Depressive symptoms during pregnancy: impact on neuroendocrine and neonatal outcomes

Objective

To explore the interplay of maternal depressive symptoms on the infant limbic-hypothalamic-pituitary axis (LHPA) and neurological development.

Design

Pregnant women were monitored for depressive symptoms using the Beck Depression Inventory (BDI) at 28, 32, and 37 weeks of gestation and at delivery. A mixture growth curve analysis divided the women into three risk groups: low/stable, intermediate, and high/increasing depression based on BDI scores. The infant neuroendocrine system was examined using cord blood for adrenocorticotrophic hormone (ACTH) and cortisol measurements. Two-week-old infants were examined using Neonatal Intensive Care Unit Neurobehavioral Scale (NNNS).

Results

Infants born to women of the high/increasing depression group had significant ACTH elevation at birth. On NNNS examination, these infants were more hypotonic and habituated to auditory and visual stimuli.

Conclusion

When compared to non-depressed women, maternal depressive symptoms, even in the absence of major depressive disorder, appeared to facilitate a different developmental pathway for the infant LHPA and early neurological development.     

Risk for suicidal ideation and suicide attempts associated with co-occurring depression and conduct problems in early adolescence

This study investigates the early manifestation of co-occurring depression and conduct problems as a predictor of heightened risk for later suicidal ideation and behavior in a community sample of 521 adolescents. Self-reported symptoms of depression and conduct problems were evaluated in early 6th grade. Suicidal thoughts and behaviors were tracked through multiple assessments carried out over the middle school years. Compared to adolescents with depression symptoms only, conduct problem symptoms only, or low psychopathology, those with co-occurring depression and conduct problem symptoms had the highest risk for subsequent suicidal ideation, recurrent suicidal behaviors, and suicide attempts.     

Exploring the effects of ownership and choice on self-memory biases

Objects encoded in the context of temporary ownership by self enjoy a memorial advantage over objects owned by other people. This memory effect has been linked to self-referential encoding processes. The current inquiry explored the extent to which the effects of ownership are influenced by the degree of personal choice involved in assigning ownership. In three experiments pairs of participants chose objects to keep for ownership by self, and rejected objects that were given to the other participant to own. Recognition memory for the objects was then assessed. Experiment 1 showed that participants recognised more items encoded as "self-owned" than "other-owned", but only when they had been chosen by self. Experiment 2 replicated this pattern when participants' sense of choice was illusory. A source memory test in Experiment 3 showed that self-chosen items were most likely to be correctly attributed to ownership by self. These findings are discussed with reference to the link between owned objects and the self, and the routes through which self-referential operations can impact on cognition.     

The colour of gender stereotyping

Despite legislative attempts to eliminate gender stereotyping from society, the propensity to evaluate people on the basis of their sex remains a pernicious social problem. Noting the critical interplay between cultural and cognitive factors in the establishment of stereotypical beliefs, the current investigation explored the extent to which culturally transmitted colour-gender associations (i.e., pink is for girls, blue is for boys) set the stage for the automatic activation and expression of gender stereotypes. Across six experiments, the results demonstrated that (1) consumer choice for children's goods is dominated by gender-stereotyped colours (Experiment 1); (2) colour-based stereotypic associations guide young children's behaviour (Experiment 2); (3) colour-gender associations automatically activate associated stereotypes in adulthood (Experiments 3-5); and (4) colour-based stereotypic associations bias impressions of male and female targets (Experiment 6). These findings indicate that, despite prohibitions against stereotyping, seemingly innocuous societal practices may continue to promote this mode of thought.     

There are at least two kinds of probability matching: evidence from a secondary task

Probability matching is a suboptimal behavior that often plagues human decision-making in simple repeated choice tasks. Despite decades of research, recent studies cannot find agreement on what choice strategies lead to probability matching. We propose a solution, showing that two distinct local choice strategies—which make different demands on executive resources—both result in probability-matching behavior on a global level. By placing participants in a simple binary prediction task under dual- versus single-task conditions, we find that individuals with compromised executive resources are driven away from a one-trial-back strategy (utilized by participants with intact executive resources) and towards a strategy that integrates a longer window of past outcomes into the current prediction. Crucially, both groups of participants exhibited probability-matching behavior to the same extent at a global level of analysis. We suggest that these two forms of probability matching are byproducts of the operation of explicit versus implicit systems.     

Limitations to the capacity to love

This paper is a meditation on the potential and problems of establishing and maintaining loving and passionate relationships, drawn from a lifetime of struggling with these issues in the course of doing analysis. It describes interferences with the capacity for mature sexual love as reflecting various psychopathological conditions. These limitations include a variety of psychological restrictions determined most frequently by masochistic, narcissistic and paranoid personality features. Clinical case material illustrates both mature and disturbed capability for love relations.     

From Social Construction to Relational Construction: Practices from the Edge

In this paper, I talk about Ken Gergen??s influence in the communication discipline. Beginning with his ground-breaking publications in the 1970??s (Gergen 1973, 1978), we see him challenging the taken for granted separation of theory and practice, scholar and practitioner. One of Ken??s many contributions?Cregardless of disciplinary domain?Chas been the nurturing of forms of practice being developed by creative and innovative practitioners and young scholars alike. There are several key resources that are woven throughout Ken??s work that have continued to inspire and influence practitioners working in mental health, healthcare, organizations, schools, communities, and peace building endeavors. The most central of these resources include (1) centering relational processes which, in turn, generate the expansion of (2) collaborative, participatory practices that embrace alternative worldviews through a (3) a reflexive stance. Ken has challenged himself and all of us to stay on the edge because it is on the edge that new relational possibilities can be created. He has invited us to embrace the edge as the place of great comfort; comfort in knowing that there will always be possibilities for forging new ways of making meaning together.     

Differentiating Adolescent Self-Injury from Adolescent Depression: Possible Implications for Borderline Personality Development

Self-inflicted injury (SII) in adolescence marks heightened risk for suicide attempts, completed suicide, and adult psychopathology. Although several studies have revealed elevated rates of depression among adolescents who self injure, no one has compared adolescent self injury with adolescent depression on biological, self-, and informant-report markers of vulnerability and risk. Such a comparison may have important implications for treatment, prevention, and developmental models of self injury and borderline personality disorder. We used a multi-method, multi-informant approach to examine how adolescent SII differs from adolescent depression. Self-injuring, depressed, and typical adolescent females (n = 25 per group) and their mothers completed measures of psychopathology and emotion regulation, among others. In addition, we assessed electrodermal responding (EDR), a peripheral biomarker of trait impulsivity. Participants in the SII group (a) scored higher than depressed adolescents on measures of both externalizing psychopathology and emotion dysregulation, and (b) exhibited attenuated EDR, similar to patterns observed among impulsive, externalizing males. Self-injuring adolescents also scored higher on measures of borderline pathology. These findings reveal a coherent pattern of differences between self-injuring and depressed adolescent girls, consistent with theories that SII differs from depression in etiology and developmental course.     

Caller characteristics, call contents, and types of assistance provided by caller sex and age group in a Canadian Inuit crisis line in Nunavut, 1991-2001

Analysis of calls made to a northern Canadian Inuit crisis line in the territory of Nunavut between 1991 and 2001 revealed that the majority of users were adult females who called to discuss problems primarily related to relationships and loneliness/boredom. Younger callers tended to make prank calls. The volunteer staff used mostly empathetic listening and suggestions. Referral recommendations made were primarily to social services. Although some callers experienced a language barrier, others found the service to be helpful. Results suggest that the crisis line was underused by young Inuit males who represent a group that are most in need of crisis intervention.     

Aging, imagery, and the bizarreness effect

ABSTRACT This study examined the bizarre imagery effect in young and older adults, under incidental and intentional conditions. Intentionality was manipulated across experiments, with participants receiving an incidental free recall test in Experiment 1 and an intentional test in Experiment 2. This study also examined the relation between working memory resources and the bizarreness effect. In Experiment 1 young and older adults were presented with common and bizarre sentences; they later received an incidental recall test. There were no age differences in sensitivity to the bizarreness effect in Experiment 1 when ANOVAs were used to analyze the data. However, when the bizarreness effect was examined in terms of effect size, there was evidence that younger adults produced larger bizarreness effect sizes than younger adults. Experiment 2 further explored age differences in sensitivity to the bizarreness effect by presenting young and older adults with bizarre and common sentences under intentional learning conditions. Experiment 2 failed to yield age differences as a function of item type (bizarre vs. common). In addition, Experiment 2 failed to yield significant evidence that the bizarreness effect is modulated by working memory resources. The results of this study are most consistent with the distinctiveness account of the bizarreness effect.
