A new experimental method to identify the process of logical reasoning

Abstract: A new method to identify the process of logical reasoning is presented. In spite of its indispensability and importance, we have had few methods to identify a subject's reasoning process, except that of using verbal protocol data. In this paper, for the purpose of objective identification of the reasoning process, we propose a new method to obtain the subject's reasoning process, in terms of a resolution tree for a task of which the logical structure can be written by first-order predicate logic. The results of an experiment using this method are presented. They revealed some interesting features of human reasoning such as, large differences between subjects, remarkable parallel processes, and the existence of subgoals for each subject.

消极情绪在程序和互动不公正感与员工偏离行为间的中介作用:传统性的调节机制

采用问卷调查法对341名员工及其同事进行调查,从情绪和文化传统性视角,探讨了程序和互动不公正对员工偏离行为的影响及其内在作用机制.结果表明:(1)消极情绪是组织不公正感对员工偏离行为作用的中介变量;(2)传统性对组织不公正感对员工偏离行为的影响作用具有调节效果;(3)使用总效应调节模型对消极情绪在组织不公正感对员工偏离行为的中介效应及传统性的调节作用进行综合性分析,发现传统性主要在第二阶段,即消极情绪对员工偏离行为的影响作用上调节效果显著.     

Giving everything for athletic success! – Sports-specific risk acceptance of elite adolescent athletes

ObjectivesGood health is the basic foundation for peak performance in elite sports, yet athletes are often conflicted between protecting their health for the sake of being able to compete and risking their health in the form of potential injuries to achieve even higher levels of performance. Adolescent athletes, who are in a sensitive phase of development, are especially prone to negative consequences like injuries or illnesses due to risky behaviors. In an effort to prevent lasting damage, the present study aims to identify groups of athletes who are particularly willing to take risks and the possible determinants of athletes' risk acceptance.Design and methodIn our German Young Olympic Athletes' Lifestyle and Health Management (GOAL) Study, we examined 1138 German national squad members, aged 14–18, representing all Olympic sports. Classification tree analyses enabled us to detect determinants of high and low risk groups concerning sports-specific psychosocial and physical risk acceptance.ResultsWe found several high risk groups. In general, the degree of inclusion in the elite sports system correlates positively with risk acceptance. Athletes who are extremely willing to take physical risks attached high importance to their sports environment and minor importance to their non-sports environment (n = 94; 8%). Athletes who are perfectionists and very focused on their performance were particularly willing to accept physical (n = 142; 13%) and social risks (n = 75; 7%).ConclusionBy identifying extreme groups with an especially high or low willingness to take risks and the determinants of these groups, we can give a more precise picture of elite adolescent athletes' risk acceptance.     

Walking through doorways causes forgetting: Further explorations

Previous research using virtual environments has revealed a location-updating effect in which there is a decline in memory when people move from one location to another. Here we assess whether this effect reflects the influence of the experienced context, in terms of the degree of immersion of a person in an environment, as suggested by some work in spatial cognition, or by a shift in context. In Experiment 1, the degree of immersion was reduced by using smaller displays. In comparison, in Experiment 2 an actual, rather than a virtual, environment was used, to maximize immersion. Location-updating effects were observed under both of these conditions. In Experiment 3, the original encoding context was reinstated by having a person return to the original room in which objects were first encoded. However, inconsistent with an encoding specificity account, memory did not improve by reinstating this context. Finally, we did a further analysis of the results of this and previous experiments to assess the differential influence of foregrounding and retrieval interference. Overall, these data are interpreted in terms of the event horizon model of event cognition and memory.     

Visual memory for feature bindings: The disruptive effect of responding to new perceptual input

In the current study, we examined how short-term memory for location–identity feature bindings is influenced by subsequent cognitive and perceptual processing demands. Previous work has shown that memory performance for feature bindings can be disrupted by the presentation of subsequent visual information, particularly when this information is similar to that held in memory. The present study demonstrates that memory performance for feature bindings can be profoundly disrupted by also requiring a response to visual information presented subsequent to the visual memory array. Across five experiments, memory for a location–identity binding was substantially impaired following a localization response to a following item that matched the location but mismatched the identity of the memory target. The results point to an important role for action in the episodic integration processes that control short-term visual memory performance.     

The reminiscence bump in older adults' life story transitions

Older adults' memories of events that occurred in adolescence and early adulthood are over-represented compared to other lifetime periods. Prior research on this reminiscence bump has focused on qualities of individual memories. The present study used a novel interview method to examine the potential role played by mental representations of extended lifetime periods. Older adults provided oral life stories, and they divided their transcribed narratives into “chapters”. Participants' ages at chapter beginnings and endings showed pronounced reminiscence bumps. The results are consistent with the idea that personal episodes occurring near the boundaries of extended lifetime periods receive preferential processing that enhances long-term memory.     

The neural basis of updating: Distinguishing substitution processes from other concurrent processes

Sörqvist, P. & Sætrevik, B. (2010). The neural basis of updating: Distinguishing substitution processes from other concurrent processes. Scandinavian Journal of Psychology, 51, 357–362. Most previous studies of updating processes have not been able to contrast processes of substituting items in memory with other concurrent processes. In the present investigation, we used a new task called “number updating” and an fMRI protocol to contrast the activation of trials that require item substitution (adding a new item to the working memory representation and suppressing an old item) with trials that involve no substitution (discarding the new item). Trials that require item substitution activated the dorsolateral prefrontal cortex, the posterior medial frontal cortex and the parietal lobes, areas typically seen activated for working memory tasks in general. Trials that do not require substitution activated the anterior medial frontal cortex. Studies examining executive functions have associated this area with cognitive conflict, and may represent suppression of the substitution processes.     

Do we map remembrances to the left/back and expectations to the right/front of a mental timeline? Space–time congruency effects with retrospective and prospective verbs

Recent experimental studies have shown that people code time in terms of a mental timeline which typically runs from left to right or from back to front. Determining the cognitive function of this mental timeline for language processing, however, is still an unsettled issue. Whereas the studies of Ulrich and Maienborn (2010) and Ulrich et al. (2012) argue against an automatic activation of the mental timeline for the interpretation of tense and temporal adverbials at sentence level, Sell and Kaschak (2011) observe an automatic activation for the processing of past- and future-related sentences in small stories. The present paper reports the results of three experiments which examine the processing of sentences with retrospective and prospective verbs (e.g., to remember, to regret vs. to expect, to announce) in present tense, which locate a second, embedded event in the past or the future. When temporal information was task-relevant, a space–time congruency effect emerged (Experiment 1). This suggests that the mental timeline is not only linked to overtly deictic linguistic material but may also be construed in a more intricate way through the compositional construction of sentence meaning. The congruency effect disappeared, however, when temporal information was task-irrelevant (Experiments 2 and 3), suggesting that the mental timeline is not functionally involved in the cognitive processing of these especially demanding two-event sentences. The results of the present study support the conclusion that the relevant factor driving an automatic activation of the mental timeline is not the number of linguistically expressed events, but might rather be the number of sentential units.
