The relation of tip-of-the-tongue states and retrieval time

The tip-of-the-tongue state (TOT) is the phenomenological experience that a word is on the verge of being recalled. Participants rated TOTs as either emotional or nonemotional. In Experiment 1, given general-information questions, participants spent more time attempting retrieval during emotional TOTs than during nonemotional TOTs or n-TOTs (retrieval failures not accompanied by TOTs). Experiment 2 replicated the effect that TOTs show longer retrieval times than n-TOTs. In Experiment 3, with word definitions as stimuli, retrieval times were longer for emotional TOTs. Experiment 4 showed the same relation between retrieval times and TOTs even when participants made retrospective decisions about whether they had experienced a TOT before they retrieved the correct target. Valence of emotion was correlated with correct resolution of the TOT. These results are discussed in the context of a metacognitive model, in which TOTs serve to monitor and control cognition.     

The effects of emotion on tip-of-the-tongue states

Tip-of-the-tongue states (TOTs) are judgments of the likelihood of imminent retrieval for items currently not recalled. In the present study, the relation of emotion to the experience of TOTs is explored. Emotion-inducing questions (e.g.), “What is the term for ritual suicide in Japan?”) were embedded among neutral questions (e.g., “What is the capital of Denmark?”). Participants attempted to recall the answers and, if unsuccessful, were asked if they were in a TOT and given a recognition test. For unrecalled items, there were significantly more TOTs for the emotional items than for the neutral items, even though the recognition performance was identical. There were more TOTs for questions that followed emotional questions than TOTs for questions that followed neutral questions, suggesting the emotional arousal lasts beyond the specific question. These findings suggest that emotional cues increase the likelihood of TOTs. These data are consistent with a metacognitive view of TOTs.     

Dissociation between the cognitive process and the phenomenological experience of TOT: effect of the anxiolytic drug lorazepam on TOT states

TOT states may be viewed as a temporary and reversible microamnesia. We investigated the effects of lorazepam on TOT states in response to general knowledge questions. The lorazepam participants produced more commission errors and more TOTs following commission errors than the placebo participants (although the rates did not change). The resolution of the TOTs was unimpaired by the drug. Neither feeling-of-knowing accuracy nor recognition were affected by lorazepam. The higher level of incorrect recalls produced by lorazepam participants may be due to the fact that they were more frequently temporarily unable to access a known item. For some of these items, the awareness of the retrieval failure resulted in a commission TOT (phenonemological TOT after a commission error). The resolution of the TOT conflict is discussed in the light of the anxiolytic and anticonflict effects of lorazepam. The data are discussed in terms of contemporary theories of TOTs and the effects that benzodiazepines have on semantic memory.     

Gesture Helps,Only If You Need It: Inhibiting Gesture Reduces Tip-of-the-Tongue Resolution for Those With Weak Short-Term Memory

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.     

From tip-of-the-tongue (TOT) data to theoretical implications in two steps: when more TOTs means better retrieval

Two experiments in which participants named pictured objects with difficult or easier names, and a reanalysis and review of published data, reveal that problematic measures used in previous studies obscured the implications of group differences in tip-of-the-tongue (TOT) rates. In Experiment 1, increased age led to more TOTs for difficult but not easy targets. In Experiment 2, bilinguals had more TOTs than monolinguals for easy targets but fewer TOTs for difficult targets. The authors developed a theoretically motivated measure that clarifies the implications of TOT data by linking all responses elicited in the TOT paradigm with either success or failure in completing 2 retrieval steps in current models of language production. The 2-step analysis reveals a common mechanism for the age and bilingualism effects and implies that age has both positive and negative effects on retrieval.     

Isolating phonological components that increase tip-of-the-tongue resolution

Three experiments investigated the role of specific phonological components in priming tip-of-the-tongue (TOT) resolution. When in a TOT state, participants read a list of words that included phonological primes intermixed among unrelated words. The phonological primes contained either the same first letter as the target (Experiment 1), a single syllable (first, middle, or last) of the target (Experiment 2), or the first phoneme or first syllable of the target (Experiment 3). Reading first-letter primes in Experiment 1 did not help to resolve TOTs, whereas reading first-syllable primes significantly increased word retrieval in Experiment 2. Experiment 3 replicated the results of Experiments 1 and 2 using first-phoneme primes instead of first-letter primes and using two primes instead of three, although first-syllable priming occurred only for primes read silently. The results of these experiments support a transmission deficit model, where TOTs are caused by weak connections among phonological representations and can be resolved through internal or overt production of specific phonology.     

Phonological priming effects on word retrieval and tip-of-the-tongue experiences in young and older adults

In a repetition priming paradigm, young and older participants read aloud prime words that sometimes shared phonological components with a target word that answered a general knowledge question. In Experiment 1, prior processing of phonologically related words decreased tip-of-the-tongue states (TOTs) and increased correct responses to subsequent questions. In Experiment 2, the priming task occurred only when the participant could not answer the question. Processing phonologically related words increased correct recall, but only when the participant was in a TOT state. Phonological priming effects were age invariant, although older adults produced relatively more TOTs. Results support the transmission deficit model that the weak connections among phonological representations that cause TOTs are strengthened by production of phonologically related words. There was no evidence that phonologically related words block TOT targets.     

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.     

Working memory load differentially affects tip-of-the-tongue states and feeling-of-knowing judgments

Tip-of-the-tongue states (TOTs) are judgments of the likelihood of imminent retrieval for items currently not recalled, whereas feeling-of-knowing judgments (FOKs) are predictions of successful recognition for items not recalled. The assumption has been that similar metacognitive processes dictate these similar judgments. In Experiment 1, TOTs and FOKs were compared for general information questions. Participants remembered four digits (working memory load) during target retrieval for half of the questions, and there was no memory load for the other questions. Working memory did not affect recall but decreased the number of TOTs and increased FOKs. In Experiment 2, participants maintained six digits during retrieval. TOTs decreased in the working memory condition, but FOKs remained constant. Experiment 3 replicated the results of Experiment 2 while asking for FOKs for recall. In each of the first three experiments, positive metacognitive judgments also affected working memory performance, supporting the idea that working memory and metamemory use similar monitoring processes. In Experiment 4, visual working memory did not affect TOTs or FOKs. The data support a view that TOTs and FOKs are separable metacognitive entities.     

Illusory Tip-of-the-tongue States

The tip-of-the-tongue state (TOT) is the phenomenological experience that a target word is on the verge of being recalled. An illusory TOT occurs when a person experiences a TOT, but the actual target is either unavailable, forgotten, or never learned. Illusory TOTs were induced by asking participants to answer questions that did not have correct answers. In Experiment 1, an episodic-memory paradigm, participants were shown fictional animals, some of which were accompanied by the animal's name (identified targets) and some of which were not (unidentified targets). Some participants experienced TOTs for unidentified targets. In Experiment 2, a semantic-memory paradigm, participants were asked generalinformation questions, some of which were questions with no correct answer. Every one of the 31 participants experienced at least one illusory TOT. The characteristics of illusory TOTs are discussed in light of inferential and directaccess views of TOTS.

The effect of being in a tip-of-the-tongue state on subsequent items

The tip-of-the-tongue state (TOT) is the feeling that an inaccessible item will be recalled. In the TOT induction paradigm, participants are given a list of general information questions or word definitions, and the participants indicate whether they are in a TOT for each item. The present study explored the effect that being in a TOT for one item (N) has on the recall and the likelihood of a TOT for the subsequent item (N + 1). Three experiments were conducted. All three experiments showed that TOTs do not affect the rate of recall for the next item but decrease the likelihood of a TOT for the next item. This effect extended to items occurring two items after the initial TOT (N + 2) in two experiments. Thus, TOTs are less likely to occur after another TOT than after an item not in a TOT. These data are interpreted within a metacognitive framework.     

Increased pupil dilation during tip-of-the-tongue states

Tip-of-the-tongue states (TOTs) are feelings of impending word retrieval success during a current failure to retrieve a target word. Though much is known and understood about TOT states from decades of research, research on potential psychophysiological correlates of the TOT state is still in its infancy, and existing studies point toward the involvement of neural processes that are associated with enhanced attention, motivation, and information-seeking. In the present study, we demonstrate that, during instances of target retrieval failure, TOT states are associated with greater pupillary dilation (i.e., autonomic arousal) in 91% of our sample. This is the first study to demonstrate a pupillometric correlate of the TOT experience, and this finding provides an important step toward understanding emotional attributes associated with TOT states. Mean pupil dilation also increased such that instances of target identification failure that were unaccompanied by TOT states < instances in which TOTs occurred < instances of target identification success. It is possible that TOTs reflect an intermediary state between complete target retrieval failure and full target retrieval.

Does priming specific syllables during tip-of-the-tongue states facilitate word retrieval in older adults?

This experiment investigated whether phonological priming of syllables helps resolve tip-of-the-tongue (TOT) states in young and older adults. Young, young-old, and old-old adults read general knowledge questions and responded "know," "TOT," or "don't know" accordingly. Participants then read a list of 10 words that included 3 phonological primes corresponding solely to the first, middle, or last syllable of the target word. Young and young-old adults resolved more TOTs after first-syllable primes, but old-old adults showed no increase in TOT resolution following any primes. These results indicate that presentation of the first syllable of a missing word strengthens the weakened phonological connections that cause TOTs and increases word retrieval, but not for old-old adults who experience greater deficits in the transmission of priming across these connections.     

The tip-of-the-tongue phenomenon: do experimenter-presented interlopers have any effect?

When a person is in a tip-of-the-tongue (TOT) state, they will sometimes recall a word that is similar in sound to the word they are attempting to retrieve. Woodworth (1929) argued that these interloper words both cause and sustain TOT states, whereas Brown and McNeill (1966) suggested that they are part of the process that leads to TOT resolution. Jones and Langford (1987) and Jones (1989) explicitly presented interloper words along with definitions of words that subjects were asked to recall. They reported that interlopers that were phonologically related to the target word increased the incidence of TOTs and concluded that this supported Woodworth's position. In three experiments, we adopted the interloper paradigm, but also included a control group who heard the definitions without interloper words. In Experiment 1, the definitions that Jones used with phonological interlopers created more TOTs even when no interlopers were presented. In Experiments 2a and 2b, we matched definitions for the number of TOTs they produced in the absence of interlopers. Under these circumstances we found no effect of interloper words at all. We conclude that there is no evidence from this paradigm to support the idea that interloper words are involved in either the causation or resolution of TOTs.     

舌尖效应产生和解决的词汇提取年老化机制：两阶段范式研究

Sparkling at the end of the tongue: the etiology of tip-of-the-tongue phenomenology

The tip-of-the-tongue experience (TOT) is the phenomenological experience that a currently inaccessible word is stored in memory and will be retrieved. TOTs appear to be a universal experience that occurs frequently in everyday life, making the TOT an ideal case study in human phenomenology. This paper considers TOTs in light of Tulving's (1989) challenge to the doctrine of concordance, which is the assumption that behavior, cognition, and phenomenology are correlated, if not caused by identical processes. Psycholinguistic and memory theories, consistent with concordance, argue for direct access, or the view that TOTs and word retrieval are caused by the same retrieval processes. The metacognition view challenges concordance and views TOTs as an inference based on nontarget information that is accessible to rememberers. Current data, reviewed here, suggest that TOTs are caused via direct access and through inferential processes. Dissociations between TOTs and retrieval suggest that the causes of TOT phenomenology and the processes of retrieval are not identical.     

Tip-of-the-tongue states reveal age differences in the syllable frequency effect

Syllable frequency has been shown to facilitate production in some languages but has yielded inconsistent results in English and has never been examined in older adults. Tip-of-the-tongue (TOT) states represent a unique type of production failure where the phonology of a word is unable to be retrieved, suggesting that the frequency of phonological forms, like syllables, may influence the occurrence of TOT states. In the current study, we investigated the role of first-syllable frequency on TOT incidence and resolution in young (18-26 years of age), young-old (60-74 years of age), and old-old (75-89 years of age) adults. Data from 3 published studies were compiled, where TOTs were elicited by presenting definition-like questions and asking participants to respond with "Know," "Don't Know," or "TOT." Young-old and old-old adults, but not young adults, experienced more TOTs for words beginning with low-frequency first syllables relative to high-frequency first syllables. Furthermore, age differences in TOT incidence occurred only for words with low-frequency first syllables. In contrast, when a prime word with the same first syllable as the target was presented during TOT states, all age groups resolved more TOTs for words beginning with low-frequency syllables. These findings support speech production models that allow for bidirectional activation between conceptual, lexical, and phonological forms of words. Furthermore, the age-specific effects of syllable frequency provide insight into the progression of age-linked changes to phonological processes.

Tip-of-the-tongue (TOT) states: retrieval,behavior, and experience

The tip-of-the-tongue state (TOT) is the feeling that accompanies temporary inaccessibility of an item that a person is trying to retrieve. TOTs have been studied experimentally since the seminal work of Brown and McNeill (1966). TOTs are experiences that accompany some failed or slow retrievals, and they can result in changes in retrieval behavior itself, allowing us to study the interplay among experience, retrieval, and behavior. We often attribute the experience of the TOT to the unretrieved target, but TOTs are based on a variety of cues, heuristics, or sources of evidence, such as partial information, related information, and cue familiarity, that predict the likelihood of overcoming retrieval failure. We present a synthesis of the direct-access view, which accounts for retrieval failure, and the heuristic–metacognitive view, which accounts for the experience of the TOT. We offer several avenues for future research and applications of TOT theory and data.
