Effects of self-referencing on feeling-of-knowing accuracy and recollective experience

The current research investigated the impact of self-referencing (SR) on feeling-of-knowing (FOK) judgements to improve our understanding of the mechanisms underlying these metamemory judgements and specifically test the relationship between recollective experiences and FOK accuracy within the accessibility framework FOK judgements are thought to be by-products of the retrieval process and are therefore closely related to memory performance. Because relating information to one's self is one of the factors enhancing memory performance, we investigated the effect of self-related encoding on FOK accuracy and recollective experience. We compared performance on this condition to a separate deep processing condition in which participants reported the frequency of occurrence of pairs of words. Participants encoded pairs of words incidentally, and following a delay interval, they attempted at retrieving each target prompted by its cue. Then, they were re-presented with all cues and asked to provide FOK ratings regarding their likelihood of recognising the targets amongst distractors. Finally, they were given a surprise recognition task in which following each response they identified whether the response was remembered, known or just guessed. Our results showed that only SR at encoding resulted in better memory, higher FOK accuracy and increased recollective experience.     

Feeling of knowing for names in response to faces

Participants were asked to recall the names when shown photographs of faces in both a semantic task (Experiment 1) and an episodic task (Experiments 2 and 3). When recall failed, feeling of knowing (FOK) ratings were solicited. In addition, participants reported on the strategies that they used to make their ratings, whether they could recall other pieces of information (the target-accessibility strategy, e.g., Koriat, A. (1993). How do we know that? The accessibility model of the feeling of knowing. Psychological Review, 100, 609–639) or whether the faces simply looked familiar (the cue-familiarity strategy, e.g., Schwartz, B. L., & Metcalfe, J. (1992). Cue familiarity but not target accessibility enhances feeling of knowing ratings. Journal of Experimental Psychology: Learning, Memory, and Cognition, 18, 1074–1083). In all experiments, FOK ratings were fairly accurate in that participants were successful in predicting their performance on a subsequent recognition test. More importantly, participants reported using the cue-familiarity strategy more often, although they gave higher FOK ratings when they reported using the target-accessibility strategy. The FOK ratings that were given using the two strategies were equally accurate.     

Differentiating falsely recognized faces from incompletely remembered faces

This study describes an experimental method for determining whether people who recognize a face containing both some target features and some new features are falsely recognizing the face or whether they are incompletely remembering it. Twenty min. after studying a target face either one time or a third time, 136 participants were instructed to examine six test faces similar to the target and to select two test faces sharing only target features and no unstudied features. The likelihood of selecting two test faces sharing four target features and no incorrect features was significantly greater than chance only for the 67 participants who studied the target three times. Because the two faces selected as containing only target features did not share any unstudied features, they were not falsely recognized; instead, they were indicative of correct but incomplete memory for the thrice-studied target.     

The role of familiarity in episodic memory and metamemory for music

Participants heard music snippets of varying melodic and instrumental familiarity paired with animal-name titles. They then recalled the target when given either the melody or the title as a cue, or they gave name feeling-of-knowing (FOK) ratings. In general, recall for titles was better than it was for melodies, and recall was enhanced with increasing melodic familiarity of both the cues and the targets. Accuracy of FOK ratings, but not magnitude, also increased with increasing familiarity. Although similar ratings were given after melody and title cues, accuracy was better with title cues. Finally, knowledge of the real titles of the familiar music enhanced recall but had, by and large, no effect on the FOK ratings.     

Revelation effect in metamemory

Test items are more likely to be judged as previously studied if they need to be discovered before the recognition decision. In the present experiments, this revelation effect was extended to metamemory judgments. Participants studied word pairs and then tried to recall the second word of each pair when given the first word as a cue. In Experiment 1, a fragment of the target was either gradually increased in size or held constant, and in Experiment 2, sometimes an anagram of the cue was given instead of the cue itself. Thus, for some items, there was a revelation task before a recall attempt. If recall failed, the participants gave feeling-of-knowing (FOK) ratings. In both experiments, the participants gave higher FOK ratings after a revelation task, even though the items that these FOKs referred to remained unrecalled. Analyses showed a criterion shift but no differences in sensitivity.     

Recognition without picture identification: Geons as components of the pictorial memory trace

Participants viewed a list of black-and-white line drawings and were then presented with a picture fragment identification task in which half of the fragments corresponded to studied pictures and half corresponded to unstudied pictures. In addition to trying to identify each picture fragment, participants gave a rating to indicate the likelihood that the fragment came from a studied picture. When participants could not identify the picture fragments, they were still able to discriminate between fragments that came from studied pictures and fragments that came from unstudied pictures (as shown by their recognition ratings), but only when the fragments contained information about the geometric components (geons) that underlay the original pictures. No recognition without identification was found when the fragments contained only line segment information.     

Effects of target set sizeon feelings of knowing and cued recall: Implications for the cue effectiveness andpartial-retrieval hypotheses

Target set size refers to the number of preexisting connections a studied word has to closely related concepts in long-term memory. The purpose of this investigation was to determine whether target set size influences feeling-of-knowing (FOK) ratings. The results showed that ratings were higher for targets connected to smaller sets, as compared with those connected to larger sets. Comparable effects were obtained with the use of different encoding strategies, including concreteness classifications and vowel naming, and with both meaningfully and phonologically related test cues. These findings indicate that FOKsare sensitive to competition between concepts linked to the target and that this sensitivity is independent of encoding strategy and type of test cue. Response time measures indicated that FOKs are sensitive to competition that arises when concepts are activated in parallel, whereas recall is more sensitive to competition that arises during sampling associated with search. Implications for various cue-based and target-based explanations of FOK effects are discussed.     

The use of cue familiarity during retrieval failure is affected by past versus future orientation

Cue familiarity that is brought on by cue resemblance to memory representations is useful for judging the likelihood of a past occurrence with an item that fails to actually be retrieved from memory. The present study examined the extent to which this type of resemblance-based cue familiarity is used in future-oriented judgments made during retrieval failure. Cue familiarity was manipulated using a previously-established method of creating differing degrees of feature overlap between the cue and studied items in memory, and the primary interest was in how these varying degrees of cue familiarity would influence future-oriented feeling-of-knowing (FOK) judgments given in instances of cued recall failure. The present results suggest that participants do use increases in resemblance-based cue familiarity to infer an increased likelihood of future recognition of an unretrieved target, but not to the extent that they use it to infer an increased likelihood of past experience with an unretrieved target. During retrieval failure, the increase in future-oriented FOK judgments with increasing cue familiarity was significantly less than the increase in past-oriented recognition judgments with increasing cue familiarity.     

Relating familiarity-based recognition and the tip-of-the-tongue phenomenon: Detecting a word’s recency in the absence of access to the word

After viewing a list of single-word answers to general knowledge questions, participants received a test list containing general knowledge questions, some of whose answers were studied, and some of whose were not. Regardless of whether participants could provide the answer to a test question, they rated the likelihood that the answer had been studied. Across three experiments,participants consistently gave higher ratings to unanswerable questions whose answers were studied than to those whose answers were not studied. This discrimination ability persisted in the absence of reported tip-of-the-tongue (TOT) states and when no information about the answer could be articulated. Studying a question's answer did not increase the likelihood of a later TOT state for that question, yet participants gave higher recognition ratings when in a TOT state than when not in a TOT state. A possible theoretical mechanism for the present pattern is discussed, as are relevant theories of familiarity-based recognition and of the TOT phenomenon.     

The Effects of Expertise on the Hindsight Bias

We present data from three experiments examining the effects of objective and subjective expertise on the hindsight bias. In Experiment 1, participants read an essay about baseball or dogs and then answered questions about the baseball essay to the best of their ability, as if they had not read the essay, or to the best of their ability, although they read about dogs. Participants also completed a quiz about baseball rules and terminology, which was an objective measure of expertise. Results demonstrated that as participants' baseball expertise increased, their inability to act as if they never read the essay also increased; expertise exacerbated the hindsight bias. To test the effects of subjective expertise on hindsight bias and investigate factors underlying the relationship, participants in Experiment 2 ranked five topics in order of expertise and gave feeling‐of‐knowing (FOK) ratings for questions from these topics. Foresight participants then saw each question again and answered the questions; hindsight participants saw the questions and answers and gave the probability they would have known the answers had they not been provided. Hindsight bias increased with subjective expertise as did average FOK ratings. In Experiment 3, we experimentally manipulated perceived expertise but found that neither average FOK ratings nor hindsight bias was affected by experimentally induced expertise. Taken together, the results demonstrate that expertise exacerbates both objective and subjective hindsight bias but that an FOK, which likely exists only when expertise is naturally acquired, is necessary to engender the detrimental effect of expertise on the hindsight bias.

The effects of degree of learning,meaning, and invidual differences on the feeling-of-knowing

Research on the feeling-of-knowing (FOK) phenomenon has established it as a valid indicator of the contents of memory and a reliable predictor of subsequent performance. It has been shown that degree of prior learning of items is one factor upon which FOK is based — the ‘overlearning’ effect. The present study was designed to determine, firstly, whether the overlearning effect is due to different numbers of presentations of physical attributes during learning, to encoding variability, or to both, and secondly, whether individual differences in the cognitive style variable of category width affect FOK judgments or accuracy. Using a delayed recall-FOK judgment-recognition paradigm, measures on these tests were obtained from narrow and broad categorizers, who learned paired-associate items to a criterion of 1 or 3 correct recalls. The target item, a homograph, to be produced in response to the cue, a number, was learned either as a word of single or multiple meaning. Results showed that a greater degree of learning did not increase FOK magnitude or accuracy, although it did increase recall and overall recognition. On the other hand, category width and encoding variability did not affect recall and recognition, but did influence magnitude and accuracy of FOK: Broad categorizers gave higher FOK ratings than narrow, and when single meanings of the target only were learned, broad categorizers gave higher ratings than narrow. This finding was not replicated in the accuracy of FOK responses: Broad categorizers were more accurate for multiple target encoding but less accurate for single. Thus FOK is influenced by semantic aspects of the target in different ways by subjects exhibiting different cognitive styles. The study places FOK firmly in the metamemory domain.     

Sexual Double Standards: Bias in Perceptions of Cyber-Infidelity

The current study compared the predictions of two socio-cultural theories, shifting standards and intergroup bias, to predict sexual double standards that occur in reactions to computer-mediated infidelity. Shifting standards theory (Biernat In The shifting standards model: Implications of stereotype accuracy for social judgment, APA, Washington DC, 1995) suggests that individuals will judge female targets more harshly than male targets, based on culturally ingrained stereotypes regarding sexual behavior. On the contrary, intergroup bias theory (Brewer In Psychol Bull 86:307–324, 1979) predicts that individuals will judge outgroup targets, or members of the opposite sex, more harshly than ingroup targets, or members of the same sex. Participants were shown a hard copy of presumable evidence that extradyadic computer-mediated behavior had occurred, engaged in by one of two members of a couple. The two groups differed only by the sex of the target, the female “Colleen” or the male “Bill”. Then participants reported their attitudes toward the target’s behavior, resulting distress, and likelihood to terminate the relationship. Results showed support for the intergroup bias theory, suggesting that individuals altered their attitudes toward the behavior based on whether the target was an ingroup or outgroup member.     

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.     

Subjective states associated with retrieval failures in Parkinson’s disease

Instances in which we cannot retrieve information immediately but know that the information might be retrieved later are subjective states that accompany retrieval failure. These are expressed in feeling-of-knowing (FOK) and Tip-of-the-tongue (TOT) experiences. In Experiment 1, participants with Parkinson’s disease (PD) and older adult controls were given general questions and asked to report when they experienced a TOT state and to give related information about the missing word. The PD group experienced similar levels of TOTs but provided less correct peripheral information related to the target when in a TOT state. In Experiment 2, participants were given a Semantic (general knowledge questions) and an Episodic (word pairs) FOK task. PD patients failed to accurately predict their future memory performance (FOK) in response to both episodic and semantic cues. Results are interpreted in the context of recent frameworks of memory and metacognition.     

空间距离对视觉工作记忆巩固的影响

以往研究发现,个体对不同类型的视觉信息进行视觉工作记忆巩固的模式存在差异,如对于方向信息,一次只能有一个项目被巩固进入视觉工作记忆系统,而对于颜色信息,个体则可以一次巩固两个项目进入视觉工作记忆系统。但对于视觉信息的巩固模式是否会受其他因素的影响,目前仍然没有明确的定论。本研究将探讨视觉信息的巩固模式是否可能受到记忆项目空间距离因素的影响。研究采用变化觉察范式、序列-同时呈现操作及控制记忆项目呈现间距的方法,通过3个实验考察记忆项目之间的空间距离是否能够影响个体对颜色信息和方向信息的巩固模式。在三种空间距离水平上序列呈现或同时呈现两个记忆项目,实验结果一致发现记忆项目之间的空间距离会对视觉工作记忆巩固模式产生明显影响,个体在同时呈现条件下的正确率会随着空间距离的增大而降低。这些结果表明对同一类视觉信息进行巩固的过程中所存在的项目数量限制并不是固定的,个体可以采用序列模式或有限容量的并行模式对同一类信息进行巩固,巩固的模式可能与视觉空间注意的分配以及视觉信息所能获得的注意资源有关。     

How people make support judgments: individual differences in the traits used to infer supportiveness in others.

Social support and other social judgments are composed of several distinct components, of which relationship effects are an important part. With regard to support judgments, relationship effects refer to the fact that when judging the same targets, people differ systematically in whom they see as supportive. One explanation for this effect is that people differ in how they combine information about targets to judge supportiveness. Participants rated the supportiveness of hypothetical targets and targets from their own social networks. Multilevel modeling identified the traits participants used to make support judgments. There were significant differences in the extent to which participants used different target personality traits to judge supportiveness. In addition, participant neuroticism predicted the extent to which participants used target neuroticism and agreeableness to judge supportiveness.     

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.     

The components of sexual orientation, religiosity, and heterosexuals' impressions of gay men and lesbians

In 2 studies, the authors explored whether emphasizing the sexual behavior of gay men and lesbians influences heterosexuals' impressions of gay male and lesbian targets. In both studies, participants read short vignettes of heterosexual and gay male or lesbian targets that described their sexual histories using information restricted to only 1 component of sexual orientation (emotion, behaviors, or fantasies). The results of Study 1 showed that participants rated a behavioral gay male target more negatively than they did the emotions and fantasy targets, and this difference was a function of participant religiosity. In Study 2, participants rated the behavioral lesbian target more negatively than they did the emotions and fantasy targets; however, these differential ratings of the lesbian targets were not affected by participant religiosity.     

Context affects feeling-of-knowing accuracy in younger and older adults

In feeling of knowing (FOK) studies, participants predict subsequent recognition memory performance on items that were initially encoded but that cannot presently be recalled. Research suggests that FOK judgment magnitude may be influenced by the total amount, or quantity, of contextual information retrieved related to the unrecalled target (e.g., Koriat, 1993). The present study examined the contribution of quality of that information to episodic FOK judgments. In addition, we tested whether the episodic FOK deficit demonstrated by older adults could be reduced by encouraging retrieval of contextual information relevant to the target. Three experiments demonstrated that quality of the retrieved partial information influenced FOK judgments in both older and younger adults; however, the manifestation of that influence was age dependent. The results also indicated that older adults required explicit retrieval of contextual information before making FOK judgments in order to make accurate FOK predictions. The results suggest that FOK accuracy may be partially determined by search processes triggered when participants are queried for contextual information.     

Name or hum that tune: Feeling of knowing for music

This is the first reported research that explores the feeling of knowing (FOK) for musical stimuli. Subjects attempted to recall melodies and titles of musical pieces, made FOK ratings when recall failed, and then had a recognition test. With instrumental music (Experiment 1), more titles were recalled when melodies were given as cues than vice versa. With songs whose lyrics were not presented (Experiment 2), however, more melodies were recalled than were titles. For nonrecalled items, although the overall levels of recognition did not differ, FOK ratings were higher for titles than for melodies in Experiment 1, and the opposite pattern occurred in Experiment 2. In both experiments, the FOK ratings predicted melody recognition more accurately than they did title recognition.
