One size doesn’t fit all: the influence of supervisors’ power tactics and subordinates’ need for cognitive closure on burnout and stress

The present research investigated the notion of fit between supervisors’ power tactics and subordinates’ need for cognitive closure (NFCC) on subordinates’ burnout and stress. Subordinates who tend to avoid ambiguity (high NFCC) were expected to experience relatively less burnout (Study 1) and stress (Study 2) if their supervisors utilize harsh (controlling and unequivocal) power tactics and more burnout and stress if their supervisors utilize soft (autonomy-supportive and equivocal) power tactics. In contrast, it was expected that subordinates who avoid firm and binding conclusions (low NFCC) would experience relatively less burnout and stress if their supervisors use soft power tactics and more burnout and stress if they use harsh power tactics. Two studies conducted in diverse organizational settings supported these hypotheses. Collectively, these results support the conclusion that soft (vs. harsh) power tactics are not always associated with better (vs. worse) organizational outcomes. Theoretical and practical implications for organizations are discussed.     

Clients’ experiences of dynamic interpersonal therapy (DIT): opportunities and challenges for brief,manualised psychodynamic therapy in the NHS

Dynamic interpersonal therapy (DIT) is a brief manualised psychodynamic intervention for depression. This is a first study exploring clients’ experiences of DIT specifically and brief, manualised psychodynamic psychotherapy (PP) in general. Interpretative phenomenological analysis was the methodology employed. Five participants completed a semi-structured interview, three weeks to ten months after completing DIT. The scores of pre- and post-therapy outcome measures of depression and anxiety were also available. Two emerging superordinate themes are presented here: (1) ‘The Distinct Features of DIT’, referring to how its therapeutic style and time limitations were experienced and (2) the ‘Impact of Therapy’, referring to perceived outcomes. While previous findings showed that therapist’s perceived limited activity in long-term PP was experienced as hindering/unhelpful, the perceived sense of direction in DIT appeared adequate to most participants. Secondly, the time limitations provoked complex responses. Reactions to the distinct elements of DIT are to be treated both as therapeutic opportunities and as challenges. Further, in line with psychoanalytic theory, most participants described relational changes that went beyond symptom relief and remained in progress after therapy ended. Intriguingly, there was no consistency between participants’ qualitative accounts of change and the scores of the outcome measures.     

Psychiatric Disorders and Childhood Parental Loss in Obesity: Relationship with the Mode of Weight Gain

We assessed the association between psychiatric disorders, childhood parental loss, and weight gain mode in 150 obese patients seeking bariatric surgery and with a history of sudden or gradual weight gain mode. Subjects with sudden weight gain mode (47%) showed significantly higher bipolar II disorder (p < .001), childhood parental death (p < .01), and separation (p < .01), but lower pure hypomania (p < .001) prevalence than subjects with gradual weight gain mode. We found preliminary evidence that lifetime bipolar spectrum disorders and childhood parental loss may influence weight gain mode in obese subjects. These findings may contribute to predict patients’ weight trajectories and implement preventive interventions.     

Quantified Propositional Logic and the Number of Lines of Tree-Like Proofs

There is an exponential speed-up in the number of lines of the quantified propositional sequent calculus over Substitution Frege Systems, if one considers proofs as trees. Whether this is true also for the number of symbols, is still an open problem. This revised version was published online in June 2006 with corrections to the Cover Date.     

Hidden reality: sexual sphere in brain tumor patients

Most reports emphasize that tumors and their treatments affect sexual function. To date, no studies have focused on sexual functioning in patients with brain tumors. Our study’s objective is to describe the sexual sphere of patients with brain tumors and examine the possible differences between patients who reported sexual dysfunctions and those who did not with respect to their psychological and functional status. We tested 46 patients with brain tumors. We used an ad hoc questionnaire to assess patients’ subjective perception of their own sexual sphere. To assess patients’ psychological status, we used the following questionnaires: Hospital Anxiety and Depression Scale; Psychological Distress Inventory; EORTC QLQ-C30; EORTC QLQ-BN20. Fifty-eight percent of patients reported sexual disturbance. Our data showed that a lack of or decrease in sexual desire is the most common sexual problem reported by our patients (56%). Patients with sexual problems reported higher levels of anxiety and depression and a worse self-reported quality of life (QoL) than did those who did not perceive adverse changes in their sexual sphere. In addition, we found that patients with a better performance status (KPS) reported more changes in sexual behaviors than did those who had performance difficulties. Of the patients, 15.2% received information regarding possible changes in the sexual sphere by physicians. Additionally, 10.8 of 15.2% of the patients reported having explicitly requested information from physicians. The study demonstrated a relation between QoL and sexual function. Therefore, it would be important to encourage clinicians to ask questions regarding patients’ sexual issues, thus providing them with an opportunity to expose their difficulties and receive adequate support.     

Executive dysfunction affects word list recall performance: Evidence from amyotrophic lateral sclerosis and other neurodegenerative diseases

The Rey Auditory Verbal Learning Test (RAVLT) is widely used in clinical practice to evaluate verbal episodic memory. While there is evidence that RAVLT performance can be influenced by executive dysfunction, the way executive disorders affect the serial position curve (SPC) has not been yet explored. To this aim, we analysed immediate and delayed recall performances of 13 non‐demented amyotrophic lateral sclerosis (ALS) patients with a specific mild executive dysfunction (ALSci) and compared their performances to those of 48 healthy controls (HC) and 13 cognitively normal patients with ALS. Moreover, to control for the impact of a severe dysexecutive syndrome and a genuine episodic memory deficit on the SPC, we enrolled 15 patients with a diagnosis of behavioural variant of frontotemporal dementia (bvFTD) and 18 patients with probable Alzheimer's disease (AD). Results documented that, compared to cognitively normal subjects, ALSci patients had a selective mid‐list impairment for immediate recall scores. The bvFTD group obtained low performances with a selectively increased forgetting rate for terminal items, whereas the AD group showed a disproportionately large memory loss on the primary and middle part of the SPC for immediate recall scores and were severely impaired in the delayed recall trial. These results suggested that subtle executive dysfunctions might influence the recall of mid‐list items, possibly reflecting deficiency in control strategies at retrieval of word lists, whereas severer dysexecutive syndrome might also affect the recall of terminal items possibly due to attention deficit or retroactive interference.     

Neural substrates of the ‘low‐level’ system for speech articulation: Evidence from primary opercular syndrome

We describe a patient with progressive disorder of speech, without language impairment (opercular syndrome). Morphometric analysis confirmed asymmetric volume reduction of the precentral areas (>left). Diffusion imaging showed significant white matter changes in the left frontal lobe, with specific involvement of the left corticobulbar tract and connections between supplementary/pre‐supplementary motor areas and the frontal operculum (frontal aslant tract). We suggest that the organization of expressive language includes a ‘low level’ motor system principally distributed in the left hemisphere that shows specific susceptibility to neurodegeneration, distinct from neural systems subtending praxic, and cognitive aspects of language.     

Analogous selection processes in declarative and procedural working memory: N-2 list-repetition and task-repetition costs

Working memory (WM) holds and manipulates representations for ongoing cognition. Oberauer (Psychology of Learning and Motivation, 51, 45–100, 2009) distinguishes between two analogous WM sub-systems: a declarative WM which handles the objects of thought, and a procedural WM which handles the representations of (cognitive) actions. Here, we assessed whether analogous effects are observed when participants switch between memory sets (declarative representations) and when they switch between task sets (procedural representations). One mechanism assumed to facilitate switching in procedural WM is the inhibition of previously used, but currently irrelevant task sets, as indexed by n-2 task-repetition costs (Mayr & Keele, Journal of Experimental Psychology: General, 129(1), 4–26, 2000). In this study we tested for an analogous effect in declarative WM. We assessed the evidence for n-2 list-repetition costs across eight experiments in which participants switched between memory lists to perform speeded classifications, mental arithmetic, or a local recognition test. N-2 list-repetition costs were obtained consistently in conditions assumed to increase interference between memory lists, and when lists formed chunks in long-term memory. Further analyses across experiments revealed a substantial contribution of episodic memory to n-2 list-repetition costs, thereby questioning the interpretation of n-2 repetition costs as reflecting inhibition. We reanalyzed the data of eight task-switching experiments, and observed that episodic memory also contributes to n-2 task-repetition costs. Taken together, these results show analogous processing principles in declarative and procedural WM, and question the relevance of inhibitory processes for efficient switching between mental sets.     

Emotions associated with counterfactual comparisons drive decision-making in Footbridge-type moral dilemmas

Based on the dual-process theory of moral judgment, it has been suggested that in Footbridge-type dilemmas the anticipation of the emotional consequences of causing intentional harm might contribute to the decision of rejecting utilitarian resolutions. However, no empirical data have been reported on the emotions felt by participants after their decisions, and the role played by emotions in Trolley-type dilemmas remains to be determined. The present study investigated the specific emotions engaged both after decision choices and after the generation of the counterfactual scenario in Trolley- and Footbridge-type dilemmas. The results support the idea that in Footbridge-type dilemmas decision-making is driven by the attempt to minimize the aversive emotional state evoked by the decision outcome. A greater increase in emotional intensity was found overall for Footbridge-type than Trolley-type dilemmas after the counterfactual generation following typical (non-utilitarian) choices, with guilt, regret, and shame being the emotions that increased most. Critically, in Footbridge-type dilemmas only, typical choices were predicted by the increase in regret intensity experienced after counterfactual generation.     

Re-conceptualizing Self,Speaker, and Body: Applying an Enactive and Conversation Analytic Approach to Selfhood and Cognition

In this article I review significant contributions to the subfield of Embodied Cognition that formulate an inclusive account of the body's role in cognitive processes. I argue that a reconceptualization of the mind–body problem must take into account some notion of the self as a nonlocalized, transient phenomenon that emerges through day-to-day interaction. Drawing on literature from epistemology, phenomenology, and Conversation Analysis, I aim to revise contributions that rely on essentialized notions of the self and speaker, in terms of an enactive and Conversation Analytic approach to selfhood and cognition.
