Cross-Cultural and Environmental Influences on Facial Emotional Discrimination Sensitivity in 9-Year-Old Children from Swiss and Vietnamese Schools

The Other Race Effect (ORE), i.e., recognition facilitation for own-race faces, is a well-established phenomenon with broad evidence in adults and infants. Nevertheless, the ORE in older children is poorly understood, and even less so for emotional face processing. This research samples 87 9-year-old children from Vietnamese and Swiss schools. In two separate studies, we evaluated the children’s abilities to perceive the disappearance of emotions in Asian and Caucasian faces in an offset task. The first study evaluated an “emotional ORE” in Vietnamese-Asian, Swiss-Caucasian, and Swiss-Multicultural children. Offset times showed an emotional ORE in Vietnamese-Asian children living in an ethnically homogeneous environment, whereas mixed ethnicities in Swiss children seem to have balanced performance between face types. The second study compared socioemotionally trained versus untrained Vietnamese-Asian children. Vietnamese children showed a strong emotional ORE and tend to increase their sensitivity to emotion offset after training. Moreover, an effect of emotion consistent with previous observation in adults could suggest a cultural sensitivity to disapproval signs. Taken together, the results suggest that 9-year-old children can present an emotional ORE, but that a heterogeneous environment or an emotional training could strengthen face-processing abilities without reducing skills on their own-group.

Goals Do Not Buy Well-Being, but They Help

Although personal goals give meaning to life and contribute to well-being, achieving goals can become difficult in older adults faced with age-related challenges. A group of 49 older adults aged 65 to 92 years completed a semistructured interview on personal goals, obstacles to goal achievement, and contributors to well-being. Using thematic analysis, we identified several types of goals contributing to well-being and general aspects of well-being. Results revealed that, although older people might say that they no longer have major goals in their lives, they end up mentioning many activities that theoretically are goals. Many of these activities are geared toward maintaining or increasing their general well-being. Of importance, they report few complaints regarding goal achievement, which they explained by (1) reducing the number and breadth of their goals, (2) adjusting and reevaluating these goals, and (3) overcoming difficulties and stabilizing current functioning, thereby maintaining a sense of continuity and satisfactory levels of well-being. This study illustrates the interactions between resources and stressors from the viewpoint of older adults. Taken together, the results advocate for the usefulness of the functional quality of life model and proactive approaches to successful aging, and they provide directions for individualized interventions in the elderly.

Cognitive Reserve Mitigates Decline in Executive Functioning Following Hepatobiliary Diseases

The cognitive reserve hypothesis postulates that lifelong cognitive stimulation establishes a buffer that is instrumental in maintaining cognitive health. To examine this conceptual proposition in detail, we applied a novel, more general conceptual view that included recent models of vulnerability and examined whether the longitudinal association between hepatobiliary diseases and later decline in executive functioning across 6 years varied by cognitive reserve. For this purpose, we investigated longitudinal data from 897 older individuals ( M = 74.33 years) tested using the Trail Making Test (TMT) in two waves 6 years apart. Individuals reported information on key commonly used indicators of lifelong cognitive reserve build-up (i.e., education, work, and participation in leisure activity) and hepatobiliary diseases. The results revealed a significant interaction of hepatobiliary diseases with participation in leisure activity on latent change in executive functioning. Specifically, only in individuals with little (but not greater) participation in leisure activity did hepatobiliary diseases significantly predict a steeper decline in executive functioning over 6 years (i.e., increases in TMT finishing time). In conclusion, the unfavorable aftereffects of hepatobiliary diseases on a later decline in executive functioning seem to be mitigated in individuals who have built up greater cognitive reserve via participation in leisure activity during their life.

The Psychometric Properties of the Montreal Cognitive Assessment (MoCA)

The Montreal Cognitive Assessment (MoCA) is a test assessing global cognition in older adults which is often used by researchers and clinicians worldwide, although some of its psychometric properties have yet to be established. We focus on three fundamental aspects: the factorial structure of the MoCA, its general factor saturation, and the measurement invariance of the test. We administered the MoCA to a large sample of Japanese older adults clustered in three cohorts (69–71-year-olds, 79–81-year-olds, and 89–91-year-olds; N = 2,408). Our results show that the test has an overall stable hierarchical factorial structure with a general factor at its apex and satisfactory general-factor saturation. We also found measurement invariance across participants of different ages, educational levels, economic status, and sex. This comprehensive investigation thus supports the idea that the MoCA is a valid tool to assess global cognition in older adults of different socioeconomic status and age ranges.

How Musicality, Cognition and Sensorimotor Skills Relate in Musically Untrained Children

Whereas a growing corpus of research has investigated the impact of music practice on several domains of cognition, studies on the relationships between musicality and other abilities and skills in musically untrained children are scarce. The present study examined the associations between musicality, cognition, and sensorimotor skills in 69 musically untrained primary school children of around 10 years of age, using a test battery of musical, cognitive, and sensorimotor abilities. We analyzed the results using nonparametric correlations and an exploratory factor analysis. It was our anticipation that basic cognitive resources (short-term and working memory, attention, processing speed) would relate to both higher-order cognition and musicality. Results indicated that, in musically untrained children, the interconnections between musical and cognitive abilities restrain to auditory short-term and working memory. Direct associations between musicality and higher-order cognitive processes did not occur. An interesting secondary finding comprised associations between sensorimotor function, as measured by the Purdue Pegboard test, and higher-order cognition. Specifically, we found an association between bimanual coordination of fine finger dexterity and matrix reasoning. This outcome suggests that higher-order cognitive function benefits from an efficient mastering of procedural aspects of sensorimotor skills.

Coordination and Communication in Healthcare Action Teams

Communication and coordination represent central processes in healthcare action teams. However, we have a limited understanding of how expertise affects these processes and to what extent these effects are shaped by interprofessional differences. The current study addresses these questions by jointly investigating the influence of different aspects of expertise – individual expertise, team familiarity, and expertise asymmetry – on coordination quality and communication openness. We tested our propositions in two hospitals: one in Switzerland (CH, Sample 1) and one in the United Kingdom (UK, Sample 2). Both samples included two-person anesthesia action teams consisting of a physician and a nurse ( NCH = 47 teams, NUK = 48 teams). We used a correlational design with two measurement points (i.e., pre- and postoperation). To consider potential interprofessional differences, we analyzed our data with actor-partner interdependence models. Moreover, we explored differences in the effects of expertise between both hospitals. Our findings suggest that nurses’ expertise is the most important predictor of coordination quality and communication openness. Overall, differences between the two hospitals were more prevalent than interprofessional differences between physicians and nurses. The current study provides a nuanced picture of the effects of expertise, and thereby extends our understanding of interprofessional teamwork.

Modeling Value-Based Decision-Making Policies Using Genetic Programming

An important way to develop models in psychology and cognitive science is to express them as computer programs. However, computational modeling is not an easy task. To address this issue, some have proposed using artificial-intelligence (AI) techniques, such as genetic programming (GP) to semiautomatically generate models. In this paper, we establish whether models used to generate data can be recovered when GP evolves models accounting for such data. As an example, we use an experiment from decision-making which addresses a central question in decision-making research, namely, to understand what strategy, or “policy,” agents adopt in order to make a choice. In decision-making, this often means understanding the policy that best explains the distribution of choices and/or reaction times of two-alternative forced-choice decisions. We generated data from three models using different psychologically plausible policies and then evaluated the ability and extent of GP to correctly identify the true generating model among the class of virtually infinite candidate models. Our results show that, regardless of the complexity of the policy, GP can correctly identify the true generating process. Given these results, we discuss implications for cognitive science research and computational scientific discovery as well as possible future applications.

Frustration and Violence in Mobile Video Games

This study tests two competing hypotheses, one based on the general aggression model (GAM), the other on the self-determination theory (SDT). GAM suggests that the crucial factor in video games leading to increased aggressiveness is their violent content; SDT contends that gaming is associated with aggression because of the frustration of basic psychological needs. We used a 2×2 between-subject experimental design with a sample of 128 undergraduates. We assigned each participant randomly to one experimental condition defined by a particular video game, using four mobile video games differing in the degree of violence and in the level of their frustration-invoking gameplay. Aggressiveness was measured using the implicit association test (IAT), administered before and after the playing of a video game. We found no evidence of an association between implicit aggressiveness and violent content or frustrating gameplay.

Math Homework Purpose Scale

The present study evaluated the psychometric properties of the Math Homework Purpose Scale (MHPS). After randomly splitting the sample ( N = 854) into two subsamples ( n = 427 and n = 427), we carried out exploratory factor analysis (EFA) on subsample 1 and confirmatory factor analysis (CFA) on subsample 2. The Kaiser-Meyer Olkin value of .88 indicated that EFA was appropriate for subsample 1. EFA results showed that a three-factor solution explained 72.2% of the variance. All ten of the MHPS items loaded quite substantially on three factors labeled Academic, Self-Regulatory, and Approval-Seeking. CFA results further showed that the MHPS was composed of three factors: Academic, Self-Regulatory, and Approval-Seeking. From this adequate level of measurement invariance, we further examined the latent mean difference across gender for the entire sample. Our findings showed no statistically significant mean differences in Academic, Self-Regulatory, and Approval-Seeking across gender. In addition, the HMPS was found to have adequate alpha reliability coefficients and omega coefficients. Concerning the validity evidence of the MHPS, Academic, Self-Regulatory, and Approval-Seeking purposes were positively correlated with homework effort, homework completion, and math achievement. The present study provides solid evidence that the MHPS is a reliable and valid measurement of math homework purposes.
