记忆训练对改善少年、青年和老年人认知功能的作用

本工作采用“位置法”(method of loci)对24例少年、24例青年和22例老年被试进行了记忆训练研究。以毕生发展的观点比较认知训练对改善不同年龄人记忆的作用,进而探讨发展的认知功能储备能量的年龄差异和训练的迁移效应。结果表明认知干预措施可在一定程度上改善老年人的记忆,同时也显示了在发展的储能和对图形的迁移效应方面,老年人明显不如青、少年,而青年与少年则彼此相近。     

Assessing the relationship of Type A beliefs to cardiovascular disease risk and psychosocial distress

Investigators have begun to take a multimodal approach to the assessment and treatment of psychosocial risk factors for cardiovascular disease (CVD). For instance, cognitive responses have become the focus of contemporary research along with continued examination of overt Type A behaviors. Price (1982) has outlined a set of beliefs purportedly associated with Type A behavior and subsequent CVD risk. The current study examines the validity of this belief set as represented by a newly developed measure, the Type A Cognitive Questionnaire (TACQ). Subjects were 221 employed adults participating in a worksite CVD risk reduction program. They completed the TACQ as part of a pretreatment CVD risk screening protocol. As hypothesized, TACQ scores were significantly associated with Type A behavior, hostility, physiological mediators of CVD, and psychosocial distress. Discussion addresses continued refinement of the Type A belief construct.     

Competitive fixed-interval performance in humans

Two persons responded in the same session in separate cubicles, but under a single schedule of reinforcement. Each time reinforcement was programmed, only the first response to occur, that is, the response of only one of the subjects, was reinforced. “Competitive” behavior that developed under these conditions was examined in three experiments. In Experiment 1 subjects responded under fixed-interval (FI) 30-s, 60-s, and 90-s schedules of reinforcement. Under the competition condition, relative to baseline conditions, the response rates were higher and the pattern was “break-and-run.” In Experiment 2, subjects were exposed first to a conventional FI schedule and then to an FI competition schedule. Next, they were trained to respond under either a differential-reinforcement-of-low-rate (DRL) or fixed-ratio (FR) schedule, and finally, the initial FI competition condition was reinstated. In this second exposure to the FI competition procedure, DRL subjects responded at lower rates than were emitted during the initial exposure to that condition and FR subjects responded at higher rates. For all subjects, however, responding gradually returned to the break-and-run pattern that had occurred during the first FI competition condition. Experiment 3 assessed potential variables contributing to the effects of the competitive FI contingencies during Experiments 1 and 2. Subjects were exposed to FI schedules where (a) probability of reinforcement at completion of each fixed interval was varied, or (b) a limited hold was in effect for reinforcement. Only under the limited hold was responding similar to that observed in previous experiments.     

Typical coping patterns: A person-centered approach to coping

Applying the person-oriented approach to coping can provide a unique perspective by revealing typical latent patterns. The study examined typical latent patterns shown by task-, emotion- and avoidance-oriented trait-based coping styles. We performed secondary analyses with Latent Profile Analysis on our former data and three independent datasets containing coping measures with the CISS-48 scale (Endler & Parker, 1994). Gender differences were also studied. Two basic profiles seem universal: the first is characterized by a high level of task-oriented coping, and the second profile is with moderately high scores on all three coping styles. The finding indicates that two fundamental latent coping profiles exist, which suggests a within-subject comparison in practice instead of investigating the absolute value of coping styles. Comparing data before and after 2020, COVID-19 does not seem to affect these profiles. The person-centered approach provides a possibility for the integration of coping-related findings.     

依恋对象回应方式对不同依恋类型幼儿支持提供预期修正的影响

依恋对象的敏感性回应是儿童安全依恋发展的重要前因。研究采用改编版依恋预期范式考察实时互动情境中依恋对象确定性和概率性回应对幼儿支持提供预期及预期修正的影响。结果发现：相对不安全型依恋幼儿,初始预期中安全型幼儿更多预期依恋对象会向依恋者提供支持;幼儿能够基于依恋对象的确定性和概率性回应一致地修正对该对象是否提供支持的预期。同时,低水平回应对幼儿预期修正的影响高于高水平回应。研究表明5岁左右幼儿能够基于实时互动中依恋对象的回应信息修正其对该依恋对象的预期,这对理解幼儿依恋表征的发展具有重要启示。     

Family mental health during the COVID-19 pandemic: Changes in parent-adolescent internalizing symptoms in the United States

The current paper examined the temporal linkage of internalizing symptoms among parent-adolescent dyads during the beginning of the COVID-19 pandemic, and whether COVID-19-related concerns were associated with parent-adolescent linkage of symptoms. Using a 5-week survey-based study, parent-adolescent dyads filled out weekly surveys measuring COVID-19 concerns and internalizing symptoms. Parent and adolescent depressive symptoms did not change over time; however, adolescents experienced decreases in anxiety. Parent-adolescent dyads exhibited linkage in depressive symptoms but not anxiety symptoms. However, linkage in anxiety symptoms varied by parent's COVID-related stress. Study findings provide insight into how COVID-19 disruptions impacted family well-being during adolescence.     

A Comparison of Active Student Response and On-Task Instruction on the Acquisition and Maintenance of Health Facts by Fourth Grade Special Education Students

An alternating treatments design was used to compare the effects of active student response (ASR) and on-task (OT) instruction on the acquisition and maintenance of health facts during small-group lessons. Five students with learning difficulties (4 students identified as developmentally handicapped and 1 student identified as learning disabled) participated in daily instruction on weekly sets of 20 unknown health facts (10 facts assigned to the ASR condition and 10 to the OT condition). During ASR instruction, the teacher modeled the correct response to a health question that was presented visually on a health fact card, and the students immediately repeated the correct response in unison three times. During OT instruction, students attended visually to the health fact card as the teacher modeled the correct response. All 5 students made more correct responses on end-of-day tests on health facts taught with ASR instruction than they did on health facts taught with OT instruction. ASR instruction also produced consistently superior results on maintenance tests administered 2 weeks after instruction.     

8─11个月婴儿迂回行为发展特点与学习能力的研究

采用程序标准化的婴儿迂回行为测验,探讨了２４４名８－１１个月婴儿的迂回行为发展特点及学习能力。结果表明：（１）８－１１个月婴儿的迂回行为水平表现出随婴儿月龄的增长而提高的趋势。（２）８－１１个月的婴儿具有从反复尝试中学会迂回行为的可能性,其中９、１０个月的婴儿的学习可能性较大,而８个月婴儿的学习可能性较小。（３）８－１１个月婴儿的学习速度随月龄增大而提高。
