Presymptomatic Genetic Testing with an APP Mutation in Early-Onset Alzheimer Disease: A Descriptive Study of Sibship Dynamics

Early-onset Alzheimer disease (AD) accounts for only 5% of all cases of Alzheimer disease. To date, mutations in three different genes, the Amyloid precursor protein (APP), Presenilin 1 (PS1), and Presenilin 2 (PS2), have been identified as causative in early-onset AD, making predictive testing possible. Predictive testing for early-onset Alzheimer disease is a relatively new phenomenon. This paper describes the process of identifying a new mutation in the APP gene associated with early-onset AD, notifying family members, and offering participation in research as well as predictive testing. The goal is to share the complexities of predictive testing in a sibship newly identified as being at risk for an adult-onset, incurable neurodegenerative disease.     

The Effect of Target Age on the Activation of Gender Stereotypes

Two studies investigated the impact of target age on gender stereotyping. Study 1 examined whether the attribution of gender-stereotypical traits to unfamiliar individuals varies as a function of target and participant age. Adults and children (ages 8–10 years) viewed photographs of men, women, boys, and girls and rated each pictured individual on the possession of masculine, feminine, and gender-neutral personality traits. Both adult and child participants showed evidence of gender stereotyping. The strongest level of stereotyping was seen when adults rated child targets. Adults were particularly unwilling to attribute feminine characteristics to males. Finally, participants of both ages viewed adult targets (regardless of sex) as more masculine and less feminine than child targets. Study 2 examined the generality of the latter finding. Adult participants rated traditionally masculine and feminine traits on the likelihood of possession by adults versus children. Confirming the results of Study 1, feminine traits were believed to be more childlike/less adultlike than were masculine traits. Implications for gender-role development, socialization, and measurement are discussed.     

No Sissy Boys Here: A Content Analysis of the Representation of Masculinity in Elementary School Reading Textbooks

In this study, we investigate the portrayal of gender characteristics in elementary school reading textbooks. Over the past 25 years, most of the research on textbooks has focused on female roles and characteristics. In this research, we focus particularly on how males are portrayed. Using an evaluative instrument based on the Bem Sex Role Inventory, we examine first, third, and fifth grade literature textbooks. In particular, we analyze traits pertaining to masculine and feminine stereotypes. Our results show that despite publisher's guidelines and Title IX, males are still primarily portrayed in a stereotypical light. Males are overwhelming shown to be aggressive, argumentative, and competitive.     

The role of expectation and memory‐retrieval techniques in the construction of beliefs about past events

This study assessed social factors affecting the elicitation of false reports for events occurring the day after birth. High, medium and low hypnotizable participants (N=170) were randomly assigned to hypnotic, guided imagery (non‐hypnotic), expectancy or control conditions. Participants were led to believe that they had experienced a specific event on the day after birth. Hypnotic and guided imagery participants were age regressed, while participants in the expectancy condition were provided with cues suggesting access to this memory was feasible. Relative to controls, these participants recalled higher levels of day‐after‐birth reports, although age‐regressed participants reported significantly more event specific details than expectancy participants. Furthermore, high and medium hypnotizables were more likely than low hypnotizables to recall events occurring the day after birth. Implications of this study within the therapeutic setting are discussed. Copyright © 2000 John Wiley & Sons, Ltd.     

Embedding prevention services within systems of care: Strengthening the nexus for children

System-of-care models that offer a continuum of integrated mental health services for children are being widely implemented in local communities. Preventive services, arising from the theoretically grounded prevention sciences, are an important but neglected component of this model. Studies of the use of mental health services by children are reviewed, and an integrative model is proposed to incorporate prevention services as a component of the child mental health service system. Construction of the prevention sciences has followed a linear phase model that has advantages and disadvantages for bridging prevention sciences and services research. As prevention science progresses into broader field tests of its effectiveness, studies of child services can be informative, especially in advancing the applicability and dissemination of research findings. Future directions are outlined to strengthen the nexus between services research and prevention science, and to construct a new genre of prevention services research.     

W. E. B. Du Bois’s “Conservation of Races”

Nothing was more important for W. E. B. Du Bois than to promote the upward mobility of African Americans. This essay revisits his “Conversation of Races” to demonstrate its general philosophical importance. Ultimately, Du Bois’s three motivations for giving the address reveal his view of the nature of philosophical inquiry: to critique earlier phenotypic conceptions of race, to show the essentiality of history, and to promote a reflexive practice. Commentators have been unduly invested in the hermeneutic readings and as a result have misunderstood its philosophical dimensions. Du Bois did more than introduce the concept of race into the purview of philosophy, he provided a method for philosophical inquiry into a concept that is notoriously difficult to approach with precision. The goal here is to show why no introduction to philosophy and no discussion about the nature of philosophical inquiry is complete without consideration of “Conservation.” Certainly, it is a text about race, but it is also an important philosophical text in general.     

Negativity bias in false memory: moderation by neuroticism after a delay

The negativity bias is the tendency for individuals to give greater weight, and often exhibit more rapid and extreme responses, to negative than positive information. Using the Deese-Roediger-McDermott illusory memory paradigm, the current study sought to examine how the negativity bias might affect both correct recognition for negative and positive words and false recognition for associated critical lures, as well as how trait neuroticism might moderate these effects. In two experiments, participants studied lists of words composed of semantic associates of an unpresented word (the critical lure). Half of the lists were comprised of positive words and half were comprised of negative words. As expected, individuals remembered negative list words better than positive list words, consistent with a negativity bias in correct recognition. When tested immediately (Experiment 1), individuals also exhibited greater false memory for negative versus positive critical lures. When tested after a 24-hr delay (Experiment 2), individuals higher in neuroticism maintained greater false memory for negative versus positive critical lures, but those lower in neuroticism showed no difference in false memory between negative and positive critical lures. Possible mechanisms and implications for mental health disorders are discussed.     

Effects of preference on performing a self-care skill among children with autism spectrum disorder

In this study, four children with autism were assessed to determine their preference choices for toothbrushes and toothpastes included during self-care skills teaching sessions. For two of the children, the presence of high-preference (HP) materials was associated with improved independent tooth brushing when compared to the presence of low-preference (LP) materials. There was no difference in independent tooth brushing between HP/LP conditions for the other two children. These findings suggest that preference and choice of materials alone can be a helpful instructional strategy for care providers serving children who have neurodevelopmental disorders and skill deficits.

Identity Status Change Within Personal Style Clusters: A Longitudinal Perspective From Early Adulthood to Midlife

Differences in identity stability and change from age 36 through 42 to 50 were examined between three male and female personal style clusters extracted at age 27. We expected, first, the identity statuses to consistently differ between the clusters and, second, those with the least mature identity to move closer to others during midlife. Differences between the personal style clusters were discovered on all identity statuses across ages. Although significant personal style × age interactions were not detected, some evidence of pace-of-development differences emerged for women: Initial differences in identity maturation between the female groups partially leveled off by midlife. In men, early adulthood identity maturation in the conflicted group was however followed by a re-decline in later midlife.
