Stimulus representations in human Pavlovian conditioning: Implications of missing negative transfer across response systems

Three Pavlovian conditioning experiments with human participants are reported, which investigated whether common or separate stimulus representations are involved in solving nonlinear discrimination tasks in different response systems. In our experiments we made use of a negative transfer effect between positive and negative patterning. Experiment 1 specified the conditions under which such a negative transfer effect occurs in human eyelid conditioning. Experiments 2 and 3 investigated whether a similar effect also occurs if two response systems- the eyelid and the skin conductance response system- are trained with trials of both types being randomly interleaved. The presence or absence of a negative transfer effect indicates whether or not the stimulus representations involved in the two conditioning processes overlap. The findings are discussed within the framework of a neuropsychological model of hippocampal function. The results suggest that the representations are distinct and thus support the idea of acquired equivalence and distinctiveness of stimulus representations.     

Nine-month-old infants generalize object labels, but not object preferences across individuals

As with all culturally relevant human behaviours, words are meaningful because they are shared by the members of a community. This research investigates whether 9-month-old infants understand this fundamental fact about language. Experiment 1 examined whether infants who are trained on, and subsequently habituated to, a new word-referent link expect the link to be consistent across a second speaker. Experiment 2 examined whether 9-month-old infants distinguish between behaviours that are shared across individuals (i.e. words) from those that are not (i.e. object preferences). The present findings indicate that infants as young as 9 months of age expect new word-referent links, but not object preferences, to be consistent across individuals. Thus, by 9 months, infants have identified at least one of the aspects of human behaviour that is shared across individuals within a community. The implications for children's acquisition of language and culture are discussed.     

Daily variability in working memory is coupled with negative affect: the role of attention and motivation

Across days, individuals experience varying levels of negative affect, control of attention, and motivation. We investigated whether this intraindividual variability was coupled with daily fluctuations in working memory (WM) performance. In 100 days, 101 younger individuals worked on a spatial N-back task and rated negative affect, control of attention, and motivation. Results showed that individuals differed in how reliably WM performance fluctuated across days, and that subjective experiences were primarily linked to performance accuracy. WM performance was lower on days with higher levels of negative affect, reduced control of attention, and reduced task-related motivation. Thus, variables that were found to predict WM in between-subjects designs showed important relationships to WM at the within-person level. In addition, there was shared predictive variance among predictors of WM. Days with increased negative affect and reduced performance were also days with reduced control of attention and reduced motivation to work on tasks. These findings are in line with proposed mechanisms linking negative affect and cognitive performance.     

I crashed the boat and wept: Localizing the “field” in critical geographic practice

Geographers often practice “fieldwork” for research, physically traveling between field and the academy. While critical scholars have contemplated their positionality in the field, what gets overlooked is how academic constructions of their “field” can discount indigenous peoples’ knowledges of “home.” Because academics’ representations of “the field” affirm the subject/object binary, this ontology allows indigenous peoples’ knowledges to be criticized in their emotional expressions of their homelands. In this paper I describe my practices of “field” work to disrupt this ontology—and in so doing, what emerges is my deeply emotional engagement with this “field,” produced through the network of materialities and beings with whom I worked. Network ontologies allow more space for discussing the emotional and affective experiences of a field site, including researcher uncertainty and responsibility. Attending to both conscious and unconscious motives to action is a more rigorous critical practice, and representing emotions can at once benefit research goals (emotional engagements leading to new insights), and lead to new politics of knowledge production and representation: such as opening a space for indigenous peoples to be recognized as legitimate spokespersons about their own beloved landscapes.     

Acculturation,self‐construal,mental and physical health: An explorative study of East Asian students in Germany

The present study explores acculturation and its associated aspects of two East Asian student groups with different levels of exposure to German culture (100 international students from East Asian countries [IS]; 61 second generation students of East Asian descent [SGS]). First, we investigated the relationships between acculturation, self‐construal, depressive and somatic symptoms, and differences between the student groups in these variables. Second, the four acculturation types (integration, assimilation, separation and marginalization) were examined regarding their relationship to self‐construal and health outcomes. The results showed that the acculturation dimensions (mainstream, heritage) were relevant to the level of depressive symptoms for IS which was not the case for SGS. Furthermore, IS reported more somatic symptoms whereas there was no difference between the two groups in the level of depressive symptoms. In the analysis of acculturation types, assimilated and integrated students were characterized by high independent self‐construal, while separated and integrated students showed high interdependent self‐construal. Assimilated students displayed the least depressive symptoms of all acculturation groups. This study highlights different characteristics of East Asian students in acculturation, self‐construal and health outcomes, and discusses the complexity of the relationships between acculturation types and health.     

Social support from fellow group members triggers additional effort in groups

This research demonstrates social support from fellow group members as unique trigger of additional effort and performance in groups. Support‐induced effort gains are shown both compared with groups without social support and individual work. Study 1 examined existing beliefs about motivating group work among employees with professional group work experience (n = 130). The results revealed social support as one of the most frequently reported sources of group‐induced effort gains. Study 2 explored self‐reported effort intentions in group training scenarios among athletes (n = 94). Finally, Study 3 examined performance as a manifest indicator of effort in an experimental persistence task among students (n = 88). The results of Study 2 and Study 3 showed significant gains due to social support in both self‐reported effort and manifest performance, respectively. Together, the results demonstrate that receiving social support from fellow group members leads to higher effort in groups at the level of existing beliefs about motivating group work, at the level of effort intentions, and at the level of manifest performance behavior. The observed findings cannot be explained by established sources of motivation gains in groups such as social comparison or social indispensability. Copyright © 2014 John Wiley & Sons, Ltd.     

Wohlbefinden,Burn-out und Ressourcen bei Psychotherapeuten

Background

Well-being and its correlates have rarely been investigated in psychotherapists. Results from research on other occupational groups have shown that subjective and work-related well-being are both associated with performance and motivation as well as with mental and physical health. Therefore, personal and job-related resources of practicing psychotherapists were investigated in this study in order to assess their associations with well-being.

Method

A total of 771 psychotherapists filled in an online questionnaire including questions concerning well-being (WHO-Five Well-being Index, WBI-5), burnout (Maslach Burnout Inventory, MBI), and personal (Psychological Capital Questionnaire, PCQ) as well as job-related (Dutch Questionnaire on Work Experience, VBBA) resources.

Outcomes

Of the participants 45?% reported that they were suffering from high emotional exhaustion. Over 30?% reported a reduced subjective well-being, while more extensive professional experience was associated with better well-being. Psychotherapists reported optimism and hope to be the most important personal resources, whereas opportunities for personal and professional development were the most important job-related resources.

Conclusions

The study identified personal and job-related resources which may be relevant for different aspects of well-being in psychotherapists.     

Scham und Familienbeziehungen bei Bulimie

Background

Empirical studies show a relationship between family factors and disturbed eating behavior. Feelings of shame are associated with a higher level of eating disorder symptoms and with family relations perceived as being dysfunctional. Thus shame can be understood as a mediator of the relationship between dysfunctional family relations and eating disorder symptoms.

Material and methods

For 69 female patients, including 55 with bulimia nervosa and 14 with eating disorder not otherwise specified (EDNOS) between 14 and 22 years of age, who participated in a comparative study of psychotherapy outcome, eating disorder symptoms (EDI, EDE-Q), general psychiatric symptoms severity (SCL-90R), level of shame (TESE-KJ) and perceived family relations (FB-A) were measured at the beginning of psychotherapy.

Results

The higher the feeling of shame the more dysfunctional the perceived family relationships were and the more the eating disorders and general symptoms severity were reported. Shame was a partial mediator of the relationship between family functionality and symptoms.

Discussion

Feelings of shame could originate in dysfunctional family relationships but could also evoke more negative perceptions of interpersonal relationships. The direction of causality could not be proven in the correlative design; nevertheless, shame contributes to an understanding of the mechanisms between dysfunctional family relationships and eating disorder symptoms.     

The Happiness-Enhancing Activities and Positive Practices Inventory (HAPPI): Development and Validation

Whilst research indicates that happiness-enhancing activities can boost happiness, the measurement of intentional happiness-enhancing activities has thus far been inadequate. This paper describes the development and initial empirical testing of the Happiness-enhancing Activities and Positive Practices Inventory (HAPPI), a self-report inventory designed to measure older adults’ happiness-enhancing activities. An exploratory factor analysis of the HAPPI responses from a population sample of 2,313 older adults identified four factors: self-concordant work, personal recreation and people, spiritual and thought-related, and goal-focused activities. Results demonstrated evidence of reliability, convergent and discriminant validity and support for the predictive utility of the HAPPI. The subscales derived from the factor analysis correlated as expected with measures of subjective well-being and other relevant measures, and showed moderately high subscale intercorrelations and satisfactory internal consistency. The results provide a basis for continuing to develop and clarify the types of intentional activities people engage in. Differences between our results and studies with younger adults are discussed, including possible age-related differences in the types of happiness-enhancing activities engaged in and the potential influence of these activities on happiness. The HAPPI is a relatively brief, easily administered inventory that shows promise as a useful tool for the measurement of happiness-enhancing activities and can be employed to follow cohorts to determine which domains demonstrate the greatest contribution to happiness and other well-being outcomes, which have implications for social policy, education and intervention programmes to enhance well-being.
