Strategic value-directed learning and memory in Alzheimer's disease and behavioural-variant frontotemporal dementia

In healthy adults, the ability to prioritize learning of highly valued information is supported by executive functions and enhances subsequent memory retrieval for this information. In Alzheimer's disease (AD) and behavioural-variant frontotemporal dementia (bvFTD), marked deficits are evident in learning and memory, presenting in the context of executive dysfunction. It is unclear whether these patients show a typical memory bias for higher valued stimuli. We administered a value-directed word-list learning task to AD (n = 10) and bvFTD (n = 21) patients and age-matched healthy controls (n = 22). Each word was assigned a low, medium or high point value, and participants were instructed to maximize the number of points earned across three learning trials. Participants’ memory for the words was assessed on a delayed recall trial, followed by a recognition test for the words and corresponding point values. Relative to controls, both patient groups showed poorer overall learning, delayed recall and recognition. Despite these impairments, patients with AD preferentially recalled high-value words on learning trials and showed significant value-directed enhancement of recognition memory for the words and points. Conversely, bvFTD patients did not prioritize recall of high-value words during learning trials, and this reduced selectivity was related to inhibitory dysfunction. Nonetheless, bvFTD patients showed value-directed enhancement of recognition memory for the point values, suggesting a mismatch between memory of high-value information and the ability to apply this in a motivationally salient context. Our findings demonstrate that value-directed enhancement of memory may persist to some degree in patients with dementia, despite pronounced deficits in learning and memory.     

He Lin and German Philosophy in the Zhanguoce School: An Idealist Philosopher on History and Cultural Reform

The Zhanguoce School emerged in 1940 and actively responded to the crisis caused by the Sino-Japanese War. The cultural morphology of Oswald Spengler (1880–1936) inspired most of the leading Zhanguoce scholars to reflect on the culture, history, and status quo of China. They believed that China was suffering from a total war with world superpowers and that it was in a new Warring States epoch; they thus advocated radical cultural reform as a necessary condition for victory and invoked Nietzschean philosophy to champion heroism and power. However, He Lin 賀麟 (1902–92), a philosopher in this school, looked to Georg Wilhelm Friedrich Hegel (1770–1831) and Johann Gottlieb Fichte (1762–1814) for different theories of cultural reform and history. This article examines He’s integration of the philosophies of Hegel and Fichte into his cultural and historical thought. Based on the Hegelian notion of Spirit, He rethought the nature of culture and the relationship between Chinese and Western cultures; he also interpreted history by comparing the historical theories of Hegel and Wang Fuzhi 王夫之 (1619–92). Furthermore, He investigated individual realization with reference to Fichte and repudiated radical heroism.     

Correlates of Academic Procrastination and Students’ Grade Goals

This study examined correlates of academic procrastination and students’ grade goals in a sample of 226 undergraduates from Singapore. Findings indicated that self-efficacy for self-regulated learning was significantly and negatively related to procrastination. High self-efficacy for self-regulated learning also predicted students’ expectations of doing well and low self-efficacy for self-regulated learning predicted students’ expectations of not doing well academically. Additionally, help-seeking predicted students’ expectations of doing well academically while academic stress predicted students’ expectations of not doing well academically. Implications for education and educational practice were discussed. This project was partially supported by the Undergraduate Research Experience on Campus (URECA) program from Nanyang Technological University, Singapore.     

Patterns of psychosocial risk and long-term outcomes in rheumatoid arthritis

This study examined the extent to which patterns of psychosocial risk were uniquely associated with long-term outcomes of rheumatoid arthritis (RA), after demographic factors and self-reported symptom severity over time were accounted for. Data were collected over an 8-year period from 561 individuals with RA who were participants in the ongoing UCSF RA Panel Study in 1995. Panel members were interviewed annually, using a comprehensive structured telephone interview. Psychosocial factors assessed included mastery, perceptions about adequacy of social support, the impact of RA and self-assessed ability to cope with RA and satisfaction with health and function. Cluster analysis of psychosocial factors identified three distinctive patterns/levels of psychosocial risk (high, medium and low risk). The unique effects of psychosocial risk status on changes in depressive symptoms, basic functional limitations, global pain ratings and average annual doctor visits over an 8-year period were estimated, using growth curve analyses. Analyses controlled for demographic factors (gender, marital/partner status, education, age and ethnicity), disease duration and year in the panel and time-varying self-reported symptom severity (morning stiffness, swollen joint counts, co-morbid medical conditions, extra-articular RA symptoms and changes in joint appearance), as well as self-reported medications taken over time (disease-modifying antirheumatic drugs [DMARDS], and prednisone). Overall, 32.4% of total variance in depressive symptoms was accounted for by the fully-estimated model, with 12.9% uniquely associated with psychosocial risk status. Half of the total variance (50.0%) in basic functional limitations was explained, with 12.1% of variance uniquely predicted by psychosocial risk status. Psychosocial risk status accounted for comparatively little total explained variance in global pain ratings (total = 38.6%, incremental = 3.2%), and average annual total doctor visits (total = 10.9%, incremental = 1.5%). Thus, psychosocial risk factors are more closely linked to depressive symptoms and function over time. Global pain and utilization appear to be more closely related to disease factors.

Weight‐Based Discrimination in Occupational Hiring and Helping Behavior1

This study explored weight‐based discrimination using a range of weight categories, as represented by images of real women with known body mass index (BMI). In the first study, 30 men rated each image according to likelihood of occupational hiring for a managerial post. In the second study, 28 men rated the same images for likelihood of helping behavior following a minor accident. Study results showed that individuals with a slender body weight (BMI = 19–20) were most likely to be hired and helped, while obese (BMI > 30) participants were least likely to be hired and helped. However, results also showed that emaciated (BMI < 15) individuals were likely to be discriminated against. Implications for real‐life settings are discussed.     

Factor structure of the Center for Epidemiological Studies Depression Scale in Hong Kong adolescents

We present data from the Center for Epidemiological Studies-Depression Scale (CES-D; Radloff, 1977) for 2 samples of Hong Kong community adolescents (combined N = 1,385). The 4 positive affect items related poorly to the remainder of the scale. Using 16 items, the data were consistent with 2 models with highly correlated factors: (a) a 2-factor model, 1 of which merged somatic and affective items, and (b) a 3-factor model separating somatic, depressed, and interpersonal items. Correlations with related constructs provide preliminary support of validity. Hong Kong adolescents are influenced both by traditional concepts of mind-body holism and Western psychological models separating psychological and somatic symptoms.     

Identity‐based motivation: Constraints and opportunities in consumer research

This commentary underscores the integrative nature of the identity-based motivation model (Oyserman, D. (2009). Identity-based motivation: Implications for action-readiness, procedural-readiness, and consumer behavior. Journal of Consumer Psychology, 19(3) (this issue)). We situate the model within existing literatures in psychology and consumer behavior, and illustrate its novel elements with research examples. Special attention is devoted to, 1) how product- and brand-based affordances constrain identity-based motivation processes and, 2) the mindsets and action tendencies that can be triggered by specific cultural identities in pursuit of consumer goals. Future opportunities are suggested for researching the antecedents of product meanings and relevant identities.     

Learning Through Shared Christian Praxis: Reflective Practice in the Classroom

The cultivation of reflective practice has become a commonly accepted goal of theological education. However, theological educators must face the challenge of teaching and assessing reflective practice. Hypothesizing that this concern is best addressed in community, the authors of this article devised a collaborative action‐research project using Thomas Groome's “shared Christian praxis” model. They describe the ways in which they have, over the course of the project, modified their pedagogy to improve their students' reflection on practice.     

Impact of rumination versus distraction on anxiety and maladaptive self-beliefs in socially anxious individuals

A large body of experimental evidence has demonstrated the adverse effects of rumination on depressive mood and cognitions. In contrast, while prominent models of social phobia (Clark & Wells, 1995; Rapee & Heimberg, 1997) have proposed rumination as a key maintaining factor, the effects of rumination in social anxiety have not been extensively explored. In a sample of (N = 93) undergraduates, this study investigated the impact of rumination versus distraction following a social-evaluative task on anxiety and another key component of social phobia: maladaptive self-beliefs. Relative to distraction, rumination maintained anxiety in both high and low socially anxious individuals, and maintained unconditional beliefs in high socially anxious individuals. The results support models of social phobia and also suggest important theoretical extensions. Implications for the treatment of social anxiety are discussed.
