Visibility distances with halogen and conventional headlights

Abstract.— Using visibility distance as a criterion, halogen and conventional continental European high and low-beam headlights were compared in a series of field experiments. On high-beam without opposing light the halogen headlights offered about 25% longer visibility distances than the conventional headlights. With both opposing cars using low-beam there was a slight advantage (<5 m) in favour of halogen headlights. The optimal dipping distance was a function of high-beam system (intensity) rather than low-beam system. Small differences in aiming, atmosphere etc. caused larger differences in visibility distance than did the headlight system.     

The role of selective attention in perceptual and affective priming

Two kinds of perceptual priming (word identification and word fragment completion), as well as preference priming (that may rely on special affective mechanisms) were examined after participants either read or named the colors of words and nonwords at study. Participants named the colors of words more slowly than the colors of nonwords, indicating that lexical processing of the words occurred at study. Nonetheless, priming on all three tests was lower after color naming than after reading, despite evidence of lexical processing during color naming shown by slower responses to words than to nonwords. These results indicate that selective attention to (rather than the mere processing of) letter string identity at study is important for subsequent repetition priming.

Reassessing the Role of Anxiety in Vote Choice

Much recent political psychology scholarship has examined the role of anxiety in vote choice. This work generally argues that anxiety affects vote choice indirectly by causing citizens to more thoroughly search for and process political information. This indirect effect of anxiety leads citizens to rely less on heuristics, such as party, and more on substantive information, such as policy positions. The most prominent example of this scholarship is the Affective Intelligence (AI) theory of emotions. In this paper, we use cross-sectional and panel survey data to test AI against two simpler alternatives: (1) that emotions directly influence candidate evaluations and (2) that candidate evaluations directly influence emotions. We first show that these simpler alternatives can produce the complex, cross-sectional interactions that provide the principal support for AI. Then, using panel data to better assess causal direction, we find little support for AI, some evidence that emotions directly influence candidate evaluations, and strong evidence that candidate evaluations directly influence emotions. Scholars, we conclude, should be hesitant to abandon these simpler explanations in favor of AI.     

A consequence of school grade labels: preservice teachers’ interpretations and recall of children’s classroom behavior

This study investigated whether preservice teachers’ attitudes surrounding school grade labels influenced interpretations and recall of children’s classroom behavior using the automatic attitude activation model (Fazio, In R. M. Sorrentino & E. T. Higgins (Eds.), Handbook of motivation and cognition: Foundations of social behavior, 1986) as a theoretical framework. Participants were randomly assigned to one of three conditions: The expectation of viewing a video of children in schools labeled as “A,” “F,” or “typical” as a result of the school’s aggregated student performance on standardized tests. Results indicated that participants who believed that they were viewing a video of an “F” classroom recalled more negative and fewer positive behaviors compared to the “typical” classroom. Likewise, there was a trend for participants to recall more negative and fewer positive behaviors when viewing a video of an “F” compared to an “A” school. Therefore, negative attitudes about a school label of “F” biased preservice teachers’ perceptions and memories of children’s classroom behaviors.

Ecological Aspects of Group Behavior in Social Isolation1

The present study examined how socially isolated groups were affected by and used their physical environment during an 8-day period. Pairs of men were isolated under different conditions of privacy, outside stimulation, and expected time in isolation. Measures were taken of environmentally oriented behaviors such as social activities; territoriality for beds, chairs, and areas of the room, use of beds; and performance on team and individual tasks. The results indicate that unsuccessful groups exhibited a pattern of behavior reflecting their misestimate of the demands of the situation. The fact that many different levels of behavior fit together, over time, suggested the importance of an ecological approach to interpersonal behavior which examines many levels of functioning over time as a system, with particular emphasis on the mutual relationship between man and his environment.     

Psychodynamic assessment of changes in children with autism under psychoanalytic treatment

In this article the authors report insights into autism developed through their extensive experience of psychoanalytic therapy with children with autism. The fi rst stages of body psychic development are seriously disrupted by this pathology, resulting in primitive anxieties of falling and of being liquefi ed. These anxieties are connected to the fragile development of body ego and of its related spatiotemporal organisation. The changes in children observed by the authors during the therapeutic process lead them to offer a psychodynamic assessment tool, which revolves principally around the development of body ego. After the initial state of 'severe autism', the authors describe three stages: the stage of 'recovery of the skin' (Bick); the established 'symbiotic phase', subdivided into 'vertical then horizontal splitting of the body ego'; and fi nally the stage of 'individuation'. First, the authors describe the principal psychoanalytic approaches to autism and refl ect on the links possible with nonpsychoanalytic work.     

Inward, Outward, and Upward: Cognitive Aspects of Prayer

Recent investigations concerning ways people employ prayer typically suffer from either a fundamentally atheoretical approach or an indiscriminant mixing of affective, behavioral, and cognitive components. The present study examines the theory that a general concept of prayer–as–connection contains prayers of inward (connection with oneself), outward (human–human connection), or upward (human–divine connection) foci. Participants rated words or phrases according to what they "thought about" while praying. Factor analysis revealed eight primary factors: two inward, four outward, and two upward. Three second–order factors emerged (two outward and one upward). However, no general factor appeared.
