Caregiving behavior and interactions of prenatally depressed mothers (antidepressant‐treated and non‐antidepressant‐treated) during newborn acute pain

This exploratory study aimed to examine time‐based measures of the behaviors and interactions of prenatally depressed serotonin reuptake inhibitors (SRI)‐medicated mothers to their infant's pain (n = 10) by comparing them with similar measures obtained from prenatally depressed nonmedicated mothers and their infants (n = 10), and nondepressed mothers and their infants (n = 10). During the second trimester of their pregnancy, the 30 study mothers were assessed for depression and anxiety, with no further measures of maternal mood taken. Maternal and infant interactions were continuously videorecorded while the infant underwent a scheduled heel lance for routine blood screening that occurred when study infants were between the ages of 24 and 60 hr. Maternal behavior and infant cry, for all 30 cases, were coded second‐by‐second for the full duration of each infant's heel lance using a reliable coding system and analyzed using odds ratio and regression analyses. Infants exposed to prenatal SRIs and depressed maternal mood were more likely to have lower Apgar scores and to exhibit weak and absent cry. Even when duration of the heel lance was controlled for, women with depression during the second trimester were more likely to exhibit depressed behavior at 2 days' postpartum despite sustained SRI antidepressant treatment. Both groups of prenatally depressed mothers were more likely to exhibit diminished response to their infants' pain cue although nonmedicated mothers' expressions of depressed behavior were more similar to healthy controls. Comprehensive understanding is essential to optimize the clinical care of mothers and their infants in this complex setting. This study contributes preliminary new findings that warrant prospective and longitudinal studies to clarify further the impacts of prenatal SRI and maternal mental mood (e.g., chronic depression and anxiety) effects on the mother–infant interaction and infant pain and stress reactivity.     

Expert image analysts show enhanced visual processing in change detection

Expertise facilitates change detection performance, but the neural underpinnings of these benefits are unknown. Expert image analysts showed larger change-related ERP effects between about 100–200 msec after stimulus onset than did novices, which correlated with both accuracy and years of analysis experience. These results demonstrate that years of visual experience can induce fundamental changes in early visual processing which are related to change detection abilities.     

Broaching the Subjects of Race,Ethnicity, and Culture During the Counseling Process

The authors define broaching as the counselor's ability to consider how sociopolitical factors such as race influence the client's counseling concerns. The counselor must learn to recognize the cultural meaning clients attach to phenomena and to subsequently translate that cultural knowledge into meaningful practice that facilitates client empowerment, strengthens the therapeutic alliance, and enhances counseling outcomes. A continuum of broaching behavior is described, and parallels are drawn between the progression of broaching behavior and the counselor's level of racial identity functioning.     

Altered emotional decision-making in prisoners with borderline personality disorder

Previous studies have identified neuropsychological deficits in individuals with antisocial personality disorder and/or psychopathy. Few studies have examined neuropsychological functioning in individuals with borderline personality disorder (BPD), and no studies have yet investigated cognitive and emotional function in male prisoners with BPD. In this study, we compared the risky decision-making of 17 participants with a history of serious violent or sexual offenses and a diagnosis of DSM-IV BPD with that of 17 participants with similar offending histories but personality disorders other than BPD. Those with BPD exhibited altered processing of information about potential losses (punishment) when the probability of gains (reward) was high; they also increased their choice of risky options even in circumstances where this was clearly avoidable. These data suggest that individuals with a diagnosis of BPD and a history of serious offenses have problems integrating different reinforcement signals when choosing between risky actions, perhaps reflecting corticolimbic dysfunction as an underlying mechanism in BPD.     

What is the function of nail biting: an analog assessment study

OBJECTIVE: To compare the frequency of nail biting in 4 settings (interventions) designed to elicit the functions of nail biting and to compare the results with a self-report questionnaire about the functions of nail biting. DESIGN: Randomised allocation of participants to order of conditions. SETTING: University Psychology Department. SUBJECTS: Forty undergraduates who reported biting their nails. INTERVENTIONS: Left alone (boredom), solving maths problems (frustration), reprimanded for nail biting (contingent attention), continuous conversation (noncontingent attention). MAIN OUTCOME MEASURES: Number of times the undergraduates bit their nails. RESULTS: Nail biting occurred most often in two conditions, boredom and frustration. CONCLUSION: Nail biting in young adults occurs as a result of boredom or working on difficult problems, which may reflect a particular emotional state. It occurs least often when people are engaged in social interaction or when they are reprimanded for the behavior.     

Parent and Child Agreement for Acute Stress Disorder,Post-Traumatic Stress Disorder and other Psychopathology in a Prospective Study of Children and Adolescents Exposed to Single-Event Trauma

Examining parent-child agreement for Acute Stress Disorder (ASD) and Post-Traumatic Stress Disorder (PTSD) in children and adolescents is essential for informing the assessment of trauma-exposed children, yet no studies have examined this relationship using appropriate statistical techniques. Parent-child agreement for these disorders was examined by structured interview in a prospective study of assault and motor vehicle accident (MVA) child survivors, assessed at 2–4 weeks and 6 months post-trauma. Children were significantly more likely to meet criteria for ASD, as well as other ASD and PTSD symptom clusters, based on their own report than on their parent’s report. Parent-child agreement for ASD was poor (Cohen’s κ = −.04), but fair for PTSD (Cohen’s κ = .21). Agreement ranged widely for other emotional disorders (Cohen’s κ = −.07–.64), with generalised anxiety disorder found to have superior parent-child agreement (when assessed by phi coefficients) relative to ASD and PTSD. The findings support the need to directly interview children and adolescents, particularly for the early screening of posttraumatic stress, and suggest that other anxiety disorders may have a clearer presentation post-trauma.     

Group-directed criticisms and recommendations for change: why newcomers arouse more resistance than old-timers

Three experiments examine the extent to which newcomers are able to influence their groups relative to old-timers. Specifically, how group members respond to criticisms of their group was assessed as a function of the intragroup position of the speaker. When criticizing their workplace (Experiment 1; N = 116), their profession (Experiment 2; N = 106), or an Internet community (Experiment 3; N = 189), newcomers aroused more resistance than old-timers, an effect that was mediated by perceptions of how attached critics were to their group identity. Experiment 3 also showed that newcomers could reduce resistance to their criticisms by distancing themselves from a group of which they were previously members. Theoretical and practical implications of these findings are discussed.     

Functional MRI of Language in Aphasia: A Review of the Literature and the Methodological Challenges

Animal analogue studies show that damaged adult brains reorganize to accommodate compromised functions. In the human arena, functional magnetic resonance imaging (fMRI) and other functional neuroimaging techniques have been used to study reorganization of language substrates in aphasia. The resulting controversy regarding whether the right or the left hemisphere supports language recovery and treatment progress must be reframed. A more appropriate question is when left-hemisphere mechanisms and when right-hemisphere mechanisms support recovery of language functions. Small lesions generally lead to good recoveries supported by left-hemisphere mechanisms. However, when too much language eloquent cortex is damaged, right-hemisphere structures may provide the better substrate for recovery of language. Some studies suggest that recovery is particularly supported by homologues of damaged left-hemisphere structures. Evidence also suggests that under some circumstances, activity in both the left and right hemispheres can interfere with recovery of function. Further research will be needed to address these issues. However, daunting methodological problems must be managed to maximize the yield of future fMRI research in aphasia, especially in the area of language production. In this review, we cover six challenges for imaging language functions in aphasia with fMRI, with an emphasis on language production: (1) selection of a baseline task, (2) structure of language production trials, (3) mitigation of motion-related artifacts, (4) the use of stimulus onset versus response onset in fMRI analyses, (5) use of trials with correct responses and errors in analyses, and (6) reliability and stability of fMRI images across sessions. However, this list of methodological challenges is not exhaustive. Once methodology is advanced, knowledge from conceptually driven fMRI studies can be used to develop theoretically driven, mechanism-based treatments that will result in more effective therapy and to identify the best patient candidates for specific treatments. While the promise of fMRI in the study of aphasia is great, there is much work to be done before this technique will be a useful clinical tool.     

"Despair" induced by extinction trials in the water maze: relationship with measures of anxiety in aged and adult rats

We have previously reported that extinction of escape behavior in the water maze due to the removal of the platform coincided with the development of behavioral "despair" in aged and adult rats, as assessed by immobility. The present study examines further predictions derived from the hypothesis that the withholding of reinforcement induces behaviors akin to depression. We tested for correlations between extinction performance and immobility, as well as between immobility and measures of anxiety in aged and adult rats. Age comparisons were also performed on these variables. Forty aged and 29 adult male Wistar rats (24 and 3 months old, respectively) were examined in the open field, black/white box and elevated-plus maze followed by 6 days of training in the water maze hidden platform task and 8 days of extinction without the platform. Indices of immobility increased over trials of extinction, with the aged showing higher levels, earlier onsets and larger slope increases of immobility than the adults. A lower resistance-to-extinction was predictive of more "despair" in both age groups. Between-group differences in the open field, black/white box and elevated-plus maze indicated that the aged showed more anxiety-like behavior than the adults and/or explored these environments less. Within the aged group, indicators of fearfulness in the three tests were predictive of higher levels of "despair". The extinction-despair model is held to provide the promise of a conceptual and empirical model of human depression that is the consequence of withdrawal of reinforcement.
