Semantic interference on a phonological task in illiterate subjects

Previous research suggests that learning an alphabetic written language influences aspects of the auditory-verbal language system. In this study, we examined whether literacy influences the notion of words as phonological units independent of lexical semantics in literate and illiterate subjects. Subjects had to decide which item in a word- or pseudoword pair was phonologically longest. By manipulating the relationship between referent size and phonological length in three word conditions (congruent, neutral, and incongruent) we could examine to what extent subjects focused on form rather than meaning of the stimulus material. Moreover, the pseudoword condition allowed us to examine global phonological awareness independent of lexical semantics. The results showed that literate performed significantly better than illiterate subjects in the neutral and incongruent word conditions as well as in the pseudoword condition. The illiterate group performed least well in the incongruent condition and significantly better in the pseudoword condition compared to the neutral and incongruent word conditions and suggest that performance on phonological word length comparisons is dependent on literacy. In addition, the results show that the illiterate participants are able to perceive and process phonological length, albeit less well than the literate subjects, when no semantic interference is present. In conclusion, the present results confirm and extend the finding that illiterate subjects are biased towards semantic-conceptual-pragmatic types of cognitive processing.     

Contributions of the dorsal hippocampus and the dorsal subiculum to processing of idiothetic information and spatial memory

It is well established that the dorsal hippocampal formation is crucial for spatial memory in rats. However, little is known about the distinct functions of the dorsal hippocampus and the dorsal subiculum. To examine the role of the dorsal hippocampus and the dorsal subiculum, Long-Evans rats with excitotoxic lesions (NMDA) of the dorsal hippocampus (DH), the dorsal subiculum (DS), or both (DHDS), and controls were trained on a nonmatching-to-place task. Then, to identify the strategy used by each group, they were tested on the same task in the dark with the T-maze being rotated between the sample and the test runs. In the light, rats with combined lesions were impaired. In the dark, groups DH, DS, and controls performed near chance level except in trials without rotation, suggesting the use of a sense of direction. The same rats were trained on a radial-arm maze task. In the light, where proximal visual cues were accessible, combined lesions affected performance whereas in the dark, it was impaired by all lesions. This experiment demonstrated that the dorsal subiculum and the dorsal hippocampus play a crucial role in processing idiothetic information and/or in maintenance of this information in memory.     

The intuitive is a red herring

In this article, we discuss critically some of the key themes in Max Deutsch’s excellent book, The Myth of the Intuitive. We focus in particular on the shortcomings of his historical analysis – a missed opportunity by our lights, on the claim that philosophers present arguments in support of the judgments elicited by thought experiments, and on the claim that experimental philosophy is only relevant for the methodology of philosophy if thought experiments elicit intuitions.     

From Freudian narcissism to the Buddhist notion of anatman,via Jung's idea of identity

Starting from the question the youthful Carl Gustav pondered as he sat on ‘his’ stone – ‘Am I he who sits on the stone, or am I the stone on which he sits?’ – the author has attempted to show that, for Jung, the idea of identity is founded on a wilful non‐determination. This stance results in ethical and methodological repercussions that differentiate it both from the Freudian project and from Hindu and Buddhist thought, while at the same time having much in common with them. The paper refers to the notions of emergence and (Varela et al. 1992) enaction 2 2 According to the Wikipedia entry, the introduction of the term ‘enaction’ is attributed to Francisco Varela, Evan Thompson, and Eleanor Rosch (1992), who proposed the name to ‘emphasize the growing conviction that cognition is not the representation of a pre‐given world by a pre‐given mind but is rather the enactment of a world and a mind on the basis of a history of the variety of actions that a being in the world performs’.
and argues that the concept of the archetype, especially in relation to the self, merits a re‐evaluation in light of the new scientific paradigm.     

The Influence of Skill Development Training Program for Spiritual Care of Elderly Individual on Elderly Care Technician Students’ Perception of Spiritual Support

Spiritual care means helping an individual protect, maintain and gain all the dimensions of his/her existence. Elderly care technicians face numerous cases or crisis situations in which elderly individuals from different backgrounds question the meaning and value of life. Elderly care technicians must acknowledge that the spirituality is an important element in the way an elderly individual receives healthcare and they must be equipped for this matter. This study was conducted in order to examine the influence of “Skill Development Training Program for Spiritual Care of Elderly Individual,” which was carried out with students from elderly care program, on the perception of spirituality support in a pretest–posttest quasi-experimental study design with control group. As the data collection form, “Spiritual Support Perception” (SSP) scale was used. The mean scores of the intervention group after the training and after one month are 50.39 ± 5.34 and 51.13 ± 4.98, respectively, and those of the control group are 43.16 ± 4.83 and 42.72 ± 4.48. A statistically significant difference was found between the mean scores of the intervention group from the pretest and the posttests immediately after the training and one month after the training (f = 94.247, p = 0.001). In the control group, however, there was no significant change in the SSP mean scores (f = 0.269, p = 0.77). As a result, this study pointed out the necessity of such training programs for healthcare professionals to make a distinction between their professional duties and their own personalities in order to offer spiritual care to the elderly individual.     

Resurgence of time allocation

The resurgence of time allocation with pigeons was studied in three experiments. In Phase 1 of each experiment, response‐independent food occurred with different probabilities in the presence of two different keylights. Each peck on the key changed its color and the food probability in effect. In Phase 2, the food probabilities associated with each keylight were reversed and, in Phase 3, food was discontinued in the presence of either keylight. The food probabilities were .25 and .75, in Experiment 1, and 0.0 and 1.0 in Experiment 2. More time was allocated to the keylight correlated with more probable food in Phases 1 and 2, and in Phase 3 resurgence of time allocation occurred for two of three pigeons in Experiment 1, and for each of four pigeons in Experiment 2. Because time had to be allocated to either of the two alternatives in Experiments 1 and 2, however, it was difficult to characterize the time allocation patterns in Phase 3 as resurgence when changeover responding approached zero. In Experiment 3 this issue was addressed by providing a third alternative uncorrelated with food such that in each phase, after 30 s in the presence of either keylight correlated with food, the third alternative always was reinstated, requiring a response to access either of the two keylights correlated with food. In this experiment, the food probabilities were similar to those in Experiment 1. Resurgence of time allocation occurred for each of three pigeons under this procedure. The results of these experiments suggest that patterns of time allocation resurge similarly to discrete responses and to spatial and temporal patterns of responding.     

Clustering and switching in unconstrained,phonemic and semantic verbal fluency: the role of age and school type

We investigated the role of age and school type on clustering and switching in verbal fluency tasks (VFTs) with Brazilian children. The children were administered unconstrained, phonemic and semantic VFTs with a duration of 150 or 120 s, respectively. Both age and school type influenced all variables and in terms of performance over time. Older children and private school students outperformed the remainder of the sample, with the first 30 s of each VFT usually being the most productive. Although the size of the clusters produced did not differ between groups, the types of clusters did show some variations, with semantic clusters being the most frequent. Our results revealed strong correlations between switching ability and word production in all three VFTs. In conclusion, the executive functions known as planning and cognitive flexibility play a crucial role in word production by organising and facilitating the recall of lexical information from memory.     

Social Media and Language Processing: How Facebook and Twitter Provide the Best Frequency Estimates for Studying Word Recognition

Corpus‐based word frequencies are one of the most important predictors in language processing tasks. Frequencies based on conversational corpora (such as movie subtitles) are shown to better capture the variance in lexical decision tasks compared to traditional corpora. In this study, we show that frequencies computed from social media are currently the best frequency‐based estimators of lexical decision reaction times (up to 3.6% increase in explained variance). The results are robust (observed for Twitter‐ and Facebook‐based frequencies on American English and British English datasets) and are still substantial when we control for corpus size.     

BIOLOGY TEACHERS’ CONCEPTIONS ABOUT THE ORIGIN OF LIFE IN BRAZIL,ARGENTINA, AND URUGUAY: A COMPARATIVE STUDY

Teachers’ conceptions about the origin of life in three Latin American countries with contrasting levels of secularism were analyzed: Argentina (Catholic constitution), Brazil (formally secular but not in practice), and Uruguay (consolidated secularism). A European survey questionnaire was used and the interpretation of the results drew on Barbour's four categories concerning the relationships of science and religion. A large majority of Argentinian and Uruguayan teachers were clearly evolutionist, even when believing in God (Independence or Dialogue category), with no difference between Argentina and Uruguay. The majority of Brazilian teachers assumed a religious position about the origin of life, being creationist (Conflict or Independence categories) or evolutionary creationist (Dialogue or Integration categories). Differences of Brazilian teachers’ conceptions may result from the higher percentage of evangelicals and lower proportion of agnostics/atheists. Brazilian Catholic teachers were more creationist than their Catholic colleagues in Argentina and Uruguay. Distinct patterns were found, but further research is needed to understand possible classroom impacts.
