Quantity discrimination in a spontaneous task in a poison frog

Animal Cognition - The use of quantitative information underlies a range of animal behaviors. There are thought to be two parallel systems for judging quantity: a precise representation of small...     

Sales Force Compensation Plans Incorporating Multidimensional Sales Effort and Salesperson Efficiency

Sales force compensation models are often constrained by the assumption that salesperson effort is unidimensional. Some models have extended this scenario to multiple products but retain the “single-effort” assumption. In addition, salesperson efficiency has been ignored. As selling is clearly multidimensional, we present a formulation of an agency model (MIPAM) that incorporates multidimensional sales effort as well as salesperson efficiency. Using the model, we also show that under certain assumptions, we can build the second-order condition of the agent’s maximization into the principalagent problem, instead of assuming it, as has been done in the past.     

Orientalism in Euro-American and Indian psychology: historical representations of "natives" in Colonial and postcolonial contexts

The author examines the historical role of Euro-American psychology in constructing Orientalist representations of the natives who were colonized by the European colonial powers. In particular, the author demonstrates how the power to represent the non-Western "Other" has always resided, and still continues to reside, primarily with psychologists working in Europe and America. It is argued that the theoretical frameworks that are used to represent non-Westerners in contemporary times continue to emerge from Euro-American psychology. Finally, the author discusses how non-Western psychologists internalized these Orientalist images and how such a move has led to a virtual abandonment of pursuing "native" forms of indigenous psychologies in Third World psychology departments.     

An investigation of self-ambivalence in obsessive-compulsive disorder

Individuals vulnerable to obsessive-compulsive disorder (OCD) are hypothesized to have ambivalence about their self-worth, morality and lovability [Guidano, V., & Liotti, G. (1983). Cognitive processes and emotional disorders. New York: Guildford Press]. The purpose of this study was to examine whether self-ambivalence was associated with OCD phenomena and beliefs relevant to OCD. It also examined whether patients with OCD had higher levels of self-ambivalence compared to non-clinical controls and patients with other anxiety disorders. Participants were 73 OCD patients, 50 patients with another anxiety disorder, 225 non-clinical undergraduate students and 43 non-clinical community controls. They completed measures of self-ambivalence, OCD phenomena, OCD-relevant beliefs, depression, anxiety and self-esteem. Self-ambivalence was significantly associated with OCD phenomena and OCD-relevant beliefs, after controlling for self-esteem, depression and anxiety. Further, OCD participants were significantly more ambivalent than the non-clinical groups, but did not differ from anxious controls. It was argued that these results provide a basis for extending the cognitive-behavioural model of OCD to include ambivalent self-perceptions as a component of the cognitive mechanisms relevant to the disorder.     

Dysfunctional beliefs and psychopathology in Borderline Personality Disorder

This study examined the factor structure of the Borderline Personality Disorder subscale of the Personality Beliefs Questionnaire (PBQ-BPD; Butler, Brown, Beck, & Grisham, 2002), and the relationships between the emergent factors and psychopathology. The sample comprised 184 patients diagnosed with borderline personality disorder (BPD). Exploratory factor analysis yielded three factors relating respectively to dependency, distrust, and the belief that one should act preemptively to avoid threat. Although the three factors were significantly associated with depression, only dependency and distrust significantly correlated with hopelessness. Distrust was the sole factor that correlated significantly with suicide ideation. These findings support the dimensional structure of the PBQ-BPD. Given its multidimensional structure, the scale can be used as a measure of belief profiles associated with BPD and as an aid to conceptualizing beliefs underlying a range of psychopathology associated with patients with BPD.     

The Impact of Angelina Jolie (AJ)’s Story on Genetic Referral and Testing at an Academic Cancer Centre in Canada

In May 2013, Angelina Jolie revealed to the media that she had undergone preventive double mastectomy after testing positive for a BRCA1 gene mutation. Media coverage has been extensive, but it is not clear how such a personal story affected the public and cancer genetics clinics. We conducted a retrospective review using data from the clinical database of the Familial Cancer Program at our centre. The impact of Ms. Jolie’s story on genetic counseling referrals and the appropriateness of such referrals were assessed and reported. The number of women referred for genetic counseling increased by 90 % after 6 months and remained high one year after AJ’s story with an increase of 88 % from baseline. The number of women who qualified for genetic testing increased by 105 % after 6 months; this increase persisted but was somewhat lower after one year with an increase of 68 % from baseline. Furthermore the number of BRCA1/2 carriers identified increased by 110 % after 6 months and by 42 % after one year.The effect of Mrs. Jolie’s story persisted one year after its release; however in the latter half of the year, the hereditary cancer risk of referred women was significantly lower than initially observed. The next challenge for our health care system will not only be to meet the increased demand for cancer genetic services in our region, but also to ensure that referrals and hence use of genetic counseling resources are appropriate.     

Counselling Older Adults Living in Residential Aged Care Settings: Four Illustrative Case Studies

The role of psychologists and other mental health professionals in long‐term care settings is undefined in Australia. Graduate psychology students receive little training in clinical geropsychology, and residential aged care providers do not routinely employ psychologists within such settings. Further, despite high rates of depression, neurocognitive problems, and other mental health problems, residents are rarely referred for evidence‐based psychological treatment. This article presents four case studies showing how psychology services may be employed in such settings within the context of a postgraduate psychology placement programme. These case studies emphasise the importance of engagement, the use of flexible and individualised treatment approaches, and the involvement of family and professional carers in the provision of psychological services. Psychology services in residential settings can have a positive impact on the care of older adults and their families.
