Does a sensory processing deficit explain counting accuracy on rapid visual sequencing tasks in adults with and without dyslexia?

The experiments conducted aimed to investigate whether reduced accuracy when counting stimuli presented in rapid temporal sequence in adults with dyslexia could be explained by a sensory processing deficit, a general slowing in processing speed or difficulties shifting attention between stimuli. To achieve these aims, the influence of the inter-stimulus interval (ISI), stimulus duration, and sequence length were evaluated in two experiments. In the first that used skilled readers only, significantly more errors were found with presentation of long sequences when the ISI or stimulus durations were short. Experiment 2 used a wider range of ISIs and stimulus durations. Compared to skilled readers, a group with dyslexia had reduced accuracy on two-stimulus sequences when the ISI was short, but not when the ISI was long. Although reduced accuracy was found on all short and long sequences by the group with dyslexia, when performance on two-stimulus sequences was used as an index of sensory processing efficiency and controlled, group differences were found with presentation of stimuli of short duration only. We concluded that continuous, repetitive stimulation to the same visual area can produce a capacity limitation on rapid counting tasks in all readers when the ISIs or stimulus durations are short. While reduced accuracy on rapid sequential counting tasks can be explained by a sensory processing deficit when the stimulus duration is long, slower processing speed in the group with dyslexia explains the greater inaccuracy found as sequence length is increased when the stimulus duration is short.     

A Sequential Examination of Parent–Child Interactions at Anesthetic Induction

Parental presence is often employed to alleviate distress in children within the context of surgery under general anesthesia. The critical component of this intervention may not be the presence of the parent per se, but more importantly the behaviors in which the parent and child engage when the parent is present. The purpose of the current study was to examine the sequential and reciprocal relationships between parental behaviors and child distress during induction of general anesthesia. Participants were 32 children (3–6 years) receiving dental surgery as a day surgery procedure, and their parents. A modified Child Adult Medical Procedures Interaction Scale-Revised was used to code parent and child behaviors. Initial child distress led to increased parental provision of reassurance and decreased provision of physical comfort. Our findings may inform the development of preoperative preparation programs whereby parents can be appropriately educated about what behaviors will be helpful/unhelpful for their child during induction of general anesthesia.     

Global coherence in younger and older adults: Influence of cognitive processes and discourse type

The purpose of the present research was to examine the influence of cognitive processes on discourse global coherence ability measured across different discourse tasks and collected from younger (n = 40; 20–39 years) and older (n = 40; 70–87 years) cognitively healthy adults. Study participants produced oral language samples in response to five commonly used discourse elicitation tasks and they were analyzed for maintenance of global coherence. Participants also completed memory and attention measures. Group differences on the global coherence scale were found for only one type of discourse—recounts. Across discourse elicitation tasks the lowest global coherence scores were found for recounts compared to the other discourse elicitation tasks. The influence of cognitive processes on maintenance of global coherence differed for the two age groups. For the younger group, there were no observed significant relationships. For the older group, cognitive measures were related to global coherence of stories and procedures.     

A critical review of relationship quality measures: Is a fresh start needed? An agenda to move forward

Social relationships in and around work are a fundamental building block of organizational life. According to a number of relationship theories, the quality of those relationships is a critical aspect of their influence on a variety of employee and organizational outcomes. Relationship quality is, therefore, one of the most commonly studied constructs in management research. Our paper critically reviews the landscape of relationship quality measures used in management studies, identifying critical issues with how the construct has been conceptualized and measured. To help advance research on the subject and improve measurement, we identify and evaluate 21 relationship quality measures that have been developed for, or used in, management research. Overall, we find that the instruments used to measure relationship quality in management research have significant limitations associated with their conceptualizations and operationalizations. Many of these limitations stem from the fact that most of the measures used to assess the construct were not originally designed to measure relationship quality, which impedes research clarity and implications. We offer a future research agenda and several recommendations for the advancement of management research on relationship quality.     

Honoring Protective Responses: Reframing Resistance in Therapy Using Polyvagal Theory

Therapists often conceptualize resistance as client behaviors that impede progress; this perspective threatens the therapeutic alliance, especially in couple and family therapy where increased resistance and multiple alliances are present. Polyvagal theory reframes and normalizes resistant behaviors as preconscious, protective responses emerging from our autonomic nervous system. The theory also explains how humans reciprocate safety cues to connect with each other; therapists can use concepts of polyvagal theory to manage their own emotional regulation and foster safety and connection in therapy. Polyvagal concepts deepen our understanding of protective behaviors presenting in couple and family therapy; therapists can help couple and family clients to recognize protective behaviors in their own relationships and facilitate safer connection and engagement. Clinical implications are presented: psychoeducation can help clients normalize and understand their protective processes; therapist presence and immediacy acknowledges and normalizes protective behaviors as they arise; therapist and client self-regulation skills support connection; therapist genuineness is a precondition to client safety; and understanding of polyvagal theory enhances assessment of conflict and enactments in couple and family therapy.

Stress in telephone helpline nurses is associated with failures of concentration,attention and memory,and with more conservative referral decisions

Nurses working for telephone‐based medical helplines must maintain attentional focus while quickly and accurately processing information given by callers to make safe and appropriate treatment decisions. In this study, both higher levels of general occupational stress and elevated stress levels on particular shifts were associated with more frequent failures of attention, memory, and concentration in telephone nurses. Exposure to a stressful shift was also associated with a measurable increase in objectively assessed information‐processing errors. Nurses who experienced more frequent cognitive failures at work made more conservative decisions, tending to refer patients on to other health professionals more often than other nurses. As stress is associated with cognitive performance decrements in telephone nursing, stress‐reduction interventions could improve the quality and safety of care that callers to medical helplines receive.     

Mixture Modeling Methods for the Assessment of Normal and Abnormal Personality,Part I: Cross-Sectional Models

Over the past 75 years, the study of personality and personality disorders has been informed considerably by an impressive array of psychometric instruments. Many of these tests draw on the perspective that personality features can be conceptualized in terms of latent traits that vary dimensionally across the population. A purely trait-oriented approach to personality, however, might overlook heterogeneity that is related to similarities among subgroups of people. This article describes how factor mixture modeling (FMM), which incorporates both categories and dimensions, can be used to represent person-oriented and trait-oriented variability in the latent structure of personality. We provide an overview of different forms of FMM that vary in the degree to which they emphasize trait- versus person-oriented variability. We also provide practical guidelines for applying FMM to personality data, and we illustrate model fitting and interpretation using an empirical analysis of general personality dysfunction.     

Introduction to the Special Section on Mixture Modeling in Personality Assessment

Latent variable models offer a conceptual and statistical framework for evaluating the underlying structure of psychological constructs, including personality and psychopathology. Complex structures that combine or compare categorical and dimensional latent variables can be accommodated using mixture modeling approaches, which provide a powerful framework for testing nuanced theories about psychological structure. This special series includes introductory primers on cross-sectional and longitudinal mixture modeling, in addition to empirical examples applying these techniques to real-world data collected in clinical settings. This group of articles is designed to introduce personality assessment scientists and practitioners to a general latent variable framework that we hope will stimulate new research and application of mixture models to the assessment of personality and its pathology.
