How crucial is the response format for the testing effect?

Combining study and test trials during learning is more beneficial for long-term retention than repeated study without testing (i.e., the testing effect). Less is known about the relative efficacy of different response formats during testing. We tested the hypothesis that overt testing (typing responses on a keyboard) during a practice phase benefits later memory more than covert testing (only pressing a button to indicate successful retrieval). In Experiment 1, three groups learned 40 word pairs either by repeatedly studying them, by studying and overtly testing them, or by studying and covertly testing them. In Experiment 2, only the two testing conditions were manipulated in a within-subjects design. In both experiments, participants received cued recall tests after a short (~19 min) and a long (1 week) retention interval. In Experiment 1, all groups performed equally well at the short retention interval. The overt testing group reliably outperformed the repeated study group after 1 week, whereas the covert testing group performed insignificantly different from both these groups. Hence, the testing effect was demonstrated for overt, but failed to show for covert testing. In Experiment 2, overtly tested items were better and more quickly retrieved than those covertly tested. Further, this does not seem to be due to any differences in retrieval effort during learning. To conclude, overt testing was more beneficial for later retention than covert testing, but the effect size was small. Possible explanations are discussed.     

Rehabilitation of reading in older individuals with macular degeneration: a review of effective training programs

Macular degeneration (MD) is the most common cause of visual impairment among older adults. It severely affects reading performance. People with MD have to rely on peripheral vision for reading. In this review, we considered several training programs that aim to improve peripheral reading, with a focus on eccentric viewing, oculomotor control, or perceptual learning. There was no strong support in favor of one particular training method for rehabilitation of reading in MD, but there is evidence that older individuals with MD can be trained to improve reading performance, even within limited time.     

Measuring consciousness: task accuracy and awareness as sigmoid functions of stimulus duration

When consciousness is examined using subjective ratings, the extent to which processing is conscious or unconscious is often estimated by calculating task performance at the subjective threshold or by calculating the correlation between accuracy and awareness. However, both these methods have certain limitations. In the present article, we propose describing task accuracy and awareness as functions of stimulus intensity (thus obtaining an accuracy and an awareness curve) as suggested by Koch and Preuschoff (2007). The estimated lag between the curves describes how much stimulus intensity must increase for awareness to change proportionally as much as accuracy and the slopes of the curves are used to assess how fast accuracy and awareness increases and whether awareness is dichotomous. The method is successfully employed to assess consciousness characteristics on data from four different awareness scales.     

Spontaneous goal inferences are often inferred faster than spontaneous trait inferences

We present four experiments in which participants were exposed to texts depicting behaviors that afforded inferences about actors' traits and goals. Results from a false recognition task with varying response deadlines revealed heightened activation of goal inferences already within a 350 ms response deadline. In contrast, trait inferences were made only when there was no response deadline, and when the behavior also implied a goal. These results indicate that spontaneous inferences on goals are often encoded more strongly in memory and are reactivated much more quickly in comparison with spontaneous trait inferences. Moreover, spontaneous trait inferences are often facilitated when an inference is first made on the goal of the behavior. These findings are discussed in light of recent developmental and neuroscientific evidence on social inferences, and current theories on impression formation.     

On the Duties of Commission in Commercial Life. A Kantian Criticism of Moral Institutionalism

In latter-day discussions on corporate morality, duties of commission are fiercely debated. Moral institutionalists argue that duties of commission—such as a duty of assistance—overstep the boundaries of moral duty owed by economic agents. “Moral institutionalism” is a newly coined term for a familiar position on market morality. It maintains that market morality ought to be restricted, excluding all duties of commission. Neo-Classical thinkers such as Baumol and Homann defend it most eloquently. They underpin their position with concerns that go to the core of liberalism—the dominant western political theory that sustains the ideals of both the free market and the free, rational person. Those authors claim that liberalism calls for a fully differentiated market because it resents the politicization of the market. Fully differentiated markets exclude duties of commission. They also claim that full differentiation of the market closes the troublesome gap between moral motivation and moral virtue. Full differentiation redeems the promise of “easy virtue”. In this paper moral institutionalism will be rejected from a Kantian point of view, mostly inspired by Herman’s thesis on the invisibility of morality. Liberalism may perhaps ban the politicization of the market; it does not forbid its moralization. The idea of a fully differentiated market must also be rejected because it is either morally over-demanding (to the morally autonomous person) or morally hazardous (to the person with failing moral motivation). Contrary to what the moral institutionalists claim, right action, morally, is actually quite difficult in fully differentiated markets.     

Social relationships and ambulatory blood pressure: structural and qualitative predictors of cardiovascular function during everyday social interactions.

Healthy normotensive men and women (N = 102) underwent a 3-day ambulatory blood pressure (BP) assessment in which a BP reading was taken 5 min into each social interaction. After each interaction, participants completed a diary that included structural categorization of the relationship and ratings of the quality of the relationship with the interaction partner. Random regression analyses revealed that interactions with family members and spouses were associated with lower ambulatory BP. Interactions with ambivalent network members (characterized by both positive and negative feelings) were associated with the highest ambulatory systolic BP, an effect that was independent of the familial effects on BP. Although there were psychological correlates associated with both structural and functional aspects of relationships, no evidence was found that these mediated the primary findings involving ambulatory BP. These data highlight the influence of both structural and qualitative aspects of relationships on ambulatory BP and possibly health.
