实验采用两种编码方式和测验类型考查了编码与提取方式的一致性对生成效应的影响。结果显示:(1)在进行字形加工的知觉辨认测验中,生成过程主要依据字形编码的形近字出现了生成效应;主要依据字义编码的反义字没有出现此效应。(2)在依赖字义提取的自由回忆中,形近字和反义字都出现了生成效应。因而编码与提取方式的一致性可能对生成效应有影响。 相似文献

Searle claims that for a machine to have intentional states it is not sufficient that a formal programme be instantiated. Various types of objections to this claim have been brought up by Searle's critics. Searle's replies to some of these objections are analysed. It turns out that it is more to these objections than Searle wants to make us believe. What is crucial, however, is that Searle's Gedankenexperiment results in a dilemma. At the outset of the dilemma there are two ways of not understanding. According to one of these ways a person (Searle's homunculus) does not understand something without knowing that s/he does not understand. While in the other mode the person knows that s/he doesn't understand. In the first case the inference from facts about the homunculus to facts about the computer is not valid whereas in the second case one would attribute mental states to the computer. Thereby Searle's claim turns out to be unfounded. 相似文献

Studies examining negative priming in dissociative identity disorder (DID) using the flanker task have reported emotional context effects. Significant negative priming is evident when individuals with DID are assessed in a context deemed emotionally neutral, while in contexts designed to elevate anxiety, DID samples display reduced negative priming. Limitations and considerations are discussed around statistical power, generalizability and reliability, and the use of diagnostic groups over specific clinical symptoms. The negative priming findings in this growing body of work have been interpreted with reference to the functioning of cognitive inhibitory mechanisms. Explored is how the episodic retrieval account of negative priming, with its reliance on memory mechanisms, could account for the DID findings. Encoding and retrieval possibilities are discussed and it is concluded that a failure to encode the prime trial distractor stimulus, in contexts of heightened anxiety, could explain the experimental findings from an episodic retrieval perspective. 相似文献

前人在项目回忆条件的合作记忆研究中记录到明显的合作抑制和错误修剪,背景提取条件的相关研究尤显不足;同时,情绪效价和编码水平对两类现象调节的研究尚未涉及。为此,本文在两个实验中采用经典合作记忆研究范式,以不同情绪效价的词汇为实验材料并以词汇在学习阶段的呈现颜色为背景展开研究。实验1和实验2分别在学习阶段采用了深编码和浅编码任务,回忆阶段则均含项目回忆(回忆已学词汇)和背景提取(回忆词汇在学习阶段的呈现颜色)两种任务。采用深编码条件的实验1的结果显示,项目回忆比背景提取条件的合作抑制更强、错误修剪更弱,回忆任务与词汇情绪效价交互影响合作抑制强度;采用浅编码条件的实验2则发现错误修剪在两种任务间的差异不显著。两实验的联合分析显示,回忆任务与编码水平交互影响合作抑制和错误修剪强度。上述结果表明:回忆任务对合作抑制和错误修剪的调节支持双重加工模型;回忆任务与情绪效价对合作抑制强度的交互影响支持权衡说,且与双重加工模型相吻合;回忆任务与编码水平交互影响合作抑制和错误修剪强度。 相似文献

Three experiments examined the assertion that presession handling cues that accompany training with reinforcement might account for spontaneous recovery when they reoccur following extinction. In Experiment 1, after extensive training on a variable-interval schedule, key pecking in pigeons was extinguished following either normal or distinctively different handling and transportational cues. Those cues resulted in enhanced spontaneous recovery 24 hr later when normal cues were reinstated. In Experiment 2, however, subjects tested following the normal handling cues showed no more spontaneous recovery than did subjects that spent the entire extinction-test interval in the experimental chambers and thus were tested without handling cues altogether. In Experiment 3, a group whose test for recovery began 10 min after being placed in the chambers yielded as much spontaneous recovery as did a group tested normally. Furthermore, a group for which extinction began at mid-session and for which handling therefore could not be a discriminative cue for extinction showed no more spontaneous recovery than did the other two groups. Handling cues thus contributed to spontaneous recovery only after explicit discrimination training, as provided in Experiment 1. 相似文献

We investigated how learners' motivation impacts the testing effect for complex study materials. High mastery goal orientation was expected to weaken the effect, while external rewards for successful retrieval practice were expected to strengthen it. Two experiments (N = 191) compared restudy, retrieval practice, and retrieval practice with external reward in a between-subject design. We assessed delayed retention after 1 week. Both experiments revealed a testing effect. Learners' mastery goal orientation moderated the effect in both experiments. It was strong in students with low mastery goal orientation and absent in those with high mastery goal orientation. The external reward failed to enhance the testing effect in Experiment 1, but boosted it in Experiment 2 with more specific criteria for “successful retrieval practice.” In Experiment 2, the reward increased students' retrieval practice effort, improving delayed retention. These results suggest that students' motivation to practice retrieval and to restudy are important boundary conditions for the testing effect. 相似文献

Photographs are frequently taken to preserve memories of events from the personal past, but they can also bias how we remember. For example, photographs often capture events from a novel visual perspective (e.g., seeing ourselves in the image). Here, we examined how the presence of the self in photographs influences autobiographical memories. Participants provided subjective ratings for specific autobiographical memories, and then, following the retrieval phase, they were asked to indicate whether they had photographs for these memories and the nature of these images. Across three studies (N = 378), we found that autobiographical memories that participants reported the presence of photographs containing the self were more likely to be remembered from an observer-like perspective than memories with photographs in which the self was not visible. These findings have important implications for understanding how the growing number of photographs taken in everyday life biases the perspective of our memories. 相似文献

Previous research has found that music brings back more vivid and emotional autobiographical memories than various other retrieval cues. However, such studies have often been low in ecological validity and constrained by relatively limited cue selection and predominantly young adult samples. Here, we compared music to food as cues for autobiographical memories in everyday life in young and older adults. In two separate four-day periods, 39 younger (ages 18–34) and 39 older (ages 60–77) adults recorded their music- and food-evoked autobiographical memories in paper diaries. Across both age groups, music triggered more frequent autobiographical memories, a greater proportion of involuntary memories, and memories rated as more personally important in comparison to food cues. Age differences impacted music- and food-evoked memories similarly, with older adults consistently recalling older and less specific memories, which they rated as more positive, vivid, and rehearsed. However, young and older adults did not differ in the number or involuntary nature of their recorded memories. This work represents an important step in understanding the phenomenology of naturally occurring music-evoked autobiographical memories across adulthood and provides new insights into how and why music may be a more effective trigger for personally valued memories than certain other everyday cues. 相似文献

People frequently gesture when a word is on the tip of their tongue (TOT), yet research is mixed as to whether and why gesture aids lexical retrieval. We tested three accounts: the lexical retrieval hypothesis, which predicts that semantically related gestures facilitate successful lexical retrieval; the cognitive load account, which predicts that matching gestures facilitate lexical retrieval only when retrieval is hard, as in the case of a TOT; and the motor movement account, which predicts that any motor movements should support lexical retrieval. In Experiment 1 (a between-subjects study; N = 90), gesture inhibition, but not neck inhibition, affected TOT resolution but not overall lexical retrieval; participants in the gesture-inhibited condition resolved fewer TOTs than participants who were allowed to gesture. When participants could gesture, they produced more representational gestures during resolved than unresolved TOTs, a pattern not observed for meaningless motor movements (e.g., beats). However, the effect of gesture inhibition on TOT resolution was not uniform; some participants resolved many TOTs, while others struggled. In Experiment 2 (a within-subjects study; N = 34), the effect of gesture inhibition was traced to individual differences in verbal, not spatial short-term memory (STM) span; those with weaker verbal STM resolved fewer TOTs when unable to gesture. This relationship between verbal STM and TOT resolution was not observed when participants were allowed to gesture. Taken together, these results fit the cognitive load account; when lexical retrieval is hard, gesture effectively reduces the cognitive load of TOT resolution for those who find the task especially taxing. 相似文献
