The concept of voluntary consent

Our primary focus is on analysis of the concept of voluntariness, with a secondary focus on the implications of our analysis for the concept and the requirements of voluntary informed consent. We propose that two necessary and jointly sufficient conditions must be satisfied for an action to be voluntary: intentionality, and substantial freedom from controlling influences. We reject authenticity as a necessary condition of voluntary action, and we note that constraining situations may or may not undermine voluntariness, depending on the circumstances and the psychological capacities of agents. We compare and evaluate several accounts of voluntariness and argue that our view, unlike other treatments in bioethics, is not a value-laden theory. We also discuss the empirical assessment of individuals' perceptions of the degrees of noncontrol and self-control. We propose use of a particular Decision Making Control Instrument. Empirical research using this instrument can provide data that will help establish appropriate policies and procedures for obtaining voluntary consent to research.     

Lateralized repetition priming for familiar faces: Evidence for asymmetric interhemispheric cooperation

Repetition priming refers to facilitated recognition of stimuli that have been seen previously. Although a great deal of work has examined the properties of repetition priming for familiar faces, little has examined the neuroanatomical basis of the effect. Two experiments are presented in this paper that combine the repetition priming paradigm with a divided visual field methodology to examine lateralized recognition of familiar faces. In the first experiment participants were presented with prime faces unilaterally to each visual field and target faces foveally. A significant priming effect was found for prime faces presented to the right hemisphere, but not for prime faces presented to the left hemisphere. In Experiment 2, prime and target faces were presented unilaterally, either to the same visual field or to the opposite visual field (i.e., either within hemisphere or across hemispheres). A significant priming effect was found for the within right hemisphere condition, but not for the within left hemisphere condition, replicating the findings of the first experiment. Priming was also found in both of the across hemispheres conditions, suggesting that interhemispheric cooperation occurs to aid recognition. Taken in combination these experiments provide two main findings. First, an asymmetric repetition priming effect was found, possibly as a result of asymmetric levels of activation following recognition of a prime face, with greater priming occurring within the right hemisphere. Second, there is evidence for asymmetric interhemispheric cooperation with transfer of information from the right hemisphere to the left hemisphere to facilitate recognition.     

Concordance Between Parent Reports of Children's Mental Health Services and Service Records: The Services Assessment for Children and Adolescents (SACA)

The concordance between parent reports of children's mental health services and medical and administrative service records were assessed in a field test of the Services Assessment for Children and Adolescents (SACA) interview instrument. Service use reports from primary caregivers, usually mothers, for their child's emotional or behavioral problems were compared against inpatient, outpatient, and school records in St. Louis, one of the pilot sites for the Multi-Site Study of Service Use, Need, Outcomes and Costs in Child and Adolescent Populations (UNOCCAP). A global any use service variable, comprised of inpatient, outpatient, and school reports, yielded an overall service use concordance kappa of .76 between parent reports and records. Parent reports of inpatient hospitalization services using the SACA yielded the highest agreement with medical records, with kappa statistics of 1.00 for use of any inpatient hospital care and for medication use. Parent reports of specific inpatient services concurred with medical records more moderately, yielding kappas from .50 to .66. Reports of any outpatient mental health services yielded variable rates of agreement, with kappas ranging from .67 for any use of outpatient care, to .66 for medication use, to negligible kappas for specific treatments. Parent reports of school services were weakly related to records for most services, except for moderate agreement (.48) on placement in special classrooms for emotional or behavioral problems. Family burden or impact discriminated more powerfully than other variables between respondents who concurred with records and those who did not.     

Mindfulness and trauma: implications for treatment

Mindfulness, originally a construct used in Eastern spiritual and philosophical traditions, has found new utility in psychotherapy practice. Mindfulness practice has been recently applied to treatments of several psychological and health related problems, and research is showing successful outcomes in psychological interventions incorporating mindfulness practices. Several schools of psychotherapy have theorized why mindfulness may be an effective intervention. One population which would theoretically be benefited by mindfulness practice in treatment consists of those individuals who have experienced traumatic events and are exhibiting post-traumatic stress disorder and/or related correlates of past trauma. The present paper gives a general review of the application of mindfulness to clinical psychology interventions. Additionally, we explain how mindfulness is applicable to our integrative behavioral approach to treating trauma and its sequelae. Specifically, this paper will (a) give a general overview of the conceptions and applications of mindfulness to psychology and psychotherapy and provide a brief account of the concepts origins in eastern traditions; (b) discuss the theoretical conceptualization of clinical problems that may relate to the long-term correlates of trauma; (c) describe how mindfulness, acceptance and the therapeutic relationship can address trauma symptoms and discuss a modified treatment approach for trauma survivors that incorporates mindfulness and acceptance practices into traditional exposure treatment.

A questionnaire to assess school social climate

A questionnaire to assess the school social climate (CECSCE) made from items of The California School Climate and Safety Survey is presented. The CECSCE displays a stable factorial Oblimin structure in two social climate factors: 1) relative to the school and 2) relative to the teaching staff. Both factors present a correlation that oscillates between 0.42 and 0.48; and they explain 54,2% and 45,6% of the variance, respectively. Its reliability test-retest is acceptable (r= 0.61) after 9 months. Both factors present gender differences in favour of girls. They also differentiate at the educational level, displaying in 2 masculine course higher means in both factors than in 3 masculine course. The second factor correlates positively with the factors that measure social competence in the Merrell School Social Behaviour Scales and negatively with those that measure antisocial and non adapted behaviour.

Bryant's Empathy Index for children and adolescents: psychometric properties in the Spanish language

The present study investigated the following issues: (1) the structure of Bryant's Empathy Index for children and adolescents in a Spanish sample of 408 boys and 424 girls (M age=14.4 yr.), and (2) sex differences, including effect sizes and internal consistency of the scale. A principal components factor analysis with oblimin rotation showed that 20 of the index's 22 items load on three robust factors, related to Feelings of Sadness, Understanding Feelings, and Tearful Reaction with regard to the emotions of others. The 3-factor structure obtained an adequate fit to the data in the confirmatory factor analysis. Coefficients alpha ranged between .72 and .78. The 3 factors accounted for 42% of variance. As expected, girls scored higher than boys. It was concluded that the Spanish version of Bryant's Empathy Index has an acceptable reliability and construct validity, making it useful for research.     

Mother-infant relationships in baboons (Papio hamadryas): predictors of differences and discontinuities in developmental pathways

This study uses hierarchical linear regression modeling to analyze sources of variation in the developmental pathways of mother-infant relationships and to search for behavioral discontinuities. The data come from 23 mother-infant dyads of baboons (Papio hamadryas), whose interactions were recorded longitudinally during the infants' 1st year of life. The infant's sex and the mother's age and reproductive experience accounted for part of the variation observed in the developmental pathways of 11 of 20 behavioral measures analyzed; however, some of them did so only in some periods but not in others. The authors proposed that this can reflect the occurrence of reorganizations or discontinuities in the mother-infant relationship that can be related to important life events such as the mother's resumption of sexual activity.     

Promoting and protecting youth mental health through evidence-based prevention and treatment

For decades, empirically tested youth interventions have prevented dysfunction by addressing risk and ameliorated dysfunction through treatment. The authors propose linking prevention and treatment within an integrated model. The model suggests a research agenda: Identify effective programs for a broadened array of problems and disorders, examine ethnicity and culture in relation to intervention adoption and impact, clarify conditions under which programs do and do not work, identify change mechanisms that account for effects, test interventions in real-world contexts, and make tested interventions accessible and effective in community and practice settings. Connecting the science and practice of prevention and treatment will be good for science, for practice, and for children, adolescents, and their families.     

ERP and behavioral evidence of individual differences in metaphor comprehension

In two experiments, we examined individual differences in metaphor processing. In Experiment 1, the subjects judged the literal truth of literal, metaphorical, and scrambled sentences. Overall, metaphors were more difficult to judge as false, in comparison with scrambled controls, suggesting that the metaphorical meaning was being processed automatically. However, there were individual differences in that high-IQ subjects showed more interference. These effects were reflected in ERP amplitude differences at the onset of N400 and after the response. In Experiment 2, the subjects completed IQ tests and a series of working memory tests and then rated and interpreted the same set of metaphors. The results showed that IQ was correlated with working memory capacity and that low-IQ subjects had similar ratings but poorer quality interpretations than did high-IQ subjects. The results were most consistent with a constraint satisfaction approach to metaphor comprehension.
