How did I remember to do that? Self-reported strategy use for laboratory prospective memory tasks

ABSTRACT

The role of metacognition in prospective memory (PM) has received relatively little attention. This study combined data from several experiments to identify the strategy repertoire employed during a classic laboratory PM task and to determine whether self-reported strategy was related to performance. Participants (N?=?668) completed either a focal or nonfocal PM task embedded in an ongoing lexical decision task. The results indicated that participants reported the same strategy repertoire regardless of PM task focality. Participants who reported using a strategy performed better than those who did not report using one, and this was especially true under nonfocal conditions. Self-reported strategy use was also associated with more cost to the ongoing task when the opportunity to complete the PM task was present. These findings add to what is known about the metacognitive components of PM and underscore the need for additional research in this area.     

学前教育年限与母亲受教育水平对农村一年级 小学生学校适应的影响

研究采用同伴提名法、教师和家长报告法,对农村135名一年级小学生进行了为期一年的追踪调查,在此基础上,考察了学前教育年限、母亲受教育水平与学校适应之间的关系。结果表明:(1)学前教育年限越长,小学生越多地表现出积极社会行为,但这种优势仅体现在小学入学初期;(2)母亲受教育水平越低,小学生越多地表现出敏感退缩行为和受拒绝同伴关系;(3)对于母亲受教育水平较低的小学生,学前教育年限越长,其攻击冒犯行为越多;而对于母亲受教育水平较高的小学生,学前教育年限越长,其攻击冒犯行为越少。可见,母亲受教育水平与学前教育年限相互作用,共同影响儿童发展结果,且母亲受教育水平的影响作用更为明显。

A Case of Synaesthesia

Two experiments employed Potential Performance Theory (PPT) to correct for inconsistency in a speeded task. In Experiment 1, a search task was employed whereby participants searched for a target letter among distracters. In Experiment 2, the search task was more complex and naturalistic—participants searched for enemy weapons in aerial photographs. Not surprisingly, the results revealed that longer search times led to greater accuracy. However, this improvement was due only in part to improved search strategies. Much, if not most, of the improvement was due to increased consistency. The authors demonstrate and discuss some of the advantages to be gained by considering a speeded task within the context of a clear and mathematically precise theory (PPT).     

A Longitudinal Study of Semantic Grouping Strategy Use in 6–11-Year-Old Children: Investigating Developmental Phases,the Role of Working Memory,and Strategy Transfer

This two-cohort longitudinal study on the development of the semantic grouping strategy had three goals. First, the authors examined if 6–7-year-olds are nonstrategic before becoming strategic after prompting at 8–9 years of age, and if 8–9-year-olds are prompted strategic before spontaneous strategy use at 10–11 years of age. Children 6–7 and 8–9 years old performed two sort-recall tasks (one without and one with a grouping prompt) at two time points separated 1.5 years from each other. Second, the authors investigated whether short-term or working memory capacity at time point 1 predicted recall in children who did or did not use the semantic grouping strategy 1.5 years later. Third, the authors investigated whether prompted strategic children and children who used the strategy spontaneously differed in strategy transfer to a new task. Developmental results confirmed previous cross-sectional results, but in a longitudinal two-cohort study 6–7-year-olds were nonstrategic, and became prompted strategic around 8–9 years of age, followed by spontaneous strategy use at age 10–11 years. The authors found that memory capacity was not predictive of later use of the strategy. New findings were that prompted strategic children were as equally able as spontaneously strategic children to transfer the strategy to a new task, albeit with smaller recall benefits.     

Attachment Security,Personality, and Adjustment of Elementary School Children

Children's development is assumed to be closely related to their attachment security and their personality. The authors’ aim was to examine the joint contribution of attachment security and personality traits to children's adjustment by examining diverse children's outcomes (emotional symptoms, social functioning, and behavioral problems) and using various perspectives (children, parents, and teachers). The sample comprised 247 8–12-year-old children from low socioeconomic status neighborhoods. Personality and attachment contribute to the different domains of adjustment. In cases of moderation, attachment security moderates the implications of personality traits on children's adjustment. The findings highlight the contribution of positive personality tendencies in playing down the difficulties of insecurely attached children.     

Family Functioning and Psychological Well-Being,School Adjustment,and Problem Behavior in Chinese Adolescents With and Without Economic Disadvantage

Using an indigenously developed measure of family functioning, the author examined the association between family functioning and adolescent adjustment in 1,519 Chinese adolescents. Results showed that family functioning was significantly related to measures of adolescent psychological well-being (existential well-being, life satisfaction, self-esteem, sense of mastery, general psychiatric morbidity), school adjustment (perceived academic performance, satisfaction with academic performance, and school conduct), and problem behavior (delinquent and substance abuse behavior). Family functioning was generally more strongly related to measures of adolescent adjustment for adolescents with economic disadvantage than for adolescents without economic disadvantage.     

Interplay of Biomechanical Constraints and Kinematic Strategies in Selecting Arm Postures

In this study, the authors examined the interplay between biomechanics and control strategies in the resolution of excess degrees of freedom at the joint level. Seven participants made aimed arm movements from 30 starting points and several starting postures to targets. Final arm postures for movements to a target exhibited substantial joint angle variation. Through regression modeling and by comparing observed final arm postures with biomechanically plausible postures, the authors identified 3 kinematic strategies: (a) Maintain deviations from the average angle at the starting point to the joint's final posture; (b) make torso rotations that are a fixed proportion of shoulder rotations; and (c) adopt a characteristic combination of 4 wrist-positioning approaches. The results demonstrated that kinematic strategies can account for substantial variance in final arm postures, if one takes into account 2 types of individual differences—those that arise inevitably from biomechanical constraints and those that reflect choices in movement strategy.     

Effects of Varying Load Conditions on the Organization of Postural Adjustments during Voluntary Arm Flexion

One purpose of the experiments reported here was to further clarify the effect of varying loads on postural adjustments. Another was to reevaluate whether or not the timing of electromyographic (EMG) activity in the postural muscle is preprogrammed. To accomplish these goals, we compared the effect of the presence or absence of prior knowledge of a load on the timing of EMG activity in the postural muscle (biceps femoris [BF]) with that in the focal muscle (anterior deltoid [AD]). Although the sequence of EMG activation was similar under conditions with and without a load, the timing of postural EMG activities (BFi, ipsilateral BF; BFc, contralateral BF) in associated postural adjustments was dependent on the force of arm movement, and the latencies of postural EMG activities (BFi—BFc) were dependent on the speed of arm movement. This indicates that EMG changes in the upper (focal muscle) and lower limbs (postural muscle) were triggered by different motor programs. Moreover, similar EMG activities were observed in postural muscles when the subject had advance knowledge of the presence or the absence of a load. Thus, this suggests that BFi may be centrally preprogrammed (anticipatory regulation) and BFc may be feedback regulated. Furthermore, environmental information may be a critical source of influence on those postural responses.     

Perspectives of Adults Living With Autism Spectrum Disorder: Psychosocial and Occupational Implications

The incidence of Autism Spectrum Disorder (ASD) has increased over the past decade suggesting a need for further research. This article describes a two phase phenomenological study which explored the lived experience of ASD and its psychosocial effects on relationships, socialization, and occupational participation. Phenomenological interviews were given to three women and three men with high functioning ASD. Phase two of the research included two additional individual interviews and four focus groups. Results indicated themes regarding participants' desires to engage in social occupations, and barriers caused by the nature of the ASD which may successfully be addressed by occupational therapy.
