“I'm an ogre so I'm very hungry!” “I'm assistant ogre”: The Social Function of Sibling Imitation in Early Childhood

Siblings' imitative behaviors were investigated in 39 middle‐class dyads during six 90‐min home sessions at both Time 1 (M age: older sibling = 4.4 years; younger sibling = 2.4 years) and Time 2 (2 years later). Although younger siblings imitated most often at T1 and T2, older siblings' imitation increased proportionally over time in comparison to younger siblings. Findings highlight the affiliative nature of imitation that occurred during reciprocal play interactions, via positive responses, and the content of the imitation. Finally, age was controlled by comparing first‐born siblings aged 4 at T1 to second‐born siblings aged 4 at T2. Findings demonstrated that sibling imitation had distinct characteristics despite the age match and partner effects. Sibling imitation is a dynamic, interactive social behavior and may be a powerful source of learning for young children.

Highlights

• The role of sibling imitation in ongoing play in early childhood is highlighted.
• Sibling imitation is a dynamic and affiliative behavior that promotes interaction during play.
• Naturalistic observations of sibling imitation document that it is a powerful source of learning for young children.

     

Age Differences in Processes Underlying Hindsight Bias: A Life-Span Study

Hindsight bias is the tendency to overestimate one’s prior knowledge of a fact or event after learning the actual fact. Recent research has suggested that age-related differences in hindsight bias may be based on age-related differences in inhibitory control. We tested whether this explanation held for 3 cognitive processes assumed to underlie hindsight bias: recollection bias, reconstruction bias, and the tendency to adopt newly acquired knowledge as old. We performed a typical hindsight-bias study with 9-year-olds, 12-year-olds, young adults, and older adults. Participants first gave numerical judgments to difficult almanac questions. They later received the correct judgments for some of the questions while trying to recall their own earlier judgments. To experimentally test the impact of inhibitory control, the correct judgment was presented either in a weak or in a strong manner that was difficult to ignore. Hindsight bias was larger in the strong condition than in the weak condition and followed a U-shaped life-span pattern with young adults showing the least hindsight bias in line with an inhibitory-control explanation. Yet, the mixture of underlying processes differed considerably between age groups, so inhibitory control did not suffice as a sole explanation of age differences.     

Differential influence of basic psychological needs on burnout and academic achievement in three southeast European countries

Several studies show the importance of basic psychological needs (BPN) for decreasing burnout and increasing grade point average (GPA), but, to our knowledge, no prior study has explored the potential contextual differences in Southeastern European countries. Moreover, even less is known about how this relationship may differ during stressful (exam) and less stressful (beginning of the semester) periods. Measures of the Maslach Burnout Inventory—Student Survey and BPN Satisfaction and Frustration Scale were translated and adapted. The study included a cross-sectional sample of students from Croatia, Serbia and Slovenia during beginning of the semester and exam period. Across all countries and both contexts, students with high autonomy need satisfaction showed the strongest decrease in burnout, followed by those with high competence need satisfaction. Students with high academic achievement showed an increase due to competence need satisfaction. Competence and autonomy need satisfaction were higher beginning of a semester, while burnout was higher during the exam period. BPN play an important role in educational settings—satisfaction of the need for autonomy and competence protects students from burnout, and the need for competence predicts greater academic achievement regardless of culture or time of the semester.     

词频、可预测性及合理性对目标词首次注视位置的影响

采用三项实验分别考察了目标词的词频、可预测性和合理性对读者眼动模式的影响。结果显示:(1)词频、可预测性和合理性对目标词语的凝视时间和总注视时间都有显著影响,但在首次注视时间上主效应不显著;(2)词频和可预测性不影响目标词的跳读率和再注视概率,而合理性对目标词的再注视概率产生显著的影响;(3)远注视点眼跳倾向于将首次注视位置着落于目标词的开端部位,而近注视点眼跳倾向于将首次注视着落于目标词的中央部位;词频、可预测性和合理性均不影响首次注视位置。     

Social comparison 2.0: examining the effects of online profiles on social-networking sites

Through their features--such as profile photographs or the personal vita--online profiles on social-networking sites offer a perfect basis for social comparison processes. By looking at the profile photograph, the user gains an impression of a person's physical attractiveness, and the user's vita shows which career path the person is pursuing. Against the background of Festinger's Social Comparison Theory, the focus of this research is on the effects of online profiles on their recipients. Therefore, qualitative interviews (N?=?12) and two online experiments were conducted in which virtual online profiles of either physically attractive or unattractive persons (N?=?93) and profiles of users with either high or low occupational attainment (N?=?103) were presented to the participants. Although qualitative interviews did not initially give reason to expect online profiles to constitute a basis for comparison processes, results of the experiments proved otherwise. The first study indicates that recipients have a more negative body image after looking at beautiful users than persons who were shown the less attractive profile pictures. Male participants of the second study, who were confronted with profiles of successful males, showed a higher perceived discrepancy between their current career status and an ideal vita than male participants who looked at profiles of less successful persons.     

Aphasic patients exhibit a reversal of hemispheric asymmetries in categorical color discrimination

Patients with left hemisphere (LH) or right hemisphere (RH) brain injury due to stroke were tested on a speeded, color discrimination task in which two factors were manipulated: (1) the categorical relationship between the target and the distracters and (2) the visual field in which the target was presented. Similar to controls, the RH patients were faster in detecting targets in the right visual field when the target and distracters had different color names compared to when their names were the same. This effect was absent in the LH patients, consistent with the hypothesis that injury to the left hemisphere handicaps the automatic activation of lexical codes. Moreover, the LH patients showed a reversed effect, such that the advantage of different target-distracter names was now evident for targets in the left visual field. This reversal may suggest a reorganization of the color lexicon in the right hemisphere following left hemisphere brain injury and/or the unmasking of a heightened right hemisphere sensitivity to color categories.     

Semantic dementia and persisting Wernicke's aphasia: linguistic and anatomical profiles

Few studies have directly compared the clinical and anatomical characteristics of patients with progressive aphasia to those of patients with aphasia caused by stroke. In the current study we examined fluent forms of aphasia in these two groups, specifically semantic dementia (SD) and persisting Wernicke’s aphasia (WA) due to stroke. We compared 10 patients with SD to 10 age- and education-matched patients with WA in three language domains: language comprehension (single words and sentences), spontaneous speech and visual semantics. Neuroanatomical involvement was analyzed using disease-specific image analysis techniques: voxel-based morphometry (VBM) for patients with SD and overlays of lesion digitized lesion reconstructions in patients with WA. Patients with SD and WA were both impaired on tasks that involved visual semantics, but patients with SD were less impaired in spontaneous speech and sentence comprehension. The anatomical findings showed that different regions were most affected in the two disorders: the left anterior temporal lobe in SD and the left posterior middle temporal gyrus in chronic WA. This study highlights that the two syndromes classically associated with language comprehension deficits in aphasia due to stroke and neurodegenerative disease are clinically distinct, most likely due to distinct distributions of damage in the temporal lobe.     

Effect of early intervention on social interaction between mothers and preterm infants at 12 months of age: a randomized controlled trial

In a randomized controlled trial at 12-months of age, the effect of the Mother Infant Transaction Program was tested on social interaction between mothers and moderately and late preterm infants with gestational age ≥ 30.0 and <36 weeks. Ninety-three play sessions were videotaped and coded, 46 mothers-infants in the intervention group and 47 mothers-infants in the control group. The intervention mothers scored higher on maternal sensitivity/responsiveness (p = .05). Being a first-time mother was a moderator that enhanced the effects of the intervention. First-time mothers were more sensitive/responsive to their infant's cues (p = .01), and the dyads evinced higher level of synchrony (p = .02) as compared with experienced mothers. More positive mood was observed among their infants (p = .04). The findings suggest that the intervention contributes to better mother-infant interactions in moderately and late preterm infants of first-time mothers.     

On turning a blind eye and a deaf ear: society's response to the use of torture

The present paper undertakes an individual and group psychoanalytic examination of what happens to the citizens of a society that not only condones but authorizes torture. Drawing on the experiences of countries like those in Latin America during the period of the military dictatorships of the 1970s and 1980s, South Africa during the apartheid years, the Nazi era in Germany in the 1930s and 1940s, and Eastern Europe in the Communist era, the author focuses on the denial that was necessary to maintain daily life. At the same time, such denial and its accompanying "compartmentalization" produced a citizenry that was both blind and deaf to the practices and ultimately supported the dangerous hypocrisy of the respective political regimes. The impact of such "blindness" and "deafness" to the use of torture and abrogation of basic civil rights on the psychological life of individuals and society is examined for its parallels to our current times within the United States.     

Evaluating the generalizability of a fear deficit in psychopathic African American offenders

Laboratory studies of psychopathy have yielded an impressive array of etiologically relevant findings. To date, however, attempts to demonstrate the generalizability of these findings to African American psychopathic offenders have been largely unsuccessful. The fear deficit has long been regarded as the hallmark of psychopathy, yet the generalizability of this association to African American offenders has not been systematically evaluated. In this study, we used an instructed fear paradigm and fear-potentiated startle to assess this deficit and the factors that moderate its expression in African American offenders. Furthermore, we conceptualized psychopathy using both a unitary and a two-factor model, and we assessed the constructs with both interview-based and self-report measures. Regardless of assessment strategy, results provided no evidence that psychopathy relates to fear deficits in African American offenders. Further research is needed to clarify whether the emotion deficits associated with psychopathy in European American offenders are applicable to African American offenders.
