Cultures of moderation and expression: emotional experience, behavior, and physiology in Chinese Americans and Mexican Americans

Ethnographic accounts suggest that emotions are moderated in Chinese cultures and expressed openly in Mexican cultures. The authors tested this notion by comparing subjective, behavioral, and physiological aspects of emotional responses to 3 (warned, unwarned, instructed to inhibit responding) aversive acoustic startle stimuli in 95 Chinese Americans and 64 Mexican Americans. Subjective reports were consistent with ethnographic accounts; Chinese Americans reported experiencing significantly less emotion than Mexican Americans across all 3 startle conditions. Evidence from a nonemotional task suggested that these differences were not artifacts of cultural differences in the use of rating scales. Few cultural differences were found in emotional behavior or physiology, suggesting that these aspects of emotion are less susceptible to cultural influence.     

Brightness and loudness as functions of stimulus duration

The brightness of white light and the loudness of white noise were measured by magnitude estimation for sets of stimuli that varied in intensity and duration. Brightness and loudness both grow as power functions of duration up to a critical duration, beyond which apparent magnitude is essentially independent of duration. For brightness, the critical duration decreases with increasing intensity, but for loudness the critical duration is nearly constant at about 150 msec. Loudness and brightness also grow as power functions of intensity. The loudness exponent is the same for all durations, but the brightness exponent is about half again as large for short durations as for long. The psychophysical power functions were used to generate equal-loudness and equal-brightness functions, which specify the combinations of intensity E and duration T that produce the same apparent magnitude. Below the critical duration ET equals k for equal brightness, and ET^a equals k for equal loudness. The value a is about 0.7 for threshold and about 1.25 for supraliminal loudness.

The finitude of life—How mortality salience affects consumer behavior: A review

The influence of mortality salience (MS) on consumer behavior has been well-established over the last 25 years. However, research findings have provided divergent insights with regard to the direction of its outcomes. This article provides a systematic review of the extant research stream thereby revealing how the differences are primarily due to the conceptualization and operationalization of MS. Based on a conceptual revision of MS, we suggest an extended definition of the concept. An extensive overview of empirical findings, together with a holistic presentation of influential factors, offers a foundation for further MS studies conducted in a consumer behavior context, concluding with an extensive research agenda.     

Electrophysiological correlates of dispositional mindfulness: A quantitative and complexity EEG study

While growing evidence supports that dispositional mindfulness relates to psychological health and cognitive enhancement, to date there have been only a few attempts to characterize its neural underpinnings. In the present study, we aimed at exploring the electrophysiological (EEG) signature of dispositional mindfulness using quantitative and complexity measures of EEG during resting state and while performing a learning task. Hundred twenty participants were assessed with the Five Facet Mindfulness Questionnaire and underwent 5 min eyes-closed resting state and 5 min at task EEG recording. We hypothesized that high mindfulness individuals would show patterns of brain activity related to (a) lower involvement of the default mode network (DMN) at rest (reduced frontal gamma power) and (b) a state of ‘task readiness’ reflected in a more similar pattern from rest to task (reduced overall q-EEG power at rest but not at task), as compared to their low mindfulness counterparts. Dispositional mindfulness was significantly linked to reduced frontal gamma power at rest and lower overall power during rest but not at task. In addition, we found a trend towards higher entropy during task performance in mindful individuals, which has recently been reported during mindfulness meditation. Altogether, our results add to those from expert meditators to show that high (dispositional) mindfulness seems to have a specific electrophysiological pattern characteristic of less involvement of the DMN and mind-wandering processes.     

When not teaming up puts parents at risk: Coparenting and parental burnout in dual-parent heterosexual families in Switzerland

Parental burnout refers to loss of energy and pleasure in the parental role. It is predictive of psychopathological outcomes in parents and dysfunctional parenting behaviors. Support of parental duties is central to alleviation of parental burden and prevention of burnout. Coparenting is the concept related to interparental mutual support in rearing a child. However, the links between coparenting and parental burnout have yet to be assessed. We thus aimed in this study to assess which dimensions of coparenting are linked with parental burnout. A total of 306 participants from the French-speaking part of Switzerland (120 fathers, 186 mothers) completed online questionnaires about parental burnout, their coparental relationship, and sociodemographic characteristics. We performed hierarchical regressions, entering sociodemographic characteristics in a first block and coparenting dimensions in a second block. Results showed that (i) a higher number of children and having younger children are linked to higher burnout; (ii) coparenting exposure to conflict is related to higher burnout, whereas endorsement of the partner's parenting is related to lower burnout; and (iii) no interaction effect occurs between sociodemographic characteristics and coparenting variables. Coparenting thus significantly contributes to the occurrence of burnout syndrome. Working on the coparental relationship preventively in parental educational programs or at a relational systemic level in therapy may help prevent burnout. Treating one parent only may not be sufficient to alleviate burnout, as negative coparenting could counter the effect of individual therapy.     

The gender-congruency effect in picture-word tasks

In Dutch noun phrases like “het boek” (the book) or “de kat” (the cat), the definite article (het or de) depends on the noun's grammatical gender (neuter or non-neuter). Schriefers reported that the production of a noun phrase like “het rode bed” (“the red bed”) in response to a colored picture takes less time when the picture is accompanied by a distractor word of congruent gender (e.g., “huis,” a het-word) than when it is accompanied by a word of incongruent gender (e.g., “hand,” a de-word). In three experiments we explored the characteristics of this gender-congruency effect. The following conclusions were reached. First, the gender-congruency effect is a rather robust phenomenon. Second, with the exception of a small effect in Exp. 2, no evidence was obtained for a gender-congruency effect when subjects were required to produce a single noun in response to a picture (e.g., “bed”). Third, the gender-congruency effect decreases with a decreasing familiarity of the distractor word. Implications for models of word production are discussed.

Alternative revision theories of truth

The Revision Theory of Truth (Gupta/Belnap 93) has been challenged in A. M. Yaqb's recent book The Liar Speaks the Truth. Yaqb suggests some non-trivial changes in the original theory — changing the limit rule — to avoid certain artifacts. In this paper it is shown that the proposed changes are not sufficient, i.e., Yaqb's system also produces artifacts. An alternative solution is proposed and the relation between it and Yaqb's solution is explored.     

Ability to stand alone and processing of open-class and closed-class words: Isolation versus context

Four experiments investigating processing of closed-class and open-class words in isolation and in sentence contexts are reported. Taft (1990) reported that closed-class words which could not meaningfully stand alone and open-class words which could not meaningfully stand alone incurred longer lexical decision responses than did control words. Taft also reported that closed-class and open-class words which could stand alone meaningfully were not associated with longer lexical decision responses than were control words. Experiments 1 and 2 replicated Taft 's effect of ability to stand alone on lexical decision responses to closed-class and open-class words presented in isolation. In Experiments 3 and 4, the same lexical decision targets were presented as part of semantically neutral context sentences in a moving window paradigm. The stand-alone effect was not present in Experiments 3 and 4. The results suggest Toft's conclusion that meaningfulness of a word influences lexical decision needs revision. An explanation is provided according to which support from message level and syntactic and lexical sources in sentence contexts influence words' perceived “meaningfulness.”
