Substance P facilitation of memory: effects in an appetitively motivated learning task

Food deprived, heterogeneous strain (HS/IBG) mice were trained on two different discrimination tasks for food reinforcement. In one experiment animals were trained to make spatial discriminations in a T maze. Immediately after training they were given subcutaneous injections of either substance P (1 ng/g) or vehicle. Twenty-four hours later the animals were given reversal training in the same maze. The results showed that substance P-treated animals took significantly longer to acquire the reversal habit than did control mice. In a second experiment, animals were trained to make visual discriminations in a T maze. Immediately after reaching acquisition criterion animals were injected with either substance P (1 ng/g) or vehicle. Different groups of mice were retrained on the same task either 1, 2, 3, or 7 days after original learning. Savings scores were calculated and, at every interval, substance P-treated mice retained the task better than control animals. One interpretation of these data is that substance P-treated mice remembered the original task significantly better than vehicle-injected control animals.     

Can job seekers achieve more through networking? The role of networking intensity,self-efficacy,and proximal benefits

The authors develop and evaluate an online networking intervention, Building Relationships and Improving Opportunities (BRIO), built in conjunction with the networking literature and social cognitive theory (Bandura, 1986, 1999). A field experiment using 491 unemployed job seekers shows that the intervention increases networking intensity, networking self-efficacy, and proximal networking benefits. Further, the intervention generates higher quality reemployment through its positive effects on networking self-efficacy. Individuals who completed the intervention and were also lower in extraversion showed the most positive improvements in networking self-efficacy and reemployment quality. The study advances the literature by uncovering the mechanisms through which a networking intervention may result in improved reemployment success, and demonstrating the moderating role of individual differences in affecting intervention outcomes. The study helps practice by providing a publicly available, research-based training to improve job search networking.
