Treating Procrastination Using Cognitive Behavior Therapy: A Pragmatic Randomized Controlled Trial Comparing Treatment Delivered via the Internet or in Groups

Procrastination is a common problem among university students, with at least half of the population reporting great difficulties initiating or completing tasks and assignments. Procrastination can have a negative impact on course grades and the ability to achieve a university degree, but can also lead to psychological distress. Cognitive behavior therapy (CBT) is believed to reduce procrastination, but few studies have investigated its effectiveness in a regular clinical setting. The current study explored its effects using a pragmatic randomized controlled trial comparing treatment delivered during 8 weeks as self-guided CBT via the Internet (ICBT) or as group CBT. In total, 92 university students with severe procrastination were included in the study (registered as a clinical trial on Clinicaltrials.gov: NCT02112383). Outcome measures on procrastination, depression, anxiety, and well-being were distributed at pre- and posttreatment as well as 6-month follow-up. An outcome measure of procrastination was administered weekly. Linear mixed and fixed effects models were calculated, along with improvement and deterioration rates. The results showed large within-group effect sizes on procrastination, Cohen’s d of 1.29 for ICBT, 95% Confidence Interval (CI) [0.81, 1.74], and d of 1.24 for group CBT, 95% CI [0.76, 1.70], and small to moderate benefits for depression, anxiety, and well-being. In total, 33.7% were regarded as improved at posttreatment and 46.7% at follow-up. No differences between conditions were observed after the treatment period, however, participants in group CBT continued or maintained their improvement at follow-up, while participants in self-guided ICBT showed some signs of deterioration. The findings from the current study suggest that CBT might be an effective treatment for those struggling with severe procrastination, but that a group format may be better for some to sustain their benefits over time and that the clinical significance of the results need to be investigated further.     

Follower Jealousy at Work: A Test of Vecchio's Model of Antecedents and Consequences of Jealousy

The present study tests the validity of Robert P. Vecchio's seminal work on antecedents and consequences of jealousy. Specifically, we examine whether antecedents such as in-group status, supervisory considerateness, and supervisory differentiation of subordinates are associated with jealousy. In addition, we examine whether jealousy is associated with the outcome variable of social loafing. Leaders (n = 73) and their followers (n = 303) working in business organizations in Norway contributed data. Multilevel analyses showed that a high-quality working relationship with one's supervisor was inversely related to reports of jealousy. In addition, supervisors who displayed high levels of considerateness, for example, by providing followers with positive emotional support, were better able to reduce subordinate jealousy. This is a novel observation since previous research failed to demonstrate such a relationship. Finally, jealousy was positively associated with social loafing, suggesting that jealous followers engaged in an active counterproductive resistance response. The present study contributes to the extant literature by identifying unexamined antecedents of jealousy and a dysfunctional behavioral response to jealousy in the form of social loafing in the workplace.     

Perceptual Error,Conjunctivism, and Husserl

Claude Romano (2012) and Andrea Staiti (2015) have recently discussed Husserl’s account of perception in relation to debates in current analytic philosophy between so-called “conjunctivists” and “disjunctivists”. Romano and Staiti offer strikingly different accounts of the nature of illusion and hallucination, and opposing readings of Husserl. Romano thinks hallucinations and illusions are fleeting, fragile phenomena, while Staiti claims they are inherently retrospective phenomena. Romano reads Husserl as being committed to a form of conjunctivism that Romano rejects in favour of a version of disjunctivism. Staiti, by contrast, claims that, from a Husserlian viewpoint, conjunctivism and disjunctivism are equally untenable. I suggest that both Romano and Staiti offer implausible accounts of illusions and hallucinations, and deliver premature verdicts on Husserl in relation to the analytic debates on perception.     

Propositions,Meaning, and Names

The object of this paper is to sketch an approach to propositions, meaning, and names. The key ingredients are a Twin‐Earth‐inspired distinction between internal and external meaning, and a middle‐Wittgenstein‐inspired conception of internal meaning as role in language system. The focus here is not on working out all the details, but on outlining the approach and showing how it offers a promising solution to the problem of the meaning of proper names. This is a plea for a neglected way of thinking about these topics.     

Exploring Associations Between Therapy Factors and Post-therapy Development After Naturalistic Psychotherapies

Earlier research on what contributes to long-term outcome after psychotherapy is scarce and scattered. Responding to this, the current study explores potential associations between therapy factors reported as salient by clients in naturalistic psychotherapy and variation in post-therapy-movement. Material from different codes and categories derived from an earlier content analysis was explored in relation to post-therapy-changes on OQ-45. In the first part of the study, two overarching themes (relational aspects and therapeutic operations) were included in a regression analysis of data from 32 clients. In the second part, more nuanced associations between material from different change- or process categories and post-therapy-movement were explored using data from 20 clients that showed reliable improvement at treatment termination but varied in later development. Reports of material related to relational aspects were recurrently associated with post-therapy improvement. Material suggesting that therapy was experienced as not fully complete (e.g., changes being superficial or wish for more treatment), as well as reports of more positive affect, correlated with later deterioration after improvement at termination. Different processes and changes appreciated by clients during therapy seem to vary as predictors of lasting gains.     

The Swedish Hayling task,and its relation to working memory,verbal ability,and speech‐recognition‐in‐noise

Cognitive functions and speech‐recognition‐in‐noise were evaluated with a cognitive test battery, assessing response inhibition using the Hayling task, working memory capacity (WMC) and verbal information processing, and an auditory test of speech recognition. The cognitive tests were performed in silence whereas the speech recognition task was presented in noise. Thirty young normally‐hearing individuals participated in the study. The aim of the study was to investigate one executive function, response inhibition, and whether it is related to individual working memory capacity (WMC), and how speech‐recognition‐in‐noise relates to WMC and inhibitory control. The results showed a significant difference between initiation and response inhibition, suggesting that the Hayling task taps cognitive activity responsible for executive control. Our findings also suggest that high verbal ability was associated with better performance in the Hayling task. We also present findings suggesting that individuals who perform well on tasks involving response inhibition, and WMC, also perform well on a speech‐in‐noise task. Our findings indicate that capacity to resist semantic interference can be used to predict performance on speech‐in‐noise tasks.     

Do Bettors Correctly Perceive Odds? Three Studies of How Bettors Interpret Betting Odds as Probabilistic Information

This paper reports on three studies investigating how accurately bettors (=people who regularly bet on sports events) interpret the probabilistic information implied by betting odds. All studies were based on data collected by web surveys prompting a total of 186 experienced bettors to convert sets of representative odds into frequency judgments. Bayesian statistical methods were used to analyze the data. From the results, the following conclusions were made: (i) On the whole, the bettors produced well‐calibrated judgments, indicating that they have realistic perceptions of odds. (ii) Bettors were unable to consciously adjust judgments for different margins. (iii) Although their interval judgments often covered the estimates implied by the odds, the bettors tended to overestimate the variation of expected profitable bets between months. The results are consistent with prior research showing that people tend to make accurate probability judgments when faced with tasks characterized by constant and clear feedback.

Money talks in attention bias modification: Reward in a dot-probe task affects attentional biases

Attention bias modification (ABM) aimed at correcting dysfunctional biases in anxiety patients has met with only mild success. Inspired by recent studies showing large effects of financial reward upon attention shifts, we contrasted effects of traditional dot-probe ABM and reward upon attention biases in a between-subject 2 × 2 design. Twenty-seven participants in group cognitive behavioural therapy (GCBT) for social anxiety disorder (SAD) were randomly assigned to undergo six sessions of a dot-probe task consisting of ABM or placebo ABM along with random or high reward following neutral stimuli. There was no influence of ABM on participants' attention bias over and above the influence of GCBT. Reward, however, had a strong influence on attention bias. Neither ABM nor reward reduced SAD symptoms over and above the effects of GCBT. The results add to the growing evidence that benefits of ABM through dot-probe training are unreliable but suggest on the other hand that rewarding attention may strongly influence dysfunctional attention biases.
