Measures of free recall of 900 English nouns: Correlations with imagery,concreteness, meaningfulness,and frequency

Forty groups of subjects were given six lists of 25 nouns each for immediate free written recall. A measure of free recall was thereby obtained for each of 900 nouns in the Paivio, Yuille, and Madigan (1968) norms, each noun’s measure based on the recall of 32 subjects. First-order correlations showed recall to be correlated with imagery, concreteness, meaningfulness, Thorndike-Lorge frequency, and Kuěra-Francis frequency. Partial correlations showed meaningfulness to be essentially unrelated to recall and concreteness only moderately related. In contrast to previous comparisons, which were based on smaller ranges of frequency and were more susceptible to list-specific effects, imagery and frequency were found to be approximately equal in their influence on free recall.     

Age-of-acquisition,imagery, familiarity and meaningfulness norms for 543 words

The age at which words are first learned appears to be more influential in determining the ease of retrieving words from semantic memory than objective frequency, familiarity, imagery, and meaningfulness. To facilitate research on a wider variety of tasks, we present norms for 543 words for age-of-acquisition, imagery, familiarity, and meaningfulness. Most of the words form single-solution anagrams. There are 471 six-letter nouns and 72 five-letter words. Also reported are the means, SDs, and ranges for each dimension and the intercorrelations between dimensions. Intergroup reliabilities ranged from .847 to .982.     

First-order approximation to English,second-order approximation to English,and orthographic neighbor ratio norms for 925 nouns

First- and second-order approximations to English and orthographic neighbor ratio values are provided for Paivio, Yuille, and Madigan’s (1968) 925 nouns. First- and second-order approximations to English are information theory measures of the probability of generating a word on a letter-by-letter basis. The orthographic neighbor ratio is the frequency of a word divided by the sum of the frequencies of all words that can be generated by changing one of its letters. Thus, the orthographic neighbor ratio provides a measure of a sophisticated guessing model in which partial information about a word is obtained and a decision is made on the basis of the relative frequencies of the possible responses. Correlations with existing norms are reported.     

Predicting which words get recalled: Measures of free recall,availability, goodness,emotionality, and pronunciability for 925 nouns

To investigate the properties that make a word easy to recall, we added to existing norms for 925 nouns measures of availability, goodness, emotionality, pronunciability, and probability of recall in multiple-trial free recall. Availability, imagery, and emotionality were found to be the best predictors of which words were recalled. This result, which is stable across recall data collected in three separate laboratories, argues for the importance of availability as a predictor of recall and questions the role of the correlated variables of word frequency and meaningfulness. Consistent with earlier work on a smaller sample of words, six factors describe the numerous properties of words studied by psychologists. The six factors are composed of variables based on orthography, imagery and meaning, word frequency, recall, emotionality, and goodness.     

Imagery,concreteness, age-of-acquisition,familiarity, and meaningfulness values for 205 five-letter words having single-solution anagrams

Solution-word imagery appears to affect difficulty of anagram solving. To assist research in this area, we present imagery, concreteness, age-of-acquisition, familiarity, and meaningfulness values for 205 five-letter words known to form single-solution anagrams. None of the words have repeated letters. Intergroup reliabilities were satisfactory on all attributes. Significant correlations were found with previous word lists and the intercorrelations between dimensions matched previous findings.     

Word norms for blind and sighted subjects: Familiarity,concreteness, meaningfulness,imageability, imagery modality,and word associations

Normative values for word characteristics were obtained from a sample of 12 college-educated, totally congenitally blind subjects on the basis of their ratings of 161 nouns on scales of familiarity, concreteness, meaningfulness, and imageability. The dominant modality of imagery for each image-evoking word and the strongest word associate for each item also were recorded. The same data were collected for a group of sighted subjects, both to provide a comparison group for the blind subjects and to test the comparability of sighted subjects’ ratings with existing norms. Ratings for sighted subjects correlated strongly with those norms, although the coefficients were slightly higher for ratings of concreteness and imageability than for ratings of familiarity and meaningfulness. Ratings of blind subjects correlated only slightly lower with existing norms for imagery and concreteness, but considerably lower for familiarity and meaningfulness.     

Norms of subjective frequency of use and imagery for a sample of 1,916 French nouns.

Norms of rated subjective frequency of use and imagery on seven-point scales are reported for 1,916 French nouns. Subjective frequency was defined as the rated frequency of occurrence of words in spoken French, and imagery was defined as the rated case with which a word aroused a mental image. The mean, standard deviation, and percentile rank of the frequency and imagery ratings for each item are presented in the Appendix together with their objective frequency of occurrence in Baudot's (1992) dictionary. Interjudge reliability was assessed by calculating the correlation between the mean ratings of items repeated in the booklet, between the mean ratings obtained from odd-numbered and even-numbered respondents, and by computing the Cronbach alpha statistic for each page of the booklet. These reliability estimates were equal to or greater than .92 for frequency and for imagery, confirming the high level of interjudge consistency. Although the estimates provided by female and male participants were highly correlated (r = .97), the former gave a slightly higher frequency rating to the word sample but a slightly lower imagery rating than the latter did. Moreover, female respondents gave slightly more extreme ratings on the frequency and imagery scales. An analysis of the absolute difference between female and male ratings revealed a discrepancy of one half point or more on 20% of the word sample for frequency and 13% for imagery. On both scales, the mean absolute difference between male and female ratings was larger than that obtained by chance alone. This finding highlights the possibility that some words may not be equally familiar to women and men or may not evoke imagery with the same ease in these groups. Validity estimates for the frequency and imagery ratings were derived from correlations with scale values drawn from other normative studies. These correlation coefficients were equal to or greater than .78 for frequency and .86 for imagery, confirming the high level of consistency between this and other studies. An analysis of the relationship between subjective frequency and imagery ratings indicated that these variables are generally uncorrelated but exceptions occur. In the present study the coefficient of the correlation between subjective frequency and imagery was .24. However, when items with extreme mean frequency were excluded from the calculation, the correlation coefficient dropped to .04 and was no longer significant. Imagery ratings from five independent studies were all positively and significantly correlated with Vikis-Freibergs's (1974) frequency estimates, which were obtained from a free-association task. This finding suggests that word association, as a form of cued recall, may be influenced by several stimulus attributes including prior frequency of association and imagery-evoking value. The pattern of correlation between imagery ratings and text-based frequency estimates is not coherent. It reveals significant correlations only in select cases and no consistent polarity of linear relationship. The main contribution of this research is to provide reliable estimates of subjective frequency and imagery value for a word sample that is larger than those included in previous studies. A close examination of the linear relationship among the various sources of frequency and imagery data underscores the risk of confounding these variables in the selection of lexical stimuli for research.     

Metamemory for faces, names, and common nouns

This study examined the metacognitive aspects of face–name learning with the goal of providing a comprehensive profile of monitoring performance during this task. Four types of monitoring judgments were solicited during encoding and retrieval of novel face–name associations. Across all of the monitoring judgments, relative accuracy was significantly above chance for face and name targets. Furthermore, metamemory performance was similar between both target conditions, even though names were more difficult to recognize than faces. As a preliminary test of the stability of monitoring accuracy across different categories of stimuli, we also compared metamemory performance between face–name pairs and noun–noun pairs. Prospective monitoring accuracy was similar across the categories of stimuli, but retrospective monitoring accuracy was superior for noun targets compared with face or name targets. Altogether, our results indicate that participants can monitor their memory for face–name associations at a level above chance, and retrospective monitoring is more accurate with nouns compared with faces and names.     

Concreteness and imageability

Previous research has shown that the positive effect of imageability upon recall is confined to abstract items. In Experiment I it was found that imageability would affect the recall of concrete items if subjects were instructed to use imagery in their memorizing. This suggested that imagery is not usually employed in remembering concrete items. In Experiment II subjects were asked to categorize items on the basis of their meaning. A majority showed sorting related to the concreteness of the items, but very few showed sorting related to imageability. In Experiment III it was found that the concreteness of an item correlated with the time taken to produce a free associate to it, but that its imageability did not. It was concluded that concreteness is a feature of lexical organization, and not a measure of the image-arousing quality of verbal material.     

Language, thought, and real nouns

We test the claim that acquiring a mass-count language, like English, causes speakers to think differently about entities in the world, relative to speakers of classifier languages like Japanese. We use three tasks to assess this claim: object-substance rating, quantity judgment, and word extension. Using the first two tasks, we present evidence that learning mass-count syntax has little effect on the interpretation of familiar nouns between Japanese and English, and that speakers of these languages do not divide up referents differently along an individuation continuum, as claimed in some previous reports [Gentner, D., & Boroditsky, L. (2001). Individuation, relativity, and early word learning. In M. Bowerman, & S. Levinson (Eds.), Language acquisition and conceptual development (pp. 215-256). Cambridge University Press]. Instead, we argue that previous cross-linguistic differences [Imai, M., & Gentner, D. (1997). A cross-linguistic study of early word meaning: Universal ontology and linguistic influence. Cognition, 62, 169-200] are attributable to “lexical statistics” [Gleitman, L., & Papafragou, A. (2005). Language and thought. In K. Holyoak, & R. Morrison (Eds.), Cambridge handbook of thinking and reasoning (pp. 633-661). Cambridge University Press]. Speakers of English are more likely to think that a novel ambiguous expression like “the blicket” refers to a kind of object (relative to speakers of Japanese) because speakers of English are likely to assume that “blicket” is a count noun rather than a mass noun, based on the relative frequency of each kind of word in English. This is confirmed by testing Mandarin-English bilinguals with a word extension task. We find that bilinguals tested in English with mass-count ambiguous syntax extend novel words like English monolinguals (and assume that a word like “blicket” refers to a kind of object). In contrast, bilinguals tested in Mandarin are significantly more likely to extend novel words by material. Thus, online lexical statistics, rather than non-linguistic thought, mediate cross-linguistic differences in word extension. We suggest that speakers of Mandarin, English, and Japanese draw on a universal set of lexical meanings, and that mass-count syntax allows speakers of English to select among these meanings.     

Meaningfulness values of words: relation to concreteness, imagery, emotionality, and interest.

We estimated that, contrary to previous studies, there was a positive correlation between ratings of meaningfulness and of emotionality of words. The correlation was .36 between ratings of meaningfulness and emotionality obtained by Campos and González but .03 with ratings obtained in 1990 by Campos. Hypothesized positive correlations for ratings of meaningfulness with ratings of concreteness, imagery, and interest were significant.     

Concreteness and word production

Two experiments are reported that investigated the effect of concreteness on the ability to generate words to fit sentence contexts. When participants attempted to retrieve words from dictionary definitions in Experiment 1, abstract words were associated with more omissions and more alternates than were concrete words. These findings are consistent with the view that the semantic–lexical weights in the word production system are weaker for abstract than for concrete words. We found no evidence that greater competition from semantic neighbors was an additional reason why abstract words were harder to produce. Participants also reported more positive tip-of-the-tongue states (TOTs) when attempting to produce abstract words from their definitions, consistent with more phonological retrieval problems for abstract than for concrete words. In Experiment 2, participants attempted to generate words to fit into a sentence that described a specific event. The difference between the numbers of abstract and concrete words recalled was significantly smaller in the event condition than in the definition condition, and evidence no longer emerged of greater phonological retrieval failure for abstract words. Overall, the results are consistent with the view that the semantic–lexical weights, but not the lexical–phonological weights, are weaker for abstract than for concrete words in the word production system.     

Mass nouns,vagueness and semantic variation

The mass/count distinction attracts a lot of attention among cognitive scientists, possibly because it involves in fundamental ways the relation between language (i.e. grammar), thought (i.e. extralinguistic conceptual systems) and reality (i.e. the physical world). In the present paper, I explore the view that the mass/count distinction is a matter of vagueness. While every noun/concept may in a sense be vague, mass nouns/concepts are vague in a way that systematically impairs their use in counting. This idea has never been systematically pursued, to the best of my knowledge. I make it precise relying on supervaluations (more specifically, ‘data semantics’) to model it. I identify a number of universals pertaining to how the mass/count contrast is encoded in the languages of the world, along with some of the major dimensions along which languages may vary on this score. I argue that the vagueness based model developed here provides a useful perspective on both. The outcome (besides shedding light on semantic variation) seems to suggest that vagueness is not just an interface phenomenon that arises in the interaction of Universal Grammar (UG) with the Conceptual/Intentional System (to adopt Chomsky’s terminology), but it is actually part of the architecture of UG.     

Concreteness of thinking and self-focus

The present study used the experience sampling method to detect fluctuations in thinking, such as self-focus or concreteness in daily life, and to examine their relationship with depressive symptoms and concurrent negative affect. Thirty-one undergraduates recorded their negative affect, ruminative self-focus, and concreteness of thinking eight times a day for 1 week. Multilevel modeling showed that individuals with increasing levels of depression showed lower levels of concreteness in their daily thinking. Further analysis revealed a significant positive association between momentary ruminative self-focus and concurrent negative affect only with low concreteness of thinking. These results suggested that individuals with increasing levels of depression chronically process self-related information on an abstract level, which reflects a malfunction of their self-regulatory cycle and might serve to maintain or even exacerbate dysphoric moods.
