Gender-role adoption and sex as academic and psychological risk factors

Five hundred and ten first-year junior high school students were administered a battery of psychological tests. On the basis of their scores from two gender-role adoption measures, three smaller groups were extracted within each biological sex: masculine, feminine, and undifferentiated individuals. Feminine students reported a greater amount of discomfort (vulnerability). A battery of tests administered toward the end of that school year revealed that females attained greater neuroticism and alienation scores than did their male peers. Possible explanations for this pubescent self-report of maladjustment are the more masculine orientation of the junior high school in comparison to the elementary school and the menarche.The authors wish to thank Ms. S. Chesterman, Regional Director of the Montreal Catholic School Commission, and Mr. K. Quinn, Principal of Sir Wilfred Laurier Junior High School, for granting us permission to disrupt school activities in order to test their students. We also wish to acknowledge the assistance of the following members of Sir Wilfred Laurier: Mr. O. Hruby, Vice-Principal; Sr. G. Larocque, Vice-Principal; Mr. S.

Conceptualizing and measuring personality vulnerability to depression: comment on Coyne and Whiffen (1995)

J. C. Coyne and V. E. Whiffen (1995) reviewed research on personality vulnerability to depression, focusing on S. J. Blatt's (1974, 1990) concepts of dependency and self-criticism and A. T. Beck's (1983) concepts of sociotropy and autonomy. The authors discuss 6 issues raised in that review: (a) the typological or dimensional nature of vulnerability, (b) the theoretical implications of "mixed" vulnerability, (c) the relations of vulnerability to Neuroticism. (d) the potential confounding of vulnerability with concurrent depression, (e) the potential confounding of vulnerability with social context, and (f) the differentiation of dependency from relatedness. The authors conclude that Blatt's and Beck's concepts are continuous, nearly orthogonal dimensions that can be identified and measured independently from Neuroticism, depression, and social context.     

Dopamine, working memory, and training induced plasticity: implications for developmental research

Cognitive deficits and particularly deficits in working memory (WM) capacity are common features in neuropsychiatric disorders. Understanding the underlying mechanisms through which WM capacity can be improved is therefore of great importance. Several lines of research indicate that dopamine plays an important role not only in WM function but also for improving WM capacity. For example, pharmacological interventions acting on the dopaminergic system, such as methylphenidate, improve WM performance. In addition, behavioral interventions for improving WM performance in the form of intensive computerized training have recently been associated with changes in dopamine receptor density. These two different means of improving WM performance--pharmacological and behavioral--are thus associated with similar biological mechanisms in the brain involving dopaminergic systems. This article reviews some of the evidence for the role of dopamine in WM functioning, in particular concerning the link to WM development and cognitive plasticity. Novel data are presented showing that variation in the dopamine transporter gene (DAT1) influences improvements in WM and fluid intelligence in preschool-age children following cognitive training. Our results emphasize the importance of the role of dopamine in determining cognitive plasticity.     

Breaking the Cyber-Security Dilemma: Aligning Security Needs and Removing Vulnerabilities

Current approaches to cyber-security are not working. Rather than producing more security, we seem to be facing less and less. The reason for this is a multi-dimensional and multi-faceted security dilemma that extends beyond the state and its interaction with other states. It will be shown how the focus on the state and “its” security crowds out consideration for the security of the individual citizen, with detrimental effects on the security of the whole system. The threat arising from cyberspace to (national) security is presented as possible disruption to a specific way of life, one building on information technologies and critical functions of infrastructures, with relatively little consideration for humans directly. This non-focus on people makes it easier for state actors to militarize cyber-security and (re-)assert their power in cyberspace, thereby overriding the different security needs of human beings in that space. Paradoxically, the use of cyberspace as a tool for national security, both in the dimension of war fighting and the dimension of mass-surveillance, has detrimental effects on the level of cyber-security globally. A solution out of this dilemma is a cyber-security policy that is decidedly anti-vulnerability and at the same time based on strong considerations for privacy and data protection. Such a security would have to be informed by an ethics of the infosphere that is based on the dignity of information related to human beings.     

Subjectivity in Motion: Caribbean Women's (Dis)Articulations of Being from Fanon/Capécia to the Wonderful Adventures of Mrs. Seacole in Many Lands

In this essay I show that texts by early Caribbean women writers, such as the Wonderful Adventures of Mrs. Seacole in Many Lands, reveal and resist the effects of colonial paradigms by leaving textual traces of how such paradigms can effectively be countered and overturned. I arrive at such a reading of Seacole via an analysis of Frantz Fanon's (mis)reading of Mayotte Capécia's turn‐of‐the‐century novel, Je suis martiniquaise, in light of advances in postcolonial and feminist theory. I argue that doing so can bring us to recognize the contributions that early writings by Caribbean women have made to a broader understanding of the nature of being, across differences of “race,” class, and geography. I consider how we might recover in Capécia important models that Fanon himself replicates, yet dismisses, that predate Capécia's own text and that can be located in a text like Seacole's. In the end, I come to contend that Mary Seacole's text is more than a mere record of a “free colored” woman's life in the second half of the nineteenth century. It is, to use today's postcolonial parlance, an interventionist, hybrid text that attempts to subvert dominant discourse while participating in its circuits.     

A Lifespan Perspective on Dependency and Self-Criticism: Age-Related Differences from 18 to 59

A sizeable body of research suggests that self-definition and relatedness represent two fundamental developmental streams across the lifespan (Blatt in Psychoanal Study Child 29:107–157, 1974; Blatt and Luyten in Dev Psychopathol 21:793–814, 2009). Adverse developmental experiences have been found to affect personality development leading to high levels of self-criticism or dependency. No research to date has examined the developmental trends of these factors across the lifespan or the moderating impact of important life experiences. In a sample of 3,586 Canadians aged 18–59, age-related differences in self-criticism and dependency were examined. Analyses were replicated in a multicultural sample of 612 Canadians and 647 individuals born and currently living on the continent of Asia. Controlling for both neuroticism and depressive symptoms, results showed that self-criticism and dependency decreased linearly across the lifespan in both samples and across cultures; however, the decrease in self-criticism was steeper for men compared to women, while the decrease in dependency was steeper for those without children compared to those with children. Furthermore, participants who were in a romantic relationship showed lower levels of self-criticism and higher levels of dependency compared to those who were not in a romantic relationship. Results suggest that people may develop a healthier view of close relationships with others and acquire more positive self-views over the course of their lives.     

Emotion regulation through listening to music in everyday situations

Music is a stimulus capable of triggering an array of basic and complex emotions. We investigated whether and how individuals employ music to induce specific emotional states in everyday situations for the purpose of emotion regulation. Furthermore, we wanted to examine whether specific emotion-regulation styles influence music selection in specific situations. Participants indicated how likely it would be that they would want to listen to various pieces of music (which are known to elicit specific emotions) in various emotional situations. Data analyses by means of non-metric multidimensional scaling revealed a clear preference for pieces of music that were emotionally congruent with an emotional situation. In addition, we found that specific emotion-regulation styles might influence the selection of pieces of music characterised by specific emotions. Our findings demonstrate emotion-congruent music selection and highlight the important role of specific emotion-regulation styles in the selection of music in everyday situations.     

Happiness vs. mindfulness exercises for individuals vulnerable to depression

An online ‘positivity’ exercise involving the practice of discrete positive emotions was pitted against a mindfulness meditation exercise and an active placebo control. The effects of positivity and meditation were examined in relationship to personality variables known to entail vulnerability to depression. Participants (N = 741) were randomly assigned to the positivity, mindfulness, or control condition. They completed their exercise for three weeks and were assessed on measures of subjective well-being at baseline, post-test, and one, and two months later. Results indicated that all groups showed significant decreases in depressive symptoms from baseline to two months. The positivity exercise uniquely predicted increases in meaning, pleasure, engagement, and satisfaction in life across follow-ups. Dependent individuals responded favorably to the positivity intervention in the short run, but worsened in the long run for pleasure-related happiness. Self-criticism was associated with significantly greater gains in life satisfaction following exercise completion.     

Short-term memory performances during sustained wakefulness in patients with obstructive sleep apnea-hypopnea syndrome

Both working and immediate memories were assessed every 4h by specific short-term memory tasks over sustained wakefulness in 12 patients with obstructive sleep apnea and hypopnea syndrome (OSAHS) and 10 healthy controls. Results indicated that OSAHS patients exhibited lower working memory performances than controls on both backward digit span and complex Sternberg tasks. Speed and accuracy on Sternberg tasks were affected by memory load in both groups. However, immediate memory was not impaired in OSAHS patients. Diurnal and nocturnal SaO(2) were correlated with speed and accuracy high-speed memory scanning performance on Sternberg tasks in patients. These results suggest specific working memory deficits associated with OSAHS over sustained wakefulness with a possible deficiency in the central executive responsible for the higher information processing, in addition to a potentially insufficient storage capacity. Among OSAHS patients, working memory ability involved in high-speed memory scanning may be impaired by chronic hypoxemia.
