Antenatal caregiving representations and perinatal behavior in mothers with severe lifetime psychopathology

Psychopathology poses a risk for optimal parenting. The current study explored antenatal caregiving representations as markers for later risk of nonoptimal maternal behavior among mothers with severe mental illness. Sixty-five mothers diagnosed with psychosis, bipolar disorder, depression (psychopathology group), and nonclinical controls participated in a longitudinal study from pregnancy to 16 weeks after birth. Mental health diagnoses and caregiving representations were assessed during pregnancy. Maternal behavior was assessed during the 5-min recovery phase of the still-face paradigm at 16 weeks. Mothers with psychopathology reported significantly higher levels of “heightened” caregiving representations (i.e., separation anxiety from the child) than did controls. The only significant diagnostic group difference in perinatal maternal behavior was that mothers diagnosed with depression exhibited more overriding-intrusive behavior than did nonclinical control mothers. Regression modeling results showed that antenatal caregiving representations of “role reversal” predicted significantly lower levels of sensitivity and higher levels of overriding-intrusive behavior independent of the effect of psychopathology. The findings can be interpreted in the context of representational transformation to motherhood during pregnancy. The results provide preliminary evidence for the potential of a new questionnaire measure of caregiving representations as a screening instrument for antenatal representational risk.     

Effects of D- and L-amphetamine on the predatory behavior of Southern grasshopper mice,onychomys torridus

Adult male and female southern grasshopper mice (Onychomys torridus) were tested for predatory aggression toward cricket prey 1 hr after single injections of d-amphetamine (1 or 10 mg/kg) or 1-amphetamine (1 or 10 mg/kg). At the lower dose, d-amphetamine decreased feeding behaviors, while I-amphetamine altered attack-related behaviors. At the higher dose, both stereoisomers appeared to be equipotent in significantly decreasing 5 measures of predatory aggression. These results suggest that brain dopamine and norepinephrine play important roles in the regulation of predatory aggression of Onychomys torridus.     

Holocaust survivors in a primary care setting: fifty years later

Past studies have not assessed the prevalence of emotional disturbances in Holocaust survivors seeking medical treatment in a family practice environment. The present study examined the prevalence of lifetime (the presence of symptomatology at any time) and current posttraumatic stress disorder (PTSD) symptoms, general anxiety, and depression in Holocaust survivors seeking medical treatment in a primary care setting. 20 of the 27 Holocaust survivors in our sample received a current diagnosis of PTSD and reported significant symptoms of depression and general anxiety. Although 74% of the survivors were currently diagnosed with PTSD, participants in this study had reported an overall decline in reexperiencing, hyperarousal, and overall PTSD symptoms but exhibited increased avoidance and numbing symptoms throughout the lifespan. These preliminary results suggest that removing avoidance as a defense mechanism during the course of psychotherapy may leave these survivors without an adequate way for coping with their trauma, subsequently increasing their vulnerability to psychopathology. Implications for psychological interventions are provided.     

HMOs and physician conflicts of interest

In a recent issue of this journal, Francis Beckwith's "The Ethics of Referral Kickbacks and Self-Referral and the HMO Physician as Gatekeeper: An Ethical Analysis" provided an admirably provocative defense of the claim that Health Maintenance Organization (HMO) physician gatekeepers are morally indistinguishable from physician referral kickbacks and self-referrals. Here I will argue that Beckwith's defense is weak. I will also make some tentative suggestions about approaching the issue of physician conflicts of interest.     

Propagation of depth information from local regions in 3-D scenes

The effects of regions with local linear perspective on judgments of the depth separation between two objects in a scene were investigated for scenes consisting of a ground plane, a quadrilateral region, and two poles separated in depth. The poles were either inside or outside the region. Two types of displays were used: motion-parallax dot displays, and a still photograph of a real scene on which computer-generated regions and objects were superimposed. Judged depth separations were greater for regions with greater linear perspective, both for objects inside and outside the region. In most cases, the effect of the region's shape was reduced for objects outside the region. Some systematic differences were found between the two types of displays. For example, adding a region with any shape increased judged depth in motion-parallax displays, but only high-perspective regions increased judged depth in real-scene displays. We conclude that depth information present in local regions affects perceived depth within the region, and that these effects propagate, to a lesser degree, outside the region.     

Organisation: what levels of processing are levels of

The psychology of thought and memory has historically been concerned with a struggle between associationism and its opponents. Organisation theory--in part an offspring of Gestalt concepts--has been the most successful and vocal of these contenders. The levels-of-processing framework has been a part of the effort to overcome associationist predilections. Aspects of principles of organisation and of the recent history of organisation theory are presented, followed by an analysis of the levels-of-processing approach in terms of organisational concepts.     

Pessimism

The problem of pessimism is the secular analogue to the evidential problem of evil facing traditional theism. The traditional theist must argue two things: that the evidence shows that this is on balance a good world and that it is the best possible world. Though the secular optimist who advocates any form of secular moral theory need not argue that the current and future world will likely be the best possible world, she nonetheless must argue that were there a clean solution to the problem of current and future suffering in which all sentient life could be instantly and painlessly eliminated, we would have reasons not to employ the clean solution because the future promises to bring on balance a good world in which the evil of human and animal suffering is outweighed by whatever is good in the world. Pessimism is the view that the evidence argues against secular optimism. It is argued here that it is anything but clear that secular optimism is warranted when viewed from an impersonal point of view. The problem is then evaluated from the personal point of view in which a form of personal optimism is defended even in the face of impersonal pessimism.
