Developing and validating a new multi-dimensional scale for anti-social behavior in a higher education setting

The purpose of this research is to construct and validate a multi-dimensional scale of Anti-social Behavior (hereafter ASB) in a Western higher education context (i.e., USA). To achieve this, four studies, each with a different sample, were performed. Study 1 (n = 150) followed an exploratory design to generate a pool of potential items measuring ASB. Study 2 (n = 254) explored the dimensionality of the items produced in Study 1 using exploratory factor analysis (EFA) and reliability measures. Study 3 (n = 654) confirmed the factorial structure from Study 2 and assessed the measurement model invariance using structural equation modeling (SEM). Finally, Study 4 (n = 287) assessed the predictive validity of the ASB measure through testing a hypothetical path model linking ASB to narcissism and Machiavellianism via an SEM procedure. In total, our research findings conclude that the ASB measurement model is a two-factor multi-dimensional structure comprising: Interpersonal Antagonistic Behavior (six items) as well as Indirect Distractive Behavior (four items). The research and practical implications for universities are thereafter discussed.     

Intentional control and implicit sequence learning

Sequence knowledge acquired by repeated exposure to targets in a speeded localization task was studied in 3 experiments that sought to test A. Destrebecqz and A. Cleeremans's (2001, 2003) claim that, under certain circumstances, the expression of such sequence knowledge cannot be brought under intentional control. In Experiment 1 participants were trained on either a deterministic or a probabilistic sequence and then performed a free-generation test under either inclusion or exclusion instructions. Participants were found to be capable of both expressing (inclusion) and avoiding expressing (exclusion) sequence knowledge. These results were confirmed in Experiment 2 with a more exact replication of Destrebecqz and Cleeremans's methodology. In Experiment 3 participants performed a trial-by-trial generation test under both inclusion and exclusion conditions after a much longer period of training. All the findings are consistent with the proposal that information acquired during sequence learning is explicit in nature.     

Relationship between priming and recognition in deterministic and probabilistic sequence learning

Exposure to a repeating sequence of target stimuli in a speeded localization task can support both priming of sequence-consistent responses and recognition of sequence components. In 3 experiments with both deterministic and probabilistic sequences, the authors used a novel procedure in which measures or priming and recognition were taken concurrently and asked whether these measures can be dissociated. In all of these experiments, both measures were above chance at the group level and no evidence of dissociation was found. Item-level analyses of the data in Experiment 3 did reveal dissociations in that (a) recognition judgments were affected by response speed independently of old-new status and (b) items that were not discriminated in recognition nonetheless showed priming. However, the authors show that these data, together with the group-level results, are compatible with a formal model in which priming and recognition are based on a single common memory variable.     

Guilt and self-sacrifice: The plight of the better-off sibling

In this article, the experience of guilt and its behavioral sequelae, self-sacrifice, in the lives of certain therapy clients is explored. Subjects are adults who perceived as children that they were more gified in some area critical to their parents' values than was a sibling. These clients were successful children, but have come to therapy unsuccessful in some crucial area of their adult lives. Their sibling relationship was of primary importance to them. The relationship was very relevant to the lack of adult success they had experienced. Theory is developed to explain this phenomenon, and illustrative case examples are presented and suggestions are made for treatment.     

Incidental picture exposure affects later reading: evidence from the N400

Language comprehenders form a mental representation of the implied shape of objects mentioned in the text. In the present study, the influence of prior visual experience on subsequent reading was assessed. In two separate phases, participants saw a picture of an object and read a text about the object, suggesting the same or a different shape. When the shapes in the two phases mismatched, ERPs during reading showed a larger N400 amplitude than when the shapes matched, suggesting that a picture presented incidentally 15 min earlier affected reading. These results further strengthen the case for the interaction of language and visual experience during language comprehension.     

A continuum of adaptive creative behaviors

Abstract:

The most common definitions of creativity—the production of something new or rare or that of divergent thinking—do not bridge the gap between childhood and adulthood. A developmental continuum is proposed to span the creativity of childhood to the creativity found in adults. The range of adaptive behaviors along this continuum are related by the common element of discontinuity, but differ in adaptation, purpose, novelty, value, speed, and structure. Seven levels are proposed: Learning something new; universal novelty; making connections that are rare compared to peers; developing talents; developing heuristics; producing information; creating by extending a field; and creating by revolutionizing a field. The last two levels are characteristic of mature creators. How educators currently deal with creativity, different developmental trajectories that relate to child‐rearing and schooling practices, a call for supporting creativity as a goal for education, and a brief discussion of the issues of linearity, order, and creativity in females related to the continuum conclude the paper.     

The development of metacognitive ability in adolescence

Introspection, or metacognition, is the capacity to reflect on our own thoughts and behaviours. Here, we investigated how one specific metacognitive ability (the relationship between task performance and confidence) develops in adolescence, a period of life associated with the emergence of self-concept and enhanced self-awareness. We employed a task that dissociates objective performance on a visual task from metacognitive ability in a group of 56 participants aged between 11 and 41 years. Metacognitive ability improved significantly with age during adolescence, was highest in late adolescence and plateaued going into adulthood. Our results suggest that awareness of one’s own perceptual decisions shows a prolonged developmental trajectory during adolescence.     

Activated Self-Concept as a Mechanism Underlying Prevention Message Effects

Recent theorizing has posited that messages influence behavior via currently activated self-concepts. This proposition was tested in the context of evaluating real-world anti-marijuana television ads. A pretest yielded two themes (autonomy and responsibility) with two exemplars each. It was hypothesized that any effects of themes on behavioral willingness to use marijuana would be mediated by accessibility of a nonuser self-concept. An experiment was conducted in which participants (N = 129) viewed one of three clips that 1) contained embedded ads about nonuse supporting autonomy; 2) contained embedded ads about nonuse supporting responsibility to others; or 3) retained original commercials (control). Outcomes included reaction-time measures that assessed nonuser self-concept and willingness to use marijuana in social situations. Among those who identified as not a “druggie” and who were unwilling to smoke a joint at a party with friends, analyses revealed that exposure to the responsibility ads resulted in slower reaction times to endorse these positions, contrary to what might be expected from prevention messages. Among these participants, exposure effects on willingness were mediated by self-concept, as predicted.
