An above real time training intervention for sport decision making

ObjectivesA speeded video-based decision-making training intervention was used to assess the impact of above real time training on decision-making skill in sport.Design and methodsThree groups completed pre tests and either five weeks of fast speed video training, normal speed video training or no training, followed by a post test and two retention tests in subsequent weeks. Decision accuracy was measured by awarding three, two, one, or no point(s) based on independent coach ratings of each situation.ResultsResults revealed that those trained in above real time improved performance earlier in the training intervention compared to those trained in normal speed. The above real time group also retained more of the performance improvements. The transfer test for decision accuracy showed improvement following the training intervention for all groups, trends in the data reflected a higher retention rate for the fast speed group choosing the bet option more frequently than normal and control groups.ConclusionsThe results lend support to the general use of video-based decision-making training for team invasion sports. A greater impact is that they provide a new paradigm by adapting above real time training to decision making, to create a more game-like training scenario.     

Matching bias in syllogistic reasoning: Evidence for a dual-process account from response times and confidence ratings

We examined matching bias in syllogistic reasoning by analysing response times, confidence ratings, and individual differences. Roberts’ (2005) “negations paradigm” was used to generate conflict between the surface features of problems and the logical status of conclusions. The experiment replicated matching bias effects in conclusion evaluation (Stupple & Waterhouse, 2009), revealing increased processing times for matching/logic “conflict problems”. Results paralleled chronometric evidence from the belief bias paradigm indicating that logic/belief conflict problems take longer to process than non-conflict problems (Stupple, Ball, Evans, & Kamal-Smith, 2011). Individuals’ response times for conflict problems also showed patterns of association with the degree of overall normative responding. Acceptance rates, response times, metacognitive confidence judgements, and individual differences all converged in supporting dual-process theory. This is noteworthy because dual-process predictions about heuristic/analytic conflict in syllogistic reasoning generalised from the belief bias paradigm to a situation where matching features of conclusions, rather than beliefs, were set in opposition to logic.     

Periventricular Leukomalacia (PVL): An Identical Twin Case Study Illustration of White Matter Dysfunction and Nonverbal Learning Disability (NLD)*

This paper discusses the implications of Periventricular Leukomalacia (PVL) lesions for the development of Nonverbal Learning Disabilities (NLD) as illustrated through an identical twin case study. PVL lesions were identified in an 8-year-old child, but were not detected in his identical twin brother who served as a matched comparison. While the nonclinical twin displayed a largely unremarkable neuropsychological profile, the clinical twin evidenced a distinct pattern of social, intellectual, academic, and neuropsychological test results often identified among children with PVL and those with the NLD syndrome. The clinical and theoretical implications for this case study are discussed.     

Fitting an ex-Gaussian function to examine costs in event-based prospective memory: Evidence for a continuous monitoring profile

Event-based prospective memory (PM) tasks require individuals to remember to perform a deferred action when a target event occurs. PM task requirements can slow ongoing task responses on non-target trials (‘costs’) under conditions where the defining features of targets are non-focal to the ongoing task, which is indicative that individuals have allocated some form of cognitive control process to the PM task. Recent fits of the ex-Gaussian mathematical function to non-target trial response distributions by prior studies have indicated that these control processes are transiently allocated. In the current paper, fits of the ex-Gaussian function to data reported by Loft and Humphreys (2012) demonstrate a shift in the entire response time distribution (μ) and an increase in skew (τ) for a non-focal PM condition required to remember to make a PM response if presented with category exemplars, compared to a control condition. This change in μ is indicative of a more continuous PM monitoring profile than that reported by prior studies. In addition, within–subject variability in μ was reliably correlated with PM accuracy, suggesting that these control processes allocated on a regular basis were functional to PM accuracy. In contrast, when the ongoing task directed attention to the defining features of targets (focal PM) there was a trend level increase in μ, but the within–subject variability in μ was not correlated with PM accuracy, consistent with the theoretical premise that focal PM tasks are not as dependent on cognitive control as non-focal PM tasks.     

The Knowledge Rule and the Action Rule

In this paper I compare Timothy Williamson's knowledge rule of assertion with Ishani Maitra and Brian Weatherson's action rule. The paper is in two parts. In the first part I present and respond to Maitra and Weatherson's master argument against the knowledge rule. I argue that while its second premise, to the effect that an action X can be the thing to do though one is in no position to know that it is, is true, its first premise is not: the data do not support the claim that whenever X is the thing for one to do, one is in a position to assert that it is. In the second part I consider Maitra and Weatherson's alternative hypotheses, arguing that they do not provide a better explanation of the linguistic data. I conclude, in particular, that the knowledge rule is preferable to the action rule.     

The reactivation of associated information affects source monitoring

In this study, we examined a source-monitoring phenomenon that arises from reactivated related information from the study phase. Three experiments showed that source attributions for target events were influenced not only by the target item itself, but also by studied information about related items. In Experiment 1, source memory for target items that have a high forward association value to a single related study item (e.g., credit) were affected by the source of the associated information (e.g., card), so that memory performance was better when associated items were presented in the same source rather than a different source. A similar effect occurred with bidirectional associates (Exp. 2), as well as with synonymous pairs of words (Exp. 3). We argue that the source information of the reactivated material can be commingled with information about a candidate during a source judgment at retrieval and thereby can affect performance.     

Internalizing and externalizing dimensions and alcohol use in first time DWI offenders: indirect effects through coping self-efficacy

Using cross-sectional data and structural equation modeling, we evaluated whether coping self-efficacy to abstain from drinking in various situations accounted for the relationship between internalizing (depression, anxiety) and externalizing (aggression, low socialization) dimensions with problematic alcohol use in 292 first-time DWI offenders. Results indicated that an internalizing dimension indirectly predicted problematic alcohol use through coping self-efficacy in negative situations only, whereas an externalizing dimension indirectly predicted problematic alcohol use through coping self-efficacy in positive situations only. These findings support two potential pathways to problematic drinking behavior among DWI offenders and suggest that internalizing and externalizing dimensions may differentially predict high risk drinking situations due to one's inability to abstain in specific situations.     

Children over-imitate adults and peers more than puppets

Researchers commonly use puppets in development science. Amongst other things, puppets are employed to reduce social hierarchies between child participants and adult experimenters akin to peer interactions. However, it remains controversial whether children treat puppets like real-world social partners in these settings. This study investigated children's imitation of causally irrelevant actions (i.e., over-imitation) performed by puppet, adult, or child models. Seventy-two German children (Age_Range = 4.6–6.5 years; 36 girls) from urban, socioeconomically diverse backgrounds observed a model retrieving stickers from reward containers. The model performed causally irrelevant actions either in contact with the reward container or not. Children were more likely to over-imitate adults’ and peers’ actions as compared to puppets’ actions. Across models, they copied contact actions more than no-contact actions. While children imitate causally irrelevant actions from puppet models to some extent, their social learning from puppets does not necessarily match their social learning from real-world social agents, such as children or adults.

Research Highlights

• We examined children's over-imitation from adult, child, and puppet models to validate puppetry as an approach to simulate non-hierarchical interactions.
• Children imitated adults and child models at slightly higher rates than puppets.
• This effect was present regardless of whether the irrelevant actions involved physical contact to the reward container or not.
• In our study children's social learning from puppets does not match their social learning from human models.
