Compression of environmental representations following interactions with objects

Previous work reveals that interacting with all objects in an environment can compress spatial memory for the entire group of objects. To assess the scope and magnitude of this effect, we tested whether interacting with a subset of objects compresses spatial memory for all objects in an environment. Participants inspected objects in one or two unmarked regions of space, then recalled the distances between pairs of objects from memory. One group of participants picked up objects in both regions, a second group picked up objects in one region and passively viewed objects in the other region, and a third group passively viewed objects in both regions. When participants manually interacted with objects, they recalled shorter object-pair distances throughout the environment. The magnitude of this effect was the same, regardless of whether participants interacted with all objects in the environment or just a subset of them. Together, these findings suggest that interacting with objects can compress environmental representations in memory, even when observers interact with a relatively small subset of objects.     

Self-Disclosure and Spiritual Well-Being in Pastors Seeking Professional Psychological Help

Pastoral mental health is a topic that has only rarely been researched empirically in the psychological literature, yet a pastor’s mental health can have a significant impact on churches, communities, and even nations (Royal and Thompson, Journal of Psychology and Christianity, 31(3), 195–204, 2012). One of the thoughts prompting this research is that evangelical pastors might be expected to resist the findings of psychological research and lack understanding of specific mental illnesses they are potentially facing. Combined with historical and cultural dynamics that could influence resistance to professional psychological help, evangelical pastors have personal, internal factors that could also strengthen resistance, including the researched issues of self-disclosure flexibility and spiritual well-being. A correlational research design with multivariate regression was used to determine potentially significant or predictive relationships between the relevant factors. Among evangelical seminary students (N = 251) preparing for parish-based pastoral ministry, this research determined that no significant relationship, predictive or otherwise, existed between self-disclosure flexibility, spiritual well-being, and attitudes toward seeking professional psychological help. Implications include a shift in focus toward external factors influencing pastors’ help-seeking attitudes, such as the need for the mental health community to develop connections with evangelical pastors and the development of more support for Christian mental health professionals in the larger evangelical community.     

Particularism about Composition

Unwilling to adopt the radical ontologies that leading answers to van Inwagen's special composition question imply, Ned Markosian proposes that there is no true, non‐trivial, and finitely long answer to the SCQ. On my usage, this makes Markosian a particularist about composition. I argue that an improved version of Markosian's particularism fails because it cannot explain how sense perception justifies many of the ordinary‐object beliefs we base on it. I further argue that psychologists' research on object perception suggests that general principles govern how we perceptually discriminate unified wholes from mere pluralities, and this narrows the range of answers to the SCQ available to commonsense ontologists.     

A Cyber Phenomenon: A Q-Analysis on the Motivation of Computer Hackers

In computer security parlance, a hacker is an individual who actively seeks and takes advantage of flaws and weaknesses of a computer network or system. In recent years, one has seen the rise of hacking, often as a form of protest and retaliation for reasons ranging from political to social, but the question remains as to what really motivates an individual to hack a computer network? Using the Q-method, the study aimed to develop a classification of the motivation of computer hackers. This was done with the use of 43 participants who were subjected to preliminary interviews and the sorting method. The statements from the interviews were categorized that resulted in seven conceptual themes, namely social-positive, social-negative, intellectual gain, self-satisfaction, economic rewards, technological-positive and technological-negative. From these themes, three distinct profiles emerged and were used to describe the motivation of hackers.     

Minority Stress and the Risk of Unwanted Sexual Experiences in LGBQ Undergraduates

Sexual assault is prevalent among lesbian, gay, bisexual, and queer (LGBQ) college students, but its relationship to anti-LGBQ stigma has not been established. The goal of the present study was to determine whether minority stress, specifically internalized homophobia, predicted unwanted sexual experiences among LGBQ undergraduates (N = 763), whether routine behaviors (number of consensual sexual partners and alcohol use) mediated this relationship, and whether sense of LGBTQ community was a protective factor. Significant proportions of sexual minority men (10 %), women (18 %), and non-binary or transitioning students (19 %) reported an unwanted sexual experience since entering college. Internalized homophobia was associated with greater risk of unwanted sexual experiences. It also had a negative indirect effect on unwanted sexual experience risk through a negative association with number of sexual partners. Alcohol use did not mediate the relationship between internalized homophobia and unwanted sexual experiences. Sense of LGBTQ community was associated with lower risk, mediated by lower levels of internalized homophobia. The relationships between internalized homophobia and unwanted sexual experience risk were similar for women and men. These findings demonstrate that minority stress increases LGBQ students’ risk of sexual victimization and that in-group social relationships can mitigate this risk. We argue that minority stress is an important risk factor for sexual violence. Violence prevention interventions should attempt to reduce internalized homophobia, and colleges and high schools should establish LGBQ-affirming social climates and provide resources for LGBQ students, including targeted violence prevention efforts and programs that foster a sense of supportive community.     

Associating a time‐based prospective memory task with an expected context can improve or impair intention completion

Three experiments investigated time‐based prospective memory defined here as remembering to fulfil an intention during a later window of time. When people associated the response window with a future context, time‐based responding was better if that context expectation was correct as compared with having no context expectation at all. By contrast, if the response window occurred in a context that preceded the expected context, time‐based performance was worse than having no context expectation at all. An explicit reminder about the intention was sufficient to ameliorate the decrement found with an incorrect context association. However, successfully completing a different, event‐based prospective memory intention was not sufficient to overcome the incorrect context association. The authors assert that possessing such associations alters normal monitoring of the passage of time which in turn leads to the pattern of results obtained.

Reasoning about make-believe and hypothetical suppositions: Towards a theory of belief-contravening reasoning

The present study explores how suppositions which conflict with accepted beliefs are represented and reasoned about. Two studies test the predictions regarding the nature and developmental changes in children's ability to represent and reason about hypothetical or make-believe suppositions which violate their everyday knowledge and beliefs. In Study 1, 46 4th- and 5th-graders were introduced to a hand puppet, Freddy, who made claims inconsistent with generally accepted beliefs (e.g., “all dogs meow”) because he was pretending (Make-Believe Condition) or believed them (Hypothetical Condition). Participants were asked to think like Freddy and judge whether a conclusion (“There's a dog; does it meow?”) follows logically from the claim. In Study 2, 40 kindergarten (6-year-olds), 3rd–4th grade (10-year-olds), and college students were asked to represent belief contravening make-believe (pretend in a make-believe world that dogs meow) and hypothetical (imagine what the real world would be like if dogs meow) premises, evaluate conclusions of the premises (Rover is a dog, does Rover meow?) and make judgments about the attributes (growl, wag tail, purr, and eat mice) of the entity (a meowing dog) they created. The prediction that it would be easier to represent and reason from belief-contravening suppositions in the Make-Believe than Hypothetical conditions was confirmed in each study, although the two forms of reasoning were directly correlated (Study 2). The results were discussed in terms of the similarities (compartmentalization and integration) and differences (reconciliation) of processes involved in fancifully (make-believe) or seriously (hypothetical) representing and reasoning about belief-contravening suppositions.     

Social validity: Perceptions of check and connect with early literacy support

This article underscores the potential advantages of qualitative methods to illustrate the depth and complexity of social validity. This investigation evaluates the social validity of Check and Connect with Early Literacy Support (CCEL), through the perspectives of teachers and caregivers whose children participated in the intervention. Teachers from six classrooms and caregivers from six families participated in evaluating the social validity of this intervention using a combination of qualitative and quantitative methods. Participants completed the Treatment Acceptability Rating Scale—Revised (TARF-R; Reimers, T. M., Wacker, D. P., Cooper, L. J. & DeRaad, A. O. (1992). Clinical evaluation of the variables associated with treatment acceptability and their relation to compliance. Behavioral Disorders, 18(1), 67-76.), a quantitative measure of treatment acceptability (a component of social validity), and were interviewed using qualitative interviews and focus groups. Results were analyzed through ethnographic methodology and indicate complex, reciprocal relationships among factors related to social validity. This investigation is considered in light of recent efforts to develop a systematic approach to evaluate the adequacy of intervention research using qualitative methods.     

Learning in the brain–computer interface: insights about degrees of freedom and degeneracy from a landscape model of motor learning

In this paper, we examine the role of degrees of freedom and their degeneracy in learning in the brain–computer interface paradigm. Though the traditional notion of degrees of freedom in motor learning gave emphasis to muscle and joint activity, the broader concept of dimensions of behavior is relevant to brain–computer interface learning where there is no muscle activity. The role of degeneracy in the dimensions of brain activity is proposed to enhance learning through robustness to stability loss and adaptability in the search for new stable states. Principles for the application of augmented information for learning to coordinate and control the degenerate degrees of freedom in the brain–computer interface are outlined.
