Landscaping analyses of the ROC predictions of discrete-slots and signal-detection models of visual working memory

A fundamental issue concerning visual working memory is whether its capacity limits are better characterized in terms of a limited number of discrete slots (DSs) or a limited amount of a shared continuous resource. Rouder et al. (2008) found that a mixed-attention, fixed-capacity, DS model provided the best explanation of behavior in a change detection task, outperforming alternative continuous signal detection theory (SDT) models. Here, we extend their analysis in two ways: first, with experiments aimed at better distinguishing between the predictions of the DS and SDT models, and second, using a model-based analysis technique called landscaping, in which the functional-form complexity of the models is taken into account. We find that the balance of evidence supports a DS account of behavior in change detection tasks but that the SDT model is best when the visual displays always consist of the same number of items. In our General Discussion section, we outline, but ultimately reject, a number of potential explanations for the observed pattern of results. We finish by describing future research that is needed to pinpoint the basis for this observed pattern of results.     

Conducting Health Disparities Research with Criminal Justice Populations: Examining Research,Ethics, and Participation

This study explored the challenges of informed consent and understanding of the research process among Black and Latino men under community supervision (e.g., parole and/or probation). Between February and October 2012, we conducted cognitive face-to-face interviews using open-ended questions on the significant areas of research participation (i.e., the informed consent process, confidentiality, compensation, what is meant by human subject and clinical trials) among 259 men aged 35 to 67 under community supervision in Bronx, New York. Content analysis of the open-ended questions revealed limited knowledge concerning the understanding of research participation. The study participants appeared to generally understand concepts such as compensation after research participation and confidentiality. Participants demonstrated a lack of understanding of certain aspects of the research process—informed consent, human subject, Institutional Review Board, and clinical trials. These findings are informative to researchers conducting studies with criminal justice populations and Institutional Review Boards reviewing research studies.     

Intrinsic motivation a key enabler of African managers’ cultural intelligence

This study sought to determine manager's intrinsic motivation to engage multiculturally in the workplace as the managers varied by demographic background. Participants were a convenience sample of managers on supervisory level, middle level and senior level (n=550; Male 54.9%; Black ethnicity 64.4%). They completed the Motivational Scale of the Managerial Cultural Intelligence Measure. The data were analysed by means analysis of variance procedures to determine workforce diversity ability by managerial level and other demographics. The results showed a managerial level effect in that senior managers were significantly more motivated to get information about other cultures in the work group compared to middle managers and supervisors. Supervisors were significantly more willing to change their views of other cultures with learning as compared to senior managers and middle managers. Generally, managers with a shorter employment history are more motivated to engage with multi-cultural groups compared to those with a longer service history. Managers’ motivation to engage multi-culturally would enhance their competence in working with a diverse workforce and thereby embracing true democracy in the workplace.     

For a New Look at ‘Lexical Errors’: Evidence from Semantic Approximations with Verbs in Aphasia

The ability to understand the similarity between two phenomena is fundamental for humans. Designated by the term analogy in psychology, this ability plays a role in the categorization of phenomena in the world and in the organisation of the linguistic system. The use of analogy in language often results in non-standard utterances, particularly in speakers with aphasia. These non-standard utterances are almost always studied in a nominal context and considered as errors. We propose a study of the verbal lexicon and present findings that measure, by an action-video naming task, the importance of verb-based non-standard utterances made by 17 speakers with aphasia (“la dame déshabille l’orange”/the lady undresses the orange, “elle casse la tomate”/she breaks the tomato). The first results we have obtained allow us to consider these type of utterances from a new perspective: we propose to eliminate the label of “error”, suggesting that they may be viewed as semantic approximations based upon a relationship of inter-domain synonymy and are ingrained in the heart of the lexical system.     

Validating an Inventory for the Assessment of Egoistic Bias and Moralistic Bias as Two Separable Components of Social Desirability

The psychometric properties of the German adaptation of the Balanced Inventory of Desirable Responding were investigated. This 2-factor inventory taps the egoistic bias and the moralistic bias as the 2 distinguishable components of social desirability. In 2 validation studies, both subscales showed satisfactory internal consistency and temporal stability. To examine convergent and discriminant validity, the scales were correlated with those of a measure of unrealistic optimism, various measures of self-enhancement, 1-dimensional scales of social desirability, and the tendency to overclaim in a test of general knowledge.     

Shared Affect and Dyadic Synchrony Among Secure and Insecure Parent–Toddler Dyads

The present investigation explored the role of shared affect in parent–child dyadic synchrony during toddlerhood and examined if patterns of dyadic synchrony and shared affect differ for secure and insecure parent–child dyads. Data were collected from 128 families with toddler age children (67 girls and 61 boys) during a laboratory assessment. Mother–toddler and father–toddler interactions were coded for shared positive and negative affect, as well as dyadic synchrony. Attachment status was assessed using the Strange Situation. Data revealed that securely attached parent–toddler dyads spent more time in synchronous interaction, and less time in asynchronous interaction, than insecurely attached parent–toddler dyads. Parent–toddler synchronous interaction among both securely and insecurely attached dyads was characterized by shared positive affect. Among insecure dyads, shared negative affect was more predominate in asynchronous than in synchronous interaction. The role of individual differences in the manifestation of synchronous interaction among securely and insecurely attached parent–toddler dyads is discussed.

Student Perceptions of Sandtray in Solution-Focused Supervision

Sandtray supervision and solution-focused supervision (SFS) are both strengths-based approaches that may be effective in helping counselor trainees reduce their anxiety and develop clinical self-confidence. The purpose of this collective case study was to explore how a group of practicum students with a school counseling emphasis experienced a blending of sandtray and solution-focused supervision (SFS) approaches. Participants described how the blended approach fostered group cohesiveness in their supervision and promoted both personal and professional development. Participants indicated more awareness of the impact of sandtray than the influence of the solution-focused approach in their supervision.     

Fathers' and Mothers' Emotional Accessibility and Youth's Developmental Outcomes

ABSTRACT

This study examined the association between parents' emotional accessibility and youth's functioning. Participants included 154 parents who completed measures of parental emotional accessibility and their children's emotional and behavioral problems. Results showed that mothers are more emotionally accessible to their children. Mothers' emotional accessibility was associated negatively with youth's emotional and behavioral problems; whereas, fathers' emotional accessibility was associated with only youth's behavioral problems. This study highlights the importance of examining parental emotional accessibility when studying youth's development, utilizing parental perceptions to learn about youth and family functioning, and actively including fathers in family research studies.
