Analogous selection processes in declarative and procedural working memory: N-2 list-repetition and task-repetition costs

Working memory (WM) holds and manipulates representations for ongoing cognition. Oberauer (Psychology of Learning and Motivation, 51, 45–100, 2009) distinguishes between two analogous WM sub-systems: a declarative WM which handles the objects of thought, and a procedural WM which handles the representations of (cognitive) actions. Here, we assessed whether analogous effects are observed when participants switch between memory sets (declarative representations) and when they switch between task sets (procedural representations). One mechanism assumed to facilitate switching in procedural WM is the inhibition of previously used, but currently irrelevant task sets, as indexed by n-2 task-repetition costs (Mayr & Keele, Journal of Experimental Psychology: General, 129(1), 4–26, 2000). In this study we tested for an analogous effect in declarative WM. We assessed the evidence for n-2 list-repetition costs across eight experiments in which participants switched between memory lists to perform speeded classifications, mental arithmetic, or a local recognition test. N-2 list-repetition costs were obtained consistently in conditions assumed to increase interference between memory lists, and when lists formed chunks in long-term memory. Further analyses across experiments revealed a substantial contribution of episodic memory to n-2 list-repetition costs, thereby questioning the interpretation of n-2 repetition costs as reflecting inhibition. We reanalyzed the data of eight task-switching experiments, and observed that episodic memory also contributes to n-2 task-repetition costs. Taken together, these results show analogous processing principles in declarative and procedural WM, and question the relevance of inhibitory processes for efficient switching between mental sets.     

Changing Values: Attitudes about Intimate Partner Violence in Immigrants and Natives in Five Western Countries

This article explores attitudes about Intimate Partner Violence Against Women (IPVAW) amongt immigrant (first and second generation) and native populations in five post-industrial societies (Germany, Netherlands, New Zealand, Sweden, and USA). Using the sixth wave of World Values Survey, we conclude that there are significant differences, after controlling for demographic factors, between all three sub-populations in attitudes about IPVAW, with first generation immigrants more supportive of IPVAW than either natives or second generation immigrants. We also show that, for the three sub-populations, interactions of attitudes regarding interpersonal violence, gender equality and sexual tolerance are good predictors of attitudes about IPVAW.     

Effects of Social Norms Information and Self-Affirmation on Sugar-Sweetened Beverage Consumption Intentions and Behaviors

The separate and combined efficacy of a social norms and a self-affirmation intervention to motivate decreased sugar-sweetened beverage (SSB) consumption was examined in 2 experiments. College students were randomly assigned to receive information about SSB consumption risks, norms, both, or neither. In addition, participants performed either a self-affirmation or control task. Self-affirmation only weakly affected SSB consumption intentions and behaviors. However, participants in Experiment 2 who received risks information, norms information, or both reported greater SSB reduction intentions than did those who received no information. Two weeks later, those who received both types of information reported more frequent behavior change preparations, and it appears this effect may have been partially mediated by the changes in intentions to reduce SSB consumption.     

Investigating the effectiveness of brief cognitive reappraisal training to reduce fear in adolescents

As adolescent anxiety is common and costly, identifying effective strategies to reduce symptoms is a priority. This study tested whether adolescents could learn to use cognitive reappraisal strategies to attenuate fear during extinction learning. Fifty-seven participants (12–15 years) viewed images of two neutral faces, one which was paired with a fearful expression and shrieking scream (conditioned threat stimulus) and the other that was never paired with the aversive outcome (conditioned safety stimulus) during fear acquisition. Before extinction, participants either received cognitive appraisal training, which explored alternative, benign meanings associated with the scream or a control activity. Self-reported fear ratings in the cognitive reappraisal group were significantly lower to both the conditioned threat and safety stimuli after extinction than the control group. These findings did not characterise fear-potentiated startle data. Potential reasons for the lack of consistency between measures are considered.     

The Dark Side of Heterosexual Romance: Endorsement of Romantic Beliefs Relates to Intimate Partner Violence

Romance and control are often conflated by the media, and individuals may believe that certain controlling or jealous behaviors by men toward women are romantic and can be a sign of love and commitment in heterosexual relationships. The current study explored three types of romantic beliefs among women: endorsement of the ideology of romanticism, highly valuing romantic relationships, and the belief that jealousy is good. The goal was to determine whether these beliefs would be related to finding controlling behaviors romantic as well as to reported experiences of both physical and psychological intimate partner violence (IPV). We surveyed 275 heterosexual-identified women, aged 18 to 50, and measured their endorsement of romantic beliefs, the extent to which they romanticized controlling behavior, and experiences of physical and psychological abuse within their current or most recent romantic relationship. Romantic beliefs were related to romanticizing controlling behaviors, which, in turn, was related to experiences of IPV. There was also a significant indirect relationship between romantic beliefs and experiences of IPV. The data indicate that seemingly positive romantic ideologies can have insidious negative effects. Findings may be useful for clinicians and those who advocate for prevention of IPV as they illustrate a need to refocus traditional ideas of healthy relationships at the societal level.     

Sensory processing sensitivity and its relation to parental bonding, anxiety, and depression

Sensory processing sensitivity is a recently proposed construct referring to a tendency to process a variety of information more strongly and deeply than others. Although some research has found links between sensory processing sensitivity and psychological difficulties, highly sensitive people may not necessarily be predisposed to negative affect, but may be more sensitive to poor parenting. Two hundred thirteen college students were given a measure of sensory processing sensitivity (the HSPS), the parental bonding scale (measuring parental care and over-protection), the trait anxiety scale, and the Beck depression inventory. Sensory processing sensitivity predicted both anxiety and depression above and beyond parental factors, indicating that it may be an independent risk factor. An interaction was found between sensory processing sensitivity and parental care when measuring depression. Highly sensitive people may be particularly sensitive to uncaring parents. Results indicate that sensory processing sensitivity may be a temperamental disposition that interacts meaningfully with environmental factors.     

A Dynamic, Multi-Level Model of Culture: From the Micro Level of the Individual to the Macro Level of a Global Culture

Cet article propose un modèle de la culture à plusieurs niveaux, composé de caractéristiques dynamiques et structurelles qui rendent compte de l’interaction entre les différents niveaux de culture. On commence par présenter un résumé des modèles existants de la culture, puis on poursuit en proposant le modèle de la culture à plusieurs nivaeux. La dimension structurelle représente la construction emboîtée de la culture depuis le niveau le plus extensif d’une culture globale jusqu’à la représentation de la culture au niveau individuel en passant par les cultures nationale, organisationnelle et de groupe. La nature dynamique de la culture évoque les processus descendants et ascendants quand l’un des niveaux culturels entraîne des changements à d’autres niveaux. Plus particulièrement, le modèle soutient que le niveau le plus global de la culture affecte, par l’internédiaire de processus descendants, les changements comportementaux des gens relevant de différentes cultures. Inversement, des changements comportementaux au niveau individuel deviennent, grâce aux processus ascendants, des valeurs et des normes comportementales partagées, modifiant la macroculture. L’article demande que l’om passe de la culture conçue comme une entité stable à la culture perçue comme étant une entité dynamique, et que l’on accorde davantage d’intérêt aux interactions entre les différents niveaux de culture. This paper proposes a multi‐level model of culture, consisting of structural and dynamic characteristics that explain the interplay between various levels of culture. The paper begins with a summary of existing models of culture and continues with the proposed multi‐level model of culture. The structural dimension represents the nested structure of culture from the most macro level of a global culture, through national, organisational and team cultures, and down to the representation of culture at the individual level. The dynamic nature of culture conveys the top‐down–bottom‐up processes where one cultural level affects changes in other levels of culture. Specifically, the model proposes that globalisation, as the macro level of culture, affects, through top‐down processes, behavioral changes of members in various cultures. Reciprocally, behavioral changes at the individual level, through bottom‐up processes, become shared behavioral norms and values, modifying the culture of a macro level entity. The paper calls for a shift in the research focus on culture as stable, to culture as a dynamic entity and for a greater focus on the interplay between different levels of culture.     

Predictors and Correlates of Collective Action

Social identity theory suggests that feminist identity should predict engagement in collective action on behalf of women. We examined predictors of collective action by asking female college students (N = 215) to complete a set of questionnaires that measure life experiences, beliefs about feminism and collective action, feminist self-labeling, and involvement in women-focused collective activities. Life experiences (i.e., having a feminist mother, having taken a women's studies class, and having experienced sex discrimination), feminist attitudes and beliefs, feminist self-labeling, and belief in collective action were positively correlated with collective action, whereas conservatism was negatively correlated with collective action. A logistic stepwise regression revealed that the Synthesis stage of feminist identity development was the only variable that uniquely contributed to predicting feminist activism.     

Dream rebound of suppressed emotional thoughts: the influence of cognitive load

Initial evidence suggests that suppressing a thought prior to sleep results in subsequent dreaming of that thought. The present research examined the influence of cognitive load on dreaming following suppression. In Experiment 1, 100 participants received either a suppression instruction or no instruction for an intrusive thought prior to sleep, and subsequently completed a dream diary. Participants instructed to suppress reported dreaming about the target thought more than controls; dream rebound was predicted by poorer performance on a working memory task. In Experiment 2, 126 participants received either a suppression instruction or no instruction for an intrusive thought prior to sleep, and half of participants also had cognitive load of learning a 9-digit number. Participants receiving the suppression instruction under cognitive load reported greater dream rebound than other participants. These findings indicate that thought suppression prior to sleep leads to dream rebound, and this effect is enhanced by cognitive load.
