Semantic determinants of pauses

Summary The following experiment presents evidence that variations in semantic context can produce changes in the rate and length of pauses in a situation in which syntactic and other variations are minimized. Each of 40 Ss read two paragraphs aloud and after each paragraph retold the story without further instructions. Each paragraph consisted of five sentences, each containing 23 syllables. The third sentence was either in accord with the story or an unusual occurrence (depending on exchange of subject and object). The most important experimental finding was that both number and length of unfilled pauses are more frequent throughout the unusual stories as compared with the usual ones. In the readings, the effect was limited to the critical sentence and the pauses immediately thereafter. The evidence supports the view of the authors that the role of semantic context has been underestimated in psycholiguistic research to date.

Zusammenfassung Das folgende Experiment weist darauf hin, daß Variationen des semantischen Kontextes zu Veränderungen in der Anzahl und Länge von Pausen führen können, auch wenn syntaktische und andere Variationen kontrolliert werden. 40 Vpn lasen zwei Abschnitte laut vor und erzählten die Geschichte nach jedem Abschnitt ohne weitere Instruktion. Jeder Abschnitt bestand aus fünf Sätzen, jeder Satz enthielt 23 Silben. Der dritte Satz stimmte mit dem sonstigen Inhalt der Geschichte überein oder wich davon ab (durch Austausch von Subjekt und Objekt). Als wichtigster experimenteller Befund stellte sich heraus, daß bei den ungewöhnlichen Geschichten die Anzahl und Länge der ungefüllten Pausen größer waren als bei den normalen Geschichten. Bei den Lesungen trat dieser Effekt nur innerhalb des kritischen Satzes und unmittelbar danach auf. Die Ergebnisse unterstützen die Meinung der Autoren, daß die Rolle des semantischen Kontextes in der psycholinguistischen Forschung bisher vernachlässigt wurde.

Object identification: The mental representation of physical and conceptual attributes

In two experiments, subjects indicated whether two pictures of familiar objects were equivalent. The picture pairs were identical, showed the same object in various perspectives and states, or showed different objects with varying degrees of conceptual relatedness. In Experiment 1, the equivalence criterion for judging the picture pairs was varied between subjects (identity of pictures; conceptual equivalence of objects at subordinate, basic, or superordinate level). The reaction times of the four subject groups suggest that a pictorial stimulus is not always mentally represented in the same way, and that the instructions given determine which attributes of the stimulus are represented. In Experiment 2, the visual similarity of the picture pairs was varied. The results indicate, at least with a basic-level equivalence instruction, that not only perceptual, but also non-perceptual, functional attributes are represented—namely, those that, according to Rosch et al. (1976), are common to the members of a superordinate category.     

Lexically restricted utterances in Russian, german, and english child-directed speech

This study investigates the child-directed speech (CDS) of four Russian-, six German, and six English-speaking mothers to their 2-year-old children. Typologically Russian has considerably less restricted word order than either German or English, with German showing more word-order variants than English. This could lead to the prediction that the lexical restrictiveness previously found in the initial strings of English CDS by Cameron-Faulkner, Lieven, and Tomasello (2003 ) would not be found in Russian or German CDS. However, despite differences between the three corpora that clearly derive from typological differences between the languages, the most significant finding of this study is a high degree of lexical restrictiveness at the beginnings of CDS utterances in all three languages.     

Comparison of ability tests administered online and in the laboratory

As the Internet, the global medium of the future, expands exponentially, it has become increasingly relevant to scientific research. So far, there is but little evidence that online testing is suitable for collecting ability-test data. The present article aims to shed light on some aspects of the issue by comparing the performance in a computer-administered ability test of one lab sample and two online samples using a quasi-experimental design. Mean score differences appeared, but can be explained by differences in age and education, and were not due to the test setting (online vs. laboratory). Also, there were no structural differences between the achievement scores of both samples. Some limitations on generalizability are discussed.     

Eighteen‐month‐old infants show distinct electrophysiological responses to their own faces

Infants attain the developmental milestone of self‐recognition around 18 to 24 months of age. At 18 months of age, half of the infant population typically shows signs of self‐recognition in the classic mirror test. The current study examined the functional neural correlates of the perception of self in infancy. Eighteen‐month‐old infants observed photographs of their own face, the face of an unfamiliar infant, the face of their caregiver, and the face of an unfamiliar caregiver, while their EEG was registered. The results show that infants show an enhanced response to their own face compared to other faces. The N290, an established face‐selective ERP component in infants, was larger for observation of their own face compared to others’ faces. In addition to the EEG task, the mirror test was administered. Half of the infants in our sample recognized themselves in the mirror. However, there were no differences in the ERP responses between the infants who did and did not recognize themselves in the mirror. This suggests that a distinction between the neural response to self and to others does not necessarily express itself in self‐recognition behavior.     

Approach-avoidance goals and relationship problems,communication of stress,and dyadic coping in couples

Partners in romantic relationships differ in the extent to which they are oriented towards positive outcomes (e.g., intimacy) or away from negative outcomes (e.g., conflict). The present study examines these approach-avoidance relationship goals in relation to self-reported relationship problems, stress communication, and dyadic coping. Hypotheses were tested on a dyadic level (Actor-Partner Interdependence Model) using data from 368 couples. As expected, people endorsing approach goals reported fewer relationship problems, more effective stress communication, and better dyadic coping. People endorsing avoidance goals reported more relationship problems and poorer dyadic coping. Further, approach-oriented people tended to perceive their partner as being more communicative and more supportive, whereas avoidance-oriented people tended to perceive their partner as more communicative but less supportive. Reports by partners agreed with the self-reports of approach- and avoidance-oriented spouses concerning stress communication and dyadic coping. These findings highlight motivational factors in general, and orientation towards approach-avoidance goals in particular, as key features in understanding relationship maintenance.     

The ethnic match between students and teachers: evidence from a vignette study

The ethnic match between teachers and students is widely believed to be beneficial for the achievement of ethnic minority students, who often lag behind their ethnic majority peers. In a quasi-experimental vignette study, we investigated whether preservice teachers who shared the same ethnic background as the student in the vignette had different judgments of the achievement, working and learning habits, and other social variables of the target student than ethnic majority preservice teachers and preservice teachers who had an ethnic minority background different from that of the student. Additionally, we asked about the causes of ethnic disparities. The preservice teachers who shared the same ethnic background as the target student more favorably judged the student’s language proficiency in his mother tongue and perceived the student as more proficient in mathematics, science, and general competence than the two other teacher groups. Moreover, the causal attributions showed that the preservice teachers with the same background as the target student generally perceived the causes of the student’s lower school success as multifaceted. The results reveal that simply having a teacher with an ethnic minority background is not sufficient for benefitting ethnic minority students. Only teachers who have the same ethnic background as the students might contribute to the reduction of ethnic disparities in school.     

Group evaluations as self-group distancing: Ingroup typicality moderates evaluative intergroup bias in stigmatized groups

Outgroup favoritism among members of stigmatized groups can be seen as a form of self-group distancing. We examined how intergroup evaluations in stigmatized groups vary as a function of ingroup typicality. In Studies 1 and 2, Black participants (N = 125,915; N = 766) more strongly preferred light-skinned or White relative to dark-skinned or Black individuals the lighter their own skin tone. In Study 3, overweight participants (N = 147,540) more strongly preferred normal-weight relative to overweight individuals the lower their own body weight. In Study 4, participants with disabilities (N = 35,058) more strongly preferred non-disabled relative to disabled individuals the less visible they judged their own disability. Relationships between ingroup typicality and intergroup evaluations were at least partially mediated by ingroup identification (Studies 2 and 3). A meta-analysis across studies yielded an average effect size of r = .12. Furthermore, higher ingroup typicality was related to both ingroup and outgroup evaluations. We discuss ingroup typicality as an individual constraint to self-group distancing among stigmatized group members and its relation to intergroup evaluations.     

General mood of professional caregivers in child care centers and the quality of caregiver–child interactions

The present study is the first to relate professional caregivers’ general mood to the observed quality of their interactions with the children in their care. A total of 238 female caregivers from 133 child care groups in 64 centers completed the General mood scale of Bar-On’s Emotional Quotient Inventory (1997) and was observed while playing with small groups of children. Factor analysis on the General mood scale yielded five general mood factors, one negative and four positive. Two positive mood factors in particular, i.e., positivity and optimism, were found to contribute positively to the quality of professional caregivers’ behavior toward the children and, through their caregiving behavior, to the children’s well-being.
