Color discrimination on Mangaia

Bornstein’s hypothesis that there is a loss of color discrimination in tropical areas was not supported in earlier research in the Cook Islands. Using a more sensitive color vision test (the Farnsworth-Munsell 100-Hue Test), a loss of color discrimination in the red-purple and blue-green regions of the spectrum was found. The lack of sex differences in this color discrimination loss supports a physiological rather than a genetic explanation of the observed decrement.     

Evaluation of the relative effectiveness of methylphenidate and cognitive behavior modification in the treatment of kindergarten-aged hyperactive children

This study of kindergarten-aged hyperactive children evaluated the effects of three modes of treatment in relation to an untreated control group. The treatments were administered over a 3-month period and included cognitive behavior modification, methylphenidate, and the two treatments combined. A follow-up assessment was done approximately 1 year later at the end of the first grade. Analyses of psychological, rating scale observational, and interview data showed that hyperactive children became less symptomatic over time;the data did not provide evidence indicating that any of the treatments studied was more effective than any other or than no treatment at all.This research was supported by grants from the Ontario Mental Health Foundation (Grant No. 701-76/78) and The Hospital for Sick Children Foundation (Grant No. 77-22). The authors wish to thank Mr. Syl Sauro, of the Etobicoke Board of Education, and Mrs. M. Stijovic, of the Etobicoke Community Health Department, for their cooperation.     

Promoting parent–infant responsiveness in families experiencing homelessness

My Baby's First Teacher is an intervention designed specifically for parents with infants staying in emergency homeless shelters. Infants are overrepresented in shelter populations and face considerable risk to their development, including mental health. We utilized a randomized controlled design across three family shelters to evaluate the program's effectiveness with 24 dyads assigned to the intervention compared to 21 dyads in care-as-usual. Dyads were randomized by round at each site to account for shelter effects. We used path analysis to illustrate change over time and in relation to intervention assignment.     

Subfactors of DSM-IV Conduct Disorder: Evidence and Connections with Syndromes from the Child Behavior Checklist

Is conduct disorder (CD) as defined in the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV; American Psychiatric Association, 1994) a unitary entity, or do variants of CD exist? We addressed this question, using data collected from the parents of 1,669 Australian boys, aged 6–17. Parents were interviewed to assess DSM-IV Conduct Disorder (DSM-IV CD) criteria. Results revealed 2 subfactors of DSM-IV CD symptoms, made up of overt behaviors (e.g., initiating physical fights) and covert behaviors (e.g., stealing without confrontation). Ordinary least squares regressions showed the 2 CD subfactors to be significantly and uniquely predicted by Child Behavior Checklist (CBCL; T. M. Achenbach, 1991a, 1991b) syndromes labeled Aggressive Behavior and Delinquent Behavior, respectively. The results are discussed in terms of the utility of differentiating these 2 variants of CD in future editions of the DSM.     

Psychologists' and counsellors' perspectives on prolonged grief disorder and its inclusion in diagnostic manuals

Introduction: In this research, proposed criteria for what has been termed ‘Prolonged Grief Disorder’ (PGD) (more recently termed, ‘Persistent Complex Bereavement‐Related Disorder’ (PCB‐RD) in the proposed DSM‐V), were presented to psychologists and counsellors. Method: Participants were asked about their views on the ‘disorder’ and whether they considered its inclusion in diagnostic manuals was justified. A total of 185 participants, (147 psychologists, specialist and general, and 38 counsellors) responded to an online survey (part of a larger research project), concerning their attitudes, choices and activities regarding bereavement therapy. In this part of the research, therapists’ perspectives about pathological grief, the recognition of PGD and its inclusion in diagnostic manuals were explored. Fifty‐nine participants took the option of adding written remarks to the survey to expand on their opinions regarding PGD. Results/Conclusions: Tentative support for the inclusion of PGD in diagnostic manuals was given; however many therapists indicated considerable reservations about potential negative repercussions of using such a diagnosis. One‐way between‐groups analysis of variance was undertaken to determine whether participants' opinions varied according to main occupation or specialism; however, no significant difference was found. This research was conducted prior to the latest update to the proposed revision and diagnostic category concerning bereavement in the DSM‐5 of April 2012, but many observations and recommendations concerning PGD made by the therapists participating in this research can be seen to be applicable to PCB‐RD. Implications: The implications of this research for assessing and diagnosing grief, and ways of working with bereaved clients, are discussed.     

The transgender parent: Experiences and constructions of pregnancy and parenthood for transgender men in Australia

Background: Transgender (trans) men are commonly born with the reproductive anatomy that allows them to become pregnant and give birth and many wish to do so. However, little is known about Australian trans men's experiences of desiring parenthood and gestational pregnancy.

Aims: The present study aims to address this gap in the literature through addressing the following research questions: how do Australian trans men construct and experience their desire for parenthood? And, how do Australian trans men construct and experience gestational pregnancy?

Methods: This study aimed to explore these experiences, through a mixed-methods research design using online survey data and one-on-one interviews, with 25 trans men, aged 25–46 years old, who had experienced a gestational pregnancy. Data were analyzed using thematic analysis.

Results: For our participants, parenthood was initially described as alienating and complex, however transitioning enabled participants to negotiate and construct their own parenting identity. Pregnancy was positioned as a problematic but “functional sacrifice,” however formal assisted fertility experiences were rife with exclusion. At the same time dysphoria associated with withdrawing from testosterone and the growing fecund body were significantly troubling. Changes to the chest were of particular concern for participants. Exclusion, isolation, and loneliness were the predominant features of trans men's experiences of gestational pregnancies. Healthcare systems are not generally supportive of trans bodies and identities and trans men encounter significant issues when interacting with healthcare providers. As such, the results reinforce the importance of inclusive and specialized health services to support trans men through pregnancy.     

Differential developmental trajectories for egocentric, environmental and intrinsic frames of reference in spatial memory

We studied the development of spatial frames of reference in children aged 3-6 years, who retrieved hidden toys from an array of identical containers bordered by landmarks under four conditions. By moving the child and/or the array between presentation and test, we varied the consistency of the hidden toy with (i) the body, and (ii) the testing room. The toy's position always remained consistent with (iii) the array and bordering landmarks. We found separate, additive performance advantages for consistency with body and room. These effects were already present at 3 years. A striking finding was that the room effect, which implies allocentric representations of the room and/or egocentric representations updated by self-motion, was much stronger in the youngest children than the body effect, which implies purely egocentric representations. Children as young as 3 years therefore had, and greatly favoured, spatial representations that were not purely egocentric. Viewpoint-independent recall based only on the array and bordering landmarks emerged at 5 years. There was no evidence that this later-developing ability, which implies object-referenced (intrinsic) representations, depended on verbal encodings. These findings indicate that core components of adult spatial competence, including parallel egocentric and nonegocentric representations of space, are present as early as 3 years. These are supplemented by later-developing object-referenced representations.     

Alternative Factor Models and Heritability of the Short Leyton Obsessional Inventory—Children’s Version

An alternative models framework was used to test three confirmatory factor analytic models for the Short Leyton Obsessional Inventory-Children’s Version (Short LOI-CV) in a general population sample of 517 young adolescent twins (11–16 years). A one-factor model as implicit in current classification systems of Obsessive–Compulsive Disorder (OCD), a two-factor obsessions and compulsions model, and a multidimensional model corresponding to the three proposed subscales of the Short LOI-CV (labelled Obsessions/Incompleteness, Numbers/Luck and Cleanliness) were considered. The three-factor model was the only model to provide an adequate explanation of the data. Twin analyses suggested significant quantitative sex differences in heritability for both the Obsessions/Incompleteness and Numbers/Luck dimensions with these being significantly heritable in males only (heritability of 60% and 65% respectively). The correlation between the additive genetic effects for these two dimensions in males was 0.95 suggesting they largely share the same genetic risk factors.     

Young women’s construction of their post-cancer fertility

Younger women diagnosed with cancer often face compromised fertility as a result of their treatment. However, previous research has adopted a biomedical model of fertility and utilised hypothetico-deductive research methods which have not allowed for full exploration of women’s subjectivity. This study explored younger women’s construction of their fertility post-cancer, and their discussions of fertility with healthcare professionals, from a social constructionist epistemology. Semi-structured one-to-one interviews were conducted with eight women aged 18–26, across a variety of cancer types. Foucaultian Discourse Analysis identified three subject positions associated with fertility concerns: ‘Inadequate woman: Accepting the motherhood mandate’; ‘Adequate woman: Resisting the motherhood mandate’; and ‘Survival of the fittest: Woman as genetically defective’. Implications of these subject positions included feelings of inadequacy, fear and devastation; feeling undesirable to romantic partners; and concern about passing on cancer-positive genes. In describing healthcare professional interactions, women adopted positions of ‘Satisfied patient’; ‘Passive recipient patient’; or ‘Resisting the passive patient position’. Accounts of inadequate information provision were associated with anger and frustration, whereas feeling adequately informed was associated with satisfaction at making decisions about fertility preservation. These results suggest that fertility is of importance to young women cancer survivors, and that compromised fertility can negatively impact subjectivity.
