Grounds and limits: Reichenbach and foundationalist epistemology

From 1929 onwards, C. I. Lewis defended the foundationalist claim that judgements of the form ‘x is probable’ only make sense if one assumes there to be a ground y that is certain (where x and y may be beliefs, propositions, or events). Without this assumption, Lewis argues, the probability of x could not be anything other than zero. Hans Reichenbach repeatedly contested Lewis’s idea, calling it “a remnant of rationalism”. The last move in this debate was a challenge by Lewis, defying Reichenbach to produce a regress of probability values that yields a number other than zero. Reichenbach never took up the challenge, but we will meet it on his behalf, as it were. By presenting a series converging to a limit, we demonstrate that x can have a definite and computable probability, even if its justification consists of an infinite number of steps. Next we show the invalidity of a recent riposte of foundationalists that this limit of the series can be the ground of justification. Finally we discuss the question where justification can come from if not from a ground.     

An evaluation and comparison of time-out procedures with and without release contingencies

A common recommendation for implementing time‐out procedures is to include a release contingency such that the individual is not allowed to leave time‐out until no problem behavior has occurred for a specific amount of time (e.g, 30 s). We compared a fixed‐duration time‐out procedure to a release contingency time‐out procedure with 4 young children (3‐ and 4‐year‐olds) using a reversal and multielement design. Results demonstrated that both time‐out procedures were effective at reducing problem behavior outside time‐out, problem behavior occurred in time‐out during both procedures, and problem behavior in time‐out was not predictive of problem behavior outside time‐out.     

THE INFLUENCE OF ANTECEDENTS AND CONSEQUENCES ON THE OCCURRENCE OF BIZARRE SPEECH IN INDIVIDUALS WITH DEMENTIA

We conducted a series of assessments to determine the differential effects of common antecedents and consequences that can influence the occurrence of bizarre speech in three women with moderate to severe dementia. First, a traditional functional analysis was conducted to assess the function of bizarre speech. After results revealed differentially higher levels of bizarre speech during control sessions, an antecedent analysis was conducted. During this second assessment, all consequences were held constant, and only the antecedents (i.e., open‐ended questions, yes/no questions, and comments) were altered. Bizarre speech was differentially higher when open‐ended questions were presented, replicating previous studies. The final assessment conducted was a modified functional analysis to further assess the effects of consequences on bizarre speech. More typical consequences were assessed, including two tests for a positive function (attention in the form of correction and attention in the form of following along) and two tests for a negative function (a break from one question and a break from all questions). Results consistently revealed that antecedents produced greater differentiation in responding than social consequences. These findings provide evidence that behavioral assessments may need to be modified to better capture the relevant environmental variables that influence problem behavior in individuals with dementia.

Reentry Women After Graduation

Reentry women (M age, 42.2 years) were compared with younger women (M age, 25.8 years) on a survey conducted 2 to 6 years after their graduation from college. A total of 451 graduates responded to questions about education and employment activities, job satisfaction, and leisure pursuits. Discriminant function analyses revealed clear-cut differences between the two age groups and also among the six age/marital groups (single, married, and formerly married). The great majority of these reentry women were found to be employed outside the home and to be earning significantly higher salaries than their younger counterparts. Of the six age/marital groups, both single and married reentry women rated themselves highest in job satisfaction; this greater satisfaction appeared to be based on feelings of accomplishment and autonomy.     

The Early Lives of Highly Creative Persons: The Influence of the Complex Family

Over the last 50 years, theoretical, speculative, and empirical scholarship has examined the influence of early family context on subsequent accomplishments in children of high ability. Building upon 40 years of creativity literature focusing on optimal experience, this exploratory study applied the Complex Family Framework in a systematic analysis of creative adults' recollections of their early family lives. The study identifies evidence of the interplay of Integration and Differentiation, a catalyst for individual optimal experience, in the families of 9 creative exemplars who have made significant contributions to contemporary culture. Five participants represented the Arts and Humanities, three the Social Sciences, and one the Physical Sciences. The study demonstrates the utility of the Complex Family Framework in understanding families' contributions to children's later creative achievement.     

Commentary on Paper by Danielle Knafo

The author discusses the importance of Knafo's rich paper on the often neglected subject of solitude but argues for a clearer demarcation of the multifarious states of aloneness, solitude, loneliness, and isolation. While solitude constitutes a state of plentitude, demonstrating an ability to be alone in the company of an Other, loneliness, in contrast, conjures up a sense of dread and despair, foreseeing no link to an Other. Hence, an artwork can fulfill radically different aspects of the various states of aloneness, it can be a product emerging out of a full sense of solitude, or it can function as a forceful shield against the unbearable sense of loneliness.     

A Screening Tool to Assess and Manage Behavioral Risk in the Postoperative Bariatric Surgery Patient: The WATCH

Bariatric surgery is increasingly recognized as a highly effective treatment for individuals who are severely obese. Amount of weight loss and resolution of comorbidities surpass those of nonsurgical approaches; however, suboptimal weight loss and weight regain are not uncommon. These outcomes, though not fully understood, are likely at least partially explained by failure to make long-term behavioral and/or cognitive changes. We are unaware of any established clinical tools to guide providers in assessing postoperative behaviors and identifying those who may require specialized treatment. The goal of this paper is to introduce a brief screening tool, The WATCH, to help clinicians assess and identify patients who may be at risk for poor or untoward outcomes post bariatric surgery. We first review the literature on postoperative outcomes, including weight loss, resolution of comorbidities, suboptimal outcomes, and development of problematic eating behaviors. We then provide an easily-recalled, five-item tool that assesses outcomes, and discuss patient responses that may necessitate further intervention or referral.     

Ritual Abuse-Torture Within Families/Groups

Case studies provide insights into identifying 10 violent thematic issues as components of a pattern of family/group ritual abuse-torture (RAT) victimization. Narratives from victimized women suggest that victimization generally begins in infancy or soon thereafter. A visual model of RAT displays the organization of the co-culture. Examples of the family/group gatherings known as “rituals and ceremonies” provide insights into how these gatherings are used to normalize pedophilic violence. Global activism afforded the first effort ever to track RAT and human trafficking. Recognizing RAT as an emerging form of non-state actor torture, discontinuing the use of language that sexualizes adult-child relationships, and promoting human rights education are suggested social solutions.
