Evaluation of instructional software: Design considerations and recommendations

The elements of desirable research design for the evaluation of educational technology are discussed with reference to the context of existing research. Sources of internal invalidity, type of compared educational activity, and outcome measures are considered. Finally, recommendations regarding the direction of evaluation research are made. Research designs that take into account the characteristics of the learner, the software, and the teacher preferably within the framework of a model of the learning process should be adopted.     

Gender Differences in Parental Coping Following their Child's Death

The impact of the deaths of 19 children from malignancy on subsequent patterns of maternal and paternal coping styles was evaluated in a retrospective study of Dutch parents. The parents had been bereaved on average for 19 months. Parental coping was measured by the Utrecht Coping List which has comparable male and female norm groups. Coping styles differed significantly between the bereaved parents and their respective norm groups, particularly for parents bereaved for 18 months or less. The impact of the loss of a child, in terms of their parents' capacity to cope with everyday problems and events, would appear to affect mothers and fathers rather differently. But fathers and mothers who had been bereaved for more than 18 months were both closer to their comparable coping style norm groups than those bereaved for less than that time.     

Policy analysis and knowledge use

Public policy analysis is a major link in the network of knowledge use. Without analysts’ intermediary role, research would be used less for policy choice and relatively more for predecision enlightenment. However, the knowledge use network may not give enough incentives for researchers to supply needed knowledge or for analysts to seek it. Though Washington, D.C., analysts can seek help from personal networks and from agencies such as the Congressional Research Service, those farther from Washington may use research less effectively. Both groups may also fail to provide incentives for its production (i.e., to overcome academic researchers’ interests in promoting disciplinary theory over practical application). An efficient indexing system for policy-related research might serve as an incentive, if it could help producers of knowledge to be rewarded for its use.     

Bi-directional relations between behavioral problems and executive function: Assessing the longitudinal development of self-regulation

During childhood, the ability to limit problem behaviors (i.e., externalizing) and the capacity for cognitive regulation (i.e., executive function) are often understood to develop in tandem, and together constitute two major components of self-regulation research. The current study examines bi-directional relations between behavioral problems and executive function over the course of childhood and adolescence. Relying on a diverse sample of children growing up in low-income neighborhoods, we applied a random intercept cross-lagged panel model to longitudinally test associations between behavioral problems and executive function from age 4 through age 16. With this approach, which disaggregated between- and within-child variation, we did not observe significant cross-lagged paths, suggesting that within-child development in one domain did not strongly relate to development in the other. We also observed a moderate correlation between the stable between-child components of behavioral problems and executive function over time in our preferred model, suggesting that these two domains may be relatively distinct when modeled from early childhood through adolescence.     

Mechanisms underlying corruption of working memory in Parkinson's disease

Working memory (WM) impairments are reported to occur in patients with Parkinson's disease (PD). However, the mechanisms are unclear. Here, we investigate several putative factors that might drive poor performance, by examining the precision of recall, the order in which items are recalled and whether memories are corrupted by random guessing (attentional lapses). We used two separate tasks that examined the quality of WM recall under different loads and retention periods, as well as a traditional digit span test. Firstly, on a simple measure of WM recall, where patients were asked to reproduce the orientation of a centrally presented arrow, overall recall was not significantly impaired. However, there was some evidence for increased guessing (attentional lapses). On a new analogue version of the Corsi-span task, where participants had to reproduce on a touchscreen the exact spatial pattern of presented stimuli in the order and locations in which they appeared, there was a reduction in the precision of spatial WM at higher loads. This deficit was due to misremembering item order. At the highest load, there was reduced recall precision, whereas increased guessing was only observed at intermediate set sizes. Finally, PD patients had impaired backward, but not forward, digit spans. Overall, these results reveal the task- and load-dependent nature of WM deficits in PD. On simple low-load tasks, attentional lapses predominate, whereas at higher loads, in the spatial domain, the corruption of mnemonic information—both order item and precision—emerge as the main driver of impairment.     

The mediation component of the hopelessness depression in relation to negative life events

A necessary test of the mediational processes component of the hopelessness theory of depression is to test whether the individuals who have negative attributional style and experience negative life events are likely to make negative attributions for the negative events they confront. The present study, using undergraduate students, find that the negative attributional style do not predict negative attributions subjects made for the negative life events they experience within a period of 3 months. However, subjects' negative attributions for the negative life events coupled with the experience of a high number of negative life events predicted their depressive symptomatology. The depressive symptomatology is found not to be mediated through hopelessness. The findings are discussed in relation to the hopelessness theory of depression.     

Assembling Agency: Expression,Action, and Ethics in Deleuze and Guattari’s A Thousand Plateaus

In response to several problems identified in the primary and secondary literature, this article advances an “expressive” conception of action and agency that (i) is consistent with the metaphysics of Deleuze and Guattari’s A Thousand Plateaus, (ii) can underpin the ethical dimensions of this text, and (iii) meets some of the general requirements of a philosophy of action. This conception will be distinguished from standard theories in the philosophy of action, to the extent that these latter conceptualize and explain action with reference to intentions taken as psychological causes that are specifiable in advance and independently of the resultant activity. But it will also be distinguished from commentaries that, after rightly identifying the standard conception of intentional action as incompatible with Deleuze and Guattari’s metaphysics, fail to substitute a viable conception of action and agency in its stead. In short, drawing on a notion of expression, this article will advance a conception of intentions that does not treat them as prior and independently specifiable causes of action, but rather as “immanent” causes whose intelligible content is inseparable from—that is, dynamically assembled and specified within—the ecologically and socially situated, temporally extended and reality-transforming actions they animate.     

The effect of shopping channel (online vs. offline) on message framing of naturalness

Naturalness is a significant driver of food-related choices. However, there is scarce knowledge of how textual cues could be utilised to enhance the effectiveness of naturalness claims. Drawn from construal level theory, we attempted to examine how different methods of framing naturalness affect consumers in online vs. offline shopping contexts. Study 1 employed a 2 (abstract vs. concrete) × 2 (online vs. offline) experiment with 127 respondents and demonstrated that concrete framing heightens positive attitudes via increased perceived concreteness of the message, especially in offline shopping situations. Study 2 employed a 4 (abstract vs. control vs. concrete without mentioning natural vs. concrete mentioning natural) × 2 (online vs. offline) experiment with 173 respondents and replicated findings from Study 1. Furthermore, Study 2 ruled out alternative explanations of message authenticity, transparency and credibility and indicated that the effect of message framings is truly driven by the congruency between consumers' construal level and message framings. Interestingly, no significant effect of abstractly framed naturalness claims was observed in online shopping situations, contradicting existing studies. This suggests that other psychological mechanisms may interplay and hinder the effectiveness of abstract framing in our study. Taken together, the current research demonstrate that consumers' mental representation varies across shopping platforms and how it affects their evaluation of different methods of message framing.
