Positive and negative well-being among adolescents from theological and conventional schools in India

In this pilot study, we examined positive and negative well-being among 60 students from theological and conventional schools. Participants included 30 students (50% females) from each school, aged 16–18 years. Self-reported measures included life satisfaction and achievement motivation for positive well-being and stress and anxiety for negative well-being. Results indicated that theological school students reported much lower life satisfaction compared to students in conventional schools with a large effect size. Similar patterns were observed with stress and anxiety, although effects were small. There were no differences in achievement motivation between the two schools. Regarding gender, findings showed that males reported lower stress and anxiety than their female counterparts and these effects were large. Genders did not differ in life satisfaction and achievement motivation.     

The amygdala is involved in the modulation of long-term memory, but not in working or short-term memory

Rats with cannulae implanted in the junction between the central and the basolateral nuclei of the amygdala were trained in one-trial step-down inhibitory avoidance and tested at 3 s for working memory (WM) or 1.5 or 24 h later for short-term memory (STM) and long-term memory (LTM), respectively. Several drugs were infused 6 min prior to training in the animals in which WM was measured or 0 min posttraining in those in which STM and LTM were measured: the glutamate receptor antagonists CNQX (0.5 microg) and AP5 (5.0 microg), the indirect GABA A receptor antagonist picrotoxin (0.08 microg), the cholinergic muscarinic receptor blocker scopolamine (2. 0 microg), norepinephrine (0.3 microg), the protein kinase C inhibitor staurosporin (1.0 microg), or the calcium/calmodulin dependent protein kinase II inhibitor Kn-62 (3.5 ng). None of the drugs had any effect on either WM or STM. All had, as previously shown, strong effects on LTM: picrotoxin and norepinephrine enhanced it, and CNQX, AP5, scopolamine, Kn-62, and staurosporin inhibited it. The results do not support the idea that memory of this task is formed in the amygdala; they indicate that the amygdala is not involved in WM or STM processing and support the idea that the amygdala modulates LTM storage processes carried out elsewhere.     

Effects of posttraining treatments in the posterior cingulate cortex on short- and long-term memory for inhibitory avoidance in rats

Adult male Wistar rats were bilaterally implanted with indwelling cannulae in the caudal region of the posterior cingulate cortex. After recovery, animals were trained in a step-down inhibitory avoidance task (3.0-s, 0.4-mA foot shock) and received, right after training, a 0.5-microl infusion of vehicle (phosphate-buffered saline, pH 7.4), of the GABA(A) receptor agonist muscimol (0.1 or 0.5 microg), of the cAMP-dependent protein kinase (PKA) stimulant Sp-cAMPS (0.1 or 0.5 microg), or of the PKA inhibitor Rp-cAMPS (0.1 or 0.5 microg). Animals were tested twice, 1.5 h and, again, 24 h after training, in order to examine the effects of these agents on short- and long-term memory, respectively. Muscimol (0.5 but not 0.1 microg) hindered retention for both short- and long-term memory (p <.05). Rp-cAMPS (0.1 or 0.5 microg) hindered retention for short-term memory (p <.05). In addition, these animals showed lower, but not significantly lower, latencies than controls in the test session for long-term memory (p >.10). A trend toward an amnesic effect on long-term memory was also observed after Sp-cAMPS infusion at 0.1 microg (p <.10). These results show that strong stimulation of GABAergic synapses in the caudal region of the rat posterior cingulate cortex right after training impairs short- and long-term memory (the latter less dramatically). The same occurs by inhibiting PKA activity with regard to STM and possibly to LTM.     

Mind wandering while reading easy and difficult texts

Mind wandering is a phenomenon in which attention drifts away from the primary task to task-unrelated thoughts. Previous studies have used self-report methods to measure the frequency of mind wandering and its effects on task performance. Many of these studies have investigated mind wandering in simple perceptual and memory tasks, such as recognition memory, sustained attention, and choice reaction time tasks. Manipulations of task difficulty have revealed that mind wandering occurs more frequently in easy than in difficult conditions, but that it has a greater negative impact on performance in the difficult conditions. The goal of this study was to examine the relation between mind wandering and task difficulty in a high-level cognitive task, namely reading comprehension of standardized texts. We hypothesized that reading comprehension may yield a different relation between mind wandering and task difficulty than has been observed previously. Participants read easy or difficult versions of eight passages and then answered comprehension questions after reading each of the passages. Mind wandering was reported using the probe-caught method from several previous studies. In contrast to the previous results, but consistent with our hypothesis, mind wandering occurred more frequently when participants read difficult rather than easy texts. However, mind wandering had a more negative influence on comprehension for the difficult texts, which is consistent with the previous data. The results are interpreted from the perspectives of the executive-resources and control-failure theories of mind wandering, as well as with regard to situation models of text comprehension.     

Refinement and Psychometric Properties of the Eight-Item Brazilian Positive and Negative Affective Schedule for Children (PANAS-C8)

This study aimed to refine the Brazilian Positive and Negative Affect Scale for Children (PANAS-C34). A total of 1,160 children, between seven and 16 years of age (M = 11.2; SD = 1.92), from public elementary schools in eight Brazilian southern cities participated in the study. Four studies were conducted for this project. Study I (n = 370) evaluated the factorial structure of the PANAS-C34 (the original 34-item version). Ten potential items were selected for the instrument’s refined version. Employing an independent sample (n = 340), Study II assessed the utility of this ten-item version. Exploratory factor analysis, parallel analysis, and confirmatory factor analysis supported a bi-factorial solution. However, significant modification indices emerged for two items (happy and sad) regarding their respective factors and thus they were excluded. In Study III, using another independent sample (n = 450), it was demonstrated that the eight-item version (PANAS-C8) had better fit indices than the ten-item version. In Study IV (N = 1,160) a multigroup confirmatory factor analysis was conducted to evaluate the measurement invariance of the factorial solution across gender. Moreover, convergent validity was also evaluated using the Child Depression Inventory (CDI) and the General Life Satisfaction Scale for Children (GLSS-C). Measurement invariance was obtained for the PANAS-C8 across all the investigated model parameters. The correlations between the PANAS-C8 and both the CDI and the GLSS-C were of similar magnitude to those obtained using the PANAS-C34. The PANAS-C8 had adequate validity indices, demonstrating its usefulness in evaluating positive and negative affect in children.     

Development of infant reaching behaviors: Kinematic changes in touching and hitting

This longitudinal study investigated the development of reaching in typical infants, from age 4 to 8 months, and described the pattern of hand kinematics underlying changes in the characteristics of infants’ actions while reaching for a target. Thirteen infants were followed biweekly. Two reaching behaviors emerged during the infants’ free interactions with the target, touching and hitting. Changes over time were documented for the number of movement units, straightness index, distance, peak velocity and time to peak velocity of the hand for touches and hits. We observed increases in the numbers of touches and hits and changes in hand kinematics over time; the distance traveled by the hand was greater for hitting compared to touching. These kinematic changes were specific to the movement patterns that infants adopted to reach to the target.     

Emotions while writing about emotional and non-emotional topics

Research on the effects of expressive writing about emotional experiences and traumatic events has a long history in the affective and social sciences. However, very little is known about the incidence and impact of affective states when the writing activities are not explicitly emotional or are less emotionally charged. By integrating goal-appraisal and network theories of affect within cognitive process models of writing, we hypothesize that writing triggers a host of affective states, some of which are tied to the topic of the essays (topic affective states), while others are more closely related to the cognitive processes involved in writing (process affective states). We tested this hypothesis with two experiments involving fine-grained tracking of affect while participants wrote short essays on topics that varied in emotional intensity including topics used in standardized tests, to socially charged issues, and personal emotional experiences. The results indicated that (a) affect collectively accounted for a majority of the observations compared to neutral, (b) boredom, engagement/flow, anxiety, frustration, and happiness were most frequent affective states, (c) there was evidence for a proposed, but not mutually exclusive, distinction between process and topic affective states, (d) certain topic affective states were predictive of the quality of the essays, irrespective of the valence of these states, and (e) individual differences in scholastic aptitude, writing apprehension, and exposure to print correlated with affect frequency in expected directions. Implications of our findings for research focused on monitoring affect during everyday writing activities are discussed.     

Work ethic and organizational commitment as conditions of unethical pro‐organizational behavior: Do engaged workers break the ethical rules?

Unethical pro‐organizational behaviors (UPB) are actions that break rules or established standards, but are undertaken for the purposes of helping the organization or coworkers. Although research has already examined the role of work ethic and organizational commitment in shaping employee behaviors, little is known about the reason for and antecedents of employees undertaking UPB. In a sample of 425 working adults from multiple industries, we tested whether work ethic and organizational commitment dimensions predict the readiness to undertake UPB. The time‐lagged study showed that the work ethics dimension “hard work,” and normative and affective organizational commitment, are positive predictors of UPB. The ethics dimensions “morality/ethics,” “delay of gratification,” “centrality of work” and “anti‐leisure attitudes” are negative predictors of UPB.     

The Temporal and Dynamic Nature of Self-Regulatory Processes During Independent and Externally Assisted Hypermedia Learning

This study examined the temporal and dynamic nature of students’ self-regulatory processes while learning about the circulatory system with hypermedia. A total of 74 undergraduate students were randomly assigned to 1 of 2 conditions: independent learning or externally assisted learning. Participants in the independent learning condition used a hypermedia environment to learn about the circulatory system on their own, while participants in the externally assisted condition used the same hypermedia environment, but were given prompts and feedback from a human tutor during the session to facilitate their self-regulatory behavior. Previously published pretest–posttest shifts toward more mature understanding of the circulatory system indicate that the externally assisted condition leads to greater learning. The present article uses think-aloud data during learning to explore process issues in light of models of self-regulated learning and conditions of engagement that may affect those processes. Results indicate that access to a human tutor influences the deployment of regulatory processes, intervals of use, and temporal dependencies. For example, there is significantly more planning during the final time interval of the learning session in the externally assisted condition; students in both conditions deploy more learning strategies in the first and second time intervals, compared to the last two time intervals. Additionally, in the externally assisted condition participants were more likely to shift from planning to monitoring and less likely to shift from learning strategies to planning. We discuss theoretical, conceptual, and methodological issues pertaining to these results, as well as implications for future research and the design of adaptive hypermedia systems.
