Through neural stimulation to behavior manipulation: a novel method for analyzing dynamical cognitive models

The dynamical systems' approach to cognition (Dynamicism) promises computational models that effectively embed cognitive processing within its more natural behavioral context. Dynamical cognitive models also pose difficult, analytical challenges, which motivate the development of new analytical methodology. We start by illustrating the challenge by applying two conventional analytical methods to a well-known Dynamicist model of categorical perception. We then introduce our own analysis, which works by analogy with neural stimulation methods, and which yields some novel insights into the way the model works. We then extend and apply the method to a second Dynamicist model, which captures the key psychophysical trends that emerge when humans and animals compare two numbers. The results of the analysis-which reveals units with tuning functions that are monotonically related to the magnitudes of the numbers that the agents must compare-offer a clear contribution to the contentious debate concerning the way number information is encoded in the brain.     

When Does Religious Racial Integration “Count?” A Caution About Seeking Ideal Ethnographic Cases

If the particular demographics of attenders, their storied backgrounds, and the peculiar aspects of their social and economic circumstances fail to conform to an “ideal scenario” of “ultimate” diversity, we might find ourselves disappointed. This appears to be one of the most important aspects of Richard Pitt's critique. Pitt desires a different “ideal” case for analysis, a church with black leadership and a clear black dominance that successfully integrates whites. Such an analysis is sorely needed, but this does not reflect the dynamics of Oasis nor does it address what has been one of the most pressing questions among scholars of diversity over the past decade. Given that any black‐white integration is rare, I would not so easily dismiss the specifics of this case. Indeed, rather than merely reverse the case, I want to radicalize the critique. It is time to more purposefully examine diversity beyond the “racial divide,” and I suggest here several ways we can expand the research agenda on diverse congregations.     

Development and validation of the Eyewitness Metamemory Scale

Metamemory can be defined as the knowledge about one's memory capabilities and about strategies that can aid memory. In this paper, we describe the development and validation of the Eyewitness Metamemory Scale (EMS), tailored specifically for use in face memory and eyewitness identification settings. Participants (N = 800) completed the EMS and other measures on general metamemory. Results from exploratory and confirmatory factor analysis revealed good factorial validity, internal consistency, and content validity. The EMS items emerged into three distinct factors: memory contentment, memory discontentment, and memory strategies. The EMS is a brief and easily administrable questionnaire that might be used to assess self‐ratings of face recognition capacity and use of strategies to encode faces.     

First impressions online: The inclusion of transgender and gender nonconforming identities and services in mental healthcare providers' online materials in the USA

Background: When accessing mental healthcare services, transgender and gender nonconforming (TGNC) individuals face systemic barriers to gender-affirmative care. Initial points of contact, like intake forms, may show limited consideration for the heterogeneity of TGNC identities and can lead to negative consequences prior to face-to-face interaction with providers. Aims: The first aim was to mimic a likely pathway a TGNC individual may follow to seek mental healthcare services in the USA and to describe the extent to which they may encounter enacted stigma or affirmative messages that may impede or facilitate access to care. The second aim was to determine if a positive State legal climate for TGNC people was associated with more affirmative provider materials. Methods: Content analysis was used to examine a national sample of websites and intake forms of mental healthcare providers who advertise online as working with TGNC clients. Intake forms were coded for usage of affirmative language in gender/sex questions and including questions for a client's pronouns and preferred name. Websites were coded for mentioning a variety of services or resources for TGNC clients. Results: While provider websites were found through Google searches for a “gender therapist,” only 56.6% of websites stated a provider specialty to work with TGNC clients and 32.1% of websites had no mention of services or resources for TGNC people. Additionally, a significantly larger proportion of intake forms from States with legal protections for TGNC people used affirmative language in gender/sex questions and asked for a client's pronouns than intake forms from States without legal protections. Discussion: Barriers to affirmative healthcare for TGNC people within patient and provider interactions have been identified in previous research and these data show TGNC individuals may face enacted stigma even in their search for a provider, particularly those TGNC people living in States without legal protections.     

“I think you did it!”: Examining the effect of presuming guilt on the verbal output of innocent suspects during brief interviews

Innocent suspects interviewed by a guilt‐presumptive versus innocence‐presumptive or neutral interviewer may tend more to display non‐verbal behaviours which neutral judges consider indicative of guilt. We examined the effects of interviewer's presumption of guilt on innocent mock suspects' alibis. Participants (N = 90) provided an alibi to convince an interviewer of their innocence of a theft after she implied that she believed that they were guilty or innocent or that she had no belief about their veracity. On the basis of existing conflicting findings for suspects' verbal behaviour during accusatory interviews, we predicted that alibis in the guilt‐belief condition would contain the highest or lowest number of correct details with overall higher or poorer accuracy rates, respectively. Although participants perceived the interviewer's presumptive approach, the number of correct details provided and accuracy rates of alibis did not differ significantly between conditions. We propose explanations to these findings and future research paths.     

The new international economic order,basic needs,and technology transfer: Toward an integrated strategy for development in the future

Conceptual premises and objectives underlying the New International Economic Order are reviewed. New perceptions of development, with respect to basic needs of peoples and the transfer and appropriateness of technology are analyzed. An integrated strategy for development is then encouraged, all within the framework of the NIEO.     

Adolescents' Misperceptions of the Dangerousness of Acetaminophen in Overdose

Clinical observations suggest that adolescents commonly and naively use acetaminophen in suicide attempts even when they do not wish to die. It is estimated that 18 500-mg acetaminophen tablets can lead to hepatotoxicity, while death is usually associated with ingestion of 50 or more tablets. A sample comprising 569 adolescent students completed an author-designed survey assessing teenagers' knowledge of acetaminophen's therapeutic and harmful effects. The findings support our original data that adolescents have ready access to acetaminophen and use it in suicide attempts, but underestimate its potential for toxicity. Forty-two percent of this sample underestimated the dose to cause harm, believing it would require 20 or more tablets, and 50% underestimated the dose to cause death, stating 100 or more pills would be necessary. Adolescents appear to seriously underestimate the dangerousness of acetaminophen in overdose, and lack knowledge regarding side effects of overdose.     

Effect of Problem‐Solving Therapy on Depressed Low‐Income Homebound Older Adults' Death/Suicidal Ideation and Hopelessness

Previous study findings of psychotherapy's effect on suicide prevention have been inconsistent. This study reports the results of secondary analyses of outcome data from a short‐term depression treatment on reducing death/suicidal ideation among 158 low‐income homebound adults aged 50+. The treatment, in‐person or telehealth problem‐solving therapy (PST), compared with telephone support call, has been found effective in reducing depressive symptoms and disability among participants. Compared with support call participants, tele‐PST participants, but not in‐person PST participants, exhibited lower ideation ratings across the follow‐up period. Effect sizes at 36 weeks were 0.31 for tele‐PST and 0.17 for in‐person PST. Hopelessness mediated the effect of tele‐PST but not in‐person PST; however, in‐person PST also alleviated hopelessness, which led to lower ideation. Clinical implications of the findings are discussed.
