Manipulation and constitutive luck

Philosophical Studies - I argue that considerations pertaining to constitutive luck undermine historicism—the view that an agent’s history can determine whether or not she is morally...     

Learning from your mistakes: does it matter if you’re out in left foot,I mean field?

Studies have shown that generating errors prior to studying information (pencil–?) can improve target retention relative to passive (i.e., errorless) study, provided that cues and targets are semantically related (pencil–ink) and not unrelated (pencil-frog). In two experiments, we manipulated semantic proximity of errors to targets during trial-and-error to examine whether it would modulate this error generation benefit. In Experiment 1, participants were shown a cue (band–?) and asked to generate a related word (e.g., drum). Critically, they were given a target that either matched the semantic meaning of their guess (guitar) or mismatched it (rubber). In Experiment 2, participants studied Spanish words where the English translation either matched their expectations (pariente–relative) or mismatched it (carpeta–folder). Both experiments show that errors benefit memory to the extent that they overlap semantically with targets. Results are discussed in terms of the retrieval benefits of activating related concepts during learning.     

Adaptation of Neuromuscular Synergies During Intentional Constraints of Space-Time Relationships in Human Gait

Tight frequency-to-amplitude relationships are observed in spontaneous human steady gait. They can be modified, if required; that flexibility forms a fundamental basis of the intentional adaptive capabilities of locomotion. In the present experiments, the processes underlying that flexibility were investigated at both the level of joint kinematics and the level of neuromuscular synergies. Subjects (N = 4) walked at the same speed either with a preferred or a nonpreferred frequency-to-amplitude relationship (i.e., constrained, short steps at a high frequency [COS condition] or constrained, long steps at a low frequency [COL condition]); their swing and stance phases were separately analyzed. In the COS condition, increases in EMG activity were specifically required during the swing phase. In the COL condition, several muscles required increases in EMG activity during the stance phase, but decreases of the hamstring muscles were needed during the swing phase. Whereas, in preferred walking, modification of the frequency affects the EMG patterns globally (the gain increasing with the frequency in both the stance and swing phases), the present results show that changing the frequency in a constrained manner either affects the swing phase specifically or affects both phases, but in the opposite direction. That finding indicates mat a separate control is needed in both the swing and the stance phases.     

What’s ours is yours: recall of history for lesser-known countries is guided by one’s own national history

ABSTRACT

The present studies examine how people recall history. Sometimes, certain national histories are well known and sometimes they are not. We propose that, under certain circumstances, culturally distinctive representations of typical national histories can be used to guide recall, particularly in cases where the history is not well known. We focus on three national samples with varied levels of knowledge about each history: Great Britain, India, and the United States. In Study 1, we establish typical historical event templates for each nation consisting of events that a large proportion of participants from each sample identify as important in a typical nation’s history. We examine points of divergence between the different groups’ typical event templates and the valences of these events. In Study 2, we test and find that, in conditions of less knowledge, participants tend to refer to particular historical events that coincide with events unique to their own group’s typical history. In Study 3, we demonstrate that this effect can be found even when a group possesses a reasonable amount of knowledge about the target country. We conclude by discussing the implications in relation to how such a retrieval strategy might inform interpretations of events in the present.     

Transfer of Skills in the Context of Non‐Suggestive Investigative Interviews: Impact of Structured Interview Protocol and Feedback

Two groups of police investigators were trained in the use of the National Institute of Child Health and Human Development (NICHD) interview protocol. After the training, one group (n = 8) received written feedback on each interview they conducted, whereas the other group (n = 11) did not. The objective of the study was, first, to evaluate the effect of NICHD protocol implementation on the types of questions and details provided by children and, second, to evaluate the impact of post‐training feedback. Interviewees were alleged sexual abuse victims between the ages of 3 and 14 years. Application of the NICHD protocol allowed interviewers to use more open‐ended questions and to obtain more details. The results show that providing feedback significantly increased the quality of the interviews. It is recommended that the NICHD protocol be used to interview child victims and witnesses and that feedback sessions be held with interviewers. Copyright © 2012 John Wiley & Sons, Ltd.     

The Impact of Performance-Contingent Rewards on Perceived Autonomy and Competence

Two studies examined the impact of performance-contingent rewards on perceived autonomy, competence, and intrinsic motivation. Autonomy was measured in terms of both decisional and affective reports. The first study revealed an undermining effect of performance-contingent rewards on affective reports of autonomy among university students, and an increase in reports of competence. Decisional autonomy judgements were unaffected by rewards. The second study replicated this pattern of findings among elementary school children. These results help resolve Cognitive Evaluation Theory's (E. L. Deci & R. M. Ryan, 1985; R. M. Ryan, V. Mims, & R. Koestner, 1983) and Eisenberger, Rhoades, et al.'s (R. Eisenberger, L. Rhoades, & J. Cameron, 1999) divergent positions on the impact of performance-contingent rewards on autonomy. The studies also included measures of intrinsic motivation.     

Parental autonomy-supportive practices and toddlers’ rule internalization: A prospective observational study

Motivational research conducted within self-determination theory suggests that autonomy-supportive (AS) parenting fosters rule internalization, while more controlling tactics hinder it. The goal of the present study is to examine how AS in a socialization context relates to toddlers’ internalization. Toddlers participated in a clean-up and a toy prohibition task at 2 and 3.5 years of age (T1: N?=?102; T2: N?=?85). Their parent’s disciplinary strategies were coded the first year. Toddlers’ committed compliance, indicative of rule internalization, was coded at both time points. After controlling for covariates and initial committed compliance, a linear regression was conducted to predict change in committed compliance over time. As expected, results reveal that parental AS strategies when toddlers were 2 years old were positively related to an improvement in committed compliance from 2 to 3.5 years of age, while controlling strategies predicted deterioration. This prospective, observational study suggests that supporting toddlers’ autonomy in socialization contexts fosters rule internalization.     

Stability of attachment during the preschool period

Children's attachment patterns at early preschool age and 2 years later as well as factors related to stability-instability were examined in a diverse socioeconomic status French Canadian sample of 120 children. Attachment was assessed during 2 laboratory visits using separation-reunion procedures when the children were approximately 3.5 (J. Cassidy & R. S. Marvin, 1992) and 5.5 (M. Main & J. Cassidy, 1988) years old. Overall, stability of attachment, based on 4-way classification, was moderate (68%, k = .47, p = .01). Change from security to disorganization was associated with the most dramatic decline in interactive quality with mother, lowest marital satisfaction, and greatest likelihood of severe attachment-related family events, namely, loss and parental hospitalization. Families of children who changed from security to organized insecurity presented levels of caregiving and marital dissatisfaction that fell between those of stable secure children and secure children who changed toward disorganization.
