Young children's storage behavior in a memory-for-location task

Two experiments concerned with children's intentional preparation for future retrieval in a memory-for-location task are presented. In the first experiment, 3-, 5-, 7-, and 9-year-olds were instructed to store and subsequently retrieve an object on a large spatial display. All age groups, except the 3-year-olds, tended to store the object at distinctive locations and their retrieval performance was facilitated accordingly. The four age groups did not differ in the types of selections made in a nonmemory control task. The second experiment dealt with the effects of feedback and informational factors on strategy acquisition. Preschoolers were given experience at retrieving the object from distinctive and nondistinctive positions on the stimulus display. Later, when instructed to store the object by themselves, older preschoolers produced the distinctive-position storage strategy following a feedback procedure in which they directly observed the consequences of their retrieval selections. The strategy was adopted by younger preschoolers, but only when additional strategy and task information accompanied visual feedback. The use of external memory tasks with young children and factors affecting strategy acquisition and utilization are discussed.     

Remembrance of places lasts: Proactive inhibition and patterns of choice in rat spatial memory

A series of experiments was carried out to evaluate the notion that rats given a sequence of massed daily trials on the radial maze reset working memory at the end of each trial by deleting its contents. Although curves presented by D. S. Olton [Scientific American, 1977, 236, 82–98; In S. H. Hulse, H. Fowler, & W. K. Honig (Eds.), Cognitive processes in animal behavior, Hillsdale, N.J.: Erlbaum, 1978] show that rats return to errorless performance at the beginning of each trial after the first, the fact that accuracy falls less rapidly over choices on Trial 1 than on subsequent trials suggests a proactive inhibition (PI) effect. In Experiment 1, Olton's findings were replicated, and a PI effect was observed on Days 1–2 of testing. On Days 3–5, overall accuracy improved significantly and was associated with the development of a strong tendency for rats to enter adjacent alleys, which became particularly marked on the final trials of a day's testing. In order to prevent rats from achieving accurate performance by using an adjacent alleys pattern, a procedure was used in Experiment 2 which involved initial forced random choices followed by a retention test consisting of free choices. Repeated daily trials with this procedure yielded a significant PI effect, which was more marked at a 60-sec delay than at a 0-sec delay. Experiments 3 and 4 showed this PI effect to be robust and resistant to manipulations designed to produce release from PI. Both the PI effect and a strong tendency found in Experiment 1 for animals to avoid on the initial choices of Trial n those alleys most recently entered on Trial n?1 argue that rats do not reset working memory between trials.     

The effects of intrinsic and extrinsic rewards in a risk-taking situation

This study varied both the intrinsic and extrinsic rewards associated with performing a task in a risk taking situation. When the task performed to win a prize provided little if any intrinsic reward, subjects liked and tried for prizes that were easy to obtain. In contrast, when the task was intrinsically rewarding, subjects liked and tried for those prizes that were somewhat more difficult to obtain. In addition, subjects were more likely to like and try for prizes easier to obtain when the extrinsic reward was high.     

The Adaptive Logic of Compatibility

This paper describes the adaptive logic of compatibility and its dynamic proof theory. The results derive from insights in inconsistency-adaptive logic, but are themselves very simple and philosophically unobjectionable. In the absence of a positive test, dynamic proof theories lead, in the long run, to correct results and, in the short run, sometimes to final decisions but always to sensible estimates. The paper contains a new and natural kind of semantics for S5from which it follows that a specific subset of the standard worlds-models is characteristic for S5.     

A multi-method investigation of the personality correlates of digital aggression

Digital aggression (DA) refers to the use of computer-mediated technologies to harm others. A handful of previous studies have provided mixed results regarding the personality correlates of DA. We clarified these findings by analyzing the associations between three measures of DA (behavioral, Twitter, and self-report) and the Big Five traits using data from 1167 undergraduate participants. Big Five personality trait measures predicted all three DA measures, but results varied across particular assessments of DA. These results point to possible moderators and potentially important differences within the broader construct of DA.     

瞳孔变化在记忆加工中的生物标记作用

瞳孔在不同记忆任务的同一加工阶段内具有变化模式的一致性, 瞳孔的缩放变化反映了信息加工过程中神经系统的激活状态。在刺激呈现前的预编码阶段, 瞳孔随个体注意集中水平的提高而收缩。在信息编码阶段, 瞳孔扩张程度作为相继记忆效应的生物标记, 可预测信息未来提取阶段的回忆成绩。在信息提取阶段, 采用自由回忆任务时, 瞳孔随记忆负荷的释放而迅速收缩, 但每个项目的提取均会引发小幅度瞳孔扩张; 而在再认提取任务中, 呈现旧刺激比呈现新刺激时瞳孔扩张更明显, 产生瞳孔新旧效应。瞳孔是记忆加工中敏感而稳定的生物标记, 而瞳孔测量法是探究记忆加工生理机制的有效手段。未来可以从瞳孔追踪术的角度, 采用多种研究手段进一步探究记忆的生理机制。     

The construct of the ‘mana personality’ in Jung’s works: a historic-hermeneutic perspective. Part I

According to Jung, the ‘mana personality’ represents an archetypal phase of the individuation process of remarkable interest in psychological, hermeneutic and theoretical terms. This figure is characterized by a high initiatic potential that fosters the approximation of the consciousness of the Self. At the same time, it entails a risk of psychic inflation or of ‘similarity to God’. In this article, divided in two parts, I deal with those aspects through a reconstruction of the development of this notion within Jung’s published works, adopting a primarily chronological and, secondarily, thematic approach moving from a textual analysis of relevant passages. In this first part, I consider some passages which deal mainly with the risks of the assimilation of the unconscious in ‘La structure de l’inconscient’ (1916) that preceded the successive proper treatment of the mana personality’s notion presented, and here examined, in ‘The relations between the ego and the unconscious’ (1928). Successively, I take into consideration some further issues related to it discussed by Jung in ‘The structure of the psyche’ (1928/1931), ‘Archaic man’ (1931), and ‘Nietzsche’s Zarathustra’.     

The construct of the ‘mana personality’ in Jung’s works: a historic-hermeneutic perspective. Part II

This is the second part of an article that tries to provide a framework of understanding of, and a seminal reflection on, a highly interesting yet little explored psychological construct of Jung’s analytical psychology, namely the ‘mana personality’. Here I take into consideration some issues around the ‘saviour complex’, discussed in Jung’s seminar on Nietzsche’s Zarathustra, concerning both the psychological analysis of the individual and the socio-political level related to the collective horizon of the 1930s. Moreover, I consider the continuity of Jung’s analysis of such issues in other works such as ‘Psychology and national problems’ (1936), Symbols of Transformation (1952), and Aion (1950). I finally make some suggestions concerning Jung’s apparent hermeneutic tendency to apply the construct of the mana personality to collective historical phenomena.
