Cognitive,Emotional, and Language Processes in Disclosure

Previous studies have found that writing about upsetting experiences can improve physical health. In an attempt to explain this phenomenon, 72 first-year college students were randomly assigned to write about either their thoughts and feelings about coming to college or about superficial topics for three consecutive days. Measures of language use within the writing samples and cognitive measures of accessibility and schematic organisation were collected in the weeks before and after writing. As in previous studies, writing about college was found to reduce health centre visits for illness and to improve subjects' grade point average. Text analyses indicated that the use of positive emotion words and changes in words suggestive of causal and insightful thinking were linked to health change. Improved grades, although not linked to these language dimensions, were found to correlate with measures of schematic organisation of college-relevant themes. Implications for using written language to understand cognitive and health processes are discussed.     

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.     

Subchance perception: Anxious,non-defensive individuals identify subliminally-presented positive words at below-chance levels

People who chronically experience anxiety are biased towards subliminally-presented negative information. Recent research has shown that they may also avoid subliminally-presented positive information. However, these findings are equivocal due to the limitations of previous paradigms and measures. This paper reports two experiments demonstrating that highly anxious, non-defensive individuals exhibit subchance perception when attempting to identify subliminally-presented positive words; that is, they identify such words with accuracy rates that are below chance (guessing). Participants attempted to identify masked positively and negatively valenced words that had been presented briefly (6.4 ms) in a two-alternative forced-choice paradigm. In Experiment 1, persons high in trait anxiety and low in defensiveness identified positive words at below-chance levels and negative words at above-chance levels. No other participant-group’s performance differed from chance. In Experiment 2, persons high in trait anxiety and low in defensiveness again exhibited subchance perception of positive words when responding quickly. This represents the clearest evidence to date that anxious, non-defensive individuals systematically avoid subliminally-presented positive information.

Taboo,emotionally valenced,and emotionally neutral word norms

Although taboo words are used to study emotional memory and attention, no easily accessible normative data are available that compare taboo, emotionally valenced, and emotionally neutral words on the same scales. Frequency, inappropriateness, valence, arousal, and imageability ratings for taboo, emotionally valenced, and emotionally neutral words were made by 78 native-English-speaking college students from a large metropolitan university. The valenced set comprised both positive and negative words, and the emotionally neutral set comprised category-related and category-unrelated words. To account for influences of demand characteristics and personality factors on the ratings, frequency and inappropriateness measures were decomposed into raters’ personal reactions to the words versus raters’ perceptions of societal reactions to the words (personal use vs. familiarity and offensiveness vs. tabooness, respectively). Although all word sets were rated higher in familiarity and tabooness than in personal use and offensiveness, these differences were most pronounced for the taboo set. In terms of valence, the taboo set was most similar to the negative set, although it yielded higher arousal ratings than did either valenced set. Imageability for the taboo set was comparable to that of both valenced sets. The ratings of each word are presented for all participants as well as for single-sex groups. The inadequacies of the application of normative data to research that uses emotional words and the conceptualization of taboo words as a coherent category are discussed.

Latent structure in measures of associative,semantic, and thematic knowledge

There has been much debate about the relation between knowledge for meaning (semantic memory) and knowledge for words in context (associative memory). Many measures of that knowledge exist, but do they all measure the same thing? In this study, scaling, clustering, and factor-analytic techniques were used to reveal the structure underlying 13 variables. Semantic similarity determined from lexicographic measures is shown to be separable from the associative strength determined from word association norms, and these semantic and associative measures are in turn separable from abstract representations derived from computational analyses of large bodies of text. The three-factor structure is at odds with traditional views of word knowledge. The expression of long-term knowledge about words and the concepts they represent may be better viewed in terms of associative, semantic, and thematic information.     

Objective-AoA norms for 175 names in Spanish: relationships with other psycholinguistic variables,estimated AoA,and data from other languages

There is a large body of evidence suggesting that words learnt early in life are recognised and produced faster than words learnt later in life, even when other variables are controlled. This is known as the Age of Acquisition (AoA) effect. However, there is an aspect of AoA that requires research of a greater depth, namely the method of obtaining the AoA measures. In the majority of studies, adult participants were asked to estimate the age at which they learnt a given word. Morrison, Chappell, and Ellis (1997) proposed a new method for obtaining objective-AoA data. They asked children to name some objects, and the age at which a given word appeared with 75% or more frequency was considered the AoA of that word. Although this method is more valid than adult ratings, it has only rarely been used. The main aim of this work is to provide objective-AoA norms in Spanish for a set of 175 object names following the procedures used by Morrison et al. The relationships among objective-AoA, estimated-AoA, and other psycholinguistic variables (name-agreement, familiarity, visual complexity, word length, etc.) obtained from a previous study are also analysed. Finally, the similarity of objective- and estimated-AoA measures was examined using data from several languages. A cluster analysis and a multidimensional-scaling analysis revealed that the estimated-AoA measures in a language correlated more with the estimated-AoA measures of the other languages than with the objective measures in the same language. The results suggest that it would be desirable to always use objective-AoA norms because they are less skewed by familiarity.     

Psychopathy and verbal emotion processing in non-incarcerated males

Incarcerated males who score high on personality measures of psychopathy are reported to be less efficient than other incarcerated males in processing emotionally laden stimuli. In this study, we evaluated whether an emotion deficit is also present in non-incarcerated higher functioning males who score high on psychopathy personality measures. A sample of male university students was screened for psychopathic personality, and two subsamples, those who scored high or low on global psychopathy, participated in a series of language processing tasks designed to assess verbal emotion processing. Unlike previous studies of emotion processing in the verbal domain, stimuli also systematically varied in abstractness. The results showed that participants scoring high in psychopathy were less efficient than those scoring low in psychopathy in processing negatively valenced words, across all levels of word abstractness. The results extend previous accounts of emotional processing deficits in individuals with psychopathic personality to a relatively high-functioning non-incarcerated sample.     

Role of study strategy in recall of mixed lists of common and rare words

Experiment 1 confirmed previous findings that common words are more recallable than are rare words when the 2 kinds of words are presented in separate lists but not when they are presented in the same list. Experiment 2 showed much the same pattern when an orienting task was performed during word presentation. In Experiment 3 common words were found to be more recallable than rare words even for mixed lists when no warning was given of the memory test, although the effect was less pronounced than for pure lists. In Experiment 4 stronger measures were taken to preclude anticipation of the memory test, and the effect of word commonness was found to be just as pronounced with mixed lists as it was with pure lists. It was suggested that lists are studied in a way believed to optimize recall and that mixed lists foster a strategy of favoring the rare words.     

Factors influencing word naming in younger and older adults

The present study examined age differences in the influence of 3 factors that previous research has shown to influence word-naming performance. The influence of word frequency, orthographic length, and orthographic neighborhood measures was examined using large-scale regression analyses on the naming latencies for 2,820 words. Thirty-one younger adults and 29 older adults named all of these words, and age differences in the influence of these factors were examined. The results revealed that all 3 factors predicted reliable amounts of variance in word-naming latencies for both groups. However, older adults showed a larger influence of word frequency and reduced influences of orthographic length and orthographic neighborhood density compared with younger adults. Overall, these results suggest that lexical level factors increase in influence in older adults whereas sublexical factors decrease in influence.     

Perception of threat cues in post-traumatic stress disorder: Semantic processing without awareness?

Research suggests that anxiety-disordered patients semantically process, without awareness, threat cues occurring in unattended prose passages during dichotic listening (Mathews, 1984). In the present study, we attempted to demonstrate unaware semantic processing of threat cues in Vietnam combat veterans with post-traumatic stress disorder (PTSD). Control Ss included alcoholic and normal veterans, all without combat experience. To provide a rigorous test of the hypothesis, we employed a dichotic listening procedure that strictly controlled the S's attentional resources and prevented momentary attention shifts from producing results spuriously suggesting semantic processing without awareness. The processing measures included skin conductance responses and shadowing errors following presentation of threat words related to Vietnam, phonetically similar words, words threatening for other anxiety-disorder groups and neutral words. The results were inconsistent with the semantic processing without awareness hypothesis, suggesting that previous data adduced as evidence for the phenomenon may have stemmed from prose shadowing procedures that permitted momentary awareness of threat cues on the unattended channel.     

Reducing prejudice through priming of control-related words

We investigated the effect of incidentally presented constructs that imply self-control on activated stereotypes associated with immigrants. To activate immigrant stereotypes, participants responded to a scale that measures people's prejudice toward immigrants. They were then primed, using scrambled sentences, with words that were related to self-control (e.g., control, restrain, self-regulate) or with neutral words. After the priming task, participants evaluated an ambiguous behavior of a target person. On the basis of three experiments, the results showed that participants primed with the control-related words rated the target behavior more positively than those primed with neutral words. The results are discussed in relation to previous research on self-control, automatic influence of activated constructs, and prejudice reduction.     

Word Length and Vowel Duration in Apraxia of Speech: The Use of Relative Measures

Previous research has established that the duration of stressed word stem vowels is shorter in polysyllabic words than in monosyllabic words for normal speakers and for speakers with aphasia and apraxia of speech (AOS). However, the results are inconsistent across studies with regard to the magnitude and pattern of the duration reduction for apraxic speakers. We hypothesized that this inconsistency may be explained based on different relative measures of duration reduction. A speech sample was obtained from 10 aphasic speakers with AOS, 10 aphasic speakers without AOS, and 10 normal controls. As predicted, the use of two different relative measures resulted in different vowel reduction patterns, both of which were consistent with previous reports. The results further indicate that the production of polysyllabic words is particularly taxing in AOS and is associated with a substantial reduction of speaking rate compared to other aphasic and normal speakers.     

Psycholinguistic measures for German verb pairs: Semantic transparency,semantic relatedness,verb family size,and age of reading acquisition

A central issue in visual and spoken word recognition is the lexical representation of complex words—in particular, whether the lexical representation of complex words depends on semantic transparency: Is a complex verb like understand lexically represented as a whole word or via its base stand, given that its meaning is not transparent from the meanings of its parts? To study this issue, a number of stimulus characteristics are of interest that are not yet available in public databases of German. This article provides semantic association ratings, lexical paraphrases, and vector-based similarity measures for German verbs, measuring (a) the semantic transparency between 1,259 complex verbs and their bases, (b) the semantic relatedness between 1,109 verb pairs with 432 different bases, and (c) the vector-based similarity measures of 846 verb pairs. Additionally, we include the verb regularity of all verbs and two counts of verb family size for 184 base verbs, as well as estimates of age of acquisition and age of reading for 200 verbs. Together with lemma and type frequencies from public lexical databases, all measures can be downloaded along with this article. Statistical analyses indicate that verb family size, morphological complexity, frequency, and verb regularity affect the semantic transparency and relatedness ratings as well as the age of acquisition estimates, indicating that these are relevant variables in psycholinguistic experiments. Although lexical paraphrases, vector-based similarity measures, and semantic association ratings may deliver complementary information, the interrater reliability of the semantic association ratings for each verb pair provides valuable information when selecting stimuli for psycholinguistic experiments.     

Norms of valence,arousal, concreteness,familiarity, imageability,and context availability for 1,100 Chinese words

In the present study, we collected valence, arousal, concreteness, familiarity, imageability, and context availability ratings for a total of 1,100 Chinese words. The ratings for all variables were collected with 9-point Likert scales. We tested the reliability of the present database by comparing it to the extant Chinese Affective Word System, and performed split-half correlations for all six variables. We then evaluated the relationships between all variables. Regarding the affective variables, we found a typical quadratic relation between valence and arousal, in line with previous findings. Likewise, significant correlations were found between the semantic variables. Importantly, we explored the relationships between ratings for the affective variables (i.e., valence and arousal) and concreteness ratings, suggesting that valence and arousal ratings can predict concreteness ratings. This database of affective norms will be a valuable source of information for emotion research that makes use of Chinese words, and will enable researchers to use highly controlled Chinese verbal stimuli to more reliably investigate the relation between cognition and emotion.     

Influence of parafoveal processing on the missing-letter effect

According to the parafoveal-processing hypothesis, letters are more often missed in function words than in content words because the former are more likely to be identified in the parafovea, where letter processing is not available. Contrary to previous demonstrations, more omissions occurred in function words than in content words when parafoveal processing was not available because words were displayed in column format, text was read through a 5-letter window, or words were presented 1 at a time on a computer screen. In all experiments, impeding parafoveal processing decreased omission rates for function but not for content words. In the last experiment, direct monitoring of eye movements revealed that, for both fixated and skipped words, letters in function words are missed more often than content words. These results are best interpreted within a model including the structural precedence hypothesis and stressing the importance of visual factors.     

Cognitive bias,emotion, and somatic complaints in a normal sample

Cognitive bias (Stroop interference and implicit memory bias) for masked and unmasked threat words (illness words and negative emotion words) was investigated for its associations with emotion (anxiety, anger/aggression, and positive affect) and somatic complaints in a randomly selected community sample of 138 individuals. Because measures of cognitive bias are inherently bipolar, the data were tested for both linear and curvilinear trends. Cross-sectional analysis showed that the associations between somatic anxiety and Stroop interference for unmasked threat words were better described in terms of curvilinear than linear models, and that degree of somatic complaints was associated with Stroop facilitation for masked threat words. Longitudinal analysis showed that Stroop interference for masked threat words predicted lack of positive affect during an ensuing eight weeks daily recording period. Implicit memory bias was found to be negatively associated with measures of anger/aggression, both in the cross-sectional and longitudinal analyses. We suggest that: (a) cognitive bias should be treated as a bipolar construct in future research; (b) the phenomenon of Stroop facilitation for threat words deserves further exploration; and (c) more research should address the question about the relationship between cognitive bias and other emotions than anxiety (e.g., positive affect and anger).     

A web-based interface to calculate phonotactic probability for words and nonwords in English.

Phonotactic probability refers to the frequency with which phonological segments and sequences of phonological segments occur in words in a given language. We describe one method of estimating phonotactic probabilities based on words in American English. These estimates of phonotactic probability have been used in a number of previous studies and are now being made available to other researchers via a Web-based interface. Instructions for using the interface, as well as details regarding how the measures were derived, are provided in the present article. The Phonotactic Probability Calculator can be accessed at http://www.people.ku.edu/-mvitevit/PhonoProbHome.html.     

Associative processes in repetition priming

Three experiments that investigated alternative accounts of repetition priming are reported. All 3 experiments used semantic comparison tasks and included trials in which each of the 2 words being compared had previously occurred on separate trials. In the re-pair match condition, the response required matched that on the 2 previous trials in which the words had occured. In there-pair mismatch condition, the response required was opposite to that on the previous trials containing the words forming the critical pair. In all 3 experiments, responses were faster and more accurate in the re-pair match condition than in the re-pair mismatch condition. Possible accounts of this effect within the frameworks of instance theory and of transfer appropriate processing are considered.
