Preschool boys' development of emotional self-regulation strategies in a sample at risk for behavior problems

Little longitudinal research has been conducted on changes in children's emotional self-regulation strategy (SRS) use after infancy, particularly for children at risk. In this study, the authors examined changes in boys' emotional SRS from toddlerhood through preschool. Repeated observational assessments using delay of gratification tasks at ages 2, 3, and 4 years were examined with both variable- and person-oriented analyses in a low-income sample of boys (N = 117) at risk for early problem behavior. Results were consistent with theory on emotional SRS development in young children. Children initially used more emotion-focused SRS (e.g., comfort seeking) and transitioned to greater use of planful SRS (e.g., distraction) by 4 years of age. Person-oriented analysis using trajectory analysis found similar patterns from 2 to 4 years, with small groups of boys showing delayed movement away from emotion-focused strategies or delay in the onset of regular use of distraction. The results provide a foundation for future researchers to examine the development of SRS in low-income young children.     

Reflections on <Emphasis Type="Italic">reflective knowledge</Emphasis>

In his volume reflective knowledge, Ernest Sosa offers an account of knowledge, an argument against internalist foundationalism, and a solution to the problem of easy knowledge. This paper offers challenges to Sosa on each of those three things.     

Engagement in a Science Museum – The Role of Social Interactions

This qualitative research explores the interactions of elementary school students during free-choice activity with science museum exhibits. The study participants were 39 students, who visited a science museum on six occasions during a three-year-period (from 4^th to 6^th grades). Our study showed that most interactions around exhibits are social in nature. Within these social interactions, students mainly discuss the technicalities of operating the exhibits and rarely engage with their scientific content. On occasion, exhibits are no more than settings for social interactions that could equally occur, for example, in the schoolyard. The main implications of this study concern exhibit design and pedagogy. Because students find ways to create their own social interactions in museum settings, museum pedagogy should leverage this social interaction into cognitive engagement with the scientific content of exhibits.     

Immunization of opioid analgesia: Effects of prior escapable shock on subsequent shock-induced and morphine-induced antinociception

In Experiment 1, it was shown that experience with escapable foot shock 4 hr prior to a session of 80 inescapable tail shocks prevented the occurrence of an analgesic response normally observed immediately following the tail shock. It has been suggested by J. W. Grau, R. L. Hyson, S. F. Maier, J. Madden, and J. D. Barchas (Science, 1981, 213, 1409–1411) that the analgesia that occurs following this number of inescapable tail shocks is mediated by endogenous opioid systems. To further explore the influence of escapable shock on opiate-mediated analgesia, Experiment 2 examined the effects of prior escapable shock on the long-term analgesia reaction that occurs upon brief exposure to shock 20 hr after morphine administration. Rats were given escapable shock, inescapable shock, or no shock 4 hr prior to a morphine injection. Twenty hours following the injection, all subjects received 5 brief foot shocks and were then immediately given tail-flick analgesia tests. Subjects which received inescapable shock or no shock prior to the morphine injection displayed a significant analgesic response. However, subjects which received escapable shock prior to morphine were not analgesic following brief exposure to shock. Thus, escapable shock seems to directly influence the activation of opioid analgesia systems.     

It’s a matter of time (perspectives): shifting valence responses to emotional ambiguity

Our stage in life has profound influences on our emotions. A well-established age-related positivity effect is putatively related to time perspectives—older adults have a limited time perspective and a greater motivation to experience positivity than young adults. Ambiguous emotions (e.g., surprised expressions) have both a positive and negative meaning, offering a highly relevant model for examining this developmental trend. Indeed, there are stable, trait-like individual differences in valence bias, or the tendency to interpret surprise as positive or negative, with a developmental trend toward positivity (older adults are more positive than young adults, who are more positive than children). However, little research has determined the extent to which the bias can be shifted. In three experiments, we found that ambiguity ratings were sensitive to time perspectives, even within a population of college students, and that this effect is relatively long-lasting. Results extend socioemotional selectivity theory and demonstrate that our life stage may have profound effects on otherwise stable emotional responses.     

Humans prefer curved visual objects

People constantly make snap judgments about objects encountered in the environment. Such rapid judgments must be based on the physical properties of the targets, but the nature of these properties is yet unknown. We hypothesized that sharp transitions in contour might convey a sense of threat, and therefore trigger a negative bias. Our results were consistent with this hypothesis. The type of contour a visual object possesses--whether the contour is sharp angled or curved--has a critical influence on people's attitude toward that object.     

Very first impressions

First impressions of people's personalities are often formed by using the visual appearance of their faces. Defining how quickly these impressions can be formed has critical implications for understanding social interactions and for determining the visual properties used to shape them. To study impression formation independent of emotional cues, threat judgments were made on faces with a neutral expression. Consequently, participants' judgments pertained to the personality rather than to a certain temporary emotional state (e.g., anger). The results demonstrate that consistent first impressions can be formed very quickly, based on whatever information is available within the first 39 ms. First impressions were less consistent under these conditions when the judgments were about intelligence, suggesting that survival-related traits are judged more quickly. The authors propose that low spatial frequencies mediate this swift formation of threat judgments and provide evidence that supports this hypothesis.
