How information guides movement: intercepting curved free kicks in soccer

Previous studies have shown that balls subjected to spin induce large errors in perceptual judgments ( [Craig et al., 2006] and [Craig et al., 2009] ) due to the additional accelerative force that causes the ball’s flight path to deviate from a standard parabolic trajectory. A recent review however, has suggested that the findings from such experiments may be imprecise due to the decoupling of perception and action and the reliance on the ventral system (van der Kamp, Rivas, van Doorn, & Savelsbergh, 2008). The aim of this study was to present the same curved free kick trajectory simulations from the perception only studies ( [Craig et al., 2006] and [Craig et al., 2009] ) but this time allow participants to move to intercept the ball. By using immersive, interactive virtual reality technology participants were asked to control the movement of a virtual effector presented in a virtual soccer stadium so that it would make contact with a virtual soccer ball as it crossed the goal-line. As in the perception only studies the direction of spin had a significant effect on the participants’ responses with significantly fewer balls being intercepted in the spin conditions when compared to no-spin conditions. A significantly higher percentage of movement reversals for the spin conditions served to highlight the link between information specifying ball heading direction and subsequent movement. The coherence of the findings for both the perception and perception/action study are discussed in light of the dual systems model for visual processing.     

Phasic auditory alerting improves visual conscious perception

Attention is often conceived as a gateway to consciousness (Posner, 1994). Although endogenous spatial attention may be independent of conscious perception (CP) (Koch Tsuchiya, 2007), exogenous spatial orienting seems instead to be an important modulator of CP ( [Chica et al., 2010] and Chica, Lasaponara, et al., 2011). Here, we investigate the role of auditory alerting in CP in normal observers. We used a behavioral task in which phasic alerting tones were presented either at unpredictable or at predictable time intervals prior to the occurrence of a near-threshold visual target. We find, for the first time in neurologically intact observers, that phasic alertness increases CP, both objectively and subjectively. This result is consistent with evidence showing that phasic alerting can ameliorate the spatial bias exhibited by visual neglect patients (Robertson, Mattingley, Rorden, & Driver, 1998). The alerting network may increase the activity of fronto-parietal networks involved in top-down amplification required to bring a stimulus into consciousness (Dehaene, Changeux, Naccache, Sackur, & Sergent, 2006).     

Revelation effects in remembering,forecasting, and perspective taking

The revelation effect is a robust phenomenon in episodic memory whereby stimuli that immediately follow a simple cognitive task are more likely to garner positive responses on a variety of memory tests, including autobiographical memory judgments. Six experiments investigated the revelation effect for judgments of past and future events as well as judgments made from others’ perspectives. The purpose of this work was to determine whether these subjectively distinct judgments are subject to the same decision-making biases, as might be expected if they are governed by similar processes (e.g., Schacter, Addis, & Buckner 2007). College-aged participants were asked to rate a variety of life events according to whether the events had occurred during their childhoods or would occur during the next 10 years. Events that followed an anagram task were judged as more likely to have happened in the past and more likely to occur in the future. We also showed a revelation effect when participants were asked to adopt the perspective of others when making judgments about past and future events. When the task was reworded to be non-episodic (participants judged how common the events were during childhood and adulthood), no revelation effect was found for either past or future time frames, which suggests common boundary conditions for both types of judgments. The results are consistent with studies showing strong parallels between remembering and other forms of self-projection but not with semantic memory judgments.     

Dreaming in the multilevel framework

Biological realism ( [Revonsuo, 2001] and [Revonsuo, 2006] ) states that dreaming is a biological phenomenon and therefore explainable in naturalistic terms, similar to the explanation of other biological phenomena. In the biological sciences, the structure of explanations can be described with the help of a framework called ‘multilevel explanation’. The multilevel model provides a context that assists to clarify what needs to be explained and how, and how to place different theories into the same model. Here, I will argue that the multilevel framework would be useful when we try to construct scientific explanations of dreaming.     

“I Feel Your Pain”: The effects of observing ostracism on the ostracism detection system

Ostracism—being ignored and excluded—is a painful experience with negative psychological consequences. Social psychologists ( [Kerr and Levine, 2008] and [Spoor and Williams, 2007] ) argue humans have an evolved system for automatically detecting cues of ostracism and exclusion. Detection elicits pain and threats to fundamental needs. We hypothesize simply observing ostracism will cause negative affect and need threat in the observer. Participants observed a three-player Cyberball game; a target player was included or ostracized, and participants were either instructed to take the perspective of this player or given no such instructions. Participants observing ostracism reported negative affect and need threat. Our results indicate that ostracism detection is even more powerful than previously suggested, because vicariously, we feel the pain of others’ ostracism as our own.     

How to use the diffusion model: Parameter recovery of three methods: EZ, fast-dm, and DMAT

Parameter recovery of three different implementations of the Ratcliff diffusion model was investigated: the EZ model (Wagenmakers, van der Maas, & Grasman, 2007), fast-dm (Voss & Voss, 2007), and DMAT (Vandekerckhove & Tuerlinckx, 2007). Their capacity to recover both the mean structure and individual differences in parameter values was explored. The three methods were applied to simulated data generated by the diffusion model, by the leaky, competing accumulator (LCA) model (Usher & McClelland, 2001) and by the linear ballistic accumulator (LBA) model (Brown & Heathcote, 2008). Results show that EZ and DMAT are better capable than fast-dm in recovering experimental effects on parameters. EZ was best in recovering individual differences in parameter values. When data were generated by the LCA model, the diffusion model estimates obtained with all three methods correlated well with corresponding LCA model parameters. No such one-on-one correspondence could be established between parameters of the LBA model and the diffusion model.     

The learnability of abstract syntactic principles

Children acquiring language infer the correct form of syntactic constructions for which they appear to have little or no direct evidence, avoiding simple but incorrect generalizations that would be consistent with the data they receive. These generalizations must be guided by some inductive bias – some abstract knowledge – that leads them to prefer the correct hypotheses even in the absence of directly supporting evidence. What form do these inductive constraints take? It is often argued or assumed that they reflect innately specified knowledge of language. A classic example of such an argument moves from the phenomenon of auxiliary fronting in English interrogatives to the conclusion that children must innately know that syntactic rules are defined over hierarchical phrase structures rather than linear sequences of words (e.g., [Chomsky, 1965] , [Chomsky, 1971] , [Chomsky, 1980] and [Crain and Nakayama, 1987] ). Here we use a Bayesian framework for grammar induction to address a version of this argument and show that, given typical child-directed speech and certain innate domain-general capacities, an ideal learner could recognize the hierarchical phrase structure of language without having this knowledge innately specified as part of the language faculty. We discuss the implications of this analysis for accounts of human language acquisition.     

Cultural influences on preference consistency: Consistency at the individual and collective levels

Previous research has shown that there are cultural differences in self-concept consistency across situations. However, little is known about cultural differences in preference consistency over time. The present research examined whether Americans are more consistent in their preferences over time than are Japanese. As hypothesized, there were cultural differences in self-reported ( and ) and actual ( and ) preference consistency over time. Further, cultural differences in preference consistency at the individual level (Study 1) were found to aggregate into collective level differences ( and ) in the consistency of preference trends, such as the popularity of baby names. Implications and future directions are discussed.     

An integrated perspective on the relation between response speed and intelligence

Research in the field of mental chronometry and individual differences has revealed several robust regularities (Jensen, 2006). These include right-skewed response time (RT) distributions, the worst performance rule, correlations with general intelligence (g) that are more pronounced for RT standard deviations (RTSD) than they are for RT means (RTm), an almost perfect linear relation between individual differences in RTSD and RTm, linear Brinley plots, and stronger correlations between g and inspection time (IT) than between g and RTm. Here we show how all these regularities are manifestations of a single underlying relationship, when viewed through the lens of Ratcliff’s diffusion model ( [Ratcliff, 1978] and [Ratcliff et al., 2008] ). The single underlying relationship is between individual differences in general intelligence and individual differences in “drift rate”, which is just the speed of information processing in Ratcliff’s model. We also test and confirm a strong prediction of the diffusion model, namely that the worst performance rule generalizes to phenomena outside of the field of intelligence. Our approach provides an integrative perspective on intelligence findings.     

Dreaming and waking: similarities and differences revisited

Dreaming is often characterized as lacking high-order cognitive (HOC) skills. In two studies, we test the alternative hypothesis that the dreaming mind is highly similar to the waking mind. Multiple experience samples were obtained from late-night REM sleep and waking, following a systematic protocol described in Kahan (2001). Results indicated that reported dreaming and waking experiences are surprisingly similar in their cognitive and sensory qualities. Concurrently, ratings of dreaming and waking experiences were markedly different on questions of general reality orientation and logical organization (e.g., the bizarreness or typicality of the events, actions, and locations). Consistent with other recent studies (e.g., [Bulkeley and Kahan, 2008] and [Kozmová and Wolman, 2006] ), experiences sampled from dreaming and waking were more similar with respect to their process features than with respect to their structural features.     

Motivational climate interventions in physical education: A meta-analysis

Objective

The purpose of this study was to synthesize findings from motivational climate interventions employing [Ames, 1992a] and [Ames, 1992b] and [Epstein, 1988] and [Epstein, 1989] TARGET framework within school-based physical education contexts.

Design

The present study employed a quantitative research synthesis design. Meta-analysis uses empirical studies to summarize past research by drawing overall conclusions from separate investigations. This research design highlights important and unsolved issues related to motivational climate interventions within physical education.

Methods

Standard meta-analytic procedures incorporating inclusion and exclusion criteria, literature search, coding procedures, and statistical methods were used to identify and synthesize 22 studies with 24 independent samples. Cohen’s (1988) criteria for effect sizes were used to interpret and evaluate results.

Results

There was an overall small positive treatment effect (g = 0.103) for groups exposed to mastery motivational climates. Outcome analyses identified the most consistent and largest overall treatment effects for behavioral outcomes (g = 0.39–0.49) followed by affective outcomes (g = −0.27 to 0.59) and cognitive outcomes (g = −0.25 to 0.32). Moderator analyses were directed by study heterogeneity and identified several trends in intervention features and study features with the most substantial trend for participant features as elementary students had the largest overall treatment effect (g = 0.41).

Conclusions

Outcome and moderator analyses identified several trends in methodological features, participant features, and study features that should be addressed in future physical education motivational climate interventions.     

The impact of adjacent-dependencies and staged-input on the learnability of center-embedded hierarchical structures

A theoretical debate in artificial grammar learning (AGL) regards the learnability of hierarchical structures. Recent studies using an AⁿBⁿ grammar draw conflicting conclusions (Bahlmann and Friederici, 2006 and [De Vries et al., 2008] ). We argue that 2 conditions crucially affect learning AⁿBⁿ structures: sufficient exposure to zero-level-of-embedding (0-LoE) exemplars and a staged-input. In 2 AGL experiments, learning was observed only when the training set was staged and contained 0-LoE exemplars. Our results might help understanding how natural complex structures are learned from exemplars.     

The personality traits of liked people

There is surprisingly little understanding of how personality traits are associated with being generally liked by others after adolescence (Ozer & Benet-Martinez, 2006). We examined the relationship between self-reported personality traits and being generally liked in young adulthood in Greek organizations and freshman dormitories. We found a high level of consistency in which traits were associated with being liked. We examined the relationship between liked and socially desirable traits, using a recent theory on agency and communion (Wojciszke, Abele, & Baryla, 2009). Results help to create a personality profile of the person who is more liked by others, especially pointing to the importance of communal characteristics that are associated with behavior benefiting others.     

The role of the ventral and dorsal pathways in reading Chinese characters and English words

Previous literature in alphabetic languages suggests that the occipital-temporal region (the ventral pathway) is specialized for automatic parallel word recognition, whereas the parietal region (the dorsal pathway) is specialized for serial letter-by-letter reading ( [Cohen et al., 2008] and [Ho et al., 2002] ). However, few studies have directly examined the role of the ventral and dorsal pathways in Chinese reading compared to English reading. To investigate this issue, we adopted the degraded word processing paradigm used by Cohen et al. (2008) and compared brain regions involved in the processing of degraded Chinese characters and English words during lexical decision, using functional magnetic resonance imaging (fMRI). The degraded characters/words were created by inserting blank spaces between radicals of Chinese characters or syllables of English polysyllabic words. Generally, the current study replicated the effects of Cohen et al. (2008), showing that in Chinese – like in alphabetic languages – character spacing modulates both ventral (bilateral cuneus, left middle occipital gyrus) and dorsal (left superior parietal lobule and middle frontal gyrus) pathways. In addition, the current study showed greater activation in bilateral cuneus and right lingual gyrus for Chinese versus English when comparing spaced to normal stimuli, suggesting that Chinese character recognition relies more on ventral visual-spatial processing than English word recognition. Interestingly, bilateral cuneus showed monotonic patterns in response to increasing spacing, while the rest of the regions of interest showed non-monotonic patterns, indicating different profiles for these regions in visual-spatial processing.     

Les effets de l’ingestion aiguë d’alcool sur le jugement d’expressions faciales émotionnelles spontanées et dynamiques

This study is interested in the link between acute alcohol consumption and the perception of dynamic and spontaneous emotional facial expressions (EFE). The noxious effects of alcohol on EFE recognition are now well demonstrated (Attwood et al., 2009a). Studies showed that alcohol drinking impairs the judgment of facial expressions, especially of negative ones (EFE of anger and disgust notably). However, such effects have been observed for the judgment of artificial material (static/posed/morphed/EFE). Yet, everyday EFE are far from the archetypes used in the lab. Therefore, the present study aims at completing previous observations, this time for the identification of dynamic and spontaneous EFE. Dynamic and spontaneous EFE of amusement, interest, irritation, anxiety, and neutral were judged by 63 normal male drinkers. Buck et al.’s (1972) paradigm was adopted since it is recommended for the study of nonverbal behavior in the process of communication ( [Buck, 1990] , [Wagner, 1990] , [Wagner et al., 1986] and [Zuckerman et al., 1976] ). The emotion to be identified is the one self-reported by the EFE sender. On the pretext of tasting drinks, participants were randomly assigned to one out of six experimental conditions. Two conditions are concerned with the nature of the drink (alcohol or non-alcohol drink). Three other conditions relate to the participant's experimentally manipulated belief regarding the nature of the drink (non-alcohol drink, slight alcohol drink, hard alcohol drink). Results confirm the emotion identification impairment due to alcohol usually noted, thus showing that the effects of alcohol are also observed for the perception of spontaneous and natural facial expressions. Indeed, the comparison of participants who drank alcoholic drinks versus those who did not drink alcohol shows that the formers identify less well emotions than the latter. Moreover, results show that beliefs do not play a role in this deficit since participants’ identification errors are not linked to the belief they hold regarding the nature of the drink (with/without alcohol). Finally, the confusion matrix analysis brings to light the existence of recurrent confusions amongst alcoholized participants, confusions that do not appear amongst sober participants. Thus, results show that, to the exception of EFE of amusement, participants who drank alcohol recurrently assess stimuli as displaying anxiety. To conclude, it comes out that acute alcohol drinking alters the capacity to accurately identify spontaneous emotions expressed by faces, which capacity is essential to the smooth unfolding of human interactions.     

Bulimic symptomatology: the role of adaptive perfectionism, shape and weight concern, and self-esteem

An interactive model implicating high perfectionism, high weight and shape concern, and low self-esteem in the onset and maintenance of bulimic symptoms ( [Bardone et?al., 2000] and [Vohs et?al., 1999] ) has received mixed support. This study aimed to replicate the cross-sectional model in a clinical sample of women with eating disorders, and to investigate whether the model could predict changes in binge eating and purging at the end of treatment. Eating disorder outpatients (n = 353) completed measures of perfectionism, weight/shape concern, self-esteem, and bulimic symptoms at pre-treatment and discharge. Contrary to the hypotheses, the three-way interaction did not predict binge eating or purging cross-sectionally or prospectively as a moderator of psychotherapy outcome. It was concluded that the robustness of the interactive model seems questionable and may be impacted by an inadequate conceptualization of the perfectionism construct.     

Reconnaissance en traduction et homographie interlangue

Several studies on bilingual word recognition have shown effects of word similarity between languages. Cognate words (translation equivalents with identical or near-identical forms like LIBRE in French and Spanish) are generally recognized and translated faster than non-cognates (translation equivalents with different forms). In this study, a translation recognition task (de Groot, 1992) was used in which participants (French-Spanish bilinguals) had to decide whether two words presented on a computer screen were translations or not. In Experiment 1, translation equivalents were identical cognates (same form: CIVIL-CIVIL [civil in Spanish]) and non-cognates (different forms: DANSE-BAILE [dance in Spanish]). All non-translation equivalents had different forms (TABLE [table in French]-AMIGO [friend in Spanish]). We observed a facilitation effect for cognate pairs which were processed faster than non-cognate pairs. In Experiment 2, we used the same material for translation equivalents (cognates and non-cognates) and two types of non-translation equivalents: interlingual homographs (same form but different meanings: CREER [create in French]-CREER [believe in Spanish]) and non-homographic non-translation pairs (different forms between languages) as used in Experiment 1. When the non-translation pairs shared the same form (interlingual homographs), they were rejected more slowly than other non-translation pairs. Moreover, contrary to Experiment 1, due to the presence of interlingual homographs in the experimental lists, the facilitation effect for cognate pairs was not replicated. The results suggest that all homographs (cognates and interlingual homographs) have a special status in bilingual memory (due to their lexical and/or semantic overlap) but their processing also depends on task demands and experimental list composition. Our results are in line with the distributed conceptual feature model of bilingual memory ( [de Groot, 1992] and [van Hell et de Groot, 1998] ). This model can explain facilitation and inhibition effects due to different overlaps between words (in both lexical and semantic levels). However, our results lead us to distinguish identification processes and decisional processes in this task as described in the BIA+ model (Dijkstra and van Heuven, 2002).     

Judging the 'passability' of dynamic gaps in a virtual rugby environment

Affordances have recently been proposed as a guiding principle in perception–action research in sport (Fajen, Riley, & Turvey, 2009). In the present study, perception of the ’passability’ affordance of a gap between two approaching defenders in rugby is explored. A simplified rugby gap closure scenario was created using immersive, interactive virtual reality technology where 14 novice participants (attacker) judged the passability of the gap between two virtual defenders via a perceptual judgment (button press) task. The scenario was modeled according to tau theory (Lee, 1976) and a psychophysical function was fitted to the response data. Results revealed that a tau-based informational quantity could account for 82% of the variance in the data. Findings suggest that the passability affordance in this case, is defined by this variable and participants were able to use it in order to inform prospective judgments as to passability. These findings contribute to our understanding of affordances and how they may be defined in this particular sporting scenario; however, some limitations regarding methodology, such as decoupling perception and action are also acknowledged.     

Remembering and imagining: the role of the self

This study investigated whether temporal clustering of autobiographical memories (AMs) around periods of self-development ( [Rathbone et al., 2008] and [Rathbone et al., 2009] ) would also occur when imagining future events associated with the self. Participants completed an AM task and future thinking task. In both tasks, memories and future events were cued using participant-generated identity statements (e.g., I am a student; I will be a mother). Participants then dated their memories and future events, and finally gave an age at which each identity statement was judged to emerge. Dates of memories and future events were recoded as temporal distance from the identity statement used to cue them. AMs and future events both clustered robustly around periods of self-development, indicating the powerful organisational effect of the self. We suggest that life narrative structures are used to organise future events as well as memories.
