Can sleep habits predict driver behaviour?

IntroductionThe role of sleep hygiene (those factors that promote or disrupt effective sleep) on human performance was examined.ObjectiveThe study investigated the relationship between sleep hygiene and crash involvement.MethodMeasures of sleep hygiene and crash involvement were considered for a sample of over 6000 drivers.ResultsIt was found that poorer sleep hygiene was associated with younger age and greater crash involvement. The association between sleep hygiene and crash involvement remained when age and risk taking had been taken into account.ConclusionPoor sleep hygiene is associated with poorer performance as measured by crash involvement.     

Measuring context–response associations that drive habits

People achieve important life outcomes of health, financial security, and productivity by repeating operant behavior. To identify whether such operants reflect goal pursuit or habit, the present research introduces a new paradigm that yields objective measures of learning and controls for the motivations of goal pursuit. In two experiments, participants practiced a sequential task of making sushi and then completed a test of the strength of cue–response (habit) associations in memory. Finally, they repeated the sushi task without instructions while under cognitive load (designed to impede deliberation about goals). As predicted, greater task practice yielded stronger cue–response associations, which in turn promoted task success. Practice did not improve performance by enhancing goal intentions or other task motivations. We conclude that repetition facilitates performance by creating mental associations that automatically activate practiced, habitual responses upon perception of recurring context cues.     

The pull of the past: when do habits persist despite conflict with motives?

To identify the factors that disrupt and maintain habit performance, two field experiments tested the conditions under which people eat out of habit, leading them to resist motivational influences. Habitual popcorn eaters at a cinema were minimally influenced by their hunger or how much they liked the food, and they ate equal amounts of stale and fresh popcorn. Yet, mechanisms of automaticity influenced habit performance: Participants ate out of habit, regardless of freshness, only when currently in the context associated with past performance (i.e., a cinema; Study 1) and only when eating in a way that allowed them to automatically execute the response cued by that context (i.e., eating with their dominant hand; Study 2). Across all conditions, participants with weaker cinema-popcorn-eating habits ate because of motivations such as liking for the popcorn. The findings reveal how habits resist conflicting motives and provide insight into promising mechanisms of habit change.     

Catholicism,Protestantism, and Mexicanness on the US–Mexico border: discourses,narrative identities,habits, and affect

ABSTRACT

In Mexico, Catholicism and national identity are deeply intertwined through what we call a process of articulation. Thus, not surprisingly, despite the recent impressive growth of Protestantism in the nation, most people still believe that being Mexican and being Catholic are almost synonymous. Additionally, because the two identifications do not ‘cross each other’ (as the metaphor of intersectionality posits) but, instead, enter a very complex process of articulation in which each modifies the other, there is a particular way in which many Mexicans experience and perform their Catholicism, in the same vein that there is a particular way in which Catholics experience and perform their Mexicanness. Simultaneously, because neither nationality nor religion is narrated and/or performed in isolation to other forms of identification (e.g. race, ethnicity, region, gender) other possible identifications are also articulated or co-inform (in different ways) nationality and religion in the identitarian encounters that occur on the border. In the way people build their identifications around religion, narratives, practices, habits, affect, and emotions are continuously interrelated. We show that having an altar outside one’s house or making the sign of the cross on one’s body is both (depending on the unfolding of the social interactions and their patterns of relations) a non-linguistic discourse and a habit. We also show that their mere presence (in the case of altars) or performance (in the case of the sign of the cross) affect the people around the site or the performance, triggering complex emotions. That altar and sign of the cross can potentially be all these things simultaneously highlights their importance as ‘affective conductors’—stressing their significance as central objects in the intensification of relations that give new capacities to the entities involved in the patterns of relationship at play in the identitarian encounter at stake.     

Ratings in Black and White: does racial symmetry or asymmetry influence teacher assessment of a pupil’s work habits?

Racial asymmetry, the circumstance of having a teacher’s race differ from that of his or her student’s race, is often considered important because most Black students are taught by White teachers. This paper analyzes data from a nationally representative sample of students and teachers to ascertain the extent to which Black and White teachers differ in their evaluations of the work habits of their Black pupils. Unlike most other investigations on this topic, we explored the likelihood that subject matter and school demographics influence teacher-student relationships beyond the more visible factors of racial symmetry or asymmetry. Our analyses of NELS: 88 data using this framework reveal an inconsistent racial effect on teachers’ evaluations of Black students. The ratings of African American pupils by both Black and White teachers seem to be influenced by both the academic subject they teach and the demographic characteristic of the school. We discuss these findings and suggest avenues for further study.
