Treating destructive behavior reinforced by increased caregiver compliance with the participant's mands

Functional analyses sometimes do not identify momentary fluctuations in the function of destructive behavior (Bowman, Fisher, Thompson, & Piazza, 1997). In such cases, individuals may mand for the reinforcer that is currently most preferred and display destructive behavior if that mand goes unreinforced. In this study, we conducted a mand analysis to test whether destructive behavior functioned as a precurrent response that increased reinforcement for the participant's mands. We then evaluated a treatment that matched this function of destructive behavior by providing differential or time-based reinforcement of participant mands in accordance with multiple or chained schedules with reinforcement-schedule thinning. Decreases in destructive behavior averaged 97.4% across cases. We discuss these results relative to the importance of matching treatments for destructive behavior to operant functions for both traditional and idiosyncratic functions of destructive behavior.     

The Significance of Contingency and Detours in Hans Blumenberg’s Philosophical Anthropology

Although time was a predominate theme in Continental philosophy for the first half of the twentieth century, philosophical attention has increasingly shifted to space. This paper contributes to the phenomenology of space through Hans Blumenberg’s philosophical anthropology. Blumenberg elucidates the significance of phenomenological distance for the contingent existence of humans. Spanning from the experience of early human ancestors to history and epistemology, Blumenberg’s work reveals how contingency pervades human existence. Blumenberg understands names, myths, rhetoric, and metaphors as cultural techniques that function as means of self-preservation by distancing an overwhelming and disorienting reality and managing the felt contingency of human existence. Developing upon Blumenberg’s insights into human contingency and distance, the paper argues that detours offer a way to address the contemporary, existential issues posed by the increasing rate of technological change and environmental problems.     

Comparisons of standardized and interview-informed synthesized reinforcement contingencies relative to functional analysis

We compared the functions of problem behavior identified by (a) a functional analysis (FA), (b) an interview-informed synthesized contingency analysis (IISCA) that was informed by the results of an open-ended interview and a structured observation, and (c) a standardized-synthesized contingency analysis (SSCA) in which we synthesized three common functions of problem behavior across 12 individuals in a controlled consecutive case series. We then compared outcomes across assessments. The FA was sufficient in identifying the variables maintaining problem behavior for 11 of the 12 participants, replicating the findings of Fisher, Greer, Romani, Zangrillo, and Owen (2016). Error type (i.e., false positives, false negatives) and error prevalence were similar across functions identified by the IISCA and the SSCA, calling into question the utility of the open-ended interview and the structured observation that informed the IISCA.     

Mitigating resurgence of destructive behavior using the discriminative stimuli of a multiple schedule

Results of several recent translational studies have suggested that correlating contextual or discriminative stimuli with the delivery and withholding of reinforcement for the functional communication response (FCR) may mitigate resurgence of destructive behavior, but few, if any, have isolated the effects of those stimuli. In the present study, we first trained the FCR, brought it under stimulus control of a multiple schedule, and thinned its reinforcement schedule in one stimulus context. Next, we conducted resurgence evaluations (i.e., baseline, functional communication training [FCT], extinction challenge) in two novel contexts to test the effects of the discriminative stimuli on resurgence. We programmed one context to include the (a) S^D during the FCT phase to signal the availability of reinforcement for the FCR and (b) S^Δ during a subsequent extinction challenge to signal the unavailability of reinforcement for the FCR. The other context did not include the S^D during the FCT phase, nor the S^Δ during the extinction challenge. We expected to see greater persistence of the FCR in the context that included the S^D during FCT and less persistence of the FCR and less resurgence of destructive behavior in the context that included the S^Δ during the extinction challenge. Obtained results confirmed this latter prediction, but we observed no reliable difference when the S^D was present or absent during the FCT phase. Our results have relevance for practitioners in that they provide further empirical support for the use of discriminative stimuli when treating destructive behavior.     

Item format and the structure of the buss-durkee hostility inventory

The Buss-Durkee Hostility Inventory is a widely employed multidimensional measure of aggression. Two studies, each involving the administration of both two-choice and seven-choice response format versions of the instrument, were conducted to determine if (1) the theoretical scales could be reproduced empirically, (2) the change in response format either changes or improves the structure, and (3) the structure of either response format replicates across administrations. The two-choice version provided some support for the present theoretical scoring but was not very stable across administrations. The seven-choice version resulted in a structure that was different from both the two-choice structure and theoretical scoring but was more stable across administrations.     

Mothers' and fathers' speech to infants in a teaching situation

The purpose of this study was to compare mothers' and fathers' speech to their preverbal infants in a teaching situation. Thirty-two parents of 16 8-month-olds were asked to teach their infants to put a small cube into a cup. Infant Gender (2) x Birth Order (2) x Parent (2) analyses of variance were performed with repeated measures on parent. Results indicated that fathers issued more utterances and used more words per utterance than did mothers. Although there was no difference in the proportion of imperatives used by mothers and fathers, fathers' imperatives were significantly longer than mothers'; this difference was not evident for utterances that contained indirect instructions. Mothers tended to use more exact repetitions. There were differences in parental speech related to infant gender: Parents directed more utterances, particularly utterances that contained negative statements, imperatives, and exhortations, to girls than to boys. Infant Gender x Parent effects for imperatives and exhortations indicated that these differences were especially true for fathers. Overall, it appeared that fathers made greater efforts to control the situation and to direct their infants' behavior, which might have reflected mothers' and fathers' different perceptions of both their infants' ability and their own role as teachers.     

Diabetes and psychological co-morbidity in children with a family history of early-onset type 2 diabetes

The present study was conducted to evaluate for depressive symptoms and undiagnosed diabetes in children with familial history of early-onset type 2 diabetes. Studies have shown that diabetes doubles the risk for depression and that the duration of diabetes is related to the severity of the depression. Individuals with depression are also said to be at greater risk for developing diabetes. In many cases diabetes is detected whilst screening for depression. Fifty-three children aged between 6 and 17 years were screened for diabetes and assessed for depressive symptoms using the Children Depression Rating Scale, revised version (CDRS-R). Thirty-six (68.0 %) of the children with a family history of early-onset type 2 diabetes had CDRS-R scores consistent with likely or very likely major depressive disorders. Depressive symptoms score was predicted best by the number of generations of diabetes in the family, with an associated r = .65 and adjusted R(2) = .41. As the generations of diabetes increased, the more likely it was for a child to have diabetes (r = .38, p = .005). Four (7.5%) of the children were diagnosed with diabetes. The findings suggest that depressive symptoms are common in children with a family history of early onset type 2 diabetes and may co-exist with diabetes. The independent variable that reliably predicted the child depressive symptoms score was the number of generations of diabetes in the family.     

Research in industrial and organizational psychology from 1963 to 2007: changes, choices, and trends

The authors conducted a content analysis of all articles published in the Journal of Applied Psychology and Personnel Psychology from January 1963 to May 2007 (N = 5,780) to identify the relative attention devoted to each of 15 broad topical areas and 50 more specific subareas in the field of industrial and organizational (I-O) psychology. Results revealed that (a) some areas have become more (or less) popular over time, whereas others have not changed much, and (b) there are some lagged relationships between important societal issues that involve people and work settings (i.e., human-capital trends) and I-O psychology research that addresses them. Also, much I-O psychology research does not address human-capital trends. Extrapolating results from the past 45 years to the next decade suggests that the field of I-O psychology is not likely to become more visible or more relevant to society at large or to achieve the lofty goals it has set for itself unless researchers, practitioners, universities, and professional organizations implement significant changes. In the aggregate, the changes address the broad challenge of how to narrow the academic-practitioner divide.     

An integrated model of cognitive control in task switching

A model of cognitive control in task switching is developed in which controlled performance depends on the system maintaining access to a code in episodic memory representing the most recently cued task. The main constraint on access to the current task code is proactive interference from old task codes. This interference and the mechanisms that contend with it reproduce a wide range of behavioral phenomena when simulated, including well-known task-switching effects, such as latency and error switch costs, and effects on which other theories are silent, such as with-run slowing and within-run error increase. The model generalizes across multiple task-switching procedures, suggesting that episodic task codes play an important role in keeping the cognitive system focused under a variety of performance constraints.
