Quantifying Intervention Intensity: A Systematic Approach to Evaluating Student Response to Increasing Intervention Frequency

Response to intervention (RTI) has been discussed as a new model of assessment. Although the basic process by which RTI works has received frequent attention in the literature, the available research leaves several important questions unanswered (Kavale et al. in Learn Disabil Q 28(1): 2–16, 2005). One concept within RTI that has received little empirical consideration is intervention intensity. The purpose of this study was to evaluate the impact of the application of increased intervention frequency on the mathematics performance of students and to evaluate this increased frequency as a systematic means of increasing and quantifying intervention strength. Results indicate that although all students were responsive to the intervention, some participants were sensitive only to more frequent application of the treatment or at more intense levels of treatment. Through this methodology a means of quantifying treatment intensity was also identified and implications for future research are discussed.     

认知重评和表达抑制情绪调节策略的脑网络分析：来自EEG和ERP的证据

本文旨在对认知重评和表达抑制两种常用情绪调节策略的自发脑网络特征及认知神经活动进行深入探讨。研究采集36名在校大学生的静息态和任务态脑电数据, 经过源定位和图论分析发现节点效率与两种情绪调节显著相关的脑区, 以及脑区之间的功能连接。研究结果表明, 在使用认知重评进行情绪调节时会激活前额叶皮质、前扣带回、顶叶、海马旁回和枕叶等多个脑区, 在使用表达抑制进行情绪调节时会激活前额叶皮质、顶叶、海马旁回、枕叶、颞叶和脑岛等多个脑区。因此, 这些脑区的节点效率或功能连接强度可能成为评估个体使用认知重评和表达抑制调节情绪效果的指标。     

Effects of 1 mA and 2 mA transcranial direct current stimulation on working memory performance in healthy participants

Anodal transcranial current stimulation (tDCS) to the left dorsolateral prefrontal cortex (DLPFC) has been shown to enhance working memory (WM) in neuropsychiatric patients. In healthy populations, however, tDCS obtains inconclusive results, mostly due to heterogeneous study and stimulation protocols. Here, we approached these issues by investigating effects of tDCS intensity on simultaneous WM performance with three cognitive loads by directly comparing findings of two double-blind, cross-over, sham-controlled experiments. TDCS was administrated to the left DLPFC at intensity of 1 mA (Experiment 1) or 2 mA (Experiment 2), while participants completed a verbal n-back paradigm (1-, 2-, 3-back). Analysis showed no overall effects of tDCS on WM, but a significant interaction with cognitive load. The present study suggests that cognitive load rather than tDCS intensity could be a decisive factor for effects on WM. Moreover, it emphasizes the need of thorough investigation on study parameters to develop more efficient stimulation protocols.     

A cognitive architecture for modeling emotion dynamics: Intensity estimation from physiological signals

Current approaches to emotion recognition do not address the fact that emotions are dynamic processes. This work concerns itself with the development of a cognitive architecture for modeling the dynamics of emotions with specific focus on a gray-box model for dynamic emotion intensity estimation that can incorporate findings from appraisal models, specifically Scherer’s Component Process Model. It is based on Dynamic Field Theory which allows the combination of theoretical knowledge with data-driven experimental approaches. A user study is conducted applying the proposed model to estimate intensity of negative emotions from physiological signals. Results show significant improvements of the proposed model to common methodology and baselines. The flexible cognitive architecture opens a wide field of experiments and directions to deepen the understanding of emotion processes as a whole.     

Disruptive effects of stimulus intensity on two variations of a temporal discrimination procedure

Previous reports using stimulus intensity changes to disrupt temporal discrimination have shown shifts in the psychophysical curve for time, while studies using other disruptors have shown a flattening of the curve. The current study investigated the impact of increases and decreases in stimulus intensity on temporal discrimination in pigeons, to determine if a flattening of the curve could be extended to this disruptor. The brightness of the sample to be timed was manipulated under two procedural variations, in which the response alternatives were differentiated by color or location. Results showed that all subjects in the color procedure, and one in the location procedure, showed a flattening of the psychophysical curve when they experienced increased stimulus intensity in descending order. No subjects exposed to an ascending order of stimulus intensities, and none of the other subjects in the location procedure, showed any impact of changed stimulus intensity. Minimal disruption was found when test sessions presented decreased stimulus intensity levels in a second series. These results, together with those using other types of disruptors, add to the evidence of a flattening of the psychophysical curve when temporal discrimination is disrupted.     

Gender differs: Modelling knowledge sharing from a perspective of social network ties

The present paper proposes a model of knowledge sharing, in which coworker congruence, outcome interdependence, perceived organizational support, and procedural justice influence knowledge sharing indirectly through the mediation of instrumental ties and expressive ties, and examined gender differences in causal connections within the model. In a sample of employees in Taiwan, it was shown that the influence of instrumental ties on knowledge sharing is stronger for females than for males; the influence of expressive ties on knowledge sharing is stronger for males than for females; the influence of coworker congruence on expressive ties is stronger for females than for males; the influence of outcome interdependence on instrumental ties is stronger for females than for males; and the influence of perceived organizational support on instrumental ties is stronger for males than for females.     

Making the Intangible Tangible: Using Expressive Art During Termination to Co-Construct Meaning

In this article, a creative termination activity grounded in relational-cultural theory is presented. In addition to providing a means for summarizing the counseling experience, this activity promotes relational development in the midst of client termination. Following implementation of the activity, the client and counselor are provided tangible, co-constructed gifts that are symbolic of the therapeutic relationship and relational growth. The authors provide a rationale for how this intervention promotes self-awareness, outline directions for implementation, and provide a case illustration to demonstrate how counselors can help promote relational closure and solidify clients’ therapeutic gains.     

Alexithymia and Affect Intensity of Fine Artists

Research on creative artists has examined mainly their personality traits or cognitive abilities. However, it seems important to explore also their emotional traits to complete the profile. This study examines two emotional characteristics: alexithymia and affect intensity. Even if most research suggests that artists are less alexithymic and experience more intensively their emotions, Botella, M., Zenasni, F., and Lubart, T. (Psychology of Aesthetics, Creativity, and the Arts, 5 , 251, 2011) observed that art students were as alexithymic as psychology students and more alexithymic than a normative population. The aim of this study was to examine these issues with artists and non‐artists and to compare artists to art students. Results indicate that artists are less alexithymic and present higher affect intensity than non‐artists. Moreover, results show that art students present more difficulties processing their emotions than artists.     

Why Seemingly Trivial Events Sometimes Evoke Strong Emotional Reactions: The Role of Social Exchange Rule Violations

People sometimes display strong emotional reactions to events that appear disproportionate to the tangible magnitude of the event. Although previous work has addressed the role that perceived disrespect and unfairness have on such reactions, this study examined the role of perceived social exchange rule violations more broadly. Participants (N = 179) rated the effects of another person’s behavior on important personal outcomes, the degree to which the other person had violated fundamental rules of social exchange, and their reactions to the event. Results showed that perceptions of social exchange rule violations accounted for more variance in participants’ reactions than the tangible consequences of the event. The findings support the hypothesis that responses that appear disproportionate to the seriousness of the eliciting event are often fueled by perceived rule violations that may not be obvious to others.
