Relational factors of vulnerability and protection for adolescent pregnancy: a cross-sectional comparative study of Portuguese pregnant and nonpregnant adolescents of low socioeconomic status

This study explores multiple relational contexts that promote vulnerability and protection against early pregnancy in a potential risk group of Portuguese adolescents. A comparative analysis was made between two groups of female adolescents of low socioeconomic status: pregnant adolescents (n=57) and adolescents without a history of pregnancy (n=81). Results suggest that several variables belonging to different contexts-family and school and peer relations--are important in the characterization of the two groups. Lower levels of mother's overprotection and father's emotional support, presence of early pregnancy in adolescent's mother, lower level of emotional proximity to peer relations, and higher number of school failures are significantly associated with adolescent pregnancy.     

Consequential conditionals: invited and suppressed inferences from valued outcomes

Consequential conditionals are defined as "if P then Q" statements, where P is an action, and Q a predicted outcome of this action, which is either desirable or undesirable to the agent. Experiment 1 shows that desirable (viz. undesirable) outcomes invite an inference to the truth (viz. falsity) of their antecedent. Experiment 2 shows that the more extreme the outcome is, the stronger the invited inference is. Experiment 3 shows that modus ponens from premises "If A then C, A" can be suppressed with the introduction of a consequential conditional, "If C then Q," where Q is an undesirable outcome. Experiment 4 shows that the more undesirable Q is, the larger the suppression is. The authors discuss how these results can enrich current approaches of conditional inference on the basis of mental models, complementary necessary conditions, and conditional probabilities.     

Dogs in Animal Shelters: Problems, Suggestions, and Needed Expertise

Because of very real practical constraints, conditions in animal shelters are often reminiscent of those in early primate deprivation studies. Dogs are frequently surrendered to shelters because of behavior problems, and aspects of the shelter environment may induce anomalous behavior, increasing the chances that adopted dogs will be returned to the shelters. Comparative psychologists, psychobiologists, and other behavioral scientists possess the knowledge and techniques to help shelters intervene in this cycle. Experience suggests human interaction and the application of basic conditioning procedures can reduce the impact of the shelter environment, and ease the transition into the adoptive home. A program developed to meet these goals is described. Shelters can provide opportunities both for the training of students in animal-related exercises and for limited applied research. Behavioral scientists stand in a unique position to help transform conditions in animal shelters to the benefit of all involved.     

Modulation of the palmar grasp behavior in neonates according to texture property

The study investigates the newborn's grasping behavior according to the texture property of an object. 22 full term healthy newborns were tested with their right hand. Eleven babies were exposed to a first condition in which the spontaneous manual activity on an object with a smooth texture was recorded. Eleven babies were exposed to an another condition: they hold the very same object than those presented in the baseline condition except that thin pearls were added on its surface, increasing its roughness. The results provide evidence for the existence of a modulation of hand activity according to the texture property of the object. The nature of this modulatory capacity of the hand is discussed.     

An automated technique for the study of cyclic fluctuations in sexual motivation in an avian species

Diurnal fluctuations in sexual behavior occur in freely interacting pairs of male and female birds. These fluctuations are difficult to interpret because they may reflect fluctuations in the motivation of the male, the motivation of the female, or both. A method was developed to study the sexual motivation of male Japanese quail in response to a standard stimulus. Sexual behavior was elicited by a taxidermic model of a female quail in a squatting posture. Sensors beneath and in the back of the model served to detect when the male mounted and made cloacal contact with the model. The technique allowed continuous recording of male sexual behavior under standard conditions. When males were maintained on a photoperiod with lights on at 0600 h and off at 2200 h, sexual behavior peaked in the early afternoon, with a secondary peak just before lights-out.     

Traumatization of group leaders in their work with displaced persons

Displaced persons are a special, threatened group of people, participants in this war, who were suddenly forced to abandon their homes. The majority of them were, overnight, left without anything they had, some even without their closest family. They all have one thing in common: they have all lost so much. Work with such people is directed toward overcoming their feelings of loss and abandonment and preventing psychical decompensation. Groups of displaced persons temporarily sheltered in the Rijeka region have been observed to be markedly regressed, with increased sensitivity, a low degree of tolerance, great demands on society and strongly expressed projective tendencies. Therapists suffer personal traumatization in working with displaced persons. This paper describes the reactions and feelings of group leaders caused by manifestations of group dynamics in different phases of exile.     

Attentional Abilities and Maternal Scaffolding in the First Year of Life

It is argued here that the development of attentional abilities during infancy does not rely exclusively on individual, stable characteristics of the child, but that interactions between infants and their social and physical environment play an important role in this development. In a longitudinal study at home, dyadic interactions and attentional behaviours were recorded at 5 and 8 months in 30 dyads. Two questions were relevant: How is focused attention part of infants' activities in their usual environment? How is the mother involved in this focused attention, and do maternal behaviours have effects on the infant? At around 5 months of age, a coherent set of results show that the mother plays a crucial role in the control of the infant's attention, which is still detectable three months later. The notion of attention scaffolding, which foreshadows subsequent scaffolding during problem solving, is discussed, as well as the indices evaluating attentional abilities.     

Stop Doubting with Descartes

Did Descartes manage to overcome the skeptics? If we understand “overcome” in the sense of “refute,” the answer is no, since his hyperbolic doubt harbors several blind spots and is, therefore, not as radical as is commonly argued. In this way, the victory of the cogito is perhaps less decisive and fruitful than it is claimed. If we understand “overcome” in the sense of “remove” or “move beyond,” the answer is yes. Descartes has overcome skepticism, but at the cost of a decision, a sort of bet made in favor of reason based on a confidence in the human mind that is never really subverted. This faith in reason, truth, and specific epistemological principles in Descartes’ philosophy constitute what Wittgenstein calls “hinges,” which are indispensable for doubting and searching for truth. In this sense, Descartes’ anti-skepticism is more a confidence in reason in order to save the possibility of science than the result of a logical refutation.

     

Should I invite them? Bystanders' inclusivity judgements towards outgroup victims and ingroup bullies in intergroup bullying

This study examined bystanders' judgements of bullying and their inclusivity towards refugee victims and ingroup bully peers. Participants included 587 Turkish adolescents (M_age = 13.14, SD = 1.60) who were presented with two stories: intergroup (Syrian refugee victim) and intragroup (Turkish victim) bullying. They indicated acceptability of bullying, retaliation, and how likely they would be to include victims and bullies in different social contexts. Empathy, prejudice, desired social distance, and peer norms towards Syrian refugees were examined as predictors. Adolescents in schools with a higher number of Syrian peers were more likely to expect they would include the Syrian victim than adolescents in schools with a lower number of Syrian peers. Further, adolescents with higher empathy were more likely to include the Syrian victim while adolescents with higher prejudice and desired social distance were less likely to include the Syrian victim. The results highlight the importance of attending to bystanders' future interactions with victims and bullies, as bystanders have the opportunity to challenge injustice by promoting inclusive school climates in diverse societies.
