Role of motor processes in extrinsically encoding mental transformations

Previous research has shown that imagined perspective rotations elicit spatial and low-level cortical motor areas of the brain when participants rely on knowledge of their physical body, or body percept (Wraga, Flynn, Boyle, & Evans, 2010). The current study used functional magnetic resonance imaging (fMRI) to investigate whether recruitment of the body percept would activate low-level cortical motor areas of the brain within other classes of mental transformations. Participants performed imagined object and perspective rotations of three-dimensional Shephard-Metzler (1971) stimuli. For each task, participants used button presses serving as virtual pointers to locate a prescribed portion of the stimuli with respect to their "right" and "left." We found low-level cortical motor activation (M1) for both mental transformations; however, the degree to which such activation related to participants' performance differed, as well as the recruitment of additional nonmotoric strategies. The results are discussed in terms of recent hypotheses regarding the role of the body percept in extrinsically encoded mental transformations.     

Improving spatial abilities through mindfulness: effects on the mental rotation task

In this study, we demonstrate a previously unknown finding that mindful learning can improve an individual’s spatial cognition without regard to gender differences. Thirty-two volunteers participated in the experiment. Baselines for spatial ability were first measured for the reaction time on the mental rotation task. Next, the participants were randomly assigned to either a mindful or mindless learning condition. After learning, the mental rotation task showed that those in the mindful learning condition responded faster than those in the mindless learning condition. This study provides promising evidence for applying mindful learning to education.

小学生的品德不良行为及其心理与行为适应问题研究

运用测量法和问卷法,以某市357名小学生为对象,探讨了小学生的品德不良行为及其心理问题与行为适应性问题,并揭示了它们之间相互的关系。结果发现:小学生的品行不良、心理健康问题和行为适应问题都存在显著的年级差异,并受学习成绩的显著影响:成绩差的学生在这些问题上最严重;且品行不良和学习问题存在显著的性别差异;小学生的品德不良水平与许多心理问题之间存在显著相关;五年级是一个转折点:在品德不良行为和许多心理问题中都是高峰,随后开始下降。     

EEG and fMRI agree: Mental arithmetic is the easiest form of imagery to detect

fMRI and EEG during mental imagery provide alternative methods of detecting awareness in patients with disorders of consciousness (DOC) without reliance on behaviour. Because using fMRI in patients with DOC is difficult, studies increasingly employ EEG. However, there has been no verification that these modalities provide converging information at the individual subject level. The present study examined simultaneous EEG and fMRI in healthy volunteers during six mental imagery tasks to determine whether one mental imagery task generates more robust activation across subjects; whether activation can be predicted from familiarity with the imagined activity; and whether EEG and fMRI converge upon the same conclusions about individual imagery performance. Mental arithmetic generated the most robust activation in the majority of subjects for both EEG and fMRI, and level of activation could not be predicted from familiarity, with either modality. We conclude that overall, EEG and fMRI agree regarding individual mental imagery performance.     

Active school travel is associated with fewer suicide attempts among adolescents from low-and middle-income countries

Background/Objective: This study explored the association between active school travel (AST) and suicide attempts among adolescents in low- and middle-income countries (LMICs). Method: We used the data from the Global School-based Health Survey, including 127,097 adolescents aged 13-17 years from 34 LMICs. A self-reported survey was used to collect data on AST and suicide attempts as well as some variables. Multivariable logistic regression was performed to assess the association between AST and suicide attempts. A meta-analysis with random effects was undertaken to identify the difference in the association between AST and suicide attempts. Results: Across all the adolescents, the prevalence of AST was 37% and the prevalence of suicide attempts was 11.60%. Adolescents who engaged in AST were less likely to have suicide attempts irrespective of gender. The country-wise analysis indicated a large inconsistency in the association between AST and suicide attempt across the countries. Conclusions: AST would appear to be a protective factor for reducing suicide attempts among adolescents. However, the association between AST and suicide attempts varied greatly across the countries. Future studies should confirm the association between AST and suicide attempts.     

Positive mental health moderates the association between depression and suicide ideation: A longitudinal study

Background/Objective: Depression and suicide ideation regularly occur together. Yet, little is known about factors that buffer individuals against the development of suicide ideation. The present study investigated, whether positive mental health buffers the association between depression and suicide ideation in a longitudinal study design. Methods: A total of 207 German students (70.3% female; age: M = 26.04, SD = 5.33) were assessed at a baseline evaluation and again twelve months later. Data were collected using self-report questionnaires. Linear hierarchical regression analysis was used to analyze the data. Positive mental health was considered to moderate the impact of depression on suicide ideation – controlling for age and gender. Results: Positive mental health was shown to moderate the impact of depression on suicide ideation: in those students who reported higher levels of positive mental health, depression severity showed no association with suicide ideation over time. Conclusion: Positive mental health seems to confer resilience and should be taken into account, when assessing individuals for suicide risk.     

Self‐esteem mediates the relationship between spirituality and subjective well‐being in Iran

Self‐esteem appears to play a central role in the spiritual life and ethical behaviour of the typical Iranian. For example, for many Iranians, humankind is believed to be the crown of creation, and each person is believed to be individually valued by God. Previous empirical studies also indicate that in Iran spirituality is positively associated with self‐esteem. On this basis, it was hypothesised that self‐esteem would be one of the mechanisms through which spirituality leads to increased mental well‐being. Mediation analysis showed that self‐esteem was a partial mediator of the spirituality–well‐being relationship. Moreover, results of moderated mediation analysis revealed that this mediation was not significantly moderated by gender, and that the indirect path through self‐esteem was significant in both genders. Implications of the results and their relevance to other western and eastern religions (e.g. Christianity and Buddhism) are discussed.     

Mental Health Utilization Among Diverse Parenting Young Couples

Mental health issues often become apparent as adolescents emerge into young adulthood. The use of mental health services is low among adolescents and young adults, and use is particularly low among minorities. In this study, we examine mental health utilization among diverse young parenting couples. The sample consisted of 296 couples. We used the social–personal framework to examine personal, family, partner relationship, and environmental predictors for using mental health services. We used the Actor–Partner Interdependence Model to assess actor and partner effects on mental health utilization. We also examined moderator effects for gender and internalizing and externalizing behaviors. We found that being female, being White, higher income, more conduct problems, and less anxious romantic attachment predicted mental health utilization. Significant moderator effects included depression × gender, depression × medical insurance, and stress × Latino. Implications for community mental health practice include conducting mental health assessments during medical visits and systematic mental health follow‐up for individuals and couples with identified mental health and support needs. Future research should include married couples and the spouse’s influence on mental health use and examine relevant parenting factors that may also predict mental health utilization among couples.
