The potentiation effect during serial conditioning

The development of suppression in rats to a target conditioned stimulus (CS) was compared in trace and serial conditioning procedures. The interval between the end of the target CS and the shock unconditioned stimulus (US) was filled by a second CS in the serial, but not the trace, procedure. In five experiments the serial procedure produced superior conditioning. This potentiation effect, however, depended critically upon the level of conditioning to the stimulus interpolated between the target CS and the US. When conditioning to the interpolated CS was either reduced by giving independent nonreinforced trials with this CS alone or enhanced by independent reinforced trials, the potentiation effect was abolished. In addition, the insertion of a trace interval between the target and interpolated CSs reduced the effect. However, the magnitude of conditioning to the target CS was unaffected by post-conditioning changes in the conditioned strength of the interpolated CS. These findings are discussed in terms of the contribution of both the association between the CSs themselves, which is inherent in the serial procedure, and that between the target CS and the US.     

Unique associations between anxiety,depression and motives for approach and avoidance goal pursuit

This study investigated the shared and distinct associations between depressive and anxious symptoms and motives for pursuing personal goals. One hundred and thirty-six undergraduates generated approach and avoidance goals and rated each on intrinsic, identified, introjected and external motives. Anxious and depressive symptoms showed significant unique associations with distinct motives. Specifically, depressive symptoms predicted significant unique variance in intrinsic motivation for approach goals (but not avoidance goals), whereas anxious symptoms predicted significant unique variance in introjected regulation for approach and avoidance goals. Some of these findings were moderated by gender. The findings broadly support the notion that depression is uniquely characterised by reduced enjoyment of approach goal pursuit whereas anxiety is uniquely characterised by pursuit of goals in order to avoid negative outcomes. We suggest that these findings are compatible with regulatory focus theory and suggest that motives for goal pursuit are important in understanding the relation between goals and specific mood disorder symptoms.     

Black male client, white female counsellor: Making positive use of transference phenomena

The content and process of transference issues over a 9-month period of counselling contact between a white, female counsellor and a black, male client are examined. An attempt is made to show the positive effects that may come about through a non-ethnic- and non-gender-matched counsellor-client dyad, and to explore the benefits to the client of counsellor similarity and difference.     

Understanding Families of Adults With Cancer: Combining the Clinical Course of Cancer and Stages of Family Development

Since the 1970s, counseling professionals have recommended that cancer be regarded as an illness that affects the entire family. This article combines research on understanding the impact of cancer on the family that relates both to the clinical course of cancer and to the developmental stages of the family system. The combination of these 2 dimensions provides counselors with a template for (a) understanding the current literature regarding cancer's impact on the family, (b) helping counselors formulate intervention strategies for the families of cancer patients, and (c) recognizing future directions for research regarding the needs of family members of cancer patients.     

The Organization of Extrinsic Neurons and Their Implications in the Functional Roles of the Mushroom Bodies in Drosophila melanogaster Meigen

Although the importance of the Drosophila mushroom body in olfactory learning and memory has been stressed, virtually nothing is known about the brain regions to which it is connected. Using Golgi and GAL4–UAS techniques, we performed the first systematic attempt to reveal the anatomy of its extrinsic neurons. A novel presynaptic reporter construct, UAS-neuronal synaptobrevin–green fluorescent protein (n-syb–GFP), was used to reveal the direction of information in the GAL4-labeled neurons. Our results showed that the main target of the output neurons from the mushroom body lobes is the anterior part of the inferior medial, superior medial, and superior lateral protocerebrum. The lobes also receive afferents from these neuropils. The lack of major output projections directly to the deutocerebrum’s premotor pathways discourages the view that the role of the mushroom body may be that of an immediate modifier of behavior. Our data, as well as a critical evaluation of the literature, suggest that the mushroom body may not by itself be a “center” for learning and memory, but that it can equally be considered as a preprocessor of olfactory signals en route to “higher” protocerebral regions.     

A comparison of female supervisors in business and government organizations

This exploratory study compared the life style and interpersonal need orientation, leadership style, and perception of the organization structure of female supervisors in business and government organizations. The government group had a significantly higher formalistic and lower sociocentric and personalistic life style orientation; lower needs for expressed control, expressed affection, wanted inclusion, wanted affection, and a higher need for wanted control; were lower on consideration and higher on structure leadership dimensions; and perceived their organization as being more bureaucratic and less collaborative and coordinative than the business group. The findings were discussed in terms of the processes of individual-organization congruity and organizational socialization.     

Time error in lifted weights as affected by presentation order and judgment mode

In the method of constant stimulus differences, results obtained under two presentation orders (standard first and standard second) are commonly combined to eliminate time error. The present study shows that this technique is not adequate for controlling time error as the presentation orders have differential effects upon PSE. Using a two-handed technique, 96 subjects judged lifted weights on the comparative rating scale. The subjects lifted the standard before, with, or after the variable stimulus. They also either judged the standard in terms of the variable or the variable in terms of the standard (mode of judgment). Judgment mode, a previously uninvestigated confounding variable of presentation order was not an important factor in influencing the value of the PSE.
