Time course of chord priming

The time course of chord priming was explored in four experiments. In chord priming, a chord (a typical combination of simultaneously sounded tones) primes other chords that are musically related. In the present study, the prime duration and the stimulus onset asynchrony (SOA) between the prime chord and the chord to be judged were varied. Priming occurred at an SOA and prime duration as short as 50 msec, the shortest tested. When the prime duration was held constant at 50 msec, priming occurred at an SOA as long as 2,500 msec, the longest tested, and the magnitude of the priming effect did not diminish. To eliminate a possible role of sensory memory in maintaining the priming effect during the silence following the prime, a 250-msec noise mask was presented immediately following the 50-msec prime. The interpolated noise mask did not eliminate priming, thereby supporting the view that chord priming is the consequence of associative activation.

躯体性和心理性应激对大鼠血浆皮质酮变化的影响

本实验以血浆皮质酮分泌量为大鼠应激反应指标。实验分三阶段进行:Ⅰ期.适应(第1～7天),在此期所有动物对环境及实验盒适应性训练。Ⅱ期.心理性应激的形成(第8～14天).随机分三组进行:对照(C)组仅给不规则光;规则光(R)组给光后再于尾部施电刺激,光与电刺激间隔恒定;不规则光(Ⅰ)组给光和电刺激,但两者间隔随机。C、R、I三组所接受的光刺激量相等,R、I组所接受的电刺激量相等。Ⅲ期.心理性应激的记忆(第15天).此期各组电刺激均撤除,余同第Ⅱ期。结果显示,在Ⅱ期末及Ⅲ期,R、I组血浆皮质酮均明显高于C组,I组高于R组。     

Association between adolescent rough-and-tumble play and conduct problems,substance use,and risk-taking behaviors: Findings from a school-based sample

Rough-and-tumble play (RTP), also known as play fighting, is a common form of play frequently reported and studied by researchers. However, one important limitation of past research in the area of RTP has been the neglect of the adolescence period. Consequently, little is known about the function of adolescent RTP as well as about clinical characteristics of youth who engage in this activity after childhood. In a school-based sample of 1,771 middle school students (ages 9–16 years), the current study sought to address this gap by examining, via bivariate and multivariate logistic regression analyses, the potential cross-sectional associations of adolescent RTP with (a) selected demographic variables, (b) conduct problem symptoms, (c) substance use, and (d) risk-taking behaviors, including adjustment for several demographic confounders. Results indicated that adolescents reporting higher rates of conduct problem symptoms were more likely to report a recent participation in RTP. In addition, substance use (experimentation and current consumption of tobacco, alcohol, and marijuana) and risk behaviors assessed all were strongly associated with an increased likelihood of reporting an engagement in RTP. This finding suggests that participation in this activity probably implicates particular phenotypic characteristics including the propensity to engage in health-damaging behaviors. But the most profound issue raised by this research concerns the strong relationship between RTP and great levels of conduct disorder symptoms, suggesting a possible significant change in the functional significance of RTP in the adolescence period.     

“No,You're Playing the Race Card”: Testing the Effects of Anti-Black,Anti-Latino,and Anti-Immigrant Appeals in the Post-Obama Era

Despite a sizable literature on racial priming, scholars have failed to account for the shifting nature of racial appeals. First, theories of racial priming have not yet been widely applied to increasingly common anti-immigrant and anti-Latino political appeals. Second, theories of racial priming have not adequately accounted for both an increasingly racialized political climate and increased tolerance for explicit anti-minority appeals. In two survey experiments fielded both before Trump's rise and after his presidential victory, we find the Implicit-Explicit (IE) model always fails for anti-black appeals, sometimes fails for anti-immigrant appeals, but consistently holds for anti-Latino appeals. While we find the null effects of implicit versus explicit anti-black and anti-immigrant appeals are partly driven by tolerance for the explicit appeals, we also find evidence that white Americans are adept at recognizing the racial content of appeals featuring widely used, congruent issue-group pairs. Our findings shed light on conditions under which the IE model does and does not hold in the current political era.     

Leibnizian Identity and Paraconsistent Logic

The standard Leibnizian view of identity allows for substitutivity of identicals and validates transitivity of identity within classical semantics. However, in a series of works, Graham Priest argues that Leibnizian identity invalidates both principles when formalized in paraconsistent semantics. This paper aims to show the Leibnizian view of identity validates substitutivity of identicals and transitivity of identity whether the logic is classical or paraconsistent. After presenting Priest's semantics of identity, I show what a semantic expression of Leibnizian identity does amount to. Then, I argue that Priest's semantic definition of identity is not Leibnizian. Finally, I offer a semantics characterization of identity in paraconsistent logic that is truly Leibnizian. I demonstrate that the correct formalization of Leibnizian identity in paraconsistent logic also validates substitutivity of identicals and transitivity of identity.     

Consequences of Supervisor Knowledge Hiding in Organizations: A Multilevel Mediation Analysis

Drawing on the theoretical framework of social cognitive theory, our study explores the multilevel mediation model in which moral disengagement (level-1) mediates the direct relationships between knowledge hiding by supervisors from subordinates (KHSS: level-2) and supervisor directed organizational citizenship behavior (SOCB: level-1) and supervisor directed silence (SS: level-1). Drawing on multi-sourced, multi-timed, and multilevel data of 306 subordinates nested within 83 supervisors, multilevel structural equation modeling (ML-SEM) was used to test the proposed model. The results demonstrate that KHSS, first, fosters subordinates’ moral disengagement, which in turn reduces their SOCB and enhances their SS. Our findings offer several useful theoretical and managerial implications of the negative consequences of supervisor knowledge hiding in organizations. As one of the first studies to provide empirical evidence for the existence of supervisor knowledge hiding (i.e. KHSS), this research highlights the consequences of KHSS on subordinates’ moral disengagement, SOCB, and SS.

Influence of intracerebroventricular administration of dopaminergic drugs on morphine state-dependent memory in the step-down passive avoidance test

The effects of dopaminergic drugs on morphine state-dependent memory of passive avoidance task were examined in mice. Pre-training administration of morphine (5mg/kg) led to state-dependent learning with impaired memory retrieval on the test day which was reversed by pre-test administration of the same dose of the opiate. The pre-test intracerebroventricular (i.c.v.) administration of the dopamine D1 receptor agonist (SKF38393), dopamine D2 receptor agonist (quinpirole) and dopamine D2 receptor antagonist (sulpiride) not only reversed the effect of pre-training morphine treatment, but also increased this action of the drug. Furthermore, the pre-test i.c.v. administration of dopamine D1 receptor antagonist (SCH23390) prevented the restoration of memory by morphine. In conclusion, the morphine-induced recovery of memory, on the test day, seems to be induced, at least in part, through dopamine receptors.
