An intelligent PET interface for environmental control and data acquisition and analysis

An interface, controlled by a Z-80 central processor, that plugs into the PET microcomputer’s IEEE-488 port is described. This interface is capable of controlling 48 separate 28-V dc output signals, six of which are high current. Sixteen inputs (switch closures) can be accepted by the interface. Data tagged with real-time information are output automatically to cassette tape in PET format. This PET interface system is designed to accommodate a single experimental station.     

Meaning for Radical Contextualists: Travis and Gadamer on Why Words Matter

Charles Travis and Hans‐Georg Gadamer both affirm radical contextualism, the view that natural language is ineliminably context‐sensitive. However, they offer different accounts of the role linguistic meaning plays in determining the contents of utterances. I discuss the differences between Travis's and Gadamer's views of meaning and offer an argument in favour of the latter. I argue that Travis's view assumes a principled distinction between literal and figurative speech that is at odds with his wider contextualist commitments. By contrast, Gadamer's view, on which meaning is ‘fundamentally metaphorical,’ makes no such assumption and thus avoids the difficulty.     

Introduction: Belief as Cultural Performance

Abstract

Although the concept of belief has become a focus of critical discussion in other disciplines, sociologists of religion have tended to assume that belief is a universal phenomenon, structured around cognitive propositions which can be made explicit in the context of research surveys and interviews The articles in this special issue of the Journal of Contemporary Religion explore belief in the lives of young people in different religious, cultural, and national contexts to suggest more complex ways in which belief might be conceptualised and researched. While the ‘authenticity’ of belief is a significant value for young people across these cases, the authors show how belief can, in different contexts, be a marker of identity, an expression of socially significant relationships or an organising centre for the lives of individuals and groups. Belief can also be understood as the performance of embodied practices shaped by one’s spatial and cultural environment. In this wider context, training young people in propositional forms of belief is shown to be a particular kind of religious project, which can be unstable and have unintended consequences.     

Heightened sensitivity to facial expressions of emotion in borderline personality disorder

Individuals with borderline personality disorder (BPD) have been hypothesized to exhibit significant problems associated with emotional sensitivity. The current study examined emotional sensitivity (i.e., low threshold for recognition of emotional stimuli) in BPD by comparing 20 individuals with BPD and 20 normal controls on their accuracy in identifying emotional expressions. Results demonstrated that, as facial expressions morphed from neutral to maximum intensity, participants with BPD correctly identified facial affect at an earlier stage than did healthy controls. Participants with BPD were more sensitive than healthy controls in identifying emotional expressions in general, regardless of valence. These findings could not be explained by participants with BPD responding faster with more errors. Overall, results appear to support the contention that heightened emotional sensitivity may be a core feature of BPD.     

Resource slack and propensity to discount delayed investments of time versus money

The authors demonstrate that people discount delayed outcomes as a result of perceived changes over time in supplies of slack. Slack is the perceived surplus of a given resource available to complete a focal task. The present research shows that, in general, people expect slack for time to be greater in the future than in the present. Typically, this expectation of growth of slack in the future is more pronounced for time than for money. In 7 experiments, the authors demonstrate that systematic temporal shifts of perceived slack determine the extent and the pattern of delay discounting, including hyperbolic discounting. They use this framework to explain differential propensity to delay investments and receipts of time and money.     

Therapeutic techniques vs therapeutic relationships in child behavior therapy

The parents of 56 children who had received behavior therapy rated a number of variables, including the degree to which they viewed the therapeutic relationship versus the specific techniques used in treatment as important, the extent to which the child improved in therapy, and the child's present functioning. Therapists also provided ratings of clinical improvement. Even though parents gave the highest ratings for the importance of the relationship in therapy, the correlation between technique and clinical outcome was statistically significant while the correlations between the relationship and outcome was not. These statistical associations also held when therapists rated improvement. Also, therapists saw greater improvement in children than did the parents. Over-all, the results support the view that the relationship and techniques are interwoven and are both perceived as important factors in treatment.
