Market mavenism and consumer self‐confidence

• The purpose of this study was to test hypothesized associations between market mavenism and consumer self‐confidence (CSC). A survey of 190 US consumers provided the data. The results showed significant relationships between mavenism and several dimensions of CSC, and regression analysis emphasized the relationships with two of these: information acquisition (confidence in the ability to obtain and use marketplace information) and social outcomes decision making (confidence in obtaining positive reactions from others). These findings both enrich our knowledge of the psychology of market mavenism by suggesting some motivations for these behaviors and suggest marketing strategies can be fine‐tuned to appeal more effectively to this important segment of consumers.

Visuomotor tracking abilities of speakers with apraxia of speech or conduction aphasia

This investigation examined the visuomotor tracking abilities of persons with apraxia of speech (AOS) or conduction aphasia (CA). In addition, tracking performance was correlated with perceptual judgments of speech accuracy. Five individuals with AOS and four with CA served as participants, as well as an equal number of healthy controls matched by age and gender. Participants tracked predictable (sinusoidal) and unpredictable signals using jaw and lip movements transduced with strain gauges. Tracking performance in participants with AOS was poorest for predictable signals, with decreased kinematic measures of cross-correlation and gain ratio and increased target-tracker difference. In contrast, tracking of the unpredictable signal by participants with AOS was performed as well as for other groups (e.g. participants with CA, healthy controls). Performance of the subjects with AOS on the predictable tracking task was found to strongly correlate with perceptual judgments of speech. These findings suggest that motor control capabilities are impaired in AOS, but not in CA. Results suggest that AOS has its basis in motor programming deficits, not impaired motor execution.     

Multi-limb coordination and rhythmic variability under varying sensory availability conditions in children with DCD

Children with Developmental Coordination Disorder (DCD) have sensory processing deficits; how do these influence the interface between sensory input and motor performance? Previously, we found that children with DCD were less able to organize and maintain a gross motor coordination task in time to an auditory cue, particularly at higher frequencies [Whitall, J., Getchell, N., McMenamin, S., Horn, C., Wilms-Floet, A., & Clark, J. (2006). Perception-action coupling in children with and without DCD: Frequency locking between task relevant auditory signals and motor responses in a dual motor task. Child: Care, Health, and Development, 32, 679-692]. In the present study, we examine the same task (clapping in-phase to marching on a platform) under conditions involving the removal of vision and hearing. Eleven children with DCD (mean=7.21, SD=0.52 years), 7 typically developing (TD) children (mean=6.95+/-0.72 years), and 10 adults performed continuous clapping while marching under four conditions: with vision and hearing, without vision, without hearing, and without both. Results showed no significant condition effects for any measure taken. The DCD group was more variable in phasing their claps and footfalls than both the adult group and the TD group. There were also significant group effects for inter-clap interval coefficient of variation and inter-footfall interval coefficient of variation, with the DCD group being the most variable for both measures. Coherence analysis between limb combinations (e.g., left arm-right arm, right arm-left leg) revealed that the adults exhibited significantly greater coherence for each combination than both of the children's groups. The TD group showed significantly greater coherence than the DCD group for every limb combination except foot-foot and left hand-right foot. Measures of approximate entropy indicated that adults differed from children both with and without DCD in the structure of the variability across a trial with adults showing more complexity. Children with DCD are able to accomplish a self-initiated gross-motor coordination task but with increased variability for most but not all measures compared to typically developing children. The availability of visual and/or auditory information does not play a significant role in stabilizing temporal coordination of this task, suggesting that these are not salient sources of information for this particular task.     

Structures of Personality and Their Relevance to Psychopathology: II. Further Articulation of a Comprehensive Unified Trait Structure

ABSTRACT There is increasing agreement that the current categorical system of personality disorders (PDs) in the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM‐IV; American Psychiatric Association, 2000) should be replaced by a trait dimensional scheme in DSM‐V. In particular, the consensus appears to be converging on a hierarchical Big Four model. The broad factors that form the apex of this hierarchy are essentially maladaptive variants of the Big Five traits of normal personality, minus Openness. We argue that this Big Four model is incomplete, however, in that it fails to model characteristics related to the “odd or eccentric” Cluster A PDs adequately. We report the results of three studies that examine these odd, eccentric characteristics in relation to basic dimensions of normal and abnormal personality. The results of these studies establish the existence of an Oddity factor that is (a) broader than the Cluster A traits and (b) distinct from Openness and the other Big Five dimensions. Consequently, its addition yields an alternative five‐factor model of personality pathology (considering only abnormal traits) and an expanded, integrated Big Six taxonomy that subsumes both normal and abnormal personality characteristics.     

Continuous and discontinuous drawing: high temporal variability exists only in discontinuous circling in young children

The authors studied whether the drawing variability in young children is best explicable by (a) demands on the explicit timing system, (b) an underdeveloped ability to control limb dynamics, or (c) both. The explicit timing demands were lower in continuous drawing in comparison with the discontinuous task. The authors manipulated limb dynamics by changing the number of joints involved, with line drawing requiring fewer joints than circle drawing. Results showed that young children had high temporal variability in discontinuous circling but not in other conditions. The authors argue that both explicit timing and dynamic complexity of limb control may be determinants of temporal consistency and may thus play an important role in the development of drawing and writing skills in children.     

"Walking on eggshells": how expressing relationship insecurities perpetuates them

The authors present a model positing that when people are insecure about a relationship partner's acceptance, they often express emotional vulnerabilities to the partner, which causes them to believe the partner views them as highly vulnerable and insecure. In turn, this belief causes them to doubt the authenticity of the partner's expressions of positive regard, which may perpetuate the experience and expression of insecurity that initiated the process. Prototypes of interactions with interpersonally vulnerable individuals included partners' inauthentic expressions of regard (Study 1). Suggesting that these prototypes are applied to personal relationships when vulnerabilities are expressed, those who claimed to have expressed vulnerabilities doubted the partner's authenticity because they believed that they were viewed as vulnerable (Studies 2A, 2B, and 4). Authenticity doubts in turn predicted perceptions of rejection (Studies 3 and 4), which in turn predicted partner derogation and subsequent expressions of vulnerability (Study 4). An experimental manipulation of reflected appraisals of vulnerability increased doubts about the authenticity of a new acquaintance's expressions of emotion (Study 5). Relational insecurity may be perpetuated via the intrapersonal cognitive consequences of expressing it.     

Counselling Australian baby boomers: examining the loss and grief issues facing aging distance-separated sibling dyads

It has long been recognised that mature-aged sibling dyads provide each other with emotional support. What has yet to be determined is whether this support function is maintained within the baby boomer generational cohort of sibling dyads who through economic relocation/migration have become separated by distance. As such, this paper highlights the need for research to be conducted into the experiences of baby boomers dealing with sibling loss and grief-related issues without the support of their nuclear and extended family members.     

Teleconferencing model for forensic consultation, court testimony, and continuing education

A medical center-based forensic clinic that provides the necessary comprehensive consultation, continuing education, court testimony, and clinical services through an applied model of teleconferencing applications is addressed. Telemedicine technology and services have gained the attention of both legal and clinical practitioners, examining trends and models of health care for underserved populations, and identifying where consultation with a team of professionals may benefit service providers in rural communities. The contribution offered herein provides an understanding of the history of the development of the clinic, a theoretical model that has been applied to a clinical forensic program that employs telepsychiatry services, and the ethical and malpractice liability issues confronted in using teleconferencing services. This model is examined through a child and adolescent forensic evaluation clinic. The goals of this model are offered, as are a number of applications within the broad spectrum of services utilizing telemedicine. Finally, changing patterns are addressed in clinically based health-care delivery for criminal justice, social services, and forensic mental health.
