Attentional and perceptual sources of the auditory attentional blink

When a rapid succession of auditory stimuli is listened to, processing of the second of two successive targets among fillers is often impaired, a phenomenon known as the attentional blink (AB). Three experiments were conducted to examine the role of filler items in modulating the size of the auditory AB, using a two-alternative forced choice discrimination paradigm. In the first experiment, dual-stream presentations in which low- and high-pitch items were separated by six semitones were tested. A transient deficit in reporting the probe was observed in the presence of fillers that was greater when fillers were in the same stream as the probe. In the absence of a filler, there was a residual deficit, but this was not related to the time lag between the target and the probe. In the second and third experiments, in which single-stream presentations were used, a typical AB was found in the presence of homogeneous fillers, but heterogeneous fillers tended to produce a greater deficit. In the absence of a filler, there was little or no evidence of a blink. The pattern of results suggests that other attentional and perceptual factors contribute to the blink.     

Social Support Mobilization and Deterioration after Mexico’s 1999 Flood: Effects of Context, Gender, and Time

Samples of adults representative of Teziutlán, Puebla, and Villahermosa, Tobasco, were interviewed 6, 12, 18, and 24 months after the devastating 1999 flood and mudslides. The interview contained multiple measures of social support that had been normed for Mexico. Comparisons between sample data and population norms suggested minimal mobilization of received support and substantial deterioration of perceived support and social embeddedness. Social support was lowest in Teziutlán, which had experienced mass casualties and displacement, and among women and persons of lower educational attainment. Disparities according to gender, context, and education grew larger as time passed. The results provide compelling evidence that the international health community must be mindful of social as well as psychological functioning when disasters strike the developing world.     

Auditory attentional capture during serial recall: violations at encoding of an algorithm-based neural model?

A novel attentional capture effect is reported in which visual-verbal serial recall was disrupted if a single deviation in the interstimulus interval occurred within otherwise regularly presented task-irrelevant spoken items. The degree of disruption was the same whether the temporal deviant was embedded in a sequence made up of a repeating item or a sequence of changing items. Moreover, the effect was evident during the presentation of the to-be-remembered sequence but not during rehearsal just prior to recall, suggesting that the encoding of sequences is particularly susceptible. The results suggest that attentional capture is due to a violation of an algorithm rather than an aggregate-based neural model and further undermine an attentional capture-based account of the classical changing-state irrelevant sound effect.     

The effect of deleting schwa (mute e) on spoken word recognition in French]

We studied the processing of two word strings in French made up of a determiner and a noun which contains a schwa (mute e). Depending on the noun, schwa deletion is present ("la tir'lire"), optional ("le ch(e)min") or absent ("la cornemuse"). In a production study, we show that schwa deletion, and the category of the noun, have a large impact on the duration of the strings. We take this into account in two perception studies, which use word repetition and lexical decision, and which show that words in which the schwa has been deleted usually take longer to recognize than words that retain the schwa, but that this depends also on the category of the word. We explain these results by examining the influence of orthography. Based on the model proposed by Grainger and Ferrand (1996), which integrates the written dimension, we suggest that two sources of information, phonological and orthographic, interact during spoken word recognition.     

Picture naming in 3- to 8-year-old French children: Methodological considerations for name agreement

Picture naming has become an important experimental paradigm in cognitive psychology. Young children are more variable than adults in their naming responses and less likely to know the object or its name. A consequence is that the interpretation of the two classical measures used by Snodgrass and Vanderwart (1980) for scoring name agreement in adults (the percentage of agreement, based on modal name, and theH statistic, based on alternative names) will differ because of the high rate of “don’t know object” responses, common in young children, relative to the low rate of “don’t know object” responses more characteristic of adults. The present study focused on this methodological issue in young French children (3–8 years old), using a set of 145 Snodgrass-Vanderwart pictures. Our results indicate that the percentage of agreement based on the expected name is a better measure of picture-naming performance than are the commonly used measures.

Comparing language and religion in normative arguments about linguistic justice

Many of the most influential theorists of linguistic justice make arguments on the basis of comparisons between language and religion. They claim either that (1) language, by contrast with religion, cannot be separated from the state or that (2) unequal official linguistic recognition, just like unequal official religious recognition, is morally problematic. This article argues that careful attention to debates about liberalism and the place of religion in public life invites us to question the two above-mentioned liberal assumptions about religion underlying many arguments concerning linguistic justice based on (dis)analogies between language and religion. The hope is that such critical scrutiny is likely to shed some light on normative questions of linguistic justice, more precisely on questions about the legitimacy of granting more recognition to certain languages, usually those of national native groups (as opposed to groups resulting from more or less recent immigration).     

Sensory effects on judgments of short time-intervals

Two experiments were conducted to test the effect of nontemporal factors on duration discrimination. In Exp. 1, a forced-choice adaptive procedure with a standard duration of 400 or 800 ms was employed. It was shown that, for both auditory and visual modes, the discrimination is better with empty intervals (a silent period between two brief signals) than with filled intervals (a continuous signal), but only with shorter durations. In a second experiment, where intervals of the same duration range were employed but were presented with a single-stimulus method, discrimination was better with empty than with filled intervals, and this effect applied to both ranges of duration and both sensory modes. In both experiments, discrimination was better in the auditory than in the visual mode. These data are discussed in the context of current models of timing mechanisms.

Cultural Dimensions,Gender, and the Nature of Self-concept: A Fourteen-country Study

Ratings of the importance of and satisfaction with 20 areas of the self were obtained from 3604 first or second year social science undergraduates from 14 countries (15 cultures). Factor analysis at the culture by gender level supported four factors for both sets of ratings. The resulting factor scores were analyzed for mean differences according to the cultural dimension of Individualism-Collectivism by Gender and by correlations with other cultural dimenions and economic indicators. It was found that participants from the 10 collectivist cultures placed greater salience for their self-concepts on “family values” than did those from the individualist cultures. However, this cultural difference was not found for “social relationships”. The expected gender differences, with females valuing “family values” and “social relationships” more highly, were found only for the individualist countries. The findings indicate that there may be a strong cultural level interaction effect between gender and Individualism-Collectivism on the nature of self-conceptions, and that the “family” and “social” aspects of self-concept in collectivist countries need to be considered separately.     

System influences on posthomicide beliefs and distress

Criminal justice system experiences in 150 family members of homicide victims were investigated. The study had two goals: (a) to document the experiences of homicide survivors in the criminal justice system, including case outcomes, criminal justice system activities, and satisfaction with system personnel; and (b) to determine if experiences with the police impacted posthomicide beliefs (cognitive assumptions about the world and one’s relationship to it) and psychological distress. The sample, which was identified through the Medical Examiner’s Office, was drawn from all criminal homicides from 1.5 to 5 years prior to selection. Results showed that family members of homicide victims were very dissatisfied with their experiences in the criminal justice system. Additionally, whereas objective system outcomes (e.g, arrest) did not directly affect posthomicide beliefs and distress, subjective system outcomes (e.g., police satisfaction) directly affected beliefs and indirectly affected distress. There was some support for both equity theory and a cognitive theory of change, the two theories that guided the model specification.
