Providing information about diagnostic features at retrieval reduces false recognition

In the following study, participants encoded blocked DRM word lists and we varied whether they received information before test about the utility of mnemonic features that potentially discriminate between veridical and false memories. The results of three experiments revealed that this manipulation successfully reduced false recognition of critical theme words. We also found that this manipulation was effective for younger but not older adults. Furthermore, calling attention to the features in test instructions alone was sufficient for reducing false recognition and its effectiveness was not enhanced by also asking participants to rate their phenomenal experience. We argue that providing diagnostic information before test allows participants to establish more accurate expectations about the task and thus improves the efficacy of retrieval and monitoring processes that are subsequently engaged.     

Upon Reflection

I report on the fate of three methodological and metatheoretical ideas introduced by Brunswik roughly half a century ago. All were greeted with more than the usual hostility because they challenged the conventional beliefs of the time. All have survived in unexpected ways. I also address certain sins of commission and omission made during the neo-Brunswikian phase of the development of Social Judgement Theory. My hopes and fears for the future are mentioned     

The Effects of Imagery Training on Swimming Performance: An Applied Investigation

A multiple-baseline design was used to examine the influence of an imagery intervention on the performance of swimmers’ times on a thousand-yard practice set. Performance times for four swimmers were collected over a 15-week period during preseason training. The intervention took place over a 3-week period and was introduced after the fourth week of the study. The results revealed that three out of four participants significantly improved their times on the one thousand-yard practice set after being introduced to the imagery intervention. The results are discussed in terms of the implications of using imagery to improve athlete's performance on continuous tasks.     

Is Winning Everything? The Relative Contributions of Motivational Climate and Won-Lost Percentage in Youth Sports

The purpose of this study was to examine the main and interactive effects of motivational climate and won-lost percentage upon young athletes’ evaluations of their coaches, enjoyment of their team experience, and perceived parental liking for the coach. A total of 268 male and female youth basketball players, aged 10 to 15 years, completed the Motivational Climate Scale for Youth Sports (Smith, Cumming, & Smoll, in press) and selected attitudinal scales relating to their sport enjoyment and their evaluations of their coach. Regular season won-lost percentages were calculated for each of the 50 teams. Hierarchical linear modeling was used to predict player evaluations of the coach. Attitudes toward the coach were positively associated with perceptions of a mastery-involved climate and negatively associated with perceptions of an ego-involved climate. Won-lost percentages positively predicted players’ evaluations of their coach's knowledge and teaching ability, but accounted for far less attitudinal variance than did the motivational climate measures. Consistent with earlier findings, young athletes’ sport enjoyment, and evaluations of their coach were more strongly related to coaching behaviors than to their team's won-lost record. No significant interactions involving winning and motivational climate were found.     

Alcohol Use in Three Different Inner Cities in South Africa: AUDIT-C and CAGE

The aim of the present study was to describe the frequency of risky drinking among a general urban population survey (n=1379) in South Africa with the help of (Alcohol Use Disorders Identification Test) AUDIT-C scores, CAGE (Cut down, Annoyed, Guilty, Eye-opener) scores and compare the scores with calculated risky drinking in terms of weekly alcohol consumption or heavy episodic drinking. Results indicate 44.4% for men and 25.4% for women as hazardous or harmful drinkers and using the CAGE 44.7% (55% among men and 35.5% among women). AUDIT-C and CAGE cases were more likely to be women than men and were also more likely among Coloureds and Whites than Black Africans and Indians or Asians. This study showed a greater sensitivity of AUDIT to CAGE.     

The Effect of Motor Preparation on Changes in H Reflex Amplitude During the Response Latency of a Warned Reaction Time Task

Monosynaptic Hoffman reflexes (H reflexes) were recorded from the soleus muscle during the response latency of a warned reaction time (RT) task that required plantarflexion of the foot. The task was done under four conditions of predictability of the response signal (RS), created by the factorial combination of foreperiod duration (1 and 4 s) and variability (fixed and variable). RT varied systematically with RS predictability and was facilitated in conditions that favored prediction of the RS. The response latency was divided into two successive phases by the onset of reflex augmentation: a premotor phase of constant reflex amplitude and a succeeding motor phase marked by progressively increasing reflex amplitude. Reflex augmentation during the motor phase was coupled more closely to the imminent movement than to the preceding signal to respond. The duration of the premotor phase was unaffected by RS predictability, but the duration of the motor phase (like RT) was shorter when the RS was more predictable. The maximum H reflex amplitude reached during the motor phase was greater when the RS was more predictable. The tonic level of H reflex amplitude during the premotor phase was greater in conditions that made prediction of the RS difficult. A second experiment showed that this difference was present throughout the foreperiod.

These results suggest that conditions that favor prediction of the RS enhance motor preparation. Changes in motor preparation (which affect RT) affect the processes underlying reflex augmentation in the motor phase. Enhanced preparation may allow more efficient organization of the descending commands to move, causing higher levels of spinal excitability to be reached in a briefer time. The higher tonic reflex amplitudes in the premotor phase and throughout the preceding foreperiod, in conditions that make prediction of the RS difficult, appear to reflect heightened general arousal.     

When relationships do not live up to benevolent ideals: Women's benevolent sexism and sensitivity to relationship problems

Benevolent sexism promises women a revered place within intimate relationships, which should lead to greater dissatisfaction when they face relationship difficulties. We collected self‐reports of relationship problems and relationship satisfaction (Study 1; N = 91 heterosexual couples), relationship problems and relationship evaluations daily over 3 weeks (Study 1), and hurtful partner behaviour and relationship evaluations over 10 days (Study 2; N = 86 women). Women's endorsement of benevolent sexism predicted sharper declines in relationship satisfaction when they faced greater relationship problems (Study 1) and hurtful partner behaviour (Study 2). These effects were magnified in longer relationships (Studies 1 and 2), indicating that the sensitivity to relationship problems associated with women's endorsement of benevolent sexism is particularly pronounced when women have more invested in their relationship role being revered and cherished. The results suggest that women who endorse benevolent sexism are vulnerable within their relationships because their satisfaction is contingent upon the fulfilment of the promises of benevolent sexism.

From Canon to Dialectic to Antinomy: Giving Inclinations Their Due

In a recent paper, Eckart Förster challenges interpreters to explain why in the first Critique practical reason has a canon but no dialectic, whereas in the second Critique, there is not only a dialectic, but an antinomy of practical reason. In the Groundwork, Kant claims that there is a natural dialectic with respect to morality (4:405), a different claim from those advanced in the first and second Critiques. Förster's challenge may therefore be reformulated as the problem of explaining why practical reason has a canon in the first Critique, a dialectic in the Groundwork, and an antinomy in the second Critique. In this paper, I answer this challenge. I argue that these differences are due to the different aims and scope of the works, and in particular, the different place of the inclinations in their arguments.
