Within-session spacing improves delayed recall in children

Multiple retrievals of a memory over a spaced manner improve long-term memory performance in infants, children, younger and older adults; however, few studies have examined spacing effects with young school-age children. To expand the understanding of the spacing benefit in children, the current study presented weakly associated English word-pairs to children aged 7–11 and cued their recall two times immediately (massed), after a delay of 5 or 10 items (spaced) or not at all (control). After this encoding session with or without two retrievals, participants were tested two times for memory of all word-pairs: immediately and 30 minutes after the encoding session. Multiple retrievals significantly improved memory on the tests. However, words repeated in a spaced design were remembered at higher rates than those that were massed, while gap size between repetitions (5 or 10) did not differentially impact performance. The data show that a within-session spacing strategy can benefit children's ability to remember word-pairs after 30 minutes. Thus, asking students to recall what they have learned within a lesson is a technique that can be used in a classroom to improve long-term recall.

The grandfather

The author, grandson of C.G. Jung, architect and historian, resident in the Küsnacht house, offers perspectives on the role of the grandfather. C.G. had a difficult relationship with his father but felt a strong rapport with his grandfather Karl Gustav Jung, even though he died before C.G.'s birth. Andreas notes that there were many parallels in the lives of the two men; C.G.'s memories and the touching personal diary left behind by Karl Gustav will be discussed. Many of Jung's other ancestors will be described from his own personal angle. The paper also encompasses C.G.'s spiritual forerunners and finally the dead, our common nameless ancestors.     

应激干预对不同行为类型大学生心率血压手指温度的影响

探讨应激干预对心率、血压、手指温度的影响及不同行为类型的差异。被试为河北师范大学本科生72人(A、B型各36人),应激干预为音乐放松、腹式呼吸和静坐休息,实验包括基线期-干预期-应激期-恢复期四个阶段,在观看紧张性影片前进行应激前干预,记录被试的心率、血压、手指温度。结果发现,就缓解应激所产生的交感神经活动增强来说,音乐放松效果较好,腹式呼吸也明显优于自然休息;行为类型（A、B）和应激干预大多表现出来交互作用;个体生理反应的性别差异与生理指标有关,基线值的性别差异较大时,男女生的生理数据不宜混合在一起,基线值相差不大时,可以用相对值（如变化值或变化率）进行统计处理。说明行为类型（A、B）对于应激而言是一种微调变量,在自然休息状态或者低应激水平下作用更明显,应激水平较高时,行为类型的调节作用会显著降低;不同应激干预适用不同行为类型个体     

Identical Twins,Deduction Theorems,and Pattern Functions: Exploring the Implicative BCSK Fragment of S5

We recapitulate (Section 1) some basic details of the system of implicative BCSK logic, which has two primitive binary implicational connectives, and which can be viewed as a certain fragment of the modal logic S5. From this modal perspective we review (Section 2) some results according to which the pure sublogic in either of these connectives (i.e., each considered without the other) is an exact replica of the material implication fragment of classical propositional logic. In Sections 3 and 5 we show that for the pure logic of one of these implicational connectives two – in general distinct – consequence relations (global and local) definable in the Kripke semantics for modal logic turn out to coincide, though this is not so for the pure logic of the other connective, and that there is an intimate relation between formulas constructed by means of the former connective and the local consequence relation. (Corollary 5.8. This, as we show in an Appendix, is connected to the fact that the ‘propositional operations’ associated with both of our implicational connectives are close to being what R. Quackenbush has called pattern functions.) Between these discussions Section 4 examines some of the replacement-of-equivalents properties of the two connectives, relative to these consequence relations, and Section 6 closes with some observations about the metaphor of identical twins as applied to such pairs of connectives.     

Personal values and immigrant group appraisal as predictors of voluntary contact with immigrants among majority students in Israel

What predicts whether young people will establish contacts with immigrants? Students are at a pivotal point in which the campus environment can enable substantial contact with immigrants, and where world views and behavioural patterns are formed which can follow through their adult lives. Through a value‐attitude‐behavior paradigm we examine a conceptual model in which appraisal of an immigrant group as a threat and/or benefit to the host society mediates the relationship between personal values and contact. Findings among 252 students in Israel showed that (1) threat/benefit appraisal of immigrants predicted voluntary contact; (2) personal values of self‐direction and hedonism directly predicted voluntary contact; and (3) Threat/benefit appraisal mediated the relationship between self‐direction and power and contact. Results suggest that increasing awareness of benefits of immigrants can promote positive inter‐group relations.     

Examining the Effects of Exercise on Pattern Separation and the Moderating Effects of Mood Symptoms

Aerobic exercise has broad cognitive benefits. One target of interest is enhanced memory. The present study explored pattern separation as a specific memory process that could be sensitive to acute and regular exercise and clinically significant for disorders (e.g., depression) characterized by cognitive-affective deficits and hippocampal impairment. In a within-subjects design, participants (N = 69) attended two visits during which they repeated a behavioral pattern separation task at rest and after an activity (cycling, stretching). Regular exercise habits, demographics, mood and anxiety symptoms, and recognition memory capacity were also measured. More regular exercise predicted better resting pattern separation, t(62) = 2.13, b = 1.74, p = .037. Age moderated this effect, t(61) = 2.35, b = .25, p = .02; exercise most strongly predicted performance among middle-age participants. There was no main effect of activity condition on post-activity performance, t(61) = .67, p = .51. However, with significant heterogeneity in reported mood symptoms and regular exercise habits, there was a three-way interaction between condition, regular exercise, and depression, t(55) = 2.08, b = .22, p = .04. Relative to stretching, cycling appears to have enhanced the benefit of regular exercise for pattern separation performance; however, this was evident among participants with mild to no symptoms of depression, but absent among participants with moderate to severe symptoms. Results have implications for how exercise might protect against declines in pattern separation. Future research should explore exercise’s potential as a prevention tool or early intervention for pattern separation and related clinical outcomes.     

Anxious attachment as an antecedent of people's aversion towards pattern deviancy

Research suggests that people's aversion towards pattern deviancy—distortions of repeated forms or models—contributes to social phenomena, such as prejudice. Yet, the factors motivating pattern deviancy aversion remain unclear. Potentially, anxious attachment, as it entails hypervigilant detection of and reactivity to social inconsistency and unreliability, heightens pattern deviancy aversion. In Studies 1 (N = 137) and 2 (N = 102), anxious but not avoidant attachment predicted aversion towards broken patterns of geometric shapes. In Studies 3 (N = 310) and 4 (N = 470), experimentally inducing anxious versus avoidant and secure attachment (Study 3), and versus a neutral prime (Study 4), heightened pattern deviancy aversion. Controlling for participants’ aversion towards unbroken patterns, novel objects, and negative stimuli did not change these results. Our findings demonstrate that anxious attachment is one antecedent of pattern deviancy aversion, and suggest that pattern deviancy aversion may underlie links between anxious attachment and certain social phenomena.
