Positive and Negative Structures and Processes Underlying Academic Performance: A Chained Mediation Model

This study proposed and tested a comprehensive, chained mediation model of university students’ academic performance. The hypothesized model included adaptive-positive and maladaptive-negative submodels. The structures and processes in the adaptive-positive submodel were hypothesized to facilitate students’ academic performance, whereas the structures and processes in the maladaptive-negative submodel were hypothesized to undermine it. A sample of 373 university students completed a set of questionnaires measuring their approaches to studying, positive and negative affect, evaluation anxiety, use of creative cognition, motivational orientations, and adaptive and maladaptive metacognitions. Participants’ end-of-semester and prior semester academic performance was retrieved from the university registry. A structural equation model explained 90 % of the variance in students’ future academic performance, supported all but one hypothesized intermediate paths, and revealed that only positive affect in studying and prior academic performance predict directly future academic performance. The theoretical and practical implications of these findings are outlined.     

Cognitive Processes Underlying Observational Learning of Motor Skills

There is evidence indicating that an individual can learn a motor skill by observing a model practising it. In the present study we wanted to determine whether observation would permit one to learn the relative timing pattern required to perform a new motor skill. Also, we wanted to determine the joint effects of observation and of physical practice on the learning of that relative timing pattern. Finally, we were interested in finding whether there was an optimal type of model, advanced or beginner, which would lead better to observational learning. Data from two experiments indicated that observation of either a beginner or an advanced model resulted in modest learning of a constrained relative timing pattern. Observation also resulted in significant parameterization learning. However, a combination of observation followed by physical practice resulted in significant learning of the constrained relative timing pattern. These results suggest that observation engages one in cognitive processes similar to those occurring during physical practice.     

Mediating and Moderating Processes in the Relation between Maltreatment and Psychopathology: Mother-Child Relationship Quality and Emotion Regulation

The present study investigated underlying processes of the effect of maltreatment on psychopathology (i.e., internalizing and externalizing problems) in a group of 111 maltreated and 110 nonmaltreated 7–10 year-old children (60% boys). We tested the moderating and/or mediating roles of emotion regulation and the mother-child relationship quality (pattern of relatedness) using Structural Equation Modeling. Emotion regulation, but not the pattern of relatedness, mediated the relation between maltreatment and psychopathology. This mediation was moderated by the pattern of relatedness: For the group of children with an insecure pattern of relatedness, maltreatment was related to lower levels of emotion regulation, which was predictive of higher levels of internalizing and externalizing symptomatology. In contrast, for the secure relatedness group, there was no mediation by emotion regulation since the impact of maltreatment on emotion regulation was not significant. Implications of the mediating role of emotion regulation and the buffering role of the mother-child relationship quality were discussed.

Psychological Processes Underlying Cultivation Effects Further Tests of Construct Accessibility

This study tested whether the accessibility of information in memory mediates the cultivation effect (i.e., the effect of television viewing on social perceptions), consistent with the availability heuristic (Tversky & Kahneman, 1973). Accessibility was operationalized as the time needed to generate frequency estimates of the real-world prevalence of crime, marital discord, and particular occupations. The independent variable was amount of soap opera viewing, and the study used only very heavy (5 or more hours per week) and very light (zero hours per week) viewers. Heavy viewers gave significantly higher frequency estimates (cultivation effect) and responded significantly faster (accessibility effect) than did light viewers, replicating the findings of Shrum and O'Gunn (1993). Soap opera viewing also had an indirect effect on the frequency estimates of crime and occupational prevalence through its effect on response latency, supporting the notion of accessibility as a mediating variable. No such mediating effect was noted for marital discord estimates.     

Diversity within Spatial Cognition: Memory Processes Underlying Place Recognition

We conducted three experiments to explore distinct memory processes involved in remembering places in spatial environments. The results of all three experiments demonstrated the viability of the process-dissociation procedure for studying spatial cognition; that procedure yielded separate measures of the role of familiarity (implicit memory) and conscious recollection (explicit memory) in recognizing scenes along a previously viewed route of travel. Those measures were not affected by whether the participants viewed videotapes or also physically walked the route of travel. Increasing the delay between encoding and retrieval led to comparable effects for familiarity and conscious recollection (Experiment 1). In contrast, the adverse consequences of dividing attention during encoding were specific to conscious recollection; familiarity estimates were unaffected (Experiments 2 and 3). Overall, the results reinforced the viability of process dissociation as a vehicle for exploring diverse memory processes underlying place recognition.     

Hope,Social Support,and Postpartum Depression: Disentangling the Mediating Effects of Negative Affectivity

We examined the potentially mediating effects of negative affectivity (NA) on the hope–depression relationship among a sample of postpartum women. We also assessed the social support reported by these women and examined the possible mediating effects of NA on the social support–postpartum depression relationship. Correlational analyses of data obtained from women (N = 98) who had given birth in the previous 6 months revealed that NA did not mediate either hope or social support in the prediction of postpartum depression. Hope accounted for a significant degree of variance in postpartum depression. These data suggest that hope has palliative effects among women following childbirth and these effects are not nullified or explained by emotional predispositions.     

Mother-Child Attachment and Gender Identity in Preadolescence

We investigated the relations of two dimensions of attachment insecurity (avoidant with mother, preoccupied with mother) to three dimensions of gender identity (gender typicality, gender contentedness, felt pressure for gender differentiation) in preadolescent children. We hypothesized that attachment insecurity (of either sort) fosters felt pressure for gender differentiation but impedes the development of felt gender typicality and gender contentedness. Participants were 863 Black, Hispanic, and White fifth graders attending public schools in the southeast United States (443 girls, 420 boys; M age = 11.1 years). Each attachment measure was associated with each gender identity measure in the expected way, but some associations hinged on child gender or ethnicity/race. Avoidant attachment was negatively associated with felt gender typicality only for White children, negatively associated with gender contentedness for the entire sample, and positively associated with felt pressure for gender differentiation only for White children. Preoccupied attachment was negatively associated with felt gender typicality for the entire sample, negatively associated with gender contentedness only for boys, and positively associated with felt pressure for gender differentiation only for girls.

Self-Controlled Practice to Achieve Neuro-Cognitive Engagement: Underlying Brain Processes to Enhance Cognitive-Motor Learning and Performance

Abstract

While self-controlled practice has been shown to be an effective practice methodology, the neuro-cognitive correlates of its effectiveness are unclear. We investigated whether learners participating in self-controlled practice exhibit increased neuro-cognitive engagement compared to externally controlled practice. Two groups (self-controlled and yoked) of 16 participants practiced and performed a golf putting task over 3 days. Working memory engagement, central executive activity, and cortical activation were assessed via electroencephalography as indicators of neuro-cognitive engagement. The self-controlled group exhibited more consistent working memory engagement, and greater central executive activity, compared to the yoked group during practice. Relationships were also observed between neuro-cognitive engagement during self-controlled practice and performance improvement, indicating that self-controlled practice uniquely benefitted from increased neuro-cognitive engagement.     

不同性质汉语否定句心理加工过程的实验研究

采用词汇/图片判断范式,以不同性质的否定句和其对应的肯定句为实验材料,以词汇/图片判断的反应时和正确率为因变量指标,探讨不同性质汉语否定句的加工是否是动态变化的过程。研究分为两个大实验四个小实验。实验一采用句图匹配任务,否定句是对具体现实情境的否定,实验1a和1b分别考察句图短时间间隔和长时间间隔下否定意义的加工。实验二采用词汇判断任务,实验材料为隐喻形式的否定句。实验2a和2b分别为句词短时间间隔和长时间间隔。实验1发现短时间间隔时,句图不匹配条件下图片判断时间短于匹配时;长时间间隔时相反,句图匹配条件下图片判断时间更短。实验2发现短时间间隔时,句词不匹配条件下词汇判断时间短于匹配时,而长时间间隔时匹配与否的词汇判断时间无差异。综合两个实验结果表明,对现实情境的具体否定句符合两阶段模拟加工,被否定意义在加工早期被表征,但会因句子实际意义的通达而得到抑制;而隐喻形式的抽象否定句加工更符合抑制/保存假说,被否定意义在加工早期被表征,并在加工后期仍保留在头脑中。     

Consumerism and Well-Being in India and the UK: Identity Projection and Emotion Regulation as Underlying Psychological Processes

A growing body of evidence shows that a materialistic value orientation is linked to lower well-being (Dittmar 2008; Kasser & Kanner, 2004), but we know little about factors that influence this association, or linked behavioural tendencies, particularly in developing countries, such as India. Extending our previous research (Dittmar 2005a, b; Dittmar et al. 2007), we develop a model in which endorsement of materialistic values is linked to buying motives focused on identity projection and emotion regulation, which, in turn, are linked to lower well-being and dysfunctional consumer behaviour. We tested these hypothesised associations in surveys with 236 younger and older adults in India and the UK, and found that they were consistent with our model, showing few country or generational differences. Theoretical and applied implications are discussed, as well as directions for future research.     

Dissociation of Processes Underlying Spatial S-R Compatibility: Evidence for the Independent Influence of What and Where

The process-dissociation procedure was used to estimate the influence of spatial and form-based processing in the Simon task. Subjects made manual (left/right) responses to the direction of arrows (> or <) presented to the left or right of fixation. Manipulating the proportion of incongruent trails (e.g., a right-pointing arrow presented to the left of fixation) affected both the size and direction of the Simon effect. To account for this pattern of data, we compared process estimates based on three possible relationships between spatial and form-based processing: independence, redundancy, and exclusivity. The independence model provided the best account of the data. Most telling was that independent form-based estimates were superior at predicting observed performance on arrows presented at fixation and did so consistently across conditions (r′s > .80). The results provide evidence that the form ("what") and spatial location ("where") of a single stimulus can have functionally independent effects on performance. They also indicate the existence of two kinds of automaticity—an associative ("implicit learning") component that reflects prior S-R mappings and a nonassociative component that reflects the correspondence between stimulus and response codes.     

Mother-Child and Father-Child Interactional Synchrony in Dyadic and Triadic Interactions

Patterns of interactional synchrony were compared in mother-child and father-child dyads during dyadic and triadic interactions. Forty-two dual-earner families from the French province of Québec, Canada, participated in the study with their 32 months-old child. Parent?Cchild interactions were coded using a taxonomy including the social partners?? physical proximity, visual and body orientation, and dyadic involvement. Analyses show similar patterns of interactional synchrony in mother-child and father-child dyads in the dyadic context while father-child dyads presented less interactional synchrony than mother-child dyads when interacting in triad. Discussion focuses on the impact of the context and on the factors that could explain the changes in father-child patterns of interaction from one context to another.

Disentangling behavioral intention and behavioral expectation

Social psychologists have extensively researched behavioral intention and its relation to future behavior, usually within the framework of M. Fishbein and I. Ajzen's (1975, Belief, attitude, intention and behavior: An introduction to theory and research, Reading, MA: Addison-Wesley) theory of reasoned action. However, the field has confounded two separate constructs while investigating intention: behavioral intention (BI) and what P. R. Warshaw, B. H. Sheppard, and J. Hartwick (in press, in R. Bagozzi (Ed.), Advances in marketing communication, Greenwich, CT: JAI Press) have coined behavioral expectation (BE), which is the individual's self-prediction of his or her future behavior. In this paper we define both constructs and explain how they differ in terms of the processes by which they are formed, their roles in determining behavior, and their utilities as behavioral predictors. We propose that behavioral expectation is the more accurate overall predictor since many common behaviors are unreasoned (i.e., mindless or habitual) behaviors, goal-type actions, or behaviors where the individual expects his or her intention to change in a foresseable manner. These are all cases where present intention (BI) is not the direct determinant of behavior but where the individual may be capable of appraising whatever additional determinants exist and of including them within his or her behavioral expectation. A study (N = 197) is reported in which student subjects received either a BE (n = 113) or a BI (n = 84) version of a questionnaire pertaining to their performance of 18 common behaviors. Overall, behavioral expectation was the better predictor of self-reported performance.     

Mother-Child Conversation Styles and Children's Laboratory Memory for Narrative and Nonnarrative Materials

The study reported here was designed to examine influences of mothers' early conversational styles on children's episodic memory for events experienced outside of the mother-child relationship. Fifty-three 3-, 4-, 5-, and 6-year-old children participated in picture-book interaction tasks with their mothers and with an unfamiliar investigator. Conversational messages were coded for their narrative and paradigmatic content. The children were also administered cued- and free-recall laboratory tasks for object names, object locations, animal facts, and story narratives. Reliable correlations were found between mothers' and children's levels of narrative talk in the mother-child picture-book task and between children's levels of narrative talk with mother and with an unfamiliar investigator. Recall analyses showed that the younger children's levels of narrative talk during picture-book tasks with mothers were positively related to the children's laboratory recall for story materials, unrelated to laboratory recall of object names and animal facts, and negatively related to laboratory recall for the spatial locations of objects. Connections between conversation styles and recall proficiency were less apparent and not reliable for the 5- and 6-year-old children in the sample. Differences between these age effects and those found in research on children's autobiographical memory are discussed.     

Disentangling posterror and postconflict reduction of interference

Conflict monitoring theory (CMT; Botvinick, Braver, Barch, Carter, & Cohen Psychological Review, 108, 624–652, 2001) states that response conflict, the simultaneous activation of two competing responses, increases task focus and reduces interference from irrelevant information. CMT also defines errors as conflict, and reduced interference effects have consistently been reported following errors (Ridderinkhof Psychological Research, 66, 312–323, 2002). However, previous computations of this posterror reduction of interference (PERI) have overlooked the congruency of the previous trial. This is problematic, because most errors are made on incongruent trials, creating a confound between (previous) accuracy and (previous) congruency. Therefore, it is likely that reduced interference following errors is in fact the congruency sequence effect (i.e., reduced interference following incongruent, relative to congruent, trials). Our results corroborate this idea by demonstrating that participants indeed showed significant PERI following a congruent trial, but inverse PERI following an incongruent trial. These findings are discussed in light of the adaptation-by-binding account (Verguts & Notebaert Psychological Review, 115, 518–525, 2008, Trends in Cognitive Sciences, 13, 252–257, 2009).     

The Underlying Role of Negative Affect in the Association between PTSD,Major Depressive Disorder,and Generalized Anxiety Disorder

Clinicians and researchers have found differential diagnosis to be difficult, particularly for conceptually similar disorders. One category of particular interest has been distress or internalizing disorders, theorized to be related via an underlying construct of generalized distress or negative affect. The present study attempted to address the comorbidity of three distress disorders - posttraumatic stress disorder (PTSD), major depressive disorder (MDD), and generalized anxiety disorder (GAD) - using latent analyses by controlling for the variance attributable to negative affect. The sample consisted of 265 trauma-exposed individuals who completed self-report measures of PTSD, MDD, GAD, and negative affect. Confirmatory factor analysis was used to test initial model fit. Next, the model was re-computed, controlling for negative affect by regressing negative affectivity at the item-level. Results indicated that a significant amount of variance within and between these diagnostic categories is attributable to negative affect at both the item- and factor-level. The hypothesis that MDD’s non-somatic/affective factor and the GAD factor would have the highest attenuations in factor loadings after controlling for negative affect was supported. Therefore, negative affect significantly influences the co-occurrence of PTSD, MDD, and GAD clinically, emphasizing the need for transdiagnostic interventions for trauma victims.     

A Mother-Child, Multiple-Family, Counseling Program: Procedures and Results

The purpose of this study was to determine the effects of a family counseling program on the following variables: (a) parents' family satisfaction, perceived integration, and family congruence; (b) the number of positive and negative responses communicated among family members; and (c) an undesirable behavior exhibited by one child in the family. The sample consisted of 14 families in the experimental condition and 11 families in the control condition.
Mother and one child had responsibility for teaching other family members the principles taught during the multiple-family category sessions.
The findings indicated: (a) parents receiving family counseling increased significantly their family-satisfaction and perceived-integration scores as compared to the parents not receiving counseling; (b) families receiving counseling increased significantly the number of positive responses among them compared with the control families; (c) children receiving counseling decreased significantly the frequency of exhibiting a specific undesirable behavior; and (d) no significant differences were found between the groups of families in parents' family-congruence scores and in the number of negative responses communicated among family members.
