Attentional control moderates fearful responding to a 35% CO(2) challenge

Attentional control (AC) is an individual difference variable indexing the ability to voluntarily focus attention and shift attention when desired. AC is thought to impact the experience of fear by facilitating the disengagement of attention from threat and promoting the deployment of attentional resources toward regulatory or coping strategies. Whereas previous research has focused on visual threat cues, in the current study we examined whether this model also applies to interoceptive threat by evaluating the extent to which individual differences in AC moderated the relationship between trait anxiety and self-reported fear in response to a single vital capacity inhalation of a 35% CO(2), 65% balanced O(2) gas mixture. The sample comprised a large nonclinical group of young adults (N=128). Results indicated that AC moderated the relationship between trait anxiety and fearful responding to the challenge. Findings suggest that AC plays a significant and clinically important role in modulating self-reported fear.     

Spirituality and Religiosity in Urban Adolescents with Asthma

Predictors of multiple dimensions of spirituality/religiosity (S/R) and adolescents’ preferences for having S/R (e.g., prayer) addressed in hypothetical medical settings were assessed in a sample of urban adolescents with asthma. Of the 151 adolescents (mean age = 15.8, 60% female, 85% African-American), 81% said that they were religious and spiritual, 58% attended religious services in the past month, and 49% prayed daily. In multivariable models, African-American race/ethnicity and having a religious preference were associated with higher levels of S/R (R ² = 0.07–0.25, P < .05). Adolescents’ preferences for including S/R in the medical setting increased with the severity of the clinical situation (P < .05).     

Contrast polarity preservation's role in perception: explained and unexplained stimuli

Roncato and Casco (2003, Perception & psychophysics 65 1252-1272) had shown that in situations where the Gestalt principle of good continuity is put into conflict with preservation of contrast polarity (CP) the perception that preserves CP prevails. Parlangeli and Roncato (2010, Perception 39 255-259) have studied this question of preservation of CP more closely and have added an addendum to the rule. They have used stimuli consisting of a checkerboard of perpendicularly arranged rectangular bricks (white, gray, or black) and draughtsmen white, gray, or black disks placed at the corners of the bricks. This study has caused them to add an addendum to the rule of CP-preserved path-conjunction binding: if there are two contour completions that preserve the CP, the one with the higher contrast will prevail. Parlangeli and Roncato find that, for certain shades of the disks and bricks, the perpendicular lines of the checkerboard appear strikingly to be slanted or undulating. Here we consider all possible arrangements of relative magnitudes of checkerboards consisting of bricks of two different shades and disks of two shades as well, as such arrangements with widely varying differences in the magnitude of brightness. We have found a number of cases where the perception is not explained by the rule and addendum of Roncato and Casco, and Parlangeli and Roncato, and a case where preservation of "distant" as well as local CP plays a role in perception. The previously known cases, and the new exceptional unexplained stimuli we have found, warrant further study.     

A horse of a different color: how formulation influences medication effects

A medication's pharmacokinetic properties can be as important as its efficacy in determining how successful a treatment is. Formulation plays a critical role in absorption, distribution, and elimination of a drug, which in turn can influence the clinical profile of a medication, including onset and duration of action, consistency of plasma levels, ability to cross the blood-brain barrier, and other factors. Advances in drug delivery technology mean that formulation is now an integral component in the development of a drug. Likewise, formulation is one of the factors that may influence selection of a medication to suit the needs of a particular patient. This article briefly reviews the technologies commonly applied in the development of psychotropic medications, with emphasis on the various oral modified-release formulations, and discusses how formulation can be used to optimize the efficacy and tolerability of psychotropic drugs.     

Factors influencing young children's risk of unintentional injury: Parenting style and strategies for teaching about home safety

This study examined mothers' teaching about home-safety issues to 24–30 month and 36–42 month old children, explored the relationship of teaching strategies to parenting styles, and assessed how these factors are related to children's risk of unintentional injury. A structured interview assessed home-safety issues relevant to falls, burns, cuts, poisoning, and suffocation/strangulation/choking. Mothers identified safety issues relevant to her child, and indicated the type and extent to which she utilized teaching as a strategy to address each safety issue. Standardized questionnaires provided information about parenting style and children's history of injuries. Results revealed that mothers' endorsements of home-safety issues did not vary with child age, mothers used teaching to manage safety issues for all types of injuries, and type of teaching strategy (explanations, rules, behavior modification) varied with parenting style. Greater use of explaining and less rule usage was linked to permissive parenting; these teaching strategies predicted children's medically-attended injury among highly-permissive mothers. Thus, teaching about safety is a common risk-management strategy mothers use to address hazards in the home. However, the specific type of teaching strategy used varies with parenting style, which has implications for children's risk of injury.     

Are Traditional Gender Role Attitudes Associated With Risky Sexual Behavior and Condom-related Beliefs?

Traditional gender role attitudes, which emphasize an unequal distribution of power in the family and stereotypical norms about masculinity, may be associated with unsafe sexual behavior and beliefs in young men and women. This study was designed to examine associations between gender role attitudes including gender-based family role attitudes and masculinity ideology, sexual behaviors, and condom-related beliefs in a sample of sexually active college students (N = 154). Family role attitudes were related to risky condom-related beliefs but not to risky sexual behavior. Masculinity ideology was related to both sexual behaviors and condom-related beliefs but, in some cases, in a direction opposite to that predicted. These unexpected findings and the utility of examining masculinity ideology among women are discussed.An earlier version of this paper was presented at the 2002 Biennial Meeting of the Society for Research on Adolescence, New Orleans, Louisiana.     

Combining computer adaptive testing technology with cognitively diagnostic assessment

A major advantage of computerized adaptive testing (CAT) is that it allows the test to home in on an examinee's ability level in an interactive manner. The aim of the new area of cognitive diagnosis is to provide information about specific content areas in which an examinee needs help. The goal of this study was to combine the benefit of specific feedback from cognitively diagnostic assessment with the advantages of CAT. In this study, three approaches to combining these were investigated: (1) item selection based on the traditional ability level estimate (theta), (2) item selection based on the attribute mastery feedback provided by cognitively diagnostic assessment (alpha), and (3) item selection based on both the traditional ability level estimate (theta) and the attribute mastery feedback provided by cognitively diagnostic assessment (alpha). The results from these three approaches were compared for theta estimation accuracy, attribute mastery estimation accuracy, and item exposure control. The theta- and alpha-based condition outperformed the alpha-based condition regarding theta estimation, attribute mastery pattern estimation, and item exposure control. Both the theta-based condition and the theta- and alpha-based condition performed similarly with regard to theta estimation, attribute mastery estimation, and item exposure control, but the theta- and alpha-based condition has an additional advantage in that it uses the shadow test method, which allows the administrator to incorporate additional constraints in the item selection process, such as content balancing, item type constraints, and so forth, and also to select items on the basis of both the current theta and alpha estimates, which can be built on top of existing 3PL testing programs.     

The Role of Teacher Cognition and Behavior in Children’s Peer Relations

This study explored the role of the classroom teacher in peers’ evaluations of liking and disliking of their classmates. Teacher cognitions about children (teacher liking of students, teacher attributions for aggressive student behavior) and teacher behavior toward children (positive, corrective/negative) were examined as mediators in the link between children’s own behavior (aggression, prosocial behavior) and peer liking and disliking. Participants were 127 second-graders in 12 classrooms (64 males, 63 females). Data on child behavior were collected through peer and teacher report, data on teacher cognitions about children were collected through self report, data on teacher behavior toward children were collected through naturalistic classroom observations, and data on peer liking and disliking were collected through peer nominations. Data were analyzed using path analysis. Results indicated that teacher cognitions about children and corrective/negative teacher behavior toward children mediated the relations between aggressive and prosocial child behavior and peer disliking.     

Criminal Crews,Codes, and Contexts: Differences and Similarities across the Code of the Street,Convict Code,Street Gangs,and Prison Gangs

We use 16 characterizations of crews, codes, and contexts to determine if offender subcultures (code of the street, convict code, street and prison gangs) converge, complement, or are independent of one another. We find extensive overlap across offender subcultures with “belief” subcultures in street and prison settings mirroring the “group” subcultures in those respective settings. Findings generate a call for comparative research on the convergences and divergences across subcultures on the street and in prisons with a specific emphasis on the impact that importation, deprivation, and exportation have on policy and programming importation for both the street and prison settings.     

Doing Gender Online: New Mothers’ Psychological Characteristics,Facebook Use,and Depressive Symptoms

Online social networking sites, such as Facebook, have provided a new platform for individuals to produce and reproduce gender through social interactions. New mothers, in particular, may use Facebook to practice behaviors that align with their mothering identity and meet broader societal expectations, or in other words, to “do motherhood.” Given that Facebook use may undermine well-being, it is important to understand the individual differences underlying new mothers’ experiences with Facebook during the stressful first months of parenthood. Using survey data from a sample of 127 new mothers with Facebook accounts residing in the U.S. Midwest, we addressed two key questions: (a) Are individual differences in new mothers’ psychological characteristics associated with their use and experiences of Facebook? and (b) Are new mothers’ psychological characteristics associated with greater risk for depressive symptoms via their use and experiences of Facebook? Regression analyses revealed that mothers who were more concerned with external validation of their identities as mothers and those who believed that society holds them to excessively high standards for parenting engaged in more frequent Facebook activity and also reported stronger emotional reactions to Facebook commentary. Moreover, mothers who were more concerned with external validation were more likely to have featured their child in their Facebook profile picture. Mediation analyses indicated that mothers who were more prone to seeking external validation for their mothering identity and perfectionistic about parenting experienced increases in depressive symptoms indirectly via greater Facebook activity.
