Mood and fluency: The case of pronunciation ease,liking and trust

We explored the impact of mood on the judgemental consequences of word pronounceability in six Experiments (1 preregistered, total N = 1183). Positive and negative mood was induced via video clips (all but Experiment 4) and subliminal affective primes (Experiment 4). Additionally, participants were presented with easy- and difficult-to-pronounce letter strings. These were framed as target words to be judged for liking (Experiments 1–2), as names of eBay sellers to be judged for trustworthiness (Experiments 3–5), or as either seller names or passwords to provoke opposing interpretations of pronunciation fluency (Experiment 6). While pronounceability showed a robust effect across experiments, mood did not modulate the judgemental use of (Experiments 1–4), the correction for (Experiment 5) and the interpretation (Experiment 6) of word pronounceability. In conclusion, the judgemental effects of pronounceability persist despite the presence of more objective and task-pertinent cues, resist judgemental correction and remain unaffected by affective states.     

Expertise and error in diagnostic reasoning

An investigation is presented in which a computer simulation model (DIAGNOSER) is used to develop and test predictions for behavior of subjects in a task of medical diagnosis. The first experiment employed a process-tracing methodology in order to compare hypothesis generation and evaluation behavior of DIAGNOSER with individuals at different levels of expertise (students, trainees, experts). A second experiment performed with only DIAGNOSER identified conditions under which errors in reasoning in the first experiment could be related to interpretation of specific data items. Predictions derived from DIAGNOSER's performance were tested in a third experiment with a new sample of subjects. Data from the three experiments indicated that (1) form of diagnostic reasoning was similar for all subjects trained in medicine and for the simulation model, (2) substance of diagnostic reasoning employed by the simulation model was parable with that of the more expert subjects, and (3) errors in subjects' reasoning were attributable to deficiencies in disease knowledge and the interpretation of specific patient data cues predicted by the simulation model.     

The right thing to do or the smart thing to do? How communicating moral or business motives for diversity affects the employment image of Dutch public and private sector organizations

Many organizations have diversity statements in place in which they publicly declare their appreciation of and commitment to workforce diversity. These statements can either contain moral motives (e.g., “diversity reduces social inequalities”), business motives (e.g., “diversity enhances innovation”), or a combination of moral and business motives. In a desk study involving 182 Dutch organizations, we found that (a) private sector organizations more often than public sector organizations communicate business motives, (b) that public and private sector organizations are equally likely to communicate moral motives, and (c) that public sector organizations more frequently than private sector organizations communicate a combination of moral and business motives. Next, we used an experimental design to examine the causal influence of communicating different diversity motives on organizations' employment image (i.e., perceptions of organizational morality, competence, and attractiveness) among prospective employees (n = 393). Here, we used a scenario in which a healthcare organization was portrayed as either a public or a private sector organization and communicated either only moral motives, only business motives or a combination of moral and business motives for diversity. We found that for a public sector organization communicating moral instead of business motives for valuing diversity induced a more favorable employment image. For a private sector organization, there were no differences in employment image depending on the motive communicated. Together, these two studies shed new light on the role of diversity motives in establishing a positive employment image.     

The Effects of Oral and Silent Reading on Reading Comprehension

This study examined the effects of reading mode (oral and silent) and text genre (narrative and expository) on fourth graders’ reading comprehension. While controlling for prior reading ability of 48 participants, we measured comprehension. Using a repeated measured design, data were analyzed using analysis of covariance, paired t-tests, and correlational statistics. Results revealed that silent reading was stronger for narrative passages in retell measures, but there was no difference for comprehension questions. The expository passages revealed no difference between the reading modes. Comprehension of narrative texts was consistently stronger than expository texts in both silent and oral reading.     

Quality of Life (QoL) in a Brazilian Sample of Older Adults: The Role of Sociodemographic Variables and Depression Symptoms

The aim of the present study was to identify relevant variables associated with Quality of Life (QoL) in older adults. Older adults, up to 60 years old, were interviewed. Subjects were recruited through convenience sampling. 339 paticipants, who were stratified by gender, age, and subjective perception of health and illness, answered questions on sociodemographic issues, QoL (WHOQOL-100) and depressive symptomathology (Beck Depression Inventory—BDI). The multiple linear regression analysis showed associations of overall perception of QoL with depression levels, subjective perception of health status and gender. The individual analysis of each domain concluded that depression levels are correlated to all QoL domains, while health status was associated with physical, psychological, independence level and social relationship domains. Other variables were also assessed. The assessment of older adults concerning their QoL perceptions is associated with gender, age, marital status, social class, literacy rate, perception of health, and more substantially associated with depressive symptoms levels. Nevertheless, some limitations of this study and further ones are suggested.     

Absolute and relative pitch: Global versus local processing of chords

Absolute pitch (AP) is the ability to identify or produce notes without any reference note. An ongoing debate exists regarding the benefits or disadvantages of AP in processing music. One of the main issues in this context is whether the categorical perception of pitch in AP possessors may interfere in processing tasks requiring relative pitch (RP). Previous studies, focusing mainly on melodic and interval perception, have obtained inconsistent results. The aim of the present study was to examine the effect of AP and RP separately, using isolated chords. Seventy-three musicians were categorized into four groups of high and low AP and RP, and were tested on two tasks: identifying chord types (Task 1), and identifying a single note within a chord (Task 2). A main effect of RP on Task 1 and an interaction between AP and RP in reaction times were found. On Task 2 main effects of AP and RP, and an interaction were found, with highest performance in participants with both high AP and RP. Results suggest that AP and RP should be regarded as two different abilities, and that AP may slow down reaction times for tasks requiring global processing.
