Dissociation of visual localization and visual detection in rhesus monkeys (Macaca mulatta)

Conscious and unconscious cognitive processes contribute independently to human behavior and can be dissociated. For example, humans report failing to see objects clearly in the periphery while simultaneously being able to grasp those objects accurately (Milner in Proc R Soc B Biol Sci 279:2289–2298, 2012). Knowing whether similar dissociations are present in nonverbal species is critical to our understanding of comparative psychology and the evolution of brains. However, such dissociations are difficult to detect in nonhumans because verbal reports of experience are the main way we discriminate putative conscious from unconscious processing. We trained monkeys in a localization task in which they responded to the location where a target appeared, and a matched detection task in which they reported the presence or absence of the same target. We used masking to manipulate the visibility of targets. Accuracy was high in both tasks when stimuli were unmasked and was attenuated by visual masking. At the strongest level of masking, performance in the detection task was at chance, while localization remained significantly above chance. Critically, errors in the detection task were predominantly misses, indicating that the monkeys’ behavior remained under stimulus control, but that the monkeys did not detect the target despite above-chance localization. While these results cannot establish the existence of phenomenal vision in monkeys, the dissociation of visually guided action from detection parallels the dissociation of conscious and unconscious vision seen in humans.     

Saved by Trauma: A Psychoanalytical Reading of the Atonement

This work offers a Lacanian account of the work of Christ on the cross. It proffers a Holy Saturday theology in which God has to embrace suffering and death in its entirety in order to end the stranglehold of the world's system of sacrifice; the divine took on death as a constitutive factor. A reading of the atonement is constructed in which a diabolical system is shattered from within by the actions of a unique victim; it also relates the vicarious element of the atonement to the psychoanalytical concept of transference. Ultimately, this article hopes to contribute to the ongoing interaction between psychoanalysis and theology. Naturally it also hopes to influence the debate over which discursive “model” of the atonement is most helpful.     

Trait Anxiety and Fear Responses to Safety Cues: Stimulus Generalization or Sensitization?

Abnormal fear responding to threat cues may contribute to the aetiology and maintenance of persistent fears and pathological anxiety. Chronic anxiety may also involve abnormal fear responding to ??safety?? cues, which do not signal danger. Yet investigations of fear responding to acquired safety cues are scarce and the basis of such responding remains unclear. Moreover, previous studies do not distinguish between stimulus generalization (an associative mechanism based on perceptual similarity between threat and safety cues) and sensitization (a non-associative mechanism whereby fear responses to any novel, intense, or fear-related stimulus are temporarily elevated). This study investigated responses to acquired safety cues in volunteers with varying trait anxiety, using a novel fear conditioning paradigm designed to distinguish between effects of trait anxiety on generalization and sensitization. The paradigm used three conditioned stimuli: a threat cue (CS+) and two safety cues (CS?), one perceptually similar to the CS+ and one perceptually dissimilar. Conditioned fear to these cues was indexed by fear potentiation of the startle blink reflex, skin conductance responses, and self-report. To examine how trait anxiety moderated responses to safety cues, participants were divided into high and low trait anxiety subgroups. Startle, skin conductance, and self-reported fear measures indicated that generalization of fear occurred for the safety cue which resembled the threat cue, but not for the perceptually dissimilar safety cue, consistent with the stimulus generalization hypothesis. There was some evidence that stimulus generalization was exaggerated in anxious individuals. The current study sheds light on the mechanism by which fear responses to safety cues arise in healthy individuals, and offers some insight into the influence of this mechanism in chronic anxiety.

Adolescents' family obligation and activities in rural and urban Vietnam: Implications for social change

This study examined how urbanisation may modify adolescents' values and activities concerning family obligation by surveying 572 adolescents (M_age = 15.75, SD = .73) in rural and urban Vietnam. Compared with their rural peers, urban adolescents reported a stronger sense of family obligation but spent less time actually engaging in family assistance, findings that were partly explained by urban households' less financial hardship and higher parental education levels. As expected, stronger family obligation values were associated with greater family assistance activities across rural and urban Vietnam. However, stronger family obligation values were associated with more study hours only in urban Vietnam, indicating that urbanisation may broaden the meaning of family obligation to encompass the academic domain. Additionally, weaker family obligation values were associated with more employment hours only in rural Vietnam, suggesting that rural adolescents with little attachment to the traditional value of family obligation may pursue autonomy through employment outside the home. In traditionally familistic societies undergoing urbanisation, family obligation may take on different meaning depending on adolescents' ecological settings that construct cultural values and behavioural norms.     

2003 Division 35 Presidential Address: Feminist Leadership: Feminist Visions And Diverse Voices

Although the theories and models on feminism and leadership exist, there has been little study of the intersection of the two. The literature on feminist leadership is scant. Few have defined it and fewer still have researched it. Thus, Feminist Leadership was chosen for my presidential initiative. This initiative kicked off a dialogue about feminist leadership that is summarized in this article. The article is based on my presidential address presented at the 2003 Annual Convention of the American Psychological Association in concluding my year as President of Division 35, the Society for the Psychology of Women. It identifies some challenges faced by women in leadership positions and by feminist leaders. It identifies the major issues that emerged during a web-based dialogue about feminist leadership. It discusses the intersection between theories of leadership and feminism. It ends with the lessons learned and implications for the future of feminist leadership.
