‘Faultless’ ignorance: Strengths and limitations of epistemic definitions of confabulation

There is no satisfactory account for the general phenomenon of confabulation, for the following reasons: (1) confabulation occurs in a number of pathological and non-pathological conditions; (2) impairments giving rise to confabulation are likely to have different neural bases; and (3) there is no unique theory explaining the aetiology of confabulations. An epistemic approach to defining confabulation could solve all of these issues, by focusing on the surface features of the phenomenon. However, existing epistemic accounts are unable to offer sufficient conditions for confabulation and tend to emphasise only its epistemic disadvantages. In this paper, we argue that a satisfactory epistemic account of confabulation should also acknowledge those features which are (potentially) epistemically advantageous. For example, confabulation may allow subjects to exercise some control over their own cognitive life which is instrumental to the construction or preservation of their sense of self.     

Striatal outcome processing in healthy aging

Functional MRI of young adults has implicated the striatum in the processing of rewarding and punishing events. To date, only two published experiments (Samanez-Larkin et al., 2007; Schott et al., 2007) have explored similar phenomena in older adults, with both studies emphasizing the anticipation of monetary outcomes. To better understand older participants’ striatal responses to delivered outcomes, we engaged 20 older adults and 13 younger adults in a card-guessing task that rewarded correct guesses with monetary gain and punished incorrect guesses with monetary loss. Overall, the older adults retained most of the typical features of the striatal response, so that activity in the caudate head showed reliable differentiation between rewards and punishments during the 6- to 9-sec postoutcome window. Comparison of the older and younger adults also pointed to some potential aging effects on outcome activity, including reductions in the magnitude and extent of striatal activation, and a trend for the older adults to show a decreased early punishment response. In sum, our data suggest that the signaling of outcome valence remains relatively stable into late adulthood, although more research is needed to understand some subtle changes that might occur across the life span.     

Automaticity for numerical magnitude of two-digit Arabic numbers in children

This paper examines the automatic processing of the numerical magnitude of two-digit Arabic numbers using a Stroop-like task in school-aged children. Second, third, and fourth graders performed physical size judgments on pairs of two-digit numbers varying on both physical and numerical dimensions. To investigate the importance of synchrony between the speed of processing of the numerical magnitude and the physical dimensions on the size congruity effect (SCE), we used masked priming: numerical magnitude was subliminally primed in half of the trials, while neutral priming was used in the other half. The results indicate a SCE in physical judgments, providing the evidence of automatic access to the magnitude of two-digit numbers in children. This effect was modulated by the priming type, as a SCE only appeared when the numerical magnitude was primed. This suggests that young children needed a relative synchronization of numerical and physical dimensions to access the magnitude of two-digit numbers automatically.     

The cocktail party problem: what is it? How can it be solved? And why should animal behaviorists study it?

Animals often use acoustic signals to communicate in groups or social aggregations in which multiple individuals signal within a receiver's hearing range. Consequently, receivers face challenges related to acoustic interference and auditory masking that are not unlike the human cocktail party problem, which refers to the problem of perceiving speech in noisy social settings. Understanding the sensory solutions to the cocktail party problem has been a goal of research on human hearing and speech communication for several decades. Despite a general interest in acoustic signaling in groups, animal behaviorists have devoted comparatively less attention toward understanding how animals solve problems equivalent to the human cocktail party problem. After illustrating how humans and nonhuman animals experience and overcome similar perceptual challenges in cocktail-party-like social environments, this article reviews previous psychophysical and physiological studies of humans and nonhuman animals to describe how the cocktail party problem can be solved. This review also outlines several basic and applied benefits that could result from studies of the cocktail party problem in the context of animal acoustic communication.     

The Substance Abuse Counseling Needs of Women in the Criminal Justice System: A Needs Assessment Approach

The authors assessed the substance abuse counseling needs of women in the criminal justice system using interviews (n = 304) and surveys (n = 1,170). On the basis of the results, the authors call for gender‐specific treatment as well as family‐oriented support for women who are mothers.     

Female religious leadership in Switzerland: norms,power, and money

Women’s access to positions of leadership in religions is a highly contested issue in Western societies, both inside religions themselves and in societal discussions of religion. Reliable data on actual female leadership are, however, scarce, especially in European countries and regarding minority religions. This article describes and explains statistically the normative openness of congregations to female leadership as well as the actual existence, position, and financial remuneration of female leaders across the whole range of religious traditions in Switzerland. The study is based on data from the representative National Congregations Study of 2008/2009. Our results show that, despite considerable normative openness, female spiritual and administrative leadership remains scarce in most religious traditions. The highest percentage of female spiritual leaders can be found in the milieu of alternative spirituality, followed by the Reformed congregations. A generally high percentage of female leadership can be found on administrative boards. It is only leadership positions in certain Christian traditions (Reformed, Catholic, Evangelical-classical) that are normally remunerated for women; many other traditions do not have female leadership or, as in the case of the milieu of alternative spirituality, such leadership positions are not remunerated.     

Effectiveness of a trauma/grief-focused group intervention: a qualitative study with war-exposed Bosnian adolescents

The effectiveness and impacts of a school-based, trauma/grief-focused group treatment program for war-exposed youth in Bosnia and Herzegovina were investigated using semistructured focus groups, conducted separately for students and their school counselor group leaders. Overall, students' and leaders' evaluations of the groups were generally positive. General themes of outcomes and impacts perceived by students and group leaders include: acquisition of coping skills and attitudes, willingness to advocate for peers, improved interpersonal relationships, negative impacts, general positive impacts, impacts in the schools, impacts on the group and logistics of the program, and broader impacts on the perception of mental health in the community. The broad positive impacts of this program suggest that trauma/grief-focused group treatment intervention programs targeting trauma-exposed youth may be effective on multiple levels with war-exposed youth and their communities.     

Robust dimensions of anxiety sensitivity: development and initial validation of the Anxiety Sensitivity Index-3

Accumulating evidence suggests that anxiety sensitivity (fear of arousal-related sensations) plays an important role in many clinical conditions, particularly anxiety disorders. Research has increasingly focused on how the basic dimensions of anxiety sensitivity are related to various forms of psychopathology. Such work has been hampered because the original measure--the Anxiety Sensitivity Index (ASI)--was not designed to be multidimensional. Subsequently developed multidimensional measures have unstable factor structures or measure only a subset of the most widely replicated factors. Therefore, the authors developed, via factor analysis of responses from U.S. and Canadian nonclinical participants (n=2,361), an 18-item measure, the ASI-3, which assesses the 3 factors best replicated in previous research: Physical, Cognitive, and Social Concerns. Factorial validity of the ASI-3 was supported by confirmatory factor analyses of 6 replication samples, including nonclinical samples from the United States and Canada, France, Mexico, the Netherlands, and Spain (n=4,494) and a clinical sample from the United States and Canada (n=390). The ASI-3 displayed generally good performance on other indices of reliability and validity, along with evidence of improved psychometric properties over the original ASI.
