With the past behind and the future ahead: Back-to-front representation of past and future sentences
Ulrich R Eikmeier V de la Vega I Ruiz Fernández S Alex-Ruf S Maienborn C 《Memory & cognition》2012,40(3):483-495
Several studies support the psychological reality of a mental timeline that runs from the left to the right and may strongly
affect our thinking about time. Ulrich and Maienborn (Cognition 117:126–138, 2010) examined the linguistic relevance of this timeline during the processing of past- and future-related sentences. Their results
indicate that the timeline is not activated automatically during sentence comprehension. While no explicit reference of temporal
expressions to the left–right axis has been attested (e.g., *the meeting was moved to the left), natural languages refer to the back–front axis in order to encode temporal information (e.g., the meeting was moved forward). Therefore, the present study examines whether a back–frontal timeline becomes automatically activated during the processing
of past- and future-related sentences. The results demonstrate a clear effect on reaction time that emerges from a time–space
association along the frontal timeline (Experiment 1). However, this activation seems to be nonautomatic (Experiment 2), rendering
it unlikely that this frontal timeline is involved in comprehension of the temporal content of sentences. 相似文献

This study investigated the automatic activation of ageism by using a go/no‐go version of the masked evaluative priming task. Pictures of younger persons, of older persons in everyday contexts, and of older persons depicting age‐related conditions of decline were used as masked primes that preceded positive and negative target adjectives conveying either other‐relevant valence (e.g., just and mean) or possessor‐relevant valence (e.g., serene and lonely). The evaluative priming effect (denoting relative negativity of old‐everyday primes in comparison with younger primes) was significant, as hypothesized, only for possessor‐relevant targets. It was not moderated by explicit ageism. A second priming index (denoting relative negativity of old‐decline primes in comparison with old‐everyday primes) predicted, however, explicit ageism. Again, this result was, as expected, constrained to the index based on possessor‐relevant targets. This study provides further evidence that prejudice in terms of automatic evaluations of social stimuli can be more fine grained beyond a mere one‐dimensional positive–negative differentiation.

This study examined empathy-related responding in male adolescents with disruptive behavior disorder (DBD), high or low on
callous-unemotional (CU) traits. Facial electromyographic (EMG) and heart rate (HR) responses were monitored during exposure
to empathy-inducing film clips portraying sadness, anger or happiness. Self-reports were assessed afterward. In agreement
with expectations, DBD adolescents with high CU traits showed significantly lower levels of empathic sadness than healthy
controls across all response systems. Between DBD subgroups significant differences emerged at the level of autonomic (not
verbal or facial) reactions to sadness, with high CU respondents showing less HR change from baseline than low CU respondents.
The study also examined basal patterns of autonomic function. Resting HR was not different between groups, but resting respiratory
sinus arrhythmia (RSA) was significantly lower in DBD adolescents with high CU traits compared to controls. Results support
the notion that CU traits designate a distinct subgroup of DBD individuals. 相似文献

According to the body-specificity hypothesis, people associate positive things with the side of space that corresponds to their dominant hand and negative things with the side corresponding to their nondominant hand. Our aim was to find out whether this association holds also true for a response time study using linguistic stimuli, and whether such an association is activated automatically. Four experiments explored this association using positive and negative words. In Exp. 1, right-handers made a lexical judgment by pressing a left or right key. Attention was not explicitly drawn to the valence of the stimuli. No valence-by-side interaction emerged. In Exp. 2 and 3, right-handers and left-handers made a valence judgment by pressing a left or a right key. A valence-by-side interaction emerged: For positive words, responses were faster when participants responded with their dominant hand, whereas for negative words, responses were faster for the nondominant hand. Exp. 4 required a valence judgment without stating an explicit mapping of valence and side. No valence-by-side interaction emerged. The experiments provide evidence for an association between response side and valence, which, however, does not seem to be activated automatically but rather requires a task with an explicit response mapping to occur. 相似文献

A 121-nation study of societal collectivism and a 174-nation study of political autocracy show that parasitic stress does not account for any variation in these components of culture once the interactive impacts of climatic demands and income resources have been accounted for. Climato-economic livability is a viable rival explanation for the reported effects of parasitic stress on culture. 相似文献

In this study we assess for the first time the driving skills of young adults with developmental coordination disorder (DCD). We use a virtual city and a driving simulator to examine steering control, speed regulation and the responses to pedestrians on the road. Participants were adolescents and young adults who had been diagnosed with the disorder as children. For most participants the symptoms were maintained (DCD group) but for others they had largely dissipated (AD group). We also invited typically developing (control) participants matched in age, gender, and driving experience to the DCD and AD participants. Compared to their matched controls, the DCD group showed difficulties in steering when turning bends but not when driving along straight roads. Although the average speed of the DCD group was similar to their controls this may have been too fast for them to steer effectively around the bends. The DCD group also took 50% more time to react to pedestrians who walked towards their path. We found no such differences between the AD and their matched controls. We discuss the results in terms of visual information processing and suggest further applied and fundamental research on this topic. 相似文献

The role of frontal cortex in selective attention to visual distractors was examined in an attentional capture task in which participants searched for a unique shape in the presence or absence of an additional colour singleton distractor. The presence of the additional singleton was associated with slower behavioural responses to the shape target, and a greater neural signal in inferior frontal gyrus. To investigate the involvement of cognitive control functions of the frontal lobes in the capture of attention by the additional singletons, we measured the effect of the additional singleton in a context of either low or high working memory load. Whereas behavioural capture was unaffected by the level of load on working memory, greater activity associated with the presence of the additional singleton was observed in inferior frontal gyrus, but only under high load. This effect was greater in participants who experienced greater capture. We argue that the role of inferior frontal gyrus in selective attention is to detect potential sources of distraction. 相似文献

The present experimental analogue study used computerised attention training to investigate the role of attention bias in the prediction of intrusive memories. After exposure to a trauma film, participants in a training group (n=22) were presented with a variant of the exogenic cueing task (ECT) in which visual film reminders (i.e., stills from the trauma film) were always presented during invalid and neutral control stimuli always during valid trials. The purpose of this cue-location contingency was reinforcing the direction of attention away from film reminders. Control participants (n=23) performed a similar training without such a contingency. Post-training processing bias was assessed with a single target Rapid Serial Visual Presentation (RSVP) task, in which trauma-film reminders served as task-irrelevant distracters appearing shortly before a neutral target. The frequency of film-related intrusions was recorded in a take-home diary and at a follow-up session three days after film viewing. Participants who underwent attention training reported fewer film-related intrusions and showed less interference by visual film distracters than controls. Implications for research on attention bias after real-life trauma are discussed. 相似文献

The paper presents some speculations on the loss of voluntary responses and operant learning in long-term paralysis in human
patients and curarized rats. Based on a reformulation of the ideomotor thinking hypothesis already described in the 19th century,
we present evidence that instrumentally learned responses and intentional cognitive processes extinguish as a consequence
of long-term complete paralysis in patients with amyotrophic lateral sclerosis (ALS). Preliminary data collected with ALS
patients during extended and complete paralysis suggest semantic classical conditioning of brain activity as the only remaining
communication possibility in those states. 相似文献
