Assessing the sustainability of goal-based changes in adjustment over a four-year period

No published data addresses the longer-term sustainability of increases in well-being and adjustment derived from successful goal-striving. Although some theories and data suggest that such gains cannot be maintained, the sustainable happiness model [Lyubomirsky, S., Sheldon, K. M., & Schkade, D. (2005). Pursuing happiness: The architecture of sustainable change. Review of General Psychology, 9, 111–131.] suggests that successful intentional activity can indeed bring about lasting gains. In the current study, the “freshman goals” sample studied by Sheldon and Houser-Marko (Study 1) [Sheldon, K. M., & Houser-Marko, L. (2001). Self-concordance, goal-attainment, and the pursuit of happiness: Can there be an upward spiral? Journal of Personality and Social Psychology, 80, 152–165.] was revisited at the end of their senior year. Students who strove successfully during their freshman year, thereby enhancing their adjustment during that year, had maintained those gains three years later. Path modeling suggested that initial adjustment predicted subsequent goal-attainment which in turn predicted enhanced adjustment, combining recent theories concerning both the functional benefits of positive affect and the causes of sustainable gains in well-being.

Family psychological factors in relation to children's asthma status and behavioral adjustment at age 4

The objectives of this study were to determine whether family psychosocial factors influenced asthma development by age 4, and whether family factors and early wheezing illness were associated with behavioral adjustment at age 4. Participants were 98 children enrolled in an intervention study at 9-24 months and followed to age 4. Baseline evaluations assessed infants' respiratory illness severity, family psychosocial characteristics, and parental risk factors for asthma development. Active asthma categorization at age 4 utilized both parent report and objective data. Parents completed the Child Behavior Checklist (CBCL). Caregiver single-parent status, a composite of baseline family stresses, and early wheezing illness severity were associated with active asthma at age 4. The contribution of prenatal smoke exposure and early hospitalization to active asthma varied with racial/ethnic group membership. Maternal mental health and family stresses predicted CBCL scores at age 4, whereas early illness severity and hospitalization were unrelated to CBCL scores. CBCL scores were not elevated for children with active asthma at age 4. Family factors consistent with a negative emotional environment were associated with both active asthma and adjustment problems at age 4, suggesting that both outcomes may be influenced by a common factor.     

Posttraumatic Stress Disorder and Marital Adjustment: The Mediating Role of Forgiveness

The study assessed the effects of war captivity on posttraumatic stress symptoms and marital adjustment among Prisoners of War (POWs) from the Yom Kippur War. It was hypothesized that men's perception of level of forgiveness mediates the relation between posttraumatic symptoms and marital adjustment. The sample consisted of 157 Israeli veterans divided into 3 groups: 21 POWs with Posttraumatic Stress Disorder (PTSD), 58 former POWs without PTSD, and 70 control veterans. The findings indicated that former POWs with PTSD reported lower levels of marital satisfaction and forgiveness than veterans in the other 2 groups. In addition, men's perception of level of forgiveness mediated the relationship between their posttraumatic symptoms and their marital adjustment. The theoretical and clinical implications of these results are discussed.

Can fast and slow intelligence be differentiated?

Responses to items from an intelligence test may be fast or slow. The research issue dealt with in this paper is whether the intelligence involved in fast correct responses differs in nature from the intelligence involved in slow correct responses. There are two questions related to this issue: 1. Are the processes involved different? 2. Are the abilities involved different? An answer to these questions is provided making use of data from a Raven-like matrices test and a verbal analogies test, and the use of a psychometric branching model. The branching model is based on three latent traits: speed, fast accuracy and slow accuracy, and item parameters corresponding to each of these. The pattern of item difficulties is used to draw conclusions on the cognitive processes involved. The results are as follows: 1. The processes involved in fast and slow responses can be differentiated, as can be derived from qualitative differences in the patterns of item difficulty, and fast responses lead to a larger differentiation between items than slow responses do. 2. The abilities underlying fast and slow responses can also be differentiated, and fast responses allow for a better differentiation between the respondents.     

The effect of widening longitudinal road markings on driving speed perception

Road markings may influence driver behavior, and therefore road safety. An increase in the width of road markings might lead drivers to perceive lanes to be narrower than they really are, creating the illusion of traveling faster. The objective of this paper is to analyze whether wider longitudinal road markings can affect the perception of lane width and thus induce drivers to slow down. To this end, three curves with reduced visibility were selected for a field experiment. The road markings were painted wider than normal, and video recordings were made with narrow and wide markings by a camera installed in a vehicle. A total of 14 videos were shown to each of the 185 participants; then a survey was carried out to analyze in which video the participants perceived higher speed. The results showed that if the participants perceived differences in speed, the higher speed was perceived with the wide markings. This perception of higher speed increased if the participant was female, or if the participant had ever had an accident. In view of the obtained results, it can be said that the use of wider road markings could help reduce vehicle speed, thus contributing to improved road safety.     

Examining U.S. drivers’ characteristics in relation to how frequently they engage in speeding on freeways

Speeding and speed-related crashes have consistently represented over 25% of all traffic fatalities over the past two decades. The severity of these speed-related incidents not only impact the drivers but all road users. Thus, characterizing drivers who speed, understanding their motivations, and identifying the types of risky driving behaviors associated with speeding play a critical role in developing, implementing, and sustaining effective countermeasures. Using a survey administered to a U.S. nationally representative sample (N = 2,930 licensed drivers aged 16 or older), this study develops a partial proportional odds model to examine differences in characteristics between types of speeders – frequent, occasional, and non-speeders – and explores characteristics and risk driving behaviors that are most associated with speeding behavior. Additionally, motivations for speeding are examined for drivers who frequently speed compared with those who occasionally speed. Results show speeders tended to engage in other unsafe driving behaviors, such as distracted, aggressive, unbelted, and alcohol-impaired driving. Among demographic and socio-economic variables examined in this study, drivers’ age was the greatest associated determinant. The association with engagement in red-light running, however, outweighed that with drivers’ age. Interestingly, the interaction between educational attainment and engagement in aggressive driving was also predictive of speeding behavior. For motivations for speeding, frequent speeders were more likely to report enjoying driving fast and disagreeing with speed limits compared with occasional speeders. The findings of this study are useful towards identifying the various characteristics and behaviors of drivers who engage in speeding, which can provide future insights into where effective countermeasures and prevention efforts should be focused.     

Effect of speed on flow and enjoyment for driving and rollercoasters

Worldwide, road traffic injuries are the eighth highest cause of death, and campaigns targeting excessive speed are a common approach to tackling this issue. Yet one element missing from these campaigns is acknowledgment that speed is inherently enjoyable. This study of UK road users was designed to assess whether flow theory predicts the enjoyment of the sensation of speed in the contexts of road driving and riding a rollercoaster. In a repeated measures experimental design, participants viewed 5 first-person videos from a car-driver perspective under the conditions: congested traffic, 20 mph, 25 mph, 30 mph, 35 mph. As a counterpoint to road driving, comprising an experience designed for enjoyment of rapid speed, they also viewed 3 rollercoaster videos under the conditions: 0.5x normal speed, normal speed and 1.5x normal speed. Participants rated experience of flow and enjoyment after each video. Flow and enjoyment ratings were increased at faster speeds compared with slower speeds for the road and rollercoaster contexts. Sensation seeking moderated flow scores for road driving such that higher sensation seekers rated higher levels of flow at 20–35 mph, but not in congestion, compared with lower sensation seekers. Findings are consistent with a flow explanation of speeding, such that increased speed leads to increased flow experience. Sensation seekers may be more prone to such motivation to speed, although further research is needed to verify this. We recommend for enjoyment and flow to be considered in anti-speeding campaigns and for driving to be re-designed to facilitate flow at slower speeds.     

Guiding drivers towards safer driving speed: Exploiting visual dominance in speed adaptation

Inappropriate speed is a main cause of accidents. Drivers are often unaware of potential risks due to inadequate speed. To prevent dangerous situations, we need to understand perceptual factors influencing human speed perception. Due to the prominent role of vision in driving, we examined the effect of visuo-spatial stimuli on speed based on the optic flow. While developing an adaptive infrastructure measure to reduce speed, we conducted two consecutive studies, a driving simulator study and a field test to investigate findings further. In both studies, we placed lights on two sides of a highway exit and either illuminated them statically or activated them in a way that they appeared to be moving towards the driver. We expected drivers to slow down more when seeing static light stimuli compared to a baseline without lights. We also expected drivers to decrease speed more in conditions with oncoming lights compared to a baseline, and to static lights, due to distorted speed perception. The first study in a static driving simulator revealed no difference between conditions. In the field test, both static lights and lights moving towards the driver led to a speed reduction compared to a baseline but did not differ from one another. Lights in general led to lower driving speed, potentially due to their warning character, but we found no difference between the light conditions, suggesting that the effect might not be based on the optic flow. Future research should investigate the relationship between driven and perceived speed more closely.
