Psychological Functioning of Partners of Australian Combat Veterans: Contribution of Veterans' PTSD Symptoms and Partners' Caregiving Distress

Previous research has found posttraumatic stress disorder (PTSD) symptoms in combat veterans to be associated with impaired psychological functioning in their partners. However, little is known about possible mediators of this association. The present study investigated the mediational properties of six dimensions of the revised Partners of Veterans' Distress Scale (MacDonell, Marsh, Hine, & Bhullar, 2010). Participants were 181 female partners of Australian combat veterans, age ranging from 43 and 83 years (M = 60.47, SD = 4.96), who completed measures assessing their caregiving distress levels, dyadic adjustment, mental health, and satisfaction with life. The combat veterans also completed a scale measuring their PTSD symptoms. Our results indicated that higher scores of veterans' PTSD were associated with lower levels of dyadic adjustment, mental health, and satisfaction with life in their partners. Partners reported that distress related to exhaustion and intimacy problems significantly mediated the relationship between veterans' PTSD symptoms and their partners' satisfaction with life, whereas partners' distress associated with intimacy problems was the sole significant mediator for their dyadic adjustment, and exhaustion was the only significant mediator for partners' mental health. Implications for programmes designed to address the significant needs of the partners of combat veterans are discussed.     

The family roles of siblings of people diagnosed with a mental disorder: Heroes and lost children

In order to cope with the diagnosis of mental illness in a family member, siblings may be forced to adjust their roles in the family. Taking into account the crucial role that some siblings play in caregiving for the mentally ill especially when the parents are no longer available, it is imperative to develop awareness of their unique needs and address them. Thirty‐three adult siblings of people diagnosed with a mental disorder completed the Role Behaviour Inventory (RBI) and a general questionnaire including open‐ended questions regarding the roles they played in their families of origin. Findings from the inventory and general questionnaire suggest that the well siblings score higher on two roles, the Hero and Lost Child, and lower on the Mascot and Scapegoat roles relative to a comparison group (N = 33). Being a sibling caregiver emerged as a risk factor to assume certain dysfunctional roles in the family. Implications for future research and therapy are discussed.     

Più mosso: Fast self-motion makes cyclic action faster in virtual reality

Visually induced self-motion (vection) affects the speed at which actions are performed.However, it has been unclear whether this speedy action induced by vection is based on the modulation of mental tempo. To clarify this issue, we tested whether the speed of vection influenced an observer's cyclic action related to mental tempo. Observers viewed fast and slow moving optic flow stimuli and dynamic random dots, whilst handclapping at their preferred tempo. The results revealed that the clapping rate was the fastest in the fastest optic flow condition. This effect vanished when optic flow stimuli moved fast but did not induce vection. Fast optic flow stimuli also induced larger pupil dilation, suggesting that it increased the observer's arousal level. These results suggest that illusory self-motion increased arousal levels, thereby modulating mental tempo.     

Silent music reading: Auditory imagery and visuotonal modality transfer in singers and non-singers

In daily life, responses are often facilitated by anticipatory imagery of expected targets which are announced by associated stimuli from different sensory modalities. Silent music reading represents an intriguing case of visuotonal modality transfer in working memory as it induces highly defined auditory imagery on the basis of presented visuospatial information (i.e. musical notes). Using functional MRI and a delayed sequence matching-to-sample paradigm, we compared brain activations during retention intervals (10 s) of visual (VV) or tonal (TT) unimodal maintenance versus visuospatial-to-tonal modality transfer (VT) tasks. Visual or tonal sequences were comprised of six elements, white squares or tones, which were low, middle, or high regarding vertical screen position or pitch, respectively (presentation duration: 1.5 s). For the cross-modal condition (VT, session 3), the visuospatial elements from condition VV (session 1) were re-defined as low, middle or high “notes” indicating low, middle or high tones from condition TT (session 2), respectively, and subjects had to match tonal sequences (probe) to previously presented note sequences. Tasks alternately had low or high cognitive load. To evaluate possible effects of music reading expertise, 15 singers and 15 non-musicians were included. Scanner task performance was excellent in both groups. Despite identity of applied visuospatial stimuli, visuotonal modality transfer versus visual maintenance (VT > VV) induced “inhibition” of visual brain areas and activation of primary and higher auditory brain areas which exceeded auditory activation elicited by tonal stimulation (VT > TT). This transfer-related visual-to-auditory activation shift occurred in both groups but was more pronounced in experts. Frontoparietal areas were activated by higher cognitive load but not by modality transfer. The auditory brain showed a potential to anticipate expected auditory target stimuli on the basis of non-auditory information and sensory brain activation rather mirrored expectation than stimulation. Silent music reading probably relies on these basic neurocognitive mechanisms.     

Evidence for the Role of Shape in Mental Representations of Similes

People mentally represent the shapes of objects. For instance, the mental representation of an eagle is different when one thinks about a flying or resting eagle. This study examined the role of shape in mental representations of similes (i.e., metaphoric comparisons). We tested the prediction that when people process a simile they will mentally represent the entities of the comparison as having a similar shape. We conducted two experiments in which participants read sentences that either did (experimental sentences) or did not (control sentences) invite comparing two entities. For the experimental sentences, the ground of the comparison was explicit in Experiment 1 (“X has the ability to Z, just like Y”) and implicit in Experiment 2 (“X is like Y”). After having read the sentence, participants were presented with line drawings of the two objects, which were either similarly or dissimilarly shaped. They judged whether both objects were mentioned in the preceding sentence. For the experimental sentences, recognition latencies were shorter for similarly shaped objects than for dissimilarly shaped objects. For the control sentences, we did not find such an effect of similarity in shape. These findings suggest that a perceptual symbol of shape is activated when processing similes.     

The nature of epistemic feelings

Among the phenomena that make up the mind, cognitive psychologists and philosophers have postulated a puzzling one that they have called “epistemic feelings.” This paper aims to (1) characterize these experiences according to their intentional content and phenomenal character, and (2) describe the nature of these mental states as nonconceptual in the cases of animals and infants, and as conceptual mental states in the case of adult human beings. Finally, (3) the paper will contrast three accounts of the causes and mechanisms of epistemic feelings: the doxastic account; the mental scanner account; and the heuristic mechanism account. The paper will argue in favor of the heuristic mechanism account.     

Coping with COVID-19: The sociomaterial dimensions of living with pre-existing mental illness during the early stages of the coronavirus crisis

In this article, we use the case study method to detail the experiences of five participants who reported living with pre-existing mental illness during COVID-19. We adopted a sociomaterial analytical approach, seeking to identify how human and nonhuman agents came together to generate states of wellbeing or distress during this challenging period. As the case studies show, feelings of anxiety, fear and risk were generated from the following sociomaterial conditions: loss of face-to-face contact with friends and family members; concerns about hygiene and infecting others; financial stress; loss of regular paid employment or volunteering work; public spaces; and the behaviour of unknown others in public spaces. The agents and practices that emerged as most important for opening capacities for coping and maintaining wellness during lockdown included: the space of the home; contact with a small number of intimate others; online therapeutic care; practising self-care skills learnt from previous difficult times; helping and supporting others; engaging in leisure activities; and the companionship of pets. Contributing to an affirmative approach to more-than-human assemblages of health, distress and recovery, these findings demonstrate what bodies can do in times of crisis and the agents and practices that can generate capacities for coping.     

Confinement : construction d’une nouvelle représentation sociale chez les étudiants et les salariés

IntroductionThe lockdown caused by the COVID-19 pandemic was a brutal experience that had a lasting impact on people's daily lives.ObjectiveThe construction of the social representation of this event was monitored over one year in two sampling phases (March 2020 and March 2021).MethodThe evolution of social representation was carried out using the hierarchical verbal association method and a characterisation questionnaire.ResultsThe results obtained highlighted, on one hand, the emergence of a figurative core, which is transformed into a central core by the repetition and pressure of the lockdown episodes. On the other hand, the variability of the social representation of confinement according to social status, employees structure the social representation around isolation whereas students are focused on loneliness.ConclusionThe effects of lockdown are reflected in the social representation of confinement, showing an impact on mental health, particularly on students.     

Psychological consequences of motor vehicle accidents: A systematic review

People involved in motor vehicle accidents (MVA) are at increased risk for psychological problems. Although the existing literature states that MVAs cause substantial negative mental health effects, summarizing and comparing these effects to understand their consequences could be more explored. This systematic literature review provides an overview of the literature surrounding the psychological consequences of MVAs to summarize and quantify their effects on mental health. The studies published in an English-language journal in the last 20 years (2001–2021) that present psychological consequences of MVAs were included. Web of Science, Scopus, and PubMed databases were used for the literature search. The systematic literature search found 23 eligible studies. After identifying all relevant studies on the topic, we synthesized the applied psychological assessment methods and the psychological consequences of MVAs. Current gaps in the reviewed papers and what future research are needed are also discussed. Results indicated that negative psychological consequences following an MVA are substantial, with all studies pointing to negative consequences in at least one psychopathology. Trauma-related MVA injuries are associated with elevated psychological distress, and MVA-related psychological consequences could have long-term effects if left untreated.     

Changes in sleep quality and levels of psychological distress during the adaptation to university: The role of childhood adversity

Stress-related sleep disturbances are common, and poor sleep quality can negatively affect health. Previous work indicates that early-life adversity is associated with compromised sleep quality later in life, but it is unknown whether it predicts greater declines in sleep quality during stressful life transitions. We propose and test a conceptual model whereby individuals who reported experiencing greater levels of child maltreatment would experience greater psychological distress during a stressful life transition, which in turn would contribute to greater declines in sleep quality, relative to their quality of sleep before the stressful transition. Controlling for potential confounding variables (e.g., age, gender), structural equation modelling demonstrated that psychological distress experienced during a stressful transition (i.e., beginning life at university) mediated the relationship between childhood emotional neglect and changes in sleep quality. The hypothesized model demonstrated a good overall fit to the data, χ ² (15) = 17.69, p = .279, CFI = .99, TLI = .97, SRMR = .04, RMSEA = .04 (90% CI <0.001–0.09). Emotional neglect (β = .22) was positively associated with psychological distress which in turn was positively associated with poor sleep quality (β = .31) during a stressful transition. Future research should aim to understand the specific stressors in the university environment that are most challenging to individuals who faced early-life emotional maltreatment. These findings will help inform interventions to facilitate adaptation to a new environment and improve sleep quality for these university students.
