The effect of motive-goal congruence on adolescents’ academic goal engagement and disengagement

Motivation and Emotion - Academic achievement is an important developmental goal during adolescence. Two independent factors involved in academic motivation are implicit motives and explicit goals....     

Receiving Two Consequences: Tests of Monotonicity and Scale Invariance

The present study investigated two behavioral properties of decision making. Participants were presented two alternatives, each of which yielded two consequences jointly (joint receipt, JR). Monotonicity of JR states that choices remain invariant when the same lottery is adjoined to both of the original alternatives. The data failed to reject monotonicity of JR. Scale invariance states that choices remain invariant under proportionate (scale) changes of the lottery consequences. This property was not rejected for three of four classes of JR lotteries having a common consequence, but it was rejected for two of three classes of binary lotteries and for two of the four classes of general JR lotteries. We conclude that scale invariance does not hold in general. The implication of these findings for utility theory, testing its fundamental assumptions, and determining the functional form of utility is discussed. Copyright 2000 Academic Press.     

Parameter estimation of multiple item response profile model

Multiple item response profile (MIRP) models are models with crossed fixed and random effects. At least one between-person factor is crossed with at least one within-person factor, and the persons nested within the levels of the between-person factor are crossed with the items within levels of the within-person factor. Maximum likelihood estimation (MLE) of models for binary data with crossed random effects is challenging. This is because the marginal likelihood does not have a closed form, so that MLE requires numerical or Monte Carlo integration. In addition, the multidimensional structure of MIRPs makes the estimation complex. In this paper, three different estimation methods to meet these challenges are described: the Laplace approximation to the integrand; hierarchical Bayesian analysis, a simulation-based method; and an alternating imputation posterior with adaptive quadrature as the approximation to the integral. In addition, this paper discusses the advantages and disadvantages of these three estimation methods for MIRPs. The three algorithms are compared in a real data application and a simulation study was also done to compare their behaviour.     

How does education lead to healthier behaviours? Testing the mediational roles of perceived control,health literacy and social support

Abstract

Objectives: Educational attainment is increasingly recognised as a unique dimension of socioeconomic status (SES) and a powerful determinant of health behaviour—and thus physical health and mortality. However, very little is known about the specific pathways through which education influences these health behaviours. Design: The present study used a nationally representative US survey to test three potential psychosocial pathways (perceived control, health literacy and social support) through which education might influence intake of fruits and vegetables (FV), physical activity (PA) and sedentary behaviour (SB), controlling for other aspects of SES (income, health insurance status) and demographics (age, gender, race/ethnicity). Results: Both aspects of perceived control (locus of control, cancer fatalism) mediated the impact of education on FV and PA while only locus of control mediated the impact of education on SB. Further, only one aspect of health literacy (ability to understand recommendations) mediated education’s effect on any health behaviour (FV). Social support did not mediate any of the effects of education on health behaviors. Conclusion: Future work explicitly assessing and testing these mediational pathways is needed to better understand how education influences people’s health behaviours throughout their lives.     

The roles of encoding strategies and retrieval practice in test-expectancy effects

We investigated whether expectations for different kinds of memory tests induce qualitatively different encoding strategies. In Experiment 1, participants studied four lists of words and after each list completed a cued-recall test that contained either all semantic or all orthographic cues so as to build up an expectancy for receiving the same type of test for the fifth critical study list. To rule out that the test-expectancy effects in Experiment 1 were due to differences in retrieval practice, in Experiment 2, participants received three practice tests each for both cue-types. Participants’ test expectancy for all lists was induced by telling them before each list the type of cue they would receive for the upcoming study list. In both experiments, the critical test contained both expected and unexpected cues. In Experiment 1, participants who expected semantic cues had better recall to the semantic cues than to the orthographic cues and vice versa for those who expected orthographic cues. However, in Experiment 2, there was no effect of test expectancy. These findings suggest that the test-expectancy effects in Experiment 1 were due to more retrieval practice on the expected than unexpected tests rather than to qualitatively different test-expectancy-induced encoding strategies.

Depression Moderates the Relationship between Body Image and Health-Related Quality of Life in Adolescent Girls

Body image can predict health-related quality of life (HRQoL) in adolescent girls through self-esteem and psychological well-being. Additionally, depression is a significant predictor of adolescents’ HRQoL and is associated with body image. Therefore, we investigated whether the relationship between body image and HRQoL in adolescent girls is moderated by depression. In this cross-sectional study, adolescent girls’ body image, depression, and HRQoL (n?=?385, age: 12–15 years) were measured through self-report questionnaires. Multiple regression and simple slope analyses were conducted to examine the moderating effect of depression. Body image was positively correlated with HRQoL, whereas depression was negatively correlated with body image and HRQoL. Body image, depression, and their interaction explained 44.9% of the variance in HRQoL. Simple slope analysis showed that a more positive body image was associated with higher HRQoL among adolescent girls without depressive symptoms, but was not significantly related to HRQoL for adolescents with depressive symptoms. The moderating effect of depression was confirmed. In conclusion, screening for depression is recommended for adolescent girls prior to implementing body image interventions in schools and the community that are aimed at improving HRQoL. Furthermore, health care providers in schools and the community should provide psychological support for depression along with body image interventions to improve the HRQoL of girls in schools and the community. In particular, for girls with depressive symptoms, depression management should be conducted beforehand.     

Correspondence effects for objects with opposing left and right protrusions

Choice reactions to a property of an object stimulus are often faster when the location of a graspable part of the object corresponds with the location of a keypress response than when it does not, a phenomenon called the object-based Simon effect. Experiments 1-3 examined this effect for variants of teapot stimuli that were oriented to the left or right. Whether keypress responses were made with fingers within the same hand or between different hands was also manipulated. Experiment 1 showed that, for judgments of stimulus color and upright-inverted orientation, the Simon effect for intact teapots occurred in the direction of the spout location and was larger for within- than between-hand response modes. In Experiments 2 and 3, teapots with the handle or spout removed showed separate contributions of each component to the Simon effect. In Experiment 4, we clarified a discrepancy between our findings of object-based Simon effects and a previously reported absence of effect with color judgments for door-handle stimuli. We obtained an object-based Simon effect with respect to handle position when the bases of the door handles were centered but not when the handles were centered. The findings that object-based Simon effects occur with color judgments and when responses are fingers on the same hand are in closer agreement with a location coding account than with a grasping affordance account.     

Mindful attention predicts greater recovery from negative emotions,but not reduced reactivity

This study investigated the role of dispositional mindful attention in immediate reactivity to, and subsequent recovery from, laboratory-induced negative emotion. One hundred and fourteen undergraduates viewed blocks of negative pictures followed by neutral pictures. Participants’ emotional responses to negative pictures and subsequent neutral pictures were assessed via self-reported ratings. Participants’ emotional response to negative pictures was used to index level of emotional reactivity to unpleasant stimuli; emotional response to neutral pictures presented immediately after the negative pictures was used to index level of emotional recovery from pre-induced negative emotion (residual negativity). Results indicated that mindful attention was not associated with the emotional response to negative pictures, but it was associated with reduced negative emotion in response to the neutral pictures presented immediately after the negative pictures, suggesting better recovery as opposed to reduced reactivity. This effect was especially pronounced in later experimental blocks when the accumulation of negative stimuli produced greater negative emotion from which participants had to recover. The current study extends previous findings on the relationship between dispositional mindfulness and reduced negative emotion by demonstrating that mindful attention may facilitate better recovery from negative emotion, possibly through more effective disengagement from previous stimuli.     

Cultural differences in asymmetric beliefs of interpersonal knowledge in vertical and horizontal relationships

Previous studies have reported that our interpersonal knowledge shows an asymmetry; that is, we tend to believe that we know and understand other people's thoughts and feelings better than other people know and understand our own thoughts and feelings. In the present study, the authors compared American (114 men, 192 women) and Korean (99 men and 98 women) students to examine whether the asymmetry is greater in collectivistic than in individualistic culture in two types of relationships: horizontal (with best friends) and vertical (with parents). On all three items--Know, Understand, and Visibility--asymmetry was found for both horizontal and vertical relationships. Further, the Understand and Visibility items showed greater asymmetry for the Korean group than for the American group. It was concluded that asymmetry is greater in collectivistic than in individualistic culture. The cultural differences can be explained by self-consistency, sensitivity to social consequences, parent-child interaction, and living arrangement.
