Integration without awareness: expanding the limits of unconscious processing

Human conscious awareness is commonly seen as the climax of evolution. However, what function-if any-it serves in human behavior is still debated. One of the leading suggestions is that the cardinal function of conscious awareness is to integrate numerous inputs-including the multitude of features and objects in a complex scene-across different levels of analysis into a unified, coherent, and meaningful perceptual experience. Here we demonstrate, however, that integration of objects with their background scenes can be achieved without awareness of either. We used a binocular rivalry technique known as continuous flash suppression to induce perceptual suppression in a group of human observers. Complex scenes that included incongruent objects escaped perceptual suppression faster than normal scenes did. We conclude that visual awareness is not needed for object-background integration or for processing the likelihood of an object to appear within a given semantic context, but may be needed for dealing with novel situations.     

Association and dissociation between detection and discrimination of objects of expertise: Evidence from visual search

Expertise in face recognition is characterized by high proficiency in distinguishing between individual faces. However, faces also enjoy an advantage at the early stage of basic-level detection, as demonstrated by efficient visual search for faces among nonface objects. In the present study, we asked (1) whether the face advantage in detection is a unique signature of face expertise, or whether it generalizes to other objects of expertise, and (2) whether expertise in face detection is intrinsically linked to expertise in face individuation. We compared how groups with varying degrees of object and face expertise (typical adults, developmental prosopagnosics [DP], and car experts) search for objects within and outside their domains of expertise (faces, cars, airplanes, and butterflies) among a variable set of object distractors. Across all three groups, search efficiency (indexed by reaction time slopes) was higher for faces and airplanes than for cars and butterflies. Notably, the search slope for car targets was considerably shallower in the car experts than in nonexperts. Although the mean face slope was slightly steeper among the DPs than in the other two groups, most of the DPs’ search slopes were well within the normative range. This pattern of results suggests that expertise in object detection is indeed associated with expertise at the subordinate level, that it is not specific to faces, and that the two types of expertise are distinct facilities. We discuss the potential role of experience in bridging between low-level discriminative features and high-level naturalistic categories.

Paternal Support and Involvement in Unmarried Fragile Families: Impacts on Long-Term Maternal Mental Health

Fragile families are defined as those that include unmarried or romantically unstable parents who have children and are socioeconomically disadvantaged. Mothers in fragile families may experience risk factors that lead to increased depressive symptoms that inhibit their ability to bounce back after stressful events. Risk factors for poorer maternal mental health may include declines in father involvement and a lack of coparenting support. This study examined the connected nature of coparenting and father involvement over time among continuously unmarried mothers from the Fragile Families and Child Wellbeing Study. A bidirectional latent growth curve analysis demonstrated that early father involvement was associated with a more gradual decline in coparenting support over the child's first 5 years, while early coparenting support also predicted a slower decline in father involvement over time. Steeper declines in coparenting support and father involvement over time were linked with more maternal depression and lower maternal life satisfaction when their child was nine. Results demonstrate a clear need for targeted intervention with both parents in fragile families to promote involved fathering behavior and enhance coparental relationships.     

Differential expression of social dominance as a function of age and maltreatment experience

Recent perspectives on social dominance in normative populations have suggested a developmental progression from using primarily coercive strategies to incorporation of more socially competent strategies to attain material and social resources. Parental influences on the resource control strategies children use have been proposed but not investigated empirically. The present study examined age- and gender-related differences in dominance strategies in 470 children from high-risk neighborhoods who were between 6 and 13 years of age, approximately half of whom had experienced maltreatment. A Q-sort measure of social dominance was developed and received preliminary support. Consistent with predictions from resource control theory, age-related differences in dominance-related behavior were demonstrated in both nonmaltreated and maltreated children. Maltreated children were more likely than nonmaltreated children to be identified as dominant bullies at any age. Dominance and bullying were not more likely to be associated for children who had experienced physical and sexual abuse relative to those who were neglected or emotionally maltreated. Results are discussed in terms of the influence of maltreatment on the social development of children, and intervention approaches for limiting these deleterious effects are recommended.     

Knowledge of Performance is Insufficient for Implicit Visuomotor Rotation Adaptation

The ability to adapt is a fundamental and vital characteristic of the motor system. The authors altered the visual environment and focused on the ability of humans to adapt to a rotated environment in a reaching task, in the absence of continuous visual information about their hand location. Subjects could not see their arm but were provided with post trial knowledge of performance depicting hand path from movement onset to final position. Subjects failed to adapt under these conditions. The authors sought to find out whether the lack of adaptation is related to the number of target directions presented in the task, and planned 2 protocols in which subjects were gradually exposed to 22.5° visuomotor rotation. These protocols differed only in the number of target directions: 8 and 4 targets. The authors found that subjects had difficulty adapting without the existence of continuous visual feedback of their performance regardless of the number of targets presented in task. In the 4-target protocol, some of the subjects noticed the rotation and explicitly aimed to the correct direction. The results suggest that real-time feedback is required for motor adaptation to visual rotation during reaching movements.     

Cannabinoid receptors activation and glucocorticoid receptors deactivation in the amygdala prevent the stress-induced enhancement of a negative learning experience

The enhancement of emotional memory is clearly important as emotional stimuli are generally more significant than neutral stimuli for surviving and reproduction purposes. Yet, the enhancement of a negative emotional memory following exposure to stress may result in dysfunctional or intrusive memory that underlies several psychiatric disorders. Here we examined the effects of stress exposure on a negative emotional learning experience as measured by a decrease in the magnitude of the expected quantity of reinforcements in an alley maze. In contrast to other fear-related negative experiences, reward reduction is more associated with frustration and is assessed by measuring the latency to run the length of the alley to consume the reduced quantity of reward. We also examined whether the cannabinoid receptors agonist WIN55,212-2 (5 μg/side) and the glucocorticoid receptors (GRs) antagonist RU-486 (10 ng/side) administered into the rat basolateral amygdala (BLA) could prevent the stress-induced enhancement. We found that intra-BLA RU-486 or WIN55,212 before stress exposure prevented the stress-induced enhancement of memory consolidation for reduction in reward magnitude. These findings suggest that cannabinoid receptors and GRs in the BLA are important modulators of stress-induced enhancement of emotional memory.     

The halo model of origin images: Conceptualisation and initial empirical test

National origin has gained importance as a marketing tool for practitioners to sell their goods and services. However, because origin‐image research has been troubled by several fundamental limitations, academia has become sceptical of the current status and strategic implications of the concept. The aim of this paper was threefold, namely, to provide a state‐of‐the‐art review of origin‐image research in marketing, develop and empirically test a new origin‐image model and, present the implications of the study.

Ruminating on Rumination: are Rumination on Anger and Sadness Differentially Related to Aggression and Depressed Mood?

Rumination is a risk factor for aggression and depression, yet few studies have incorporated both aggression and depression in a unitary model that reflects how rumination predicts these distinct conditions. The current study examined rumination on anger and sadness to assess their unique relations with aggression and depressed mood, respectively. Analogous anger rumination and sadness rumination questionnaires were used to minimize measurement variance, and were completed by 226 undergraduate students. Factor analysis suggested one general rumination factor comprised of two distinct sub-factors of anger rumination and sadness rumination. Path analysis confirmed unique relations between anger rumination and aggression, and sadness rumination and depressed mood. Further, anger rumination and anger were independent predictors of aggression. Results supported the conceptualization of anger rumination and sadness rumination as distinct constructs and underscore the importance of pursuing research that incorporates both forms of rumination to better understand how they impact development, mental health, and behavior.     

The practical ethics of linguistic integration: Three challenges

Public debates on linguistic integration as a socially desired outcome often share a prevailing sentiment that newcomers ought to “learn the language.” But the intensity of that sentiment is rarely accompanied by an equally robust understanding of what, precisely, it means in practice. This results in a notion of linguistic integration with an inbuilt tension between a seemingly pragmatic and commonsensical appearance, on the one hand, and a minimal action-guidance capacity, on the other hand. This paper explores this intriguing tension, and it identifies three moral and practical challenges that this challenge presents to the normative theorizing of the practical ethics of linguistic integration: (1) a predicament of arbitrary treatment; (2) the interpersonal structure of social and linguistic learning; and (3) the affective dimension of linguistic integration.
