Childbearing depressive symptomatology in high–risk pregnancies: The roles of working models and social support

Guided by both attachment and social support theories, the authors conducted a longitudinal investigation exploring the concomitant effects of perceptions of spouse support (anticipated and received spouse support) and internal working models of attachment (positive–self and positive–other), on childbearing depressive symptomatology. Distinct main and interaction effects for attachment dimensions and perceived support variables were hypothesized for high– and low–risk pregnancies. Participants in the final sample were 200 pregnant women who completed the self–report between the 25th and the 29th weeks of pregnancy, and 8 weeks after childbirth. Controlling for initial levels of depressive symptoms and health conditions, results demonstrated the protective role of high levels of received support and of positive–other models on childbirth depressive symptoms. Moreover, received support and models of positive–other were found to interact with health conditions, producing distinct moderation effects: Received support was found to be a significantly stronger protective factor for childbearing depression among women with low–risk pregnancies; positive–other models were found to be a significantly stronger protective factor among women with high–risk pregnancies. The implications of these findings for the understanding of intrapersonal and interpersonal factors in successful coping with a health risk situation are discussed.     

Effects of meaning training on overcoming functional fixedness

Functional fixedness (FF) consists in focusing on some function of an object while overlooking another necessary for problem solving. Assuming that FF occurs when too few meanings are assigned to the major problem aspects, it was hypothesized that widening the scope of meaning would reduce FF, particularly in subjects providing more responses. The task was completing two electrical circuits. Meaning training consisted in requesting the subjects to provide responses to questions reflecting 11 meaning variables concerning three referents of the task. The subjects were 64 high school girls about 15 years old, only half of whom got meaning training. The results showed that meaning training reduced FF: the experimental subjects solved the target task faster, especially if they assigned more direct or indirect function responses to the target referents. Discussion centered on the effects of specific and nonspecific meaning training on different phases of problem solving. This study is based partly on the data presented by the first author in partial fulfillment of the requirements for a master’s degree at the Department of Psychology, Tel Aviv University.     

The effect of prenatal hypoxia on brain development: short- and long-term consequences demonstrated in rodent models

Hypoxia (H) and hypoxia-ischemia (HI) are major causes of foetal brain damage with long-lasting behavioral implications. The effect of hypoxia has been widely studied in human and a variety of animal models. In the present review, we summarize the latest studies testing the behavioral outcomes following prenatal hypoxia/hypoxia-ischemia in rodent models. Delayed development of sensory and motor reflexes during the first postnatal month of rodent life was observed by various groups. Impairment of motor function, learning and memory was evident in the adult animals. Activation of the signaling leading to cell death was detected as early as three hours following H/HI. An increase in the counts of apoptotic cells appeared approximately three days after the insult and peaked about seven days later. Around 14-20 days following the H/HI, the amount of cell death observed in the tissue returned to its basal levels and cell loss was apparent in the brain tissue. The study of the molecular mechanism leading to brain damage in animal models following prenatal hypoxia adds valuable insight to our knowledge of the central events that account for the morphological and functional outcomes. This understanding provides the starting point for the development and improvement of efficient treatment and intervention strategies.     

A Full Circle: Psycho-dynamic Understanding and Systems Theory

Two papers published in 1979 are reviewed, one which looked at theories of family interaction and techniques of intervention, and the other at developments of the focal approach to family therapy which has its base in a dynamic understanding of the nature of relationships, but uses a variety of systemic interventions to create change. The development of the approach is described, along with its application to work in the abuse field. A recent case where two daughters were sexually abused by the grandfather who had abused their mother is used as an illustration.     

Self-criticism,interpersonal conditions,and biosystemic inflammation in suicidal thoughts and behaviors within mood disorders: A bio-cognitive-interpersonal hypothesis

We review the theoretical and empirical literature on the role of self-concept in suicidal behavior in the context of mood disorders (i.e., unipolar depression and bipolar spectrum disorders). The main themes emanating from this review are then juxtaposed against (a) the Interpersonal-Psychological Theory of Suicide and (b) biological research on the role of inflammatory processes in suicidality. Such a juxtaposition paves the way for a bio-cognitive-interpersonal hypothesis. Pathologies of the self-concept—primarily self-criticism—propel mood disorder sufferers to generate interpersonal stress that culminates in two proximal causes of suicidality: thwarted belongingness and perceived burdensomeness. In turn, these two interpersonal conditions set in motion systemic biosystemic inflammation, serving as a proximal cause for suicidality in mood disorders. We conclude by describing a research project aimed at testing this hypothesis, and by outlining pertinent implications for assessment, treatment, and prevention.     

On the misperception of variability

It has long been claimed that people perceive the world as less variable and more regular than it actually is. Such misperception, if shown to exist, could explain some perplexing behaviors. However, evidence supporting the claim is indirect, and there is no explanation of its cause. As a possible cause, the authors suggest that people use sample variability as an estimate of population variability. This is so because the sampling distribution of sample variance is downward attenuated, the attenuation being substantial for sample sizes that people consider. Results of 5 experiments show that people use sample variability, uncorrected for sample size, in tasks in which a correction is normatively called for, and indeed perceive variability as smaller than it is.
