EthoVision: A versatile video tracking system for automation of behavioral experiments

The need for automating behavioral observations and the evolution of systems developed for that purpose is outlined. Video tracking systems enable researchers to study behavior in a reliable and consistent way and over longer time periods than if they were using manual recording. To overcome limitations of currently available systems, we have designed EthoVision, an integrated system for automatic recording of activity, movement, and interactions of animals. The EthoVision software is presented, highlighting some key features that separate EthoVision from other systems: easy file management, independent variable definition, flexible arena and zone design, several methods of data acquisition allowing identification and tracking of multiple animals in multiple arenas, and tools for visualization of the tracks and calculation of a range of analysis parameters. A review of studies using EthoVision is presented, demonstrating the system’s use in a wide variety of applications. Possible future directions for development are discussed.     

The Understanding and Treatment of Immigrant Trauma Survivors: Finding the Right Mix

This paper reviews attempts by three authors to describe psychoanalytic conceptualizations and treatment of torture victims. It argues that because the transference-countertransference configuration with immigrants who have not suffered torture is very similar to that of torture survivors, that no special diagnostic categories, theories, or treatment methods are needed to work with torture survivors. Second, the paper contends that newer psychoanalytic paradigms such as Hoffman's Social Constructivism may assist clinicians to capture the richness and complexity of clinical work with torture survivors better than do traditional analytic conceptions such as neutrality. Via an analysis of the three papers in this volume, I conclude with a consideration of the strengths and the weaknesses of the field of cross-cultural psychotherapy in general.     

Attentional templates regulate competitive interactions among attended visual objects

In two experiments, we examined the mechanisms responsible for creating a zone of interference surrounding an attended visual object (see, e.g., Mounts & Gavett, 2004). In Experiment 1, the similarity between attended stimuli and noise items was manipulated in order to contrast an account based on competitive interactions between attended items with an account based on inefficient filtering of unattended stimuli. Consistent with the competitive interaction account, the data revealed that similarity between attended items increased the strength of localized interference, whereas similarity of noise items to the attended stimuli did not. Experiment 2 showed that the interference observed between attended items was determined by their match to attentional templates.     

Privileged access,externalism, and ways of believing

By exploiting a concept called ways of believing, I offer a plausible reformulation of the doctrine of privileged access. This reformulation will provide us with a defense of compatibilism, the view that content externalism and privileged access are compatible.     

Comment on Bridges and Kunselman (2005)

A case is made that a clear understanding of premature mortality of Status Indians due to suicide, homicide, and motor vehicle accidents must begin with a clear idea of what the indicator, potential years of life lost before age 75 (PYLL), is, and how it was measured or calculated.     

Effects of retrieval practice on consumer memory for brand attributes

The effect of retrieval practice on memory for brand attributes was examined. Participants were presented with advertisements for fictional products so each contained a number of brand attributes relating to the nature of the product and its qualities. Following this, participants practiced recalling a subset of those attributes either 3 or 6 times. The act of retrieving some brand information inhibited the recall of other brand information that was not practiced, but only when repeated retrieval practice took place 6 times. This is the first demonstration of inhibitory effects in consumers' memory using the retrieval practice paradigm.     

Borderline personality as a self-other representational disturbance

A great deal has been written about the nature of borderline personality. We maintain that borderline psychopathology emanates from particular disturbances in mental representations-impairment in the ability to maintain and use benign and integrated internal images of self and others-and that these troubled ways of thinking drive the troubled interpersonal relations, affective instability, and impulsivity associated with borderline. Aspects of borderline self-other representational disturbances are present across a wide theoretical spectrum, and a number of research methodologies already exist to assess the phenomena. We conclude that borderline attributes exist on continua, and summarize important features as: (1) unstable mental images of self and others, often marked by self-loathing and attributions of malevolence to others; (2) interactions with others organized around a fundamental need for care that is felt to be necessary for basic functioning; (3) fear of others based on expectations of being mistreated and disappointed and/or terror of having one's identity subsumed by another person; (4) difficulty considering multiple and/or conflicting perspectives, with a tendency toward concrete, all-or-none, or black-and-white, thinking and distortion of reality; and (5) sadomasochistic interpersonal interactions in which a person alternatively inflicts suffering on others and suffers at the hands of others.     

Why older adults make more immediate treatment decisions about cancer than younger adults

Literature relevant to medical decision making was reviewed, and a model was outlined for testing. Two studies examined whether older adults make more immediate decisions than younger adults about treatments for prostate or breast cancer in authentic scenarios. Findings clearly showed that older adults were more likely to make immediate decisions than younger adults. The research is important because it not only demonstrates the consistency of this age-related effect across disease domains, gender, ethnic groups, and prevalent education levels but begins to investigate a model to explain the effect. Major reasons for the effect focus on treatment knowledge, interest and engagement, and cognitive resources. Treatment knowledge, general cancer knowledge, interest, and cognitive resources relate to different ways of processing treatment information and preferences for immediate versus delayed decision making. Adults with high knowledge of treatments on a reliable test tended to make immediate treatment decisions, which supports the knowledge explanation. Adults with more cognitive resources and more interest tended to delay their treatment decisions. Little support was found for a cohort explanation for the relationship between age and preference for immediate medical decision making.
