Amygdala response to mother

In altricial species, like the human, the caregiver, very often the mother, is one of the most potent stimuli during development. The distinction between mothers and other adults is learned early in life and results in numerous behaviors in the child, most notably mother-approach and stranger wariness. The current study examined the influence of the maternal stimulus on amygdala activity and related circuitry in 25 developing children (n = 13) and adolescents (n = 12), and how this circuitry was associated with attachment-related behaviors. Results indicated that maternal stimuli were especially effective in recruiting activity in the left dorsal amygdala, and activity in this amygdala region showed increased functional connectivity with evaluative and motor regions during viewing of maternal stimuli. Increases in this left dorsal amygdala activity and related amygdala-cortical functional connectivity were associated with increased mother-approach behaviors as measured by in-scanner behavioral responding and out-of-scanner child-report. Moreover, age-related changes in amygdala activity to strangers statistically mediated the developmentally typical decline in stranger wariness seen across this period. These results suggest that mother-induced behaviors are enacted by maternal influence on amygdala-cortical circuitry during childhood and adolescence.     

Fragile visual short-term memory is an object-based and location-specific store

Fragile visual short-term memory (FM) is a recently discovered form of visual short-term memory. Evidence suggests that it provides rich and high-capacity storage, like iconic memory, yet it exists, without interference, almost as long as visual working memory. In the present study, we sought to unveil the functional underpinnings of this memory storage. We found that FM is only completely erased when the new visual scene appears at the same location and consists of the same objects as the to-be-recalled information. This result has two important implications: First, it shows that FM is an object- and location-specific store, and second, it suggests that FM might be used in everyday life when the presentation of visual information is appropriately designed.     

Feature-based inhibition underlies the affective consequences of attention

Rapid selection of a target in the presence of similar distractors can cause subsequent affective evaluation of a distractor to be more negative than that for the selected object. This distractor devaluation effect has previously been attributed to an association of attentional inhibition with the distractor's representation. Here, we investigated whether the associated inhibition leading to distractor devaluation is object based or feature based. Using colour-tinted face and building stimuli in a two-item simple visual search, followed by evaluation of face stimuli on a trustworthiness scale, we report that emotional evaluation was modified by prior attention whenever the search stimuli and the to-be-evaluated face shared the distractor feature, regardless of whether face identity seen in the two successive tasks matched or not. These data support the notion that inhibition can be feature-based and show that such inhibition can have emotional consequences.     

DOUBLE-VOICE IN S. Y. AGNON'S “HANIDAḤ”: OVERTURES TO A DEVELOPING DISCOURSE

It is widely acknowledged that S.Y. Agnon's story, “Hanida?” (1919), represents a significant artistic transition for the author. Beyond the transitional and inaugural aspects of the story's themes and structure, I wish to consider how its discursive style itself constitutes a significant development in Agnon's literary work. Particular qualities in the story's narrative discourse, more so than in his previous work, anticipate Agnon's later literary achievements. Drawing on Mikhail Bakhtin's theory of discourse in the novel, I will also seek to demonstrate how the story's dialogic, polyphonic qualities, not only anticipate these later works, but suggest some new hermeneutic avenues to reading Agnon.     

The Integration of Determinants and Content in Rorschach Interpretation

Millon has presented a grand and rich theory of personality disorder. Fundamental to this theory are three polarity dimensions (active-passive, pleasure-pain, and self-other) from which the personality disorders are said to be derived. This article reviews these polarity dimensions with respect to their conceptual relation with the personality disorder nomenclature, their assessment, and their empirical support.     

The Messiah and Rabbi Jesus: Policing the Jewish–Christian border in Christian Zionism

For all their ostensible difference and separateness, Judaism and Christianity have a long history of mutual engagement and profound entanglement. I take Daniel Boyarin's assertion that ‘…the borders between Christianity and Judaism are as constructed and imposed, as artificial and political as any of the borders of the earth’ (2004, 1) as my starting point. But what Boyarin sees as an ongoing process of differentiation between Judaism and Christianity and distinct identity-building in late antiquity, I look for still today in Christian Zionism. The busy border crossing continues to separate people and ideas at the same time as it serves as the meeting place between them, the uncomfortable place where Judaism and Christianity rub up against each other. This paper examines some constructions of the Jewish–Christian border by way of two case studies of prominent religious leaders, each firmly at home in their respective communities, Jewish and Christian, who ventured out to the borderland of Christian Zionism. This is the story of what happened when they returned home to find themselves examined by those who monitor the Jewish–Christian border, and deemed to be over the limit with intoxicants brought over from the ‘other side’.     

Causal Attribution and Perceived Realism of Stories

Just as people generate causal explanations for social events around them, story readers usually generate inferences about causality of events when reading a story. The attribution literature suggests that, when judging events that happen to others, people spontaneously generate dispositional explanations for negative events and situational explanations for positive events and the reverse when judging events that happen to themselves. Three experiments examined how these spontaneously generated inferences of causality interacted with causal explanations provided by the text of a story to influence perceived realism. The results indicate that the relationship between spontaneously generated causal attributions and information supplied by the story had little influence on realism judgments about story characters or about other people. When evaluating the story scenario for the self, however, results of all three experiments show that people find information consistent with their own spontaneous attributions more realistic. The results contribute to our understanding of the psychological processes that may drive realism evaluations of stories and possible contrasting mechanisms between attributions in story worlds and the social world.     

In the Same Ballpark or a Whole New Ball Game? Staff as Raters of Youth Behavior

There is a lack of psychometrically sound tools for measuring youth outcomes in out-of-school time (OST) settings. Consequently, behavior ratings completed by OST staff are being scored as though the raters were teachers, even though cross-informant correlations are notoriously low (meta-analysis r?=?.27). Across 26 schools, 227 students were assessed by both teachers and OST staff using the Devereux Student Strengths Assessment (DESSA) to measure Social Emotional Competence. These 4th and 5th grade students were 50% male; 53% 5th graders; and 51% Latino, 20% Mixed/Other, 11% Black, 11% Asian, and 7% White. In the full sample, OST staff rated children’s behavior more harshly than teachers (p?<?.001; d?=?.32), although the scores were associated (r?=?.31, p?<?.001). Among the ratings completed within the same week, teacher and staff distributions were not statistically different. Teacher and staff ratings had a “medium” correlation (r?=?.42; p?=?.01) and a classification consistency (88%) that exceeded chance by a “moderate” amount (κ?=?.43). Few, if any, studies have previously compared the ratings of the same children by teachers and OST providers. Cross-informant inter-rater reliability between teachers and OST staff was higher than expected on the DESSA.     

Alpha,beta: The rhythm of the attentional blink

Extant theories of the attentional blink propose that the most critical factor in determining second target accuracy is the time that elapses between the first and second targets. We report that this conclusion has overlooked an equally important determinant, namely, the frequency of the entraining stream in which these targets are embedded. Specifically, we show in two experiments that the signature of the attentional blink—second target accuracy that increases with intertarget lag—is significantly larger for entraining streams that are in the alpha-beta frequency range, relative to streams that are slower (theta) or faster (gamma). This finding ties the attentional blink critically, for the first time, to these two prominent oscillation frequencies that are known to be involved in the control of human attention and consciousness.     

The company you keep: Fear of rejection in intergroup interaction

People use many cues to infer the likelihood of acceptance or rejection in intergroup interactions. Nearly all prior research has focused on personal cues directly given off by the potential interaction partner (e.g., eye contact and smiling). However, we argue that in the context of intergroup interactions, individuals may be especially sensitive to broader social cues, such as an interaction partner's social network. Across three experiments we explored differences in White participants' evaluations of a smiling Black man presented with a Black or White friend. When this Black man was featured with a Black friend, White participants reported greater rejection concerns and a greater inclination to reject this Black man compared to when he was featured with a White friend (Experiments 1-3) or featured alone (Experiment 2). Furthermore, when participants received a simple intervention designed to buffer against social rejection, the race of the Black man's friend no longer influenced participants' interests in befriending the Black man (Experiment 3). This research demonstrates the power of friendships in interracial interactions and provides evidence for a simple intervention to reduce the weight of rejection concerns in interracial interactions.
