“At least one” problem with “some” formal reasoning paradigms

In formal reasoning, the quantifier "some" means "at least one and possibly all." In contrast, reasoners often pragmatically interpret "some" to mean "some, but not all" on both immediate-inference and Euler circle tasks. It is still unclear whether pragmatic interpretations can explain the high rates of errors normally observed on syllogistic reasoning tasks. To address this issue, we presented participants (reasoners) in the present experiments either standard quantifiers or clarified quantifiers designed to precisely articulate the quantifiers' logical interpretations. In Experiment 1, reasoners made significantly more logical responses and significantly fewer pragmatic responses on an immediate-inference task when presented with logically clarified as opposed to standard quantifiers. In Experiment 2, this finding was extended to a variant of the immediate-inference task in which reasoners were asked to deduce what followed from premises they were to assume to be false. In Experiment 3, we used a syllogistic reasoning task and observed that logically clarified premises reduced pragmatic and increased logical responses relative to standard ones, providing strong evidence that pragmatic responses can explain some aspects of the errors made in the syllogistic reasoning task. These findings suggest that standard quantifiers should be replaced with logically clarified quantifiers in teaching and in future research.     

Building Capacity of State Adolescent Pregnancy Prevention Coalitions to Implement Science-Based Approaches

A central question in adolescent reproductive health circles is how to effectively disseminate research to practitioners in a way that supports them in using the most scientifically sound and effective programming. In 2002, the Division of Reproductive Health at the Centers for Disease Control and Prevention (CDC) tackled this question by funding three national-level and five state-level organizations focused on adolescent pregnancy prevention to promote the use of science-based programs and approaches. Healthy Teen Network (HTN) and Education, Training and Research Associates (ETR), two national organizations, have partnered under this CDC funding to implement an effective model for capacity building. This paper provides an overview of the approaches used by HTN and ETR in capacity building using a seven-step process. We describe how we modified the Interactive Systems Framework for Dissemination and Implementation (ISF) for science-based innovations to apply to capacity-building for adolescent reproductive health (ARH) programs, and how we developed relevant, sustainable training and technical support. We conclude by reviewing some of the results of this training, and discuss the future work that will likely continue to advance the science behind effective dissemination of ARH research to practice.     

Air pollution, cognitive deficits and brain abnormalities: a pilot study with children and dogs

Exposure to air pollution is associated with neuroinflammation in healthy children and dogs in Mexico City. Comparative studies were carried out in healthy children and young dogs similarly exposed to ambient pollution in Mexico City. Children from Mexico City (n: 55) and a low polluted city (n:18) underwent psychometric testing and brain magnetic resonance imaging MRI. Seven healthy young dogs with similar exposure to Mexico City air pollution had brain MRI, measurement of mRNA abundance of two inflammatory genes cyclooxygenase-2, and interleukin 1 beta in target brain areas, and histopathological evaluation of brain tissue. Children with no known risk factors for neurological or cognitive disorders residing in a polluted urban environment exhibited significant deficits in a combination of fluid and crystallized cognition tasks. Fifty-six percent of Mexico City children tested showed prefrontal white matter hyperintense lesions and similar lesions were observed in dogs (57%). Exposed dogs had frontal lesions with vascular subcortical pathology associated with neuroinflammation, enlarged Virchow-Robin spaces, gliosis, and ultrafine particulate matter deposition. Based on the MRI findings, the prefrontal cortex was a target anatomical region in Mexico City children and its damage could have contributed to their cognitive dysfunction. The present work presents a groundbreaking, interdisciplinary methodology for addressing relationships between environmental pollution, structural brain alterations by MRI, and cognitive deficits/delays in healthy children.     

Training and Mentoring of Chemists: A Study of Gender Disparity

This study was conducted to compare women’s and men’s retrospective perceptions of the mentoring they received during their training and career development in chemistry. Participants were 455 graduates (135 women) who received doctoral degrees from 11 top US chemistry programs over a 5-year period (1988–1992). In 2003, graduates completed surveys of undergraduate, graduate, post-doctoral, and initial employment experiences. In line with Social Cognitive Career Theory (Lent et al., Journal of Vocational Behavior 45:79–122, 1994), which posits that perceptions of barriers can affect career decisions, results suggest that women perceived that they received less mentoring than men at the undergraduate, graduate, and post-doctoral levels of training, likely related to gender differences in eventual career success. Possible interventions at the individual and institutional levels are discussed.     

Explaining contradictory relations between risk perception and risk taking

Different studies have documented opposite relations between perceived risk and behavior. The present study tested a theoretical explanation that reconciles these conflicting results. Adolescents (N= 596) completed alternative measures of risk perception that differed in cue specificity and response format. As predicted by fuzzy-trace theory, measures that emphasized verbatim retrieval and quantitative processing produced positive correlations between perceived risk and risky behavior; risk perceptions reflected the extent to which adolescents engaged in risky behavior. In contrast, measures that assessed global, gist-based judgments of risk produced negative correlations; higher risk perceptions were associated with less risk taking, a protective rather than reflective relation. Endorsement of simple values and principles provided the greatest protection against risk taking. Results support a dual-processes interpretation of the relation between risk perception and risk taking according to which observed relations depend on whether the cues in questions trigger verbatim or gist processing.     

Social sharing of emotional experiences in Asian American and European American women

The present study investigated the relationships among ethnicity and social sharing of traumatic experiences in a sample of 88 East Asian and 88 European American women. Participants were asked to write about a traumatic experience for twenty minutes and then to rate how upsetting the experience was, how often they thought about it, how often and to whom they had previously disclosed the experience, as well as the perceived appropriateness of sharing the experience with different target audiences, e.g., friends and family members. The results indicated that Asian Americans reported speaking to others less frequently about the traumatic event and sharing it with fewer individuals, and tended to be more likely to share the event with friends than with family members when compared to European Americans. Asian Americans also reported thinking about the upsetting event less frequently than European Americans even though both groups reported that the events were equally upsetting. The more upsetting events were, the more often they were shared in the European American group, but there was no relationship between how upsetting events were and the degree to which they were shared in the Asian American group.     

Parent Motivation to Participate in Treatment: Assessment and Prediction of Subsequent Participation

Treatment motivation is required for virtually all psychosocial treatments because clients must participate actively in the treatment process. In child and family treatments, it is the parent who must be motivated to manage treatment participation; however, no measures are currently available for evaluating parent motivation for treatment. The authors developed and evaluated a brief rating scale, the Parent Motivation Inventory (PMI), to measure parent motivation to participate in treatment. Results supported a uni-dimensional measure with strong internal consistency and test-retest reliability. Increases in parent motivation predicted the perception of fewer barriers to treatment participation, which was significantly associated with greater treatment attendance. The PMI provides a reliable and valid method of assessing parents’ motivation to participate in treatment and has implications for the prediction and potential modification of barriers to treatment and treatment participation.     

Treatment of co-occurring child maltreatment and substance abuse

Despite high prevalence and severe negative consequences of child maltreatment (e.g., Brown, G. R., & Anderson, B., (1991). Psychiatric morbidity in adult inpatients with childhood histories of sexual and physical abuse. American Journal of Psychiatry, 148, 55–61; Jaudes, P. K., Ekwo, E., & Van Voorhis, J.V., (1995). Association of drug abuse and child abuse. Child Abuse and Neglect, 19, 1065–1075; Murphy, J. M., Jellinek, M., Quinn, D., Smith, G., & Goshkom, M., (1991). Substance abuse and serious child mistreatment: Prevalence, risk, and outcome in a court sample. Child Abuse and Neglect, 15, 197—211), the treatment of perpetrators and victims of child abuse and neglect remains grossly understudied (Behl, L. E., Conyngham, H. A., & May, P. F., (2003). Trends in child maltreatment literature. Child Abuse and Neglect, 27, 215–229). More than half of parentes founded for the abuse and neglect of their children have evidenced drug abuse, yet no treatments have been validated that concurrently address these problems. The reciprocal interaction between substance abuse and child maltreatment supports the need to concurrently treat these problems. This article illustrates the relationship between child maltreatment and parental substance abuse and proposes a behavioral model to explain the reciprocal influence of drug abuse and child maltreatment. A behavioral treatment plan that is designed to concurrently address drug abuse and child abuse is proposed and suggestions are made for future directions in this area.     

Remembering helpers and hinderers depends on behavioral intentions of the agent and psychopathic characteristics of the observer

Individual differences in proneness towards granting benefits (i.e., helping) or imposing costs (i.e., hindering) may have led to processes that detect and remember people who are prone to help or hinder. We examined two factors that might influence such memory: the intentionality of the acts and individual differences in psychopathy characteristics. Participants viewed several videos of computer-animated agents that helped or hindered another agent, either intentionally or unintentionally. Afterward, participants had better memory for agents that acted intentionally. Additionally, participants with more psychopathic tendencies had enhanced memory for helpers, suggesting that certain individual characteristics might result in heightened memory for people who are prone to granting benefits.
