was tested for schools serving populations that were both high and low in level of poverty, and all estimates of path coefficients were found to be invariant across these groups.     

Return to Ithaca: A perspective on marriage and love in post traumatic stress disorder

This paper discusses the interactive effects of character development, love in marriage, and the stress pathology in the Vietnam War combatant. Over years of treating Vietnam veterans and their spouses, the authors have observed common patterns of interstructural or intercharacterological meshing between the Vietnam warrior and his wife. Implications for treatment are discussed along with useful intervention strategies.
