Visual Information Processing Speed in Hypnotized and Nonhypnotized Subjects

Using a backward-masking paradigm with a bias-free and ceiling-free psychophysical task, we tested hypnotized and control subjects for speed of visual information processing. Approximately half of each group received visual imagery suggestions in an attempt to influence attention. Imagery produced no significant differential effect. Although an absence of a hypnotizability-performance relationship was in keeping with findings of a previous study, those subjects in the present study who performed under hypnosis were, as a group, significantly superior to the other subjects in speed of information processing.     

Using Score Equating and Measurement Invariance to Examine the Flynn Effect in the Wechsler Adult Intelligence Scale

The Flynn effect (FE; i.e., increase in mean IQ scores over time) is commonly viewed as reflecting population shifts in intelligence, despite the fact that most FE studies have not investigated the assumption of score comparability. Consequently, the extent to which these mean differences in IQ scores reflect population shifts in cognitive abilities versus changes in the instruments used to measure these abilities is unclear. In this study, we used modern psychometric tools to examine the FE. First, we equated raw scores for each common subtest to be on the same scale across instruments. This enabled the combination of scores from all three instruments into one of 13 age groups before converting raw scores into Z scores. Second, using age-based standardized scores for standardization samples, we examined measurement invariance across the second (revised), third, and fourth editions of the Wechsler Adult Intelligence Scale. Results indicate that while scores were equivalent across the third and fourth editions, they were not equivalent across the second and third editions. Results suggest that there is some evidence for an increase in intelligence, but also call into question many published FE findings as presuming the instruments' scores are invariant when this assumption is not warranted.     

表达性写作应用于社会灾难时期心理救援的理论探讨

疫情等社会灾难时期, 创伤经历者急剧增加, 加之交通阻断, 传统的心理救援很难及时应对大范围的灾民心理危机; 而表达性写作便于心理学工作者大规模实施, 且可通过电话、网络等远程通讯工具进行指导, 治疗PTSD等心理创伤, 改善生理、心理健康。社会灾难时期表达性写作的机制复杂, 涉及暴露脱敏、意义重建、自我抽离—自我调节、工作记忆优化和认知神经机制正常化; 其疗效受到作者特质、干预时间和写作形式等潜在因素的影响。相应地, 未来应结合本土社会文化因素, 重视在线干预研究, 探索表达性写作相关的认知神经机制, 综合不同的生理、心理健康指标评估表达性写作的疗效。     

成人依恋与心理理论的关系:认知融合与经验性回避的中介作用

为探究成人依恋、认知融合、经验性回避与心理理论的关系及其作用机制,研究者采用实验法和问卷法对312名成年人进行了测量。研究结果表明：（1）不安全的成人依恋负向预测心理理论;（2）经验性回避在成人依恋与心理理论之间起中介作用;（3）认知融合在成人依恋与心理理论之间不存在中介作用;（4）成人依恋的两种类型（依恋回避、依恋焦虑）呈现出不同的链式中介作用：认知融合与经验性回避在依恋回避与心理理论之间起部分中介作用,而在依恋焦虑与心理理论之间起完全中介作用。研究从心理灵活性的角度考察成人依恋与心理理论的关系及其作用机制,并探究接纳承诺训练在提升社会认知能力上的实践意义。     

Parents' Empathic Responses and Pain and Distress in Pediatric Patients

We investigated the relationship between parents' empathic responses prior to their children undergoing cancer treatment procedures and children's pain/distress during the procedures. We hypothesized: (1) parents' empathic distress would be positively associated with children's pain/distress, (2) parents' empathic concern would be negatively associated with children's pain/distress; and (3) parents' enduring dispositions and social support would be associated with their empathic responses. Parents completed: (1) measures of dispositions and perceived social support several weeks before their children underwent the procedures, and (2) state measures of empathic distress and empathic concern just before the procedures. Empathic distress was positively associated with children's pain; empathic concern was negatively associated with children's pain/distress. Predictions about dispositions and social support were also substantially confirmed.     

前瞻记忆的理论模型综述

前瞻记忆是相对于回溯记忆提出的一种特殊的长时记忆,是指记住在将来某个恰当的时间执行先前意向的行为。本文介绍了近年来研究者提出的前瞻记忆认知和提取机制的理论模型,并对其做了评述。最后,本文针对目前研究中的薄弱环节尝试性地提出了今后前瞻记忆研究进一步发展的方向。

Illness intrusiveness and quality of life in end-stage renal disease: comparison and stability across treatment modalities

Investigated the degree to which chronic, life-threatening illness and its treatment interfere with continued involvements in valued activities and interests--that is, illness intrusiveness--and its impact on quality of life in end-stage renal disease. Data were collected on two occasions separated by a lag of 6 weeks. Mixed analyses of variance indicated that life domains were affected differentially across treatments. Perceived illness intrusiveness correlated significantly with treatment time requirements, uremic symptoms, intercurrent nonrenal illnesses, fatigue, and difficulties in daily activities. Significant quality-of-life differences were observed across treatment modalities for satisfaction/happiness and pessimism/illness-related concerns but not for depression/distress. Perceived illness intrusiveness correlated significantly with each of these quality-of-life measures. Results were stable over time. These findings substantiate the construct of illness intrusiveness as a mediator of the psychosocial impact of chronic, life-threatening illness.
