Abstract
The procedural deficit hypothesis claims that impaired procedural learning is at least partly responsible for the deficits in learning to read seen in children with developmental dyslexia. This study used a reading ability-matched design to examine group differences in both procedural and declarative learning. Both children with dyslexia and typically developing children demonstrated procedural learning on a serial reaction time task, although learning in the typically developing group increased at a greater rate towards the end of the task compared with children with dyslexia. However, these results do not provide strong evidence for the procedural deficit hypothesis, because poorer procedural learning in the group with dyslexia may reflect impairments in motor learning, rather than sequence specific procedural learning. In addition, neither group showed a relationship between procedural learning and reading ability.

Abstract
Recent debate about the reliability of psychological research has raised concerns about the prevalence of false positives in our discipline. However, false negatives can be just as concerning in areas of research that depend on finding support for the absence of an effect. This risk is particularly high in unconscious learning experiments, where researchers commonly seek to demonstrate that people can learn to perform a task in the absence of any explicit knowledge of the information that drives performance. The fact that some unconscious learning effects are typically studied with small samples and unreliable awareness measures makes false negatives especially likely. In the present article we focus on a popular unconscious learning paradigm, probabilistic cuing of visual attention, as a case study. First, we show that, at the meta-analytic level, previous experiments reveal positive signs of participant awareness, although individual studies are severely underpowered to detect this. Second, we report the results of 2 empirical studies in which participants' awareness was tested with alternative and more sensitive dependent measures, both of which manifest positive evidence of awareness. We also show that, based on the predictions of a formal model of probabilistic cuing and given the reliabilities of the dependent measures collected in these experiments, any statistical test aimed at detecting a significant correlation between learning and awareness is doomed to return a nonsignificant result, even if at the latent level both constructs are actually related and participants' knowledge is completely explicit.

Abstract
Shanks et al. (2015) challenged the evidence that various forms of decision making can be influenced by romantic/mating primes. In their comment, Sundie, Beal, Neuberg, and Kenrick (2019) question both the meta-analysis and the 8 studies Shanks et al. reported, and describe an alternative p-curve analysis that they interpret as showing that romantic priming is a genuine phenomenon. In this reply, we comment on several contradictions in Sundie et al.'s article. First, they suggest that Shanks et al.'s replication experiments yielded different results from the original studies because we failed to appreciate the contextual sensitivity of romantic priming effects, but this argument rests largely on evidence from the very studies we were unable to replicate, and a wealth of other evidence suggests that social priming effects are largely invariant across samples and settings. Second, Sundie et al. criticize the selection rule by which Shanks et al. identified relevant priming studies, but then go on to include exactly the same set of studies in their p-curve analysis. Third, they criticize Shanks et al.'s selection of statistical results from these studies and propose a much wider selection, but then acknowledge that their selection process is poorly suited to assessing publication bias and p-hacking. Fourth, we show that their p-curve analysis, far from demonstrating that this literature is unaffected by p-hacking, in fact shows the exact opposite. Sundie et al. claim that Shanks et al.'s priming manipulation was demonstrably weak, but their argument is based on a confusion between different dependent measures. We conclude that romantic priming remains unproven, and urge researchers in this field to undertake high-powered preregistered replication studies.

Abstract
Guessing translations of foreign words (hodei?), before viewing corrective feedback (hodei-cloud), leads to better subsequent memory for correct translations than studying intact pairs (hodei-cloud), even when guesses are always incorrect (Potts & Shanks, 2014), but the mechanism underlying this effect is unknown. Possible explanations fall into two broad classes. One puts the locus of the effect at retrieval: Items studied through a generation process have more potential retrieval cues associated with them, or a more distinctive context, and are therefore more accessible at final test. The other puts the locus at encoding and involves enhanced encoding of the correct answer following the generation of an error compared with passive studying (Potts & Shanks, 2014). In 6 experiments we found support for the proposal that generating errors benefits memory through stimulating curiosity to learn correct answers following an incorrect guess, leading to enhanced processing of targets following generation. In Experiment 1, generating possible translations after seeing correct answers did not produce better memory than studying without generating, suggesting that an element of surprise or anticipation is necessary for generating to benefit memory. Experiments 2a-2c found enhanced recognition memory for targets following generating, suggesting increased focus on targets following a guess. In Experiments 3 and 4, participants rated their curiosity to learn correct answers higher when ratings were given after generating than before, suggesting that the act of generation increases curiosity to learn the answers. These findings imply that enhanced processing of feedback is a key consequence of errorful generation. (PsycINFO Database Record (c) 2019 APA, all rights reserved).

Abstract
In recent years evidence has accumulated showing that interim testing of studied information facilitates learning and retrieval of new information-the forward testing effect. In the current article, we review the empirical evidence and putative mechanisms underlying this effect. The possible negative effects of administering interim tests and how these negative effects can be mitigated are discussed. We also propose some important directions for future research to explore. Finally, we summarize the practical implications for optimizing learning and teaching in educational settings.

Abstract
Two experiments examined biases in selective attention during contextual cuing of visual search. When participants were instructed to search for a target of a particular color, overt attention (as measured by the location of fixations) was biased strongly toward distractors presented in that same color. However, when participants searched for targets that could be presented in 1 of 2 possible colors, overt attention was not biased between the different distractors, regardless of whether these distractors predicted the location of the target (repeating) or did not (randomly arranged). These data suggest that selective attention in visual search is guided only by the demands of the target detection task (the attentional set) and not by the predictive validity of the distractor elements.

Abstract
Dijksterhuis and van Knippenberg (1998) reported that participants primed with a category associated with intelligence ("professor") subsequently performed 13% better on a trivia test than participants primed with a category associated with a lack of intelligence ("soccer hooligans"). In two unpublished replications of this study designed to verify the appropriate testing procedures, Dijksterhuis, van Knippenberg, and Holland observed a smaller difference between conditions (2%-3%) as well as a gender difference: Men showed the effect (9.3% and 7.6%), but women did not (0.3% and -0.3%). The procedure used in those replications served as the basis for this multilab Registered Replication Report. A total of 40 laboratories collected data for this project, and 23 of these laboratories met all inclusion criteria. Here we report the meta-analytic results for those 23 direct replications (total N = 4,493), which tested whether performance on a 30-item general-knowledge trivia task differed between these two priming conditions (results of supplementary analyses of the data from all 40 labs, N = 6,454, are also reported). We observed no overall difference in trivia performance between participants primed with the "professor" category and those primed with the "hooligan" category (0.14%) and no moderation by gender.

Abstract
Three experiments investigated whether a process akin to Kamin's (1969) blocking effect would occur with human contingency judgements in the context of a video game. Subjects were presented with sets of trials on each of which they could perform a particular action and observe whether the action produced a particular outcome in a situation in which there was an alternative potential cause of the outcome. In Experiment 1 it was found that prior observation of the relationship between the alternative cause and the outcome did indeed block or reduce learning about the subsequent action-outcome relationship. However, exposure to the relationship between the alternative cause and the outcome after observing the association between the action and the outcome also reduced judgements of the action–outcome contingency (backward blocking), a finding at variance with conditioning theory. In Experiment 2 it was found that, just as is the case with forward blocking, the degree of backward blocking depended on how good a predictor of the outcome the alternative cause was. Finally, in Experiment 3 it was shown that the backward blocking effect was not the result of greater forgetting about the action–outcome relationship in the experimental than in the control condition. These results cast doubt upon the applicability of contemporary theories of conditioning to human contingency judgement.

Abstract
P. W. Cheng's (1997) power PC theory of causal induction proposes that causal estimates are based on the power ( P) of a potential cause, where P is the contingency between the cause and effect normalized by the base rate of the effect. Most previous research using a standard causal probe question has failed to support the predictions of the power PC model but recently Buehner, Cheng, and Clifford (2003) found that participants responded in terms of causal power when probed with a counterfactual test question, which they argued prompted participants to consider the base rate of the effect. However, Buehner et al. framed their counterfactual question in terms of frequency, a factor that has been demonstrated to decrease base rate neglect in judgements under uncertainty. In the experiment reported here, we sought to disentangle the influence of counterfactual and frequency framing of the probe question to determine which factor is responsible for encouraging responses in terms of causal power.

Abstract
Three studies provide convergent evidence that the inverse base-rate effect (Medin & Edelson, 1988) is mediated by rule-based cognitive processes. Experiment 1 shows that, in contrast to adults, prior to the formal operational stage most children do not exhibit the inverse base-rate effect. Experiments 2 and 3 demonstrate that an adult sample is a mix of participants relying on associative processes who categorize according to the base-rate and participants relying on rule-based processes who exhibit a strong inverse base-rate effect. The distribution of the effect is bimodal, and removing participants independently classified as prone to rule-based processing effectively eliminates the inverse base-rate effect. The implications for current explanations of the inverse base-rate effect are discussed.

Abstract
A major topic within human learning, the field of contingency judgement, began to emerge about 25 years ago following publication of an article on depressive realism by Alloy and Abramson (1979). Subsequently, associationism has been the dominant theoretical framework for understanding contingency learning but this has been challenged in recent years by an alternative cognitive or inferential approach. This article outlines the key conceptual differences between these approaches and summarizes some of the main methods that have been employed to distinguish between them.

Abstract
Induction refers to the process in which people generalize their previous experience when making uncertain inferences about the environment that go beyond direct experience. Here we show that interim tests strongly enhance inductive learning. Participants studied the painting styles of eight famous artists across four lists, each comprising paintings by one pair of artists. In an interim test group participants' induction was tested after each list. In two control groups participants solved math problems (interim math group) or studied additional new paintings (interim study group) following each of Lists 1-3 and were asked to classify new paintings on List 4. In the List 4 interim test, the interim test group significantly outperformed the other two groups, indicating that interim testing enhances new inductive learning. In a final cumulative test, accuracy in the interim test group at classifying new paintings by studied artists was nearly double that of the other two groups, indicating the major importance of interim testing in inductive learning. This enhancing effect of interim testing on inductive learning was associated with metacognitive awareness. (PsycINFO Database Record

Abstract
Many studies of unconscious processing involve comparing a performance measure (e.g., some assessment of perception or memory) with an awareness measure (such as a verbal report or a forced-choice response) taken either concurrently or separately. Unconscious processing is inferred when above-chance performance is combined with null awareness. Often, however, aggregate awareness is better than chance, and data analysis therefore employs a form of extreme group analysis focusing post hoc on participants, trials, or items where awareness is absent or at chance. The pitfalls of this analytic approach are described with particular reference to recent research on implicit learning and subliminal perception. Because of regression to the mean, the approach can mislead researchers into erroneous conclusions concerning unconscious influences on behavior. Recommendations are made about future use of post hoc selection in research on unconscious cognition.

Abstract
Wasserman (1990a) has reported an experiment that shows that people's attributions of causality in circumstances where they have to make inferences from brief verbal descriptions correspond to the attributions they make in situations where they actually experience causal sequences, and on the basis of that result he has suggested that psychologists should search for general laws of learning that might account for correspondences such as this one. I briefly describe some further similarities that can be obtained between causal judgments in experienced and described situations. However, the suggestion that a common mechanism may be involved in the two cases is questioned. Instead, I suggest that the correspondence is little more than a coincidence: It does not arise from the operation of a common mechanism. Instead, I argue that people, along with other organisms, possess an associative learning mechanism that operates in experienced situations, but we also possess domain-specific causal beliefs and metabeliefs about causation. These latter two types of beliefs play little role in experienced causal situations, but can readily be applied in making causal attributions from descriptions.

Abstract
The forward testing effect describes the finding that testing of previously studied information potentiates learning and retention of new information. Here we asked whether interim testing boosts self-regulated study time allocation when learning new information and explored its effect on metamemory monitoring. Participants had unlimited time to study five lists of Euskara-English word pairs (Experiment 1) or four lists of face-name pairs (Experiment 2). In a no interim test group, which was only tested on the final list, study time decreased across successive lists. In contrast, in an interim test group, which completed a recall test after each list, no such decrease was observed. Experiments 3 and 4 were designed to investigate the forward testing effect on metamemory monitoring and found that this effect is associated with metacognitive insight. Overall, the current study reveals that interim tests prevent the reduction of study time across lists and that people's metamemory monitoring is sensitive to the forward benefit of interim testing. Moreover, across all 4 experiments, the interim test group was less affected by proactive interference in the final list interim test than the no interim test group. The results suggest that variations in both encoding and retrieval processes contribute to the forward benefit of interim testing. (PsycINFO Database Record

Abstract
Impaired procedural learning has been suggested as a possible cause of developmental dyslexia (DD) and specific language impairment (SLI). This study examined the relationship between measures of verbal and non-verbal implicit and explicit learning and measures of language, literacy and arithmetic attainment in a large sample of 7 to 8-year-old children. Measures of verbal explicit learning were correlated with measures of attainment. In contrast, no relationships between measures of implicit learning and attainment were found. Critically, the reliability of the implicit learning tasks was poor. Our results show that measures of procedural learning, as currently used, are typically unreliable and insensitive to individual differences.

Abstract
Generating errors followed by corrective feedback enhances retention more effectively than does reading-the benefit of errorful generation-but people tend to be unaware of this benefit. The current research explored this metacognitive unawareness, its effect on self-regulated learning, and how to alleviate or reverse it. People's beliefs about the relative learning efficacy of generating errors followed by corrective feedback compared to reading, and the effects of generation fluency, are also explored. In Experiments 1 and 2, lower judgments of learning (JOLs) were consistently given to incorrectly generated word pairs than to studied (read) pairs and led participants to distribute more study resources to incorrectly generated pairs, even though superior recall of these pairs was exhibited in the final test. In Experiment 3, a survey revealed that people believe that generating errors followed by corrective feedback is inferior to reading. Experiment 4 was designed to alter participants' metacognition by informing them of the errorful generation benefit prior to study. Although metacognitive misalignment was partly countered, participants still tended to be unaware of this benefit when making item-by-item JOLs. In Experiment 5, in a delayed JOL condition, higher JOLs were given to incorrectly generated pairs and read pairs were more likely to be selected for restudy. The current research reveals that people tend to underestimate the learning efficiency of generating errors followed by corrective feedback relative to reading when making immediate item-by-item JOLs. Informing people of the errorful generation benefit prior to study and asking them to make delayed JOLs are effective ways to alleviate this metacognitive miscalibration. (PsycINFO Database Record

Abstract
Locating a target among distractors improves when the configuration of distractors consistently cues the target's location across search trials, an effect called contextual cuing of visual search (CC). The important issue of whether CC is automatic has previously been studied by asking whether it can occur implicitly (outside awareness). Here we ask the novel question: is CC of visual search controllable? In 3 experiments participants were exposed to a standard CC procedure during Phase 1. In Phase 2, they localized a new target, embedded in configurations (including the previous target) repeated from Phase 1. Despite robust contextual cuing, congruency effects - which would imply the orientation of attention towards the old target in repeated configurations - were found in none of the experiments. The results suggest that top-down control can be exerted over contextually-guided visual search.

Abstract
When a series of studies fails to replicate a well-documented effect, researchers might be tempted to use a "vote counting" approach to decide whether the effect is reliable-that is, simply comparing the number of successful and unsuccessful replications. Vohs's (2015) response to the absence of money priming effects reported by Rohrer, Pashler, and Harris (2015) provides an example of this approach. Unfortunately, vote counting is a poor strategy to assess the reliability of psychological findings because it neglects the impact of selection bias and questionable research practices. In the present comment, we show that a range of meta-analytic tools indicate irregularities in the money priming literature discussed by Rohrer et al. and Vohs, which all point to the conclusion that these effects are distorted by selection bias, reporting biases, or p-hacking. This could help to explain why money-priming effects have proven unreliable in a number of direct replication attempts in which biases have been minimized through preregistration or transparent reporting. Our major conclusion is that the simple proportion of significant findings is a poor guide to the reliability of research and that preregistered replications are an essential means to assess the reliability of money-priming effects.

Abstract
Two experiments were conducted to explore the role of configural representations in contextual cuing of visual search. Repeating patterns of distractors (contexts) were trained incidentally as predictive of the target location. Training participants with repeating contexts of consistent configurations led to stronger contextual cuing than when participants were trained with contexts of inconsistent configurations. Computational simulations with an elemental associative learning model of contextual cuing demonstrated that purely elemental representations could not account for the results. However, a configural model of associative learning was able to simulate the ordinal pattern of data. (PsycINFO Database Record

Abstract
Interventions aimed at influencing spending behavior and risk-taking have considerable practical importance. A number of studies motivated by the costly signaling theory within evolutionary psychology have reported that priming inductions (such as looking at pictures of attractive opposite sex members) designed to trigger mating motives increase males' stated willingness to purchase conspicuous consumption items and to engage in risk-taking behaviors, and reduce loss aversion. However, a meta-analysis of this literature reveals strong evidence of either publication bias or p-hacking (or both). We then report 8 studies with a total sample of over 1,600 participants which sought to reproduce these effects. None of the studies, including one that was fully preregistered, was successful. The results question the claim that romantic primes can influence risk-taking and other potentially harmful behaviors.
