On the modularity of implicit sequence learning: independent acquisition of spatial, symbolic, and manual sequences

Learning sequential structures is of fundamental importance for a wide variety of human skills. While it has long been debated whether implicit sequence learning is perceptual or response-based, here we propose an alternative framework that cuts across this dichotomy and assumes that sequence learning rests on associative changes that can occur concurrently in distinct processing systems and support the parallel acquisition of multiple uncorrelated sequences. In three experiments we used a serial search task to test critical predictions of this framework. Experiments 1 and 2 showed that participants learnt uncorrelated sequences of auditory letters and manual responses, as well as sequences of visual letters, spatial locations, and manual responses simultaneously, as indicated by a reliable response time (RT) cost incurred by occasional deviants violating either of the sequences. This RT cost was reliable even when participants showing explicit knowledge were excluded. In Experiment 3 learning of spatial and nonspatial sequences was functionally dissociated: whereas a spatio-motor distractor task disrupted learning of location but not of letter sequences, a phonological distractor task had the reverse effect. The distractor tasks thus did not reduce unspecific attentional resources, but selectively disrupted the formation of sequential associations within spatial and nonspatial processing dimensions. These results support the view that implicit sequence learning rests on experience-dependent changes that can occur in parallel in multiple processing systems involved in spatial attention, object recognition, phonological processing, and manual response selection. The resulting dimension-specific sequence representations support independent predictions of what will appear next, where it will appear, and how one will have to respond to it.     

Can survival processing enhance story memory? Testing the generalizability of the adaptive memory framework

Research from the adaptive memory framework shows that thinking about words in terms of their survival value in an incidental learning task enhances their free recall relative to other semantic encoding strategies and intentional learning (Nairne, Pandeirada, & Thompson, 2008). We found similar results. When participants used incidental survival encoding for a list of words (e.g., "Will this object enhance my survival if I were stranded in the grasslands of a foreign land?"), they produced better free recall on a surprise test than did participants who intentionally tried to remember those words (Experiment 1). We also found this survival processing advantage when the words were presented within the context of a survival or neutral story (Experiment 2). However, this advantage did not extent to memory for a story's factual content, regardless of whether the participants were tested by cued recall (Experiment 3) or free recall (Experiments 4-5). Listening to a story for understanding under intentional or incidental learning conditions was just as good as survival processing for remembering story content. The functionalist approach to thinking about memory as an evolutionary adaptation designed to solve reproductive fitness problems provides a different theoretical framework for research, but it is not yet clear if survival processing has general applicability or is effective only for processing discrete stimuli in terms of fitness-relevant scenarios from our past.     

Unmitigated agency, social support, and psychological adjustment in men with cancer

Unmitigated agency (UA), a gender-linked characteristic, has been associated with poorer cancer adjustment. Support from one's social network typically predicts adjustment but may be poorly matched to UA. The influence of UA on the utility of social support on adjustment over time is examined. Men with cancer (N=55) were assessed initially and 6 months later on three indicators of adjustment. Multilevel modeling analyses varied by adjustment indicator. UA was associated with increased cancer-related psychosocial symptoms but not depressive symptoms or cancer-related thought intrusion. Social support predicted fewer depressive symptoms and less cancer-related thought intrusion. However, a cross-level interaction revealed that the utility of social support on cancer-related thought intrusion was weaker for men with greater levels of UA. Men with cancer likely respond differently to changes in social support depending on their endorsement of UA.     

Assessing Parenting Skills and Attitudes: A Review of the Psychometrics of Parenting Measures

There are many measures that assess parenting skills or practices, such as behavior, beliefs, coping mechanisms, reactions to stress, or discipline. However, little is known about the psychometric quality of these parenting measures. This information is essential for practitioners and researchers to aide in the selection of the most valid and reliable measures to assess parenting behavior or attitudes. This study examined the psychometric quality among parenting measures published from 1985 to 2009. After the initial search 164 measures were identified, but were reduced to 25 measures that supplied some degree of psychometric information, were published in the United States or Canada, and were in English. Measures were compared across numerous categories including respondent type, norming data, administration type, and ten psychometric variables such as internal consistency, content validity, and predictive validity. Out of the 25 measures, seven had no acceptable psychometric properties, seven had only 1–2 acceptable ratings on psychometric properties, six had between 3 and 4 acceptable psychometric ratings, none had between 5 and 6 acceptable ratings, and only five had strong psychometric properties in seven or more of the 10 categories. Likewise, only five measures provided and norming information and 14 measures provided scoring procedures. Implications, limitations, and recommendations for future research are discussed.     

Reducing Psychotropic Medications in an Intensive Residential Treatment Center

Medication rates in behaviorally disordered children and youth have greatly increased to current high levels and are very controversial. This study examined changes in psychotropic medication use, levels of behavioral disturbance, and use of personal restraint and seclusion in a population of youth with serious behavioral disorders receiving medically directed cognitive-behavioral treatment in an intensive residential setting. The hypothesis was that there would be significant reductions in medication rates, without the unintended consequences of increased rates of problem behavior or offsetting increases in the use of seclusion or personal restraint. Results showed significant reductions in both the number of youth on medication and the average number of psychotropic medications during the residential stay. There were also significant reductions in behavioral disturbance, seclusions, and personal restraints. These results demonstrate that psychotropic medication can be significantly reduced without increases in problem behavior or the use of seclusions or personal restraints. We conclude that it is possible to significantly reduce psychotropic medication rates to far more conservative levels within the context of a clinically directed cognitive-behavioral treatment milieu.     

Psychotropic Medication Management Within Residential Treatment Centers: Physician Opinions About Difficulties and Barriers

Research has shown that between 40 and 98 % of youth entering residential treatment are taking at least one psychotropic medication and that psychotropic medication management is often an integral component of treatment in residential settings. To determine physician opinion about the difficulty of managing psychotropic medications for youth in residential treatment and to determine the resources that are used in the process, a survey study was conducted. Overall, physicians indicated that youth involved in residential settings were much more complex than those in traditional outpatient settings, due to multiple mental health diagnoses, polypharmacy, and unknown treatment histories. They also reported that many existing resources are not applicable to youth, particularly those in residential settings, and that they are difficult to read and interpret.     

Interaction Between the Parenting Alliance and Parent–Child Activities in a Clinic-Referred Sample of 2 to 18-year-olds

Several decades of research have demonstrated a link between marital, parenting, and child domains. The present study examined the nature of these links by testing the moderating effect of the parent–child relationship on the association between the parenting alliance and internalizing and externalizing problems in 324 dual-parent families of 2-to-18-year-old clinic-referred youth. Findings indicated that positive parent–child activities directly related to children’s internalizing and externalizing problems, and modified the nature of the association between the parenting alliance and internalizing problems in families of 6-to-10-year-olds. Interestingly, in families where parents engaged in fewer positive activities with their children, a strong parenting alliance actually related to greater child internalizing problems. Findings support the importance of understanding the interaction between the marital and child domains in order to effectively intervene with families of children experiencing behavior problems.     

Lonely Adolescents and Their Best Friend: An Examination of Loneliness and Friendship Quality in Best Friendship Dyads

Friendship experiences have been shown to be important predictors of adolescents’ loneliness. The current study examined selection and socialization effects of loneliness within reciprocal best friendships, while controlling for friendship quality. Analyses were conducted on a sample of 884 adolescents (42.08% boys), making up 442 dyads, who were on average 13.51 years old (SD?=?1.37). Adolescents completed the peer-related loneliness subscale of the Loneliness and Aloneness Scale for Children and Adolescents as well as the Friendship Qualities Scale. A longitudinal actor-partner interdependence model, which accounts for the interdependencies in the data of best friends, suggested the presence of a selection effect for loneliness but no socialization effect. This finding within best friendships contrasts with studies on friendship networks where both selection and socialization were established.     

Seventh-day Adventist Clergy: Understanding Stressors and Coping Mechanisms

This article examines the extent and types of clergy stress, the strategies used in coping with stressors, and the relationship between stressors and coping mechanisms in a sample of 261 Seventh-day Adventist pastors in North America. The results indicate that the most commonly reported stressors in order are: (1) lack of social support, (2) financial stress, and (3) time and workload stress. In terms of coping strategies, pastors sought relief most often through: (1) reflective growth/internal change; (2) social/emotional coping; (3) passive coping; and lastly (4) action-oriented coping. Significant correlational relationships existed between passive coping and financial stress, relocating stress, and congregational stress. In addition, we found significant inverse correlations between coping through reflective growth or internal change and relocating stress and congregational stress. There were no significant relationships with action coping or social/emotional coping and any stressor. Multi-regression analysis reveals that passive coping strategies were significantly related to financial stress. Thus, the greater the financial stress, the more likely pastors were to engage in passive coping strategies. Other coping strategies showed no significant relationships when included in multi-regression analysis. We conclude with recommendations for Church administrators to address structures and practices in place for pastors including an expansion of coping mechanisms to help pastors address their stress.     

Normativity all the way down: from normative realism to pannormism

In this paper, I will give an argument for what I call pannormism, the view according to which if x instantiates a metaphysically basic normative property F, then whatever grounds the being of x also instantiates F. In slogan form: if there is normativity, there is normativity all the way down. Such pannormism is in many ways analogous to panpsychism, and my discussion also contains an important lesson for panpsychism, a way to avoid its so-called combination problem. In Sect. 1, I present the argument; in Sect. 2, I discuss its conclusion.
