Simulated Visual Field Loss Does Not Alter Turning Coordination in Healthy Young Adults

Turning, while walking, is an important component of adaptive locomotion. Current hypotheses regarding the motor control of body segment coordination during turning suggest heavy influence of visual information. The authors aimed to examine whether visual field impairment (central loss or peripheral loss) affects body segment coordination during walking turns in healthy young adults. No significant differences in the onset time of segments or intersegment coordination were observed because of visual field occlusion. These results suggest that healthy young adults can use visual information obtained from central and peripheral visual fields interchangeably, pointing to flexibility of visuomotor control in healthy young adults. Further study in populations with chronic visual impairment and those with turning difficulties are warranted.     

Some conceptual problems involved in the consideration of disorders of narcissism

In a number of different areas of work at the Hampstead Clinic research groups have been concerned with the progressive refinement of psychoanalytic concepts in their application to clinical material. In particular, the procedure of systematic indexing of psychoanalytic case material (Sandler, 1962) and the routine application of Anna Freud's Diagnostic Profile (Anna Freud, 1963), have thrown up problems relating to the conceptual tools at our disposal for the evaluation of what can, broadly speaking, be called “disorders of narcissism”.     

Beyond the Academic Journal: Unfreezing Misconceptions About Mental Illness and Gun Violence Through Knowledge Translation to Decision-Makers

In a policy arena characterized by polarized debate, such as the consideration of legal interventions to prevent gun violence, research evidence is an important tool to inform decision-making processes. However, unless the evidence is communicated to stakeholders who can influence policy decisions, the research will often remain an academic exercise with little practical impact. The Educational Fund to Stop Violence's process of “unfreezing” individual perceptions and conventional interpretations of the relationship between mental illness and gun violence, forming a consensus, and translating this knowledge to stakeholders through state discussion forums is one way to inform policy change. The recent passage of gun violence prevention legislation in California provides an example of successfully closing the knowledge translation gap between research and decision-making processes.

Team adaptation: A fifteen-year synthesis (1998–2013) and framework for how this literature needs to “adapt” going forward

Organizations increasingly operate within dynamic environments that require them to adapt. To respond quickly and effectively to acute or on-going change, many organizations use teams to help them remain competitive. Accordingly, the topic of team adaptation has become more prominent within the broader organizational team literature. Given the wealth of knowledge that has been accumulated, we consider what has been learned to date. However, even with the increased attention to team adaptation within the literature, not all teams are created equal in terms of their capacity for adaptability. Thus, we review factors that serve as antecedents of team adaptation, the process of adaptation, and the resulting adaptive outcomes. Finally, we suggest future directions for research and practice as we introduce a conceptual framework, whereby the focus of a team’s adaptation process is impacted by the type and severity of the disruption or trigger that gives rise to the need for adaptation.     

Phonological processing during silent reading in teenagers who are deaf/hard of hearing: an eye movement investigation

There has been considerable variability within the literature concerning the extent to which deaf/hard of hearing individuals are able to process phonological codes during reading. Two experiments are reported in which participants’ eye movements were recorded as they read sentences containing correctly spelled words (e.g., church), pseudohomophones (e.g., cherch), and spelling controls (e.g., charch). We examined both foveal processing and parafoveal pre‐processing of phonology for three participant groups—teenagers with permanent childhood hearing loss (PCHL), chronological age‐matched controls, and reading age‐matched controls. The teenagers with PCHL showed a pseudohomophone advantage from both directly fixated words and parafoveal preview, similar to their hearing peers. These data provide strong evidence for phonological recoding during silent reading in teenagers with PCHL.     

Object specificity and personal relevance in long-term visual remembering

The personal relevance of an object is multi-faceted, each facet being capable of contributing to the effects on object memory attributed to personal relevance. An object's status as an individual object (object specificity), rather than just a category of object, is one such facet and its impact on the long-term visual remembering of everyday objects is assessed in two experiments. Images and drawings were produced under generic (e.g., “Please draw a bed”) and personal exemplar (e.g., “Please draw your bed”) instructions, and participants indicated the degree to which the image on which their drawing was based was of a specific object or a generic object. Object specificity induced a sense of time and place for a remembered object, the most recent encounter with the object being most salient. Other aspects of personal relevance collectively facilitated the retrieval of an object's category-irrelevant features (thereby increasing the vividness of the object image), the other objects with which it was seen, and a more general episodic sense of place. Against a broader theoretical perspective, it is proposed that visual episodic memory and visual knowledge are primary sources of information for specific personally relevant objects and generic objects, respectively.     

Examining adversarial growth in illness: The factor structure of the silver lining questionnaire (SLQ-38)

The Silver Lining Questionnaire (SLQ-38) is purported to measure 10 aspects of adversarial growth in illness. To date however, no empirical evidence exists to support this claim. Hence the aim of this study was to investigate the factor structure of the SLQ-38 in a sample of 560 individuals with multiple sclerosis (MS), cancer, cardiac, and renal disease. The results demonstrate that 24 SLQ-38 items can be factored into five subscales: improved personal relationships, greater appreciation for life, positive influence on others, personal inner strength and changes in life philosophy, all of which are in accordance with the literature on adversarial growth. Individuals with MS experienced lower adversarial growth compared to other illness groups. Gender, age and time since diagnosis were unrelated to adversarial growth in illness. The utility of the revised SLQ-38 is discussed along with suggestions for future research on the convergent and divergent validity of this revised instrument.     

Emotion recognition of static and dynamic faces in autism spectrum disorder

There is substantial evidence for facial emotion recognition (FER) deficits in autism spectrum disorder (ASD). The extent of this impairment, however, remains unclear, and there is some suggestion that clinical groups might benefit from the use of dynamic rather than static images. High-functioning individuals with ASD (n = 36) and typically developing controls (n = 36) completed a computerised FER task involving static and dynamic expressions of the six basic emotions. The ASD group showed poorer overall performance in identifying anger and disgust and were disadvantaged by dynamic (relative to static) stimuli when presented with sad expressions. Among both groups, however, dynamic stimuli appeared to improve recognition of anger. This research provides further evidence of specific impairment in the recognition of negative emotions in ASD, but argues against any broad advantages associated with the use of dynamic displays.     

Intellectual, behavioral, and personality correlates of violent vs. non-violent juvenile offenders

The overall aim of this study was to examine the relationship between offender status (violent vs. nonviolent) and selected predictor variables from personality, behavioral, and intellectual domains. The two main sub goals were (a) to determine which variables from these domains were most closely associated with offender status, and (b) to construct a stepwise logistic regression model that could help identify which juveniles were more likely to be incarcerated for violent vs. nonviolent offenses. The participants for this investigation were juvenile offenders referred to the Juvenile Court Assessment Center by the Juvenile Justice Division of the Eleventh Judicial Circuit. The court-ordered assessment included the following measures: (a) The Millon Adolescent Clinical Inventory (MACI), (b) the Behavior Assessment System for Children (BASC), (c) the Peabody Picture Vocabulary Test-Third Edition (PPVT-III), (d) the Wide Range Achievement Test-Third Edition (WRAT-III), (e) the Kaufman Brief Intelligence Test (K-BIT), and (f) records of school achievement. The ten variables that had the strongest association with offender status were entered into the stepwise logistic regression analysis; five of these strategically chosen predictor variables accurately differentiated violent from nonviolent offenders 86.3% of the time. Reading Percentile (β=-.051), PPVT-III (β=-.059), MACI-Inhibition (β=-.033), MACI-Eating Dysfunction (β=.051), and BASC-Sense of Inadequacy (β=-.072). Gender differences were explored.     

Influences of APOE ε4 and expertise on performance of older pilots

Little is known about how APOE ε4-related differences in cognitive performance translate to real-life performance, where training and experience may help to sustain performance. We investigated the influences of APOE ε4 status, expertise (FAA pilot proficiency ratings), and their interaction on longitudinal flight simulator performance. Over a 2-year period, 139 pilots aged 42-69 years were tested annually. APOE ε4 carriers had lower memory performance than noncarriers (p = .019). APOE interacted with Expertise (p = .036), such that the beneficial influence of expertise (p = .013) on longitudinal flight simulator performance was more pronounced for ε4 carriers. Results suggest that relevant training and activity may help sustain middle-aged and older adults' real-world performance, especially among APOE ε4 carriers.
