Opposite effects of anxiety and depressive symptoms on executive function: The case of selecting among competing options

People constantly face the need to choose one option from among many, such as when selecting words to express a thought. Selecting between many options can be difficult for anyone, and can feel overwhelming for individuals with elevated anxiety. The current study demonstrates that anxiety is associated with impaired selection across three different verbal tasks, and tests the specificity of this finding to anxiety. Anxiety and depression frequently co-occur; thus, it might be assumed that they would demonstrate similar associations with selection, although they also have distinct profiles of symptoms, neuroanatomy and neurochemistry. Here, we report for the first time that anxiety and depressive symptoms counter-intuitively have opposite effects on selection among competing options. Specifically, whereas anxiety symptoms are associated with impairments in verbal selection, depressive symptoms are associated with better selection performance. Implications for understanding the mechanisms of anxiety, depression and selection are discussed.     

Development of Prospective Memory: Tasks Based on the Prefrontal-Lobe Model

This study investigated the development of prospective memory using tasks based on the prefrontal-lobe model. Three groups each of 30 children, adolescents, and young adults were compared on prospective-memory performance using ongoing tasks with two levels of cognitive demand (low and high), and two levels of importance (unstressed and stressed) of remembering prospective cues. The Self-Ordered Pointing Task (SOPT), Stroop Color Word Interference Test, and Tower of London were also used to assess relationships between prospective memory and prefrontal-lobe functions. The children remembered fewer prospective cues than either the adolescents or adults, but the adolescents and adults remembered equally well. This trend increased significantly as the cognitive demand of the ongoing tasks increased. However, stressing or not stressing the importance of remembering made no difference to prospective-memory performance. Performance on the SOPT and Stroop Colour Word Interference predicted performance on the high- but not on the low-demand condition. These findings implicate the maturation of the brain's prefrontal region in the development of prospective memory.     

Combating the mental health stigma with nostalgia

We report research implicating nostalgia as an intrapersonal means of warding off the stigmatization of persons with mental illness. We hypothesized and found that nostalgia about an encounter with a person with mental illness improves attitudes toward the mentally ill. In Experiment 1, undergraduates who recalled an encounter with a mentally ill person while focusing on central (vs. peripheral) features of the nostalgia prototype reported a more positive outgroup attitude. This beneficial effect of nostalgia was mediated by greater inclusion of the outgroup in the self (IOGS). In Experiment 2, undergraduates who recalled a nostalgic (vs. ordinary) interaction with a mentally ill person subsequently showed a more positive outgroup attitude. Results supported a serial mediation model whereby nostalgia increased social connectedness, which predicted greater IOGS and outgroup trust. IOGS and outgroup trust, in turn, predicted more positive outgroup attitudes. We ruled out alternative explanations for the results (i.e., mood, perceived positivity, and typicality of the recalled outgroup member). The findings speak to the intricate psychological processes underlying the prejudice‐reduction function of nostalgia and their interventional potential. Copyright © 2013 John Wiley & Sons, Ltd.     

Posture affects emotional responses: A Head Down Bed Rest and ERP study

Body posture, mainly represented by horizontal bed rest, has been found to be associated with cortical inhibition, altered perceptual and cognitive processing. In the present research, the influence of Head Down Bed Rest (HDBR) – a condition also termed simulated microgravity – on emotional responses has been studied. Twenty-two male subjects were randomly assigned to either Sitting Control or HDBR group. After 3-h, subjects attended to a passive viewing emotional task in which 75 IAPS slides, divided into 25 pleasant, 25 neutral and 25 unpleasant, were presented in random order for 6 s each, while EEG was recorded from F7, F8 and Pz locations. Results showed in Sitting Controls the expected greater P300 and Late Positive Potential (LPP) to pleasant and unpleasant compared with neutral slides, an effect which indicates greater processing of emotional arousing stimuli. The HDBR group showed smaller non-significant differences among all emotional conditions in both ERP components. Arousal and valence subjective evaluations, typically less sensitive to experimental manipulation, did not differentiate groups. The observed ability of HDBR to inhibit cortical emotional responses raises an important issue on the risk that astronauts underestimate a dangerous/threatening situation or that long-term bedridden inpatients develop depressive symptoms.     

Deeper attentional masking by lateral objects in children with autism

Autism spectrum disorder (ASD) is often associated with a detail-oriented perception and overselective attention in visual tasks, such as visual search and crowding. These results were obtained manipulating exclusively the spatial properties of the stimuli: few is known about the spatio-temporal dynamics of visual processing in ASD. In this study we employed an attentional masking (AM) paradigm comparing children with ASD and IQ-matched typically developing (TD) controls. The AM effect refers to an impaired identification of a target followed by a competitive masking object at different proximities in space and time. We found that ASD and TD groups did not differ in the AM effect provoked by the competitive object displayed in the same position of the target. In contrast, children with ASD showed a deeper and prolonged interference than the TD group when the masking object was displayed in the lateral position. These psychophysical results suggest that the inefficient attentional selection in ASD depends on the spatio-temporal interaction between competitive visual objects. These evidence are discussed in the light of the ASD altered neural connectivity hypothesis and the reentrant theory of perception.     

Differential Attention as a Mechanism of Change in Parent–Child Interaction Therapy: Support from Time-Series Analysis

Although many interventions address children’s externalizing behavior problems, negative treatment outcomes remain common. Reasons for success or failure are frequently unclear, due in part to a lack of research identifying treatment change mechanisms. The current study evaluated differential attention as a mechanism of change in Parent–Child Interaction Therapy (PCIT), a treatment for children with externalizing problems. Using sequential coding and time-series analysis, we examined parent–child interactions across treatment for three families. Contrary to hypotheses, child prosocial behaviors and parent skill use held steady or decreased across coaching periods, with the exception of one family, where the parent’s skill use increased during coaching. Partial support was found for the hypothesis that parent differential attention would predict child prosocial behavior in the next minute. These results provide support for differential attention as a mechanism of change, but also demonstrate that this factor is not the only such mechanism.     

The experience of attending a lay-led,chronic disease self-management programme from the perspective of participants with multiple sclerosis

A lay-led, community-based intervention, the Chronic Disease Self-Management Course (CDSMC) is effective for a range of long-term health conditions (e.g. arthritis, heart disease). However, the perceived value and experience of the CDSMC for people with Multiple Sclerosis (MS) has not been examined. The present qualitative study addressed this omission. Ten participants with MS (7 female; age range 35 to 60 years; disease duration 4 to 19 years) were interviewed before attending the CDSMC and at 4-month follow-up. Data were analysed using Framework Analysis. Some participants learned new self-management techniques and reported enhanced confidence (self-efficacy), whereas other participants were already confident in their self-management ability and found the CDSMC acted as a reminder of techniques previously used. Relaxation, pacing, and goal setting were particularly valuable for managing fatigue. Goal setting helped some participants to build confidence. Participants valued meeting similar others including those with different conditions. The CDSMC was an opportunity for social comparison and inspirational role modelling. Improvements to the CDSMC were suggested, including the addition of specific MS information. Overall, the CDSMC was viewed as a valuable source of new skills and a reminder of previously learned self-management skills, particularly in the context of managing fatigue. Gender differences emerged.     

Focusing on Patient Needs and Preferences May Improve Genetic Counseling for Colorectal Cancer

During cancer genetic counseling, different items which counselors consider important are discussed. However, relatively little empirical evidence exists regarding the needs and preferences of counselees. In this study needs and preferences were assessed from counselees with a personal and/or family history of colorectal cancer (CRC), who were referred for genetic counseling regarding CRC. They received a slightly modified version of the QUOTE-GENE^ca questionnaire prior to their first visit to the Hereditary Cancer Clinic. Response rate was 60 % (48/80 participants). Counselees rated the importance of 45 items assessing their needs and preferences regarding the content and process of genetic counseling. Participants rated the items regarding discussion of information about their familial CRC risk (100 %) and preventive options (98 %) as important or very important. Fewer participants rated items concerning general information on genetics as important. Sensitive communication during counseling was considered very important by a large percentage of counselees. Generally, no major differences were seen between participants in relation to individual characteristics. Our data suggest that focusing on familial CRC risk and surveillance options, in combination with sensitive communication may lead to better satisfaction with genetic counseling.     

Ethnic Differences in Parents' Attitudes toward Girls' Use of Aggression

Few studies have attempted to explain ethnic differences in female aggression. The degree to which ethnic differences exist in the influence of parents' approval of aggression on their preadolescent daughters' use of physical, verbal, and relational aggression was explored in a sample of 97 parent-child dyads. Results indicate that European American parents were more disapproving of their daughters' aggressive behavior than were African American parents. Parents' attitude toward aggression was predictive of European American girls' use of physical and verbal aggression and African American girls' use of relational aggression. Implications for aggression prevention and intervention for girls are discussed.     

Nanotechnology, uncertainty and regulation. A guest editorial

Nanotechnology has been established as a priority research and policy focus, cutting across several R&D fields from pharmaceutics, food and electronics. The raise of nanotechnologies has been accompanied by an enduring uncertainty characterising the developments of the scientific knowledge related to this field, as well as the social trajectories of technological applications. Such a condition inevitably affects regulatory responses to such technologies, their development and their uses. This special issue addresses this junction between uncertainty and regulation. With no ambition of providing a comprehensive assessment of such a complex issue, this collection of articles examines three relevant dimensions for understanding uncertainty in nanotechnology regulation, which can be useful entry points for further reflection and discussion: scientific uncertainty, regulatory fragmentation, social actors’ opinions about and attitudes to nanotechnology and regulation.
