Gesture for generalization: gesture facilitates flexible learning of words for actions on objects

Verb learning is difficult for children (Gentner, 1982 ), partially because children have a bias to associate a novel verb not only with the action it represents, but also with the object on which it is learned (Kersten & Smith, 2002 ). Here we investigate how well 4‐ and 5‐year‐old children (N = 48) generalize novel verbs for actions on objects after doing or seeing the action (e.g., twisting a knob on an object) or after doing or seeing a gesture for the action (e.g., twisting in the air near an object). We find not only that children generalize more effectively through gesture experience, but also that this ability to generalize persists after a 24‐hour delay.     

Auditory access,language access,and implicit sequence learning in deaf children

Developmental psychology plays a central role in shaping evidence‐based best practices for prelingually deaf children. The Auditory Scaffolding Hypothesis (Conway et al., 2009) asserts that a lack of auditory stimulation in deaf children leads to impoverished implicit sequence learning abilities, measured via an artificial grammar learning (AGL) task. However, prior research is confounded by a lack of both auditory and language input. The current study examines implicit learning in deaf children who were (Deaf native signers) or were not (oral cochlear implant users) exposed to language from birth, and in hearing children, using both AGL and Serial Reaction Time (SRT) tasks. Neither deaf nor hearing children across the three groups show evidence of implicit learning on the AGL task, but all three groups show robust implicit learning on the SRT task. These findings argue against the Auditory Scaffolding Hypothesis, and suggest that implicit sequence learning may be resilient to both auditory and language deprivation, within the tested limits.

Teaching college students to pour accurately using behavioral skills training: Evaluation of the effects of peer modeling

Excessive alcohol consumption among college students is a serious problem. Alcohol education courses, during which students are taught to free‐pour accurate servings of alcohol, have been proposed as one strategy to reduce this problem. However, few studies have evaluated the effects of peer models on free‐pour skill maintenance. We used a nonconcurrent multiple‐baseline across subjects design to assess the effects of peer modeling on maintenance of college students' (N = 19) pouring skills of a standard serving of beer immediately following Behavioral Skills Training (BST). Results indicated participants who inaccurately poured a standard serving of beer at baseline (n = 17) accurately poured following receipt of BST, and all participants (N = 19) maintained accurate pouring in the presence of peer confederate models who poured inaccurately or accurately. Results suggest BST is an efficient (i.e., low to no‐cost, requires no sophisticated laboratory space or software, and makes use of available and affordable materials) and effective tool for teaching college students to pour standard servings of beer and that the immediate introduction of inaccurately pouring peer models has little or no effect on skill maintenance.     

Delay knowledge and trial set count modulate use of proactive versus reactive control: A meta-analytic review

The AX-continuous performance task (AX-CPT) and dot pattern expectancy (DPX) are the predominant cognitive paradigms used to assess the relative utilization of proactive versus reactive cognitive control. Experimental parameters vary widely between studies and systematically between different modalities (i.e., fMRI vs. EEG) with unknown consequences for the implementation of control. This meta-analytic review systematically surveyed these bodies of literature (k = 43, 73 data points) to resolve how cue–probe delay knowledge, delay length, and trial set count modulate the preferential use of proactive versus reactive control. In healthy young adults, delay knowledge and increasing trial set count each bias participants toward greater proactive control. Further, the interaction of delay knowledge and trial set count accounts for ~40% of variability in proactive/reactive control performance. As trial count varies reliably between experimental modalities, it is critical to understand how these parameters activate distinct cognitive processes and tap into different neural mechanisms for control. Subgroup analyses revealed important distinctions from our results in healthy young adults. Healthy, slightly older adults (ages 30–45 years) performed more reactively compared to healthy young adults. In addition, participants with schizophrenia showed evidence of more proactive control as trial set count increased. In light of this meta-analytic review, we conclude that delay knowledge and trial set length are important parameters to account for in the assessment of proactive versus reactive control. More broadly, this metaregression provides strong evidence that cognitive control becomes more reactive when timing demands are not known, and that both healthy persons and persons with schizophrenia shift toward proactive control with increasing repetitions of a task set.     

Time,or the mediation of the now: on Dan Zahavi’s “irrelational” account of self-temporalization

On Dan Zahavi’s Husserlian account of the subject, the self-temporalization of subjectivity presupposes what he calls an “immediate impressional self-manifestation.” It follows from this view that self-awareness is an inherent power of the one who will be subject, rather than a product of sociality introduced into life from without. In this paper, I argue against Zahavi’s position by going over the development of Husserl’s account of time-consciousness, examining the positions Husserl takes and the reasons that he comes to these positions. Once we reach Husserl’s ultimate account, it becomes evident that Zahavi’s position is untenable.     

The West Bank “Alternative Peace Movement” and its transnational infrastructure: a case study in “primordialist universalism”

This article provides an overview and theorization of the “Alternative Peace Movement” (APM), a transnational education and advocacy network based in the West Bank. Emerging in the troubled context of current Israel-diaspora relations and US campus politics, the APM promotes a syncretic Jewish identity narrative and boundary-crossing political programme. Drawing on a content and discourse analysis of the movement’s online documentation, as well as interviews with movement leaders, participants, and allies, the article outlines the APM’s infrastructure and discourse, and provides an historical backdrop and set of theoretical tools for rendering comprehensible the movement’s seeming contradictions and incoherencies. It describes the APM as a case study in “primordialist universalism,” a political orientation that aims to pursue civic and human rights of a universal character by inhabiting a “hard” ethnonational subjectivity and discursive frame. The concept of primordialist universalism offers social scientists a tool for making sense of hybrid social phenomena that confound traditional categories of political analysis.     

Why theatre-based research works? Psychological theories from behind the curtain

While many scholars have demonstrated the effectiveness of theatre-based knowledge mobilization, fewer studies have examined its psychological dimensions. This article examines some psychological theories that may account for the success behind theatre-based knowledge mobilization. Drawing from the Canadian Experience Project, a study about the labor market challenges of skilled immigrant workers, we show how theatre-based research dissemination efforts attempt to achieve optimal stress by using aesthetic distance processes. We maintain that this psychological capacity to attune to audience members, especially evident in forum theatre, makes theatre a particularly effective means for knowledge mobilization.     

Dopamine D2 agonist affects visuospatial working memory distractor interference depending on individual differences in baseline working memory span

The interplay of dopaminergic striatal D1–D2 circuits is thought to support working memory (WM) by selectively filtering information that is to be remembered versus information to be ignored. To test this theory, we conducted an experiment in which healthy participants performed a visuospatial working memory (VSWM) task after ingesting the D2-receptor agonist cabergoline (or placebo), in a randomized, double-blinded, crossover design. Results showed greater interference from distractors under cabergoline, particularly for individuals with higher baseline dopamine (indicated by WM span). These findings support computational theories of striatal D1–D2 function during WM encoding and distractor-filtering, and provide new evidence for interactive cortico-striatal systems that support VSWM capacity and their dependence on WM span.     

Empathy,Einfühlung,and aesthetic experience: the effect of emotion contagion on appreciation of representational and abstract art using fEMG and SCR

Since the advent of the concept of empathy in the scientific literature, it has been hypothesized, although not necessarily empirically verified, that empathic processes are essential to aesthetic experiences of visual art. We tested how the ability to “feel into” (“Einfühlung”) emotional content—a central aspect of art empathy theories—affects the bodily responses to and the subjective judgments of representational and abstract paintings. The ability to feel into was measured by a standardized pre-survey on “emotional contagion”—the ability to pick up and mirror, or in short to “feel into”, emotions, which often overlaps with higher general or interpersonal empathetic abilities. Participants evaluated the artworks on several aesthetic dimensions (liking, valence, moving, and interest), while their bodily reactions indicative of empathetic engagement (facial electromyography—EMG, and skin conductance responses—SCR) were recorded. High compared to low emotion contagion participants showed both more congruent and more intense bodily reactions (EMG and SCR) and aesthetic evaluations (higher being moved, valence, and interest) and also liked the art more. This was largely the case for both representational and abstract art, although stronger with the representational category. Our findings provide tentative evidence for recent arguments by art theorists for a close “empathic” mirroring of emotional content. We discuss this interpretation, as well as a potential tie between emotion contagion and a general increase in emotion intensity, both of which may impact, in tandem, the experience and evaluation of art.
