Citation rates for experimental psychology articles published between 1950 and 2004: Top-cited articles in behavioral cognitive psychology

From citation rates for over 85,000 articles published between 1950 and 2004 in 56 psychology journals, we identified a total of 500 behavioral cognitive psychology articles that ranked in the top 0.6?% in each half-decade, in terms of their mean citations per year using the Web of Science. Thirty nine of these articles were produced by 78 authors who authored three or more of them, and more than half were published by only five journals. The mean number of cites per year and the total number of citations necessary for an article to achieve various percentile rankings are reported for each journal. The mean number of citations necessary for an article published within each half-decade to rank at any given percentile has steadily increased from 1950 to 2004. Of the articles that we surveyed, 11?% had zero total citations, and 35?% received fewer than four total citations. Citations for post-1994 articles ranking in the 50th-75th and 90th-95th percentiles have generally continued to grow across each of their 3-year postpublication bins. For pre-1995 articles ranking in the 50th-75th and 90th-95th percentiles, citations peaked in the 4- to 6- or 7- to 9-year postpublication bins and decreased linearly thereafter, until asymptoting. In contrast, for the top-500 articles, (a) for pre-1980 articles, citations grew and peaked 10-18-year postpublication bins, and after a slight decrease began to linearly increase again; (b) for post-1979 articles, citations have continually increased across years in a nearly linear fashion. We also report changes in topics covered by the top-cited articles over the decades.     

The Speech Anxiety Thoughts Inventory: scale development and preliminary psychometric data

Cognitions have been known to play a central role in the development, maintenance, and treatment of speech anxiety. However, few instruments are currently available to assess cognitive contents associated with speech anxiety. This report describes three studies examining the psychometric characteristics of a revised English version of the Speech Anxiety Thoughts Inventory (SATI)-an instrument measuring maladaptive cognitions associated with speech anxiety. In Study 1, factor analyses of the SATI revealed a two-factor solution-"prediction of poor performance" and "fear of negative evaluation by audience", respectively. In Study 2, the two-factor structure was replicated. In addition, results revealed stability over a four-week period, high internal consistency, and good convergent and discriminant validity. In Study 3, the scale demonstrated sensitivity to change following brief exposure-based treatments. These findings suggest that the SATI is a highly reliable, valid measure to assess cognitive features of speech anxiety.     

Polarity correspondence: A general principle for performance of speeded binary classification tasks

Differences in performance with various stimulus-response mappings are among the most prevalent findings for binary choice reaction tasks. The authors show that perceptual or conceptual similarity is not necessary to obtain mapping effects; a type of structural similarity is sufficient. Specifically, stimulus and response alternatives are coded as positive and negative polarity along several dimensions, and polarity correspondence is sufficient to produce mapping effects. The authors make the case for this polarity correspondence principle using the literature on word-picture verification and then provide evidence that polarity correspondence is a determinant of mapping effects in orthogonal stimulus-response compatibility, numerical judgment, and implicit association tasks. The authors conclude by discussing implications of this principle for interpretation of results from binary choice tasks and future model development.     

Perceptual Recovery from Consonant-Cluster Simplification in Korean Using Language-Specific Phonological Knowledge

Two experiments examined whether perceptual recovery from Korean consonant-cluster simplification is based on language-specific phonological knowledge. In tri-consonantal C1C2C3 sequences such as /lkt/ and /lpt/ in Seoul Korean, either C1 or C2 can be completely deleted. Seoul Koreans monitored for C2 targets (/p/ or / k/, deleted or preserved) in the second word of a two-word phrase with an underlying /l/-C2-/t/ sequence. In Experiment 1 the target-bearing words had contextual lexical-semantic support. Listeners recovered deleted targets as fast and as accurately as preserved targets with both Word and Intonational Phrase (IP) boundaries between the two words. In Experiment 2, contexts were low-pass filtered. Listeners were still able to recover deleted targets as well as preserved targets in IP-boundary contexts, but better with physically-present targets than with deleted targets in Word-boundary contexts. This suggests that the benefit of having target acoustic-phonetic information emerges only when higher-order (contextual and phrase-boundary) information is not available. The strikingly efficient recovery of deleted phonemes with neither acoustic-phonetic cues nor contextual support demonstrates that language-specific phonological knowledge, rather than language-universal perceptual processes which rely on fine-grained phonetic details, is employed when the listener perceives the results of a continuous-speech process in which reduction is phonetically complete.     

Obesity-Related Quality of Life and Distorted Self-Body Image in Adults

Quality of life (QOL) is associated with body mass index (BMI). Self-awareness of false body image may influence the behavior of weight control and QOL. This study was conducted to identify the relationships between BMI and QOL, and distortion of self-estimated body image and its impact on QOL and the general health of Korean adults. A total of 229 adults who visited two university hospitals in Seoul and Chungju cities for regular health check-up responded to a questionnaire. To assess QOL, a Korean version of the obesity-related Quality of Life Scale (KOQOL) was used. The results showed that obesity-related quality of life decreased as BMI increased and as alcohol consumption became heavier. In the low weight and normal body weight groups, a portion of the groups had a more obese self-estimated body image than their actual BMI. In the overweight and obese groups, some had a leaner self-estimated body image than their actual BMI. Persons who had a self-body image of being fat had a low QOL. For Korean adults over 20 and under 65, a higher BMI is associated with a lower obesity-related quality of life. Persons who thought themselves fat had a lower QOL, regardless of their real body type.     

Competent Adolescent Readers’ Use of Internet Reading Strategies: A Think-Aloud Study

The purpose of this study was to investigate the type, pattern, and complexity of Internet reading strategies used by seven accomplished high school readers. Individual participants performed an academic Internet reading task with the goal of developing critical questions about their chosen controversial topic. Strategies for Internet reading were analyzed from the perspective of constructively responsive reading, both qualitatively and quantitatively, using participant-generated verbal reports complemented by recordings of their computer screens. The data described the nature and sequence of reading strategies that participants used to construct meaning, and the interplay of those multiple strategies in Internet settings. The results demonstrated that the participants’ Internet reading involved the iteration and modification of traditional print-based reading strategies (e.g., meaning-making, self-monitoring, information evaluation) and also the use of strategies characteristic of Internet settings (e.g., text location). Implications of the study's findings on Internet reading strategy use for theory and research are discussed.     

Impaired color word processing at an unattended location: Evidence from a Stroop task combined with inhibition of return

A Stroop task with separate color bar and color word stimuli was combined with an inhibition-of-return procedure to examine whether visual attention modulates color word processing. In Experiment 1, the color bar was presented at the cued location and the color word at the uncued location, or vice versa, with a 100- or 1,050-msec stimulus onset asynchrony (SOA) between cue and Stroop stimuli. In Experiment 2, on Stroop trials, the color bar was presented at a central fixated location and the color word at a cued or uncued location above or below the color bar. In both experiments, with a 100-msec SOA, the Stroop effect was numerically larger when the color word was displayed at the cued location than when it was displayed at the uncued location, but with the 1,050-msec SOA, this relation between Stroop effect magnitude and location was reversed. These results provide evidence that processing of the color word in the Stroop task is modulated by the location to which visual attention is directed.
