Communicating emotion: linking affective prosody and word meaning

The present study investigated the role of emotional tone of voice in the perception of spoken words. Listeners were presented with words that had either a happy, sad, or neutral meaning. Each word was spoken in a tone of voice (happy, sad, or neutral) that was congruent, incongruent, or neutral with respect to affective meaning, and naming latencies were collected. Across experiments, tone of voice was either blocked or mixed with respect to emotional meaning. The results suggest that emotional tone of voice facilitated linguistic processing of emotional words in an emotion-congruent fashion. These findings suggest that information about emotional tone is used in the processing of linguistic content influencing the recognition and naming of spoken words in an emotion-congruent manner.     

ListChecker Pro 1.2: A program designed to facilitate creating word lists using the University of South Florida word association norms

Various areas of research (e.g., memory, metamemory, visual word recognition, associative priming) rely on the careful construction of reliable word lists. ListChecker Pro 1.2 is a computer program that accesses the University of South Florida word association norms (Nelson, McEvoy, & Schreiber, 1998, 2004) to report characteristics of words (e.g., frequency, concreteness), as well as direct and indirect associative relationships (e.g., shared associates, mediators). The present article presents the input requirements, menu options, and output obtained by ListChecker Pro 1.2. In addition, a randomly selected list of words from the associative versus semantic priming literature was submitted to ListChecker Pro 1.2 to demonstrate how seemingly unrelated words can be associated.

Corpus-based estimates of word association predict biases in judgment of word co-occurrence likelihood

This paper draws a connection between statistical word association measures used in linguistics and confirmation measures from epistemology. Having theoretically established the connection, we replicate, in the new context of the judgments of word co-occurrence, an intriguing finding from the psychology of reasoning, namely that confirmation values affect intuitions about likelihood. We show that the effect, despite being based in this case on very subtle statistical insights about thousands of words, is stable across three different experimental settings. Our theoretical and empirical results suggest that factors affecting traditional reasoning tasks are also at play when linguistic knowledge is probed, and they provide further evidence for the importance of confirmation in a new domain.     

Semantic context effects and priming in word association

Two experiments investigated priming in word association, an implicit memory task. In the study phase of Experiment 1, semantically ambiguous target words were presented in sentences that biased their interpretation. The appropriate interpretation of the target was either congruent or incongruent with the cue presented in a subsequent word association task. Priming (i.e., a higher proportion of target responses relative to a nonstudied baseline) was obtained for the congruent condition, but not for the incongruent condition. In Experiment 2, study sentences emphasized particular meaning aspects of nonambiguous targets. The word association task showed a higher proportion of target responses for targets studied in the more congruent sentence context than for targets studied in the less congruent sentence context. These results indicate that priming in word association depends largely on the storage of information relating the cue and target.     

Acquired affective associations induce emotion effects in word recognition: An ERP study

The present study examined how contextual learning and in particular emotionality conditioning impacts the neural processing of words, as possible key factors for the acquisition of words’ emotional connotation. 21 participants learned on five consecutive days associations between meaningless pseudowords and unpleasant or neutral pictures using an evaluative conditioning paradigm. Subsequently, event-related potentials were recorded while participants implicitly processed the learned emotional relevance in a lexical decision paradigm. Emotional and neutral words were presented together with the conditioned pseudowords and a set of new pseudowords. Conditioned and new pseudowords differed in the late positive complex. Emotionally and neutrally conditioned stimuli differed in an early time window (80–120 ms) and in the P300. These results replicate ERP effects known from emotion word recognition and indicate that contextual learning and in particular evaluative conditioning is suitable to establish emotional associations in words, and to explain early ERP effects in emotion word recognition.     

Normative data for number of word meanings

A corpus of 576 words and orthographically legal pseudowords was rated by 150 undergraduates to obtain a subjective estimate of the number of meanings possessed by the stimuli. The information contained in this corpus may be used to supplement current, sources of word-meaning information (e.g., total number of dictionary entries). Experimental evidence is presented that supports the reliability of the normative data.     

Estimating the effect of word predictability on eye movements in Chinese reading using latent semantic analysis and transitional probability

Latent semantic analysis (LSA) and transitional probability (TP), two computational methods used to reflect lexical semantic representation from large text corpora, were employed to examine the effects of word predictability on Chinese reading. Participants' eye movements were monitored, and the influence of word complexity (number of strokes), word frequency, and word predictability on different eye movement measures (first-fixation duration, gaze duration, and total time) were examined. We found influences of TP on first-fixation duration and gaze duration and of LSA on total time. The results suggest that TP reflects an early stage of lexical processing while LSA reflects a later stage.     

Estimating the reliability of interview data

A model for a score based on an interview is presented which identifies the effect due to the subject, to the manner in which the interviewer tends to conduct his interviews, to the criteria he tends to use in scoring subjects' responses, to the compromises he tends to adopt between the demands of interviewing and those of scoring, and to chance errors. A suggested experimental design calls for each ofK investigators to interview a different sample ofN subjects, but for all investigators to score each subject. The drawing of inferences when interest is only in theK participants in the reliability study is considered, and a numerical example is given.This work was supported in part by grant DE R01 00793 from the National Institute of Dental Research, and in part by grants MH 08534 and MH 09191 from the National Institute of Mental Health, and forms part of the author's Ph.D. dissertation at Columbia University.
