The Impact of Blocked vs. Distributed Category Learning on Subsequent Generalization

Description
It is a well-established finding in memory research that spacing or distributing information, as opposed to blocking all the information together, results in an enhanced memory of the learned material.

It is a well-established finding in memory research that spacing or distributing information, as opposed to blocking all the information together, results in an enhanced memory of the learned material. Recently, researchers have decided to investigate if this spacing effect is also beneficial in category learning. In a set of experiments, Carvalho & Goldstone (2013), demonstrated that a blocked presentation showed an advantage during learning, but that ultimately, the distributed presentation yielded better performance during a post-learning transfer test. However, we have identified a major methodological issue in this study that we believe contaminates the results in a way that leads to an inflation and misrepresentation of learning levels. The present study aimed to correct this issue and re-examine whether a blocked or distributed presentation enhances the learning and subsequent generalization of categories. We also introduced two shaping variables, category size and distortion level at transfer, in addition to the mode of presentation (blocked versus distributed). Results showed no significant differences of mode of presentation at either the learning or transfer phases, thus supporting our concern about the previous study. Additional findings showed benefits in learning categories with a greater category size, as well as higher classification accuracy of novel stimuli at lower-distortion levels.

Humor Based Coping: For Which Negative Emotions Do We Use Humor?

Description

People use a variety of emotion regulation strategies to cope with difficult situations. Although there is research supporting humor as an effective emotion regulation strategy, less is known about what circumstances lead people to use humor and what negative emotions humor seems to be the most helpful in mitigating.

People use a variety of emotion regulation strategies to cope with difficult situations. Although there is research supporting humor as an effective emotion regulation strategy, less is known about what circumstances lead people to use humor and what negative emotions humor seems to be the most helpful in mitigating. The current study aimed to determine to what extent specific negative emotions lead people to choose humor as an emotion regulation strategy. Participants wrote about a neutral situation and then selected from four card decks with different stimuli (funny, pleasant, awe-inspiring, or neutral). Participants were then randomly assigned to a negative emotion condition (sadness, embarrassment, anxiety, or anger) and wrote about a situation in which they have experienced that specific emotion. They then completed the card selection task again. We compared the number of funny cards chosen between the neutral vs negative emotion trials for each emotion. We found that card selection did not change significantly from the neutral-affect trial to the negative emotion trial across any of the negative emotions. Limitations and future directions are discussed.
