Capacity demands of phoneme selection in word production: new evidence from dual-task experiments

Three dual-task experiments investigated the capacity demands of phoneme selection in picture naming. On each trial, participants named a target picture (Task 1) and carried out a tone discrimination task (Task 2). To vary the time required for phoneme selection, the authors combined the targets with phonologically related or unrelated distractor pictures (Experiment 1) or words, which were clearly visible (Experiment 2) or masked (Experiment 3). When pictures or masked words were presented, the tone discrimination and picture naming latencies were shorter in the related condition than in the unrelated condition, which indicates that phoneme selection requires central processing capacity. However, when the distractor words were clearly visible, the facilitatory effect was confined to the picture naming latencies. This pattern arose because the visible related distractor words facilitated phoneme selection but slowed down speech monitoring processes that had to be completed before the response to the tone could be selected.     

Equivalence of a measurement model of cognitive abilities in U.S. standardization and Australian neuroscience samples

A psychological measurement model provides an explicit definition of (a) the theoretical and (b) the numerical relationships between observed scores and the latent variables that underlie the observed scores. Examination of the metric invariance of a measurement model involves testing the hypothesis that all components of the model relating observed scores to latent variables are equal across groups. The assumption of metric invariance is necessary for simple interpretation of scores. Establishing metric invariance also has implications for interpretation of convergent and divergent validity and patterns of deficit or disability. In this study the equivalence of the measurement model derived from the U.S. Wechsler Adult Intelligence Scale-III standardization sample was compared with a heterogeneous neurosciences sample in Australia. A pattern of strict metric invariance was observed across samples. These results provide evidence of the generality of the model underlying measurement of cognitive abilities.     

The impact of relational demographics on perceived managerial trustworthiness: similarity or norms?

Perceived trustworthiness is a critical antecedent of interpersonal trust, yet researchers have a limited understanding of how such perceptions are generated. The authors used 2 competing perspectives within the relational demography literature--similarity-attraction and relational norms--to empirically examine the effect of demographic differences. Whereas the similarity-attraction account suggests that subordinates will perceive their managers as more trustworthy when managers and staff are similar in demographic attributes, the relational norms account proposes that subordinates will perceive their managers as more trustworthy when their demographic differences follow normative expectations. Data collected from a field study of 178 manager-subordinate dyads in Hong Kong and Macau support the relational norms account in terms of education and organizational rank. The authors discuss the theoretical and practical implications of the study.

Maintained attitudinal changes in nursing personnel after a brief training on suicide prevention

Nursing personnel (N = 317) working at a general hospital attended a 6-hour training program on suicide prevention. They answered anonymously pre- and post-training the Suicide Behavior Attitude Questionnaire (SBAQ), which comprises 21 visual analogue scale items divided in three factorial subscales. The results indicated there were positive changes in the attitudes and these gains were significantly maintained at the 6-month follow-up evaluation. Improvement was in the Feelings and Professional Capacity subscales (ANOVA; p = 0.0001 and 0.01, respectively). There was no change on the Right to Suicide subscale. Because attitudes influence the effectiveness of health care personnel interventions, our findings may have important implications for the development of suicide prevention programs.     

I felt low and my purse feels light: depleting mood regulation attempts affect risk decision making

We propose that negative affect can induce people to engage in risky decisions. We test two alternative hypotheses as to how this effect may emerge. The mood repair hypothesis states that risky choices in risk decision making serve as a means to repair one's negative affect. The depletion hypothesis, in contrast, states that risky choices in risk decision making are the mere consequence of a state of depletion resulting from engagement in active mood regulation attempts. The results of a first laboratory study establish a link between risky choices in risk decision making and negative affect. Subsequent experiments provide evidence that depletion due to active mood regulation attempts, rather than mood repair, is the underlying process for this link.

Person-organization fit: Testing socialization and attraction-selection-attrition hypotheses

Using the socialization and attraction-selection-attrition (ASA) frameworks, this study examined the relation between employees’ work values and their organization’s values (person-organization fit). With a two year time interval, 140 respondents participated in a longitudinal study. After entry, socialization served to enhance homogeneity. The work values underwent small changes and the perception of fit with the organization grew. Despite high retention rates results confirmed the attrition effect. Results indicated that the lower the perceived match between own and organizational values at entry, the more likely it was that someone left the organization over time. We concluded that socialization as well as attrition mechanisms were present at the same time.     

What is a Truth Value And How Many Are There?

Truth values are, properly understood, merely proxies for the various relations that can hold between language and the world. Once truth values are understood in this way, consideration of the Liar paradox and the revenge problem shows that our language is indefinitely extensible, as is the class of truth values that statements of our language can take – in short, there is a proper class of such truth values. As a result, important and unexpected connections emerge between the semantic paradoxes and the set-theoretic paradoxes.     

Nature,Red in Tooth and Claw<Superscript>1</Superscript>

“Nature, Red in Tooth and Claw” explores Adorno’s ideas about our mediated relationship with nature. The first section of the paper examines the epistemological significance of his thesis about the preponderance of the object while describing the Kantian features in his notion of mediation. Adorno’s conception of nature will also be examined in the context of a review of J. M. Bernstein’s and Fredric Jameson’s attempts to characterize it. The second section of the paper deals with Adorno’s Freudian account of internal nature. While arguing against Joel Whitebook’s view that Adorno needs a concept of sublimation, I contend that Adorno’s genetic account of the relationship between nature and mind enables him to respond to the Freudian injunction to displace the id with the ego with a view to fostering autonomy. In the final section of the paper, problems with Adorno’s ideas about external and internal nature are briefly discussed. In Marx’s Ecology: Materialism and Nature (New York: Monthly Review Press, 2000) p. 195, John Bellamy Foster remarks on this line from Alfred Lord Tennyson ’s In Memoriam, claiming that it was widely known for “anticipating ”Darwinian’ ideas,’’ including much-maligned and heretical (at the time) materialist doctrines.
