Predicting performance on fluid intelligence from speed of processing, working memory, and controlled attention
Fluid inteliigence has been defined as an innate ability to reason which is measured
commonly by the Raven's Progressive Matrices (RPM). Individual differences in fluid
intelligence are currently explained by the Cascade model (Fry & Hale, 1996) and the
Controlled Attention hypothesis (Engle, Kane, & Tuholski, 1999; Kane & Engle, 2002). The
first theory is based on a complex relation among age, speed, and working memory which is
described as a Cascade. The alternative to this theory, the Controlled Attention hypothesis, is
based on the proposition that it is the executive attention component of working memory that
explains performance on fluid intelligence tests.
The first goal of this study was to examine whether the Cascade model is consistent
within the visuo-spatial and verbal-numerical modalities. The second goal was to examine
whether the executive attention component ofworking memory accounts for the relation
between working memory and fluid intelligence.
Two hundred and six undergraduate students between the ages of 18 and 28
completed a battery of cognitive tests selected to measure processing speed, working
memory, and controlled attention which were selected from two cognitive modalities, verbalnumerical
and visuo-spatial. These were used to predict performance on two standard
measures of fluid intelligence: the Raven's Progressive Matrices (RPM) and the Shipley
Institute of Living Scales (SILS) subtests. Multiple regression and Structural Equation
Modeling (SEM) were used to test the Cascade model and to determine the independent and
joint effects of controlled attention and working memory on general fluid intelligence.
Among the processing speed measures only spatial scan was related to the RPM. No
other significant relations were observed between processing speed and fluid intelligence. As

a construct, working memory was related to the fluid intelligence tests. Consistent with the
predictions for the RPM there was support for the Cascade model within the visuo-spatial
modality but not within the verbal-numerical modality. There was no support for the Cascade
model with respect to the SILS tests. SEM revealed that there was a direct path between
controlled attention and RPM and between working memory and RPM. However, a
significant path between set switching and RPM explained the relation between controlled
attention and RPM. The prediction that controlled attention mediated the relation between
working memory and RPM was therefore not supported.
The findings support the view that the Cascade model may not adequately explain
individual differences in fluid intelligence and this may be due to the differential relations
observed between working memory and fluid intelligence across different modalities. The
findings also show that working memory is not a domain-general construct and as a result its
relation with fluid intelligence may be dependent on the nature of the working memory
modality
Emotion regulation strategies and psychological health across cultures
Emotion regulation is important for psychological health and can be achieved by implementing various strategies. How one regulates emotions is critical for maximizing psychological health. Few studies, however, tested the psychological correlates of different emotion regulation strategies across multiple cultures. In a preregistered cross-cultural study (N = 3,960, 19 countries), conducted during the COVID-19 pandemic, we assessed associations between the use of seven emotion regulation strategies (situation selection, distraction, rumination, cognitive reappraisal, acceptance, expressive suppression, and emotional support seeking) and four indices of psychological health (life satisfaction, depressive symptoms, perceived stress, and loneliness). Model comparisons based on Bayesian information criteria provided support for cultural differences in 36% of associations, with very strong support for differences in 18% of associations. Strategies that were linked to worse psychological health in individualist countries (e.g., rumination, expressive suppression) were unrelated or linked to better psychological health in collectivist countries. Cultural differences in associations with psychological health were most prominent for expressive suppression and rumination and also found for distraction and acceptance. In addition, we found evidence for cultural similarities in 46% of associations between strategies and psychological health, but none of this evidence was very strong. Cultural similarities were most prominent in associations of psychological health with emotional support seeking. These findings highlight the importance of considering the cultural context to understand how individuals from diverse backgrounds manage unpleasant emotions.

Perceptions of the appropriate response to norm violation in 57 societies
An Author Correction to this article: DOI: 10.1038/s41467-021-22955-x.Norm enforcement may be important for resolving conflicts and promoting cooperation. However, little is known about how preferred responses to norm violations vary across cultures and across domains. In a preregistered study of 57 countries (using convenience samples of 22,863 students and non-students), we measured perceptions of the appropriateness of various responses to a violation of a cooperative norm and to atypical social behaviors. Our findings highlight both cultural universals and cultural variation. We find a universal negative relation between appropriateness ratings of norm violations and appropriateness ratings of responses in the form of confrontation, social ostracism and gossip. Moreover, we find the country variation in the appropriateness of sanctions to be consistent across different norm violations but not across different sanctions. Specifically, in those countries where use of physical confrontation and social ostracism is rated as less appropriate, gossip is rated as more appropriate.Peer reviewe
Anger and disgust shape judgments of social sanctions across cultures, especially in high individual autonomy societies
When someone violates a social norm, others may think that some sanction would be appropriate. We examine how the experience of emotions like anger and disgust relate to the judged appropriateness of sanctions, in a pre-registered analysis of data from a large-scale study in 56 societies. Across the world, we find that individuals who experience anger and disgust over a norm violation are more likely to endorse confrontation, ostracism and, to a smaller extent, gossip. Moreover, we find that the experience of anger is consistently the strongest predictor of judgments of confrontation, compared to other emotions. Although the link between state-based emotions and judgments may seem universal, its strength varies across countries. Aligned with theoretical predictions, this link is stronger in societies, and among individuals, that place higher value on individual autonomy. Thus, autonomy values may increase the role that emotions play in guiding judgments of social sanctions
Sociodemographic correlates of depressive symptoms: a cross-sectional analytic study among healthy urban Ghanaian women
Abstract Background Studies on healthy individuals that show minor signs of distress and depressionâbut that are not significant enough to be debilitating or to report to the hospital for treatmentâare rare. Our primary objective was to measure the prevalence of depressive symptoms and sociodemographic correlates among healthy women 18âyears and above in urban Accra, Ghana. Method We used secondary data from the Womenâs Health Study of Accra, Wave 1 (WHSA-1), a large scale, analytic, cross-sectional study conducted in Accra, Ghana involving 3183 women. The presence or absence of depressive symptoms within the past 30âdays was estimated from the average score on three common symptoms of depression: sleep, anxiety, and sadness. The explanatory variables were age-group, socioeconomic level, marital status, ethnicity, religion, education, employment, and parity. Frequencies and means were used to summarize categorical and continuous variables, respectively. Logistic regression analyses were employed to determine the predictors of depressive symptoms. Results The prevalence of depressive symptoms within the previous 30âdays was 26.5% (95% CI: 25.0â28.1). Women 55âyears and older were more likely than women between the ages of 18 and 24 to experience depressive symptoms (AOR 2.8, 95% CI: 2.0â4.0, pâ<â0.001), whilst women between the ages of 35 and 54 were 1.95 times more likely than women between the ages of 18 and 24 to experience depression (AOR 1.95, 95% CI: 1.40â2.70, pâ<â0.001). Self-employed women were less likely to report depressive symptoms compared to the unemployed (AOR 0.70, 95% CI: 0.56â0.87, pâ<â0.01). Akans were less likely to experience depressive symptoms compared to Ga women (AOR 0.75, 95% CI: 0.61â0.92, pâ<â0.01). Non-orthodox Christians were more likely to report depressive symptoms compared to Orthodox Christians (AOR 1.32, 95% CI: 1.09â1.60, pâ<â0.01). Conclusion The prevalence of symptoms of depression among healthy urban Ghanaian women is high. Older women, those with low education, and unemployed women appear to be at higher risk for depression and therefore should be targeted for interventions. Groups at risk for depressionâespecially older adults or individuals under economic strainâshould be targeted for mood assessment as part of routine medical care
The Moderating Effects of Age and Education on Gender Differences on Gender Role Perceptions
Individual differences in gender role perceptions have been described copiously in the psychological literature. The effects of education and gender have been established cross-culturally. The joint effects of education and gender have not however been discussed adequately, especially among African populations where there are strong expectations of these effects. In the current study, we explored these known effects among a heterogeneous urban population. Four hundred and seventy-six (476) respondents made up of high and low education groups were selected for this study. We examined the extent to which men and women will adopt traditional/egalitarian gender role attitudes and if age and education moderate established gender differences in gender role attitudes using Williams and Bestâs (1990) traditional and modern gender role scale. We found differences on traditional gender role perceptions based on education. We also found that while there was no gender difference on the traditional component, education seemed to minimise femalesâ perceptions of traditional roles but not males. We did observe that both females and young adults endorsed more modern perceptions of gender roles. The results seemed to support the notion that males are less likely to change from socialisation practices that encourage male hegemony. Implications of the findings are discussed.

Predictors of quality of life of TB/HIV co-infected patients in the Northern region of Ghana
Abstract Background Tuberculosis (TB) and human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) co-morbidity continues to be a serious worldwide health issue, particularly in Sub-Saharan Africa. Studies on the quality of life (QOL) of TB/HIV co-infected patients guide stakeholders on the delivery of patient-centred healthcare. This study evaluated QOL of TB/HIV co-infected individuals and its contributing factors. Methods We conducted a cross-sectional study among TB/HIV co-infected patients, receiving treatment at clinics in the Northern Region of Ghana. Simple random sampling technique was used to select 213 patients from 32 clinics. We gathered information on patientsâ QOL using the World Health Organization QOL-HIV BREF assessment tool. At a 5% level of significance, multiple logistic regression analyses were carried out to find correlates of QOL among the patients. Results The mean age of the patients was (38.99â±â14.00) years with most, 33.3% (71/213) aged 30â39 years. Males constituted 54.9% (117/213). About 30.0% (64/213) of the patients reported a good QOL. Being employed (aORâ=â5.23, 95% CI: 1.87 â 14.60), and adhering to treatment (aORâ=â6.36, 95% CI: 1.51 â 26.65) were significantly associated with a good QOL. Being depressed (aORâ=â0.02, 95% CI: 0.03 â 0.29), stigmatized (aORâ=â0.31, 95% CI : 0.11 â 0.84), and not exercising (aORâ=â0.28, 95% CI: 0.12 â 0.67) were negatively associated with a good QOL. Conclusion Less than one-third of TB/HIV co-infected patients in the region have good QOL. To guarantee good QOL, modifiable predictors such as patientsâ physical activity and medication adherence should be targeted by the National AIDS and TB Control Programs
Knowledge of developmental disabilities and referral sources among health workers in two Ghanaian hospitals
Proper treatment of developmental disabilities requires health workers to have adequate knowledge of etiology and referral procedures. There is a dearth of research on knowledge of developmental disabilities among health workers in Ghana. The purpose of this study was to document knowledge about developmental disorders, causes, and referral procedures among health workers. Researchers used a successive free-listing method to interview 37 health workers. Developmental disabilities which present with physical symptoms were the most salient disorders identified among health workers, while learning disabilities and attention deficit disorder were largely overlooked. The most commonly listed developmental disabilities were cerebral palsy, Down syndrome, and autism spectrum disorder. Respondents had limited knowledge about the causes of and referral resources for developmental disabilities. Results show the need for continuing medical education, public awareness, and enhanced resources to support the identification and care of children with developmental disabilities in Ghana
