Phonetic symbolism and feeling of knowing

American subjects matched English antonym pairs with antonym pairs from Thai, Kannada, and Yoruba. For each match they also,indicated their degree of feeling of knowing (FOK). Although translation accuracy was in general better than chance, suggesting universal phonetic symbolism, it was found to vary considerably with the subject’s FOK ratings: Translations evoking stronger FOK were more likely to be correct than translations evoking weaker FOK, and matches which proved correct were assigned higher FOK ratings than matches which proved incorrect. Several implications of the finding that subjects can monitor their success in guessing the meaning of words from foreign languages are outlined.     

A new technique for investigating the feeling of knowing

Previous investigations of the feeling of knowing (FOK) have relied on absolute FOK judgements rather than on relative FOK judgments. This has resulted in a confounding of (1) the subject's metamemorial knowledge of nonrecalled items with (2) the subject's know/don't-know threshold. The new technique replaces the absolute FOK judgments with relative FOK judgments in which the subject generates (via paired comparisons) a FOK rank order of nonrecalled items in terms of the predicted likelihood of recognition. This new technique eliminates the aforementioned confounding, provides a richer data base, and yields separate estimates of FOK validity and FOK reliability.     

Body ownership: When feeling and knowing diverge

Individuals with the peculiar disturbance of ‘overcompleteness’ experience an intense desire to amputate one of their healthy limbs, describing a sense of disownership for it (Body Integrity Identity Disorder – BIID). This condition is similar to somatoparaphrenia, the acquired delusion that one’s own limb belongs to someone else. In ten individuals with BIID, we measured skin conductance response to noxious stimuli, delivered to the accepted and non-accepted limb, touching the body part or simulating the contact (stimuli approach the body without contacting it), hypothesizing that these individuals have responses like somatoparaphrenic patients, who previously showed reduced pain anticipation, when the threat was directed to the disowned limb. We found reduced anticipatory response to stimuli approaching, but not contacting, the unwanted limb. Conversely, stimuli contacting the non-accepted body-part, induced stronger SCR than those contacting the healthy parts, suggesting that feeling of ownership is critically related to a proper processing of incoming threats.     

提取干扰对不同类型内隐记忆的影响

以往研究关于提取阶段的干扰是否会影响内隐记忆存在着异义,其中一个重要因素可能源于所采用的内隐记忆测验类型的差异。本研究采用学习-测验范式,通过4个实验,分别考察了提取干扰对识别式知觉内隐测验、识别式概念内隐测验、产生式知觉内隐测验和产生式概念内隐测验的影响,以期对提取干扰和内隐记忆之间的关系有着更全面的了解。结果表明:(1)词汇判断任务(识别式知觉)和语义分类任务(识别式概念)的启动效应在提取干扰下消失了,(2)而产生式词汇判断任务(产生式知觉)和产生式语义分类任务(产生式概念)在提取干扰下仍发现了明显的启动效应,但与无干扰条件相比,启动效应量也有着明显的减少。由此可见,不同类型的内隐记忆都会受到提取干扰的影响,相比于产生式启动,识别式启动更容易受到提取干扰的破坏。     

An analysis of the determinants of the feeling of knowing

Research has demonstrated that feeling-of-knowing (FOK) judgments are affected by the amount of accessible information related to an inaccessible target. Further, studies have demonstrated that, in some situations, FOK judgment magnitude is not only related to the amount (quantity) of accessed features, but also the correctness of those features (Thomas, Bulevich, & Dubois, 2011). The present study examined the conditions under which the correctness of features would influence FOK judgment magnitude. We hypothesized that accuracy of retrieved features would influence FOK judgments, but only in situations where semantically meaningful information was accessible. In three experiments, we manipulated accessibility of semantic information. In all experiments, the quantity, or amount of retrieved partial information had a greater impact on FOK judgments than the accuracy of that information. However, in situations where semantic information was accessible, accuracy of retrieved semantic features also influenced FOK judgment magnitude, and later recognition.     

Contextual information influences the feeling of knowing in episodic memory

The feeling of knowing (FOK) predicts the likelihood of eventually recognizing currently unrecalled items. Koriat (1993, 1995) showed that retrieval of partial target information influences FOK ratings. Building on Koriat’s view, the noncriterial-recollection hypothesis contends that contextual information influences FOKs (Brewer, Marsh, Clark-Foos, & Meeks, 2010). Our study assessed the validity of the noncriterial-recollection hypothesis by controlling the amount of potentially-retrievable contextual information presented to participants. We varied the amount of contextual information accompanying the name and image of imaginary animals. There were three information conditions: minimum (name and image), medium (name, image, and country), and maximum (name, image, country, diet and weight). Information condition did not affect recall accuracy. The minimum condition resulted in greater response output (recall and commission errors together). FOKs for unrecalled items were lower in the minimum condition than the other conditions. Consistent with the noncriterial-recollection hypothesis, FOKs were positively correlated with the retrieval of contextual information.     

A comparison of three predictors of an individual's memory performance: the individual's feeling of knowing versus the normative feeling of knowing versus base-rate item difficulty

Distinctions are drawn between different predictors of an individual's memory performance, with emphasis on the notion of privileged access to idiosyncratic knowledge. Research is reported in which undergraduates attempted to recall the answers to general-information questions, then made feeling-of-knowing judgments on nonrecalled items, and subsequently had a criterion test (relearning, perceptual identification, or one of two versions of recognition). For predicting an individual's criterion performance, the individual's own feeling-of-knowing predictions were intermediate between two kinds of normative predictions: The individual's feeling-of-knowing predictions were more accurate than predictions derived from normative feeling-of-knowing ratings but were less accurate than predictions derived from base-rate item difficulty (normative probabilities of correct recall). Subsidiary analyses showed that factors other than unreliability are responsible for the partial inaccuracy of the individual's feeling of knowing. Ramifications are discussed for possible ways to improve the accuracy of an individual's feeling-of-knowing predictions.     

Judgments for inaccessible targets: Comparing recognition without identification and the feeling of knowing

Both the recognition-without-identification (RWI) and feeling-of-knowing (FOK) paradigms attempt to tap participants?? sense about a target that is inaccessible. In the case of RWI, participants judge the likelihood that the inaccessible target was studied. In the case of FOKs, participants judge the likelihood that the inaccessible target will be recognized at a later point in time. The present study compared the two using a hybrid paradigm. The patterns of responding differed depending on whether the judgment was of the RWI type or the FOK type. For the former, ratings were significantly higher for studied than for unstudied inaccessible targets (the typical RWI effect). For the latter, ratings were significantly lower for studied than for unstudied inaccessible targets (a reversal of the usual RWI effect). Similarity of the targets and distractors diminished the usual RWI effect, but not its reversal in the FOK situation, suggesting that the bases of the two effects differ. A potential explanation is that when participants judge whether an inaccessible target was presented earlier, they are oriented toward relying on cue familiarity, which should be greater for cues of studied targets, whereas when they judge whether they will recognize an inaccessible target later on, they are oriented toward relying on the accessibility of information, which is greater in the unstudied condition, due to the lack of priming of the targets.     

The influence of mood on the intensity of emotional responses: Disentangling feeling and knowing

The results of three experiments suggest that pre-existing mood increases the intensity of affectively congruent emotions while dampening the intensity of incongruent emotions independent of attributional knowledge. This result was obtained using a new method for inducing mood states unobtrusively and with minimal or no cognitive concomitants. The results of Experiment 1 revealed that for participants who were exposed to positive feedback a pre-existing positive mood led to stronger feelings of pride in comparison to negative mood. The results of Experiments 2 and 3 suggest that pre-existing mood directly influences the experience of subsequently elicited emotions independent of what one knows about the causes of this feeling. When participants were required to differentiate between the funniness of a cartoon and their subjective humour response, mood influenced only the latter judgement (Experiment 2). In Experiment 3, reminding participants of the mood induction resulted in a contrast effect in judging the funniness of a cartoon. However, the pre-existing mood continued to exert an assimilation effect on the overt mirth response. In conclusion, these results suggest that the feeling and knowledge component are partly independent bases of emotional responses.     

Divided attention at retrieval disrupts knowing but not remembering

The view that remember and know responses can be explained within a dual-process framework has recently been questioned (e.g., Gardiner, Konstantinou, Karayianni, & Gregg, 2005). The aims of the present study were to investigate further discrepancies between remember/know (R/K) studies and dual-process models of recognition memory. In two experiments participants were required to make old/new and R/K decisions under full and divided attention conditions. Experiment 1 used a two-step R/K procedure and showed that attention during retrieval reduced overall recognition performance. Experiment 2 used a one-step R/K procedure and showed that dividing attention at retrieval only affected know responses, suggesting that knowing but not remembering relies on controlled retrieval processes. These findings and findings from recent research provide evidence that is inconsistent with the dual-process explanation for R/K research.

Another look at the relationship between phonetic symbolism and the feeling of knowing

Koriat (1975), using a word-matching phonetic symbolism task, found a significant relationship between translation accuracy and the degree of subjective confidence associated with the response. This study examined the hypothesis that since responses on which subjects are in consensus are more likely correct than incorrect, confidence ratings may actually be related to the degree of consensus, regardless of the correctness of the response. The results strongly supported this hypothesis. For items with a consensually correct response, translation accuracy increased with degree of subjective confidence, while for items with a consensually incorrect response it decreased. Consensual responses were judged subjectively more compelling than nonconsensual responses regardless of their accuracy. Some implications of these findings are outlined.     

The effects of different types of retrieval cues on the recall of names of famous faces

The present study investigated the effects of cues on subjects’ abilities to retrieve the names of famous faces that they had previously been unable to recall. In Experiment 1 subjects were presented with a second photograph of the celebrity, or biographical information about the celebrity, or the celebrity’s initials. Each type of cue produced a quite different pattern of recall. Biographical information was least likely to elicit the name when the subject already knew the celebrity’s occupation, and most likely when subjects found the face familiar only. Conversely, initials were more likely to elicit the name when the occupation was already known than when the face was at first found unfamiliar or familiar only. Rather surprisingly, no significant differences were observed when a new photograph was used as a cue. In Experiment 2, the effects of a new photograph were compared with a condition in which the same photograph was presented twice. A new photograph was beneficial when subjects had previously found the face unfamiliar and when they found the face familiar only, but not when they knew the occupation. It is argued that these, as well as other aspects of the results, generally support the view that successive, but distinct stages are involved in face recognition, consistent with the model put forward by Bruce and Young (1986).     

Interfering with remembering and knowing: effects of divided attention at retrieval

A Remember-Know paradigm was used to examine the cognitive resource requirements of recollection and familiarity memory processes at retrieval. Younger and older adults studied a list of words, and in a later auditory recognition test indicated whether each word was Remembered, Known, or New. Retrieval was performed under full or divided attention (DA) conditions, with either a digit task to numbers, or an animacy task to words, presented visually. Younger and older adults showed an increase in false Remember responses during both DA conditions, indicating a general effect of attention on illusory recollection. Both age groups also showed decreased accuracy in Know responses, but only during the word-based DA condition, indicating a material-specific effect on familiarity. Aging was associated with decreased accuracy in Remember, but not Know, responses, and with increased latency in distracting task responses under DA conditions. Results suggest that avoiding false recollective responses during retrieval requires attentional resources, whereas accurate familiarity responses require the reactivation of content-specific representations.

Semantic-memory sources of episodic retrieval failure

In a cued-recall paradigm, retrieval blocking was investigated as a source of episodic retrieval failure. Each unrelated-interference (UR-I) word pair (e.g., “nurse-dollar”) had its own “competitive alternative” (e.g., “doctor’), which not only was strongly related to the cue word, but also possessed the same first two letters and final letter as did the target word. None of the unrelated-control (UR-C) word pairs (e.g., “clock-dollar”) had such an alternative. Cued recall substantially increased from the cue-word-only (e.g., “nurse- ”) to the three-letters-also cue condition (e.g., “nurse-do___r”) for the UR-C but not for the UR-I word pairs. Instead, subjects frequently reported the competitive alternatives in place of the UR-I target words in the three-letters-also cue condition. It was suggested that, relying on the primary plausibility judgment, subjects falsely accepted the competitive alternatives while the UR-I target words were blocked from retrieval by the potent retrieval of these plausible alternatives.
