Beyond visual imagery: How modality-specific is enhanced mental imagery in synesthesia?

Synesthesia based in visual modalities has been associated with reports of vivid visual imagery. We extend this finding to consider whether other forms of synesthesia are also associated with enhanced imagery, and whether this enhancement reflects the modality of synesthesia. We used self-report imagery measures across multiple sensory modalities, comparing synesthetes’ responses (with a variety of forms of synesthesia) to those of non-synesthete matched controls. Synesthetes reported higher levels of visual, auditory, gustatory, olfactory and tactile imagery and a greater level of imagery use. Furthermore, their reported enhanced imagery is restricted to the modalities involved in the individual’s synesthesia. There was also a relationship between the number of forms of synesthesia an individual has, and the reported vividness of their imagery, highlighting the need for future research to consider the impact of multiple forms of synesthesia. We also recommend the use of behavioral measures to validate these self-report findings.     

A temporal common ground for learning: The moderating effect of shared mental models on the relation between team learning behaviours and performance improvement

In this longitudinal study, we integrated a team process and a learning curve perspective on team learning and empirically analysed whether team learning processes lead to performance improvement. In addition, we tested whether this relation is moderated by the similarity of team members’ task, team, and temporal mental models. We tested our model on a sample of 67 teams (314 individuals) competing in a management simulation over five consecutive time periods, using random coefficient modelling (RCM). Our findings suggest that team learning behaviours do not have a direct effect on the team learning curve, but temporal and task mental models are crucial for the translation of team learning behaviours into performance improvement. We found that when teams have similar task and temporal mental models, engaging in team learning processes is beneficial, whereas, when teams have dissimilar task and temporal mental models, it is detrimental to performance improvement. We did not find a significant effect for the moderating role of team mental model similarity. Our study emphasizes the importance of integrating different perspectives on team learning and provides support for the role of team cognition as a catalyst for team learning.     

Duty of Care,Safety, Normalisation and the Mental Capacity Act: A Discourse Analysis of Staff Arguments about Facilitating Choices for People with Learning Disabilities in UK Services

The benefits of having choice and control for people with learning disabilities 1 are well documented, and front‐line carers often make efforts ensuring that these are facilitated. However, despite this, government policy reports that disempowerment within learning disability services in the UK is a persistent problem. Using critical discursive psychology, 15 interviews with support workers about empowering people with learning disabilities were analysed. Interpretative repertoires about ‘duty of care’, ‘safety’ and ‘normalisation’ and discursive strategies involving ‘comparative evaluations’ were found, which opened speaker positions of granting or withholding choice, assuming responsibility for those in care and constructing service users as lacking capacity. These resources also allowed speakers to regulate the choices of service users and to normalise limited choice in ways that undermined taking up more empowering practices. The findings may explain the persistence of disempowerment within services by indicating how such discourses are deeply entrenched in service talk and are invoked to justify disempowering practices. This is discussed in view of the implications for empowerment and also current legislative frameworks such as the Mental Capacity Act. Copyright © 2014 John Wiley & Sons, Ltd.     

Psychological predictors of eco-driving: A longitudinal study

Eco-driving has well-known positive effects on fuel economy and greenhouse-gas emissions. Moreover, eco-driving reduces road-traffic noise, which is a serious threat to the health and well-being of many people. We investigated the psychological predictors of the adoption of eco-driving from the perspective of road-traffic noise abatement. The data came from 890 car drivers who participated in a longitudinal survey over four months. Specifically, we tested the effects of the intention to prevent road-traffic noise, variables derived from the theory of planned behavior (social norm, perceived behavioral control, and attitude), and variables derived from the health action process approach (implementation intention, maintenance self-efficacy, and action control) on the intention to practice eco-driving and on eco-driving behavior. The intention to prevent road-traffic noise was not linked to the intention to practice eco-driving. The strongest predictors of the intention to practice eco-driving were attitude and perceived behavioral control. The strongest predictor of eco-driving behavior was action control. The link between behavioral intention and behavior was weak, indicating that drivers have difficulties putting their intention to practice eco-driving into action. Therefore, intervention efforts should directly address and support the transition from intention to behavior. This could be accomplished by providing reminders, which help to maintain behavioral intention, and by providing behavior feedback, which helps car drivers to monitor their behavior.     

The effects of different themes of self-disclosure on health outcomes in cancer patients—A meta-analysis

Self-disclosure (SD) is a common psychological intervention that involves expressing the patient's feelings and thoughts. The purpose of this study was to assess the effectiveness of different themes of SD on cancer patients. We searched eight databases including PubMed, Cochrane Library Trials, Web of Science, CINAHL, Medline, EMBASE, CNKI and Wanfang from inception to July 2022. Other sources included clinical data registers. The Cochrane Collaboration's tool was used to assess the risk of bias in the included studies. RevMan Analysis software 5.3 was used for data analysis. The protocol of this meta-analysis has been registered on PROSPERO (CRD42022339661). Twenty-two RCTs studies were included. The pooled results demonstrated that self-regulation self-disclosure (SRD) had significant effects on patients' sleep quality, benefit-finding, anxiety and quality of life (QOL), whereas emotional disclosure (ED) did not. Furthermore, enhanced self-regulation self-disclosure (ESRD) or cancer-related self-disclosure (CD) significantly improved patients' QOL, although health education self-disclosure (HED) and positive self-disclosure (PD) did not. Our study suggests that different themes of SD have varied effects on patients, but it remains unclear which themes to use at what point in time. Future research should investigate what themes of SD are adopted at different points in time and the duration of different periods.     

The link between involuntary non-regular employment and poor mental health: A cross-sectional study of Japanese workers

Involuntary non-regular employment is a severe inequity problem worldwide, and it may significantly affect the mental health of employees. The present study aimed to examine the relationship between employment type and mental health. Additionally, the characteristics of involuntary non-regularly employed workers were explored. An online-based cross-sectional study was conducted in Japan, and 1566 participants were included in the data analysis. The eligible participants were divided into four categories: regularly employed (n = 1092), voluntary (n = 134), average (n = 233) and involuntary (n = 107) non-regularly employed individuals, respectively. Involuntary non-regular employment was associated with greater lack of vigour, anger-irritability, fatigue, anxiety, and depression. It was higher among women, those who were single or had no childcare, and those who had lower personal income or shorter working hours, or who tended not to practice relaxation activities. Lower personal income was associated with a risk of anxiety and depressive symptoms. Those individuals experiencing involuntary non-regular employment had a higher risk of poor mental health; subgroup analysis showed that this was particularly true among men. Both encouragement of employment stability via policy reform and workplace mental health support for involuntary non-regularly employed individuals are urgent health concerns.     

Complexity of categorical syllogisms: An integration of two metrics

The complexity of categorical syllogisms was assessed using the relational complexity metric, which is based on the number of entities that are related in a single cognitive representation. This was compared with number of mental models in an experiment in which adult participants solved all 64 syllogisms. Both metrics accounted for similarly large proportions of the variance, showing that complexity depends on the number of categories that are related in a representation of the combined premises, whether represented in multiple mental models, or by a single model. This obviates the difficulty with mental models theory due to equivocal evidence for construction of more than one mental model. The “no valid conclusion” response was used for complex syllogisms that had valid conclusions. The results are interpreted as showing that the relational complexity metric can be applied to syllogistic reasoning, and can be integrated with mental models theory, which together account for a wide range of cognitive performances.     

Children's number processing is context dependent

The aim of this paper was to test the hypothesis of a context dependence of number processing in children. Fifth-graders were given two numbers presented successively on screen through a self-presentation procedure after being asked either to add or subtract or compare them. We considered the self-presentation time of the first number as reflecting the complexity of the encoding for a given planned processing. In line with Dehaene's triple-code model, self-presentation times were longer for additions and subtractions than for comparisons with two-digit numbers. Alternative interpretations of these results in terms of more cognitive effort or more mental preparation in the case of addition and subtraction than comparison are discussed and ruled out.     

The revelation of the negative side of a mental number line depends on list context: Evidence from a sign priming paradigm

Two parity judgement experiments examined how the activation of spatial-numerical associations of a single, centrally presented digit, reflected by the Spatial-Numerical Association Response Codes (SNARC) effect, is modulated by a preceding + (plus) or ? (minus) prime. The centrally presented prime prior to a digit presentation presumably triggers its positive or negative attributes. When the plus- and minus-primed trials were blocked, the left-small/right-large SNARC effects occurred regardless of prime type. When the plus- and minus-primed trials were randomly intermixed, this left-small/right-large SNARC effect occurred for plus-primed digits, but was reversed for minus-primed digits. The implications of this finding for context-dependent SNARC effects are discussed.
