The effects of interleaving versus blocking on foreign language pronunciation learning

Many studies have shown that students learn better when they are given repeated exposures to different concepts in a way that is shuffled or interleaved, rather than blocked (e.g., Rohrer Educational Psychology Review, 24, 355–367, 2012). The present study explored the effects of interleaving versus blocking on learning French pronunciations. Native English speakers learned several French words that conformed to specific pronunciation rules (e.g., the long “o” sound formed by the letter combination “eau,” as in bateau), and these rules were presented either in blocked fashion (bateau, carreau, fardeau . . . mouton, genou, verrou . . . tandis, verglas, admis) or in interleaved fashion (bateau, mouton, tandis, carreau, genou, verglas . . .). Blocking versus interleaving was manipulated within subjects (Experiments 1–3) or between subjects (Experiment 4), and participants’ pronunciation proficiency was later tested through multiple-choice tests (Experiments 1, 2, and 4) or a recall test (Experiment 3). In all experiments, blocking benefited the learning of pronunciations more than did interleaving, and this was true whether participants learned only 4 words per rule (Experiments 1–3) or 15 words per rule (Experiment 4). Theoretical implications of these findings are discussed.     

A Priori Causal Models of Natural Selection

Plato articulates a deep perplexity about inquiry in ‘Meno's Paradox’—the claim that one can inquire neither into what one knows, nor into what one does not know. Although some commentators have wrestled with the paradox itself, many suppose that the paradox of inquiry is special to Plato, arising from peculiarities of the Socratic elenchus or of Platonic epistemology. But there is nothing peculiarly Platonic in this puzzle. For it arises, too, in classical Indian philosophical discussions, where it is formulated with great clarity, and analysed in a way that casts it in a new light. We present three treatments of the puzzle in Indian philosophy, as a way of refining and sharpening our understanding of the paradox, before turning to the most radical of the Indian philosophers to tackle it. The Indian philosophers who are optimistic that the paradox can be resolved appeal to the existence of prior beliefs, and to the resources embedded in language to explain how we can investigate, and so move from ignorance to knowledge. Highlighting this structural feature of inquiry, however, allows the pessimist philosopher to demonstrate that the paradox stands. The incoherence of inquiry is rooted in the very idea of aiming our desires at the unknown. Asking questions and giving answers rests on referential intentions targeting objects in a region of epistemic darkness, and so our ‘inquiry sceptic’ also finds structurally similar forms of incoherence in the pragmatics of interrogative discourse.     

Semantic information activated during retrieval contributes to later retention: Support for the mediator effectiveness hypothesis of the testing effect

Previous research has proposed that tests enhance retention more than do restudy opportunities because they promote the effectiveness of mediating information--that is, a word or concept that links a cue to a target (Pyc & Rawson, 2010). Although testing has been shown to promote retention of mediating information that participants were asked to generate, it is unknown what type of mediators are spontaneously activated during testing and how these contribute to later retention. In the current study, participants learned cue-target pairs through testing (e.g., Mother: _____) or restudying (e.g., Mother: Child) and were later tested on these items in addition to a never-before-presented item that was strongly associated with the cue (e.g., Father)--that is, the semantic mediator. Compared with participants who learned the items through restudying, those who learned the items through testing exhibited higher false alarm rates to semantic mediators on a final recognition test (Experiment 1) and were also more likely to recall the correct target from the semantic mediator on a final cued recall test (Experiment 2). These results support the mediator effectiveness hypothesis and demonstrate that semantically related information may be 1 type of natural mediator that is activated during testing.     

The Autopsy Imperative: Medicine, Law, and the Coronial Investigation

The central purpose of this paper is to address the tension between legal and medical discourses within the coronial system. Medical expertise, based largely upon internal autopsy, becomes positioned as providing the more important information, rather than the legal model which focuses on evidence gathering at the scene. This paper will examine the aspects of the history, philosophy and consequences of the processes by which the medical model gained its current dominance and will conclude that, while autopsies are necessary, they are also over-used in the coronial system.     

Training family therapy students in conceptual and observation skills relating to the therapeutic alliance: an evaluation

This paper describes a training intervention to develop students' conceptual and observation skills relating to the therapeutic alliance (TA) in family therapy. An evaluation methodology was developed and piloted. The knowledge and observation skills of family therapy students pre‐ and post‐training were assessed in comparison to a non‐intervention group of experienced clinicians. Students' mean scores on the knowledge measure improved significantly from 43 per cent to 74 per cent (p<0.001) and on the observation test from 43 per cent to 65 per cent, although this failed to reach statistical significance (p=0.08). There were no significant changes in the clinicians' scores over the same period. The clinicians' knowledge was higher initially, but the students had caught up after six months. In conclusion, training students in conceptual and observational skills relating to the therapeutic alliance may have a measurable effect. A ‘stepwise’ methodology for demonstrating the relationship between training in TA and outcomes for families is proposed.     

The effects of tests on learning and forgetting

In three experiments, we investigated whether memory tests enhance learning and reduce forgetting more than additional study opportunities do. Subjects learned obscure facts (Experiments 1 and 2) or Swahili-English word pairs (Experiment 3) by either completing a test with feedback (test/study) or receiving an additional study opportunity (study). Recall was tested after 5 min or 1, 2, 7, 14, or 42 days. We explored forgetting by means of an ANOVA and also by fitting a power function to the data. In all three experiments, testing enhanced overall recall more than restudying did. According to the power function, in two out of three experiments, testing also reduced forgetting more than restudying did, although this was not always the case according to the ANOVA. We discuss the implications of these results both for approaches to measuring forgetting and for the use of tests in promoting long-term retention.

Agentic and Communal Generative Behavior in Four Areas of Adult Life: Implications for Psychological Well-Being

Fifty mothers and 48 fathers of soon-to-be-independent children were interviewed to determine how agentic and communal generative themes would be reflected in parenting, occupation, volunteer work, and leisure activities. Mothers reported more communal themes (F5, 83 = 2.32, p <.05). Correlations between generativity and well-being resulted in a negative relationship for mothers in parenting communal generative acts (r = –.41, p = .007) and total generative acts (r = –.3, p = .05) as assessed by the interview. Negative correlations also emerged between mothers' well-being and communal generative acts from the Generative Behavior Checklist, (r = –.33, p = .02).     

Priming third‐party ostracism increases affiliative imitation in children

Human beings are intensely social creatures and, as such, devote significant time and energy to creating and maintaining affiliative bonds with group members. Nevertheless, social relations sometimes collapse and individuals experience exclusion from the group. Fortunately for adults, they are able to use behavioral strategies such as mimicry to reduce their social exclusion. Here we test whether children, too, increase their imitation following an experience of ostracism. Given humans’ profound need to belong, we predicted that the mere hint of social exclusion – even third‐party social exclusion – would be sufficient to increase affiliative imitation in 5‐year‐olds. As predicted, children primed with videos in which one shape was ostracized by a group of other shapes subsequently imitated the actions of a model more closely than children in a control condition. These findings highlight just how sensitive humans are to social exclusion and demonstrate that children, like adults, modify their social behavior in response to ostracism.
