Soft constraints in interactive behavior: the case of ignoring perfect knowledge in-the-world for imperfect knowledge in-the-head

Constraints and dependencies among the elements of embodied cognition form patterns or microstrategies of interactive behavior. Hard constraints determine which microstrategies are possible. Soft constraints determine which of the possible microstrategies are most likely to be selected. When selection is non-deliberate or automatic the least effort microstrategy is chosen. In calculating the effort required to execute a microstrategy each of the three types of operations, memory retrieval, perception, and action, are given equal weight; that is, perceptual-motor activity does not have a privileged status with respect to memory. Soft constraints can work contrary to the designer’s intentions by making the access of perfect knowledge in-the-world more effortful than the access of imperfect knowledge in-the-head. These implications of soft constraints are tested in two experiments. In experiment 1 we varied the perceptual-motor effort of accessing knowledge in-the-world as well as the effort of retrieving items from memory. In experiment 2 we replicated one of the experiment 1 conditions to collect eye movement data. The results suggest that milliseconds matter. Soft constraints lead to a reliance on knowledge in-the-head even when the absolute difference in perceptual-motor versus memory retrieval effort is small, and even when relying on memory leads to a higher error rate and lower performance. We discuss the implications of soft constraints for routine interactive behavior, accounts of embodied cognition, and tool and interface design.

早期双语儿童第二语言的词汇概念组织

该文通过两个实验考察早期双语儿童第二语言的词汇概念组织。实验1运用跨语言重复启动的范式,结果发现了跨语言重复启动效应,说明早期双语儿童可以直接通达概念意义,但是二语词汇语义通达的强度要弱于一语词汇语义通达的强度。在实验1的基础上,实验2运用图片命名的范式,结果发现了命名的语言效应,进一步说明早期双语儿童二语词汇与概念表征的联系要弱于一语词汇与概念表征的联系。总的实验结果表明,早期双语儿童在记忆表征中建立了二语词汇与概念表征的直接联系,其第二语言的词汇概念组织在本质上是机能性的。     

Skin picking in patients with obesity: Associations with impulsiveness and self‐harm

Previous studies suggest elevated prevalence rates of skin picking and self‐harm in patients with obesity compared to individuals in the general population. Hence, further studies should investigate prevalence rates and correlates of skin picking in this population – especially its differentiation to self‐harm. Skin picking and obesity are both associated with specific facets of impulsiveness. This relation should be explored to shed light on potentially shared mechanisms in etiology. Therefore, the present study examined the occurrence of skin picking and its associations with impulsiveness and self‐harm in a sample of pre‐bariatric surgery patients with obesity class II/III. Within the routine preoperative psychiatric evaluation, a total of 139 bariatric surgery candidates (78% female, BMI range 35–69) completed a self‐report questionnaire assessing sociodemographic variables, anxiety, depression, self‐harm, impulsiveness, and skin picking severity (urges: frequency, intensity, controllability; behavior: frequency, intensity, controllability; resistance, emotional distress, impairment, and avoidance). Ten participants (7.2% of the sample) reported recurrent skin picking leading to skin damage, repeated attempts to decrease skin picking, and psychosocial impairment (emotional distress, impairment in functional areas, avoidance) due to skin picking. In line with previous findings, skin picking severity shows a medium correlation with attentional impulsiveness. The majority of self‐harm types were not associated with skin picking severity. The current study reveals a high occurrence of skin picking compared to the general population. The results indicate an association between skin picking severity and attentional impulsiveness. Further research is needed to investigate the differentiation of skin picking and self‐harm in more detail.     

Like a phoenix: the journey toward core-self restoration following paediatric skin-burn injury: a psychoanalytic perspective

Severe and sudden injury to the skin during childhood may damage both the child’s outer appearance and mental state. Such a trauma can provoke a complete and utter breakdown of the core-self and regression to an ‘unintegrated’ state. We present the case of 11-year-old Michael, who played with matches, set a fire and sustained severe burn trauma. Michael was treated in our rehabilitation ward over several months and received skin treatment, physical therapy and psychotherapy. Paediatric burn injury is not only a physical struggle but is often accompanied by intense emotional distress of the child and his family. In describing Michael’s therapeutic process, we show how the restoration of the core-self, alongside the healing of the outer skin, provoke issues concerning early infantile skin formation, normative age-related conflicts and vulnerabilities specific to the child. By integrating psychoanalytic thinking into the clinical work of skin rehabilitation, following burn injury, we demonstrate how the significant relationship between the skin and the self manifest in different practice.     

不同归因方式的诱导对自尊不同学生失败后测验成绩的影响

采用2×2两因素被试间设计检验了不同归因方式的诱导对自尊不同学生失败后测验成绩的影响。结果表明:(1)总体上,高自尊组在失败后的测验成绩显著优于低自尊组;(2)内部归因后,高自尊组的后继测验成绩非常显著地优于低自尊组;外部归因后,高、低自尊组的后继测验成绩无显著差异;(3)对于高自尊组,内部归因后的后继测验成绩优于外部归因后的成绩,但未达到显著性水平;对于低自尊组,外部归因后的成绩显著优于内部归因后的成绩。     

广东汕头市公安人员心理健康水平调查研究

为调查了解汕头市公安人员的心理健康状况．本文采用心理症状自评量表(SCL-90)对汕头市区分局的男女警察共339名进行问卷调查,分析所得数据,结果发现：样本总体健康水平高于常模;女警察心理健康程度略高于男警察;治安警在强迫人际关系和忧郁程度方面因子分显著比刑警、巡警高;警龄大于15年的警察群体的躯体化因子分大于警龄小于15年的警察;年龄大的警察样本偏执因子分高于年龄小的样本。结论表明：警察群体的总体心理健康状况良好,但部分群体在某些心理状况方面需加以调整和改善。     

母亲社会情绪行为的相关因素研究

本研究考察了婴儿情绪特征、母亲受教育程度和母亲社会情绪行为的关系。结果表明：（1）情绪特征不同婴儿的在积极社会情绪行为上无显著差异,而在消极情绪行为上,负性情绪组婴儿的显著地少于负性情绪组婴儿的母亲;（2）受教育程度不同的在积极情绪行为上无显著差异,而在消极情绪行为上,受教育程度高的母亲显著地少于受教育程度低的母亲;（3）综合考察婴儿情绪特征和母亲受教育程度两方面因素,受教育程度在大专以下、负性情绪较多婴儿的母亲在积极情绪行为上与其他组的母亲无任何差异,而其消极情绪行为显著地多于其他组的母亲。

Within-individual relations of emotional,social, and work self-efficacy beliefs to organizational citizenship behaviors

Organizational citizenship behaviors (OCBs) represent a specific class of prosocial behaviors observable in the organizational environment. This study examined the longitudinal relations among regulatory emotional, social and work self-efficacy beliefs, and their relations to Organizational Citizenship Behaviors directed at specific individuals (OCBIs) at work, using a Latent State-Trait Model with Autoregressive effects (LST-A). The LST-A decomposes variance into trait, autoregressive, and occasion-related components, and allowed for testing of all hypotheses at the within-worker level. The model was tested using longitudinal data from N = 562 italian workers. Results supported the hypotheses that both social and work self-efficacy fully mediated the longitudinal relations between regulatory emotional self-efficacy in managing negative emotions at work and OCBIs. Theoretical and practical contributions of the findings are discussed.
