Procrastination by pigeons: preference for larger, more delayed work requirements.

In three experiments, pigeons chose between alternatives that required the completion of a small ratio schedule early in the trial or a larger ratio schedule later in the trial. Completion of the ratio requirement did not lead to an immediate reinforcer, but simply allowed the events of the trial to continue. In Experiment 1, the ratio requirements interrupted periods in which food was delivered on a variable-time schedule. In Experiments 2 and 3, each ratio requirement was preceded and followed by a delay, and only one reinforcer was delivered, at the end of each trial. Two of the experiments used an adjusting-ratio procedure in which the ratio requirement was increased and decreased over trials so as to estimate an indifference point--a ratio size at which the two alternatives were chosen about equally often. These experiments found clear evidence for "procrastination"--the choice of a larger but more delayed response requirement. In some cases, subjects chose the more delayed ratio schedule even when it was larger than the more immediate alternative by a factor of four or more. The results suggest that as the delay to the start of a ratio requirement is increased, it has progressively less effect on choice behavior, in much the same way that delaying a positive reinforcer reduces it effect on choice.     

Social support and psychosocial competence: Explaining the adaptation to college of ethnically diverse students

Examined relationships among social support, psychosocial competence, and adaptation to college in a sample of 357 African American, Asian American, Latino, and white college students. Social support and active coping were significant predictors of adaptation to college, whereas locus of control was not. However, there was an interaction between ethnicity and locus of control indicating that although internal African American, Latino, and white students had higher adaptation-to-college scores than external students, the opposite was true for Asian Americans. The relationships among social support, internality, and active coping were also explored. Satisfaction with social support and internality were positively related to active coping, but locus of control and social support were unrelated. Active coping and internality were significantly related to each other for all groups except for African Americans. Although most relationships were the same across groups, these findings call attention to the role of ethnicity as a moderator of college adjustment processes.     

Decentered online Bible instruction: How active learning enhances the study of Scripture

The field of biblical studies lends itself well to decentered online learning – a kind that uses active learning to engage primary texts and their interpretations. Not only does such an approach work well in online and hybrid formats, it more readily welcomes readings that are more contextual, constructive, and collaborative. Three aspects best characterize a decentered approach to active learning online: an orientation toward primary texts, collaborative inquiry, and enhanced learner initiative. This essay describes the significance of each in turn, along with naming some best practices. I argue that this approach not only shifts focus toward learners and the learning environment, it works particularly well for teaching Bible courses online and in hybrid formats where interpretation of primary sources is the fundamental goal.     

Citizenship’s tangled web: Associations,gaps and tensions in formulations of European youth active citizenship across disciplines

Abstract

How does academic literature across various disciplines conceptualize and empirically address active citizenship? What are the potential benefits and dangers of dominant epistemological and ideological perspectives on ‘good citizenship’? Our paper engages with these questions by drawing on literature across 12 disciplines. We used textual analysis software T-LAB to quantify and visualize co-occurrences, word associations and thematic clusters in the abstracts of 770 texts gathered by eight country teams and original in-depth qualitative analyses of ideological positions and discourses taken up in a selection of key texts across the corpus. Our paper elaborates the findings: that many of the key themes surrounding young people and citizenship in the literature share little or no connection with European citizenship; that there is a significant gap in the literature on young European citizens; and that studies connected to internal, status-based factors connected to citizenship are far more prevalent than those examining external, practice-based factors or dissidence and dissent. Our conclusions examine the potential normative implications of the disjuncture between dominant conceptions and critical accounts of youth active citizenship.     

Why it is difficult to see the anima as a helpful object: critique and clinical relevance of the theory of archetypes

This paper is divided into three parts. The first deals briefly with more general aspects of the theory of archetypes (as conceived by Jung); the second examines the anima archetype in rather more detail, because it is, apart from the self, the main archetype in Jung's thought; and the third discusses the clinical repercussions of the anima theory and of the theory of the archetypes in general. The various references to Jung himself and certain circumstances of his life are included here on the assumption that personal problems in his biography contributed decisively to the constitution of his theory, so that deeper insights accure if they are taken into account.     

“I don't know but I know who to ask”: 12‐month‐olds actively seek information from knowledgeable adults

Active social communication is an effective way for infants to learn about the world. Do pre‐verbal and pre‐pointing infants seek epistemic information from their social partners when motivated to obtain information they cannot discover independently? The present study investigated whether 12‐month‐olds (N = 30) selectively seek information from knowledgeable adults in situations of referential uncertainty. In a live experiment, infants were introduced to two unfamiliar adults, an Informant (reliably labeling objects) and a Non‐Informant (equally socially engaging, but ignorant about object labels). At test, infants were asked to make an impossible choice—locate a novel referent among two novel objects. When facing epistemic uncertainty—but not at other phases of the procedure—infants selectively referred to the Informant rather than the Non‐Informant. These results show that pre‐verbal infants use social referencing to actively and selectively seek information from social partners as part of their interrogative communicative toolkit.

Procrastination: Different time orientations reflect different motives

Because procrastination concerns a person’s ability to meet deadlines, temporal dimension is clearly important to this personality construct. In the present study, the characteristic profile of arousal and avoidant motives of procrastinators were related to past, present, and future time conceptions. Participants (140 women, 135 men; mean age = 49.4, SD = 5.55) completed measures of arousal and avoidance procrastination, and time orientation. Results indicated that avoidant procrastination was associated negatively with present-fatalistic time orientation, and arousal procrastination was associated positively with present-hedonist and negatively with future time orientations. The variance accounted for by time orientations was modest, yet provides further evidence that there are distinct motives for chronic procrastination.

Countertransference as active imagination: imaginative experiences of the analyst

Active imagination is at the heart of Jung's elucidation of depth psychology. Yet, in the discourse of present day analytical psychology theory it is not always given the serious attention accorded to some other Jungian concepts. Active imagination emerges spontaneously within the 'third' area--the imaginal or dynamic field--in-between patient and analyst. It is commonly regarded as the patient's experience but I am proposing that, looked upon as the analyst's experience as well, active imagination offers a distinctly Jungian way of understanding some forms of countertransference. I am describing what I think many present-day analytical psychologists already do in their clinical practice but, as far as I know, it has not been theorized in quite this way before. The intention is to exploit the unique contribution of our Jungian heritage by reframing certain profoundly symbolic countertransference-generated imagery as active imagination. In this article these are differentiated from other less complex forms of imaginative countertransference through examples from clinical practice. The point is that such countertransference experiences may activate the symbolic function in the analyst and thus contribute to the mediation of emergent consciousness in the analysand.
