Experiencing extinction within a task makes nonextinguished information learned within a different task context-dependent

In two experiments with rats, we analyzed the effect of experiencing extinction in one task on the context specificity of a new association learned within a different task. Rats were trained to run in a runway for water in Task 1, and received taste aversion conditioning in Task 2 (the tasks were reversed in Exp. 2). Half of the rats received conditioning and extinction of Task 1 in Context A, whereas the other half received no extinction. Then all animals received training in the alternate task in Context B, prior to testing in Context C. When they were tested in Context C, Task 2 performance was attenuated if Task 1 had been extinguished prior to Task 2. These results are similar to those we have reported in humans, and consistent with the idea that extinction prompts attention to contexts, regardless of whether or not the contexts were involved in extinction.     

Ranking 2010 in production and research productivity in Spanish public universities

The creation of the European Higher Education Area has brought the relevance of the scientific quality assessment in higher education. The result of this interest is a growing interest in the development of rankings of universities, both nationally and internationally. To continue the line started two years ago, the goal of this research is to update the ranking of research productivity in Spanish public universities with the data of 2010. We follow the same methodology to data from 2008 and 2009; although this year it includes measures of total production. The same indicators to evaluate research in 2009: journals articles indexed in the JCR, research periods, research + development projects, doctoral dissertations, grants for training university teachers, Doctoral Programs with Quality Mention and patents. From the results obtained show that universities with higher production were Complutense de Madrid, Barcelona and Granada. The most productive were the Pompeu Fabra University, the Pablo de Olavide, and the Autonoma de Barcelona.     

Considerations for Culturally Competent Cognitive-Behavioral Therapy for Depression with Hispanic Patients

The purpose of this paper is to outline considerations for adapting cognitive-behavioral therapy (CBT) to Hispanic patients who have recently immigrated, particularly those presenting with depressive symptoms. Culturally competent CBT is framed within a model originally proposed by Rogler and his colleagues (1987). The considerations outlined by the model include ensuring that treatments provide access, are selected based on compatibility with Hispanic culture, and are adapted to fit the culture. Recommendations for culturally adapting CBT include consideration of each patient's unique ethnocultural background and their treatment expectations, as well as culturally relevant interpersonal styles, values, and metaphors/language. In addition, specific strategies for conceptualizing and conducting CBT techniques are discussed.     

Prenatal daily musical exposure is associated with enhanced neural representation of speech fundamental frequency: Evidence from neonatal frequency-following responses

Fetal hearing experiences shape the linguistic and musical preferences of neonates. From the very first moment after birth, newborns prefer their native language, recognize their mother's voice, and show a greater responsiveness to lullabies presented during pregnancy. Yet, the neural underpinnings of this experience inducing plasticity have remained elusive. Here we recorded the frequency-following response (FFR), an auditory evoked potential elicited to periodic complex sounds, to show that prenatal music exposure is associated to enhanced neural encoding of speech stimuli periodicity, which relates to the perceptual experience of pitch. FFRs were recorded in a sample of 60 healthy neonates born at term and aged 12–72 hours. The sample was divided into two groups according to their prenatal musical exposure (29 daily musically exposed; 31 not-daily musically exposed). Prenatal exposure was assessed retrospectively by a questionnaire in which mothers reported how often they sang or listened to music through loudspeakers during the last trimester of pregnancy. The FFR was recorded to either a /da/ or an /oa/ speech-syllable stimulus. Analyses were centered on stimuli sections of identical duration (113 ms) and fundamental frequency (F₀ = 113 Hz). Neural encoding of stimuli periodicity was quantified as the FFR spectral amplitude at the stimulus F₀. Data revealed that newborns exposed daily to music exhibit larger spectral amplitudes at F₀ as compared to not-daily musically-exposed newborns, regardless of the eliciting stimulus. Our results suggest that prenatal music exposure facilitates the tuning to human speech fundamental frequency, which may support early language processing and acquisition.

Research Highlights

• Frequency-following responses to speech were collected from a sample of neonates prenatally exposed to music daily and compared to neonates not-daily exposed to music.
• Neonates who experienced daily prenatal music exposure exhibit enhanced frequency-following responses to the periodicity of speech sounds.
• Prenatal music exposure is associated with a fine-tuned encoding of human speech fundamental frequency, which may facilitate early language processing and acquisition.
