VERBAL CONDITIONING AS A FUNCTION OF AWARENESS AND MANIFEST ANXIETY1

Les AA. examinent la relation entre anxiété et conditionnement verbal d'une part, anxiété et conscience du renforcement d'autre part, dans une épreuve de construction de phrases. L'analyse des résultats non concordants apparus dans les études antérieures et qui concernent la relation entre anxiété et conditionnement verbal suggère L'hypothèse que la direction de cette relation dépend de la conscience des sujets au cours du conditionnement. Les résultats présents montrent que les sujets conscients à forte anxiété se conditionnent mieux que les sujets conscients à faible anxiété. Mais les sujets non conscients à faible anxiété donnent significativement plus de réponses “Je-Nous” que les sujets non conscients à forte anxiété. La non-concordance avec les résultats antérieurs est sans doute due à des différences de population (sujets malades ou normaux).     

Progressive and regressive developmental changes in neural substrates for face processing: testing specific predictions of the Interactive Specialization account

Face processing undergoes a fairly protracted developmental time course but the neural underpinnings are not well understood. Prior fMRI studies have only examined progressive changes (i.e., increases in specialization in certain regions with age), which would be predicted by both the Interactive Specialization (IS) and maturational theories of neural development. To differentiate between these accounts, the present study also examined regressive changes (i.e., decreases in specialization in certain regions with age), which is predicted by the IS but not maturational account. The fMRI results show that both progressive and regressive changes occur, consistent with IS. Progressive changes mostly occurred in occipital-fusiform and inferior frontal cortex whereas regressive changes largely emerged in parietal and lateral temporal cortices. Moreover, inconsistent with the maturational account, all of the regions involved in face viewing in adults were active in children, with some regions already specialized for face processing by 5 years of age and other regions activated in children but not specifically for faces. Thus, neurodevelopment of face processing involves dynamic interactions among brain regions including age-related increases and decreases in specialization and the involvement of different regions at different ages. These results are more consistent with IS than maturational models of neural development.     

Are some gestalt principles deployed more readily than others during early development? The case of lightness versus form similarity

Four experiments investigated how readily infants achieve perceptual organization by lightness and form similarity. Infants were (a) familiarized with elements that could be organized into rows or columns on the basis of lightness or form similarity and tested with vertical versus horizontal bars depicting the familiar versus novel organization or (b) familiarized with bars and tested with elements. For lightness similarity, generalization occurred in both tasks; however, for form similarity, generalization occurred only in the elements --> bars task. The findings indicate that lightness similarity is more readily deployed than form similarity and are discussed in the context of (a) whether the difference reflects speed of application or experience-based learning, (b) evidence from visual agnosic patients and the time course of application of the principles in healthy adults, and (c) development of dorsal and ventral visual processing streams.     

A Pilot Study of a Mental Silence Form of Meditation for Women in Perimenopause

Menopausal symptoms often feature or are worsened by psychological and psychosomatic factors. As there is limited research into the potential role of psychological interventions, especially meditation, for the treatment of these symptoms the current study adopted an AB case series design with a follow-up phase. Fourteen women who were experiencing hot flashes and other menopausal symptoms and receiving no treatment for them attended meditation classes twice weekly for 8 weeks and practiced daily at home. A mental silence orientated technique of meditation called Sahaja Yoga (SYM) was taught. The Hot Flash Diary, Kupperman Index, MENQOL, Greene’s Climacteric Scale and STAI, were administered at baseline, mid treatment (4 weeks), post-treatment (8 weeks) and at 8 weeks follow-up. Substantial improvements in all measures occurred at post treatment. Changes in vasomotor symptoms, especially hot flashes, were most prominent as a significant decrease of 67% at post-treatment and 57% at follow-up (χ² = 11.7, p < .003) were noted and Kupperman’s Index score decreased by 58% at post-treatment and 40% at follow-up (χ² = 11.7, p < .005). All other symptom measures improved substantially from baseline to post-treatment, non-parametric analysis indicating that most of these changes were significant. These findings tentatively suggest that menopausal symptoms, especially vasomotor symptoms, and particularly hot flashes, might be substantially improved by using meditation.     

The development of expert face processing: are infants sensitive to normal differences in second-order relational information?

Sensitivity to second-order relational information (i.e., spatial relations among features such as the distance between eyes) is a vital part of achieving expertise with face processing. Prior research is unclear on whether infants are sensitive to second-order differences seen in typical human populations. In the current experiments, we examined whether infants are sensitive to changes in the space between the eyes and between the nose and the mouth that are within the normal range of variability in Caucasian female faces. In Experiment 1, 7-month-olds detected these changes in second-order relational information. Experiment 2 extended this finding to 5-month-olds and also found that infants detect second-order relations in upright faces but not in inverted faces, thereby exhibiting an inversion effect that has been considered to be a hallmark of second-order relational processing during adulthood. These results suggest that infants as young as 5 months are sensitive to second-order relational changes that are within the normal range of human variability. They also indicate that at least rudimentary aspects of face processing expertise are available early in life.

Language proficiency does not modulate executive control in older bilinguals

ABSTRACT

We examined if language proficiency modulates performance in tasks that measure executive control in older Telugu-English bilinguals (n = 50, mean age = 57.15 years). We administered numerical Stroop task, Attention Network Task, Dimensional Change Card Sorting task, and stop-signal task that are known to tap into different aspects of executive functioning on healthy aging Telugu-English bilinguals. Second language (English) proficiency was calculated as a cumulative score that considered both subjective and objective measures of L2 fluency and use. Bilinguals were divided into two groups based on the cumulative score and compared on each task. We did not find any effect of language proficiency on any of the executive control measures. The additional Bayesian analysis also supported these findings. Therefore, the results do not support the claim that bilingual language proficiency modulates executive control, at least in the elderly population. We discuss the results with regard to the issue of bilingual advantage in executive control and the role of age and language use.     

Attention in Sentence Processing: A Review

This review looks at the relationship between attention and language. There have been many studies that have shown a certain role of attention on sentence and spoken word processing. At the same time some other studies have observed that language processing is autonomous. In this review an attempt has been made to review the empirical evidence from sentence processing in reading, auditory processing and speaking domains to see if attentional manipulations cause interference with processing. The review suggests currently available evidence is rather mixed and it is still a long way to fully explore the attentional basis of sentence processing.
