A comparison of monocular and binocular depth perception in 5- and 7-month-old infants

Monocular depth perception was compared with binocular depth perception in 5- and 7-month-old infants. Reaching was used as the dependent measure. Two objects, identical except in size, were presented simultaneously to each infant. The smaller object was within reach for the infants while the larger object was just beyond reach. The two objects subtended equal visual angles from the infants' observation point. With binocular presentation, 96% of the 7-month-olds' reaches and 89% of the 5-month-olds' reaches were for the nearer object. With monocular presentation, 58% of the 7-month-olds' reaches and 65% of the 5-month-olds' reaches were for the nearer object. The reaching preferences observed in the monocular condition indicated sensitivity to monocular depth information (motion parallax, accommodation, and relative size information were available). Binocular viewing, however, resulted in a far more consistent tendency to reach for the nearer object. This result suggests that the infants' perception of the objects' distances was more veridical in the binocular condition than in the monocular condition.     

The selective impact of question form and input mode on the symbolic distance effect in children

Five experiments are reported on the symbolic distance effect (SDE) and related phenomena with 6- and 9-year-old children. In the first of these, children were asked to judge the relative sizes of animals in verbal and pictorial tests featuring the comparatives "bigger" and "smaller." A perceptual condition with actual objects was included by way of comparison. A Symbolic Distance Effect was obtained for both lexical and pictorial input. Mode differences were also observed. Pictures produced faster responses than words, and congruity effects occurred only in the pictorial condition. Although performance was similar in tests with either comparative, our subsequent experiments on both 6- and 9-year-olds reveal a significant asymmetry in the child's capacity to verify statements of relation as a function of the direction along the (size) continuum implied by the question. However, important differences between age groups also apparent in the data lead us to conclude that the older subjects develop strategies to overcome this asymmetry by translating certain statements of relation into a form more congruent with their natural modes of encoding.     

Variations in explicitly unpaired training are differentially effective in producing conditioned inhibition

To evaluate a contingency interpretation of conditioned inhibition (CI), rats were given “explicity unpaired” training in which the locus and duration of a CS within the inter-US (shock) interval were systematically manipulated for different groups. Summation and retardation tests in Experiment 1 indicated that stronger CI resulted from both a backward and a trace CS than from a midlocus CS of equal or greater duration. Complementing these findings, the same tests in Experiment 2 showed that, by comparison with novel-stimulus controls, CI developed to a trace CS but not to a mid-locus CS, nor to a trace CS that was accompanied by an immediate signal for the US. These findings argue against a contingency interpretation of CI and favor a contiguity interpretation stressing the short-term rehearsal of stimulus events. Such rehearsal of the US allows a backward CS, but not a mid-locus CS with an extended US-CS interval, to be discriminated as a signal for nonreinforcement, and thus to develop as a conditioned inhibitor. Similarly, excitatory conditioning to the memory trace of a CS allows the nominal trace CS to develop as a signal for nonreinforcement, and thus as a conditioned inhibitor, but not when its memory trace is overshadowed by another CS that immediately precedes the US. In short, the development of CI is facilitated when excitation is mediated by the memorial processing of either the US or a discrete CS for the US rather than by contextual cues.     

Depressed mood and environmental mastery as potential pathways linking family relationship quality and disease self-management for African Americans with hypertension

African Americans are at significantly greater risk of hypertension and worse cardiovascular outcomes than other racialized groups, yet hypertension intervention effects remain limited. Thus, it is necessary to understand the potential mechanisms whereby interventions may be more effectively targeted to improve health. Supported by prior research evidence and guided by the Biobehavioral Family Model, this study examined associations between family relationship quality, psychological wellbeing, and self-management behaviors for African Americans with hypertension. Data were pooled from three Midlife Development in the U.S. projects, resulting in a sample of 317 African Americans (63.4% female, M_age = 53.32) with self-reported high blood pressure in the past 12 months. We tested four cross-sectional multiple mediator models, with depressed mood and environmental mastery mediating associations between family strain and exercise, smoking, problematic alcohol use, and stress-eating. Environmental mastery mediated the association between greater family strain and decreased odds of achieving recommended exercise levels; greater odds of reporting problematic alcohol use; and greater stress-eating. Though family strain was associated with depressed mood in each model, this variable did not serve as an indirect pathway to self-management behaviors. Family strain, and the potential pathway identified via environmental mastery, may be a meaningful predictor of disease self-management for African Americans with hypertension. Longitudinal studies are needed to examine directionality and to support intervention trials for improving self-management and hypertension outcomes.     

Take care of egotism,and redemption will take care of itself: Comments on Tracy Llanera's Richard Rorty: Outgrowing modern nihilism

This commentary critically examines two facets of Tracy Llanera's recent book Richard Rorty: Outgrowing Modern Nihilism. First, it considers her interpretation of Richard Rorty's redemptive project. It argues that, while Llanera succeeds in resolving tensions in Rorty's public-private distinction, her account downplays the role of abnormal discourse within projects of self-creation. Second, it raises several questions about Llanera's strategy for situating this redemptive project within debates concerning existential nihilism. On her view, one ought to follow Rorty in addressing the problem of egotism instead of the problem of nihilism, since the former is prior to the latter. But it is not clear who counts as an egotist, or why egotists are especially prone to becoming nihilists. Moreover, there are reasons to think that egotism and nihilism are fundamentally different kinds of problems.     

Jung’s Psychoid Monism

Jung’s final psychoid theory of archetypes was an additional attempt to find a solution to the philosophical problem of how to relate mind and matter. In the following essay Jung’s solution is summarized by a set of 17 theses, and Jung’s philosophy will be called psychoid monism. According to psychoid monism, what ultimately and primarily is, is the psycho-physically neutral domain of instinctual experience. The origin of this view can be traced back to Post-Kantian German Idealism (Schopenhauer, Schelling, Hölderlin), and a systematization of the view requires a dialectic approach and, in particular, contradiction-tolerant dialectic logic.     

RESCUE AND RECOVERY AS A THEOLOGICAL PRINCIPLE,AND A KEY TO MORALITY IN EXTRATERRESTRIAL SPECIES

New theological understanding can emerge with the advancement of scientific knowledge and the use of new concepts, or older concepts in new ways. Here, the authors present a proposal to extend the concept of “rescue and recovery” found in the United Nations Law of the High Seas, off-world and within a broader purview of other intelligent and self-aware species that humans may someday encounter. The notion of a morality that extends to off-world species is not new, but in this analysis, rescue and recovery become an imperative when any intelligent and self-aware species is in harm's way. Rescue and recovery encompass a necessary action component except perhaps in those cases where rescuers are in danger. The authors explore three biblical examples of rescue and recovery to derive a fundamental meaning of the concept.     

A Model for Adapting Evidence-Based Interventions to Be LGBQ-Affirmative: Putting Minority Stress Principles and Case Conceptualization Into Clinical Research and Practice

The mental health field now possesses clinical trials attesting to the efficacy of affirmative practice with sexual minority individuals. With the goal of efficiently moving the results of these clinical trials into real-world clinical practice, this paper offers a model for adapting existing evidence-based practices originally developed for the general population to be lesbian, gay, bisexual, and queer (LGBQ)-affirmative. The adaptation model presented here guides clinicians to incorporate six LGBQ-affirmative transtheoretical principles of change into practice. These principles facilitate raising awareness of the impact of minority stress on sexual minority clients’ mental health and on client self-evaluation while drawing upon sexual minority resilience and intersectional experiences to build empowering coping skills and validating relationships. The adaptation model also provides a transtheoretical approach to case conceptualization that directs clinicians to consider the role of early and ongoing minority stress on sexual minority clients’ cognitive, affective, motivational, behavioral, and self-evaluative experiences that maintain current distress. This case conceptualization approach highlights common associations among these experiences, suggesting clear routes of interventions for many sexual minority client presentations. Case examples from recent clinical trials of LGBQ-affirmative cognitive-behavioral therapy illustrate how these principles and this case conceptualization can be effectively utilized in practice. While the principles and case conceptualization are meant to be transtheoretical and therefore applicable across therapeutic techniques, to date they have been tested only in clinical trials for cognitive-behavioral treatments. Therefore, this paper concludes with a call for future research to determine the effectiveness of implementing this adaptation model across diverse therapeutic modalities and client presentations.
