Psychosocial Factors in Child Safety Restraint Use1

Within the past 3 years, a majority of states have passed laws requiring children riding in automobiles to be properly restrained in safety devices. Several studies indicate that such laws have only a modest effect on the number of children being properly protected. To determine factors associated with safety restraint use a telephone interview survey was conducted with 211 residents of a state that has had a child safety restraint law in effect for two years. Several hypotheses derived from the Health Belief Model were tested. The model was generally supported, but will require some revision to explain a routine and repetitive behavior such as safety seat use. While strong general resistance to government intervention in family behavior was found, this did not translate into resistance of safety seat laws.     

The Motivating Potential of Leader Behaviors: A Comparison of Two Models1

The motivating potential of leader behaviors was investigated in a comparative test of two models relating leader behaviors, perceived role clarity, psychological influence, perceived self-competence, self-determination, and intrinsic motivation. Based on the data from 422 naval personnel and their immediate supervisors, it would appear that leaders' informational and controlling behaviors influence subordinates' perceptions of role clarity and psychological influence. Self-determination and self-competence also influence these perceptions. Psychological influence increases intrinsic motivation but role clarity influences intrinsic motivation only indirectly through its influence on psychological influence.     

A Comparison of Two Lateral Inhibitory Models of Metacontrast

Metacontrast, an apparent reduction in brightness of a target that is followed by a non-overlapping mask, has been modeled with simulated neural nets incorporating either recurrent lateral inhibition or forward and backward inhibition with lateral components. A one-layer lateral inhibitory model (B. Bridgeman, 1971, Psychological Review 78, 528-539) and a six-layer model (G. Francis, 1997, Psychological Review 104, 572-594) both simulate the basic metacontrast effect, showing that stimulus-dependent activity that reverberates for some time in the model after stimulus offset is essential to simulate metacontrast. The six-layer model does not simulate monotonic masking with low response criterion, an essential property of metacontrast; the lateral inhibitory model uses duration of reverberation to simulate the criterion. Each model simulates several variations of masking, such as changing the relative energy of target and mask, but neither can handle effects of practice or attention that apparently engage higher processing levels.

Predicting Adolescent Drinking From Alcohol Expectancy Values: A Comparison of Additive,Interactive, and Nonlinear Models1

Additive, interactive, and nonlinear models of alcohol expectancy values were compared using survey data from 1,758 high school students. Expectancies and values independently predicted drinking in the additive model. Expectancies were more important as predictors than were values, and negative expectancies were more important than positive expectancies. Significant expectancy-value interactions also were found. Drinking was highest when positive consequences were believed to be likely and desirable and was lowest when negative consequences were believed to be likely and undesirable. Significant nonlinearities indicated that beliefs about negative consequences had greater effects at lower levels of likelihood and evaluation whereas beliefs about positive consequences had greater effects at higher levels of likelihood and evaluation. However, the interactive and nonlinear effects were small.     

有限理性的"占优启发式"和"齐当别"决策模型的作为——当Allais悖论杠杆撬动了期望效用理论

人们在做决策时常常要受到时间或知识的限制,有时还要受到其双重限制。关于人们是如何进行风险决策,早期有期望效用理论对其加以解释,但Allais悖论对其标准化地位提出了挑战。Simon的“有限理性”观点提出后,一些研究者开始致力于开发决策的“有限理性”模型。文章讨论并比较了无限理性的期望效用理论被Allais悖论杠杆撬动之后,有限理性的“占优启发式”和“齐当别”决策模型所能做的和所不能做的。两种模型的决策标准、计算策略以及未来研究的展望也一并作了讨论。     

Predicting Citizen Support of Tax Increases for Education: A Comparison of Two Social Psychological Perspectives

A survey of citizen support of a proposal to increase property taxes for public education was conducted in a school district in Illinois. Two social psychological perspectives predicting support were tested. One perspective, derived from social exchange theory, predicted that citizens would base their support of or opposition to a tax increase primarily on perceived self-interested economic gain or loss. A second perspective predicted that non-self-interested concerns, such as attitudes toward the schools, would determine support of or opposition to a tax increase. Although both models received support, the strongest and mat consistent predictors of tax support among those most likely to be voters were the non-self-interested factors. Implications of these findings for public policy and for understanding political behavior are discussed.     

An Examination of the Determinants of Intention and Behavior: A Comparison of Two Models

Two behavioral prediction models were compared. The behavior used was church attendance, and the models used were those proposed by Triandis (1977) and Fishbein (Fishbein & Ajzen, 1975). The results indicated that both models were effective in the prediction of intention and behavior. However, while Triandis' model accounted for a greater percent of the variance in the prediction of intention, Fishbein's model did better in predicting behavior.     

Predicting Condom Use in African American STD Patients: The Role of Two Types of Outcome Expectancies1

This study examined the association of two types of condom use outcome expectancies (self-approval and partner reaction) with patterns of safer sexual behavior among predominantly African American patients at a sexually transmitted diseases (STD) clinic. As expected, both individuals' own self-approval outcome expectancies and their partner reaction outcome expectancies predicted consistency of condom use, although partner reaction expectancies predicted condom use above and beyond the effects of self-approval expectancies. Furthermore, individuals who believed that they and their partner shared positive condom use outcome expectancies reported the greatest use of condoms. These findings suggest that HIV prevention programs should address both types of condom use outcome expectancies in order to maximize behavior change.     

Residential Water Use: Predicting and Reducing Consumption1

This project had two goals: to explain variation in residential water consumption and to evaluate methods of encouraging residents to reduce their consumption. Survey data for both studies were collected by mail questionnaire in early 1991, and water consumption figures were recorded between June and August of that year. In Study 1 (n = 264) a three-variable regression model (number of residents, clothes washing machine loads, and property value) accounted for 60% of the variance. Attitudes, habits and values were very poor predictors of water consumption. In Study 2 (n =226) households were divided into three treatment groups: feedback only, feedback and dissonance, and a control group. Repeated-measures ANOVA revealed that high consumers receiving dissonance and feedback or feedback alone had significantly reduced their water consumption in the treatment period. The implications of these findings are discussed.     

Predicting Undergraduate Condom Use with the Fishbein and Ajzen and the Triandis Attitude-Behavior Models: Implications for Public Health Interventions1

The present study used two social-psychological theories of attitude-behavior relationships to investigate condom use by college undergraduates. One purpose of the present research is to provide information for public health practitioners to better design theory-based interventions to reduce the incidence of STD's by increasing the use of condoms. Another purpose is to compare the relative usefulness of two attitude-behavior models in predicting condom use. The Fishbein and Ajzen theory of reasoned action (Ajzen, 1988; Fishbein & Ajzen. 1980) was compared with a version of Triandis' theory of attitude-behavior relations (Triandis, 1977). Of major interest was whether variables in this version of the Triandis model increased the explanatory power of the Fishbein and Ajzen model in the prediction of condom use intention and behavior. In addition, specific outcome beliefs and normative beliefs held by subjects were used to predict condom use. One hundred and ninety college undergraduates were given a questionnaire designed to measure the components of the two models. Three months after completing the questionnaire, subjects were contacted by phone to record the subject's frequency of condom use (if the subject reported having had intercourse) during the 3-month period between initial assessment and follow-up. In the prediction of intention to use a condom, results indicate that one variable from the Triandis model, personal normative beliefs, increases the explanatory power offered by the expectancy value and normative belief components of the Fishbein and Ajzen model. In the prediction of reported condom use during the 3-month follow-up period, two variables from the Triandis model—perceived susceptibility and AIDS fear—significantly increased the predictive power of the Fishbein and Ajzen model. Based on these results, the authors propose an alternative model to explain undergraduate condom use. The implications of these findings for public health interventions to encourage the use of condoms is discussed.     

Juror Selection: A Comparison of Two Methods In Several Criminal Cases1

Ethical and constitutional issues have been raised by critics concerning the intervention of social science methods in the voir dire, pretrial, screening of prospective jurors. An experiment was conducted to compare the effectiveness of conventional jury selection methods utilized by attorneys (past experience, intuition, folklore) vs. systematic social science methods (systematic identification of predictive relationships among personality, demographic, and attitudinal variables). The comparison was made over four separate criminal cases. The data indicated that in cases in which the predictive relationships used by the systematic social science methods were relatively strong, this method is superior to the conventional method in predicting favorable jurors' responses. The more intuitive conventional niethod was superior when the critical predictive relationships were weak or absent. Overall, the systematic social science method was not superior to the conventional method. Issues of ecological validity and pretrial discovery rules were discussed.     

Constraints on Analogical Mapping: A Comparison of Three Models

Three theories of analogy have been proposed that are supported by computational models and data from experiments on human analogical abilities. In this article we show how these theories can be unified within a common metatheoretical framework that distinguishes among levels of informational, behavioral, and hardware constraints. This framework clarifies the distinctions among three computational models in the literature: the Analogical Constraint Mapping Engine (ACME), the Structure-Mapping Engine (SME), and the Incremental Analogy Machine (IAM). We then go on to develop a methodology for the comparative testing of these models. In two different manipulations of an analogical mapping task we compare the results of computational experiments with these models against the results of psychological experiments. In the first experiment we show that increasing the number of similar elements in two analogical domains decreases the response time taken to reach the correct mapping for an analogy problem. In the second psychological experiment we find that the order in which the elements of the two domains are presented has significant facilitative effects on the ease of analogical mapping. Of the three models, only IAM embodies behavioral constraints and predicts both of these results. Finally, the immediate implications of these results for analogy research are discussed, along with the wider implications the research has for cognitive science methodology.     

Individual Restraint and Group Efficiency in Commons Dilemmas: The Effects of Two Types of Environmental Uncertainty1

In most real-world commons, the exact resource quantity is rarely known, and the rate at which the resource regenerates is not always predictable. Annual salmon runs, for example, are based on breeding rates and many other factors; those fishing never know exactly how many fish will be available for next year's season. The present study employed a computerized commons dilemma simulation to investigate the impact of uncertainty in pool size and regeneration rate on individuals harvest choice and the efficiency with which groups managed the resource pool. Both types of uncertainty produced significant declines in individual restraint and group efficiency, although the group-level effects tended to be stronger than those at the individual level. Implications for the management of real-world commons are discussed.     

Psychometric Validation of the Temptation and Restraint Inventory in Two Samples of College Drinkers1

Drinking restraint, commonly measured by the Temptation and Restraint Inventory (TRI; Collins & Lapp, 1992), refers to a cycle of temptation to drink alcohol and attempts to control alcohol use that results in excessive consumption. Recent research has examined college drinkers using the TRI, however, it has been validated only in adult samples. This study validated the TRI in two samples of college drinkers, designated as “hazardous” (n = 480) and “harmful” (n = 231) drinkers. Using confirmatory factor analysis, the previously reported higher order two-factor structure was identified in both samples. In addition, multiple regression analyses using derived component scores demonstrated that TRI performance was associated with degree of alcohol dependence in both samples. These data support the use of the TRI in college samples.These data were previously presented in November 2002 at the 36th annual meeting of the Association for the Advancement of Behavior Therapy, Reno, NV     

Activation and Use of Racial Stereotypes in Personnel Decisions: A Test of Two Theories1

This research tested contrasting predictions about activation and use of racial stereotypes in personnel decisions. Devine's (1989) theory' holds that stereotyped inferences should be apparent when decisions are time constrained and judges have little opportunity to suppress automatically activated stereotypes. Gilbert & Hixon's (1991) busy-ness model implies that stereotypes are unlikely to be activated and to influence the decisions of judges unless these decisions are not time-constrained. Participants were allowed 90 s or 180 s to evaluate Black and White candidates for football managerial positions requiring aggressiveness (linebacker coach) or cognitive prowess (general manager). Only when decisions were not time constrained did participants show stereotyped judgments by favoring Whites for the general manager's position and overranking Blacks for linebacker coach. This pattern was consistent with Gilbert & Hixon's busy-ness model and contrary to Devine's theory of automatically activated stereotypes.     

Social Contact,Loneliness, and Mass Media Use: A Test of Two Hypotheses1

The possible connections between social variables such as frequency of social activity and subjective loneliness on the one hand, and extent of mass media use on the other, have received relatively little empirical attention. In this investigation, two related hypotheses concerning such links are proposed. The compensation hypothesis holds that persons with little social contact or greater loneliness will be more likely to utilize mass media to compensate for social impoverishment. The buffering hypothesis more specifically predicts that such compensation is effective; that is, persons “at risk” for loneliness because of diminished social contact may be at least partially protected from subjective loneliness due to heavy use of mass media. The hypotheses were tested in two samples: college students and a group of adolescent males attending a summer camp. Little support was found for the compensation hypothesis. While limited support was found for the buffering hypothesis, analyses also revealed an unexpected opposite effect; for the music variable, heavy media use actually intensified the association between social deficits and subjective loneliness. Some limitations of this study are discussed, and issues related to the unexpected “intensification” effects are presented.
