前瞻记忆老化研究综述

前瞻记忆的老化现象是指相对于年轻人,老年人的前瞻记忆水平有所下降。本文分别对在自然情景、实验室情景以及模拟情景条件下的前瞻记忆老化研究进行探讨和分析,并总结和阐述了当前几个主要的前瞻记忆老化理论及模型。     

自主创新的心理发生机制研究

自主创新是社会、自然和人类自身的发展变化,与一个国家或企业原有发展水平之间的矛盾所产生的创新需要向个体身上转化,与个体自我实现的需要相互作用而产生的。一般经过创新需要的形成、转化、现实化,再由创新需要转化为创新动机而引发。可分为有意自主创新和无意自主创新两种类型。

Openness to Experience and Team Creativity: Effects of Knowledge Sharing and Transformational Leadership

This study extends the research on the creative work process in teams by integrating personality traits, knowledge-sharing behavior, and transformational leadership. Analyses of multisource data from 347 members of 53 creative teams in 26 firms reveal the associations between heterogeneity of openness to experience in teams and team creativity (i.e., idea generation and idea development). Further, knowledge sharing mediated the relationships between personality heterogeneity and team creativity. Transformational leadership amplified the relationship between personality heterogeneity and idea development. Theoretical and practical implications are discussed.     

Will recalling a purchase increase your well‐being? The sequential mediating roles of postpurchase sharing and relatedness need satisfaction

To shed light on the underlying mechanisms of the relationship between purchase type and well‐being (including hedonic and eudaimonic well‐being), this study explored the mediating roles of both postpurchase sharing and relatedness need satisfaction in a Chinese sample. In the current study, participants were required to recall an impressive past purchase and report the level of postpurchase sharing, relatedness need satisfaction, and well‐being experienced after the purchase. The results indicated that (a) participants in the experiential purchase group reported higher levels of both hedonic and eudaimonic well‐being than did those in the material purchase group, and (b) postpurchase sharing and relatedness need satisfaction sequentially mediated the relationship between purchase type and well‐being. Specifically, individuals were more willing to share with others after experiential purchases than after material ones. Therefore, in turn, they experienced higher levels of relatedness need satisfaction, which was conducive to higher levels of both hedonic and eudaimonic well‐being.     

Durability of Cognitive Behavioral Therapy Effects for Youth and Adolescents With Anxiety,Depression, or Traumatic Stress:A Meta-Analysis on Long-Term Follow-Ups

Cognitive behavioral therapies (CBT) for youth with anxiety, traumatic stress, and depression have demonstrated strong effects in individual studies and meta-analyses. Relatively more attention has been given to posttreatment effects, though, and assessment of follow-up effects has been limited at the meta-analytic level. The current meta-analysis aimed to (a) examine the effects of youth CBT at posttreatment, 1-month, 3-month, 6-month, 1-year, and long-term (2 + years) follow-up as well as (b) identify research-related variables (e.g., measure respondent type) that relate to effects. Using a random effects model across 110 child and adolescent CBT groups, within-group effect sizes were large at posttreatment (g = 1.24) and from 1-month through long-term follow-up (g = 1.23–1.82), and effect sizes did not significantly differ by treatment target (i.e., anxiety, traumatic stress, depression). However, availability of outcome data for effect sizes diminished across later follow-up assessments. Moreover, effect sizes were significantly associated with outcome respondent type across assessment timing, with outcome measures from caregiver and youth respondents associated with smaller effect sizes (B = -0.97, p < 0.001) relative to outcome measures that were evaluator-reported. Results provide initial support for the durability of treatment effects for youth CBTs and highlight the importance of some confounding variables. Implications for improving treatment research standards and prioritizing assessment of long-term follow-up assessment are discussed.     

Finger inter-dependence: linking the kinetic and kinematic variables

We studied the dependence between voluntary motion of a finger and pressing forces produced by the tips of other fingers of the hand. Participants moved one of the fingers (task finger) of the right hand trying to follow a cyclic, ramp-like flexion-extension template at different frequencies. The other fingers (slave fingers) were restricted from moving; their flexion forces were recorded and analyzed. Index finger motion caused the smallest force production by the slave fingers. Larger forces were produced by the neighbors of the task finger; these forces showed strong modulation over the range of motion of the task finger. The enslaved forces were higher during the flexion phase of the movement cycle as compared to the extension phase. The index of enslaving expressed in N/rad was higher when the task finger moved through the more flexed postures. The dependence of enslaving on both range and direction of task finger motion poses problems for methods of analysis of finger coordination based on an assumption of universal matrices of finger interdependence.     

A hierarchical process-dissociation model

In fitting the process-dissociation model (L. L. Jacoby, 1991) to observed data, researchers aggregate outcomes across participant, items, or both. T. Curran and D. L. Hintzman (1995) demonstrated how biases from aggregation may lead to artifactual support for the model. The authors develop a hierarchical process-dissociation model that does not require aggregation for analysis. Most importantly, the Curran and Hintzman critique does not hold for this model. Model analysis provides for support of process dissociation--selective influence holds, and there is a dissociation in correlation patterns among participants and items. Items that are better recollected also elicit higher automatic activation. There is no correlation, however, across participants; that is, participants with higher recollection have no increased tendency toward automatic activation. The critique of aggregation is not limited to process dissociation. Aggregation distorts analysis in many nonlinear models, including signal detection, multinomial processing tree models, and strength models. Hierarchical modeling serves as a general solution for accurately fitting these psychological-processing models to data.
