Personality traits and self-presentation at Facebook

The current study explores the relationship between personality traits and self-presentation at Facebook. An online survey of Facebook users was conducted. The results suggest that extraversion was positively related to self-presentation both on Wall and at News Feed. Extraverts uploaded photos and updated status more frequently, and had more friends displayed on Wall than introverts. Besides, extraverts clicked Like, wrote Comment and clicked Share at News Feed more frequently than introverts. Moreover, narcissists with high rivalry frequently updated their Status on Wall. In addition, neuroticism and conscientiousness were negatively related to writing Comment at News Feed. Lastly, openness to experience was negatively related to clicking Share at News Feed. The results and implications are discussed in conjunction with previous research. Suggestions for future research are provided.     

The ghost of Christmas future: didn't Scrooge learn to be good? Commentary on Magnuson,McMurray, Tanenhaus,and Aslin (2003)

Magnuson, McMurray, Tanenhaus, and Aslin [Cogn. Sci. 27 (2003) 285] suggest that they have evidence of lexical feedback in speech perception, and that this evidence thus challenges the purely feedforward Merge model [Behav. Brain Sci. 23 (2000) 299]. This evidence is open to an alternative explanation, however, one which preserves the assumption in Merge that there is no lexical–prelexical feedback during on‐line speech processing. This explanation invokes the distinction between perceptual processing that occurs in the short term, as an utterance is heard, and processing that occurs over the longer term, for perceptual learning.     

The Mysterious Silence of Mother Earth in Laudato Si'

Laudato si' attempts simultaneously to disrupt prevailing global environmental discourse and to reorient central concepts in Catholic moral tradition by requalifying the meaning of dominion and by ecologically expanding human dignity. The image of Earth crying out to humans from within a kinship relation plays a central role in both arguments. However, the political consequences of those shifts remain vague because the “voice” of Earth remains silent in crucial loci of the encyclical's argument.     

Social-relational exposures and well-being: Using multivariate twin data to rule-out heritable and shared environmental confounds

The aims of the present study were as follows: (1) Using a large sample of adults, estimate overlap between social-relational exposures measured at midlife and well-being measured at midlife and approximately 9-years later. (2) Using a subsample of twins, test for heritable variation in social-relational exposures, and (3) controlling for heritable and shared environmental variation, estimate overlap between social-relational exposures and well-being, both concurrently and approximately 9-years later. Results indicated small-to-moderate overlap between exposures and well-being (mean r = 0.29, range = 0.05–0.54). There was also evidence for heritable variation in exposures, and after accounting for these genetic factors, the degree of overlap between social-relational exposures and well-being decreased (mean r = 0.10, range = −0.07 to 0.33).     

Growing Together—Effects of a school-based intervention promoting positive self-beliefs and social integration in recently immigrated children

We present a school-based intervention geared to foster the social integration of recently immigrated (RI) primary school children by creating repeated positive contact situations with classmates brought up in the receiving society. Coaches encouraged groups of tandems, consisting of one RI and one child brought up in Germany each, to engage in cooperative activities designed to strengthen positive self-beliefs and perception of equal status. In a quasi-experimental control-group design (N = 318), we compared the 30 children (12 RI) who participated in our intervention between pre-test and post-test with a reference group. Self-beliefs were measured via self-reports, social integration via sociometric peer-nominations. The reference group (n = 288 children) included all children who did not participate in the intervention between pre-test and post-test: (a) 12 children (7 RI) of a waiting control group and (b) all classmates of both the students of the intervention and the waiting control group. Post-test self-beliefs were more positive in children having participated in the intervention. The intervention did not affect social integration: Neither the number of classmates nominating a student nor the number of peers the respective student nominated increased. Possibly, the intervention initiated self-reinforcing processes which support social integration over longer time periods.     

A social-cognitive framework for understanding serious lies: Activation-decision-construction-action theory

Little is known about the cognition of deception (Gombos, 2006). We propose a cognitive account of serious lying (i.e., deception involving high stakes) in response to a solicitation of a truth: Activation-Decision-Construction-Action Theory (ADCAT). Built on the Activation-Decision-Construction Model of answering questions deceptively (Walczyk, Roper, Seeman, & Humphrey, 2003), the theory elaborates on the roles of executive processes, theory of mind, emotions, motivation, specifies cognitive processing thoroughly, and considers the rehearsal of lies. ADCAT's four processing components are (a) activation of the truth, the (b) decision whether and how to alter deceptively the information shared, (c) construction of a deception, and (d) action [acting sincere while delivering a lie]. Core constructs are “theory of mind” and “cognitive resources”. Specifically, throughout serious deception, individuals are inferring the current or potential mental states of targets and taking steps to minimize the allocation of cognitive resources during delivery to appear honest and lie well.     

Empathy framework for embodied conversational agents

Empathy is a complex socio-emotional behavior that results from the interaction between affective and cognitive mechanisms. Equipping embodied conversational agents (ECAs) with empathic capacity can benefit from the integration and evaluation of these low and high level capabilities in a hierarchical manner. Following the theoretical background on empathic behavior in humans, this paper presents a framework to equip ECAs with real time multi-modal empathic interaction capabilities. We present the implementation of this framework, which includes basic dialogue capabilities as well as three levels of empathic behavior in a conversational scenario. Our approach is an inclusive stand on modeling levels of empathy and provides a baseline behavior for empathic interaction.     

Racial bias in behavioral assessment of children's social skills

The social skills of 20 second- and sixth-grade students were assessed by 20 trained raters using the Social Skills Test for Children (SST-C). Rater and child characteristics were examined to determine whether differences in social skills ratings were due to the race of the rater or the race of the children being rated or due to the interactive effects of these characteristics, which would suggest racial bias in the ratings procedure. The results showed that the race of the rater did affect some behavioral observations. Black raters gave higher scores than white raters on four behavioral categories: response latency, appropriate assertion, effective assertion, and smiling. White raters gave higher scores for head position and gestures. The results of this study replicated earlier findings of significant differences in social skills ratings due to the race and age of the child being rated. The results also showed modest racial bias effects in that black and white raters scored black and white children differentially on two behavioral categories: overall skill ratings and smiling. These results suggested that most behavioral categories of the SST-C were not systematically affected by racial bias. However, the most subjective rating, overall skill, did evidence racial bias effects. This finding is consistent with previous data showing that subjective ratings may be most affected by racial bias.     

Critical thinking in North America: A new theory of knowledge,learning, and literacy

The pace of change in the world is accelerating, yet educational institutions have not kept pace. Indeed, schools have historically been the most static of social institutions, uncritically passing down from generation to generation outmoded didactic, lecture-and-drill-based, models of instruction. Predictable results follow. Students, on the whole, do not learn how to work by, or think for, themselves. They do not learn how to gather, analyze, synthesize and assess information. They do not learn how to analyze the diverse logic of the questions and problems they face and hence how to adjust their thinking to those problems. They do not learn how to enter sympathetically into the thinking of others, nor how to deal rationally with conflicting points of view. They do not learn to become critical readers, writers, speakers and listeners. They do not learn how to use their native languages clearly, precisely, or persuasively. They do not, therefore, become literate, in the proper sense of the word. Neither do they gain much in the way of genuine knowledge since, for the most part, they could not explain the basis for what they believe. They would be hard pressed to explain, for example, which of their beliefs were based on rational assent and which on simple conformity to what they have been told. They have little sense as to how they might critically analyze their own experience, or identify national or group bias in their own thinking. They are much more apt to learn on the basis of irrational than rational modes of thought. They lack the traits of mind of a genuinely educated person: intellectual humility, courage, integrity, perseverance, and faith in reason.Happily, there is a movement in education today striving to address these problems in a global way, with strategies and materials for the modification of instruction at all levels of education. At its foundation is an emerging new theory of knowledge, learning, and literacy, one which recognizes the centrality of independent critical thinking to all substantial learning, one which recognizes that higher-order, multilogical thinking is as important to childhood as to adult learning, and as important to foundational learning in monological as in multilogical disciplines. This educational reform movement is not proposing an educational miracle cure, for its leading proponents recognize that many social and historical forces must come together before the ideals of the critical thinking movement will become a full academic reality. Schools do not exist in a social vacuum. To the extent that the broader society is uncritical so, on the whole, will be society's schools. Nevertheless, the social conditions necessary for fundamental changes in schooling are increasingly apparent. The pressure for fundamental change is growing. Whether and to what extent these needed basic changes will be delayed or side-tracked, thus requiring new periodic resurgences of this movement, with new, more elaborate articulations of its ideals, goals, and methods — only time will tell.     

Spectral factors in the perception of vowel quantity in Icelandic

Previous research has shown that the ratio of vowel to rhyme (vowel + consonant) duration is a major cue for quantity in Icelandic. In particular it serves as a higher-order invariant which enables the listener to disentangle those durational transformations of the speech signal which are "extrinsic" (e. g. due to changes in speaking rate) from those which are "intrinsic" to the phonemic message, involving a change of phonemic quantity. Previous research has been based on speech segment contrasts which are purely durational, involving vowels with a uniform spectrum whether phonemically long or short, such as [a] or [I]. This paper looks at the role of spectral factors in vowels which are spectrally dissimilar in their long and short varieties. It is shown that in these cases the spectral differences can be sufficiently great to override the previously established relational invariant for quantity. The implications of this finding for a model of quantity perception are discussed.
