Mechanisms of Reference Frame Selection in Spatial Term Use: Computational and Empirical Studies

Previous studies have shown that multiple reference frames are available and compete for selection during the use of spatial terms such as “above.” However, the mechanisms that underlie the selection process are poorly understood. In the current paper we present two experiments and a comparison of three computational models of selection to shed further light on the nature of reference frame selection. The three models are drawn from different areas of human cognition, and we assess whether they may be applied to a reference frame selection by examining their ability to account for both existing and new empirical data comprising acceptance rates, response times, and response time distributions. These three models are the competitive shunting model (Schultheis, 2009 ), the leaky competing accumulator (LCA) model (Usher & McClelland, 2001 ), and a lexical selection model (Howard, Nickels, Coltheart, & Cole‐Virtue, 2006 ). Model simulations show that only the LCA model satisfactorily accounts for the empirical observations. The key properties of this model that seem to drive its success are its bounded linear activation function, its number and type of processing stages, and its use of decay. Uncovering these critical properties has important implications for our understanding not only of spatial term use, in particular, but also of conflict and selection in human cognition more generally.     

Facilitating Informed Consent: A Multicultural Perspective

Respect for the dignity and autonomy of patients has long been a fundamental principle of ethical decision making. As a practical matter, a primary way of maintaining this ethical standard is by obtaining an individual’s informed consent prior to intervening or collecting data. By giving individuals clear information about alternative treatments and potential risks and benefits, the practitioner tries to ensure that the patient can make an informed choice. However, there are cases in which those seeking informed consent have very different values and belief systems from those whose consent is being sought. In this article we explore such discrepancies using informed consent with Navajo clients as an example, illustrate potential challenges with case examples, and propose ways in which ethical dilemmas may be successfully navigated.     

An Open Trial Targeting Food Cue Reactivity and Satiety Sensitivity in Overweight and Obese Binge Eaters

Data suggests that individuals who binge eat are more responsive to food cues in the environment and less sensitive to satiety cues. The aim of this open trial was to evaluate the feasibility, acceptability, and initial effectiveness of a novel treatment grounded in Schachter’s externality theory targeting food cue reactivity and satiety responsiveness with obese adults who binge eat. Treatment was provided in groups, and utilized appetite monitoring, cue-exposure treatment, in vivo exercises, self-monitoring, and coping skills. Twenty-eight overweight and obese adults who binge eat (82% female; mean age = 47.5 years [SD = 12.8]; BMI = 38.9 [SD = 10.3]; 79% White non-Hispanic) participated in a 4-month group-based treatment program. Assessments were conducted at baseline, posttreatment, and 3-month follow-up time points. Results indicated that this treatment was well accepted and had high retention at posttreatment. Initial effectiveness showed significant decreases in BMI, and improvements in loss of control and overeating episodes, food responsiveness, and power of food. The majority of results were maintained at the 3-month follow-up time point. This open trial provides preliminary evidence for the feasibility, acceptability, and initial effectiveness of this treatment on both eating disorder symptoms and weight in obese adults who binge eat. Because these data are preliminary, further treatment development and randomized controlled studies are needed.     

Relationships between self-determination theory and theory of planned behavior applied to physical activity and exercise behavior in chronic pain

This study examined the relationships between self-determination theory (SDT) and theory of planned behavior (TpB) applied to physical activity and exercise behavior (PA&E) in people with chronic pain. Two hundred and eleven adults with chronic musculoskeletal pain (28 males and 183 females, age range 18 to 82 years, mean age 43 years) were recruited from online support groups and clinic networks in the United States. Participants completed SDT measures relevant to PA&E on perceived autonomy support, autonomy, competence, and relatedness, as well as TpB measures relevant to PA&E on intention, attitudes, subjective norms, and perceived behavioral control. Correlational techniques and canonical correlation analysis were performed to examine the relationships and variance within and between theoretical dimensions. Overall, the SDT set accounted for 37% of the TpB variance and the TpB set accounted for 32% of the SDT set variance. The results indicate there are statistical similarities and differences between concepts in SDT and TpB models for PA&E. Using both empirical guidance and clinical expertise, researchers and practitioners should attempt to select and integrate non-redundant and complementary components from SDT, TpB, and other related health behavior theories.     

Dynamic accountability in clinical training and supervision: Three orienting ideals

Despite the growing interest on making clinical practice accountable, research on how specific components of professional competence are relevant in actual training/supervision practice is as yet unspecified. This study explores this dynamic aspect of professional supervision. Three supervisory dyads, composed by an experienced supervisor and a doctoral counseling psychology student were used in the study. A qualitative, ethnomethodology-informed design was used to discursively analyze 16 significant episodes (SEs) in actual supervision meetings. This was complemented by 16 follow-up interviews. Three interpretative repertoires – ‘ideals’ – influencing participants’ accounting practices were identified: efficacy, responsiveness, and authenticity. The article discusses how structural (competency-based) and dynamic (practice-based) approaches to accountability can be combined to guide the appraisal of relevant professional competencies.     

Reward Priority of Visual Target Singletons Modulates Event-Related Potential Signatures of Attentional Selection

ABSTRACT— We examined visual search for color singleton targets, whose shape was discriminated. Critically, we varied the reward priority of singleton colors (correct fast performance was worth more bonus points for red singletons than for green singletons, or vice versa) to test whether event-related potential signatures of visual selection can be affected by distinct reward priorities for different target types, even when every target has to be selected for report. The N2pc component was earlier and larger for high- than for low-reward targets. This influence of reward on the N2pc correlated with the subject-by-subject impact of reward level on efficiency of behavioral performance. Later postselection processing was also affected by reward level. These results demonstrate that visual selection of task-relevant items is rapidly modulated by reward-related priorities, even when every target has to be selected for response.     

Career transitions and their causes: A country‐comparative perspective

This empirical paper investigates how individuals conceptualize causes of career transitions, focusing on the three European countries of Austria, Serbia, and Spain in comparison to the USA and China. Collectively, these countries represent four separate cultural regions according to Schwartz. Semi‐structured interviews were conducted with members of three occupational groups: business people, nurses, and blue‐collar workers. Analysis of the data generates greater insight about the existence of both region‐specific patterns as well as potentially universalistic tendencies regarding perceived causes of career transitions. Perceptions of internal (to the person) drivers of career transitions as activating forces are evident in all five countries. The overall results support contemporary notions of occupational careers that are highly individualized, a characterization strongly emphasized in the current career literature. In the European culture clusters, causes of career transitions are attributed internally and externally. China, representing the Confucian cultural region, stresses external causes for career transitions. By contrast, in the USA only internal attributions of causes are reported.     

Physical Action Without Interaction

In “Action without interaction” (2005) I showed that one might act on a physical system (there, a particle), without interacting with it, by the procedure of making it disappear. This paper presents further extensions and a critique of that result. These extensions show why physical actions without interaction are possible, while underscoring the philosophical fertility of a characteristic approach to the actual infinite inaugurated by Benardete.
