返回抑制过程中情绪面孔加工优先：ERPs研究

返回抑制(IOR)是指注意过程中个体对已搜索过的位置进行抑制, 从而在随后该位置上出现目标时发生注意重新定向或反应变慢的过程。本研究使用ERPs技术, 采用线索-靶子范式, 考察了情绪目标辨别任务中IOR的发生过程及二者的神经机制。结果发现, 与无效线索相比, 有效线索下的P1波幅更小, N1波幅更大, 正性、负性面孔N170的波幅比中性面孔大。表明当要求被试做情绪辨别任务时, IOR与对情绪信息的反应之间发生了分离, 表现出情绪加工的优先。这说明IOR和情绪偏向是发生在两种不同神经通路上的适应机制, 也为进一步探究注意与情绪的关系问题提供了来自神经电生理学的证据。

Violence Exposure and PTSD Among Delinquent Girls

Summary

This study focuses on the unique trauma histories of incarcerated girls. In particular, this study draws upon data obtained from 100 incarcerated adolescent girls, highlighting areas of similarity to and difference from incarcerated boys, including: overall levels of traumatic violence exposure, exposure to unique forms of traumatic violence, psychological symptomatology, and hypothesized trajectories of involvement in serious delinquent activity. In addition, a case example is presented to illustrate our hypotheses about the trajectories of adolescent girls' involvement in serious delinquent behavior, as well as the prominent role of early trauma histories and repeat victimization in these trajectories.     

Visual memory for feature bindings: The disruptive effect of responding to new perceptual input

In the current study, we examined how short-term memory for location–identity feature bindings is influenced by subsequent cognitive and perceptual processing demands. Previous work has shown that memory performance for feature bindings can be disrupted by the presentation of subsequent visual information, particularly when this information is similar to that held in memory. The present study demonstrates that memory performance for feature bindings can be profoundly disrupted by also requiring a response to visual information presented subsequent to the visual memory array. Across five experiments, memory for a location–identity binding was substantially impaired following a localization response to a following item that matched the location but mismatched the identity of the memory target. The results point to an important role for action in the episodic integration processes that control short-term visual memory performance.     

Predicting dating behavior from aggression and self‐perceived social status in adolescence

We investigated the longitudinal associations between self‐reported aggression, self‐perceived social status, and dating in adolescence using an intrasexual competition theoretical framework. Participants consisted of 536 students in Grade 9 (age 15), recruited from a community sample, who were assessed on a yearly basis until they were in Grade 11 (age 17). Adolescents self‐reported their use of direct and indirect aggression, social status, and number of dating partners. A cross‐lagged panel model that controlled for within‐time covariance and across‐time stability while examining cross‐lagged pathways was used to analyze the data. The findings revealed that direct aggression did not predict dating behavior and was negatively associated with self‐perceived social status in Grade 10. Self‐perceived social status in Grade 9 was positively associated with greater use of indirect aggression in Grade 10. Regarding dating, in Grade 9, self‐perceived social status positively predicted more dating partners the following year, while in Grade 10, it was higher levels of indirect aggression that predicted greater dating activity the following year. Overall, there were no significant sex differences in the model. The study supports the utility of evolutionary psychological theory in explaining peer aggression, and suggests that although social status can increase dating opportunities, as adolescents mature, indirect aggression becomes the most successful and strategic means of competing intrasexually and gaining mating advantages.

     

Infants discriminate manners and paths in non-linguistic dynamic events

Do 14- to 17-month-olds notice the paths and manners of motion events? English- and Spanish-learning infants were habituated to an animated motion event including a manner (e.g., spinning) and a path (e.g., over). They were then tested on four types of events that changed either the manner, the path, both, or neither component. Both English- and Spanish-learning infants attended to changes of manner and changes of path. Thus, infants from two different language communities proved sensitive to components of events that undergird relational term learning.     

Indirect cueing elicits distinct types of autobiographical event representations

Studies that distinguish among believed memories, believed-not-remembered events (e.g., family stories), and nonbelieved memories (i.e., memories no longer believed to have occurred) typically rely on experimenter provided or overtly elicited events. These methods may mis-estimate the frequency and nature of such events in everyday memory. Three studies examined whether such events would be elicited via indirect cueing. Participants recalled and rated events on autobiographical belief, recollection, and other characteristics associated with remembering. All three event types resulted, but with a low rate of nonbelieved memories. Believed and nonbelieved memories received similar perceptual and re-experiencing ratings, and both exceeded believed-not-remembered events. Lifespan cueing found nonbelieved memories to be most frequent in middle childhood (ages 6–11). Cueing for “events” vs. “memories” revealed that “memory” cues lead to retrieval of a more homogeneous set of events and differences when predicting autobiographical belief and recollection. These studies support the distinction between autobiographical belief and recollection for autobiographical events.
