The temporal dynamics of effect anticipation in course of action planning

“Strong” versions of the ideomotor theory of action control claim that anticipations of the environmental effects that actions bring about are mandatory for response selection. This is considered to be the one and only way of how actions can be voluntarily selected. We studied this notion in a series of four experiments where we adapted the flanker paradigm to investigate the involvement of effect codes in the preparation of motor responses. Participants first learned that their responses to stimulus letters were contingently followed by the presentation of a new letter on the screen. In the second phase of the experiments, the action-demanding letters were presented together with the effects of the correct response, effects of other responses, or neutral letters. Varying the stimulus onset asynchrony (SOA) between target stimuli and the flanking effect stimuli provides the opportunity to investigate the temporal dynamics of the activation of effect codes. Hence, flanker stimuli were presented before, simultaneously with, or after the onset of the target. The results indicate that effect-related information from the flanker stimuli is involved in the preparation process, but mainly in later phases of response preparation. The observed pattern of results suggests that, at least under conditions where responses are determined by stimuli, effect codes are activated in course of response planning to enable the evaluation of the executed response and the monitoring of response execution, but they do not automatically activate the responses themselves.     

Infants’ perception of goal-directed actions: A multi-lab replication reveals that infants anticipate paths and not goals

Influential developmental theories claim that infants rely on goals when visually anticipating actions. A widely noticed study suggested that 11-month-olds anticipate that a hand continues to grasp the same object even when it swapped position with another object (Cannon, E., & Woodward, A. L. (2012). Infants generate goal-based action predictions. Developmental Science, 15, 292–298.). Yet, other studies found such flexible goal-directed anticipations only from later ages on. Given the theoretical relevance of this phenomenon and given these contradicting findings, the current work investigated in two different studies and labs, whether infants indeed flexibly anticipate an action goal. Study 1 (N = 144) investigated by means of five experiments, under which circumstances (e.g., animated agent, human agent) 12-month-olds show flexible goal anticipation abilities. Study 2 (N = 104) presented 11-, 32-month-olds and adults both a human grasping action as well as a non-human action. In none of the experiments did infants flexibly anticipate the action based on the goal, but rather on the movement path, irrespective of the type of agent. Although one experiment contained a direct replication of Cannon and Woodward (2012), we were not able to replicate their findings. Overall our work challenges the view that infants are able to flexibly anticipate action goals from early on, but rather rely on movement patterns when processing other’s actions.     

Rats’ anticipation of current and future trial outcomes in the ordered RNR/RNN serial pattern task

In the ordered RNR/RNN serial pattern task, rats often reduce their running speeds on trial 2 less within the RNR than within the RNN series. Initially, investigators (Capaldi, 1985; Capaldi et al., 1983) considered this trial 2 differential speed effect evidence for rats’ anticipation of inter-trial outcomes within each series. Later findings, however, suggest that this effect reflects some generalization of the ordinal position of trial 3 (Burns et al., 1986) or its similar runway cues during trial 2 (Capaldi et al., 1999). To test these generalization hypotheses, we made trial 2 more distinct from trial 3 in each series by forcing rats to alternate runways in a T-maze only on the last trial rather than on trial 2 in each series in Experiment 1, or by forcing rats to alternate runways between trials rather than to run down the same runway on all trials within each series in Experiment 2. Although enhancing the distinctiveness between these trials reduced the trial 2 differential speed effect, extensive training failed to eliminate it. Therefore, this residual difference between trial 2 speeds could reflect rats’ anticipation of trial 3 outcomes during trial 2 as originally proposed by Capaldi (1985) Experiment 3 was designed to determine whether we could enhance rats’ final trial outcome expectancies during trial 2 by making different trial 2 choices distinctive cues for each trial 3 outcome. The trial 2 speed effect was greater when rats were forced to alternate over all trials only within one of the series than when they were sometimes forced to do so in either series. Post-training probe tests revealed that both series position and the relevant within-series runway events contributed to this enhanced anticipation of trial 3 outcomes.     

The phenomenology of virtue

What is it like to be a good person? I examine and reject suggestions that this will involve having thoughts which have virtue or being a good person as part of their content, as well as suggestions that it might be the presence of feelings distinct from the virtuous person’s thoughts. Is there, then, anything after all to the phenomenology of virtue? I suggest that an answer is to be found in looking to Aristotle’s suggestion that virtuous activity is pleasant to the virtuous person. I try to do this, using the work of the contemporary social psychologist Mihalyi Csikszentmihalyi and his work on the ‘flow experience’. Crucial here is the point that I consider accounts of virtue which take it to have the structure of a practical expertise or skill. It is when we are most engaged in skilful complex activity that the activity is experienced as ‘unimpeded’, in Aristotle’s terms, or as ‘flow’. This experience does not, as might at first appear, preclude thoughtful involvement and reflection. Although we can say what in general the phenomenology of virtue is like, each of us only has some more or less dim idea of it from the extent to which we are virtuous—that is, for most of us, not very much.     

Anticipating intentional actions: The effect of eye gaze direction on the judgment of head rotation

Using a representational momentum paradigm, this study investigated the hypothesis that judgments of how far another agent’s head has rotated are influenced by the perceived gaze direction of the head. Participants observed a video-clip of a face rotating 60° towards them starting from the left or right profile view. The gaze direction of the face was either congruent with, ahead of, or lagging behind the angle of rotation. Following this, two static faces, at varying angles of rotation with respect to the end-point angle of the face in the video-clip, were presented simultaneously. The task of the participants was to decide which of the two heads was at an angle best resembling the angle of the end-point of the moving face. The critical test condition consisted of one test face oriented at 10° before, and the other at 10° after the end-point. The ‘lagging behind’ gaze condition elicited a significant underestimation of the rotation compared to the ‘congruent’ and ‘ahead’ gaze conditions. Participants did not exhibit similar biases when judging the rotation of several non-face control stimuli with visual features that mimicked different aspects of gaze direction. The findings suggest that when the gaze direction of a perceived agent is incongruent with the direction of the agent’s head motion observers automatically utilise this discrepancy to adjust their inferences about the agent’s intended heading direction.     

The Influence of Phonological Context on the Sound Errors of a Speaker with Wernicke's Aphasia

A corpus of phonological errors produced in narrative speech by a Wernicke's aphasic speaker (R.W.B.) was tested for context effects using two new methods for establishing chance baselines. A reliable anticipatory effect was found using the second method, which estimated chance from the distance between phoneme repeats in the speech sample containing the errors. Relative to this baseline, error-source distances were shorter than expected for anticipations, but not perseverations. R.W.B.'s anticipation/perseveration ratio measured intermediate between a nonaphasic error corpus and that of a more severe aphasic speaker (both reported in Schwartz et al., 1994), supporting the view that the anticipatory bias correlates to severity. Finally, R.W.B's anticipations favored word-initial segments, although errors and sources did not consistently share word or syllable position.

忧乐圆融：儒家忧乐思想的核心特质

儒家肯定感性忧乐的自然合理性,但是认为感性忧乐有待于外,陷溺于感性忧乐,容易使人流于以物役心的异化状态。儒家忧乐思想的根本形态是德性忧乐,德性忧乐的根据是本心自足之德性。儒家以德性之忧作为德行修养的内在心理动力,德性之乐是在德性彰明过程中本心情感的自然涌现,可以统摄和超越感性忧乐,实现忧乐圆融。     

Curiosity and pathways to well-being and meaning in life: Traits,states, and everyday behaviors

This study examined curiosity as a mechanism for achieving and maintaining high levels of well-being and meaning in life. Of primary interest was whether people high in trait curiosity derive greater well-being on days when they are more curious. We also tested whether trait and daily curiosity led to greater, sustainable well-being. Predictions were tested using trait measures and 21 daily diary reports from 97 college students. We found that on days when they are more curious, people high in trait curiosity reported more frequent growth-oriented behaviors, and greater presence of meaning, search for meaning, and life satisfaction. Greater trait curiosity and greater curiosity on a given day also predicted greater persistence of meaning in life from one day into the next. People with greater trait curiosity reported more frequent hedonistic events but they were associated with less pleasure compared to the experiences of people with less trait curiosity. The benefits of hedonistic events did not last beyond the day of their occurrence. As evidence of construct specificity, curiosity effects were not attributable to Big Five personality traits or daily positive or negative mood. Our results provide support for curiosity as an ingredient in the development of well-being and meaning in life. The pattern of findings casts doubt on some distinctions drawn between eudaimonia and hedonic well-being traditions.
