Illuminating the dark side of creative expression: assimilation needs and the consequences of creative action following mortality salience

Previous research indicates that mortality salience and creative behavior combine to increase feelings of guilt, presumably over the disruption to social connection elicited by the call for innovative expression. The present studies examined whether satiating assimilation motives by highlighting conformity to others reduces this effect (Study 1) and facilitates positive psychological engagement (Study 2). Study 1 used a 2 (conformity vs. neutral feedback)x2 (mortality salience vs. control)x2 (creative task vs. noncreative task) design and had participants complete a self-report measure of guilt. Study 2 used a 2 (mortality salience vs. control)x2 (other goal task vs. self-goal task) design, and after a creativity exercise, had participants complete measures of positive mood, vitality, and creative problem solving. Results indicated attending to assimilation needs reduced the elevated guilt that follows the juxtaposition of mortality salience and creative behavior and also increased a sense of positive engagement. Implications are briefly discussed.     

Is synaesthesia an X-linked dominant trait with lethality in males?

In previous research the inheritance patterns of synaesthesia (eg experiencing colours from graphemes) has been studied and it was concluded that synaesthesia is most likely to be the outcome of a single gene passed on the X chromosome in a dominant fashion. In addition, it has been reported that the female-male ratio of synaesthetes is as high as 6:1 and the families of synaesthetes contain more female than male members. This raises the possibility that the gene may be associated with lethality in males. In this study we replicate and extend previous research by investigating the female-male ratio and inheritance patterns in a large sample of synaesthetic families (N = 85). We were able to verify the authenticity of grapheme-colour associates in at least one proband from each family using internal consistency. As before, our results show a female-male bias and are broadly consistent with an X-linked dominant mode of inheritance. However, there was no evidence of male lethality (eg synaesthetes are just as likely to give birth to sons as to daughters). Moreover, our female-male ratio of synaesthetes within families was 2:1--considerably lower than previous estimates. We speculate that men may be more reluctant to disclose synaesthesia than women (indeed, our female-male ratio based on self-referral was 3.7: 1). Finally, we discuss how the genotype may give rise to the phenotype in terms of changes in synaptogenesis or plasticity extending into childhood, to be subsequently shaped by the environment.     

Validation of the Beck Depression Inventory-II in a low-income African American sample of medical outpatients

The psychometric properties of the Beck Depression Inventory-II (BDI-II) are well established with primarily Caucasian samples. However, little is known about its reliability and validity with minority groups. This study evaluated the psychometric properties of the BDI-II in a sample of low-income African American medical outpatients (N=220). Reliability was demonstrated with high internal consistency (.90) and good item-total intercorrelations. Criterion-related validity was demonstrated. A confirmatory factor analysis supported a hierarchical factor structure in which the BDI-II reflected 2 first-order factors (Cognitive and Somatic) that in turn reflected a second-order factor (Depression). These results are consistent with previous findings and thus support the use of the BDI-II in assessing depressive symptoms for African American patients in a medical setting.     

ON THE REINFORCING EFFECTS OF THE CONTENT OF VERBAL ATTENTION

During a functional analysis, a boy with autism and oppositional defiant disorder displayed destructive behavior that was maintained by attention in the form of verbal reprimands (e.g., “Don't hit me”). In a second analysis, contingent verbal reprimands produced higher rates of the behavior than contingent statements that were unrelated to the target response (e.g., “It is sunny today”), suggesting that some forms of attention were more reinforcing than others. A treatment based on these analyses reduced the behavior to near-zero levels.     

Maintaining placement for troubled and disruptive adolescents in voluntary residential care: The role of reduced youth-to-staff ratio

We evaluated a program to protect the placements of 23 highly troublesome youth in voluntary residential care by reducing youth-to-staff ratios. Specifically, the youth were moved from regular program homes (with eight youth) to reduced ratio homes (with only four youth) instead of being terminated from the program. We provide evidence supporting the assertion that youth in the study sample were highly troublesome and at high risk for program failure and more restrictive placements. Placement in the reduced ratio homes protected the trouble youths' placement, resulting in an additional mean length of stay of 950 day without an increase in program restrictiveness. Further, the reduced ratio homes increased the chances of success in the program for the study sample to a level equivalent to that for the much less troubled comparison sample. Cost estimates are also provided.     

Geometry and generality in Frege's philosophy of arithmetic

This paper develops some respects in which the philosophy of mathematics can fruitfully be informed by mathematical practice, through examining Frege'sGrundlagen in its historical setting. The first sections of the paper are devoted to elaborating some aspects of nineteenth century mathematics which informed Frege's early work. (These events are of considerable philosophical significance even apart from the connection with Frege.) In the middle sections, some minor themes ofGrundlagen are developed: the relationship Frege envisions between arithmetic and geometry and the way in which the study of reasoning is to illuminate this. In the final section, it is argued that the sorts of issues Frege attempted to address concerning the character of mathematical reasoning are still in need of a satisfying answer.I am indebted to many people for helpful conversations and comments on this paper, notably Stephen Glaister, Phil Kremer, Madeline Larson, John McDowell, Jim Conant, Charles Chihara, William Craig, Jan Alnes, Joan Weiner, Leon Henkin, Paul Benacerraf, Juliet Floyd, Bill Demopoulos, Jose Ferreiros, Tom Hawkins, Gideon Rosen. Two superb papers on Frege — Bill Demopoulos' (1994) and Mark Wilson (1992) played a significant role in the early stages of composition.
