Does high educational level protect against intellectual decline in older adults?: A 10‐year longitudinal study

This study examined the relation between educational level and intellectual change in Japanese older adults. Participants (age = 65–79 years, n = 593) comprised the first‐wave participants of the National Institute for Longevity Sciences‐Longitudinal Study of Aging (NILS‐LSA). They were followed for 10 years and were tested six times. Educational levels were divided into two groups (low‐educated or high‐educated), and intellectual changes for the 10 years were assessed using the Japanese Wechsler Adult Intelligence Scale‐Revised Short Forms (JWAIS‐R‐SF); subtests included Information, Similarities, Picture Completion, and Digit Symbol. General linear mixed‐model analyses revealed that education had not affected 10‐year changes of the Information, Similarities, and Picture Completion subtest scores. In contrast, education was significantly associated with a change in the Digit Symbol subtest score; individuals with higher levels of education showed greater decline than those with less education, although they had higher ability at every time point. These findings suggest that higher education does not protect against intellectual decline in late life, although it is associated with long‐term individual differences in intelligence.     

Awe or horror: differentiating two emotional responses to schema incongruence

ABSTRACT

Experiences that contradict one's core concepts (e.g. of the world, people, the self) elicit intense emotions. Such schema incongruence can elicit awe, wherein experiences that are too vast to understand with existing cognitive schemata cause one to feel that schemata should be updated [i.e. a “need for cognitive accommodation” (NFA); Keltner & Haidt, 2003. Approaching awe, a moral, spiritual, and aesthetic emotion. Cognition and Emotion, 17(3), 297–314]. However, other emotional responses to schema incongruence, such as horror, have not been investigated. The current studies compared awe and horror to investigate if they are distinct emotional responses to schema incongruence. Study 1 observed significant differences between awe and horror in cognitive appraisals (e.g. certainty, legitimacy), indicating several areas of dissimilarity. Study 2 found evidence that awe and horror are both responses to schema incongruence, as schema incongruence and NFA were salient in awe and horror, but not a contrast emotion. However, awe and horror were elicited by different types of schema incongruence: awe by spiritual vastness, horror by extremity. Awe-eliciting experiences also appeared to be easier to assimilate than horrifying experiences, as NFA and uncertainty were significantly lower in awe than in horror. Differences in the functions of horror and awe are also discussed.     

Differential Mastication Kinematics of the Rabbit in Response to Food and Water: Implications for Conditioned Movement

Analysis of naturalistic chewing patterns may provide insight into mapping the neural substrates of jaw movement control systems, including their adaptive modification during the classically conditioned jaw movement (CJM) paradigm. Here, New Zealand White rabbits were administered food and water stimuli orally to evaluate the influence of stimulus consistency on masticatory pattern. Chewing patterns were recorded via video camera and movements were analyzed by computerized image analysis. The mandibular kinematics, specifically the extent of dorsal/ventral, medial/lateral, and rostral/caudal movement, were significantly larger in food-evoked than water-evoked chewing. Water-evoked chewing frequency, however, was significantly higher than that of food-evoked movements. In light of known cortical mastication modulatory centers, our findings implicate different neural substrates for the responses to food and water stimuli in the rabbit. A detailed delineation of jaw movement patterns and circuitry is essential to characterize the neural substrates of CJM.     

Ghrelin stimulates corticotropin-releasing factor and vasopressin gene expression in rat hypothalamic 4B cells

Corticotropin-releasing factor (CRF) and arginine vasopressin (AVP) play a central role in regulating the stress response. In response to stress, CRF and AVP neurons in the hypothalamic paraventricular nucleus secrete the peptides to stimulate the release of adrenocorticotropic hormone from the anterior pituitary. Ghrelin, an endogenous ligand of the growth hormone-releasing peptide receptors (GHSR), has been shown to stimulate the release of CRF and AVP by rat hypothalamic explants. However, little is known about the ability of the ghrelin signaling pathways to activate the CRF and AVP genes in the hypothalamus. In the present study, we examined the direct effect of ghrelin on CRF and AVP gene expression in hypothalamic 4B cells, which show the characteristics of the hypothalamic parvocellular paraventricular nucleus neurons. Cells were transfected with CRF or AVP promoter to examine the activity of each promoter. Ghrelin stimulated the promoter activities and mRNA levels for both CRF and AVP. The involvement of a protein kinase pathway was examined using inhibitors. Protein kinase A and phospholipase C pathways were shown to be involved in ghrelin-induced increases in both CRF and AVP promoter activities. GHSR type 1a (GHSR1a) mRNA levels were also increased by ghrelin, and these ghrelin-induced levels were suppressed by a GHSR1a antagonist. Thus, ghrelin-dependent pathways are involved in the regulation of CRF and AVP gene expression in the hypothalamus: ghrelin, an orexigenic hormone, stimulates CRF, an anorexigenic/anxiogenic factor in the hypothalamus, resulting in hypothalamic-pituitary-adrenal axis activation to stimulate the release of glucocorticoids.     

Putting the “We” Into Well‐being: Using Collectivism‐Themed Measures of Well‐Being Attenuates Well‐being's Association With Individualism

Studies repeatedly have documented that societal well‐being is associated with individualism. Most of these studies, however, have conceptualized/measured well‐being as individual life satisfaction—a type of well‐being that originates in Western research traditions. Drawing from the latest research on interdependent happiness and on family well‐being, we posit that people across cultures pursue different types of well‐being, and test whether more collectivism‐themed types of well‐being that originate in Confucian traditions also are associated with individualism. Based on data collected from 2,036 participants across 12 countries, we find support for the association between individual life satisfaction and individualism at the societal level, but show that well‐being's association with individualism is attenuated when some collectivism‐themed measures of well‐being are considered. Our article advances knowledge on the flourishing of societies by suggesting that individualism may not always be strongly linked with societal well‐being. Implications for public policies are signaled.     

Cultural variation in implicit independence: An extension of Kitayama et al. ()

Previous research shows that European Americans are consistently more independent (or less interdependent) than Japanese when implicit indices are used to assess independence (vs. interdependence). The present work extended this evidence by including a novel implicit association test (IAT), as an index of implicit attitude towards independence and interdependence. Consistent with the previous findings, as compared to Japanese, Americans were significantly higher in multiple indices of implicit independence (vs. interdependence) including personal (vs. social) self‐definition, experience of disengaging (vs. engaging) emotions and personal (vs. social) form of happiness. Furthermore, as compared to Japanese, Americans had a significantly more positive implicit attitude towards independence assessed with the IAT. As also observed in the previous research, explicit measures showed inconsistent cross‐cultural patterns. Lastly, we observed little statistical within‐culture coherence among the implicit measures of independence (vs. interdependence), consistent with a view that the implicit indices capture alternative ways for individuals to achieve the cultural mandate of independence or interdependence.     

Perception of achievement attribution in individual and group contexts: Comparative analysis of Japanese, Korean, and Asian-American results

The present study focuses on the relational dynamics between individual and group attributions and examines cultural variations of people's perceptions of self-enhancing and group-enhancing attributions. Middle school students in Japan, Korea and the USA (Hawaii) were asked to read a vignette and to evaluate the stimulus person who makes an internal or external attribution for his personal or team's success. The results revealed that: (i) the self-effacing attributor was perceived as likable by the participants from all three cultures, but as less self-confident by Asian-Americans; and (ii) although Japanese and Koreans share similar cultural backgrounds, they had different preferences for the group-enhancing or group-effacing attributions. The different systems of self-enhancement across cultures are discussed.     

Caught Between Culture,Society, and Globalization: Youth Marginalization in Post‐industrial Japan

In this article, we review the controversies regarding how representative Japanese psychological patterns are of an interdependent orientation and discuss understanding these controversies in the context of seeing Japanese youth as being marginalized in their own society. We review specific studies on shifting values and motivational patterns at the individual level and incorporate a sociological perspective to understand the causes of these patterns at the social‐structural level. We argue that traditional cultural practices are maintained to protect the senior elites of Japan at a cost of increasing the rift between culture, society, and post‐industrial trends. The unsustainability of this rift then ends up asymmetrically marginalizing Japanese youth who bear the brunt of the cost of institutional resistance to globalization pressures. Therefore, the “demotivation” and psychological distancing from interdependent norms among marginalized Japanese youth are not the causes of marginalization, but rather, are an outcome of it. Thus, we argue that psychology of globalization and the psychology of marginalization can go hand‐in‐hand, especially for societies with dominant institutions that are interdependent, relatively inflexible, seniority‐based, and are entering a post‐industrial economy due to globalization demands.     

Interdependent Happiness: Theoretical Importance and Measurement Validity

We proposed the concept of “interdependent happiness,” which is interdependently pursued and attained. A nine-item Interdependent Happiness Scale (IHS) was developed to measure the happiness of individuals who are relationally oriented, quiescent and ordinary. Interdependent happiness correlated with both subjective well-being (SWB) and interdependent self-construal among Japanese students (Study 1); their SWB was more likely to be explained by IHS than the SWB of American students (Study 2); and IHS explained the SWB of working adults in the US, Germany, Japan, and Korea (Study 3) and Japanese adults and elders from collectivist regions of the country (Study 4). Cultural and cross-cultural psychological perspectives were incorporated to shed new light on collective happiness     

Silent or Talking in the Classroom: Implicit Self-Stereotyping Among Asian and White Students

In academic settings, Asian students are often described as less talkative than White students. We provide an account of this phenomenon based on research on cultural influences on the self, self-categorization, and implicit social cognition. We hypothesized that the classroom context activates a process of implicit self-stereotyping. Asian and White participants were asked to imagine themselves in a classroom or leisure context. Next, they completed Implicit Association Tests assessing their self-concept, ethnic stereotypes, and ethnic identification. In the classroom context only, ethnic stereotypes accounted for a more reserved self-concept among Asian participants and a more talkative self-concept among White participants.
