Empirically distinguishing interpersonal styles within romantic relationships: What is helpful or harmful when having a goal for your romantic partner?

IntroductionRelationship research rooted in self-determination theory often focuses on autonomy support. However, rarely is this interpersonal style considered alongside other facets of relational behaviours such as directive support and control.ObjectiveThe present study aimed to distinguish the three styles by providing a tool that can simultaneously assess them.MethodA total sample of 710 French Canadians involved in a romantic relationship was used for factor extraction and test of dimensionality as well as reliability. Predictive validity was tested using multiple linear regressions with six outcomes: well-being, relationship quality, closeness, goal progress, cooperation and conflicts.ResultsResults suggested three distinct interpersonal styles, each of which showing a different pattern of prediction with the outcomes. Overall, autonomy support was associated with positive outcomes, whereas control was associated with negative outcomes. As for directive support, the global pattern was between the two others.ConclusionThe present research offers a scale which simultaneously assesses and distinguishes the autonomy-supportive, directive-supportive and controlling styles in a romantic relationship context using three items each. By examining the associations between these three interpersonal styles and various outcomes four months later, this study sheds light on helpful and harmful behaviours in relation to the goals people have for their romantic partner.     

Toward a tripartite model of intrinsic motivation

Intrinsic motivation (IM) refers to engaging in an activity for the pleasure inherent in the activity. The present article presents a tripartite model of IM consisting of IM to know (i.e., engaging in an activity to experience pleasure while learning and trying to understand something new), IM toward accomplishment (i.e., engaging in an activity for the pleasure experienced when attempting task mastery), and IM to experience stimulation (i.e., engaging in an activity for feelings of sensory pleasure). The tripartite model of IM posits that each type of IM can result from task, situational, and personality determinants and can lead to specific types of cognitive, affective, and behavioral outcomes. The purpose of this research was to test some predictions derived from this model. Across 4 studies (Study 1: N = 331; Study 2: N = 113; Study 3: N = 58; Study 4: N = 135), the 3 types of IM as well as potential determinants and consequences were assessed. Results revealed that experiencing one type of IM over the others depends in part on people's personality styles. Also, each type of IM was found to predict specific outcomes (i.e., affective states and behavioral choices). The implications of the tripartite model of IM for motivation research are discussed.     

Numerical and nonnumerical estimation in children with and without mathematical learning disabilities

There are currently multiple explanations for mathematical learning disabilities (MLD). The present study focused on those assuming that MLD are due to a basic numerical deficit affecting the ability to represent and to manipulate number magnitude ( Butterworth, 1999 , 2005 ; A. J. Wilson & Dehaene, 2007 ) and/or to access that number magnitude representation from numerical symbols ( Rousselle & No?l, 2007 ). The present study provides an original contribution to this issue by testing MLD children (carefully selected on the basis of preserved abilities in other domains) on numerical estimation tasks with contrasting symbolic (Arabic numerals) and nonsymbolic (collection of dots) numbers used as input or output. MLD children performed consistently less accurately than control children on all the estimation tasks. However, MLD children were even weaker when the task involved the mapping between symbolic and nonsymbolic numbers than when the task required a mapping between two nonsymbolic numerical formats. Moreover, in the estimation of nonsymbolic numerosities, MLD children relied more than control children on perceptual cues such as the cumulative area of the dots. Finally, the task requiring a mapping from a nonsymbolic format to a symbolic format was the best predictor of MLD. In order to explain these present results, as well as those reported in the literature, we propose that the impoverished number magnitude representation of MLD children may arise from an initial mapping deficit between number symbols and that magnitude representation.     

Finger gnosia: a predictor of numerical abilities in children?

This paper aimed to test the specificity of predicting power of finger gnosia on later numerical abilities in school-age children and to contribute to the understanding of this effect. Forty-one children were tested in the beginning of Grade 1 on finger gnosia, left–right orientation (another sign of the Gerstmann “syndrome”), and global development. Fifteen months later, numerical and reading abilities were assessed. Analyses of the results indicated that, contrary to the general measures of cognitive development, performance in the finger gnosia test was a good predictor of numerical skills 1 year later but not of reading skills, which proves the specificity of that predictor. The same conclusion was also true for the left–right orientation. However, finger gnosia could equally predict performance in numerical tasks that do or do not rely heavily on finger representation or on magnitude representation. Results are discussed in terms of the localizationist and the functional hypotheses.     

Attachment Mediates the Childhood Maltreatment–Daily Hassles Link in Low-Income,Suicidal African American Women

This study examined if attachment patterns mediated the link between childhood maltreatment and total daily and interpersonally oriented life hassles in 135 low-income, inner-city, suicidal African American women. Participants completed self-report measures of childhood maltreatment, attachment styles, and daily life hassles dimensions. Bootstrapping analyses revealed that (a) negative views of self mediated the relationship between childhood maltreatment and social and cultural difficulties and social acceptability; and (b) negative views of other mediated the relationship between childhood maltreatment and total daily life hassles, social victimization, and social and cultural difficulties. These findings can inform interventions for suicidal African American women with a history of childhood maltreatment and subsequent maladaptive attachment styles.     

On the role of harmonious and obsessive romantic passion in conflict behavior

Using the dualistic model of passion (Vallerand et al. in J Pers Soc Psychol 85:756–767, 2003), the present research examined the role of harmonious and obsessive romantic passion in individuals’ engagement in destructive behavior during conflict and in reparative behaviors following conflict with one’s partner. Results revealed that harmonious and obsessive passion were respectively negatively and positively related to engagement in destructive conflict behavior. In addition, harmonious passion was positively related to reparative behaviors following conflict while obsessive passion was not significantly related to this outcome. Importantly, these results held whether data were obtained by asking participants to recall about how things typically happen when they experience conflict with their partner (Study 1) or whether diary data were averaged across days when conflict actually happened (Study 2). Results underscore the importance of distinguishing harmonious from obsessive romantic passion.     

Regional differences in the listener's phonemic inventory affect semantic processing: A mismatch negativity (MMN) study

Using the mismatch negativity (MMN) response, we examined how Standard French and Southern French speakers access the meaning of words ending in /e/ or /ε/ vowels which are contrastive in Standard French but not in Southern French. In Standard French speakers, there was a significant difference in the amplitude of the brain response after the deviant-minus-standard subtraction between the frontocentral (FC) and right lateral (RL) recording sites for the final-/ε/ word but not the final-/e/ word. In contrast, the difference in the amplitude of the brain response between the FC and RL recording sites did not significantly vary as a function of the word’s final vowel in Southern French speakers. Our findings provide evidence that access to lexical meaning in spoken word recognition depends on the speaker’s native regional accent.
