Developmental research often involves studying change across 2 or more processes or constructs simultaneously. A natural question in this work is whether change in these 2 processes is related or independent. Associative latent transition analysis (ALTA) was designed to test hypotheses about the degree to which change in 2 discrete latent variables is related. The ALTA model is a type of latent class model, which is a categorical latent variable model based on categorical indicators. In the ALTA approach, level and change on 1 variable is predicted by level and change in another. Two types of hypotheses are discussed: (a) broad hypotheses of dependence between the 2 discrete latent variables and (b) targeted hypotheses comparing specific patterns of change between levels of the discrete variables. Both types of hypotheses are tested via nested model comparisons. Analyses of relations between psychological state and substance use illustrate the model. Recent psychological state and recent substance use were found to be associated cross-sectionally and longitudinally, implying that change in recent substance use was related to change in recent psychological state.  相似文献

We extend prior research on involvement in employee development activity by including prominent individual difference constructs that have been previously ignored in this area of research. These include two important personality characteristics (conscientiousness and openness to experience), mental ability and goal orientation constructs. We tested both mediated and direct effects of the variables. The sequence of relationships observed in the model was: general personality traits → development domain individual and situational variables → development domain motivational variables → involvement in development. Personality had indirect (mediated) effects on motivational and involvement constructs while goal orientation, as a development domain individual variable, had direct effects on motivational constructs. Mental ability had no effects. The study also replicated core relationships from prior research, but did so using an Internet sample and response medium. The model presented provides the most complete picture of behavior in this area to date. Important implications for advancement of theory, research and practice in the area of employee development behavior are discussed.  相似文献

Previous findings have shown that some reactions (e.g. satisfaction with feedback) are guided by self‐enhancement theory, whereas other reactions (e.g. perceived feedback accuracy) have been shown to follow predictions of self‐consistency theory. The Integrative Self‐Schema Model (ISSM) assumes that these effects should be moderated by the elaboration of the self‐schema involved: This assumption was tested in an experimental study: 72 participants received fictitious feedback on different personality dimensions allegedly based on an adjective checklist. This feedback was either consistent with self‐perceptions, more positive than expected, or more negative than expected, and addressed highly elaborated (schematic) or less elaborated (aschematic) personality dimensions. Satisfaction, feedback accuracy and interest in further information were analysed as dependent variables. The experimental results clearly confirmed the hypotheses derived from the ISSM for satisfaction and perceived feedback accuracy. A self‐consistency effect regarding perceived feedback accuracy was found only for feedback on schematic dimensions but was attenuated on aschematic dimensions. A self‐enhancement effect regarding satisfaction was found only on aschematic dimensions. This finding was reversed on schematic dimensions. Finally, interest in further information did not follow the predictions made by the ISSM. Copyright © 1999 John Wiley & Sons, Ltd.  相似文献

In this study, by using the hypotheses of social‐cognitive career theory (SCCT), the relationship between informative sources of math‐related self‐efficacy expectations and self‐efficacy, interest, and math‐weighted major preferences were investigated. The participants in this study were students (N = 590) from high schools in Southern Turkey. Participants completed measures of sources of math‐related self‐efficacy, self‐efficacy, interest, and choice consideration related to math‐weighted majors. While running analyses, sampling was split in half at random and psychometric analyses of the scales were run with the first half (n = 298); the second half (n = 292) was used to test the hypotheses. By doing this, the testing of hypotheses would not be affected by just one specific sampling characteristic. A structural equation model was tested and findings indicated general support for hypotheses that these sources predict self‐efficacy beliefs and these beliefs also predict interest. However, contrary to SCCT's predictions, math‐weighted major preferences are not predicted by math‐related self‐efficacy expectations and interest. In the Discussion, first, the reasons why the measurement of vicarious learning or modelling did not significantly predict self‐efficacy expectations focus on the relationships between personal accomplishments and persuasion and reported physiological arousal and personal accomplishments. Some information is given as to how counsellors and math teachers can work collaboratively to raise perceptions about informative sources. Second, explanations are given about why self‐efficacy and interest did not predict math‐weighted preferences. It is mentioned that this could be the reason for the constrained and complex system of the university entrance exams and placement in Turkey. The importance of investigating environmental variables on SCCT in developing countries was emphasized. Suggestions are also given for further research. It is concluded that this theory should be tested in developing countries like Turkey.  相似文献

The authors describe the effects of practice conditions in motor learning (e.g., contextual interference, knowledge of results) within the constraints of 2 experimental variables: skill level and task difficulty. They use a research framework to conceptualize the interaction of those variables on the basis of concepts from information theory and information processing. The fundamental idea is that motor tasks represent different challenges for performers of different abilities. The authors propose that learning is related to the information arising from performance, which should be optimized along functions relating the difficulty of the task to the skill level of the performer. Specific testable hypotheses arising from the framework are also described.  相似文献

General Strain Theory’s (GST) mediating and conditioning hypotheses suggest that emotions mediate the strain-crime relationship and that personality traits condition the effects of strain. Individual-level research provides weak-to-mixed support for these hypotheses, leading to calls to revise GST. Yet, the mediating and conditioning hypotheses provide situational predictions which are largely untested at the situational-level. Further, Agnew (2013) recently suggested a modified method of testing the conditioning hypothesis. This research, using factorial survey data from 734 college students, presents a situational test of this revised version of GST. Results are generally, but not fully, supportive of the mediating and conditioning hypotheses. This indicates that Agnew’s most recent theoretical revision may be better suited for capturing the conditioning effect and that it is important to conduct more situational research on GST.  相似文献

Background. The trans‐contextual model (TCM) is an integrated model of motivation that aims to explain the processes by which agentic support for autonomous motivation in physical education promotes autonomous motivation and physical activity in a leisure‐time context. It is proposed that perceived support for autonomous motivation in physical education is related to autonomous motivation in physical education and leisure‐time contexts. Furthermore, relations between autonomous motivation and the immediate antecedents of intentions to engage in physical activity behaviour and actual behaviour are hypothesized. Aims. The purpose of the present study was to incorporate the constructs of basic psychological need satisfaction in the TCM to provide a more comprehensive explanation of motivation and demonstrate the robustness of the findings of previous tests of the model that have not incorporated these constructs. Sample. Students (N=274) from Greek secondary schools. Method. Participants completed self‐report measures of perceived autonomy support, autonomous motivation, and basic psychological need satisfaction in physical education. Follow‐up measures of these variables were taken in a leisure‐time context along with measures of attitudes, subjective norms, perceived behavioural control (PBC), and intentions from the theory of planned behaviour 1 week later. Self‐reported physical activity behaviour was measured 4 weeks later. Results. Results supported TCM hypotheses. Basic psychological need satisfaction variables uniquely predicted autonomous motivation in physical education and leisure time as well as the antecedents of intention, namely, attitudes, and PBC. The basic psychological need satisfaction variables also mediated the effects of perceived autonomy support on autonomous motivation in physical education. Conclusions. Findings support the TCM and provide further information of the mechanisms in the model and integrated theories of motivation in physical education and leisure time.  相似文献

Abstract.— A hypothesis-sampling theory for rule learning predicts that only those rules that are available for sampling can be learned. Earlier results show that subjects have a very limited set of hypotheses about rules relating scaled cue and criterion variables, consisting mainly of linear and symmetric quadratic functions, but not of complex functions, such as J-shaped rules. Tasks requiring the use of such rules should, therefore, not be learned. The results of the present experiment show, however, that subjects are able to find J-shaped relations. The results were interpreted to mean that subjects are able to construct hypotheses, and that they are not limited to sampling of hypotheses from a preestablished set of possible hypotheses.  相似文献

The tendency to test outcomes that are predicted by our current theory (the confirmation bias) is one of the best‐known biases of human decision making. We prove that the confirmation bias is an optimal strategy for testing hypotheses when those hypotheses are deterministic, each making a single prediction about the next event in a sequence. Our proof applies for two normative standards commonly used for evaluating hypothesis testing: maximizing expected information gain and maximizing the probability of falsifying the current hypothesis. This analysis rests on two assumptions: (a) that people predict the next event in a sequence in a way that is consistent with Bayesian inference; and (b) when testing hypotheses, people test the hypothesis to which they assign highest posterior probability. We present four behavioral experiments that support these assumptions, showing that a simple Bayesian model can capture people's predictions about numerical sequences (Experiments 1 and 2), and that we can alter the hypotheses that people choose to test by manipulating the prior probability of those hypotheses (Experiments 3 and 4).  相似文献

Political skill is a social effectiveness construct with a demonstrated capacity to predict job performance. However, because performance prediction research in this area to date has made exclusive use of self‐reports of political skill, and due to frequent distrust of self‐ratings of constructs in important personnel decisions, there is a need to investigate how multiple alternative sources of political skill and job performance measures relate, thus raising both theoretical and methodological issues. In three studies, employing a triadic data collection methodology, and utilising both cross‐sectional and longitudinal designs, this research tested the hypotheses that employee political skill, measured from the perspective of employees' assessor A, will positively predict job performance rated by assessor B (i.e. Hypothesis 1a), and vice versa, that employee political skill measured by assessor B will predict job performance ratings measured by assessor A (i.e. Hypothesis 1b).  相似文献

This article is a nontechnical introduction to the use of structural equation models in personality research Although such models can be fruitfully used to address a variety of important theoretical issues, the substantive focus in this article is on the use of such models for elucidating the construct validity of personality measures We include numerous more specific topics under our treatment of construct validity First of all, we show how structural equation models can be applied to the issues of convergent and discriminant validity Do our variables measure the constructs we want them to measure and not other constructs that we would prefer not to measure? Second, we show the utility of structural equation models for predictive validity Do our variables reliably predict other constructs with which they are theoretically linked? Finally, we examine the stability of personality constructs through structural equation models Through-out, our emphasis is on the particular advantages that structural equation models bring to these analytic tasks Ultimately, such models must be used in the service of theory, and when used appropriately, they can help us to refine both our measures and our theories of individual differences  相似文献

We examined relations between the environmental dimensions underlying Holland's theory of vocational choice and skill requirements, context characteristics, and task frequency ratings for managerial jobs. The Holland environmental constructs were measured by the recently developedPosition Classification Inventory(PCI). The task, skill requirement, and context variables were measured using traditional job analysis surveys. Ten judges provided estimates of the expected correlations between the job analysis variables and the Holland constructs. The profile of observed correlations was generally consistent with the judges’ expectations based on Holland's theory, providing support for both that framework and the construct validity of the PCI. The one Holland dimension for which the data were least consistent with predictions was “Realistic.” Results provide a detailed picture of the work content, skills, and context variables within managerial work that are likely to be associated with the RIASEC dimensions. Implications for management development are discussed.  相似文献

This study examined gender differences in a large-scale assessment center for officer entry in the British Army. Subgroup differences were investigated for a sample of 1,857 candidates: 1,594 men and 263 women. A construct-driven approach was chosen (a) by examining gender differences at the construct level, (b) by formulating a priori hypotheses about which constructs would be susceptible to gender effects, and (c) by using both effect size statistics and latent mean analyses to investigate gender differences in assessment center ratings. Results showed that female candidates were rated notably higher on constructs reflecting an interpersonally oriented leadership style (i.e., oral communication and interaction) and on drive and determination. These results are discussed in light of role congruity theory and of the advantages of using latent mean analyses.  相似文献

This study examined whether items from a biodata inventory were consistent with theory‐based constructs as suggested by the ecology model. The model posits five constructs explain biodata predictive ability. Items were sorted using the theory‐based construct domains. The resulting scale scores were assessed for evidence of content, criterion‐related, and construct validity in a sample of 6032 automated systems controllers. Results suggested moderate support for the theory‐based constructs. A notable finding was that items capturing a theoretical construct were impacted by the life stage in which they were anchored. Results further suggest the need to examine if certain life stages are more predictive than others or perhaps if certain constructs are more predictive when related to a particular life stage.  相似文献

This research tested hypotheses for a mechanism by which low perceived support may lead to psychological distress. According to social‐cognitive models, perceived support guides the interpretation of interpersonal situations. People with low perceived support interpret these situations more negatively than do people with high perceived support, and these negative interpretations lead to psychological distress. This mechanism is hypothesized to be distinct from similar mechanisms involving other social‐cognitive constructs, such as dysfunctional attitudes. These hypotheses were tested in 2 samples of adults adjusting to divorce. The data were consistent with predictions. Implications for understanding low perceived support's relation to distress and adults' adjustment to divorce were discussed.  相似文献

Individual differences in uncertainty have been associated with heightened anxiety, stress and approach-oriented coping. Intolerance of uncertainty (IU) is a trait characteristic that arises from negative beliefs about uncertainty and its consequences. Researchers have established the central role of IU in the development of problematic worry and maladaptive coping, highlighting the importance of this construct to anxiety disorders. However, there is a need to improve our understanding of the phenomenology of IU. The goal of this paper was to present hypotheses regarding the similarities and differences between IU and three related constructs – intolerance of ambiguity, uncertainty orientation, and need for cognitive closure – and to call for future empirical studies to substantiate these hypotheses. To assist with achieving this goal, we conducted a systematic review of the literature, which also served to identify current gaps in knowledge. This paper differentiates these constructs by outlining each definition and general approaches to assessment, reviewing the existing empirical relations, and proposing theoretical similarities and distinctions. Findings may assist researchers in selecting the appropriate construct to address their research questions. Future research directions for the application of these constructs, particularly within the field of clinical and health psychology, are discussed.  相似文献

Replies to comments on the current authors' original article. S. Ghetti (2008) and M. L. Howe (2008) presented probative ideas for future research that will deepen scientific understanding of developmental reversals on false memory and establish boundary conditions for these counterintuitive patterns. Ghetti extended the purview of current theoretical principles by formulating hypotheses about how developmental reversals are controlled by the growth of phantom recollection and by the growth of false-memory editing. Some data are available on her hypotheses about phantom recollection, which distinguish phenomenology (vague or vivid) from memory representation (verbatim or gist). Howe introduced alternative theoretical principles that can be traced to the early work of Deese and Underwood. He argued that fuzzy-trace theory is subject to 3 limitations and that his alternative conception makes 3 predictions that contrast with fuzzy-trace theory's predictions. In the current reply, it is shown that the stated limitations do not apply to fuzzy-trace theory, that previously published research runs counter to the 3 predictions, and that the core difference between the 2 approaches is that fuzzy-trace theory is an opponent-processes model whereas the alternative conception is a 1-process model.

While the constructs of aplitude and achievement, which are here defined as genotypic and environmental constructs, are potentially useful in psychological theory and in the development of predictors and weights for predictors, the use of these terms for psychological tests is highly misleading. When used for tests, the terms lead to invalid inferences concerning the constructs and to erroneous predictions of later criteria. All psychological tests measure current performance levels which are phenotypic characteristics. Practically all such tests can be used to estimate both genotypic and environmental constructs with nonzero accuracy. The basic error is to use a term which denotes a genetic or an environmental construct for a phenotypic measure. Implications of this position for inferences concerning group differences in aptitude and for construct validity of tests are briefly discussed.  相似文献
