The Natural History of Cigarette Smoking: Predicting Young-Adult Smoking Outcomes From Adolescent Smoking Patterns

Assessed the magnitude of risk that adolescent cigarette smoking carries for adult smoking. Using a longitudinal, prospective design, results indicate that even infrequent experimentation in adolescence significantly raises the risk for adult smoking and that regular (at least monthly) adolescent smoking raises the risk for adult smoking by a factor of 16 compared to nonsmoking adolescents. Relative risk was also increased by an early onset of smoking and by a stable, uninterrupted course from experimentation to regular smoking. Relative risk did not significantly vary by age or sex. The continuity of smoking behavior between adolescence and adulthood supports the importance of primary prevention programs directed at adolescent populations.

Changes in Peer and Parent Influence During Adolescence: Longitudinal Versus Cross-Sectional Perspectives on Smoking Initiation

The current study used a longitudinal design to investigate age-related changes in the magnitude of peer and parent influences on adolescent cigarette smoking. Both peer and parent influences were significant predictors of subsequent transitions to higher levels of smoking. However, unlike previous cross-sectional research, the magnitude of peer and parent influences did not significantly vary across the 6thto 1 lth-grade levels. Additional analyses were undertaken to explore possible explanations for the differences between results produced by cross-sectional and longitudinal approaches. Implications for the study of transitions across the life span are discussed.

Updating after Rotational and Translational Body Movements: Coordinate Structure of Perspective Space

As people move through an environment, they typically change both their heading and their location relative to the surrounds. During such changes, people update their changing orientations with respect to surrounding objects. People can also update after only imagining such typical movements, but not as quickly or accurately as after actual movement. In the present study, blindfolded subjects pointed to objects after real and imagined walks. The role of rotational and translational components of movement were contrasted. The difficulty of imagined updating was found to be due to imagined rotation and not to imagined translation; updating after the latter was just as quick and accurate as updating after actual rotations and translations. Implications for understanding primary spatial orientation, the organization of spatial knowledge, and spatial-imagination processes are discussed.

Building spatial representations through primary and secondary learning.

The current study examined the conditions under which cognitive representations of spatial information are stored in orientation-specific ways (like pictures) versus orientation-free ways. College students learned simple paths by viewing a map of them (map condition), by walking them while blindfolded (walk condition), or by directly viewing the route from a single vantage point (look condition). Blindfolded subjects then stood on the route in various orientations and made directional judgments to other locations on the route. When subjects learned the route by indirect, symbolic means (map), judgments were quite easy when aligned with the learned map orientation and were difficult if the judgment was not aligned with the learned map orientation. However, when subjects learned the route by more direct, primary spatial learning (walk or look), there were no alignment effects. Thus, subjects treat information from primary (direct) and secondary (symbolic) spatial learning in distinct ways. Learning from a map results in a figural representation that has great precision but a specific orientation. Learning the route more directly results in a representation that is less precise but one that can be used in more flexible ways.

PROSPECTIVE PREDICTORS OF QUIT ATTEMPTS AND SMOKING CESSATION IN YOUNG ADULTS

This study examined prospective predictors of attempts to quit smoking and successful quitting among those who attempted to quit (n = 700), using a long-term longitudinal study of the natural history of cigarette smoking in a midwestern community sample. Participants, originally surveyed in 6th-12th grade (1980-1983), were followed up in 1987 and 1994. Results showed that amount of smoking, gender, education, health beliefs about smoking, value on healthy lifestyle, motives for smoking, reasons for quitting, and occupancy of young adult social roles were significant predictors of cessation. However, there were different predictors of attempts to quit and successful quitting among those who attempted to quit. From a public health perspective, both predictors of quit attempts and predictors of successful quitting among attempters are useful targets for intervention.

Orientation specificity in spatial memory: What makes a path different from a map of the path?

Three studies investigated the factors that lead spatial information to be stored in an orientation-specific versus orientation-free manner. In Experiment 1, we replicated the findings of Presson and Hazelrigg (1984) that learning paths from a small map versus learning the paths directly from viewing a world leads to different functional characteristics of spatial memory. Whether the route display was presented as the path itself or as a large map of the path did not affect how the information was stored. In Experiment 2, we examined the effects of size of stimulus display, size of world, and scale transformations on how spatial information in maps is stored and available for use in later judgments. In Experiment 3, we examined the effect of size on the orientation specificity of the spatial coding of paths that are viewed directly. The major determinant of whether spatial information was stored and used in an orientation-specific or an orientation-free manner was the size of the display. Small displays were coded in an orientation-specific way, whereas very large displays were coded in a more orientation-free manner. These data support the view that there are distinct spatial representations, one more perceptual and episodic and one more integrated and model-like, that have developed to meet different demands faced by mobile organisms.

Four pathways to young-adult smoking status: adolescent social-psychological antecedents in a midwestern community sample.

Evaluated the ability of social-psychological factors, measured in adolescence, to predict young-adult smoking outcomes. Results showed substantial continuity in the antecedents of adolescent and young-adult smoking but important discontinuities as well. Beliefs in the negative social consequences of smoking and beliefs about academic success and independence were important to adolescent but not to adult smoking. Conversely, beliefs in the negative health consequences of smoking were more important to adult smoking than to adolescent smoking. Results also showed an appreciable amount of smoking onset after the high school years, as well as an appreciable amount of adolescent smoking that did not persist into young adulthood. Antecedents of late-onset smoking and of nonpersistent smoking are described.

Social Psychological Contributions to the Understanding and Prevention of Adolescent Cigarette Smoking

The purpose of this article is to illustrate the contributions of basic theory and research in social psychology to our understanding of an important public health problem - adolescent cigarette smoking -and to smoking prevention. The authors describe how social psychological theory and research have enabled us to better understand the processes underlying adolescent smoking adoption and to devise more effective intervention programs to deter adolescent smoking.

Orientation-specificity in kinesthetic spatial learning: The role of multiple orientations

In the current study we tested whether multiple orientations in kinesthetic learning affected how flexibly spatial information is stored and later used in making location judgments. Three groups learned simple routes by walking them while blindfolded, with (1) multiple orientations achieved through normal walking, (2) multiple orientations achieved through backward walking, or (3) a single orientation achieved through walking without turning (which required forward, backward, and sideways walking). When subjects had experienced multiple orientations while learning the routes, later directional judgments were equally accurate (and equally rapid) regardless of whether the judgments were aligned or were contra-aligned with the orientation of the routes as originally learned. In contrast, when routes were learned in a single orientation (without turning), subsequent judgments on contra-aligned trials were both less accurate and slower than judgments on aligned trials. Thus, multiple orientations are important to establish orientation-free, flexible use of spatial information in a kinesthetic learning environment. This contrasts with the pattern of results typically found in visual spatial learning and suggests that the factors that affect orientation specificity of spatial use may differ across spatial modality.

From adolescence to adulthood: age-related changes in beliefs about cigarette smoking in a midwestern community sample.

The current study used a cohort-sequential design to examine age-related changes in health-relevant beliefs from the middle school years through age 37 in a large, midwestern, community sample (N=8,556). Results suggest systematic age-related changes such that beliefs in the personalized risks of smoking declined in middle school and then increased, beliefs in generalized health risks increased beginning in the middle school years, and values placed on health as an outcome decreased in the high school years and then increased. These findings suggest that intervention programs must counter declining personalized risk perceptions among middle school students and declining values placed on health among high school age students.
