A great number of studies have shown that different motivational and mood states can influence human attentional processes in a variety of ways. Yet, none of these studies have reliably quantified the exact changes of the attentional focus in order to be able to compare attentional performances based on different motivational and mood influences and, beyond that, to evaluate their effectivity. In two studies, we explored subjects' differences in the breadth and distribution of attention as a function of motivational and mood manipulations. In Study 1, motivational orientation was classified in terms of regulatory focus (promotion vs. prevention) and in Study 2, mood was classified in terms of valence (positive vs. negative). Study 1 found a 10% wider distribution of the visual attention in promotion-oriented subjects compared to prevention-oriented ones. The results in Study 2 reveal a widening of the subjects' visual attentional breadth when listening to happy music by 22% and a narrowing by 36% when listening to melancholic music. In total, the findings show that systematic differences and casual changes in the shape and scope of focused attention may be associated with different motivational and mood states.  相似文献

The objectives of the current study were: (a) to determine whether perception–action coupling controlled behaviours when walking through moving doors and (b) to determine how vision contributed to this behaviour. Participants (N = 6) walked along a 7-m path toward two motor-driven doors, which moved at rates ranging between 20 and 40 cm/s. Each door was independently driven such that both moved at the same velocity (symmetrical) or at different velocities (asymmetrical). The results showed that in both door movement conditions the participants controlled their approach velocity by slowing down prior to crossing the doors. The decrease in walking velocity produced greater velocity variability in the final stages prior to crossing the doors and high success rates. The results from the gaze behaviours showed that fixation durations were significantly longer when the doors moved asymmetrically, suggesting that the visual information from this unpredictable environment took longer to process. However, the fixation patterns were similar between the two door movement conditions. Regardless of the door movement condition, the participants spent about 60% of each trial fixating environmental objects (i.e., left door, right door, or aperture). The majority of fixations were directed towards one of the doors at the beginning of the trial and then shifted towards the aperture in the final phase. The participants were using perception–action coupling to control their behaviours in the final phase in order to steer locomotion through the aperture.  相似文献

ObjectiveThis study sought to investigate the dynamics of attentional focus and cognitive control during endurance activity from a metacognitive perspective. The study also intended to examine the situational factors which may influence cognitive strategy use by elite endurance runners.DesignSemi-structured qualitative interviews were utilised.MethodTen elite-level endurance runners were interviewed to explore retrospectively their attentional focus and cognitive strategy use during endurance running.ResultsThe findings revealed that metacognitive strategies such as planning, monitoring, reviewing and evaluating, and metacognitive experiences were fundamental to cognitive control and cognitive strategy use in elite endurance runners. The findings also added to the array of active self-regulatory strategies previously reported in the literature.ConclusionsThese results suggest that metacognitive processes are central to effective cognitive control in elite endurance athletes during running. The findings allowed for the development of an integrative metacognitive framework, which incorporates dimensions of attentional focus. This model may better represent the processes which underpin cognitive control and determine cognitive strategy use in elite athletes during endurance running.  相似文献

ABSTRACT

Previous research has identified experiential avoidance (EA) as related to a host of adolescent internalizing and externalizing problems, as well as borderline personality disorder, suggesting that it is a crosscutting factor for adolescent psychopathology. It remains unclear whether EA differs among adolescents with BPD compared to adolescents with other psychiatric disorders and healthy adolescents. The aims of this study were to 1) examine EA in adolescents with BPD compared to non-BPD inpatient adolescents and healthy adolescents, and 2) to evaluate whether EA has a unique relationship to borderline pathology over and above internalizing and externalizing. Self-report measures of BPD features, EA, and psychopathology were completed by 692 adolescents (64.5% female, Mage= 15.20). This sample included a group of psychiatric inpatient youth (n = 197 BPD; n = 403 non-BPD) and a group of healthy adolescents (n = 92). Results revealed that EA differed significantly across all three groups, with the highest level of EA evidenced in adolescents who had BPD. Furthermore, there was a significant, unique association between BPD symptoms and EA over afnd above internalizing and externalizing pathology. These findings pinpoint EA as an important risk marker and possible target of prevention or intervention for adolescent BPD.  相似文献

ABSTRACT

Observability of threat-related spatial attentional biases may require previous-trial responses associated with threat-related locations. This carryover effect might affect reliability and correlations. In Study 1, a diagonalized Visual Probe Task was completed online (N=131) with colour, anger, fear and disgust stimuli, with questionnaires on aggression, anxiety, depression and impulsivity. Bias towards negative stimuli was found only following previous targets on the negative location. Study 2 aimed to test an interpretation in terms of cue-evoked attention. Task variants were completed (N=101) with and without removal of the cue when targets appeared. Anger and disgust stimuli and aggression, anxiety and depression scales were used. Carryover was replicated with no interaction with cue offset. Over both tasks, reliability was low and no robust correlations with questionnaires were found. Carryover thus determined whether attentional bias to negative facial expressions was observed, but analyses taking this into account did not improve reliability or reveal correlations.  相似文献

Background and objectives: Previous studies have not consistently concluded whether high-anxious persons exhibit attentional bias towards negative natural auditory stimuli. The present study explores whether auditory negative stimuli could induce attentional bias to negative sounds in real life and investigates the exact nature of these biases using an emotional spatial cueing task.

Design: Experimental study with a mixed factorial design.

Method: We created two groups according to the state-trait anxiety scale, namely high and low trait anxiety. Participants (N?=?68 undergraduate students) were required to respond to an auditory target after receiving a negative (aversive sounds from natural life) or neutral auditory stimuli.

Results: A 2 (Validity: valid/invalid)?×?2 (Cue Valence: negative/neutral)?×?2 (Anxiety Group: LA/HA) repeated-measures ANOVA on reaction times revealed that participants with high trait anxiety exhibited slower reaction times in invalid trials following negative cues than following neutral cues. Higher levels of trait anxiety were associated with more difficult attentional disengagement from negative auditory information.

Conclusions: The results demonstrate that impaired attentional disengagement was one of the mechanisms by which high-anxious participants exhibited auditory attentional bias to natural negative information.  相似文献

Pictures of emotionally neutral, positive, and negative (threat‐ or harm‐related) scenes were presented for 3 seconds, paired with nonemotional control pictures. The eye fixations of high and low trait anxiety participants were monitored. Intensity of stimulus emotionality was varied, with two levels of perceptual salience for each picture (colour vs. greyscale). Regardless of perceptual salience, high anxiety was associated with preferential attention: (a) towards all types of emotional stimuli in initial orienting, as revealed by a higher probability of first fixation on the emotional picture than on the neutral picture of a pair; (b) towards positive and harm stimuli in a subsequent stage of early engagement, as shown by longer viewing times during the first 500 ms following onset of the pictures; and with (c) attention away from (i.e., avoidance) harm stimuli in a later phase, as indicated by shorter viewing times and lower frequency of fixation during the last 1000 ms of picture exposure. This suggests that the nature of the attentional bias varies as a function of the time course in the processing of emotional pictures.  相似文献
