A systematic evaluation of token economies as a classroom management tool for students with challenging behavior

A two-part systematic review was undertaken to assess the effectiveness of token economies in increasing rates of appropriate classroom behavior for students demonstrating behavioral difficulties. The first part of the review utilized the recently published What Works Clearinghouse (WWC) standards for evaluating single-subject research to determine the extent to which eligible studies demonstrated sufficient evidence to classify the token economy as an evidence-based practice. The second part of the review employed meta-analytic techniques across four different types of effect sizes to evaluate the quantitative strength of the findings. Methodological strengths and weaknesses across the studies were systematically investigated. Results indicated that the extant research on token economies does not provide sufficient evidence to be deemed best-practice based on the WWC criteria.     

Effects of response time deadlines on adults' strategy choices for simple addition

In this investigation of adults' solution strategies for simple arithmetic, participants solved addition problems (e.g., 2 + 3, 8 + 7) under fast and slow response deadlines: The participants were instructed either to respond before a 750-msec warning beep, or to wait for a 2,500-msec beep before responding. After each trial, they indicated whether they had solved the problem by direct memory retrieval or by using a procedural strategy (e.g., counting, transformation). It was predicted that the fast deadline condition should curtail the use of procedural strategies, which generally are slower than direct retrieval. Furthermore, this deadline effect should be exaggerated for numerically larger problems because procedural strategies are especially slow for the larger problems. As predicted, we observed a deadline x size interaction whereby the fast deadline increased reported use of retrieval, especially for large problems. The results confirm that reported use of direct retrieval decreases systematically with elapsed time, and they provide additional evidence that young, educated adults rely substantially on procedural strategies even for simple addition.     

Cherry pit primes Brad Pitt: Homophone priming effects on young and older adults' production of proper names

Abstract— This study investigated why proper names are difficult to retrieve, especially for older adults. On intermixed trials, young and older adults produced a word for a definition or a proper name for a picture of a famous person. Prior production of a homophone (e.g., pit) as the response on a definition trial increased correct naming and reduced tip-of-the-tongue experiences for a proper name (e.g., Pitt) on a picture-naming trial. Among participants with no awareness of the homophone manipulation, older but not young adults showed these homophone priming effects. With a procedure that reduced awareness effects (Experiment 2), prior production of a homophone improved correct naming only for older adults, but speeded naming latency for both age groups. We suggest that representations of proper names are susceptible to weak connections that cause deficits in the transmission of excitation, impairing retrieval especially in older adults. We conclude that homophone production strengthens phonological connections, increasing the transmission of excitation.     

Behavioral aspects of epilepsy in children with mental retardation

Epilepsy and mental retardation, two relatively common childhood conditions, are both associated with a wide range of behavioral disorders. This article reviews the behavioral disturbances found in children with epilepsy, mental retardation, and both conditions. The behavioral disturbances found in children with epilepsy are associated with seizure-related, cognitive, developmental, and psychosocial factors. Although children with mental retardation also demonstrate a broad spectrum of behavioral disturbances, children with specific mental retardation syndromes have better-defined patterns of psychopathology. The presence of epilepsy and mental retardation seems to increase the severity of psychopathology. Further studies are needed, however, to define better the interaction of these two conditions and how they impact the behavior of children.     

Preliminary evidence of attenuated blood pressure reactivity to acute stress in adults following a recent marital separation

Objective: This study explores cardiovascular reactivity during an acute-stress task in a sample of recently separated adults.

Design: In a cross-sectional design, we examined the association between adults’ subjective separation-related distress and changes in heart rate and blood pressure across the acute-stress laboratory paradigm in a sample of 133 (n = 49 men) recently separated adults.

Main outcome measures: Heart rate (HR) and Blood pressure (BP) were recorded across a resting baseline period, a math stressor task, and a recovery period.

Results: Multilevel analyses revealed that adults who reported greater separation-related distress exhibited higher initial BP and a slower linear increase in BP across the study period. In addition, adults reporting greater separation-related distress evidenced significantly slower declines in diastolic blood pressure (DBP) following the acute-stress task. HR reactivity was not moderated by separation-related distress.

Conclusions: In recently separated adults, preliminary evidence suggests that the context of the stressors may reveal differential patterns of problematic reactivity (exaggerated or blunted responding). Greater emotional intrusion and hyperactivity symptoms may index increased risk for blunted cardiovascular reactivity to general stressors. This pattern of reactivity is consistent with models of allostatic load that emphasise the deleterious effect of hyporesponsivity to environmental demands.     

New Wine in a New Bottle: Refining The Assessment of Authentic Leadership Using Exploratory Structural Equation Modeling (ESEM)

The aim of this study was to investigate the multidimensional nature of authentic leadership (AL) through the re-evaluation of the factor structure of the most commonly used scales in AL research, the Authentic Leadership Questionnaire (ALQ) and the Authentic Leadership Inventory (ALI). Results from Exploratory Structural Equation Modeling (ESEM) conducted among 538 workers of private (57,81%) and public (42,19%)? organizations provide support for the multidimensional nature of AL but also reveal excessive content overlap across subscales and an inability to properly reflect the a priori factor structure of both instruments. Further analyses enabled the identification of key items from both instruments providing a cleaner depiction of the a priori dimensionality of AL, leading to the development of an integrated optimized measure, the Authentic Leadership Integrated Questionnaire (AL-IQ). The main contribution of this study is the proposition of an alternative and optimized measure of authentic leadership that sheds light on the distinct theoretical facets of this positive leadership style. Our data suggest that the AL-IQ is a promising tool for characterizing the strengths and weaknesses of leaders and managers’ AL practices. To our knowledge, this is the first study to use a combination of classical Confirmatory Factor Analyses (CFA) and newly developed ESEM framework to assess the construct validity (factor structure, reliability, and criterion-related validity) of the two main AL measures: the ALQ and the ALI.     

Interpersonal Transgressions and Interest in Spiritual Activities: The Role of Narcissism

As levels of narcissism rise among Americans, it is important to understand how being narcissistic affects individuals’ day-to-day lives. One domain in which narcissism may have particularly interesting effects is individuals’ spirituality. When interpersonal expectations have been violated, individuals experience a variety of emotions. Chief among these emotions is guilt, which is linked both thematically and empirically to many aspects of Western religion. Given narcissism’s complex relationship with guilt, it is important to investigate how narcissists may react to failings in the interpersonal domain, particularly in a spiritual context. The current study investigated the effects of a simulated interpersonal failing on narcissists’ interest in a variety of spiritual behaviors, including prayer, seeking spiritual guidance, and participating in spiritual activities aimed at self-enhancement. After reading a scenario designed to induce feelings associated with interpersonal failings, participants reported their interest in a variety of religious activities, including prayer. Results indicated that the manipulation tended to decrease interest in a variety of spiritual activities across the sample, but that these effects were only robust among participants high in narcissism.     

Working with chronic and relentless self‐hatred,self‐harm,and existential shame: a clinical study and reflections (Paper 2 of 2)

This second of two papers focuses on the shame which emerged in the first 14 years of analysis of a woman who was bulimic, self‐harmed, and repeatedly described herself as ‘feeling like a piece of shit’. To explore this intense and pervasive shame I draw on Jung's and Laplanche's emphasis on experiences of unresolvable, non‐pathological ‘foreignness’ or ‘otherness’ at the heart of the psyche. Images, metaphors, elements of clinical experience, and working hypotheses from a number of analytic traditions are used to flesh out this exploration. These include Kilborne's use of Pirandello's image of shame as like a ‘hole in the paper sky’ which, I suggest, points to a crack in subjectivity, and reveals our belief in the efficacy of the self to be illusory. Hultberg's observations on shame as having an existential mode (function) are also explored, as is the nature of analytic truth. Using these ideas I describe my patient's process of finding some small but freeing space in relation to her shame and self‐hatred. Through enduring and learning from her shame in analysis she realized that it was part of a desperate unconscious attempt to draw close to her troubled father and so to ‘love him better’.     

Borderline personality disorder and emotion regulation: insights from the Polyvagal Theory

The current study provides the first published evidence that the parasympathetic component of the autonomic nervous system differentiates the response profiles between individuals diagnosed with borderline personality disorder (BPD) and controls. Respiratory sinus arrhythmia (RSA), a non-invasive marker of the influence of the myelinated vagal fibers on the heart, and heart period were collected during the presentation of film clips of varying emotional content. The BPD and control groups had similar initial levels of RSA and heart period. However, during the experiment the groups exhibited contrasting trajectories, with the BPD group decreasing RSA and heart period and the control group increasing RSA and heart period. By the end of the experiment, the groups differ significantly on both RSA and heart period. The correlation between the changes in RSA and heart period was significant only for the control group, suggesting that vagal mechanisms mediated the heart period responses only in the control group. The findings were consistent with the Polyvagal Theory [Porges, S. W. (1995). Orienting in a defensive world: Mammalian modifications of our evolutionary heritage: A Polyvagal Theory. Psychophysiology, 32, 301-318; Porges, S. W. (2001). The Polyvagal Theory: Phylogenetic substrates of a social nervous system. International Journal of Psychophysiology, 42, 123-146; Porges, S. W. (2003). Social engagement and attachment: A phylogenetic perspective. Annals of the New York Academy of Sciences, 1008, 31-47.], illustrating different adaptive shifts in autonomic state throughout the course of the experiment. The BPD group ended in a physiological state that supports the mobilization behaviors of fight and flight, while the control group ended in a physiological state that supports social engagement behaviors. These finding are consistent with other published studies demonstrating atypical vagal regulation of the heart with other psychiatric disorders.
