Visuomotor binding in older adults

Action integration is the process through which actions performed on a stimulus and perceptual aspects of the stimulus become bound as a unitary object. This process appears to be controlled by the dopaminergic system in the prefrontal cortex, an area that is known to decrease in volume and dopamine functioning in older adults. Although the decline should lead to reduced action integration in older adults, we found equivalent integration in both young and older adults. This indicates that older adults may be able to compensate for their dopaminergic deficiencies by activating additional neural networks that are not used by young adults.     

Advances,Problems, and Challenges in the Study of Emotion Regulation: A Commentary

As observed by Zinbarg and Mineka (American Psychologist 62:259–261, 2007), the study of emotion regulation faces significant challenges that need to be addressed. In reviewing the articles in the present issue, we comment upon how researchers have attempted, with varying degrees of success, to meet these challenges. We suggest that the articles in the present volume demonstrate important conceptual and methodological advances in emotion regulation research, but that the most central problems noted by Zinbarg and Mineka have yet to be fully remedied. In highlighting both the progress made and problems faced by the field of emotion regulation, we suggest new directions for future research in this area.     

Neighborhood Disadvantage, Parent–Child Conflict, Neighborhood Peer Relationships, and Early Antisocial Behavior Problem Trajectories

  This study examined relations among neighborhood disadvantage, parent–child conflict, deviant peer involvement in the neighborhood, and early-starting antisocial trajectories. Antisocial group patterns were identified in 218 low-income boys followed from ages 5 to 11, and neighborhood and family variables were evaluated as predictors in early and middle childhood. Four trajectory groups emerged: one increasing pattern that corresponded with developmental theories of early-starting antisocial behavior; one with initially high and decreasing problems over time; and two low antisocial groups. Parent–child conflict and neighborhood disadvantage were significantly associated with trajectory patterns, with youth in the 2 higher antisocial behavior groups characterized by more neighborhood problems and parent–child conflict than other groups. The results suggest that in early childhood, neighborhood disadvantage and family conflict place children at risk for early-starting trajectories, and that involvement with deviant peers in the neighborhood takes on an increasingly important role in patterns of antisocial behavior over middle childhood.     

LOOKING GOOD, SOUNDING GOOD: FEMININITY IDEOLOGY AND ADOLESCENT GIRLS' MENTAL HEALTH

This study used a feminist psychodynamic developmental framework to test the hypothesis that internalizing conventional femininity ideologies in two domains—inauthenticity in relationships and body objectification—is associated with early adolescent girls' mental health. One hundred forty-eight eighth-grade girls completed measures of femininity ideology, self-esteem, depression, and demographic characteristics. In the first part of this study, we refined the Adolescent Femininity Ideology Scale originally developed by Tolman and Porche (2000) . In the second part, we used structural equation modeling to test models linking femininity ideology to mental health. Results revealed that body objectification, and to a lesser extent, inauthenticity in relationships, accounted for half of the variance in depression and over two-thirds of the variance in self-esteem in a critical period of development for adolescent girls. The importance of a feminist psychodynamic developmental framework for identifying and understanding salient dimensions of female adolescence is discussed.     

Age and individual differences in working memory: the size judgment span task

The authors introduced the Size Judgment Span (SJS) task, a working memory measure developed for use with persons of varied educational backgrounds and general intellectual ability. The authors pooled data from 5 published articles where the SJS task and other measures of cognitive performance were administered to create an archival data set with 496 participants. Analyses of these data yielded strong evidence of age and individual ability differences in SJS performance, confirming the sensitivity of this task for empirically distinguishing age and ability groups. The SJS was also significantly correlated with the backward digit span and listening span tasks. Using hierarchical regression analyses, the authors examined the SJS task as a predictor of different forms of episodic memory, including spatial location memory, verbal free recall, and recognition memory. Results confirmed the practical utility and predictive validity of the SJS task. The authors considered implications for current theoretical views of working memory.     

Changing and diverse roles of women in American Indian cultures

This article explores traditional and contemporary sex roles of Indian women. It emphasizes the renewing power of the feminine—a creative, healing balance that arises as traditional and contemporary strengths are brought together. The survival of the extended family throughout two hundred years of governmental policy attests to Indian women's resilience despite continuous role readjustment, value conflict, and economic pressure. Tribal diversity and predominantly egalitarian structural similarities are affirmed in this work through reviews of ethnographic studies addressing the roles of Indian women prior to European contact. The conventional and alternative roles of Indian women in traditional times are examined with an eye toward the spiritual source of Indian women's strength. Studies outlining the emotional and spiritual costs of contemporary Indian women living bicultural lifestyles, especially those pursuing advanced educational training, highlight the continued use of traditional Indian coping mechanisms. Finally, the current movement toward retraditionalization of roles of Indian women as caretakers and transmitters of cultural knowledge is posited as an effective means of overcoming problems and achieving Indian self-determination.We would like to thank Myra Strober and Janet Sorrel for their helpful comments concerning earlier versions of this article.     

Altering "motivational" variables alters induction produced by upcoming food-pellet reinforcement

Previous research has demonstrated that rats will increase their rates of lever pressing for sucrose rewards in the first half of an experimental session when food pellets, rather than the same sucrose, continually serve as the reward in the second half of the session. This effect has been coined induction, and the present study investigated whether it could be altered by altering "motivational" variables. Experiment 1 manipulated subjects' motivation by altering, across conditions, their level of food deprivation. Predictably, the size of induction varied directly with level of deprivation. Experiments 2 and 3 manipulated subjects' motivation by feeding them food pellets and sucrose, respectively, prior to their responding in the experimental session. These pre-session feedings decreased the size of the observed induction in both experiments. The results from the present study indicate that the size of induction is correlated with subjects' motivation to respond for the available reinforcers. They are also consistent with the idea that operant processes underlie the effect. The notion that induction might encompass the concept of "anticipation" is also discussed.

“I Don’t Want to Be an Ostrich”: Managing Mothers’ Uncertainty during BRCA1/2 Genetic Counseling

Families who face genetic disease risk must learn how to grapple with complicated uncertainties about their health and future on a long-term basis. Women who undergo BRCA 1/2 genetic testing describe uncertainty related to personal risk as well as their loved ones’, particularly daughters’, risk. The genetic counseling setting is a prime opportunity for practitioners to help mothers manage uncertainty in the moment but also once they leave a session. Uncertainty Management Theory (UMT) helps to illuminate the various types of uncertainty women encounter and the important role of communication in uncertainty management. Informed by UMT, we conducted a thematic analysis of 16 genetic counseling sessions between practitioners and mothers at risk for, or carriers of, a BRCA1/2 mutation. Five themes emerged that represent communication strategies used to manage uncertainty: 1) addresses myths, misunderstandings, or misconceptions; 2) introduces uncertainty related to science; 3) encourages information seeking or sharing about family medical history; 4) reaffirms or validates previous behavior or decisions; and 5) minimizes the probability of personal risk or family members’ risk. Findings illustrate the critical role of genetic counseling for families in managing emotionally challenging risk-related uncertainty. The analysis may prove beneficial to not only genetic counseling practice but generations of families at high risk for cancer who must learn strategic approaches to managing a complex web of uncertainty that can challenge them for a lifetime.     

SOIL CARBON TRANSFORMATIONS

Climate change is a wicked problem with causes and consequences overlapping with other wicked problems and no single solution (Hulme 2015). For example, the frequent droughts associated with climate change exacerbate another major problem facing humanity as we enter the Anthropocene: how to produce adequate food to feed a growing population without increasing pollution or “more food with low pollution (MoFoLoPo)” (Davidson et al. 2015). Soils represent an intersection of these two wicked problems, because they are integral to food production through agriculture and also are an important component of global climate models. Recent focus in the field of soil carbon cycling has facilitated a transformation in our understanding of the processes that control this important resource. This understanding is critical to responding to both wicked problems.
