Phonemic priming with words and pseudowords

Abstract

The bi-alphabetic nature of the Serbo-Croatian writing system allows unequivocal examination of phonemic similarity unconfounded with graphemic similarity. The Roman and Cyrillic alphabets are largely independent but map onto the same sounds. A lower-case context written in one alphabet bears no visual similarity to an uppercase target written in the other alphabet. One naming experiment and one lexical decision experiment investigated phonemic priming of high-frequency words and pseudowords with word and pseudoword contexts. For naming, targets that were phone-mically similar to the preceding context were named significantly faster than were phonemically dissimilar targets. This result was indifferent to the lexicality of the contexts and targets. For lexical decision, in contrast, phonemically similar word-word pairs showed inhibition, whereas phonemically similar pseudoword-word pairs showed facilitation relative to their phonemically dissimilar counterparts. These results were discussed in terms of (1) a model of visual word processing that posits a layer of phoneme units between letter units and word units, and (2) the idea that active word units inhibit one another in proportion to each one's frequency. In this account, phonemic similarity effects in naming are based on the states of the phoneme units, while phonemic similarity effects in lexical decision are based on the states of the word units. These results lend further support to the claim that, for readers of Serbo-Croatian, the visual computation of phonology is automatic and prelexical.     

Messages about sex in the workplace: A content analysis of primetime television

Because television has the potential to shape cultural beliefs about both sexual norms and appropriate workplace behavior, it seems important to examine TV’s portrayal of “sexual etiquette” in the workplace. In a content analysis of two episodes of every primetime comedy aired on all broadcast and cable networks during fall 2000, we coded every sexual remark and behavior made in a workplace scene. Across all networks, 85 percent of programs and one in four workplace interactions contained some type of sexual content. Overall, a viewer is likely to hear eleven sexual remarks and see two to three sexual behaviors in a workplace setting per hour; this jumps to twenty-three remarks and nine behaviors on cable networks. Sexual remarks were mostly explicit, made in an office setting, by White men, and were rarely (1.4%) about sexual harassment or discrimination. Although sexual content in the workplace was generally less common on broadcast than cable networks, a broadcast network (Fox) actually had the highest overall rate, with sexual content in 38 percent of workplace scenes. Given that research suggests that TV teaches youth about sexuality and cultivates sexual attitudes and beliefs consistent with televised portrayals, it is alarming that youth may learn from television that sex in the workplace is not only commonplace, but also to be tolerated and enjoyed.     

Personality Disorders and Spinal Cord Injury: A Pilot Study

A substantial body of research has found that spinal cord injury (SCI) patients have relatively high degrees of energy, impulsivity, and risk-taking (W. Fordyce, 1964; G. P. Taylor, 1970; B. Woodbury, 1978). The present study endeavors to extend our knowledge to the personality disorder (PD) domain. Forty SCI participants and 40 matched controls were given a semistructured diagnostic interview and a self-report personality disorder instrument. Findings indicated that 27.5% of SCI patients, and a similar number of controls, have PDs. Unexpectedly, impulsive/externalizing disorders (histrionic, narcissistic, antisocial, and borderline) were not unusually high in SCI patients, and were not higher than controls. Avoidant and depressive disorders were unexpectedly high.     

The Structure and Dynamics of Worry: Theory, Measurement, and Cross-National Replications

This article presents a comprehensive conceptualization of the structure of worry and the relation of worry to mental health and well-being. It is assumed that worries have two facets, namely, the object of a worry (e.g., self, close others, society, the world) and the domain of a worry (the field of life with which it is concerned). The object of a worry is presumed to be more important than its domain in determining the impact of worries on mental health. Only worries concerned with self and close others (micro worries) are expected to be related to poor mental health, whereas worries about society or the entire world (macro worries) are expected to be positively related to mental health. An instrument is introduced to study worries in accordance with the proposed structure. Its validity is tested by two confirmatory techniques (similarity structure analysis and confirmatory factor analysis) in samples from Israel, West Germany, and (the former) East Germany. Worry scores are also related to five mental health indicators. Results show that across samples micro and macro worries can validly be distinguished. Micro worries are strongly related to poor mental health, whereas macro worries are unrelated to mental health or relate marginally to positive well-being.     

Prehension movements and perceived object depth structure

This study asked the question, “Will the motor pattern to a perceived two-dimensional (2-D) object differ from that same object when it is perceived as three dimensional (3-D)?” Subjects were required to reach and grasp an apple that could appear to be 2-D or 3-D. Two experimental sessions were conducted. In Condition A, the apple was initially perceived to be 2-D, but, for 20% of trials, it suddenly shifted to a 3-D apple at movement onset. In Condition B, the apple was initially perceived to be 3-D, but, for 20% of trials, it suddenly shifted to a 2-D silhouette of the same apple. For control trials, subjects grasped the perceived 2-D apple as if it were a disc (82%), and they grasped the 3-D apple, as they would a normal apple, with a whole-hand grasp (86%). For Condition A perturbed trials, there was a rapid change from a 2-D precision grip to a 3-D whole-hand prehension, whereas the converse was true for the opposite perturbation. Peak acceleration was anticipated for Condition A perturbed trials but not for Condition B perturbed trials. These results indicate that the motor patterns we use in interacting with an object are strongly influenced by the way we perceive the object in real time, and that object affordances, such as dimension, can override the influence exerted by existing representations.     

Cognitive costs of encoding novel natural activities: Can “learning by doing” be distracting and deceptive?

Findings from action memory research suggest that the enactment of simple actions and naturalistic activities results in similar memory performance to that from their observation. However, little is known about potential differences between the conditions during the encoding of the to-be-studied actions and activities. We analysed the cognitive costs of encoding two novel naturalistic activities studied via enactment or via observation in four experiments. In addition to memory performance, we measured objective cognitive costs with a secondary task and subjective cognitive costs with repeated ratings of mental effort and estimates of general activity difficulty. Memory performance was comparable across study conditions throughout all experiments. The enactment of activities repeatedly resulted in slower reaction times in the secondary task than did observation, suggesting higher objective costs. In contrast, subjective costs were rated lower after enactment than after observation. Findings from a pantomimic enactment condition suggested that the low ratings of subjective costs after enactment represent a misinterpretation of task demands. Our findings imply that the widespread belief about “learning by doing” as an easy way of learning does not stem from an actual advantage in memory performance, but rather from continuous feedback about one's performance resulting from enactment.     

Verbal facilitation effects instead of verbal overshadowing in face memory of 4- to 6-year olds

Research on eye witness memory in older children and adults revealed that verbally describing unfamiliar faces impairs later recognition of these faces, known as the “verbal overshadowing effect”. The aim of this study was to investigate whether a verbal overshadowing effect occurs in 4- to 6-year olds, too, and whether visualization (i.e., drawing the seen face) might elicit a visual overshadowing effect. Instead of a verbal overshadowing effect, a verbal facilitation effect was revealed with verbal intelligence being a significant predictor for recognition accuracy in the verbalization group but not in the control group. No effect of visualization was observed on recognition accuracy. Potential explanations for the results are discussed.
