The view that successful memory performance depends importantly on the extent to which there is a match between the encoding
and retrieval conditions is commonplace in memory research. However, Nairne (Memory, 10, 389–395, 2002) proposed that this idea about trace–cue compatibility being the driving force behind memory retention is a myth, because
one cannot make unequivocal predictions about performance by appealing to the encoding–retrieval match. What matters instead
is the relative diagnostic value of the match, and not the absolute match. Three experiments were carried out in which participants
memorised word pairs and tried to recall target words when given retrieval cues. The diagnostic value of the cue was varied
by manipulating the extent to which the cues subsumed other memorised words and the level of the encoding–retrieval match.
The results supported Nairne’s (Memory, 10, 389–395, 2002) assertion that the diagnostic value of retrieval cues is a better predictor of memory performance than the absolute encoding–retrieval
match. 相似文献

Past research has shown a close relationship between self-esteem (SE) and life satisfaction (LS). Using cross-lagged structural equation modeling, the current longitudinal study examined the directionality of the relationship among a sample of Chinese university students (214 males and 134 females). In the model, SE and LS at Time 1 were used to predict SE and LS at Time 2, with socioeconomic status (SES) as the independent variable of both constructs. Results showed that SE consistently predicted subsequent LS among both genders, whereas no significant effects of LS on subsequent SE were found. Furthermore, SES had significant effects on LS among both genders. Its influence on SE, however, was significant among females only. Implications and limitations are discussed. 相似文献

In this study, we used event-related potentials (ERPs) to evaluate the contribution of surface color and color knowledge information in object identification. We constructed two color-object verification tasks - a surface and a knowledge verification task - using high color diagnostic objects; both typical and atypical color versions of the same object were presented. Continuous electroencephalogram was recorded from 26 subjects. A cluster randomization procedure was used to explore the differences between typical and atypical color objects in each task. In the color knowledge task, we found two significant clusters that were consistent with the N350 and late positive complex (LPC) effects. Atypical color objects elicited more negative ERPs compared to typical color objects. The color effect found in the N350 time window suggests that surface color is an important cue that facilitates the selection of a stored object representation from long-term memory. Moreover, the observed LPC effect suggests that surface color activates associated semantic knowledge about the object, including color knowledge representations. We did not find any significant differences between typical and atypical color objects in the surface color verification task, which indicates that there is little contribution of color knowledge to resolve the surface color verification. Our main results suggest that surface color is an important visual cue that triggers color knowledge, thereby facilitating object identification. 相似文献

This paper focuses on the hidden costs of expressing anger in negotiations. Two experimental studies show that an opponent’s expression of anger can elicit both concessionary and retaliatory responses by focal negotiators. In the first study, equal-power negotiators exhibited overt concessionary behaviors when their opponents expressed anger, but also sabotaged their opponents covertly. Feelings of mistreatment mediated the relationship between opponents’ anger expression and focal negotiators’ covert retaliation. In the second study, low-power negotiators made larger concessions when high-power opponents expressed anger, but they retaliated covertly against high-power negotiators. High-power negotiators were overtly demanding (and not concessionary) regardless of whether or not the opponent expressed anger, but also retaliated covertly against low-power opponents who expressed anger. The two studies suggest that the value-claiming advantages of expressed anger need to be weighed against the costs of eliciting (covert) retaliation. We discuss implications of the findings and provide recommendations for future research. 相似文献

该研究采用不同加工任务的间接测量方法,探讨不同心理一致感水平初中生对压力的外显认知倾向和内隐态度激活程度。结果表明:1)初中生较为稳定的积极认识和反应倾向在他们关于压力的外显认知加工中起了更为显著的作用;2)不同加工方式的虚惊率差异表明存在着初中生对压力情境的内隐态度,且这种无意识认知较为消极。 相似文献

Although women report feeling more pain than men, their pain is often underdiagnosed and undertreated. By proposing a gender-based theoretical conceptualisation, we argue that such sex-related biases may be enhanced or suppressed by contextual variables pertaining to the clinical situation, the perceiver or the patient. Consequently, we aimed to explore the moderator role of two clinically relevant variables in a chronic low-back pain (CLBP) scenario: diagnostic evidence of pathology (EP) and pain behaviours conveying distress. One-hundred and twenty-six female nurses (M?=?35.33, SD?=?7.64) participated in an experimental between-subjects design, 2 (patient's sex)?×?2 (EP: present vs. absent)?×?2 (pain behaviours: with vs. without distress). Independent variables were operationalised by vignettes depicting a patient with CLBP. Nurses judged the patient's pain on several dimensions: (1) credibility; (2) disability; (3) severity of the clinical situation; (4) psychological attributions and (5) willingness to offer support. Main findings showed that judgements of women's pain were influenced by EP, while judgements of men's pain were not. Moreover, nurses showed biases against men, but only in the presence of EP. The influence of distress cues was less consistent. Theoretical and practical implications are drawn. 相似文献

Introduction and Aim: Neurological subtle signs (NSS) are often observed during the neurological examination of children and tend to disappear with age. Their persistence into late adolescence or young adulthood has been related to psychiatric and neurocognitive disorders. To provide a better understanding of their functional basis, a longitudinal correlational study with neurocognitive measurements was performed. Method: We conducted multiple regression and correlation analyses of NSS with demographic and cognitive measures on a subset of 341 healthy children (56% males), taking part in a longitudinal dental study. Participants, whose ages ranged between 11–15 years, at first evaluation, undertook yearly, during 5 years, a 6-item NSS exam (producing a total score ranging between 0–18) and a comprehensive battery of neurocognitive tests. Effects of age, gender, IQ, and 7 neurocognitive factors on NSS were analyzed. Results: Over the years, NSS scores correlated consistently with selective attention (Stroop test), motor speed (finger tapping), and visuomotor speed (pegboard speed). Discussion: These results suggest that the disappearance of NSS in late childhood and adolescence occurs primarily in parallel with the development of motor and visuomotor functions and secondarily in relation to higher order functions such as selective attention (Stroop) and executive control (B-A Trails difference). 相似文献

We report an abnormally high residual dislocation density in aluminium in an Al/Ti/Al laminate annealed at 873 K for seven days. The residual dislocation density reaches 7.5 × 1014 m?2, higher than that in aluminum after severe plastic deformation processes such as accumulative roll bonding and high-pressure torsion. It is proposed that the high residual dislocation density may result from obstruction of the movement of TiAl3 nanoparticles by the grain boundary and Ti atoms conglomerating at vacancies distributed in the aluminium matrix at a high temperature for a sufficient time to allow a relatively stable crystal. 相似文献
