At the beginning of the 20th century, Alfred Binet sought teaching positions at the Collége de France and the Sorbonne. Binet wanted to develop experimental psychology in France, but the strong psychopathological orientation of French psychology blocked his ambition. The 1st part of this article relates the history of the introduction of psychology, via Théodule Ribot, to the Sorbonne and the Collège de France. Ribot's premature retirement from the Collège de France in 1901 triggered a battle that led to Binet's repeated failure to gain access to these institutions of highter education and the success in 1902 of Ribot's students: Pierre Janet at the Collège de France and George Dumas at the Sorbonne. 相似文献

Post-training cyclooxygenase-2 (COX-2) inhibition impairs memory consolidation 总被引:9,自引:1,他引:8 下载免费PDF全文
Evidence indicates that prostanoids, such as prostaglandins, play a regulatory role in several forms of neural plasticity, including long-term potentiation, a cellular model for certain forms of learning and memory. In these experiments, the significance of the COX isoforms cyclooxygenase-1 (COX-1) and cyclooxygenase-2 (COX-2) in post-training memory processes was assessed. Adult male Long-Evans rats underwent an eight-trial (30-sec intertrial interval) training session on a hippocampus-dependent (hidden platform) or dorsal striatal–dependent (visible platform) tasks in a water maze. After the completion of training, rats received an intraperitoneal injection of the nonselective COX inhibitor indomethacin, the COX-1–specific inhibitor piroxicam, the COX-2–specific inhibitor N-[2-cyclohexyloxy-4-nitrophenyl]-methanesulfonamide (NS-398), vehicle (45% 2-hydroxypropyl-β-cyclodextrin in distilled water), or saline. On a two-trial retention test session 24 h later, latency to mount the escape platform was used as a measure of memory. In the hidden platform task, the retention test escape latencies of rats administered indomethacin (5 and 10 mg/kg) or NS-398 (2 and 5 mg/kg) were significantly higher than those of vehicle-treated rats, indicating an impairment in retention. Injections of indomethacin or NS-398 that were delayed 2 h post-training had no effect on retention. Post-training indomethacin or NS-398 had no influence on retention of the visible platform version of the water maze at any of the doses administered. Furthermore, selective inhibition of COX-1 via post-training piroxicam administration had no effect on retention of either task. These findings indicate that COX-2 is a required biochemical component mediating the consolidation of hippocampal-dependent memory. 相似文献

Recent work has shown that correcting a dispositional inference may lead social observers to over‐emphasize the role of dispositional factors in subsequent judgments. This effect has been explained as a procedural rebound following a phase of dispositional suppression. We conducted two experiments to test an alternative explanation in terms of ego‐depletion. In Experiment 1, we compared the effects of ego‐depletion and dispositional rebound by relying on the attitude attribution paradigm and the cookie paradigm. In Experiment 2, we turned to a difficult math task in order to induce fatigue. We were able to replicate the dispositional rebound and the ego‐depletion effects but none of the experiments supported an ego‐depletion explanation of post‐suppression dispositional rebound.

The author investigated how elderly women who recently moved to senior centers reacted in comparison to same-age persons who were either better off or worse off than were the former. The author expected 2 individual difference variables related to uncertainty about oneself-sense of control and social comparison orientation-to interact with social comparison direction to produce affect. Contrary to this expectation, the author observed only main effects of social comparison direction on affect. The results indicated that downward comparison produced more negative affect (and less positive affect) than did upward comparison, independently of participants' individual differences. The results provide some useful information on the social psychology of aging. 相似文献

The authors investigated the effect of touch on a person's evaluation of the toucher in a field setting. In the context of selling a 2nd-hand car, the authors instructed a male seller to slightly touch (or not touch) a man who was interested in the car. After the participant left the seller, a female confederate solicited him, asking him to evaluate the car seller on various dimensions. The results showed that for each dimension that the participants evaluated, the touch condition was associated with statistically higher positive evaluations of the toucher than the no-touch control condition. 相似文献

The purpose of this study was to investigate how attentional focus on body sway affects postural control during quiet standing.
To address this issue, sixteen young healthy adults were asked to stand upright as immobile as possible on a force platform
in both Control and Attention conditions. In the latter condition, participants were instructed to deliberately focus their attention on their body sways
and to increase their active intervention into postural control. The critical analysis was focused on elementary motions computed
from the centre of pressure (CoP) trajectories: (1) the vertical projection of the centre of gravity (CoGv) and (2) the difference between CoP and CoGv (CoP–CoGv). The former is recognised as an index of performance in this postural task, whilst the latter constitutes a fair expression
of the ankle joint stiffness and is linked to the level of neuromuscular activity of the lower limb muscles required for controlling
posture. A frequency-domain analysis showed increased amplitudes and frequencies of CoP–CoGv motions in the Attention relative to the Control condition, whereas non-significant changes were observed for the CoGv motions. Altogether, the present findings suggest that attentional focus on body sway, induced by the instructions, promoted
the use of less automatic control process and hampered the efficiency for controlling posture during quiet standing. 相似文献

Recent models of the conceptual system hold that concepts are grounded in simulations of actual experiences with instances of those concepts in sensory-motor systems (e.g., Barsalou, 1999, 2003; Solomon & Barsalou, 2001). Studies supportive of such a viewhave shown that verifying a property of a concept in one modality, and then switching to verify a property of a different concept in a different modality generates temporal processing costs similar to the cost of switching modalities in perception. In addition to non-emotional concepts, the present experiment investigated switching costs in verifying properties of positive and negative (emotional) concepts. Properties of emotional concepts were taken from vision, audition, and the affective system. Parallel to switching costs in neutral concepts, the study showed that for positive and negative concepts, verifying properties from different modalities produced processing costs such that reaction times were longer and error rates were higher. Importantly, this effect was observed when switching from the affective system to sensory modalities, and vice-versa. These results support the embodied cognition view of emotion in humans. 相似文献

The purpose of the present research was to test the relevance of a theoretical framework based on the matches and the mismatches between desire for control and perception of control (Evans et al. in Br J Psychol 84(2):255–273, 1993), in order to predict autonomous motivation (Deci and Ryan in Intrinsic motivation and self-determination in human behavior. Plenum, New York, 1985, 2012), depression, and anxiety (Bradley in Handbook of psychology and diabetes: A guide to psychological measurement in diabetes research and practice. Harwood Academic Press, Chur, 1994; Bruchon-Schweitzer in Psychologie de la Santé: Modèles, concepts et méthodes. Dunod, Paris, 2002). Two prospective studies were run among undergraduate students. Results of Study 1 confirmed the relevance of Evans et al.’s (in Br J Psychol 84(2):255–273, 1993) theoretical framework. More specifically, four clusters reflecting different levels of desire for control and perception of control were found. Moreover, results revealed that profiles characterized by high scores on both desire for control and perception of control were more autonomously motivated than those characterized by the three other possible combinations. Results of Study 2 replicated those of Study 1 and showed that participants combining a low desire for control and a high perception of control were the less depressed, followed by participants with high scores on both measures. No significant effects were found for anxiety. 相似文献
