- Groove-based rhythm is a basic and much appreciated feature of Western popular music. It is commonly associated with dance, movement and pleasure and is characterized by the repetition of a basic rhythmic pattern. At various points in the musical course, drum breaks occur, representing a change compared to the repeated pattern of the groove. In the present experiment, we investigated the brain response to such drum breaks in a repetitive groove. Participants were scanned with functional magnetic resonance imaging (fMRI) while listening to a previously unheard naturalistic groove with drum breaks at uneven intervals. The rhythmic pattern and the timing of its different parts as performed were the only aspects that changed from the repetitive sections to the breaks. Differences in blood oxygen level-dependent activation were analyzed. In contrast to the repetitive parts, the drum breaks activated the left cerebellum, the right inferior frontal gyrus (RIFG), and the superior temporal gyri (STG) bilaterally. A tapping test using the same stimulus showed an increase in the standard deviation of inter-tap-intervals in the breaks versus the repetitive parts, indicating extra challenges for auditory-motor integration in the drum breaks. Both the RIFG and STG have been associated with structural irregularity and increase in musical-syntactical complexity in several earlier studies, whereas the left cerebellum is known to play a part in timing. Together these areas may be recruited in the breaks due to a prediction error process whereby the internal model is being updated. This concurs with previous research suggesting a network for predictive feed-forward control that comprises the cerebellum and the cortical areas that were activated in the breaks.

- The aim of this study was to examine closer the conflicting results from previous studies concerning the relation- ship between Facebook use and self-esteem using the Facebook Intensity Scale and Rosenberg’s Self-Esteem Scale (N = 107). In line with some previous studies, our data confirmed that there is a relationship between Facebook usage and self-esteem, but the applied scales allowed a more refined assessment of it. The results showed, after controlling for demographic variables, that participants with low Facebook intensity reported on average higher self-esteem than those who did not use Facebook or those with high Facebook intensity, while those with medium Facebook intensity had significantly higher self-esteem compared to the participants with high Facebook intensity. Future studies should address the underlying causal relations using a time-bound observation method.

Disordered eating in a general population : just another depressive symptom or a specific problem?
- 2014
-
Konferensbidrag (refereegranskat)abstract
- Previous research has shown that about 30% of adolescent girls and 15% of adolescent boys suffer from disordered eating (DE) which can be defined as problematic eating below criteria for eating disorders according to DSM-V (Hautala et al., 2008; Herpertz-Dahlman et al., 2008). Even sub-clinical unhealthy weight-control behaviors have predicted outcomes related to obesity and eating disorders five years later (Neumark-Sztainer et al., 2006). However, two issues question the validity of DE. First, in contrast to eating disorders, under- or overweight/obesity are not necessary parts of DE. Second, some symptoms and correlates of DE are similar to those of depression. E.g., parent-adolescent relationships seem to play an important role in explaining both DE (Hautala et al., 2011; Berge et al., 2010) and internalizing problems (Soenens et al., 2012). Thus, this study examined associations between DE and a wide range of internalizing and externalizing problems, parent-adolescent relationship characteristics, and food intake and sleep habits in a general population of adolescents. Comparing results with and without controlling for depression reveals whether DE is a specific problem or merely a depressive symptom. This study also explored whether DE and the other variables under study are associated independently of weight status (underweight, overweight/obesity, and normal weight), specific to under- or overweight, or spurious if taking weight status into account.The study is based on the first wave of an on-going longitudinal study, and all measures are child-reported (N=1,281). Adolescents attending grades 7 to 10 in a Southern Swedish municipality (age 12.5 to 19.3, M = 15.2, SD = 1.2) filled out questionnaires in class. DE was measured using the SCOFF, a five-item screening scale validated for use in general populations (e.g. Muro-Sans et al., 2008; Noma et al., 2006).The results of univariate ANOVAs indicate that associations with DE were largely independent of weight status. Moreover, most associations with disordered eating were spurious when controlling for depression. However, some associations remained. Above and beyond depression effects, adolescents with DE reported lower self-esteem, stronger feelings of being over-controlled by their parents and active withholding of information towards them, consumption of fewer meals during the week, and higher levels of daytime sleepiness. Boys with ED slept more hours during the week and ate more fruits and vegetables than boys without ED. In conclusion, despite an overlap between depressive symptoms and disordered eating, this study provides ample evidence that sleep, nutrition habits, self-esteem, and parental control issues distinguish eating disordered adolescents from those suffering from general depressive symptoms.

-
Ingår i: Restorative Neurology and Neuroscience. - 1878-3627. ; 32:1, s. 141-147
-
Tidskriftsartikel (refereegranskat)abstract
- In this paper the concept of incentive motivational salience is briefly described, pioneering studies on the subject of the mesolimbic motivational system are reviewed, and studies we have been involved in conducting which elaborate on this subject are discussed. In particular, we aim to show that the mesolimbic motivational system is recruited as a reaction to primary and secondary reinforcers as a function of salience, that is independent of valence. Furthermore, studies showing that both psychological and pharmacological interventions can affect the function of the mesolimbic motivational system and how its' dysfunction is related to psychopathological phenomena with an emphasis on psychosis are discussed.

Test learning as an explanation of dual task dissociations in implicit learning
- 2014
-
Konferensbidrag (refereegranskat)abstract
- Artificial grammar learning (AGL) has been used extensively to study implicit learning. In this task participants first observe letter sequences generated by a grammar. In a later test phase participants are asked to distinguish new grammatical and ungrammatical sequences. Participants are able to do this, both when the letters instantiating the grammar remain the same (standard AGL) and when the letters are changed between training and test (transfer AGL). Virtually all models of AGL assume that there is no learning during the test phase. Yet, test learning can occur in AGL and the structural constraints of a grammar can imply useful cues at test as well as at training. For example, grammatical test sequences are often more similar to each other than are ungrammatical test sequences to each other. Similarity to test sequences observed so far can then be used as a cue for classification. In the current research I used an episodic memory model, Minerva II, in order to simulate a recent study by Hendricks et al. (2013). They found that for standard AGL performing dual tasks at test was more detrimental to performance than dual tasks at training. For transfer AGL performing dual tasks at training reduced performance as much as dual tasks at test. The authors interpreted these results as revealing automatic vs. intentional process in AGL: transfer AGL requires intentional processes at both training and test, whereas standard AGL requires intentional processes at test but only automatic processes at training. I modelled these experiments using a version of Minerva II extended to learn at test. The model encodes sequences probabilistically into memory based on a learning rate at both training and test. Each test sequence is classified based on the similarity to sequences encoded in memory so far, so that test sequences also influence classification. The model does not distinguish between automatic and intentional processes. The learning rate at training was varied independently of the learning rate at test in order to simulate dual task manipulations in different phases of the task. In order to model transfer AGL I used a simple repetition coding scheme in Minerva II. For standard AGL the simulations revealed that learning rate at test had a much greater impact on classification than learning rate at training in Minerva II. In contrast, for transfer AGL the effects of changing learning rates at training was the same as changing learning rate during test. In essence, the empirical data may not reveal automatic vs. intentional processes, but simply effects of a single similarity process. The simulation results and the notion of test learning invites useful avenues for further computational and empirical research in order to establish the processes involved in implicit learning.

Do parents only have to avoid being nasty, or should they even be nice? : the case of adolescent substance use and deviance
- 2012
-
Konferensbidrag (refereegranskat)abstract
- Traditionally, parents’ firm and consistent behavior control has been regarded as effective protection against adolescents’ drug use and delinquency (Steinberg, 2001). However, the validity of findings has been questioned (Stattin & Kerr, 2000; Kerr & Stattin, 2000). The widely-used indicator of behavior control, parental knowledge, appears rather to reflect a trusting relationship (Masche, 2010). However, little is known about which facets of the relationship are most important: Is it more “nasty,” guilt inducing and interfering behavior, i.e. psychological control, which leads to substance use and deviance? Or is it parents’ ability to be “nice” and create close family relations marked by solidarity that prevents these problem behaviors?A total of 143 adolescents attending grade 9 (age 15-16, 58% male) in two medium-sized Swedish cities filled out questionnaires at school. Scales on alcohol and drug use focused on frequency and intensity of use and on symptoms of substance abuse. The deviance scale ranged from minor delinquency to violent acts. Adolescents answered also scales on their experienced relationship quality to their parents, on parents’ psychological control and behavior control (e.g., needing permission before going out on the evening). Mother and father scales were summed because of their high inter-correlations. Drug consumption was generally low, and several items did not even vary between participants. Still, all scales were sufficiently reliable (α’s ≥ .80). Because 44% of the sample had other than Swedish ethnic background – in most instances were the parents born in the Middle East –, ethnicity, gender, and their interaction were included into the analyses, but did not predict substance use or deviance.Although alcohol use and deviance were highly correlated, these two problem behaviors were somewhat differently associated with parenting and relationship variables: Adolescents who consumed a lot of alcohol tended to have poor relationships to psychologically controlling parents. However, deviant adolescents reported in the first place psychologically controlling parents and only to a lesser degree also a poor relationship quality. Drug use (which generally was low) was only associated with psychological control. Multiple regression analyses revealed whether each parenting and relationship variable uniquely predicted substance use and deviance. The results were similar to the bivariate correlations, confirming the general importance of psychological control. Relationship quality still predicted low alcohol use, but was not any longer important for deviance when controlled for psychological control. Behavior control did not predict any of these problem behaviors in any analysis.This study confirms findings questioning the role of behavior control (Kerr & Stattin, 2000; Stattin & Kerr, 2000). It tells what might be important instead. Hostile, guilt-inducing behavior was consistently associated with externalizing problems whereas a close relationship showed more specific associations. To the degree that parents affect adolescents’ externalizing behaviors rather than are affected by them, these findings suggest that parents above all should avoid being “nasty,” i.e. psychologically controlling. Being “nice,” i.e., to contribute to a close companionship with their children, also appears important, but more specifically against alcohol consumption.

Five years later : effects of parenting styles and parent-adolescent relationships on young adults’ well-being
- 2011
-
Konferensbidrag (refereegranskat)abstract
- Parents can support their adolescent child’s psychosocial development by a parenting style which is warm and involved, firm and consistent, and which grants psychological autonomy (the freedom to have one’s own thoughts and feelings). Psychological autonomy granting is regarded as particularly beneficial for the prevention of anxiety, depression, or other kinds of internalizing distress (McLeod, et al., 2007; Steinberg, 2001). However, longitudinal research has produced mixed evidence (Birmaher, et al., 2000; Colarossi & Eccles, 2003; Galambos et al., 2003; Steinberg, et al., 1994). Even less is known on long-term effects into young adulthood. Besides parental behaviors, also the parent-adolescent relationship might be important. Teens who feel close to their parents and who communicate frequently with them might experience a “secure base” which protects against depression and fosters the children’s well-being even in the future. Thus, this study examined reciprocal effects between parenting styles (psychological control and affection) and the parent-adolescent relationship (felt closeness to and communication with parents) and emotional, social and psychological well-being, and depression.This study used the 2002, 2005, and 2007 waves of an ongoing longitudinal study, representative for the USA. Out of 1,319 adolescents aged 11-19 in 2002, 575 young adults, then 18-22 years old were re-interviewed in 2005. By 2007, more adolescents had reached young adulthood, thus, 878 young adults of age 18-24 were re-interviewed in 2007. Also 224 of the originally youngest adolescents were re-interviewed in 2007 as a separate sample. Parenting styles were assessed in the adolescent data collections 2002 and 2007, and parent-child relationships and well-being at all occasions.Albeit adolescents’ perceptions of mothers’ and fathers’ parenting styles were highly correlated, specific effects on well-being occurred in cross-lagged regression analyses. Maternal psychological control in 2002 predicted lowered levels of emotional and social well-being and elevated levels of depression in 2005 (β’s = -.10, -.08, and .11, resp.). In part, these effects were found even after five years in 2007. Maternal support did not have any significant effects. For fathers, only one effect was found, of psychological control 2002 on depressive symptoms 2007 (β = .08). Measures of the parent-adolescent relationship did not predict well-being, with the exception of communication to mothers in 2002 which predicted emotional well-being in 2005.In the opposite direction of effects, depression predicted maternal psychological control five years later (β = .18, p = .023), despite the smaller sample of still adolescent respondents. Also some effects of parenting and of well-being on the parent-young adult relationship occurred.In conclusion, advice to parents might focus on how to avoid psychologically controlling behaviors, especially for mothers were these might conflict most with North-American gender roles. Future research should investigate why such detrimental behaviors occur in response to adolescents’ emotional problems. That parental support as a general style proved unimportant does not mean that support never would be needed: It might be that in key situations of danger or adolescent problems, adolescents need the impression that parents care, and not only abstain from psychological control (Olsson & Wik, 2009).

How to foster depression : bother your adolescent child all the time, but leave it alone when it needs you
- 2010
-
Konferensbidrag (refereegranskat)abstract
- Is there another way to predict adolescents’ depressive symptoms than by trait-like parenting characteristics, such as affective support (Barber, Stolz, & Olsen, 2005)? Drawing from a systems perspective (Lollis & Kuczynski, 1997) and Social Domain Theory (Smetana & Asquith, 1994), this paper suggests that parental responses in key situations might be important for the development of adolescent depression: (a) adolescent-parent conflict; (b) dangerous situations; (c) need of help with a problem. These three situations require steering adolescents’ behaviors in a responsive way, i.e., combinations of demandingness and responsiveness. Thus, the roles of authoritative, authoritarian, indulgent, and indifferent parental responses in these key situations will be rested.In order to have a standard of comparison, well-established parenting styles (Barber, et al., 2005; Steinberg, 2001) will be evaluated, too. Lack of support has been found to predict depressive symptoms. The prediction by behavior control and the support-by-control interaction will be tested as well, for a better comparability to the test of parental responses in specific situations.A total of 108 Swedish adolescents aged 14-15 (67 girls, 41 boys) filled out questionnaires at school. For depressive symptoms and parental support, well-established American scales were used. Behavior control was measured by scales tapping parental control and solicitation of information, respectively. 3 (situations) by 4 (parental responses) by 2 (parent genders) scales of parental responses in key situations were newly developed. For each type of situations, the respondents received two typical examples (e.g., having problems with a friend or a girlfriend/boyfriend as an example of a problem) and rated the frequencies of various parental responses. Because all mother and father scales were highly correlated, they were standardized and added (complementary analyses with either mother or father data yielded similar results; so did analyses including adolescent gender).Parental responses in key situations explained 30% of variance of adolescent depression. Authoritative responses to problems were associated with low levels of depression. Moreover, indifferent responses to all three kinds of situations predicted higher levels of depression.Main effects of parenting style variables explained 14% of the variance of depression. Adding the interactions between support and parental control and solicitation explained additional 8% of variance. Most of this effect was due to an interaction between acceptance and solicitation. Authoritarian parenting predicted the highest depression levels whereas supportive styles predicted low depression. When entering either reactions in key situation first into the regression equation and parenting styles next, or vice versa, each of them predicted significant portions of variance above and beyond the other. However, reactions in key situations produced the larger increase in explained variance.Albeit cross-sectional data do not allow for causal conclusions, this study has generated important hypotheses for future studies: If parents constantly bother their adolescent child with requests to talk about something, in combination with low levels of support, the child is likely to show elevated levels of depression. Even more deleterious might be adolescents’ experience to be left alone when they need their parents.

It takes two to tango : teen internalizing and externalizing problems are predicted by the interaction of parent and teen behaviors
- 2014
-
Konferensbidrag (refereegranskat)abstract
- Associations between parenting behaviors of support, behavior control and overcontrol, and psychological control/disrespect with adolescent internalizing and externalizing problems have been studied extensively (Barber et al., 2012; Kerr & Stattin, 2000), and also adolescent behaviors of disclosure and secrecy in the context of these problems (Frijns et al., 2010). However, few studies have assessed how parent and child behaviors might moderate each other’s associations with problems (Keijsers et al., 2009). This study investigates interaction effects of the above-mentioned parent and adolescent behaviors when predicting depression, loneliness, and low self-esteem (internalizing), and delinquency, aggression, and drug/alcohol use (externalizing). Given the variety of behaviors and problems under study, it is hypothesized that various kinds of moderation effects will emerge.An ethnically diverse sample of 1,281 adolescents attending grades 7 to 10 in a Southern Swedish municipality (age 12.5 to 19.3, M = 15.2, SD = 1.2) filled out questionnaires in class. All scales have been published internationally; however, some items were added to short scales. Each of the internalizing and externalizing problems was regressed on all possible combinations of one of the four parenting variables and one of the two adolescent behaviors under study, resulting in 48 regression analyses.Confirming previous findings, parent psychological control and overcontrol were associated with internalizing and externalizing problems, and behavior control and insufficient support with internalizing problems. Adolescent disclosure predicted low levels of both kinds of problems and secrecy predicted high levels. Two-way interactions of parent and adolescent behaviors added significantly (p < .05) to the variance in 13 of 48 analyses which is beyond chance level (p < .001). In addition to the inspection of significant effects, t-values across all analyses were analyzed in order to distinguish between more general trends and solitary effects on specific internalizing or externalizing problems only. Confirming the hypothesis, interaction effects varied across the combinations of parent and adolescent behaviors (η2 = .26) and were further moderated by the distinction between internalizing and externalizing problems (η2 = .38). These effects were grouped into five kinds of interaction effects: In mutually enhancing and mutually exacerbating effects, two positive or two negative, respectively, behaviors increased each other’s associations with problem levels. In protection effects, usually adolescents’ behavior reduced associations between negative parenting and problems. Relationship split effects might reflect an alienated parent-adolescent relationship in which negative behaviors cannot do much additional harm. Finally, maintained relationship/sabotage means that the lowest level of problems occurred if one generation maintained the relationship by a positive behavior and the other generation abstained from “sabotaging” it by a negative behavior. Otherwise, problem behaviors increased sharply without the other generation’s behavior having any large effect any longer.In conclusion, analyses provide ample evidence that adolescents’ behavior moderates links between parents’ behaviors and adolescents’ internalizing and externalizing problems. Possible causal interpretations include adolescents as “gatekeepers” of parenting efforts, families’ functional and dysfunctional adaptations, and parent and child behavior combinations as consequences of internalizing and externalizing problems.

You Can Check Out any Time You Like, But You Can Never Leave : Psychological Control of Teens Predicts Young Adults’ Depression
- 2011
-
Konferensbidrag (refereegranskat)abstract
- Parental support predicts low levels of depression in teenagers, and psychological control high levels. However, this pattern holds true for cross-sectional research only whereas longitudinal support is mixed at best. Moreover, few studies have investigated long-term effects into young adulthood. This study explores effects of teenagers’ experienced parental support and psychological control on depression and parent-child relationships in young adulthood, three and five years later. It also explores parental behaviors as outcomes of teen depression. Out of 1,319 U.S. American adolescents aged 11-19 in 2002, those who had reached young adulthood by 2005 (n = 575) and 2007 (n = 878), respectively, were re-interviewed. Also the youngest participants, who still were in adolescence, took part in 2007 (n = 224). In cross-lagged panel regressions, maternal psychological control predicted depression and low well-being over time whereas maternal support predicted close parent-child relationships. For the youngest participants, effects on parenting were tested, and depression predicted increased maternal psychological control after five years. Only few effects were found for fathers. These findings suggest that psychological control does not make young adults withdraw from the relationship, despite their increased independence. Instead, they still expose themselves to this parenting behavior, resulting in increased depression. Depression also contributes to psychological control, resulting in a vicious circle of maternal psychological control and youth depression. Parental support in contrast is linked to relationship closeness over time, but largely unrelated to both depression and psychological control. The differential roles of psychological control and support will be discussed further.
