The processing of consonants and vowels during letter identity and letter position assignment in visual-word recognition: an ERP study

Recent research suggests that there is a processing distinction between consonants and vowels in visual-word recognition. Here we conjointly examine the time course of consonants and vowels in processes of letter identity and letter position assignment. Event related potentials (ERPs) were recorded while participants read words and pseudowords in a lexical decision task. The stimuli were displayed under different conditions in a masked priming paradigm with a 50-ms SOA: (i) identity/baseline condition e.g., chocolate-CHOCOLATE); (ii) vowels-delayed condition (e.g., choc_l_te-CHOCOLATE); (iii) consonants-delayed condition (cho_o_ate-CHOCOLATE); (iv) consonants-transposed condition (cholocate-CHOCOLATE); (v) vowels-transposed condition (chocalote-CHOCOLATE), and (vi) unrelated condition (editorial-CHOCOLATE). Results showed earlier ERP effects and longer reaction times for the delayed-letter compared to the transposed-letter conditions. Furthermore, at early stages of processing, consonants may play a greater role during letter identity processing. Differences between vowels and consonants regarding letter position assignment are discussed in terms of a later phonological level involved in lexical retrieval.     

Multisensory integration affects visuo-spatial working memory

In the present study, we investigate how spatial attention, driven by unisensory and multisensory cues, can bias the access of information into visuo-spatial working memory (VSWM). In a series of four experiments, we compared the effectiveness of spatially-nonpredictive visual, auditory, or audiovisual cues in capturing participants' spatial attention towards a location where to-be-remembered visual stimuli were or were not presented (cued/uncued trials, respectively). The results suggest that the effect of peripheral visual cues in biasing the access of information into VSWM depend on the size of the attentional focus, while auditory cues did not have direct effects in biasing VSWM. Finally, spatially congruent multisensory cues showed an enlarged attentional effect in VSWM as compared to unimodal visual cues, as a likely consequence of multisensory integration. This latter result sheds new light on the interplay between spatial attention and VSWM, pointing to the special role exerted by multisensory (audiovisual) cues.     

Time in language: event duration in language comprehension

This work investigates how we process and represent event duration in on-line language comprehension. Specifically, it examines how events of different duration are processed and what type of knowledge underlies their representations. Studies 1–4 examined verbs and phrases in different contexts. They showed that durative events took longer to process than non-durative events and that the duration attributed to the stimulus events correlated with on-line processing times. Studies 5 and 6 indicated that durative events occur in semantically more diverse contexts and elicit semantically more diverse associations than non-durative events. Semantic and contextual diversity also correlated with attributed durations and processing times. Results indicate that (a) event-specific durations are computed on-line from multiple unfolding cues, (b) processing cost and duration representations emerge from semantic and contextual diversity reflecting our experience, and (c) key components of duration representations may be situation-specific knowledge of causal and contingency relations between events.     

Seven-month-olds detect ordinal numerical relationships within temporal sequences

Previous evidence has shown that 11-month-olds represent ordinal relations between purely numerical values, whereas younger infants require a confluence of numerical and non-numerical cues. In this study, we show that when multiple featural cues (i.e., color and shape) are provided, 7-month-olds detect reversals in the ordinal direction of numerical sequences relying solely on number when non-numerical quantitative cues are controlled. These results provide evidence for the influence of featural information and multiple cue integration on infants’ proneness to detect ordinal numerical information.     

Religion,Health, and Psychological Well-Being

This study compares the effects of religiosity on health and well-being, controlling for work and family. With 2006 GSS data, we assess the effects of religiosity on health and well-being, net of job satisfaction, marital happiness, and financial status. The results indicate that people who identify as religious tend to report better health and happiness, regardless of religious affiliation, religious activities, work and family, social support, or financial status. People with liberal religious beliefs tend to be healthier but less happy than people with fundamentalist beliefs. Future research should probe how religious identity and beliefs impact health and well-being.     

Assessment of emotional reactivity produced by exposure to virtual environments in patients with eating disorders.

The aim of this study was to assess the usefulness of virtual environments representing situations that are emotionally significant to subjects with eating disorders (ED). These environments may be applied with both evaluative and therapeutic aims and in simulation procedures to carry out a range of experimental studies. This paper is part of a wider research project analyzing the influence of the situation to which subjects are exposed on their performance on body image estimation tasks. Thirty female patients with eating disorders were exposed to six virtual environments: a living-room (neutral situation), a kitchen with high-calorie food, a kitchen with low-calorie food, a restaurant with high-calorie food, a restaurant with low-calorie food, and a swimming-pool. After exposure to each environment the STAI-S (a measurement of state anxiety) and the CDB (a measurement of depression) were administered to all subjects. The results show that virtual reality instruments are particularly useful for simulating everyday situations that may provoke emotional reactions such as anxiety and depression, in patients with ED. Virtual environments in which subjects are obliged to ingest high-calorie food provoke the highest levels of state anxiety and depression.     

Adolescence and the Changing Context of Optimal Experience in Time: Italy 1986–2000

This study focused on the daily activities and related quality of experience of two distinct groups of Italian high school students analyzed in 1986 and 2000. Altogether, 120 participants, aged between 15 and 18, were administered the experience sampling method, a procedure providing on-line repeated samplings of daily time budget and associated quality of experience. In particular, attention was paid to optimal experience, characterized by a balance between environmental challenges and personal skills, intrinsic motivation, involvement, and well-being. In spite of the time gap, no major differences in the daily activity distribution were detected. Adolescents in both groups spent most of their time studying at school and at home, interacting, watching TV, carrying out maintenance, and engaging in structured leisure activities. The use of new technologies (computers, internet, mobile phones) emerged in the data gathered in 2000. As concerns the quality of experience, each daily activity showed a specific experiential profile recurring in both groups. Studying at home and engaging in structured leisure activities were primarily associated with optimal experience, as was using new technologies in 2000. These results shed light on students' preferential engagement in specific domains and allowed us to explore the active role of adolescents in shaping their future. Findings also highlighted the importance of providing adolescents with meaningful activities in order to foster their personal growth, well-being, and social integration.     

Observing home-visiting quality at scale with the home visit rating scales and a supervisor checklist in Peru

As home-visiting programs expand, there is a need to develop cost-effective tools to monitor their quality at scale. We compare the Home Visit Rating Scales (HOVRS), an instrument to measure home-visit process quality widely used in the United States, to a checklist designed for the Peruvian national home-visiting program, Cuna Mas. Both instruments were administered to a sample of 554 home visits and an equal number of mother–child dyads by their 176 home visitors. While the HOVRS was scored on video recordings of the visits by trained coders, the checklist was scored live by Cuna Mas supervisors. We assessed the validity of both measures in their first application in rural Peru, compared their performance, and selected a subset of items in the checklist to propose a simplified, shorter, and more cost-efficient instrument. To this end, we reorganized checklist items into constructs that best mapped those covered by the HOVRS and selected the highest performing according to predefined criteria. We found that both the HOVRS and the checklist had high reliability and acceptable levels of validity. We argue that the simplified checklist could prove useful for quality monitoring of service delivery of at-scale home-visiting programs and as a tool to support in-service training.
