Perceptual adaptation to sinewave-vocoded speech across languages

Listeners rapidly adapt to many forms of degraded speech. What level of information drives this adaptation, however, remains unresolved. The current study exposed listeners to sinewave-vocoded speech in one of three languages, which manipulated the type of information shared between the training languages (German, Mandarin, or English) and the testing language (English) in an audio-visual (AV) or an audio plus still frames modality (A + Stills). Three control groups were included to assess procedural learning effects. After training, listeners' perception of novel sinewave-vocoded English sentences was tested. Listeners exposed to German-AV materials performed equivalently to listeners exposed to English AV or A + Stills materials and significantly better than two control groups. The Mandarin groups and German-A + Stills group showed an intermediate level of performance. These results suggest that full lexical access is not absolutely necessary for adaptation to degraded speech, but providing AV-training in a language that is similar phonetically to the testing language can facilitate adaptation.     

Body Posture and the Feeling of Social Closeness: An Exploratory Study in a Naturalistic Setting

Previous research has shown that body postures and body movements influence people’s attitudes, preferences and feelings. In the present study, we explored the influence of body posture on the feeling of closeness towards others and how this effect may interact with contextual variables. Study 1 was conducted in a naturalistic setting in which 127 participants observed a series of live dance sequences either standing up or remaining seated. After each sequence, participants reported the feelings elicited by the dance performance on a questionnaire. Visibility of performers’ facial expressions and background tempo were used as contextual variables. Results showed that participants who watched the performance standing up felt significantly closer to the dancers than participants who remained seated. Study 2 was carried out in a laboratory setting to explore the relationship between body posture, tempo and heart rate. Results showed a significant increase in heart rate when standing compared to when sitting and no effect of tempo. The present research demonstrates a link between body posture and social connection providing evidence that standing up strengthens the feeling of closeness to others, and showing that posture not only has an impact on self-related feelings (e.g. fear, anger, sadness) as previous research has shown, but also has an impact on feelings towards others at the base of all human social relations. The present research also suggests that heart rate may be a mediator of the effect of posture on the feeling of closeness.     

The Priority Principle from Kant to Frege

In a famous passage (A68/B93), Kant writes that “the understanding can make no other use of […] concepts than that of judging by means of them.” Kant's thought is often called the thesis of the priority of judgments over concepts. We find a similar sounding priority thesis in Frege: “it is one of the most important differences between my mode of interpretation and the Boolean mode […] that I do not proceed from concepts, but from judgments.” Many interpreters have thought that Frege's priority principle is close to (or at least derivable from) Kant's. I argue that it is not. Nevertheless, there was a gradual historical development that began with Kant's priority thesis and culminated in Frege's new logic.     

Religious Schools,Home Schools,and the Timing of First Marriage and First Birth

The timing of individuals’ family formation is important for a number of socioeconomic and health outcomes. We examine the influence of religious schools and home schools on the timing of first marriage and first birth using data from the Cardus Education Study Graduate Survey (N = 1,496). Our results from life tables and event-history regression models show that, on average, graduates of evangelical Protestant schools—but not Catholic school or homeschool graduates—have earlier marriages and births than public school graduates. Catholic school students have later first births on average than public school graduates. Models interacting schooling type with age and age-squared suggest that evangelical schoolers’ higher odds of marriage stem from higher odds of marrying at ages 21–30, and their higher odds of first birth stem from higher odds of births from ages 25–34. Catholic school and nonreligious private school students also have higher odds of marrying in the mid-20s and early-30s than do public school students. Evangelical, non-religious private, and Catholic school students all have lower odds of teenage births than public school students but higher odds of birth later in the life course. Homeschoolers do not differ on either outcome at any age. Our findings suggest that schools socialize their students with distinctive attitudes toward family formation that influence their behavior even many years after graduation, though these schools do not appear to be particularly harmful to life chances in terms of fostering marriage or childbearing at very young ages.     

Memory search for the first target modulates the magnitude of the attentional blink

The resolution of temporal attention is limited in a manner that makes it difficult to identify two targets in short succession. This limitation produces the phenomenon known as the attentional blink (AB), in which processing of a first target (T1) impairs identification of a second target (T2). In the AB literature, there is broad agreement that increasing the time it takes to process T1 leads to a larger AB. One might, therefore, predict that increasing the number of possible T1 identities, or target set, from 1 to 16 would lead to a larger AB. We were surprised to find that this manipulation of T1 difficulty had no influence on AB magnitude. In subsequent experiments, we found that AB magnitude interacts with T1 processing time only under certain circumstances. Specifically, when the T1 task was either well masked or had to be completed online, we found a reliable interaction between AB magnitude and the target set size. When neither of these conditions was fulfilled, there was no interaction between target set size and the AB. Previous research found that when the target set changes from trial to trial, trials with more possible targets elicited a larger AB. In the present study, the target set is held constant, reducing the demands on working memory. Nevertheless, AB magnitude still interacts with target set size, as long as the T1 task cannot be processed offline. Thus, the act of searching memory delays subsequent processing, even when the role of working memory has been minimized.     

The beliefs that underlie autonomy-supportive and controlling teaching: A multinational investigation

We investigated the role of three beliefs in predicting teachers’ motivating style toward students—namely, how effective, how normative, and how easy-to-implement autonomy-supportive and controlling teaching were each believed to be. We further examined national collectivism–individualism as a predictor of individual teachers’ motivating style and beliefs about motivating style, as we expected that a collectivistic perspective would tend teachers toward the controlling style and toward positive beliefs about that style. Participants were 815 full-time PreK-12 public school teachers from eight different nations that varied in collectivism–individualism. All three teacher beliefs explained independent and substantial variance in teachers’ self-described motivating styles. Believed effectiveness was a particularly strong predictor of self-described motivating style. Collectivism–individualism predicted which teachers were most likely to self-describe a controlling motivating style, and a mediation analysis showed that teachers in collectivistic nations self-described a controlling style because they believed it to be culturally normative classroom practice. These findings enhance the literature on the antecedents of teachers’ motivating styles by showing that teacher beliefs strongly predict motivating style, and that culture informs one of these beliefs—namely, normalcy.     

Professional Identity Development: A Grounded Theory of Transformational Tasks of Counselors

The purpose of this qualitative grounded theory study was to investigate practicing counselors' professional identity development at nodal points during their career. Through the use of 6 focus groups of beginning, experienced, and expert counselors, 26 participants shared their experiences, and 6 themes emerged to form a theory of transformational tasks of professional identity development. Through these tasks, counselors encountered issues of idealism toward realism, burnout toward rejuvenation, and compartmentalization toward congruency.     

The Appearance‐Change Instruction Does Not Improve Line‐up Identification Accuracy

In many jurisdictions, police instruct a witness, before presenting a photo line‐up, that the suspect's appearance may be different in the photo than it was at the time of the crime. The experiments reported here examine the impact of this ‘appearance‐change instruction’ (ACI), exploring its effects with different crimes, perpetrators, line‐ups, and different phrasings of the ACI. The data indicate that the ACI increases witnesses' willingness to make a choice from a line‐up but does not increase accuracy. Copyright © 2013 John Wiley & Sons, Ltd.
