Extensions and Mechanisms of Mindfulness‐based Cognitive Therapy: A Review of the Evidence

Mindfulness‐based cognitive therapy (MBCT) was originally developed to prevent depressive relapse and recurrence and has also been widely extended to new patient populations and target problems over the last 14 years. We provide a comprehensive review of this literature, examining the strength of the evidence base for specific populations and target problems and identifying questions for future research to address. Specifically, we review studies addressing the use of MBCT for depressive disorders (prevention of depressive relapse and treatment of residual and current depressive symptoms), the use of MBCT in the treatment or management of other mental disorders (bipolar disorder, anxiety disorders, mixed anxiety and depression symptoms, disordered eating, personality disorders, and psychosis), and the use of MBCT in behavioural medicine contexts. Additionally, we discuss the extension of MBCT during specific developmental periods, like childhood, pregnancy and post‐partum, and adult caregiving, and, finally, we address the use of MBCT among clinical health‐care providers. In the second section, we review hypothesised mechanisms of change in MBCT and reflect on implications for theories of how MBCT works in the application to various patient populations and target problems. We also consider research addressing active ingredients and what is known about the “dosage” of meditation practice. We conclude with a summary of recommendations for future research.     

Different perceptions of self‐handicapping across college and work contexts

We investigated the effectiveness of self‐handicapping as an impression management strategy in college and work contexts. In contrast to past research in which college students are both targets and perceivers, we tested whether target status and perceiver status moderate perceptions of self‐handicappers. To this end, we manipulated whether the target was a college student or an adult worker, and we recruited as perceivers both college students (Study 1) and adult workers (Study 2). We additionally manipulated the target's behavior (self‐handicapping vs. control) and outcome (success vs. failure). The results revealed that self‐handicapping protected a student target (but not a worker) from negative evaluations (e.g., ability attributions) in the eyes of college students, particularly males. However, adult workers consistently judged self‐handicapping negatively.     

The Dynamic Relationships of Work Affect and Job Satisfaction with Perceptions of Fit

This study assessed the longitudinal relationship between perceived fit (i.e., person–organization fit, person–job fit) and affect‐based variables (i.e., job satisfaction, negative affect, positive affect) using momentary (i.e., within‐person level) and stable (i.e., between‐person level) assessments of both sets of variables. In doing so, we tested 3 theoretical models of the perceived fit and work affect relationship (i.e., fit preceding affect; affect preceding fit; reciprocal fit–affect relations) to determine (a) the antecedents and consequences of fit perceptions, (b) whether fit perceptions exhibit meaningful within‐person variability, and (c) if direct fit perceptions are simply the result of affect/job satisfaction at work or can influence such work experiences. In addition, we examined whether the relationships between affect/job satisfaction and fit perceptions were homologous (i.e., similar) across the 2 levels of analysis (i.e., within‐person and between‐person). Results indicated that fit primarily preceded affect and job satisfaction at both levels of analysis, though some specific relationships exhibited reciprocal causality and others supported affect as an antecedent of fit perceptions. Our findings paint a complex picture of the causal relationship between perceived fit and work affect.     

Assessing Direct and Indirect Evidence in Linguistic Research

This paper focuses on the linguistic evidence base provided by proponents of conceptualism (e.g., Chomsky) and rational realism (e.g., Katz) and challenges some of the arguments alleging that the evidence allowed by conceptualists is superior to that of rational realists. Three points support this challenge. First, neither conceptualists nor realists are in a position to offer direct evidence. This challenges the conceptualists’ claim that their evidence is inherently superior. Differences between the kinds of available indirect evidence will be discussed. Second, at least some of the empirical evidence provided by the conceptualist is flawed. It is not obtained independently of theoretical commitments, alternative interpretations have not been ruled out, and some of the thought experiments intended to extend the evidence base are conceptually flawed. Third, the widely held assumption that rational realism disallows empirical evidence relevant to linguistics is dubious. It will be shown that the limitation imposed by rational realism concerns strictly formal linguistics. The rationalist realist has no reason to impose any restriction on the evidence relevant to psycholinguistics. I conclude that it is a mistake to dismiss realism based on the assumption that it imposes undue restrictions on evidence that is relevant to linguistics.     

How dogs scan familiar and inverted faces: an eye movement study

Faces play an important role in communication and identity recognition in social animals. Domestic dogs often respond to human facial cues, but their face processing is weakly understood. In this study, facial inversion effect (deficits in face processing when the image is turned upside down) and responses to personal familiarity were tested using eye movement tracking. A total of 23 pet dogs and eight kennel dogs were compared to establish the effects of life experiences on their scanning behavior. All dogs preferred conspecific faces and showed great interest in the eye area, suggesting that they perceived images representing faces. Dogs fixated at the upright faces as long as the inverted faces, but the eye area of upright faces gathered longer total duration and greater relative fixation duration than the eye area of inverted stimuli, regardless of the species (dog or human) shown in the image. Personally, familiar faces and eyes attracted more fixations than the strange ones, suggesting that dogs are likely to recognize conspecific and human faces in photographs. The results imply that face scanning in dogs is guided not only by the physical properties of images, but also by semantic factors. In conclusion, in a free-viewing task, dogs seem to target their fixations at naturally salient and familiar items. Facial images were generally more attractive for pet dogs than kennel dogs, but living environment did not affect conspecific preference or inversion and familiarity responses, suggesting that the basic mechanisms of face processing in dogs could be hardwired or might develop under limited exposure.     

Human melody singing by bullfinches (Pyrrhula pyrrula) gives hints about a cognitive note sequence processing

We studied human melody perception and production in a songbird in the light of current concepts from the cognitive neuroscience of music. Bullfinches are the species best known for learning melodies from human teachers. The study is based on the historical data of 15 bullfinches, raised by 3 different human tutors and studied later by Jürgen Nicolai (JN) in the period 1967–1975. These hand-raised bullfinches learned human folk melodies (sequences of 20–50 notes) accurately. The tutoring was interactive and variable, starting before fledging and JN continued it later throughout the birds’ lives. All 15 bullfinches learned to sing alternately melody modules with JN (alternate singing). We focus on the aspects of note sequencing and timing studying song variability when singing the learned melody alone and the accuracy of listening-singing interactions during alternatively singing with JN by analyzing song recordings of 5 different males. The following results were obtained as follows: (1) Sequencing: The note sequence variability when singing alone suggests that the bullfinches retrieve the note sequence from the memory as different sets of note groups (=modules), as chunks (sensu Miller in Psychol Rev 63:81–87, 1956). (2) Auditory–motor interactions, the coupling of listening and singing the human melody: Alternate singing provides insights into the bird’s brain melody processing from listening to the actually whistled part of the human melody by JN to the bird’s own accurately singing the consecutive parts. We document how variable and correctly bullfinches and JN alternated in their singing the note sequences. Alternate singing demonstrates that melody-singing bullfinches did not only follow attentively the just whistled note contribution of the human by auditory feedback, but also could synchronously anticipate singing the consecutive part of the learned melody. These data suggest that both listening and singing may depend on a single learned human melody representation (=coupling between perception and production).     

Capacity estimates in working memory: Reliability and interrelationships among tasks

The concept of capacity has become increasingly important in discussions of working memory (WM), in so far as most models of WM conceptualize it as a limited-capacity mechanism for maintaining information in an active state, and as capacity estimates from at least one type of WM task—complex span—are valid predictors of real-world cognitive performance. However, the term capacity is also often used in the context of a distinct set of WM tasks, change detection, and may or may not refer to the same cognitive capability. We here develop maximum-likelihood models of capacity from each of these tasks—as well as from a third WM task that places heavy demands on cognitive control, the self-ordered WM task (SOT)—and show that the capacity estimates from change detection and complex span tasks are not correlated with each other, although capacity estimates from change detection tasks do correlate with those from the SOT. Furthermore, exploratory factor analysis confirmed that performance on the SOT and change detection load on the same factor, with performance on our complex span task loading on its own factor. These findings suggest that at least two distinct cognitive capabilities underlie the concept of WM capacity as it applies to each of these three tasks.     

Understanding a Desireless Action as a Benevolent Action

Scholars have questioned the doctrine of desireless action in the Bhagavadgita and questioned whether Krishna’s advice is to be taken literally on the basis that the Humean account of motivation is more plausible (or not) than the anti-Humean account. In this paper, I will avoid the Humean principle debate by proposing a new way of examining the term ‘desireless action’. I aim to show that Krishna’s advice can be rendered coherent on the basis that we understand a desireless action as an action motivated by a benevolent desire. I will be referring to the notion of benevolence as constructed by Francis Hutcheson because there is a parallel between the Hutchesonian experience of benevolence and purusha, or pure consciousness. Benevolent desire results in a desireless action since to act benevolently is to act ‘disinterestedly’ and thereby accepting purusha as one’s true nature.
