A lateralization of function approach to sex differences in spatial ability: a reexamination

The current study assessed the lateralization of function hypothesis (Rilea, S. L., Roskos-Ewoldsen, B., & Boles, D. (2004). Sex differences in spatial ability: A lateralization of function approach. Brain and Cognition, 56, 332–343) which suggested that it was the interaction of brain organization and the type of spatial task that led to sex differences in spatial ability. A second purpose was to evaluate explanations for their unexpected findings on the mental rotation task. In Experiment 1, participants completed the Water Level, Paper Folding, and mental rotation tasks (using an object-based or self-based perspective), presented bilaterally. Sex differences were only observed on the Water Level Task; a right hemisphere advantage was observed on Water Level and mental rotation tasks. In Experiment 2, a human stick figure or a polygon was mentally rotated. Men outperformed women when rotating polygons, but not when rotating stick figures. Men demonstrated a right hemisphere advantage when rotating polygons; women showed no hemisphere differences for either stimulus. Thus, hemisphere processing, task complexity, and stimulus type may influence performance for men and women across different spatial measures.     

The mental time line: An analogue of the mental number line in the mapping of life events

A crucial aspect of the human mind is the ability to project the self along the time line to past and future. It has been argued that such self-projection is essential to re-experience past experiences and predict future events. In-depth analysis of a novel paradigm investigating mental time shows that the speed of this “self-projection” in time depends logarithmically on the temporal-distance between an imagined “location” on the time line that participants were asked to imagine and the location of another imagined event from the time line. This logarithmic pattern suggests that events in human cognition are spatially mapped along an imagery mental time line. We argue that the present time-line data are comparable to the spatial mapping of numbers along the mental number line and that such spatial maps are a fundamental basis for cognition.     

Predicting Nonresponse Bias from Teacher Ratings of Mental Health Problems in Primary School Children

The impact of nonresponse on estimates of mental health problems was examined in a prospective teacher screen in a community survey of 9,155 7–9 year olds. For 6,611 of the children, parents consented to participation in the actual study (Responders), while for 2,544 children parental consent was not obtained (Nonresponders). The teacher screen involved assessment of a broad set of symptoms of mental health problems and functional impairment. Calculations of non-response coefficients, a function of effect sizes and non-response proportion, revealed only ignorable nonresponse bias for both mean scores and correlations. However, the results from binary logistic regressions revealed that children ascribed signs of mental health problems by their teachers were less likely to participate. This was most frequent among children with only moderate symptoms. However, it also involved children with high symptom scores related to inattention, hyperactivity, emotions and peer relationship problems. These findings suggest that measures based on effect size can underestimate the magnitude of non-response bias and that a logistic regression approach may be more appropriate for studies geared at estimating prevalence of mental health problems in children. The study was financially supported by the Norwegian Research Council, The Norwegian Directorate for Health and Social Affairs, Western Norwegian Regional Health Authority, the L. Meltzer legacy for the University of Bergen, and the City of Bergen.     

Agency and Communion Related to Mental Health in Japanese Young Adults

Based on Bakan’s (1966) theory, Helgeson (1994) presented a conceptual model of the relationships of biological sex, agency, and communion with psychological and physical well-being. This study was designed to examine the relationships of mitigated and unmitigated agency (M, M-) /communion (F, F-) with mental health in Japanese young adults. Participants were 602 (247 men, 355 women) undergraduate students and vocational school students in Japan. The average age of the participants was 20.0 years (SD=4.1). The results showed that communion (F) was positively associated with social support, unmitigated communion (F-) was strongly and positively associated with dysphoria for both men and women, unmitigated agency (M-) was also positively associated with dysphoria for women, and agency (M) was negatively associated with dysphoria for women. Both M and F were positively associated and F- was negatively associated with self-esteem for both men and women. M may moderate F-, and social support may moderate M-, for women. Thus our findings partially supported Helgeson’s model.     

Contextual effects on number-time interaction

Time perception has long been known to be affected by numerical representations. Recent studies further demonstrate that when participants estimate the duration of Arabic numbers, number magnitude, though task-irrelevant, biases duration judgment to produce underestimation for smaller numbers and overestimation for larger numbers. Such effects were found in the present study to be significantly reduced when a weight unit gram was suffixed to the numbers rendering the mental magnitude differences between different numbers less distinctive. The effects were enhanced when a different unit kilogram was suffixed to the numbers enlarging the perceived magnitude differences between different numbers. The results indicate that effects of number magnitude on duration estimation should not be attributed to the mathematical differences between numbers but to how the numbers are perceived to differ from each other in magnitude in specific contexts when they denote concrete items. The results also provide new evidence for the theoretical proposal of a common generalized magnitude system and indicate that the system must be extended to include other action-oriented magnitudes, such as weight.     

The “religiosity gap” in a clinical setting: experiences of mental health care consumers and professionals

ABSTRACT

In Western countries, professionals in mental health care (“professionals”) tend to be less religious than “consumers”. This qualitative study explores the meaning of this “religiosity gap” for professionals and consumers in mental health care. Both a regular, secular and a Christian clinic in the Netherlands participated in this study. Content analysis was applied to 35 consumer interviews and 18 interviews with professionals. Consumers reported negative experiences (e.g., perceived disrespect and a lack of confidence) and/or negative expectations (e.g., misunderstanding and misinterpretation) related to a religiosity gap. They also mentioned advantages of a “religiosity match”, like safety and confidence and appreciated professionals’ religious/spiritual self-disclosure. Professionals in secular care setting tended to avoid religion and spirituality. In both clinics, they tended to neutralise religious/spiritual differences and be reticent in self-disclosure. Professionals are recommended to recognise the relevance of a religiosity gap and to consider different strategies in approaching religion/spirituality.     

Selective interference with image retention and generation: Evidence for the workspace model

We address three types of model of the relationship between working memory (WM) and long-term memory (LTM): (a) the gateway model, in which WM acts as a gateway between perceptual input and LTM; (b) the unitary model, in which WM is seen as the currently activated areas of LTM; and (c) the workspace model, in which perceptual input activates LTM, and WM acts as a separate workspace for processing and temporary retention of these activated traces. Predictions of these models were tested, focusing on visuospatial working memory and using dual-task methodology to combine two main tasks (visual short-term retention and image generation) with two interference tasks (irrelevant pictures and spatial tapping). The pictures selectively disrupted performance on the generation task, whereas the tapping selectively interfered with the retention task. Results are consistent with the predictions of the workspace model.     

Relationship between Mental Health and Burden among Primary Caregivers of Outpatients with Schizophrenia

There is growing recognition that caring for a patient with schizophrenia often results in high levels of perceived burden and poorer overall mental health for caregivers. A quantitative cross‐sectional design and standardized instruments were used to collect data from 355 primary caregivers of adults in outpatient care with schizophrenia in China. Structural equation modeling was used to examine the association between caregiver burden and mental health among primary caregivers and whether this association is influenced by personality, coping style, and family functioning, based on a diathesis–stress perspective. Goodness‐of‐fit indices (χ²/df = 1.406, GFI = 0.919, CFI = 0.957, etc.) confirmed that the modified model fit the data well. In line with the diathesis–stress model, and with this study's hypotheses, we found that caregiver burden was significantly related to mental health outcomes directly. The final model showed that personality traits, coping style, and family function influenced the relationship between caregiver burden and mental health. The neuroticism personality traits have a direct effect on caregiver burden and family functioning in this sample. Coping style had a direct effect on the caregiver burden, and family functioning had a direct effect on the caregiver burden. Our final model about primary caregivers can be applied clinically to predict mental health outcomes from caregiver burden.     

Gaining perspectives: A scoping review of research assessing depressive symptoms in athletes

The aim of this review was to 1) describe methodological characteristics of the research that has assessed depressive symptoms in athletes, and 2) to map the variables that have been tested in relation to these symptoms. A review framework proposed by Arksey and O’Malley (2005) was utilized, and of 6983 records screened, 157 studies were included. Most studies were cross-sectional, with samples including current male and female athletes from multiple sports and levels. Non-athlete comparison groups frequently consisted of student samples. Twenty-eight different depression scales were utilized, of which CES-D, BDI, BDI-II, and the PHQ-9 were most common. The most commonly tested variables in relation to depressive symptoms were identified as proximal (micro- and meso-level) sport-specific (e.g. type of sport) (36.4%) and generic (e.g. sex) (31.5%) factors. Within-individual vulnerabilities (e.g. neurocognitive performance) accounted for 17.2%, while comorbid disorders accounted for 9.3%, and macro-level variables (e.g. ethnicity) for 5% of all observations. Longitudinal studies within specific sports are needed to understand the relative influence of sport-specific and generic factors on depressive symptoms in athletes. Few studies explored sociocultural or macro-level factors, and research concerning within-individual vulnerability is fragmented and needs to be further explored to inform individual-level support and prevention initiatives.
