Weak ventral striatal responses to monetary outcomes predict an unwillingness to resist cigarette smoking

As a group, cigarette smokers exhibit blunted subjective, behavioral, and neurobiological responses to nondrug incentives and rewards, relative to nonsmokers. Findings from recent studies suggest, however, that there are large individual differences in the devaluation of nondrug rewards among smokers. Moreover, this variability appears to have significant clinical implications, since reduced sensitivity to nondrug rewards is associated with poorer smoking cessation outcomes. Currently, little is known about the neurobiological mechanisms that underlie these individual differences in the responsiveness to nondrug rewards. Here, we tested the hypothesis that individual variability in reward devaluation among smokers is linked to the functioning of the striatum. Specifically, functional magnetic resonance imaging was used to examine variability in the neural response to monetary outcomes in nicotine-deprived smokers anticipating an opportunity to smoke—circumstances found to heighten the devaluation of nondrug rewards by smokers in prior work. We also investigated whether individual differences in reward-related brain activity in those expecting to have access to cigarettes were associated with the degree to which the same individuals subsequently were willing to resist smoking in order to earn additional money. Our key finding was that deprived smokers who exhibited the weakest response to rewards (i.e., monetary gains) in the ventral striatum were least willing to refrain from smoking for monetary reinforcement. These results provide evidence that outcome-related signals in the ventral striatum serve as a marker for clinically meaningful individual differences in reward-motivated behavior among nicotine-deprived smokers.     

Academic goals and learning strategies in secondary education Spanish students with social anxiety / Metas académicas y estrategias de aprendizaje en estudiantes españoles de Educación Secundaria Obligatoria con ansiedad social

The purpose of this study was to analyse the relationship between high social anxiety, academic goals and learning strategies in a sample of 2,022 (51.1% male) Spanish adolescents aged 12–16. The Social Phobia and Anxiety Inventory (SPAI), Achievement Goal Tendencies Questionnaire (AGTQ) and Learning and Studies Skills Strategies Inventory — High School Version (LASSI-HS) were used to assess the variables. The results showed no statistically significant differences in goal orientations between students with and without high social anxiety. However, students with high social anxiety used learning strategies significantly less. In addition, the logistic regression results indicated that high social anxiety acts as a significant predictor for setting social reinforcement goals and learning and study strategies.     

Theoretical trajectories: Dreams and dreaming from Freud to Bion

This paper aims at comparing Freud's and Bion's conceptual models on dreams and dreaming. Beyond both authors’ shared disposition vis‐à‐vis problems posed by knowledge, a critical gap opens regarding their differing clinical practices. It is hypothesized that their ideas do not belong to irreconcilable paradigms, but that there are continuities besides discontinuities more frequently highlighted between Freudian statements on psychic functioning – described in his theory on dreams – and Bion's findings in his development of both the original theory and the connections between dreaming and thinking. Firstly, Freud's and Bion's epistemological sources are examined as well as their creative use and historical environment. Then certain general theoretical and clinical issues are considered concerning their theories on dreams, the evolution of their ideas and corresponding clinical contexts. In a third section, their confluences and dissimilarities are dealt with, including clinical vignettes belonging to the authors to illustrate their interpretative modes of working. This is meant to show both an implicit theoretical–clinical complementarity and the fact that, though their routes bifurcate about the function of dreams, there remain connecting paths. Lastly, the final remarks review certain issues that have frequently been controversial between these lines of thought.     

Mother and self-representations: investigating associations with symptomatic behavior and academic competence in middle childhood

This article reports two studies examining the content and structural aspects of maternal and self-representations in middle childhood in two prospective studies of 9 to 11-year-old children, their stability over time and interrelations, and their contribution to symptomatology and academic functioning. In Study 1 (N=169), content and structural dimensions of participants' open-ended narratives of self and mother were assessed, and their factor structure was replicated across two consecutive measurement waves carried out a year apart. In Study 2 (N=137), using an independent sample, the authors investigated the associations of self- and maternal representations with teachers' subsequent reports of children's internalizing and externalizing symptomatology and academic competence. It was assumed that dimensions of self-representations played a mediating role in the prediction of children's symptomatology and competence by their maternal representations. Results corroborated the existence of interdependent but distinct representations of self and mother in middle childhood, as well as the stability over time of the structural and thematic aspects within each representation. The content of the self- and maternal representations was found to associate with observed symptomatic behavior, while their structure associated with children's academic competence. In addition, results indicated that self-representation content mediates the association of maternal representation content with subsequent symptomatic behavior. Findings are discussed in the light of the differentiation and interdependence of self- and maternal representations in middle childhood.     

Contextual Variations of Infrahumanization: The Role of Physical Context and Territoriality

The malleability of the infrahumanization bias was tested varying the physical context in which the ingroup and the outgroup target were assessed. Using a sequential priming paradigm, Study 1 replicated the infrahumanization bias in a neutral context. Study 2 tested the hypothesis that there are contextual variations in infrahumanization. Specifically, Black targets were infrahumanized in a context familiar to White participants, and not in an unfamiliar context. Study 3 revealed that participants’ threat perceptions were reduced when ingroup targets appeared in familiar context, compared to Black targets. Theoretical implications for the infrahumanization bias are discussed.     

Performance in Autobiographical Memory of Older Adults with Depression Symptoms

The aim of this study was to compare the performance in the Autobiographical Memory Test in older adults with high scores on depression symptoms (HDS) compared with a matched group with low scores on depression symptoms (LDS) according to the clinical cut‐off of the Centre for Epidemiological Studies Depression Scale. Participants were asked to generate specific autobiographical memories in response to a series of positive and negative cue words. Latencies of responses for each item were also scored. LDS participants showed a higher proportion of specific memories than HDS participants. Latencies of responses to positive and negative cues were greater for HDS than LDS. Specific autobiographical memory was positively associated with Life Satisfaction. Cognitive emotional changes in the function of memory with age are suggested as a possible explanation for the findings. Copyright © 2012 John Wiley & Sons, Ltd.     

Cue competition effects in the planarian

The learning abilities of planarian worms (Dugesia tigrina) were assessed by using a number of Pavlovian conditioning paradigms. Experiment 1 showed that planaria were susceptible to basic conditioning in that they readily developed a conditioned response to a change in ambient luminance when it was consistently paired with an electric shock over a number of trials. In Experiment 2, the change in luminance was presented in a compound with a vibration stimulus during conditioning. Subsequent tests revealed poor conditioning of the elements compared with control groups in which the animals were conditioned in the presence of the elements alone, an instance of overshadowing. In Experiment 3, pre-training of one of the elements before compound conditioning resulted in blocking of learning about the other element. These results add to other studies that have reported cue competition effects in animal species belonging to different phyla (chordate, mollusk, arthropod), suggesting that learning in these phyla could be ruled by similar principles. The results are discussed adopting an evolutionary-comparative approach.     

Job insecurity climate's influence on employees' job attitudes: Evidence from two European countries

An important amount of literature about job insecurity and its consequences has been developed during the past few decades (Sverke, Hellgren, & Näswall, 2002 Sverke, M., Hellgren, J. and Näswall, K. 2002. No security: A meta-analysis and review of job insecurity and its consequences. Journal of Occupational Health Psychology, 7(3): 242–264. [Crossref], [PubMed] , [Google Scholar]). Most of this research has focused on an individual-analysis perspective, without taking into account social context. Although job insecurity climate has not been empirically examined, several authors have implicitly assumed that job insecurity contexts exist in some organizations where layoffs have occurred. Therefore, they examined layoff survivors' reactions. From this perspective, the aim of this study was to validate the job insecurity climate concept and examine its influence on employees' job attitudes. In order to provide additional support, this objective was examined in two samples: 428 employees belonging to 20 Spanish organizations and 550 employees in 18 Belgian organizations. The results showed that job insecurity climate emerged within the organizations in both samples, and that it influenced employees' job satisfaction and organizational commitment above and beyond individual perceptions of job insecurity in the Spanish sample. The implications and limitations of this study are discussed.     

Religious upbringing and current religiosity in Spanish nursing and medicine students

The influence of religious education in the family upon current spiritual and religious tendencies was assessed in a sample of 599 Spanish nurse and medicine students using a religiosity scale and answers to a series of belief/disbelief statements. Results showed that nursing and medicine students were equally low-religious, with no differences in religiosity total scores between participants coming from religious families; however, medical students coming from nonreligious families showed higher religiousness than the corresponding nursing trainees. This distinction appeared both across religiosity items and in a variety of responses to belief/disbelief of Christian/secular assertions. Regression analysis showed that religious family background was a consistent predictor of religious beliefs at young adulthood, and its influence was higher for medical students. In addition to establish religious upbringing as an important factor modulating enduring religiosity, these findings provide distinctions between nurse and medical trainees, and reproduce, in a Spanish mainly catholic sample, the structure of religiosity factors previously found on North American mainline protestants.     

Using Narrative Approaches to Teach Multicultural Counseling

Narrative approaches to teaching multicultural counseling can assist students in integrating course content with a sense of self. Narrative teaching strategies follow a postmodern view of learning—that is, that truth is constructed through the interaction of participants. Justification for narrative approaches to teaching multicultural counseling and narrative are introduced. Los enfoques narrativos para enseñar la consejería multicultural pueden ayudar a los estudiantes a integrar el contenido del curso con su sentido de ser. Las estrategias de la enseñanza narrativa siguen un panorama postmoderno de aprendizaje—que considera que la verdad se construye por la interacción de participantes. La justificación para enfoques narrativos para enseñar la consejería multicultural y la narrativa se introducen.
