Evolved navigation theory and horizontal visual illusions

Environmental perception is prerequisite to most vertebrate behavior and its modern investigation initiated the founding of experimental psychology. Navigation costs may affect environmental perception, such as overestimating distances while encumbered (Solomon, 1949). However, little is known about how this occurs in real-world navigation or how it may have evolved. We manipulated the most commonly navigated surfaces with a non-intuitive cost derived from evolved navigation theory. Observers in realistic settings unknowingly overestimated horizontal distances that contained a risk of falling and did so by the relative degree of falling risk. This manipulation produced previously unknown, large magnitude illusions in everyday vision in the environments most commonly navigated by humans. These results bear upon predictions from multiple fundamental theories of visual cognition.     

Integrative problem-centered metaframeworks therapy II: planning, conversing, and reading feedback

This is the second of 2 articles presenting Integrative Problem Centered Metaframeworks (IPCM) Therapy, a multisystemic, integrative, empirically informed, and common factor perspective for family, couple, and individual psychotherapy. The first article presented IPCM's foundation concepts and Blueprint for therapy, focusing on the first Blueprint component—Hypothesizing or assessment. This article, focusing on intervention, presents the other 3 Blueprint components—Planning, Conversing, and Feedback. Articulated through the Blueprint, intervention is a clinical experimental process in which therapists formulate hypotheses about the set of constraints (the Web) within a client system that prevents problem resolution, develop a therapeutic Plan based on those hypotheses, implement the Plan through a coconstructed dialogue with the clients, and then evaluate the results. If the intervention is not successful, the results become feedback to modify the Web, revise the Plan, and intervene again. Guided by the therapeutic alliance, this process repeats until the presenting problems resolve. IPCM Planning sequentially integrates the major empirically and yet‐to‐be empirically validated therapies and organizes their key strategies and techniques as common factors. Conversing and Feedback employ empirical STIC^® (Systemic Therapy Inventory of Change) data collaboratively with clients to formulate hypotheses and evaluate interventions. This article emphasizes the art and science of IPCM practice.     

A perceptually based comparison of image similarity metrics

The assessment of how well one image matches another forms a critical component both of models of human visual processing and of many image analysis systems. Two of the most commonly used norms for quantifying image similarity are L1 and L2, which are specific instances of the Minkowski metric. However, there is often not a principled reason for selecting one norm over the other. One way to address this problem is by examining whether one metric, better than the other, captures the perceptual notion of image similarity. This can be used to derive inferences regarding similarity criteria the human visual system uses, as well as to evaluate and design metrics for use in image-analysis applications. With this goal, we examined perceptual preferences for images retrieved on the basis of the L1 versus the L2 norm. These images were either small fragments without recognizable content, or larger patterns with recognizable content created by vector quantization. In both conditions the participants showed a small but consistent preference for images matched with the L1 metric. These results suggest that, in the domain of natural images of the kind we have used, the L1 metric may better capture human notions of image similarity.     

Parsimony and Complexity: Developing and Testing Theories of Affective Intelligence

The theory of affective intelligence posits that an individual's emotions help govern a reliance on political habits or, alternatively, deliberation and attention to new political information. Some of the evidence adduced draws on the fact that voters who are anxious about their own party's candidate do not rely blindly on their partisanship but instead consider policy and personality when they vote. In a provocative paper, Ladd and Lenz (2008 ) argue that emotions reflect an evaluative judgment, akin to likes and dislikes, that has little to say about attention and habit. Here we examine the ANES data from 1980 to 2004 and find that the affective intelligence theory's original findings remain statistically robust. On closer examination, we also learn that Ladd and Lenz reformulated the theoretical test by using a different operationalization of affect and a different dependent variable and found results at variance from ours. We find it an inappropriate test. In the end, we agree with Ladd and Lenz that cross‐sectional data cannot crisply test the short‐term impact of emotions on attention and habit and concur that ultimately experiments will move the debate forward. We further observe that Brader's (2005, 2006 ) powerful field experiments explicitly test the special effect of emotions on attention and judgment and support the affective intelligence model.     

On Habermas’s Critique of Husserl

Over four decades, Habermas has put to paper many critical remarks on Husserl’s work as occasion has demanded. These scattered critical engagements nonetheless do add up to a coherent (if contestable) position regarding the project of transcendental phenomenology. This essay provides a comprehensive reconstruction of the arguments Habermas makes and offers a critical assessment of them. With an eye in particular to the theme of intersubjectivity (a theme of fundamental interest to both thinkers), it is argued that Habermas’s arguments do indeed show up deficiencies in Husserlian phenomenology and yet that they do not succeed in proving that we must abandon the methods and tasks of phenomenological research. On the contrary, it is argued that phenomenological methods may well be needed in order to investigate certain philosophical questions that Habermas’s theory of communication has thus far only partially addressed.     

Physical self-concept and self-esteem mediate cross-sectional relations of physical activity and sport participation with depression symptoms among adolescent girls.

The authors tested whether physical self-concept and self-esteem would mediate cross-sectional relations of physical activity and sport participation with depression symptoms among 1,250 girls in 12th grade. There was a strong positive relation between global physical self-concept and self-esteem and a moderate inverse relation between self-esteem and depression symptoms. Physical activity and sport participation each had an indirect, positive relation with global physical self-concept that was independent of objective measures of cardiorespiratory fitness and body fatness. These correlational findings provide initial evidence suggesting that physical activity and sport participation might reduce depression risk among adolescent girls by unique, positive influences on physical self-concept that operate independently of fitness, body mass index, and perceptions of sports competence, body fat, and appearance.     

The experience of outsourcing transfer: implications for guidance and counselling

Outsourcing can involve the forced transfer of employees to another organisation. During or after the transfer they may find their jobs have changed or go through a process of downsizing. They also often have to maintain a relationship with their previous employer as they continue to work on joint projects. In this paper we review relevant research literature and identify important psychological and organisational processes involved in this process, which are of specific interest to guidance and counselling. We also present data from a longitudinal research study in which employees undergoing an outsourcing transfer discussed their experiences. A number of these employees required career counselling and some were undergoing psychological counselling to reduce depression and anxiety. In conclusion, we summarise important issues to be considered by the counsellor when advising individuals going through this process.     

On Black Women, “In Defense of Transracialism,” and Imperial Harm

This essay is a response to the events surrounding Hypatia's publication of “In Defense of Transracialism.” It does not take up the question of “transracialism” itself, but rather attempts to shed light both on what some black women may have experienced following from the publication of the article and on how we might understand this experience as harm. It also suggests one way for feminist journals to reduce the likelihood of similar harms occurring in the future. I begin by describing a discussion that occurred in my classroom that bears some resemblance to the much larger debate that emerged around Hypatia. Next, I elaborate a concept of imperial harm. I then address how this concept comes to be relevant to the experience of black women within the discipline of philosophy in general, before briefly describing how academic feminism (including feminist philosophy) has served as a particular site of imperial harm for black women. Finally, touching on the idea of expressive harm, I conclude with an appeal for the adoption of more feminist publication ethics.     

Spirituality and transformation in a community-based group in the Bahamas

Understanding the specific contexts where spirituality may or may not be helpful has been identified as a priority in spirituality and health research. The study aims were to clarify the helpfulness of spirituality and the interrelationships among transformation, spirituality, and forgiveness in this community-based group offered in a societal context of violence. Sixteen group participants from the Bahamas were selected and interviewed. Nine participants were female (56%); 75% identified as Black and 25% identified as White/Caucasian. NVivo 11 software was used. Transformation and spirituality themes were prevalent: themes related to prayer, group connection, and compassion were prominent. Selected spirituality themes were proximal to transformation themes, particularly forgiving others. The group process themes were closely linked to transformation themes. Participants noted that modelling by the group provided support for them to forgive and change. These findings may inform future efforts to intervene in communities experiencing violence and societal fragmentation.
