Perceptual equivalence of acoustic cues in speech and nonspeech perception

Trading relations show that diverse acoustic consequences of minimal contrasts in speech are equivalent in perception of phonetic categories. This perceptual equivalence received stronger support from a recent finding that discrimination was differentially affected by the phonetic cooperation or conflict between two cues for the /slIt/-/splIt/contrast. Experiment 1 extended the trading relations and perceptual equivalence findings to the /sei/-/stei/contrast. With a more sensitive discrimination test, Experiment 2 found that cue equivalence is a characteristic of perceptual sensitivity to phonetic information. Using “sine-wave analogues” of the /sei/-/stei/stimuli, Experiment 3 showed that perceptual integration of the cues was phonetic, not psychoacoustic, in origin. Only subjects who perceived the sine-wave stimuli as “say” and “stay” showed a trading relation and perceptual equivalence; subjects who perceived them as nonspeech failed to integrate the two dimensions perceptually. Moreover, the pattern of differences between obtained and predicted discrimination was quite similar across the first two experiments and the “say”-“stay” group of Experiment 3, and suggested that phonetic perception was responsible even for better-than-predicted performance by these groups. Trading relations between speech cues, and the perceptual equivalence that underlies them, thus appear to derive specifically from perception of phonetic information.     

A reevaluation of the absenteeism-job satisfaction relationship

Previous reviews of the relationship of employee absenteeism to job satisfaction have largely neglected the size of the relationships reported and the artifacts that can affect statistical tests of significance. This paper applies the F. L. Schmidt-J. E. Hunter (1977, Journal of Applied Psychology, 62, 529-540) model of validity generalization in assessing the nature and strength of the relationship of absence to attitudes. Issues concerning the reliability and validity of absence measures are addressed, correlations between absence and job satisfaction are compiled and summarized, and an agenda for future research is set out. Considering the reliability estimates reported for the Frequency, Attitudinal, and Time Lost indices, the Time Lost Index was found to be the most reliable (r xx = .66, SD = .28). Factor analyses of intercorrelations among absence measures provided tentative support for a voluntary-involuntary absenteeism distinction. Combining all measures of satisfaction and all measures of absences, the mean correlation between absence and attitudes is -.09 (SD = .13). In addition to more comprehensive theory-guided multivariate research, future studies should aim toward a reconceptualization of absenteeism as a construct to take into consideration the perceptions of the workers themselves.     

Pushing dualism to an extreme: On the philosophical impetus of a new materialism

This article discusses the way in which a group of contemporary cultural theorists in whose work we see a “new materialism” (a term coined by Braidotti and DeLanda) at work constitutes a philosophy of difference by traversing the dualisms that form the backbone of modernist thought. Continuing the ideas of Lyotard and Deleuze they have set themselves to a rewriting of all possible forms of emancipation that are to be found. This rewriting exercise involves a movement in thought that, in the words of Bergson, can be termed “pushing dualism to an extreme.” By this movement, Deleuze has stated, “difference is pushed to the limit,” that is, using Colebrook’s words, “difference is shown differing.” The article addresses the ways in which modernity’s dualisms (structured by a negative relation between terms) are traversed, and how a new conceptualization, and ontology, of difference (structured by an affirmative relation) comes to be constituted along the way. New materialism leaves behind all prioritizations (implicitly) involved in modern dualist thinking since a difference structured by affirmation does not work with predetermined relations (e.g., between mind and body) nor does it involve a (counter-)hierarchy between terms. The article makes explicit the methodology of the current-day rise of non-dualist thought, both in terms of its non-classificatory mode of (Deleuzian) thinking and in terms of the theory of the time of thought thus effectuated (Lyotard’s notion of ‘rewriting modernity’ is not a post-modernism). Throughout the article we will engage with an example in order to demonstrate the ontology that is being practiced following this methodology: How does a new (feminist) materialism traverse the sexual dualisms that structure modernist (feminist) thinking? This example also shows how a feminist post-modernism (found in the canonical work of Butler) has remained dualist, and what makes new materialism “new.” Freed from a dualist methodology, the modernist emancipatory project comes to full fruition in new materialism.     

The Relationship of Drug Use to Suicide Ideation and Attempts Among African American,Hispanic, and White Non-Hispanic Male Adolescents

This study presents self-report cross-sectional and longitudinal data on associations between drug use, suicide ideation, and attempts in a multiethnic sample of seventh- and eighth-grade male adolescents attending school in the greater Miami, Florida, area. African Americans had the highest prevalence of 6-month ideation (20.5%), and Haitians had the highest attempts (11.4%). For the total sample, tranquilizers had the highest odds ratio for ideation (3.4), and PCP for attempts (6.2). Psychoactive drug-use was consistently related to attempts among Hispanics, white non-Hispanics, and African Americans. Acculturation strains interacted with cocaine and crack to predict suicide attempts among Hispanic respondents.     

Spendthrifts and Tightwads in Childhood: Feelings about Spending Predict Children's Financial Decision Making

Adults differ in the extent to which they find spending money to be distressing; “tightwads” find spending money painful, and “spendthrifts” do not find spending painful enough. This affective dimension has been reliably measured in adults and predicts a variety of important financial behaviors and outcomes (e.g., saving behavior and credit scores). Although children's financial behavior has also received attention, feelings about spending have not been studied in children, as they have in adults. We measured the spendthrift–tightwad (ST–TW) construct in children for the first time, with a sample of 5‐ to 10‐year‐old children (N = 225). Children across the entire age range were able to reliably report on their affective responses to spending and saving, and children's ST–TW scores were related to parent reports of children's temperament and financial behavior. Further, children's ST–TW scores were predictive of whether they chose to save or spend money in the lab, even after controlling for age and how much they liked the offered items. Our novel findings—that children's feelings about spending and saving can be measured from an early age and relate to their behavior with money—are discussed with regard to theoretical and practical implications.

Coping styles and self-regulation predict complementary and alternative medicine and herbal supplement use among college students

Studies have suggested that complementary and alternative medicine (CAM) and herbal supplement use may be high on college campuses. This study investigated the relationship between CAM and herbal supplement utilization and coping, self-regulatory, cognitive styles, and healthcare satisfaction among college students (n=370). Indeed, overall CAM and herbal supplement use during the past year appeared high; however, users of these practices appeared somewhat heterogeneous. Dispositional factors were predictive of utilization with active coping style associated with both practices, whereas support-seeking and intrinsic self-regulation were only associated with CAM use and avoidant coping was only related to use of herbal supplements. Notably, dissatisfaction with healthcare services was not associated with either CAM or herbal supplement use among students. The findings from this study offer insight regarding motives for usage that may assist in more openly dialoguing with students regarding their health-enhancing and/or health-compromising behaviors. Moreover, future studies assessing utilization of CAM will benefit from examining the definitional issues of CAM practices that are addressed.

Empathy is a beautiful thing: Empathy predicts imitation only for attractive others

Research shows that we spontaneously imitate people. Moreover, empathy predicts the degree of this non‐conscious imitation. Little is known, however, if or how this expression of empathy is influenced by stable physical characteristics of our interaction‐partners. In two studies, we tested whether attractiveness of others moderated the relation between empathy and imitation. While seeing a woman performing joystick movements, participants either imitated, or non‐imitated these movements. Results showed that the higher participants empathy score, the faster they imitated an attractive person. The level of empathy did not predict the degree of imitation of unattractive targets. The findings demonstrate that the expression of empathy through imitation can be moderated by attractiveness, thereby introducing a new dimension to the conditionality of empathy.     

Validation of a motivation-based typology of angry aggression among antisocial youths in Norway

This article describes the validation of the Angry Aggression Scales (AAS), the Behavior Inhibition System and the Behavior Activation System (BIS/BAS) scales, the reactive aggression and proactive power scales in relation to a Norwegian sample of 101 antisocial youths with conduct problems (64 boys, 37 girls, mean age 15 ± 1.3 years) and 101 prosocial controls matched on age, gender, education, ethnicity, and school district. Maximum likelihood exploratory factor analyses with oblique rotation were performed on AAS, BIS/BAS, reactive aggression and proactive power scales as well as computation of Cronbach's alpha and McDonald's omega. Tests for normality and homogeneity of variance were acceptable. Factor analyses of AAS and the proactive/reactive aggression scales suggested a hierarchical structure comprising a single higher-order angry aggression (AA) factor and four and two lower-order factors, respectively. Moreover, results suggested one BIS factor and a single higher-order BAS factor with three lower-order factors related to drive, fun-seeking and reward responsiveness. To compare scores of antisocial youths with controls, t-tests on the mean scale scores were computed. Results confirmed that antisocial youths were different from controls on the above-mentioned scales. Consistent with the idea that anger is associated with approach motivation, AAS scores correlated with behavioral activation, but only explosive/reactive and vengeful/ruminative AA correlated with behavioral inhibition. Results generally validated the quadruple typology of aggression and violence proposed by Howard (2009).
