Developmental change in fetal response to repeated low-intensity sound

The aim of this study was to investigate developmental changes in heart rate response to repeated low-intensity (85 dB) sound stimulation in fetuses between 32 and 37 weeks of gestation. We measured amplitude changes in heart rate as our index of fetal response. At 35 to 37 weeks of gestation, the majority of fetuses showed a deceleratory response at the first trial. Amplitude decreased with further trials using the same stimulus before recovering when exposed to another type of stimulation. In contrast, responses in fetuses at 32 to 34 weeks of gestation were variable across trials and there was no recovery with exposure to another type of stimulation. Our results suggest that fetal habituation of cardiac response changes with developmental age.     

From pregnancy to motherhood: The structure of representative and narrative change

The aim of this work was to identify ways of objectifying the course of mothers' represen tations of their babies and themselves as mothers during pregnancy and the postpartum period. A sample of 51 women attending a Family Guidance Clinic for psychoprophylaxis courses was studied using semistruc tured interviews that were administered in the 7th month of pregnancy and on the 5th day and in the 4th month postpartum. This paper describes a method for classifiying themes identified in the mothers' representations of the baby and of the self-as-mother as wish-organized, defense-organized, fear-organized, or disorganized. This classification derives from the presumed clinical function of the narrative themes in the mothers' representational world. Themes about the baby and about the self-as-mother were primarily fear-organized at the 7th month of pregnancy. On the 5th day postpartum, there was no prevailing thematic organization. At 4 months postpartum, representations of the baby were primarily fear-organized and almost never disorganized. We speculate that themes about the baby and the self-as-mother that are disorganized may have negative prognostic significance.     

Taking Care of Each Other: How Can We Increase Compliance with Personal Protective Measures During the COVID-19 Pandemic in Chile?

In the context of the COVID-19 pandemic, personal protective measures (e.g., social distancing, handwashing, and mask wearing) have been adopted as a cornerstone to limit the spread of the disease. Yet, the effectiveness of these measures depends on people's levels of adherence. In this article, we apply social-psychological research to the study of compliance with personal protective measures during the COVID-19 pandemic in Chile. We consider three possible models underlying adherence: (1) sociodemographic and socioeconomic factors, (2) instrumental factors, and (3) normative factors. We draw on data from a longitudinal nonrepresentative panel study (Study 1, n = 32,304) and a cross-sectional representative survey (Study 2, n = 1,078) to explore the impact of these different factors on personal protective measures compliance. Findings show the strongest support for the role of instrumental and normative factors, in that people who comply with protective measures report to a greater extent that relatives and friends comply too and tend to perceive high risk of COVID-19. We finish by proposing policy recommendations to promote effective strategies to contain the spread of the virus.     

Self-projection in middle childhood: a study on the relationship between theory of mind and episodic future thinking

Cognitive Processing - Growing evidence suggests that theory of mind (ToM) and episodic future thinking (EFT) are closely related at both brain and functional level. This study explored the...     

Blocked vs. interleaved presentation and proactive interference in episodic memory

Although a number of theoretical accounts of proactive interference (PI) in episodic memory have been proposed, existing empirical evidence does not support conclusively a single view yet. In two experiments we tested the predictions of the temporal discrimination theory of PI against alternative accounts by manipulating the presentation schedule of study materials (lists blocked by category vs. interleaved). In line with the temporal discrimination theory, we observed a clear buildup of (and release from) PI in the blocked condition, in which all the lists of the same category were presented sequentially. In the interleaved condition, with alternating lists of different categories, a more gradual and smoother buildup of PI was observed. When participants were left free to choose their presentation schedule, they spontaneously adopted an interleaved schedule, resulting again in more gradual PI. After longer delays, we observed recency effects at the list level in overall recall and, in the blocked condition, PI-related effects. The overall pattern of findings agrees with the predictions of the temporal discrimination theory of PI, complemented with categorical processing of list items, but not with alternative accounts, shedding light on the dynamics and underpinnings of PI under diverse presentation schedules and over different time scales.     

Unconscious Semantic Priming Influences Performance of Visuomotor Tasks Differently but the Effects are Similar in Young and Older Adults

We examined the effects of semantic priming of attention on two sequentially presented visuomotor tasks, traffic judgments and saccadic adaptation. Priming was accomplished with the scrambled sentence task: participants formed meaningful sentences from a list of words where a word denoting wide attention focus was involved. The results showed that semantic priming influenced positively saccade adaptation (its’ benefit increased) while it attenuated visuomotor performance in the traffic task (RT of hand movements increased). We found the effects of priming on both tasks’ performance to be comparable in young and older participants. It was suggested that semantic priming effect on visuomotor tasks depended on the cognitive resources which were needful as for the priming as for the primed task.     

Are Persons Low in Self-Control Rational and Deterrable?

This work addresses a question raised by Wright et al. (2004 Wright , Richard T. and Scott H. Decker. 1994 . Burglars on the Job: Street life and Residential Breakins . Boston : Northeastern University Press . [Google Scholar]) pertaining to the rationality and deterrability of individuals with low self-control. According to some, all persons are presumed to be equally rational; according others, individuals who possess little self-control, who are impulsive and present-oriented are less likely to be influenced by a perceived risks and costs of punishment; and according to a third group of scholars, those who do possess such self-control/restraint are either not motivated toward offending or are inhibited by moral constraints and are, thus, unresponsive to sanction threats. These rival predictions are examined with the use of self-report survey data on academic dishonesty from a sample of undergraduate college students. Across a tremendous number of models employing a variety of functional forms for the effects of perceived sanction threats, we consistently observed that the effects of perceived sanction threats on college students' self-reported academic dishonesty did not vary by their level of offending propensity (self-control).     

NOTES ON CONTRIBUTORS

Louis L'Amour is one of the most prolific and popular writers of our time. He has published more than 85 novels, many of which have been made into movies for theatres or television. His first novel, Hondo, was published in 1953 and his latest in 1984, The Walking Drum.

Mr. L'Amour's interest and dedication to education, in the classical sense, is liberally evidenced through the characters of his novels. Beginning in his early books with characters who lamented the fact that they were uneducated or self-educated and growing toward the latest novel that has a genuine scholar as the main character. His latest book is not a western but takes place in medieval Europe.

It may be of value to introduce pre-adolescents and adolescents to Mr. L'Amour's works in the public school libraries. It may do more than introduce them to a gifted, action and adventure, storyteller. It could help to improve reading skills with the added possibility that they may become interested in some of the classical literature given reference in his novels. Another possibility is that they may be persuaded of the value of an education through the many references the subject in the novels.     

Working Memory Control Deficit in Kindergarten ADHD Children

The present study tests the hypothesis that a working memory deficit is also found in children with attention deficit/hyperactivity disorder (ADHD) symptoms as young as 5 and is related to the control of interfering information. One group of 23 kindergarten children identified by the presence of ADHD symptoms and one group of 23 children matched for gender, age, and socioeconomic status were administered a visuospatial working memory task that required the selective recall of information. Children with ADHD symptoms performed more poorly than controls and were affected to a particularly high extent by intrusion errors (i.e., recalling of information initially encoded but that needed to be consequently suppressed during the task).     

Escaping from Rama: Portraits of Indian women

This study examines visual, post-colonial portraits of the Indian women of the Sanskrit epics, in order to show the sociocultural, historical-ideological roots of this aesthetic. After independence, Hindu movements found in the epics a female archetype, who stands for the Hindu community. Post-colonial visual representations maintained this idealistic characterisation within a binary system, according to which women can be angelic guarantors of the social order or devilish, sexually uncontrolled creatures. This ambiguity derives from the double nature of the female principle of the world, shakti, and the visual storytelling tradition or chitrakatha. Using the same Indian storytelling tradition, female points of view have begun to criticise this nationalistic, ‘male gaze’. In the graphic novel Sita's Ramayana, Rama and male activities, particularly war, are secularised and criticised as selfish by female characters, foremost of whom is Sita, a model of the devoted and pure bride or pativrata.
