What do infants understand of others’ action? A theoretical account of early social cognition

Intention reading and action understanding have been reported in ever-younger infants. However, the notions of intention attribution and action understanding, as well as their relation to each other, are surrounded by much confusion, making it difficult to assess the meaning and value of such findings. In this paper we set out to clarify the notions of ‘action understanding’ and ‘intention attribution’. We will show that what is commonly referred to as ‘action understanding’ in fact encompasses various heterogeneous association and prediction mechanisms. In general, these forms of action understanding will not result in the attribution of an intention to an observed actor. By detaching intention attribution from action understanding, and by exposing the latter as an umbrella notion, we provide a theoretical framework on early social cognition that allows for better comparison of findings from different experimental paradigms, and better assessment of infant action understanding abilities. Taking into account the plurality of forms that action understanding can adopt will help cognitive neuroscience to gain a full understanding of the early roots of social cognition.     

The spatial Stroop effect: A comparison of color-word and position-word interference

The Stroop effect is one of the most famous examples of interference in human perception. The present study demonstrates that a position Stroop paradigm, comparable to the classical color-word interference paradigm, resulted in the same pattern of interference for the spatial dimension; however, the interference was significantly weaker. By exchanging the original oral response for a manual response in the spatial paradigm, we showed that the verbal component is crucial for the Stroop effect: Manual responses lead to a disappearance of the interference effect. Moreover, with manual responses word position was recognized at the same speed for the baseline condition and for words that were incongruent as well as congruent with the spatial position. The results indicate (1) that the Stoop effect depends heavily on verbal components and (2) that differing processing speeds between reading and position recognition do not serve as a proper explanation for the effect. In addition, the provided paradigm plausibly transfers the classical color-word interference to the spatial dimension.     

How and why do infants imitate? An ideomotor approach to social and imitative learning in infancy (and beyond)

It has been proposed that already in infancy, imitative learning plays a pivotal role in the acquisition of knowledge and abilities. Yet the cognitive mechanisms underlying the acquisition of novel action knowledge through social learning have remained unclear. The present contribution presents an ideomotor approach to imitative learning (IMAIL) in infancy (and beyond) that draws on the ideomotor theory of action control and on recent findings of perception–action matching. According to IMAIL, the central mechanism of imitative and social learning is the acquisition of cascading bidirectional action–effect associations through observation of own and others’ actions. First, the observation of the visual effect of own actions leads to the acquisition of first-order action–effect associations, linking motor codes to the action’s typical visual effects. Second, observing another person’s action leads to motor activation (i.e., motor resonance) due to the first-order associations. This activated motor code then becomes linked to the other salient effects produced by the observed action, leading to the acquisition of (second-order) action–effect associations. These novel action–effect associations enable later imitation of the observed actions. The article reviews recent behavioral and neurophysiological studies with infants and adults that provide empirical support for the model. Furthermore, it is discussed how the model relates to other approaches on social-cognitive development and how developmental changes in imitative abilities can be conceptualized.     

DynAOI: A tool for matching eye-movement data with dynamic areas of interest in animations and movies

Analyzing gaze behavior with dynamic stimulus material is of growing importance in experimental psychology; however, there is still a lack of efficient analysis tools that are able to handle dynamically changing areas of interest. In this article, we present DynAOI, an open-source tool that allows for the definition of dynamic areas of interest. It works automatically with animations that are based on virtual three-dimensional models. When one is working with videos of real-world scenes, a three-dimensional model of the relevant content needs to be created first. The recorded eye-movement data are matched with the static and dynamic objects in the model underlying the video content, thus creating static and dynamic areas of interest. A validation study asking participants to track particular objects demonstrated that DynAOI is an efficient tool for handling dynamic areas of interest.     

Spatial updating of dynamic scenes: Tracking multiple invisible objects across viewpoint changes

Research on dynamic attention has shown that visual tracking is possible even if the observer’s viewpoint on the scene holding the moving objects changes. In contrast to smooth viewpoint changes, abrupt changes typically impair tracking performance. The lack of continuous information about scene motion, resulting from abrupt changes, seems to be the critical variable. However, hard onsets of objects after abrupt scene motion could explain the impairment as well. We report three experiments employing object invisibility during smooth and abrupt viewpoint changes to examine the influence of scene information on visual tracking, while equalizing hard onsets of moving objects after the viewpoint change. Smooth viewpoint changes provided continuous information about scene motion, which supported the tracking of temporarily invisible objects. However, abrupt and, therefore, discontinuous viewpoint changes strongly impaired tracking performance. Object locations retained with respect to a reference frame can account for the attentional tracking that follows invisible objects through continuous scene motion.     

Does variability in human performance outweigh imprecision in response devices such as computer keyboards?

In chronometric research, it is well-known that many response devices used with personal computers, especially computer keyboards, suffer from measurement inaccuracies due to infrequent polling. In this article, it is investigated whether it is worth being concerned by this added error, given that human performance inherently exhibits a considerable degree of variability. By comparing inaccuracy due to response device imprecision with the level of variability already present in human performance, it is shown that the former is very unlikely to have a negative impact on statistical outcomes. In other words, millisecond resolution of response devices, although desirable, is not a general requirement.     

Addressing disparities: The impact of a lesbian,gay, bisexual,and transgender graduate counselling course

Background: Lesbian, gay, bisexual and transgender (LGBT) individuals experience serious mental health disparities and treatment inequities. Counsellor education has been identified as both a contributing factor to these problems as well as an ameliorating mechanism to address these inequalities. Aim: The purpose of the current study was to evaluate the impact of an LGBT‐affirmative counselling course. Method: A total of 23 students enrolled in a graduate LGBT counselling course were administered the Sexual Orientation Counselor Competency Scale (SOCCS, Bidell, 2005) and the Lesbian, Gay, and Bisexual Affirmative Counseling Self‐Efficacy Inventory (LGB‐CSI, Dillon & Worthington, 2003) pre‐ and post‐course. In addition, a comparison group of 23 matched counselling students was obtained from an existing data source in order to make further assessments of the course's effectiveness. Those in the comparison group were not enrolled in the LGBT course, but were administered the SOCCS at analogous time intervals. Results: After completing the LGBT course, enrolled students demonstrated significant improvements regarding their sexual orientation counsellor competency and self‐efficacy. In addition, these students showed significant gains in SOCCS scores versus those in the comparison group. Implications: Results from this study show the positive effect a full‐credit LGBT psychotherapy course can have on graduate counselling students' sexual orientation counsellor competency and self‐efficacy. The findings also indicate that such a course can significantly impact counselling skills, a facet of LGBT cultural competency found to be the most attenuated. Findings are discussed in conjunction with LGBT‐affirmative counsellor training and clinical practice.     

Moral and angry emotions provoked by informal social control

Informal social control is the communication of disapproval by one individual to another individual (the perpetrator) who has transgressed a social norm. The present research examined the conditions under which social control provokes moral versus angry emotions in the perpetrator. The roles of perceived deviance and the appraisal of the legitimacy of social control as predictors of these emotions were specifically considered. In two studies, participants imagined themselves in situations in which they engaged in moderately uncivil acts and then received social control (or not). Perpetrators’ perception of the deviance of their behaviour (Studies 1 and 2), and their explicit appraisals of the legitimacy of social control were measured (Study 2). Moral and angry emotions were also assessed. Social control intensified moral and particularly angry emotions, compared to situations in which deviant acts were performed, but no social control was received. In addition, perceived deviance as well as the politeness of the social control importantly influenced angry emotions through their effects on appraised legitimacy.     

Priming the trait category “hostility”: The moderating role of trait anxiety

Recent studies on affective priming with the naming task have revealed an influence of trait anxiety on the direction of affective priming effects (e.g., Berner & Maier, 2004 Berner, M. P. and Maier, M. A. 2004. The direction of affective priming as a function of trait anxiety when naming target words with regular and irregular pronunciation. Experimental Psychology, 51: 180–190. [Crossref], [PubMed], [Web of Science ®] , [Google Scholar]). This moderating role of trait anxiety was further investigated in a study employing a conceptual priming task. After masked presentation of either hostile or neutral primes, participants performed a person judgment task. As expected, the direction of the hostility rating difference score, defined as the difference between hostility ratings of a target person in the hostility priming condition and in the neutral priming condition, changed from positive to negative with increasing levels of self-reported trait anxiety. The findings are interpreted in terms of salience-dependent overcorrection processes (Glaser & Banaji, 1999 Glaser, J. and Banaji, M. R. 1999. When fair is foul and foul is fair: Reverse priming in automatic evaluation. Journal of Personality and Social Psychology, 77: 669–687. [Crossref], [PubMed], [Web of Science ®] , [Google Scholar]). Implications for our understanding of the cognitive functioning in high trait anxiety are discussed.     

The focus of attention in working memory: Evidence from a word updating task

Three experiments examined the cognitive costs of item switching within working memory with a novel word updating task, thereby extending previous research to the field of linguistic stimuli and linguistic-graphemic updating operations. In Experiments 1 and 2 costs for switching between working memory items were evident on the word level, and they increased with an increasing word set size (Experiment 2). In contrast, a surprisingly similar switch effect on the level of letters was not affected by word set size (Experiment 2). Experiment 3 showed that this effect is not simply based on the need for re-orienting visual spatial attention. To account for the overall picture of results, a recursive model of attentional foci is proposed. Moreover, individual working memory span appears to be associated with the accuracy of item switching, but not with its speed.
