Psychopathic traits and preattentive threat processing in children: a novel test of the fearlessness hypothesis

We tested the fearlessness hypothesis of psychopathy in an at-risk sample of 88 preadolescent children. Psychopathy was measured using combined child- and parent-reported scores on the Antisocial Process Screening Device (APSD). Using a continuous-flash-suppression paradigm, we evaluated threat processing at the preattentive level for the first time in a study of psychopathy. Scores for the APSD Callous/Unemotional factor, which assesses the core affective deficits of psychopathy, predicted preattentive face-recognition deficits for fearful faces and, to a lesser extent, for disgusted faces. This finding contradicts recent suggestions that the fearlessness associated with psychopathy is solely a consequence of overt attentional artifacts. Future research should focus on preattentive processing of fear in individuals with callous-unemotional traits, and on the implications of preattentive-processing deficits for treatment and theory development.     

Looking versus seeing: Strategies alter eye movements during visual search

Visual search can be made more efficient by adopting a passive cognitive strategy (i.e., letting the target “pop” into mind) rather than by trying to actively guide attention. In the present study, we examined how this strategic benefit is linked to eye movements. Results show that participants using a passive strategy wait longer before beginning to move their eyes and make fewer saccades than do active participants. Moreover, the passive advantage stems from more efficient use of the information in a fixation, rather than from a wider attentional window. Individual difference analyses indicate that strategies also change the way eye movements are related to search success, with a rapid saccade rate predicting success among active participants, and fewer and larger amplitude saccades predicting success among passive participants. A change in mindset, therefore, alters how oculomotor behaviors are harnessed in the service of visual search.     

Leverpress Escape/Avoidance Conditioning in Rats: Safety Signal Length and Avoidance Performance

Leverpress escape/avoidance is an excellent model for assessing coping in rats. Acquisition of the leverpress response is determined by the interstimulus (signal-shock) interval, as well as the type and duration of the aversive event. One factor that has received less research attention is the safety or feedback signal. The safety signal presumably negatively reinforces leverpress responding through fear reduction. Here, we present a parametric manipulation of safety signal length and avoidance performance. All rats were trained with a 60-s tone conditioned stimulus and an intermittent 1-s, 1.0-mA footshock. Training was further accomplished with a 1-, 2-, 4-, or 6-min safety signal. Acquisition of the avoidance response was comparable at all safety signal durations. Rats trained with the shortest safety signal (1 min) exhibited more leverpresses during the safe period, a measure of anxiety. Thus, acquisition of the leverpress avoidance response was efficient regardless of safety signal duration, even though shorter periods were associated with greater anxiety.     

Moral Lumps

Can all goods or bads be broken down into smaller and smaller pieces? Can all goods or bads be added together with some other good or bad to get a larger amount? Further, how does moral significance track the disaggregation and the aggregation of moral goods and bads? In Part 1, I examine the limits placed on aggregation by moderate deontological moral theories. This paper focuses in particular on the work of Judith Thomson and T.M. Scanlon as well as on some of my own past work on the question of aggregation in the context of overriding rights. In Part 2, I examine consequentialist criticism that harms and benefits can be broken down into smaller pieces than the deontological theory allows and the argument that the moderate deontological view is too permissive since it allows aggregation of benefits within a single person's life. In Part 3 I suggest how a moderate deontological moral theory might respond to the criticisms. I cast my answer in terms of the existence of lumpy goods and bads. I argue that consequentialist critics of deontology are wrong to insist that all goods and bads can be disaggregated and aggregated at will. Instead, I offer the suggestion that most, or many, goods and bads come in morally significant lumps. That said, it will not always be obvious what those lumps are. Determining the texture of moral value is a substantive project in normative ethics. All I have hoped to do in this paper is suggest that two standard positions on how to group moral value are mistaken and give hope that we need not adopt one of the two. Part 4 of the paper responds to an objection and sets the stage for further work in value theory.     

Spirituality and Psychosocial Development in Middle-Age and Older Adults with Vision Loss

The purpose of this study was to examine the buffering effects of spirituality on stress resulting from vision status, health status, and from other significant life events as related to psychosocial development according to Erikson's 8-stage theory. Participants were middle-aged and older adults with recent vision loss who had applied for vision rehabilitation services (n = 195). The regression model included independent factors of sociodemographic variables, life stress measures (i.e., vision status, health status, and life experience ratings), mediating variables (i.e., spirituality, religiousness, and social support), and the outcome of psychosocial development. Spirituality was found to play a buffering role on the effects of negative life experience impact and control ratings. Vision impairment status did not appear to either promote or hinder psychosocial development.     

Recognition and personhood: A critique of Bernstein's account of the wrongfulness of torture

J. M. Bernstein argues that to capture the depths of the harm of torture, we need to do away with the idea that we possess intrinsic and inviolable worth. If personhood is inviolable, then torture can inflict only apparent harm on our standing as persons. Bernstein claims that torture is a paradigm of moral injury because it causes what he calls “devastation”: The victim experiences an actual degradation of his or her personhood. Bernstein argues that our value is given to us through mutual recognition and hence can be lost. In this paper, I argue that if our human value can be lost, then it first must be built up. If it must be built up, then the question of our status before the building begins must be answered. Bernstein faces a problem of human beings who fall outside relations of mutual recognition and hence are valueless. His best option for answering this problem is to point to the centrality of the body in his account of recognition, but doing so reveals a notion of intrinsic worth implicit in his account. I call for a revision of Bernstein's account that can hold on to devastation without eschewing intrinsic worth.     

Saccade preparation inhibits reorienting to recently attended locations

We measured manual reaction time in normal human subjects to confirm that an eccentric visual signal has a biphasic effect on covert attention and eye movements. First, it summons attention and biases a saccade toward the signal; a subsequent inhibition of return then slows responses to signals at that location. A temporal hemifield dominance for inhibition of return was shown; this finding converges with observations in neurologic patients to suggest that it is mediated by midbrain pathways. Endogenous orienting of attention, from a central arrow cue, did not activate inhibition of return, whereas endogenous saccade preparation did so as effectively as an exogenous signal, even when no saccade was made. Inhibition of return is activated by midbrain oculomotor pathways and may function as a location "tagging" mechanism to optimize efficiency of visual search.     

Explanatory style and Immunoglobulin A (IgA).

The construct of explanatory style has been related to numerous aspects of human psychology, including health. Our research has focused on the effects of various psychological variables on the immune system, in particular Immunoglobulin A (IgA). We had participants fill out the Attributional Style Questionnaire (ASQ), the predominant measure of explanatory style, and assayed saliva samples for secretory IgA. No relationship was observed between overall ASQ score and IgA, or composite optimism score and IgA. However, we observed significant negative correlations between both the composite pessimism score and IgA, as well as the hopelessness score and IgA. Pessimistic explanatory style may therefore be related to immune system deficits and poor health.     

Current and past depression as predictors of family functioning: a comparison of men and women in a community sample.

The association between family functioning and parental depression has primarily been studied in samples of women. In particular, very little research exists that examines how parent gender and past diagnoses of depression are related to family functioning. The family relationships of 469 couples from a community sample were examined using self- and partner report measures of the marital relationship and youth report and interviewer-rated measures of the parent-youth relationship. Both currently and formerly depressed men and women were shown to have poorer family functioning than nondepressed and never depressed individuals, respectively. Interactions of gender and depression status indicated that depression and poorer marital functioning were more strongly related for women than for men, but there were few gender differences in the parent-youth relationship. The results highlight the need for further research on men's family functioning and suggest that targeting current depressive symptoms in treatment may not be sufficient to resolve marital and parent-youth difficulties that endure after depressive episodes remit.
