Images of the Abyss

Images of the abyss in traditional Christian theology and psychology are generally symbolic of hell, destruction, or death. Here, the notion of abyss is regarded afresh through the experiences of Jacob Boehme, the 17^th century German shoemaker and mystic, and Carl Jung, the 20^th century Swiss psychoanalyst. Boehme's pre-existent abyss, which he called the Ungrund, or un-ground, and saw as underlying all of creation, even God, relates to the unitary reality of Jung's Self. The Self is before the beginning of the individual human psyche and also its ultimate goal in terms of psychological life.     

A novel continuous inhibitory-control task: variation in individual performance by young pheasants (<Emphasis Type="Italic">Phasianus colchicus</Emphasis>)

Inhibitory control enables subjects to quickly react to unexpectedly changing external demands. We assessed the ability of young (8 weeks old) pheasants Phasianus colchicus to exert inhibitory control in a novel response-inhibition task that required subjects to adjust their movement in space in pursuit of a reward across changing target locations. The difference in latencies between trials in which the target location did and did not change, the distance travelled towards the initially indicated location after a change occurred, and the change-signal reaction time provided a consistent measure that could be indicative of a pheasant’s inhibitory control. Between individuals, there was a great variability in these measures; these differences were not correlated with motivation either to access the reward or participate in the test. However, individuals that were slower to reach rewards in trials when the target did not change exhibited evidence of stronger inhibitory control, as did males and small individuals. This novel test paradigm offers a potential assay of inhibitory control that utilises a natural feature of an animal’s behavioural repertoire, likely common to a wide range of species, specifically their ability to rapidly alter their trajectory when reward locations switch.     

Scientist-practitioner family therapists, postmodern medical practitioners and expert parents: second-order change in the Eating Disorders Program at The Children's Hospital at Westmead

The Maudsley model of family-based treatment for anorexia integrates a variety of schools of family therapy, and has been developed and supported by a number of randomized controlled trials. In this paper we will describe the systemic organizational changes that have occurred as a result of the inclusion of this model in the Eating Disorders Program at The Children's Hospital at Westmead over an eighteen-month period, including a process of mutual influence between medical practitioners and family therapists. These changes have contributed towards a dramatic improvement in clinical outcomes including a significant drop in readmission rates to hospital.

A forgotten resource critical to the future of behavior analysis: undergraduate psychology majors

The demand for board-certified applied behavior analysts is not being met, and there is a perception that fewer students are exposed to systematic courses in basic and applied behavior analysis than was true a generation ago. This article outlines how we have successfully implemented an undergraduate curriculum in behavior analysis within a traditional department of psychology. Certification credentials offered by the Behavior Analysis Certification Board facilitated the approval of this curriculum, and the cultural practice selection contingencies that supported the creation of our curriculum in behavior analysis may be similar at other comprehensive universities. Advice for developing an undergraduate program in behavior analysis within a psychology department is outlined. We also summarize strategies we have used to attract talented students to the courses and the significant impact these strategies have had on the number of our graduates who pursue graduate training in basic and applied behavior analysis. Attracting the best and brightest students to behavior analysis is critical to the future of the field.     

Age-related preservation of top-down attentional guidance during visual search

Younger (19-27 years of age) and older (60-82 years of age) adults performed a letter search task in which a color singleton was either noninformative (baseline condition) or highly informative (guided condition) regarding target location. In the guided condition, both age groups exhibited a substantial decrease in response time (RT) to singleton targets, relative to the baseline condition, as well as an increase in RT to nonsingleton targets. The authors conclude that under conditions that equate the physical structure of individual displays, top-down attentional guidance can be at least as effective for older adults as for younger adults.     

Intersection as key locations for bearded capuchin monkeys (<Emphasis Type="Italic">Sapajus libidinosus</Emphasis>) traveling within a route network

There is evidence that wild animals are able to recall key locations and associate them with navigational routes. Studies in primate navigation suggest most species navigate through the route network system, using intersections among routes as locations of decision-making. Recent approaches presume that points of directional change may be key locations where animals decide where to go next. Over four consecutive years, we observed how a wild group of bearded capuchin monkeys used a route network system and Change Point locations (CPs) in the Brazilian ecotone of Cerrado–Caatinga. We built 200 daily routes of one wild bearded capuchin group. We used ArcGIS, the Change Point Test, Spatial Analysis in Macroecology (SAM), and statistical models to test the hypothesis that wild bearded capuchins use CPs located along routes in a different fashion than they use the CPs located at intersections of routes. A logistic regression model was used to determine the landscape variables affecting capuchins’ directional changes at intersections or along routes. CPs at intersections were important points of travel path changes, whereas CPs along routes represented a zig-zag movement along the routes following the landscape features. CPs at intersections were associated with steeper terrains and shorter distances from important resources, along with better visibility of the home range. Our results support the hypothesis that intersections among routes in the route network system are located at points where monkeys have the best visibility available to make decisions on where to visit next.     

The inhibitory control of pheasants (Phasianus colchicus) weakens when previously learned environmental information becomes unpredictable

Animal Cognition - Inhibitory control (IC) is the ability to intentionally restrain initial, ineffective responses to a stimulus and instead exhibit an alternative behaviour that is not pre-potent...
