Colour matching of isoluminant samples and backgrounds: a model

A cone-opponent-based vector model is used to derive the activity in the red-green, yellow-blue, and achromatic channels during a sequential asymmetric colour-matching experiment. Forty Munsell samples, simulated under illuminant C, were matched with their appearance under eight test illuminants. The test samples and backgrounds were photometrically isoluminant with each other. According to the model, the orthogonality of the channels is revealed when test illuminants lie along either red-green or yellow blue cardinal axes. The red green and yellow-blue outputs of the channels are described in terms of the hue of the sample. The fact that the three-channel model explains the data in a colour-matching experiment indicates that an early form of colour processing is mediated at a site where the three channels converge, probably the input layer of V1.     

Personality and job performance: test of the mediating effects of motivation among sales representatives

Research shows consistent relations between personality and job performance. In this study the authors develop and test a model of job performance that examines the mediating effects of cognitive-motivational work orientations on the relationships between personality traits and performance in a sales job (N = 164). Covariance structural analyses revealed proximal motivational variables to be influential mechanisms through which distal personality traits affect job performance. Specifically, striving for status and accomplishment mediate the effects of Extraversion and Conscientiousness on ratings of sales performance. Although Agreeableness was related to striving for communion, neither Agreeableness nor communion striving was related to success in this sales job. The importance of the proposed motivational orientations model is discussed.     

Youth Mental Illness and the Family: Parents’ Loss and Grief

Parents and family members whose adult child or relative has a mental illness endure significant losses, to which they respond with grief. Such grief may negatively affect family members’ physical and psychological health and also the relationship with their relative. Yet, research in this field is sparse. Very few studies have examined parents’ loss and grief in the context of the patient being a child or teen. It is not clear the extent to which parents’ loss and grief in response to their child or adolescent’s mental illness is similar or different to the accounts of older parents and family members caring for an adult relative with major psychopathology (e.g., Schizophrenia, Bipolar disorder). Parental loss and grief is not often addressed in child and adolescent mental health services’ provision of care; alarmingly, little is known about how best to support parents who access these services. The present study aimed to bridge this knowledge gap and identify the therapeutic needs of this younger parent population. Comprehensive interviews were conducted with 14 parents and one custodial grandparent of a youth aged 18 years or younger who was currently attending a child and adolescent mental health service. An inductive thematic analysis identified six themes; parents’ narrative of finding out, profound and pervasive loss, complex grief, waning support, the challenges of caregiving and a call for assistance. It can be inferred from these results that youth mental illness can constitute a source of loss and grief for parents. Participants’ loss and grief was largely consistent with the experience of families caring for an adult relative with major psychopathology. Opportunities for mental health practitioners to support families’ loss and grief were identified. Further studies are needed to enhance understanding of this complex and, to a large extent, ignored familial experience. Results do underscore the importance of clinicians acknowledging parents’ loss and grief and working directly with this experience over the course of youths’ treatment, perhaps in conjunction with family psychoeducation approaches.     

Maternal Emotional Distress,Abuse Risk,and Children's Symptoms: Child Gender as a Moderator of Parent Sensitivity as a Mediator

Mothers' distress is a correlate of their children's elevated behaviour problems and symptoms. Parenting practices have been shown to mediate these associations, but few studies have observed parenting or focused on parents at risk of child abuse. In this study of 269 high‐risk mothers and their young children (M = 4.2 years), structural equation modelling was used to test associations between mothers' distress and child externalizing and internalizing symptoms. Associations were expected to be partly indirect via mothers' observed low sensitivity, and child gender was expected to moderate associations. Also, mothers' child abuse risk was examined as a unique correlate of sensitivity and children's symptoms, and a moderator of associations of distress with sensitivity and symptoms. Associations showed a pattern of gender‐moderated mediation with the link between mothers' distress and internalizing mostly direct for boys, and equally direct and indirect via sensitivity for girls. The association of mothers' distress with externalizing was mostly direct for boys and girls. Mothers' child abuse risk was not uniquely associated with sensitivity or symptoms and did not moderate any associations. There were no differences in model paths between mothers referred from child welfare/mental health compared with other sources or self‐referred. Copyright © 2013 John Wiley & Sons, Ltd.     

Assessing Individual Differences: Effects of Responding to Prior Questionnaires on the Substantive and Psychometric Properties of Self-Esteem and Depression Assessments

It has become a common practice among psychological researchers to administer batteries of individual difference assessments to research participants, although little is known about whether the substantive and psychometric integrity of the questionnaires are maintained when they are administered after the subject has completed other instruments. The studies presented here consider these issues in relation to the assessment of self-esteem and depression. In the first study, college students responsed to a self-esteem inventory (a) by itself (control group), (b) after one prior questionnaire, (c) after three prior questionnaires, or (d) after five prior questionnaires. Results indicated that filling out one or more questionnaires before an assessment of self-esteem resulted in repots of lower self-esteem relative to the control condition. Additional analyses revealed that filling out three or five prior questionnaires created lower reliabilities of subscale scores and lower estimates of concurrent validity between self-esteem and depression. When the effect of prior questionnaires on the General Self-Esteem subscale was examined, the aforementioned results were replicated, and the prior questionnaire treatment created heterogeneous variances across the experimental groups. The second study was designed as a replication of the first study, using an assessment of depression as the target questionnaire. These results revealed that reports of depressive symptomatology increased as the number of prior questionnaires increased. Again, the prior or questionnaire treatment created heterogeneity of variance between the groups, but did not adversely affect its internal consistency.     

The Rorschach Index of Repressive Style and Scale Checking Style: A Study of Sex Differences

Males and females, subdivided into contrasting groups on the Rorschach Index of Repressive Style (RIRS), completed semantic differentials using themselves and their own art productions as the objects rated. Analysis was made of the relationship between sex and verbal style, and a scale checking style (use of end points versus use of intermediate points) believed to reflect a dimension of rapid, extreme decisions versus careful consideration of nuances. Results showed that males characterized by rich and fluid verbal processes tended toward cautious ratings (use of intermediate points) while females who were verbally free exhibited more extreme ratings (use of end points). It is concluded that a test variable may have different predictive significance in males and females, even though there is no sex difference in the magnitudes of the variables involved. There may be sex differences in the organization of cognitive processes.     

Suggestion for Gaining Rapport with Children who Appear Resistant to Testing

A story-drawing technique designed to gain rapport with children who appear resistant to testing is described. The technique involves the child with the examiner in a question answering procedure around the development of a picture the examiner draws for the child. The drawing has intrinsic interest, permitting the examiner to shape the set of responding to questions in an enjoyable, non-evaluative setting prior to the introduction of test materials. The drawing, requiring no artistic skill on the part of the examiner, is suitable for children up to about eight or nine years of age.     

Pine ridge places—Feral,liminal, sacred

Animal dreams can bring us into deeper relationship with our own instinctual nature. They seem to communicate something from the ancient vestiges of our functioning on earth—all the head knowledge in the world cannot match the sheer vibrancy and power of our own animal. In an age characterized by alienation from the rhythms of natural life, animal dreams can remind us that we still retain access to the deepest layers of instinctual wisdom. This is particularly relevant for women, as they tend to suffer the consequences of an overly technological society most keenly. Women's lives are anchored in natural rhythms, and the impact of living in a culture that ignores and denigrates nature is therefore especially wounding. This essay explores the ways in which dreams of animals can help guide women back toward a relationship with their embodied nature. The author researches and explores several examples of animals in women's dreams and the ways in which these dreams can support a return to what is most vital and “natural” in their lives.
