Specificity in autobiographical memory narratives correlates with performance on the Autobiographical Memory Test and prospectively predicts depressive symptoms

Reduced autobiographical memory specificity (AMS) is an important cognitive marker in depression that is typically measured with the Autobiographical Memory Test (AMT; Williams & Broadbent, 1986). The AMT is widely used, but the over-reliance on a single methodology for assessing AMS is a limitation in the field. The current study investigated memory narratives as an alternative measure of AMS in an undergraduate student sample selected for being high or low on a measure of depressive symptoms (N=55). We employed a multi-method design to compare narrative- and AMT-based measures of AMS. Participants generated personally significant self-defining memory narratives, and also completed two versions of the AMT (with and without instructions to retrieve specific memories). Greater AMS in self-defining memory narratives correlated with greater AMS in performance on both versions of the AMT in the full sample, and the patterns of relationships between the different AMS measures were generally similar in low and high dysphoric participants. Furthermore, AMS in self-defining memory narratives was prospectively associated with depressive symptom levels. Specifically, greater AMS in self-defining memory narratives predicted fewer depressive symptoms at a 10-week follow-up over and above baseline symptom levels. Implications for future research and clinical applications are discussed.     

老年高血压降压药物的选择

随着社会进入老龄化,我国老年高血压的绝对人数逐渐上升,目前我国60岁以上人群高血压的患病率为49％,80岁以上人群高血压的患病率为90％.高血压对于老年人的危害更为严重,老年高血压患者发生靶器官损害以及相关死亡的危险性显著增高,故合理地控制老年患者的血压,对于降低病死率,改善生活质量有着重要的意义.但老年高血压有其特殊的病理生理及临床特点,要求我们在治疗药物的选择上要兼顾多方面因素,合理用药,减少副作用,降低病死率.     

Mapping novel labels to actions: how the rhythm of words guides infants' learning

We investigated the effect of lexical stress on 16-month-olds' ability to form associations between labels and paths of motion. Disyllabic English nouns tend to have a strong-weak (trochaic) stress pattern, and verbs tend to have a weak-strong (iambic) pattern. We explored whether infants would use word stress information to guide word-action associations during learning. Infants heard two novel words with either verb-like iambic stress or noun-like trochaic stress. Each word was paired with a single novel object performing one of two path actions and was tested using path-switch trials. Only infants in the iambic stress condition learned the association between the novel words and the path actions. To further investigate infants' difficulty in mapping the trochaic labels to the actions, we conducted an additional study in which infants were given an object switch task using the trochaic labels. In this case, infants were able to associate the trochaic labels with the objects, providing further support that infants use lexical stress to guide label-referent associations. This study demonstrates that by 16months, English-learning infants have developed a bias to expect disyllabic action labels to have iambic stress patterns, consistent with native language stress patterns.     

On the dynamics of action representations evoked by names of manipulable objects

Two classes of hand action representations are shown to be activated by listening to the name of a manipulable object (e.g., cellphone). The functional action associated with the proper use of an object is evoked soon after the onset of its name, as indicated by primed execution of that action. Priming is sustained throughout the duration of the word's enunciation. Volumetric actions (those used to simply lift an object) show a negative priming effect at the onset of a word, followed by a short-lived positive priming effect. This time-course pattern is explained by a dual-process mechanism involving frontal and parietal lobes for resolving conflict between candidate motor responses. Both types of action representations are proposed to be part of the conceptual knowledge recruited when the name of a manipulable object is encountered, although functional actions play a more central role in the representation of lexical concepts.     

A Review of Carolyn Chen’s <Emphasis Type="Italic">Getting Saved in America: Taiwanese Immigration and Religious Experience</Emphasis>

Becoming religious among immigrants to the U.S. is undoubtedly a complex transformation. It takes place with both external sociocultural conditions and internal spiritual and psychological volitions. While marveling at Carolyn Chen’s fine scholarship on Taiwanese immigrants’ conversion experience, this review offers a critical reading of Chen’s equation: becoming American = becoming religious or vice versa with the reviewer’s own experience as both an Asian immigrant and a cultural anthropologist. It also discusses Chen’s assessment of the gendered identity of both Asian-American men and women, be it religious, cultural, or political.     

Higher-order factors of the Big Five predict exploration and threat in life stories

Research has not previously examined whether higher-order traits of the Big Five are related to characteristics of life story narratives. The current study explored possible links between the broad dispositions of Stability (comprising the shared aspects of Agreeableness, Conscientiousness, and Emotional Stability) and Plasticity (comprising the shared aspects of Extraversion and Openness) with narrative accounts of threat and exploration in the life-stories of 128 adults. Stability was inversely related to construals of threat in narratives, and Plasticity was positively related to exploration in narratives after controlling for the suppressor effects of demographic variables. These findings add to the research linking higher-order factors of the Big-Five to important domains as well as research linking dispositional traits to narrative identity.
