报告题目：Electrophysiological evidence for the effects of unitization on associative recognition memory in older adults
Normal aging is associated with greater declines in associative memory relative to item memory, which may result from impaired recollection. It has been demonstrated recently that familiarity may also contribute to associative recognition when stimuli are perceived as a ‘unitized’ representation. Owing to an understanding that familiarity is relatively preserved in older adults, we explored whether aging-related associative memory deficits could be attenuated when encoded associations were unitized. Retrieval processes associated with familiarity and recollection were measured using event-related potentials (ERPs). In an associative recognition task, 25 young and 24 older adults studied Chinese language two-character compound words and unrelated word pairs. Subsequently, participants were asked to decide whether a presented character pair was intact, rearranged, or new relative to the studied character pairs while electroencephalograms (EEGs) were recorded. Behavioral results showed that age differences were smaller for associative recognition of compound words than for unrelated word pairs. Electrophysiological results indicated that only compounds evoked early frontal old/new effect, and left parietal old/new effect is greater for compounds than for unrelated word pairs in older adults. Mid-frontal, left parietal, and late right frontal old/new effects for compound words, but not for unrelated word pairs, showed no age differences. These findings suggest that unitization could alleviate age-related associative deficits through enhanced familiarity and recollection-based retrieval processes during associative recognition in older adults.
报告题目：Facial reactions to situations of other's real-life pain
报告摘要： Empathy, a basic social cognitive function, plays a vital role in everyone's daily life. A growing body of research reveals that people mimic the emotional facial expression in the context of emotional empathy, e.g., facial expression of anger and happiness elicit corresponding frowns and smiles. There is a dearth of studies examining the facial behaviors in empathy for pain, however. The present study focused on the expression changes as empathic reaction towards situations of other's real-life pain. Highly ecological validity video clips were prerecorded depicting people being injected (n=10, 4 males). The control video clips were recorded from additional 10 subjects showing neutral expressions with arms being wiped by a Q-tip. Thirty-four graduate and undergraduate subjects (males 11, age 20.9±2.2) participated in this experiment. Facial electromyography (EMG), electrodermal activity (EDA) and pulse rate were recorded to assess the emotional responses elicited by visual stimuli. Subjective ratings of pain intensity and unpleasantness as well as interpersonal reactivity index (IRI) were measured after the termination of video stimuli. The results showed that, compared to the neutral videos, viewing pain videos elicited more corrugator activity and more zygomaticus activity as well. The activities of these facial muscles have consistently been attributed to the facial expression of pain. Furthermore, corrugators activity correlated positively to scores of empathic concern subscale of IRI, while zygomaticus activity correlated negatively to IRI scores. These results suggest that observing others in pain may lead to painful facial expression of the observer, and people with higher trait empathy are more facially reactive to others’ suffering.

Evidence from a large cohort of first-episode schizophrenia
Backgrounds: Prospective memory (PM), the ability to remember to carry out intended action in the future, is a complex cognitive function. Empirical evidence suggests that PM deficits exist in chronic schizophrenia. However, previous PM studies in first-episode schizophrenia showed inconsistent results as to whether PM deficits exist independently from other neuropsychological deficits, and were limited to small inpatient samples. We aimed to clarify the nature and extent of PM deficits, using a large first-episode sample.
Methods: Participants were 91 clinically stable outpatients with first-episode schizophrenia and 83 healthy individuals. PM was assessed by both the subjective self-reported checklist and a laboratory-based task capturing time-, event-, and activity-based PM. A set of battery assessing verbal, visuo-spatial, and working memory, and executive functions was also administered to all the participants. Analysis of covariance (ANCOVA) was conducted to examine group difference in PM and to control from other neuropsychological functions. Stepwise linear regression was used to identify neuropsychological functions that predict PM performance in first-episode patients.
Results: Patients with first-episode schizophrenia were impaired in both time- and event-based PM but not activity-based PM, after controlling for IQ and other neuropsychological deficits. Regression modeling suggested that cognitive flexibility predicts time- and event-based PM; working memory predicts event-based PM; whereas age predicts activity-based PM.
Conclusion: Our results convincingly suggest that time- and event-based PM deficits in first-episode schizophrenia are severe and not attributable to other neuropsychological deficits. PM, as a primary deficit, may constitute a neuropsychological marker of schizophrenia.
