Effect of manipulating the risetime of an acoustic stimulus on two protective reflexes: cardiac defense and motor startle

Effect of manipulating the risetime of an acoustic stimulus on two protective reflexes: cardiac defense and motor startle. The risetime is a parametric characteristic of the eliciting stimulus frequently used to differentiate among psychophysiological reflexes. The aim of the present study was to examine the effect of manipulating the risetime of an acoustic stimulus on two protective reflexes: cardiac defense and motor startle. 100 participants underwent a psychophysiological reactivity test to five presentations of an intense acoustic stimulus (105 dB white noise) under one of five risetime conditions: 0, 24, 48, 96, and 240 ms. Total energy of the stimulus was controlled by increasing the base duration of the stimulus (1000 ms) by one third of the risetime. Results showed that risetime significantly affected motor startle but not cardiac defense. Startle amplitude decreased linearly with increasing risetime after 24 ms. On the other hand, repetition of the stimulus significantly affected cardiac defense but not motor startle. These results question the traditional differentiation between startle and defense based on risetime.     

Prejudice and attitudes of acculturation: perspectives of autochthonous and immigrants

This study is framed in a wider research on the acculturation process through a new acculturation model. The aim of this paper is to analyse the mutual prejudice between ethnic groups in contact and its relation to their preferred acculturation attitude. A questionnaire composed by various scales was given to four groups of people living in municipalities with high rate of African immigrants in Almería: Maghrebis, Sub-Saharans, Spaniards who evaluated the Maghreb out-group and Spaniards who responded on the Sub-Saharan out-group. The results obtained indicate a relation between prejudice and acculturation attitude, as the lowest scores in prejudice are hold in each group by people preferring integration , whilst the highest ones come from those who bow to exclusion/marginalisation.     

Emotional intelligence as predictor of mental, social, and physical health in university students

This study examined the association between emotional intelligence (EI), anxiety, depression, and mental, social, and physical health in university students. The sample was made up of 184 university students (38 men and 146 women). El was evaluated by the Trait Meta-Mood Scale (Salovey, Mayer, Goldman, Turvey, and Palfai, 1995), which evaluates the three dimensions (Attention, Clarity, and Mood Repair). Anxiety was evaluated with the Trait Anxiety Questionnaire (Spielberger, Gorsuch, Lushene, Vagg, and Jacobs, 1983) and depression with the Beck Depression Inventory (Beck, Rush, Shaw, and Emery, 1979). Mental, social, and physical health were evaluated with the SF-12 Health Survey (Ware, Kosinski, and Keller, 1996). Results showed that high Emotional Attention was positively and significantly related to high anxiety, depression, and to low levels of Role Emotional, Social Functioning, and Mental Health. However, high levels of emotional Clarity and Mood Repair were related to low levels of anxiety and depression, high Role Physical, Social Functioning, Mental Health, Vitality, and General Health. This study confirmed the predictive value of Attention, Clarity and Mood Repair regarding the levels of anxiety, depression, and areas related to mental, social, and physical health in university students.     

Pragmatism and Developmentalism in Brazilian Educational Thought in the 1950s/1960

This article proposes to analyse some aspects of the appropriation of New School thinking in Brazil, particularly Deweyan pragmatism, in the 1950s and 1960s. The analysis is based on the assumption that the developmentalist ideology that punctuated the debate on the economic, political and social restructuring of the country in these two decades constituted fertile ground for the return and expansion of pragmatist thinking amongst Brazilian educators, articulating itself, sometimes in contradictory ways, with this ideology. The focus of the analysis will be on the writings of the group of educators which circulated around the figure of Anísio Teixeira, at the time director of the National Institute for Pedagogic Studies (INEP), an organ linked to the Ministry of Education and Culture (MEC), which set itself the task of producing research that would support public policy in the field of education, as well as constituting itself as a center for teacher education and the stimulus and development of innovative experiences in the public school system. The appropriation of Deweyan pragmatism, in this context, had a triple perspective: pragmatism as scientific method, implying a specific conception of science, particularly the social sciences, with emphasis on the application of scientific knowledge in the solution of practical problems; as a way of democratic life; and as a synonym for experimentalism, in the sphere of schooling.     

Overt head movements and persuasion: a self-validation analysis

The authors report 3 experiments that examine a new mechanism by which overt head movements can affect attitude change. In each experiment, participants were induced to either nod or to shake their heads while listening to a persuasive message. When the message arguments were strong, nodding produced more persuasion than shaking. When the arguments were weak, the reverse occurred. These effects were most pronounced when elaboration was high. These findings are consistent with the "self-validation" hypothesis that postulates that head movements either enhance (nodding) or undermine (shaking) confidence in one's thoughts about the message. In a 4th experiment, the authors extended this result to another overt behavior (writing with the dominant or nondominant hand) and a different attitude domain (self-esteem).     

Aphemia after a penetrating brain wound: A case study

The speech of a patient with aphemia (pure anarthria) resulting from a penetrating brain wound was studied using linguistic and acoustic observations as well as electromyographic recordings from four labial muscles. The results are discussed in relation to phonetic disintegration's syndrome and apraxia of speech which, respectively, enhance linguistic disorders and motor programming disturbance.     

Innovative Moments as Developmental Change Levels: A Case Study on Meaning Integration in the Treatment of Depression

Innovative moments are alternative meanings to the problems expressed by clients and are organized into three levels. This study analyzes if these levels are not only change markers related to symptomatology outcomes, but also gradual steps in meaning development. A thematic analysis was carried out in a case of depression treated with narrative therapy. Results revealed three themes that evolved from level 1 to level 3. Levels 1 and 2 corresponded to one specific theme and almost all level 3 integrated different themes (polythematic). Level 3 innovative moments might be an integrative bridge allowing the construction of a more adaptive meaning framework.     

Polarization of perceived Procedural Justice

This study examined polarization of perceptions of Procedural Justice. Two polarization mechanisms are examined, Persuasive Arguments and Social Comparisons. Participants were students enrolled in a first-year introductory business class. There were 216 participants in the Persuasive Arguments study, 429 in the Social Comparisons study. The average age of all participants was 22.3 yr. (SD = 2.1); 56% were women. Fields of study represented were business, engineering, information technology, and sports. Analysis showed under conditions of low Procedural Justice, polarization effects were only found with the Persuasive Arguments mechanism. Under conditions of high Procedural Justice, polarization effects were only found with Social Comparisons. Implications for group polarization and Procedural Justice theories are considered.     

Hippocampal formation lesions impair performance in an odor-odor association task independently of spatial context

The rodent hippocampal system is known to play an important role in memory. Evidence that this role is not limited to spatial memory has come from studies using a variety of non-spatial memory tasks. One example is the social transmission of food preference paradigm, a task in which rats learn an odor-odor association with no explicit spatial memory component. However, because training and testing in this task typically take place in the same environment, it is possible that memory for the spatial context in which odors are experienced during training is critical to subsequent retention performance. If this is the case, it might be expected that lesions of the hippocampal system would impair memory performance by disrupting the establishment of a representation of the training environment. We addressed this issue by training rats in one spatial context and then testing them either in the same or a different spatial context. Normal control rats performed equally well when tested in an environment that was the same or different from that used during training, and the retention impairment exhibited by rats with hippocampus plus subiculum lesions was equivalent in the two test environments. These results support the view that the hippocampal system is necessary for the flexible expression of nonspatial memories even when the spatial context in which the memory is acquired is not critical to retrieval.
