Hangover sensitivity after controlled alcohol administration as predictor of post-college drinking

Predicting continued problematic levels of drinking after the early 20's could help with early identification of persons at risk. This study investigated whether hangover insensitivity could predict postcollege drinking and problems beyond the variance due to drinking patterns. In a preliminary study, 134 college seniors from a laboratory study of hangover (Time 1) were contacted and assessed 1-4 years (M = 2.3) later (Time 2). Hangover severity was studied after controlled alcohol administration to a specific dose while controlling sleep and environmental influences. Hangover severity at Time 1 was used to predict Time 2 drinking volume and problems while controlling for relevant demographics and Time 1 drinking volume. Hangover insensitivity at Time 1 tended to predict a clinical level of alcohol problems with a large statistical effect size. Hangover sensitivity also correlated positively with sensitivity to alcohol intoxication. Hangover severity did not predict future drinking volume. Hangover insensitivity correlates with insensitivity to intoxication and might predict more serious alcohol problems in the future, suggesting that a future larger study is warranted. Hangover insensitivity could result from physiological factors underlying low sensitivity to alcohol or risk for alcoholism.     

Conducting behavioral research on Amazon’s Mechanical Turk

Amazon’s Mechanical Turk is an online labor market where requesters post jobs and workers choose which jobs to do for pay. The central purpose of this article is to demonstrate how to use this Web site for conducting behavioral research and to lower the barrier to entry for researchers who could benefit from this platform. We describe general techniques that apply to a variety of types of research and experiments across disciplines. We begin by discussing some of the advantages of doing experiments on Mechanical Turk, such as easy access to a large, stable, and diverse subject pool, the low cost of doing experiments, and faster iteration between developing theory and executing experiments. While other methods of conducting behavioral research may be comparable to or even better than Mechanical Turk on one or more of the axes outlined above, we will show that when taken as a whole Mechanical Turk can be a useful tool for many researchers. We will discuss how the behavior of workers compares with that of experts and laboratory subjects. Then we will illustrate the mechanics of putting a task on Mechanical Turk, including recruiting subjects, executing the task, and reviewing the work that was submitted. We also provide solutions to common problems that a researcher might face when executing their research on this platform, including techniques for conducting synchronous experiments, methods for ensuring high-quality work, how to keep data private, and how to maintain code security.     

Attention capture by novel stimuli

In several experiments, observers were given glimpses of 4-word arrays. Accuracy of word localization was tested after each array. Some words, called familiar, appeared many times across the series of arrays; others, called novel, appeared only once. The ratio of novel to familiar words in an array ranged from 0:4 to 4:0. When familiar and novel words were not intermixed (in 0:4 and 4:0 arrays), localization accuracy was higher for familiar words. However, when they were intermixed, especially in 1:3 arrays, accuracy tended to be higher for the novel words. This novel popout effect was the outcome of the suppressed localizability of the familiar words (relative to the 0:4 baseline) and the enhanced localizability of the novel words (relative to the 4:0 baseline). Novel popout may reflect an automatic orientation of attention away from more fluently unfolding regions of the perceptual field (familiar objects) and toward less fluently unfolding regions (novel objects).     

Motives, involvements, and leadership among black college students

Thematic Apperceptive measures of achievement, affiliation, and power motives, together with consensual judges’ ratings for several clusters of attitudes, beliefs, and actions, and objective data on office-holding were obtained from thirty-eight Black undergraduate university students Overall, need for Power was related to holding office, being rated as influential, and participating in the Black Repertory Theatre. Among Northern-reared Blacks, need for Power related to ratings of activity in the extramural Black community and distrust of the System, among Southern-reared Blacks, need for Power and need for Achievement related to ratings of Pragmatism.     

Heart rate deceleration after erroneous responses

Summary In an eight-choice reaction task, the influence of erroneous responses upon the temporary changes in the level of heart rate (HR) was studied. It was shown that after errors there was a short-term deceleration of the HR-level, while after correct responses an accelerating tendency was found. This phenomenon has to be regarded as an additional source of fluctuations of the HR-level. Therefore, it has to be taken into account when suppression of sinus arrhythmia is used for assessing the level of mental load.     

Decision-Making in Married and Unrelated Couples

The decision-making performance of 20 married and 20 synthetic couples, all college students, was compared using the Ferreira-Winter Questionnaire technique. Married couples showed (a) greater spontaneous agreement with each other prior to conjoint discussion, (b) less politeness, (c) more intrusive interruptions, and (d) a lesser exchange of explicit information between husband and wife. Although married couples arrived at more "democratic" or representative decisions in a faster time, this was due to their greater degree of prior shared values and interests. The effects of the history and context of the relationship between subjects upon their pattern of communication and possible contrasts between normal and abnormal couples are discussed.     

Toward a Definition of Family Resilience: Integrating Life-Span and Family Perspectives

Family resilience is a relatively new construct that describes how families adapt to stress and bounce back from adversity. Literature pertaining to resilience as a family-level variable is reviewed. An overview of the developmental psychopathology literature dealing with individual resilience is also presented. Implications for extending the study of family resilience drawn from research on individual resilience are discussed and a definition of family resilience is proposed.     

Commentary: Tending the Garden of Personality

ABSTRACT In this Commentary for the special issue of the Journal of Personality, we discuss the uses and limitations of taxonomies in personality, drawing on the role of taxonomic efforts in other sciences. We endorse Mc Adams's concept of several “levels” (perhaps three: traits, motives and cognitive structures, and core unity themas or identity) for ordering and arranging the major variables of personality. We argue that these levels should be considered independent and distinct: Each level has its own range of convenience, and no level can be reduced to any other level. We suggest that the concept of conflict—within and across levels—is a useful way to understand certain problematic cases. Finally, we argue that the social macrocontext (gender, class, race, culture, and history) has unfortunately been neglected in most personality theories and taxonomies of variables. We illustrate the importance of social macrocontext with a brief discussion of the case of Maya Angelou.
