Defining reactivity: how several methodological decisions can affect conclusions about emotional reactivity in psychopathology

There are many important methodological decisions that need to be made when examining emotional reactivity in psychopathology. In the present study, we examined the effects of two such decisions in an investigation of emotional reactivity in depression: (1) which (if any) comparison condition to employ; and (2) how to define change. Depressed (N = 69) and control (N = 37) participants viewed emotion-inducing film clips while subjective and facial responses were measured. Emotional reactivity was defined using no comparison condition (i.e., raw scores), baseline comparison condition (i.e., no stimulus presented), and neutral comparison condition (i.e., neutral stimulus presented). Change in emotional reactivity was assessed using four analytic approaches: difference scores, percentage change, residualised change, and ANCOVA. Results differed among the three comparison conditions and among several of the analytic approaches. Overall, our investigation suggests that choosing a comparison condition and the definition of change can significantly influence the presence of group differences in emotional reactivity. Recommendations for studies of emotional reactivity in psychopathology are discussed.

Systematic approach to the diagnosis of lysosomal storage disorders

Disorders that arise as a result of lysosomal dysfunction represent some of the most challenging diagnostic problems in medicine. Not only are these disorders infrequently seen, but they may also present with signs and symptoms that mimic perinatal injury, food intolerance, or the sequellae of neonatal infection. Misidentification can lead to significant delay in diagnosis. Ironically, as the prevailing economic climate places increasing time constraints on practicing physicians, medical research is providing treatment strategies and management techniques that are most effective if applied early in the course of the disease. Most lysosomal storage disorders can now be definitively diagnosed once the signs are recognized. In many cases the benefits of early diagnosis, enlightened management, and appropriate referral are considerable. The aim of this paper is to demystify this elusive class of diseases, to promote clinical vigilance in their detection, and to provide a systematic approach to diagnosis when clinical suspicion is aroused.     

Understanding Workaholism: Data Synthesis, Theoretical Critique, and Future Design Strategies

Workaholism involves a personal reluctance to disengage from work, which is evidenced by the tendency to work irrespective of external demands. While the term workaholism has been widely used by the public for over 30 years, scientists are only beginning to explore the behavior in depth. To date, most research has occurred on an ad hoc basis, emerging from a wide variety of paradigms without being explicitly linked to theory. The current article presents three methods for defining workaholism and a précis of relevant measures, then provides an integrated overview of research relating workaholism to individual well-being. Three models implicit in existing workaholism research (addiction, learning, and trait theory) are expounded and critiqued, and four new procedures for researching workaholism are suggested. Finally, an integrated, multidisciplinary approach is proposed as an essential element in encouraging rigorous debate and continued development of workaholism theory.     

The role of maternal responsivity in the development of children with intellectual disabilities

There is growing evidence that cumulative exposure to highly responsive parenting styles throughout the early childhood period may provide a variety of important child benefits in terms of language, cognitive, social, and emotional development. We view maternal responsivity as a dynamic construct of central importance to the development of children with intellectual disabilities just as it is for typically developing children. In this study, we selectively review the theoretical and conceptual evidence for the effects of responsivity on development, discuss factors known to influence responsivity including the nature of a child's disability, and review intervention approaches intended to enhance maternal responsivity. We conclude with a set of recommendations for future research.     

The contents of perceptual hypotheses: Evidence from rapid resumption of interrupted visual search

Observers can resume a previously interrupted visual search trial significantly more quickly than they can start a new search trial (Lleras, Rensink, & Enns, 2005). This rapid resumption of search is possible because evidence accumulated during the previous exposure, a perceptual hypothesis, can carry over to a subsequent presentation. We present four interrupted visual search experiments in which the content of the perceptual hypotheses used during visual search trials was characterized. These experiments suggest that prior to explicit target identification, observers have accumulated evidence about the locations, but not the identities, of local, task-relevant distractors, as well as preliminary evidence for the identity of the target. Our results characterize the content of perceptual search hypotheses and highlight the utility of interrupted search for studying online search processing prior to target identification.     

The irrationality of recalcitrant emotions

A recalcitrant emotion is one which conflicts with evaluative judgement. (A standard example is where someone is afraid of flying despite believing that it poses little or no danger.) The phenomenon of emotional recalcitrance raises an important problem for theories of emotion, namely to explain the sense in which recalcitrant emotions involve rational conflict. In this paper I argue that existing ‘neojudgementalist’ accounts of emotions fail to provide plausible explanations of the irrationality of recalcitrant emotions, and develop and defend my own neojudgementalist account. On my view, recalcitrant emotions are irrational insofar as they incline the subject to accept an evaluative construal that the subject has already rejected.

Comparison of delay discounting of different outcomes in cigarette smokers,smokeless tobacco users,e-cigarette users,and non-tobacco users

Delay discounting is the process by which a commodity loses value as the delay to its receipt increases. Rapid discounting predicts various maladaptive behaviors including tobacco use. Typically, delay discounting of different outcomes has been compared between cigarette smokers and nonsmokers. To better understand the relationship of delay discounting to different modes of tobacco use, we examined the differences in delay discounting of different outcomes between cigarette smokers, smokeless tobacco users, e-cigarette users, and non-tobacco users. In the present study, all participants completed 8 titrating delay-discounting tasks: $100 gain, $500 gain, $500 loss, alcohol, entertainment, food, a temporary health gain, and a temporary cure from a disease. Non-tobacco users discounted most outcomes less than tobacco users overall; however, there were no differences in discounting among the different types of tobacco users. These results suggest that nicotine consumption of any kind is associated with a higher degree of impulsivity compared to non-tobacco users. Adoption of tobacco products that have been perceived as less harmful (e.g., e-cigarettes) is not associated with a baseline difference or decrease in delay discounting if adopted after a history of cigarette use.
