Making the Technological Trustworthy:

Joseph C. Pitt, based on his understanding of trust and of technology, makes the provocative argument that trusting technology is actually a matter of trusting people. I agree with Pitt’s conclusion but differ with him on the nature of trust. I contend, nonetheless, that my understanding of trust actually reinforces Pitt’s characterization of technology as “humanity at work.”

What aspects of face processing are impaired in developmental prosopagnosia?

Developmental prosopagnosia (DP) is a severe impairment in identifying faces that is present from early in life and that occurs despite no apparent brain damage and intact visual and intellectual function. Here, we investigated what aspects of face processing are impaired/spared in developmental prosopagnosia by examining a relatively large group of individuals with DP (n = 8) using an extensive battery of well-established tasks. The tasks included measures of sensitivity to global motion and to global form, detection that a stimulus is a face, determination of its sex, holistic face processing, processing of face identity based on features, contour, and the spacing of features, and judgments of attractiveness. The DP cases showed normal sensitivity to global motion and global form and performed normally on our tests of face detection and holistic processing. On the other tasks, many DP cases were impaired but there was no systematic pattern. At least half showed deficits in processing of facial identity based on either the outer contour or spacing of the internal features, and/or on judgments of attractiveness. Three of the eight were impaired in processing facial identify based on the shape of internal features. The results show that DP is a heterogeneous condition and that impairment in recognizing faces cannot be predicted by poor performance on any one measure of face processing.     

The robustness of estimates of total indirect effects in covariance structure models estimated by maximum

The large sample distribution of total indirect effects in covariance structure models in well known. Using Monte Carlo methods, this study examines the applicability of the large sample theory to maximum likelihood estimates oftotal indirect effects in sample sizes of 50, 100, 200, 400, and 800. Two models are studied. Model 1 is a recursive model with observable variables and Model 2 is a nonrecursive model with latent variables. For the large sample theory to apply, the results suggest that sample szes of 200 or more and 400 or more are required for models such as Model 1 and Model 2, respectively.For helpful comments on a previous draft of this paper, we are grateful to Gerhard Arminger, Clifford C. Clogg, and several anonymous reviewers.     

On the significance of conditional probabilities

The orthodoxy that conditional probabilities reflect what are for a subject evidential bearings is seconded. This significance suggests that there should be principles equating rationally revised probabilities on new information with probabilities reached by conditionalizing on this information. Several principles, two of which are endorsed, are considered. A book is made against a violator of these, and it is argued that there must be something wrong with a person against whom such books can be made. Appendices comment on Popper-functions, elaborate on bets and odds, and relate dutch books and strategies to conditions of inconsistency (Ramsey's idea) and imperfection.This paper corrects and elaborates two-fold Conditional Probabilities, Conditionalization, and Dutch Books, PSA 1990: Proceedings of the Biennial Meeting of the Philosophy of Science Association, Volume 1, edited by A. Fine, M. Forbes, and L. Wessels, East Lansing, Michigan, 1990.     

Microinfusion of the D1 receptor antagonist, SCH23390 into the IL but not the BLA impairs consolidation of extinction of auditory fear conditioning

In auditory fear conditioning, repeated presentation of the tone in the absence of the shock leads to extinction of the acquired fear response. Both the medial prefrontal cortex (mPFC) and the basolateral amygdala (BLA) are involved in extinction. Here we examined this involvement by antagonizing D1 receptors in both regions, in the rat. We microinfused the D1 receptor antagonist, SCH23390, into the infra-limbic part of the mPFC (IL) or BLA at different time points. SCH23390 mircoinfused into the IL either before extinction acquisition or following short extinction training resulted in impairment of extinction consolidation. Microinfusion of SCH23390 into the BLA, prior to acquisition of extinction caused impairment in acquisition of extinction without affecting extinction consolidation. This is supported by the results showing that microinfusion of SCH23390 into the BLA following a short-training session did not affect consolidation. These results further strengthen the role of mPFC in consolidation of extinction while highlighting the role of the D1 receptors in this process.     

Skills Practice in Dialectical Behavior Therapy for Suicidal Women Meeting Criteria for Borderline Personality Disorder

Dialectical Behavior Therapy (DBT) is an evidence-based practice for borderline personality disorder (BPD) and suicidal behavior that has been replicated with a variety of populations. Patients’ practice of behavioral skills taught in the group skills training component of DBT may be partly responsible for the positive treatment outcomes according to the skills deficit model of BPD that underlies DBT. This study was designed to examine the type and frequency of skills practiced by DBT patients. Participants were 49 women, who met criteria for BPD and current and chronic suicidal behavior, receiving 1 year of standard DBT as part of a clinical trial. Skills were recorded on the daily diary cards completed by participants each week and reviewed by their individual therapists. Results indicated that the majority of participants reported practicing skills most days throughout treatment. Crisis survival and mindfulness skills were practiced most frequently in our sample. Hierarchical linear modeling demonstrated that skills practice increased as a function of time in therapy. Directions for future research are discussed.
