Temporal integration and vibrotactile backward masking

Subjects were presented with vibrotactile target patterns to their left index fingertips. The target patterns varied in the number of line segments that they contained and were presented in the presence or absence of a backward-masking stimulus. The stimulus onset asynchrony (SOA) between the target and masker was varied. In an identification task, subjects' errors indicated that the effect of the masker at brief SOAs was to increase the perceived number of line segments in the target. This effect diminished with increasing SOA, and at the longest SOAs subjects confused targets with patterns containing the same number of line segments but varying in how the line segments were related. In an estimation task, the effect of the masker was to increase the number of line segments estimated to be contained in the target pattern. The effect of the masker at brief SOAs is discussed in terms of an integration theory of vibrotactile backward masking. At longer SOAs, the results suggest that the masker may interfere with the extraction of relational information in the target pattern.     

Mediation in custody disputes

This article summarizes the results of an evaluation of mediation services in three court-based programs. Among the issues considered are client evaluations of the mediation experience and their assessments of immediate and long-term effects. Two comparison groups are utilized: parents who contested custody without the offer of court-based mediation and parents who divorced but did not contest custody. Results of the research indicate that mediation provides a valuable compliment to the existing domestic relations court processes. Mediation enjoys high user satisfaction and helps promote compliance with the agreement, a sense of equity, and continued cooperation. Thus, while the expectations of the process should not be overstated, it appears that even a brief mediation with a troubled population can produce modest but positive benefits.     

The effects of progressive relaxation on stress and diabetic control

Four insulin-requiring diabetic Ss were followed in single-S designs to measure the impact of progressive muscle relaxation training on blood glucose and stress levels. Measures of blood glucose, stress, activity and caloric intake were taken four times a day, along with a daily measure of anxiety. Two of the 4 Ss showed a significant decrease in blood glucose during treatment periods as compared to baseline measures. Similarly, 2 of the 4 Ss showed a significant decrease in stress levels during treatment. A multiple regression analysis revealed some significant relationships between blood glucose, stress, activity level and caloric intake. The results support previous studies that show relaxation techniques to be a viable aid in establishing greater diabetic control.     

Generalization and maintenance of the reduction of self-injurious behavior maintained by two types of reinforcement

The self-injurious forehead-gouging behavior that had resulted in blindness for a profoundly retarded 27-yr-old male was successfully treated using a combination of differential reinforcement of incompatible behavior during unstructured situations and prevention of escape during compliance situations. After self-injurious behavior was reduced to a low frequency, a reduction of his daily dose of chloral hydrate was accompanied by a large increase in self-injury, but the behavior gradually returned to its previous low level. A large increase in self-injury also occurred following transfer to another living unit, but the behavior again decreased to a low frequency. Treatment gains were maintained following transfer to another residential facility with follow-up observations occurring at 1, 2, 8, 15, 22, 27 and 35 months. The multiple determination of self-injurious behavior in this one S highlights the behavioral complexity of some of these behaviors.     

A comparison of MMPI profiles of heroin addicts based on multiple methods of classification

MMPI profiles of 442 male narcotic addicts in a drug treatment program were classified according to one of three methods: (a) highest 2-point code, (b) cluster analysis, and (c) concordance with common actuarial rules of profile fit. Profiles were then compared with those previously reported in the research literature. While each method resulted in slightly different perspectives, each reported modal profiles analogous to the 49'/94', 42'/24', and 48'/84' profiles. A frequency table of 33 different profiles by rates per thousand were presented as prototypal base rates for future comparison.     

Effects of family therapy for substance abuse: A systematic review of recent research

One of the most serious psychosocial problems worldwide is substance abuse because of its repercussions not only on the physical and psychological health of the abuser but also on their relational functioning. Among the well-established therapeutic approaches for the treatment of substance abuse is family therapy, which, in addition to influencing personal variables, promotes changes in family dynamics. The main objective of this study is to review the scientific literature published from 2010 to the present on the efficacy and effectiveness shown by family-based treatment approaches for substance use problems both in adolescent and adult samples. In addition, the effect on secondary variables such as family functioning and behavioral problems is evaluated. The empirical evidence accumulated in the last decade and reviewed in the present study indicates that the incorporation of family members in the treatment of substance abuse produces benefits by diminishing consumption and improving family functioning. Limitations of this study and of the research reviewed are discussed and directions for future research are provided.     

Mathematical Practice,Fictionalism and Social Ontology

From the perspective of mathematical practice, I examine positions claiming that mathematical objects are introduced by human agents. I consider in particular mathematical fictionalism and a recent position on social ontology formulated by Cole (2013, 2015). These positions are able to solve some of the challenges that non-realist positions face. I argue, however, that mathematical entities have features other than fictional characters and social institutions. I emphasise that the way mathematical objects are introduced is different and point to the multifaceted role that relations and interconnections play in this context. Finally, I argue that mathematical entities can be considered to be pragmatically real.

     

Differences in the importance of romantic structures among transgender and cisgender adults during the COVID-19 pandemic

The stressors of the global COVID-19 pandemic have led to an increased need for support. For adults, romantic relationships often represent an environment of emotional support and stability; as such, attitudes toward—and particularly the importance of—romantic relationships may have shifted as a result of the pandemic. The present cross-sectional study explores how U.S. transgender (n = 99) and cisgender people (n = 1886) report whether they have perceived a change in their feelings about the importance of long-term romantic structures (i.e., committed relationships, monogamy, cohabiting with a romantic partner, and marriage) as a result of the COVID-19 pandemic. Results found that transgender people reported a more positive perceived change in importance placed on all four romantic items relative to cisgender people. Different forms of stress (e.g., social, financial, health) associated with the COVID-19 pandemic may have contributed to an increased need, and subsequent desire, for social connection and support in the form of romantic relationships among transgender individuals to a greater extent than cisgender individuals, perhaps in part due to the additional layers of stress transgender people must navigate. Results are discussed through the lens of the minority stress framework.
