How much attention does an event file need?

Attentional requirements for the spontaneous integration of stimulus and response features were analyzed. In line with previous findings, carrying out a prepared response to the onset of a stimulus created bindings between the response and the features of that stimulus, thereby impairing subsequent performance on mismatching stimulus-response combinations. Findings demonstrate that a stimulus gets bound to a response even if its presence is neither necessary nor useful for the task at hand, it follows rather than precedes the response in time, it competes with a task-relevant stimulus, and if the response is suppressed--but only if the stimulus appears close to the response's eventual execution or abandonment. A multiple-integration model is suggested that assumes that the integration of stimulus features in perception and of response features in action planning are local processes that are independent of stimulus-response integration, which presumably is triggered by the success of the perception-action episode.     

Evaluative conditioning in social psychology: Facts and speculations

The aim of the present paper is to examine the contribution of evaluative conditioning (EC) to attitude formation theory in social psychology. This aim is pursued on two fronts. First, evaluative conditioning is analysed for its relevance to social psychological research. We show that conditioned attitudes can be acquired through simple co-occurrences of a neutral and a valenced stimulus. Moreover, we argue that conditioned attitudes are not confined to direct contact with a valenced stimulus, but can be formed and dynamically reformed indirectly, through association chains. Second, social research is examined in an effort to identify evaluative learning mechanisms. We suggest that several important phenomena in social psychology (e.g., ingroup favouritism, prejudice, name letter effect) are at least partly due to simple mechanisms of evaluative learning. The implications for attitude formation theory and for applied settings are discussed.     

Development of the acquisition and control of action-effect associations

Voluntary action is anticipatory and, hence, must depend on associations between actions and their perceivable effects. We studied the acquisition of action-effect associations in 4-5-vs. 7-year-old children. Children carried out key-pressing actions that were arranged to produce particular auditory effects. In a subsequent test phase, children were to press keys in response to the previous effect sounds, with the sound-key mapping being either consistent or inconsistent with previous key-sound practice. As the processes underlying voluntary action controls are known to significantly improve between 4 and 7 years of age, it was expected that younger children were more prone to automatic effects of acquired sound-key associations. This hypothesis was confirmed, but reaction times and accuracy measures showed different and dissociable patterns. Four-year-olds but not 7-year-olds were more likely to commit an error--i.e., to perform a sound-compatible rather than the correct action--if the sound-key mapping was inconsistent with previous practice. This effect strongly depended on previous practice, suggesting that it reflects long-term learning. In contrast, reaction time effects of mapping consistency did not depend on previous experience but only on the consistency between stimulus and action effect in the present task. Taken altogether, the results suggest that children acquire response-effect associations automatically and that younger children are more likely to suffer from frequent goal neglect; i.e., they tend to forget the current action goal, so that their behavior is dominated by automatic, stimulus-triggered response tendencies.     

Two measures of affect and emotion in Italian children aged 6 to 11 years

The authors investigated the relation between affective and cognitive processes in fantasy play and emotional understanding of 50 Italian children (25 boys and 25 girls) enrolled in regular elementary school in Northern Italy. Children were administered a standardized play task, the Affect in Play Scale, and answered questions about their understanding of emotions. Consistent, yet modest, relationships were found between dimensions of fantasy play and emotional understanding.     

Backward-compatibility effects with irrelevant stimulus-response overlap: the case of the SNARC effect

In 3 dual-task experiments, the relationship between primary-task response (R1) and secondary-task response (R2) was varied. In general, R1-left responses were faster when followed by the word one, and right responses were faster when followed by the word two. This backward-compatibility (BWC) effect indicated (a) that activation of R2 was not delayed until R1 selection was completed, and (b) that activation of the vocal responses was accompanied by the automatic activation of magnitude codes, known to be associated with spatial left-right codes (spatial-numerical association of response codes [the SNARC effect]). These findings supported the hypotheses (a) that BWC effects persist even with irrelevant R1-R2 overlap, (b) that the SNARC effect is based on associations between magnitude and spatial representations underlying response processing, and (c) that the production and perception of magnitudes relies on common codes.     

Disposition to recognize goals in infant chimpanzees

Do nonhuman primates attribute goals to others? Traditional studies with chimpanzees provide equivocal evidence for “mind reading” in nonhuman primates. Here we adopt looking time, a methodology commonly used with human infants to test infant chimpanzees. In this experiment, four infant chimpanzees saw computer-generated stimuli that mimicked a goal-directed behavior. The baby chimps performed as well as human infants, namely, they were sensitive to the trajectories of the objects, thus suggesting that chimpanzees may be endowed with a disposition to understand goal-directed behaviors. The theoretical implications of these results are discussed.     

Confidence judgments in event recall: developmental progression in the impact of question format

Two studies were conducted to examine developmental progression in children's and adults' ability to adequately monitor their own attempts to recall event details as well as the dependence of such metamemorial competencies on question formats. Eight and 10-year-old children as well as adults (Study 1, N=116; Study 2, N=60) rated their confidence when responding to specific questions about an observed event. Confirming most recent results, children and adults gave higher confidence ratings after correct than after incorrect answers. This ability, however, was limited to an unbiased question format. When being asked misleading questions, children's ability to differentiate was undermined, as reflected in equally high confidence judgments after correct and incorrect answers, even when the interview contained a mix of misleading and unbiased questions. When the interviewer "bombarded" the children with an uninterrupted series of misleading questions, children's difficulties appeared to be even more pronounced. These findings highlight the importance of the way in which questions are asked, and point to age-related progression in the relative impact of questioning style.
