Effectiveness of two smoking prevention programs according to type of applicator

Although research on the prevention of drug use has shown that the effectiveness of programs depends partly on who applies them, the results of studies designed to clarify this issue are contradictory. This study compared the effects on smoking, in the short and medium term, of the implementation of two school-based prevention programs, depending on the type of applicator. The sample was made up of 200 seventh-grade students distributed among five experimental conditions: four of intervention, in which the programs were implemented by teachers from the school or by external psychologists, and one of control. The results show that teachers applying the Barbacana program and psychologists applying the Construyendo Salud (Building Health) program succeeded in reducing the incidence of cigarette smoking (BR-teachers 15%; C.S-psychologists 5%) and strengthening attitudes against smoking. An interaction effect between type of program and type of applicators was clearly observed.     

Interactive elements for dynamically linked multiple representations in computer simulations

Seventy‐three students learned central concepts about signal detection theory with an introductory text followed by a computer simulation. Each learner was randomly assigned to one of the three treatment groups: text boxes, scrollbars or drag and drop opportunities to modify parameters in the simulation. These three interactive elements were used for linking the different multiple representations in the simulation dynamically. Retention and transfer test, evaluation of the instructional material as well as time spent with the simulation were used as dependent measures. Learners who had to use scrollbars or had to modify parameters per drag and drop performed better on transfer, but not on retention, than did learners who had to use text boxes. Learners who had to modify parameters per drag and drop also evaluated the instructional material better than did learners who had to use text boxes. These results are consistent with the split‐attention principle. Copyright © 2009 John Wiley & Sons, Ltd.     

The transfer of Crel contextual control (same,opposite, less than,more than) through equivalence relations

According to Relational Frame Theory (RFT) C_rel denotes a contextual stimulus that controls a particular type of relational response (sameness, opposition, comparative, temporal, hierarchical etc.) in a given situation. Previous studies suggest that contextual functions may be indirectly acquired via transfer of function. The present study investigated the transfer of C_rel contextual control through equivalence relations. Experiment 1 evaluated the transfer of C_rel contextual functions for relational responses based on sameness and opposition. Experiment 2 extended these findings by evaluating transfer of function using comparative C_rel stimuli. Both experiments followed a similar sequence of phases. First, abstract forms were established as C_rel stimuli via multiple exemplar training (Phase 1). The contextual cues were then applied to establish arbitrary relations among nonsense words and to test derived relations (Phase 2). After that, equivalence relations involving the original C_rel stimuli and other abstract forms were trained and tested (Phase 3). Transfer of function was evaluated by replacing the directly established C_rel stimuli with their equivalent stimuli in the former experimental tasks (Phases 1 and 2). Results from both experiments suggest that C_rel contextual control may be extended via equivalence relations, allowing other arbitrarily related stimuli to indirectly acquire C_rel functions and regulate behavior by evoking appropriate relational responses in the presence of both previously known and novel stimuli.     

Problematic dyadic interaction among toddlers and their polydrug‐cocaine‐using mothers

Dyadic interactions between 84 at‐risk toddlers and their nondrug‐, polydrug‐non‐cocaine‐, or polydrug‐cocaine‐using mothers were examined during unstructured play. Coded videotaped behaviors revealed two maternal constructs (interactive competence, maladaptive engagement) and three toddler constructs (responsiveness, active positive initiation, play). Cocaine‐using mothers displayed more maladaptive engagement than did prenatal nondrug users; however, poorer interactive competence further distinguished them from polydrug‐but‐noncocaine users. Toddlers of cocaine‐using mothers displayed less responsiveness and positive initiation than non‐drug‐group peers; however, these behaviors did not reliably differ from polydrug‐non‐cocaine counterparts. Play interest remained relatively similar across groups. Results suggest that difficulties in social interaction appear to continue among cocaine‐using mothers during dyadic exchanges with their offspring in the second year; however, toddler deficits do not appear to be greater than those experienced by polydrug‐non‐cocaine counterparts.     

Treating chronic worry: Psychological and physiological effects of a training programme based on mindfulness

The present study examines psychological and physiological indices of emotional regulation in non-clinical high worriers after a mindfulness-based training programme aimed at reducing worry. Thirty-six female university students with high Penn State Worry Questionnaire scores were split into two equal intervention groups: (a) mindfulness, and (b) progressive muscle relaxation plus self-instruction to postpone worrying to a specific time of the day. Assessment included clinical questionnaires, daily self-report of number/duration of worry episodes and indices of emotional meta-cognition. A set of somatic and autonomic measures was recorded (a) during resting, mindfulness/relaxation and worrying periods, and (b) during cued and non-cued affective modulation of defence reactions (cardiac defence and eye-blink startle). Both groups showed equal post-treatment improvement in the clinical and daily self-report measures. However, mindfulness participants reported better emotional meta-cognition (emotional comprehension) and showed improved indices of somatic and autonomic regulation (reduced breathing pattern and increased vagal reactivity during evocation of cardiac defense). These findings suggest that mindfulness reduces chronic worry by promoting emotional and physiological regulatory mechanisms contrary to those maintaining chronic worry.     

Lipopolysaccharide-induced experimental immune activation does not impair memory functions in humans

Reconsolidation studies have led to the hypothesis that memory, when labile, would be modified in order to incorporate new information. This view has reinstated original propositions suggesting that short-term memory provides the organism with an opportunity to evaluate and rearrange information before storing it, since it is concurrent with the labile state of consolidation. The Chasmagnathus associative memory model is used here to test whether during consolidation it is possible to change some attribute of recently acquired memories. In addition, it is tested whether these changes in behavioral memory features can be explained as modifications on the consolidating memory trace or as a consequence of a new memory trace. We show that short-term memory is, unlike long-term memory, not context specific. During this short period after learning, behavioral memory can be updated in order to incorporate new contextual information. We found that, during this period, the cycloheximide retrograde amnesic effect can be reverted by a single trial in a new context. Finally, by means of memory sensitivity to cycloheximide during consolidation and reconsolidation, we show that the learning of a new context (CS) during this short-term memory period builds up a new memory trace that sustains the behavioral memory update.     

Prolonged institutional rearing is associated with atypically large amygdala volume and difficulties in emotion regulation

Early adversity, for example poor caregiving, can have profound effects on emotional development. Orphanage rearing, even in the best circumstances, lies outside of the bounds of a species-typical caregiving environment. The long-term effects of this early adversity on the neurobiological development associated with socio-emotional behaviors are not well understood. Seventy-eight children, who include those who have experienced orphanage care and a comparison group, were assessed. Magnetic resonance imaging (MRI) was used to measure volumes of whole brain and limbic structures (e.g. amygdala, hippocampus). Emotion regulation was assessed with an emotional go-nogo paradigm, and anxiety and internalizing behaviors were assessed using the Screen for Child Anxiety Related Emotional Disorders, the Child Behavior Checklist, and a structured clinical interview. Late adoption was associated with larger corrected amygdala volumes, poorer emotion regulation, and increased anxiety. Although more than 50% of the children who experienced orphanage rearing met criteria for a psychiatric disorder, with a third having an anxiety disorder, the group differences observed in amygdala volume were not driven by the presence of an anxiety disorder. The findings are consistent with previous reports describing negative effects of prolonged orphanage care on emotional behavior and with animal models that show long-term changes in the amygdala and emotional behavior following early postnatal stress. These changes in limbic circuitry may underlie residual emotional and social problems experienced by children who have been internationally adopted.     

The lay distinction between primary and secondary emotions: A spontaneous categorization?

In line with the psychological essentialism perspective, Leyens et al. ( 13 2000) have hypothesized that people attribute different essences to groups and that they attribute more uniquely human characteristics to their own group than to out‐groups. Leyens et al. have focused on two types of emotions, which in Roman languages have specific labels, such as sentimientos and emociones in Spanish. A cross‐cultural study showed that sentimientos (or secondary emotions) are considered uniquely human emotions whereas emociones (or primary emotions) are perceived as nonuniquely human emotions. The present study focuses on whether this categorization into primary and secondary emotions is a spontaneous distinction that people use in their everyday lives, or whether, on the contrary, it is the result of experimental demands. The paradigm “Who says what to whom” was used to test this question. Geometrical shapes of different colours were systematically associated with different stimuli that varied in meaningfulness. In a first condition, shapes were associated with small or large items of furniture (meaningful categories) and with primary and secondary emotions. In a second condition, the items of furniture were replaced by words ending with a vowel or a consonant (meaningless categories). Subsequently, participants had to recognize which shape was associated with each stimulus. Intra‐category errors were significantly more numerous than inter‐category errors, except for the words ending with a vowel or a consonant. Stated otherwise, types of emotions were recognized like the meaningful difference between items of furniture. These results show that the distinction between primary and secondary emotions is an implicit one that people use spontaneously, and not as a result of task demands. The findings are discussed from the perspective of psychological essentialism and inter‐group relations.     

A cross-cultural study of trait self-enhancement, explanatory variables, and adjustment

We investigated trait self-enhancement, explanatory variables, and adjustment in European American (n = 141), Asian American (n = 72), Mexican (n = 141), and Filipino (n = 174) college students. Consistent with trait perspectives, students in all cultural groups rated their traits with moderate to high accuracy, using peer ratings as a criterion. European Americans did not exhibit self-enhancement relative to peers, but both self and peer ratings were higher (i.e., more positive) for European Americans than for the other three groups. Support was found for some, but not all, cultural psychology explanations of self-enhancement. In all cultural groups, self-enhancement was more associated with personal (intrapsychic) adjustment than interpersonal adjustment, as judged by peers. The results provided support for an integration of trait and cultural psychology perspectives.     

Les objets connectés et applications de santé : étude exploratoire des perceptions,usages (ou non) et contextes d’usage

In a contemporary context of major health challenges, the market of digital technologies has increasingly developed in past years. This article aims to explore main profiles of use in relation to connected objects and health apps, as well as attitudes related to uses, non-uses and contexts of use. Therefore, our objective is to contribute to the scientific debate by proposing an empirical study in psychology that focusses on the perspectives of consumers and non-consumers of these technologies in the French-speaking part of Switzerland. To do this, a survey was conducted among participants of a large public health exhibition (n = 760). According to our results, the majority of respondents declare not having a connected object/health app and a third of non-users does not intend to acquire such technologies. Also, there is a trend among younger generations to have a connected object/health app. Concerning the contexts of use, such technologies are employed to self-track physical activity and eating practices. The degree of satisfaction of such use is rather high. Given these results, our analyses point out a divide within our sample, between individuals who seem resistant and declare not willing to have this kind of technology and those who use it in the long run. These results cast new light upon concrete uses and contexts of use among consumers and non-consumers of connected objects/health apps beyond techno-scientific promises that prevail today in our societies.
