Brain functional connectivity correlates of coping styles

Coping abilities represent the individual set of mental and behavioral strategies adopted when facing stress or traumatic experiences. Coping styles related to avoidance have been linked to a disposition to develop psychiatric disorders such as PTSD, anxiety, and major depression, whereas problem-oriented coping skills have been positively correlated with well-being and high quality of life. Even though coping styles constitute an important determinant of resilience and can impact many aspects of everyday living, no study has investigated their brain functional connectivity underpinnings in humans. Here we analyzed both psychometric scores of coping and resting-state fMRI data from 102 healthy adult participants. Controlling for personality and problem-solving abilities, we identified significant links between the propensity to adopt different coping styles and the functional connectivity profiles of regions belonging to the default mode (DMN) and anterior salience (AS) networks—namely, the anterior cingulate cortex, left frontopolar cortex, and left angular gyrus. Also, a reduced negative correlation between AS and DMN nodes explained variability in one specific coping style, related to avoiding problems while focusing on the emotional component of the stressor at hand, instead of relying on cognitive resources. These results might be integrated with current neurophysiological models of resilience and individual responses to stress, in order to understand the propensity to develop clinical conditions (e.g., PTSD) and predict the outcomes of psychotherapeutic interventions.     

Different Attentional Patterns for Regret and Disappointment: An Eye‐tracking Study

The unfavorable comparison between the obtained and expected outcomes of our choices may elicit disappointment. When the comparison is made with the outcome of alternative actions, emotions like regret can serve as a learning signal. Previous work showed that both anticipated disappointment and regret influence decisions. In addition, experienced regret is associated with higher emotional responses than disappointment. Yet it is not clear whether this amplification is due to additive effects of disappointment and regret when the outcomes of alternative actions are available, or whether it reflects the learning feature of regret signals. In this perspective, we used eye‐tracking to measure the visual pattern of information acquisition in a probabilistic lottery task. In the partial feedback condition, only the outcome of the chosen lottery was revealed, while in the complete feedback condition, participants could compare their outcome with that of the non‐chosen lottery, giving them the opportunity to experience regret. During the decision phase, visual patterns of information acquisition were consistent with the assessment of anticipated regret, in addition to a clear assessment of lotteries' expected values. During the feedback phase, subjective ratings and eye‐tracking results confirmed that participants compared their outcome with the outcome of the non‐chosen lottery in the complete feedback condition, particularly after a loss, and ignored the non‐realized outcome of the chosen option. Moreover, participants who made more visual saccades consistent with counterfactual comparisons during the feedback period anticipated regret more in their decisions. These results are consistent with the proposed adaptive function of regret. © 2016 The Authors Journal of Behavioral Decision Making Published by John Wiley & Sons Ltd.     

Duns Scotus on material substances and cognition: a discussion of two recent books

In a recent book, Thomas Ward advances an original interpretation of Duns Scotus’s hylomorphism, which stresses the ability of the parts of certain kinds of composites to exist independently from each other and from the composite to which they belong. Ward argues that the notion of essential order plays a key role in accounting for the unity of those parts in a composite. In another book, Richard Cross gives a comprehensive treatment of Duns Scotus’s theory of cognition, which proposes an interesting but controversial interpretation of Duns Scotus as introducing a distinction between object and content and defending the view that the contents of intellectual cognitive acts are determined only by their internal structure.     

Generalization of visual regularities in newly hatched chicks (<Emphasis Type="Italic">Gallus gallus</Emphasis>)

Evidence of learning and generalization of visual regularities in a newborn organism is provided in the present research. Domestic chicks have been trained to discriminate visual triplets of simultaneously presented shapes, implementing AAB versus ABA (Experiment 1), AAB versus ABB and AAB versus BAA (Experiment 2). Chicks distinguished pattern-following and pattern-violating novel test triplets in all comparisons, showing no preference for repetition-based patterns. The animals generalized to novel instances even when the patterns compared were not discriminable by the presence or absence of reduplicated elements or by symmetry (e.g., AAB vs. ABB). These findings represent the first evidence of learning and generalization of regularities at the onset of life in an animal model, revealing intriguing differences with respect to human newborns and infants. Extensive prior experience seems to be unnecessary to drive the process, suggesting that chicks are predisposed to detect patterns characterizing the visual world.     

Minimization of modal contours: an essential cross-species strategy in disambiguating relative depth

Two chromatically identical patterns, a diamond and a ladder, were shown on a computer touchscreen. Domestic hens were reinforced for pecking at the pattern that was the highest up on a grid that provided pictorial depth information, i.e. on the pattern that to a human appears as being the furthest away. Every tenth trial was a non-rewarded probe trial with the two patterns partially overlapping. In the absence of other cues depth stratification can occur on the basis of a minimization of interpolated occluding contours. In humans the diamond is usually perceived to be in front of the ladder because shorter interpolated contours are needed to account for the occlusive effect of the diamond on the ladder. The hens pecked more often at the ladder during the probe trials. The results suggest that the avian and mammalian visual systems operate along similar principles when dealing with the problem of solving occlusion indeterminacy in chromatically homogeneous patterns.

A systematic review and meta‐analysis of tertiary interventions in clinical burnout

Clinical burnout is one of the leading causes of work absenteeism in high‐ and middle‐income countries. There is hence a great need for the identification of effective intervention strategies to increase return‐to‐work (RTW) in this population. This review aimed to assess the effectiveness of tertiary interventions for individuals with clinically significant burnout on RTW and psychological symptoms of exhaustion, depression and anxiety. Four electronic databases (Ovid MEDLINE, PsychINFO, PubMed and CINAHL Plus) were searched in April 2016 for randomized and non‐randomized controlled trials of tertiary interventions in clinical burnout. Article screening and data extraction were conducted independently by two reviewers. Pooled odds ratios (ORs) and hazard ratios (HRs) were estimated with random‐effects meta‐analyses. Eight articles met the inclusion criteria. There was some evidence of publication bias. Included trials were of variable methodological quality. A significant effect of tertiary interventions compared with treatment as usual or wait‐list controls on time until RTW was found, HR = 4.5, 95% confidence interval (CI) = 2.15–9.45; however, considerable heterogeneity was detected. The effect of tertiary interventions on full RTW was not significant, OR = 1.33, 95% CI = 0.59–2.98. No significant effects on psychological symptoms of exhaustion, depression or anxiety were observed. In conclusion, tertiary interventions for individuals with clinically significant burnout may be effective in facilitating RTW. Successful interventions incorporated advice from labor experts and enabled patients to initiate a workplace dialogue with their employers.     

itsme: Interaction Design Innovating Workstations

Background  In the last 30 years, there has been little innovation in workstations. The desktop metaphor has become the standard user interface, with its pros (e.g., ease of learning) and cons (e.g., interaction constraints for skilled users, lack of context awareness). Objectives  In this paper, we present itsme, an Italian initiative to design the next-generation workstation. Interaction design is the basis of the project, as well as the involvement of a wide community of contributing users. Results  The early design phases of the project led to the definition of a new metaphor for personal computing, based on stories and venues. The metaphor is being adopted for the development of a novel front-end for the Linux operating system, aimed at fulfilling the needs and desires of knowledge workers.

Spatial reorientation in large and small enclosures: comparative and developmental perspectives

Several vertebrate species, including humans, following passive spatial disorientation appear to be able to reorient themselves by making use of the geometric shape of the environment (i.e., metric properties of surfaces and directional sense). In some circumstances, reliance on such purely geometric information can overcome the use of local featural cues (landmarks). The relative use of geometric and non-geometric information seems to depend upon, among other factors, the size of the experimental space. Evidence in non-human animals and in human infants for primacy in encoding either geometric or landmark information depending on the size of the environment is reviewed, together with possible theoretical accounts of this phenomenon.     

Psychosocial correlates of hopelessness among men

This study examined overall hopelessness, explored differences in various variables (e.g. burnout) between men reporting no/mild hopelessness and moderate/severe hopelessness, and scrutinized factors associated with hopelessness. The study design was cross-sectional, and the participants were 517 men randomly selected from the general population. About 12% of men reported moderate/severe hopelessness, and men with moderate/severe hopelessness were more often older, divorced/widowed, low educated, employed in blue-collar positions, on sick leave/other/unemployment/retirement, and financially strained. They also reported more depression, posttraumatic symptoms, and burnout. Only unemployment/retirement, depression, and posttraumatic symptoms were independently associated with an increased risk for moderate/severe hopelessness in the regression analysis, with unemployment and retirement as the most important factors. In conclusion, this study seems to corroborate previous findings and may provide new insights into men's experiences and predictors of hopelessness. More research into the predictors of hopelessness in men is warranted.
