Is prospective memory enhanced by cue-action semantic relatedness and enactment at encoding?

Benefits and costs on prospective memory performance, of enactment at encoding and a semantic association between a cue-action word pair, were investigated in two experiments. Findings revealed superior performance for both younger and older adults following enactment, in contrast to verbal encoding, and when cue-action semantic relatedness was high. Although younger adults outperformed older adults, age did not moderate benefits of cue-action relatedness or enactment. Findings from a second experiment revealed that the inclusion of an instruction to perform a prospective memory task led to increments in response latency to items from the ongoing activity in which that task was embedded, relative to latencies when the ongoing task only was performed. However, this task interference 'cost' did not differ as a function of either cue-action relatedness or enactment. We argue that the high number of cue-action pairs employed here influenced meta-cognitive consciousness, hence determining attention allocation, in all experimental conditions.     

Portuguese Validation of FACES-IV in Adult Children Caregivers Facing Parental Cancer

The purpose of the present study was to examine the psychometric properties of the FACES-IV in Portuguese caregivers of cancer patients. In this cross-sectional study, a sample of 214 adult children caregivers of cancer patients receiving chemotherapy, completed FACES-IV, Family Communication Scale (FCS), Family Satisfaction Scale (FSS), and Satisfaction with Social Support Scale (SSSS). Internal consistencies above .70 were found for all FACES-IV scales, except for Enmeshed and Rigid scales, as well as for the FCS, FSS, and SSSS (except for Intimacy). Strong correlations between FACES-IV and the validation scales FCS and FSS were found except for the Enmeshed and Rigid scales. Confirmatory analysis yielded an acceptable model for the six theoretical subscales. The discriminant analysis between problematic and non-problematic family systems showed results similar to the original study. These findings suggest that FACES-IV is a valid measure of family functioning in oncological family caregiving’s contexts.     

Group fixed-role therapy: A clinical application

Fixed-role therapy has primarily been seen as a form of individual therapy. However, Kelly 0955) suggested that it would provide an interesting and useful way of approaching group psychotherapy. This article illustrates the feasibility of Kelly's suggestion in a clinical setting. The group had 5 participants, all of whom had been referred for help with social anxiety or social phobia. Self-report measures were administered before and after group therapy, and the outcome was positive.     

Daily Interactions and Affect in Older Adulthood: Family,Friends, and Perceived Support

Research suggests that family and friend support differentially impact well-being, although relatively few studies investigate how these relationships function day-to-day. The first goal of the study was to explore how interactions with family and with friends related to individuals’ daily experience of positive and negative emotion. The second goal of the study was to determine whether the perception that others were available to provide a particular type of support moderated the relationship between friend and family support and well-being each day. Multilevel Random Coefficient Modeling illuminated these linkages in data from 96 participants from Successful Aging in Context: The Macroenvironment and Daily Lived Experience (M _Age = 67 years, SD _Age = 4.9 years; range 58–86 years). Results revealed significant relationships between affect balance and satisfaction with the amount of support provided by family and by friends; in general, older adults reported a higher ratio of positive to negative affect on days they were more satisfied with the amount of support received from each source. Results of Level-2 analyses suggested that the perception that others were available to provide tangible assistance strengthened the relationship between satisfaction with family support and daily well-being; likewise, the availability of emotional support and advice strengthened the daily friend support–affect balance association. Overall, results suggest that global perceptions that network members are available to provide different types of support differentially augment the relationships between the social support older adults receive from friends and family each day and well-being; in so doing, these results suggest ways in which older adults can benefit most from existing support.     

When friends exchange negative feedback

In four studies, we document an increase in the amount of negative feedback friends and colleagues exchange as their relationship deepens. We find that both actual and perceived relationship depth increase the amount of negative feedback people seek from and provide to each other, as well as their tendency to invest in a focal (relationship or performance) goal in response to negative feedback. The amount of positive feedback on goal pursuit, by contrast, remains stable as the relationship deepens. We attribute the increase in negative feedback to the different meaning of such feedback for people in deep versus shallow relationships: only in the context of deep relationships does negative feedback signal insufficient resource investment in the focal goal, and hence close friends and colleagues seek, provide, and respond to negative feedback.     

A New Normalization Strategy for the Implicational Fragment of Classical Propositional Logic

The introduction and elimination rules for material implication in natural deduction are not complete with respect to the implicational fragment of classical logic. A natural way to complete the system is through the addition of a new natural deduction rule corresponding to Peirce’s formula (((A → B) → A) → A). E. Zimmermann [6] has shown how to extend Prawitz’ normalization strategy to Peirce’s rule: applications of Peirce’s rule can be restricted to atomic conclusions. The aim of the present paper is to extend Seldin’s normalization strategy to Peirce’s rule by showing that every derivation Π in the implicational fragment can be transformed into a derivation Π′ such that no application of Peirce’s rule in Π′ occurs above applications of →-introduction and →-elimination. As a corollary of Seldin’s normalization strategy we obtain a form of Glivenko’s theorem for the classical {→}-fragment.     

Emotion affects action: Midcingulate cortex as a pivotal node of interaction between negative emotion and motor signals

Affective pictures drive the activity of brain networks and impact behavior. We showed previously that viewing unpleasant pictures interfered in the performance of a basic nonemotional visual detection task. In the present study, we employed functional magnetic resonance imaging to test the hypothesis that behavioral interference may result from the interaction between negatively valenced and motor-related signals in the brain. As in our previous study (Pereira et al., 2006), participants performed a simple target detection task that followed the presentation of unpleasant or neutral pictures. Our results revealed that an unpleasant emotional context modulated evoked responses in several regions engaged by the simple target detection task. In particular, the midcingulate cortex was recruited when participants performed target detection trials during the unpleasant context, and signal responses in this region closely mirrored the pattern of behavioral interference (as revealed via reaction time). Our findings suggest that the midcingulate cortex may be an important site for the interaction between negatively valenced signals and motor signals in the brain and that it may be involved in the implementation of defensive responses, such as freezing.     

Personal homepage construction as an expression of social development

In 2 studies, the authors explored preadolescent and adolescent use of personal homepages in relation to mastery and identity formation. In Study 1, the authors attempted to determine the prevalence of personal homepage and online journal (blog) construction among a random sample (N=500) of preadolescents and adolescents. Adolescents were more likely to create personal homepages or blogs than preadolescents. Creation was related to feelings of mastery, expressions of identity, and a means to socialize. In Study 2, the authors explored the relationship of homepages to mastery and identity formation by content analysis of a random sample of homepages. Results suggest children use personal homepages to express and explore their forming identities.     

Development and validation of a measure to assess head start children's appraisals of teacher support

In this study, we present data on the development of Young Children's Appraisals of Teacher Support (Y-CATS), a measure designed to explore children's perceptions of their relations with teachers along dimensions that comprise warmth, conflict, and autonomy. Three cohorts of Head Start children and prior Head Start attendees (N=364) served as the sample. Cohort 1 children (n₁=108) were in first grade, cohort 2 children (n₂=123) were in kindergarten, and cohort 3 children (n₃=133) attended the Head Start program. Factor analyses supported a three-factor solution, with acceptable internal consistency, along hypothesized dimensions. Males, compared to females, reported more conflictual relationships with their teachers. Conflict scores were particularly pronounced for African American males. Children's reports on the Y-CATS were significantly associated with academic achievement and with teachers' ratings of social skills and behavior problems.     

Validation of the Suicide Resilience Inventory-25 (SRI-25) in adolescent psychiatric inpatient samples

Resilience has been associated with a markedly decreased chance for risky behaviors following a trauma or other negative life event. This study examined the factor structure and psychometric properties of a self-report measure of resilience, the Suicide Resilience Inventory-25 (SRI-25; Osman et al., 2004 ), among psychiatric inpatient adolescents. In Study 1, we conducted confirmatory factor analysis to provide additional empirical support for the structure and invariance of the 3-factor model of the SRI-25 in youth samples, ages 14 to 17 years (N = 152 boys, 220 girls). Scale reliability analyses provided good evidence for internal consistency reliability of scores on the SRI-25 total and scales. In Study 2 (N = 30 boys, 40 girls), we presented data in support for the concurrent validity (i.e., known groups) of scores on the SRI-25. Additionally, we identified potential correlates for the SRI-25 total scale scores.
